  However, when the mechanism plate is opened or removed, it is troublesome to release the operation of a plurality of locking devices, and the locking devices provided on the left and right sides of the mechanism plate are conspicuous, so they are intentionally released. The lock provided on the upper part makes it easy to forget that when the mechanism plate is opened or removed, the mechanism plate does not move, and the lock on the upper part of the mechanism plate is released for the first time. It took time and effort. Moreover, if the removal of the locking tool is simplified, it will come off easily due to the ball load of the pachinko ball, making it meaningless.

  Accordingly, an object of the present invention is to solve the above-mentioned problems and to securely lock the mechanism plate in a use state of the pachinko gaming machine in which the front frame is closed to the machine frame, thereby preventing the mechanism plate from warping or bending. It is intended to provide a gaming machine.

  In order to solve the above-mentioned problems, the invention according to claim 1 is provided with a front frame that can be opened and closed on the front surface of a rectangular frame-shaped machine frame, and a back mechanism component such as a ball tank provided on the back surface side of the front frame. A pachinko gaming machine in which a mechanism plate is detachably provided, and the mechanism plate is housed in the machine frame by closing the front frame with respect to the machine frame, and engages with a peripheral portion of the mechanism plate A piece protrudes from the back side of the front frame, and the locking piece engages the mechanism plate with a predetermined engagement amount, and before the hook-like engagement portion is detached from the mechanism plate. And a rear portion that prevents separation from the mechanism plate by contacting the inner surface of the machine frame, and the rear portion faces the inner surface of the machine frame when the front frame is closed with respect to the machine frame. Thus, the closed state of the mechanism plate is maintained. The “peripheral part” here is not necessarily an end part, but also includes a locking hole or the like formed in the peripheral part, and further includes a back mechanism part such as a ball tank located in the peripheral part. The “back side of the front frame” as used herein is not limited to the front frame, but includes those located on the back side of the front frame such as a game board mounting frame. The mechanism plate may be provided to be rotatable or detachable with respect to the front frame. Further, the mechanism plate may be a single plate or may be divided into a plurality of pieces, and the mechanism plate may not necessarily be provided with a ball tank as a back mechanism component.

  The invention according to claim 2 is provided with a front frame that can be opened and closed on the front surface of a rectangular frame-shaped machine frame, and a mechanism plate that is provided with a back mechanism component such as a ball tank on the back surface side of the front frame. A pachinko gaming machine in which the mechanism plate is housed in the machine frame by closing the front frame with respect to the machine frame, and a locking piece having a hook-like engagement portion is provided on the back side of the front frame. When the mechanism plate is attached to the front frame, the hook-shaped engagement portion is engaged with the peripheral portion of the mechanism plate with a predetermined engagement amount, and the front frame is closed with respect to the machine frame. The closed state of the mechanism plate is maintained by setting the clearance between the inner surface of the machine frame and the locking piece to be smaller than the engagement amount. . Further, the “engagement amount” here means a distance in a locking direction of a portion where the hook-shaped portion and the mechanism plate overlap each other, and a more reliable locking is ensured as the engagement amount increases.

  The invention according to claim 3 is provided with a front frame on the front surface of a rectangular frame-shaped machine frame so that it can be opened and closed, and a mechanism plate provided with a back mechanism component such as a ball tank on the back surface side of the front frame. A pachinko gaming machine in which the mechanism plate is housed in the machine frame by closing the front frame with respect to the machine frame, and a locking piece that engages with a peripheral portion of the mechanism plate is provided on the back side of the front frame. And is provided with an interposition piece that is inserted into a gap between the inner surface of the machine frame and the locking piece, and the locking piece is formed by the interposition piece when the front frame is closed with respect to the machine frame. The detachment from the mechanism plate is prevented. The interposition piece may be provided integrally with the locking piece or may be formed separately, or may be provided on the machine frame side when formed separately. Thus, the engaging piece can be moved in the normal state in which the engaging piece is engaged with the mechanism plate by movably inserting the interposed piece into the gap between the inner surface of the machine frame and the engaging piece. The clearance can be set smaller than the amount of engagement with the mechanism plate to prevent the locking piece from being unnecessarily removed from the mechanism plate. The engagement of the locking piece can be released by retracting from the gap with the piece.

  It is preferable that the tip of the locking piece is formed as a tapered surface so that the locking plate acts in the unlocking direction when the mechanism plate contacts. Thus, by forming the tapered surface at the tip of the locking piece, the mechanism plate can be locked by a simple operation of pressing the mechanism plate against the tapered surface without directly operating the locking piece. I can do it.

