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 where the upper edge portion of the guide holes 643 and 644 is urged by the guide pins 645 and 646, that is, in a state in which the 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 as an operation member is attached to the wide portion 602a of the attachment plate 602. The cylinder lock 700 includes a flange portion 705 that is fixed in contact with the back surface of the mounting plate 602, and a substantially cylindrical cylinder body 701 that extends through the mounting plate 602 forward from the flange portion 705 and has a keyhole. A cam plate 720 that is attached to a lock shaft (not shown) and that transmits the rotation of the key inserted into the keyhole to the first sliding rod 605 or the second sliding rod 635 is fixed.

  As shown in FIG. 16, 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. 16A).

  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.

  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, a key is inserted into the key hole of the cylinder lock 700 and rotated counterclockwise as viewed from the front side of the pachinko machine 10 (see FIG. 1) (key operation To do). 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. 16B). However, since FIG. 16B 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 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 hand operating the key 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 (lock shaft) also returns 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.

  When unlocking the inner frame 12, a key is inserted into the key hole of the cylinder lock 700 and 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 engagement claw 720b comes into contact with the upper edge portion of the lower engagement hole 728 of the second sliding rod 635 (see FIG. 16C). However, since FIG.16 (c) is the figure seen from the back side of the pachinko machine 10, the rotation direction of the cam board 720 is a 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 is loosened when the inner frame 12 is released, 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 (lock shaft) also returns 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 inserted into the key hole of the cylinder lock 700 is viewed from the front side of the pachinko machine 10 in the same manner as the front frame set 14. And turn it counterclockwise. 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.

  Now, in the present embodiment, the configuration is such that the opening of the inner frame 12 and the front frame set 14 (the back pack unit 203) is restricted in a state where the external power supply is stopped. Hereinafter, such a configuration will be described with reference to the drawings. FIG. 17 is a perspective view showing a peripheral portion of the locking solenoid 411 attached to the front surface of the attachment plate 602. FIG. 18 is an enlarged view showing a peripheral portion of the locking solenoid 411 in which the plunger 412 is immersed. FIG. 19 is an enlarged view showing a peripheral portion of the locking solenoid 411 in a state where the plunger 412 protrudes.

  As shown in FIGS. 13 and 14, the mounting plate 602 has a sliding hole 401 penetrating in the front-rear direction between the upper front frame set collar 610 and the middle front frame set collar 611. It is formed along the inner surface of 603.

  As shown in FIGS. 15, 17, etc., the sliding hole 401 has a first support piece 402 extending forward from the support side wall 607 of the first sliding rod 605 and a front from the second sliding rod 635. A second support piece 403 extending in the direction is inserted. The first support piece 402 and the second support piece 403 are formed with a first engagement hole 404 and a second engagement hole 405 penetrating in the left-right direction. When the key operation (unlocking operation of the operation member) of the cylinder lock 700 is not performed, the first engagement hole 404 and the second engagement hole 405 are in a state of communicating in the left-right direction.

  The vertical width of the sliding hole 401 is larger than the vertical width of the first support piece portion 402 and the second support piece portion 403, and the first slide rod 605 and the second slide rod 635 are slid in the vertical direction. It is configured not to disturb the movement. That is, in the sliding hole 401, a space that allows the displacement of the first support piece 402 accompanying the downward sliding of the first sliding rod 605 below the first support piece 402 is secured, and Above the second support piece portion 403, a space that allows the displacement of the second support piece portion 403 accompanying the upward sliding of the second sliding rod 635 is secured. Note that the mounting side wall portion 606 is located above and below the first support piece portion 202 (in the configuration of the present embodiment, so as not to prevent vertical sliding of the first sliding rod 605 and the second sliding rod 635). Is also cut out (see FIGS. 14 and 15).

  As shown in FIG. 18 and the like, on the right side of the first support piece 402 and the second support piece 403 when viewed from the front side of the pachinko machine 10, a plunger 412 as a drive part protrudes downward. The locking solenoid 411 is fixedly attached to the front surface of the mounting plate 602 in the direction. The locking solenoid 411 in the present embodiment is energized by being supplied with electric power, so that the plunger 412 is immersed in the solenoid body (the protruding length of the plunger 412 is shortened), and the electric power supply is stopped and de-excited. By adopting the state, a type in which the plunger 412 protrudes from the solenoid body (the protrusion length of the plunger 412 becomes longer) is adopted. In addition, a spring that applies force in a direction to protrude with respect to the plunger 412 is provided inside the locking solenoid 411, and in the event of a power failure, the plunger 412 protrudes greatly from the solenoid body due to the action of the spring. It is said.

  As shown in FIG. 9, the locking solenoid 411 is electrically connected directly to the power supply unit 541. That is, when power is supplied to the power supply unit 541 from the outside, + 12V power is immediately supplied to the locking solenoid 411, and the locking solenoid 411 is immediately brought into an excited state. On the other hand, when the power supply to the power supply unit 541 is stopped, the locking solenoid 411 is immediately brought into a non-excitation state.

  A movable member 421 is provided below the locking solenoid 411 so as to be rotatable with respect to the front surface of the mounting plate 602. The movable member 421 extends in the left-right direction and can contact the tip of the plunger 412. The first piece 423 can contact the tip of the plunger 412, and the first piece from the left end of the first piece 423 when viewed from the front side of the pachinko machine 10. A second piece 424 extending downward (lower right in FIG. 18) at an angle of 423 and 423, and an inner frame extending perpendicularly from the tip of the second piece 424 to the second piece 424. 12 as an insertion portion 425 projecting inwardly (lower left in FIG. 18), and a state maintaining means projecting upward from the distal end of the insertion portion 425 so as to be orthogonal to the insertion portion 425 (upper left in FIG. 18) The claw part 426 is provided. A rotation hole 428 penetrating in the front-rear direction is formed at the boundary between the first piece portion 423 and the second piece portion 424, and the sliding protrusion 429 inserted into the rotation hole 428 is immersed. The plunger 412 is fixed to the front surface of the mounting plate 602 at a position corresponding to the lower left side of the plunger 412 in the state (lower than the distal end portion of the plunger 412 in the immersed state and inward of the inner frame 12).

  In addition, a coil spring C3 is provided between the first piece 423 of the movable member 421 and the locking solenoid 411 (fixing fitting for fixing the locking solenoid 411 to the mounting plate 602). Thus, the first piece 423 and the plunger 412 are basically always in contact with each other regardless of the state in which the plunger 412 appears and disappears. As for the relationship between the forces acting on the plunger 412, the holding force of the locking solenoid 411 in the excited state is the strongest, and then the elastic force (pushing force) of the spring built in the locking solenoid 411 is strong, and the coil spring The pulling force by C3 is the weakest.

  In the present embodiment, as shown in FIG. 18, the first piece 423 extends substantially horizontally when the plunger 412 is immersed. In this state, the insertion portion 425 and the claw portion 426 are positioned on the outer side of the inner frame 12 (right side in FIG. 18) than the second support piece portion 403, and the insertion portion 425 and the claw portion 426 are the first and first portions. 2 It is in the state where it is not inserted in engagement holes 404 and 405.

  On the other hand, as shown in FIG. 19, in the protruding state of the plunger 412, the first piece 423 is pushed by the plunger 412, and the right end of the first piece 423 is inclined downward. It will be in the state rotated about 45 degree | times clockwise from the state of 18. FIG. In this state, the insertion portion 425 extends substantially horizontally, and the insertion portion 425 is inserted into the first engagement hole 404 and the second engagement hole 405. Furthermore, the claw portion 426 is positioned on the inner side of the inner frame 12 (the right side in FIG. 19) than the first support piece portion 402.

  In this embodiment, the locking solenoid 411, the movable member 421, and the coil spring C3 constitute an opening restricting means, and the locking solenoid 411 and the coil spring C3 constitute a driving means. The plunger 412 is in an immersive state, and the state in which the insertion portion 425 of the movable member 421 is pulled out of the first engagement hole 404 and the second engagement hole 405 corresponds to the first state of the opening restriction means. The position (posture) of the movable member 421 when the plunger 412 in the state is in contact with the first piece 423 corresponds to the first position. Furthermore, the state in which the plunger 412 is in the protruding state and the insertion portion 425 of the movable member 421 is inserted through the first and second engagement holes 404 and 405 corresponds to the second state of the opening restricting means, and the protruding state The position (posture) of the movable member 421 when the plunger 412 and the first piece 423 are in contact with each other corresponds to the second position.

