Is set relatively long. On the other hand, on the side of the second sliding rod 635, the upper engaging hole 727 located above the lower engaging hole 728 in the up-down direction of the engaging holes 727 and 728 is formed. The formation section is set to be relatively long. This is so that when the cam plate 720 slides one of the first sliding rod 605 or the second sliding rod 635, the upper engaging claw 720a or the lower engaging claw 720b does not come into contact with the other, as described later. This is to prevent the other from sliding.

  With the above configuration, as shown in FIG. 22A, when the lock shaft 703 and the cam plate 720 are in the reference position with the key K not inserted into the key hole 702 of the cylinder lock 700, The tip of the upper engaging claw 720a is inserted into the upper engaging holes 725 and 727 of the first sliding rod 605 and the second sliding rod 635, and the tip of the lower engaging claw 720b makes the first sliding movement. The rod 605 and the second sliding rod 635 are inserted into the lower engaging holes 726 and 728. Further, as described above, the cylinder lock 700 of the present embodiment is in a state (lock state) in which the lock shaft 703 and the cam plate 720 cannot be rotated unless the key K is inserted in the key hole 702. When the cam plate 720 is at the reference position, the engagement claws 720a and 720b restrict the sliding of the first sliding rod 605 and the second sliding rod 635. For example, if a wire rod or the like is illegally hooked on the first sliding rod 605 at the reference position without using the key K, and an external force is applied to the first sliding rod 605 in the unlocking direction. The engaging claws 720a and 720b are caught 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 is caused by the engaging hole 725. It is substantially regulated except play length.

  Next, the operation of the locking device 600 will be described in detail. First, the 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 sliding rod 605 takes the reference position so that the front frame set hooks 17a, 17b, 17c become the front frame set locking parts 610, 611, 612 as described above. The front frame set 14 is engaged and is restricted from opening.

  Then, when unlocking the front frame set 14, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated in the counterclockwise direction when viewed from the front side (see FIG. 1) of the pachinko machine 10. As a result, the cam plate 720 rotates in the same direction, and the upper engaging claw 720a comes into contact with the lower edge of the upper engaging hole 725 of the first sliding rod 605 [see FIG. 22 (b)]. 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 the clockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the upper engagement 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 claws 720b are disengaged from the lower engaging holes 726 and 728 without affecting the first sliding rod 605 and the second sliding rod 635. At this time, since a space for displacing the upper engaging claw 720a downward is secured in the lower portion of the upper engaging hole 727 of the second sliding rod 635 through which the upper engaging claw 720a is inserted, the first sliding In the process of pushing down the moving rod 605, the upper engaging claw 720a does not abut the second sliding rod 635, so that its operation is not hindered.

  When the first sliding rod 605 slides downward, all the front frame set locking parts 610, 611, 612 are disengaged from the front frame set hook parts 17a, 17b, 17c, and the front frame set 14 of the front frame set 14 is released. Opening is allowed. When the front frame set 14 is opened and the force of the hand operating the key K is relaxed, the tension of the coil spring C1 pulls the first sliding rod 605 upward and returns it 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, the second sliding rod 635 takes the reference position, so that the inner frame hooks 637 and 638 are locked to the hook receiving portions 84 and 85 of the outer frame 11, and the inner frame 12 is locked. 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 in the clockwise direction when viewed from the front side of the pachinko machine 10. As a result, the cam plate 720 rotates in the same direction, and the lower engaging claw 720b contacts the upper edge portion of the lower engaging hole 728 of the second sliding rod 635 [see FIG. 22 (c)]. 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 claws 720a are disengaged from the upper engaging holes 725 and 727 without affecting the first sliding rod 605 and the second sliding rod 635. At this time, since a space for displacing the lower engaging claw 720b upward is secured in the upper part of the lower engaging hole 726 of the first sliding rod 605, through which the lower engaging claw 720b is inserted, the second sliding bar 720b is secured. In the process of pushing up the moving rod 635, the lower engaging claw 720b does not abut 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 hook portions 637 and 638 and the hook receiving portions 84 and 85 is released, and the inner frame 12 is allowed to open. Further, when the force of the hand that operates the key K is relaxed when the inner frame 12 is opened, the second sliding rod 635 is pulled down 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 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, as in the case of the front frame set 14, the first sliding rod 605 takes the reference position, so that the board unit hook portion 620 causes the second control board unit 202 to receive the metal fitting. 205, the opening of the second control board unit 202 is restricted.

  Similarly, when the back pack unit 203 is locked, the first sliding rod 605 takes the reference position, so that the back pack hooks 621 and 622 are engaged with the receiving fittings 204 of the back pack unit 203, and the back pack unit 203 is locked. The opening of the unit 203 is restricted.

