  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.

  Also, in pachinko gaming machines, generally, the production effect is enhanced by providing decorative parts such as electric parts on the front door. Here, in the pachinko gaming machine, although the game board is periodically replaced, the front door is usually 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.

  Therefore, in order to cope with the above, the present invention supports a security board provided with a decorative part so as to be openable and closable between the front doors on the main body of the gaming machine, and the configuration of the security board includes a ball bit. The purpose is to provide a pachinko gaming machine that can eliminate ball chewing and prevent fraud.

  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 movable 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 movable frame 62 is moved by the shaft Tb through the upper inner surface of the belt-like insertion groove 62j by the shaft Tb while the tool T pushes the notched portion against the lower surface of the inner surface by the protruding piece. 62a is pushed upward. For this reason, the movable frame 62 is guided by the guide pins 62i along the corresponding linear elongated hole portions 61f of the fixed frame 61 and moves upward. In addition, in FIG.9 and FIG.10, the front door D is not shown for convenience.

  With such upward movement of the movable 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 movable 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 fixed frame 61. The member 63 moves forward 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 movable 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 wide as described above, the displacement plate member 63 and the movable frame 62 or the fixed 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. Along with this, the movable frame 62 moves downward while moving each guide pin 62i downward along the corresponding linear elongated hole portion 61f of the fixed frame 61 under its own weight.

  With such downward movement of the movable frame 62, in the security plate S, the displacement plate member 63 is connected to each upper end of the rear side along the corresponding inclined slot 62e of the movable frame 62 at each guide pin 63g. It is guided toward the part 62f and is displaced rearward while moving upward relative to the downward movement of the movable 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 fixed frame 61. The member 63 is displaced rearward while moving each guide pin 63g along the inclination direction of the corresponding inclined elongated hole portion 62e in accordance with the downward movement of the movable 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 movable frame 62 upward, the engaging protrusion 62l of the movable frame 62 becomes the notch 61e of the fixed frame 61. It enters from below into the cutout portion 61e of the upper wall 61a of the fixed frame 61 and engages with the hook portion 43d of the lock lever 43a. Thereafter, the engaging protrusion 62l of the movable 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 fixed 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 decreases as the engagement protrusion 62l moves upward as the movable frame 62 moves upward, but while the movable frame 62 moves up 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. On the other hand, when the movable frame 62 moves up beyond a predetermined range, the volume is lost by the engaging protrusion 62l. The locked state of the security plate S is released.

  Further, with the upward movement of the movable frame 62 as described above, each guide pin 62 i of the movable frame 62 moves upward along the corresponding linear elongated hole portion 61 f of the fixed 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 62e of the movable frame 62, thereby moving the displacement plate member 63 forward. 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 movable frame 62 moved up by the operation rod 62k ( (See FIG. 12). If the operation rod 62k is released after the security plate S is opened, the movable frame 62 is moved down by 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 fixed 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 fixed 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.

  Note that when opening the security plate S as described above, the tool T is inserted into the belt-like insertion groove 62j of the movable frame 62 in the same manner as described above and rotated clockwise without depending on the operation rod 62k. The movable 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.

  In the first embodiment, the security plate S is configured to include the decorative members 60a as described above. The basis for such a configuration will be described.

  In pachinko gaming machines, in general, the production effect is enhanced by providing decorative parts such as electric parts on the front door. Here, in the pachinko gaming machine, although the game board is periodically replaced, the front door is usually 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 each decoration component 60a is protrudingly provided in the security board S instead of the front door D, if the security board S is replaced | exchanged with the game board P, for every exchange, It is possible to newly enhance the effect of the decoration parts as a pachinko machine.

  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 movable 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 the first embodiment, as described above, each decorative component 60a is provided in the security board S. Therefore, in combination with the above-described operational effects, the effect produced by each decorative component 60a is changed to the game board. It can be increased each time the P and the security plate S are replaced.

  In the first embodiment, the displacement plate member 63 is moved forward by moving the movable frame 62 and the lock mechanism 43 is operated. However, by moving the movable frame 63 downward instead of upward. The displacement plate member 63 can be moved forward and the lock mechanism 43 can be operated.

  Moreover, although the shape of the security plate S is a quadrangular shape in the first embodiment described above, 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. Each decorative part 60a may be attached to the fixed frame of the security plate from the outside. In the first embodiment described above, 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 same operation as that according to the operation of the movable frame 62 as described above may be performed.

It is supported at the middle part in the direction.

  Here, the cam surfaces of the left and right side cam members 175 are configured similarly to the cam surfaces of the left and right side cam members 174, and the cam surfaces of the left and right side cam members 175 are shown in FIGS. As shown in FIG. 33, a planar cam surface portion 175a and an arc surface cam surface portion 175b corresponding to the planar cam surface portion 174a and the arc surface cam surface portion 174b, respectively, are provided.

