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 so as to be openable and closable with respect to a fixed frame (outer frame), and a locking device is provided so that the gaming machine main body cannot be opened. As such a locking device, there is known a device provided with a cylinder lock operated using a key and a hook member provided so as to be able to be engaged with and disengaged from an engaged member provided on a fixed frame. In the locked state, the gaming machine main body cannot be opened with respect to the fixed frame by the hook member engaging the corresponding engaged member. On the other hand, when the cylinder lock is unlocked with the key, the hook member is detached from the engaged member, and the gaming machine main body can be opened.

  In recent years, in gaming halls, there are cases where fraudulent acts to illegally unlock gaming machine bodies. Such unauthorized unlocking is performed by inserting a wire such as a wire and hooking the wire on the hook member of the locking device and moving it in the unlocking direction.

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

  As described above, generally, in gaming machines such as pachinko machines, the gaming machine main body (inner frame) is provided to be openable and closable with respect to the 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 including a protective cover surrounding an engaged member and a hook member engaged therewith has also 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.

  For this reason, generally, as in the invention described in Japanese Patent Application Laid-Open No. 2001-224812, the protective cover is fixed to the fixed frame (outer frame) with screws or the like so that it can be easily removed.

  However, if it can be easily removed in this way, the defense performance against unauthorized unlocking may be 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.

Due to the tensile force of the coil springs C3, C4, and C5, the front end side of the front lock members 619, 620, and 621 is normally pulled upward and forward, and the front lock members 619, 620, and 621 themselves as well as the above. The forehead members 616, 617, and 618 are biased upward via the guide pins 651 to 653, the guide pins 657 to 659, the hook portions 619f, 620f, and 621f. 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. Further, in this state, the front lock members 619, 620, 621 are in a state where the lower edge portions of the guide holes 619e, 620e, 621e are in contact with the guide pins 651, 652, 653, and the reference posture as shown in FIG. Take.

  In addition, protrusions 619g, 620g, and 621g protruding rearward are formed on the rear side of the lower end portions of the vertical piece portions 619a, 620a, and 621a of the front lock members 619, 620, and 621. Correspondingly, rear action pieces 610d, 610e, and 610f that are bent outward from the inner frame 12 are formed at the rear edge of the sliding rod 610. The rear action pieces 610d, 610e, and 610f of the sliding rod 610 can come into contact with the protrusions 619g, 620g, and 621g of the front lock members 619, 620, and 621. Further, corresponding to the positions where these protrusions 619g, 620g, 621g and the rear action pieces 610d, 610e, 610f are formed, the rear edge portions of the base portions 616a, 617a, 618a of the front rod members 616, 617, 618 are The bulging recessed parts 616g, 617g, and 618g which bulged to the outer side of the inner frame 12 are formed. Thereby, the operation | movement of the back action pieces 610d, 610e, and 610f of the sliding rod 610 is not prevented. The bulging recesses 616g, 617g, and 618g have a function as a guard part, and prevent the entry of the wire material or the like from the outside to the protrusions 619g, 620g, 621g side of the front lock members 619, 620, 621. In contrast, it makes it difficult to hook the wire.

  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 engagement position (reference position) of the front heel members 616, 617, and 618.

  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 disengagement position of the front heel members 616, 617, and 618.

  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). ).

  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 619, 620, and 621, respectively. , 617, 618 are engaged with the metal fittings 91, 92, 93, the upper pieces 619b, 620b, 621b of the front lock members 619, 620, 621 are inserted into the insertion holes 91e, 92e, 93e. A state is reached (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. And when the cylinder lock 700 mentioned later is operated, it slides and displaces upward or downward against the tensile force of coil spring C1 grade | etc.,.

  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 as an engaging member that transmits the rotation operation 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.

  Under the above configuration, when the lock shaft 703 and the cam plate 720 are at the reference position in a state where the key K is not inserted into the key hole 702 of the cylinder lock 700, as shown in FIG. The distal end of 720a is inserted into the upper engaging hole 725 of the sliding rod 610, and the distal end of the lower engaging claw 720b is inserted into the lower engaging 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 FIGS. 22 and 24). In a state where the inner flange members 613 and 614 are engaged with the respective receiving fittings 83, the lower pieces 615c and 623c of the inner lock members 615 and 623 are inserted into the lock holes 83p (see FIG. 22). ). However, in FIG. 22, for convenience, a partial cross-sectional view with the resin cover 801 removed is shown.

  Temporarily, when the inner frame 12 is in the open state, a wire rod or the like is hooked on the protrusion 613b (614b) or the head 613c (614c) of the inner collar member 613 (614) in the locking position, and the sliding collar 610 is interposed therebetween. First, when an external force in the unlocking direction (upward) is applied to the inner flange member 613 (614), the inner flange member 613 (614) slides upward as shown in FIG. The inner lock member 615 (623) slides upward. At this time, since the inner lock member 615 (623) is attracted to the mounting plate 602 side (forward and downward) by the tensile force of the coil spring C1 (C2), it slides upward while maintaining the normal reference posture. . The state in which this reference posture is maintained corresponds to the first state of the inner lock member 615 (623) in the present embodiment.

  Therefore, 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 613 (614) in the locking position without using the key K. In this case, the lower piece 615c (623c) of the inner lock member 615 (623) is hooked on the front wall 83a of the receiving fitting 83. That is, even if the inner collar member 613 (614) is slid in the unlocking direction, its movement is substantially restricted except for play such as the lock hole 83p. Of course, the play amount of the lock hole portion 83p is such that the inner hook member 613 (614) has a play amount even when the lower piece 615c (623c) of the inner lock member 615 (623) is in contact with the front wall portion 83a of the metal fitting 83. The head 613 c (614 c) is set so as not to be detached from the receiving metal fitting 83. As a result, the inner flange member 613 (614) 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 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, as shown in FIG. 26 (a), first, the front action piece 610b (610c) of the sliding rod 610 is moved into the protrusion 615g (623g) of the inner lock member 615 (623). And push it upward. Then, the inner lock member 615 (623) is rotationally displaced against the tensile force of the coil spring C1 (C2), and the lower piece 615c (623c) is slightly retracted forward (on the mounting plate 602 side). It becomes. This state corresponds to the second state of the inner lock member 615 (623) in the present embodiment. If it will be in this state, it will be in the state which the lower piece part 615c (623c) pulled out from the lock hole 83p of the metal fitting 83, and a locked state will be cancelled | released.

