Description

  The present invention relates to a pachinko gaming machine, and more particularly, to a pachinko gaming machine including a gaming machine main body having a gaming board and a front door supported by the gaming machine main body through the gaming board so as to be opened and closed.

  Conventionally, in this type of pachinko gaming machine, a pachinko gaming machine described in Patent Document 1 below has been proposed. On the surface of the game board of the pachinko gaming machine, there are provided various types of items related to the payout of game balls such as a start winning port device and a large winning port device.

  Here, the front door covers the game board when closed, and thus plays a role of protecting the above-mentioned various items.

JP 2009-291520 A

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

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

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

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

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

In solving the above-mentioned problems, the pachinko gaming machine according to the present invention, according to claim 1,
A gaming machine body (H, P) having a gaming board (P);
A front door (D) supported to be openable and closable by the gaming machine body,
In the pachinko gaming machine that opens the front door from the board surface (31) side and closes the front door to cover the game board from the board side,
It is equipped with a security board (S) provided between the gaming machine body and the front door,

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

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

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

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

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

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

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

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

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

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

  Further, as shown in any of FIGS. 19 to 24, the holding frame 63 has an upper protruding wall 63i and a lower protruding wall 63k, and the upper protruding wall 63i is an upper guide wall of the upper guide member RPc. It is integrally formed so as to protrude rearward from the rear end of the lower end of the upper wall 63c of the holding frame 63 so as to face 90A. Here, the upper protruding wall 63i is formed as an inclined surface 63h parallel to the inclined surface 91 of the upper guide wall 90A at the protruding end surface.

  As a result, the upper protruding wall 63i is pushed forward by the inclined surface 91 in accordance with the downward movement of the upper guide wall 90A under sliding contact with the inclined surface 91 of the upper guide wall 90A at the inclined surface 63h. Moved. Further, the upper protruding wall 63i is pulled by the left and right upper torsion springs 61g while sliding on the inclined surface 63h while sliding with the inclined surface 91 of the upper guide wall 90A while pushing the inclined surface 91 rearward. The upper guide wall 90A is moved upward.

  In addition, the lower protruding wall 63k is integrally formed to protrude rearward from the rear upper end of the lower wall 63d of the holding frame 63 so as to face the lower guide wall 90B of the lower guide member RPd. Here, the lower protruding wall 63k is formed as an inclined surface 63j parallel to the inclined surface 92 of the lower guide wall 90B at the protruding end surface. As a result, the lower protruding wall 63k is moved by the inclined surface 92 in accordance with the upward movement of the lower guide wall 90B under sliding contact with the inclined surface 92 of the lower guide wall 90B at the inclined surface 63j. It is pushed forward. Further, the lower projecting wall 63k is pulled by the left and right lower torsion springs 61g to push the inclined surface 92 rearward under sliding contact with the inclined surface 92 of the lower guide wall 90B at the inclined surface 63j. The lower guide wall 90B is moved downward while moving.

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

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

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

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

  In such a state, as shown in FIG. 19, the upper guide wall 90 </ b> A of the rack and pinion device RP is an inclined surface 63 h of the upper protruding wall 63 i of the holding frame 63 of the displacement plate member 62 below the inclined surface 91. As shown in FIGS. 8 and 9, the left and right upper guide pins 63g are respectively connected to the left and right straight elongated holes 61e of the upper wall 61a of the upper frame 61a by the respective spring forces of the left and right upper torsion springs 61g. It is pressed against the rear end.

  Further, as shown in FIG. 22, the lower guide wall 90B of the rack and pinion device RP is in contact with the inclined surface 63j of the lower protruding wall 63k of the holding frame 63 at the upper part of the inclined surface 92, so The side guide pins 63g are pressed against the rear end portions of the left and right linear elongated holes 61e of the upper wall 61d of the holding frame 61 by the spring force of the left and right lower torsion springs 61g.

  According to the above, the displacement plate member 62 is held in its original position as shown in FIGS. 4, 8 and 9. At this time, as shown in FIG. 16, the pinion 81 meshes with the upper portion of the upper tooth portion 72 h of the rack 72 and the lower portion of the tooth portion 82 c of the rack 82.

  Further, as shown in FIG. 13, the lock mechanism RP2 is locked to the locking portion 41c of the locking member 41d by the lock lever 74 to lock the security plate S to the frame H of the gaming machine main body. Yes.

