It is locked on the front side, and the opening of the front frame set 14 is restricted.

  On the other hand, on the back pack unit 203, along the right side on the front side (see FIG. 4), a long receiving metal piece 204 as a locked portion is attached. In the receiving metal 204, rectangular locking holes 204a and 204b are formed at two locations on the upper and lower sides corresponding to the back pack collars 621 and 622.

  With the above configuration, when the back pack unit 203 is locked, the back pack collars 621 and 622 are located on the back side of the catch metal 204 via the locking holes 204 a and 204 b of the catch metal 204 of the back pack unit 203. It is locked and the opening of the back pack unit 203 is restricted.

  In the sliding range of the first sliding rod 605, the positions where the lower edge portions of the guide holes 613, 614, 615 abut on the guide pins 616, 617, 618 are the front frame set collar portions 610, 611, 612. And the back pack collar parts 621 and 622 are positions to be locked to the corresponding locked parts (the receiving metal member 17 and the receiving metal member 204). That is, this position corresponds to the locking position (reference position) of the first sliding rod 605. On the other hand, the positions where the upper edge portions of the guide holes 613, 614, 615 contact the guide pins 616, 617, 618 are located at the front frame set flange portions 610, 611, 612 and the back pack flange portions 621, 622. This is a position to be detached from the locking portion (the receiving metal member 17 and the receiving metal member 204). That is, this position corresponds to the non-locking position of the first sliding rod 605.

  Next, the part which concerns on the locking mechanism of the inner frame 12 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 bar 635 corresponds to the first locking member in the present embodiment.

  The second sliding bar 635 includes a long main body 636 disposed so as to overlap the supporting side wall 607 of the first sliding bar 605, and a pair of upper and lower inner frame hooks for locking the inner frame 12. 637, 638. The main body portion 636 corresponds to the sliding portion in the present embodiment.

  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 collar 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 are substantially triangular provided so as to taper rearward at the rear end side of the base portions 637a and 638a and base portions 637a and 638a extending rearward from the rear end edge portion of the main body portion 636. The heads 637b and 638b are shaped. The lower ends of the heads 637b and 638b protrude downward from the bases 637a and 638a, and the protruding portions function as locking portions (locking claws) as will be described later. Therefore, the inner frame collar parts 637 and 638 are locked to the receiving metal fittings 83 and 84 of the outer frame 11 on the lower side of the inner frame collar parts 637 and 638.

  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 extending portions 641 and 642 are formed so as to overlap the base portions 637a and 638a in almost the entire sliding range of the base portions 637a and 638a of the inner frame flange portions 637 and 638, and are always substantially the same as the base portions 637a and 638a. The base portions 637a and 638a are supported in the contact state. 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 restricting protrusions 647, 648, 649 that restrict the movement of the second sliding rod 635 to the outer side of the inner frame 12 at three positions in the vertical direction. It has been. The restricting protrusions 647, 648, 649 have a function as a guide portion for increasing the stability of the sliding operation of the second sliding rod 635 as well as a function of increasing the stability of the second sliding rod 635 in the mounted state. . 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. It is possible to slide in the vertical direction while restricting the movement in the front-rear direction by flange portions 651 and 652 provided at the rear edge of the portion 606 and the support plate 603.

  In the sliding range of the second sliding rod 635, the positions where the upper edge portions of the guide holes 643 and 644 contact the guide pins 645 and 646 are located at the inner frame flange portions 637 and 638 on the receiving metal fittings 83 and 84. It becomes the position to be locked. That is, this position corresponds to the locking position (reference position) of the second sliding rod 635. 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 receiving metal fittings 83 and 84. That is, this position corresponds to the non-locking position of the second sliding rod 635.

  With the above configuration, when the inner frame 12 is locked, the inner frame collar portions 637 and 638 are locked to the metal fittings 83 and 84 fixed to the inner side of the outer frame 11, and the opening of the inner frame 12 is restricted. The

  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 of the second sliding rod 635, the base 621a of the upper back pack collar 621 and the extending portion 625 of the support plate 603 of the first sliding rod 605 are formed. Corresponding to the position, an extending portion 650 extending rearward is formed. Then, one end of the coil spring C1 is hooked on the hook portion 653 provided in the extension portion 650, and the other end is provided on the first sliding rod 605 (the base portion 621a of the backpack collar portion 621). 654.

  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. 16, 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. 17, 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 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.

  As shown in FIG. 18, the cam plate 720 includes a pair of upper and lower upper engaging claws 720a and lower engaging claws 720b. These engaging claws 720a and 720b are formed at predetermined intervals in the rotational direction of the cam plate 720.

  Accordingly, a pair of upper and lower upper engagement holes 725 and 726 that can be engaged with the engagement claws 720a and 720b 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 that can be engaged with the engagement claws 720a and 720b 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. 18).

  Further, on the first sliding rod 605 side, the lower engagement hole 726 is set to have a longer vertical formation section than the upper engagement hole 725 out of both the engagement holes 725 and 726. On the other hand, on the second sliding rod 635 side, the upper engagement hole 727 has a longer vertical formation section than the lower engagement hole 728 of the two engagement holes 727 and 728. . 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.

  18A, 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 (locking position), so that the front frame set bar 610, 611, 612 is engaged with the bracket 17 of the front frame set 14. It is latched on the front surface side of the receiving bracket 17 through the stop holes 17a, 17b, 17c, and the opening of the front frame set 14 is restricted.

  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. 18B). However, since FIG. 18B 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 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 between all the front frame set collar portions 610, 611, and 612 and the receiving bracket 17 is released, and the opening of the front frame set 14 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, the second sliding rod 635 takes the reference position (locking position), so that the inner frame flange portions 637 and 638 are locked to the receiving fittings 83 and 84 of the outer frame 11, The opening of the inner frame 12 is restricted.