  Also, a pachinko gaming machine in which a front frame is provided on the front side of a rectangular frame-like machine frame so that the front frame can be opened and closed, and a mechanism plate having a back mechanism part such as a ball tank is detachably provided on the back side of the front frame. A locking piece having a hook-like engaging portion and having elasticity is projected on the back side of the front frame so as to be in contact with the inner side surface of the machine frame, and the mechanism plate is mounted on the front frame. When mounted, the hook-like engagement portion is engaged with the peripheral edge of the mechanism plate with a predetermined engagement amount, and the mechanism plate is moved into the machine frame by closing the front frame with respect to the machine frame. When stored, the engagement amount may be maximized by the inner surface of the machine casing. Further, it is preferable that the end face on the machine frame side of the locking piece is tapered toward the tip, and the locking piece is reliably bent inward (locking direction) when contacting the machine frame. Can do. “Providing elasticity” as used herein means that the locking piece itself is made of synthetic resin or the like, so that elasticity is imparted by an elastic member such as a spring or a spring, even if elasticity is imparted due to the characteristics of the material. You may do it. The locking piece is formed with a hook-shaped engaging portion that engages with the peripheral edge of the mechanism plate with a predetermined amount of engagement, and faces the inner surface of the machine frame when the front frame is closed. It is preferable to provide a working piece that can come into contact with the inner surface.

  It is preferable to form the locking piece separately, and it is easy to replace even if the locking piece is broken, and the molding cost is reduced compared to the case where it is formed integrally with the front frame or the game board mounting frame. Is planned. The means for attaching the locking piece is not limited, and can be arbitrarily selected such as attaching with a screw or an elastic locking piece.

  It is preferable that the locking pieces are detachably provided and the locking pieces are attached to the front frame at a plurality of locations so that the mounting position of the locking pieces can be arbitrarily changed.

  Moreover, the attachment part of the said locking piece is not limited, It may be an upper part with respect to a mechanism board, right-and-left both sides, or a lower part. The gap in which the locking piece can move with the front frame closed is set to be smaller than the engagement amount of the locking piece so that the locking piece does not come off the mechanism plate.

  Further, although the locking piece is provided on the front frame side, the same effect can be obtained even if the locking piece is provided on the mechanism plate side and the locking piece is locked on the front frame side. . That is, a pachinko gaming machine in which a front frame is provided on the front surface of a rectangular frame-shaped machine frame so that the front frame can be opened and closed, and a mechanism plate having a back mechanism component such as a ball tank is mounted on the back surface side of the front frame. A locking piece having a hook-like engaging portion that engages the front frame and the mechanism plate with a predetermined engagement amount protrudes from either the front frame or the mechanism plate, and the front frame is used as a machine frame. On the other hand, when the mechanism plate is closed and accommodated in the machine frame, the gap between the locking piece and the machine frame may be set smaller than the engagement amount.

  Moreover, you may make it regulate the displacement amount to the releasing direction of a latching piece via another member, without restricting a latching piece directly by the inner surface of a machine frame. For example, the amount of displacement in the release direction of the locking piece may be regulated by a metal fitting that locks the front frame to the machine frame.

  The locking piece may be provided so as to be rotatable, and is preferably biased in the locking direction by an elastic member such as a spring. Further, depending on the mounting position of the locking piece, it may be rotated in the locking direction by its own weight without providing an elastic member.

  The pachinko gaming machine configured as described above has the mechanism plate locked by a locking piece that engages with a predetermined amount of engagement, thereby suppressing warpage and distortion, and particularly with the front frame closed. By setting the gap between the stop piece and the machine frame to be smaller than the engagement amount of the lock piece, the engagement of the lock piece is ensured, and as a result, the ball stops in the ball guide rod due to the warping of the mechanism plate. Can be prevented.

  According to the present invention, in the state of use of a pachinko gaming machine in which the front frame is closed to the machine frame, the mechanism plate is securely locked to prevent the mechanism plate from warping or bending, and the mechanism plate is opened or removed. In this case, the mechanism plate can be easily unlocked.

The locking piece 31 closes the front frame 2 with respect to the machine frame 1, and the mechanism plate 9 is housed in the machine frame 1. It is attached so that a clearance S1 between the end surface of the frame 1 and the inner surface of the machine frame 1 is set to be smaller than an engagement amount S2 between the hook-shaped engagement portion 32 and the mechanism plate 9. The “engagement amount” here means a distance in a locking direction of a portion where the hook-shaped engagement portion 32 and the mechanism plate 9 overlap each other, and the larger the engagement amount, the more reliable locking is ensured. Further, in the embodiment, a strip-shaped interval restricting portion 33 for setting the gap S1 is projected on the back surface portion of the locking piece 31, and a tapered surface 31b with the outer surface of the end of the interval restricting portion 33 facing the tip is provided. Thus, even when the front end of the locking piece 31 hits the front wall of the machine frame 1 when the front frame 2 is closed to the machine frame 1, the locking piece 31 is moved to the machine frame 1 by the tapered surface 31 b. It is possible to smoothly enter the inner surface. Note that the space restricting portion 33 is not necessarily provided, and the back surface portion of the locking piece 31 facing the inner surface of the machine casing 1 is used as a space restricting portion to directly restrict the gap with the inner surface of the machine casing 1. You may make it set to the space | interval to obtain.

