  With the above configuration, the first sliding rod 607 and the second sliding rod 627 are restricted from moving in the front-rear direction by the mounting plate 602 and the flange portion 604, and are moved left and right by the guide pins 618, 619, and 620. It is possible to slide up and down while restricting the movement.

  By the way, at normal times, the first sliding rod 607 and the second sliding rod 627 are urged downward or upward, respectively, by the coil spring C1 as urging means. More specifically, a hook portion 621 is provided on the first sliding rod 607. The second sliding rod 627 is provided with a hook 641. Further, the second sliding rod 627 is formed with a substantially rectangular insertion hole 642 vertically long at a position above the hook part 641 corresponding to the hook part 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 via the insertion hole 642.

  Normally, the upper edges of the guide holes 615, 616, and 617 of the first sliding rod 607 are urged by the guide pins 618, 619, and 620 by the tensile force of the coil spring C1, and the downward movement is suppressed. It is held in the state where it was set. On the other hand, the lower edge of the guide holes 635, 636, and 637 of the second sliding rod 627 is urged by the guide pins 618, 619, and 620, and the second sliding rod 627 is held in a state in which upward movement is suppressed. Then, when a cylinder lock 700 described later is operated, the first sliding rod 607 slides upward or the second sliding rod 627 slides downward against the tensile force of the coil spring C1. .

  In the sliding range of the first sliding rod 607, positions where the upper edges of the guide holes 615, 616, 617 abut on the guide pins 618, 619, 620 are the inner hooks 84, 85. The position is engaged with the portions 609 and 610. That is, this position corresponds to the locked position (reference position) of the first sliding rod 607 (the inner hook receiving portions 609 and 610). Therefore, the state where the first sliding rod 607 is at this position corresponds to the locked state of the locking mechanism of the inner frame 12.

  On the other hand, the position where the lower edges of the guide holes 615, 616, 617 contact the guide pins 618, 619, 620 is such that the inner hooks 84, 85 are disengaged from the inner hook receiving portions 609, 610 (disengagement). Position. That is, this position corresponds to the unlock position of the first sliding rod 607. Therefore, the state where the first sliding rod 607 is in this position corresponds to the unlocking 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 edges of the guide holes 635, 636, 637 abut on the guide pins 618, 619, 620 is determined by the front hooks 91, 92, 93. This is a position where the hook receiving portions 628, 629, and 630 are engaged. That is, this position corresponds to the locked position (reference position) of the second sliding rod 627 (front hook receiving portions 628, 629, 630). Therefore, the state where the second sliding rod 627 is in this position corresponds to the locked state of the locking mechanism of the front frame 14.

  On the other hand, the positions where the upper edges of the guide holes 635, 636, 637 abut against the guide pins 618, 619, 620 are such that the front hooks 91, 92, 93 are separated from the front hook receiving portions 628, 629, 630 ( (Disengagement). That is, this position corresponds to the unlock 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.

  Now, a cylinder lock 700 as a lock member is mounted on the wide portion 602a of the mounting plate 602.

  The cylinder lock 700 has a fixing portion 700a fixed to the back surface of the mounting plate 602, extends from the fixing portion 700a forward through the mounting plate 602, and has a lock shaft (not shown) therein. A lock body 700b having a keyhole 702 on the front side thereof, and a lock shaft connected to the lock shaft on the rear side of the fixing portion 700a, and rotating the key inserted into the keyhole 702 by the first sliding rod 607 or the second slide. A cam plate 720 as a transmission member for transmitting to the moving rod 627 is provided.

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

  Here, an example of a key code changing procedure will be described. First, with the inner frame 12 opened, 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, while pressing the reset pin 703, a new key to be set is inserted into the keyhole 702, the key is turned in the opposite direction to the current key, and the pressed state of the reset pin 703 is released. Pull out. By performing the above operations, a key code that matches the key to be newly set can be obtained. As a result, the keys can be unified for each of the game arcades, and the keys can be changed periodically to prevent fraud.

