  Generally, in a gaming machine such as a pachinko machine, a gaming machine 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 game machine is provided with a locking device so that a person other than the clerk cannot open the game machine body without permission. Such a locking device includes a cylinder lock operated by using a dedicated key, a plurality of hook members provided to be able to be engaged with and disengaged from a plurality of locked portions provided on a fixed frame, and a cylinder using a key. There is known a device provided with a transmission mechanism for interlocking a plurality of hook members according to an unlocking operation of a lock. In the locked state, each hook member engages with the corresponding locked portion, so that the game machine main body cannot be opened to the fixed frame. On the other hand, when the cylinder lock is unlocked with a dedicated key, each hook member is simultaneously detached from the locked portion via the transmission mechanism, and the game machine main body can be opened.

  In recent years, in gaming halls, there has been a fraudulent act of illegally unlocking the main body of a gaming machine during business hours, illegally operating or replacing control devices provided on the back side of the main body, and acquiring many game media. Sometimes it is. Such unauthorized unlocking is usually performed by inserting a wire such as a wire through a gap between the game machine main body and the fixed frame, hooking the wire on a hook member of the locking device, and moving the wire in the unlocking direction. When an unauthorized unlocking operation is performed on the hook member, the hook member is detached from the locked portion, and the gaming machine body can be opened.

  As a means for preventing an illegal act on a control device or the like, there is a locking device for locking a mechanism plate or the like provided on the back side of the game machine main body to the game machine main body (for example, see Patent Document 1). If the mechanism board and the like are locked with respect to the game machine main body, even if the game machine main body is illegally opened, it is difficult for the control device and the like to be illegally acted.

  The base 621c of the upper back pack hook 621 extends downward, and its vertical section is set to be relatively longer than other portions. For this reason, the lower end of the base 621c of the back pack hook 621 is located considerably below the height of the head 621b of the back pack hook 621. Corresponding to this, the extension section 625 of the support plate 603 is also formed such that the vertical section is relatively longer than the other extension sections 624, 626. This is because the coil spring C1 is applied to the lower part of the root part 621c of the upper back pack hook part 621 as described later.

  Further, the mounting side wall portion 606 is formed with an oval guide hole 613, 614, 615 that is long in the vertical direction at a position slightly lower than the front frame set locking portions 610, 611, 612. Guide pins 616, 617, and 618 are fixed to the mounting plate 602 from the inside of the base frame 601 through the guide holes 613, 614, and 615.

  On the other hand, on the support plate 603, regulating protrusions 628, 629, and 630 for regulating the backward movement of the first sliding rod 605 are provided at three places in the vertical direction. The restricting projections 628, 629, and 630 have a function of increasing the stability of the mounting state of the first sliding rod 605 and a function as a guide part that enhances the stability of the sliding operation of the first sliding rod 605. . Therefore, the movement of the first sliding rod 605 in the front-rear direction is restricted by the mounting plate 602 and the regulating projections 628, 629, 630, and the guide pins 616, 617, 618 and a second sliding rod 635 described later. This allows the slider to slide up and down while restricting movement in the left and right directions.

  In the sliding range of the first sliding rod 605, positions where the lower edges of the guide holes 613, 614, 615 abut on the guide pins 616, 617, 618 are the front frame set locking portions 610, 611, 612. The board unit hook 620 and the back pack hooks 621 and 622 are positioned to be engaged with the corresponding engaged portions, namely, the front frame set hooks 17a, 17b and 17c, the receiving bracket 205 and the receiving bracket 204. . That is, this position corresponds to the locked position (reference position) of the first sliding rod 605. Therefore, the state in which the first sliding rod 605 is at this position corresponds to the locked state of 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.

  On the other hand, the positions where the upper edges of the guide holes 613, 614, 615 are in contact with the guide pins 616, 617, 618 are the front frame set locking portions 610, 611, 612, the board unit hook 620 and the back pack hook. 621 and 622 are positions where they are separated from the engaged portions. That is, this position corresponds to the unlock position of the first sliding rod 605. Accordingly, the state in which the first sliding rod 605 is in this position corresponds to the unlocked state of 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.

