There has been known one provided with a transmission mechanism for interlocking a plurality of scissors members according to an unlocking operation of the lock. And in the locked state, each gutter member engages with the corresponding engaged portion, so that the gaming machine main body cannot be opened with respect to the fixed frame. On the other hand, when the cylinder lock is unlocked with a dedicated key, the hook members are simultaneously detached from the engaged portions via the transmission mechanism, and the gaming machine main body can be opened (see, for example, Patent Document 1).

  In recent years, gaming halls have been used for illegal activities to acquire a large number of gaming media by illegally unlocking the gaming machine body during operation and illegally operating or exchanging control devices provided on the back side of the gaming machine. Sometimes it is. Such unauthorized unlocking is usually performed by inserting a wire such as a wire from the gap between the gaming machine main body and the fixed frame and hooking the wire to a hook member, a cylinder lock cam plate, a transmission mechanism or the like to move in the unlocking direction. Is done. When an unauthorized unlocking operation is performed on the heel member or the like, the heel member is detached from the engaged portion, and the gaming machine main body can be opened.

  Now, at the normal time, the first sliding rod 607 and the second sliding rod 627 are respectively urged downward or upward by a coil spring C1 as an urging means. More specifically, the first sliding rod 607 is provided with a hook portion 621. The second sliding rod 627 is provided with a hook portion 641. Further, the second sliding rod 627 is formed with a substantially rectangular insertion hole 642 that is long in the vertical direction at a position above the hook portion 641 corresponding to the hook portion 621 of the first sliding rod 607.

  One end of the coil spring C1 is hooked on the hook portion 621 of the first sliding rod 607, and the other end is hooked on the hook portion 641 of the second sliding rod 627 through the insertion hole 642.

  Due to the tensile force of the coil spring C1, the upper edge of the guide hole 615, 616, 617 is normally urged by the guide pins 618, 619, 620 to suppress the downward movement of the first sliding rod 607. Is held in a locked state. On the other hand, the second sliding rod 627 is held in a state where the lower edges of the guide holes 635, 636, 637 are urged by the guide pins 618, 619, 620, and the upward movement is suppressed. When a cylinder lock 700 described later is operated, the first sliding rod 607 is displaced upward or the second sliding rod 627 is displaced downward against the tensile force of the coil spring C1. .

  In the sliding range of the first sliding rod 607, the positions where the upper edge portions of the guide holes 615, 616, 617 abut on the guide pins 618, 619, 620 are the inner flange portions 84, 85. It becomes a position engaged with the parts 609 and 610. That is, this position corresponds to the locking position (reference position) of the first sliding rod 607 (inner rod receiving portions 609, 610). Therefore, the state in which the first sliding rod 607 is in this position corresponds to the locking state of the locking mechanism of the inner frame 12.

  On the other hand, the positions where the lower edge portions of the guide holes 615, 616, and 617 contact the guide pins 618, 619, and 620 are separated from the inner flange receiving portions 609 and 610 (disengagement). It becomes the position. That is, this position corresponds to the unlocking position of the first sliding rod 607. Therefore, the state where the first sliding bar 607 is in this position corresponds to the unlocked state of the locking mechanism of the inner frame 12.

  On the other hand, in the sliding range of the second sliding rod 627, the position where the lower edge portion of the guide hole 635, 636, 637 abuts on the guide pins 618, 619, 620 is the front collar portion 91, 92, 93. It becomes a position engaged with the hook receiving parts 628, 629, and 630. That is, this position corresponds to the locking position (reference position) of the second sliding rod 627 (front rod receiving portions 628, 629, 630). Therefore, the state where the second sliding rod 627 is in this position corresponds to the locking state of the locking mechanism of the front frame 14.

  On the other hand, the positions where the upper edge portions of the guide holes 635, 636, 637 abut on the guide pins 618, 619, 620 are separated from the front collar receiving portions 628, 629, 630 ( The position is disengaged. That is, this position corresponds to the unlocking position of the second sliding rod 627. Therefore, the state where the second sliding rod 627 is in this position corresponds to the unlocked state of the locking mechanism of the front frame 14.

