Description

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

  Generally, 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 fixed frame (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. Such a locking device includes a cylinder lock that is operated using a dedicated key, a plurality of hook members that can be engaged with and disengaged from a plurality of engaged members that are provided on a fixed frame, and a cylinder that uses 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 the corresponding engaged member, 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 members via the sliding hooks, and the gaming machine main body can be opened.

  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 of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on any one of the flange members, the operation is transmitted to the other flange member via the sliding rod, and the entire flange member is interlocked and detached from the engaged member. The gaming machine body can be opened.

In order to prevent such an unauthorized unlocking operation, in recent years, for example, a gaming machine provided with a protective cover surrounding an engaged member and a hook member engaged therewith has been proposed (see, for example, Patent Document 1). In this way, it is very difficult to open the gaming machine body unless the cylinder lock is unlocked from the front side of the gaming machine with a dedicated key.

  However, in game halls, in various situations such as when a gaming machine is introduced or when a cylinder lock breaks down, replacement of the cylinder lock itself or the key code (keyhole shape) of the cylinder lock that matches the key used in the game hall Changes are made. In a general cylinder lock, for example, a key code that matches the key to be newly set can be obtained by performing a predetermined operation such as inserting a key to be newly set into a keyhole while pressing a predetermined reset pin and performing a rotation operation. It can be.

  However, not only when the cylinder lock is broken or when the key is lost, but also when the cylinder lock is not changed or the key code is not changed properly, the key code is set incorrectly or forgotten to be set, or the cylinder lock is defective. If the gaming machine main body is closed while holding, the cylinder lock cannot be operated to open the gaming machine main body.

  When such a problem occurs, if the protective cover is provided, the hook member is manually moved from the back side of the gaming machine as in the conventional countermeasure, and the engaged state with the engaged member is released. Since it is also impossible, there is a risk that the gaming machine main body cannot be opened at all.

  On the other hand, when the protective cover is provided so as to be rotatable between the shielding position and the non-shielding position as in the invention described in Japanese Patent Laid-Open No. 2001-120817 (see FIG. 3), unauthorized unlocking is performed. The defense performance against is reduced.

  Such a problem is not limited to pachinko machines, but also applies to other gaming machines that include a locking mechanism that locks the door body and the fixed frame.

  The present invention has been made to solve the above-described problems and the like, and its purpose is a game capable of ensuring both sufficient defense performance against unauthorized unlocking and improving maintainability. Is to provide a machine.

In order to achieve the above object, a gaming machine according to the present invention provides:
A fixed frame constituting the outer shell,

  Furthermore, a plurality of reinforcing ribs 801m are provided on the outer side of the right wall portion 801e of the resin cover 801 along the front-rear direction from each receiving portion 801k to the rear wall portion 801a.

  On the other hand, a plurality of slits 801p are intermittently provided from the rear wall portion 801a to the left wall portion 801d (receiving portion 801j) so as to surround a substantially rectangular range in the rear view. As a result, a portion surrounded by the slit 801p is defined as a lid 801q. The lid 801q can be separated from the main body of the resin cover 801 by cutting a plurality of broken portions 801r left as connecting portions between the adjacent slits 801q.

  Next, a procedure for assembling the receiving metal 83 and the resin cover 801 will be described. The assembly of both is performed at a stage prior to attaching the metal fitting 83 to the inner wall surface of the right side frame constituting portion 11d of the outer frame 11.

  In the present embodiment, the resin cover 801 is fitted into the opening on the rear side of the receiving metal 83. When the wall portions 801b to 801e of the resin cover 801 are inserted while elastically deforming the locking pieces 801f to 801h, the locking pieces 801f to 801h are restored when the wall reaches the predetermined position. The claws are locked in the locking holes 83k to 83m of the metal fitting 83. At the same time, the left wall portion 83d of the metal fitting 83 is inserted into the receiving portion 801j of the left wall portion 801d of the resin cover 801, and the right wall portion 83e of the metal fitting 83 contacts or is inserted into the receiving portion 801k of the right wall portion 801e. Is included. This completes the assembly of both. Note that, due to the structure of the metal fitting 83, slit-shaped gaps are formed at the four corners where the upper, lower, left and right wall parts 83b to 83e intersect. However, when the resin cover 801 is assembled, these gaps are formed on the upper and lower sides of the resin cover 801. Almost the whole is closed by the four corner portions where the left and right wall portions 801b to 801e intersect. Thereby, the approach to the inside of a wire etc. is prevented.

  Subsequently, the metal fitting 83 is fixed to the inner wall surface of the right side frame constituting portion 11d of the outer frame 11 with the resin cover 801 assembled as described above. Specifically, in a state where the attachment portions 83f and 83g of the metal fitting 83 are aligned, the screw holes 83h are fixed by screwing screws 799 from the outside of the right side frame constituting portion 11d of the outer frame 11.

  Once the receiving metal fitting 83 is fixed, the engaging claw of the engaging piece 801h of the resin cover 801 that is engaged with the right wall 83e of the receiving metal fitting 83 cannot be pushed from the outside of the receiving metal fitting 83. The stopped state cannot be released. That is, in a state where the receiving metal fitting 83 is fixed, the resin cover 801 cannot be removed unless it is broken.

  Next, parts related to the locking mechanism of the front frame set 14 will be described. The front flange members 616, 617, 618 constituting the locking mechanism of the front frame set 14 correspond to the flange insertion holes 605, 606, 607 of the mounting plate 602 on the outer side of the inner frame 12 of the sliding rod 610. Are arranged at three locations, an upper portion, a middle portion, and a lower portion.

  The forward flange members 616, 617, 618 are mainly composed of base portions 616a, 617a, 618a disposed in the base frame 601, projecting portions 616b, 617b, 618b protruding forward from the base portions 616a, 617a, 618a, It consists of substantially triangular heads 616c, 617c, 618c provided to taper forward on the front end side of the protrusions 616b, 617b, 618b.

  As described above, the attachment plate 602 is formed with the flange insertion holes 605, 606, 607 corresponding to the front flange members 616, 617, 618, and the protrusion 616b from the flange insertion holes 605, 606, 607. , 617b, 618b and only the heads 616c, 617c, 618c protrude forward. The upper ends of the heads 616c, 617c, and 618c protrude upward from the protrusions 616b, 617b, and 618b, and the protrusions function as locking portions as will be described later.

  The base portions 616a, 617a, 618a of the front rod members 616, 617, 618 are arranged along the mounting side wall portions 616d, 617d, 618d disposed along the mounting plate 602 and the support plate 603 (sliding rod 610). And provided support side wall portions 616e, 617e, and 618e. The protrusions 616b, 617b, 618b extend from the outer edge of the inner side wall 12 of the mounting side wall portions 616d, 617d, 618d, and are formed with a step from the supporting side wall portions 616e, 617e, 618e. ing.

  Further, attachment side guide holes 616f, 617f, and 618f that are elongated in the vertical direction are formed below the attachment side wall portions 616d, 617d, and 618d. The guide pins 641, 642, 643 inserted from the inside (rear side) of the base frame 601 are fixed to the mounting plate 602 with respect to the mounting side guide holes 616f, 617f, 618f.

  Corresponding to the front flange members 616, 617, and 618, the upper, middle, and lower portions of the sliding rod 610 and the support plate 603 have inner guide holes 645, 646, 647 and outer guide holes 648, 649, 650, respectively. Is formed. Each of the guide holes 645 to 650 has an oval shape that is long in the vertical direction. The guide pins inserted from the outside of the support plate 603 (inner side of the inner frame 12) into the inner guide holes 645, 646, 647 of the sliding rod 610 and the outer guide holes 648, 649, 650 of the support plate 603. 651, 652, and 653 are fixed to the forehead members 616, 617, and 618 (support side wall portions 616e, 617e, and 618e). Accordingly, the front rod members 616, 617, and 618 are engaged with the base frame 601 (support plate 603) and the sliding rod 610 so as to be relatively displaceable in the vertical direction, and the sliding rod 610 slides. It can slide in conjunction.

  With the above configuration, the forward saddle members 616, 617, and 618 are restricted from moving in the left-right direction and in the front-rear direction by various guide pins such as the guide pin 641, the mounting plate 602, the flange portion 603a, and the like. It can slide up and down.

  The front flange members 616, 617, and 618 are biased upward by the coil springs C3, C4, and C5. More specifically, one end of each of the coil springs C3, C4, C5 is hook portions 616h, 617h, which are provided on the front flange members 616, 617, 618 (support side wall portions 616e, 617e, 618e of the base portions 616a, 617a, 618a). The other end is hung on hooks 637, 638, and 639 provided on the mounting plate 602. Thereby (by the tensile force of the coil springs C3, C4, C5), the forward flange members 616, 617, 618 are normally biased upward. That is, the forward flange members 616, 617, and 618 are normally held in a state where the guide pins 651, 652, and 653 are in contact with the upper edge portions of the outer guide holes 648, 649, and 650 of the support plate 603.