  Next, a portion related to a locking mechanism of the inner frame 12 as a main body locking means will be described. Inside the base frame 601, a second sliding rod 635 serving as a main component of the locking mechanism is disposed so as to be slidable in the vertical direction. The second sliding rod 635 forms a sliding member in the present embodiment.

  The second sliding rod 635 is composed of an elongated main body 636 disposed so as to overlap the support side wall 607 of the first sliding rod 605, and a pair of upper and lower members as an engaging portion for locking the inner frame 12. Inner frame hook portions 637 and 638.

  In a predetermined upper and lower section of the main body 636 corresponding to the bulge 603a of the support plate 603 (the bulge 607a of the support side wall 607), a bulge 636a bulging inward in the inner frame 12 is also provided. Is formed. However, the section where the bulge 636a of the main body 636 is formed is set shorter than the section where the bulge 607a of the support side wall 607 is formed, so that the sliding of the second sliding rod 635 is not hindered. Has become.

  The upper inner frame hook 637 of both inner frame hooks 637, 638 is provided at a position slightly below the upper front frame setting locking section 610 and above the upper back pack hook 621. On the other hand, the lower inner frame hook 638 is provided slightly below the lower front frame set hook 612 and at the lower end of the main body 636.

  The inner frame hooks 637 and 638 include bases 637a and 638a extending rearward from the rear edge of the main body 636, shafts 637b and 638b extending further rearward from the bases 637a and 638a, and the shafts. It comprises a substantially triangular head 637c, 638c provided to taper rearward on the rear end side of the portion 637b, 638b. The lower ends of the heads 637c and 638c protrude below the shafts 637b and 638b, and the protruding portions function as locking claws. Accordingly, when the inner frame 12 is locked, the inner frame hooks 637 and 638 are locked by the hook receiving portions 84 and 85 of the outer frame 11 on the lower side of the inner frame 12, and the opening of the inner frame 12 is restricted. .

  Extending portions 641 and 642 extending rearward are formed at the rear end edge of the support plate 603 corresponding to the inner frame hooks 637 and 638. The extension portions 641 and 642 are formed so as to overlap with the base portions 637a and 638a of the inner frame hook portions 637 and 638, and support the inner frame hook portions 637 and 638 in a state where the base portions 637a and 638a are almost always in contact with each other. are doing. In addition, the extension portions 641 and 642 are considered to be substantially in contact with the base portions 637a and 638a of the inner frame hook portions 637 and 638 in consideration of the thickness of the first sliding rod 605, and at the base thereof. The support plate 603 is formed with a step.

  The base portions 637a and 638a of the inner frame hooks 637 and 638 are formed with vertically long oval guide holes 643 and 644, respectively. Guide pins 645 and 646 are fixed to the extending portions 641 and 642 from the inside of the base frame 601 (outside of the inner frame 12) via these guide holes 643 and 644.

  The mounting side wall 606 of the first sliding rod 605 is provided with regulating projections 647 and 648 for regulating the movement of the second sliding rod 635 to the outside of the inner frame 12 at two locations in the vertical direction. I have. In the vicinity of the lower end of the mounting plate 602, a regulating protrusion 649 similar to the regulating protrusions 647 and 648 is provided. These restricting projections 647, 648, and 649 have a function as a guide part for improving the stability of the sliding operation of the second sliding rod 635, as well as a function for improving the stability of the mounting state of the second sliding rod 635. I have. Therefore, the movement of the second sliding rod 635 in the left-right direction is restricted by the supporting side wall portion 607 of the first sliding rod 605 and the restricting projections 647, 648, 649, and the mounting side wall of the first sliding rod 605 is provided. The guide pins 645 and 646 fixed to the part 606 and the support plate 603 restrict the movement in the front-rear direction, and can slide in the vertical direction.