The hinge of the plate member 60 may be provided on the reinforcing frame 64. For example, a shaft pin protruding upward is provided on the reinforcement frame 64, and a hinge portion having an axial hole is provided on the plate member 60 side. You can do it.

  As shown in FIG. 10, the reinforcing frame 64 has a U-shaped wiring housing portion 69 with one side open, and a synthetic resin lid member 70 is provided in the wiring housing opening so as to be freely opened and closed. The lid member 70 has a support shaft 71 formed on one side and a locking claw 72 provided on the other end, and a window portion 70a is formed at a predetermined location to guide the wiring of the ball dispensing device 47 and the like. It is preferable that a slit is provided in the vicinity of the support shaft 71 to give elasticity to the support shaft 71, and a slit or a through hole is formed in the vicinity of the locking claw 72 to give elasticity. Further, the shaft support piece 73 of the support shaft 71 is formed by bending the end portion of the reinforcing frame 64, and is supported by inserting the support shaft 71 into the shaft hole 74 formed in the shaft support piece 73. The locking claw 72 at the end is locked and fixed in a locking hole 75 formed in the reinforcing frame 64. At this time, since the support shaft 71 and the locking claw 72 are provided with elasticity, the mounting operation is facilitated. Further, the reinforcing frame 64 is extended to provide a support piece 76 that supports the side walls of the ball guide rod 44 and the ball dispensing device 47. The support piece 76 has a shape along the side wall of the ball guide rod 44 and the ball dispensing device 47, guards the side surface, and supports the side surface of the bent rod 44b and the ball dispensing device 47 so as to be tilted sideways. Is functioning to prevent. The lid member 70 is preferably molded from a clear material, and the wiring storage state of the wiring storage portion 69 can be visually confirmed. Further, the grounding iron plate provided on the bending rod 44b or the ball dispensing device 47 and the reinforcing frame 64 may be brought into contact with each other to discharge static electricity, and there is no troublesome wiring of the ground wire. Furthermore, the solenoid 51 and the motor as the electric drive source of the ball dispensing device 47 may be brought into contact with the reinforcing frame 64 to dissipate heat so as to increase the drive efficiency.

  The hinge tool 10 formed in this way is fixed to the front frame 2 and the mechanism plate 9 by screwing. In order to apply the wiring H to the wiring storage portion 69, the lid member 70 is opened to expose the wiring storage portion 69, the wiring H connected to the switchboard 46 is stored along the storage portion 69, and the lid member 70. It is only necessary to lock the locking claw 72 in the locking hole 75 and close the opening of the storage portion 69, so that the wiring can be easily stored and the operability is good. Then, the wiring H stored in the wiring storage unit 69 is connected to the payout control board 58 and the board box 59. Moreover, since the wiring storage part 69 is opened to the rear side, the lid member 70 can be opened even when the front frame 2 is closed, and wiring processing can be performed. Thus, by forming the wiring storage portion 69 with the metal reinforcing frame 64 which is a conductive member and storing the wiring, there is an excellent effect of blocking noise and preventing malfunction of the game. In addition, since the wiring H is stored in the wiring storage portion 69 provided in the hinge device 10, the wiring H does not come in contact with the hinge members 62 and 63 when the mechanism plate 9 is opened and closed by the hinge device 10. It is preferable that a groove is formed in the mechanism plate 9 or a guide rib is provided so that the mechanism plate 9 is reliably guided to the wiring housing portion 69. As a matter of course, the wiring H may be bound by a band or the like and stored in the wiring storage unit 69.

  Further, on the free end side of the mechanism plate 9, as shown in FIG. 7, a reinforcing plate 78 that reinforces the opening end of the upper and lower engagement holes 17 and adjusts the engagement with the hook-shaped piece 18 is provided on the mechanism plate. 9 are integrally formed by a connecting plate 79 provided along the side edge of 9. A part of the connecting plate 79 is formed in an L-shaped cross section, and a regulating piece 80 is provided at substantially the center to contact the guide piece 25 and guide the mechanism plate 9 to a predetermined position. The connecting plate 79 has mounting tongue pieces 78 a and 80 a of about 5 mm to 10 mm provided at the upper ends of the reinforcing plate 78 and the regulating piece 80 in a downward bag-like insertion hole 81 formed on the side edge of the mechanism plate 9. It is inserted by being screwed in the vicinity of the restricting piece 80 and screwed.

