JP 2009-291520 A

  By the way, in the pachinko gaming machine described above, if there is even a gap between the front door and the gaming machine main body, a piano wire or the like is inserted between the front door and the gaming machine main body through this gap. By illegally operating the game, there is a risk that an illegal act of acquiring a large number of game balls (so-called goto action) may be performed.

  As a measure for preventing such an illegal act, it can be considered that a security plate is attached to the gaming machine main body from its board side so as to eliminate the gap between the gaming machine main body and the front door.

  However, when the security board is mounted in this way, the gap between the game board and the security board becomes too narrow, and so-called ball biting occurs in which the game ball is pinched immovably between the game board and the security board. There is a fear.

  In response to this, a security plate may be provided on the gaming machine body so that it can be opened and closed from the side of the board, so that when the ball bite occurs, the security plate may be opened. However, even if the ball biting can be eliminated by opening the security plate, there is a problem that the security of the pachinko gaming machine is lowered.

  In view of the above, the present invention provides a security board that can be opened and closed on the gaming machine body from the gaming board side, and the security board is installed when the security board is closed. It is an object of the present invention to provide a pachinko machine capable of preventing cheating while eliminating the ball bite, based on a configuration that allows the ball bite to be released in this locked state. And

In solving the above-described problems, the present invention provides a method according to claim 1.

  According to this, the security board is supported so that opening and closing is possible between the gaming machine main body and the front door.

  For this reason, when the security board is closed, no gap is formed between the security board and the gaming machine main body. Therefore, even if a piano wire or the like can be inserted through the gap between the gaming machine body and the front door, it is difficult to insert the piano wire or the like between the security board and the gaming machine body.

  Therefore, the piano wire or the like cannot reach the board surface of the game board, and as a result, the above-described fraud can be prevented.

  Further, since the security plate is locked by the lock mechanism when closed, the security plate cannot be freely opened. For this reason, the security of the pachinko gaming machine is improved.

  In addition, when a game ball is bitten between the game board and the transparent plate of the security plate, the displacement plate member is released by the displacement mechanism while the front door is closed and the security plate is locked. Since it is possible to displace forward in the holding frame, the above-mentioned ball biting can be eliminated without opening the front door and the security plate, which is convenient.

  At this time, since the security plate remains locked as described above, the security of the pachinko gaming machine is improved in the same manner as before the elimination of the ball bite. In addition, since the board surface of a game board can be visually recognized through the transparent board of a security board, especially trouble does not arise in visually recognizing a board surface from a front door.

  The arcuate surface cam surface 74b has an outwardly convex longitudinal cross-sectional arc shape centering on the center of each shaft hole portion of each of the left and right cam members 74 (the axis of the left and right direction shaft 72c). It is formed in the counterclockwise direction from the counterclockwise end. Thereby, each of the left and right side cam members 74 maintains the glass plate 64 of the displacement plate member 62 at the advanced position under the engagement of the arcuate cam surface portion 74b with the upper wall 63c of the holding frame 63.

  As shown in FIG. 10, the lower rotation cam mechanism Bd has a bevel gear 73 b that meshes with the bevel gear 73 a of the rotation transmission mechanism Bb, and left and right cam members 75. The bevel gear 73a is supported by the right end portion of the left-right direction shaft 73c so as to face the right at the tooth portion, and meshes with the bevel gear 73a.

  Here, the left-right direction shaft 73c is rotatably supported at the left end portion thereof from the left end portion of the upper surface by the lower wall 61d of the holding frame 61 via a bearing 86 (see FIG. 10). The right end portion of the shaft 73c is rotatably supported by the lower wall 61d from the upper right end portion side. Thereby, the left-right direction shaft 73c is rotatably supported so as to extend in the left-right direction on the upper surface along the lower wall 61d of the holding frame 61, and the bevel gear 73b is supported by the shaft of the bevel gear 73a. It is meshed with the bevel gear 73a so as to be orthogonal to the axis. This means that the lower rotation cam mechanism Bd converts the rotation around the vertical axis 71d to the rotation around the left and right axis 73c perpendicular to the vertical axis 71d. To do.

