Description

  The present invention is used to lock a front frame to an outer frame when the front frame is closed in a gaming machine such as a pachinko gaming machine or a pachislot machine that supports the front frame so that it can be opened and closed. The present invention relates to a locking device.

  Conventionally, a locking device for locking a front frame to an outer frame is incorporated in a gaming machine such as a pachinko gaming machine. As a locking device, a device including a frame, a pair of upper and lower flange members, a connecting rod, a cylinder lock, and a cam plate is well known. The frame is attached to the front frame, and both flange members are supported by shafts at both upper and lower ends of the frame. Each saddle member tilts about a shaft as a fulcrum, and thereby latches and disengages from a receiving metal fitting fixed to the outer frame. The connecting rod is disposed on the frame body so as to be able to reciprocate in the vertical direction, and the upper and lower ends of the connecting rod are connected to the flange member. The cylinder lock is incorporated in the frame, and a key is inserted and unlocked when unlocking. The cam plate is attached to the lock shaft of the cylinder lock, transmits the rotation of the lock shaft accompanying the operation of the key to the connecting rod, and moves the connecting rod downward.

  According to the locking device described above, at the time of locking, the connecting rod is positioned above and the both flange members are locked to the receiving metal fitting. When the key is rotated in a predetermined direction, the rotation of the lock shaft is transmitted to the connecting rod through the cam plate. Due to the downward movement of the connecting rod, the upper and lower flange members are simultaneously tilted and detached from the metal fittings, respectively, and unlocked. Thus, the locking device is designed to be unlocked when the key is inserted into the cylinder lock and turned.

  By the way, in the pachinko hall sima, a large number of pachinko gaming machines are arranged side by side, and ball lending machines are arranged between adjacent pachinko gaming machines. In order to install this ball lending machine, adjacent pachinko machines are usually arranged at a slightly wider interval than the width of the ball lending machine. Along with this, there is a slight gap between the pachinko gaming machine and the ball lending machine. Therefore, it is possible to insert a wire such as a wire through the gap and apply a force directly to the eaves member, particularly the lower eaves member. When one (lower) collar member is tilted in this way, the movement is also transmitted to the other (upper) collar member via the connecting collar, and the upper and lower collar members are tilted and received together. Detach from the bracket. Originally, there is a problem that a locking device that cannot be unlocked without using a dedicated key is illegally unlocked without using the key.

  Then, this invention makes it a subject to provide the locking device of the game machine which can prevent the illegal unlocking which moves a collar member illegally with a wire etc. and unlocks it reliably.

  The invention according to claim 1 is a lock provided on a front frame of a gaming machine and operated to be unlocked by a key, and a plurality of objects provided on the front frame and provided on an outer frame of the gaming machine. A plurality of scissors members including at least a first scissors member and a second scissors member, which are respectively locked and detached from the locking portions, and the operation of the lock according to the unlocking operation of the key are transmitted to all the scissors members. And the unlocking transmission mechanism for releasing from the locked portion, and the operation of the first scissors member according to the unlocking operation on the first scissors member is transmitted to at least one of the scissors members that are not unlocked. And a first transmission blocking mechanism for blocking the transmission.

  According to the above invention, at the time of locking, all the hook members are locked to the locked portions, and the front frame of the gaming machine is kept closed. When the key is unlocked, the lock operates according to the operation. The operation of the lock is transmitted to all the hook members through the key unlocking transmission mechanism, the hook members are detached from the locked portions, and the front frame can be opened. On the other hand, when an unauthorized unlocking operation is performed on the first rod member with a wire or the like without using a key, the rod member is detached (disengaged) from the locked portion. However, the operation of the first hook member is not transmitted to at least one of the hook members that are not unlocked due to the action of the first transmission blocking mechanism. As a result, the at least one flange member continues to maintain the state of being locked to the locked portion, and the front frame does not open.

  As described above, according to the present invention, even when an unauthorized unlocking operation is performed on a predetermined hook member with a wire or the like, other hook members are prevented from being interlocked and detached from the locked portion. Can do. Unauthorized opening of the front frame can be prevented beforehand.

