Therefore, in the tower-type POS register (vertically integrated type), when the change machine and the scanner unit are arranged in consideration of the operability and work efficiency of the operator, the scanner unit is arranged close to the vertical direction of the change machine. It will be. However, when a trouble such as a coin jam occurs in the change machine, the operator pulls the change machine substantially horizontally to the operator side, then opens the upper cover of the change machine, and removes the money jammed in the change machine ( Maintenance) must be performed. In that case, there was a problem that the opened upper lid collided with the scanner unit and was damaged. In addition, since the scanner unit is arranged close to the upper part of the change machine in the vertical direction, it is necessary to pull out the change machine substantially horizontally to the operator side so that the upper cover of the change machine can be opened reliably. When the distance for pulling out the change machine approximately horizontally to the operator side is insufficient, there is a problem that the cover of the change machine cannot be opened because the scanner unit is in the way. Also, when performing maintenance such as periodically cleaning a transport path for transporting coins and banknotes when depositing and withdrawing from a change machine, the scanner unit becomes an obstacle due to the above problem.
Furthermore, in order to reliably open the upper cover of the change machine, it is necessary to add a space for the distance from which the change machine is pulled out substantially horizontally to the operator work space, and to provide the work space in advance. There is a problem that the number of POS registers that can be installed is reduced in order to secure a large work space for the operator. Therefore, it has been difficult to place the scanner unit used in the tower type POS register close to the vertical direction of the change machine.

The RAM 24 stores the product file (department, barcode information, product name, production area / manufacturer name, price, etc.) of the product purchased by the customer, member file (member code, customer name, privilege, etc.), purchase of the product purchased by the customer. This is a memory for storing and storing data (product details, purchase points, total amount, etc.), a performance file for collecting the purchase data and storing it as sales information.

  The fixed scanner unit 4 reads the barcode information attached to the product purchased by the customer and outputs the barcode information to the CPU 21. An installation form of the fixed scanner unit 4 in the present embodiment will be described with reference to FIG. In the fixed scanner unit 4, an arm protrudes from above the fixed scanner unit 4, and a rotatable roller is attached to the tip of the arm. A scanner suspension base 31 having a wall surface provided with a movable rail 34 that is located above the fixed scanner section 4 and that can slide in mesh with the rollers of the fixed scanner section 4 is disposed. The fixed scanner unit 4 can be moved in the front-rear direction facing the operator (see the moving direction 35 of the fixed scanner unit in FIG. 3) by a roller that meshes with the moving rail 34. The movement of the fixed scanner unit 4 may be either manual or mechanical control, and the fixed scanner unit 4 is moved according to the determination of the CPU 21.

Next, a method for moving the scanner unit according to the present embodiment will be described with reference to FIG. Two electromagnetic solenoids 32 with sheet metal 33 are attached inside a scanner suspension base 31 that suspends the fixed scanner unit 4. Two holes are provided in the wall surface in contact with the fixed scanner unit 4, and the CPU 21 causes the sheet metal 33 coupled to the movable core of the electromagnetic solenoid 32 to flow from the hole of the scanner suspension base 31 by passing a current through the electromagnetic solenoid 32. Control of either protruding control or immersion control is performed. As a result, as shown in FIG. 4A, the fixed scanner unit 4 is moved backward facing the operator, or the movement is prohibited.
The reflective photosensor unit 22 (not shown in FIGS. 3 and 4) is installed on the scanner suspension 31 and detects the fixed scanner unit 4 when the fixed scanner unit 4 is located at the initial position. can do.
When the fixed scanner unit 4 is present at the initial position 41, the photo sensor unit 22 outputs information indicating that it is present at the initial position to the CPU 21.

Further, the automatic change bill machine 7 outputs a normal signal (for example, an error status value: 0) to the CPU 21 when a trouble such as a coin or banknote jamming is eliminated.
Further, the automatic change bill machine 7 outputs an error signal or a normal signal (for example, error status value 1 or 0, respectively) based on an inquiry signal input from the CPU 21.
Moreover, the automatic change fishing ticket machine 7 is placed on the mounting table, and when the automatic change fishing ticket machine 7 has a trouble such as a coin or banknote clogged inside, the operator is placed on the mounting table. Maintenance is performed by pulling out the automatic change bill machine 7 together with the mounting table to the front of the operator.
Moreover, the automatic change bill machine 7 outputs the deposit information of the money deposited from the coin deposit port 7-2 and the bill deposit / withdrawal port 7-3 to the CPU 21.
Moreover, the automatic change bill machine 7 withdraws the banknotes and coins from the banknote deposit / withdrawal port 7-3 and the coin withdrawal port 7-1 according to the type and number of banknotes and coins to be withdrawn input from the CPU 21, respectively. To do.