  Thus, as will be described later, the planar cam surface portion 175a is formed in a straight vertical section so as to displace the glass plate 164 of the displacement plate member 162 from its original position to its forward position (or from its forward position to its original position). ing. Thereby, each of the left and right cam members 175 is engaged with the lower wall 163c of the holding frame 163 by the cam surface portion 175a, and the rotation position shown in FIG. 31 (hereinafter referred to as the lower original rotation angle position). 32) to the rotation position (also referred to as the lower forward rotation angle position) shown in FIGS. 32 and 33, and the counterclockwise direction from the advance rotation angle position to the original rotation angle position.

  The arcuate cam surface portion 175b has an arcuate vertical cross section that is outwardly convex with the center of the shaft hole portion of each of the left and right cam members 175 (the axis of the left and right direction shaft 173c) as the center of the cam surface portion 175a. It is formed clockwise from the clockwise end. Thereby, each of the left and right side cam members 175 maintains the glass plate 164 of the displacement plate member 162 at the forward position under the engagement of the arcuate cam surface portion 175b with the lower wall 163d of the holding frame 163.

  The lock mechanism B2 includes a bevel gear 191 and a lock lever 192 as shown in FIG. The bevel gear 191 is pivotally supported by the shaft at the intermediate portion in the vertical direction of the right wall 161b of the holding frame 161 from the left surface via the bearing 193, and the bevel gear 191 is supported by the tooth portion. Thus, it is positioned so as to be coaxially opposed to the tooth portion of the bevel gear 171a and meshes with the bevel gear 171b.

  The lock lever 192 is coaxially supported by the shaft of the bevel gear 191 at its base end, and the lock lever 192 extends from the base end so as to be orthogonal to the shaft of the bevel gear 191. Thus, it can be locked to a locking member 41c provided on the right wall 41b of the frame H. In the third embodiment, the locking member 41c is attached to the front surface of the right wall 41b of the frame H at both legs, and the locking member 41c is connected to the U-shaped locking portion 41d. The U-shaped projections project forward from the opposing ends of the two leg portions.

  Thus, the lock lever 192 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. 26, and in FIG. As shown, it is dissociated 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 Sa) by locking the locking member 92 of the locking lever 92 in the position shown in FIG. 26 into the U-shaped locking portion 41d. ) 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 192 that rotates counterclockwise as shown in FIG. means.

  As shown in any of FIGS. 22 to 25, the displacement plate member 162 includes a regular octagonal holding frame 163 and a regular octagonal glass plate 164, and the glass plate 164 includes the holding frame 163. Is fitted into the regular octagonal hollow portion. The holding frame 163 is formed in a regular octagonal shape as described above by the right wall 163a, the left wall 163b, the upper wall 163c, the lower wall 163d, and the inclined walls 163e.

  As shown in FIG. 22, the displacement plate member 162 configured as described above is arranged in the following manner between the upper wall 161a and the lower wall 161d of the holding frame 161 with respect to the upper wall 161a and the lower wall 161d. It is assembled in the rectangular hollow portion of the holding frame 161 so that it can be displaced in the direction.

  Here, the displacement plate member 162 has two sets of both guide pins 163g (see FIG. 25) on both the upper and lower sides, and the upper guide pins 163g are respectively the holding frame of the upper wall 163c of the holding frame 163. The upper wall 161a of the upper wall 161a protrudes upward from the corresponding portion of the corresponding linear elongated hole portion 161e. Thus, the upper guide pins 163g are inserted into the corresponding linear elongated holes 161e so as to be relatively displaceable in the longitudinal direction (front-rear direction). The upper guide pins 163g are press-fitted into the respective press-fitting hole portions 163f formed in the corresponding portions of the upper wall 163a with respect to the two linear elongated holes 161e of the upper wall 161a and protrude upward.

  The lower guide pins 163g are respectively projected downward from the corresponding portions of the lower wall 163d of the holding frame 163 with respect to the corresponding linear elongated holes 161e of the lower wall 161d of the holding frame 161, respectively. It is inserted into the corresponding linear slot 161e so as to be capable of relative displacement in the longitudinal direction (front-rear direction). The lower guide pins 163g are press-fitted into the respective press-fitting hole portions formed at the respective portions of the lower wall 163d facing the linear elongated holes 161e of the upper and lower walls 161d and protrude downward. Yes.

  Thereby, as described above, the displacement plate member 162 is displaced in the front-rear direction along the straight long holes 161e with respect to the upper and lower walls 161a and 161d between the upper and lower walls 161a and 161d in the holding frame 161. It is possible.

  In the third embodiment, as will be described later, the position at which the ball of the game ball can be eliminated between the glass plate 164 and the board surface 31 of the game board P (displacement board member 162) as the displacement plate member 162 is displaced forward. Each of the advancing positions at which the left and right upper guide pins 163g reach within the left and right upper linear elongated holes 161e and the predetermined front-rear direction intermediate portion of the left and right upper linear elongated holes 161e. At the same time, the respective forward positions where the left and right lower guide pins 163g reach within the left and right lower linear elongated holes 161e correspond to the predetermined front-rear direction intermediate portions of the left and right lower linear elongated holes 161e. It is set to. Therefore, in order to disengage the tool T from the locking with the locking member 141c as described above, the left and right upper guide pins 163g are moved to the left and right upper straight lines by rotating the tool T in the further clockwise direction as described above. The left and right lower guide pins 163g are moved to the rear end portions of the left and right lower straight elongated hole portions 161e while moving to the rear end portions of the long hole portions 161e.