(First embodiment)
Hereinafter, a first embodiment in which the present invention is embodied in a locking device for a pachinko gaming machine will be described with reference to the drawings. As shown in FIGS. 1 and 2, the pachinko gaming machine 1 includes an outer frame 2, a front frame (sometimes referred to as an inner frame) 3 that is supported by the shaft 9 so as to be opened and closed, and a front frame. 3 and a glass frame 5 supported by a front frame 3 so as to be opened and closed by a shaft 10. A locked portion is fixed to the right side in the outer frame 2. The locked portion is made of a highly rigid material such as a metal plate. Here, a bent metal plate (hereinafter referred to as “receiving metal fitting”) is used as the locked portion, and this is fixed to the outer frame 2 with a wood screw or the like. There are a plurality (two or more) of receiving brackets, and here two receiving brackets (first receiving bracket 6 and second receiving bracket 7) are used. The first metal fitting 6 is fixed to the lower part of the outer frame 2, and the second metal fitting 7 is fixed to the upper part of the outer frame 2. A vertically long locking device 8 is assembled on the right side of the back surface of the front frame 3. The locking device 8 includes a mechanism for locking the front frame 3 to the outer frame 2 when the front frame 3 is closed, and the glass frame 5 to the front frame 3 when the glass frame 5 is closed. And a mechanism for stopping. In the present embodiment, the former mechanism is mainly described, and the description of the latter mechanism is omitted.

  As shown in FIGS. 3 (a) and 3 (b), the locking device 8 includes a vertically elongated frame 13, and the frame 13 is fixed to the front frame 3. Here, a metal plate bent at a substantially right angle to form an angle is used as the frame 13, but the present invention is not limited to this. In order to distinguish two plate-like portions that are substantially orthogonal to each other in the frame 13, one is referred to as an “attachment portion 11” and the other is referred to as a “support portion 12”. The attachment portion 11 is fixed to the back surface of the front frame 3 by a fastener such as a wood screw, and the support portion 12 is substantially orthogonal to the back surface. An auxiliary frame 35 is attached to the upper portion of the frame 13 so as to be reciprocable in the vertical direction. The auxiliary frame 35 forms a part of a mechanism for locking the glass frame 5 to the front frame 3.

  As shown in FIG. 4B, a lock that is unlocked by a dedicated key (hereinafter referred to as “dedicated key”) 14 for unlocking is attached to the attachment portion 11. Here, the cylinder lock 15 is used as the lock, but other types of locks may be used. In the cylinder lock 15, the dedicated key 14 is inserted and rotated for unlocking, but here, in the clockwise direction when viewed from the front of the pachinko gaming machine 1 (the direction indicated by the arrow in FIG. 4B). ) Is a direction in which the dedicated key 14 is turned when the front frame 3 is opened, and the counterclockwise direction is a direction in which the dedicated key 14 is turned when the glass frame 5 is opened. The cylinder lock 15 is passed through a hole (not shown) formed in the front frame 3. As shown in FIGS. 3A and 3B, the cylinder lock 15 includes a lock shaft 16 that rotates as the dedicated key 14 is operated. A cam plate 19 having a first protrusion 17 and a second protrusion 18 is attached to the lock shaft 16.

  In the lower part of the support portion 12, a first flange member 21 is supported by a shaft 22 so as to be tiltable in the vertical direction at a position corresponding to the first receiving metal fitting 6. The first collar member 21 is locked to the first metal fitting 6 when being in a substantially horizontal state, and is detached (disengaged) from the metal fitting 6 when tilted downward. Similarly, in the upper part of the support portion 12, the second flange member 23 is supported by a shaft 24 so as to be tiltable in the vertical direction at a position corresponding to the second metal fitting 7. The second flange member 23 is locked to the second metal fitting 7 when it is in a substantially horizontal state, and is detached (disengaged) from the metal fitting 7 when tilted downward. In addition, as the eaves members 21 and 23, a type that detaches from the receiving metal fittings 6 and 7 when tilted upward may be used, or the operation other than the tilting may be performed to engage and release the receiving metal fittings 6 and 7. The type to be used may be used.