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

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

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

  In such a state, in the game process by the pachinko gaming machine, the game ball is sandwiched between the displacement plate member 62 and the board surface 31 of the game board P, so that the so-called ball biting is performed on the board surface of the game board P. When it occurs between 31 and the displacement plate member 62, the security plate S remains closed in the locked state by the lock mechanism RP2 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, 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 direction shaft 73.

  When the shaft-shaped tool T is rotated clockwise as shown by an arc-shaped arrow in FIG. 13 against the urging force of each torsion spring 61g, the front-rear shaft 73 is moved to the shaft-shaped tool in the drive mechanism member RPa. The pinion 71 rotates in the same direction as the front-rear direction shaft 73.

  When the pinion 71 rotates in this way, the rack 72 moves upward as shown in FIG. 14 while meshing with the pinion 71 of the lower tooth portion 72a. At this time, the upper and lower guide pins 72f and 72g move upward along the long hole portions 61m and 61v of the pin support plates 61k and 61u of the holding frame 61, so that the rack 72 moves upward.

  Further, when the rack 72 moves upward as described above, the pinion 81 rotates counterclockwise (arrow direction shown in the drawing) as shown in FIG. 16, and the vertical axis 82b of the rack 82 is moved to FIG. As shown, when the pinion 81 is engaged with the pinion 81, the pinion 81 moves downward as the pinion 81 rotates counterclockwise. This means that the upper guide member RPb moves downward together with the upper left / right direction shaft 82a and the upper guide wall 90A. At this time, the left and right upper guide pins 82d and 82e move downward along the long hole portions 61p and 61r of the pin support plates 61o and 61q of the holding frame 61, whereby the rack 82 moves downward.

  Further, when the rack 72 moves upward as described above, the lower guide member RPd moves together with the rack 72 because the lower guide member RPd is integrated with the rack 72. This means that the lower guide member RPd moves upward together with the lower left / right direction shaft 72c and the lower guide wall 90B.

  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 90A moves downward and the lower guide wall 90B moves upward, the upper guide wall 90A and the lower guide wall 90B move in directions toward each other.

  Accordingly, the upper guide wall 90A pushes the inclined surface 63h forward while sliding in contact with the inclined surface 63h of the upper wall 63c of the holding frame 63 on the inclined surface 91 while moving downward. At the same time, the lower guide wall 90B pushes the inclined surface 63j forward while sliding on the inclined surface 63j of the lower wall 63d of the holding frame 63 on the inclined surface 92 under the upward movement. To do.

  Here, when the upper wall 63c and the lower wall 63d of the holding frame 63 are moved downward and upward as described above, the left and right upper guide pins 63g and the left and right lower guide pins 63g of the holding frame 63 are respectively left and right upper. The long holes 61e and the left and right lower long holes 61e are arranged along the corresponding long holes 61e against the biasing forces of the left and right upper torsion springs 61g and the left and right lower torsion springs 61g. Move toward the middle part in the front-rear direction.

  As described above, the holding frame 63 is pushed forward by the upper guide wall 90A and the lower guide wall 90B at the upper wall 63c and the lower wall 63d, and thus is guided forward, as shown in FIGS. As shown at 23, it moves forward. This is because the displacement plate member 62 is displaced from the original position to the advance position in the holding frame 61, and the distance between the glass plate 64 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 rotation operation of the shaft tool T as described above is performed and the displacement plate member 62 is displaced to the advance position, the lock lever 74 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.

  Therefore, in a state where the ball biting has been eliminated, the security plate S is locked by the lock mechanism RP2 while being closed. At this time, in the security plate S, even if the distance between the displacement plate member 62 and the board surface 31 of the game board P is increased as described above, the relationship between the displacement plate member 62 and the holding frame 61 is Since this is the same as when the displacement plate member 62 is in the original position, 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 (opposite to the arrow shown in FIG. 13), the front / rear direction shaft 73 is moved. Similarly, it rotates counterclockwise, and the pinion 71 similarly rotates counterclockwise.

  Thus, when the pinion 71 rotates counterclockwise, the rack 72 moves downward under meshing with the pinion 71 of the lower tooth portion 72a. At this time, the upper and lower guide pins 72f and 72g move downward along the long hole portions 61m and 61v of the pin support plates 61k and 61u of the holding frame 61, so that the rack 72 moves downward.