  Further, by assembling the displacement plate member 162 in the holding frame 161 as described above, a triangular space is formed between each corner of the holding frame 161 and the corresponding inclined wall 163e of the holding frame 163. As illustrated in FIG. 22, Ga is formed, and each void Ga can project the decorative component 160a having a right triangular prism shape via the vertical axis 71d and the horizontal axes 72c and 73c, as will be described later. Is formed.

  Each decorative part 160a is supported at each of the upper, lower, left and right corners of the holding frame 161 at the rear end thereof, and each decorative part 60a passes forward through each corresponding space Ga to the front of the front door D. It protrudes so as to be able to be inserted into each corresponding through hole 16.

  Here, among the decorative parts 160a, the decorative part 160a (the upper left corner side decorative part 160a) located at the upper left corner of the holding frame 161 is a void Ga formed at the upper left corner of the holding frame 161. Out of (the upper left corner side space Ga), it passes through the lower part of the left-right direction shaft 172c and protrudes forward. The decorative part 160a located at the lower left corner of the holding frame 161 is a portion above the left and right axis 173c in the void Ga (lower left corner side void Ga) formed at the lower left corner of the holding frame 161. Project forward.

  The decorative part 160a (upper right corner side decorative part 160a) located at the upper right corner of the holding frame 161 is a space Ga (upper right corner side space Ga) formed at the upper right corner of the holding frame 161. Of these, it passes through a portion inside the intersection of the left-right axis 172c and the vertical axis 171d and protrudes forward. The decorative part 160a (lower right corner side decorative part 160a) located at the lower right corner of the holding frame 161 is a void Ga (lower right corner side void Ga formed in the lower right corner of the holding frame 161). ) Through the portion inside the intersection of the left and right direction axis 173c and the up and down direction axis 171d and protrudes forward. In addition, each through-hole part 16 of the front door D is formed so that it may not interfere with each decorative component 160a.

  In the third 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 body H via the game board P together with the security Sa.

  In such a state, as shown in FIG. 28, the upper cam members 174 of the rotating device B are. Each of the planar cam surface portions 174a engages with the rear surface of the upper wall 163c of the holding frame 163, and the upper guide pins 163g are respectively connected to the corresponding upper coiled torsion as shown in FIGS. The spring force of the spring 161g is held in a state of being pressed against the rear end portion of each corresponding linear long hole portion 161e of the upper wall 161a. Further, as shown in FIG. 31, the lower cam members 175 are engaged with the rear surface of the lower wall 163d of the holding frame 163 at the flat cam surface portion 175a, and the lower guide pins 163g are respectively The corresponding lower coiled torsion spring 161g is held in a state of being pressed against the rear end portion of each corresponding linear elongated hole portion 161e of the lower wall 161a by the spring force. As a result, the displacement plate member 162 is held in the original position as shown in FIG.

  Further, as shown in FIG. 34, the lock mechanism B2 locks the security plate Sa to the frame H by locking the lock plate 192 to the locking portion 41c of the locking member 41d of the frame H. Yes.

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

  Therefore, even if a gap is generated between the front door D and the gaming machine main body, no gap is generated between the security plate Sa and the gaming machine main body as described above. In such a state, the security board Sa closes the game board P.

  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 plate Sa, it is difficult to allow a piano wire or the like to enter between the security plate Sa and the gaming 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 162 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 162, the security plate Sa remains closed in the locked state by the lock mechanism B2 as described above. Therefore, it cannot be opened even if the front door D is opened to open the security plate Sa.

  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 | shaft 171c.

  When the shaft tool T is rotated clockwise as shown by an arc-shaped arrow in FIG. 26 against the urging force of each torsion spring 161g, the longitudinal shaft 171c is pivoted in the longitudinal shaft mechanism portion Ba. The bevel gear 171a is rotated in the same direction as the longitudinal axis 171c.

  Along with this, the bevel gear 171b is rotated by the bevel gear 171a while meshing with the bevel gear 171a, and the vertical shaft 171d of the rotation transmission mechanism portion Bb is moved together with the both bevel gears 172a and 173a. It rotates in the same direction as the bevel gear 171b (see the arrow direction shown in FIG. 26).

  When the bevel gear 172a is rotated as described above, the bevel gear 172b of the upper rotation cam mechanism Bc is rotated by the bevel gear 172a while meshing with the bevel gear 172a, so that the upper left-right shaft Together with the 172c and the upper cam members 174, it rotates in the direction of the arrow shown in FIG. When the bevel gear 173a is rotated as described above, the bevel gear 173b of the lower rotation cam mechanism Bd is rotated by the bevel gear 173a while being engaged with the bevel gear 173a. Together with the side left-right direction shaft 173c and the lower cam members 175, it rotates in the direction of the arrow shown in FIG.