Next, the accounting process of the CPU 21 will be described. The CPU 21 calls the corresponding product information (product name, unit price, etc.) based on the code information attached to the product read by the fixed scanner unit 4 or the wond scanner unit 5, and inputs the product information and the input unit 3. From the number of products purchased by the customer, the transaction details of the customer are aggregated to calculate the total amount of accounting, the transaction details and the total amount are stored in the RAM 24, and the display unit with touch panel 2 and the customer side display To display.
Then, the CPU 21 calculates the change of the customer from the deposit (payment information) deposited from the customer input from the automatic change bill machine 7 and the total amount of one transaction read from the RAM 24. Next, when the current total key of the input unit 3 is pressed, the CPU 21 withdraws money from the calculated change amount from the coin withdrawal port 7-1 and the banknote deposit / withdrawal port 7-3 and delivers it to the customer. The type and number of bills and coins (changes) (hereinafter referred to as inquiry signals) are output to the automatic change bill machine 7.
Then, when the change for handing over to the customer is correctly withdrawn from the automatic change billboard 7, the CPU 21 stores the purchase details of the customer stored in the RAM 24, the total amount of one transaction, the deposit from the customer, the customer After the change amount and the like handed over to the printing unit 6 is printed out and issued, the transaction information of the customer is stored in the result file area of the RAM 24 as the result data of the day.

Next, examples of the present invention will be described as follows.
The CPU 21 controls the fixed scanner unit 4 to move by the following three implementation methods (referred to as manual, semi-automatic, and fully automatic, respectively). In the first embodiment (manual), the operator manually moves the fixed scanner unit 4 and moves the fixed scanner unit 4 up and down from the retracted position 42 to the initial position 41 (hereinafter referred to as return). The fixed scanner unit 4 is controlled to be moved by operating a button displayed on the front panel portion 2 with a touch panel. The second embodiment (semi-automatic) is a method in which the fixed scanner unit 4 is manually moved, but the CPU 21 controls the start time of the vertical movement of the sheet metal 33 at the time of return. In the third embodiment (fully automatic), when the operator presses a button displayed on the display unit 2 with a touch panel, the CPU 21 controls the start time of the vertical movement of the sheet metal 33 when the fixed scanner unit 4 moves and returns. Is the method. Hereinafter, each example will be described.

[Example 1]
First, as a first embodiment, a control method by the CPU 21 when the fixed scanner unit 4 is manually moved will be described. The flow of processing for controlling the CPU 21 to move the fixed scanner unit 4 from the initial position 41 to the retracted position 42 will be described with reference to the flowchart of FIG. When the current key of the input unit 3 is pressed, the CPU 21 outputs a signal for paying the change bill to the automatic change fishing ticket machine 7 based on the calculated change amount, and the automatic change fishing ticket machine 7 outputs the signal. Wait for the payout result. At that time, if a trouble such as coins or banknotes is jammed inside the automatic change fishing bill machine 7, an error signal (for example, error status value 1) is input from the automatic change fishing ticket machine 7 to the CPU 21. (Step S51 YES). The CPU 21 displays a “save” button on the display unit 2 with a touch panel based on the error signal input from the automatic change bill machine 7 (step S52). Note that when the POS register is in the maintenance mode, a “save” button may be displayed on the display unit 2 with a touch panel. As a result, the operator can be informed that the fixed scanner unit 4 must be moved.

  When the “evacuation” button has been pressed (YES in step S53), the display unit with a touch panel 2 outputs to the CPU 21 information that the withdrawal button has been pressed. When the information is input, the CPU 21 raises the sheet metal 33 coupled to the movable core of the electromagnetic solenoid 32 by passing a current through the electromagnetic solenoid 32 and pulling the electromagnetic solenoid 32 (step S54). Next, the CPU 21 deletes the “save” button of the display unit 2 with a touch panel. Thereafter, the operator pushes the fixed scanner unit 4 by hand, and moves the fixed scanner unit 4 from the initial position 41 to the retracted position 42 along the moving rail 34.

