Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Generally, in gaming machines such as pachinko machines, a gaming machine main body (inner frame) is provided to be openable and closable with respect to a fixed frame (outer frame) from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the store clerk cannot open the gaming machine body without permission.

  As such a locking device, a main body locking mechanism that locks the gaming machine main body with respect to the fixed frame, and a front door locking mechanism that locks the gaming machine main body with a front door that can be opened and closed on the front side of the gaming machine main body. What you have is known. For example, a cylinder lock that is operated using a dedicated key, a main body hook member that is detachably attached to the engaged portion on the fixed frame side, and an engaged portion on the front door side. A front door saddle member detachably provided, a first transmission mechanism for transmitting the operation of the cylinder lock to the main body saddle member in response to a rotation operation in one direction by the key, and a key in the other direction There is one provided with a second transmission mechanism that transmits the operation of the cylinder lock according to the turning operation to the front door rod member. In the locked state of the gaming machine main body and the front door, each hook member is engaged with the corresponding engaged portion, so that the gaming machine main body cannot be opened with respect to the fixed frame, and the front door is attached to the gaming machine main body. On the other hand, it becomes impossible to open. In addition, by rotating the cylinder lock in one direction with a dedicated key, the main body saddle member is detached from the engaged portion, and the gaming machine main body can be opened. On the other hand, by rotating the cylinder lock in the other direction, the front door hook member is detached from the engaged portion, and the front door can be opened.

  In recent years, gaming halls have been used for illegal activities to acquire a large number of gaming media by illegally unlocking the gaming machine body during operation and illegally operating or exchanging control devices provided on the back side of the gaming machine. Sometimes it is. Such unauthorized unlocking is usually performed by inserting a wire such as a wire from the gap between the gaming machine main body and the fixed frame, and hooking the wire on the main body hook member of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on the main body hook member, the main body hook member is detached from the engaged portion, and the gaming machine main body can be opened.

  In addition, as means for preventing an illegal act on a control device or the like, there is a locking device that locks a mechanism plate or the like provided on the back side of the gaming machine main body to the gaming machine main body (see, for example, Patent Document 1). In this way, if the mechanism plate or the like is locked to the gaming machine main body, it is difficult for an illegal act to the control device or the like to be performed.

JP-A-11-28284

  However, as in the invention described in Japanese Patent Application Laid-Open No. 11-28284, in the configuration in which the locking device for the mechanism plate is provided separately from the locking device for the gaming machine main body, there is a concern about an increase in the number of parts. Furthermore, since the positions of these locking devices, that is, the positions of the lock members into which the keys are inserted, are scattered at a plurality of locations, the operation of opening the mechanism plate during maintenance or the like may become troublesome.

  For this reason, in consideration of convenience, it is conceivable that the locking mechanism of the mechanism plate is integrated with the locking device including the locking mechanism of the gaming machine body and the locking mechanism of the front door. For example, when the cylinder lock is rotated in a predetermined direction with a dedicated key by combining the transmission mechanism that constitutes the locking mechanism of the front door, the front door hook member and the mechanism plate hook member are It can be set as the structure which can detach | leave from a to-be-engaged part, and can each open | release a front door and a mechanism board.

  However, in such a configuration, when one of the front door rod member and the mechanism plate rod member is detached from the engaged portion, the other flange member is also detached from the engaged portion at the same time. Therefore, when closing the front door in the open state, for example, after the maintenance on the front side of the gaming machine main body is finished, once the front door saddle member is displaced to the release side, the front door saddle member The mechanism plate saddle member is also displaced toward the separation side. Therefore, in some cases, such as when the momentum to close the front door is strong, the mechanism plate may be opened on the back side of the main body, or the mechanism plate position may shift and the mechanism plate saddle member may not return to the engaged position normally. There is a possibility that the engaged portion cannot be engaged. If the mechanism plate heel member does not return to the engaged position, the front door ridge member interlocked by the same transmission mechanism is also not engaged with the engaged portion, so that neither the front door nor the mechanism plate can be locked. . In such a state, as in the case of performing maintenance on the back side of the gaming machine main body, the gaming machine main body is once unlocked and opened, the mechanism plate is closed, and then the gaming machine main body is closed. It takes time-consuming work. In addition, when performing the operation of closing the mechanism plate in the open state, the same problem as described above that the front door is opened may occur. Thus, in the locking device having the above-described configuration, care must be taken when performing the locking and unlocking operations of the front door and the mechanism plate.