  Further, when the sliding rod 610 slides upward, the guide pin 631 (632) is pulled up by the lower edge portion of the inner guide hole 625 (626) of the sliding rod 610, and as shown in FIG. The inner flange member 613 (614) slides upward against the tensile force of the coil spring C1 (C2). At this time, the inner lock member 615 (623) slides upward together with the inner collar member 613 (614). Thereby, the engagement between the inner flange member 613 (614) and the metal fitting 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), the lower part of the inner guide holes 645, 646, and 647 of the sliding collar 610 engaged with the guide pins 651, 652, and 653 , Guide pins 651, 652, 653, and rear action pieces are disposed on the upper portions of the bulging recesses 616 g, 617 g, 618 g of the front collar members 616, 617, 618 into which the rear action pieces 610 d, 610 e, 610 f are inserted. Spaces for relative displacement of 610d, 610e, and 610f are secured. 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. At this time, the inner lock members 615 and 623 are rotationally displaced in contact with the front wall portion 83a. 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. When the inner flange members 613 and 614 return to their original positions, the inner lock members 615 and 623 also move downward and return to their original positions, and the lower piece portions 615c and 623c are inserted into the lock hole portion 83p. As a result, the locking is completed, the opening of the inner frame 12 is restricted, and the inner locking members 615 and 623 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 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, 618c of the front saddle members 616, 617, 618 are locked, and the opening of the front frame set 14 is restricted (see FIGS. 23, 24). 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. The upper piece portions 619b, 620b, 621b of the front lock members 619, 620, 621 are inserted into the insertion holes 91e, 92e, 93e of the engaging portions 91c, 92c, 93c. A state is reached (see FIG. 23).

  Temporarily, in the open state of the front frame set 14, a wire or the like is hooked on the protrusion 616b (617b, 618b) or the head 616c (617c, 618c) of the front heel member 616 (617, 618) in the locking position. When the external force in the unlocking direction (downward) is applied to the front collar member 616 (617, 618) without the sliding collar 610, the front collar member 616 (617, 618) is moved as shown in FIG. While sliding downward, the front lock member 619 (620, 621) slides downward in conjunction with this. At this time, the front lock member 619 (620, 621) is attracted to the mounting plate 602 side (forward and upward) by the tensile force of the coil spring C3 (C4, C5). 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, for example, by hooking a wire rod or the like to the forward member 616 (617, 618) in the locking position. When the operation is performed, the upper piece 619b (620b, 621b) of the front lock member 619 (620, 621) is inserted into the insertion hole 91e of the engaging portion 91c (92c, 93c) of the receiving metal fitting 91 (92, 93). (92e, 93e) will be caught on the lower edge. That is, even if the front heel member 616 (617, 618) 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 619b (620b, 621b) of the front lock member 619 (620, 621) is inserted into the insertion hole 91e (92e) of the engagement portion 91c (92c, 93c). , 93e) is set such that the head 616c (617c, 618c) of the forward saddle member 616 (617, 618) does not detach from the catch 91 (92, 93) even in the state where it abuts against the lower edge portion. . As a result, the front saddle member 616 (617, 618) 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 in FIG. As a result, as shown in FIGS. 21A and 21B, the cam plate 720 rotates in the same direction, and the upper engagement claw 720 a moves 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, as shown in FIG. 28 (a), first, the rear action piece 610d (610e, 610f) of the sliding rod 610 is the projection of the front lock member 619 (620, 621). Contact 619g (620g, 621g) and push it down. Then, the front lock member 619 (620, 621) is rotationally displaced against the tensile force of the coil spring C3 (C4, C5), and the upper piece portion 619b (620b, 621b) is rearward (on the flange portion 603a side). ) Slightly retracted. In this state, the upper piece 619b (620b, 621b) 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 610 slides downward, as shown in FIG. 28 (b), the guide pin 651 (652, 653) is formed by the upper edge portion of the inner guide hole 645 (646, 647) of the sliding rod 610. Is pulled down, and the forehead member 616 (617, 618) slides downward against the tensile force of the coil spring C3 (C4, C5). At this time, the front lock member 619 (620, 621) slides downward together with the front collar member 616 (617, 618). As a result, the engagement between the front saddle member 616 (617, 618) and the catch 91 (92, 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 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, or the sliding rod 610 Spaces for relative displacement of the guide pins 631 and 632 and the front action pieces 610b and 610c are secured below the notch recesses 613d and 614d of the inner flange members 613 and 614 into which the front action pieces 610b and 610c are inserted. 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. At this time, the front lock members 619, 620, and 621 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 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. When the front saddle members 616, 617, and 618 return to their original positions, the front lock members 619, 620, and 621 also move upward to return to their original positions, and the upper pieces 619b, 620b, and 621b 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, the opening of the front frame set 14 is restricted, and the front lock members 619, 620, 621 are locked (locked state).

  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 engagement between 614 and the receiving metal fitting 83 is released, and the inner frame 12 is opened.

  When the inner frame 12 is in a locked state, normally, as shown in FIG. 24, the head 613c (614c) of the flange member 613 (614) is covered with the receiving metal 83 and the resin cover 801. Therefore, the inner collar member 613 (614) cannot be directly operated.

  Therefore, in order to release the engagement between the inner flange members 613 and 614 and the metal fitting 83, at least the resin cover 801 must be removed. For that purpose, first, each covering wall part 801b will be excised. Hereinafter, the operation process will be described by taking the upper covering wall portion 801b as an example, but the lower covering wall portion 801b is similarly performed.