  It should be noted that the position where the guide pins 651, 652, 653 abut on the upper edge portions of the outer guide holes 648, 649, 650 of the support plate 603 is within the sliding range of the front flange members 616, 617, 618. The members 616, 617, and 618 are in positions where they are locked to the metal fittings 91, 92, and 93. That is, this position corresponds to the locking position (reference position) of the front heel member 616, 617, 618. At this time, in the front rod members 616, 617, and 618, the lower edge portions of the attachment-side guide holes 616f, 617f, and 618f abut on the guide pins 641, 642, and 643 fixed to the sliding rod 610.

  On the other hand, the positions where the guide pins 651, 652, 653 abut against the lower edge portions of the outer guide holes 648, 649, 650 of the support plate 603 are the positions where the front flange members 616, 617, 618 are received by the metal fittings 91, 92, It becomes a position to leave from 93. That is, this position corresponds to the non-locking position of the front heel member 616, 617, 618. At this time, in the front collar members 616, 617, and 618, the upper edge portions of the attachment side guide holes 616f, 617f, and 618f abut on the guide pins 641, 642, and 643 fixed to the sliding collar 610.

  Here, the structure of the metal fittings 91, 92, 93 will be described in detail. The brackets 91, 92, 93 include attachment portions 91 a, 92 a, 93 a that are fixed to the back side of the front frame set 14, and extension portions 91 b, 92 b that extend backward from the attachment portions 91 a, 92 a, 93 a, 93b, engaging portions 91c, 92c, 93c extending from the rear end portions of the extending portions 91b, 92b, 93b to the inner side of the front frame set 14 and engaged with the front saddle members 616, 617, 618; It has.

  In addition, insertion holes 91d, 92d, and 93d are formed in the attachment portions 91a, 92a, and 93a in correspondence with the forward flange members 616, 617, and 618, and the forward flange members 616, 617, and 618 are received by the receiving metal 91. , 92, 93, the tips of the heads 616c, 617c, 618c of the front heel members 616, 617, 618 are inserted into the insertion holes 91d, 92d, 93d (see FIG. 23). ).

  In addition, the sliding rod 610 is normally at a position where the lower edge portions of the inner guide holes 625 and 626 are substantially at the same height as the lower edge portions of the outer guide holes 627 and 628 of the support plate 603, and The upper edge portions of the guide holes 645, 646, and 647 are held at positions that are substantially the same height as the upper edge portions of the outer guide holes 648, 649, and 650 of the support plate 603. This position corresponds to the reference position of the sliding rod 610. When the sliding rod 610 is in the reference position, the lower edge portion of the inner guide holes 625 and 626 engages with the guide pins 631 and 632 of the inner rod members 613 and 614, that is, the coil springs C1 and C2 are pulled. The upward movement is suppressed by the force, and the upper edge portions of the inner guide holes 645, 646, 647 are engaged with the guide pins 651, 652, 653 of the front member 616, 617, 618. That is, the downward movement is suppressed by the tensile force of the coil springs C3, C4, and C5. When a cylinder lock 700 described later is operated, the cylinder lock 700 is slid upward or downward against the tensile force of the coil spring C1 or the like.

  A cylinder lock 700 as a lock member is attached to the wide portion 602b 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. 18, the cylinder lock 700 includes a cylinder body 701 having a substantially cylindrical shape, a lock shaft 703 provided inside the cylinder body 701 and having a key hole 702 inside, and an outer periphery of the cylinder body 701. And an outer cylinder 704 provided.

  The cylinder lock 700 is fixed by screwing the flange portion 705 to the back side of the mounting plate 602 with the cylinder body 701 inserted through the mounting hole 602c of the mounting plate 602.

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

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

  With the above configuration, when the key K is inserted into the keyhole 702, the pins 714 and the like move up and down along the concave and convex shapes on both the upper and lower sides of the key K. When the key K is completely inserted, each pin 714 enters the key K groove as shown in FIG. 19, 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 rotational movement of the key K inserted into the key hole 702 to the sliding rod 610 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.

  Accordingly, an upper engagement hole 725 through which the upper engagement claw 720a can enter and exit and a lower engagement hole 726 through which the lower engagement claw 720b can enter and exit are formed in the bulging portion 610a of the sliding rod 610. Has been. Further, a through hole 730 is formed in the support plate 603 so as not to hinder the operation of both the engaging claws 720a and 720b.

  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, as shown in FIG. The tip of the claw 720a is inserted into the upper engagement hole 725 of the sliding rod 610, and the tip of the lower engagement claw 720b is inserted into the lower engagement hole 726 of the sliding rod 610.

  Further, as described above, the cylinder lock 700 according to the present embodiment is in a state where the lock shaft 703 and the cam plate 720 cannot be rotated when the key K is not inserted into the key hole 702 (a locked state in which the lock cannot be displaced). Therefore, when the cam plate 720 is at the reference position, the sliding of the sliding rod 610 is restricted by the engaging claws 720a and 720b. For example, if an external force in the unlocking direction is applied to the sliding rod 610 by improperly hooking a wire rod or the like on the sliding rod 610 at the reference position without using the key K, The joint claws 720a and 720b are hooked on the edges of the engaging holes 725 and 726 of the sliding rod 610, and the sliding displacement of the sliding rod 610 in the unlocking direction is substantially excluding the play length of the engaging hole 725 and the like. Regulated by

  A cam cover 740 is attached and fixed to the locking device 600 by a fixing means such as a screw so as to cover the back side of the cylinder lock 700. The cam cover 740 covers the engaging portion between the cam plate 720 and the sliding rod 610, and covers substantially the entire bulging portion 610 a (including the upper and lower stepped portions) of the sliding rod 610.

  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. When the inner frame 12 is locked, the sliding barb 610 takes the reference position, so that the heads of the inner bark members 613 and 614 with respect to the metal fittings 83 fixed to the inner side of the outer frame 11 as described above. 613c and 614c are locked, and the opening of the inner frame 12 is restricted (see FIG. 22). However, in FIG. 22, for convenience, a partial cross-sectional view with the resin cover 801 removed is shown.

  When unlocking the inner frame 12, the key K inserted into the key hole 702 of the cylinder lock 700 is rotated in the clockwise direction in FIG. As a result, as shown in FIGS. 20A and 20B, the cam plate 720 rotates in the same direction, and the lower engagement claw 720 b moves to the upper edge of the lower engagement hole 726 of the sliding rod 610. The sliding rod 610 slides upward so that it comes into contact and is pushed up by the lower engaging claw 720b.

  When the sliding rod 610 slides upward, the guide pins 631 and 632 are pulled up by the lower edge portions of the inner guide holes 625 and 626 of the sliding rod 610, and the inner rod is resisted against the tensile force of the coil springs C1 and C2. The members 613 and 614 slide upward. As a result, the engagement between the inner flange members 613 and 614 and the respective receiving fittings 83 is released, and the opening of the inner frame 12 is allowed.

  When the front collar members 616, 617, and 618 are in the locking position (reference position), they are located below the inner guide holes 645, 646, and 647 of the sliding collar 610 with which the guide pins 651, 652, and 653 are engaged. The guide pins 651, 652, and 653 have a space for relative displacement. Thus, even when the sliding rod 610 is slid upward, the front rod members 616, 617, and 618 are not slid and can be maintained as they are.

  On the other hand, when the inner frame 12 is locked, the inner frame 12 can be locked without using the key K. More specifically, when the inner frame 12 in the open state is closed, the inclined portions of the head portions 613c and 614c of the inner flange members 613 and 614 are located on the lower side (front wall portion 83a) of the hole portions 83j of the receiving metal fittings 83. To touch. When the inner frame 12 is further closed, the inner flange members 613 and 614 are pushed upward, and once slide against the tensile force of the coil springs C1 and C2. Thereafter, when the heads 613c and 614c of the inner flange members 613 and 614 exceed the front wall portion 83a, the inner flange members 613 and 614 return to their original positions by the tensile force of the coil springs C1 and C2, and the front wall portion 83a Locked to the back side. As a result, locking is completed and the opening of the inner frame 12 is restricted.

  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 sliding hook 610 takes the reference position, so that the receiving metal fittings 91, 92, 93 (engaging portions 91c, 92c, 93c) attached to the front frame set 14 as described above. ), The heads 616c, 617c, and 618c of the front saddle members 616, 617, and 618 are locked, and the opening of the front frame set 14 is restricted (see FIG. 23). In the state in which the front flange members 616, 617, and 618 are engaged with the metal fittings 91, 92, and 93, the tips of the head portions 616c, 617c, and 618c are inserted into the insertion holes 91d, 92d, and 92d of the attachment portions 91a, 92a, and 93a, respectively. It will be in the state inserted in 93d.