In addition, the subject illustrated above is a problem applicable not only to a pachinko machine but also to other gaming machines having a similar structure.

  The first sliding rod 605 and the second sliding rod 635 are urged upward or downward by a coil spring C1 as urging means. More specifically, an extension part 650 extending rearward is formed at a position slightly below the upper back pack collar part 621 at the rear end edge of the main body part 636 of the second sliding collar 635. . On the other hand, the rear end edge of the supporting side wall portion 607 of the first sliding rod 605 faces rearward at a height position between the upper front frame set locking portion 610 and the middle front frame set locking portion 611. An extending portion 651 that extends is formed. Note that the extending portion 651 of the first sliding rod 605 is set to have a relatively long vertical section compared to the extending portion 650 of the second sliding rod 635. For this reason, the extending portion 650 of the second sliding rod 635 overlaps the extending portion 651 at the approximately vertical center of the extending portion 651 of the first sliding rod 605. Then, one end of the coil spring C1 is hooked on the hook portion 653 provided in the extending portion 650 of the second sliding rod 635, and the other end is provided at the lower end portion of the extending portion 651 of the first sliding rod 605.

  The cylinder body 701 is formed with a total of 16 through-holes 706, each of which is vertically connected to the inside and outside of the cylinder body 701. Correspondingly, 16 through holes 708 communicating with the respective through holes 706 are also formed in the lock shaft 703. The key hole 702 side of the through hole 708 is formed with a smaller diameter than other parts so that a receiving member such as a pin 714 described later does not fall into the key hole 702.

  A spring 709 is accommodated in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and a pedestal 711 is connected to the other end. Each through hole 708 accommodates a plurality of spacers 712, 713 and pins 714 so as to be supported by the pedestal 711. The pins 714, the spacers 712 and 713, and the pedestal 711 can move up and down in the through holes 706 and 708 by the expansion and contraction of the spring 709. Among these, the pin 714 can be projected and retracted in the key hole 702 through a small diameter portion of the through hole 708 on the key hole 702 side.

  With the above configuration, when the key K is inserted into the keyhole 702, the pins 714 and the like move up and down along the concave and convex shapes on both the upper and lower sides of the key K. When the key K is completely inserted, each pin 714 enters the key K groove as shown in FIG. 21, and the base end surface of the pin 714 or one end surface of the spacer 712 or 713 And the outer peripheral surface of the lock shaft 703 are flush with each other. As a result, when the key K is completely inserted, the lock shaft 703 can be rotated as the key K is rotated. That is, the cylinder lock 700 has an internal structure in which the lock shaft 703 cannot be rotated unless at least the key K is inserted into the key hole 702.

  In addition, a cam plate 720 as an engagement member that transmits the rotational movement of the key K inserted into the key hole 702 to the first sliding rod 605 or the second sliding rod 635 is provided at the rear end of the lock shaft 703. It is fixed.

  The cam plate 720 includes a pair of upper and lower upper engaging claws 720a and lower engaging claws 720b as shown in FIG. These engaging claws 720a and 720b are formed at a predetermined interval in the rotational direction of the cam plate 720 and are shifted in the front-rear direction. More specifically, the upper engagement claw 720a is located behind the lower engagement claw 720b (see FIG. 16 and the like).

  Accordingly, a pair of upper and lower upper engagement holes 725 and 726 in which the engaging claws 720a and 720b can enter and exit are formed in the bulging portion 607a of the first sliding rod 605. Similarly, a pair of upper and lower upper engagement holes 727 and 728 through which the engagement claws 720a and 720b can enter and exit are formed in the bulging portion 636a of the second sliding rod 635. Further, a through hole 730 is formed in the support plate 603 so as not to hinder the operation of the engaging claws 720a and 720b.

  The engagement holes 725 and 726 of the first sliding rod 605 and the engaging holes 727 and 728 of the second sliding rod 635 are in a superimposed state of the first sliding rod 605 and the second sliding rod 635. At least the upper engagement holes 725 and 727 and the lower engagement holes 726 and 728 are in communication with each other (see FIG. 22).