  The left and right side cam members 75 are coaxially supported at the axial intermediate portions of the left and right direction shafts 73c at the respective shaft hole portions and are opposed to the left and right side cam members 74, respectively. The left and right side cam members 75 rotate in the same direction in conjunction with the left and right direction shaft 73c.

  Further, the left and right side cam members 75 are respectively connected to the axis of the left and right direction shaft 73c so that the cam surfaces engage with the lower wall 63d of a holding frame 63 (described later) of the displacement plate member 62 from the rear surface side. It is supported at the middle part in the direction.

  Here, the cam surfaces of the left and right side cam members 75 are configured in the same manner as the cam surfaces of the left and right side cam members 74, and the cam surfaces of the left and right side cam members 75 are shown in FIGS. As shown in FIG. 18, the flat cam surface portion 74a and the circular arc surface cam surface portion 74b respectively correspond to the flat cam surface portion 74a and the circular arc surface cam surface portion 74b.

  Thus, as will be described later, the planar cam surface portion 75a is formed in a linear shape in a longitudinal section so as to displace the glass plate 64 of the displacement plate member 62 from its original position to its forward position (or from its forward position to its original position). ing. Accordingly, each of the left and right cam members 75 is engaged with the lower wall 63c of the holding frame 63 by the cam surface portion 75a, and the rotation position shown in FIG. 16 (hereinafter referred to as the lower original rotation angle position). 17) to a rotation position (also referred to as a lower forward rotation angle position) shown in FIG. 17 and FIG. 18, and is counterclockwise from the advance rotation angle position to the original rotation angle position. Rotate clockwise.

  The arcuate cam surface portion 75b is a longitudinally arcuate section that is outwardly convex with the center of the shaft hole portion of each of the left and right cam members 75 (the axis of the left and right direction shaft 73c) as the center of the cam surface portion 75a. It is formed clockwise from the clockwise end. Thereby, each of the left and right side cam members 75 maintains the glass plate 64 of the displacement plate member 62 at the advanced position under the engagement with the lower wall 63d of the holding frame 63 by the arcuate cam surface portion 75b.

  As shown in FIG. 10, the lock mechanism B <b> 2 has a bevel gear 92 and a lock lever 92. The bevel gear 92 is pivotally supported by the shaft at the intermediate portion in the vertical direction of the right wall 61b of the holding frame 61 via the bearing 93 from the left surface side. Thus, it is positioned so as to be coaxially opposed to the tooth portion of the bevel gear 71a and meshes with the bevel gear 71b.

  The lock lever 92 is coaxially supported by the shaft of the bevel gear 92 at the base end portion thereof, and the lock lever 92 extends from the base end portion so as to be orthogonal to the shaft of the bevel gear 92. Thus, it can be locked to a locking member 41c provided on the right wall 41b of the frame H. In this embodiment, the locking member 41c is mounted on the front surface of the right wall 41b of the frame H at both legs, and the locking member 41c is at the U-shaped locking portion 41d. It projects in a U-shape forward from each opposed end of both legs.

  Thus, the lock lever 92 is locked in the locking portion 41d of the locking member 41c at its extended end by rotating in the clockwise direction shown in FIG. 19, and FIG. 20 and FIG. As indicated by 21, it is disengaged from the locking portion 41d of the locking member 41c by turning counterclockwise.

This is because the lock mechanism B2 is engaged with the holding frame 61 (in other words, the security plate S) by the engagement of the locking member 41c of the lock lever 92 in the position shown in FIG. ) Is locked to the frame H, and the lock is released by disengagement from the U-shaped locking portion 41d of the locking member 41c of the lock lever 92 that rotates counterclockwise as shown in FIGS. It means to do.