  When the upper cam members 174 are rotated as described above, the upper wall 163c of the holding frame 163 of the displacement plate member 162 is pushed forward by the upper cam members 174 at the respective planar cam surface portions 174a. (See FIG. 28). At this time, the upper guide pins 163g move forward along the corresponding linear elongated holes 161e against the urging forces of the upper torsion springs 161g. When the upper cam members 175 rotate as described above, the lower wall 163d of the holding frame 163 is pushed forward by the upper cam members 175 at the respective planar cam surface portions 175a (see FIG. 31). At this time, the lower guide pins 163g move forward along the corresponding linear elongated holes 161e against the urging forces of the lower torsion springs 161g. Thus, the displacement plate member 162 is displaced forward from the original position in the holding frame 161.

  In such a state, the upper cam members 174 have each engaged with the rear surface of the upper wall 163c of the holding frame 163 by the respective planar cam surface portions 174a, and as shown in FIGS. The arc-shaped cam surface portion 175b engages with the rear surface of the upper wall 163c of the holding frame 163, and both the lower cam members 175 engage with the rear surface of the lower wall 163d of the holding frame 163 by the respective planar cam surface portions 175a. 32 and 33, each arcuate cam surface portion 175b engages with the rear surface of the lower wall 163d of the holding frame 163 as shown in FIGS. At this time, the upper guide pins 163g and the lower guide pins 163g engage with the front end portions of the corresponding linear elongated holes 161e of the holding frame 161, respectively.

  This means that the displacement plate member 162 is displaced to the above-mentioned advance position, and the distance between the glass plate 164 and the board surface 31 of the game board P is uniformly expanded beyond 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 has been eliminated, the security plate Sa is closed and locked by the lock mechanism B2 as described above. At this time, in the security plate Sa, even if the distance between the displacement plate member 162 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 161 is as follows. Since it is the same as that at the original position of the displacement plate member 162, 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, the front / rear direction shaft 171c rotates counterclockwise together with the bevel gear 171a, The bevel gear 171b rotates together with the bevel gear 171a in the direction opposite to the arrow shown in FIG. 26 together with the vertical shaft 171d and the two bevel gears 172a and 173a.

  Along with this, the bevel gear 172b rotates in the direction opposite to the arrow shown in FIG. 26 together with the upper left and right shaft 172c and the upper cam members 174 while meshing with the bevel gear 172a. The bevel gear 173b rotates in the direction opposite to the arrow shown in FIG. 26 together with the lower left and right direction shaft 173c and the lower cam members 175 while meshing with the bevel gear 173a.

  As described above, when the upper cam members 174 are rotated in the direction opposite to the arrow shown in FIG. 26, the upper wall 163c of the holding frame 163 of the displacement plate member 162 is changed to each arc-shaped cam surface portion of the upper cam members 174. With the disengagement from 174b, each planar cam surface portion 174a is engaged. Further, as described above, when both the lower cam members 175 are rotated in the direction opposite to the arrow shown in FIG. 26, the lower wall 163d of the holding frame 163 is moved from each arcuate cam surface portion 175b of the both upper cam members 175. It engages with each planar cam surface part 175a with dissociation.

  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 Sa is locked to the frame H by the lock mechanism B2, the security plate Sa 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 162 is displaced forward using the shaft tool T while the security plate Sa is locked with the front door D closed. Thus, since the interval between the displacement plate member 162 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 Sa. Convenient. At this time, since the security plate Sa remains locked as described above, the security of the pachinko gaming machine is improved in the same manner as before the ball bite is eliminated.

  Further, in the third embodiment, as described above, each decorative component 160a is provided on the security plate Sa. Therefore, in combination with the above-described operational effects, the effect produced by each decorative component 160a is changed to the game board. It can be increased every time the P and the security plate Sa are replaced.

  The shape of the security plate Sa is a quadrangular shape in the above-described third embodiment, but 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 160a may be arranged outside the security plate.

The lock lever 274 is coaxially supported on the pinion shaft 271b of the pinion 271 at the base end portion, and the lock lever 274 extends from the base end portion so as to be orthogonal to the pinion shaft 271b. Thus, it can be locked to a locking member 41c provided on the right wall 41b of the frame H. In the fifth embodiment, as in the first embodiment, the locking member 41c is attached to the front surface of the right wall 41b of the frame H at both legs, and the locking member 41c is The U-shaped locking portion 41d protrudes forward in a U-shape from the opposing end portions of the both leg portions.

  Thus, the lock lever 274 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. 45. As indicated by 47, it is disengaged from the locking portion 41d of the locking member 41c by further clockwise rotation.

  This is because the locking mechanism RP2 is configured so that the holding frame 263 (in other words, the security plate Sb) is locked by locking the locking member 41c of the locking lever 274 in the position shown in FIG. ) Is locked to the frame H, and the lock is released by disengaging the locking member 41c from the U-shaped locking portion 41d of the locking lever 274 which further rotates clockwise as shown in FIGS. It means to do.

  As shown in any of FIGS. 39 to 44, the displacement plate member 262 includes a regular octagonal holding frame 263 and a regular octagonal glass plate 264, and the glass plate 264 includes the holding frame 263. Is fitted into the regular octagonal hollow portion. The holding frame 263 is formed in a regular octagonal shape as described above by the right wall 263a, the left wall 263b, the upper wall 263c, the lower wall 263d, and the inclined walls 263e.

