Thus, the sliding member 20 can slide up and down in the range of the guide hole 25 with respect to the rod sliding rod 10.

  With such a structure, when the cam member 8 is rotated counterclockwise in FIG. 3 in accordance with the rotation of the cam member 8, that is, by the rotation operation of the cylinder lock 7, The first engaging convex portion 8 a engages with the cam engaging portion 23, the sliding member 20 slides downward, and the second engaging portion 22 is the engaging convex portion 31 of the front frame locking member 30. In this case, the front frame locking member 30 is rotated in the unlocking direction.

  On the other hand, when the cam member 8 is rotated in the clockwise direction in FIG. 3 by the cylinder lock 7, the second engaging convex portion 8b is engaged with the cam engaging portion 24, and the sliding member 20 is slid upward. Then, the first engaging portion 21 hits the engaging convex portion 41 of the glass frame locking member 40, and the glass frame locking member 40 is rotated in the unlocking direction.

  As shown in FIGS. 9 to 11, the locking device configured as described above exposes the front end of the cylinder lock 7 on the front side inside the free end side of the front frame 51 made of, for example, synthetic resin in the pachinko machine, With the front frame flanges 11 and 12 of the sliding rod 10 protruding toward the main body frame 50 side of the pachinko machine, insert the fixing screws into the mounting holes of the mounting piece 3 and the lock mounting plate 4 and screw them in vertically. Mounted on.

  On the other hand, receiving brackets 53 and 54 are fixed at the upper and lower positions corresponding to the front frame flanges 11 and 12 inside the main body frame 50. A locking plate for locking the collar portion protrudes from the metal fittings 53 and 54. The glass frame 52 attached to the front surface of the front frame 51 so as to be openable and closable is provided with glass frame receiving brackets 55 and 56 at positions corresponding to the glass frame flanges 13 and 14. A locking plate for locking the collar portion protrudes from the metal fittings 55 and 56.

  As shown in FIG. 10, this locking device is vertically installed inside the free end side edge of the front frame 51 of the pachinko machine, but as shown in FIG. The unlocking member does not appear, and the slidable sliding rod 10 for both the front frame and the glass frame including the unlocking sliding member 20 is housed inside the base frame 1 having the U-shaped main body 2, The back side of 1 is closed except for the protrusions of the flanges 11 and 12 for the front frame. For this reason, even when a wire or the like is inserted from the gap on the free end side of the main body frame 50 and the front frame 51 at the time of unauthorized unlocking, both the front frame and the glass frame including the sliding member 20 for unlocking are used. Such an unauthorized device such as a wire does not arrive at the slidable sliding rod 10, and this kind of unauthorized unlocking can be effectively prevented.

  Further, as shown in FIG. 9, the U-shaped main body 2 of the base frame 1 is formed to be very thin when viewed from the front, and the occupied space occupied by the locking device is extremely reduced in the front frame 51 of the pachinko machine. As a result, the degree of freedom in the layout design of electrical equipment and machine parts mounted in the front frame 51 can be increased.

  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 FIG. 15, first, the inclined front ends of the upper and lower front frame collars 11 and 12 of the locking device are the receiving metal 53 on the main body frame 50 side. , 54.

  Then, the saddle sliding saddle 10 integrated with the front frame flanges 11 and 12 receives a downward force and slides downward, and the front frame flanges 11 and 12 are engaged with the receiving brackets 53 and 54. Increase the match. Further, when the receiving metal fittings 53 and 54 come into contact with the locking projection 32 of the front frame lock member 30, the front frame lock member 30 is slightly rotated counterclockwise as shown in FIG. When the receiving brackets 53 and 54 are engaged with the engaging portions of the front frame flanges 11 and 12, the saddle sliding rod 10 is returned to the original position by the biasing force of the torsion spring 9 (ascended). At the same time, as shown in the right figure of FIG. 15, the front frame flanges 11 and 12 are locked to the receiving brackets 53 and 54 to be locked.

