At this time, with the rotation of the latch members 3 and 4, the locking pins 3b and 4b move away from the open portions 6b and 7b of the guide holes 6 and 7 to the central portion, and the operating rod 10 is coil spring at the central portion. It descends by the urging force of 11 and 12. At this time, the locking pins 3b and 4b are relatively raised to the locking portions 6a and 7a of the guide holes 6 and 7, and the locking pins 3b and 4b are locked. 18, the cylindrical members 35 and 51 are held in a state of being restrained in the restraining recesses 3 a and 4 a, and the front door 56 is locked to the cabinet 55.

  On the other hand, when unlocking the front door 56, as shown in FIG. 19, a key is inserted into the cylinder lock 32 of the cylinder lock unit 30, and the key is turned clockwise. At this time, the cam member 33 rotates in the same direction and engages with the engaging portion 47 of the cam member 33 to push up the sliding member 34. Thereby, the sliding member 34 rises, the engaging pin 39 attached to the upper part thereof rises, and pushes up the receiving engagement portion 13 of the operating rod 10 of the cabinet side unit 1.

  At this time, as shown in FIG. 19, the latch pins 3 b, 4 b of the latch members 3, 4 are relatively lowered in the guide holes 6, 7, as shown in FIG. 19, and the latch portions 6 a, 7 a are moved. Move away to the center. At this time, the latch members 3, 4 are rotated clockwise as shown in FIG. 20 by the urging force of the coil springs 11, 12, whereby the cylindrical members 35, 51 are restrained recesses 3 a, 4 a of the latch members 3, 4. Is released and unlocked, and the front door 56 of the cylinder lock unit 30 is opened as shown in FIG.

  By the way, in a pachinko hall or the like where a game machine is actually used, when the clerk locks after opening the front door 56 of the game machine, the key is usually held with the key inserted into the cylinder lock 32. Close the front door 56.

  In such a case, the force that closes the front door 56 is transmitted straight from the cylinder lock 32 to the support roller 37 located immediately behind the cylinder lock 32, and the support roller 37 rolls on the roller support portion 8 of the cabinet side unit 1. Then, when the front door 56 is closed while being lifted slightly, a bending moment or the like does not act, and acts directly as a closing force. For this reason, even if the user has the key, the user can smoothly close the front door 56 with a small closing force and securely lock it.

  In the above embodiment, the cylindrical member 35 of the receiving metal fitting is attached to the upper part of the base frame 31 of the cylinder lock unit 30, but the receiving metal fitting may be provided separately from the base frame 31. On the contrary, the column member 51 of the lower receiving metal fitting 50 can extend the lower part of the base frame 31 downward, and can attach the lower column member to the lower part.
