Description

  The present invention relates to a gaming machine such as a pachinko machine.

  In general, in gaming machines such as pachinko machines, a gaming machine main body (inner frame) is provided to be openable and closable with respect to a support (outer frame) from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the store clerk cannot open the gaming machine body without permission. As such a locking device, a cylinder lock operated using a dedicated key, a plurality of hook members provided so as to be able to be engaged with and disengaged from a plurality of engaged members provided on a support, and a cylinder by a key 2. Description of the Related Art There is a known one having a sliding hook that interlocks a plurality of hook members in accordance with an unlocking operation of the lock. And in the locked state, each gutter member engages with a corresponding engaged member, so that the gaming machine main body cannot be opened with respect to the support. On the other hand, when the cylinder lock is unlocked with a dedicated key, the hook members are simultaneously detached from the engaged members via the sliding hooks, and the gaming machine main body can be opened (see, for example, Patent Document 1).

  In addition, the locking device is generally configured to perform locking without using a dedicated key when locking the gaming machine body from the open state to the closed state. For example, the tip of the saddle member tapers in a substantially triangular shape, and when the gaming machine main body is closed, first, the inclined portion of the saddle member comes into contact with the engaged member. Accordingly, by further closing the gaming machine main body, the saddle member is displaced in the unlocking direction against the biasing force of the biasing member such as a coil spring. When the eaves member gets over the engaged member, the eaves member returns to the original position by the urging force of the urging member and is engaged with the engaged member. This completes the locking of the gaming machine body.

JP 2001-120817 A

  In the prior art, generally, only when the unlocking operation with the key is continued (for example, when the cylinder lock is rotated in a predetermined direction), the eaves member can be maintained on the unlocking side. That is, when the hand is released from the key, the hook member returns to the locking side. Therefore, when performing the operation of opening the gaming machine main body, the operator performs the operation of unlocking the cylinder lock or the like with the key with one hand and pulling the gaming machine main body forward with the other hand. Is required.

  However, in recent years, the number of various devices such as control devices attached to the gaming machine main body has been increasing, so that the gaming machine main body is increasing in weight.

  In addition, the mounting plate 602 is provided with restriction projections 602c that restrict the movement of the second sliding rod 625 to the outer side of the inner frame 12 at two places in the vertical direction. The regulation protrusion 602c has a function as a guide portion for improving the stability of the sliding operation of the second sliding rod 625 as well as a function for improving the stability of the mounting state of the second sliding rod 625. As a result, the second sliding rod 625 is allowed to slide in the vertical direction in a state where movement in the left-right direction is restricted by the restriction protrusion 602c while allowing slight displacement in the front-rear direction. .

  During normal operation (when a restriction is released by a lock member 660 described later), the second sliding rod 625 is urged upward by a coil spring C2 as an urging member. More specifically, one end of the coil spring C <b> 2 is hooked on a hook portion 625 b provided on the second sliding rod 625, and the other end is hooked on a hook portion 626 provided on the mounting plate 602.

  When the second sliding rod 625 is pulled up to the upper unlocking position (second switching position) by the tensile force (biasing force) of the coil spring C2, it is connected to the second sliding rod 625. The front end portions of the inner flange members 623 and 624 are lifted upward, and the shaft pins 631 and 632 are in contact with the upper end edge portions of the guide holes 633 and 634 (see FIG. 25). In other words, the inner flange members 623 and 624 are inclined such that the front side is up and the rear side is down.

  Then, the second sliding rod 625 is pulled downward against the tensile force of the coil spring C2, and the second sliding rod 625 is held at the lower locking position (first switching position) by the lock member 660. In this state, the shaft pins 631 and 632 are in contact with the lower edge of the guide holes 633 and 634 (see FIG. 24). That is, the inner flange members 623 and 624 are in a substantially horizontal state.

  Accordingly, the position where the shaft pins 631 and 632 abut on the upper edge of the guide holes 633 and 634 in the rotation range of the inner flange members 623 and 624 is separated from the metal fittings 83 and 84. Possible unlocking positions. On the other hand, the positions where the shaft pins 631 and 632 abut against the lower edge portions of the guide holes 633 and 634 are the locking positions where the inner flange members 623 and 624 can engage with the receiving fittings 83 and 84.

  Here, the structure of the metal fittings 83 and 84 will be described in detail. The metal fittings 83 and 84 are fixed to the inside of the right side frame constituting portion 11d of the outer frame 11 with screws or the like, and the inner edge of the outer frame 11 from the rear edge portions of the right wall portions 83a and 84a. And rear wall portions 83b and 84b extending to the side, and left wall portions 83c and 84c extending forward from the inner side edge of the outer frame 11 of the rear wall portions 83b and 84b. It is formed in a substantially U-shaped cross section that is concave toward the top.