  As shown in FIGS. 35 (a) and 36 (a), the tip of a tool G1 such as a flat-blade screwdriver is inserted into the gap between the covering wall portion 801b of the resin cover 801 and the protruding wall portion 90 from obliquely below. .

  Subsequently, as shown in FIGS. 35 (b) and 36 (b), the handle of the tool G1 is pushed upward while the tip of the tool G1 is supported by the protruding wall 90. Thereby, the some fracture | rupture part 801r is cut | disconnected sequentially from lower side, and the coating | coated wall part 801b is cut away from the vertical wall part 801a.

  As described above, since the covering wall portion 801b is chamfered on the upper side of the side wall portion 801h, the above operation can be performed relatively smoothly. On the other hand, if the tool G1 is inserted into the gap between the covering wall portion 801b and the protruding wall portion 90 from the upper side and the same operation is attempted, the lower side of the side wall portion 801h that is not chamfered is caught. Great power is required. Furthermore, there is a possibility that the covering wall portion 801b cannot be appropriately excised, such as breaking at a portion different from the breaking portion 801r. Further, even if the lower side of the side wall 801h is chamfered, the locking claw of the locking piece 801g locked in the locking hole 83m of the metal fitting 83 does not come out, so that the same problem as described above occurs. Can occur. Therefore, under the configuration of this embodiment, the tool G1 is inserted into the upper covering wall portion 801b from the lower side, and the tool G1 is inserted into the lower covering wall portion 801b from the upper side. It is preferable to insert the

  As shown in FIGS. 35 (c) and 36 (c), when the covering wall portion 801 b is completely separated, the head portion 799 a of the screw 799 fixing the receiving metal fitting 83 is exposed. Thereby, a predetermined tool (such as a Phillips screwdriver) can be engaged with the tool engaging portion (cross groove) of the head 799a of the screw 799.

  Then, as shown in FIG. 36 (d), by removing the screw 799 and removing the receiving fitting 83, the engagement between the inner flange member 613 (614) and the receiving fitting 83 is released. The opening of the inner frame 12 is allowed without operating 613 (614).

  After the inner frame 12 is opened, the receiving metal fitting 83 is attached again in the above-described procedure, and a new resin cover 801 is attached instead of the used resin cover 801 to return to the original state.

  A method of cutting the broken portions 801r one by one with a cutter, a nipper, or the like is also conceivable. However, when the number of the broken portions 801r is large as in the present embodiment, it is very troublesome. Moreover, since the fracture | rupture part 801r is arrange | positioned in the state which substantially contact | abutted to the edge part of the protrusion wall part 90, it is difficult to work. Therefore, the method described above is relatively simple and preferred.

  Of course, without being limited to the above method, the inner frame 12 can be opened without removing the metal fitting 83. That is, since the vertical wall portion 801a of the resin cover 801 can be removed by separating the covering wall portion 801b, a rod-shaped tool is inserted into the receiving metal fitting 83 from the gap where the vertical wall portion 801a is removed, The inner frame 12 may be opened by performing an unlocking operation of the eaves member 613 (614).

  More specifically, the lower piece 615c (623c) of the inner lock member 615 (623) is pushed forward by a rod-shaped tool inserted into the receiving metal fitting 83, and the lock by the inner lock member 615 (623) is released. The head 613c (614c) of the inner flange member 613 (614) is pushed upward, the engagement between the inner flange member 613 (614) and the receiving metal fitting 83 is released, and the inner frame 12 is opened. Good. However, the unlocking operation performed by inserting the tool through the slight gap in this way is not easy because an empirical element is necessary, and therefore the above-described method in which the metal fitting 83 is completely removed is more reliable and preferable.

  As described above in detail, in this embodiment, the inner lock members 615, 623 and the front lock members 619, 620, 621 are provided, so that the key K is not used when the inner frame 12 or the front frame set 14 is locked. When the inner hook members 613, 614 and the front hook members 616, 617, 618 are directly unlocked by a wire or the like, that is, when an unauthorized unlocking operation is performed, the inner hook members 613, 614 or the front hook The sliding of the members 616, 617, 618 in the unlocking direction is restricted. That is, since the inner flange members 613, 614 and the front flange members 616, 617, 618 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 inner lock members 615, 623 and the front lock members 619, 620, 621 change their states by receiving a force from the sliding rod 610, The inner collar members 613, 614 and the front collar members 616, 617, 618 can slide to the non-locking positions. That is, the inner flange members 613, 614 and the front flange members 616, 617, 618 are detached from the receiving metal 83 and the receiving metal 91, 92, 93, and the inner frame 12 and the front frame set 14 are allowed to be opened.

  The inner lock members 615, 623 and the front lock members 619, 620, 621 of the present embodiment are not configured to change state by abutting the outer frame 11 main body or the front frame set 14 main body. Therefore, it is not necessary to consider the contact position relationship between the inner lock members 615, 623 and the outer frame 11 body, the contact position relationship between the front lock members 619, 620, 621 and the front frame set 14 body, etc. For example, the front and rear lengths of the lower piece portion 615c and the like that engage with the metal fitting 83 and the like of the inner lock member 615 and the like can be designed to be longer with a margin in advance, between the inner frame 12 and the outer frame 11, Even if a certain amount of play is provided between the frame 12 and the front frame set 14, the inner lock members 615, 623 and the front lock members 619, 620, 621 are more effective than the metal fitting 83 and the metal fittings 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 615, 623 due to the assembling error, Inconveniences such as functional deterioration of the front lock members 619, 620, 621 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 615 and 623 and the receiving metal 83, the front lock members 619, 620 and 621 and the receiving metal 91, 92 and 93 are performed. 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 615, 623 and the front lock members 619, 620, 621 are not the sliding rods 610, but the inner rod members 613, 614 and the front rod members 616, 617, 618 slide in the unlocking direction. Since the regulation is directly performed, unauthorized unlocking can be more reliably suppressed.

