  In Patent Document 1, in a gaming machine provided with a winning device (50) that opens and closes a winning opening (51) where the gaming ball can win with the operation of the second special winning solenoid (52) by the opening and closing member (53). The device (50) is provided in the opening and closing member (53), between the closing position where the opening and closing member (53) closes the winning opening (51) and the opening position where the opening and closing member (53) opens the winning opening (51). The second special prize solenoid (52) is disposed on the connecting shaft (84) and the regulation part (85), which are integrally displaced with the opening / closing member (53), and the second special prize solenoid (52) is driven. Accordingly, it is configured to reciprocate in the vertical direction to the operating position corresponding to the lock position that restricts the opening of the opening / closing member (53) and the opening position of the opening / closing member (53). An actuating member (86).

  The actuating member (86) engageably engages with the connecting shaft (84), and the opening / closing member (53) is moved from the closed position to the open position as the actuating member (86) is displaced from the locked position to the actuated position. And the restricting portion (85) engageably and disengageably engage the restricting portion (85) to move the open / close member (53) from the closed position to the open position under engagement with the restricting portion (85). And a lock portion (86a) for restricting displacement. When the actuating member (86) is in the locked position, the engagement between the open / close actuating portion (89) and the connecting shaft (84) is released and the restricting portion (85) and the locking portion (86a) are engaged. Then, the displacement of the open / close member (53) from the closed position to the open position is restricted, and the lock portion (85) and the lock are locked at the lock release position in the process of moving the operating member (86) from the locked position to the operated position. As the engagement with the part (86a) is released and the open / close actuating part (89) and the connecting shaft part (84) engage, the actuating member (86) is displaced from the unlocked position to the actuating position, The opening and closing member (53) is displaced from the closed position to the open position.

  Thus, even if the opening / closing member (53) is directly opened, the winning opening can not be opened, and unauthorized opening of the opening / closing member (53) can be prevented. As the second special winning solenoid (52) is driven, the state is switched between locking and unlocking the opening / closing member (53), so that the entire winning device can be made compact.

  Furthermore, the mechanism accommodating portion (77) is formed in a frame shape that surrounds the rear and left and right sides of the actuating member (86), and a support piece (77a) is provided on the front surface. The support piece (77a) is adapted to be in contact with the actuating member (86) when the actuating member (86) moves to the locked position, and functions as a stopper for stopping and holding the actuating member (86) in the locked position. Do.

  However, according to the invention described in Patent Document 1, the engagement between the restricting portion (85) and the lock portion (86a), the opening / closing operation portion (89) and the connecting shaft portion (84) are engaged, and the stopper (77a) is used. The stop is described, and the winning device (50) is described in the lock position (FIG. 13), the unlock position (FIG. 15 (a)), and the operation position (FIG. 15 (b)). Although the opening and closing of 53) is restricted at the lock position, the opening / closing member (53), the linkage shaft (84), and the restricting portion (85) are displaced integrally, so structurally switching between the lock position and the lock release position In order to smooth the gap, a gap is required between the restricting protrusion (85) and the lock portion (86a) when the opening and closing member (53) is closed. If the gap between the restricting projection (85) and the lock part (86a) is too narrow at the time of closing, the rattle of the opening / closing member (53) will cause the actuating member (86) to fall down. There may be a problem. Further, when the opening and closing member (53) is closed, if the gap is increased, the opening angle at the time of improper blade opening by the external force is gradually increased, and foreign objects and the like are easily intruded. As a result, there is a structural problem that the opening and closing member (53) is rattling when the opening and closing member (53) is closed.

  Due to this play, the game ball swings little by little every time it collides with the opening / closing member (53), resulting in wear of the linkage shaft (84) and wear of the stopper (77a) for stopping the operation member (86). There is a problem that the amount of rattling gradually increases.

  Furthermore, when the opening and closing member (53) moves to the lock position, the actuating member (86) hits the stopper (77a), and the opening and closing member (53) bounces and moves with rattling.

In view of the above problems, the winning device of the gaming machine of the present invention can not enter the game ball from the winning opening when the opening and closing member is in the closing position, and when the opening and closing member is in the opening position In the winning device of the gaming machine, wherein the opening and closing member is configured to reciprocate between the closed position and the open position, the solenoid electromagnetically drives the plunger upward and the downward direction is by the plunger's own weight.