  Note that, on the first sliding rod 605 side, a lower engagement hole 726 formation section positioned below the upper engagement hole 725 positioned above the engagement holes 725 and 726 in the vertical direction. Is set relatively long. On the other hand, on the second sliding rod 635 side, the upper engagement hole 727 located above the vertical engagement section of the lower engagement hole 728 located below the both engagement holes 727 and 728. The formation section is set to be relatively long. As described later, when the cam plate 720 slides one of the first sliding rod 605 or the second sliding rod 635, the upper engagement claw 720a or the lower engagement claw 720b is not brought into contact with the other. In order to prevent the other from sliding.

  22A, when the lock shaft 703 and the cam plate 720 are at the reference position in a state where the key K is not inserted into the key hole 702 of the cylinder lock 700, as shown in FIG. The tip of the upper engagement claw 720a is inserted into the upper engagement holes 725 and 727 of the first sliding rod 605 and the second sliding rod 635, and the tip of the lower engagement claw 720b is the first sliding rod. The hook 605 and the second sliding rod 635 are inserted into the lower engagement holes 726 and 728. In addition, as described above, the cylinder lock 700 according to the present embodiment is in a state (locked state) in which the lock shaft 703 and the cam plate 720 cannot be rotated when the key K is not inserted into the key hole 702. When the cam plate 720 is at the reference position, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted by the engaging claws 720a and 720b. For example, when an external force in the unlocking direction is applied to the first sliding rod 605 by improperly hooking a wire or the like on the first sliding rod 605 at the reference position without using the key K The engaging claws 720a and 720b are hooked on the edges of the engaging holes 725 and 726 of the first sliding rod 605, and the sliding displacement of the first sliding rod 605 in the unlocking direction causes the engaging hole 725 to move. It is practically regulated except for the play length.

  Next, the operation of the locking device 600 will be described in detail. First, locking and unlocking of the front frame set 14 will be described in detail. In the locked state of the front frame set 14, the first slide bar 605 takes the reference position, so that the front frame set bar parts 17 a, 17 b, and 17 c are connected to the front frame set lock parts 610, 611, 612 as described above. The front frame set 14 is restricted from being engaged.

  When the front frame set 14 is unlocked, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise as viewed from the front side of the pachinko machine 10 (see FIG. 1). As a result, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a contacts the lower edge portion of the upper engagement hole 725 of the first sliding rod 605 (see FIG. 22B). However, since FIG. 22B is a view seen from the back side of the pachinko machine 10, the rotation direction of the cam plate 720 is a clockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes the first sliding rod 605 downward against the tensile force of the coil spring C1. At the same time, the lower engaging claw 720b is detached from both the lower engaging holes 726 and 728 without acting on the first sliding rod 605 and the second sliding rod 635. At this time, a space for the upper engagement claw 720a to be displaced downward is secured below the upper engagement hole 727 of the second sliding rod 635 through which the upper engagement claw 720a is inserted. In the process of pushing down the moving rod 605, the upper engaging claw 720a does not come into contact with the second sliding rod 635 so that the operation is not hindered.

  When the first sliding rod 605 slides downward, the engagement of all the front frame set locking portions 610, 611, 612 and the front frame set collars 17a, 17b, 17c is released, and the front frame set 14 Opening is allowed. When the front frame set 14 is opened, if the force of the hand operating the key K is loosened, the first sliding rod 605 is pulled upward by the tensile force of the coil spring C1, and returns to the reference position. . Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  Next, locking and unlocking of the inner frame 12 will be described in detail. In the locked state of the inner frame 12, when the second sliding rod 635 takes the reference position, the inner frame flange portions 637 and 638 are locked to the flange receiving portions 84 and 85 of the outer frame 11. Opening is regulated.

  Then, when unlocking the inner frame 12, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise as viewed from the front side of the pachinko machine 10. Thereby, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b contacts the upper edge portion of the lower engagement hole 728 of the second sliding rod 635 (see FIG. 22C). However, since FIG. 22C is a view seen from the back side of the pachinko machine 10, the rotation direction of the cam plate 720 is the counterclockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the lower engagement claw 720b pushes the second sliding rod 635 upward against the tensile force of the coil spring C1. At the same time, the upper engaging claw 720a is detached from the upper engaging holes 725 and 727 without acting on the first sliding rod 605 and the second sliding rod 635. At this time, a space for the lower engagement claw 720b to be displaced upward is secured above the lower engagement hole 726 of the first sliding rod 605 through which the lower engagement claw 720b is inserted. In the process of pushing up the moving rod 635, the lower engaging claw 720b does not come into contact with the first sliding rod 605 so that its operation is not hindered.