  In addition, the inner lock members 615, 623 and the front lock members 619, 620, 621 are changed in state by using wires or the like, and the inner collar members 613, 614 and the front collar members 616, 617, 618 are illegally unlocked. In an attempt to do so, the wire rods and the like hooked on the inner flange member 613 and the inner lock member 615 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 615, 623 and the front lock members 619, 620, 621 are disposed between the corresponding inner flange members 613, 614 and front flange members 616, 617, 618 and the sliding rod 610. As a result, the exposed portions of the inner lock member 615 and the like are reduced. Accordingly, the degree of exposure of a portion where a wire rod or the like can be hooked on the inner lock member 615 or the like, or a metal piece or the like can be pressed is reduced, and the above-described unauthorized unlocking operation becomes difficult.

  Further, the flange portion 603a is provided at the rear edge portion of the support plate 603, so that the gap between the inner flange member 613 and the sliding rod 610 extends from the back side of the pachinko machine 10 beyond the protruding wall portion 90. Unauthorized acts such as entering a wire or the like and hooking it on the inner lock member 615 or the like become more difficult.

  In addition, the inner flange members 613 and 614 are provided with guard portions 613f and 614f, and the front flange members 616, 617 and 618 are provided with bulging recesses 616g, 617g and 618g which function as guard portions. This makes it difficult to hook a wire or the like to the hook portions 615f and 623f of the inner lock members 615 and 623, the protrusion portions 615g and 623g, the protrusion portions 619g, 620g, and 621g of the front lock members 619, 620, and 621.

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

  In the present embodiment, while the sliding rod 610 is shared, the inner frame 12 and the front frame set 14 can be opened separately, 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 613 and 614 and the front flange members 616, 617, and 618 are engaged with the sliding rod 610 so as to be movable up and down is unavoidable. , 614, etc., the defense function for preventing the inner collar members 613, 614, etc. from moving up and down is more effective.

  Furthermore, since the inner flange members 613, 614 and the front flange members 616, 617, 618 are configured to be slid and displaced independently of each other, any one of the inner flange members 613, 614 is temporarily assumed by an illegal act, Or, even if one of the front heel members 616, 617, 618 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 615 or the like that regulates the sliding displacement of the inner collar member 613 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 613 or the like comes into contact with the receiving metal 83 or the like against the tensile force of the coil spring C1 or the like and is temporarily displaced in the unlocking direction. The lock member 615 or the like comes into contact with the metal fitting 83 or the like and is rotationally displaced. Thereafter, the inner flange member 613 and the like return to their original positions by the tensile force of the coil spring C1 and the like, and when locking is completed, the inner lock member 615 and the like return to their original postures. As a result, the opening of the inner frame 12 and the like is restricted, and the locked state where the lock is applied by the inner lock member 615 and the like. With such a configuration, the inner frame 12 and the like can be closed smoothly without the inner lock member 615 and the like being in the way, and workability is improved.

  In addition, in the present embodiment, the flange members 613 and 614 and the inner lock members 615 and 623 are covered with the metal fitting 83 and the resin cover 801. For this reason, it becomes difficult to hook a wire etc. with respect to the eaves members 613 and 614 and the inner lock members 615 and 623. 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.

  Further, once the resin cover 801 is assembled, the metal fitting 83 cannot be removed regardless of whether the pachinko machine 10 is installed in the island facility of the game hall. Therefore, the defense performance against unauthorized unlocking is significantly improved as compared with the configuration in which the screws and the like for fixing the receiving metal fitting 83 are exposed and the receiving metal fitting 83 can be easily removed.

  On the other hand, 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, after the resin cover 801 is broken and removed, the engagement between the flange members 613 and 614 and the reception fitting 83 can be released by removing the reception fitting 83 or the like. That is, it is possible to more surely prevent fraud without disturbing the efficiency of work performed for a valid reason.

  Furthermore, when the resin cover 801 is removed by breaking it or the like, the trace remains there. Therefore, in the unlikely event that the resin cover 801 is destroyed and an illegal act is performed, the illegal act can be detected early by confirming it. Therefore, it is possible not only to prevent fraud directly but also to prevent fraud from the aspect of early detection of fraud.

  As a result, the protection performance against unauthorized unlocking is significantly improved as compared with the configuration in which the metal fitting 83 can be easily removed while improving the maintainability.

  Moreover, in this embodiment, since the left side frame structure part 11c and the right side frame structure part 11d are comprised by the extrusion molding material made from an aluminum alloy, while improving durability compared with the case where it is wooden, recyclability is good. improves. Moreover, since the left side frame constituting part 11c and the right side frame constituting part 11d are made of an extrusion molding material, it is not necessary to perform mold forming using a mold apparatus, so that the manufacturing process can be simplified.

  If the left side frame constituting part 11c and the right side frame constituting part 11d are made of metal, the thickness can be made relatively thin while maintaining the necessary strength. In this way, as in the pachinko machine 10, in the gaming machine whose outer shape is configured to be substantially the same shape as a standard, the space surrounded by the outer frame 11 is expanded in the left-right width direction, The space can be used more effectively.

  Furthermore, in the conventional wooden outer frame, router processing or the like has been applied to the frame components on both the left and right sides in order to expand the inner space in the left and right direction. Such work is not required, and the work process can be simplified.

  Conventionally, when installing a pachinko machine in a game hall, it is common to fix the wooden outer frame by hitting it with a nail or the like at the game machine installation location. Therefore, if the frame configuration portions 11a and 11b on both the upper and lower sides are made of a wooden plate material as in this embodiment, the pachinko machine 10 can be fixed with nails or the like as in the prior art, so that the game hall side is newly fixed. There is no need to prepare means, and the burden on the game hall side is reduced.

  As described above, the right side frame constituting portion 11d of the present embodiment is considerably thinner than the conventional wooden member. For this reason, there is a concern that the wire rod inserted from the side of the pachinko machine 10 is turned to the side of the locking device 600 through the back side of the outer frame 11 and the above-mentioned fraudulent action is easily performed.