  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 the same as in the case of the front frame set 14. Is rotated counterclockwise as viewed from the front side of the pachinko machine 10. 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. After that, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes down the first sliding rod 605 downward against the tensile force of the coil spring C1, and the board unit hook portion 620 is formed. The engagement with the receiving bracket 205 is released, the opening of the second control board unit 202 is allowed, and the engagement between the back pack hooks 621 and 622 and the receiving bracket 204 is released, and the back pack unit 203 is released. Is acceptable.

  As described above, in the present embodiment, when the key K is not inserted in 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, so that When locking the inner frame 12, the front frame set 14, the second control board unit 202 or the back pack unit 203 in the opened state, the key K cannot be used for locking. Therefore, for example, when the inner frame 12 in the open state is closed without using the key K, the inclined portions of the head portions 637c, 638c of the inner frame hook portions 637, 638 are the hook holes of the hook receiving portions 84, 85. Even if the second sliding rod 635 is hit by the lower edges of the portions 84a and 85a and an external force is applied to the second sliding rod 635 in the upward direction, 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 key K is used to operate the cylinder lock 700 so that the inner frame hooks 637 and 638 are unlocked. With the second sliding rod 635 slidably displaced to the lock position, the inner frame 12 is closed, and the heads 637c and 638c move the lower edge portions of the hook hole portions 84a and 85a of the hook receiving portions 84 and 85. A method is adopted in which the second sliding rod 635 is returned to the locking position after the inner frame 12 is completely closed and the inner frame 12 is completely closed. In addition, a method of closing the inner frame 12 without operating the key K with the key K inserted in 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, 638c of the inner frame hook portions 637, 638 collide with the lower edge portions of the hook hole portions 84a, 85a of the hook receiving portions 84, 85, An external force is applied to the second sliding rod 635 in the upward direction, 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 hook portions 637 and 638 pass over the lower edge portions of the hook hole portions 84a and 85a of the hook receiving portions 84 and 85, the second sliding rod 635 pulls the tensile force of the coil spring C1. To return to the original position. As a result, the inner frame hook portions 637 and 638 are locked to the hook 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 the present 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. Since it is integrated with the above, it is possible to suppress an increase in the number of parts and improve convenience such as workability at the time of maintenance.

  In addition, the hooks such as the inner frame hooks 637 and 638 are integrally formed with the first sliding rod 605 and the second sliding rod 635, and the key K is not inserted into the key hole 702 of the cylinder lock 700. In, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. Therefore, for example, even when the first sliding rod 605 or the second sliding rod 635 is directly unlocked by the wire rod or the like without using the key K, that is, an unauthorized unlocking operation is performed, Since the sliding rod 605 or the second sliding rod 635 is maintained in the locked position, opening of the inner frame 12 or the like is not allowed. As a result, the defense performance against unauthorized unlocking using a wire rod or the like can be improved.

  Further, the back pack unit 203 is arranged on the back side of the inner frame 12 so as to cover the control devices such as the main control device 261 and the back pack unit 203 is locked to the inner frame 12. .. Therefore, even if the inner frame 12 is illegally opened, it becomes difficult for the back pack unit 203 to perform an illegal act on a control device such as the main controller 261. As a result, it is possible to further enhance the defense performance against unauthorized unlocking using a wire rod or the like.

  In addition, in the present embodiment, the locking device 600 is attached to the front surface side of the inner frame 12, and only the respective hook portions such as the inner frame hook portions 637 and 638 engaged with the outer frame 11 and the like are the inner frame. 12 is exposed on the back side. Therefore, the exposed portion on the back side of the inner frame 12 can be reduced as much as possible, and a wire rod such as a wire is temporarily inserted through the gap between the inner frame 12 and the outer frame 11 to illegally unlock the inner frame 12. Even if an attempt is made, there are few parts where the wire rod can be hooked, and it becomes more difficult to carry out the cheating. As a result, it is possible to further enhance the defense performance against unauthorized unlocking using a wire rod or the like.

  Further, when 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 surfaces of the mounting groove portion 901. Therefore, various members such as the first sliding rod 605 arranged on the back surface side of the base frame 601 are in a state of being surrounded by the mounting groove portion 901 and the base frame 601. Therefore, even if a wire or the like is inserted through the gap between the front frame set 14 and the inner frame 12, the wire or the like is made to enter the back side of the base frame 601 on which the first sliding rod 605 or the like is arranged. It is difficult to operate the first sliding rod 605 and the like. As a result, it is possible to further improve the defense performance.

  Further, in the present embodiment, since the locking device 600 is fixed from the front side of the inner frame 12 with the screw 904, it is not hindered by various control devices and wirings provided on the back side of the inner frame 12. It becomes possible to relatively easily perform the mounting work and the replacement work. As a result, it is possible to improve convenience such as workability.