  In addition, in the state shown in FIG. 19 in which the insertion portion 425 is inserted through the first and second engagement holes 404 and 405, the portion that is above the claw portion 426 projects forward from the mounting plate 602, A rotation restricting protrusion 431 is provided as a state maintaining means capable of contacting. That is, even if the movable member 421 tries to further rotate in the clockwise direction from the state shown in FIG. 19 (the state where the insertion portion 425 extends substantially horizontally), the claw portion 426 comes into contact with the rotation restricting projection 431 and beyond. Will be restricted. Accordingly, in the state where the insertion portion 425 is inserted through the first and second engagement holes 404 and 405, for example, by applying an upward force to the second sliding rod 635, the second engagement hole 405 is applied. Even when the lower edge portion of the claw portion abuts against the lower side portion of the insertion portion 425 and the insertion portion 425 is pushed upward, the claw portion 426 abuts against the rotation restricting projection 431, so that the movable member 421 rotates. It will be regulated.

  As shown in FIGS. 3 and 4, the right side of the inner frame 12 and the front frame set 14 (the side on the front side in FIG. 3) has a locking solenoid 411, a movable member 421, a first support piece 402, In correspondence with the second support piece 403 (hereinafter, these members are collectively referred to as an opening restriction mechanism), an installation hole 441 penetrating in the front-rear direction and an accommodation recess 442 recessed forward are formed. ing. In the attached state of the locking device 600, the opening restriction mechanism is housed in the housing recess 442 through the installation hole 441.

  The installation hole 441 and the housing recess 442 are sized to cover the locking solenoid 411, the movable member 421, and the sliding hole 401 formed in the mounting plate 602. 605 and the second sliding rod 635 are not hindered from sliding. The lateral width is substantially the same as the lateral width of the mounting plate 602, and the installation hole 441 is almost completely covered by the mounting plate 602 when the locking device 600 is attached. That is, since there is almost no gap between the installation hole 441 and the mounting plate 602, it is difficult or impossible to contact the locking solenoid 411 and the movable member 421 when the locking device 600 is mounted. It has become.

  Next, the movement of the locking solenoid 411 and the like when the power is turned on / off will be described with reference to the drawings. In addition, since there are a large number of gaming machines installed in the gaming hall, generally, the power switch of each gaming machine is always turned on, and the power is turned on and off collectively by the centralized power supply (distribution panel) of the hall. It is designed to switch. In other words, each gaming machine is activated when the power switch of the switchboard is turned on, and the power of each gaming machine is turned off when the power switch of the switchboard is turned off.

  When power is supplied to the pachinko machine 10, the locking solenoid 411 is energized and the plunger 412 is immersed. At this time, the movable member 421 rotates counterclockwise from the state of FIG. 19 to the state of FIG. 18 by the biasing force of the coil spring C3, and the insertion portion 425 has the first engagement hole 404 and the second engagement hole 405. You will get out of it. Accordingly, the first support piece 402 and the second support piece 403 (peripheral portions of the first engagement hole 404 and the second engagement hole 405) and the insertion portion 425 of the movable member 421 do not come into contact with each other. The first sliding rod 605 and the second sliding rod 635 can be slid. For this reason, as described above, the front frame set 14 (back pack unit 203) or the inner frame 12 is unlocked in accordance with the key operation of the cylinder lock 700.

  On the other hand, when the power supply to the pachinko machine 10 is stopped, the locking solenoid 411 is de-energized and the plunger 412 is in the protruding state. At this time, the movable member 421 is pushed by the plunger 412, and rotates clockwise from the state of FIG. 18 to the state of FIG. 19 against the coil spring C3, and the insertion portion 425 is engaged with the first and second engagements. The holes 404 and 405 are inserted.

  When the insertion portion 425 is inserted through the first and second engagement holes 404 and 405 in this manner, even if the first slide rod 605 is slid downward, When the edge comes into contact with the insertion portion 425 of the movable member 421, the sliding is restricted. Further, even if the second sliding rod 635 is slid upward, the sliding of the second engaging hole 405 is restricted by contacting the lower side of the insertion portion 425. .

  Incidentally, when the insertion portion 425 is pushed downward by the upper edge portion of the first engagement hole 404, a force is applied to the movable member 421 in the counterclockwise direction of FIG. Since 426 is hooked on the left side surface (the surface on the inner side of the inner frame 12) of the first support piece portion 402, its rotation is restricted. Further, when the insertion portion 425 is pushed upward by the lower side portion of the second engagement hole 405, a force is applied to the movable member 421 in the clockwise direction of FIG. By abutting on the rotation restricting protrusion 431, the rotation is restricted.

  As described above in detail, in the present embodiment, the first and second engagement holes formed in the first and second support piece portions 402 and 403 in a state where the power supply to the pachinko machine 10 is stopped. The insertion portion 425 is inserted into 404 and 405. As a result, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted, and the front frame set collar portions 610, 611, 612, the back pack collar portions 621, 622, and the inner frame collar portions 637, 638. Displacement to the non-locking position side is restricted. For this reason, when the power supply is stopped, for example, during business hours such as at night, the wire rod that has entered the pachinko machine 10 is hooked on the inner frame collars 637, 638, etc. Even if the obtained combination key is used, the inner frame 12 and the front frame set 14 (the back pack unit 203) in the locked state cannot be brought into the unlocked state. Therefore, without realizing that an illegal act has been performed on the inside of the pachinko machine 10 such as illegally replacing the control device, the game is played in that state, and the game hall suffers a great deal of damage. The situation can be prevented, and as a result, the defense performance against unauthorized opening of the inner frame 12 and the front frame set 14 (back pack unit 203) can be enhanced.

  Also, for example, sliding of the first sliding rod 605 and the second sliding rod 635 can be restricted by directly inserting the plunger of the locking solenoid into the first and second engagement holes 404 and 405. However, in this case, when the first sliding rod 605 and the second sliding rod 635 are forcibly displaced while the power supply is stopped, a load is directly applied to the plunger. As a result, the plunger may be deformed or the locking solenoid may be broken. In this regard, according to the present embodiment, since the insertion portion 425 of the movable member 421 provided separately from the locking solenoid 411 is inserted into the first and second engagement holes 404 and 405, the locking solenoid 411 is provided. Can be prevented from being deformed or damaged. As a result, a commercially available solenoid can be mounted almost as it is, and costs can be reduced and productivity can be improved.

  Furthermore, in this embodiment, the locking solenoid 411 and the movable member 421 are provided on the front surface of the mounting plate 602, and the locking solenoid 411 and the movable member 421 cannot be contacted unless the locking device 600 is removed from the inner frame 12. It is difficult to contact. Accordingly, it is possible to suppress an illegal act such as applying a force directly to the locking solenoid 411 or the movable member 421 with a wire or the like that has entered the pachinko machine 10 to cause the locking solenoid 411 to be in an immersive state.

  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, when the power supply is stopped, the plunger 412 of the locking solenoid 411 protrudes and is pushed by the plunger 412 to rotate the movable member 421, so that the insertion portion 425 is the first and first insertion portions. The opening of the inner frame 12 and the front frame set 14 (the back pack unit 203) is restricted by being inserted into the two engagement holes 405, but is particularly limited to such a configuration. It is not a thing. That is, it is sufficient that the opening of the inner frame 12 is restricted at least when the power supply is stopped. For example, the first support piece portion 402 and the claw portion 426 can be omitted (this In this case, the front frame set 14 and the back pack unit 203 can be opened by operating the key of the cylinder lock 700 even when the power supply is stopped).

  For example, by providing a locking solenoid 411 in a lateral direction so that the plunger 412 protrudes inward of the inner frame 12, and inserting the distal end portion of the plunger 412 into the first and second engagement holes 404 and 405, It is good also as a structure which controls opening | release of the inner frame 12 and the front frame set 14. FIG. In this case, the protruding and retracting direction of the plunger 412 which is a member inserted through the first and second engaging holes 404 and 405 and the sliding directions of the first sliding rod 605 and the second sliding rod 635 are substantially orthogonal. Will be. For this reason, the plunger 412 enters an immersive state by being pushed by the first and second support pieces 402 and 403 (peripheries of the first and second engagement holes 404 and 405), and the first slide is made. It is possible to prevent a situation in which sliding of the moving rod 605 and the second sliding rod 635 is allowed. Therefore, the effect of enhancing the defense performance against unauthorized unlocking is reliably exhibited.

