As shown in FIG. 7, the sliding piece 53 is slid right and left in the long hole 54 formed in the curtain plate piece 40b so that the knob 52 is exposed on the front surface of the front mounting plate 42b. The sliding piece 53 is movably mounted, and the sliding piece 53 is urged in the direction of the arrow by a small coiled spring 55 whose one end is locked to the back surface of the curtain plate piece 40b by a screw 55a. Therefore, when the sliding piece 53 is slid against the elasticity of the spring 55 while pressing the knob 52 with a fingertip, the hook-shaped acting portion 53a formed on the sliding piece 53 is brought into contact with the engaging groove. The pin 48 comes out of the engagement groove 50 by being pressed against the pin 48 in 50. When the fingertip is released from the knob 52, the sliding piece 53 is returned to its original position by the elasticity of the spring 55.

  The curtain plate pieces 40a, 40b are formed by inserting the support shafts 30a, 30b of the sliders 25a, 25b into bearings formed at both ends of the curtain plate pieces 40a, 40b, respectively. It is rotatably supported inside. Here, the winding springs 31a and 31b urge the respective curtain plate pieces 40a and 40b in a direction of projecting forward.

  Next, the configuration of the curtain lock mechanism 61 will be described with reference to FIGS. The tab lock mechanism 61 engages and disengages a hook-like piece 45 fixed to the back surface of the tab piece 40a with a lock 59 provided on the back plate 16, and the lock 59 moves forward and backward. A lock piece 57 is provided so as to be freely movable, and the lock piece 57 is urged by a spring in the lock so that a tip portion 58 formed in a wedge shape normally projects outward. A push button 56 serving as an unlocking portion is provided on the back plate 16 so as to be exposed on the back surface of the back plate 16. Therefore, when the hook-shaped piece 45 comes into contact with the wedge-shaped slope of the tip 58, the tip 58 of the lock piece 57 is temporarily inserted into the lock 59 against the elasticity of the spring in the lock 59. As shown in FIG. 14, the tabs 4 a, 4 b are locked in the non-extended state (closed state) by being retracted, returning by the elasticity of the spring and projecting. I am trying to. Further, when the push button 56 is pressed in this non-extended state, the distal end portion 58 retreats and the engagement with the hook-like piece 45 is released, so that the curtain plates 4a and 4b move forward. Overhang is possible. Then, the sliders 25a and 25b approach each other by the urging of the urging members 33a and 33b, thereby bending the curtain plates 4a and 4b into a V-shape and projecting forward. In this way, the push button 56, which is the unlocking portion of the curtain lock mechanism 61, is provided so as not to be exposed on the front side of the gaming machine, and cannot be operated by the player at all.

  As described above, when the gaming machine equipped with the self-standing device according to the present invention is temporarily placed in an upright state on the floor of the gaming hall to be installed in the gaming hall, for example, the push button 56 is pressed from the back side of the gaming machine. As a result, the curtain plates 4a and 4b are bent in a V-shape at once, and project forward as shown in FIG. For this reason, the gaming machine is in a stable standing state, and a fall to the front is prevented. When the curtain plates 4a and 4b are bent as described above, the pin 48 at the distal end of the connecting rod 46 is pulled by the spring 51, slides in the guide groove 49, enters the engaging groove 50 and is locked. Therefore, the connecting rod 46 is bridged between the curtain plate pieces 40a, 40b to form a triangular trust. For this reason, the strength is increased, and even a heavy gaming machine can be reliably prevented from falling. Moreover, since the curtain plates 4a and 4b are urged by the urging members 33a and 33b, they can be pushed forward with only one touch of the push button 56, so that the operation is simplified.

In order to return the curtain plates 4a and 4b that have been protruded forward, the knob 48 is slid in the direction of the guide groove 4 while pressing the knob 52 with a fingertip. Return to 49. After that, since the pin 48 can slide freely in the guide groove 49, if the curtain plates 4a and 4b are pressed by hand, the curtain plates 4a and 4b extend straight as before and the curtains 4a and 4b extend straight. It is stored between the plate-side front cover members 17a and 17b and is in a non-extended state (closed state). At this time, the hook-shaped piece 45 is engaged with the lock piece 57, so that this non-extended state is maintained. Therefore, in a state where the gaming machine is installed on an island in a game arcade, it is difficult for a player to see that such a self-supporting device exists when viewed from the front of the gaming machine, and there is no risk of impairing the appearance. The knob 52 remains exposed on the surface of the curtain plate 4b. However, even if the knob 52 is operated by the player, the sliding piece 53 only moves left and right, so there is no problem. Absent.
Further, a common pinion 37 is meshed with the rack teeth 35a, 35b, and the sliders 25a, 25b are always slid in the opposite direction in the horizontal direction by the same distance, so that the urging force of the urging members 33a, 33b is reduced. By making adjustments, the curtain plates 4a and 4b can be gently extended so that an accident such that the curtain plates 4a and 4b suddenly jump out and collide with a worker is prevented.

  As described above, in the gaming machine provided with the self-standing device according to the present invention, since the curtain plate projects forward, the gaming machine can be provided in a conventional dead space without impairing the aesthetic appearance of the gaming machine. In addition, by operating from the back side of the gaming machine, the curtain plate projects forward with one touch, so that the operation is simple and sufficient strength can be obtained in the extended state. Therefore, by providing the self-supporting device, even a heavy game machine can be reliably prevented from falling.