  As shown in any of FIGS. 7 to 12, the displacement plate member 62 includes a regular octagonal holding frame 63 and a regular octagonal glass plate 64, and the glass plate 64 is composed of the holding frame 63. Is fitted into the regular octagonal hollow portion. The holding frame 63 is formed in a regular octagonal shape as described above by the right wall 63a, the left wall 63b, the upper wall 63c, the lower wall 63d, and the inclined walls 63e.

  As shown in FIG. 7, the displacement plate member 62 configured in this manner is arranged in the following manner between the upper wall 61a and the lower wall 61d of the holding frame 61 with respect to the upper wall 61a and the lower wall 61d. It is assembled in the rectangular hollow portion of the holding frame 61 so that it can be displaced in the direction.

  Here, the displacement plate member 62 has two sets of both guide pins 63g (see FIG. 10) on both the upper and lower sides, and the upper guide pins 63g are respectively the holding frame on the upper wall 63c of the holding frame 63. The upper wall 61a of the upper wall 61a protrudes upward from the corresponding portions of the corresponding linear elongated hole portions 61e. Thus, the upper guide pins 63g are inserted into the corresponding linear elongated holes 61e so as to be relatively displaceable in the longitudinal direction (front-rear direction). The upper guide pins 63g are press-fitted into the respective press-fitting hole portions 63f formed in the corresponding portions of the upper wall 63a with respect to the two linear elongated holes 61e of the upper wall 61a and protrude upward.

  The lower guide pins 63g protrude downward from the corresponding portions of the lower wall 63d of the holding frame 63 with respect to the corresponding linear elongated holes 61e of the lower wall 61d of the holding frame 61, respectively. It is inserted into the corresponding linear slot 61e so as to be capable of relative displacement in the longitudinal direction (front-rear direction). The lower guide pins 63g are press-fitted into the respective press-fitting hole portions formed at the respective portions of the lower wall 63d facing the linear elongated holes 61e of the upper and lower walls 61d and protrude downward. Yes.

  As a result, the displacement plate member 62 is displaced in the front-rear direction along the linear elongated holes 61e with respect to the upper and lower walls 61a and 61d between the upper and lower walls 61a and 61d in the holding frame 61 as described above. It is possible.

  In the first embodiment, as will be described later, the position at which the ball of the game ball can be eliminated between the glass plate 64 and the board surface 31 of the game board P in accordance with the forward displacement of the displacement board member 62 (displacement board member 62). Each of the advancing positions where the left and right upper guide pins 63g reach within the left and right upper linear elongated holes 61e, and the predetermined longitudinal intermediate portion of the left and right upper linear elongated holes 61e. At the same time, each advance position where the left and right lower guide pins 63g reach within the left and right lower straight elongated hole portion 61e is made to correspond to each predetermined front-rear direction intermediate portion of the left and right lower straight elongated hole portion 61e. It is set to. Therefore, in order to disengage the tool T from the locking with the locking member 41c as described above, the left and right upper guide pins 63g are moved to the left and right upper linear shapes by rotating the tool T in the further clockwise direction as described above. The left and right lower guide pins 63g are moved to the rear end portions of the left and right lower linear straight hole portions 61e while being moved to the rear end portions of the long hole portions 61e.

  Further, by assembling the displacement plate member 62 in the holding frame 61 as described above, a triangular space is formed between each corner portion of the holding frame 61 and the corresponding inclined wall 63e of the holding frame 63. G is formed, and each void G plays a role of inserting each decorative component 35 of the game board P as illustrated in FIG. In addition, when opening and closing the security plate S, the opening shape of each void G is formed large so that each decorative component 35 does not interfere with the inner periphery of each corresponding void G.

  In the first embodiment configured as described above, in the pachinko gaming machine, it is assumed that the front door D is in a state of closing the frame H together with the security S via the game board P.