  Further, rod-like engaged portions 83d and 84d with which the inner flange members 623 and 624 engage are bridged between the right wall portions 83a and 84a and the left wall portions 83c and 84c. When the inner flange members 623 and 624 are engaged with the engaged portions 83d and 84d, the inner flange members 623 and 624 are surrounded by the walls 83a to 83c and 84a to 84c. Become. Thereby, since it becomes difficult to hook a wire etc. with respect to the inner collar members 623 and 624 engaged with the receiving metal fittings 83 and 84, the defense performance against unauthorized unlocking can be improved.

  Now, the bulging portion 603a of the support plate 603 is formed with an extending wall portion 603b extending rearward from the rear edge portion. The extension wall portion 603b is provided with a lock member 660 as a restricting member. As described above, the lock member 660 has a function of holding the second sliding rod 625 in the lower locking position against the tensile force of the coil spring C2, and also has a function of preventing unauthorized unlocking. ing. For example, when the inner frame 12 is closed, an external force in the unlocking direction is applied by hooking a wire or the like illegally to the second sliding rod 625 or the inner rod members 623 and 624 without using the key K. In this case, the sliding displacement of the second sliding rod 625 can be restricted, and consequently the inner collar members 623 and 624 can be maintained in the locked position.

  The lock member 660 includes a vertically long and substantially flat main body piece 660a. The main body piece 660a is formed with a shaft hole 660b at a lower portion thereof and a guide hole 660c at a substantially central portion thereof. The guide hole 660c is formed in a substantially arc shape with the shaft hole 660b as the center. The shaft pins 663 and 664 inserted into the shaft hole 660 b and the guide hole 660 c from the outer side of the inner frame 12 are fixed to the extending wall portion 603 b of the support plate 603. As a result, the lock member 660 is pivotally supported so as to be rotatable and displaceable about the shaft hole 660b (shaft pin 663) along a plane along the front-rear direction and the vertical direction.

  The upper end portion of the main body piece portion 660a is provided with a restriction piece portion 660d that protrudes toward the outer side of the inner frame 12, and the front end portion of the restriction piece portion 660d has an abutting portion 660e that is bent upward. Is provided. The restricting piece 660d functions to restrict the sliding displacement of the second sliding rod 625.

  One end of a coil spring C3 as a second urging member is hooked on the restricting piece portion 660d, and the other end is hooked on a hook portion 665 provided on the extending wall portion 603b. As a result, the upper portion of the lock member 660 is pulled upward and forward, and is urged forward.

  At the time of regulating the sliding displacement of the second sliding rod 625, the lock member 660 is in a state where the rear edge portion of the guide hole 660c is in contact with the shaft pin 664, and the main body piece portion 660a is along the vertical direction. The reference posture (regulation posture) is taken (see FIG. 24).

  In contrast, when the restriction is released, the lock member 660 is displaced against the tensile force (biasing force) of the coil spring C3, and the front edge portion of the guide hole 660c is in contact with the shaft pin 664. The posture of the main body piece 660a is inclined (see FIG. 25).

  That is, in the rotation range of the lock member 660, the position where the shaft pin 664 abuts on the rear edge of the guide hole 660c is the restriction position for restricting the sliding displacement of the second sliding rod 625. On the other hand, the position where the shaft pin 664 contacts the front edge of the guide hole 660c is the restriction release position for releasing the restriction.

  Corresponding to the restriction piece portion 660d, an engagement protrusion 625d extending rearward from the rear edge portion is formed on the bulging portion 625a of the second sliding rod 625. And then. When the restricting piece 660d is engaged with the upper end of the engaging protrusion 625d, the upward displacement of the second sliding rod 625 is restricted.

  In addition, an engaging portion 660f extending from the front edge portion is formed at a substantially central portion of the main body piece portion 660a. The engaging part 660f functions as an action part on which a cam plate 720 of a cylinder lock 700 described later acts. The engagement portion 660f is formed with a step difference from the main body piece portion 660a at the base portion in consideration of the thickness of the second sliding rod 625. The front edge portion of the engaging portion 660f is inclined with respect to the upper edge portion and the lower edge portion, and has a tapered shape from the lower edge portion side to the upper edge portion side. The cam plate 720 is engaged with the front edge portion.

  A cylinder lock 700 as a lock member is attached to the wide portion 602a of the attachment plate 602, and the front side thereof is exposed to the front side of the front frame set 14.