  In the vicinity of the side of the support portion 12 (left side in FIG. 3A), a connecting rod 20 is disposed so as to be capable of reciprocating in the vertical direction. The frame 13 is provided with a mechanism for restricting movement of the connecting rod 20 in the front-rear direction and in the left-right direction. In FIG. 3A, the front-rear direction is indicated by an arrow X, and the left-right direction is indicated by an arrow Y. As a mechanism for regulating the movement in the front-rear direction, a predetermined number of guide pieces 27 are bent at the rear portion of the support portion 12, and the connecting rod 20 is sandwiched between the guide pieces 27 and the attachment portion 11. As a mechanism for restricting the movement in the left-right direction, a predetermined number of restricting projections 28 are formed on the back surface of the mounting portion 11, and the connecting rod 20 is sandwiched between the restricting projections 28 and the support portion 12. These regulation mechanisms are merely examples, and can be changed as appropriate. Of the reciprocating movement of the connecting rod 20 in the vertical direction, the upward movement is related to unlocking. As will be described later, when the connecting rod 20 is moved upward, all the collar members 21 and 23 are detached from the receiving brackets 6 and 7 and unlocked. For this reason, “upward” in the vertical direction that is the reciprocating direction of the connecting rod 20 is referred to as “unlocking direction”.

  The connecting rod 20 is divided into a first connecting rod 25 and a second connecting rod 26 arranged on the upper side thereof. The first connecting rod 25 has a vertically elongated shape, and is connected to the first flange member 21 at its lower end portion so that power can be transmitted. Here, the lower end portion of the first connecting rod 25 is directly connected to the first flange member 21 by the connecting pin 29. Therefore, both power transmission from the first connecting rod 25 to the first rod member 21 and power transmission in the opposite direction are possible.

  The second connecting rod 26 has a vertically elongated shape, and a rotation transmission portion 32 with which the first protrusion 17 that does not rotate the cam plate 19 is abutted is formed at a part thereof. The cam plate 19 and the rotation transmission unit 32 convert the rotational motion of the lock shaft 16 into a linear motion and transmit it to the second connecting rod 26. When the dedicated key 14 is rotated in the clockwise direction to open the front frame 3, the first protrusion 17 comes into contact with the rotation transmitting portion 32 from below and pushes up the second connecting rod 26. In this way, the second connecting rod 26 moves in the unlocking direction as the dedicated key 14 is unlocked. On the contrary, when the dedicated key 14 is turned counterclockwise to open the glass frame 5, the second protrusion 18 pushes down the auxiliary frame 35.

  The upper end portion of the second connecting rod 26 is connected to the second flange member 23 so that power can be transmitted. However, unlike the lower end part of the 1st connecting rod 25 mentioned above, the upper end part is not connected with the 2nd flange member 23 by the connecting pin. Instead of the connection by the connection pin, a pressing portion 33 is provided at the upper end portion of the second connection rod 26, and a pressure receiving portion 34 is provided at the second flange member 23. Here, the upper end edge of the second connecting rod 26 is used as the pressing portion 33. A part of the second rod member 23 is bent toward the second connecting rod 26, and the bent portion serves as a pressure receiving portion 34. The pressing portion 33 and the pressure receiving portion 34 are merely examples. When the second connecting rod 26 is moved upward (unlocking direction) by the operation of the dedicated key 14, the pressure receiving portion 34 contacts the pressing portion 33, and As long as the condition that the pressure receiving portion 34 is separated from the pressing portion 33 is satisfied when the first collar member 21 is improperly pressed, it can be changed as appropriate. In this change, the pressing portion 33 may be formed integrally with the second connecting rod 26, or may be formed by a separate member and fixed to the second connecting rod 26 by means such as adhesion or welding. The same applies to the pressure receiving unit 34.

  Further, a second elastic member that urges the second flange member 23 in a direction in which the pressure receiving portion 34 is brought into contact with the pressing portion 33 is used. Here, the second coil spring 36 is used as the second elastic member, and is stretched between the auxiliary frame 35 and the pressure receiving portion 34 in a tensioned state. The second coil spring 36 may be hooked on the frame body 13 instead of the auxiliary frame 35. As the second elastic member, a spring such as a compression coil spring, a torsion coil spring, a leaf spring, or a bar spring may be used, or a material other than the spring, for example, rubber (rubber string or the like) may be used.