  Further, in the present embodiment, the extended frame 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 in the outer frame 11. As a result, it becomes more difficult to allow a wire rod or the like to enter from the back side of the outer frame 11 and operate the hook portions such as the inner frame hook portions 637 and 638 with the wire rod or the like. As a result, it is possible to further improve the defense performance.

  Further, when the inner frame hook portions 637 and 638 are engaged with the hook receiving portions 84 and 85, the peripheral wall portions of the hook receiving portions 84 and 85 surround the inner frame hook portions 637 and 638. This makes it difficult to disengage the inner frame hook portions 637 and 638 from the hook receiving portions 84 and 85 by the wire material or the like. As a result, it is possible to further improve the defense performance.

  It should be noted that the present invention is not limited to the contents described in the above embodiment, and may be implemented as follows, for example.

  (A) In the above 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 embodied by a single locking device 600. Has been done. However, the configuration of the locking device 600 is not limited to the above embodiment. For example, in a configuration in which the second control board unit 202 and the back pack unit 203 are not locked to the inner frame 12, the locking mechanism of the units 202 and 203 is omitted, and the locking mechanism of the inner frame 12 and the front frame set 14 are locked. You may employ the locking device which consists only of a mechanism. Alternatively, only one of the second control board unit 202 and the back pack unit 203 may be locked to the inner frame 12, and a locking device suitable for this may be adopted. Further, in addition to the second control board unit 202 and the back pack unit 203, the first control board unit 201 is locked to the inner frame 12, and three or more door bodies are locked on the back side of the inner frame 12. It is also possible to adopt a locking device adapted to this.

  (B) In the above-described embodiment, regarding the locking mechanism of the front frame set 14, front frame set hooks 17a, 17b, 17c having claws are provided on the front frame set 14 side, and the claws are provided on the locking device 600 side. The front frame set locking portions 610, 611, 612 that engage with the locking portion are provided, but a hook member having a claw portion is provided on the locking device 600 side and the front frame set locking portion 610, 611, 612 engages with the claw portion. You may provide a part. In this case, when unlocking, the hook member on the locking device 600 side operates. Of course, the same applies to the locking mechanism of the second control board unit 202 and the back pack unit 203.

  (C) The sliding directions of the first sliding rod 605 and the second sliding rod 635 may be opposite. That is, in the above-described embodiment, for example, when the second sliding rod 635 slides upward, the inner frame hook portions 637 and 638 are separated from the hook receiving portions 84 and 85. A configuration may be adopted in which the inner frame hook portions 637 and 638 are disengaged from the hook receiving portions 84 and 85 as the moving rod 635 slides downward.

  (D) In the above-described embodiment, the inner frame 12 is unlocked by inserting the key K into the key hole 702 of the cylinder lock 700 and rotating clockwise, and the front is opened by rotating counterclockwise. The frame set 14, the second control board unit 202, and the back pack unit 203 are unlocked. The unlocking operation is not limited to this, and may be another unlocking operation as long as the unlocking operation of at least the inner frame 12 and the front frame set 14 is different. For example, the unlocking operation may be different. As an example, a cylinder lock different from the cylinder lock 700 is adopted, and the third and fourth sliding rods are provided, so that the inner frame 12 is unlocked by a clockwise rotation operation. The front frame set 14 is unlocked by rotating clockwise, and the second control board unit 202 is unlocked by rotating clockwise when the lock shaft is slid inward, A configuration in which the back pack unit 203 is unlocked by rotating the lock shaft in the counterclockwise direction while sliding the lock shaft to the back side can be mentioned.

  (E) At least when the inner frame 12 is locked to the outer frame 11, the locked states of the second control board unit 202 and the back pack unit 203 locked to the inner frame 12 cannot be unlocked. When 12 is open, the locked state of both units 202 and 203 may be unlocked. With this configuration, it is possible to further improve the defense performance against unauthorized unlocking using a wire rod or the like.

  (F) The configuration of each hook portion such as the inner frame hook portions 637 and 638 is not limited to the above embodiment. For example, in the above embodiment, the hooks such as the inner frame hooks 637 and 638 are integrally formed with the first sliding rod 605 and the second sliding rod 635, but the present invention is not limited to this, and the inner frame hooks are not limited thereto. The hook members constituting 637, 638 and the like may be fixed to the first sliding rod 605 and the second sliding rod 635 by a fixing means such as screws so that they cannot be displaced relative to each other, or the inner frame hook portion 637, A hook member that configures 638 or the like may be provided so as to be capable of relative displacement with respect to the first sliding rod 605 and the second sliding rod 635.

