  In this type of locking device, when the front frame is closed with respect to the main body frame in order to lock the front frame, the upper and lower hooks of the sliding rod are placed on the latching portion of the catch fixed to the main body frame. Upon hitting, the hook part moves once together with the sliding hook in the unlocking direction, returns to the original position, is locked to the hook-like locking part, and is locked.

  However, this type of locking device has a form in which the hook-shaped flange protrudes from the base frame body of the locking device in a state where the front frame is unlocked and opened. It may interfere with an operator who has opened the front frame for inspection work, and if possible, it is desirable that the collar does not protrude outward from the base frame body of the locking device. In addition, when transporting the locking device with the collar protruding from the base frame when the locking device is transported to the place of the assembly process of the gaming machine at the manufacturing stage, the collar will interfere with other members. It is easy to carry out, and the trouble in the middle of conveyance tends to arise by interference of a collar part. Furthermore, when unauthorized unlocking is performed such that a wire, wire, or the like is inserted through a gap in the gaming machine, in the form in which the collar portion protrudes from the base frame body of the locking device, the wire, wire, or the like is likely to be applied to the collar portion. There was a possibility of unauthorized unlocking.

  On the other hand, in Patent Document 2, as a gaming machine locking device, there is a gaming machine locking device that locks a pin-like striker fixed on the main body frame side between a pivotable hook and a pole. Proposed. In this gaming machine locking device, a hook and a pole for locking a striker are rotatably mounted in a long base, and the hook and the pole are disposed in the base, and the number of members protruding outward from the base is reduced. I am doing so.

  However, the shape of the hook and pole becomes complicated and becomes relatively long in the front-rear direction, and the hook and ball with a complicated structure are exposed on the side of the locking device. Since the width is wide and exposed, when viewed from the whole locking device, the locking device protrudes to the back side at the hook and pole part that locks the striker, and the hook, pole, slider, coil spring, etc. Large exposure on the side of the base.

  For this reason, when the front frame is opened, such as during inspection work of a gaming machine, hooks, poles, sliders, coil springs, etc. of the locking device are likely to interfere with the operator and other members. Even during conveyance, there is a problem that hooks, poles, sliders, coil springs, and the like interfere with other members, and problems such as parts coming off during conveyance are likely to occur.

  Furthermore, this locking device has a large number of parts such as hooks, poles, sliders, coil springs, etc., increases the manufacturing process, increases the manufacturing cost, and has large hooks, poles, sliders, coil springs, etc. on the side of the device. Because it is exposed, if unauthorized unlocking is performed, such as inserting a wire or wire through a gap in the gaming machine, the hook, pole, slider, coil spring, etc. are likely to be caught with the wire or wire, and unauthorized unlocking is performed. The potential is great.

  The present invention has been made to solve the above-mentioned problems, and has a simple structure, can be configured compactly without protrusions on the back side and the front side, and can interfere with other members during transportation or use of the apparatus.

In addition, since the hook members 5 and 6 for locking the front frame 51 and the flange members 14 and 15 for locking the glass frame 52 are slidable independently, it also prevents unauthorized unlocking. can do.

  Next, the operation of the gaming machine locking device having the above configuration will be described. When the front frame 51 in the pachinko machine is closed with respect to the main body frame 50, as shown in FIGS. 12 to 15, the locking plate 54 of the receiving metal 53 is inserted into the hook members 5, 6 from the receiving opening 1 a of the base frame 1. The hook members 5 and 6 rotate in the clockwise direction in FIGS. 12 and 16 while entering the locking recesses 5 b and 6 b and resisting the biasing force of the coil springs 12 and 13.

  At this time, the hook protrusions 5c of the hook members 5 and 6 push the inclined protrusions 10a and 11a of the lock members 10 and 11 so that the lock members 10 and 11 slide downward, as shown in FIGS. When the hook members 5 and 6 are rotated to the locked position, the engaging convex portions 5c and 6c are locked to the inclined convex portions 10a and 11a as shown in FIGS. It will be in the locked state locked so that the latching plate 54 of the metal fitting 53 might be wound.