  The 1st connection rod 25 and the 2nd connection rod 26 are connected so that expansion and contraction is possible as follows. One of the connecting rods 25 and 26 is provided with a guide portion extending along the length direction thereof, and the other is provided with an engagement protrusion, and the engagement protrusion is reciprocally inserted into the guide portion. Has been. Here, an elongated hole 37 that is elongated in the vertical direction is formed in the lower end portion of the second connecting rod 26 as a guide portion. An engaging pin 38 is fixed to the upper end of the first connecting rod 25 as an engaging protrusion. The engaging pin 38 is engaged in the long hole 37. Therefore, when the engagement pin 38 is slid in the long hole 37, the connecting rod 20 expands and contracts.

  Contrary to the above, the guide portion may be provided on the first connecting rod 25 and the engaging protrusion may be provided on the second connecting rod 26. Moreover, as a guide part, not only a long hole but a groove | channel may be sufficient. Furthermore, the 1st elastic member which always urges | biases the 1st connecting rod 25 to the downward direction (anti-unlocking direction) is provided. Here, the first coil spring 31 is used as the first elastic member, and is stretched over the attachment portion 11 and the first connecting rod 25 in a state in which the first coil spring 31 is pulled. As the first elastic member, a spring such as a compression coil spring, a torsion coil spring, a leaf spring, or a bar spring may be used, or a member other than the spring, for example, rubber may be used.

  And the 1st connection rod 25, the 2nd connection rod 26 which has the rotation transmission part 32, the long hole 37 and the engagement pin 38 which connect both connection rods 25 and 26 so that expansion-contraction is possible, and the 1st connection rod 25 A connecting pin 29 that connects to the first flange member 21, a pressing portion 33 and a pressure receiving portion 34 that connect the second connecting rod 26 to the second flange member 23 so that power can be transmitted, and a first coil spring 31 and a second coil spring. 36 constitutes a key unlock transmission mechanism A, a first transmission blocking mechanism B, and a second transmission blocking mechanism C. These components function as the key unlocking transmission mechanism A, thereby transmitting the operation of the cylinder lock 15 according to the unlocking operation of the dedicated key 14 to all the flange members 21 and 23 and receiving brackets 6 and 7. To be removed. By functioning as the first transmission blocking mechanism B, the movement of the coffin member 21 in response to the unlocking operation on the first coffin member 21 is blocked from being transmitted to the second coffin member 23 that has not been unlocked. To do. By functioning as the second transmission blocking mechanism C, the movement of the coffin member 23 in response to the unlocking operation on the second coffin member 23 is blocked from being transmitted to the first coffin member 21 that has not been unlocked. To do.

  Among the components of the key unlocking transmission mechanism A and the first transmission blocking mechanism B, the long hole 37, the engagement pin 38 and the first coil spring 31 are the power from the second connection rod 26 to the first connection rod 25. A first transmission path interrupting portion D for allowing transmission and blocking power transmission from the first connecting rod 25 to the second connecting rod 26 is configured. Among the components of the key unlock transmission mechanism A and the second transmission cutoff mechanism C, the pressing portion 33, the pressure receiving portion 34, and the second coil spring 36 allow power transmission from the connecting rod 20 to the second flange member 23, A second transmission path intermittent portion E for interrupting power transmission from the second flange member 23 to the connecting rod 20 is configured.

  The pachinko gaming machine 1 to which the locking device 8 is assembled is arranged in a horizontal row in the pachinko hall. As shown in FIG. 1, a vertically long ball lending machine 41 is arranged between adjacent pachinko gaming machines 1 as indicated by a two-dot chain line.

  Next, the operation and effect of the present embodiment configured as described above will be described. FIG. 4A shows a state when the locking device 8 is locked. In this state, the second flange member 23 pulled downward by the second coil spring 36 is engaged with the second metal fitting 7 from below. The upward movement of the second connecting rod 26 is restricted by the pressure receiving portion 34. Further, the first protrusion 17 is in contact with the rotation transmitting portion 32 from below. For this reason, the 2nd connecting rod 26 cannot move up and down. In the first connecting rod 25, the downward pulling force by the first coil spring 31 is always acting, but the engaging pin 38 is in contact with the lower end of the long hole 37, and this contact makes the first connection The downward movement of the collar 25 is restricted. And the 1st collar member 21 connected with the lower end of the 1st coupling rod 25 is latched to the 1st metal fitting 6 from the lower side. The front frame 3 is kept in a closed state by the locking of the two flange members 21 and 23.