  As shown in FIG. 20, the cylinder lock 700 includes a cylinder body 701 having a substantially cylindrical shape, a lock shaft 703 provided inside the cylinder body 701 and having a key hole 702 inside, and an outer periphery of the cylinder body 701. And an outer cylinder 704 provided.

  In the cylinder lock 700, the flange portion 705 is fixed to the back side of the mounting plate 602 with screws 719 in a state where the cylinder body 701 is inserted into the mounting hole 602d of the mounting plate 602.

  The cylinder body 701 is formed with a total of 16 through-holes 706, each of which is vertically connected to the inside and outside of the cylinder body 701. Correspondingly, 16 through holes 708 communicating with the respective through holes 706 are also formed in the lock shaft 703. The key hole 702 side of the through hole 708 is formed with a smaller diameter than other parts so that a receiving member such as a pin 714 described later does not fall into the key hole 702.

  A spring 709 is accommodated in each through hole 706. One end of the spring 709 is in contact with the outer cylinder 704, and a pedestal 711 is connected to the other end. Each through hole 708 accommodates a plurality of spacers 712, 713 and pins 714 so as to be supported by the pedestal 711. The pins 714, the spacers 712 and 713, and the pedestal 711 can move up and down in the through holes 706 and 708 by the expansion and contraction of the spring 709. Among these, the pin 714 can be projected and retracted in the key hole 702 through a small diameter portion of the through hole 708 on the key hole 702 side.

  With the above configuration, when the key K is inserted into the keyhole 702, the pins 714 and the like move up and down along the concave and convex shapes on both sides of the key K. When the key K is completely inserted, each pin 714 enters the key K groove as shown in FIG. 21, and the base end surface of the pin 714 or one end surface of the spacer 712 or 713 And the outer peripheral surface of the lock shaft 703 are flush with each other. As a result, when the key K is completely inserted, the lock shaft 703 can be rotated as the key K is rotated. That is, the cylinder lock 700 has an internal structure in which the lock shaft 703 cannot be rotated unless at least the key K is inserted into the key hole 702.

  In addition, a cam plate 720 that transmits the rotation operation of the key K inserted into the key hole 702 to the first sliding rod 609 and the lock member 660 is fixed to the rear end portion of the lock shaft 703.

  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. In the present embodiment, the length of the lower engagement claw 720b is set slightly shorter than the length of the upper engagement claw 720a (see FIG. 16).

  Corresponding to the cam plate 720, the bulging portion 610a of the first sliding rod 609 has an upper engagement recess 725 in which the upper engagement claw 720a can engage and a lower hole in which the lower engagement claw 720b can enter and exit. 726 is formed. Further, the bulging portion 603a of the support plate 603 and the bulging portion 625a of the second sliding rod 625 each have a vertically long through hole 731 corresponding to at least the formation range of the upper engagement recess 725 to the lower hole 726. , 732 are formed. The lower hole 726 and the through-holes 731 and 732 are formed so that both the engaging claws 720a and 720b are supported by the support plate 603 and the second sliding rod when the cam plate 720 operates or the second sliding rod 625 slides. This is to prevent interference with 625.

  When the bulging portion 610a of the first sliding rod 609 and the bulging portion 625 of the second sliding rod 625 are overlapped, the through hole 732 of the second sliding rod 625 and the first sliding rod 625 The upper engagement recess 725 and the lower hole 726 are in communication with each other.

  With the above configuration, when the lock shaft 703 and the cam plate 720 are in the reference position when the key K is not inserted into the key hole 702 of the cylinder lock 700, the tip of the upper engagement claw 720a is The second engagement rod 720 is inserted into the upper engagement recess 725 through the through hole 732 of the first slide rod 625, while the tip of the lower engagement claw 720 b is inserted into the lower hole 726 of the first slide rod 609. Is in a state where it cannot be inserted.

  As described above, the cylinder lock 700 according to this embodiment is in a state where the lock shaft 703 and the cam plate 720 cannot be rotated (locked state) when the key K is not inserted into the key hole 702. Therefore, when the cam plate 720 is in the reference position, the sliding of the first sliding rod 609 is restricted by the upper engaging claw 720a with respect to the first sliding rod 609. For example, when an external force in the unlocking direction is applied to the first sliding rod 609 by illegally hooking a wire or the like on the first sliding rod 609 in the locking position without using the key K The upper engaging claw 720a is caught by the edge of the upper engaging recess 725 of the first sliding rod 609, and the sliding displacement of the first sliding rod 609 in the unlocking direction causes the upper engaging recess 725 or the like to move. It is substantially regulated except for play length.