  Next, mounting of the mechanism plate 9 having the above configuration will be described. First, when the end of the movable hinge member 63 of the mechanism plate 9 is brought into contact with the guide portion 67 and the axis of the shaft pin 66 is positioned in the shaft hole 65 of the fixed hinge member 62 and is slid downward, the shaft pin 66 is moved. The mechanism plate 9 is inserted into the shaft hole 65 and attached to the front frame 2 so as to be opened and closed. Then, when the free end side of the mechanism plate 9 is closed so as to be pressed against the game board 5, the restricting piece 80 of the connecting plate 79 contacts the guide piece 25 of the locking device 11 to guide the mechanism plate 9 to a predetermined height position. At the same time, the hook-shaped piece 18 faces the engagement hole 17, and the hook-shaped piece 18 contacts the reinforcing plate 78 and is temporarily turned downward. Then, the hook-shaped piece 18 is returned and rotated by the urging of the spring 23 c to engage with the engagement hole 17, and the mechanism plate 9 is fixed to the game board 5 in close contact. Further, when the mechanism plate 9 is closed, the tip of the locking piece 31 comes into contact with the upper end of the peripheral edge of the mechanism plate 9, and the locking piece 31 is bent upward by elasticity as shown by a chain line in FIG. Simultaneously with closing, the hook-like locking portion 32 engages with the back surface of the mechanism plate 9. At this time, since the tip of the locking piece 31 is a tapered surface 31a, the operator can bend and lock the locking piece 31 to the mechanism plate 9 without touching the locking piece 31 directly. As described above, when the locking piece 31 is locked to the upper center of the mechanism plate 9, the contact state with the back surface of the game board 5 is always maintained firmly, and warping and distortion are suppressed. Then, when the front frame 2 fitted with the mechanism plate 9 is closed with respect to the machine frame 1 in this way, the flange 22 of the locking device 11 at the free end of the front frame 2 is locked to the receiving bracket 21 and locked. . At this time, as shown in FIG. 5, a gap S <b> 1 between the upper end of the locking piece 31 and the lower surface of the upper frame of the machine frame 1 is smaller than the engagement amount S <b> 2 between the hook-shaped locking portion 32 and the mechanism plate 9. In the unlikely event that an action force is applied to the mechanism plate 9 to expand rearward due to the ball weight of the pachinko ball housed in the ball tank 36, the locking piece 31 is warped in the direction of releasing. Even if it tries to bend, the upper end surface of the spacing regulating portion 33 of the locking piece 31 abuts against the inner surface of the machine frame 1 as shown in the chain line in FIG. The hook-like engagement portion 32 is not detached from the mechanism plate 9, and the fixed state of the mechanism plate 9 can be reliably held.

  Next, in order to open the mechanism plate 9, the cylinder lock 15 is operated with the key to rotate the cam plate 16, and the locking rod 13 is moved upward to release the engagement between the hook piece 22 and the receiving bracket 21. Then, the front frame 2 is opened. Then, with the front frame 2 opened, the operating portion 28 of the locking rod 13 is operated to move the locking rod 13 upward, and the hook-shaped piece 18 is rotated and engaged as shown in FIG. The engagement with the hole 17 is released, and the mechanism plate 9 can be opened. Although the locking piece 31 is locked to the upper edge of the peripheral edge of the mechanism plate 9, when the mechanism plate 9 is opened, the locking piece 31 is bent by the opening operation, and is engaged with the back surface of the mechanism plate 9. As a result, the mechanism plate 9 can be reliably opened.

  In this way, the opening and closing operation of the mechanism plate 9 can be engaged and disengaged using the bending of the locking piece 31 without directly operating the locking piece 31, and the front frame 2 is closed. In the state, when the locking piece 31 comes into contact with the inner edge of the machine frame 1, the hook-like engagement portion 32 is prevented from being detached. Therefore, the mounting of the mechanism plate 9 is easy to handle and the mounting is ensured. The locking piece 31 is mounted between the lower surface of the locking piece 31 and the upper surface of the game board mounting frame 4 with a space K where the locking piece 31 can bend. Can be further bent in the locking direction when engaged with the mechanism plate 9. At this time, the hook-shaped engaging portion 32 is in a state where the front frame 2 is released from the machine casing 1 and a part of the hook-shaped engaging portion 32 is locked to the mechanism plate 9. Even if the outer side surface of the locking piece 31 contacts the inner side surface of the machine frame 1 when the frame 2 is closed, the locking piece 31 can be bent inward by the space portion, so the front frame 2 is closed without any trouble. can do. On the other hand, the amount of engagement with the mechanism plate 9 is increased, and the mechanism plate 9 can be securely attached to prevent the mechanism plate 9 from warping or bending. Further, when the mechanism plate 9 rotates more than a predetermined angle, the horizontal plate-like portion of the movable hinge member 63 enters below the guide portion 67 and the guide portion 67 prevents the upward movement of the movable hinge member 63. The linkage of the mechanism plate 9 does not come off. For this reason, the mechanism plate 9 does not come off due to the momentum when the mechanism plate 9 is opened.

