There is sometimes provided an actuating engagement portion that operates to engage with the latching pin of the latch member and release the lock by the lock portion, and a spring member that biases the latch member toward the unlocking side is incorporated.

  In this locking device, when the front frame is closed and the locking operation is performed, the latching portion of the receiving member is inserted into the latch recesses of the upper and lower latch members, and the latch member is pushed by the latching portion. When the latch member rotates to the latch position, the latch pin of the latch member moves from the guide latch hole to the lock portion, and the latch member is locked at the latch position and locked.

  By the way, when this type of locking device is used in a game machine and installed in a pachinko hall, etc., when an illegal instrument such as a wire inserted from the gap in the front frame is caught on the operating rod and pulled in the unlocking direction There was a risk of unauthorized unlocking.

  In addition, a function switch used for resetting a game may be attached to a locking device of this type of game machine. In this case, a switch operating rod is slidably disposed in the base frame. When the cam member is rotated in the direction opposite to the unlocking side by the operation of the cylinder lock, the cam member is engaged with the switch operating rod and moved to switch the function switch.

  However, when the switch operating rod is arranged in the base frame, a guide hole such as a guide hole or a guide pin for guiding and holding the switch operating rod is required, and the switch operating rod is not operated. For example, a spring member for biasing in the direction is required, so that the number of parts is increased and the number of assembling processes is increased.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a locking device for a game machine that can prevent unauthorized unlocking by illegally moving an operating rod.

In order to achieve the above object, the locking device according to claim 1 of the present invention comprises:
A long operating rod is slidably disposed along the support plate of the base frame having a mounting plate and a support plate, a cylinder lock is fixed to the mounting plate, and a cam is attached to the lock shaft of the cylinder lock. A locking device for a game machine in which a member is attached to be able to engage with the operating rod, an attachment plate of the base frame is attached to the inside of the front door of the game machine, and a support is attached to the inside of the cabinet of the game machine There,

The latch members are pivotally supported in the vicinity of the recesses of the opening, and the latch members are locked at the latch positions when the latch members are pushed by the receiving members and rotated to the latch position when the front door is closed. When the cam member is rotated in the unlocking direction of the latch member by the cylinder lock, the operating rod moves, the locking is released, and the latch member rotates to the unlocking side. In
The operating rod is provided with a locking engagement portion, a second cylinder lock is attached to a part of the base frame body, and is locked by the locking engagement portion at the time of locking in the unlocking direction of the operating rod. A lock member that prevents the movement of the cam member and the engagement between the cam member and the operating rod is fixed to the lock shaft of the second cylinder lock.

  According to the locking device of the present invention, when unlocking, first, the lock member is rotated by operating the second cylinder lock to release the lock member from the lock engagement portion of the operating rod. Next, when the key of the cylinder lock is rotated in the unlocking direction and the cam member rotates in the same direction, the operating rod engaged therewith moves, and the operating engagement portion acts on the locking pin of the latch member. move. As a result, the locking pin is disengaged from the lock portion of the guide locking hole of the support plate. At this time, the latch member is rotated to the unlocking side by the urging force of the spring member, and the locked receiver is moved to the latch member. It comes out of the latch recess and is pushed out of the opening recess to be unlocked.

  In the locked state, since the lock member is locked by the locking engagement portion of the operating rod and the movement of the operating rod in the unlocking direction is locked, an unauthorized device such as a wire can be removed from the gap of the front door. Even if it is inserted and hooked on the operating rod and moved in the unlocking direction, it is impossible to prevent unauthorized unlocking due to movement of the operating rod.

  According to a second aspect of the present invention, in the locking device according to the first aspect, a non-contact function switch is attached to the base frame body, and a switch operation for operating the function switch on a part of the operating rod. When the cylinder lock is rotated in the direction opposite to the unlocking direction, the operating rod moves in the direction opposite to the unlocking direction, and the switch operating unit operates the function switch. The lock member is provided with an opening through which the cam member can enter, and the cam member prevents the movement of the operating rod toward the unlocking side. The operating rod enters the opening of the operating rod, and the operating rod can be moved only in the switch operating direction.