  Further, a cover member 740 is attached and fixed to the locking device 600 so as to cover the back side of the cylinder lock 700. The cover member 740 covers the cam plate 720, the bulging portion 610a of the first sliding rod 609, the bulging portion 625 of the second sliding rod 625, the lock member 660, and the like.

  The cover member 740 includes an attachment base 740a that is attached and fixed to the rear surface of the attachment plate 602 by a fixing means such as a screw, and a protection portion 740b that covers the bulging portion 603a and the extending wall portion 603b of the support plate 603. . In the present embodiment, the cover member 740 is made of a hard and transparent resin material (for example, polycarbonate).

  The attachment base portion 740a is screwed at both upper and lower ends so as to cover the flange portion 705 and the cam plate 720 of the cylinder lock 700 in the attached state.

  The protection part 740b is formed in a substantially box shape opened forward, and is disposed so that the extending wall part 603b of the support plate 603 is inserted therein. As a result, substantially the entire vertical direction of the bulging portion 603a of the support plate 603 is covered (see FIG. 7).

  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 second sliding rod 625 takes the locked position, so that the head portions 623b and 624b of the inner rod members 623 and 624 are engaged with the engaged portions 83d and 84d of the metal fittings 83 and 84, respectively. The opening of the inner frame 12 is restricted (see FIG. 24).

  In a state where the inner frame 12 is locked, the restriction piece 660d of the lock member 660 is located immediately above the engaging protrusion 625d of the second sliding rod 625, and the second sliding rod 625 is slid upward. It is regulated.

  Then, when unlocking the inner frame 12, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise as viewed from the front side of the pachinko machine 10. This operation corresponds to a specific operation in the present embodiment. Thereby, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b contacts the front edge portion (inclined portion) of the engagement portion 660f of the lock member 660.

  Thereafter, as the cam plate 720 is further rotated, the lower engagement claw 720b pushes the engagement portion 660f of the lock member 660 upward. As a result, the lock member 660 receives a backward force and rotates backward against the tensile force of the coil spring C3.

  When the restriction piece 660d of the lock member 660 is disengaged from the engagement protrusion 625d of the second sliding rod 625, the second sliding rod 625 is moved upward by the tensile force of the coil member C2. Be raised.

  When the second sliding rod 625 slides upward, the contact portion 660e at the front end of the regulating piece portion 660d is urged to the rear end edge of the engaging projection 625d of the second sliding rod 625, and the lock member 660 Does not return to the restricted position. That is, the rear end edge of the engaging protrusion 625d corresponds to a specific portion of the connecting member in the present embodiment.

  As the second sliding rod 625 slides upward, the inner flange members 623 and 624 rotate, and the head portions 623b and 624b are disengaged from the engaged portions 83d and 84d of the receiving fittings 83 and 84. Go. At the same time, the action portions 623c and 624c push the engaged portions 83d and 84d of the receiving fittings 83 and 84, respectively.

  Then, the engaged portions 83d and 84d of the receiving fittings 83 and 84 come out of the engaging recesses 623a and 624a of the inner flange members 623 and 624, and the inner flange members 623 and 624 and the receiving fittings 83 and 84 are in the detached state. (See FIGS. 22 and 25).

  When the action portions 623c and 624c of the inner flange members 623 and 624 push the engaged portions 83d and 84d of the receiving fittings 83 and 84, the inner frame 12 is pushed forward, and the inner frame 12 is automatically released. The

  Once the inner frame 12 is unlocked, the second sliding rod 625 and the inner rod members 623 and 624 remain held at the unlocked position by the tensile force of the coil spring C2.

  When the inner frame 12 is locked, locking is performed without using the key K while the second sliding rod 625 and the inner rod members 623 and 624 are held in the unlocked position. More specifically, when the inner frame 12 in the open state is closed, the action portions 623c and 624c of the inner flange members 623 and 624 first come into contact with the engaged portions 83d and 84d of the receiving fittings 83 and 84. Further, when the inner frame 12 is closed, the inner flange members 623 and 624 rotate forward against the tensile force of the coil spring C2, and the second sliding rod 625 slides downward.

  The heads 623b and 624b of the inner flange members 623 and 624 wrap around to the back side of the engaged portions 83d and 84d of the receiving brackets 83 and 84, and the engaged portions 83d and 84d of the receiving brackets 83 and 84 are The inner flange members 623 and 624 return to the locked position so as to enter the engaging recesses 623a and 624a of the flange members 623 and 624. In this way, the head portions 623b and 624b of the inner flange members 623 and 624 are engaged with the engaged portions 83d and 84d of the metal fittings 83 and 84, respectively.