  As shown in FIG. 39, the displacement plate member 262 configured as described above is arranged in the following manner between the upper wall 261a and the lower wall 261d of the holding frame 261 with respect to the upper wall 261a and the lower wall 261d. It is assembled in the rectangular hollow portion of the holding frame 261 so that it can be displaced in the direction.

  Here, the displacement plate member 262 has left and right upper and lower left and right guide pins 263g (see FIG. 42), and the left and right upper guide pins 263g are respectively held on the upper wall 263c of the holding frame 263. Each of the upper walls 261a of the frame 261 protrudes upward from each corresponding portion with respect to each corresponding linear elongated hole portion 261e. Accordingly, the left and right upper guide pins 263g are inserted into the corresponding linear elongated holes 261e so as to be relatively displaceable in the longitudinal direction (front-rear direction). The left and right upper guide pins 263g are press-fitted into the respective press-fitting hole portions 263f formed in the corresponding portions of the upper wall 263a with respect to the two linear elongated holes 261e of the upper wall 261a and protrude upward.

  The left and right lower guide pins 263g respectively protrude downward from the corresponding portions of the lower wall 263d of the holding frame 263 with respect to the corresponding linear elongated holes 261e of the lower wall 261d of the holding frame 261. It is inserted into the corresponding linear elongated hole portion 261e so as to be capable of relative displacement in the longitudinal direction (front-rear direction). The left and right lower guide pins 263g 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 261e of the upper and lower walls 261d and protrude downward. Yes.

  Further, as shown in any of FIGS. 51 to 56, the holding frame 263 has an upper protruding wall 263i and a lower protruding wall 263k, and the upper protruding wall 263i is an upper guide wall of the upper guide member RPc. The upper wall 263c of the holding frame 263 is integrally formed so as to protrude rearward so as to face the 290A. Here, the upper protruding wall 263i is formed as an inclined surface 263h parallel to the inclined surface 291 of the upper guide wall 290A at its protruding end surface.

  Thus, the upper protruding wall 263i is pushed forward by the inclined surface 291 in accordance with the downward movement of the upper guide wall 290A under the sliding contact with the inclined surface 291 of the upper guide wall 290A at the inclined surface 263h. Moved. Further, the upper projecting wall 263i is pulled by the left and right upper torsion springs 261g while being slidably contacted with the inclined surface 291 of the upper guide wall 290A by the inclined surface 263h while pushing the inclined surface 291 backward. The upper guide wall 290A is moved upward.

  Further, the lower protruding wall 263k is integrally formed to protrude rearward from the rear upper end of the lower wall 263d of the holding frame 263 so as to face the lower guide wall 290B of the lower guide member RPd. Here, the lower protruding wall 263k is formed as an inclined surface 263j parallel to the inclined surface 292 of the lower guide wall 290B at the protruding end surface. As a result, the lower protruding wall 263k is moved by the inclined surface 292 in accordance with the upward movement of the lower guide wall 290B under sliding contact with the inclined surface 292 of the lower guide wall 290B at the inclined surface 263j. It is pushed forward. Further, the lower protruding wall 263k is pulled by the left and right lower torsion springs 261g while sliding with the inclined surface 292 of the lower guide wall 290B at the inclined surface 263j to push the inclined surface 292 backward. The lower guide wall 290B is moved downward while moving.

  As a result, the displacement plate member 262 is displaced in the front-rear direction along the linear long hole portions 261e with respect to the upper and lower walls 261a and 261d between the upper and lower walls 261a and 261d in the holding frame 261 as described above. It is possible.

  In the fifth embodiment, as will be described later, the position at which the ball engagement of the game ball between the glass plate 264 and the board surface 31 of the game board P can be eliminated with the displacement of the displacement board member 262 (displacement plate member 262). Each of the advancing positions where the left and right upper guide pins 263g reach within the left and right upper linear elongated holes 261e and the predetermined front-rear direction intermediate portion of the left and right upper linear elongated holes 261e. At the same time, the respective forward positions where the left and right lower guide pins 263g reach within the left and right lower linear elongated holes 261e correspond to the predetermined intermediate portions in the front and rear direction of the left and right lower linear elongated holes 261e. 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 263g are moved to the respective rear end portions of the left and right lower linear long hole portions 261e while being moved to the respective rear end portions of the long hole portion 261e.

Further, as described above, the displacement plate member 262 is assembled into the holding frame 261, so that a triangular space is provided between each corner of the holding frame 261 and the corresponding inclined wall 163e of the holding frame 263. Gb is formed, and each void Gb, as will be described later,
As illustrated in FIG. 43, the decorative component 260a having a right triangular prism shape can be protruded through the vertical axis 272b and the horizontal axes 282a and 272c.

  Each decorative component 260a is supported at each of the upper, lower, left and right corners of the holding frame 261 at its rear end, and each decorative component 260a passes forward through each corresponding space Gb and forwards the front door D. It protrudes so as to be able to be inserted into each corresponding through hole 16.