  Further, for example, as shown in FIG. 20, the back surface of the mounting plate 602 is of the same type as the locking solenoid 411 of the above embodiment (excited when the pachinko machine 10 is activated and the plunger 802 is sunk, and built in when the power is cut off. The plunger 802 protrudes by the action of the spring thus provided) and the plunger 802 is provided so that the plunger 802 protrudes and protrudes from the right side portion (the left edge in FIG. 20), and the tip of the plunger 412 It is good also as a structure which controls the opening of the inner frame 12 by making a part into the recessed part 805 formed in the inner surface of the outer frame 11 (state shown with the dashed-two dotted line of FIG. 20). In this case, in a state where the power supply is stopped, a wire rod or the like that has entered the pachinko machine 10 is hooked on the inner frame collars 637 and 638 to directly apply force, or an illegal key is obtained to obtain a cylinder lock. The inner frame 12 in the closed state even when the inner frame collars 637 and 638 are displaced to the non-locking position side (upper side) (that is, the inner frame 12 is unlocked) by performing 700 key operations. Can not be released. Therefore, basically the same operational effects as those of the above embodiment are achieved. From the viewpoint of durability or the like, rather than directly engaging the plunger 802 with the recess 805 (outer frame 11), an engaging portion as a separate member is fixed to the tip of the plunger 802, It is desirable to provide an interlocking member that interlocks with the plunger 802 to engage the engaging portion or interlocking member with the recess 805.

  A locking solenoid may be provided on the outer frame 11 side. That is, a locking solenoid is provided on the outer frame 11 so that the plunger protrudes from the inner side surface of the outer frame 11, and the distal end portion of the plunger is inserted into a recess provided on the side surface or the back side of the inner frame 12. It is good also as a structure which controls the opening of the inner frame 12 by setting it as a state.

  Furthermore, instead of the solenoid 411 and the movable member 421 in the above-described embodiment, for example, a configuration as illustrated in FIGS. 21A and 21B may be employed. More specifically, an upper position of a locking solenoid 811 of the same type as the locking solenoid 411 of the above embodiment, which is provided on the front surface of the mounting plate 602 and the plunger 812 protrudes upward when power supply is stopped. A rack member 813 having a plurality of teeth protruding leftward when viewed from the front side of the pachinko machine 10 is provided so as to be slidable in the vertical direction. The rack member 813 is fixed to the distal end portion of the plunger 412 of the locking solenoid 411, and the rack member 813 slides up and down when the plunger 412 protrudes and retracts. The rack member 813 is formed with a vertically long guide hole 814, and a guide protrusion 815 fixed to the front surface of the mounting plate 602 is inserted into the guide hole 814 in an engaged state.

  A pinion member 821 having a plurality of teeth that mesh with the rack member 813 is provided on the left side of the rack member 813 when viewed from the front side of the pachinko machine 10 so as to be rotatable with respect to the front surface of the mounting plate 602. The pinion member 821 is configured by two gears of different sizes fixed on the same shaft being overlapped in the front-rear direction, and is positioned in the rear of the two gears and substantially in contact with the front surface of the mounting plate 602 And a small wheel portion 823 that is fixed to the front side (front side in FIG. 21) of the large wheel portion 822 and has a smaller diameter and a smaller number of teeth than the large wheel portion 822. . In the present embodiment, the pinion member 821 is designed to mesh with the rack member 813 in the small wheel portion 823.

  Further, an engaging portion 831 as a movable member is provided above the pinion member 821 so as to be slidable in the left-right direction. A long guide hole 832 is formed on the engaging portion 831 on the left and right, and a guide protrusion 833 fixed to the front surface of the mounting plate 602 is inserted into the guide hole 832 in an engaged state. The engaging portion 831 has a plurality of teeth that mesh with the large wheel portion 822 at the lower side thereof. For this reason, the engaging portion 831 slides in the left-right direction as the pinion member 821 rotates.

  More specifically, as described above, the pinion member 821 meshes with the rack member 813 connected to the plunger 812 of the locking solenoid 411, and the plunger 812 protrudes upward as shown in FIG. In this case, the pinion member 821 rotates in the counterclockwise direction in the drawing and the engaging portion 831 slides to the left. On the other hand, as shown in FIG. 21 (b), when the plunger 812 is immersed downward, the pinion member 821 rotates in the clockwise direction in FIG. 21 and the engaging portion 831 moves to the right. Slide. The rack member 813 and the engaging portion 831 are configured so as not to interfere with each other's sliding.

  Then, the engaging portion 831 is configured to be inserted into the first and second engaging holes 404 and 405 in a state where the plunger 412 protrudes as shown in FIG. Even in the case of adopting the above-described configuration, the same effects as those of the above-described embodiment can be obtained. In addition, it is good also as providing the support protrusion which can be slidably contacted with the upper side part and lower side part of the engaging part 831. FIG. In this case, sliding of the engaging portion 831 is guided by the support protrusion, and when the first and second engaging holes 404 and 405 come into contact with the upper edge portion and the lower edge portion, the engaging portion 831 is moved. It can be supported and deformation of the engaging portion 831 can be prevented. It should be noted that a force is applied to the left side of FIGS. 21A and 21B with respect to the engaging portion 831 so that the engaging portion 831 can be more smoothly inserted into the first and second engaging holes 404 and 405 when the power is turned off. An elastic body (such as a spring) that applies a force may be provided, or an elastic body that applies an upward force to the rack member 813 may be provided.

  In addition, for example, a permanent magnet may be incorporated as the locking solenoid 411, and a solenoid in which the plunger 412 is held in the same position even after a power failure may be employed. In this case, a circuit for projecting the plunger 412 and a circuit for immersing the plunger 412 are provided, and the plunger 412 is caused to appear and disappear by performing switching control such as which circuit is supplied with power. . That is, when the pachinko machine 10 is started, power is supplied to the circuit for causing the plunger 412 to protrude, and when the power is turned off (when the power switch is turned off and during a power failure), the circuit for immersing the plunger 412 is used. The power supply to the locking solenoid 411 may be completely cut off after the power is supplied (the power supply may be provided to supply the power) and the plunger 412 is immersed.

  In addition to the locking solenoid 411, a lock mechanism that can hold the position of the plunger 412 during a power failure may be provided. For example, a hole may be formed in the distal end portion of the plunger 412 of the locking solenoid 411, and a restriction piece configured to be slidable by a solenoid or the like and inserted into the hole when the power is turned off may be provided.

  In any of the above examples, a solenoid is used. However, in addition to the solenoid, for example, a motor (stepping motor), a cylinder mechanism, or the like is used to open the inner frame 12 in a state where power supply is stopped. You may comprise so that it may be regulated. Different types of solenoids (types in which the plunger protrudes when energized or rotary solenoids) may be used. In addition, in the above-described embodiment, a solenoid of a type that incorporates a spring that applies force to the plunger 412 is employed as the locking solenoid 411. However, the spring is provided in an exposed state outside the solenoid body. Any type of solenoid may be employed. In this case, it is good also as providing a diameter-expansion part in a plunger and arrange | positioning a spring between the said diameter-expansion part and a solenoid main body.

  (B) In the above embodiment, the locking solenoid 411 is provided on the front surface of the mounting plate 602, but the locking solenoid 411 may be provided on the rear surface of the mounting plate 602. In this case, a cover member that covers the locking solenoid 411 may be provided. By providing the cover member, it is possible to prevent the act of retracting the plunger 412 by applying a direct force to the plunger 412 as in the case where the locking solenoid 411 is provided on the front surface of the mounting plate 602. In particular, when a screw for attaching the cover member to the attachment plate 602 is attached from the front side of the attachment plate 602, the cover member cannot be removed unless the locking device 600 is removed. To be played.

  (C) 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. Further, the locking mechanism of the back pack unit 203 (the back pack collars 621 and 622, the extending parts 625 and 626, and the metal fitting 204) may be omitted.

  (D) Moreover, in the said embodiment, the front frame set collar part 610,611,612 for locking the front frame set 14 with respect to the 1st sliding rod 605 and the 2nd sliding rod 635, respectively, backpack unit The back pack collars 621 and 622 for locking 203 and the inner frame collars 637 and 638 for locking the inner frame 12 are provided fixedly (relative displacement is impossible). It is not limited. For example, the inner frame collar parts 637 and 638, the front frame set collar parts 610, 611 and 612, and the back pack collar parts 621 and 622 can be moved relative to the first sliding collar 605 and the second sliding collar 635. It is good also as providing in.

  Hereinafter, the example of an aspect shown in FIG.22, FIG.23, FIG.24 is demonstrated. FIG. 22 is a perspective view showing the lower part of the locking device 900. FIG. 23 is a rear view showing the lower part of the locking device 900. FIG. 24A is a bottom view showing the opening restriction unit 931, and FIG. 24B is an exploded view of FIG. 22 and 23 show a state where both the inner frame collar member 912 and the front frame set locking member 913 are in the locking position. 22 and 23, for the sake of convenience, only the lower portion of the locking device 900 is shown, and the upper configuration is not shown.