  A cylinder lock 700 serving as a lock member is attached to the wide portion 602a of the attachment plate 602.

  The cylinder lock 700 has a fixing portion 700a fixed to the back surface of the mounting plate 602, and extends through the mounting plate 602 from the fixing portion 700a forward, and has a lock shaft (not shown) therein. A lock main body 700b having a key hole 702 on the front surface side, and a rotation operation of a key connected to the lock shaft on the back surface side of the fixing portion 700a and inserted into the key hole 702 is performed by the first slide rod 607 or the second slide. And a cam plate 720 serving as a transmission member that transmits the moving rod 627.

  Further, a reset pin 703 is provided on the back side of the fixed portion 700a as an operation portion that protrudes rearward and is pressed when the shape (key code) of the keyhole 702 is changed. Correspondingly, a pin hole 901b as an operation hole is formed on the back side of the inner frame 12 (the inner wall 901a of the mounting groove 901) as shown in FIG.

  Here, an example of the key code changing procedure will be described. First, with the inner frame 12 open, a predetermined jig is inserted through the pin hole 901b and the reset pin 703 is pressed. In this state, the current key is inserted into the keyhole 702 and rotated, and then the key is pulled out. Then, with the reset pin 703 pressed, a new key to be set is inserted into the key hole 702, and the key is released after the pressing state of the reset pin 703 is released after rotating the reverse direction of the current key. Pull out. By performing the operation as described above, a key code suitable for a new key to be set can be obtained. As a result, it is possible to unify the keys for each game hall and to periodically change the keys to prevent fraud.

  The cam plate 720 includes an upper engagement claw 720a and a lower engagement claw 720b. These engaging claws 720a and 720b are formed at predetermined intervals in the rotational direction of the cam plate 720.

  Corresponding to the cam plate 720, a bulging portion 607a of the first sliding rod 607 is formed with a pair of upper and lower upper engaging holes 725 and lower engaging holes 726 into which the engaging claws 720a and 720b can enter and exit. Yes. Similarly, a pair of upper and lower upper engagement holes 727 and 728 into which the engagement claws 720a and 720b can enter and exit are formed in the bulging portion 627a of the second sliding rod 627. 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.

  Each of the engagement holes 725 to 728 has a substantially rectangular long hole shape that is long in the vertical direction. In the normal overlapping state of the first sliding rod 607 and the second sliding rod 627, at least the upper engagement holes 725 and 727 and the lower engagement holes 726 and 728 are partially partially formed. It overlaps and it will be in the state by which the engaging claws 720a and 720b were each inserted.

  More specifically, as shown in FIGS. 11 and 13, when the cam plate 720 is at the reference position in a state where the key is not inserted into the key hole 702 of the cylinder lock 700, the tip of the upper engaging claw 720a is The first sliding rod 607 and the second sliding rod 627 are inserted into the upper engagement holes 725 and 727, and the lower engagement claw 720 b has a distal end connected to the first sliding rod 607 and the second sliding rod 607. 627 enters the lower engagement holes 726 and 728.

  Next, the operation of the locking device 600 will be described in detail. First, locking and unlocking of the inner frame 12 will be described in detail. In the locked state of the inner frame 12, the first sliding rod 607 takes the reference position, whereby the inner flange portions 84 and 85 of the outer frame 11 are engaged with the inner rod receiving portions 609 and 610, and the inner frame 12. The opening of is regulated.

  When the inner frame 12 is unlocked, a key is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise as viewed from the front side of the pachinko machine 10 (see FIG. 1). This operation corresponds to the first operation in the present embodiment. As a result, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b contacts the upper edge portion of the lower engagement hole 726 of the first sliding rod 607.

  Thereafter, as the cam plate 720 is further rotated, as shown in FIGS. 20 (a) and 20 (b) and FIGS. 22 (a) and 22 (b), the lower engaging claw 720b is pulled by the coil spring C1. The first sliding rod 607 is pushed upward against this. 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 607 and the second sliding rod 627. At this time, a space for the lower engagement claw 720b to be displaced upward is secured above the lower engagement hole 728 of the second sliding rod 627 through which the lower engagement claw 720b is inserted. In the process of pushing up the moving rod 607, the lower engaging claw 720b does not come into contact with the second sliding rod 627 so that the operation is not hindered.

