  However, the device body of this type of slimmed locking device has a narrow and slim front width that is very short and narrow relative to the length in the longitudinal direction (longitudinal direction). For this reason, the device body formed by bending the steel plate into a U-shaped cross section or joining a plurality of plate members causes dimensional errors and shape variations for each product at the time of manufacture, resulting in subtle bending and deformation. Is likely to occur.

  On the other hand, in the apparatus body thus slimmed down, there are a long front frame working rod projecting a front frame cage and a long glass door working rod projecting a glass door cage, It is slidably inserted with a long drive rod.

For this reason, a location where a considerable contact (contact) load occurs between the long working rod and the device main body, such as the inner surface of the device main body, the front frame working rod, or the outer surface of the glass door working rod, Sliding friction resistance between metals tends to increase.

  This conventional slimming locking device has a structure in which when the front frame is closed and the front frame is locked, the force that closes the front frame acts on the side that slides the front frame operating rod. When the frictional resistance when the frame operating rod slides is increased, a relatively large force is required when the front frame is closed and the front frame is locked, and the smooth locking operation is likely to be hindered. Also, when unlocking the front frame, the drive rod and front frame actuation rod slide according to the operation of the cylinder lock and cam, but if the friction resistance when the drive rod and front frame actuation rod slide is large, Smooth unlocking operation tends to be hindered.

  Similarly, when the glass door is closed and locked, the force that closes the glass door acts on the sliding side of the glass door operating rod. When it is increased, there is a problem that the closing force when the glass door is closed and locked is relatively large, and the smooth locking operation is easily hindered.

  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 44 and the front frame 45 at the time of unauthorized unlocking, the unlocking latch operating rod 6 and the glass frame operating rod 10 A fraudulent instrument such as a wire does not reach, and this kind of fraud can be effectively prevented. Also, as shown in FIGS. 2 and 3, there are no protrusions or protrusions such as a flange member on the back side of the case 1, and the inside of the front frame 45 is opened during maintenance inspections, etc. to replace parts. When performing the operation, the operation can be safely performed without interfering with the protrusions of the locking device.

  Further, as shown in FIG. 1, the case 1 is formed to be very thin when viewed from the front, and the locking device can be mounted even in a slight gap at the right end in the front frame 45 of the pachinko machine, and is occupied by the locking device. Space can be greatly reduced. Thereby, the freedom degree of arrangement | positioning design of the electrical equipment with which the front frame 45 is mounted | worn, a mechanical component, etc. can be increased.

  Next, the operation of the locking device of the game machine having the above configuration will be described. When the front frame 45 of the pachinko machine (game machine) is closed with respect to the main body frame 44, as shown in FIG. 11, in the upper and lower opening recesses 11, 12, 21, and 22 of the locking device, The locking pins 41a and 42a of the receivers 41 and 42 enter, and the locking pins 41a and 42a are locked in the locking device by the latching operation of the latch members 4 and 5.

  At the time of such locking, the upper and lower latch members 4 and 5 are rotated in the clockwise direction from the state of FIG. 12 when the locking pins 41a and 42a enter, and the locking pins 41a and 42a are moved to the latch member 4. The latch members 4 and 5 are rotated to the back side against the spring force of the spring members 4c and 5c while being fitted in the lock recesses 4b and 5b.

  As a result, the latch members 4 and 5 rotate to the state shown in FIG. 13. At this time, the engagement pins 6 b and 6 c projecting from the upper end portion and the lower end portion of the latch operating rod 6 are connected to the latch members 4 and 5. The latch members 4 and 5 are latched by the latch portions 4d and 5d, and the latch members 4 and 5 are locked at the positions. As a result, the locking pins 41a and 42a of the receivers 41 and 42 are restrained in the lock recesses 4b and 5b of the latch members 4 and 5 in the opening recesses 11, 12, 21, and 22, and the front frame 45 is locked. It becomes a state.

  Thus, when the front frame 45 is closed and locked, the latch members 4 and 5 rotate against the spring force of the spring members 4c and 5c, and rotate to the locked position and are locked. Since the spring force of 4c and 5c is small and the latch members 4 and 5 rotate independently, the frictional resistance at the time of sliding is small, and the front frame 45 is securely locked only by closing the front frame 45 with a slight force. can do.

  On the other hand, when unlocking the front frame 45, the lock shaft 17a of the cylinder lock 17 is rotated by the key, and the cam member 18 is rotated counterclockwise in FIG. At this time, the engaging projection 18a of the cam member 18 engages with the engaging portion 6a of the latch operating rod 6 and pushes it down.

  By the lowering of the latch operating rod 6, the engaging pins 6b and 6c at the upper end and the lower end are disengaged from the engaging portions 4d and 5d of the latch members 4 and 5, and at this time, the latch members 4 and 5 are spring members. As shown in FIG. 12, the spring force of 4c and 5c rotates counterclockwise, and the locking pins 41a and 42a of the receivers 41 and 42 are disengaged from the lock recesses 4b and 5b, and the front frame 45 is unlocked. The After the unlocking operation, the latch members 4 and 5 hold the state of FIG. 12 by the spring force of the spring members 4c and 5c.