  When unlocking the front frame set 14, the key K inserted into the key hole 702 of the cylinder lock 700 is rotated in the counterclockwise direction in FIG. As a result, as shown in FIGS. 21A and 21B, the cam plate 720 is rotated in the same direction, and the upper engagement claw 720a is moved to the lower edge of the upper engagement hole 725 of the sliding rod 610. The sliding rod 610 slides downward so as to come into contact with the upper engaging claw 720a.

  When the sliding rod 610 slides downward, the guide pins 651, 652, 653 are pulled down by the upper edge portions of the inner guide holes 645, 646, 647 of the sliding rod 610, and the tensile force of the coil springs C3, C4, C5 Against this, the forehead members 616, 617, 618 slide downward. As a result, the engagement between the front saddle members 616, 617, and 618 and the metal fittings 91, 92, and 93 is released, and the opening of the front frame set 14 is allowed.

  When the inner flange members 613 and 614 are in the locking position (reference position), the guide pins 631 and 626 are provided in the upper portions of the inner guide holes 625 and 626 of the sliding rod 610 with which the guide pins 631 and 632 are engaged. A space in which 632 is relatively displaced is secured. Thus, even when the sliding rod 610 is slid downward, the inner flange members 613 and 614 are not slid and can be maintained as they are.

  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 saddle members 616, 617, and 618 are engaged portions 91c of the receiving brackets 91, 92, and 93. , 92c, 93c are in contact with the lower side. Further, when the front frame set 14 is closed, the front flange members 616, 617, and 618 are pushed downward, and once slide against the tensile force of the coil springs C3, C4, and C5. After that, when the head portions 616c, 617c, 618c of the front saddle members 616, 617, 618 exceed the engaging portions 91c, 92c, 93c, the front saddle members 616, 617, 618 are caused by the tensile force of the coil springs C3, C4, C5. Returns to its original position and is locked to the engaging portions 91c, 92c, 93c. At this time, the tips of the heads 616c, 617c, 618c are inserted into the insertion holes 91d, 92d, 93d of the attachment portions 91a, 92a, 93a. Thereby, locking is completed and the opening of the front frame set 14 is restricted.

  Furthermore, in this embodiment, when the cylinder lock 700 cannot be operated and the inner frame 12 cannot be opened, such as when the cylinder lock 700 is out of order, the inner collar member 613 directly from the back side of the pachinko machine 10. The inner frame 12 is opened by operating 614.

  When the inner frame 12 is in a locked state, the head 613c (614c) of the flange member 613 (614) is usually covered with the receiving metal fitting 83 and the resin cover 801 as shown in FIG. . Therefore, the inner collar member 613 (614) cannot be directly operated. Therefore, in order to operate directly, first, as shown in FIG. 29B, the breaking portion 801r is cut with a tool such as a nipper, and the lid portion 801q is separated from the main body portion of the resin cover 801. Thus, an opening 801s is formed in the resin cover 801, and the inner flange member 613 (614) can be directly operated through the opening 801s. When the inner flange member 613 (614) is pushed upward, only the inner flange member 613 (614) slides upward against the coil spring C1 (C2) without sliding the sliding rod 610. The engaged state is released.

  After that, the receiving metal fitting 83 is once removed from the outer frame 11, and the used resin cover 801 is removed. Then, a new resin cover 801 is attached according to the procedure described above, and the metal fitting 83 is attached to the outer frame 11 again.

  As described above in detail, in this embodiment, since the eaves members 613 and 614 are covered with the receiving metal fitting 83 and the resin cover 801, it is difficult to hook a wire or the like to the eaves members 613 and 614. As a result, it is possible to prevent a direct unlocking operation with respect to the eaves members 613 and 614 using a wire or the like, that is, an unauthorized unlocking operation.

  Furthermore, for a valid reason such as when the cylinder lock 700 is broken, the hook member 613, 614 must be operated directly from the back side of the pachinko machine 10 without using the key K to release the engaged state. In such a case, the lid 801q of the resin cover 801 can be cut off, and the work can be performed through the opening 801s formed there. That is, it is possible to more surely prevent fraud without disturbing the efficiency of work performed for a valid reason.

  In addition, when the lid portion 801q is separated, the trace remains on the resin cover 801. Therefore, in the unlikely event that an illegal act is performed by opening the cover 801q, it is possible to detect the illegal act 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.

  Further, when the receiving metal fitting 83 is fixed to the outer frame 11 in a state where the resin cover 801 is assembled, the resin cover 801 cannot be removed. Generally, after the pachinko machine 10 is installed in the island facility of the game hall, other pachinko machines 10 and the like are arranged adjacent to each other, so the screw 799 is attached from the outside of the right side frame constituting portion 11d of the outer frame 11.

The bulging concave portions 916g, 917g, and 918g have a function as a guard portion, and prevent the entry of the wire material or the like from the outside to the protruding portions 919g, 920g, and 921g side of the front lock members 919, 920, and 921. In contrast, it makes it difficult to hook the wire.

  It should be noted that the position where the guide pins 951, 952, 953 abut on the upper edge portions of the outer guide holes 948, 949, 950 of the support plate 903 is within the sliding range of the front wing members 916, 917, 918. The members 916, 917, and 918 are in positions where they are locked to the receiving brackets 91, 92, and 93. That is, this position corresponds to the engagement position (reference position) of the front heel members 916, 917, and 918.

  On the other hand, the positions at which the guide pins 951, 952, and 953 abut against the lower edge portions of the outer guide holes 948, 949, 950 of the support plate 903 are the front flange members 916, 917, 918 are the receiving brackets 91, 92, It becomes a position to leave from 93. That is, this position corresponds to the disengagement position of the front heel members 916, 917, and 918.

  Here, the structure of the metal fittings 91, 92, 93 will be described. As in the first embodiment, the brackets 91, 92, and 93 are attached to the back side of the front frame set 14 and extend backward from the attachment portions 91 a, 92 a, and 93 a. Extending from the extended portions 91b, 92b, 93b and the rear end portions of the extended portions 91b, 92b, 93b to the inward side of the front frame set 14, the front flange members 916, 917, 918 are engaged. Engaging portions 91c, 92c, 93c are provided.

  The mounting portions 91a, 92a, and 93a are formed with insertion holes 91d, 92d, and 93d corresponding to the front flange members 916, 917, and 918. , 92, 93, the tips of the heads 916c, 917c, 918c of the front heel members 916, 917, 918 are inserted into the insertion holes 91d, 92d, 93d (see FIG. 41). ).

  Further, through holes 91e, 92e, and 93e are formed in the engaging portions 91c, 92c, and 93c of the metal fittings 91, 92, and 93 in correspondence with the front lock members 919, 920, and 921, respectively. , 917, 918 are engaged with the metal fittings 91, 92, 93, the upper pieces 919b, 920b, 921b of the front lock members 919, 920, 921 are inserted into the insertion holes 91e, 92e, 93e. A state is reached (see FIG. 41).

  In addition, the sliding rod 910 is normally positioned at a position where the lower edge portions of the inner guide holes 925 and 926 are substantially at the same height as the lower edge portions of the outer guide holes 927 and 928 of the support plate 903 and The upper edge portions of the guide holes 945, 946, 947 are held at positions that are substantially the same height as the upper edge portions of the outer guide holes 948, 949, 950 of the support plate 903. This position corresponds to the reference position of the sliding rod 910. When the sliding rod 910 is in the reference position, the lower edge portions of the inner guide holes 925 and 926 are engaged with the guide pins 931 and 932 of the inner rod members 913 and 914, that is, the coil springs E1 and E2 are pulled. The upward movement is suppressed by the force, and the upper edge portions of the inner guide holes 945, 946, 947 are engaged with the guide pins 951, 952, 953 of the front rod members 916, 917, 918. That is, the downward movement is suppressed by the tensile force of the coil springs E3, E4, E5. When the cylinder lock 700 is operated, the cylinder lock 700 slides upward or downward against the tensile force of the coil spring E1 or the like.

  A cylinder lock 700 as a lock member is attached to the wide portion 902b of the attachment plate 902, as in the first embodiment, and the front side thereof is exposed to the front side of the front frame set 14. In addition, a cam plate 720 as an engaging member that transmits the rotational movement of the key K (see FIG. 18 or the like) inserted into the key hole 702 to the sliding rod 910 is fixed to the rear end portion of the cylinder lock 700. Yes. The cam plate 720 includes a pair of upper and lower upper engaging claws 720a and lower engaging claws 720b.

  Accordingly, an upper engagement hole 975 through which the upper engagement claw 720a can enter and exit and a lower engagement hole 976 through which the lower engagement claw 720b can enter and exit are formed in the bulging portion 910a of the sliding rod 910. Has been.