  First, the basic structure of the locking device 900 shown in FIG. 22 etc. is demonstrated. The locking device 900 includes a mounting plate 902 that abuts and is fixed to the back surface of the inner frame 12 along the right side portion (the left side portion in the rear view) of the inner frame 12, and the inner frame 12 inner side of the mounting plate 902. A base frame 901 having a substantially L-shaped cross section including a support plate 903 extending rearward from the edge (right side in FIGS. 22 and 23) is provided.

  As shown in FIG. 23, the mounting plate 902 is formed with a pair of upper and lower insertion holes 902a. Note that a communication hole (not shown) is formed in the inner frame 12 (resin base 38) at a position facing the insertion hole 902a when the locking device 900 is attached. When the front frame set 14 is closed, the front frame set collar portion 14a extending to the back side of the front frame set 14 enters the insertion hole 902a through the communication hole.

  Further, the locking device 900 is provided on a sliding rod 911 slidably provided along the inner surface (left surface in FIG. 23) of the support plate 903, and on the inner surface (left surface in FIG. 23) of the sliding rod 911. And a pair of upper and lower inner frame flange members 912 that are slidable in the vertical direction. The sliding rod 911 and the inner frame rod member 912 are always biased downward by a pair of upper and lower coil springs C1. In the present embodiment, the inner frame collar member 912 constitutes the second locking member, and the lower position corresponds to the locking position and the upper position corresponds to the non-locking position in the sliding range of the inner frame collar member 912. To do.

  When the inner frame 12 is in the closed state, the inner frame collar member 912 is locked to the upper side portion of the receiving bracket (similar to the receiving brackets 83 and 84 in the above embodiment) fixed to the inner side of the outer frame 11. The Thereby, the inner frame 12 is locked to the outer frame 11. The movement of the inner frame collar member 912 when closing the inner frame 12 will be briefly described. The inner frame collar member 912 is pushed upward by contacting the receiving metal fitting, and resists the biasing force of the coil spring C1. And then slide toward the upper non-locking position. Thereafter, the coil spring C1 returns to the lower locking position by the urging force of the coil spring C1 and is locked to the receiving metal fitting.

  The pair of upper and lower inner frame collar members 912 are configured to slide upward simultaneously at the same time as the sliding collar 911 slides upward. On the other hand, the sliding rod 911 is configured not to slide in conjunction with the inner frame rod member 912 even when the inner frame rod member 912 slides upward by applying a force directly to the inner frame rod member 912. That is, the inner frame collar member 912 can move independently. For example, even if one of the pair of upper and lower inner frame collar members 912 is moved upward, the other is not moved and is locked. Still in position.

  Further, the locking device 900 includes a pair of upper and lower front frame set locking members 913 that can slide in the vertical direction along the back surface of the mounting plate 902 at a position above each inner frame collar member 912. The front frame set locking member 913 includes a mounting side piece 914 that is in sliding contact with the back surface of the mounting plate 902 and a support side piece 915 that is in sliding contact with the inner surface of the sliding rod 911. The mounting side piece 914 has a rectangular shape. A locking hole 914a is formed. The locking hole 914a is disposed relative to the insertion hole 902a formed in the mounting plate 902. The sliding rod 911 and the front frame set locking member 913 are always urged upward by a pair of upper and lower coil springs C2. In the present embodiment, the front frame set locking member 913 constitutes the first locking member, and the upper position corresponds to the locking position and the lower position is the non-locking position in the sliding range of the front frame set locking member 913. It corresponds to. The sliding rod 911 is in a tensioned state at an intermediate position (reference position) that can move both upward and downward by the coil springs C1 and C2.

  In the closed state of the front frame set 14, the front frame set collar 14 a provided in the front frame set 14 is inserted into the locking hole 914 a through the communication hole of the inner frame 12 and the insertion hole 902 a of the mounting plate 902. The front frame set locking member 913 is locked to the rear surface of the attachment side piece 914. Thereby, the front frame set 14 is locked to the inner frame 12. The movement of the front frame set locking member 913 when the front frame set 14 is closed will be briefly described. The front frame set locking member 913 is pushed downward by contacting the front frame set collar 14a, and the coil spring. It slides once toward the lower unlocking position against the urging force of C2. Then, it returns to the upper locking position by the urging force of the coil spring C2, and locks the front frame set collar 14a.

  Further, the pair of upper and lower front frame set locking members 913 are configured to slide downward simultaneously at the same time as the sliding rod 911 slides downward. On the other hand, the sliding rod 911 is configured not to slide in conjunction with the front frame set locking member 913 even when the front frame set locking member 913 slides downward due to a direct force applied to the front frame set locking member 913. That is, the front frame set locking member 913 can be moved downward independently. For example, even if one of the pair of upper and lower front frame set locking members 913 is moved downward, the other is not moved. It remains in the locked position.

  When the key inserted into the key hole of the cylinder lock 921 is rotated in the clockwise direction, the sliding rod 911 slides upward from the reference position, and the inner frame rod member 912 moves upward in conjunction with the sliding. To the non-locking position, and the locked state between the inner frame collar member 912 and the metal fitting is released (the inner frame 12 is unlocked). On the other hand, when the key inserted into the key hole of the cylinder lock 921 is rotated counterclockwise, the sliding rod 911 slides downward from the reference position, and the front frame set locking member 913 is interlocked with the sliding. Is displaced to the lower non-locking position, and the locked state between the front frame set locking member 913 and the front frame set collar 14a is released (the front frame set 14 is unlocked).

  Next, a configuration for enhancing the defense performance against unauthorized opening of the front frame set 14 and the inner frame 12 will be described.

  An opening restriction unit 931 as an opening restriction means is attached to the lower part of the base frame 901 with respect to the outer surface of the support plate 903 (the surface on the inner side of the inner frame 12: the right surface in FIG. 23). In this embodiment, the opening restriction unit 931 is arranged between the lower inner frame collar member 912 in the locking position and the lower front frame set locking member 913 in the locking position in the vertical direction. It is provided at the corresponding position.

  As shown in FIG. 24, the opening restriction unit 931 includes a mounting base 932 fixed to the support plate 903 and a locking solenoid 933 fixed to the mounting base 932. The mounting base 932 includes a fixing portion 932a that is screw-fixed in a state of being in surface contact with the outer surface of the support plate 903, and an inner side of the inner frame 12 from the rear edge of the fixing portion 932a (right side in FIGS. 22 and 23). And a unit side guide wall portion 932c extending rearward from the boundary portion between the fixed portion 932a and the pedestal portion 932b. In this embodiment, the mounting base 932 is configured by bending a single metal plate. The mounting base 932 is attached such that the unit-side guide wall portion 932c protrudes rearward from the rear edge portion of the support plate 903 of the base frame 901. In addition, a guide hole 935 (opening) penetrating in the left-right direction is formed in the unit-side guide wall portion 932c (see FIG. 23 and the like).

  As shown in FIG. 22, the support plate 903 of the base frame 901 includes a main body side guide wall portion 941 that protrudes rearward from the rear edge portion and faces the unit side guide wall portion 932c. A guide hole 942 facing the guide hole 935 of the unit side guide wall 932c is formed in the main body side guide wall 941 (see FIG. 23).

  Further, as shown in FIG. 24, the opening restriction unit 931 includes a substantially cylindrical conductive member 951 whose one end is fitted and fixed in the guide hole 935 of the unit side guide wall 932c, and a movable member inserted into the conductive member 951. And a member 955.

  When the opening restriction unit 931 is attached to the base frame 901, the other end of the conducting member 951 is fitted and fixed in the guide hole 942 of the main body side guide wall 941. Further, as shown in FIG. 24B, the conducting member 951 includes a bulging portion 952 that protrudes to the outer peripheral side at the intermediate portion in the longitudinal direction, and in the attached state of the opening restriction unit 931 to the base frame 901. The bulging portion 952 is sandwiched between the unit side guide wall portion 932c and the main body side guide wall portion 941 (see FIG. 23). The presence of the bulging portion 952 prevents the conductive member 951 from dropping from the guide holes 935 and 942 of the guide wall portions 932c and 941. In this example, the conductive member 951 is made of resin.