  Here, among the decorative parts 260a, the decorative part 260a (the upper left corner side decorative part 260a) positioned at the upper left corner of the holding frame 261 is a void Gb formed at the upper left corner of the holding frame 261. Out of (the upper left corner side space Gb), it passes through the lower part of the left and right direction axis 282a and protrudes forward. The decorative component 260a positioned at the lower left corner of the holding frame 261 is a portion above the left and right axis 272c in the space Gb (lower left corner side space Gb) formed at the lower left corner of the holding frame 261. Project forward.

  The decorative component 260a (upper right corner side decorative component 260a) located at the upper right corner of the holding frame 261 is a space Gb (upper right corner side space Gb) formed in the upper right corner of the holding frame 261. Of these, it passes forward through a portion inside the intersection of the left and right axis 282a and the vertical axis 272b and protrudes forward. Further, a decorative part 260a (lower right corner side decorative part 260a) positioned at the lower right corner of the holding frame 261 is a space Gb (lower right corner side space Gb) formed at the lower right corner of the holding frame 261. ) And protrudes forward through a portion inside the intersection of the left and right axis 272c and the vertical axis 272b. In addition, each through-hole part 16 of the front door D is formed so that it may not interfere with each decoration component 260a.

  In the fifth 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 body H via the game board P together with the security Sb.

  In such a state, as shown in FIG. 51, the upper guide wall 290A of the rack and pinion device RP is inclined below the inclined surface 291 and the inclined surface 263h of the upper protruding wall 263i of the holding frame 263 of the displacement plate member 262. 40 and 41, the left and right upper guide pins 263g are respectively formed on the left and right linear elongated holes 261e of the upper wall 261a of the holding frame 261 by the respective spring forces of the left and right upper torsion springs 261g. It is pressed against the rear end.

  Further, as shown in FIG. 54, the lower guide wall 290B of the rack and pinion device RP contacts the inclined surface 263j of the lower protruding wall 263k of the holding frame 263 at the upper part of the inclined surface 292, so The side guide pins 263g are pressed against the rear ends of the left and right linear elongated holes 261e of the upper wall 261d of the holding frame 261 by the spring force of the left and right lower torsion springs 261g, respectively.

  According to the above, the displacement plate member 262 is held in its original position as shown in FIGS. 37, 40, and 41. At this time, the pinion 281 meshes with the upper part of the upper tooth part 272h of the rack 272 and the lower part of the tooth part 282c of the rack 282, as shown in FIG.

  Further, as shown in FIG. 45, the lock mechanism RP2 is locked by the lock lever 274 to the locking portion 41c of the locking member 41d to lock the security plate Sb to the frame H of the gaming machine body. Yes.

  In such a state, the security board Sb closes the gaming machine main body via the game board P. For this reason, a slight gap does not occur between the security plate Sb 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 Sb 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 allow a piano wire or the like to enter between the security board Sb and the gaming 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 262 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 Sb remains closed while being locked by the lock mechanism RP2 as described above. Therefore, even if the front door D is opened to open the security plate Sb, it cannot be opened.

  Therefore, for example, a hole operator 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 drive mechanism member RPa. Connected to the directional shaft 273.

  When the shaft-shaped tool T is rotated clockwise as shown by an arc-shaped arrow in FIG. 45 against the biasing force of each torsion spring 261g, the front-rear shaft 273 is moved to the shaft-shaped tool in the drive mechanism member RPa. The pinion 271 rotates in the same direction as the longitudinal axis 273.

  When the pinion 271 rotates in this way, the rack 272 moves upward as shown in FIG. 46 while meshing with the pinion 271 of the lower tooth portion 272a. At this time, the upper and lower guide pins 272f and 272g move upward along the long hole portions 261m and 261v of the pin support plates 261k and 261u of the holding frame 261, whereby the rack 272 moves upward.

  Further, when the rack 272 moves upward as described above, the pinion 281 rotates counterclockwise (in the direction of the arrow in the figure) as shown in FIG. 48, and the vertical axis 282b of the rack 282 is moved in FIG. As shown, the tooth portion 282c moves downward as the pinion 281 rotates counterclockwise while meshing with the pinion 281. This means that the upper guide member RPb moves downward together with the upper left and right direction shaft 282a and the upper guide wall 290A. At this time, the left and right upper guide pins 282d and 282e move downward along the long hole portions 261p and 261r of the pin support plates 261o and 261q of the holding frame 261, whereby the rack 282 moves downward.

  Further, when the rack 272 moves upward as described above, the lower guide member RPd moves together with the rack 272 because the lower guide member RPd is integrated with the rack 272. This means that the lower guide member RPd moves upward together with the lower left / right axis 272c and the lower guide wall 290B.

  As described above, when the upper guide member RPb moves downward and the lower guide member RPd moves upward, the upper guide member RPb and the lower guide member RPd move in a direction approaching each other. In other words, when the upper guide wall 290A moves downward and the lower guide wall 290B moves upward, the upper guide wall 290A and the lower guide wall 290B move in a direction approaching each other.

  Accordingly, the upper guide wall 290A pushes the inclined surface 263h forward while sliding on the inclined surface 263h of the upper wall 263c of the holding frame 263 with the inclined surface 291 under the downward movement. At the same time, the lower guide wall 290B pushes the inclined surface 263j forward while sliding on the inclined surface 263j of the lower wall 263d of the holding frame 263 on the inclined surface 292 under the upward movement. To do.