  In such a state, as shown in FIG. The flat cam surface portions 74a engage with the rear surface of the upper wall 63c of the holding frame 63, and the upper guide pins 63g are respectively connected to the corresponding upper coiled torsion as shown in FIGS. The spring force of the spring 61g is held in a state of being pressed against the rear end portion of each corresponding linear elongated hole portion 61e of the upper wall 61a. Further, as shown in FIG. 16, both the lower cam members 75 are engaged with the rear surface of the lower wall 63d of the holding frame 63 at the planar cam surface portion 75a, and the lower guide pins 63g are respectively The corresponding lower coiled torsion spring 61g is held in a state of being pressed against the rear end portion of each corresponding linear elongated hole portion 61e of the lower wall 61a. As a result, the displacement plate member 62 is held in the original position as shown in FIGS. 4, 8 and 9.

  Further, as shown in FIG. 19, the lock mechanism B2 locks the security plate S to the frame H by locking the lock plate 92 to the locking portion 41c of the locking member 41d of the frame H. Yes.

  In such a state, the security board S closes the gaming machine main body via the game board P. For this reason, a slight gap does not occur between the security plate S and the gaming machine main body.

  Therefore, even if a gap is generated between the front door D and the gaming machine body, no gap is generated between the security plate S and the gaming machine body as described above.

  For this reason, even if a fraudulent person enters a piano wire or the like through a gap between the front door D and the main body of the gaming machine in order to cheat on the pachinko gaming machine, the board surface of the gaming board P Since 31 is covered with the security board S, it is difficult to let a piano wire etc. approach from between the security board S and the said game machine main body. This means that the above-described fraud can be prevented in advance.

  In such a state, in the game process by the pachinko gaming machine, the game ball is sandwiched between the displacement plate member 62 and the board surface 31 of the game board P, so that the so-called ball biting is performed on the board surface of the game board P. When it occurs between 31 and the displacement plate member 62, the security plate S remains closed in the locked state by the lock mechanism B2 as described above. Therefore, even if the front door D is opened and the security plate S is opened, it cannot be opened.

  Therefore, for example, the operator of the hole grips the grip portion of the shaft tool T, inserts the shaft portion Ta into the tool insertion hole 18 of the front door D, and inserts the shaft portion Ta before and after the rotating device B. It connects with the direction axis 71c.

  When the shaft tool T is rotated clockwise as shown by an arc-shaped arrow in FIG. 11 against the urging force of each torsion spring 61g, the front-rear shaft 71c is pivoted in the front-rear shaft mechanism Ba. The bevel gear 71a is rotated in the same direction as the longitudinal axis 71c.

  Along with this, the bevel gear 71b is rotated by the bevel gear 71a while meshing with the bevel gear 71a, and the vertical shaft 71d of the rotation transmission mechanism Bb is moved together with both bevel gears 72a and 73a. It rotates in the same direction as the bevel gear 71b (see the arrow direction shown in FIG. 11).

  When the bevel gear 72a is rotated as described above, the bevel gear 72b of the upper rotation cam mechanism Bc is rotated by the bevel gear 72a while meshing with the bevel gear 72a, so that the upper left-right axis Together with the 72c and the upper cam members 74, it rotates in the direction of the arrow shown in FIG. When the bevel gear 73a is rotated as described above, the bevel gear 73b of the lower rotation cam mechanism Bd is rotated by the bevel gear 73a while meshing with the bevel gear 73a. Together with the side left-right direction shaft 73c and the lower cam members 75, it rotates in the direction of the arrow shown in FIG.

  When the upper cam members 74 are rotated as described above, the upper wall 63c of the holding frame 63 of the displacement plate member 62 is pushed forward by the upper cam members 74 at the respective planar cam surface portions 74a. Is moved (see FIG. 13). At this time, the upper guide pins 63g move forward along the corresponding linear elongated holes 61e against the urging forces of the upper torsion springs 61g. When the upper cam members 75 are rotated as described above, the lower wall 63d of the holding frame 63 is pushed forward by the upper cam members 75 at the respective planar cam surface portions 75a (see FIG. 16). At this time, the lower guide pins 63g move forward along the corresponding linear elongated holes 61e against the urging forces of the lower torsion springs 61g. Thus, the displacement plate member 62 is displaced forward from the original position in the holding frame 61.