  On the other hand, when unlocking the front frame 51, the lock shaft 7a of the cylinder lock 7 is rotated clockwise by the key, and the cam member 9 is rotated in the same direction. At this time, the engaging convex portion 9a of the cam member 9 engages with the upper portion of the engaging portion 8a of the operating rod 8 and pushes the operating rod 8 downward.

  When the operating rod 8 is lowered, the engaging portions 8b and 8c are engaged with the engaging portions 10b and 11b of the lock member, and the lock members 10 and 11 are lowered. By the lowering of the lock members 10 and 11, the inclined convex portions 10a and 11a are disengaged from the engaging convex portions 5c and 6c of the hook members 5 and 6, and the hook members 5 and 6 are connected to the coil springs 12 and 13, respectively. By the spring force, it rotates counterclockwise, that is, to the back side to the position of FIGS. 14 and 16, and the front frame 51 is unlocked. At this time, the protruding portions 5d and 6d in which the hook members 5 and 6 bulge act so as to push out the locking plate 54 of the receiving metal 53, so that the front frame 51 receiving the reaction force is pushed out to the front surface. Can be opened lightly.

  On the other hand, when the glass frame 52 in the table frame 51 is closed with respect to the table frame 51, the glass frame 52 is pushed against the table frame 51 and closed. At this time, as shown in FIG. 11, the glass frame receiving portion 56 provided on the inner side of the glass frame 52 hits the inclined surface of the head portion of the flange members 14 and 15, and slides it upward to bring it into the locking position. When reaching, the urging members 14 and 15 are returned to the original positions (downward) by the urging force of the coil springs 16 and 17, whereby the urging members 14 and 15 are locked to the glass frame receiving portion 56 as shown in FIG. The glass frame 52 is locked.

  On the other hand, when unlocking the glass frame 52, the lock shaft 7a of the cylinder lock 7 is rotated to the left opposite to that when unlocking the front frame by the key, and the cam member 9 is rotated in the same direction. At this time, the lower engaging projection 9b of the cam member 9 engages with the lower portion of the engaging portion 8a of the operating rod 8 to push it up.

  As the operating rod 8 is raised, the engaging portions 8d and 8e hit the engaging convex portions 14a and 15a of the glass frame rod members 14 and 15 and push them up. As a result, the flange members 14 and 15 for the glass frame slide upward against the spring force of the coil springs 16 and 17, and at this time, the glass frame receiving portion 56 comes off from the flange members 14 and 15, and the glass The frame 52 is unlocked.

  As described above, the hook members 5 and 6, the lock members 10 and 11, the coil springs 12, 13, 16, and 17 and the operating rod 8 are compactly arranged in the channel-shaped base frame 1 to reduce the number of locking devices. It can be manufactured more inexpensively with the number of parts and the number of processing steps. In addition, since the hook members 5 and 6, the lock members 10 and 11, and the coil springs 12, 13, 16, and 17 are accommodated in the base frame, an unauthorized unlocking in which a wire, a wire, or the like is inserted through a gap in the gaming machine Even if the operation is performed, it is difficult for the hook member, the lock member, the coil spring, and the like to be covered with a wire, a wire, or the like, and unauthorized unlocking can be prevented.

  Furthermore, there is almost no part protruding outward from the base frame 1, and avoids interference between the hook members 5 and 6, the lock members 10 and 11, coil springs, and other members during transport and actual use. When the transport apparatus is used and the locking device is attached to the gaming machine and used, it is possible to avoid interference with the operator when the table frame 51 is opened when the gaming machine is inspected.

  In addition, both the front frame 51 and the glass frame 52 of the gaming machine can be locked by a compact locking device, and the front frame 51 or the glass frame 52 can be locked by sliding up or down one operating rod 8. Can be easily unlocked. Further, the operating rod 8 is in a neutral position by the coil springs 16 and 17 for biasing the glass frame rod members 14 and 15 to the locking side and the coil springs 12 and 13 for biasing the lock members 10 and 11. Since it is held, by a relatively simple structure with a small number of parts, during the unlocking operation, the operating rod 8 is slid up or down with a light operating force via the cam member 9, and the table frame 51 or the glass frame 52 can be unlocked smoothly.

  The hook members 5 and 6 are provided with the plate-like engagement protrusions 5c and 6c as engaging portions that can be engaged with the inclined protrusions 10a and 11a of the lock members 10 and 11, respectively.