  In the sliding range of the second sliding rod 635, the positions where the upper edges of the guide holes 643, 644 abut on the guide pins 645, 646 are determined by the inner frame hooks 637, 638 being the hook receiving portions 84, 85. Is the position to be engaged. That is, this position corresponds to the locked position (reference position) of the second sliding rod 635. Therefore, the state where the second sliding rod 635 is in this position corresponds to the locked state of the locking mechanism of the inner frame 12.

  On the other hand, the positions where the lower edges of the guide holes 643, 644 abut against the guide pins 645, 646 are the positions where the inner frame hooks 637, 638 are separated from the hook receiving portions 84, 85. That is, this position corresponds to the unlock position of the second sliding rod 635. Therefore, the state where the second sliding rod 635 is at this position corresponds to the unlocked state of the locking mechanism of the inner frame 12.

  The first sliding rod 605 and the second sliding rod 635 are urged upward or downward, respectively, by a coil spring C1 as urging means. More specifically, at the rear end edge of the main body 636 of the second sliding rod 635, the formation positions of the base 621 c of the back pack hook 621 of the first sliding rod 605 and the extension 625 of the support plate 603 are formed. , An extension 650 extending rearward is formed. One end of the coil spring C1 is hooked on the hook portion 653 provided on the extension portion 650, and the other end is provided on the first sliding rod 605 (the root portion 621c of the back pack hook portion 621). Part 654.

  Normally, the first sliding rod 605 is moved by the tensile force of the coil spring C1 at a position where the lower edges of the guide holes 613, 614, 615 are urged by the guide pins 616, 617, 618, that is, at a reference position. It is held in a state where downward movement is suppressed. On the other hand, the second sliding rod 635 is held in a position where the upper edges of the guide holes 643 and 644 are urged by the guide pins 645 and 646, that is, in the reference position, in which the upward movement is suppressed. . Then, when a cylinder lock 700 described later is operated, the first sliding rod 605 is displaced downward or the second sliding rod 635 is displaced upward against the tensile force of the coil spring C1. .

  Now, a cylinder lock 700 as a lock member is mounted on the wide portion 602a of the mounting plate 602. As shown in FIG. 20, a cylinder lock 700 includes a substantially cylindrical cylinder main body 701, a lock shaft 703 provided inside the cylinder main body 701 and having a keyhole 702 therein, and a cylinder main body 701 on the outer periphery of the cylinder main body 701. And an outer cylinder 704 provided.

  The cylinder lock 700 is fixed by screwing the flange portion 705 to the rear side of the mounting plate 602 with the cylinder main body 701 inserted into the mounting hole 602b of the mounting plate 602.

  A total of 16 through holes 706 are formed in the cylinder main body 701, eight upper and lower holes each communicating between the inside and the outside of the cylinder main body 701. Correspondingly, the lock shaft 703 is also formed with 16 through holes 708 communicating with the respective through holes 706. The keyhole 702 side of the through hole 708 is formed smaller in diameter than other parts so that a housing member such as a pin 714 described later does not fall into the keyhole 702.

  A spring 709 is housed in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and the pedestal 711 is connected to the other end. A plurality of spacers 712 and 713 and a pin 714 are accommodated in each through hole 708 so as to be supported by the pedestal 711. These pins 714, spacers 712, 713, and pedestal 711 can move up and down in the through holes 706, 708 by expansion and contraction of a spring 709. Among them, the pin 714 can be inserted into and retracted from the keyhole 702 through a small diameter portion of the through hole 708 on the keyhole 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. Then, in the state where the insertion of the key K is completed, each pin 714 is inserted into the groove of the key K as shown in FIG. 21, and the base end face of the pin 714 or one end face of the spacer 712 or 713 And the outer peripheral surface of the lock shaft 703 is flush. Thus, in the state where the insertion of the key K is completed, the lock shaft 703 can be rotated with the rotation operation of the key K. 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 keyhole 702.

