Not) is cut out. Further, a cutout portion (not shown) is formed in the corresponding inner surface portion of the right wall 61b of the outer frame 61 so as to open to the left side toward the cutout hole portion.

  Thus, the tool T configured in this way is operated as follows. That is, the tool T passes through the through hole 18 (see FIG. 6) of the front door D so that the protruding piece portion is positioned on the left side of the axis Tb, and the band of the inner frame 62 of the security plate S is formed. When the tool T is rotated in the clockwise direction as shown by an arcuate arrow in FIG. 9 in a state of being inserted into the insertion groove 62j, the protruding piece of the tool T It rotates clockwise around the axis of the shaft portion Tb in the cutout hole portion, enters the cutout portion of the right wall 61b from the cutout hole portion, and engages with the inner surface lower portion.

  Thereafter, when the tool T is further rotated in the clockwise direction, the tool T is moved downward with the lower part of the inner surface of the cutout portion of the right wall 61b at the protruding piece portion. Push toward. Accordingly, the right wall of the inner frame 62 is moved by the shaft portion Tb through the upper inner surface portion of the belt-like insertion groove portion 62j by the tool T while the notch portion is pushed against the inner surface lower portion by the projecting piece portion. 62a is pushed upward. For this reason, the inner frame 62 is guided by the guide pins 62i along the corresponding linear elongated hole portions 61f of the outer frame 61 and moves up.

  In the first embodiment configured as described above, in the pachinko gaming machine, as illustrated in FIG. 9, the front door D is in a state of closing the frame body H through the game board P together with the security S. Shall.

  In such a state, the inner frame 62 is seated on the lower wall 61d of the outer frame 61 by the lower wall 62d, and the security plate S is positioned in the rear portion of the inner frame 62 by the displacement plate member 63. is doing. This means that in the security plate S, the displacement plate member 63 is maintained at the original position (see FIGS. 4 and 9).

  At this time, each guide pin 62i of the inner frame 62 is in contact with the upper end portion of the corresponding straight elongated hole portion 61f of the outer frame 61 from below. Each guide pin 63g of the displacement plate member 63 is in contact with each rear upper end 62f from below in each corresponding inclined slot 62e of the inner frame 62.

  Further, the security plate S is locked to the frame body H by the lock lever mechanism 43. Here, the lock lever 43a of the lock lever mechanism 43 is urged by a torsion spring 43c, and is engaged with the hook portion 43d from above into the cutout portion 61e of the outer frame 61.

  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 63 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 63, the security plate S remains closed while being locked by the lock lever mechanism 43 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 tool T and inserts the shaft portion Tb into the tool insertion hole portion 18 (see FIG. 7) of the front door D as shown in FIG. The protruding piece portion of the shaft portion Tb is inserted into the belt-like insertion groove portion 62j of the right wall 62a of the inner frame 62 so as to be positioned on the left side of the shaft portion Tb.

  Thereafter, when the tool T is rotated clockwise as indicated by an arcuate arrow in FIG. 9, the protruding piece portion of the tool T is pivoted in the hollow portion of the right wall 61b. It rotates around the axis of the portion Tb in the clockwise direction, enters the cutout portion of the right wall 61b from the cut-out hole portion, and engages with the inner surface lower portion.

  At this stage, when the tool T is further rotated in the clockwise direction, the tool T, along with the rotation, the lower portion of the inner surface of the cutout portion of the right wall 61b at the protruding piece portion. Push downwards. Accordingly, the right wall of the inner frame 62 is moved by the shaft portion Tb through the upper inner surface portion of the belt-like insertion groove portion 62j by the tool T while the notch portion is pushed against the inner surface lower portion by the projecting piece portion. 62a is pushed upward. For this reason, the inner frame 62 is guided by the guide pins 62i along the corresponding linear elongated hole portions 61f of the outer frame 61 and moves up. In addition, in FIG.9 and FIG.10, the front door D is not shown for convenience.

  Along with the upward movement of the inner frame 62, in the security plate S, the displacement plate member 63 is moved by the guide pins 63g along the corresponding inclined long holes 62e of the inner frame 62 on the rear side thereof. Guided from the upper end 62f toward the front lower end 62g, it is displaced forward (ie, advanced). At this time, the displacement plate member 63 is restricted by the upper and lower walls 63c and 63d of the holding frame 63A so that it cannot move in the vertical direction between the upper and lower walls 61a and 61d of the outer frame 61. The member 63 advances while moving each guide pin 63 along the inclination direction of the corresponding inclined elongated hole portion 62e in accordance with the upward movement of the inner frame 62 described above.

  Thereafter, when each guide pin 63g reaches the intermediate position in the inclined direction of the corresponding inclined elongated hole 62e, the displacement plate member 63 reaches its forward position (see FIGS. 5 and 10).