  According to the present invention, when operating the function switch, when the key of the cylinder lock is turned in the opposite direction to the unlocking direction, the cam member rotates in the same direction, and the operating rod moves by engaging with the cam member. As a result, the switch actuating portion provided on the operating rod acts on the function switch, the function switch performs a switching operation, and the game machine is reset.

  Therefore, since the operating rod is used both for unlocking and for operating the switch, the switch operating rod used in the conventional locking device is not required, the number of parts can be reduced, and the assembling work can be simplified. Moreover, even if the operating rod is a dual purpose, when the cylinder lock is turned in the reverse direction with the locking member locking the movement of the operating rod in the unlocking direction, the operating rod is moved only in the switch operating direction. Switching operation can be performed.

  According to the locking device for a game machine of the present invention, it is possible to prevent unauthorized unlocking by improperly moving the operating rod, and even when a function switch that functions in accordance with the operation of the cylinder lock is provided, The number of parts can be reduced by eliminating the need for operating rods.

Further, the side support plate of the widened portion 2a is divided and formed as a divided support plate 3a, and a support roller 22 is rotatably supported on the lower portion of the divided support plate 3a.

  Opening recesses 3b and 3c are formed on the back side of the upper and lower portions of the support plate 3 so as to cut out part of the support plate 3, and latched at positions just below the upper and lower opening recesses 3b and 3c, respectively. The members 10 and 10 are pivotally supported by pivots 5 and 5 so as to be rotatable within a predetermined angle range. When the latch members 10 and 10 are locked, the locking portions 33 and 34 of the receiving tool 31 enter the opening recesses 3b and 3c, and the latch member 10 pivotally supported at a position directly below the opening recesses 3b and 3c is locked. The cylindrical portion 41 of the portions 33 and 34 is rotated while being received in the latch recess 15, and the locking portions 33 and 34 are restrained. Further, as shown in FIG. 4, guide locking holes 8 and 8 for guiding and locking the locking pins 14 on the latch member 10 side are respectively provided slightly below the upper and lower opening recesses 3b and 3c. 3 is formed.

  The guide locking holes 8 and 8 are formed in a substantially L shape as shown in FIG. 4, and portions parallel to the support plate 3 are formed as lock portions 8a and 8a, and the locking pins 14 of the latch members 10 and 10 are formed. When the guide holes 12a and 12a of the cover plate 12 are moved and simultaneously enter the lock portions 8a and 8a from the guide locking holes 8 and 8, the latch member 10 is latched and locked.

  Further, support protrusions 9 and 9 are provided on the support plate 3 slightly above the upper and lower guide locking holes 8 and 8 so as to protrude inward, that is, toward the latch members 10 and 10, respectively. As shown in FIG. 6 b, the support protrusions 9, 9 enter an arcuate engagement recess 12 b formed on the inner surface of the latch member 10 and abut against the spring member 13. As a result, the latch member 10 rotates against the biasing force of the spring member 13 during locking as shown in FIG. 14, and the locking pin 14 moves from the lock portion 8a to the guide locking hole 8 when unlocked. When released, the latch member 10 is rotated in the unlocking direction by the biasing force of the spring member 13.

  As shown in FIG. 6, the latch member 10 is formed with a groove-shaped latch recess 15 that receives and restrains the locking portions 33 and 34 of the receiving member 31, and the latch member 10 further includes a latch member 10. A latch pin 14 and a spring member 13 for energizing are latched. Further, as shown in FIG. 6, the latch member 10 is formed having a latch body 11 and a cover plate 12 covering the latch body 11. A space is formed in the latch body 11, and a spring member 13 is formed in the internal space. The locking pin 14 is stored.