  When the second sliding rod 635 slides upward, the engagement between the inner frame collar portions 637 and 638 and the collar receiving portions 84 and 85 is released, and the opening of the inner frame 12 is allowed. Further, when the force of the hand operating the key K is loosened when the inner frame 12 is opened, the second sliding rod 635 is pulled downward by the tensile force of the coil spring C1, and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  Next, the locking and unlocking of the second control board unit 202 and the back pack unit 203 will be described in detail.

  In the locked state of the second control board unit 202, the second sliding bar 635 takes the reference position as in the case of the inner frame 12, so that the board unit bar 620 can receive the metal fitting 205 of the second control board unit 202. And the opening of the second control board unit 202 is restricted.

  Similarly, in the locked state of the back pack unit 203, when the second sliding bar 635 takes the reference position, the back pack bar parts 621 and 622 are engaged with the receiving bracket 204 of the back pack unit 203, and the back pack unit 203 is engaged. The opening of the unit 203 is restricted.

  Then, when unlocking the second control board unit 202 and the back pack unit 203, after opening the inner frame 12, the key K inserted into the key hole 702 of the cylinder lock 700 is released as in the case of the inner frame 12. The pachinko machine 10 is rotated clockwise as viewed from the front side. As a result, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b contacts the upper edge portion of the lower engagement hole 728 of the second sliding rod 635. Thereafter, as the cam plate 720 is further rotated, when the lower engagement claw 720b pushes up the second sliding rod 635 upward against the tensile force of the coil spring C1, the substrate unit collar 620 and The engagement with the receiving metal fitting 205 is released, the opening of the second control board unit 202 is allowed, and the engagement between the back pack collar parts 621 and 622 and the receiving metal fitting 204 is released, and the back packing unit 203 is opened. Is acceptable.

  As described above, in the present embodiment, when the key K is not inserted into the key hole 702 of the cylinder lock 700, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. When the inner frame 12, the front frame set 14, the second control board unit 202, or the back pack unit 203 in the open state is locked, the lock cannot be performed unless the key K is used. For this reason, for example, when the inner frame 12 in the open state is closed without using the key K, the inclined portions of the heads 637c and 638c of the inner frame collar portions 637 and 638 are the holes of the collar receiving portions 84 and 85. Even if the second sliding rod 635 collides with the lower edge of the portions 84a and 85a and an external force is applied to the second sliding rod 635, the second sliding rod 635 does not slide upward, and the inner frame 12 is closed. It is not possible. Therefore, when locking the inner frame 12 in the open state, the cylinder lock 700 is operated using the key K, and the position where it is not obstructed by the hook receiving portions 84 and 85, that is, the inner frame hook portions 637 and 638 are unlocked. With the second sliding rod 635 slidably displaced to the locked position, the inner frame 12 is closed, and the heads 637c and 638c are attached to the lower edge portions of the hole portions 84a and 85a of the hook receiving portions 84 and 85. After the inner frame 12 is completely closed, the second sliding rod 635 is returned to the locking position. In addition, a method of closing the inner frame 12 without operating the key K while the key K is inserted into the key hole 702 of the cylinder lock 700 is also possible. In this case, when the inner frame 12 is closed and the inclined portions of the head portions 637c and 638c of the inner frame flange portions 637 and 638 collide with the lower edge portions of the hole portions 84a and 85a of the flange receiving portions 84 and 85, An external force in the upward direction is applied to the second sliding rod 635, and the second sliding rod 635 slides upward against the tensile force of the coil spring C1. When the head portions 637c and 638c of the inner frame flange portions 637 and 638 get over the lower edge portions of the hole portions 84a and 85a of the flange receiving portions 84 and 85, the second sliding rod 635 is pulled by the tensile force of the coil spring C1. To return to the original position. As a result, the inner frame collar portions 637 and 638 are locked to the collar receiving portions 84 and 85. Of course, the front frame set 14, the second control board unit 202, and the back pack unit 203 can be locked by the same locking method.