  At the same time, when the upper end portion of the engagement protrusion 625d of the second sliding rod 625 is pulled down to the position of the restriction piece 660d of the lock member 660, the restriction piece portion that has held the lock member 660 in the restriction release position so far. Since the engagement between the contact portion 660e at the front end of 660d and the rear end edge of the engagement protrusion 625d of the second sliding rod 625 is disengaged, the lock member 660 returns to the original restricted position by the tensile force of the coil spring C3.

  Then, the restricting piece 660d of the lock member 660 is positioned immediately above the engaging protrusion 625d of the second sliding rod 625, and the upward sliding of the second sliding rod 625 is regulated. As a result, the opening of the inner frame 12 is restricted, and locking is completed.

  Next, 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 sliding bar 609 takes the locked position, so that the brackets 91, 92, 93 (engaged portions 91c, 92c, 93c), the heads 616c, 617c, and 618c of the front flange portions 616, 617, and 618 are engaged, and the opening of the front frame set 14 is restricted (see FIG. 24).

  When unlocking the front frame set 14, the key K inserted into the key hole 702 of the cylinder lock 700 is inserted and rotated counterclockwise as viewed from the front side of the pachinko machine 10. As a result, the cam plate 720 rotates in the same direction so that the upper engagement claw 720a contacts the lower edge of the upper engagement recess 725 of the first sliding rod 609 and is pushed down by the upper engagement claw 720a. In this way, the first sliding rod 609 slides downward (see FIGS. 23 and 26).

  When the first sliding rod 609 slides downward against the tensile force of the coil spring C1, the engagement between the front flange portions 616, 617, and 618 and the metal fittings 91, 92, and 93 is released, and the front frame Opening of the set 14 is allowed. When the front frame set 14 is opened, when the force of the hand operating the key K is loosened, the first sliding rod 609 is pulled upward by the tensile force of the coil spring C1, and returns to the locking position. .

  On the other hand, the front frame set 14 can be locked without using the key K when the front frame set 14 is locked. More specifically, when the front frame set 14 in the open state is closed, the inclined portions of the head portions 616c, 617c, and 618c of the front flange portions 616, 617, and 618 are engaged portions of the receiving brackets 91, 92, and 93. 91c, 92c, 93c is in contact with the lower side. Further, when the front frame set 14 is closed, the front flange portions 616, 617, and 618 are pushed downward, and once slide against the tensile force of the coil spring C1. Thereafter, when the head portions 616c, 617c, 618c of the front flange portions 616, 617, 618 exceed the engaged portions 91c, 92c, 93c, the front flange portions 616, 617, 618 are restored to the original by the tensile force of the coil spring C1. It returns to the position and is engaged with the engaged portions 91c, 92c, 93c. Thereby, the opening of the front frame set 14 is restricted, and locking is completed.

  As described in detail above, when the inner frame 12 is unlocked by operating the cylinder lock 700, the inner frame 12 is automatically pushed forward and released. Thereby, even when the weight of the inner frame 12 is relatively heavy, a force is applied in the direction in which the inner frame 12 opens, so that the inner frame 12 can be opened relatively easily. As a result, it is not necessary to perform a troublesome operation such as pulling forward while supporting the inner frame 12 with the other hand while operating the cylinder lock 700 with one hand, and the convenience is improved.

  Further, since the coil spring C2 is configured to urge the inner flange members 623 and 624 via the second sliding rod 625, a plurality of coil springs are provided corresponding to the inner flange members 623 and 624, respectively. There is no need, and an increase in the number of parts can be suppressed.

  The action portions 623c and 624c of the inner flange members 623 and 624 that act on the engaged portions 83d and 84d of the receiving metal fittings 83 and 84 when the inner frame 12 is opened are engaged portions 83d even when the inner frame 12 is closed. , 84d, the inner frame 12 is automatically locked when the inner frame 12 is closed. As a result, when the inner frame 12 is locked, it is not necessary to perform a locking operation with the key K, and convenience is improved.

  Further, in the locked state of the inner frame 12, the engaged portions 83d, 84d are different from the action portions 623c, 624c different from the head portions 623b, 624b engaged with the engaged portions 83d, 84d of the receiving fittings 83, 84. Are in contact with each other so that the inner flange members 623 and 624 are displaced. That is, when the inner frame 12 is closed, the heads 623b and 624b and the engaged portions 83d and 84d are not in contact with each other. For this reason, when the inner frame 12 is closed, it is possible to prevent the heads 623b and 624b from coming into contact with the engaged portions 83d and 84d to be deformed.

