  In addition, the base part 621c of the upper back pack collar part 621 extends downward, and the vertical formation section thereof is set to be relatively longer than other parts. For this reason, the lower end part of the root part 621c of the back pack collar part 621 is located considerably below the height position of the head part 621b of the back pack collar part 621. Correspondingly, the extending portion 625 of the support plate 603 is also set to have a relatively long vertical section compared to the other extending portions 624 and 626. This is because the coil spring C1 is hung on the lower portion of the root portion 621c of the upper back pack collar 621, as will be described later.

  In addition, in the attachment side wall portion 606, oval guide holes 613, 614, and 615 that are long in the vertical direction are formed at positions slightly below the front frame set locking portions 610, 611, and 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, the support plate 603 is provided with restriction projections 628, 629, and 630 for restricting the backward movement of the first sliding rod 605 at three locations in the vertical direction. The restricting protrusions 628, 629, and 630 have a function of improving the stability of the mounting state of the first sliding rod 605 and a function as a guide portion that increases the stability of the sliding operation of the first sliding rod 605. . Accordingly, the first sliding rod 605 is restricted in movement in the front-rear direction by the mounting plate 602 and the restricting projections 628, 629, 630, and the guide pins 616, 617, 618 and the second sliding rod 635 described later. Thus, it is possible to slide in the vertical direction while restricting the movement in the horizontal direction.

  In the sliding range of the first sliding rod 605, the positions where the lower edge portions of the guide holes 613, 614, 615 contact the guide pins 616, 617, 618 are the front frame set locking portions 610, 611, 612. The board unit collar 620 and the back pack collar 621, 622 are respectively engaged with the corresponding engaged portions, that is, the front frame set collars 17a, 17b, 17c, the receiving metal 205, and the receiving metal 204. . That is, this position corresponds to the locking position (reference position) of the first sliding rod 605. Therefore, the state in which the first sliding bar 605 is in this position corresponds to the locking 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 at which the upper edge portions 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 collar portion 620, and the back pack collar portion. 621 and 622 are positions to be detached from each engaged portion. That is, this position corresponds to the unlocking position of the first sliding rod 605. Therefore, the state in which the first sliding bar 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, the part which concerns on the locking mechanism of the inner frame 12 as a main body locking means is demonstrated. Inside the base frame 601, the 2nd sliding rod 635 used as the main component part of the said locking mechanism is arrange | positioned so that sliding is possible to an up-down direction. The second sliding rod 635 constitutes a sliding member in the present embodiment.

  The second sliding bar 635 includes a long main body 636 disposed so as to overlap with the support side wall part 607 of the first sliding bar 605, and a pair of upper and lower parts as engaging parts for locking the inner frame 12. Inner frame collar portions 637 and 638.

  In a predetermined upper and lower section of the main body portion 636 corresponding to the bulging portion 603a of the support plate 603 (the bulging portion 607a of the supporting side wall portion 607), a bulging portion 636a that similarly bulges inwardly of the inner frame 12 is formed. Is formed. However, the formation section of the bulging portion 636a of the main body 636 is set to be shorter than the formation section of the bulging portion 607a of the support side wall 607 so as not to hinder the sliding of the second sliding rod 635. It has become.

  Of the inner frame collars 637 and 638, the upper inner frame collar 637 is provided at a position slightly below the upper front frame set locking part 610 and above the upper backpack collar 621. On the other hand, the lower inner frame collar 638 is provided at a position slightly below the lower front frame set collar 612 and at the lower end of the main body 636.

  The inner frame collar portions 637 and 638 include base portions 637a and 638a extending rearward from the rear end edge portion of the main body portion 636, shaft portions 637b and 638b extending further rearward from the base portions 637a and 638a, and the shaft. It consists of substantially triangular heads 637c and 638c provided so as to taper rearward on the rear end side of the parts 637b and 638b. The lower end portions of the head portions 637c and 638c protrude downward from the shaft portions 637b and 638b, and the protruding portions function as locking claws. Therefore, in the locked state of the inner frame 12, the inner frame flange portions 637 and 638 are locked to the flange 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. .

  Corresponding to the inner frame flange portions 637 and 638, extending portions 641 and 642 extending rearward are formed on the rear end edge portion of the support plate 603. The extension parts 641 and 642 are formed so as to overlap with the base parts 637a and 638a of the inner frame collar parts 637 and 638, and support the inner frame collar parts 637 and 638 in a state of being substantially in contact with the base parts 637a and 638a at all times. is doing. The extending portions 641 and 642 take into account the thickness of the first sliding rod 605 so that the extending portions 641 and 642 are substantially in contact with the base portions 637a and 638a of the inner frame flange portions 637 and 638. The support plate 603 and the step are formed.