  At the rear end of the lock shaft 703, a cam plate 720 as an engagement member for transmitting the turning operation of the key K inserted into the keyhole 702 to the first sliding rod 605 or the second sliding rod 635. Fixed.

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

  In accordance with this, a pair of upper and lower upper engaging holes 725 and a lower engaging hole 726 through 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 engaging holes 727 and 728 into which the engaging 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 engagement claws 720a and 720b.

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

  On the side of the first sliding rod 605, a section in which the lower engaging hole 726 located below the upper engaging hole 725 of the upper and lower engaging holes 725, 726 is formed. Is set relatively long. On the other hand, on the second sliding rod 635 side, the upper engagement hole 727 located above the vertical formation section of the lower engagement hole 728 located below of the two engagement holes 727 and 728. The formation section is set relatively longer. This is so that when the cam plate 720 slides one of the first sliding rod 605 or the second sliding rod 635 as described later, the upper engaging claw 720a or the lower engaging claw 720b does not contact the other. This is to prevent the other from sliding.

  Under the above configuration, as shown in FIG. 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, The tip of the upper engagement claw 720a is inserted into the upper engagement holes 725, 727 of the first sliding rod 605 and the second sliding rod 635, and the tip of the lower engagement claw 720b is The rod 605 and the second sliding rod 635 are inserted into the lower engagement holes 726, 728. Further, as described above, the cylinder lock 700 of the present embodiment is in a state where the lock shaft 703 and the cam plate 720 cannot be rotated (locked state) when the key K is not inserted into the keyhole 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 engagement claws 720a and 720b. For example, when a wire 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 by 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 performed by the engaging hole 725. 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, when the first sliding rod 605 takes the reference position, the front frame set hooks 17a, 17b, 17c are connected to the front frame set locked portions 610, 611, 612 as described above. The front frame set 14 is restricted from being opened.

  When unlocking the front frame set 14, the key K is inserted into the keyhole 702 of the cylinder lock 700 and rotated counterclockwise as 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 engagement claw 720a contacts the lower edge 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 clockwise.

  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 claw 720b is separated from both 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 is secured below the upper engagement hole 727 of the second sliding rod 635 through which the upper engagement claw 720a is inserted, the first engagement slide 720 is displaced downward. 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 between all the front frame set locking portions 610, 611, 612 and the front frame set hooks 17a, 17b, 17c is released, and the front frame set 14 is released. Opening is allowed. Further, when the force for operating the key K is released when the front frame set 14 is released, the first sliding rod 605 is pulled upward by the tensile force of the coil spring C1 and returns to the reference position. . Accordingly, the cam plate 720 and the lock shaft 703 also return to the reference positions.

  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 assumes the reference position, the inner frame hooks 637 and 638 are locked by 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 keyhole 702 of the cylinder lock 700, and is rotated clockwise 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 lower engaging claw 720b contacts the upper edge of the lower engaging hole 728 of the second sliding rod 635 (see FIG. 22C). However, since FIG. 22C is a view as viewed from the back side of the pachinko machine 10, the rotation direction of the cam plate 720 is counterclockwise.

  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 separated from both upper engaging holes 725 and 727 without affecting the first sliding rod 605 and the second sliding rod 635. At this time, a space for displacing the lower engaging claw 720b upward is secured above the lower engaging hole 726 of the first sliding rod 605 into which the lower engaging claw 720b is inserted. In the process of pushing up the moving rod 635, the lower engagement claw 720b does not come into contact with the first sliding rod 605, so that the 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 opening of the inner frame 12 is allowed. When the force of the hand operating the key K is released when the inner frame 12 is released, the second sliding rod 635 is pulled down by the tensile force of the coil spring C1, and returns to the reference position. Accordingly, the cam plate 720 and the lock shaft 703 also return to the reference positions.

  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 620 becomes the receiving bracket of the second control board unit 202. 205, and the opening of the second control board unit 202 is regulated.