  As described above in detail, in this embodiment, the locking mechanism of the inner frame 12, the locking mechanism of the front frame set 14, the locking mechanism of the second control board unit 202, and the locking mechanism of the back pack unit 203 are combined into one locking device 600. Therefore, it is possible to suppress the increase in the number of parts and improve convenience such as improvement in workability during maintenance.

  In addition, the flange portions such as the inner frame flange portions 637 and 638 are integrally formed with the first slide rod 605 and the second slide rod 635, and the key K is not inserted into the key hole 702 of the cylinder lock 700. Then, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. For this reason, for example, even when a direct unlocking operation, that is, an unauthorized unlocking operation is performed on the first sliding rod 605 or the second sliding rod 635 with a wire or the like without using the key K, the first Since the sliding rod 605 or the second sliding rod 635 is maintained in the locked position, the inner frame 12 and the like are not allowed to be opened. As a result, the defense performance against unauthorized unlocking using a wire or the like is improved.

  Further, the back pack unit 203 is disposed on the back side of the inner frame 12 so as to cover the control device such as the main controller 261 and the back pack unit 203 is locked to the inner frame 12. . For this reason, it is difficult for the back pack unit 203 to perform an illegal act on a control device such as the main controller 261.

  In the present embodiment, various control devices, various mechanisms, and the like are divided into three units such as the first control board unit 201, the second control board unit 202, and the back pack unit 203. It is possible to improve the workability in the process.

  Furthermore, by moving the second sliding rod 635, that is, by the same operation with the key K, all of the inner frame 12, the second control board unit 202, and the back pack unit 203 can be unlocked simultaneously. As a result, the configuration of the locking device 600 can be simplified, the operation procedure is not complicated, and the convenience can be further improved.

  In addition, when performing one locking operation or unlocking operation of the front frame set 14 or the second control board unit 202 or the like, there is no problem as described in the above problem such that the other is opened. As a result, no special attention is required when performing the locking and unlocking operations of the front frame set 14 and the second control board unit 202 and the convenience is improved.

  In addition, in this embodiment, the locking device 600 is attached to the front side of the inner frame 12, and only the flanges such as the inner frame flanges 637 and 638 engaged with the outer frame 11 and the like are included in the inner frame. 12 is exposed on the back side. For this reason, the portion exposed to the back side of the inner frame 12 can be reduced as much as possible, and a wiret such as a wire is inserted through the gap between the inner frame 12 and the outer frame 11 to perform an illegal act of illegally unlocking the inner frame 12. Even when trying to do so, there are few parts where the wire can be hooked, and it is more difficult to perform the cheating. As a result, the defense performance against unauthorized unlocking using a wire or the like can be further enhanced.

  Further, in a state where the locking device 600 is fitted in the mounting groove portion 901, the support plate 603 and the flange portion 604 are substantially in contact with the side wall surface of the mounting groove portion 901. Accordingly, various members such as the first sliding rod 605 disposed on the back side of the base frame 601 are surrounded by the mounting groove 901 and the base frame 601. For this reason, even if a wire or the like is inserted from the gap between the front frame set 14 and the inner frame 12, the wire or the like is caused to enter the back side of the base frame 601 on which the first sliding rod 605 or the like is disposed. It becomes difficult to operate the first sliding rod 605 and the like. As a result, the defense performance can be further improved.

  Moreover, in this embodiment, since it has the structure which fixes the locking apparatus 600 from the front side of the inner frame 12 with the screw 904, it is not obstructed by various control apparatuses, wiring, etc. which are provided on the rear side of the inner frame 12. Thus, it is possible to perform attachment work, replacement work and the like relatively easily. As a result, it is possible to improve convenience such as improvement of workability.

  In the present embodiment, an extended wall portion 83 that covers the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12 is formed on the outer frame 11. Accordingly, it becomes more difficult to allow a wire rod or the like to enter from the back side of the outer frame 11 and to operate each flange portion such as the inner frame flange portions 637 and 638 by the wire rod or the like. As a result, the defense performance can be further improved.

  Further, when the inner frame collar portions 637 and 638 are engaged with the collar receiving portions 84 and 85, the peripheral wall portion of the collar receiving portions 84 and 85 surrounds the inner frame collar portions 637 and 638. This makes it difficult to disengage the inner frame collars 637 and 638 from the collar receiving parts 84 and 85 with a wire or the like. As a result, the defense performance can be further improved.
