Abutted. Then, the door hook 56 in which the claw portion 56 b is in contact with the engagement piece 74 rotates in the Q direction against the bias of the coil spring 76. When the contact between the claw portion 56 b and the engagement piece 74 is released, the door hook 56 is rotated in the R direction by the restoring force of the coil spring 76. Thereby, the door hook 56 is locked to the engagement piece 74. Since the door hook 56 is not connected to the slide plate 58, the slide plate 58 is not slid even if the door hook 56 is rotated. Thereby, the main body member 11 and the front door 12 are locked.

  When unlocking the main body member 11 and the fixed frame 15, the unlock key 41 is inserted into the cylinder 40 and then the unlock key 41 is rotated in the B direction. By rotating the unlocking key 41 in the B direction, the transmission member 61 rotates, and the pressing piece 61b of the transmission member 61 presses the pressed piece 58h of the slide plate 58. In response to this pressing, the slide plate 58 slides in the D direction. As described above, since the other end 60b of the connecting rod 60 is located on the lower end side of the long hole 58d of the slide plate 58, when the slide plate 58 moves, the other end 60b of the connecting rod 60 becomes the lower end of the long hole 58d. The connecting rod 60 is moved in the H direction by being pressed by the inner wall surface on the side. On the other hand, the other end 59b of the connecting rod 59 is positioned on the upper end side of the long hole 58c, so that the connecting rod 59 does not move when the slide plate 58 slides in the D direction.

  When the connecting rod 60 moves in the H direction as the slide plate 58 moves in the D direction, one end 60 a of the connecting rod 60 presses the inner wall surface of the elongated hole 57 c of the frame hook 57. As a result, the frame hook 57 rotates in the F direction, and the engagement between the frame hook 57 and the engagement piece 81 provided on the fixed frame 15 is released.

  In the process of sliding the slide plate 58 in the D direction, the pressing piece 58 i provided at the lower end of the slide plate 58 presses the hook piece 101 of the hook lever 95. As shown in FIG. 12, the hook lever 95 is rotated in the S direction in response to the pressing. When the hook lever 95 rotates in the S direction, the holding stopper 100c of the hook lever 95 retracts from the rotation locus of the protruding piece 110b of the lock lever 96. Since the coil spring 97 is assembled to the hook lever 95 and the lock lever 96, when the hook lever 95 is rotated in the S direction, the lock lever 96 is biased by the coil spring 97 and is rotated in the T direction.

  When the lock lever 96 rotates in the T direction, the distance between the holding groove 110 c of the lock lever 96 and the receiving groove 64 d of the holding member 64 becomes smaller than the diameter of the engagement pin 120. Therefore, the engagement pin 120 is detached from the holding groove 110c. Since the engagement pin 120 is held by the fixed frame 15, the lock lever 96 is pressed by the engagement pin 120 in this process, and the main body member 11 is pushed out from the fixed frame 15. Then, when the lock lever 96 comes into contact with the stopper 64e of the holding member 64, the rotation of the lock lever 96 is stopped. When the lock lever 96 is stopped, the protruding piece 110b of the lock lever 96 is engaged with the receiving stopper 100b, and the lock lever 96 is held in a standby state. Thereby, locking with the main body member 11 and the fixed frame 15 is cancelled | released, and the main body member 11 can be rotated centering | focusing on the rotating shaft Z1.

  When unlocking the front door 12 and the body member 11, the unlock key 41 is rotated in the A direction after the unlock key 41 is inserted into the cylinder 40. By rotating the unlocking key 41 in the A direction, the transmission member 61 rotates, and the pressing piece 61 a of the transmission member 61 presses the pressed piece 58 h of the slide plate 58. In response to this pressing, the slide plate 58 slides in the C direction. Since the other end 59b of the connecting rod 59 is positioned on the upper end side of the long hole 58c of the slide plate 58, when the slide plate 58 moves in the C direction, the other end 59b of the connecting rod 59 is on the upper end side of the long hole 58c. The connecting rod 59 is pushed in the side direction and moved in the O direction. By this movement, one end 59 a of the connecting rod 59 presses the inner wall surface of the long hole 55 c of the door hook 55. Accordingly, the door hook 55 rotates in the M direction, and the engagement between the door hook 55 and the engagement piece 72 provided on the front door 12 is released. Since the other end 60b of the connecting rod 60 is positioned on the lower end side of the long hole 58d of the slide plate 58, the connecting rod 60 does not move even if the slide plate 58 moves.

