Yes.

  The racks 71 and 72 are arranged on the back case 44 side in the left-right direction corresponding to the movement ranges of the pinion gears 73 and 74 when the opening and closing doors 53a and 53b are opened and closed. The pinion gears 73 and 74 are engaged from the front side. The racks 71 and 72 are provided, for example, on the front side of the left and right ridges 69 and 70 projecting from the front side of the back wall plate 45 on the back case 44 side.

  In the center case 24 as described above, in the normal state, the movable effect means 43 is in a state where the open / close doors 53a and 53b are stopped at the left and right open positions and the entire display screen 30a is visible from the front side ( 4 and 6). For example, when a closing command for opening and closing doors 53a and 53b is output from the game control means (not shown) during the game operation, the motor 68 is closed by the effect control means (not shown) for controlling the movable effect means 43. A driving command in the direction is transmitted. Thereby, the motor 68 on the left opening / closing door 53a side rotates the pinion gear 67 in the clockwise direction when viewed from the front, and the motor 68 on the right opening / closing door 53b side rotates the pinion gear 67 in the counterclockwise direction when viewed from the front, for example. Then, the driving operation of the preset number of steps is started.

  When the driving operation of the motor 68 in the closing direction is started, the rack 65 meshing with the pinion gear 67 is moved, and the open / close doors 53a and 53b to which the racks 65 are fixed are closed. Start moving in the direction.

  When the open / close doors 53a and 53b move in the closing direction, the pinion gears 73 and 74 disposed on both the upper and lower ends of the open / close doors 53a and 53b rotate in the same direction on the racks 71 and 72, respectively. However, since the upper and lower pinion gears 73 and 74 are connected by the connecting rod 75, their rotational operations are exactly the same, and therefore the moving operations along the racks 71 and 72 are also exactly the same. Therefore, although the opening / closing doors 53a and 53b are transmitted only from the driving means 64 to the lower end side thereof, the upper end side is not delayed with respect to the opening / closing operation of the lower end side, and the opening / closing doors 53a and 53b are in a straight state. It can be moved to the closed position while maintaining it, and even if it stops at the closed position, for example, no gap remains on the upper end side (FIGS. 5 and 7).

  When the open / close doors 53a and 53b are moved from the closed position to the open position, each motor 68 may be driven in the reverse direction by a predetermined number of steps. Note that the operation delay of the upper end side of the open / close doors 53a, 53b with respect to the lower end side is exactly the same in the opening operation.

  As described above, the pachinko machine of this embodiment is engaged with the pair of racks 71 and 72 arranged in the left-right direction corresponding to the upper and lower ends of the open / close doors 53a and 53b, and the racks 71 and 72, respectively. A pair of upper and lower pinion gears 73 and 74, and a connecting rod 75 for interlocking the pair of pinion gears 73 and 74. The racks 71 and 72 are fixed to the back case 44 side, and the pinion gears 73 and 74 and the connecting rod Since 75 is mounted on the opening / closing doors 53a, 53b side, the left / right movements on both the upper and lower ends of the opening / closing doors 53a, 53b can be completely interlocked, and the driving force is raised and lowered with respect to the opening / closing doors 53a, 53b. In spite of transmission in an unbalanced state, the open / close doors 53a and 53b can be smoothly driven in the left-right direction without rattling.

  The drive mechanisms 55a and 55b are provided with a pair of left and right open / close doors 53a and 53b. The drive mechanisms 55a and 55b open the open and close doors 53a and 53b apart from each other in a closed position where the closed side edges 54a and 54b substantially contact each other. Although it is configured to open and close between the positions, the operation on the upper end side of the open / close doors 53a and 53b is not delayed with respect to the lower end side, so that no gap remains on the upper end side in the closed position. .

  The pinion gears 73 and 74 are arranged with their axes directed upward and downward, and the pinion gears 73 and 74 are fixed to both ends of a vertical connecting rod 75 that is rotatably supported on the doors 53a and 53b. Therefore, the rotation of the upper and lower pinion gears 73 and 74 can be interlocked with a very simple structure.

  8 and 9 illustrate the second embodiment of the present invention, in which the upper and lower pinion gears 73 and 74 and the connecting rod 75 are arranged on the back case 44 side, and the racks 71 and 72 are arranged on the open / close doors 53a and 53b side, respectively.

Racks 72 are provided on the upper surface side, and upper and lower pinion gears 73 and 74 mesh with the racks 71 and 72, respectively.

  The upper and lower pinion gears 73 and 74 are fixed to the front end side of the front and rear rotation shafts 73a and 74a. The rotation shafts 73a and 74a are, for example, bearings 78 provided on the back wall plate 45 of the back case 44. , 78 are rotatably held. Further, pulleys 79 and 80 are fixed to the rotary shafts 73a and 74a, for example, on the rear end side and on the rear side of the back wall plate 45, respectively, and a belt 81 is wound around the upper and lower pulleys 79 and 80. Yes. Other configurations are the same as those of the first and second embodiments.

  As described above, even if the upper and lower pinion gears 73 and 74 are arranged with their rotary shafts 73 a and 74 a facing forward and backward, and the upper and lower pinion gears 73 and 74 are interlocked by the belt 81, As in the embodiment, the driving force is transmitted to the open / close doors 53a, 53b in an unbalanced state, and the open / close doors 53a, 53b are smoothly driven in the left-right direction without rattling. Is possible.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to these each embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, as in the third embodiment, the upper and lower pinion gears 73 and 74 are arranged with their rotary shafts 73a and 74a facing forward and backward, and the rotations of the upper and lower pinion gears 73 and 74 are interlocked. Alternatively, the pinion gears 73 and 74 and the rotation interlocking means may be arranged on the opening / closing doors 53a and 53b side, and the racks 71 and 72 may be arranged on the base body side such as the back case 44, respectively.

  Further, the rotation interlocking means for interlocking the upper and lower pinion gears 73, 74 is optimal from among connecting rods, belts, gear trains, etc. depending on the direction and distance of the rotation shaft of the pinion gears 73, 74, the surrounding conditions, and the like. Just choose one. For example, a gear train or the like may be used as the rotation interlocking unit of the first and second embodiments, and the same applies to the case of the third embodiment.

  The movable bodies 53a and 53b are not limited to door-shaped ones, but can be any shape. Further, the structure of the guide mechanism and the drive means 64 for guiding the movable bodies 53a and 53b in the left-right direction is also arbitrary.

  For example, in the case of the first embodiment, the movable bodies (door main bodies) 53a and 53b are formed of a transparent or translucent light transmitting member and a shielding member that does not transmit light, and the connecting rod 75 and the like are arranged on the rear side of the shielding member.