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

  A pair of upper and lower engaging holes 725 and 726 into which the engaging claws 720a and 720b can enter and exit are formed in the bulging portion 607a of the first sliding rod 607 corresponding to the cam plate 720. I have. Similarly, a pair of upper and lower engaging holes 727 and 728 into which the engaging claws 720a and 720b can enter and exit are formed in the bulging portion 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 engagement 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. When the first sliding rod 607 and the second sliding rod 627 are in a superimposed state in a normal state, at least the upper engaging holes 725 and 727 and the lower engaging holes 726 and 728 partially overlap each other. They are overlapped, and the engagement claws 720a and 720b are inserted into them.

  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 engagement claw 720a is , The first sliding rod 607 and the second sliding rod 627 are inserted into the upper engaging holes 725, 727, and the tips of the lower engaging claws 720b are connected to the first sliding rod 607 and the second sliding rod 607. 627 are inserted into 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 hook portions 84 and 85 of the outer frame 11 are engaged with the inner hook receiving portions 609 and 610, and the inner frame 12 is locked. Is restricted.

  Then, when unlocking the inner frame 12, a key is inserted into the keyhole 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 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 (b) and FIGS. 22 (a) and (b), the lower engaging claw 720b exerts the tensile force of the coil spring C1. To push the first sliding rod 607 upward. At the same time, the upper engaging claw 720a is separated from both upper engaging holes 725 and 727 without affecting the first sliding rod 607 and the second sliding rod 627. At this time, a space is provided above the lower engagement hole 728 of the second sliding rod 627 through which the lower engagement claw 720b is inserted, so that the lower engagement claw 720b is displaced upward. In the process of pushing up the moving rod 607, the lower engagement claw 720b does not come into contact with the second sliding rod 627 so that its operation is not hindered.

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

  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 heads 84d and 85d of the inner hooks 84 and 85 of the outer frame 11 are locked. When hitting the lower edges of the inner hook receiving portions 609 and 610, an external force upward 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 heads 84d, 85d of the inner hook portions 84, 85 get over the lower edges of the inner hook receiving portions 609, 610, the first sliding rod 607 returns to the original position by the tensile force of the coil spring C1. Thus, the inner hook portions 84 and 85 are engaged with the inner hook 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 front hook portions 91, 92, 93 of the front frame 14 are engaged with the front hook receiving portions 628, 629, 630 by setting the second sliding rod 627 to the reference position. The opening of the front frame 14 is restricted.

  When unlocking the front frame 14, a key is inserted into the keyhole 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 engaging claw 720a contacts the lower edge of the upper engaging hole 727 of the second sliding rod 627.

  Thereafter, as the cam plate 720 is further rotated, as shown in FIGS. 21 (a) and 21 (b) and FIGS. 23 (a) and 23 (b), the upper engaging claw 720a exerts the tensile force of the coil spring C1. , The second sliding rod 627 is pushed downward. At the same time, the lower engaging claw 720b is separated from the lower engaging holes 726 and 728 without affecting the second sliding rod 627 and the first sliding rod 607. At this time, a space is provided below the upper engagement hole 725 of the first sliding rod 607 into which the upper engagement claw 720a is inserted, so that the upper engagement claw 720a is displaced downward. During the process of pushing down the moving rod 627, the upper engaging claw 720a does not come into contact with the first sliding rod 607, so that the operation is not hindered.

  When the second sliding rod 627 slides downward, all front hook receiving portions 628, 629, 630 are disengaged from the front hook portions 91, 92, 93, and the front frame 14 is allowed to be opened. You. Further, when the force of the hand operating the key is released when the front frame 14 is released, 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 positions.

  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 hooks 91, 92, 93 of the front frame 14 are locked. Of the front hook receiving portions 628, 629, and 630 hits the lower edges of the engaging holes 628a, 629a, and 630a, a downward external force is applied to the second sliding rod 627, and the second sliding rod 627 slides downward against the tensile force of the coil spring C1. When the heads 91c, 92c, 93c of the front hooks 91, 92, 93 get over the lower edges of the engaging holes 628a, 629a, 630a of the front hook receiving portions 628, 629, 630, the second sliding rod is formed. 627 returns to the original position by the tensile force of the coil spring C1. As a result, the front hook portions 91, 92, and 93 are engaged with the front hook receiving portions 628, 629, and 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. The locking mechanism of the inner frame 12 and the locking mechanism of the front frame 14 are arranged in the formed internal space. In addition, a hook portion or the like does not protrude from the rear 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 portion such as a hook portion capable of hooking a wire, and it is extremely difficult to perform the illegal act. It will be difficult. As a result, the performance of protection against unauthorized unlocking using a wire or the like can be improved.