The stop convex part 32 is located. When the front frame collars 11 and 12 are locked, the vertical sliding bar 10 slides up and down. At this time, the glass frame collars 13 and 14 also slide up and down, but as described above. Since the glass frame flanges 13 and 14 have stepped portions even in the locked state, the glass frame flanges 13 and 14 slide on the locking surfaces of the glass frame brackets 55 and 56, and the glass sliding rod 10 The downside is not hindered.

  As a result, the upper and lower portions of the receiving metal fitting 54 are sandwiched between the upper projection 12 and the upper projection 32 of the front frame lock member 30, that is, when the lower projection 10 is lowered, the upper projection 32 is received. As a result, the table frame lock member 30 is pivotally supported and the table slide collar 10 having the table frame flanges 11 and 12 is prevented from being lowered and locked. . Therefore, in such a locked state, even if a wire or the like is inserted from the gap between the front frame and the main body frame, and the heel sliding rod 10 is slid downward, the sliding is impossible, and the incorrect determination of the front frame 51 Locking can be prevented.

  On the other hand, when unlocking the front frame 51, the lock shaft 7a of the cylinder lock 7 is rotated by the key, and the cam member 8 is rotated counterclockwise in FIG. At this time, as shown in FIG. 16, the first engaging convex portion 8a of the cam member 8 is first engaged with the cam engaging portion 23 of the unlocking sliding member 20 and slightly pushed down.

  As the sliding member 20 descends, the second engaging portion 22 at the lower end of the sliding member 20 abuts against the engaging convex portion 31 of the front frame locking member 30 pivotally supported by the base portion of the front frame collar 12, and this slightly Press down. As a result, the front frame locking member 30 is slightly rotated counterclockwise as shown in FIG. 16, and at this time, the engaging protrusion 32 of the front frame locking member 30 is moved from the engaging position of the receiving metal fitting 54. The table frame collar 12 is unlocked.

  Next, the first engaging convex portion 8a of the cam member 8 is further rotated downward to engage with the cam engaging portion 16 of the eaves sliding rod 10 located at the back of the sliding member 20. , Push it down to lower it. With the lowering of the saddle sliding saddle 10, the front frame collars 11 and 12 are lowered as shown in FIG. 16, and as a result, the front frame collars 11 and 12 and the receiving brackets 53 and 54 of the main body frame 50 Is disengaged, the front frame 51 is unlocked, and can be opened.

  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. 17, the metal fittings 55 and 56 provided on the inner side of the glass frame 52 first hit the inclined surface of the head portion of the glass frame flanges 13 and 14 of the rod sliding rod 10, When the hook sliding rod 10 is slid downward together with the rod sliding rod 10 and reaches the locking position, the rod sliding rod 10 is returned to the original position (downward) by the urging force of the torsion spring 9, so that the right diagram of FIG. As described above, the glass frame collars 13 and 14 are locked to the metal fittings 55 and 56, and the glass frame 52 is locked.

  At this time, the glass frame locking member 40 is slightly rotated in the clockwise direction in FIG. 17, and the glass frame locking member 40 is locked directly below the glass frame flanges 13 and 14 with the receiving metal fittings 55 and 56 interposed therebetween. The convex part 42 is located. In other words, when the eaves sliding rod 10 is raised, the locking projection 42 can be engaged with the receiving metal piece 56, the elevating of the eaves sliding rod 10 is prevented, and unauthorized unlocking is prevented. In addition, when the glass frame collars 13 and 14 are locked, the glass sliding collar 10 slides up and down. At this time, the integrated front frame collars 11 and 12 also slide up and down, as described above. Even if the front frame collars 11 and 12 are in a locked state, as shown in FIG. , 54 can be slid all the way to the back, and the lowering operation of the eaves sliding rod 10 is not hindered.