  When the key K is not inserted into the key hole 702 of the cylinder lock 700 and the cam plate 720 is at the reference position, as shown in FIG. 30, the tip of the upper engagement claw 720a is moved by the sliding rod 910. The upper engagement hole 975 is inserted, and the tip of the lower engagement claw 720b is inserted into the lower engagement hole 976 of the sliding rod 910.

  Similarly to the first embodiment, the cylinder lock 700 of the present embodiment is in a state in which the cam plate 720 cannot be rotated when the key K is not inserted into the key hole 702 (a locked state in which the cam plate 720 cannot be displaced). ) For this reason, when the cam plate 720 is at the reference position, the sliding of the sliding rod 910 is restricted by the engaging claws 720a and 720b. For example, if an external force in the unlocking direction is applied to the sliding rod 910 by improperly hooking a wire rod or the like on the sliding rod 910 at the reference position without using the key K, The joint claws 720a and 720b are hooked on the edge portions of the engaging holes 975 and 976 of the sliding rod 910, and the sliding displacement of the sliding rod 910 in the unlocking direction is substantially excluding the play length of the engaging hole 975 and the like. Regulated by

  A cam cover 940 is attached and fixed to the locking device 900 by a fixing means such as a screw so as to cover the back side of the cylinder lock 700. The cam cover 940 covers the engaging portion between the cam plate 720 and the sliding rod 910, and also covers substantially the entire bulging portion 910a (including the upper and lower stepped portions) of the sliding rod 910.

  Next, the operation of the locking device 900 will be described in detail. First, locking and unlocking of the inner frame 12 will be described in detail. When the inner frame 12 is locked, the sliding barb 910 takes the reference position, so that the heads of the inner bark members 913 and 914 with respect to the receiving metal fittings 830 fixed to the inner side of the outer frame 11 as described above. 913c and 914c are locked, and the opening of the inner frame 12 is restricted (see FIGS. 40 and 43). In a state where the inner flange members 913, 914 are engaged with the respective metal fittings 830, the lower pieces 923c, 924c of the inner lock members 923, 924 are inserted into the lock hole portions 830p (see FIG. 40). ). However, in FIG. 40, a partial cross-sectional view of the receiving metal fitting 830 is shown for convenience.

  Temporarily, when the inner frame 12 is in the open state, a wire rod or the like is hooked on the protrusion 913b (914b) or the head 913c (914c) of the inner collar member 913 (914) in the locking position, and the sliding collar 910 is interposed therebetween. First, when an external force in the unlocking direction (upward) is applied to the inner flange member 913 (914), the inner flange member 913 (914) slides upward as shown in FIG. The inner lock member 923 (924) slides upward. At this time, since the inner lock member 923 (924) is attracted to the mounting plate 902 side (forward and downward) by the tensile force of the coil spring E1 (E2), it slides upward while maintaining the normal reference posture. . The state in which the reference posture is maintained corresponds to the first state of the inner lock member 923 (924) in the present embodiment.

  Accordingly, in the locked state of the inner frame 12, the same unlocking operation as described above is performed illegally by hooking a wire or the like to the inner collar member 913 (914) in the locking position without using the key K. In this case, the lower piece 923c (924c) of the inner lock member 923 (924) is hooked on the front wall 830a of the receiving metal fitting 830. That is, even if the inner collar member 913 (914) is slid in the unlocking direction, its movement is substantially restricted except for play such as the lock hole portion 830p. Of course, the play amount of the lock hole portion 830p is such that the inner hook member 913 (914) has a play amount even when the lower piece 923c (924c) of the inner lock member 923 (924) is in contact with the front wall portion 830a of the receiving metal fitting 830. The head 913 c (914 c) is set so as not to be detached from the receiving metal fitting 830. As a result, the inner flange member 913 (914) is not displaced to the non-locking position, and the opening of the inner frame 12 is not allowed.

  When the inner frame 12 is normally unlocked, the key K inserted into the key hole 702 of the cylinder lock 700 is rotated in the clockwise direction. As a result, as shown in FIGS. 38A and 38B, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b moves to the upper edge of the lower engagement hole 976 of the sliding rod 910. The sliding rod 910 slides upward in contact with the lower engaging claw 720b.

  When the sliding rod 910 slides upward, as shown in FIG. 45 (a), first, the front action piece 910b (910c) of the sliding rod 910 is the projection 923g (924g) of the inner lock member 923 (924). And push it upward. Then, the inner lock member 923 (924) is rotationally displaced against the tensile force of the coil spring E1 (E2), and the lower piece 923c (924c) is slightly retracted forward (mounting plate 902 side). It becomes. This state corresponds to the second state of the inner lock member 923 (924) in the present embodiment. If it will be in this state, it will be in the state which the lower piece part 923c (924c) pulled out from the lock hole part 830p of the metal fitting 830, and a locked state is cancelled | released.

  Further, when the sliding rod 910 slides upward, the guide pin 931 (932) is pulled up by the lower edge portion of the inner guide hole 925 (926) of the sliding rod 910, and as shown in FIG. The inner flange member 913 (914) slides upward against the tensile force of the coil spring E1 (E2). At this time, the inner lock member 923 (924) slides upward together with the inner collar member 913 (914). Thereby, the engagement between the inner flange member 913 (914) and the metal fitting 830 is released, and the opening of the inner frame 12 is allowed.

  When the front flange members 916, 917, and 918 are in the locking position (reference position), the lower portions of the inner guide holes 945, 946, and 947 of the sliding flange 910 engaged with the guide pins 951, 952, and 953 The guide pins 951, 952, 953 and the rear action pieces are arranged on the upper parts of the bulging recesses 916 g, 917 g, 918 g of the front hook members 916, 917, 918 into which the rear action pieces 910 d, 910 e, 910 f are inserted. Spaces for relative displacement of 910d, 910e, and 910f are secured. Thus, even when the sliding rod 910 is slid upward, the front rod members 916, 917, and 918 are not slid and can be maintained as they are.

  On the other hand, when the inner frame 12 is locked, the inner frame 12 can be locked without using the key K. More specifically, when the inner frame 12 in the open state is closed, the inclined portions of the head portions 913c, 914c of the inner flange members 913, 914 are the lower sides (front wall portions 830a) of the hole portions 830j of the respective metal fittings 830. To touch. When the inner frame 12 is further closed, the inner flange members 913 and 914 are pushed upward, and once slide against the tensile force of the coil springs E1 and E2. At this time, the inner lock members 923 and 924 abut against the front wall portion 830a and are rotationally displaced. Thereafter, when the head portions 913c, 914c of the inner flange members 913, 914 exceed the front wall portion 830a, the inner flange members 913, 914 return to their original positions by the tensile force of the coil springs E1, E2, and the front wall portion 830a Locked to the back side. When the inner flange members 913, 914 return to their original positions, the inner lock members 923, 924 also lower downward to return to their original positions, and the lower piece portions 923c, 924c are inserted into the lock hole portions 830p. As a result, the locking is completed, the opening of the inner frame 12 is restricted, and the inner lock members 923 and 924 are locked (locked state).

  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 sliding hook 910 takes the reference position, so that the receiving brackets 91, 92, 93 (engaging portions 91c, 92c, 93c) attached to the front frame set 14 as described above. ), The heads 916c, 917c, and 918c of the front saddle members 916, 917, and 918 are locked, and the opening of the front frame set 14 is restricted (see FIGS. 41 and 43). In the state in which the front flange members 916, 917, and 918 are engaged with the metal fittings 91, 92, and 93, the tips of the head portions 916c, 917c, and 918c are inserted into the insertion holes 91d, 92d, and 92d of the attachment portions 91a, 92a, and 93a. The upper piece portions 919b, 920b, 921b of the front lock members 919, 920, 921 are inserted into the insertion holes 91e, 92e, 93e of the engaging portions 91c, 92c, 93c. A state is reached (see FIG. 41).

  Temporarily, when the front frame set 14 is in an open state, a wire or the like is hooked on the protruding portion 916b (917b, 918b) or the head 916c (917c, 918c) of the front heel member 916 (917, 918) in the locking position. When the external force in the unlocking direction (downward) is applied to the front collar member 916 (917, 918) without the sliding collar 910, the front collar member 916 (917, 918) is moved as shown in FIG. While sliding downward, the front lock member 919 (920, 921) slides downward in conjunction with this. At this time, the front lock member 919 (920, 921) is attracted to the mounting plate 902 side (forward and upward) by the tensile force of the coil spring E3 (E4, E5). To slide.