  Further, in the above embodiment, the hook portion having a substantially triangular head portion that is tapered toward the tip is adopted, but the present invention is not limited to this, and for example, the tip portion of the head is substantially linear along the vertical direction. You may employ the hook part formed. In the above embodiment, the cam plate 720 restricts the sliding displacement of the first sliding rod 605 and the second sliding rod 635 when the key K is not inserted into the cylinder lock 700. If the inner frame 12 or the like in the open state is forcibly closed without using the key K, a force in the unlocking direction is applied to the first sliding rod 605 and the second sliding rod 635, and the cam plate 720. May be damaged. On the other hand, if the above configuration is adopted, when the inner frame 12 or the like in the open state is closed without using the key K, the tip ends of the heads of the hooks of the inner frame hooks 637 and 638 receive the hook. Even when the engaged portions such as the portions 84 and 85 are brought into contact with each other, the above-mentioned inconvenience does not occur because no force is applied to the first sliding rod 605 and the second sliding rod 635 in the unlocking direction.

  Further, the number of hooks such as the inner frame hooks 637 and 638 and the respective engaged portions such as the hook receiving portions 84 and 85 corresponding thereto is not limited to the number in the above-described embodiment, and for example, It may be one.

  (G) In the above embodiment, the mounting groove portion 901 as a device mounting portion for mounting the locking device 600 is formed along the right side portion on the front surface side of the inner frame 12, but the structure of the device mounting portion is It is not limited to the mounting groove portion 901. For example, a device mounting portion formed in a convex shape along the right side portion of the inner frame 12 may be adopted.

  (H) In the above-described embodiment, the base frame 601 that constitutes the outer shell of the locking device 600 is attached to the inner plate 12 and the mounting plate 602, and the rear end from the inner edge of the inner plate 12 of the mounting plate 602. It comprises a projecting support plate 603 and a flange portion 604 projecting rearward from the end of the mounting plate 602 on the outer side of the inner frame 12, and has a substantially U-shaped cross section. However, the shape of the base frame 601 is not limited to this. For example, the flange portion 604 may be omitted, and the cross section may have a substantially L shape.

  (I) In the above-described embodiment, the locking device 600 is fixed from the front side of the inner frame 12 with the screw 904. Not limited to this, for example, a locking claw or the like may be formed on the base frame 601 of the locking device 600, and the locking device 600 may be fixed to the mounting groove portion 901 by the locking claw or the like. Alternatively, the locking device 600 may be fixed from the back side of the inner frame 12 with the screw 904 while being fitted in the mounting groove 901 from the front side of the inner frame 12.

  (J) In the above embodiment, the outer frame 11 is formed with the extending 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. Not limited to this, the extending wall portion 83 may be omitted, or the extending wall portion 83 may be formed only in the portions corresponding to the hook portions such as the inner frame hook portions 637 and 638.

  (K) In the above embodiment, the peripheral wall portions of the hook receiving portions 84 and 85 surround the inner frame hook portions 637 and 638 in a state where the inner frame hook portions 637 and 638 are engaged with the hook receiving portions 84 and 85. It becomes a state. Not limited to this, an engaged portion (receptacle) with which the inner frame hook portions 637 and 638 are engaged, and a cover member that surrounds the inner frame hook portions 637 and 638 engaged with the engaged portion. It may be configured as a separate body.

  (L) A cylinder lock different from the cylinder lock 700 may be adopted. For example, the cylinder lock 700 of the above embodiment is in the locked state when the key K is not inserted, and the cam plate 720 cannot be displaced. When the first sliding rod 605 and the second sliding rod 635 are in the reference position, the tip of the upper engaging claw 720a causes the upper engagement of the first sliding rod 605 and the second sliding rod 635. While being inserted into the holes 725 and 727, the tip of the lower engaging claw 720b is inserted into the lower engaging holes 726 and 728 of the first sliding rod 605 and the second sliding rod 635. As a result, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. The invention is not limited to this, and a cylinder lock in which the cam plate 720 cannot be displaced may be adopted. Further, when the first sliding rod 605 and the second sliding rod 635 are at the reference position, the engaging claws 720a and 720b are not inserted into the engaging holes 725 and the like, and the first sliding rod 605 and the first sliding rod 605 are not inserted. A configuration in which the sliding of the two-sliding rod 635 is not restricted may be adopted.

  Alternatively, a cylinder lock whose key code can be changed may be adopted. As an example of the procedure for changing the key code, first, the current key is inserted into the key hole with a predetermined reset pin being pressed, the key is rotated, and then the key is pulled out. Then, while pressing the reset pin, a key to be newly set is inserted into the key hole, and the key is pulled out after releasing the pressed state of the reset pin after rotating the key in the opposite direction to the current key. By performing the above operation, it is possible to obtain a key code suitable for a key to be newly set. As a result, the keys can be unified for each game hall, and the keys can be changed regularly to prevent fraud.