  The latch body 11 is molded using a hard synthetic resin having high wear resistance such as polyacetal resin or polyamide resin, and the cover plate 12 is formed of a metal plate for reinforcement. A lubricant such as molybdenum disulfide is added to the molding material for molding the latch body 11, and thereby, the latch body 11 that forms the outer surface of the latch member 10 has an appropriate slipperiness, so The cylindrical portion 41 of the locking portions 33 and 34 is smoothly inserted. Further, the strength of the latch member 10 is reinforced by fixing a metal plate cover plate 12 to the inner side surface of the latch body 11 with a fixing screw 12a. Further, the cover plate 12 is provided with a locking piece 12d at the end, and the locking piece 12d is inserted into a slit provided in the latch main body 11 to be locked, and can be fixed with a single fixing screw 12c. .

  When the latch member 10 is rotated to the latch position, the latch pin 14 built in the latch member 10 is locked by being locked to the lock portion 8a of the guide latch hole 8 of the support plate 3 at that position. Thus, it is arranged so as to protrude from the guide hole 12 a formed in the cover plate 12 toward the support plate 3, and is always urged outward by the spring member 13.

  As shown in FIG. 6, the spring member 13 is a torsion spring having two circular coil portions. One of the circular coil portions 13a is fitted to the pivot boss portion of the latch body 11, and the other circular coil portion 13b. Is fitted to a latching boss 11a projecting at a biased position in the latch body 11, and the latching pin 14 is urged at one end of the spring member 13, and the other end projects inside the support plate 3. It is latched so that the provided support convex part 9 may be urged | biased. The support convex portion 9 on the support plate 3 side enters and engages with the arc-shaped engagement concave portion 12 b formed on the cover plate 12 of the latch member 10, and the other end of the spring member 13 in the latch member 10 is engaged. The support projection 9 is engaged. That is, when the other end of the spring member 13 is engaged with the support protrusion 9, the latch member 10 is biased by receiving a spring force relatively to the unlocking side (clockwise in FIG. 15).

  As shown in FIG. 6, the latch member 10 is unitized with a spring member 13 and a locking pin 14 incorporated therein, and the locking pin 14 and the spring member 13 are incorporated into the latch body 11 to fix the cover plate 12. It can be fixed in advance with screws 12c and pre-manufactured prior to the assembly process of the locking device. Thereby, in the production line of the locking device, it is only necessary to pivotally support the latch member 10 with the pivot 5, and the assembling work is simplified.

  A vertically long and belt-like operating rod 4 is slidably disposed along the outside of the support plate 3 of the base frame body 1 and the inside of the divided support plate 3a. As shown in FIG. 4, operation engagement portions 4 a and 4 b are provided on the operation rod 4 at the upper and lower portions thereof so as to project toward the support plate 3 and toward the latch member 10. Further, the operation engaging portions 4a and 4b are located in the vicinity of the lock portions 8a and 8a of the guide locking holes 8 and 8 in which the locking pins 14 and 14 of the latch members 10 and 10 are disposed, and are unlocked. In some cases, the locking pins 14 and 14 in the lock portions 8a and 8a are pushed by the tips of the operation engagement portions 4a and 4b to release the lock. The operation engagement portions 4a and 4b are arranged inside the operation rod 4 and the outside thereof is covered with a metal plate, and slightly protrude outside the support plate 3 through the guide locking holes 8 and 8. This is a structure that acts on the tips of the locking pins 14, 14.

  In addition, the operating rod 4 is formed with engaging holes 4c, 4d for engaging a cam member 21 described later at the upper part corresponding to the engaging holes 4c, 4d. Furthermore, guide holes 4g and 4g are formed immediately below the operation engagement portions 4a and 4b of the operating rod 4, and the guide pins 6 and 6 are inserted into the guide holes 4g and 4g and fixed to the support plate 3. Thus, the vertical sliding of the operating rod 4 is guided by the guide pins 6 and 6.