  Further, when the rack 72 moves downward as described above, the pinion 81 rotates clockwise (opposite to the arrow direction in FIG. 16) contrary to the above, and the vertical axis 82b of the rack 82 is rotated. However, when the pinion 81 is rotated clockwise, the tooth portion 82c meshes with the pinion 81 and moves upward. This means that the upper guide member RPb moves upward together with the upper left / right direction shaft 82a and the upper guide wall 90A. At this time, the left and right upper guide pins 82d and 82e move upward along the long hole portions 61p and 61r of both the pin support plates 61o and 61q of the holding frame 61, whereby the rack 82 moves upward.

  Further, when the rack 72 moves downward as described above, the lower guide member RPd moves together with the rack 72 because the lower guide member RPd is integrated with the rack 72. This means that the lower guide member RPd moves downward together with the lower left / right direction shaft 72c and the lower guide wall 90B.

  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 90A moves upward and the lower guide wall 90B moves downward, the upper guide wall 90A and the lower guide wall 90B move in directions away from each other.

  Along with this, the upper guide wall 90A slides against the inclined surface 63h of the upper wall 63c of the holding frame 63 on the inclined surface 91 under the upward movement of the upper guide wall 90A. The lower guide wall 90B is slid onto the inclined surface 63j of the lower wall 63d of the holding frame 63 by the inclined surface 92 under the downward movement of the lower guide wall 90B. The inclined surface 63j is moved rearward under the bias of the left and right torsion springs 61g while in contact.

  Here, as described above, when the upper wall 63c and the lower wall 63d of the holding frame 63 move up and down, respectively, the left and right upper guide pins 63g and the left and right lower guide pins 63g of the holding frame 63 respectively Along the elongated hole portion 61e and the left and right lower elongated hole portion 61e, and receiving the respective urging forces of the left and right upper torsion springs 61g and the left and right lower torsion springs 61g, along the corresponding elongated hole portions 61e, Move toward each rear end.

  As described above, the holding frame 63 is guided rearward by moving backward on the upper guide wall 90A and the lower guide wall 90B on the upper wall 63c and the lower wall 63d. Move backwards. This means that the displacement plate member 62 is displaced from the advance position to the original position in the holding frame 61.

  Thus, when the displacement plate member 62 returns to the original position in this way, in the lock mechanism RP2, as shown in FIG. 13, the lock lever 74 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 hall operator unlocks the locking device 17 of the front door D using the key K and opens the front door D. Is exposed to the front. Thereafter, the grip portion of the 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 in the clockwise direction as shown in FIGS. 14 and 15, the front-rear shaft 73 is similarly rotated in the clockwise direction, and the pinion 71 is similarly rotated in the clockwise direction. At this time, the rack 72 of the vertical movement mechanism member RPb further moves upward, and the upper guide member RPc and the lower guide member RPd move closer to each other.

  In addition, these movements reach the front end portions of the corresponding long hole portions 61e of the respective guide pins 63g, and reach the respective opposite end portions of the corresponding long hole portions 61m and 61v of the respective guide pins 72f and 72g. In addition, the guide pins 82e and 82d are stopped when they reach the corresponding lower end portions of the corresponding long hole portions 61r and 61p.

  Accordingly, as shown in FIG. 15, when the lock lever 74 is disengaged from the locking with the locking member 41 c, the security plate S is released from the locked state with respect to the frame body H. As a result, the security plate S can be opened from the frame H.

  In such a state, after the operator opens the security plate S and completes the necessary processing, the operator closes the security plate S, grips the grip portion of the tool T, and moves the shaft portion Ta in the front-rear direction. Connected to the shaft 73. When the lock lever 74 is locked to the locking portion 41c of the locking member 41d by rotating the shaft tool T, the security plate S is locked to the frame H. Thereafter, the operator closes the front door D and locks the locking device 17 using the key K.

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

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

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

  Further, as described above, since the security plate S is locked to the frame H by the lock mechanism RP2, the security plate S cannot be freely opened. For this reason, the security in the pachinko gaming machine is improved.

  Further, when the ball bite occurs, as described above, the displacement plate member 62 is displaced forward using the axial tool T while the security plate S is locked with the front door D closed. Thus, since the distance between the displacement plate member 62 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 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.

  The security plate S has a quadrangular shape in the above-described embodiment. However, the security plate S may be formed in 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 62 of the security plate S is configured to be movable in the front-rear direction. However, the entire security plate S may be configured to be movable in the front-rear direction.