  As shown in FIG. 24, the movable member 955 includes a columnar movable member main body 956 and an enlarged diameter portion 957 formed on one end side of the movable member main body 956, and from the inner side of the inner frame 12. The conductive member 951 is inserted. Due to the presence of the enlarged diameter portion 957, the movable member 955 is prevented from falling off from the conducting member 951 to the outer side of the inner frame 12. Further, the movable member 955 is configured to be longer than the conducting member 951. When the enlarged diameter portion 957 and the conducting member 951 come into contact with each other, the distal end portion of the movable member 955 is moved from the conducting member 951 to the outer side of the inner frame 12 (see FIG. 23, it protrudes greatly to the left). In this embodiment, the movable member 955 is made of a magnetic material (soft magnetic material).

  As shown in FIG. 24, the locking solenoid 933 biases the solenoid main body 961, the plunger 962 provided so as to be able to move in and out with respect to the solenoid main body 961, and the plunger 962 in a direction protruding from the solenoid main body 961. A coil spring 963 is provided, and the plunger 962 is fixed to the back side of the pedestal portion 932b so that the plunger 962 protrudes to the outer side of the inner frame 12 (left side in FIG. 23). Since the locking solenoid 933 of this example is a pull-type solenoid, when the power supply to the locking solenoid 933 is stopped and the locking solenoid 933 is in a non-excited state, the biasing force of the coil spring 963 causes a plan. The jar 962 is displaced in a direction protruding from the solenoid body 961. On the other hand, when electric power is supplied to the locking solenoid 933 and the locking solenoid 933 is in an excited state, the plunger 962 is displaced in a direction in which it is retracted into the solenoid body 961 against the urging force of the coil spring 963.

  In this embodiment, the movable member 955 is displaced by the locking solenoid 933. In other words, the locking solenoid 933 is disposed at a position where the distal end of the plunger 962 can come into contact with the enlarged diameter portion 957 of the movable member 955. When the locking solenoid 933 is in a non-excited state, the movable member 955 The plunger 962 is pressed and displaced to the left in FIG. 23 until the enlarged diameter portion 957 and the conducting member 951 come into contact with each other. As a result, the distal end portion of the movable member 955 is in a state of protruding greatly from the conducting member 951 to the outside of the inner frame 12.

  On the other hand, when the locking solenoid 933 is energized, the plunger 962 is displaced toward the solenoid body 961 as described above, and the movable member 955, which is a magnetic body, is attracted to the magnetized plunger 962. , To the right of FIG. As a result, the distal end portion of the movable member 955 is housed inside the conducting member 951. The locking solenoid 933 is arranged so that the distance between the plunger 962 and the conducting member 951 when in the excited state is shorter than the length of the movable member 955, whereby the movable member 955 is connected to the conducting member 955. From 951, the inner frame 12 is prevented from falling out.

  As shown in FIG. 22, the sliding rod 911 protrudes rearward from the rear edge portion, and faces the main body side guide wall portion 941 in a state where it is at a reference position (a state where the cylinder lock 921 is not operated). A locking piece 971 is provided. The locking piece 971 is formed with locking holes 972 facing the guide holes 935 and 942 of the unit side guide wall portion 932c and the main body side guide wall portion 941 when the sliding rod 911 is in the reference position.

  When the locking solenoid 933 is energized, the movable member 955 that protrudes to the left in FIG. 23 from the conducting member 951 is inserted into the locking hole 972 of the locking piece 971. Thereby, the displacement of the sliding rod 911 is regulated. Further, when the locking solenoid 933 is brought into a non-excited state, the movable member 955 comes out of the locking hole 972 of the locking piece 971. As a result, the displacement of the sliding rod 911 is allowed.

  By adopting the above configuration, in the state where the power supply is stopped, for example, even if an attempt is made to unlock the front frame set 14 or the inner frame 12 using an illegally obtained key, the sliding rod 911 is moved by the movable member 955. Therefore, the front frame set 14 and the inner frame 12 cannot be unlocked. Therefore, basically the same operational effects as those of the above embodiment are achieved.

  In addition, the plunger 962 and the movable member 955 of the locking solenoid 933 are always in contact with each other, but the two are not fixed. For this reason, when the displacement of the inner frame collar member 912 (or the front frame set locking member 913) is restricted in a state where the power supply is stopped, the stress acting on the movable member 955 reaches the locking solenoid 933. The risk that the locking solenoid 933 is damaged can be suppressed. In particular, in this embodiment, the displacement direction of the movable member 955 (plunger 962) and the displacement direction of the inner frame collar member 912 and the front frame set locking member 913 are orthogonal to each other. Played. Further, for example, when the movable member 955 is damaged, the movable member 955 can be replaced relatively smoothly. That is, compared to the case where the movable member 955 and the plunger 962 are fixed so as not to be removable, resource saving and cost reduction can be achieved, and the movable member 955 and the plunger 962 are fixed so as to be removable. Compared with the case where it is done, since the attachment / detachment work is unnecessary, the manufacturing workability and the maintainability can be improved, and the structure can be simplified because the screws and the like are unnecessary. Further, a commercially available solenoid can be mounted almost as it is, and cost reduction, productivity improvement, and the like can be achieved.

  In addition, when the locking solenoid 933 is energized, the movable solenoid 955 is attracted to the magnetized plunger 962 and comes out of the locking hole 972 of the locking piece 971. In order to displace the movable member 955 when 933 is in an excited state, there is no need to separately provide an urging means such as a spring or a fixing portion for fixing the urging means, and the structure can be simplified. .

  Further, when the opening restriction unit 931 is attached, the opening restriction unit 931 and the base frame are provided by the presence of the conductive member 951 that is fitted and fixed in the guide holes 935 and 942 of the unit side guide wall portion 932c and the main body side guide wall portion 941. Positioning with respect to 901, and in turn, positioning with respect to the engaging hole 972 of the engaging piece 971 of the sliding rod 911 and the movable member 955 can be performed more reliably. Therefore, for example, it is possible to prevent a situation in which the opening restriction unit 931 having a defect such as the mounting position and mounting direction of the locking solenoid 933 being not accurate is attached to the base frame 901 and the above-described effects are not performed well. Can do. Further, the presence of the conducting member 951 can stabilize the attachment state of the opening restriction unit 931 (prevent the rattling of the mounting base 932), and can guide the movable member 955 more reliably.

  Since the mounting base 932, the locking solenoid 933, and the movable member 955 are unitized, the locking solenoid 933 and the movable member 955 are fixed separately, or the locking solenoid 933 and the movable member 955 Are fixed to different members (for example, the locking solenoid 933 is directly fixed to the resin base 38 and the movable member 955 is fixed to the base frame 901). Improvements and improvements in maintainability can be achieved. In addition, since the mounting position can be changed in units of the opening restriction unit 931, even when the position of the locking piece 971 or the like is inevitably changed when changing the model, the opening restriction unit 931 is attached to the locking device. Can be installed.

  In the above-described embodiment, the plunger 962 and the movable member 955 of the locking solenoid 933 are not fixed, but both may be fixed. Even when this configuration is adopted, the displacement of the inner frame collar member 912 and the front frame set locking member 913 is restricted by providing the conductive member 951 (the main body side guide wall portion 941 and the unit side guide wall portion 932c). In this case, the stress acting on the movable member 955 can be received, and the situation that the locking solenoid 933 is damaged due to the stress acting on the locking solenoid 933 can be prevented.

  One of the main body side guide wall portion 941 and the unit side guide wall portion 932c may be omitted. In addition, when the plunger 962 and the movable member 955 of the locking solenoid 933 are fixed, it is possible to omit both, but as described above, from the viewpoint of preventing the locking solenoid 933 from being damaged, It is desirable that at least one is provided. In consideration of attachment of the conductive member 951, it is desirable that both be provided.

  In the above embodiment, the locking solenoid 411, the movable member 421, and the coil spring C3 may be unitized.

  (E) In the embodiment described with reference to FIG. 22 and the like in (d) above, the front frame set locking member 913 and the inner frame collar member 912 are configured to be independently displaceable. Even if the sliding of 911 is restricted, the displacement of the front frame set locking member 913 and the inner frame hook member 912 is restricted when a force is directly applied to the front frame set locking member 913 and the inner frame hook member 912. I can't. Therefore, for example, when a wire rod or the like that has entered the pachinko machine 10 is hooked to the pair of upper and lower inner frame collar members 912 and both inner frame collar members 912 are displaced to the non-locking position, the inner frame 12 May be unlawfully released. For this reason, in order to restrict the unlocking of the inner frame 12 in a state where the power supply is stopped, the inner frame collar member 912 or the inner frame collar member 912 cannot be displaced and cannot be removed (difficult to remove). It is desirable that an opening restricting means such as a locking solenoid 933 can be brought into contact with at least one of the members to be fixed, and the displacement of the inner frame collar member 912 is directly restricted in a state where the power supply is stopped. .