  On the other hand, in this embodiment, the protruding wall portion 90 that covers the entire upper and lower sections corresponding to the locking device 600 from the back side of the inner frame 12 is formed in the right side frame constituting portion 11d. Thereby, it becomes more difficult to make a wire etc. approach from the back side of the outer frame 11, and to operate each eaves part, such as eaves member 613,614, by the said wire. As a result, the defense performance can be further improved.

  Furthermore, by forming the protruding wall portion 90, it is possible to suppress distortion, bending, and the like of the right side frame constituting portion 11d. As the strength of the right side frame constituting portion 11d increases as described above, the thickness can be further reduced, and the weight can be further reduced and the internal space can be further expanded. In addition, it becomes difficult to create a gap that allows the wire or the like to enter by bending the right side frame constituting portion 11d, and the defense performance against unauthorized unlocking can be further improved.

  As a result, the defense performance against unauthorized unlocking using a wire or the like can be enhanced while the thicknesses of the left side frame constituting part 11c and the right side frame constituting part 11d are made relatively thin. That is, it is possible to achieve both of the effects of reducing the thickness of the left side frame constituting part 11c and the right side frame constituting part 11d and improving the defense performance.

  Furthermore, since the projecting wall 90 is formed integrally with the main body portion of the right side frame constituting portion 11d by adopting the extrusion molding material, a gap may be generated between the projecting wall portion 90 and the main body portion. Moreover, since it becomes impossible to remove the protruding wall portion 90 and perform an illegal act, the defense performance against unauthorized unlocking is greatly improved.

  However, when the pachinko machine 10 is carried into the hall or at the time of carrying work in a factory or the like, the worker often performs the work with the left side frame constituting part 11c, the right side frame constituting part 11d, etc. of the outer frame 11, so that the right side If the protruding amount of the protruding wall portion 90 protruding from the inner surface of the frame constituting portion 11d is too large, problems such as difficulty in holding an operator may occur.

  In this regard, in the present embodiment, since the protruding amount of the protruding wall 90 is set to a relatively short position up to about a half of the left and right width of the locking device 600, such a problem is unlikely to occur.

  When the protruding amount of the protruding wall 90 is relatively short as described above, a gap is formed between the protruding wall 90 and the receiving metal 83 as described above, and the defense performance against unauthorized unlocking is reduced. However, if the resin cover 801 is provided as in this embodiment, such a concern can be eliminated.

  Moreover, it is difficult to arrange any member on the outer surface of the right side frame constituting portion 11d because the pachinko machine 10 installed in the island facility is adjacent to the other pachinko machine 10 and the like with almost no gap. On the other hand, as in the present embodiment, if the receiving metal fitting 83 and the resin cover 801 are assembled so as to sandwich the protruding wall portion 90 protruding from the inner surface of the right side frame constituting portion 11d, a great design change is made. Therefore, the metal fitting 83 and the resin cover 801 can be provided relatively easily.

  Furthermore, in the present embodiment, a tool G1 such as a flathead screwdriver can be inserted into the gap between the covering wall portion 801b and the protruding wall portion 90 of the resin cover 801, and the covering wall portion 801b can be separated relatively easily. For this reason, it is not necessary to perform laborious operations such as cutting the broken portions 801r one by one with a nipper or the like, and the work efficiency is good.

  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) In the above embodiment, regarding the locking mechanism of the inner frame 12, the inner locking members 615 and 623 are provided corresponding to both the inner flange members 613 and 614, and three locking mechanisms of the front frame set 14 are provided. The front lock members 619, 620, 621 are provided corresponding to all the front collar members 616, 617, 618. 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 613 and 614. 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 616, 617, and 618. If it is provided corresponding to at least one, the defense performance against unauthorized unlocking can be sufficiently exhibited.

  (C) The configuration of each lock member of the inner lock members 615, 623 and the front lock members 619, 620, 621 is not limited to the above embodiment. For example, in the above-described embodiment, the inner lock members 615, 623 and the front lock members 619, 620, 621 are rotationally displaced to change the state between the locked state (first state) and the unlocked state (second state). It is the composition to do. For example, a lock member that slides and moves in a substantially horizontal direction in conjunction with the operation of the sliding rod 610 may be employed by a rack and pinion mechanism.

  In the above embodiment, the inner lock members 615, 623 and the front lock members 619, 620, 621 are replaced with the corresponding inner flange members 613, 614, front flange members 616, 617, 618, and the sliding rod 610. Between the two. Not limited to this, the inner lock member 615 or the like may be disposed on the opposite side of the sliding rod 610 with respect to the inner rod member 613 or the like.

  Further, instead of the inner lock member 615 or the like that directly regulates the movement of the inner collar member 613 or the like, by regulating the movement of the sliding collar 610 when the inner frame 12 is closed, the collar member such as the inner collar member 613 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 lock member is pushed and displaced by coming into contact with a predetermined part such as the outer frame 11 or the receiving metal 83 and is slid by being inserted into a part of the sliding rod 610. An example is a configuration that engages with the collar 610 and restricts the movement of the sliding collar 610 and thus the inner collar member 613 and the like.

  Moreover, the cover member (the receiving metal fitting 83 and the resin cover 801) according to the present invention can also be applied to a configuration including only the inner flange member 613 and the like, in which the inner lock member 615 and the like are omitted.

  (D) The configuration of the inner flange members 613, 614 and the front flange members 616, 617, 618 is not limited to the above embodiment. For example, in the above-described embodiment, one sliding bar 610 is shared, and the inner frame 12 is unlocked and the front frame set 14 is separately unlocked. The inner flange members 613, 614 and the front flange members 616, 617, 618 are engaged with each other so as to be relatively displaceable. Instead, one of the inner flange members 613, 614 or the front flange members 616, 617, 618 may be provided on the sliding rod 610 so as not to be relatively displaced. As a configuration example, the inner flange member 613, 614 or the front flange member 616, 617, 618 is integrally formed with the sliding rod 610, or fixed to the sliding rod 610 so as not to be relatively displaced by a fixing means such as a screw. And the like. Even in such a configuration, depending on the relationship with a cylinder lock 700 and the like, which will be described later, when the inner frame 12 cannot be opened, the inner flange members 613 and 614 and the receiving metal fittings directly from the back side of the pachinko machine 10. There is no inconvenience in releasing the engagement with 83 and opening the inner frame 12.