  In the base portions 637a and 638a of the inner frame collar portions 637 and 638, oval guide holes 643 and 644 that are long in the vertical direction are formed. Via these guide holes 643 and 644, guide pins 645 and 646 are fixed to the extending portions 641 and 642 from the inside of the base frame 601 (outside the inner frame 12).

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

  In the sliding range of the second sliding rod 635, the positions where the upper edge portions of the guide holes 643 and 644 are in contact with the guide pins 645 and 646 are the positions where the inner frame collar portions 637 and 638 are the collar receiving portions 84 and 85. It becomes a position engaged with. That is, this position corresponds to the locking position (reference position) of the second sliding rod 635. Therefore, the state in which the second sliding rod 635 is in this position corresponds to the locking state of the locking mechanism of the inner frame 12.

  On the other hand, the positions where the lower edge portions of the guide holes 643 and 644 are in contact with the guide pins 645 and 646 are positions where the inner frame flange portions 637 and 638 are separated from the flange receiving portions 84 and 85. That is, this position corresponds to the unlocked position of the second sliding rod 635. Therefore, the state in which the second sliding rod 635 is in 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 by a coil spring C1 as urging means. More specifically, at the rear end edge of the main body 636 in the second sliding rod 635, the formation position of the root portion 621c of the back pack collar 621 of the first sliding rod 605 and the extending portion 625 of the support plate 603 is formed. Corresponding to the above, an extending portion 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 backpack collar portion 621). Part 654 is hung.

  Due to the tensile force of the coil spring C1, the first sliding rod 605 normally has 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 the reference position. It is held in a state where the downward movement is suppressed. On the other hand, the second sliding rod 635 is held in a state in which the upper edge portion of the guide holes 643 and 644 is biased by the guide pins 645 and 646, that is, in a state in which upward movement is suppressed at the reference position. . 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. .

  A cylinder lock 700 serving as a lock member is attached to the wide portion 602a of the attachment plate 602. As shown in FIG. 20, the cylinder lock 700 includes a cylinder body 701 having a substantially cylindrical shape, a lock shaft 703 provided inside the cylinder body 701 and having a key hole 702 inside, and an outer periphery of the cylinder body 701. And an outer cylinder 704 provided.

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

  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 when 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 first sliding bar 605 takes the reference position as in the case of the front frame set 14, so that the board unit bar 620 receives the receiving bracket of the second control board unit 202. 205 is engaged, 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 first sliding bar 605 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, the key K inserted into the key hole 702 of the cylinder lock 700 after the inner frame 12 is opened and the front frame set 14 is opened. 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. Thereafter, as the cam plate 720 is further rotated, when the upper engagement claw 720a pushes down the first sliding rod 605 against the tensile force of the coil spring C1, the board 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, even if the inner frame 12 is illegally opened, it is difficult for the back pack unit 203 to perform an illegal act on the control device such as the main controller 261. As a result, the defense performance against unauthorized unlocking using a wire or the like can be further enhanced.

  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

  Further, by moving the first sliding bar 605, that is, by the same operation with 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, 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, 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.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (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. 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 corresponding to this may be employed. In addition to the second control board unit 202 and the back pack unit 203, three or more door bodies 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, regarding the locking mechanism of the front frame set 14, the front frame set collars 17a, 17b, and 17c having claw portions are provided 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 are engaged with the front portion are provided, but a hook member having a claw portion is provided on the locking device 600 side, and the front frame set 14 side is engaged with the claw portion. A part may be provided. 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 reversed. That is, in the above-described embodiment, for example, the second sliding rod 635 slides upward, so that the inner frame collar portions 637 and 638 are separated from the collar receiving portions 84 and 85. A configuration may be employed in which the inner frame collar parts 637 and 638 are detached from the collar receiving parts 84 and 85 by the sliding lever 635 sliding downward.

  (D) In the above embodiment, the inner frame 12 is unlocked by inserting the key K into the key hole 702 of the cylinder lock 700 and rotating in the clockwise direction, and rotating in the counterclockwise direction. The frame set 14, the second control board unit 202, and the back pack unit 203 are unlocked. Not only this but other unlocking operations may be sufficient as long as the unlocking operation of the inner frame 12 and the front frame set 14 is different. For example, it is good also as a structure from which each unlocking operation differs. As an example, while adopting a cylinder lock different from the cylinder lock 700 and providing the third and fourth sliding rods, the inner frame 12 is unlocked by rotating it in the clockwise direction. The front frame set 14 is unlocked by rotating clockwise, and the second control board unit 202 is unlocked by rotating clockwise with the lock shaft slid to the back side. Examples include 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.