  The operating rod 4 is disposed along the outside of the support plate 3 and along the inside of the divided support plate 3a, and the operating rod 4 is supported in a floating state by a single spring member (coil spring) 16. . Thereby, when the operating rod 4 moves up or down by the movement of the cam member 21, the operating rod 4 can return to the neutral position under the urging force of the spring member 16.

  Specifically, as shown in FIG. 4, guide pins 16 c and 16 d are inserted from the inside of the support plate 3 through guide holes 3 d and 3 e provided in the support plate 3. Further, guide pins 16c and 16d are inserted into the guide holes 4f and 4e of the operating rod 4 positioned outside the support plate 3, and spring-hanging members 16a and 16b are respectively protruded from the tips protruding outside the operating rod 4. The spring member 16 is hung between the spring hook members 16a and 16b on both sides. Accordingly, the operating rod 4 can move upward and downward from the neutral position in FIG. 8 against the urging force of the spring member 16, and the operating rod 4 is moved upward by the rotating operation of the cam member 21 by the cylinder lock 7. Or when it moves below, it has a structure which returns to a neutral position by the loss | disappearance of a moving force.

  The operating rod 4 is used both for unlocking operation and for switching operation, and a switch operating portion 4e is provided near the lower portion of the operating rod 4. On the other hand, when the function switch (photoelectric non-contact switch) 17 is attached to the place of the support plate 3 corresponding to the switch operating portion 4e and the operating rod 4 is lowered, the switch operating portion 4e acts on the function switch 17. Then, the function switch 17 is switched. This function switch 17 is used to reset the game machine.

  In this way, by using the unlocking operation rod 4 for both unlocking operation and switch operation, the conventionally required operation rod for the operation switch and the coil spring for biasing it are unnecessary, The number of parts can be reduced and the structure of the locking device can be simplified.

  As shown in FIG. 5, a large-diameter hole is formed in the widened portion 2a at the top of the mounting plate 2 of the base frame body 1, and the cylinder lock 7 is mounted in such a manner that the large-diameter hole is inserted from the inside. The cylinder lock 7 has a flange 7 a and is fixed by screwing the flange 7 a to the widened portion 2 a of the mounting plate 2. The lock shaft of the cylinder lock 7 protrudes to the inside of the base frame body 1, and the cam member 21 is fixed to the tip thereof. The cam member 21 is formed with a first engaging convex portion 21a and a second engaging convex portion 21b, and the first engaging convex portion 21a is actuated according to the clockwise rotation of the key of the cylinder lock 7. The second engagement protrusion 21b engages with the engagement hole 4c of the operating rod 4 according to the left rotation.

  Therefore, when the key of the cylinder lock 7 is turned to the right, the cam member 21 is rotated in the same direction, and the engagement convex portion 21a of the cam member 21 is engaged with the engagement hole 4d of the operating rod 4, and the spring member. The operating rod 4 is lifted against the urging force of 16, and the locking pins 14 of the latch members 10 and 10 are pushed up by the operating engagement portions 4a and 4b to unlock the latch members 10 and 10. On the other hand, when the key of the cylinder lock 7 is turned counterclockwise, the cam member 21 rotates in the same direction, the engagement convex portion 21b of the cam member 21 engages with the engagement hole 4c, and the biasing force of the spring member 16 The actuating rod 4 is lowered against this, and the switch actuating portion 4e enters the function switch 17 to switch the function switch.

  Further, a second cylinder lock 19 is mounted on the back side of the mounting plate 2 in the upper part of the base frame body 1. A lock member 18 is fixed to the lock shaft of the second cylinder lock 19, and the distal end portion of the lock member 18 is located inside the base frame 1 from a slit 2 c (FIG. 5) provided in the widened portion 2 a of the mounting plate 2. It enters and is inserted between the cam member 21 and the operating rod 4 to prevent the operating rod 4 from moving in the unlocking direction due to the rotation of the cam member 21.