  That is, as shown in FIG. 25, an inner frame hook piece 981 extending upward from the inner frame hook member 912 toward the main body side guide wall portion 941 is provided, and the inner frame hook piece 981 is provided with respect to the inner frame hook piece 981. When the member 912 is in the locking position, the inner frame locking holes 981a facing the guide holes 935 and 942 of the guide wall portions 932c and 941 are formed, and when the locking solenoid 933 is in a non-excited state, the guide holes 935 , 942 and the inner frame locking hole 981a may be inserted into the movable member 955 to restrict the displacement of the inner frame collar member 912. In this way, by adopting a configuration that directly regulates the displacement of the inner frame collar member 912 instead of the sliding collar 911 that is interlocked with the inner frame collar member 912, the inner frame collar member in a state where the power supply is stopped. Even if a force is directly applied to 912, it is impossible to displace the inner frame collar member 912. Therefore, unauthorized opening of the inner frame 12 can be prevented more reliably.

  Further, as shown in the figure, a front frame locking piece 983 extending from the front frame set locking member 913 toward the main body side guide wall portion 941 is provided, and the front frame is fixed to the front frame locking piece 983. When the set locking member 913 is in the locking position, the inner frame locking hole 981a of the inner frame locking piece 981 and the front frame locking holes 983a facing the guide holes 935 and 942 of the guide wall portions 932c and 941 are formed. When the locking solenoid 933 is in a non-excited state, the movable member 955 is inserted into the guide holes 935 and 942, the inner frame locking hole 981a, and the front frame locking hole 983a, and the front frame set locking member 913 You may employ | adopt the structure that a displacement is controlled. In this case, even if a force is directly applied to the front frame set locking member 913 in a state where the power supply is stopped, the front frame set locking member 913 cannot be displaced. Accordingly, unauthorized opening of the front frame set 14 can be prevented more reliably.

  As shown in FIG. 25, when both the inner frame engaging piece 981 and the front frame engaging piece 983 are provided, the inner frame provided on one of the inner frame collar member 912 and the front frame set locking member 913 is provided. The positions of the inner frame locking piece 981 and the front frame locking piece 983 are shifted in the left-right direction so that the other displacement is not hindered by the frame locking piece 981 or the front frame locking piece 983 (internal direction in the left-right direction). The frame locking piece 981 and the front frame locking piece 983 are configured to overlap each other). 25, when the locking solenoid 933 is in a non-excited state, the movable member 955 has an inner frame locking piece in which the direction from the locking position to the non-locking position is the reverse direction. 981 and the front frame locking piece 983 are inserted into inner frame locking holes 981a and front frame locking holes 983a, respectively. For this reason, when the displacement of one side of the inner frame collar member 912 and the front frame set locking member 913 is restricted, a force is applied from the inner frame locking piece 981 or the front frame locking piece 983 provided on the one side. The added movable member 955 is supported by the front frame locking piece 983 or the inner frame locking piece 981 and the conducting member 951 provided on the other side.

  In the configuration shown in FIG. 25, the movable member 955 is inserted into the inner frame locking hole 981a formed in the inner frame locking piece 981 and the front frame locking hole 983a formed in the front frame locking piece 983. As a result, the displacement of the inner frame collar member 912 and the front frame set locking member 913 is restricted. For example, as shown in FIG. 26, the lower side portion of the movable member 955 is substantially above the inner frame collar member 912. A configuration may be adopted in which the displacement of the inner frame collar member 912 and the front frame set locking member 913 is restricted by abutting and the upper side portion being substantially in contact with the lower portion of the front frame set locking member 913. In this case, the same effect can be obtained.

  (F) In the above embodiment, as shown in FIG. 27, the first support piece 402 of the first sliding rod 605 is inserted into the second engagement hole 405 and the first engagement hole 404, and the first You may provide the contact prevention cap 991 (contact prevention means) which covers the insertion part 425 and the nail | claw part 426 of the movable member 421 which protrude outside the inner frame 12 from the support piece part 402. FIG.

  For example, when a cover member that covers the entire locking solenoid 411 (plunger 412, movable member 421, first support piece portion 402, second support piece portion 403, etc.) is provided, the first support piece portion is provided for the cover member. It is necessary to form a slit for allowing sliding of 402 and the second support piece 403. When the slit is configured to be small, there is a high possibility that the sliding of the first support piece portion 402 or the second support piece portion 403 is hindered due to a manufacturing error or the like. In such a case, there is a possibility that an act of causing the wire member or the like to enter the inside of the cover member through the slit and pressing the distal end portion of the movable member 421 may be performed.

  On the other hand, by adopting a configuration in which the first support piece portion 402 is provided with the contact prevention cap 991, the distal end portion of the movable member 421 (the end portion on the outer side of the inner frame 12 of the insertion portion 425 and the claw portion 426) is provided. Can be inaccessible. Therefore, it is possible to more reliably prevent the act of pressing the distal end portion of the movable member 421 and making the first sliding rod 605 and the second sliding rod 635 slidable.

  The contact prevention cap 991 may be formed integrally with the first support piece portion 402 as shown in FIG. 27 (a), or the first support piece portion as shown in FIG. 27 (b). 402 may be configured as a separate body. However, the contact prevention cap 991 is provided so as to be difficult to remove from the first support piece portion 402 (for example, the head of the screw to which the contact prevention cap 991 is fixed is positioned on the surface side facing the second support piece portion 403. And it is more desirable to be provided so that it cannot be removed. In addition to the contact prevention cap 991, a portion of the movable member 421 located on the inner frame 12 inner side (right side in FIG. 27) than the second support piece 403, and the locking solenoid 411 (and the coil spring C3). It is good also as providing the cover member which covers. In this case, the act of pressing the movable member 421 and the plunger 412 to make the first sliding rod 605 and the second sliding rod 635 slidable can be more reliably prevented.

  Incidentally, in correspondence with the configuration shown in FIG. 22 described in (d) above, a contact prevention cap 991 may be provided on the sliding rod 911 (locking piece 971). Further, in response to the configuration shown in FIG. 25 described in (e) above, a contact prevention cap 991 may be provided on the front frame locking piece 983. Moreover, you may comprise the conduction | electrical_connection member 951 shown in FIG.22, FIG.25 etc. like FIG. 28 (a), (b). That is, a blocking portion 993 that covers the enlarged diameter portion 957 of the movable member 955 may be provided for the conducting member 951 when the locking solenoid 933 is in a non-excited state. In this case, it is possible to prevent the act of displacing the movable member 955 by hooking a wire or the like on the enlarged diameter portion 957. When the plunger 962 in a non-excited state is pressed and the plunger 962 is displaced in the retracting direction, the movable member 955 is also displaced in the same direction (for example, the plunger 962 and When the movable member 955 is connected), the locking solenoid 933 is also in a non-excited state with respect to the spring hook portion 962a formed at the distal end portion of the plunger 962 and supporting one end portion of the coil spring 963. In some cases, it may be covered by the blocking portion 993.

  As shown in FIGS. 28A and 28B, a closing portion 993 is integrally formed with a conductive member 951 configured separately from the base frame 901 and the mounting base 932 (see FIGS. 22 and 25). In this case, the closing portion 993 can be formed relatively easily as compared with the case where the closing portion 993 is formed on the base frame 901 or the mounting base 932. In particular, as shown in FIG. 28A, in the case of adopting a configuration in which the enlarged diameter portion 957 of the conducting member 951 is sandwiched between the unit side guide wall portion 932c and the main body side guide wall portion 941, an opening restriction unit 931 is provided. Since it is impossible to remove the conducting member 951 without removing it from the base frame 901, it is possible to prevent a situation in which the conducting member 951 itself is removed. Therefore, the crime prevention performance against unauthorized unlocking can be enhanced while simplifying the configuration.

  (G) Although not particularly mentioned in the above embodiment, as the cylinder lock 700, for example, the cam plate 720 is displaced unless the key inserted into the keyhole is rotated (key operation of the cylinder lock 700). An incapable one may be employed, or one in which the cam plate 720 can be displaced by inserting a key into the keyhole may be employed.