  In such a state, each of the upper cam members 74 finishes engaging with the rear surface of the upper wall 63c of the holding frame 63 by the respective planar cam surface portions 74a, and as shown in FIGS. The arc-shaped cam surface portion 75b engages with the rear surface of the upper wall 63c of the holding frame 63, and both the lower cam members 75 engage with the rear surface of the lower wall 63d of the holding frame 63 by the respective planar cam surface portions 75a. Then, as shown in FIGS. 17 and 18, each arcuate cam surface portion 75b engages with the rear surface of the lower wall 63d of the holding frame 63. At this time, the upper guide pins 63g and the lower guide pins 63g engage with the front end portions of the corresponding linear elongated holes 61e of the holding frame 61, respectively.

  This means that the displacement plate member 62 is displaced to the forward position, and the distance between the glass plate 64 and the board surface 31 of the game board P is more uniformly expanded than the diameter of the game ball. As a result, the game ball can be easily released from the bite of the ball.

  Thus, in a state where the ball biting is eliminated, the security plate S is closed and locked by the lock mechanism B2 as described above. At this time, in the security plate S, even if the distance between the displacement plate member 62 and the board surface 31 of the game board P is increased as described above, the relationship between the displacement plate member 62 and the holding frame 61 is Since this is the same as that at the original position of the displacement plate member 62, there is no room for fraud.

  After the ball engagement of the game ball is eliminated as described above, when the tool T is rotated counterclockwise as opposed to the above, the front-rear shaft 71c is rotated counterclockwise together with the bevel gear 71a, The bevel gear 71b rotates in the direction opposite to the arrow shown in FIG. 11 together with the vertical shaft 71d and the two bevel gears 72a and 73a under meshing with the bevel gear 71a.

  Accordingly, the bevel gear 72b is rotated in the direction opposite to the arrow shown in FIG. 11 together with the upper left and right direction shaft 72c and the upper cam members 74 while meshing with the bevel gear 72a. The bevel gear 73b rotates in the direction opposite to the arrow shown in FIG. 11 together with the lower left and right direction shaft 73c and the lower cam members 75 under meshing with the bevel gear 73a.

  As described above, when the upper cam members 74 are rotated in the direction opposite to the arrow shown in FIG. 11, the upper wall 63 c of the holding frame 63 of the displacement plate member 62 causes each arc-shaped cam surface portion of the upper cam members 74. The flat cam surface portion 74a is engaged with the disengagement from 74b. Further, as described above, when both the lower cam members 75 are rotated in the direction opposite to the illustrated arrow in FIG. 11, the lower wall 63 d of the holding frame 63 is moved from each arcuate cam surface portion 75 b of the both upper cam members 75. It engages with each planar cam surface part 75a with dissociation.

  Thus, when the upper wall 63c and the lower wall 63d of the holding frame 63 are engaged with the planar cam surface portions 74a of the upper cam members 74 and the planar cam surface portions 75 of the lower cam members 75, respectively, both upper guides are engaged. The pins 63g and the lower guide pins 63g are pulled rearward along the corresponding linear elongated hole portions 61e under the biasing force of the upper torsion springs 61g and the lower torsion springs 61g to the rear. Then, the holding frame 63 is displaced rearward.

  When the upper guide pins 63g and the lower guide pins 63g are engaged with the rear ends of the corresponding linear elongated holes 61e, the displacement plate member 62 returns to the original position. Along with this, the lock lever 92 returns to the original state shown in FIG. 19, but the security plate S remains locked. After the displacement plate member 62 returns to the original position as described above, the tool T is extracted from the tool insertion hole 18 of the front door D.

  If it is necessary to open the security plate S for some reason, the hall operator unlocks the locking device 17 of the front door D using the key K and opens the front door D. Is exposed to the front. Thereafter, the grip portion of the tool T is gripped, and the shaft portion Ta is coupled to the front-rear direction shaft 71 c of the rotation device B.