  Therefore, in the locked state of the front frame set 14, without using the key K, the unlocking similar to the above is performed illegally by hooking the wire rod or the like on the forward member 916 (917, 918) in the locking position. When the operation is performed, the upper piece 919b (920b, 921b) of the front lock member 919 (920, 921) is inserted into the insertion hole 91e of the engaging portion 91c (92c, 93c) of the metal fitting 91 (92, 93). (92e, 93e) will be caught on the lower edge. That is, even if the front heel member 916 (917, 918) is slid in the unlocking direction, its movement is substantially restricted except for play such as the insertion hole 91e (92e, 93e). Of course, the play amount of the insertion hole 91e (92e, 93e) is such that the upper piece 919b (920b, 921b) of the front lock member 919 (920, 921) is inserted into the insertion hole 91e (92e) of the engagement portion 91c (92c, 93c). , 93e) is set such that the head 916c (917c, 918c) of the forward saddle member 916 (917, 918) does not detach from the catch 91 (92, 93) even in a state where it abuts against the lower edge portion. . As a result, the front saddle member 916 (917, 918) is not displaced to the non-locking position, and the opening of the front frame set 14 is not allowed.

  When the front frame set 14 is normally unlocked, the key K inserted into the key hole 702 of the cylinder lock 700 is rotated counterclockwise. As a result, as shown in FIGS. 39A and 39B, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a moves to the lower edge of the upper engagement hole 975 of the sliding rod 910. The sliding rod 910 slides downward so as to come into contact with the upper engaging claw 720a.

  When the sliding rod 910 slides downward, as shown in FIG. 47 (a), first, the rear action piece 910d (910e, 910f) of the sliding rod 910 is the protrusion of the front lock member 919 (920, 921). Touch 919g (920g, 921g) and push it down. Then, the front lock member 919 (920, 921) is rotationally displaced against the tensile force of the coil spring E3 (E4, E5), and the upper piece portion 919b (920b, 921b) is rearward (flange portion 903a side). ) Slightly retracted. In this state, the upper piece 919b (920b, 921b) is pulled out from the insertion hole 91e (92e, 93e) of the receiving metal fitting 91 (92, 93), and the locked state is released.

  Further, when the sliding rod 910 slides downward, as shown in FIG. 47 (b), guide pins 951 (952, 953) are formed by the upper edges of the inner guide holes 945 (946, 947) of the sliding rod 910. Is pulled down, and the forehead member 916 (917, 918) slides downward against the tensile force of the coil spring E3 (E4, E5). At this time, the front lock member 919 (920, 921) slides downward together with the front collar member 916 (917, 918). As a result, the engagement between the front collar member 916 (917, 918) and the catch 91 (92, 93) is released, and the opening of the front frame set 14 is allowed.

  When the inner flange members 913 and 914 are in the locking position (reference position), the upper portions of the inner guide holes 925 and 926 of the sliding rod 910 with which the guide pins 931 and 932 are engaged, or the sliding rod 910 Spaces for relative displacement of the guide pins 931 and 932 and the front action pieces 910b and 910c are secured below the notch recesses 913d and 914d of the inner flange members 913 and 914 into which the front action pieces 910b and 910c are inserted. Thus, even when the sliding rod 910 is slid downward, the inner flange members 913 and 914 are not slid and can be maintained as they are.

  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 916c, 917c, and 918c of the front saddle members 916, 917, and 918 are engaged portions 91c of the receiving brackets 91, 92, and 93. , 92c, 93c are in contact with the lower side. Further, when the front frame set 14 is closed, the front flange members 916, 917, and 918 are pushed downward, and once slide against the tensile force of the coil springs E3, E4, and E5. At this time, the front lock members 919, 920, and 921 come into contact with the back surfaces of the engaging portions 91c, 92c, and 93c and are rotationally displaced. After that, when the head portions 916c, 917c, and 918c of the forehead members 916, 917, and 918 exceed the engaging portions 91c, 92c, and 93c, the forehead members 916, 917, and 918 are caused by the tensile force of the coil springs E3, E4, and E5. Returns to its original position and is locked to the engaging portions 91c, 92c, 93c. At this time, the tips of the head portions 916c, 917c, and 918c are inserted into the insertion holes 91d, 92d, and 93d of the attachment portions 91a, 92a, and 93a. When the front hook members 916, 917, and 918 return to their original positions, the front lock members 919, 920, and 921 also move upward to return to their original positions, and the upper pieces 919b, 920b, and 921b engage with the engaging portions 91c and 92c. , 93c are inserted into the insertion holes 91e, 92e, 93e. As a result, the locking is completed and the opening of the front frame set 14 is restricted, and the front lock members 919, 920, and 921 are locked (locked state).

  Further, in the present embodiment, when the cylinder lock 700 cannot be opened by operating the cylinder lock 700, such as when the cylinder lock 700 is broken, the inner flange members 913, 914 are attached from the back side of the pachinko machine 10. The inner frame 12 is opened by operating.

  When the inner frame 12 is in a locked state, the head 913c (914c) of the flange member 913 (914) is normally covered with a receiving metal fitting 830, as shown in FIG. Therefore, the inner collar member 913 (914) cannot be operated.

  Therefore, in order to operate, first, as shown in FIG. 48 (a), the breaking portion 830r is cut with a tool such as a nipper, and the lid portion 830t is separated from the main body portion of the metal fitting 830. By doing so, an opening 830x is formed in the receiving metal fitting 830, and the inner flange member 913 (914) can be operated through the opening 830x.

  More specifically, a rod-like tool G1 such as a flat-blade screwdriver is inserted into the receiving metal fitting 830 through the opening 830x. Then, as shown in FIG. 48B, the tool G1 is engaged with a notch 923k (924k) at the lower end of the lower piece 923c (924c) of the inner lock member 923 (924).

  Thereafter, as shown in FIG. 48 (c), the vertical edge portion of the notch 923k (924k) is pushed forward by the tool G1, and the lower piece 923c (924c) of the inner lock member 923 (924) is pushed forward. Then, the inner lock member 923 (924) is rotationally displaced against the tensile force of the coil spring E1 (E2), and the lower piece 923c (924c) is slightly retracted forward. If it will be in this state, it will be in the state which the lower piece part 923c (924c) pulled out from the lock hole part 830p of the metal fitting 830, and a locked state is cancelled | released. This direction in which the lower piece 923c (924c) of the inner lock member 923 (924) is pushed forward corresponds to the first direction in the present embodiment.

  With this state maintained, as shown in FIG. 48 (d), when the upper edge of the notch 923k (924k) is pushed upward by the tool G1, and the lock member 923 (924) is lifted upward, Without sliding the sliding rod 910, only the inner flange member 913 (914) and the inner lock member 923 (924) slide upward against the tensile force of the coil spring E1 (E2). This direction in which the inner flange member 913 (914) is pushed upward corresponds to the second direction in the present embodiment.

  When the inner flange member 913 (914) reaches the non-locking position, the engagement between the inner flange member 913 (914) and the metal fitting 830 is released, and the opening of the inner frame 12 is allowed.

  After the inner frame 12 is opened, the used metal fitting 830 is once removed from the outer frame 11, and a new metal fitting 830 is attached to the outer frame 11 again by the procedure described above.

  As described above in detail, in this embodiment, the inner lock members 923, 924 and the front lock members 919, 920, 921 are provided, so that the key K is not used when the inner frame 12 or the front frame set 14 is locked. When a direct unlocking operation, i.e., an unauthorized unlocking operation, is performed on the inner collar members 913, 914 and the front collar members 916, 917, 918 by wires or the like, the inner collar members 913, 914 or the front collar The sliding of the members 916, 917, and 918 in the unlocking direction is restricted. That is, since the inner flange members 913, 914 and the front flange members 916, 917, 918 are maintained at the locking positions, the inner frame 12 and the front frame set 14 are not allowed to be opened.

  On the other hand, when the unlocking operation is normally performed using the key K, the state of the inner lock members 923, 924 and the front lock members 919, 920, 921 is changed by receiving a force from the sliding rod 910, The inner collar members 913, 914 and the front collar members 916, 917, 918 can slide to the non-locking positions. That is, the inner flange members 913, 914 and the front flange members 916, 917, 918 are detached from the receiving bracket 830 and the receiving brackets 91, 92, 93, and the inner frame 12 and the front frame set 14 are allowed to be opened.

  The inner lock members 923, 924 and the front lock members 919, 920, 921 of the present embodiment are not configured to change state by contacting the outer frame 11 main body or the front frame set 14 main body. Therefore, there is no need to consider the contact position relationship between the inner lock members 923, 924 and the outer frame 11 body, the contact position relationship between the front lock members 919, 920, 921 and the front frame set 14 body, etc. For example, the front and rear lengths of the lower piece portion 923c and the like that are engaged with the receiving metal fitting 830 and the like of the inner lock member 923 and the like can be designed in advance so as to be longer with a margin. Even if a certain amount of play is provided between the frame 12 and the front frame set 14, the inner lock members 923, 924 and the front lock members 919, 920, 921 are more effective with respect to the brackets 830 and 91, 92, 93. It is easy to be securely locked. As a result, even if an assembling error between the inner frame 12 and the outer frame 11 or an assembling error between the inner frame 12 and the front frame set 14 becomes large, the inner lock members 923, 924 due to the assembling error Inconveniences such as functional deterioration of the front lock members 919, 920, 921 are reduced. In other words, larger manufacturing errors and assembly errors can be allowed, and the yield is improved.