  When the first sliding rod 607 slides upward, the engagement between the inner flange receiving portions 609 and 610 and the inner flange portions 84 and 85 is released, and the opening of the inner frame 12 is allowed. Further, when the force of the hand operating the key is loosened when the inner frame 12 is opened, the first sliding rod 607 is pulled downward by the tensile force of the coil spring C1, and returns to the reference position. Accordingly, the cam plate 720 and the lock shaft also return to the reference position.

  On the other hand, when locking the inner frame 12 in the open state, the inner frame 12 is closed without using a key, and the inclined portions of the head portions 84d and 85d of the inner collar portions 84 and 85 of the outer frame 11 are formed. When it hits the lower edge of the inner flange receiving portions 609 and 610, an upward external force is applied to the first sliding rod 607, and the first sliding rod 607 slides upward against the tensile force of the coil spring C1. Move. When the head portions 84d and 85d of the inner flange portions 84 and 85 get over the lower edge portions of the inner flange receiving portions 609 and 610, the first sliding rod 607 returns to the original position by the tensile force of the coil spring C1. As a result, the inner collar portions 84 and 85 are engaged with the inner collar receiving portions 609 and 610, and the inner frame 12 is locked.

  Next, locking and unlocking of the front frame 14 will be described in detail. In the locked state of the front frame 14, the second sliding rod 627 takes the reference position so that the front flange portions 91, 92, and 93 of the front frame 14 are engaged with the front rod receiving portions 628, 629, and 630. The opening of the front frame 14 is restricted.

  When unlocking the front frame 14, a key is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise as viewed from the front side of the pachinko machine 10. This operation corresponds to the second operation in the present embodiment. 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 727 of the second sliding rod 627.

  Thereafter, as the cam plate 720 is further rotated, as shown in FIGS. 21 (a), (b) and FIGS. 23 (a), (b), the upper engaging claw 720a is pulled by the coil spring C1. The second sliding rod 627 is pushed downward against this. At the same time, the lower engaging claw 720b is detached from both the lower engaging holes 726 and 728 without acting on the second sliding rod 627 and the first sliding rod 607. At this time, a space for the upper engagement claw 720a to be displaced downward is secured below the upper engagement hole 725 of the first sliding rod 607 through which the upper engagement claw 720a is inserted. In the process of pushing down the moving rod 627, the upper engaging claw 720a does not contact the first sliding rod 607, and the operation is not hindered.

  When the second sliding rod 627 slides downward, the engagement of all the front collar receiving portions 628, 629, 630 and the front collar portions 91, 92, 93 is released, and the opening of the front frame 14 is allowed. The Further, when the force of the hand operating the key is loosened when the front frame 14 is opened, the second sliding rod 627 is pulled upward by the tensile force of the coil spring C1, and returns to the reference position. Accordingly, the cam plate 720 and the lock shaft also return to the reference position.

  On the other hand, when locking the front frame 14 in the open state, the front frame 14 is closed without using a key, and the heads 91c, 92c, 93c of the front flange portions 91, 92, 93 of the front frame 14 are closed. When the slanted portion of the front end collides with the lower edge of the engagement holes 628a, 629a, 630a of the front rod receiving portions 628, 629, 630, an external force is applied to the second sliding rod 627 in the downward direction, and the second sliding rod 627 slides downward against the tensile force of the coil spring C1. When the head portions 91c, 92c, 93c of the front collar portions 91, 92, 93 get over the lower edges of the engagement holes 628a, 629a, 630a of the front collar receiving portions 628, 629, 630, the second sliding collar 627 returns to the original position by the tensile force of the coil spring C1. As a result, the front collar portions 91, 92, 93 are engaged with the front collar receiving portions 628, 629, 630, and the front frame 14 is locked.

