The process progresses through the stages of matching the pictures of ``grapes'' and ``grapes'' accurately.

In this way, for young children who are unable to read and do not have a solid relationship between objects and words, it is possible to do this by hand using cards with pictures of apples, grapes, etc. There is a need for a learning device that has functions such as responding to this input and uttering words that correspond to the pictures drawn on the card, or notifying whether the correspondence is correct or incorrect.

(Means for Solving the Problems) In order to solve the above problems, the learning device of the present invention includes teaching materials with different barcodes displayed depending on the learning program, and a barcode reading device provided on the learning device main body. , a signal converting means for converting a barcode signal read by a barcode reading device into an input signal of a learning device.

In this case, the teaching material with the barcode displayed is composed of a plurality of insertable media that can be attached to and removed from the main body of the learning device, and the barcode reading part is fixed at a position facing the surface of the inserted media on which the barcode is formed. It is preferable to provide it in the main body of the learning device.

Further, it is preferable that the power supply unit of the main body of the learning device has a built-in DC power supply and has a structure to which an AC adapter can be connected, and that the CPU is composed of a C-MOS type element.

(Function) According to the configuration of the learning device of the present invention, the barcode of the teaching material on which the barcode is displayed is read by the barcode reading device provided on the learning device main body, and the barcode reading device outputs a barcode signal. be done.

Then, this barcode signal is converted into an input signal of the learning device by the signal converting means, and the learning device responds to this signal input to proceed with learning.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a system configuration diagram showing an example of the learning device of the present invention.

In this learning device 1, C and PI 3 are connected to a power supply unit 2, an input unit 4, a memory unit 5 for learning programs and audio data, and a speech synthesis unit 6 are connected to the CPLI 3, and a speaker 7 is connected to the speech synthesis unit 6. Learning device body 8 consisting of a speaker connected to
The barcode card 9 is detachably attached to the input unit 4, and the IC memory card 10 is detachably attached to the memory unit 5, and is configured as an audio output type learning device. .

Here, the learning device of the present invention changes the memory unit 5 to a memory unit for the learning program and image data or a memory unit for the learning program, audio data, and image data, and replaces the voice synthesis unit 6 and the speaker 7 with the image data. It is also possible to construct an image output type learning device or an audio/image output type learning device that outputs an image along with audio by changing at least one of a playback block, a display, and a printer, or by adding these.

Among these, the power supply unit 2 in the learning device main body 8 is A
C adapter (6■) and dry battery (SUM-2X4) 2
It is configured to use a power source, and by inserting the AC adapter connector into the AC adapter jack provided on the learning device main body 8, it is possible to switch from the dry battery built in the learning device main body 8 to the AC adapter. . In addition, the power from the AC adapter and dry battery passes through the power filter provided in the power supply unit 2, is stabilized by the three-terminal regulator provided in the power supply unit 2, and is supplied to the CPL 13, etc. There is.

Incidentally, the power supply unit 2 may be a power supply unit dedicated to an AC adapter, which includes a part of the AC adapter, or a power supply unit dedicated to a DC power supply such as a dry battery.

As described above, when the power source is a dual power source system of an AC adapter and a dry battery, it is preferable to use a C-MOS type compatible with the 280 with a clock frequency of 4 Mz, for example, for the CPU 3.

In addition, a slot 11 is provided in the input unit 4 from the outside toward the inside of the input unit 4 so that the barcode cart 9 can be easily attached to and detached from the learning device main body 8.
Furthermore, a keyboard jack 12 for connecting a keyboard is provided.

However, in a learning device with a simple structure that performs simple learning without a complicated learning program, the keyboard jack 12 is omitted, and the learner's manual input, such as answering, is done only with the barcode card 9. By this,
It is possible to provide a learning device with a simple and inexpensive structure that corresponds to the complexity of the learning program.

Here, the barcode card 9 includes a function card 9 for selecting and instructing a predetermined learning program (for example, questions).
There are two types of work cards: a and a work card 9b on which selective answers to this question are displayed (for example, in a study for young children to memorize the names of fruits, pictures of multiple types of fruits that are taken up in this study) are displayed. be. And, on the back side where each content is not displayed, there is a barcode corresponding to each content, which will be described later when inserted into the barcode card 9 insertion slot 11! The barcode card 9 is displayed in the longitudinal direction of insertion, starting from the insertion side tip of the barcode card 9 so as to be read by the barcode reading portion 13a of the scraping device 13.