  Furthermore, in the present embodiment, the cylinder lock 700 is not configured to move the second sliding rod 625 directly, so there is no need to consider the load during the unlocking operation of the cylinder lock 700 with the key K, and relatively A strong coil spring C2 can be used. As a result, when the inner frame 12 is opened, the force to push the inner frame 12 forward can be increased, and when the inner frame 12 is closed, the inner flange members 623 and 624 (acting portions) that come into contact with the engaged portions 83d and 84d. 623c, 624c) can function as a buffer means for absorbing an impact when the inner frame 12 is closed.

  Further, the lock member 660 is supported by an extending wall portion 603b formed along the front-rear direction and the up-down direction so that the lock member 660 can be pivotally displaced about the shaft hole 660b (shaft pin 663). Yes. That is, since the lock member 660 is configured not to be displaced in the left-right direction, expansion of the lateral width of the locking device 600 can be suppressed, and as a result, a wider installation space such as a game area and various control boards can be secured. it can.

  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 embodiment, the locking mechanism of the inner frame 12 and the locking mechanism of the front frame set 14 are embodied by a single locking device 600. 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 may be omitted.

  Further, when the door body is opened, the door body is automatically pushed forward. In the embodiment, the inner frame 12 as the door body supported by the outer frame 11 as the support body so as to be opened and closed is provided. Adopted to open configuration. For example, the front frame set 14 serving as a door body that is supported by the inner frame 12 serving as a support body so as to be opened and closed may be used.

  Further, the position where the locking device is provided is not limited to the inner frame 12. For example, in a configuration in which the inner frame 12 is pushed out and opened, it may be provided on the outer frame 11, or the front frame set 14 may be provided. In the structure which is pushed out and opened, the front frame set 14 may be provided.

  (B) The configuration of the cylinder lock 700 is not limited to the above embodiment. In the above embodiment, a configuration is adopted in which the cylinder lock 700 is locked when the key K is not inserted, and the sliding displacement of the first sliding rod 609 is restricted by the cam plate 720. For example, a cylinder lock that does not enter the locked state even when the key K is not inserted (the cam plate 720 cannot be displaced) may be employed. Of course, the lock member is not limited to the cylinder lock, but may be operated using a key such as a card key.

  (C) The configuration of the inner flange members 623, 624 and the front flange portions 616, 617, 618 is not limited to the above embodiment. For example, in the above-described embodiment, a configuration in which the inner flange members 623 and 624 are connected to the second sliding rod 625 so as to be capable of rotational displacement is employed. For example, a configuration in which the inner flange members 623 and 624 are slidably displaced in the vertical direction between the locked position and the unlocked position may be employed. In such a case, a configuration in which the inner flange members 623 and 624 are integrally formed with the second sliding rod 625 may be employed.

  For example, as shown in FIG. 27 (a), a flange portion 680 that is obtained by vertically inverting the inner flange members 623 and 624 of the above embodiment is integrally formed above and below the second sliding rod 625, and the inner frame 12 In the locked state, when the second sliding rod 625 is in the locked position, the head portion (engaging portion) 680a of the flange portion 680 is engaged with the engaged portion 84d of the receiving metal member 84, and the inner portion The opening of the frame 12 is restricted. When the inner frame 12 is unlocked, when the cylinder lock 700 is operated and the restriction by the lock member 660 is released, the flange portion 680 (second sliding rod 625) is caused by the tensile force of the coil member C2. It slides upward, and its head 680a is disengaged from the engaged portion 84d of the catch 84. At the same time, the action portion 680b pushes the engaged portion 84d of the catch 84. And as shown in FIG.27 (b), the to-be-engaged part 84d of the metal fitting 84 will completely come out of the collar part 680, and the collar part 680 and the metal fitting 84 will be in a detachment | leave state. At this time, the action portion 680b of the flange portion 680 pushes the engaged portion 84d of the receiving metal member 84, whereby the inner frame 12 is pushed forward, and the inner frame 12 is automatically released.

  When locking the inner frame 12, when the inner frame 12 is closed, first, the action portion 680 b of the flange portion 680 comes into contact with the engaged portion 84 d of the receiving metal member 84. Then, against the tensile force of the coil spring C2, the second sliding rod 625 (the flange portion 680) slides downward, the flange portion 680 returns to the locking position, and the head portion 680a of the flange member 680 is received. It is engaged with the engaged portion 84 d of the metal fitting 84.

  In addition, the number of each flange member such as the inner flange member 623 and each engaged portion such as the receiving metal fitting 83 corresponding thereto is not limited to the number of the above embodiments. For example, it is good also as a structure provided with three or more hook members etc. corresponding to the locking mechanism of the inner frame 12. FIG.