  As described above in detail, in the present embodiment, the locking device 600 is disposed in the accommodation space formed between the inner frame 12 and the front frame 14, and between the inner frame 12 and the base frame 601. In the formed internal space, the locking mechanism of the inner frame 12 and the locking mechanism of the front frame 14 are arranged. In addition, the collar portion or the like does not protrude from the back side of the inner frame 12 or the front side of the base frame 601. For this reason, even if it is attempted to perform an illegal act of illegally unlocking the inner frame 12 or the front frame 14, there is no protruding part such as a hook that can hook the wire rod, and it is extremely It becomes difficult. As a result, the defense performance against unauthorized unlocking using a wire or the like can be enhanced.

  In the present embodiment, the extending wall portion 83 is formed so as to cover the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12. In addition, the inner collar portions 84 and 85 provided in front of the same include base portions 84b and 85b provided so as to face the insertion holes 908 and 909 of the inner frame 12, and the outer frames of the base portions 84b and 85b. 11 is provided with folded portions 84e and 85e extending rearward from the inner edge. Further, ribs 908 a and 909 a are formed to protrude rearward around the insertion holes 908 and 909 of the inner frame 12. As a result, it becomes more difficult to perform a fraudulent act such as causing a wire rod or the like to enter from the back side of the inner frame 12 through the insertion holes 908 and 909 and operating the locking mechanism of the inner frame 12 with the wire rod or the like. The performance can be improved.

  In addition, by increasing the defense performance as described above, the configuration of the locking device 600 itself can be made relatively simple.

  In the present embodiment, the shape of the keyhole 702 is determined by pressing the reset pin 703 of the cylinder lock 700 via the pin hole 901b formed on the back side of the inner frame 12 (the back wall 901a of the mounting groove 901). (Key code) can be changed. This eliminates the need to bother to remove the locking device 600 from the inner frame 12 in order to operate the reset pin 703. As a result, while improving the defense performance against unauthorized unlocking, the convenience can be improved at the same time.

  Further, an extension wall portion 83 is formed on the outer frame 11 so as to cover the locking device 600 (the back wall portion 901a of the mounting groove portion 901) from the back side of the inner frame 12. Thereby, while further improving the defense performance with respect to the inner flange portions 84 and 85 and the inner flange receiving portions 609 and 610, even if the pin hole 901b is always open in the back wall portion 901a, the pin hole It is difficult to enter a wire rod or the like via 901b and perform an illegal act on the locking device 600.

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

  (A) The configuration of the locking device 600 is not limited to the above embodiment. For example, in the above-described embodiment, the flange receiving portions such as the inner flange receiving portions 609 and 610 are integrally formed with the first sliding rod 607 and the like. However, the present invention is not limited to this, for example, the inner flange receiving portions 609 and 610. The members corresponding to the front saddle receiving portions 628, 629, and 630 may be individually assembled so as to be relatively displaceable with respect to the base frame 601, and may be moved by one sliding rod.

  (B) The configurations of the inner collar receiving portions 609, 610 and the front collar receiving portions 628, 629, 630 are not limited to the above embodiment. For example, in the above-described embodiment, the inner collar receiving portions 609, 610 and the like are configured to slide and move in the vertical direction. However, the present invention is not limited to this, and for example, members corresponding to the inner collar receiving portions 609, 610, and the like are provided. You may employ | adopt the structure which rotationally displaces to a locking position and an unlocking position.

  Moreover, the number of each collar part such as the inner collar parts 609 and 610 and the corresponding collar parts such as the inner collar parts 84 and 85 is not limited to the number of the above-described embodiments. Alternatively, three or more may be provided corresponding to the locking mechanism of the inner frame 12.

  (C) The configuration of the cylinder lock 700 is not limited to the above embodiment. For example, in the above embodiment, the reset pin 703 for changing the key code is provided on the back side of the fixed portion 700a. However, the reset pin 703 is provided on the front side of the fixed portion 700a and The key code may be changed from the side. Further, although the reset pin 703 is provided on the back side of the fixed portion 700a, it may be configured to have a mechanism that can be operated from the front side of the inner frame 12. In these cases, the pin hole 901b on the back side of the inner frame 12 can be omitted. Also, with such a configuration, there is no need to perform a key code changing operation in an unstable state in which the inner frame 12 is released from the outer frame 11, and the inner frame 12 is closed to the outer frame 11 and is in a stable state. Since work can be performed as it is, workability can be improved.