  Also, two sliding rods that slide separately for the inner frame 12 and the front frame set 14 are provided, and the inner rod members 613, 614 and the front rod members 616, 617, 618 are provided for each sliding rod. May be provided so as not to be relatively displaceable.

  Moreover, in the said embodiment, although the inner collar member 613 grade | etc., Becomes a structure which slides to an up-down direction, not only this but the inner collar member 613 grade is rotationally displaced to the latching position and the non-locking position. You may employ | adopt the structure to do.

  In addition, the number of each flange member such as the inner flange member 613, each member to be engaged such as the receiving metal fitting 83 corresponding to this, and the number of each lock member such as the inner lock member 615 are limited to the number of the above embodiments. For example, there may be one corresponding to each locking mechanism such as the locking mechanism of the inner frame 12.

  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.

  (E) 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 releasing the inner frame 12 by releasing the engagement between the inner flange members 613 and 614 and the receiving fitting 83 directly from the back side of the pachinko machine 10.

  (F) In the above embodiment, the inner frame 12 is unlocked by inserting the key K into the key hole 702 of the cylinder lock 700 and rotating in the clockwise direction, and rotating in the counterclockwise direction. The frame set 14 is unlocked.

However, the present invention is not limited thereto, and the vertical wall portion 801a and the covering wall are not limited thereto. By providing a thin-walled portion between the portion 801b and the portion 801b, the two may be separated.

  Moreover, in the said embodiment, in order to make easy separation of the coating | coated wall part 801b, it becomes a structure by which the clearance gap which can insert tools G1, such as a flat-blade screwdriver, is formed between the coating | coated wall part 801b and the protrusion wall part 90. ing.

  However, the present invention is not limited thereto, and a configuration in which no gap is formed between the covering wall portion 801b and the protruding wall portion 90 may be employed. At this time, for example, a configuration in which a tool engaging portion into which the tool G1 can be inserted may be formed in the covering wall portion 801b itself. Moreover, it is good also as a structure which can provide the pick part etc. which can be picked by an operator's hand, and can cut off the coating | coated wall part 801b, without using a tool.

  (H) The configuration of the engaged member and the first cover member is not limited to the above embodiment. The structure, formation position, size, range, and the like can be changed as appropriate.

  For example, in the above-described 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. Yes. However, the present invention is not limited thereto, and these may be provided separately.

  Further, the fixing means for fixing the metal fitting 83 is not limited to the screw 799, and other fixing means such as a clip may be used.

  (I) In the above-described embodiment, the metal fitting 83 constituting the first cover member is made of metal, and the resin cover 801 constituting the second cover member is made of resin, and these are assembled. . However, the material and assembly structure of both cover members are not limited to the above embodiment. For example, both the cover members may be formed of a resin material or a metal material, or the first cover member may be made of resin and the second cover member may be made of metal.

  (J) In the above embodiment, for example, the urging force of the coil springs C1 and C2 is transmitted to the inner flange members 613 and 614 via the inner lock members 615 and 623, for example. That is, the urging means for the inner flange members 613 and 614 and the maintaining means for the inner lock members 615 and 623 are constituted by a single coil spring C1 and C2. Similarly, the urging means for the front saddle members 616, 617, 618 and the maintaining means for the front lock members 619, 620, 621 are constituted by a single coil spring C3, C4, C5. 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 indirectly to a collar member or a lock member via other members, such as the sliding rod 610.

  (K) In the above embodiment, the left side frame constituting part 11c and the right side frame constituting part 11d are made of an extruded material made of an aluminum alloy. However, the present invention is not limited to this, and may be made of another metal material. However, aluminum alloy is more preferable in terms of improving recyclability because it is relatively lighter and more workable than other metal materials. Further, the left side frame constituting part 11c and the right side frame constituting part 11d do not have to be extrusion molded products, and may be, for example, molded products.

  Moreover, in the said embodiment, although only the left side frame structure part 11c and the right side frame structure part 11d are metal, it is not restricted to this, You may make the upper side frame structure part 11a and the lower side frame structure part 11b metal. In this case, for example, two or three of the upper, lower, left and right frame components 11a to 11d, or all the frame components may be integrally formed.

  (L) In the above embodiment, the metal fitting 83 is fixed to the protruding wall 90 by the screw 799, and the screw 799 is covered by the covering wall 801b of the resin cover 801, so that the metal fitting 83 cannot be removed. It has become. However, the present invention is not limited to this, and a configuration may be adopted in which the metal fitting 83 and the resin cover 801 are assembled without using a fixing means such as a screw 799 so that the both are fixed to the protruding wall portion 90 so as not to be removed. For example, as shown in FIG. 37, the extending direction of the attachment portion 83f provided on the upper wall portion 83b and the attachment portion 83g provided on the lower wall portion 83c is directed inward of the cover, respectively. Thus, a configuration may be adopted in which a locking hole portion 83s is formed in which the locking claw of the locking piece 801g provided in the covering wall portion 801b of the resin cover 801 is locked. In this way, the locking piece 801g is locked in a manner that is not exposed to the outside of the receiving metal 83, so that the releasing operation of the locking piece 801g cannot be performed, and the receiving metal 83 and the resin cover Both 801 cannot be removed.