  Although not particularly mentioned in the above embodiment, when the first sliding rod 605 and the second sliding rod 635 are at the reference position, the upper engagement claw 720a and the lower engagement claw 720b of the cam plate 720 are The upper engagement holes 725 and 727 and the lower engagement holes 726 and 728 may be inserted, or may not be inserted. In the case of adopting the former configuration, if no key operation is performed, even if a direct force is applied to the first sliding rod 605 and the second sliding rod 635, the first sliding rod 605 and the second sliding rod 605 Since the sliding rod 635 can be made undisplaceable, the protection performance against unauthorized opening of the front frame set 14 and the inner frame 12 can be enhanced even when power is supplied. Further, when the former configuration is adopted, an electric power supply is provided by providing an opening restriction means that comes into contact with the cam plate 720 and restricts the rotational movement of the cam plate 720 when the electric power supply is stopped. The key operation in the state where is stopped can be made impossible, and the same effect as the above-described embodiment can be obtained.

  On the other hand, when the latter configuration is adopted, for example, a sliding operation portion that protrudes to the outer side of the inner frame 12 is provided at a substantially intermediate position of the first sliding rod 605, and the second sliding rod 635 is opposed to the second sliding rod 635. Thus, an allowable hole for allowing the sliding operation portion to be inserted and displaced downward may be formed. That is, when the latter configuration is adopted, since the sliding of the first sliding rod 605 and the second sliding rod 635 is not restricted by the cam plate 720, the cylinder lock 700 is opened in a state where the inner frame 12 is opened. Even if the key operation is not performed, the first sliding rod 605 can be slid downward by pushing down the sliding operation portion, and the front frame set 14 (back pack unit 203) can be opened. it can.

  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) 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 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.

  (I) 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.

  (J) In the above embodiment, the inner frame 12 is unlocked by inserting a key into the keyhole of the cylinder lock 700 and turning clockwise, and the front frame set by turning counterclockwise. 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.

  (K) The configuration of each collar part such as the inner frame collar parts 637, 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.

  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.

  (L) As shown in FIGS. 3 and 4, in the above embodiment, the locking solenoid 411, the movable member 421, the first support piece 402, and the second are provided on the right side of the inner frame 12 and the front frame set 14. In order to accommodate the support piece 403, an installation hole 441 and an accommodation recess 442 penetrating in the front-rear direction are formed. However, the present invention is not particularly limited to such a configuration. For example, the installation hole 441 formed in the inner frame 12 is configured as a recess recessed forward rather than through the front and rear, and the locking solenoid 411, the movable member 421, The first support piece portion 402 and the second support piece portion 403 may not be contactable.

  Further, for example, by disposing the locking solenoid 411, the movable member 421, the first support piece 402, and the second support piece 403 on the back side of the inner frame 12 (resin base 38), the installation hole 441 and Even if the housing recess 442 is omitted and the front frame set 14 is opened, members such as the locking solenoid 411 may not be contactable.

  When these configurations are employed, the locking solenoid 411 and the movable member 421 can be made inaccessible or difficult to contact by providing the locking solenoid 411 and the movable member 421 on the front surface of the mounting plate 602. The effect of being able to deter fraudulent actions such as making the locking solenoid 411 immersive is more reliably achieved.

  Alternatively, the front frame set 14 may not be opened unless the inner frame 12 is opened. For example, a locking piece portion extending rearward from the first sliding rod 605 (supporting side wall portion 607 of the main body portion 608) is provided, and when the inner frame 12 and the front frame set 14 are closed, the locking piece portion becomes the outer frame. It is good also as contacting and latching on the upper side part of the latching metal fitting provided in 11. In this case, when the inner frame 12 and the front frame set 14 are closed, even if the first sliding rod 605 is slid downward, the locking piece is caught by the locking bracket, and the sliding is restricted. The On the other hand, if the inner frame 12 is opened, the locked state between the locking piece and the locking bracket is released, so that the first sliding rod 605 can be slid downward.

  (M) You may implement as a pachinko machine of a different type from the above-mentioned 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.

[Appendix]
The technical idea that can be grasped from the above embodiment will be described below.

  Generally, in a gaming machine such as a pachinko machine, a locking device is provided so that a person other than the store clerk cannot open the door body without permission. Nevertheless, in the game hall, the door body is unlocked and opened illegally, and a lot of game balls are acquired by illegally operating and replacing the control device provided on the back side of the door body. There have been cases where cheating is performed (see, for example, Patent Document 1).

  However, it is difficult to detect illegal acts such as exchanging illegally, such as exchanging control equipment at night or on business holidays outside business hours, and exchanging control devices. The hall could suffer a lot of damage.

  Such a problem is not limited to pachinko machines but is also a problem inherent in other gaming machines such as slot machines.

  The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a gaming machine capable of enhancing the defense performance against unauthorized opening of the door.

Means 1. A door body supported to be openable and closable with respect to the gaming machine body, and a locking device for locking the door body to the gaming machine body,
The locking device operates a predetermined operation member to displace the locking member from a locking position that restricts opening of the door body to a non-locking position that permits opening of the door body. In a gaming machine that switches from a locked state that locks the body to an unlocked state,
There is provided an opening restricting means that is in a first state that allows opening of the door body when power is supplied and that is in a second state that restricts opening of the door body when power supply is stopped. A gaming machine characterized by that.

  According to the means 1, in addition to the locking device that operates the operation member to lock and unlock the door body, there is provided an opening restriction means that regulates the opening of the door body when the power supply is stopped. . Thereby, when the power supply is stopped, the door cannot be opened regardless of whether or not the unlocking operation of the locking device is performed. For this reason, the possibility that the door body is illegally opened in a state where power supply is stopped, for example, outside business hours such as at night can be prevented. Therefore, a situation in which a game is played in that state without noticing that a fraudulent action inside the gaming machine has been performed such as illegally replacing the control device, and the game hall suffers a great deal of damage. Can be prevented. As a result, the defense performance against unauthorized opening of the door can be enhanced.

  The opening restricting means may be provided in the locking device. In this case, it is possible to reduce the number of parts and save space. In addition, “the state where power is supplied” includes the meaning of “the state where the gaming machine is activated”, and “the state where the power supply is stopped” is referred to as “the state where the gaming machine is not activated”. Including meaning. In addition, when a front door and a rear door are provided on the front side and the rear side of the door body that can be opened and closed at the left and right sides of the door body, at least power is supplied to the front door and the rear door. In a state in which is stopped, the opening may be restricted. Examples of the “operation member” include “cylinder lock that is rotated by inserting a key”.

  Note that “restricting the opening of the door” means that the operation member cannot be unlocked (for example, the key cannot be turned when the operation member is a cylinder lock). The locking member does not interlock with the unlocking operation of the operation member (although the unlocking operation can be performed, the locking device cannot be displaced to the unlocked position even if the unlocking operation is performed, and the door body is unlocked. I can't do it).

Mean 2. The opening restricting means is provided on one of the gaming machine main body or the door body,
A movable member that is displaceable between a first position and a second position, and the movable member is displaced from the second position to the first position based on the supply of electric power. Drive means for displacing the movable member from the first position to the second position based on the supply being stopped,
When unlocking the operation member and moving the door body in the closed state in the opening direction,
In a state where power supply is stopped, the movable member in the second position abuts against the other of the gaming machine main body or the door body, thereby restricting the opening of the door body,
In the state where electric power is supplied, the opening of the door body is permitted without the movable member in the first position coming into contact with the other of the gaming machine main body or the door body. The gaming machine according to means 1 characterized by the above.

  According to the means 2, when the power supply is stopped, the relative movement between the door body and the gaming machine main body is restricted by the opening restriction means. As a result, for example, the locking member can be unlocked by hooking a wire rod or the like that has entered the gaming machine directly onto the locking member and applying force directly, or by illegally obtaining a key or the like and unlocking the operating member. Even if the door body is displaced to the locking position, that is, the door body is unlocked, the door body in the closed state cannot be opened. Therefore, the operation and effect of the means 1 such as enhancing the defense performance against unauthorized opening of the door body can be surely achieved.

  The state where the movable member is in the first position is the first state of the opening restricting means, and the state where the movable member is in the second position is the second state of the opening restricting means. In addition, examples of the movable member include a solenoid plunger, and examples of the driving means include a solenoid body. Further, the movable member may be configured as a separate body from the driving means (the driving unit of the driving means). In this case, it is possible to suppress the possibility that the driving unit is damaged and the movable member cannot be displaced. In addition, by configuring the driving means with a solenoid, it is possible to prevent the configuration from becoming complicated or to suppress the enlargement of the opening restriction means.

