The bar light source 176 is turned on to illuminate the outer peripheral surface of the display bodies 15 to 15 ″. Irradiation light from the rod-shaped light source 176 is reflected by the reflecting plate 178 made of white synthetic resin, and is effectively directed toward the display bodies 15 to 15 ″.

  Next, the player operates the gaming apparatus to rotate the display bodies 15 to 15 ″. By this operation, the player monitors the symbol mark changing at high speed from the fluoroscopic unit 111, and stops one of them. A so-called eye-pushing operation is performed to stop the rotation of the display bodies 15 to 15 ″. Hereinafter, the rotation operation of the other display bodies 15 to 15 ″ is stopped in order, and the game can be enjoyed by operating with the goal of displaying a desired symbol mark on the fluoroscopic unit 111.

  In the operation of such a gaming apparatus, a large amount of dust is generated when the game coin moves, but the cover 17 prevents it from adhering to the back surface of the liquid crystal module 11A. However, since there is a gap between the frame 14 and the cover 17, there are many cases where dust enters the inside of the cover 17 through this gap. Since the light source 122 that generates heat and the driving circuit board 13 exist in the cover 17, an upward air flow is generated in the cover 17, and a relatively large amount of dust enters from below. The intruding dust moves toward the center of the space 172 so as to slide on the inner surface of the cover 17 made of synthetic resin and having a smooth surface. However, the intruding dust is stagnated by the movement direction of the raised portion 175 being greatly bent. Of course, the dust also enters the space 172 from above and from the side, but the entered dust also stays at the raised portion 175.

  In addition, since dust generated by the movement of game coins and prize balls is a lot of metal powder, there is a possibility that the dust adheres to the drive circuit board 13 to cause an electrical failure such as a wiring short. Occurrence of such a failure can be prevented by preventing the intrusion of dust.

  The gap between the frame 14 and the cover 17 is necessary for dissipating the heat generated from the internal light source 122 and the drive circuit board 13 by convection with the outside air. Therefore, it cannot be completely sealed only for the purpose of dust prevention.

  Therefore, if the elastic material layer 174 is interposed between the light guide plate 121 and the entire periphery of the window portion 171, the window portion 171 is isolated from the space portion 172, so that there is dust that has passed through the raised portion 175. However, it does not reach the inner surface of the window portion 171.

  Therefore, in the above-described embodiment of the present invention, since the entire back surface of the liquid crystal module 11A is directly covered by the box-shaped cover 17, dust enters the space formed by the liquid crystal module 11A and the cover 17. Therefore, it is possible to prevent the dust from adhering to the back surface of the liquid crystal display panel 17 and the inner surface of the cover 17 to contaminate the surfaces of the see-through portion 111 and the window portion 171 and to deteriorate the quality. On the other hand, since the portion corresponding to the see-through portion 111 of the liquid crystal module 11A of the cover 17 is the window portion 171 made of a transparent member, the rear display bodies 15 to 15 ″ when the see-through portion 111 is made transparent are used as the liquid crystal module. It can be seen reliably from the front of 11A.

  Dirt on the front surface of the liquid crystal module 11A can be easily cleaned. Further, the surfaces on the display bodies 15 to 15 ″ side of the window portion 171 of the cover 17 can be cleaned relatively easily by removing the display bodies 15 to 15 ″. However, it is difficult to remove the dirt on the opposing surfaces of the liquid crystal module 11A and the window portion 172. Therefore, the quality of the transparent liquid crystal module, that is, the transparent liquid crystal display device 10 is constantly improved by eliminating dust entering the liquid crystal module 11A. To keep it high.

  Moreover, since the cover 17 is formed in a box shape and integrated by fitting the liquid crystal module 11A therein, the back surface of the liquid crystal module 11A can be easily covered entirely.

  In the embodiment of the present invention described above, the case where the see-through type liquid crystal display device of the present invention is applied to a gaming device has been described. However, the present invention is not limited to this, and various electronic devices having a display function are described. Of course, it can be applied to the above.

  For example, an actual object (juice, cigarette, etc.) is placed behind the fluoroscopic LCD module to convey a three-dimensional effect and texture that cannot be expressed with a simple image such as a vending machine or an in-vehicle meter. The type liquid crystal module is effective as a liquid crystal display device for displaying effects and explanations for making them more prominent.

  In the above-described embodiment of the present invention, the see-through unit 111 is provided at the center of the liquid crystal display panel 11, but may be provided at a position other than the center as necessary, and a plurality of the parts may be provided. It may be variously changed.

  Furthermore, in the embodiment of the present invention described above, the cover 17 is formed in a box shape as a whole, but the shape may be a flat plate shape.

  Although the illumination of the display body 15 by the rod-shaped light source 176 has been described above, the light source is not limited to the rod shape, and may be a point light source such as one or more light emitting diodes. The light source does not necessarily have to be provided on both the upper and lower sides of the window, and may be only on one side.

  In the above-described embodiment of the present invention, the transparent liquid crystal display panel 11 is a so-called transmissive liquid crystal panel that performs display using the backlight 12, but the so-called reflective liquid crystal panel that does not use the backlight 12. A liquid crystal panel may be used. In this case, outside the see-through portion of the liquid crystal display panel, for example, an external light reflecting means for reflecting outside light is provided by forming the pixel electrode with Al or the like, and the see-through portion is made of a transparent electrode material such as ITO. However, it may be formed so that light from the back side of the liquid crystal display panel passes.

  The embodiments of the present invention have been described above with reference to the drawings. However, what has been described above exemplifies an example for embodying the technical idea of the present invention, and is not intended to specify the present invention in this embodiment, and does not depart from the gist thereof. Various changes can be made in the scope, and the present invention can be applied equally to the modifications included in the claims.