  On the other hand, when the glass frame 46 in the front frame 45 is closed with respect to the front frame 45, the glass frame 46 is pushed against the front frame 45 and closed. At this time, the glass frame holder 43 provided on the inner side of the glass frame 46 first strikes the inclined surface of the head of the glass frame collar members 7, 8, 9 and tilts upward to reach the locking position. Then, the glass frame rod members 7, 8, 9 return to the horizontal position (downward) by the biasing force of the spring members 7b, 8b, 9b, and the glass frame rod member 7 is placed on the glass frame holder 43 as shown in FIG. , 8, 9 are locked, and the glass frame 46 is locked.

  Thus, when the glass frame 46 is closed and locked, each glass frame collar member 7, 8, 9 hits the glass frame holder 43, and is tilted upward by receiving an upward rotational force, and then the spring member 7 b. , 8b, 9b return the glass frame rod members 7, 8, 9 to the horizontal position, and the glass frame rod members 7, 8, 9 are locked only by the tilting operation. Accordingly, the sliding frictional resistance generated between the glass frame rod members 7, 8, 9 and the support member 2 is small, and the glass frame 46 can be reliably locked only by closing the glass frame 46 with a slight force.

  On the other hand, when unlocking the glass frame 46, the lock shaft 17a of the cylinder lock 17 is rotated by the key, and the cam member 18 is rotated in the clockwise direction in the figure. At this time, the engaging convex portion 8b of the cam member 18 engages with the engaging portion 10a of the glass frame operating rod 10 and pushes it up slightly.

  As the glass frame operating rod 10 is raised, the engaging pins 10b, 10c, and 10d provided at the upper end portion, the center portion, and the lower end portion thereof are engaged with the engaging portions 7c at the intermediate portions of the glass frame rod members 7, 8, and 9, respectively. , 8c, 9c, the glass frame rod members 7, 8, 9 are tilted upward. As a result, the glass frame collar members 7, 8, 9 are tilted upward as shown in FIG. 13 to disengage from the glass frame holder 43, and the glass frame 46 is unlocked.

  Thus, when the front frame 45 or the glass frame 46 is closed, the locking operation is performed by the rotation of the latch members 4 and 5 or the tilting of the glass frame rod members 7, 8 and 9. In the case of 5, the unlocking operation is performed by the rotation by the spring force of the spring members 4c and 5c of the latch members 4 and 5, so that the latch operating rod 6 and the glass frame operating rod 10 in the slimmed case 1 are slid. Regardless of the dynamic frictional resistance, the locking / unlocking operation is performed, and even when there is a dimensional error or variation in the shape of each part, the locking / unlocking can be performed smoothly.

  Further, since the latch members 4 and 5 are pivotally supported inside the case 1, there is no hook-like portion protruding on the back side of the locking device. For this reason, when opening the front frame 45 and inspecting the inside of the game machine, the movement of hands and tools etc. will not interfere with the protruding part of the locking device and work safely and smoothly. Can be performed.

  Moreover, since the front frame locking mechanism A including the latch members 4 and 5 and the latch actuating rod 6 is almost completely housed in the case 1, a wire or the like is inserted through the gap in the front frame, and it is pulled to the front locking mechanism A. Even if it is attempted to perform unauthorized unlocking by hanging, the wire or the like does not reach the locking mechanism A in the case 1, and unauthorized unlocking using an unauthorized instrument such as a wire can be prevented.

  Further, in the latch operating rod 6 of the front frame locking mechanism A, the engaging pins 6b and 6c attached to the upper and lower ends thereof are inserted into the guide holes 26 and 27, and the latching portions of the latch members 4 and 5 are inserted. Since it is locked to 4d and 5d, the guide pin and the engagement pin that guide the sliding of the latch operating rod 6 can be used together, and the structure can be simplified and the number of parts can be reduced.

  Similarly, in the glass frame operating rod 10 of the glass frame locking mechanism B, guides for guiding the sliding of the glass frame operating rod 10 with the engagement pins 10b, 10c, and 10d attached to the upper end portion, the intermediate portion, and the lower end portion thereof. The pin can also be used, and the structure can be simplified and the number of parts can be reduced.

  In the above embodiment, the support member 2 is formed by pressing a metal plate or the like. However, the support member 2 can also be formed of a synthetic resin. In the case of a support member made of synthetic resin, the thickness of the support member is formed so as to be closely inserted into the case 1 so that the support member is closely fitted into the case 1. As described above, by closely fitting the synthetic resin support member into the case 1, the synthetic resin support member having low bending strength can be used without any problem.

  Further, in this case, it is only necessary to form recesses in which the latch members 4 and 5 and the glass frame collar members 7, 8 and 9 are rotatably or tiltably housed on the inner surface of the support member. What is necessary is just to form the recessed part for accommodating the latch operating rod 6 and the glass frame operating rod 10 in the surface. Further, the pivots 4a and 5a for the latch members 4 and 5 can be projected as bosses on a synthetic resin support member, and the pivots 7a, 8a and 9a for the glass frame rod members 7, 8, and 9 are also made of synthetic resin. It can project as a boss on a support member made of metal.

  In the above embodiment, the locking device for a pachinko machine has been described. However, the locking device of the present invention may be applied to a game machine having only a front frame (front door) that does not have a glass frame such as a slot machine. it can. In this case, there is no glass frame locking mechanism, only the front frame locking mechanism is assembled to the support member, and the support member is housed in the case. When the reset switch is operated by a key as in the slot machine, the switch operating rod is slidably disposed along the left side surface of the support member, and the switch operating rod can be engaged with the cam member. The operating rod is also stored in the case. When the key inserted into the cylinder lock is turned to the unlocking side (left side) of the front door, the switch operating rod is operated.