  When the tool T is further rotated clockwise as shown in FIGS. 20 and 21, the front-rear shaft 71 is similarly rotated clockwise, and the lock lever 92 is moved as shown in FIG. The security plate S is released from the locked state with respect to the frame H by being detached from the locking portion 41c of the locking member 41d. As a result, the security plate S can be opened from the frame H.

  In such a state, after the operator opens the security plate S and completes the necessary processing, the worker closes the security plate S, grips the grip portion of the tool T, and rotates the shaft portion Ta. It is connected to the longitudinal axis 71c of the device B. When the lock lever 92 is locked to the locking portion 41c of the locking member 41d by rotating the shaft tool T, the security plate S is locked to the frame H. Thereafter, the operator closes the front door D and locks the locking device 17 using the key K.

  As described above, in the first embodiment, the security plate S is supported between the gaming machine main body having the game board P and the front door D so as to be opened and closed.

  According to this, when the security board S is closed, no gap is formed between the security board S and the gaming machine main body. Therefore, even if a piano wire or the like can be inserted through the gap between the front door D and the gaming machine body, it is difficult to insert the piano wire or the like up to between the security board S and the gaming machine body. is there.

  For this reason, the said piano wire etc. cannot reach | attain the board surface 31 of the game board P, As a result, the above-mentioned fraudulent act can be prevented beforehand.

  Further, as described above, since the security plate S is locked to the frame H by the lock mechanism B2, the security plate S cannot be freely opened. For this reason, the security in the pachinko gaming machine is improved.

  Further, when the ball bite occurs, as described above, the displacement plate member 62 is displaced forward using the axial tool T while the security plate S is locked with the front door D closed. Since the distance between the displacement plate member 62 and the game board P is made larger than the diameter of the game ball, it becomes possible to eliminate the above-mentioned ball biting without opening the front door D and the security plate S. Convenient. At this time, since the security plate S remains locked as described above, the security of the pachinko gaming machine is improved in the same manner as before the elimination of the ball bite.

  In addition, the game board P includes a decorative part 35 projecting from the board surface 31, and the security board S includes each space G. For this reason, when the security plate S is closed, each decorative component 35 passes through the corresponding space G and protrudes forward of the security plate S. This means that the security plate S can be closed with respect to the frame H without being obstructed by the decorative part 35.

  Further, in pachinko gaming machines, generally, the production effect is enhanced by providing decorative parts such as electric decoration parts on the front door D. Here, in the pachinko gaming machine, although the game board P is regularly replaced, the front door D is normally maintained as it is without being replaced. With this, it is not possible to further enhance the effect of the decoration parts as a pachinko gaming machine in accordance with the replacement of the game board.

  For this reason, in this 1st Embodiment, since the decoration component 35 protrudes not on the front door D but on the board surface of the game board P, the effect by the decoration part as a pachinko gaming machine is produced every time the game board is replaced. Can be newly increased.

  In addition, although the shape of the security board S was a quadrangular shape in the above-described first embodiment, it may be configured with a shape (substantially circular shape) corresponding to the shape of the game area 32 on the board surface 31 of the game board P. The decorative part 35 may be arranged outside the security plate. In the first embodiment described above, the displacement plate member 62 of the security plate S is configured to be movable in the front-rear direction. However, the entire security plate S may be configured to be displaceable in the front-rear direction.

(Second Embodiment)
22 and 23 show the main part of a second embodiment of the pachinko gaming machine according to the present invention. In the second embodiment, a ball fall prevention device BC is additionally employed in the game board P of the pachinko gaming machine described in the first embodiment, and this ball fall prevention device BC is shown in FIG.

It is missing. Thereby, as shown in FIG. 23, the inclined surface 111c is formed in the lower front end corner portion of the thick portion 111a from the upper left side to the lower right side.

  The thin portion 111b is composed of a front half portion of the sliding body main body 111, and the thin portion 111b is integrally formed with the thick portion 111a so as to extend forward from the front end portion of the thick portion 111a. ing. The ball receiving rail 100a is connected to the extending end portion of the thin wall portion 111b at the central portion in the left-right direction of the rear edge portion and extends forward. Thereby, the upper side sliding body 110 supports the ball receiving rail 100a along the lower surface of the lower rail part 34a of the inner rail 34 on the upper surface thereof.