  Moreover, in the said embodiment, although the pin hole 901b formed in the back wall part 901a of the attachment groove part 901 is a state always open | released, not only this but operation hole parts, such as the pin hole 901b, are normal. May be closed, and may be opened when in use to improve defense performance.

  For example, as shown in FIG. 24, a configuration may be employed in which a lid portion 920 that closes the pin hole 901b is assembled to the rear wall portion 901a of the mounting groove portion 901 so as not to be removable.

  More specifically, locking claws 920a are formed on the front side of the lid portion 920 so as to protrude from the upper and lower portions. Correspondingly, four locking holes 901c are formed in the back wall portion 901a. And the said cover part 920 is assembled | attached by latching the said latching claw 920a to the back wall part 901a front side. In a state where the lid portion 920 is assembled to the back wall portion 901a, the latching claw 920a is located on the front surface side of the back wall portion 901a, so that the unlocking operation cannot be performed from the back side of the inner frame 12. Further, since the mounting groove 901 is closed by the base frame 601 of the locking device 600 on the front side of the inner frame 12, the front side of the inner frame 12 is also engaged unless the locking device 600 is removed. The stop / release operation cannot be performed. That is, the lid 920 is in a state that cannot be removed unless it is destroyed.

  On the other hand, when it becomes necessary to change the key code, a tool such as a flathead screwdriver is inserted between the lid 920 and the back wall 901a, and the lid 920 (locking claw 920a) is inserted. The reset pin 703 of the cylinder lock 700 can be operated through the pin hole 901b by removing the pin hole 901b by breaking it or the like. Even when the lid portion 920 is used by being destroyed or the like, only the used lid portion 920 can be returned to the original state only by replacing it with a new unused lid portion 920.

  Further, as shown in FIG. 25, corresponding to the position of the reset pin 703 of the cylinder lock 700, the back wall portion is provided with a detachable lid portion 903 on a part of the back wall portion 901 a of the mounting groove portion 901. An operation hole for operating the reset pin 703 may be formed in 901a.

  More specifically, a plurality of slits 901d are intermittently provided in the back wall portion 901a in a perforated manner so as to surround a substantially rectangular range. As a result, the portion surrounded by the slit 901d is defined as the lid portion 903. And when changing a key code, the said cover part 903 is cut away from the main-body part of the back wall part 901a by cut | disconnecting the circumference | surroundings of the cover part 903 along slit 901d with tools, such as a cutter. By doing so, an operation hole is formed in the back wall 901a, and the reset pin 703 can be operated through the operation hole.

  Instead of the slit 901d, a thin wall portion may be provided around the entire lid portion 903 so that the rear wall portion 901a can be cut. In this way, since a gap through which a wire rod or the like enters is not formed at normal times, the defense performance can be improved.

  When the lid portion 903 is separated, the trace remains on the back wall portion 901a. Therefore, in the unlikely event that a fraudulent act is performed with the lid 903 opened, the fraudulent act can be detected early by confirming it. Therefore, it is possible not only to prevent fraud directly but also to prevent fraud from the aspect of early detection of fraud.

  Of course, the formation position, size, range, shape, material, assembly structure, etc. of the reset pin 703, the pin hole 901b, the lid portion 920, the lid portion 903, etc. are not limited to the above configuration, and can be changed as appropriate. Is possible.

  Further, the lock member is not limited to the cylinder lock, but may be operated using a key such as an electronic key. In such a case, the appropriate key change is not a physical change such as a change in the shape of the keyhole 702, but is performed by rewriting information by an electric or magnetic method based on the operation of the reset pin 703 or the like.