  In order to open the front frame 3, as shown in FIGS. 4B and 4C, when the dedicated key 14 is inserted into the cylinder lock 15 and turned in the direction indicated by the arrow in FIG. And the cam plate 19 rotates in the same direction. As the cam plate 19 rotates, the first protrusion 17 pushes up the second connecting rod 26 through the rotation transmitting portion 32. The movement of the second connecting rod 26 is transmitted to the second flange member 23 by the second transmission path intermittent portion E. Specifically, the movement of the second connecting rod 26 is transmitted to the second flange member 23 through the pressing portion 33 and the pressure receiving portion 34. The second flange member 23 tilts downward against the tensile force of the second coil spring 36 and is detached from the second metal fitting 7. Further, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 by the first transmission path intermittent portion D. Specifically, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 through the engaging pin 38 positioned at the lower end of the long hole 37. The first connecting rod 25 is integrated with the second connecting rod 26 and moves upward against the tensile force of the first coil spring 31. This movement is transmitted to the first flange member 21 through the connecting pin 29, and the flange member 21 tilts downward and is detached from the first metal fitting 6. In this way, the cylinder lock 15 operates in response to the unlocking operation of the dedicated key 14, and the operation is performed by the action of the key unlocking transmission mechanism A, the first transmission path intermittent portion D, and the second transmission path intermittent portion E. It is transmitted to all the eaves members 21 and 23. The flange members 21 and 23 are removed from the metal fittings 6 and 7 almost simultaneously, and the front frame 3 can be opened.

  On the other hand, using the fact that a slight gap is generated between the pachinko gaming machine 1 and the ball lending machine 41, a wire rod such as a wire is inserted through the lower portion of the gap without using the dedicated key 14, and FIG. As shown in a), when a force is directly applied to the first flange member 21 and tilted downward, the first flange member 21 is detached from the first metal fitting 6. However, the operation of the first rod member 21 is not transmitted to the second rod member 23 that has not been unlocked due to the action of the first transmission blocking mechanism B and the first transmission path intermittent portion D. Specifically, the first connecting rod 25 moves upward (unlocking direction) against the first coil spring 31 by the tilting of the first flange member 21. As a result, the engaging pin 38 moves upward from the lower end of the long hole 37. By this movement, power transmission from the first connecting rod 25 to the second connecting rod 26 is interrupted. Although the first connecting rod 25 moves, the second connecting rod 26 does not move, and as a result, the second flange member 23 continues to be locked to the second metal fitting 7. The front frame 3 remains closed.

  Contrary to the above, a wire rod or the like is inserted through the upper part of the gap between the pachinko gaming machine 1 and the ball lending machine 41 without using the dedicated key 14, and as shown in FIG. If the force is applied directly to the second flange member 23 and tilted downward against the second flange member 23, the same flange member 23 is detached from the second metal fitting 7. However, the operation of the second rod member 23 is not transmitted to the first rod member 21 that has not been unlocked due to the action of the second transmission blocking mechanism C and the second transmission path intermittent portion E. That is, although the second rod member 23 tilts downward, the pressure receiving portion 34 is only separated upward from the pressing portion 33, and the movement of the second rod member 23 is not transmitted to the connecting rod 20. As a result, both the connecting rods 25 and 26 do not move, and the first rod member 21 continues to be locked to the first metal fitting 6. The front frame 3 remains closed.

  As described above, according to the present embodiment, in the locking device 8 in which all the hook members 21 and 23 are detached from the metal fittings 6 and 7 by unlocking the dedicated key 14, the first hook member 21 is a wire rod or the like. Thus, even if it is moved illegally and removed from the first receiving bracket 6, the second flange member 23 does not come off from the second receiving bracket 7. For this reason, unlike the conventional locking device, unauthorized unlocking can be prevented.

