As a result, the upper and lower flange members 4 and 5 tilt upward about the shaft pins 4b and 5b, disengage from the locking portions 14 and 15 of the cylinder lock unit 1 on the front door 30 side, and the front door 30 Is unlocked.

  When the front door 30 is opened, the operation panel 23 located inside the front door 30 is pushed down to slide the lower panel locking member 20 downward against the urging force of the coil spring 24. The 20 flange portions 21 and 22 slide downward to disengage from the engaging portions 32 and 33 provided inside the lower panel 31. Thereby, the lower panel 31 is unlocked, the lower panel 31 is opened with respect to the front door 30, and a maintenance check etc. can be performed.

  On the other hand, when performing a reset operation of the game machine, a key is inserted into the keyhole of the cylinder lock 17 and the key is turned to the left to rotate the engagement member 18 in the same direction. At this time, the operating piece 18b of the engagement member 18 enters the detection portion (insertion space) of the non-contact switch 10, and the non-contact switch 10 performs a switching operation to generate a reset signal in the game machine.

  Note that, depending on the formation of the front door, there may be a problem that the front door is not only deformed so that the right end of the front door faces and exits to the right side, but also deformed to the left side. In order to cope with such a case, as shown in FIG. 17, the position shift correcting member 225 a and 225 b are provided on both left and right sides of the front end portion of the position shift correcting member 225 and the slopes 225 a and 225 b are provided on both sides thereof. The member 225 is attached to a part of the base frame body 212 of the locking device, and when the front door 30 is closed, the positional deviation correction member 225 is attached to the receiving portion 202a provided on the base frame body 202 fixed to the housing 28 side. A structure to be inserted. The receiving portion 202a is formed with inclined surfaces on both the left and right sides, and the inclined portions 225a and 225b on both sides of the front end portion of the positional deviation correcting member 225 can come into contact with the inclined surfaces on both the left and right sides. Thereby, even if the right end portion of the front door is deformed to the left or the right side, the displacement of the locking device due to the deformation can be corrected.

  As described above, according to the locking device for a game machine of the present invention, the upper right end portion of the front door body is deformed so as to come out, for example, and the cylinder lock unit is shifted to the right side toward the front door. Even so, when the front door is closed, the positional deviation is corrected, and the flange member of the base frame body is correctly locked to the locking portion of the cylinder lock unit or the receiving metal fitting. Therefore, even when the left and right lateral deformation of the front door is large, the collar member can be correctly engaged with the locking portion and can be reliably and normally locked.