  The operating rod 4 is prevented from moving to the unlocking side (upward) by the lock member 18 of the second cylinder lock 19, but to enable the operating rod 4 to move in the switch operating direction (downward). In addition, the lock member 18 is formed with an opening 18a into which the engaging projection 21b can enter when the cam member 21 rotates in the switch operating direction. Thus, even when the second cylinder lock 19 is in the locked state, the cam member 21 can be rotated in the switch operating direction, and the operating rod 4 can also be moved downward.

  Further, when the lock member 18 is in the locked position as shown in FIGS. 1 and 2, the lock member 18 is brought into contact with the locking engagement portion 4 h protruding from the corresponding position of the operating rod 4 to unlock the operating rod 4. Stop moving in the direction. Thereby, the movement in the unlocking direction of the operating rod 4 in the locked state is locked, and unauthorized unlocking by a wire or the like is prevented. That is, as shown in FIGS. 4 and 5, the locking engagement portion 4 h protrudes inwardly at a position near the lock member 18 in the operating rod 4. When the lock member 18 fixed to the lock shaft of the second cylinder lock 19 is in the locked state in which the lock member 18 is rotated to the cam member 21 side by the lock operation of the second cylinder lock 19 as shown in FIG. The portion comes into contact with the locking engagement portion 4h to prevent the operating rod 4 from sliding upward.

  As described above, the second cylinder lock 19 has a function of double-locking the locking device together with the cylinder lock 7, and locks the unlocking operation of the cylinder lock 7. Therefore, at the time of unlocking, after the unlocking operation is performed with the key of the second cylinder lock 19, the cylinder lock 7 is further unlocked and unlocked to further improve the security. The second cylinder lock 19 is fixed to a mounting seat 2b projecting from the upper back side of the mounting plate 2, and the keyhole of the second cylinder lock 19 is arranged facing the right side surface of the locking device body. When the device is attached to the front door 51 of the game machine, the keyhole appears on the right side surface of the front door 51 so as not to stand out from the front side of the game machine.

When the latch members 10 and 10 are pivoted to the pivot end, the latch pin 14 in the latch member 10 is moved in the guide latch hole 8 by the biasing force of the spring member 13, thereby The locking pin 14 enters the lock portion 8 a of the guide locking hole 8.

  At this time, the rotation of the latch members 10 and 10 is locked, and as shown in the left end view of FIG. 14, the locking portions 33 and 34 of the receiver 31 are restrained in the latch recesses 15 and 15 of the latch members 10 and 10. Then, the latch members 10 and 10 are held at the latch position, and the locked state as shown in FIG. 12 is obtained. At the time of such locking, as described above, the cylindrical recessed portion 15 of the latch member 10 and the cylindrical portion 41 of the synthetic resin covering portion 40 of the receiving member 31 inserted therein are made of a synthetic resin having appropriate lubricity. Since it is molded, it can be locked very smoothly and the unlocking operation can be performed smoothly. In addition, the use of the synthetic resin latch member 10 and the receiver 31 with good wear resistance reduces wear at the contact and contact points, and allows the latch member and the receiver to operate stably over a long period of time. Can do.

  And after closing the front door 51 as mentioned above and making it a locked state, a key is further inserted in the 2nd cylinder lock 19, and it locks by turning to the right. By this operation, the lock member 18 rotates clockwise from the state of FIG. 12 as shown in FIG. 13 and enters between the cam member 21 and the operating rod 4, and the engagement convex portion 21 a of the cam member 21 The engagement of the engagement hole 4d of the operating rod 4 is made impossible. At this time, the tip of the lock member 18 comes into contact with the locking engagement portion 4h of the operating rod 4, and the upward movement of the operating rod 4 (movement toward the unlocking side) is prevented. Therefore, in the locked state shown in FIG. 13, even if the operating rod 4 is moved to the unlocking side with a wire or the like, it becomes impossible, and the cam member 21 is unlocked by temporarily turning the lock shaft of the cylinder lock 7. Even if the cam member 21 is rotated in the direction, the cam member 21 is prevented from rotating and unauthorized unlocking is prevented.