  It should be noted that step S51 does not require any inquiry to the automatic change fishing ticket machine 7 by the CPU 21, but when an inconvenience such as coins or banknotes are jammed inside the automatic change fishing ticket machine 7, the automatic change fishing ticket machine 7 may output an error signal to the CPU 21.

  Next, a flow of processing for controlling the CPU 21 to manually move (return) the fixed scanner unit 4 from the retracted position 42 to the front initial position 41 will be described with reference to the flowchart of FIG. First, when the trouble of the automatic change fishing ticket machine 7 is resolved (step S61 YES), the automatic change fishing ticket machine 7 outputs a normal signal (for example, the error status value is 0) to the CPU 21, and the CPU 21 displays a display unit with a touch panel. 2 displays a “return” button (step S62). Next, the operator manually moves the fixed scanner unit 4 to the initial position (step S63).

  Next, when the operator presses the “return” button (YES in step S64), the display unit with a touch panel 2 outputs information indicating that the return button has been pressed to the CPU 21. The CPU 21 outputs an inquiry signal to the automatic change bill machine 7 based on the input information. The automatic change machine 7 to which the inquiry signal is input outputs a normal signal (for example, error status value: 0) to the CPU 21. Next, based on the normal signal input from the automatic change bill 7, the CPU 21 applies a current to the electromagnetic solenoid 32 to lower the sheet metal 33 (step S 65).

[Example 2]
Next, Embodiment 2 in which the fixed scanner unit 4 is manually moved, and the CPU 21 controls the start time of the vertical movement of the sheet metal 33 at the time of return will be described. Regarding the flow of processing for controlling the CPU 21 to move (retreat) the fixed scanner unit 4 from the initial position 41 to the retreat position 42, the processing from step S51 to step S55 in FIG. 5 is the same as that in the first embodiment (manual). is there.

Next, the flow of processing for returning the fixed scanner unit 4 to the initial position 41 semi-manually will be described with reference to the flowchart of FIG. First, the processing from step S71 to step S73 is the same as the processing from step S61 to step S63 in FIG. Next, when the photo sensor unit 22 senses that the fixed scanner unit 4 is in the initial position (YES in step S74), the photo sensor unit 22 informs the CPU 21 that the fixed scanner unit 4 is in the initial position. Is output. Based on the information input from the photo sensor unit 22, the CPU 21 outputs an inquiry signal to the automatic change bill machine 7. Based on the inquiry signal input from the CPU 21, the automatic change bill machine 7 outputs a normal signal (for example, the error status value is 0) to the CPU 21. Next, based on the normal signal input from the automatic change bill machine 7, the CPU 21 applies a current to the electromagnetic solenoid and lowers the sheet metal 33 (step S <b> 75). Next, the CPU 21 deletes the “return” button displayed on the display unit 2 with a touch panel (step S76).
In this embodiment, the CPU 21 determines based on the output value from the photosensor unit 22 that the fixed scanner unit 4 exists at the retracted position or the initial position. Instead of 22, a contact switch may be used to determine that the CPU 21 exists at the retracted position or the initial position based on the ON / OFF signal of the contact switch.

[Example 3]
Next, as a third embodiment, a control method by the CPU 21 when the CPU 21 controls to move the fixed scanner unit 4 mechanically will be described. A flow of processing for controlling the CPU 21 to move (retreat) the fixed scanner unit 4 from the initial position 41 to the retreat position 42 will be described with reference to FIG. The processing from step S51 to step S54 is the same as that in the first embodiment (manual).