  FIG. 13 shows another embodiment of the locking piece 31. The difference from the above embodiment is that the locking piece 31 is elastically provided in advance so that it can be bent inward (in the locking direction). A space portion is provided on the joint portion 32 side, and the locking piece 31 and the inner end surface of the machine frame 1 can come into contact with each other when the front frame 2 is closed. In the embodiment, the action piece 86 that contacts the inner end face of the machine frame 1 is provided on the back surface portion of the locking piece 31, but the action piece 86 is not necessarily provided. You may make it make a back part contact the machine casing 1 directly. The action piece 86 has a tapered surface 31b that contacts the inner end of the machine casing 1 and faces the tip so that the locking piece 31 enters the inside of the machine casing 1. At this time, the hook-like engagement portion 32 of the locking piece 31 is in a normal state where it is locked to the mechanism plate 9 with the front frame 2 open, and is further locked even if the locking piece 31 is bent inward. It is formed in a size that has a margin to obtain. That is, in a normal state, a part of the tip of the hook-shaped engagement portion 32 is locked to the mechanism plate 9. When the front frame 2 is closed with respect to the machine frame 1 in this state, the tip tapered surface 31b of the action piece 86 comes into contact with the inner end of the machine frame 1, and the locking piece 31 enters the inside of the machine frame 1. Thus, the amount of engagement with the mechanism plate 9 is maximized, and the locking force can be further increased. As described above, since the locking force of the locking piece 31 is increased when the front frame 2 is closed, when the front frame 2 is released from the machine frame 1, the mechanism plate 9 may have some backlash. It only needs to be locked with a locking force of the level of temporary locking. When the front frame 2 is closed with respect to the machine frame 1, the locking piece 31 is always pushed in the locking direction by the machine frame 1 and locked. Since the force increases, the mechanism plate 9 can be firmly fixed. On the other hand, if there is no allowance (play) in the locking state between the locking piece 31 and the mechanism plate 9 in the normal state, precision is required at the time of design, which causes an increase in cost. Moreover, if there is even a slight error, it cannot be easily locked without using a hand, which takes time. For this reason, by providing this locking piece 31 not only on the upper side but also on the side or below, it is possible to reduce or eliminate the locking tool such as the hook-shaped piece 18 described above. In other words, in this embodiment, when the front frame 2 is closed with respect to the machine frame 1, the hook-like engagement portion 32 is operated by the locking piece 31 coming into contact with the inner surface of the machine frame 1. What is necessary is just to engage with the periphery of the board 9. Speaking extremely, even when the mechanism plate 9 is closed when the front frame 2 is opened, the hook-like engagement portion 32 may not be engaged with the mechanism plate 9.

  14 and 15 show still another embodiment of the locking piece 31. In this embodiment, the mechanism plate 9 can be opened even when the front frame 2 is closed to the machine frame 1. In the normal state where the front frame 2 is closed to the machine frame 1, the same as in the previous embodiment. In addition, a gap regulating piece 88 is used as an interposed piece for adjusting the gap between the inner surface of the machine frame 1 and the locking piece 31 so that the release of the locking piece 31 is prevented. It is provided so as to be movable so as to advance and retreat in the gap between the end surface of the machine 1 and the inner surface of the machine casing 1. When the gap regulating piece 88 is sandwiched in the gap between the inner surface of the machine frame and the locking piece, the gap S3 in which the locking piece 31 can move is the engagement of the hook-like engagement portion 32. The amount is set to be smaller than the amount S <b> 2, and the separation of the locking piece 31 from the mechanism plate 9 is prevented by the gap regulating piece 88. Further, when the front frame 2 is closed, the gap regulating piece 88 is retracted from between the inside of the locking piece 31 and the machine frame 1, and the back surface portion of the locking piece 31 is determined from the engagement amount S 2 of the locking piece 31. Since the clearance S1 with the inner surface of the machine frame 1 is large, the locking piece 31 can be released, and the mechanism plate 9 can be opened with the front frame 2 closed to the machine frame 1. The spacing regulating piece 88 is not necessarily provided integrally with the locking piece 31, but may be formed separately from the locking piece 31 and attached to the locking piece 31. Even if it is provided directly on the front frame 2, the game board mounting frame 4 or the machine frame 1 side, the same effect can be obtained.