  Further, even when the inner frame 12 or the front frame set 14 is forcibly pulled, the engagement between the inner lock members 923 and 924 and the receiving metal 830, or the front locking members 919, 920 and 921 and the receiving metal 91, 92 and 93. Is easily released and the inner frame 12 and the front frame set 14 are less likely to be released. Further, the inner lock members 923, 924 and the front lock members 919, 920, 921 do not slide the inner rod members 913, 914 or the front rod members 916, 917, 918 in the unlocking direction, not the sliding rod 910. Since the regulation is directly performed, unauthorized unlocking can be more reliably suppressed.

  Further, the inner lock members 923, 924 and the front lock members 919, 920, 921 are changed in state by using a wire or the like, and the inner flange members 913, 914 and the front flange members 916, 917, 918 are illegally unlocked. When trying to do so, the wire rods and the like hooked on the inner flange member 913 and the inner lock member 923 must be operated in at least two directions, so that it is difficult to perform an unauthorized unlocking operation.

  As a result, the defense performance against unauthorized unlocking using a wire or the like is significantly improved.

  Further, the inner lock members 923, 924 and the front lock members 919, 920, 921 are disposed between the corresponding inner flange members 913, 914, front flange members 916, 917, 918 and the sliding rod 910. By doing so, exposed portions of the inner lock member 923 and the like are reduced. Accordingly, the degree of exposure of a portion where a wire or the like can be hooked on the inner lock member 923 or the like, or a metal piece or the like can be pressed is also reduced, and it is difficult to perform the unauthorized unlocking operation as described above.

  Further, since the flange portion 903a is provided at the rear edge portion of the support plate 903, the wire rod or the like enters from the gap between the inner flange member 913 and the sliding rod 910, and is hooked on the inner lock member 923 or the like. Action becomes more difficult.

  In addition, the inner flange members 913, 914 are provided with guard portions 913f, 914f, and the front flange members 916, 917, 918 are provided with bulging recesses 916g, 917g, 918g functioning as guard portions. This makes it difficult to hook a wire or the like to the hook portions 923f and 924f of the inner lock members 923 and 924, the protrusion portions 923g and 924g, the protrusion portions 919g, 920g, and 921g of the front lock members 919, 920, and 921.

  As a result, the defense performance against unauthorized unlocking using a wire or the like can be further enhanced.

  In the present embodiment, the inner frame 12 and the front frame set 14 can be opened separately while sharing the sliding rod 910, thereby improving workability during maintenance and suppressing an increase in the number of parts. can do. In such a configuration, a configuration in which the inner flange members 913, 914 and the front flange members 916, 917, 918 are engaged with the sliding rod 910 so as to be movable up and down is unavoidable. , 914, etc., the defense function for preventing the inner collar members 913, 914, etc. from moving up and down is more effective.

  Further, since the inner flange members 913, 914 and the front flange members 916, 917, 918 are configured to slide and displace independently of each other, any one of the inner flange members 913, 914 is temporarily assumed by an illegal act, Alternatively, even if any of the front heel members 916, 917, 918 has been slid in the unlocking direction, the other does not slide, so the locked state of the inner frame 12 and the front frame set 14 is maintained, Opening is not allowed. As a result, the defense performance against unauthorized unlocking is further improved by a synergistic effect with the inner lock member 923 or the like that regulates the sliding displacement of the inner collar member 913 or the like in the unlocking direction.

  Moreover, in this embodiment, when locking the inner frame 12 and the front frame set 14, it is comprised so that locking can be performed without using the key K. FIG. More specifically, when locking the inner frame 12 or the like, the inner collar member 913 or the like comes into contact with the receiving metal fitting 830 or the like against the tensile force of the coil spring E1 or the like and is temporarily displaced in the unlocking direction. The lock member 923 or the like comes into contact with the metal fitting 830 or the like and is rotationally displaced. Thereafter, the inner flange member 913 and the like return to their original positions by the tensile force of the coil spring E1 and the like, and when locking is completed, the inner lock member 923 and the like also return to their original postures. As a result, opening of the inner frame 12 and the like is restricted, and a locked state is achieved in which the inner lock member 923 and the like are locked. With such a configuration, the inner frame 12 and the like can be closed smoothly without the inner lock member 923 and the like being in the way, and workability is improved.

  In addition, in this embodiment, since the flange members 913, 914 and the inner lock members 923, 924 are covered by the receiving metal fittings 830, it is difficult to hook a wire or the like on the flange members 913, 914 or the inner lock members 923, 924. Become. As a result, it is possible to prevent a direct unlocking operation with respect to the flange members 913 and 914 using a wire or the like, that is, an unauthorized unlocking operation.

  Furthermore, for a valid reason such as when the cylinder lock 700 is broken, the hook member 913, 914 must be operated from the back side of the pachinko machine 10 without using the key K, and the engaged state must be released. In this case, similarly to the first embodiment, the lid 830t can be separated from the main body of the metal fitting 830, and the work can be performed through the opening 830x formed there. That is, it is possible to more surely prevent fraud without disturbing the efficiency of work performed for a valid reason.

  In addition, when the lid portion 830t is separated, the trace remains on the metal fitting 830. Therefore, in the unlikely event that an illegal act is performed by opening the lid 830t, it is possible to detect the illegal act 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.

  Further, when the receiving metal fitting 830 is fixed to the outer frame 11, the receiving metal fitting 830 cannot be removed. Generally, after the pachinko machine 10 is installed in the island facility of the game hall, other pachinko machines 10 and the like are arranged adjacent to each other, so the screw 799 is attached from the outside of the right side frame constituting portion 11d of the outer frame 11. Cannot be removed. Therefore, in order to remove the catch 830 without being damaged, it is necessary to remove the pachinko machine 10 from the island facility once, and it is difficult to perform an illegal act without leaving a trace.

  As a result, the protection performance against unauthorized unlocking is greatly improved while improving maintainability.

  Further, in the present embodiment, the main body portion of the metal fitting 830 and the lid portion 830t are integrally formed of a metal material. As a result, it becomes more difficult to separate the lid portion 830t, and when the lid portion 830t is separated, the trace remains reliably, so that the defense performance against unauthorized unlocking can be further enhanced. Furthermore, it is harder to break than a shielding member made of a resin material. Moreover, the process of providing the cover part 830t can be omitted separately, and an increase in the number of parts can be suppressed.

  In addition, as compared with the configuration in which the metal bracket 83 and the resin resin cover 801 are separated as in the first embodiment, the assembly work of both can be omitted, and the assembly process In addition to simplification, there is no concern that only the resin cover 801 will be removed due to fraud.

  In addition, in the present embodiment, a notch 923k (924k) capable of engaging a tool G1 such as a flat-blade screwdriver is provided at the lower end of the lower piece 923c (924c) of the inner lock member 923 (924). Yes. Then, in a state where the tool G1 is engaged with the inner lock member 923 (924) inside the receiving metal fitting 830 from the outside via the opening 830x, the tool G1 is operated to operate the inner lock member 923 (924). ) And the inner collar member 913 (914) can be unlocked. Accordingly, even if the size of the opening 830x is set to be relatively small in order to prevent fraud, the inner lock member 923 (924) and the inner collar member 913 (914) can be relatively easily moved from the outside of the metal fitting 830. Unlocking operation can be performed.

  Further, when performing the above-described operation using the tool G1, the lower piece of the inner lock member 923 (924) is operated by operating the tool G1 engaged with the notch 923k (924k) of the inner lock member 923 (924). The part 923c (924c) is pushed forward, the tool G1 is operated upward while releasing the locked state of the inner lock member 923 (924), and the inner collar member 913 (914) is interposed via the inner lock member 923 (924). It is configured to release the engagement between the inner collar member 913 (914) and the receiving metal fitting 830 by an operation such as lifting the upper edge. In other words, in the case of an unauthorized unlocking operation, at least two wires for operating the inner lock member 923 (924) and the inner collar member 913 (914) are required, but in the case of a regular unlocking operation with the tool G1 In other words, both the inner lock member 923 (924) and the inner collar member 913 (914) can be operated simultaneously with one tool G1. Thereby, while maintaining the difficulty with respect to the unauthorized unlocking operation of the inner lock member 923 (924) and the inner collar member 913 (914) using a wire or the like, the regular inner lock member via the tool G1 is maintained. The unlocking operation of 923 (924) and the inner collar member 913 (914) can be performed relatively easily.