On the other hand, as shown in FIG. 2, the slot 11 for inserting the barcode card 9 has a barcode reading device 13 fixedly installed on the inner surface of the groove with its barcode reading portion 13a exposed. 9 is inserted correctly, the barcode of this barcode card 9 is read by the barcode reading section 13a of the barcode reading device 13, and selective answers to the questions in the predetermined learning program are manually entered into the learning device main body 8. It looks like this.

By the way, the structure of this part is, for example, instead of the barcode card 9, an answer similar to that of this barcode card 9 and a barcode corresponding to this are passed, and a bound teaching material printed in an appropriate layout is used, and the barcode is printed. The reading device 13 has a structure in which the barcode reading portion 13a of the barcode reading device 13 scans the barcode of this teaching material and the answer is manually inputted to the learning device main body 8, that is, the barcode reading portion 13a of the barcode reading device 13 is movable. It may also have a structure connected to the main body 8.

The memory unit 5 also has an operating system (operating system) built into the learning device body 8, which will be explained in detail later.
3) Temporarily stores the program-only memory 58 containing the learning program data part, the audio data-only memory 5b containing the audio data part, and the learning program data from the program-only memory 58 read by input. It is composed of a work memory 50 for reading data, and an external IC memory card 10 (a third
(see figure).

The learning device main body 8 is provided with a slot 14 for a pocket-shaped IC memory card 10, and by inserting the IC memory cart 10 into the slot 14 and operating the learning device main body 8, the input unit 4 performs the manual operation. , the CPU 3 operates to select the learning program stored in the IC memory card 10 or the program dedicated memory 5a and the audio data stored in the audio data dedicated memory 5b or the IC memory card 10, and according to the input. The learning operation and the output of audio data from the IC memory card 10 or the audio data dedicated memory 5b are performed.

In the above memory configuration, if the learning program is simple or short, the program dedicated memory 5a
Either the audio data dedicated memory 5b or the IC memory card 10 can constitute a program memory and an audio memory.

In addition, if the learning program and therefore O3 are complex, such as requiring complicated learning operations, 05-R for this purpose may be necessary.
Either the OM is built into the learning device body 8 or the OS
A ROM' slot may be provided and the 03-ROM may be detachably inserted into the 05-R, 0M slot.

Note that this IC memory card 10 may be one in which a corresponding memory medium is fixedly built into the memory unit 5. Furthermore, in some cases, the IC memory card 10 may be replaced with another memory medium such as a cassette-type magnetic tape.

FIG. 3 is a block diagram of the learning device 1. As shown in FIG.

In this learning device 1, the power source 2a is turned on to the learning device main body 8, and an IC containing a desired learning program to be learned is connected.
The function card 9a is installed in the slot 11 for inserting the barcode card 9, with or without installing the memory cart 10 in the slot 14.

As a result, the IC memory card 10 is
(For example, 512 bytes and maximum 1M byte mask RO
A predetermined learning program is specified from the learning program stored in M) or the program-only memory (for example, a 16-byte EP-ROM) 5a, and learning operation parts such as questions are read out and stored in the work memory. 50 is temporarily stored.

Next, the bank selector 15 selects the corresponding IC memory card 1o or audio data dedicated memory (
At 512, the data is switched to the audio data portion of the byte mask ROM 5b, and a predetermined learning operation is started according to a predetermined learning program.

That is, since the learning device 1 uses a memory of 64 bytes or more, it has a memory configuration using a bank switching method. Therefore, the address space of the CPU 3 is divided into, for example, four parts, two of which are One is assigned as a fixed address to the program-only memory 58 and the work memory 50, respectively, and the remaining two are allocated to the memory of the IC memory card 10 and the audio data-only memory 5.
When the CPU 3 brings data from each memory, the data from each memory can be switched by the bank selector 15.

In this way, when the function cart 9a is installed in the slot 11 for inserting the barcode card 9, the first question of the predetermined learning program (for example, What is this?) is asked.
The audio data of the question) is sequentially read out by the CPU 3 from the IC memory card 10 or the audio data dedicated memory (Pitonomask ROM 512) at a predetermined address.

This audio data is then transferred to the ADP of the audio synthesis unit 6.
ADPC through CM interface (1/F) 6a
This ADPCM data is converted to ADPCM data.
It is synthesized in M synthesis 6b.