  In addition, although the shape of the locking step portion 32a of the hook-shaped engaging portion 32 is substantially right-angled in the drawing, it can be easily detached from the mechanism plate 9 by making it obtuse, and conversely, the angle is made acute. It can be made difficult to come off, and can be set arbitrarily. At this time, even if the shape of the locking step portion 32a is an obtuse angle and can be easily detached from the mechanism plate 9, the locking piece 31 does not come off when the front frame 2 is closed. Further, the mounting of the locking piece 31 is screwed, but the mounting method can be changed as necessary, and it can be mounted with a separate locking tool or sandwiched by a reinforcing plate or the like. It may be. Further, for example, a bifurcated elastic locking piece is provided at the base end portion of the locking piece 31, and an engaging portion for locking the elastic locking piece is formed on the front frame 2, thereby engaging the elastic locking piece. The locking piece 31 may be fixed by locking to the joint. Preferably, a return is provided in the locking portion of the elastic locking piece so that the elastic piece does not bend inward by pulling.

  Further, the mounting position and the number of the locking pieces 31 are not limited in any way, and the mounting position may be the upper part, the right and left sides or the lower part with respect to the mechanism plate 9, and the mounting position is Not only the front frame 2 but also the game board mounting frame 4 may be provided. Further, the locking piece 31 may be locked to the back mechanism parts such as the ball tank 36 provided at the peripheral edge of the mechanism plate 9 without directly locking to the peripheral edge of the mechanism plate 9. Further, the locking piece 31 is not necessarily restricted directly by the inner surface of the machine frame 1, and the displacement amount of the locking piece 31 in the unlocking direction may be regulated via another member. A separate member for restricting the amount of displacement of the locking piece 31 in the unlocking direction is not provided separately. For example, the front frame 2 is free so as to lock the locking piece 31 to the side of the mechanism plate 9. When it is provided on the end side, the amount of displacement of the locking piece 31 in the unlocking direction may be regulated by the metal fitting 21 to which the collar piece 22 of the locking device 11 is locked. At this time, the restricting member such as the catch 21 for restricting the displacement amount of the locking piece 31 in the unlocking direction is such that the locking piece 31 can easily enter the inner surface of the machine frame 1. It is preferable to form it as a tapered surface toward the surface. Further, when the locking pieces 31 are separately attached, mounting portions for the locking pieces 31 are provided at a plurality of locations, and the mounting location and the number of mountings can be arbitrarily changed depending on the bending state of the mechanism plate 9 or the like. Is preferable. The locking piece 31 may be provided integrally with the front frame 2 or the game board mounting frame 4. Further, a leaf spring or the like may be provided on the peripheral edge portion of the mechanism plate 9 corresponding to the locking step portion 32a of the hook-shaped locking portion 32 or the locking piece 31, so that the locked state is ensured.

  The locking piece 31 is not limited to a synthetic resin, but may be formed of a metal piece, a leaf spring, or the like to provide elasticity, and the locking piece 31 may be an elastic member such as a spring or a spring. By interposing, elasticity may be provided in the locking direction. At this time, the locking piece 31 is preferably provided so as to be rotatable or slidable as shown in FIG. However, depending on the mounting location of the locking piece 31, the locking piece 31 may be urged in the locking direction by its own weight without using an elastic member. In particular, as shown in the embodiment, when the locking tool 31 provided on the side is released as the hook-shaped piece 18 to release the locking, the locking tool 31 is as shown in FIG. All the hooks 18 that lock the mechanism plate 9 by operating the operation portion 28 by making the hook-like piece 18 and the locking piece 31 cooperate in a synchronized manner by a link or the like so as to be rotatable. It is preferable to be able to unlock the tool. In addition, when providing the said locking piece 31 so that rotation is possible, it is preferable to form a shaft support part in the front frame 2 or the game board mounting frame 4 integrally.

  Further, although the locking piece 31 is provided on the front frame 2 side, the same is true if the locking piece 31 is provided on the mechanism plate 9 side and the locking piece 31 is locked on the front frame 2 side. The effect of can be produced. A locking piece 31 having a hook-like engagement portion 32 for engaging and disengaging the mechanism plate 9 with the front frame 2 is provided, and the front frame 2 that has locked the mechanism plate 9 by the locking piece 31 is closed to the machine frame 1. In this state, the distance between the end surface of the locking piece 31 on the machine frame 1 side and the inner surface of the machine frame 1 may be set smaller than the engagement amount that the hook-shaped engagement portion 32 is locked to the mechanism plate 9. . Further, the mechanism plate 9 may be a single plate or may be divided into a plurality of pieces, and the ball plate 36 may not necessarily be provided on the mechanism plate 9 as a back mechanism component. Needless to say, when the mechanism plate 9 is divided and formed, the locking pieces 31 may be provided corresponding to the four side (upper, lower, left and right) peripheral edges of the mechanism plate 9, respectively. Further, even if the receiving bracket 21 is extended and directly brought into contact with the rear surface of the mechanism plate 9 in place of the locking piece 31, the mechanism plate 9 can be prevented from being bent or warped.