  As a result, the upper and lower sides of the metal fitting 56 are sandwiched between the locking projections 42 of the glass frame collar 14 and the glass frame locking member 40, that is, when the collar sliding rod 10 is raised, the locking projections 42 are received. As a result, the glass frame lock member 40 is pivotally supported and the eaves sliding rod 10 having the glass frame collar portions 13 and 14 is prevented from being raised and locked. Therefore, in such a locked state, even if an attempt is made to slide the saddle sliding rod 10 by inserting a wire or the like from the gap between the front frame and the main body frame, the sliding rod 10 cannot be moved in the unlocking direction. Thus, unauthorized unlocking of the glass frame 52 can be prevented.

  On the other hand, when unlocking the glass frame 52, the lock shaft 7a of the cylinder lock 7 is rotated by the key, and the cam member 8 is rotated clockwise in FIG. At this time, as shown in FIG. 18, the second engaging convex portion 8b of the cam member 8 first engages with the cam engaging portion 24 of the unlocking sliding member 20 to slightly push it up.

  As the sliding member 20 is lifted, the first engaging portion 21 at the upper end of the sliding member 20 comes into contact with the engaging convex portion 41 of the glass frame locking member 40 pivotally supported by the base portion of the glass frame collar portion 14, and this is slightly changed. Push up. As a result, the glass frame locking member 40 is slightly rotated counterclockwise as shown in FIG. 18. At this time, the locking projection 42 of the glass frame locking member 40 moves from the locking position of the metal fitting 56. The glass frame collar 14 is unlocked.

  Next, the second engaging convex portion 8b of the cam member 8 is further rotated upward to engage with the cam engaging portion 17 of the saddle sliding rod 10 at the back of the sliding member 20, and this. Push up to raise. As shown in FIG. 18, the glass frame flanges 13, 14 are raised by the rising of the saddle sliding rod 10, whereby the glass frame flanges 13, 14 and the metal frame 55, 56. Is disengaged, and the glass frame 52 is unlocked and becomes openable.

  In this way, the front frame collar portions 11, 12 and the glass frame collar portions 13, 14 are integrally formed on the front frame / glass frame collar sliding rod 10, and the base portion of the glass frame collar portion 14 is formed. A glass frame lock member 40 is pivotally supported, a front frame lock member 30 is pivotally supported at the base of the front frame collar 12, and one unlocking sliding member is provided along the collar slide rod 10. Since 20 is slidably mounted, the mechanism for locking both the locking mechanism for the table frame and the locking mechanism for the glass frame in the locked state can be configured with a very small number of parts. It is possible to reduce the number of assembling steps when manufacturing the locking device, and to manufacture a highly reliable locking device with a low manufacturing cost.

  Further, the locking mechanism using the front frame locking member 30 and the glass frame locking member 40 has a structure that can be locked to the metal fittings 54 and 56 by receiving the locking projection 32 and the locking projection 42 at the ends thereof. Because the locked sliding rod 10 is locked, the structure of the locking mechanism can be greatly simplified. Further, it is not necessary to increase the dimensional accuracy of the parts including the front frame lock member 30 and the glass frame lock member 40, and rough and sufficient, and adjustment during assembly is not required. For this reason, a locking device can be manufactured at low cost.

  In addition, since the single torsion spring 9 is used as a return spring that generates a return force to the original position when the sliding / sliding rod 10 also used as the front frame / glass frame is raised or lowered, the number of spring members is reduced. can do.

  Further, a U-shaped main body 2 having a U-shaped cross section is used for the base frame 1, and the front frame / glass frame combined with a saddle sliding rod 10, a front frame lock member 30, a glass frame lock member 40, and Since the sliding member 20 for unlocking is accommodated in the U-shaped main body 2, the outer shape of the base frame 1 can be formed thin and slim while maintaining the bending strength necessary for the base frame 1. Thereby, the space occupied in the table frame 51 occupied by the locking device can be reduced, and the space in the table frame 51 can be given a margin, so that the degree of freedom in the layout design of the internal electrical equipment and machine parts can be increased.