  (D) The configuration of the lock member 660 is not limited to the above embodiment. For example, in the above-described embodiment, the lock member 660 that is rotationally displaced is employed, but the present invention is not limited thereto, and for example, a lock member that is slidably displaced in a substantially horizontal direction may be employed.

  In the above embodiment, when the inner frame 12 is closed, the lock member 660 is automatically displaced to the restricted position by the tensile force of the coil spring C3. Instead of this, for example, the lock member may be displaceable between the restriction position and the restriction release position by the electric driving means when the inner frame 12 is opened and closed. Specific examples include a configuration in which the lock member is displaced by controlling a solenoid or the like according to the detection result of the opening detection switch of the inner frame 12.

  (E) In the above embodiment, the cover member 740 that covers the cam plate 720, the bulging portion 610a of the first sliding rod 609, the bulging portion 625 of the second sliding rod 625, the lock member 660, and the like is attached and fixed. ing. The shape, material, and assembly structure of the cover member are not limited to the above embodiment. Further, the mounting position, size, range, and the like can be changed as appropriate. For example, it is good also as a structure provided with the cover member which covers only the lock member 660, without covering the cam board 720. FIG.

  (F) You may implement as a different type of pachinko machine from the said embodiment. In addition to the pachinko machine, the present invention may be implemented as an arrangement ball machine, various game machines such as a sparrow ball, a slot machine, or a game machine of a type in which a slot machine and a pachinko machine are integrated.

  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 door body supported to be openable and closable with respect to the support body on the front side of the support body;
A gaming machine provided with a locking device that locks the door to the support,
The locking device is
It is attached to one of the support body or the door body,
A plurality of engaging members displaceable to a locking position that can be engaged with an engaged portion provided on the other of the support body or the door body, and an unlocking position that can be detached from the engaged portion;
A linking member displaceable between a first switching position in which the plurality of engaging members are interlocked and the engaging member is the locking position, and a second switching position in which the engaging member is the unlocking position; ,
A biasing member that biases the engagement member toward the unlocking position via the connection member by biasing the connection member toward the second switching position.
By maintaining the connecting member displaced toward the first switching position against the urging force of the urging member, the displacement of the connecting member toward the second switching position and the engagement are maintained. A regulating member that regulates the displacement of the member toward the unlocked position;
A locking member capable of operating the restriction member by a specific operation with a key;
The engaging member is
An engaging portion that is engaged with the engaged portion; and an action portion that can contact the engaged portion separately from the engaging portion;
With the engagement portion engaged with the engaged portion, the displacement of the engagement member toward the unlocked position is restricted by the restriction member via the connecting member, whereby the door It becomes a locked state where the opening of the body is regulated,
In the locked state, when the specific operation is performed on the lock member, the restriction by the restriction member is released, and the connecting member is moved to the second switching position side by the biasing force by the biasing member. And the engaging member is displaced to the unlocked position side,
Due to the displacement operation of the engaging member, the operating portion acts on the engaged portion while the engaging portion is disengaged from the engaged portion, the door body is pushed forward, and the unlocked state is established. A gaming machine characterized by

  According to the means 1, when the door is unlocked by operating the lock member, the door is automatically pushed forward and opened. Thereby, even when the weight of the door body is relatively heavy, a force is applied in the opening direction of the door body, so that the door body can be opened relatively easily. As a result, it is not necessary to perform a troublesome operation such as pulling forward while operating the lock member with one hand and supporting the door body with the other hand, thereby improving convenience.

  Further, since the biasing member (for example, an elastic member such as a coil spring) is configured to bias the plurality of engaging members via the connecting member, a plurality of biasing members corresponding to the respective engaging members. The increase in the number of parts can be suppressed.

  Furthermore, conventionally, since the structure is provided with a biasing member that biases the engaging member directly or indirectly to the locking position side, the load at the time of unlocking operation of the locking member by the key is considered. Therefore, it has been impossible to use a biasing member having a relatively strong biasing force. On the other hand, in the configuration of this means, the lock member is configured to move the regulating member that regulates the engaging member (connecting member), that is, not configured to move the engaging member or the connecting member directly. Therefore, it is not necessary to consider the load at the time of the unlocking operation of the lock member with the key. As a result, as a biasing member that biases the engaging member (connection member), a member having a relatively strong biasing force can be used, and the force for pushing the door body forward when unlocking the door body can be increased. it can.