  In the present embodiment, the extension wall portion 83 is formed so as to cover the entire upper and lower sections corresponding to the locking device 600 from the rear side of the inner frame 12. The inner hooks 84, 85 provided in front thereof have bases 84b, 85b provided so as to face the insertion holes 908, 909 of the inner frame 12, and the outer frames of the bases 84b, 85b. 11 is provided with folded portions 84e and 85e extending rearward from the inner edge. Further, ribs 908a and 909a are formed around the insertion holes 908 and 909 of the inner frame 12 so as to protrude rearward. As a result, it becomes more difficult to perform a fraudulent act such that a wire or the like enters from the rear side of the inner frame 12 through the insertion holes 908 and 909 and operates the locking mechanism of the inner frame 12 with the wire 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 this embodiment, the reset pin 703 of the cylinder lock 700 is pressed through a pin hole 901b formed on the back side of the inner frame 12 (the inner wall 901a of the mounting groove 901) to form the keyhole 702. (Key code) can be changed. Accordingly, it is not necessary to remove the locking device 600 from the inner frame 12 in order to operate the reset pin 703. As a result, it is possible to simultaneously improve the convenience while improving the defense performance against unauthorized unlocking.

  The outer frame 11 is formed with an extending wall 83 so as to cover the locking device 600 (the inner wall 901 a of the mounting groove 901) from the back side of the inner frame 12. With this, the protection performance against the inner hook portions 84 and 85 and the inner hook receiving portions 609 and 610 is further improved, and even if the pin hole 901b is always open in the inner wall portion 901a, the pin hole is not affected. It is difficult to allow the wire rod or the like to enter through the 901b and perform an illegal act on the locking device 600.

  Note that the present invention is not limited to the content described in the above embodiment, and may be implemented as follows, for example.

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

  (B) The configuration of the inner hook receiving portions 609, 610 and the front hook receiving portions 628, 629, 630 is not limited to the above embodiment. For example, in the above-described embodiment, the inner hook receiving portions 609, 610 and the like are configured to be slidably displaced in the vertical direction. However, the present invention is not limited to this. For example, members corresponding to the inner hook receiving portions 609, 610 and the like may be used. It is also possible to adopt a configuration in which the rotation position is shifted between the locking position and the unlocking position.

  In addition, the number of each hook receiving portion such as the inner hook receiving portions 609 and 610 and the number of each hook portion such as the inner hooking portions 84 and 85 corresponding thereto are not limited to the number in the above-described embodiment. Or a configuration having three or more 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-described embodiment, the reset pin 703 for changing the key code is provided on the back side of the fixed part 700a, but the reset pin 703 is provided on the front side of the fixed part 700a, The key code may be changed from the side. Although the reset pin 703 is provided on the rear side of the fixing portion 700a, a configuration may be employed in which a mechanism that enables the reset pin 703 to be operated from the front side of the inner frame 12 is provided. In these cases, the pin hole 901b on the back side of the inner frame 12 can be omitted. Further, with such a configuration, it is not necessary to perform a key code changing operation in an unstable state in which the inner frame 12 is opened from the outer frame 11, and the inner frame 12 is closed to the outer frame 11 to maintain a stable state. Since the work can be performed as it is, the workability can be improved.

  Further, in the above-described embodiment, the pin hole 901b formed in the inner wall portion 901a of the mounting groove portion 901 is always open. However, the present invention is not limited to this, and the operation holes such as the pin hole 901b are normally open. May be closed and opened when used to enhance the defense performance.

  For example, as shown in FIG. 24, a configuration in which a lid 920 that closes the pin hole 901b is non-removably assembled to the inner wall 901a of the mounting groove 901 may be adopted.