Means 3. The opening restricting means includes a first position that allows displacement of the locking member toward the non-locking position and a second position that restricts displacement of the locking member toward the non-locking position. A movable member displaceable between, and a driving means for displacing the movable member,
In a state where electric power is supplied, the driving means displaces the movable member to the first position,
The gaming machine according to claim 1, wherein the driving means displaces the movable member to the second position in a state where power supply is stopped.

  According to the means 3, when the power supply is stopped, the displacement of the locking member toward the non-locking position is restricted. Thereby, since the unlocking of the locking device becomes impossible, the door body in the closed state cannot be opened. Therefore, the operation and effect of the means 1 such as enhancing the defense performance against unauthorized opening of the door body can be surely achieved. Further, according to this means, the locking member is not a member that interlocks by performing a predetermined operation, but the displacement of the locking member itself is regulated. The act of unlocking can be surely prevented. When a plurality of locking members are provided, the displacement of at least one of the plurality of locking members to the non-locking position side is restricted in a state where power supply is stopped. That's fine.

  “The opening restricting means is provided on one of the gaming machine main body or the door body, and a movable member that is displaceable between the first position and the second position, and is supplied with electric power. The movable member is displaced from the second position to the first position based on the power supply, and the movable member is moved from the first position to the second position based on the power supply being stopped. A driving means for displacing, and when the operation member is unlocked (when a force is applied to the unlocking position side with respect to the locking member), in a state where power supply is stopped, When the movable member at position 2 abuts against a predetermined portion of the locking member, displacement of the locking member toward the non-locking position is restricted, and in a state where power is supplied, The movable member and the locking member at position 1 There without contact, the displacement of the non-locking position side of the locking member may be "acceptable. Further, for example, in the state where the power supply is stopped, the locking member can be displaced to the non-locking position without coming into contact with the movable member at the first position or while being in sliding contact. In this state, the locking device contacts the movable member in the second position, so that all the stress acting on the locking device toward the non-locking position is received by the movable member. The displacement toward the locking position may be restricted.

Means 4. A door body (first door body) that can be opened and closed with respect to the gaming machine main body, a front door (second door body) that can be opened and closed with respect to the door body, and the front door can be locked to the door body. And a locking device capable of locking the door body to the gaming machine body,
The locking device is
A first locking member that is displaceable between a locking position that restricts opening of the front door and a non-locking position that permits opening of the front door;
A second locking member displaceable between a locking position for restricting the opening of the door body and a non-locking position for allowing the door body to be opened;
An operation member capable of displacing the first locking member and the second locking member in the locking position to the non-locking position by performing a predetermined operation;
When power is supplied, the operation member is operated to enter a first state that allows the front door and the door body to be opened,
A game characterized by comprising an opening restricting means for restricting the opening of the front door and the door body even when the operation member is operated when power supply is stopped. Machine.

  According to the means 4, the defense performance against unauthorized opening of the door body (first door body) and the front door (second door body) can be enhanced.

Means 5. The opening restricting means includes a first position allowing displacement of the first locking member and the second locking member toward the non-locking position, and the non-locking of the first locking member and the second locking member. A movable member that is displaced between a second position that restricts displacement toward the locking position side, and a drive unit that displaces the movable member,
In a state where electric power is supplied, the driving means displaces the movable member to the first position,
The gaming machine according to claim 4, wherein the driving means displaces the movable member to the second position when the power supply is stopped.

  According to the means 5, the configuration of the means 4 can be realized with certainty. Further, according to this means, the first locking member and the second locking member are not interlocked by performing a predetermined operation, but the displacement of the first and second locking members themselves is restricted. Thus, it is possible to reliably prevent the act of undue displacement of the first and second locking members to unlock the door body (first door body) and the front door (second door body). Furthermore, it can be set as the structure which can control the unauthorized opening of a door body and a front door by one opening control means (movable member), and simplification of a structure can be achieved.

  "The opening restricting means includes a first position that does not contact the first locking member and the second locking member that are displaced from the locking position to the non-locking position, and the locking position. A movable member that is in contact with the first locking member and the second locking member that are displaced from the first to the non-locking position, and is displaced between a second position that restricts the displacement toward the non-locking position. The movable member is displaced from the second position to the first position based on power being supplied, and the movable member is moved from the first position based on power supply being stopped. Driving means for displacing to the second position, the movable member is held at the first position in a state where power is supplied, and the movable member is held in a state where power supply is stopped. The member is held in the second position. It may be ".

The gaming machine according to 5.

  For example, when a large load is applied to the movable member at the second position so as to be at the first position, the movable member may be displaced to the first position side. When the displacement direction of the locking member is aligned with the displacement direction of the locking member, the movable member is pushed by the locking member and displaced toward the first position side by applying a force to the locking member on the unlocking position side. There is a risk that. In this case, even a fraudulent person can open the door or front door by intruding a wire or the like into the gaming machine and applying force directly to the locking member or using an illegally obtained key. There is a risk that.

  In this respect, according to the present means 7, the movable member and the locking member come into contact with each other so as to intersect each other. For this reason, the situation that the movable member in the 2nd position will be in the 1st position by being pushed by the locking member can be prevented. Therefore, the above-described effects such as enhancing the defense performance against unauthorized unlocking are reliably exhibited.

  Instead of “intersect”, “orthogonal or almost orthogonal” may be used. In this case, the above-described effects can be achieved more reliably.

  Means 8. The game according to any one of means 3, 5 and 7, wherein the locking member comprises contact preventing means for covering an end of the movable member at the second position on the second position side. Machine.

  According to the means 8, the contact preventing means can prevent the movable member located at the second position from coming into contact with the distal end portion. Therefore, it is possible to reliably prevent the act of displacing the movable member to the first position by pressing the tip of the movable member. The contact preventing means may be formed integrally with the locking member, or formed separately from the locking member main body and then fixed to the locking member main body (difficult to remove or impossible to remove). It may be.

  A hole is formed in the locking member, and the movable member in the second position is inserted into the hole so that the locking member is displaced toward the non-locking position. In the case of adopting a configuration that is restricted, the contact prevention means may be provided corresponding to the hole portion, and the distal end portion of the movable member at the second position may be provided on the locking member. When adopting a configuration in which the displacement of the locking member to the non-locking position side is regulated by being positioned on the non-locking position side, the protrusion is projected from the locking member to the non-locking side.

The force that the movable member receives from the other of the gaming machine main body or the door body that is not provided with the opening restricting means when the door body is to be opened. In this state, when the locking member in the locking position is displaced to the non-locking position, the force that the movable member receives from the locking member) acts on the driving means, and the driving means is damaged. Such a fear can be suppressed. In particular, when the displacement direction of the movable member that is displaced by the drive of the drive means intersects or is orthogonal to the direction of the force that acts on the movable member when the movable member restricts unauthorized opening of the door body or the front door. The effect is more reliably exhibited. Further, for example, when the movable member is damaged, the movable member can be replaced relatively smoothly. That is, compared to the case where the movable member and the driving means are fixed so as not to be removable, resource saving, cost reduction, etc. can be achieved, and when the movable member and the driving means are fixed so as to be removable. In comparison, since the attaching / detaching work is not required, the manufacturing workability and the maintainability can be improved, and the structure can be simplified because the screws are not required. In addition, a commercially available drive means (for example, a solenoid) can be mounted almost as it is, and cost reduction, productivity improvement, and the like can be achieved.

  “When the driving means is constituted by a pull type solenoid, the movable member is constituted by a magnetic material, and the power supply to the driving means is stopped and the driving means is in a non-excited state, The plunger is displaced in a direction protruding from the solenoid body by a biasing force of a spring provided corresponding to the jar, and the movable member is pressed by the plunger and displaced to the second position. When power is supplied to the driving means and the driving means is in an excited state, the plunger is displaced in a direction to be immersed in the solenoid body against the biasing force of the spring, and the movable member is magnetized. It is good also as "it is attracted by the plunger which was made and is displaced to the said 1st position." In this case, it is possible to configure an opening restricting means that achieves the effect of the means 9 relatively easily. That is, there is no need to separately provide a biasing means such as a spring or a fixing portion for fixing the biasing means in order to displace the movable member to the first position when the driving means is in an excited state. Thus, it is possible to improve the manufacturing workability.

  According to the means 10, for example, when the driving means and the movable member are separately fixed, or when the driving means and the movable member are fixed to separate members (for example, the driving means is a door body). Compared to (directly fixed to the first door body and the movable member being fixed to the base body), it is possible to improve the mounting workability and the maintenance property. Further, since the opening restricting means can change the mounting position on a unit basis, even if it is necessary to change the mounting position of the opening restricting means when changing the model, the opening restricting means for the locking device. Can be installed.