  The cover member 34 is not limited to the form of the embodiment. Even if the entire cover member 34 is formed separately from the mechanism plate 9, the standing wall 34 a of the cover member 34 is formed integrally with the mechanism plate 9. The lid portion that closes the rear surface may be formed separately. The standing wall 34a on the lower surface of the cover member 34 is not necessarily provided, and the strength can be maintained if there is at least the upper surface and side surfaces. That is, the standing wall 34a may be a downward U-shape or an inverted L-shape, and when the side wall 34a is on one side, it is preferably on one side of the ball dispensing device 47 side. At this time, the other side may be provided so as to be openable / closable or detachable together with the lid. Further, the ball guide rod 44 and the ball dispensing device 47 located on the side of the cover member 34 may be directly attached along the standing wall 34a of the cover member 34. When the cover member 34 is formed separately from the mechanism plate 9, the cover member 34 can be a unit including a ball guide rod 44 and a ball dispensing device 47. Note that at least a part of the passages 45 and 49 of the ball guide rod 44 and the ball dispensing device 47 may be provided in the cover member 34. In addition, a wiring storage portion for storing the wiring of the ball payout device 47 may be provided along the cover member 34, and is preferably located on the rear surface of the ball guide rod 44 and the ball payout device 47, And it is good to provide so that the rear surface of the ball dispensing device 47 may be protected. Needless to say, a unit base in which the ball guide rod 44 and the ball dispensing device 47 are previously unitized may be attached to the cover member 34, and the ball guide rod 44 and the ball dispensing device 47 are attached to the unit base. A protective cover can be provided. Further, a locking portion for locking the lid portion of the cover member 34 may be formed on the unit base.

  In the above embodiment, the mechanism plate 9 is detachably mounted by the hinge device 10, but the mechanism plate 9 may be directly detachably attached to the front frame 2 by a fixing device, as shown in FIG. The same components as those in the above embodiment will be described with the same reference numerals. Note that the locking piece 31 is provided at substantially the center of the mechanism plate 9 as in the above embodiment. Then, as shown in FIG. 17, the fixture is composed of a hook-shaped piece 18 as a vertical locking member attached to the front frame 2 side and a vertical engaging member 90 attached to the mechanism plate 9 side. The upper and lower engaging members 90 are integrally formed by a reinforcing frame 64, and the reinforcing frame 64 is provided with a wiring storage portion 69 having the reinforcing frame 64 at least on one side. Specifically, the wiring housing portion 69 is formed such that one side is opened when the reinforcing frame 64 is bent and the reinforcing frame 64 is attached to the mechanism plate 9. Further, the engaging member 90 is integrally formed by a reinforcing frame 64 at a position corresponding to the hook-shaped piece 18 of the mechanism plate 9. Further, the engagement member 90 has an engagement hole 89 with which the hook-shaped piece 18 is engaged. The degree of bending of the cut-out piece 89 a formed by cutting the engagement hole 89 is different from that of the hook-shaped piece 18. The degree of engagement can be adjusted. On the other hand, the connecting rod 91 provided with the flange-like piece 18 is slidably disposed with respect to the mounting plate 87 provided on the front frame 2. The connecting rod 91 is provided with a bent operation portion 91a. Thus, when the mechanism plate 9 is made detachable without being pivotally supported, it is preferable to provide support means such as a guide piece for maintaining the closed state of the mechanism plate 9. It is preferable to engage the hook-shaped piece 18 and the engaging portion 17 so as to be a fulcrum (positioning) of the mechanism plate 9 at the time of mounting. The support means may be configured to hook the upper portion of the mechanism plate 9 or to support the lower portion of the mechanism plate 9. The support portion at this time is preferably provided integrally with the reinforcing frame 64 and the connecting member 68. Further, the fixing tool is not limited to the hook-shaped piece 18 shown in the embodiment, and various other forms such as locking the hook-shaped piece 18 by a locking tool as a fixed one can be considered.