  (E) At least in the state in which the inner frame 12 is locked to the outer frame 11, the locked state of the second control board unit 202 and the back pack unit 203 locked to the inner frame 12 cannot be unlocked. In a state where 12 is opened, the locked state of both units 202 and 203 may be unlocked. If it does in this way, the defense performance with respect to the unauthorized unlocking using a wire etc. can be raised further.

  (F) The configuration of the flanges such as the inner frame flanges 637 and 638 is not limited to the above embodiment. For example, in the above-described embodiment, the flanges such as the inner frame collars 637 and 638 are integrally formed with the first sliding collar 605 and the second sliding collar 635. 637, 638, etc. may be configured to be fixed so that they cannot be displaced relative to the first sliding rod 605 or the second sliding rod 635 by fixing means such as screws, or the inner frame flange portion 637, It is good also as a structure by which the collar member which comprises 638 grade | etc., Was provided so that relative displacement with respect to the 1st sliding rod 605 or the 2nd sliding rod 635 was possible.

  Moreover, in the said embodiment, although the collar part which has the substantially triangular head tapered toward the front-end | tip is employ | adopted, for example, the front-end | tip of a head is substantially linear along the up-down direction. You may employ | adopt the formed collar part. In the above embodiment, a configuration is adopted 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 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, when 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 head tips of the collars such as the inner frame collars 637 and 638 are received by the hook. Even when the engaged portions such as the portions 84 and 85 are contacted, the first sliding rod 605 and the second sliding rod 635 are not applied with a force in the unlocking direction, and thus the above-described problem does not occur.

  Further, the number of hooks such as the inner frame hooks 637 and 638 and the corresponding engaged parts such as the hooks 84 and 85 corresponding thereto is not limited to the number of the above-described embodiments. There 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. The mounting groove portion 901 is not limited. For example, you may employ | adopt the apparatus attaching part formed in convex shape along the right side part of the inner frame 12. As shown in FIG.

  (H) In the above-described embodiment, the base frame 601 constituting the outer shell of the locking device 600 has the mounting plate 602 fixed to the inner frame 12 and the rear edge from the inner edge of the inner plate 12 of the mounting plate 602. The supporting plate 603 protrudes and a flange portion 604 protrudes rearward from the 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 flange portion 604 may be omitted and the cross section may be 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. 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. Alternatively, the locking device 600 may be fixed from the back side of the inner frame 12 with screws 904 in a state where the locking device 600 is fitted into the mounting groove 901 from the front side of the inner frame 12.

  (J) In the above embodiment, the extending wall 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. Not only this but the extended wall part 83 is good also as a structure which abbreviate | omitted, and it is good also as a structure by which the extended wall part 83 was formed only in the part corresponding to collar parts, such as the inner frame collar parts 637 and 638.

  (K) In the above embodiment, in the state where the inner frame collar parts 637 and 638 are engaged with the collar receiving parts 84 and 85, the peripheral wall part of the collar receiving parts 84 and 85 surrounds the inner frame collar parts 637 and 638. It becomes a state. Not limited to this, an engaged portion (receiving metal fitting) with which the inner frame flange portions 637 and 638 are engaged, and a cover member surrounding the inner frame flange portions 637 and 638 engaged with the engaged portions. It is good also as a structure provided with another 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 locked 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 is engaged with the upper engagement of the first sliding rod 605 and the second sliding rod 635. The holes 725 and 727 are inserted, and the tips of the lower engagement claws 720 b are inserted into the lower engagement holes 726 and 728 of the first sliding rod 605 and the second sliding rod 635. Thereby, sliding of the 1st sliding rod 605 and the 2nd sliding rod 635 will be controlled. 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. Further, when the first sliding rod 605 and the second sliding rod 635 are in the reference position, the engaging claws 720a and 720b are not inserted into the engaging hole 725 and the like, and the first sliding rod 605 and the second sliding rod 605b are not inserted. A configuration in which sliding of the two sliding rods 635 is not restricted may be adopted.

  Moreover, you may employ | adopt the cylinder lock which can change a key code. As an example of the procedure for changing the key code, first, the current key is inserted into the keyhole while a predetermined reset pin is pressed, and then the key is pulled out. Then, while holding down 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 in the opposite direction to the current key. By performing the operation as described above, a key code suitable for a new key to be set can be obtained. As a result, the key can be unified for each game hall, and the key can be changed periodically to prevent fraud.