  The rod 112 extends rearward from the central rear end of the thick portion 111a of the sliding body main body 111, and this rod 112 is a recess 102a in the rear wall 102 (rear wall of the recess 103) of the casing 100c. (Described later) and an upper through hole 104a of a rear protruding wall 104 (described later) are slidably inserted in the axial direction.

  Here, the casing 100 c has a rear protruding wall 104, and the rear protruding wall 104 is integrally protruded rearward from the central portion in the left-right direction of the rear wall 102. The rear projecting wall 104 has upper and lower side insertion holes 104a and 104b, and the upper and lower side insertion holes 104a and 104b are formed on both the upper and lower sides of the rear projecting wall 104 and the rear projecting wall 104. The rear projecting wall 104 is formed with a space in the vertical direction so as to be positioned coaxially with the recesses 102a and 102b.

  Further, the upper through-hole portion 104a is formed by a predetermined value larger than the vertical width of the rod 112 so as to allow the vertical displacement of the rod 112 as will be described later. It should be noted that the upper and lower concave portions 102a and 102b are specifically arranged so that the rear wall 102 and the rod 112 of the upper sliding body 110 and the rod 122 (described later) of the lower sliding body 120 are coaxially positioned in the front-rear direction. Over the front part of the rear protruding wall 104, it is formed with an interval in the vertical direction.

  As shown in FIG. 23, the lower sliding body 120 includes a sliding body main body 121 and a rod 122 extending rearward from the rear end portion of the sliding body main body 121. The sliding body main body 121 has a flat plate shape, and the sliding body main body 121 is slidable in the front-rear direction between the bottom wall 101 of the casing 100c (the bottom wall of the recess 103) and the upper sliding body 110. It is accommodated in the recess 103 and extends toward the rising wall portion 61i provided on the outer holding frame 61 of the security plate S described in the first embodiment. The rising wall portion 61i is formed to protrude upward from the rear end portion of the lower wall 61d of the outer holding frame 61.

  In addition, the sliding body main body 121 is cut out at the upper rear end corner at an inclined portion in the longitudinal section as shown in FIG.

(See FIG. 25). When the lower sliding body 120 is pushed backward in such a state, the upper sliding body 110 is pushed upward along the inclined surface 121a of the lower sliding body 120 by the inclined surface 111c. While dissociating from the inclined surface 121a, the rod 112 is positioned along the upper inner surface of the upper through hole 104a of the rear protruding wall 104 of the casing 100 at the upper end surface (see FIG. 23).

  The rod 122 includes a rod portion 122a and a flange portion 122b. The rod portion 122a extends rearward from the central rear end portion of the sliding body main body 121, and is a lower concave portion of the rear wall 102 of the casing 100. 102b and the lower through hole 104b of the rear protruding wall 104 are coaxially inserted so as to be slidable in the front-rear direction. The flange portion 122b is coaxially fixed to the extending end portion of the rod portion 122a, and serves as a forward retaining portion for the lower sliding body 120.

  The coil spring 130 is fitted to the rod 112 of the upper sliding body 110, and the coil spring 130 is locked to the rear end portion of the thick portion 111a of the upper sliding body 110 at the front end portion thereof. At the rear end, it is inserted into the upper concave portion 102a of the rear wall 102 of the casing 100 and locked to the rear protruding wall 104 from its front side. Accordingly, the coil spring 130 urges the sliding body main body 111 of the upper sliding body 110 toward the front.

  The coil spring 140 is fitted to the rod 122 of the lower sliding body 120, and the coil spring 140 is engaged with the rear end portion of the sliding body main body 121 of the lower sliding body 120 at the front end portion thereof. At the rear end portion, it is inserted into the lower recess 102b of the rear wall 102 of the casing 100 and locked to the rear protruding wall 104 from its front side. Thereby, the coil spring 140 urges the sliding body main body 121 of the lower sliding body 120 toward the front. Other configurations are the same as those in the first embodiment.