  Similarly, in the locked state of the back pack unit 203, when the first sliding rod 605 assumes the reference position, the hooks 621 and 622 of the back pack are engaged with the receiving members 204 of the back pack unit 203, and the back pack unit 203 is locked. The opening of the unit 203 is regulated.

  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 keyhole 702 of the cylinder lock 700 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 engaging claw 720a contacts the lower edge of the upper engaging hole 725 of the first sliding rod 605. Thereafter, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes the first sliding rod 605 downward against the pulling force of the coil spring C1. The engagement with the receiving fitting 205 is released, and the opening of the second control board unit 202 is permitted. At the same time, the engagement between the back pack hooks 621 and 622 and the receiving fitting 204 is released, and the opening of the back pack unit 203 is opened. Is acceptable.

  As described above, in the present embodiment, when the key K is not inserted into the keyhole 702 of the cylinder lock 700, the sliding of the first sliding rod 605 and the second sliding rod 635 is regulated. 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 locking cannot be performed without using the key K. Therefore, 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 hooks 637 and 638 are hooked by the hook holes of the hook receiving portions 84 and 85. Even if the second sliding rod 635 is subjected to an upward external force by colliding with the lower edges of the parts 84a and 85a, 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 cylinder frame 700 is unlocked 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 lock position, the inner frame 12 is closed, and the heads 637 c, 638 c move the lower edges of the hook holes 84 a, 85 a of the hook receiving portions 84, 85. After that, the inner frame 12 is completely closed and the second sliding rod 635 is returned to the locking position. Alternatively, 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 heads 637c, 638c of the inner frame hooks 637, 638 hit the lower edges of the hook holes 84a, 85a of the hook receiving portions 84, 85, An upward external force 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 heads 637c, 638c of the inner frame hooks 637, 638 get over the lower edges of the hook holes 84a, 85a of the hook receiving portions 84, 85, the second sliding rod 635 applies the tensile force of the coil spring C1. To return to the original position. As a result, the inner frame hooks 637 and 638 are locked by the hook receiving portions 84 and 85. Of course, the locking of the front frame set 14, the second control board unit 202, and the back pack unit 203 can be performed by the same locking method.

  As described in detail above, 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 the number of parts is increased, the number of parts can be prevented from increasing, and the convenience such as workability during maintenance can be improved.

  Also, the respective hooks such as the inner frame hooks 637 and 638 are formed integrally 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 this configuration, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. Therefore, for example, even if an unlocking operation is directly performed on the first sliding rod 605 or the second sliding rod 635 with a wire or the like without using the key K, that is, even if an unauthorized unlocking operation is performed, Since the sliding rod 605 or the second sliding rod 635 is maintained at the locked position, the opening of the inner frame 12 or the like is not allowed. As a result, an improvement in protection performance against unauthorized unlocking using a wire or the like is achieved.

  Further, the back pack unit 203 is arranged so as to cover a control device such as the main control device 261 on the back side of the inner frame 12, 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 control device 261. As a result, the performance of protection against unauthorized unlocking using a wire or the like can be further enhanced.

  Further, in the present embodiment, since various control devices and various mechanisms are divided into three units, that is, the first control board unit 201, the second control board unit 202, and the back pack unit 203, the control unit and the backpack unit 203 are not used during maintenance. , Etc. can be improved.

  Further, by moving the first sliding rod 605, that is, by the same operation using the key K, all of the front frame set 14, the second control board unit 202, and the back pack unit 203 can be unlocked simultaneously. As a result, while simplifying the configuration of the locking device 600, the operation procedure is not complicated, and the convenience can be further improved.

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

  When the locking device 600 is fitted into the mounting groove 901, the support plate 603 and the flange 604 are substantially in contact with the side wall surface of the mounting groove 901. Therefore, 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. Therefore, even if a wire or the like is inserted from a gap between the front frame set 14 and the inner frame 12, the wire or the like is allowed to enter the back side of the base frame 601 on which the first sliding rod 605 and the like are disposed. It is difficult to operate the first sliding rod 605 and the like. As a result, the defense performance can be further improved.

