  The receiving brackets 23 and 24 are fixed to the corresponding positions of the front frame lock claws 2 and 3 in the main body frame 20. As shown in FIG. 7A, the catching portions 23a, 24a are formed by bending the mounting portions 23a, 24a at right angles from the mounting portion, and a rectangular shape is formed in a part of the catching portions 23a, 24a. Locking holes 23b and 24b are formed. On the other hand, a glass frame 22 is attached to the front side of the front frame 21 through a hinge so as to be openable and closable, and a pair of edges is attached to the edge of the front portion of the front frame 21 into which the glass frame 22 is fitted when the glass frame 22 is closed. The glass frame lock claws 6 and 7 protrude. And the receiving metal fittings 25 and 26 which can latch the glass-frame lock nail | claws 6 and 7 at the time of closing of the glass frame 22 are attached to the inner side of the glass frame 22 inside the glass frame 22. As shown in FIG. 7 (b), the receiving metal parts 25 and 26 are formed with locking portions 25a and 26a on a flat plate portion bent at a right angle. A part of the locking portions 25a and 26a has a rectangular shape. Locking holes 25b and 26b are formed.

  When the front frame 21 is closed with respect to the main body frame 20 of the pachinko gaming machine, as shown in FIG. 13, the inclined front ends of the front frame lock claws 2 and 3 of the locking device are formed on the receiving metal fittings 23 and 24 inside the main body frame 20. The front frame locking claws 2 and 3 come into contact with the locking portions 23a and 24a and once slide upward and return to the original state by the urging force of the spring members 14 and 15, so that the front frame locking claws 2 and 3 The locking recesses are locked to the locking portions 23a, 24a of the receiving metal fittings 23, 24. At the same time, the tip claws 4b and 5b of the swinging and locking claws 4 and 5 pivotally supported on the side surfaces of the front frame lock claws 2 and 3 are rotated counterclockwise in FIG. 13 by the urging force of the spring members 14 and 15.

  On the other hand, when the glass frame 22 is closed with respect to the front frame 21, the tip inclined portions of the pair of glass frame locking claws 6, 7 come into contact with the locking portions 25 a, 26 a of the receiving brackets 25, 26 of the glass frame 22 once. By sliding downward and returning upward by the biasing force of the spring members 18, 19, the glass frame lock claws 6, 7 are locked to the locking portions 25 a, 26 a of the glass frame 22. At the same time, the tip claws 16b and 17b of the swinging and locking claws 16 and 17 pivotally supported on the side surfaces of the glass frame lock claws 6 and 7 are rotated counterclockwise in FIG. 9 by the urging force of the spring members 18 and 19. It moves and is inserted into the locking holes 25b, 26b of the metal fittings 25, 26 and locked, and the locked state as shown in FIG. 6 is obtained.

  Therefore, in the locked state of the glass frame 22, the glass frame lock claws 6, 7 are locked to the locking portions 25 a, 26 a of the receiving brackets 25, 26, and the rocker pivotally supported by the glass frame lock claws 6, 7. The front end claw portions 16b and 17b of the dynamic locking claws 16 and 17 are fitted into the locking holes 25b and 26b of the receiving metal fittings 25 and 26 and locked. Therefore, even if an illegal instrument such as a wire is inserted through the gap between the glass frame 22 and the front frame 21 of the gaming machine and hooked at the tip, the glass frame lock claws 6 and 7 are moved to the unlocking side. As shown in FIGS. 8 and 9, the locking claws 6 and 7 have the front end claw portions 16 b and 17 b of the swinging locking claws 16 and 17 integrally fitted in the locking holes 25 b and 26 b of the receiving metal fittings 25 and 26. Locked and cannot be moved to unlock. Therefore, the glass frame lock claws 6 and 7 cannot slide downward, and it is impossible to slide the glass frame lock claws 6 and 7 downward by inserting a wire or the like from the gap of the glass frame 22. Unauthorized unlocking can be prevented.

  Similarly to the above, in the locked state, the first and second engaging protrusions 10a and 10b of the cam member 10 are operated while being held in the engagement holes 8i and 8j of the operating band plate 8. The movement of the strip 8 is locked. In other words, in the cylinder lock 9 with the key removed, the lock shaft 9b cannot rotate and cannot rotate, so the cam member 10 is locked by the cylinder lock 9, and the operating band plate 8 is fixed to the cam member 10. Is prevented from sliding up and down. For this reason, even if it is attempted to slide the glass frame lock claws 6 and 7 by hooking the tip of the unauthorized device and moving the glass frame lock claws 6 and 7, the glass plate 22 is prevented from being slid to prevent unauthorized unlocking. can do.

Further, when the operating band plate 8 moves upward, the engaging convex portions 8e and 8f of the operating band plate 8 engage with the engaging portions 2b and 3b of the front frame locking claws 2 and 3, and the swing locking claw 4 , 5, the table frame lock claws 2, 3 are lifted upward against the urging force of the spring members 14, 15. As a result, as shown in FIGS. 11 and 14, the front frame locking claws 2 and 3 slide upward to disengage from the engaging portions 23 a and 24 a of the receiving brackets 23 and 24, and the front frame 21 is unlocked.

  When unlocking the glass frame 22, when the key is inserted into the cylinder lock 9 and the key is turned counterclockwise, the second engaging convex portion 10b of the cam member 10 is rotated clockwise in FIG. Is moved downward. At this time, the engaging projections 8g and 8h of the operating band plate 8 are first engaged with the engaging portions 16c and 17c of the swinging locking claws 16 and 17 pivotally supported on the side surfaces of the glass frame lock claws 6 and 7, respectively. Then, the rocking locking claws 16 and 17 are rotated clockwise in FIG. 12 against the urging force of the spring members 18 and 19. As a result, the front end claw portions 16b and 17b of the swinging locking claws 16 and 17 are disengaged from the locking holes 25b and 26b of the receiving metal fittings 25 and 26, and subsequently, the engagement convex portions 8g and 8h of the operating band plate 8 are moved. The glass frame lock claws 6 and 7 are engaged with the engaging portions 6b and 7b and pushed down, and the glass frame lock claws 6 and 7 slide downward. Thereby, as shown in FIG. 12, the engagement between the glass frame lock claws 6 and 7 and the engaging portions 25a and 26a of the metal fittings 25 and 26 of the glass frame 22 is released, and the glass frame 22 is unlocked.

  Thus, when the front frame 21 is locked, the front frame lock claws 2 and 3 are locked, and when the glass frame 22 is locked, the glass frame lock claws 6 and 7 are locked, and both the front frame 21 and the glass frame 22 are locked.