  When the slide plate 58 slides in the C direction, the pressing piece 58e of the slide plate 58 presses the end of the door hook 56 opposite to the claw portion 56b, so that the door hook 56 rotates in the Q direction, The lock between the door hook 56 and the engagement piece 75 provided on the front door 12 is released, and the front door 12 is pushed out by a biasing means (not shown). Thereby, locking of the front door 12 and the main body member 11 is cancelled | released.

  When such a pachinko machine 10 is installed in the game hall, the game is executed by the player at the same time as the game hall is opened. However, some players do not use the unlock key 41 and do not use the wire. Is inserted through a gap generated between the pachinko machine 10 and the island of the game hall, or a gap generated between the pachinko machine itself and the front door 12 and the main body member 11 are unlocked, or the main body member 11 and the fixing frame 15 are inserted. There is a player who tries to release the lock.

  For example, even if a foreign object such as a wire is hooked on the door hook 55 and is rotated in the M direction in an attempt to unlock the front door 12 and the main body member 11, the other end 59 b of the connecting rod 59 is connected to the slide plate 58. Therefore, even if the door hook 55 is rotated, the other end 59b of the connecting rod 59 only moves along the long hole 58c of the slide plate 58. The slide plate 58 does not slide. Since the slide plate 58 does not slide, the locking between the door hook 56 and the engagement piece 75 is not released, and the locking between the front door 12 and the main body member 11 is not released. Similarly, even if the door hook 56 is rotated in the Q direction by a foreign object such as a wire, the slide plate 58 does not slide, so that the lock between the door hook 55 and the engagement piece 72 is not released. Thereby, the illegal act which tries to open the front door 12 illegally can be prevented.

  Similarly, even when a wire or the like is hooked on the frame hook 57 and is rotated in the F direction so as to release the locking of the main body member 11 and the fixed frame 15, the other end 60 b of the connecting rod 60 is connected to the slide plate 58. Therefore, even if the frame hook 57 is rotated, the other end 60b of the connecting rod 60 only moves inside the long hole 58d. Do not slide. Since the slide plate 58 does not slide, the locking state of the engagement pin 120 by the locking mechanism 63 is not released, so that the locking of the main body member 11 and the fixed frame 15 is not released. Further, even if it is attempted to release the locking of the engagement pin 120 by the locking mechanism 63 using a wire or the like, the locking mechanism 63 is covered with the protective cover 65, so that the engagement pin 120 by the locking mechanism 63 is used. Cannot be released. Even if a wire is inserted into the protective cover 65, the engagement state of the engagement pin 120 by the engagement mechanism 63 is not released unless the hook lever 95 is rotated. It is possible to prevent an illegal act to unlock the lock illegally.

  As shown in FIG. 17, even if the slide plate 58 is slid using a thin plate made of synthetic resin, so-called cell plate 125, the slide plate 58 is covered with the protective cover 65, so that the wire or cell plate can be removed. The slide plate 58 cannot be hooked. Since only the protruding piece 58f of the slide plate 58 is exposed from the protective cover 65, when the cell plate 125 is slid downward after the cell plate 125 is brought into contact with the upper side 126 of the protruding piece 58f, the cell plate 125 is By sliding on the upper side 126, it moves in the T direction and deviates from the upper side 126 of the protruding piece 58f. Further, after the cell plate 125 is brought into contact with the lower side of the protruding piece 58f, when the cell plate 125 is slid upward, the cell plate 125 moves in the U direction by sliding on the lower side 127, and the lower side 127 of the protruding piece 58f. Deviate from. Thereby, the slide plate cannot be slid by the cell plate 125. The same applies to the wire, and the tip of the wire cannot be hooked on the protruding piece 58f. Thereby, the fraud which cancels | releases locking by the locking device 50 using a wire, a cell board, etc. can be prevented.

  In the present embodiment, the locking device that locks both the main body member and the front door and the locking of the main body member and the fixing frame has been described, but the locking device that locks the main body member and the fixing frame is used. There may be. In the case of a locking device that locks the main body member and the fixed frame, the frame hook 57, the slide plate 58, the connecting rod 60, the cylinder 40, the transmission member 61, the locking mechanism 63, the holding member 64, and the protective cover 65 are provided.