  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.

  (B) The configuration of the cylinder lock 700 is not limited to the above embodiment. For example, a cylinder lock that can change the key code may be employed. An example of a key code changing procedure will be described. After a predetermined reset pin is pressed and the current key is inserted into the keyhole and rotated, the key is pulled out. Then, while holding down the reset pin, a key to be newly set is inserted into the key hole, and the key is pulled out after releasing the pressed state of the reset pin after rotating in the opposite direction to the current key. By performing the operation as described above, a key code suitable for a new key to be set can be obtained.

  In the above embodiment, the cylinder lock 700 is locked when the key K is not inserted, and the sliding displacement of the sliding rod 610 is regulated by the cam plate 720. For example, when the sliding rod 610 is at the reference position, both the engaging claws 720a and 720b of the cam plate 720 are not inserted into the engaging holes 725 and 726. A configuration in which sliding of 610 is not restricted may be employed. A cylinder lock that does not lock even when the key K is not inserted (the cam plate 720 cannot be displaced) may be employed. In such a case, the inner frame 12 is opened as described above even if the inner flange members 613, 614, etc. are formed integrally with the sliding rod 610 so that they cannot be displaced relative to the sliding rod 610. When the situation becomes impossible, there is no inconvenience in operating the inner flange members 613 and 614 to open the inner frame 12 directly from the back side of the pachinko machine 10.

  (C) The configuration of the inner collar members 613, 614 and the front collar members 616, 617, 618 is not limited to the above embodiment. For example, in the above-described embodiment, the inner flange member 613 and the like are configured to slide in the vertical direction. However, the configuration is not limited thereto, and the inner flange member 613 and the like are rotationally displaced between the locking position and the non-locking position. You may employ | adopt the structure to do.

  Further, the number of hook members such as the inner hook member 613 and the members to be engaged such as the receiving metal fitting 83 corresponding thereto is not limited to the number of the above embodiments, and the locking of the inner frame 12 is not limited. For example, there may be one corresponding to each locking mechanism such as a mechanism.

  Moreover, in the said embodiment, although the resin cover 801 is attached to the receiving metal fitting 83 corresponding to the both collar members of the collar members 613 and 614, the resin cover 801 was provided corresponding to only one collar member. The same function and effect can be obtained sufficiently as a configuration.

  (D) The configuration of the resin cover 801 is not limited to the above embodiment. The formation position, size, range, and the like of the lid 801q can be changed as appropriate.

  For example, in the above-described embodiment, the lid 801q is completely separated from the main body of the resin cover 801. However, the present invention is not limited to this, and a part of the lid 801q remains connected to the main body. The opening 801s may be formed.

  Moreover, in the said embodiment, although the cover part 801q is integrally formed in the main-body part of the resin cover 801 beforehand as a resin molded object, it does not restrict to this but is separately molded by the opening part 801s of the resin cover 801. The lid portion 801q may be attached by a fixing means such as an adhesive.

  In the above-described embodiment, the lid portion 801q can be separated from the main body portion of the resin cover 801 by providing a plurality of slits 801p. However, the present invention is not limited thereto, and a thin wall is formed around the entire lid portion 801q. It is good also as a structure which can be cut | disconnected from the main-body part of the resin cover 801 by providing a part. In this way, normally, since the gap into which the wire or the like enters is not formed inside the resin cover 801, the defense performance can be improved.

  (E) In the above embodiment, the engaged member to which the flange members 613 and 614 are engaged and the shielding member (first cover member) surrounding the periphery are integrally formed as the receiving metal fitting 83. ing. However, the present invention is not limited thereto, and these may be provided separately.

  (F) In the above embodiment, the metal receiving metal fitting 83 constituting the first cover member and the resin resin cover 801 as the second cover member are separately configured as the shielding member. The shape, material, assembly structure, and the like of the first cover member and the second cover member are not limited to the above embodiment. For example, as in the second embodiment, the first cover member and the second cover member may be integrally formed of a resin material, a metal material, or the like as the shielding member.

  Moreover, when integrally forming with a metal material, you may employ | adopt other structures, such as the structure shown not only in the said 2nd Embodiment but FIGS. 49 and 50, for example. The example shown in FIGS. 49 and 50 is different from the second embodiment in the configuration of the lid (opening).

  49, similarly to the second embodiment, a plurality of slits 830s are intermittently provided at the lower left portion of the rear wall portion 830f so as to surround a substantially rectangular range. However, in this configuration, the width of the connecting portion (breaking portion) 830r between the adjacent slits 830s is set to be relatively wide as compared to the second embodiment. For this reason, when cutting the connecting portion 830r and separating the lid portion 830t from the main body portion, a saw for metal cutting or the like is used instead of a nipper or the like. In this way, the lid portion 830t cannot be easily separated from the main body portion, and at the normal time, it is possible to reduce a gap for illegally entering a wire rod or the like inside the metal fitting 830, so that the defense performance is improved. Can be increased.

  50 has a configuration in which a vertically long lid 840 is connected to the main body at two upper and lower positions. The upper connecting portion 841 is set narrower than the lid portion 840 main body. Although the left and right side edge portions of the lid portion 840 are separated from the metal fitting 830, the lid portion 840 is usually in a substantially abutting state so that no gap is formed so that a wire or the like can enter. Yes.

  And when opening the cover part 840, first, as shown to Fig.51 (a), the upper connection part 841 is cut | disconnected by a nipper etc. As shown in FIG. Thereafter, as shown in FIG. 51 (b), a tool G 1 such as a flat-blade screwdriver is inserted into the gap between the main body portion of the receiving metal fitting 830 and the upper end portion of the lid portion 840. Subsequently, as shown in FIG. 51 (c), with the lower connecting portion 842 being connected to the main body portion, the lid portion 840 is tilted backward with the connecting portion 842 as a base point, thereby opening the opening. Part 845 is formed. In this way, similarly to the above, the lid portion 840 cannot be easily opened, and the gap for allowing the wire rod or the like to be illegally entered inside the receiving metal fitting 830 can be reduced in the normal state. Can be increased.

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

  (H) The configuration of each of the inner locking members 923, 924 and the front locking members 919, 920, 921 is not limited to the second embodiment. For example, in the second embodiment, the inner lock members 923, 924 and the front lock members 919, 920, 921 are rotationally displaced to be in a locked state (first state) and an unlocked state (second state). The state changes. For example, a lock member that slides in a substantially horizontal direction in conjunction with the operation of the sliding rod 910 by a rack and pinion mechanism may be employed.

  In the second embodiment, the inner lock members 923, 924 and the front lock members 919, 920, 921 are replaced with the corresponding inner flange members 913, 914, front flange members 916, 917, 918, and sliding rods. 910. However, the configuration is not limited thereto, and the inner lock member 923 and the like may be disposed on the side opposite to the sliding rod 910 with respect to the inner flange member 913 and the like.

  In addition, instead of the inner lock member 923 or the like that directly regulates the movement of the inner flange member 913 or the like, by restricting the movement of the sliding rod 910 when the inner frame 12 is closed, the flange member such as the inner flange member 913 or the like It is good also as a structure provided with the lock member which regulates a motion of this. For example, when the inner frame 12 is closed, the predetermined locking member is pushed and displaced by coming into contact with a predetermined part such as the outer frame 11 or the receiving metal fitting 830, and is slid by being inserted into a part of the sliding rod 910. An example is a configuration that engages with the collar 910 and restricts the movement of the sliding collar 910 and thus the inner collar member 913 and the like.

  (I) In the second embodiment, in order to make the inner lock members 923 and 924 easy to operate, a notch portion capable of engaging a tool G1 such as a screwdriver as a tool engaging portion with the inner lock members 923 and 924. 923k and 924k are provided. Instead of this, as the tool engaging portion, for example, a configuration may be adopted in which protrusions are provided on the side surfaces of the inner lock members 923 and 924. Moreover, it is good also as a structure which abbreviate | omitted the tool engaging part.

  Further, not only the inner lock members 923 and 924 but also the inner collar members 913 and 914 may be provided with a tool engaging portion.

  Furthermore, in the said 2nd Embodiment, the tool G1 is inserted from the back side of the receiving metal fitting 830, the said tool G1 is operated, and the lower piece part 923c (924c) of the inner lock member 923 (924) is 1st direction. The operation in two directions, such as pushing the tool forward, and releasing the locked state of the inner lock member 923 (924), operating the tool G1 upward in the second direction, and lifting the inner collar member 913 (914). Thus, the engagement between the inner flange member 913 (914) and the metal fitting 830 is released.

  Not limited to this, both the inner collar member 913 (914) and the inner lock member 923 (924) may be released by operating the tool G1 in one direction. For example, the tool G1 can be inserted from the lower side of the metal fitting 830, and the inner hook member 913 (914) is moved forward while pushing the lower piece portion 923c (924c) of the inner lock member 923 (924) with the tool G1. ) May be pushed upward to disengage the inner flange member 913 (914) from the receiving metal fitting 830.