  Moreover, it is good also as a structure by which the metal fitting 83 is fixed with respect to the inner wall face of the right side frame structure part 11d of the outer frame 11 instead of the protrusion wall part 90. FIG. In such a case, the metal fitting 803 is fixed by screwing a screw from the outside of the right side frame constituting portion 11d. Thereafter, as in the above embodiment, the resin cover 801 is attached from the back side of the protruding wall 90. 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 screws are removed from the outside of the right side frame constituting portion 11d of the outer frame 11. become unable. As a result, the same effect as the above embodiment is achieved. For this reason, when releasing the engagement between the inner flange member 613 (614) and the receiving metal fitting 83 directly from the back side of the pachinko machine 10, the covering wall 801b is cut off in the same manner as in the above embodiment, and then the resin Remove the vertical wall portion 801a of the cover 801, insert a rod-shaped tool into the receiving metal fitting 83 from the gap where the vertical wall portion 801a is removed, perform the unlocking operation of the inner collar member 613 (614), and open the inner frame 12 Will be. More specifically, the lower piece 615c (623c) of the inner lock member 615 (623) is pushed forward by a rod-shaped tool inserted into the receiving metal fitting 83, and the lock by the inner lock member 615 (623) is released. Then, the head 613c (614c) of the inner flange member 613 (614) is pushed upward, the engagement between the inner flange member 613 (614) and the receiving metal fitting 83 is released, and the inner frame 12 is opened.

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

  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 configured in a rectangular frame shape;
On the front side of the fixed frame, a door body supported so as to be openable and closable on one side of the left and right frame components of the upper, lower, left and right frame components constituting the fixed frame;
A locking device that is provided on the door body, and that locks the door body on the fixed frame on the other side of the left and right frame components of 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,
At least the other side frame constituent part of the left and right sides of the fixed frame is formed of a metal material, and the inner side surface of the fixing frame extends along the vertical direction so as to cover the back side of the locking device. With a formed protruding wall,
A first cover member attached to the front surface side of the protruding wall portion and surrounding the engaged member and the flange member engaged with the engaged member;
A second cover member assembled to the first cover member from the back side of the protruding wall portion so as to sandwich the protruding wall portion;
By assembling the second cover member, the first cover member cannot be removed from the protruding wall portion.

  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 the 1st and 2nd cover 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.

  Moreover, in the state which assembled | attached the 2nd cover member, a 1st cover member cannot be removed from a protrusion wall part. Thereby, the suppression effect of the above-mentioned fraud etc. can further be heightened. Here, the phrase “the first cover member is“ unremovable ”” means that the first cover member cannot be removed or is extremely difficult unless it is removed by breaking the second cover member or the like.

  In general, after a gaming machine such as a pachinko machine is installed in an island facility of a gaming hall, other gaming machines and the like are arranged adjacent to each other. For this reason, if the first cover member is fixed to the inner side surface of the frame component from the outside of the fixed frame (the outer surface of the left and right frame components) by fixing means such as screws, the gaming machine is installed on the island facility Then, it becomes difficult to remove the first cover member. However, in a situation where the gaming machine is not installed in the island facility, the first cover member can be easily removed.

  On the other hand, in this means, the first cover member cannot be removed unless the second cover member is removed regardless of whether or not the gaming machine is installed in the island facility. Therefore, the defense performance against unauthorized unlocking is significantly improved as compared with the configuration in which the first cover member can be easily removed.

  On the other hand, for a valid reason such as when the lock member failed, it was necessary to release the engaged state with the engaged member by operating the saddle member directly from the back side of the gaming machine without using a key. In this case, the first cover member can be removed by breaking the second cover member or the like. 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 second cover member is removed by breaking it or the like, the trace remains there. Therefore, in the unlikely event that an illegal act is performed by destroying the second cover member, the illegal act can be detected early by confirming it. Therefore, it is possible not only to prevent fraud directly but also to prevent fraud from the aspect of early detection of fraud.

  As a result, the protection performance against unauthorized unlocking is significantly improved as compared with the configuration in which the first cover member can be easily removed while improving maintainability.

  It should be noted that the number of the hook members and the engaged members corresponding thereto is not limited to one, and a plurality of these members may be provided (the same applies to the cover members corresponding thereto). In this way, the defense performance against unauthorized unlocking can be further improved.

  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 controls 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.

  Conventionally, the fixed frame that supports the door body is configured in a rectangular frame shape by assembling wooden members. On the other hand, according to the above means 1, since the frame constituent part on at least the other side of the left and right sides of the fixed frame is made of metal, the durability is improved and the recyclability is improved as compared with the case of being made of wood. improves.

  Also, if the frame component is made of metal, the thickness can be made relatively thin while maintaining the required strength. In this way, the space surrounded by the fixed frame is expanded in the left-right width direction in a gaming machine whose outer shape is standardly configured to be substantially the same shape as a gaming machine such as a pachinko machine. Thus, the space can be used more effectively.

  However, when a metal member is employed, it is possible to reduce the weight and secure a sufficient strength even if the thickness is relatively thin, so that the thickness is considerably thinner than the wooden member. . For this reason, when performing an illegal act as described above, a wire such as a wire inserted from the side of the gaming machine can be relatively easily turned into the back side of the locking device, and the hook member can be operated. It becomes easy. That is, there is a concern that the above fraudulent acts are likely to be performed.

  On the other hand, according to this means, by providing the protruding wall portion that covers the back side of the locking device, it is possible to make it difficult to hook a wire or the like on the flange member, and it is possible to enhance the fraud prevention effect. Furthermore, by forming the protruding wall portion, it is possible to suppress the bending of the frame constituent portion. As the strength of the frame constituent portion is increased in this way, it is possible to further reduce the thickness, thereby reducing the weight and further expanding the internal space. In addition, by restricting the bending of the frame component, it becomes difficult to create a gap that allows the wire to enter by bending the frame component, thereby further improving the defense performance against unauthorized unlocking. Can do.

  However, when carrying a game machine into a hall or during a transport operation in a factory or the like, an operator often holds the frame components on both the left and right sides of the fixed frame, and thus projects to the inner surface of the frame component. If the protruding amount of the protruding wall portion is too large, problems such as difficulty in holding the operator may occur.

  In this regard, if the protruding amount of the protruding wall portion is shorter than the left and right width of the first cover member, such a problem is unlikely to occur. However, in such a configuration, a gap is formed between the projecting wall portion and the first cover member, and a wire or the like can enter the first cover member from this gap. There is a risk of the above fraudulent activity.