  The mechanism plate 9 configured as described above engages the hook-like piece 18 of the locking device 11 and the hook-like piece 18 provided on the connecting hook 91 by supporting the regulating piece 80 of the connecting plate 79 on the guide piece 25. The mechanism plate 9 is detachably attached to the front frame 2 by engaging the holes 17 and 89 and locking the locking piece 31 to the upper end of the mechanism plate 9. When the front frame 2 having the mechanism plate 9 mounted thereon is closed with respect to the machine frame 1, the locking piece 31 is not disengaged because the displacement amount is regulated by the inner surface of the machine frame 1, and the ball load It is also possible to reliably prevent the bending due to. Further, in order to remove the mechanism plate 9, the locking device 11 is operated with a key to open the front frame 2 and the operating portions 28 and 91 a are operated to operate the locking rod 13 and the connecting rod 91 in the same manner as in the above embodiment. By sliding upward, the engagement between the hook-shaped piece 18 and the engagement holes 17 and 89 is disengaged, and when the mechanism plate 9 is further removed, the locking piece 31 is bent and the engagement with the mechanism plate 9 is released. The locking piece 31 can be removed without directly operating.

  Further, in order to simplify the release of the hook-like piece 18, a lever member is provided via a link member or the like so that the locking hook 13 provided with the hook-like piece 18 and the connecting hook 91 can be operated simultaneously. Is preferred. By operating this lever member, the locking rod 13 and the connecting rod 91 can move simultaneously, and the engagement between the hook-shaped piece 18 and the engagement holes 17 and 89 can be released at once, and the mechanism plate 9 Is easy to remove.

  Further, the mounting plate 87 provided along the game board mounting frame 4 and the substrate 12 of the locking device 11 may be a part or one side directly constituting the game board mounting frame 4. Further, as shown in FIG. 17, on the mounting plate 87 and the base plate 12 of the locking device 11, a regulation piece 120 (position on the drawing) for positioning when the game board 5 is mounted on the game board mounting frame 4 from the front or rear side. The positioning of the rear surface of the game board 5 may be extended. Preferably, an elastic piece is provided on the contact surface of the game board 5 of the restriction piece so that the game board 5 is pressed. At this time, the board 12 and the mounting plate 87 may be formed in a front L shape or a U shape so that the board 12 and the mounting plate 87 form a corner of the game board mounting frame 4. In addition, a restriction piece for positioning when the game board 5 is mounted on the game board attachment frame 4 from the front surface or the rear surface may be extended to the board 12 and the attachment plate 87, and preferably the game of the restriction piece. It is preferable that an elastic piece is provided on the contact surface of the board 5 by spot welding or the like so that the game board 5 is pressed. The restricting piece may be wave-shaped, or a slit may be provided in the restricting piece so that the restricting piece is slightly raised to directly form an elastic piece on the restricting piece. Further, an attachment portion for attaching the fixture of the game board 5 may be extended or formed on the substrate 12 and the mounting plate 87, and the fixture may be rotatably provided on the attachment portion by a screw. do it. As described above, by providing the locking device 11 with the accompanying tools (position restricting pieces, fixing portion attaching portions, etc.) located in the vicinity of the locking device 11, processing and assembly are facilitated, and the cost is reduced. Can also be reduced. In addition, a flat or U-shaped reinforcing metal plate may be attached to the upper surface of the game board mounting frame 4, and the locking piece 31 may be directly attached to the reinforcing metal or the locking piece 31 may be rotated. You may provide the axial support part at the time of making it movable.

  In the embodiment, the wiring storage portion 69 is provided on the reinforcing plate 64, but the wiring storage portion 69 in the mechanism plate 9 is not limited in any way. For example, the wiring storage portion 69 is on the back side of the mechanism plate 9. You may make it provide in. Specifically, as shown in FIGS. 18 and 19, a bearing piece 73 having a shaft hole 74 is provided at one end of the reinforcing plate 64, and a holding piece 93 of the lid member 70 is bent and provided. Further, a locking hole 94 for the lid member 70 is formed on the other side wall of the wiring storage portion 69 formed in the mechanism plate 9. On the other hand, the lid member 70 has shaft portions 71 projecting from both ends, and one side in the short side direction engages an elastic locking piece 95 formed by a cut groove with the locking hole 94. The operation knob 96 for releasing the engagement to the outside of the elastic locking piece 95 is slightly protruded. A through hole 97 is formed at an appropriate position on the shaft support side so as to avoid the presser piece 93 when rotating. The elastic locking piece 95 hangs downward and is provided with a locking claw 95a on the wiring storage portion 69 side. The opening formed in the elastic locking piece 95 is a molding hole for molding the locking claw 95a. Further, on the lower surface of the lid member 70, rib-shaped presser portions 98 that are pressed so as not to bite the wiring H when the lid member 70 is closed are formed at predetermined intervals. Accordingly, a slit 99 into which the holding portion 98 is fitted is formed on the side wall of the wiring storage portion 69. In addition, the shaft hole 74 is formed in the bearing piece 73. However, the bearing piece 73 is formed with a notch that opens toward the reinforcing plate 64, and the open end side of the notch is closed by the reinforcing plate 64. It is good also as a bearing of a shaft part.

  20 to 22 show another embodiment of the shaft support structure of the lid member 70.