  (J) In the second embodiment, regarding the locking mechanism of the inner frame 12, inner locking members 923 and 924 are provided corresponding to both inner flange members 913 and 914, and regarding the locking mechanism of the front frame set 14, The front lock members 919, 920, and 921 are provided so as to correspond to all the three forehead members 916, 917, and 918. For example, the locking mechanism of the inner frame 12 may be configured to include an inner lock member corresponding to only one of the two inner collar members 913 and 914. In addition, regarding the locking mechanism of the front frame set 14, a front lock member may be provided corresponding to at least one of the three front heel members 916, 917, and 918. If it is provided corresponding to at least one, the defense performance against unauthorized unlocking can be sufficiently exhibited.

  (K) In the second embodiment, for example, the urging force of the coil springs E1 and E2 is transmitted to the inner flange members 913 and 914 via the inner lock members 923 and 924, for example. That is, the urging means for the inner flange members 913 and 914 and the maintaining means for the inner lock members 923 and 924 are constituted by a single coil spring E1 and E2. Similarly, the urging means for the front saddle members 916, 917, and 918 and the maintaining means for the front lock members 919, 920, and 921 are configured by a single coil spring E3, E4, and E5. However, the present invention is not limited to this, and the biasing means of each flange member and the maintaining means of each lock member may be constituted by separate coil springs. Of course, the biasing means and the maintaining means are not limited to coil springs. Moreover, it is good also as a structure which the force of an urging | biasing means and a maintenance means is transmitted to a collar member or a lock member indirectly via other members, such as the sliding rod 910.

  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 fixed frame constituting the outer shell,
A door body that can be opened and closed on the front side of the fixed frame;
A locking device provided on the door body and locking the door body with respect to the fixed frame;
The locking device is
A locking member operated by a key;
In conjunction with at least the operation of the lock member in accordance with the operation of the key, an engagement position that is engaged with an engaged member provided on the fixed frame and restricts the opening of the door body; In a gaming machine comprising a gutter member disengaged from an engagement member and displaceable to a non-engagement position allowing the opening of the door body,
A shielding member surrounding the engaged member and the flange member engaged with the engaged member;
A gaming machine characterized in that an opening can be formed in the shielding member by providing a part of the shielding member that can be separated or opened.

  According to the said means 1, it becomes difficult to hook a wire etc. with respect to the collar member engaged with a to-be-engaged member by providing a shielding member. As a result, it is possible to prevent a direct unlocking operation, i.e., an unauthorized unlocking operation, with respect to the eaves member using a wire or the like.

  Furthermore, by providing the above-mentioned lid portion, for a valid reason such as when the lock member fails, the hook member is directly operated from the back side of the gaming machine without using a key to release the engaged state with the engaged member. When the situation becomes indispensable, the cover part of the shielding member can be cut or opened, and the work can be performed through the opening formed there. That is, it is possible to more surely prevent fraud without disturbing the efficiency of work performed for a valid reason.

  In addition, when the lid is separated, the trace remains on the shielding member. Therefore, in the unlikely event that a fraudulent act is performed with the lid open, the fraud 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.

  As a result, the protection performance against unauthorized unlocking is significantly improved as compared with the case where the entire shielding member can be moved while improving the maintainability.

  Note that the number of hook members and the members to be engaged corresponding thereto is not limited to one, and a plurality of these members may be provided (a shielding member corresponding to them, a lock member shown below, etc.) The same applies to). In this way, the defense performance against unauthorized unlocking can be further improved.

  In addition, the above “separation” means that the lid is removed from the main body of the shielding member (cutting), and “cut open” means that a part of the lid is connected to the main body of the shielding member. This means that the opening is formed in the state (including removal of a separate lid fixed to the main body of the shielding member).

  Examples of the lock member include a cylinder lock that is rotated by inserting a key. Of course, the lock member is not limited to the cylinder lock, but may be operated using a key such as a card key.

  In addition, the “engagement (engaged state)” of the eaves member and the engaged member refers to the eaves member when the door body is moved in at least the direction of opening the door body (for example, the front direction). And the to-be-engaged member contacts and the state which exists in the positional relationship which regulates opening of a door body is pointed out. Therefore, in the “engagement” of the flange member and the engaged member, not only when they are always in contact but also with a predetermined clearance (play) between them in consideration of operability and the like, In the closed state of the door body, the case where both are separated is included. For example, with respect to the front-rear direction, which is the opening / closing direction of the door body, a predetermined clearance is set between the engagement member and the engaged member, and in the closed state of the door body, the engagement member and the engaged member Although the member is not in contact with the front-rear direction, when the member is moved to open the door body, it is only necessary that the members are engaged with each other. Conversely, “non-engagement (non-engaged state)” between the eaves member and the engaged member is a positional relationship where the eaves member and the engaged member do not contact when the door body is moved in the opening and closing direction, or The state which exists in the positional relationship which can open | release a door body, contacting.

  Mean 2. The shielding member includes a metal first cover member fixed to the fixing frame by a predetermined fixing means, and a resin second cover member assembled to the first cover member and having the lid portion. The gaming machine according to means 1, wherein the gaming machine is configured.

  According to the above means 2, by configuring the portion excluding the second cover member having the lid portion with the first cover member made of metal, it is possible to ensure sufficient protection performance against unauthorized unlocking. Further, even when the lid is used after being separated, it is possible to restore the original state only by replacing the used second cover member only with a new unused second cover member. Therefore, it is not necessary to replace the entire shielding member, and the recyclability is excellent.

  Means 3. The gaming machine according to claim 2, wherein the second cover member cannot be removed from the first cover member at least in a state in which the first cover member is attached to the fixed frame.

  According to the means 3, it is possible to further enhance the effect of suppressing the above-described fraud. Note that the phrase “the second cover member cannot be removed” means that the second cover member cannot be removed or is extremely difficult unless the first cover member is removed from the fixed frame. For example, in a configuration in which the locking piece provided on the second cover member is locked to the first cover member so that both are assembled, the first cover member is attached to the fixed frame. At least one locking piece of the second cover member locked to the cover is not exposed to the outside of the first cover member by being covered with the fixed frame, and the unlocking operation is performed from the outside of the first cover member. An example is a configuration that cannot be performed.

  Means 4. The gaming machine according to claim 2 or 3, wherein the lid portion is integrally formed with the main body portion of the second cover member via a severable connecting portion.

  According to the above means 4, it is possible to omit the step of separately providing a lid, and to suppress an increase in the number of parts.

  Means 6. The gaming machine according to any one of means 1 to 5, wherein the engaged member and the shielding member are integrated.

  According to the means 6, the engaged member and the shielding member are integrated, so that the number of parts can be reduced and the configuration can be simplified.

  Mean 7 The gaming machine according to means 1, wherein the main body portion and the lid portion of the shielding member are integrally formed of a metal material.

  According to the means 7, when the main body portion and the lid portion of the shielding member are integrally formed of a metal material, it becomes more difficult to separate the lid portion, and when the lid portion is separated, etc. Since the trace remains reliably, the defense performance against unauthorized unlocking can be further enhanced. Moreover, the process of providing a cover part can be omitted separately, and the increase in a number of parts can be suppressed.

  Means 8. The gaming machine according to claim 7, wherein the engaged member and the shielding member are integrated.

  According to the means 8, the same effect as that of the means 6 is obtained.

Means 9. The locking device is

  According to the means 9, by providing the lock member, when the door is closed, a direct unlocking operation, i.e., an unauthorized unlocking operation, is performed on the eaves member with a wire or the like without using a key. In that case, the movement of the eaves member in the unlocking direction is restricted. That is, since the eaves member is maintained in the engaged position, the door body is not allowed to open.

  In addition, if the lock member is changed in its state by using a wire or the like, and if the lock member is illegally unlocked, the wire or the like hooked on the lock member and the lock member is operated in at least two directions. This makes it difficult to perform unauthorized unlocking operations. As a result, the defense performance against unauthorized unlocking using a wire or the like is significantly improved.

  Moreover, by providing the said shielding member, while it becomes difficult to hook a wire etc. with respect to the collar member engaged with a to-be-engaged member, it becomes difficult to hook a wire etc. also with respect to a lock member. As a result, the defense performance against unauthorized unlocking can be further improved. In other words, for a valid reason such as when the lock member is broken, it is necessary to release the engaged state with the engaged member by directly operating the saddle member from the back side of the gaming machine without using a key. In this case, the lid portion of the shielding member can be cut or opened, and the operation can be performed by operating the eave member while releasing the lock member via the opening formed there. That is, it is possible to more surely prevent fraud without disturbing the efficiency of work performed for a valid reason.