  Further, in the present embodiment, since the locking device 600 is fixed from the front side of the inner frame 12 with the screws 904, the locking device 600 is not obstructed by various control devices, wiring, and the like provided on the rear side of the inner frame 12. In addition, it is possible to relatively easily perform an attaching operation, a replacing operation, and the like. As a result, convenience such as workability can be improved.

  Further, in the present embodiment, the outer frame 11 is formed with an extension wall portion 83 that covers the entire upper and lower sections corresponding to the locking device 600 from the rear side of the inner frame 12. Accordingly, it becomes more difficult to allow the wire or the like to enter from the rear side of the outer frame 11 and to operate the hooks such as the inner frame hooks 637 and 638 with the wire or the like. As a result, the defense performance can be further improved.

  Further, when the inner frame hooks 637 and 638 are engaged with the hook receiving portions 84 and 85, the peripheral walls of the hook receiving portions 84 and 85 surround the inner frame hooks 637 and 638. This makes it difficult to release the engagement between the inner frame hooks 637 and 638 and the hook receiving portions 84 and 85 by using a wire or the like. As a result, the defense performance can be further improved.

  Note that the present invention is not limited to the content 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. Have been. However, the configuration of the locking device 600 is not limited to the above embodiment. For example, only one of the second control board unit 202 and the back pack unit 203 may be configured to be locked to the inner frame 12, and a locking device according to this may be employed. Further, in addition to the second control board unit 202 and the back pack unit 203, three or more doors are locked on the back side of the inner frame 12, such as a configuration in which the first control board unit 201 is locked to the inner frame 12. It is also possible to adopt a locking device according to this configuration.

  (B) In the above embodiment, the locking mechanism of the front frame set 14 is provided with front frame set hooks 17a, 17b, and 17c each having a claw on the front frame set 14 side, and the claw is provided on the locking device 600 side. The front frame set locking portions 610, 611, and 612 that engage with the hooks are provided. However, a hook member having a claw portion is provided on the locking device 600 side, and A part may be provided. In this case, at the time of unlocking, the hook member on the locking device 600 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 reversed. That is, in the above embodiment, the inner frame hooks 637 and 638 are detached from the hook receiving portions 84 and 85 by, for example, sliding the second sliding rod 635 upward. A configuration in which the inner frame hook portions 637 and 638 are separated from the hook receiving portions 84 and 85 when the moving rod 635 slides downward may be employed.

  (D) In the above embodiment, the key K is inserted into the keyhole 702 of the cylinder lock 700, and the inner frame 12 is unlocked by rotating clockwise, and the front surface is rotated by rotating counterclockwise. The frame set 14, the second control board unit 202, and the back pack unit 203 are configured to be unlocked. However, the present invention is not limited thereto, and other unlocking operations may be performed as long as the unlocking operations of at least the inner frame 12 and the front frame set 14 are different. For example, the unlocking operations may be different from each other. As an example, while adopting a cylinder lock different from the cylinder lock 700 and having the third and fourth sliding rods, the inner frame 12 is unlocked by rotating in the clockwise direction, and The front frame set 14 is unlocked by rotating clockwise, and the second control board unit 202 is unlocked by rotating clockwise while the lock shaft is slid backward, A configuration in which the back pack unit 203 is unlocked by rotating counterclockwise while the lock shaft is slid to the rear side is exemplified.

  (E) At least in a state where the inner frame 12 is locked with respect to the outer frame 11, the locked state of the second control board unit 202 and the back pack unit 203 locked with respect to the inner frame 12 cannot be unlocked. When the unit 12 is opened, the locked state of both units 202 and 203 may be unlocked. This can further enhance the performance of protection against unauthorized unlocking using a wire or the like.