  By the way, as another measure to prevent unauthorized unlocking, when the unlocking operation is performed using the dedicated key, all the hook members move, and when the other unlocking operations are performed, the hook member does not move. It is possible to do so. For this purpose, for example, a locking member that locks the movement of the connecting rod when locking is completed is supported by the connecting rod, and an unlocking mechanism that unlocks the locking member only when an unlocking operation is performed using a dedicated key is provided. . In this way, during the unlocking operation using the dedicated key, the lock member is unlocked by the action of the lock release mechanism, the connecting rod is moved, and the hook member is tilted to be detached from the receiving metal fitting. However, at the time of an unauthorized unlocking operation that directly tilts the flange member, the connecting rod locked by the lock member does not move, and all the flange members continue to be locked to the receiving metal fittings. Therefore, the same effects as those of the present embodiment can be obtained with respect to preventing unauthorized unlocking.

  On the other hand, the above measures complicate the structure of the entire locking device including the lock member and the lock mechanism, and increase the number of parts. On the other hand, in this embodiment, the above locking mechanism is not added. In order to cut off the power transmission from the first flange member 21 to the second flange member 23, the connecting rods 25 and 26 are connected to each other by the elongated holes 37 and the engagement pins 38 so as to be extendable and contracted. In order to cut off the power transmission to the first flange member 21, a part of the second connecting rod 26 is used as the pressing portion 33, and the pressure receiving portion 34 is only formed on a part of the second flange member 23. These structures are very simple and have a small number of parts. Therefore, this embodiment is superior to the above measures in terms of assembly workability, maintenance, manufacturing cost, and the like.

  The present embodiment has the following characteristics in addition to the matters described above.

  (A) The key unlocking transmission mechanism A and the first transmission blocking mechanism B can be established with a small and simple configuration of the first coupling rod 25, the second coupling rod 26, and the first transmission path intermittent portion D. . In addition, the first transmission path intermittent portion D can be established with a small and simple configuration of the guide portion, the engaging protrusion, and the first elastic member. Furthermore, the guide portion (the long hole 37) can be provided only by performing a simple process such as punching on the first connecting rod 25 or the second connecting rod 26.

  (B) A second transmission blocking mechanism C is provided that blocks the movement of the coffin member 23 in response to the unlocking operation on the second coffin member 23 from being transmitted to the first coffin member 21 that has not been unlocked. ing. Therefore, the locking device 8 is prevented from being unlocked not only when the first hook member 21 is illegally unlocked but also when the second hook member 23 is illegally unlocked. be able to. Unauthorized unlocking can be prevented more reliably.

  (C) The key unlocking transmission mechanism A and the second transmission blocking mechanism C are configured with a small and simple configuration of the coupling rod 20 (the first coupling rod 25, the second coupling rod 26) and the second transmission path interrupting portion E. Can be established. In addition, the second transmission path intermittent portion E can be established with a small and simple configuration of the pressing portion 33, the pressure receiving portion 34, and the second elastic member.

(D) The upper end edge of the second connecting rod 26 is used as the pressing portion 33. Further, the pressure receiving portion 34 is formed by bending a part of the second flange member 23. For this reason, it is only necessary to perform a simple process such as a bending process in order to form the pressing part 33 and the pressure receiving part 34.
(Second Embodiment)
Next, a second embodiment embodying the present invention will be described with reference to FIGS. The second embodiment is significantly different from the first embodiment in that a hook member unlocking transmission mechanism F is provided instead of the second transmission blocking mechanism C. The heel member unlocking transmission mechanism F is for transmitting the operation of the same heel member 23 according to the unlocking operation on the second heel member 23 to the first heel member 21 which is not unlocked. The first transmission path intermittent portion D described above is included. Specifically, in the first embodiment, the second rod member 23 is connected to the second connecting rod 26 in the same manner as the first rod member 21 is connected to the first connecting rod 25 by the connecting pin 29. The pins 42 are connected. The pressing part 33 and the pressure receiving part 34 are omitted. With the omission of the pressure receiving portion 34, one end (upper end) of the second coil spring 36 is hooked on the upper end portion of the second connecting rod 26. In addition, about the member similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In this embodiment, the movement of each part when the unlocking operation is performed using the dedicated key 14 is substantially the same as in the first embodiment. The difference from the first embodiment is that power transmission from the second connecting rod 26 to the second flange member 23 is performed by the connecting pin 42 instead of the pressing portion 33 and the pressure receiving portion 34. Further, the movement of each part when the unlocking operation is performed on the first brim member 21 with a wire or the like without using the dedicated key 14 is the same as in the first embodiment. As shown in FIG. 6 (a), even if the first hook member 21 is tilted downward by applying a direct force to the first hook member 21 and removed from the first metal fitting 6, the first connecting hook 25 resists the first coil spring 31. However, only the engagement pin 38 moves through the long hole 37, and the second connecting rod 26 does not move. The second flange member 23 continues to be locked to the second metal fitting 7 and the front frame 3 remains closed.