  Here, when the upper wall 263c and the lower wall 263d of the holding frame 263 are moved downward and upward as described above, the left and right upper guide pins 263g and the left and right lower guide pins 263g of the holding frame 263 are respectively left and right upper. Along the long hole portion 261e and the left and right lower long hole portions 261e, against each biasing force of the left and right upper side torsion springs 261g and left and right lower side torsion springs 261g, along the corresponding long hole portions 261e, from the rear end portion, Move toward the middle part in the front-rear direction.

  As described above, the holding frame 263 is guided forward by the upper guide wall 290A and the lower guide wall 290B by the upper wall 263c and the lower wall 263d, and is guided forward, as shown in FIGS. As indicated at 53, it moves forward. This is because the displacement plate member 262 is displaced from the original position to the advance position in the holding frame 261, and the distance between the glass plate 264 and the board surface 31 of the game board P is set to be smaller than the diameter of the game ball. It means expanding. As a result, the game ball can be easily released from the bite of the ball.

  On the other hand, in the lock mechanism RP2, when the shaft tool T is rotated as described above and the displacement plate member 262 is displaced to the advanced position, the lock lever 274 is still locked as shown in FIG. It is maintained in a state of being locked to the locking portion 41c of the member 41d.

  Accordingly, in a state where the ball biting is eliminated, the security plate Sb is locked by the lock mechanism RP2 while being closed. At this time, in the security plate Sb, even if the distance between the displacement plate member 262 and the board surface 31 of the game board P is increased as described above, the relationship between the displacement plate member 262 and the holding frame 261 is as follows. Since this is the same as when the displacement plate member 262 is at the original position, there is no room for fraud.

  After canceling the ball engagement of the game ball as described above, when the tool T is rotated counterclockwise (opposite to the arrow shown in FIG. 45), the longitudinal axis 273 is moved. Similarly, it rotates counterclockwise, and the pinion 271 similarly rotates counterclockwise.

  Thus, when the pinion 271 rotates counterclockwise, the rack 272 moves downward while meshing with the pinion 271 of the lower tooth portion 272a. At this time, the upper and lower guide pins 272f and 272g move downward along the long hole portions 261m and 261v of the pin support plates 261k and 261u of the holding frame 261, whereby the rack 272 moves downward.

  Further, when the rack 272 moves downward as described above, the pinion 281 rotates clockwise (opposite to the arrow direction in FIG. 48) contrary to the above, and the vertical axis 282b of the rack 282 is rotated. However, under the meshing of the tooth portion 282c with the pinion 281, the pinion 281 moves upward as the pinion 281 rotates clockwise. This means that the upper guide member RPb moves upward together with the upper left and right direction shaft 282a and the upper guide wall 290A. At this time, the left and right upper guide pins 282d and 282e move upward along the long hole portions 261p and 261r of the pin support plates 261o and 261q of the holding frame 261, so that the rack 282 moves upward.

  Further, when the rack 272 moves downward as described above, the lower guide member RPd moves together with the rack 272 because the lower guide member RPd is integrated with the rack 272. This means that the lower guide member RPd moves downward together with the lower left and right axis 272c and the lower guide wall 290B.

  As described above, when the upper guide member RPb moves upward and the lower guide member RPd moves downward, the upper guide member RPb and the lower guide member RPd move away from each other. In other words, when the upper guide wall 290A moves upward and the lower guide wall 290B moves downward, the upper guide wall 290A and the lower guide wall 290B move away from each other.

  Along with this, the upper guide wall 290A slides against the inclined surface 263h of the upper wall 263c of the holding frame 263 with the inclined surface 291 under the upward movement of the upper guide wall 290A, and moves the inclined surface 263h to the left and right upper side torsion springs. The lower guide wall 290B is slid to the inclined surface 63j of the lower wall 263d of the holding frame 263 by the inclined surface 292 under the downward movement of the lower guide wall 290B under the bias of 261g. The inclined surface 263j is moved rearward under the bias of the left and right torsion springs 261g while being in contact.

  Here, when the upper wall 263c and the lower wall 263d of the holding frame 263 move up and down as described above, the left and right upper guide pins 263g and the left and right lower guide pins 263g of the holding frame 263 are respectively left and right upper. Along the elongated hole portion 261e and the left and right lower elongated hole portion 261e, the respective urging forces of the left and right upper torsion springs 261g and the left and right lower torsion spring 261g are received along the corresponding elongated hole portions 261e from the front-rear intermediate portion. Move toward each rear end.

  As described above, the holding frame 263 is guided rearward by moving backward on the upper guide wall 290A and the lower guide wall 290B on the upper wall 263c and the lower wall 263d thereof. Move backwards. This means that the displacement plate member 262 is displaced from the advance position to the original position within the holding frame 261.