  In the second embodiment configured as described above, when the glass plate 64 of the displacement plate member 62 of the security S is in the original position in the closed state of the security plate S as in the first embodiment, the ball is dropped. As shown in FIG. 23, the ball receiving rail 100a of the prevention device BC is urged forward by the coil spring 130 via the sliding body 111 of the upper sliding body 110 and engages with the glass plate 64 in the original position. ing.

  At this time, the upper sliding body 110 is located on the lower surface of the sliding body main body 121 of the lower sliding body 120 on the lower surface of the thick portion 111a, and the lower sliding body 120 is positioned on the sliding body main body 121. In addition, it engages with the rising wall portion 61i of the outer frame 61 of the security plate S from behind, and at the flange portion 122b, is located rearward from the rear protruding wall 104 of the casing 100 (see FIG. 23).

  In such a state, the upper sliding body 110 is moved by the sliding body main body 111 in accordance with the displacement of the displacement plate member 62 to the forward movement position of the glass plate 64 due to the occurrence of the ball biting as in the first embodiment. The ball receiving rail 100a slides forward under the biasing force of the coil spring 130, and the ball receiving rail 100a is pushed out by the upper sliding body 110 and displaced forward (see FIG. 24).

  This means that the ball receiving rail 100a is driven by the drive mechanism 100b so as to be displaced forward while following the advance of the glass plate 64 (see FIG. 27). At this time, the lower sliding body 120 is against the urging force of the coil spring 140 on the rear end opening outer peripheral portion of the lower through hole 104b of the rear protruding wall 104 of the casing 100 at the flange portion 122b. , Lock.

Accordingly, the distance between the glass plate 64 and the board surface 11 of the game board P increases as the glass plate 64 advances as described above, and the game ball falls from between the front edge of the inner rail 34 and the glass plate 64. Even if it becomes easy to do, the ball receiving rail 100 a is displaced forward while closing the gap between the glass plate 64 and the inner rail 34. Therefore, the game ball that falls due to the release of the ball bite is reliably received from below by the ball receiving rail 100a, and is discharged into the out port 36 without falling from between the security board S and the game board P. Then, after eliminating the ball engagement as described above, the glass plate 64 of the displacement plate member 62 of the security plate S is returned to the original position in the same manner as in the first embodiment, and then the security plate S is Open in the same manner as described in the first embodiment.

  Next, when the ball receiving rail 100a is pushed in the direction indicated by the arrow in FIG. 24, the ball receiving rail 100a is moved to the front edge of the inner rail 34 as shown in FIG. As shown in FIG. 25, the upper sliding body 110 is displaced downward along the inclined surface 121a of the lower sliding body 120 by its own weight, as shown in FIG. Engage with 121a.

  Along with this, the lower sliding body 120 is pushed forward, but since the flange 122a engages with the rearward projecting wall 104 of the casing 100 from the rear, the lower sliding body 120 is as shown in FIG. The engagement between the inclined surface 121a and the inclined surface 111c is maintained.

  Thereafter, when the security plate S is closed in the same manner as described in the first embodiment, the outer frame 61 is engaged with the lower sliding body 120 from its front side at the rising wall portion 61i. The engagement between the two inclined surfaces 111c and 121a is maintained well.

  As described above, in the second embodiment, when the ball biting is eliminated as described above, the falling game ball is reliably received by the ball receiving rail 100a by the ball drop preventing device BC, and the out mouth Since the ball is discharged into the space 36, it is possible to prevent the game ball from falling between the security board S and the game board P before the ball biting is eliminated. Other functions and effects are the same as those of the first embodiment.

  The drive mechanism 100b may be configured by an electric actuator such as an electromagnetic solenoid, and may be configured such that the ball receiving rail 100a is advanced when the security plate S is advanced and the ball receiving rail 100b is retracted when the security plate S is retracted.