  (D) In the above embodiment, the locking device 600 is fixed from the front side of the inner frame 12 with screws. For example, a locking claw or the like may be formed on the base frame 601 of the locking device 600, and the locking device 600 may be fixed to the mounting groove 901 by the locking claw or the like. Alternatively, the locking device 600 may be fixed by screws from the back side of the inner frame 12 in a state where the locking device 600 is fitted into the mounting groove 901 from the front side of the inner frame 12.

  (E) In the above embodiment, the base frame 601 constituting the outer shell of the locking device 600 is attached to the mounting plate 602 fixed to the inner frame 12 and the rear edge from the inner edge of the inner plate 12 of the mounting plate 602. The support plate 603 protrudes and a flange portion 604 protrudes outward from the rear edge of the support plate 603 to the outer side of the inner frame 12 and has a substantially U-shaped cross section. However, the shape of the base frame 601 is not limited to this. For example, the flange portion 604 may be omitted and the cross section may be substantially L-shaped.

  (F) In the above-described embodiment, the extended wall portion 83 that covers the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12 is formed on the outer frame 11. Not only this but the extended wall part 83 is good also as a structure which abbreviate | omitted, and it is good also as a structure by which the extended wall part 83 was formed only in the part corresponding to the inner collar parts 84 and 85 or the pin hole 901b.

  (G) You may implement as a pachinko machine of a different type from the above-mentioned embodiment. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball similar thereto may be used.

  Hereinafter, the technical idea that is not described in the claims and that can be grasped from the above embodiment will be described together with the effects thereof.

Means 1. A first door supported to be openable and closable with respect to the support;
A second door body supported on the front side of the first door body so as to be openable and closable with respect to the first door body;
A gaming machine comprising: a locking device for locking the first door to the support and locking the second door to the first door;
The locking device is
In the closed state of the second door body and disposed in the accommodating space formed between the second door body and the first door body,
A base frame member fixed to the first door body;
A locking member fixed to the base frame member and operable with a predetermined key from the front surface of the second door body in the closed state of the second door body;
A first hook receiving portion that is engageable with the first hook portion fixed to the support body is provided so as to be relatively displaceable with respect to the base frame member, and through an insertion hole formed in the first door body. From the locked state in which the first hook part that has entered the housing space engages with the first hook receiving part to restrict the opening of the first door body, the first hook part is the first hook receiving part. A first locking mechanism that switches to an unlocked state that is disengaged from the door and allows the first door body to be opened at least in conjunction with the operation of the locking member according to the first operation by the key;
A second hook receiving portion engageable with a second hook portion fixed to the second door body is provided so as to be relatively displaceable with respect to the base frame member, and the second hook portion is the second hook receiving portion. From the locked state in which the opening of the second door body is restricted by engaging the door, the unlocked state in which the second hook part is disengaged from the second hook receiving part and the second door body is allowed to open. A gaming machine comprising: a second locking mechanism that switches in conjunction with at least the operation of the locking member in response to a second operation by the key.

  According to the said means 1, a locking device is arrange | positioned in the accommodation space formed between a 1st door body and a 2nd door body. Further, when locking the first door body, the first flange portion provided on the support body enters the accommodation space through the insertion hole formed in the first door body and engages with the first flange receiving portion. It has a configuration. That is, it has a configuration in which a collar or the like does not protrude from the back side of the first door body. For this reason, even if a wire rod such as a wire is inserted from the back side of the support body or through the gap between the first door body and the support body, There is no protruding part such as a buttocks that can be hooked, and it is extremely difficult to perform the cheating. As a result, the defense performance against unauthorized unlocking using a wire or the like can be enhanced.

  Note that the “engagement” of the collar part and the collar receiving part refers to a state in which the collar part and the collar receiving part are in contact with each other when the door body is moved in the opening direction. In other words, when the door body is moved in the opening direction, even when the hook portion and the hook receiving portion are in a non-contact state with some play in the locked state of the door body, the hook portion and the hook receiving portion. Are in the “engagement” if they are in contact with each other. Conversely, “disengagement” means a positional relationship in which the hook part and the hook receiving part do not contact when the door body is moved in the opening direction, or a state in which the door body can be opened while being in contact.