  On the other hand, when switching the function switch 17 in order to reset the game machine or the like, a key is inserted into the cylinder lock 7 and turned to the left. As shown in FIG. 7, since the lock member 18 is provided with an opening 18a, when the key inserted into the cylinder lock 7 is turned counterclockwise, the cam member 21 is rotated in the same direction and engaged therewith. The convex portion 21b enters from the opening 18a and engages with the engagement hole 4c of the operating rod 4, and the operating rod 4 moves downward. As a result, the switch operating portion 4 e of the operating rod 4 acts on the function switch 17. Therefore, even in the locked state, the function switch 17 can be switched by moving the operating rod 4 downward.

  When unlocking the front door 51, first, a key is inserted into the second cylinder lock 19 and turned, and the lock member 18 of the lock shaft is turned counterclockwise in FIGS. Is allowed to rotate (rotation counterclockwise in FIG. 3). Next, when a key is inserted into the cylinder lock 7 and the key is turned clockwise, the cam member 21 rotates in the same direction, and the engagement convex portion 21a of the cam member 21 engages with the engagement hole 4d of the operating rod 4. The operating rod 4 moves upward. As a result, the upper and lower operation engaging portions 4a and 4b of the operating rod 4 (located facing the lock portion 8a of the guide locking hole 8 of the support plate 3) similarly move upward, and the lock portion As shown in FIG. 15, the locking pin 14 in 8a acts to push upward.

  At this time, as shown in FIG. 15, the locking pin 14 is moved from the lock portion 8a to the guide locking hole 8 by the urging force of the spring member 13, and the latch members 10 and 10 are locked at the latch position. Come off. That is, the latch members 10 and 0 are rotated in the clockwise direction in FIG. 15 by the biasing force of the spring member 13, and the cylindrical portion of the synthetic resin covering portion 40 of the locking portions 33 and 34 of the receiving member 31 that has been restrained. 41 is disengaged from the latch recesses 15, 15 of the latch members 10, 10, and is also pushed out from the opening recesses 3 b, 3 c to be unlocked.

  As described above, when the locking device is locked, the lock member 18 is locked to the locking locking portion 4h of the operating rod 4 and the movement of the operating rod 4 in the unlocking direction is locked. It is impossible to insert a fraudulent instrument such as a wire through the gap 51 and hook it on the operating rod to move it in the unlocking direction, and it is possible to prevent unauthorized unlocking due to the movement of the operating rod 4.

  Further, when the key of the cylinder lock 7 is turned in the opposite direction to the unlocking time, the cam member 21 rotates in the same direction, and the operating rod 4 engaged therewith moves in the opposite direction to the unlocking time, Since the switch operating portion 4e provided in the operating rod 4 acts on the function switch 17, and the function switch 17 performs a switching operation, the operating rod 4 is used both for unlocking and for operating the switch. For this reason, the switch operating rod used in the conventional locking device becomes unnecessary, the number of parts can be reduced, and the assembling work can be simplified.

  In addition, the operating rod 4 spans one spring member (coil spring) 16 between a pair of moving members (spring hanging members 16a and 16b), and the pair of moving members (spring hanging members 16a and 16b) A structure in which the operating rod 4 is engaged with each guide hole formed in the support plate 3 of the base frame 1 so as to be movable up and down, and the spring member 16 supports the operating rod 4 in a floating state in both the up and down directions. Therefore, the operating rod 4 can be moved against a biasing force in both the upper and lower directions by a single coil spring, and the number of parts such as spring members can be reduced to simplify the structure.