  More specifically, locking claws 920 a are formed on the front side of the lid portion 920 at two upper and lower portions, respectively. Correspondingly, four locking holes 901c are formed in the back wall portion 901a. Then, the lid 920 is assembled by locking the locking claw 920a on the front side of the back wall portion 901a. When the lid 920 is attached to the back wall 901a, the locking claw 920a is located on the front side of the back wall 901a, so that the locking release operation cannot be performed from the back side of the inner frame 12. In addition, 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 locking device 600 is also engaged from the front side of the inner frame 12 unless the locking device 600 is removed. The stop release operation cannot be performed. That is, the lid 920 cannot be removed unless it is destroyed.

  On the other hand, in a situation where the key code has to be changed, 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. By detaching the pin hole 901b by breaking it or the like and opening the pin hole 901b, the reset pin 703 of the cylinder lock 700 can be operated through the pin hole 901b. Even when the lid 920 is used after being destroyed, it can be returned to the original state only by replacing the used lid 920 with a new unused lid 920.

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

  More specifically, a plurality of slits 901d are intermittently provided in the back wall portion 901a in a perforated shape so as to surround a substantially rectangular range. Thus, a portion surrounded by the slit 901d is defined as the lid 903. When the key code is changed, the periphery of the lid 903 is cut along the slit 901d with a tool such as a cutter to separate the lid 903 from the main body of the back wall 901a. By doing so, an operation hole is formed in the back wall portion 901a, and the reset pin 703 can be operated through the operation hole.

  In place of the slit 901d, a thin portion may be provided around the entire periphery of the lid portion 903 so that the thin portion can be cut from the back wall portion 901a. By doing so, normally, no gap is formed for the wire or the like to enter, so that the defense performance can be enhanced.

  When the lid 903 is cut off, the trace remains on the inner wall 901a. Therefore, in the unlikely event that an illegal act is performed by opening the lid 903, the illegal act can be detected early by confirming that. Therefore, it is possible to prevent fraudulent acts not only from the direct prevention of fraudulent acts, but also from the aspect that fraudulent acts can be detected early.

  Of course, the formation position, size, range, shape, material, assembling structure, and the like of the reset pin 703, the pin hole 901b, the cover 920, the cover 903, etc. are not limited to the above-described configuration, and may be appropriately changed. It is possible.

  The lock member is not limited to a cylinder lock, and may be operated using a key such as an electronic key. In such a case, the change of the matching key 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. However, the present invention is not limited to this. For example, a locking claw or the like may be formed on the base frame 601 of the locking device 600, and the locking device 600 may be fixed to the mounting groove 901 by the locking claw or the like. Further, the locking device 600 may be fixed to the mounting groove 901 from the front side of the inner frame 12 with screws from the rear 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 mounted rearward from the mounting plate 602 fixed to the inner frame 12 and the inner edge of the mounting plate 602 on the inner side of the inner frame 12. It comprises a protruding support plate 603 and a flange portion 604 protruding from the rear edge of the support plate 603 to the outside 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 configuration may be such that the flange portion 604 is omitted and the cross section is substantially L-shaped.

  (F) In the embodiment described above, the outer frame 11 is formed with the extension wall portion 83 that covers the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12. The configuration is not limited thereto, and the extension wall portion 83 may be omitted, or the extension wall portion 83 may be formed only in the portion corresponding to the inner hook portions 84 and 85 and the pin hole 901b.

  (G) The present invention may be implemented as a pachinko machine of a different type from the above embodiment. In addition to the pachinko machine, the present invention may be implemented as an arrangement ball machine or a similar game machine such as a sparrow ball.

  Hereinafter, technical ideas that are not described in the claims and that can be grasped from the above-described embodiments will be described together with their effects.

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

  According to the above means 1, the locking device is disposed in the accommodation space formed between the first door body and the second door body. Further, when the first door is locked, the first hook provided on the support enters the housing space through the insertion hole formed in the first door and engages with the first hook receiver. It has a configuration. That is, the hook portion and the like do not protrude from the back side of the first door body. For this reason, even if a wire such as a wire is inserted from the back side of the support or from the gap between the first door and the support, an unauthorized act of illegally unlocking the first door is attempted. Since there is no protruding portion such as a hook portion that can be hooked, it is extremely difficult to perform the illegal act.