  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. 18C). However, since FIG. 18C is a view 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 flange portions 637 and 638 and the receiving fittings 83 and 84 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, locking and unlocking of the back pack unit 203 will be described in detail. In the locked state of the back pack unit 203, as in the case of the front frame set 14, the first slide bar 605 takes the reference position (locking position), so that the back pack bar parts 621 and 622 are in the back pack unit. Through the locking holes 204a and 204b of the receiving bracket 204 of 203, the back side of the receiving bracket 204 is locked, and the opening of the back pack unit 203 is restricted.

  When unlocking the back pack unit 203, the inner frame 12 is opened, and the key K inserted into the key hole 702 of the cylinder lock 700 is inserted in the front side of the pachinko machine 10 in the same manner as the front frame set 14. Turn counterclockwise as viewed from the top. 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 back pack collar 621, The engagement between 622 and the metal fitting 204 is released, and the opening of the back pack unit 203 is allowed.

  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, 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 opened inner frame 12 is closed without using the key K, the inclined portions of the heads 637b and 638b of the inner frame collar portions 637 and 638 collide with the receiving fittings 83 and 84, so Even if an upward external force is applied to the two sliding rods 635, the second sliding rod 635 does not slide upward, and the inner frame 12 cannot be closed. Therefore, when the inner frame 12 in the open state is locked, the cylinder lock 700 is operated using the key K, and the position where it is not obstructed by the receiving fittings 83 and 84, that is, the inner frame collars 637 and 638 are unlocked. With the second sliding rod 635 slid to the position, the inner frame 12 was closed, and the heads 637b and 638b passed over the receiving fittings 83 and 84, and the inner frame 12 was completely closed. Above, the method of returning the 2nd sliding rod 635 to a latching position is taken. 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 heads 637b and 638b of the inner frame collars 637 and 638 collide with the receiving fittings 83 and 84, an external force in the upward direction is applied to the second sliding collar 635. In addition, the second sliding rod 635 slides upward against the tensile force of the coil spring C1. Then, when the heads 637b and 638b of the inner frame collar portions 637 and 638 get over the receiving fittings 83 and 84, the second sliding collar 635 returns to the original position by the tensile force of the coil spring C1. As a result, the inner frame collar portions 637 and 638 are locked to the metal fittings 83 and 84. Of course, the front frame set 14 and the back pack unit 203 are also 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, and the locking mechanism of the back pack unit 203 are integrated into one locking device 600. In addition, it is possible to improve convenience such as improvement in workability during maintenance.

  In addition, the flanges such as the inner frame flanges 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. 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 locking position, the opening of the inner frame 12 or the like is not allowed. 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 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, and the locking mechanism of the back pack unit 203 are embodied by a single locking device 600. However, the configuration of the locking device 600 is not limited to the above embodiment. For example, in a configuration in which the front frame set 14 is integrally formed with the inner frame 12, the locking mechanism of the front frame set 14 is omitted, and a locking device including the locking mechanism of the inner frame 12 and the locking mechanism of the back pack unit 203 is provided. It may be adopted.

  (B) Regarding the locking mechanism of the front frame set 14, in the above embodiment, the front frame set collars 610, 611, 612 that serve as locking claws are provided on the locking device 600 side, and the front frame set 14 side has the aforementioned A receiving metal fitting 17 that engages with the front frame set collar 610 and the like is provided. However, the present invention is not limited thereto, and a hook member having a claw portion may be provided on the front frame set 14 side, and a sliding hook (first sliding hook 605) on the locking device 600 side may be engaged with the hook member. In this case, at the time of unlocking, the sliding rod on the locking device 600 side operates, so that the engaged state of both is released. Of course, the same applies to the locking mechanism of the back pack unit 203.

  (C) The sliding directions of the first sliding rod 605 and the second sliding rod 635 may be reversed. In other words, in the above embodiment, for example, the inner frame collar parts 637 and 638 are separated from the metal fittings 83 and 84 when the second sliding collar 635 slides upward. A configuration in which the inner frame collar portions 637 and 638 are detached from the metal fittings 83 and 84 by sliding the collar 635 downward may be employed.

  (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 and the back pack unit 203 are unlocked. It is good also as a structure from which not only this but three party unlocking operation differs. For example, by adopting a cylinder lock different from the cylinder lock 700 and providing a third sliding rod, the inner frame 12 is unlocked by rotating clockwise and rotated counterclockwise. The front frame set 14 is unlocked by the operation, and the back pack unit 203 is unlocked by rotating in the clockwise direction or the counterclockwise direction with the lock shaft slid to the back side. Also good.

  (E) At least in a state where the inner frame 12 is locked to the outer frame 11, the locked state of the back pack unit 203 locked to the inner frame 12 cannot be unlocked, and in a state where the inner frame 12 is opened The locked state of the back pack unit 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. It is good also as a structure fixed to the 1st sliding rod 605 and the 2nd sliding rod 635 so that relative displacement is not possible for the collar member which comprises 637,638 etc. with fixing means, such as a screw.

  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 metal fittings. Even when it comes into contact with the locked parts such as 83 and 84, 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-mentioned problem does not occur.

  Further, the number of hooks such as the inner frame hooks 637 and 638 and the corresponding hooked parts 83 and 84 corresponding to the hooks is not limited to the number of the above-described embodiments. It may be one.

  (G) 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.

  (H) You may implement as a different type of pachinko machine from the said 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, a game machine of a type in which a slot machine and a pachinko machine are integrated.
