 For example, a pachinko game machine is provided with a display device in parallel to display the state of the game machine such as "big hit" during the game. Such a display device is usually provided with a display board, which is placed upright on the front surface in a specific state of the game machine so that the display can be seen by others. What is done is that the clerk manually rotates the display plate to stand upright, uses an electric motor and a worm gear, or automatically rotates the display plate upright by using an electromagnetic actuator. Etc.

By the way, in the case where the display plate is manually erected upright, the responsiveness is insufficient, whereas in the case where the electric motor and the worm gear that automatically erect the display plate are used, the display plate can freely rotate due to the engagement of the worm gear. Therefore, if the display plate is forcibly rotated due to mischief or the like, the display plate may be broken or the worm gear may be damaged. In addition, it emits an unpleasant noise and is not so satisfactory either.

Further, in this type of display device, it is preferable that, along with the demand for aesthetics, there is no gap or the like that allows dust, cigarettes, etc. to be inserted into the case by mischief.

The present invention has been made in view of the above points, and an object thereof is to prevent breakage or damage even if the display plate is forcibly rotated by mischief, etc. An object of the present invention is to provide a display device that can eliminate the problem.

Another object of the present invention is to provide a display device which is aesthetically pleasing and in which unnecessary gaps and the like do not occur at the rotating position of the display plate.

[0007]

[Means for Solving the Problems]

 According to the present invention, the objects are a case, an electric motor mounted in the case, a display plate rotatably attached to the case via a rotation shaft, and a rotation of an output rotation shaft of the electric motor. Is transmitted to the rotation shaft to rotate the display plate, the display device is provided with a gear mechanism arranged between the rotation shaft and the output rotation shaft of the electric motor.

In order to achieve the above object, in the present invention, the case has a front wall portion having a recess, and the front wall portion defines a front lateral wall portion defining one edge of the recess. And a front bottom wall that defines the bottom of the recess, and a gap that connects the inside and outside of the case is formed between one edge of the front lateral wall and one edge of the front bottom wall. The display plate is located in a recess in the front wall of the case and extends almost parallel to the front bottom wall, and one end of the display plate extends inside the case with a gap. The final gear of the gear mechanism is fixed to the rotation shaft, and the rotation shaft is integrally formed on the back surface of the display plate. When the display plate is installed in a position that extends almost parallel to the front bottom wall, a gap is closed by one end of the display plate. When the display plate is chained and arranged at a position that extends substantially perpendicular to the front bottom wall, the gap is closed by one end of the display plate and the protrusion for mounting the rotation shaft. The above-mentioned display device is provided in which the projection for attaching the shaft is provided on the back surface of the display plate.

The projection may be in any form as long as it achieves the above-mentioned function, but in a preferred example, it is formed of a quadrangular prism.

The case 2 has a front wall portion 12 in which a recess 11 is formed, and the front wall portion 12 includes a front lateral wall portion 14 that defines an edge 13 of the recess 11 and the recess 11. It has a front bottom wall portion 15 that defines the bottom and another front lateral wall portion 17 that defines the other edge 16 of the recess 11, and one edge 13 of the front lateral wall portion 14 and one of the front bottom wall portion 15 are provided. A gap 19 is formed between the edge 18 and the inside of the case 2 to communicate with the outside of the case 2. The recess 11 is formed so that its depth D is substantially the same as the thickness T of the display plate 5.

The electric motor 3 is a direct current electric motor, and is operated by a command from a controller of a pachinko game machine, for example.

The display plate 5 is disposed at the recess 11 of the front wall 12 of the case 2 by the operation of the electric motor 3 and extends substantially parallel to the front bottom wall 15 (see FIG. 3). Position) and a position (a position shown in FIGS. 1 and 2) in which one end portion 21 extends inside the case 2 through the gap 19 and extends substantially orthogonally to the front bottom wall portion 15 (A and B). The final gear 22 of the gear mechanism 7 is fixed to the rotating shaft 4 which is rotatably supported by the case 2. On the front surface 23 and the back surface 24 of the display board 5, respectively, a display showing a specific playing state of the pachinko game machine, for example, a "big hit" or the like is printed or is provided on an electro-optical element. The back surface 24 of the display plate 5 is integrally provided with a protrusion 25 formed of a quadrangular prism body for mounting the rotating shaft. When the display plate 5 is arranged at a position where the display plate 5 extends substantially parallel to the front bottom wall portion 15, the projection 19 is closed by the one end 21 of the display plate 5, and the display plate 5 is closed. The gap 19 is provided so as to be closed by the one end portion 21 of the display plate 5 and the projection 25 for mounting the rotating shaft when it is arranged at a position extending substantially directly to 15.