  (F) The configuration of each hook such as the inner frame hooks 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 formed integrally with the first sliding rod 605 and the second sliding rod 635. However, the present invention is not limited to this. The hook members 637, 638 and the like may be fixed to the first sliding rod 605 and the second sliding rod 635 so as not to be displaceable relative to each other by fixing means such as screws. The hook member constituting 638 or the like may be provided so as to be relatively displaceable with respect to the first sliding rod 605 and the second sliding rod 635.

  Further, in the above-described embodiment, the hook having a substantially triangular head tapered toward the tip is employed. However, the present invention is not limited to this. For example, the tip of the head may be substantially linear along the vertical direction. The formed hook may be adopted. The above embodiment employs a configuration in which the sliding displacement of the first sliding rod 605 and the second sliding rod 635 is regulated by the cam plate 720 when the key K is not inserted into the cylinder lock 700. If the inner frame 12 and the like in the open state are 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 and the like in the open state are closed without using the key K, the head ends of the hooks such as the inner frame hooks 637 and 638 are hooked. Even when it comes into contact with the engaged portions such as the portions 84 and 85, the above-mentioned problem does not occur because the first sliding rod 605 and the second sliding rod 635 do not receive a force in the unlocking direction.

  Further, the number of hooks such as the inner frame hooks 637 and 638 and the number of engaged portions corresponding to the hook receiving portions 84 and 85 are not limited to the numbers in the above embodiment. It may be one.

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

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

  (I) In the above embodiment, the locking device 600 is fixed from the front side of the inner frame 12 with the screw 904. However, the present invention is 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 901 by the locking claw or the like. Further, the locking device 600 may be fixed to the mounting groove 901 from the front side of the inner frame 12 by screws 904 from the rear side of the inner frame 12.

  (J) In the above embodiment, the outer frame 11 is formed with the extension 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. The configuration is not limited to this, and the extension wall portion 83 may be omitted, or the extension wall portion 83 may be formed only at a portion corresponding to a hook portion such as the inner frame hook portions 637 and 638.

  (K) In the above embodiment, in a state where the inner frame hooks 637 and 638 are engaged with the hook receivers 84 and 85, the peripheral walls of the hook receivers 84 and 85 surround the inner frame hooks 637 and 638.

The present invention is not limited to this, and the engaged portion (receiving metal fitting) with which the inner frame hooks 637 and 638 are engaged, and the cover member surrounding the inner frame hooks 637 and 638 engaged with the engaged portion. It is good also as a structure provided separately.

  (L) A cylinder lock different from the cylinder lock 700 may be employed. For example, when the key K is not inserted, the cylinder lock 700 of the above embodiment is locked, and the cam plate 720 cannot be displaced. When the first sliding rod 605 and the second sliding rod 635 are at the reference position, the tip of the upper engaging claw 720a is moved upward by the upper engaging pawl 720a. The holes 725 and 727 are inserted, and the tips of the lower engaging claws 720b are inserted into the lower engaging holes 726 and 728 of the first sliding rod 605 and the second sliding rod 635. Thereby, the sliding of the first sliding rod 605 and the second sliding rod 635 is regulated. However, the present invention is not limited to this, and a cylinder lock in which the cam plate 720 cannot be displaced may be employed. 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 second sliding rod 635 are not inserted. A configuration in which the sliding of the two sliding rods 635 is not restricted may be adopted.

  Further, a cylinder lock capable of changing a key code may be employed. As an example of a key code changing procedure, first, a current key is inserted into a keyhole while a predetermined reset pin is being pressed, and 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 keyhole, the key is turned in the opposite direction to the current key, and then the pressed state of the reset pin is released, and then the key is pulled out. By performing the above operations, a key code that matches the key to be newly set can be obtained. As a result, the keys can be unified for each game hall, and the keys can be changed periodically to prevent fraud.

  (M) It may be implemented as a pachinko machine of a type different from the above embodiment. In addition to the pachinko machine, the present invention may be implemented as an arrangement ball machine, various game machines such as a sparrow ball and the like, and a game machine of a type in which a slot machine and a pachinko machine are combined.