  As shown in FIG. 6B from the upper side of the pachinko gaming machine 1 without using the dedicated key 14, a force is directly applied to the second saddle member 23 against the second coil spring 36. When tilted downward, the cogwheel member 23 is detached from the second metal fitting 7. The tilt of the second rod member 23 is transmitted to the second connecting rod 26 by the connecting pin 42, and the connecting rod 26 is pulled up. At this time, since the rotation transmitting portion 32 is only separated upward from the first protrusion 17 of the cam plate 19, there is no possibility of adversely affecting the cylinder lock 15. The movement of the second connecting rod 26 is transmitted to the first connecting rod 25 by the action of the first transmission path intermittent portion D. Specifically, the movement of the second connecting rod 26 is transmitted to the first connecting rod 25 through the engaging pin 38 positioned at the lower end of the long hole 37. The first connecting rod 25 is integrated with the second connecting rod 26 and moves upward (unlocking direction) against the tensile force of the first coil spring 31. This movement is transmitted to the first flange member 21 through the connecting pin 29, and the flange member 21 is tilted downward and detached from the first metal fitting 6. Thus, the operation of the second hook member 23 is also transmitted to the first hook member 21 that has not been unlocked by the action of the hook member unlocking transmission mechanism F including the first transmission path intermittent portion D, The eaves member 21 comes off from the first receiving bracket 6 and the front frame 3 can be opened.

  In this way, in a general pachinko gaming machine in which the first saddle member is located at the lower part of the front frame and the second saddle member is located at the upper part, an unauthorized unlocking operation is performed on the first saddle member. In addition, this is effective when the unlocking operation is performed on the second saddle member in the inspection of the pachinko gaming machine or the like. The unauthorized unlocking operation is performed only on the specific collar member (first collar member) for the following reason. Since the first saddle member is located in the vicinity of the launching knob 43 and launching lever 44 of the pachinko gaming machine 1 shown in FIG. The heel member can be moved. Unauthorized unlocking operation is inconspicuous and difficult for pachinko hall clerk to find. On the other hand, although it is not impossible to perform an unauthorized unlocking operation on the second hook member, if a wire rod or the like is inserted into the upper part of the gap between the pachinko gaming machine and the ball lending machine, Will take a very different attitude, so cheating is conspicuous and easy to find for shop assistants. In order to unlock the second rod member without conspicuously, the wire rod or the like is inserted from the lower part of the gap, the tip portion is fed upward, and the second rod member is pulled down. Since the location is far away from the second rod member, it is difficult to align the tip of the wire or the like so as to be caught by the second rod member. For this reason, although an unauthorized unlocking operation for the second rod member is possible, it is not easy, and as a result, an unauthorized unlocking operation is performed on the first rod member. In the locking device 8 of the present embodiment, as described above, since the power transmission from the first rod member 21 to the second rod member 23 is interrupted, an unauthorized unlocking operation on the first rod member 21 is performed. However, it is possible to reliably and effectively prevent the second flange member 23 from coming off from the second metal fitting 7 and prevent the front frame 3 from being illegally opened.