The structure (not shown) for mechanically moving the fixed scanner unit 4 may be as follows. The structure is attached to the upper surface of the fixed scanner unit 4, an arm protruding from the upper surface, a drive unit including a pinion gear and a drive motor that can rotate at the tip of the arm, and a moving rail 34 of the scanner suspension 31. The rack gear meshes with the pinion gear. As a result, the pinion gear attached to the fixed scanner unit 4 that meshes with the rack gear moves the fixed scanner unit 4 to the retracted position 42 as the drive unit rotates, or moves the fixed scanner unit 4 to the initial position 41. It can be moved.
Further, the structure is not limited to the rack gear and the pinion gear, but a wavy flat belt may be wound around the drive gear to move the fixed scanner unit 4 to the retreat position 42 or the like.
Further, a contact switch is provided at the rearmost end portion where the fixed scanner portion 4 moves to the retreat position 42, and the contact switch provided at the rearmost end portion is connected (turned ON), whereby the fixed scanner portion. The contact switch outputs a signal indicating that 4 is located at the retracted position 42 to the CPU 21. When the CPU 21 receives this signal, it outputs a command signal instructing the drive unit to stop the movement of the fixed scanner unit 4. .
In step S55, the CPU 21 outputs a command signal for moving the fixed scanner unit 4 to the drive unit, and mechanically moves the fixed scanner unit 4 to the retracted position 42 (step S55). After the fixed scanner unit 4 has been moved to the retracted position 42, the contact switch provided at the rearmost end outputs information to the CPU 21 that it has moved to the retracted position. Based on the information input from the contact switch, the CPU 21 deletes the “save” button of the display unit 2 with a touch panel.

Next, the flow of processing for controlling the CPU 21 to move (return) the fixed scanner unit 4 from the retracted position 42 to the initial position 41 will be described with reference to the flowchart of FIG. First, the processing from step S81 to step S82 is the same as the processing from step S61 to step S62 in FIG. Next, when the operator presses the “return” button (YES in step S83), the touch panel display unit 2 outputs to the CPU 21 information that the return button has been pressed. Based on the input information, the CPU 21 outputs an inquiry signal to the automatic change fishing ticket machine 7, and the signal received from the automatic change fishing ticket machine 7 is filled with coins and bills inside the automatic change fishing ticket machine 7. If the signal indicates that the problem has been resolved (eg, normal signal, error status value is 0), a command signal is issued to instruct the drive unit to move the fixed scanner unit 4 to the initial position. The scanner unit 4 is moved to the initial position (step S84). However, if the trouble such as coins or bills jamming inside the automatic change bill machine 7 has not been solved (for example, the abnormal signal, error status value is 1), the CPU 21 has not solved the error. Is output to the display unit 2 with a touch panel. In this case, the fixed scanner unit 4 is not moved to the initial position.
Next, the completion of the movement of the fixed scanner unit 4 to the initial position will be described. The photo sensor unit 22 outputs information that the fixed scanner unit 4 is present at the initial position to the CPU 21. The CPU 21 to which the information has been input determines that the fixed scanner unit 4 has moved to the initial position (movement completed).
In addition, the process shown below may be sufficient as the process of said determination. The fixed scanner unit 4 is provided with a contact switch at the foremost end of the initial position 41. When the contact switch provided at the foremost end is connected (turned on), the contact switch outputs a signal indicating that the fixed scanner unit 4 is located at the initial position 41 to the CPU 21. The CPU 21 to which the signal is input determines that the fixed scanner unit 4 has moved to the initial position 41.

  Next, based on the determination, the CPU 21 causes a current to flow through the electromagnetic solenoid 32 and lowers the sheet metal 33 (step S85).

  As described above, when the sheet metal 33 is lowered, even when the operator touches the fixed scanner unit 4 at the time of an accounting operation or a scanning operation, the fixed scanner unit 4 may not be moved carelessly backward. it can.

  In the present embodiment, the sheet metal 33 is moved up and down by the electromagnetic solenoid 32. However, the present invention is not limited to this, and an actuator that moves such as expansion and contraction or expansion and contraction is used as a mechanical mechanism. It may be moved up and down by an hydraulic / pneumatic mechanism or spring elasticity.

  In the present embodiment, the metal solenoid 32 moves up and down. However, the present invention is not limited thereto, and a stopper (for example, a rubber plate) made of a material having a high friction coefficient is sandwiched from both ends of the fixed scanner unit 4. The stopper may be separated from the fixed scanner unit 4 when it is held so as not to move and moved. Moreover, although the automatic change fishing bill machine 7 was illustrated in the present Example, it may not be automatic. Further, when a trouble such as money jam occurs in the change machine, a stopper such as a sheet metal of the scanner unit or a material having a high friction coefficient may be released without an instruction from the operator.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design etc. of the range which does not deviate from the summary of this invention are included.