  Thus, when the displacement plate member 262 returns to the original position in this way, in the lock mechanism RP2, as shown in FIG. 45, the lock lever 274 returns to the original position, and the locking portion 41c of the locking member 41d. It is maintained in the state locked to. Therefore, after the turning operation of the shaft-shaped tool T is finished, 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 worker in the hall uses the key K to unlock the locking device 17 of the front door D, opens the front door D, and opens the security plate Sb. Is exposed to the front. Thereafter, the grip portion of the shaft-shaped tool T is gripped, and the shaft portion Ta is connected to the front-rear direction shaft 73.

  When the tool T is further rotated clockwise as shown in FIGS. 46 and 47, the front-rear shaft 273 is similarly rotated clockwise, and the pinion 271 is similarly rotated clockwise. At this time, the rack 272 of the vertical movement mechanism member RPb is further moved upward, and the upper guide member RPc and the lower guide member RPd are moved closer to each other.

  In addition, these movements reach the front end portion of each corresponding long hole portion 261e of each guide pin 263g, and reach the respective opposite end portions of each long hole portion 261m, 261v of each guide pin 272f, 272g. The guide pins 282e and 282d are stopped by reaching the respective lower end portions of the corresponding long hole portions 261r and 261p.

  Accordingly, as shown in FIG. 47, when the lock lever 274 is disengaged from the locking with the locking member 41c, the security plate Sb is released from the locked state with respect to the frame H. As a result, the security plate Sb can be released from the frame H.

  In such a state, after the operator opens the security plate Sb and completes the necessary processing, the operator closes the security plate Sb, grips the grip portion of the tool T, and moves the shaft portion Ta in the front-rear direction. Connected to the shaft 73. Then, by rotating the shaft tool T, the security plate Sb is locked to the frame body H when the lock lever 274 is locked to the locking portion 41c of the locking member 41d. Thereafter, the operator closes the front door D and locks the locking device 17 using the key K.

  In the fifth embodiment, the security plate Sb is configured to include the decorative members 260a as described above. The basis for such a configuration will be described.

  In pachinko gaming machines, in general, the production effect is enhanced by providing decorative parts such as electric parts on the front door. Here, in the pachinko gaming machine, although the game board is periodically replaced, the front door is usually 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 the fifth embodiment, each decorative component 260a protrudes from the security board Sb instead of the front door D. Therefore, if the security board Sb is exchanged together with the game board P, every time the exchange is performed, It is possible to newly enhance the effect of the decoration parts as a pachinko machine.

  As described above, in the fifth embodiment, the security plate Sb 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 Sb is closed, no gap is formed between the security board Sb and the gaming machine main body. Therefore, even if a piano wire or the like can be inserted from 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 Sb 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 Sb is locked to the frame body H by the lock mechanism RP2, the security plate Sb 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 262 is displaced forward using the shaft tool T while the security plate Sb is locked with the front door D closed. Thus, since the gap between the displacement plate member 262 and the game board P is increased, the above-mentioned ball biting can be eliminated without opening the front door D, which is convenient. At this time, since the security plate Sb remains locked as described above, the security of the pachinko gaming machine is improved in the same manner as before the ball bite is eliminated.

  In the fifth embodiment, as described above, each decorative component 260a is provided on the security board Sb. Therefore, in combination with the above-described operational effects, the effect produced by each decorative component 260a is changed to the game board. It can be increased each time P and security plate Sb are replaced.

  In addition, although the shape of security board Sb was made into the square shape in 5th Embodiment mentioned above, you may comprise by the shape (substantially circular shape) corresponding to the shape of the game area | region 32 in the board surface 31 of the game board P, The decorative component 260b may be disposed outside the security plate. In the fifth embodiment described above, the displacement plate member 262 of the security plate Sb is configured to be movable in the front-rear direction. However, the entire security plate bS may be configured to be movable in the front-rear direction.

(Sixth embodiment)
Next, a sixth embodiment of the pachinko gaming machine according to the present invention will be described. In the sixth embodiment, the ball fall prevention device BC described in the second embodiment is additionally employed in the game board P of the pachinko gaming machine described in the fifth embodiment. Similar to the second embodiment, the fall prevention device BC is assembled in the vicinity of the lower end portion of the inner rail 34 (the vicinity of the out port 36) of the game board P (see FIG. 13). Other configurations are the same as those of the fifth embodiment.

  In the sixth embodiment configured as described above, similarly to the fifth embodiment, when the glass plate 264 of the displacement plate 263 of the security Sb is in the original position in the closed state of the security plate Sb, the ball is prevented from falling. Similarly to the second embodiment, the ball receiving rail 100a of the device BC is urged forward by the coil spring 130 via the sliding body 111 of the upper sliding body 110 and comes into contact with the glass plate 264 in the original position. (See FIG. 14).

  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 security plate Sb comes into contact with the rising wall portion of the fixed frame 261 (corresponding to the rising wall portion 61g of the fixed frame 61) from the rear side thereof, and is separated rearward from the rear protruding wall 104 of the casing 100 by the flange portion 122b. positioned.

  In such a state, the upper slide body 110 is moved by the slide body main body 111 in accordance with the displacement of the displacement plate 263 to the forward movement position of the glass plate 264 accompanying the occurrence of the ball engagement as in the fifth 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 displaced forward while following the advance of the glass plate 264 (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.