  In addition, one of the operations performed when inspecting and assembling pachinko gaming machines in factories and the like is to place the gaming machine on the floor in a standing state and close or open the front frame. At this time, since the workability is poor if the unlocking is performed using the dedicated key one by one, conventionally, the heel member has been pushed down. The object to be pushed down is the second flange member. This is because if the unlocking operation is performed on the second hook member positioned on the upper side, the operator does not have to take an unreasonable posture as compared with the case of performing the unlocking operation on the first hook member positioned on the lower side. It is. In the locking device 8 of the present embodiment, as described above, power transmission is performed from the second rod member 23 to the first rod member 21, so that only the unlocking operation is performed on the second rod member 23. The eaves member 21 can be removed from the first catch 6 and the front frame 3 can be opened. As described above, according to the second embodiment, the second hook member 23 is moved and unlocked easily at the time of inspection or the like while preventing the unauthorized unlocking that moves and unlocks the first hook member 21. Can do. Convenience for work that the conventional locking device has is not impaired.

  Note that the present invention can be embodied in another embodiment described below.

  (1) The locking device of the present invention is a gaming machine that supports the front frame so that the front frame can be opened and closed, and locks the front frame to the outer frame when the front frame is closed. Can be widely applied regardless of the type. Examples of such types include pachislot machines other than the pachinko gaming machines described above.

  (2) Although it has already been described that three or more scissors members may be used in the locking device 8, in this case, scissors other than the first scissors member 21 and the second scissors member 23 (hereinafter referred to as this item). The “other scissors member” in FIG. 5 may be any member that can be disengaged from the metal fitting when the operation of the cylinder lock 15 according to the unlocking operation of the dedicated key 14 is transmitted. The corresponding movement of the cogwheel member 21 may be transmitted or may not be transmitted. In short, it is sufficient that at least one hook member does not move and does not come off the receiving metal fitting when the first hook member 21 is moved illegally. Therefore, it is possible to change within a range that satisfies the above conditions. For example, the other flange member may be connected to the first connecting rod 25 so as to be able to transmit power, or to the second connecting rod 26 so as to be able to transmit power. It may be connected. As a connection structure with respect to the connection rod of the other flange member, a connection pin may be used in the same manner as the connection structure of the first flange member, and the pressing portion and the pressure receiving force are similar to the connection structure of the second flange member. A part may be used.

  (3) The attachment position of the locking device with respect to the front frame is not limited to the location described in the above embodiment (the right side portion of the front frame), and may be, for example, the left side portion, the upper portion, and the lower portion.

  As mentioned above, although embodiment of this invention was described, it describes with technical effect other than the claim which can be grasped | ascertained from each embodiment with those effects.

  In the above locking device, when the unlocking operation is performed on the second hook member with a wire or the like without using a key, the hook member is detached from the locked portion. The movement of the second hook member is transmitted to all the hook members that have not been unlocked by the hook member unlocking transmission mechanism, and these hook members can be detached from the locked portions and the front frame can be opened. It becomes. By the way, one of the work performed when inspecting and assembling the gaming machine in a factory or the like is to place the gaming machine on the floor in a standing state and close or open the front frame. At this time, unlocking with the key one by one results in poor workability, so conventionally the heel member has been directly pushed down. The object to be pushed down is the eaves member located on the upper side. This is because the worker does not have to take an unreasonable posture. In (b), the second eaves member is arranged in such a place where the work is easy (upper part of the front frame). Therefore, it is possible to remove all the hook members from the locked portion by simply moving the second hook member at the time of inspection or the like, while preventing unauthorized unlocking by moving the first hook member. Can be unlocked. In addition, assembly work and inspection work can be performed with an easy posture, and workability can be improved.

  In the above locking device, if an unauthorized unlocking operation is performed on the second hook member, there is a problem that all the hook members that are not unlocked are detached from the locked portion. However, if a wire rod or the like is inserted into the upper part of the gap between the gaming machine and the ball lending machine for an unauthorized unlocking operation on the second saddle member, it will take a significantly different posture from that during normal gaming. , Cheating is noticeable. In order to unlock the second rod member without conspicuously, the wire rod or the like is inserted from the lower part of the gap, the tip portion thereof is fed upward, and the second rod member is pulled down. Is difficult to align so as to be caught by the second flange member. For this reason, although the unauthorized unlocking operation with respect to the 2nd collar member is possible, it is not easy. Such an unlocking operation is not actually performed, and it is considered that there is no risk of the occurrence of the above-mentioned problems.