  Thus, the displacement plate member 63 moves away from the board surface 31 of the game board P by the displacement plate member 63 being displaced from the original position to the forward movement position. This means that the distance between the displacement plate member 63 and the board surface 31 of the game board P is uniformly wider than the diameter of the game ball. As a result, the game ball can be easily released from the bite of the ball.

  As described above, in the state where the ball biting is eliminated, the security plate S is closed and locked by the lock lever mechanism 43 as described above. At this time, in the security plate S, even if the distance between the displacement plate member 63 and the board surface 31 of the game board P is increased as described above, the displacement plate member 63 and the inner frame 62 or the outer frame 61 Since the relationship between them is the same as in the original position of the displacement plate member 63, 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 projecting piece portion of the tool T It rotates in the counterclockwise direction around the axis of the shaft portion Tb within the portion, dissociates from the lower inner surface of the cutout portion of the right wall 61b, and returns to the inside of the cutout hole portion of the right wall 61b. Accordingly, the inner frame 62 moves downward while moving each guide pin 62i downward along the corresponding linear elongated hole portion 61f of the outer frame 61 under its own weight.

  With such a downward movement of the inner frame 62, in the security plate S, the displacement plate member 63 is moved along the corresponding inclined elongated hole 62 e of the inner frame 62 at each guide pin 63 g. It is guided toward the part 62f and is displaced rearward while moving upward relative to the downward movement of the inner frame 62. At this time, the displacement plate member 63 is restricted by the upper and lower walls 63c and 63d of the holding frame 63A so that it cannot move in the vertical direction between the upper and lower walls 61a and 61d of the outer frame 61. The member 63 is displaced rearward while moving each guide pin 63g along the inclination direction of each corresponding inclined elongated hole portion 62e in accordance with the downward movement of the inner frame 62 described above.

  Thereafter, when each guide pin 63g reaches the rear upper end 62f of each corresponding inclined elongated hole 62e, the displacement plate member 63 reaches its original position (see FIGS. 5 and 10). . Thereby, the space | interval of the displacement board member 63 and the board surface of the game board P returns to the original state. At this stage, since the ball biting has already been eliminated as described above, there is no particular problem. Further, after the displacement plate member 63 returns to the original position as described above, the tool T may be extracted from the tool insertion hole 18 of the front door D.

  If the security plate S needs to be opened for some reason, the front door D can be connected to the frame H by the locking device 17 by inserting the key K into the locking device 17 and performing a one-way turning operation. Freed from locking. At this time, the displacement plate member 63 is assumed to be in the original position.

  In this state, when the front door D is opened and then the operating rod 62k is gripped to move the inner frame 62 upward, the engaging protrusion 62l of the inner frame 62 is notched 61e of the outer frame 61. It enters from the lower side into the cutout part 61e of the upper wall 61a of the outer frame 61 and engages with the hook part 43d of the lock lever 43a from the lower side. Thereafter, the engagement protrusion 62l of the inner frame 62 tilts the lock lever 43a upward so as to push up the hook 43d against the torsion spring 43c.

  Accordingly, when the hook portion 43d of the lock lever 43a is disengaged upward from the cutout portion 61e of the upper wall 61a of the outer frame 61, the security plate S is released from the lock with the frame body H. In other words, the volume of the notch 61e is reduced as the engagement protrusion 62l is moved upward as the inner frame 62 is moved upward. However, while the inner frame 62 is moved upward within a predetermined range, The volume is not lost by the engaging protrusion 62l, and the security plate S is maintained in the locked state, while the volume is lost by the engaging protrusion 62l when the inner frame 62 moves up beyond a predetermined range. The locked state of the security plate S is released.

  Further, along with the upward movement of the inner frame 62 as described above, the guide pins 62 i of the inner frame 62 move upward along the corresponding linear elongated holes 61 f of the outer frame 61. Further, each guide pin 63g of the displacement plate member 63 moves from the rear upper end 62f to the front lower end 62g along the corresponding inclined elongated hole portion 62e of the inner frame 62, so that the displacement plate member 63 is advanced. Let

  As described above, after the security plate S is released from the lock with the frame H, the security plate S can be opened from the frame H with the inner frame 62 moved upward by the operation rod 62k ( (See FIG. 12). If the operation rod 62k is released after the security plate S is opened, the inner frame 62 moves downward due to its own weight, and the displacement plate member 63 returns to the original position.