  The “engagement” of the engagement member (engagement portion) and the engaged portion refers to the engagement between the engagement portion and the engaged portion when the door body is moved in the opening direction. A state that is in a positional relationship. That is, in the locked state of the door body, even when the engaging portion and the engaged portion are in a non-contact state with some play, when the door body is moved in the opening direction, the engaging portion and If the engaged parts come into contact with each other and are in a positional relationship in which they are engaged, it is included in the “engagement”. Conversely, “disengagement” means a positional relationship in which the engaging portion and the engaged portion do not come into contact with each other when the door is moved in the opening direction, or a state in which the door can be opened while being in contact. Say.

  Further, the “displacement” of the predetermined member such as the engaging member is not limited to the linear position change in the vertical direction, for example, the predetermined member pivotally supported so as to rotate, and the posture thereof is changed. It is also included that only the position of a predetermined part such as the engaging portion is changed. Therefore, the “displacement” of the predetermined member can be replaced with the expression “motion” of the predetermined member.

  Mean 2. When the door is closed in a state where the engaging member is in the unlocked position, the urging force of the urging member is caused by the action portion of the engaging member coming into contact with the engaged portion. 2. The gaming machine according to claim 1, wherein the engaging portion is engaged with the engaged portion while the engaging member is displaced toward the locking position against the above.

  According to the above means 2, the action part acting on the engaged part when the door is opened engages with the engaged part even when the door is closed. It becomes the structure by which a door body is locked. As a result, when the door body is locked, it is not necessary to perform a locking operation with a key, and convenience is improved.

  In addition, the engaging member is displaced when the engaged portion comes into contact with an action portion different from the engaging portion engaged with the engaged portion in the locked state of the door body. That is, when the door is closed, the engaging portion and the engaged portion do not collide. In the configuration in which the engaging member itself is in contact with the engaged portion when the door body is closed as in the prior art, the engaging portion may be deformed or the like due to the contact between the two. . If the engaging portion is deformed or the like, there may be a problem that the door body cannot be properly locked.

  Furthermore, as described above, conventionally, the biasing force of the biasing member that biases the engagement member toward the locking position is normally set relatively strong in consideration of the load during the unlocking operation of the locking member with the key. I couldn't. For this reason, it was difficult to absorb the impact at the time of closing of a door body by contact with an engaging part and an engaged part. That is, the drag force of the urging member is weak, and when the door body is closed with force, the door body may collide with the support body violently. In such a case, there is a risk of adversely affecting various members such as an electronic device attached to the door body. In particular, since the weight of the door body tends to increase in recent years, the impact is large, and there is a high possibility that such a problem occurs.

  On the other hand, in the configuration of this means, as described above, the lock member does not directly move the engaging member or the connecting member connected to the engaging member, so it is necessary to consider the load at the time of the unlocking operation. In addition, using an urging member having a relatively strong urging force, the engaging member (acting portion) that comes into contact with the engaged portion can function as a buffering means. As a result, the impact when the door is closed can be sufficiently absorbed by the contact between the engaging member (action portion) and the engaged portion.

Means 3. The regulating member is
While being provided displaceably at a restriction position that restricts displacement of the connecting member toward the second switching position and a restriction release position that releases the restriction,
A second urging member for urging the restricting member toward the restricting position;
When the connecting member is displaced to the second switching position, the restricting member is engaged with a specific part of the connecting member, so that the displacement of the restricting member toward the restricting position is restricted, and the restricting member is Held in the release position,
When the connecting member is displaced to the first switching position, the specific member of the connecting member is disengaged from the restricting member, and the restricting member is moved by the biasing force of the second biasing member. The gaming machine according to means 1 or 2, wherein the gaming machine is displaced to a position.

  According to the means 3, once the restriction by the restricting member is released, the restricting member does not return to the restricting position by the connecting member. Therefore, the connecting member is maintained at the second switching position, and the engaging member is maintained at the unlocked position. it can. Under the configuration of the means 1 and 2, if the engaging member is maintained in the locked position when the door is opened, the engaging portion may collide with the engaged portion.

  In this regard, according to the present means, after the door body is unlocked, the engaging member does not return to the locked position even if the hand is released from the key. It is possible to prevent the engagement member from being deformed without colliding with the joint portion. Further, if the door is closed, the restricting member automatically returns to the restricting position, which is convenient.

  Means 4. The gaming machine according to any one of means 1 to 3, wherein the regulating member is provided so as to be displaceable along a plane along the front-rear direction and the up-down direction.

  As in the above means 4, the restriction member can be slidably displaced in the front-rear direction, or can be rotationally displaced with the left-right direction as the rotation axis, thereby suppressing the displacement of the restriction member in the left-right direction. it can. As a result, the expansion of the lateral width of the locking device can be suppressed, and as a result, the center region (game region or the like) of the door body can be expanded.