Next, the AMP is passed through an LPF (low-pass filter) 6c1, for example, a 4th-order ldb ripple Tievishev type active filter with a cutoff frequency of 3.5kHz.
(Power amplification section) 6d amplifies the question, and the question is output as voice from the speaker 7.

After that, the answer to this question (e.g. "apple")
A work card 9b selected from among a plurality of fruits (for example, pictures of a plurality of fruits including "apples" and corresponding bar codes are displayed) is inserted into the slot 12.

Then, if the work card 9b is inserted correctly, the LED 4a in the input unit 4 does not light up and the barcode sensor 4b operates, and the barcode on the workcard 9b is read by the barcode reading device 13 described above. The answer to the question is read by part 13a, and the answer to the question is sent to the reader interface (I/F
) 4c to the learning device main body 8. Conversely, if the work card 9b is not inserted correctly, the LED 4a lights up for the time set by the timer 4d.

In this way, the answer to the question is provided to the learning device main body 8.
When manually operated, CPU3 selects bank selector 15.
The answer is compared with the answer stored at a predetermined address. Next, the voice data according to the correctness or wrongness of the answer is read out from a predetermined address in the memory card 10 or voice data-only memory (512-byte mask ROM) 5b, and the same process as in the case of the previous question is briefly performed to answer the question. A voice reporting the correctness is output from the speaker 7.

Learning progresses through repetition of such questions and answers.

In addition, if the learning becomes advanced and the learning program becomes complicated, a keyboard with special keys 4e can be inserted into the keyboard jack 12 shown in Figure 1, and the key interface (I/F) 4f can be passed through the keyboard. Use manual labor to repeat the same questions and answers as above.

In this case, for example, an overlay sheet is used that has keys displayed in a pattern corresponding to each learning program or predetermined learning operations (questions, answers, etc.) within the learning program, and this overlay sheet is placed on the key plate of the keyboard. A special key 4e can be configured by placing the key 4e. In addition, an input method can be adopted in which the manual input using the special key 4e is performed by scanning all the keys three times, and when the input keys match twice or more, it is determined that the input key is normal and the manual input is performed. This manual operation method increases the reliability of manual input since it is determined that it is an error if all three key codes are different or if multiple keys are pressed.

In addition, the keyboard in this case is, for example, A in Fig. 4.
1...100 normal keys indicated by IA and B1...
-Special key 4e indicated by CA.

In other words, it consists of 20 function keys, and on top of this, an appropriate overlay sheet is selected from a plurality of overlay sheets with different input displays for each learning stage, and from this overlay sheet, the plurality of function keys are selected and laid down. Species key, e.g. B1, B6 and C
It is also possible to select and press one of the three keys numbered 3 (this varies depending on the overlay sheet and is specified on the overlay sheet) to designate a particular learning program corresponding to this key combination.

(Effects of the Invention) As is clear from the above explanation, the learning device of the present invention has the following effects:
The human power means includes a barcode reading device provided on the main body of the learning device, and a signal converting device (for example, the reader I/
F 4 c )' and teaching materials (
For example, since the barcode is displayed on the barcode card 9) in the above embodiment, even young children can easily answer the question by having the barcode displayed on the teaching material read by the barcode reading device installed in the main body of the learning device. It is possible to proceed with learning by doing the same amount of human effort by one person.

Here, the teaching materials with barcodes displayed are inserted into a plurality of removable insertion media into the main body of the learning device, and the barcode reading portion of the barcode reading device is inserted into the insertion slot of the main body of the learning device facing the insertion direction of the insertion media. If fixed,
Compared to reading barcodes by scanning a barcode reading device, operability for young children can be improved.
In addition, since there is no need to provide a barcode reader separate from the learning device itself with wiring connected to the learning device so that it can be scanned, the learning device itself can have a compact and simple structure, making it easy for young children to operate. This also reduces malfunctions. .

In addition, the power supply unit of the learning device has a structure that allows for a built-in DC power supply and an AC adapter connection, and the CPU
If it is constructed from C-MOS type elements, a learning device suitable for carrying can be provided.

Furthermore, when performing advanced learning, connect a keyboard to the input unit that allows you to select and press multiple types of keys to specify a specific learning program that corresponds to the key combination, and place an overlay sheet on this keyboard. You can also select a learning program using the keypad from this overlay sheet.