  On the other hand, since the gap between the protruding wall portion and the first cover member can be closed by providing the second cover member like this means, the defense performance against unauthorized unlocking is significantly improved.

  In addition, the gaming machine installed in the island facility is attached to the inner side surface of the frame component part by attaching the second cover member from the outer side surface of the frame component part because it is adjacent to other game machines with almost no gap. It is difficult to employ a structure that is assembled to the first cover member.

  On the other hand, in this means, since the first and second cover members are assembled so as to sandwich the protruding wall portion protruding from the inner surface of the frame constituting portion, without making a major design change. First and second cover members can be provided.

  Conventionally, when installing a gaming machine such as a pachinko machine in a gaming hall, it is common to fix the wooden fixing frame by hitting it with a nail or the like at the gaming machine installation location. Therefore, if the frame structure on both the upper and lower sides is made of a hybrid type, the gaming machine can be fixed with nails or the like as in the prior art, so there is no need for a new fixing means on the gaming hall side, The burden of is reduced.

Mean 2. A fixed frame configured in a rectangular frame shape;
On the front side of the fixed frame, a door body supported so as to be openable and closable on one side of the left and right frame components of the upper, lower, left and right frame components constituting the fixed frame;
A locking device that is provided on the door body, and that locks the door body on the fixed frame on the other side of the left and right frame components of the fixed frame;
The locking device is

A second cover member assembled to the first cover member from the back side of the protruding wall portion so as to sandwich the protruding wall portion;
The gaming machine according to claim 1, wherein the second cover member includes at least a covering portion that covers the fixing means so as not to be removed, and the covering portion is configured to be separable from the main body portion of the second cover member.

  According to the above means 2, since the second cover member includes the covering portion that covers the fixing means such as the screws so that the fixing means cannot be removed, the first cover member is the protruding wall portion in the assembled state to the first cover member. It becomes impossible to remove from.

  Furthermore, 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 operating the saddle member directly from the back side of the gaming machine without using a key. In this case, the shielding part can be separated and the fixing means can be removed.

  In addition, when the shield is separated, the trace remains there. Therefore, in the unlikely event that an illegal act is performed by destroying the second cover member, the illegal act can be detected early by confirming it. Therefore, it is possible not only to prevent fraud directly but also to prevent fraud from the aspect of early detection of fraud.

  As a result, the same effects as those of the means 1 are achieved.

  Note that “the fixing means cannot be removed” means that the fixing means and thus the first cover member cannot be removed or extremely difficult unless the covering portion is separated.

  Further, the “cutting off” of the covering portion includes breakage of the covering portion formed integrally with the main body portion of the second cover member, removal of a separate covering portion fixed to the main body portion of the second cover member, and the like. Meaning is included.

  Means 3. The gaming machine according to claim 2, wherein a gap portion into which a predetermined tool can be inserted is formed between the protruding wall portion and the covering portion.

  According to the means 3, a tool such as a flat-blade screwdriver is inserted into the gap, and a force is applied to the covering portion through the tool, so that the covering portion can be easily separated (broken). That is, by using a configuration that allows the covering portion to be separated using a tool, the covering portion can be provided more firmly, for example, integrally formed on the main body portion of the second cover member, and protection against unauthorized unlocking. Performance is greatly improved.

  Means 4. The gaming machine according to any one of means 1 to 3, wherein the first cover member is made of a metal member, and the second cover member is made of a resin member.

  According to the said means 4, sufficient defense performance with respect to unauthorized unlocking can be ensured by making the first cover member made of metal. Further, even when the second cover member is used by breaking it or the like, it is possible to restore the original state by simply replacing the used second cover member with a new unused second cover member. Therefore, it is not necessary to replace the first cover member, and the recyclability is excellent.

  Means 5. The gaming machine according to any one of means 1 to 4, wherein the engaged member and the first cover member are integrated.

  According to the above means 5, by integrating the engaged member and the first cover member, it is possible to reduce the number of parts and simplify the configuration.

Means 6. The first cover member is
A front wall portion having a fist hole portion through which the flange member is inserted;
A peripheral wall portion extending rearward from the peripheral edge portion of the front wall portion,
The second cover member is
The gaming machine according to any one of means 1 to 5, wherein the gaming machine is attached so as to close at least a gap between the opening on the rear side of the first cover member and the protruding wall portion.

  According to the above means 6, except for the hole portion through which the eaves member is inserted, it is possible to substantially prevent the intrusion of the wire from the six directions of up and down, left and right, and front and rear, and the protection performance against unauthorized unlocking is remarkably improved. improves.

  Mean 7 The gaming machine according to any one of means 1 to 6, wherein at least the other side frame constituting portion of the left and right sides of the fixed frame is made of an extruded material having a predetermined cross-sectional shape.

  According to the said means 7, since it does not need to perform the shaping | molding which used the die apparatus by comprising by an extrusion molding material, a manufacturing process can be simplified. Further, the protruding wall portion can be provided uniformly over the substantially entire region in the longitudinal direction of the frame constituent portion by extrusion molding.

  For example, it is very time-consuming to perform a process such as shortening the protruding amount of a part of the protruding wall portion so that the operator can easily hold it after extrusion. For this reason, when using an extrusion molding material, it is desirable to carry out extrusion molding in a state where the protruding amount of the protruding wall portion is set to be relatively small in advance so that the operator can easily hold it. In this case, there is a concern that a gap is formed between the protruding wall portion and the first cover member as described above. However, by providing the second cover member that can close the gap, such a case is provided. Can solve the problem. As a result, it is not necessary to perform a troublesome operation such as processing a part of the protruding wall portion after the extrusion of the frame constituent portion, and productivity can be improved.

  In addition, by adopting an extrusion molding material in which the protruding wall part is integrally formed with the main body part of the frame component part, it is impossible to remove the protruding wall part and perform an illegal act, so the defense performance against unauthorized unlocking Is significantly improved.