  In such a state, when the security plate S is closed again, if the security plate S is pressed against the frame body H, the upper wall 61a of the outer frame 61 is locked to the lock lever 43a at the right end thereof. The hook portion 43d is closed while being pushed up against the torsion spring 43b. Along with this, the hook portion 43d of the lock lever 43a enters and engages with the cutout portion 61e of the outer frame 61 from above under the elasticity of the torsion spring 43b. As a result, the security plate S is locked again by the lock lever mechanism 43. Next, the front door D is closed, and then the front door D is locked by the key K via the locking device 17.

  When the security plate S is opened as described above, the tool T is inserted into the belt-like insertion groove 62j of the inner frame 62 in the same manner as described above and rotated clockwise without depending on the operation rod 62k. The inner frame 62 may be moved upward so as to be released from the lock by the lock lever mechanism 43 as described above. According to this, it becomes possible to eliminate the extra part of the operation rod 62k.

  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, when the security plate S is closed, the security plate S is locked to the frame H by the lock lever mechanism 43, so that the security plate S cannot be freely opened. For this reason, the security in the pachinko gaming machine is improved.

  When the ball bite occurs, as described above, the inner frame 62 is moved up using the tool T while the security plate S is locked with the front door D closed, and the displacement plate member 63 is moved. Since the distance between the displacement plate member 63 and the game board P is made larger than the diameter of the game ball, the ball biting is eliminated without opening the front door D and the security plate S. Is possible and 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 the first embodiment, the displacement plate member 63 is moved forward by moving the inner frame 62 upward and the lock mechanism 43 is operated. However, by moving the inner frame 63 downward rather than upward. The displacement plate member 63 can be moved forward and the lock mechanism 43 can be operated.

  In addition, the security plate S has a quadrangular shape in the above-described embodiment, but may have a shape (substantially circular shape) corresponding to the shape of the game area 32 on the board surface 31 of the game board P. 35 may be arranged outside the security plate. In the above-described embodiment, the displacement plate member 63 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 movable in the front-rear direction.

  In the first embodiment, the notch 61e is provided at the upper right end of the security plate S. However, the notch 61e is provided below the upper right end of the security plate S, and this notch 61e is provided. The lock lever 43a may be disposed so as to be engageable, and the operation similar to the operation according to the operation of the inner frame 62 as described above may be performed.

The rising wall portion 61g is formed to protrude upward from the rear end portion of the lower wall 61d of the outer frame 61.

  Further, 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. Thus, an inclined surface 121a is formed at the upper rear end corner of the sliding body 121 so as to be parallel to the inclined surface 111c of the upper sliding body 110 as shown in FIG.

  In the second embodiment, when the ball receiving rail 100a is positioned so as to overlap the front end portion of the lower rail portion 34a of the inner rail 34 from below at the front end portion thereof, the rod 112 of the upper sliding body 110 is The lower end surface of the upper sliding body 110 is located on the lower inner surface of the upper through hole 104 a of the rear protruding wall 104 of the casing 100, and the inclined surface 111 c of the upper sliding body 110 is related to the inclined surface 121 a of the lower sliding body 120. (See FIG. 16). 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. 14).

  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 63 of the security plate S is in the original position in the closed state of the security plate S as in the first embodiment, As shown in FIG. 14, the ball receiving rail 100a of the fall prevention device BC is urged forward by the coil spring 130 through the sliding body main body 111 of the upper sliding body 110, and the rear surface of the glass plate 64 in the original position is Abutting from the side. 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. The abutting wall 61g of the outer frame 61 of the security plate S is in contact with the rear wall 61g from the rear, and at the flange 122b, is positioned rearward from the rear protruding wall 104 of the casing 100 (see FIG. 14).

  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 63 to the advance position of the glass plate 64 due to the occurrence of the ball biting as in the first embodiment. While sliding forward, the ball receiving rail 100a is pushed forward by the upper sliding body 110 and displaced forward (see FIG. 15).

  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. 18). 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 the state which is easy to do, the ball receiving rail 100a is displaced forward following the glass plate 64 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. To go.

  Thereafter, after the ball bite is eliminated as described above, the glass plate 64 of the displacement plate 63 of the security plate S is returned to the original position as in the first embodiment, and then the security plate S is moved to the first embodiment. Open as described in the form.

  Next, when the ball receiving rail 100a is pushed in the direction indicated by the arrow in FIG. 15, the ball receiving rail 100a is moved to the front edge of the inner rail 34 at its front edge as shown in FIG. When the upper sliding body 110 is displaced to the overlapping position, the inclined surface 121a is displaced downward along the inclined surface 121a of the lower sliding body 120 at the inclined surface 111c by its own weight as shown in FIG. Engage with.

  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.

  After that, when the security plate S is closed in the same manner as described in the first embodiment, the outer frame 61 abuts the lower sliding body 120 from the front side with the rising wall 61g, so Good engagement between the inclined surfaces 111c and 121a is maintained.
