When the positioning projection 65 is provided in the security structure 45, the positioning hole 66 is provided in the front door 5, and when the positioning projection 65 is provided in the front door 5, the positioning hole 66 is provided in the security structure 45.

  Further, when the opening of the front door 5 in the opening direction X1 proceeds, as shown in FIG. 6, the door stopper 44 collides with the frame stopper 40, and the front door 5 opens to the front side of the movable frame 3 at the maximum opening angle θ1. It is done. When the front door 5 stops at the position where the movable frame stopper 40 and the door stopper 44 collide with each other, the return prevention stopper 46 is separated from the movable frame stopper 40, and the return prevention stopper 46 and the movable frame stopper 40 are A gap 62 is formed in which the front door 5 is movable in the direction of the closing direction X2. Further, a person who opens the front door 5 in a range from when the return prevention stopper 46 exceeds the frame stopper 40 in the opening direction X1 to when the front door 5 is opened to the front side of the movable frame 3 at the maximum opening angle θ1. By releasing the hand from the front door 5, the operating force for opening by the person from the front door 5 is removed, and when the front door 5 returns to the closing direction X2, as shown in FIG. 7, the return prevention stopper 46 is a frame stopper. Collide with 40.

  In FIG. 7, when the front door 5 moves in the closing direction X <b> 2 from the position of the maximum opening angle θ <b> 1 indicated by the phantom line to the position indicated by the solid line, the edge portion 60 of the return prevention stopper 46 is the side surface of the upper end portion of the frame stopper 40. Collide with and touch. Thus, if the person does not move the front door 5 in the closing direction X2 with a force larger than the resistance accompanying the contact between the return prevention stopper 46 and the frame stopper 40, the front door 5 is no longer in the direction of the movable frame 3. Will never return. When the front door 5 is stationary at the position where the edge 60 of the return prevention stopper 46 collides with the side surface of the upper end of the frame stopper 40, the opening angle θ2 of the stationary front door 5 does not include 90 degrees. It is set in the range of more than degrees and less than the maximum opening angle. 6 and 7, the alternate long and short dash line L <b> 5 indicates the front surface of the movable frame 3, and the alternate long and short dash line L <b> 6 indicates the back surface of the front door 5. Therefore, the maximum opening angle θ1 and the opening angle θ2 of the front door 5 are the movable frame 3 when the front door 5 is laterally opened to the front side of the movable frame 3 around the frame hinge 10 and the door hinge 12. Is the included angle between the front surface of the front door 5 and the back surface of the front door 5. A gaming machine installation structure of the gaming machine frame 1 in a range from when the return prevention stopper 46 exceeds the frame stopper 40 in the opening direction X1 until the front door 5 is opened to the front side of the movable frame 3 at the maximum opening angle θ1. Even if the front door 5 naturally moves in the closing direction X2 due to its own inclination angle, the edge 60 of the return prevention stopper 46 and the side surface of the upper end of the frame stopper 40 collide with each other. The front door 5 opened at the maximum opening angle θ1 naturally closes in the direction of the movable frame 3 and does not come into contact with the movable frame 3, thereby preventing the front door 5 from returning.

  According to the best mode, since the anti-return stopper 46 is provided on the security structure 45, a protrusion as the anti-return stopper 46 is provided on the security structure 45 so that the return prevention stopper 46 collides with the frame stopper 40. Therefore, there is an advantage that the structure as a front door return prevention device that can keep the state where the front door 5 of the gaming machine frame 1 is opened to the maximum is easy. When the front door 5 moves from the maximum opening angle θ1 in the closing direction X2 and the frame stopper 40 and the return prevention stopper 46 collide with each other, the opening angle of the front door 5 does not include 90 degrees and is the maximum at 90 degrees or more. A return prevention stopper 46 is provided at a position that is less than the opening angle θ1. That is, when the front door 5 is stationary at the position where the edge 60 of the return prevention stopper 46 collides with the side surface of the upper end of the frame stopper 40, the opening angle θ2 of the stationary front door 5 does not include 90 degrees. Since the front opening of the gaming machine frame 1 is located behind the lower front surface, the front of the gaming machine frame 1 is several degrees from the vertical plane. Even if the gaming machine frame 1 is installed in the gaming machine installation structure so as to exhibit an inclination angle, the weight of the front door 5 is reduced from acting so as to close the front door 5 in the closing direction X2, and the front door is reduced. There is an advantage that the return of 5 can be prevented appropriately. When the frame stopper 40 and the door stopper 44 collide with each other and the front door 5 stops at the maximum opening angle θ1, the frame stopper 40 and the return prevention stopper 46 are separated from each other, and the frame stopper 40 and the return prevention stopper 46 are separated from each other. Since a gap 62 shown in FIG. 6 is formed between the front door 5 and the front door 5 in the closing direction, the frame stopper 40 and the return prevention stopper 46 collide with each other as shown in FIG. When the person closes the front door 5 in the state where the return is prevented, the return prevention stopper 46 is attached with a run-up by closing the front door 5 after returning the front door 5 in the opening direction X1. There is an advantage that the frame stopper 40 can be smoothly crossed in the closing direction X2. In addition, since the gap 62 exists, the frame stopper 40 is moved to the gap 62 between the door stopper 44 and the return prevention stopper 46 by opening the front door 5 from the closed state to the movable frame 3 to the maximum opening angle θ1. Since it is reliably taken in, there is an advantage that the return of the front door 5 can be prevented appropriately. The anti-return stopper 46 may be formed separately from the existing security structure 45 and the anti-return stopper 46 formed separately may be attached to the existing security structure 45, but the return prevention stopper 46 is integrated with the security structure 45. Since it is formed, there is an advantage that the return prevention stopper 46 is also fixed to the front door 5 by fixing the security structure 45 to the front door 5. Since the return prevention stopper 46 is formed integrally with the security structure 45 from the same material, there is an advantage that the return prevention stopper 46 is firmly coupled to the security structure 45.