  Hereinafter, a winning apparatus 1 for a pachinko machine according to an embodiment of the present invention (hereinafter, simply referred to as a winning apparatus 1) will be described with reference to the drawings.

  The winning device 1 is provided with a plastic outer shell structure 1a (see FIGS. 8 and 9), a partition structure 1b for dividing the front side and the back side into vertical parts, and an opening / closing member 2. The opening / closing member 2 has a single-opening structure, and when the opening / closing member 2 is in the closed position, it becomes impossible to enter the game ball (not shown) from the winning opening (not shown), and when the opening / closing member 2 is in the open position A ball can be inserted, and the opening and closing member 2 is configured to reciprocate between the closed position and the open position.

  In the winning device 1, as shown in FIGS. 1 to 7, the solenoid 3a engages with the driving portion 3 for electromagnetically driving the plunger 3b in the vertical direction, and the plunger 3b to respond to the driving of the plunger 3b in the vertical direction. A second connecting member 4 that moves up and down, and a rotation shaft 5a that is a rotation center shaft, and the second opening and closing member 2 is rotated by rotating around the rotation shaft 5a A connecting member 5, a shaft member 6 connected to the second connecting member 5 for rotating the opening / closing member 2, and a spring 7 having one end 7a fixed and the other end 7b connected to the second connecting member 5; It is provided. The components will be described in detail below.

  The opening and closing member 2 is composed of a blade 2a and a fixed shaft 2b which is a rotation center of the blade 2a and is axially attached to the partition structure 1b.

  The drive unit 3 includes a holding member 3c that accommodates the solenoid 3a, and has an opening at the lower end of the holding member 3c for the plunger 3b to enter and exit. Here, the driving distance of the plunger 3b by the solenoid 3a is 5 to 6 mm in the vertical direction.

  The first connecting member 4 has an outer shell 4a for partitioning the outer surface, a linking member 4b which is an annular member having a through hole penetrating in the lateral direction, and a groove for inserting and locking the flange portion of the lower end of the plunger 3b And 4c.

  The second connecting member 5 has a crank shape, and the projecting arms 5b to 5d and the other end 7b of the spring 7 are formed at an angle in three directions with the rotation shaft 5a disposed substantially at the center thereof. An attachment portion 5e to be attached, a rib 5f protruding laterally from the vicinity of the rotation shaft 5a toward the first connection member 4, and a cooperation pin 5g loosely fitted with the cooperation member 4b and protruding in the axial direction are provided. As shown in FIG. 7, the rib 5f is opposed to the outer shell 4a on the side of the first connecting member 4 of the cooperation member 4b, and has an inclined surface such that the distance is separated as it goes upward with respect to the outer shell 4a.

  The shaft member 6 is rotatably supported by the outer shell structure 1a and the partition structure 1b (see FIG. 7) of the winning device 1 and a rotation shaft 6a to which the opening / closing member 2 is fixed, and fixed to the rotation shaft 6a At the same time, the link member 6 b is loosely fitted to the arm 5 b of the second connection member 5 and provided with a shaft 5 h protruding in the axial direction. By the link member 6b, regardless of the open / close position of the open / close member 2, the distance between the rotating shaft 6a and the shaft 5h is maintained to be constant.

  As shown in FIG. 7, in the closed position of the opening / closing member 2, a gap 9 is formed between the cooperation member 4b and the cooperation pin 5g, and when moving from the closed position to the open position, the outer shell 4a moves up and down. The member 4b and the cooperation pin 5g are joined.

  The spring 7 has a tensile coil spring structure, and the axial direction is arranged in the vertical direction, and one end 7a thereof is fixed to the outer shell structure 1a by a fastening member, and the other end 7b is attached to the mounting portion 5e of the second connection member 5. Be suspended. At this time, the spring 7 is installed by being pulled from the natural length, and always rotates the arm 5c of the second connecting member 5 clockwise in any of the open position, the closed position and the middle position. That is, an elastic force is applied to the arm 5c to move the opening / closing member 2 in the closing direction. As shown in FIG. 6, in the closed position, the opening and closing member 2 abuts against the stopper 10, and in the open position, the opening and closing member 2 abuts against the stopper 11 to restrict the rotational limit of the second connecting member 5 in the closing and opening directions. The elastic force by the spring 7 is a holding force for holding the position of the second connection member 5.

  It is preferable to make the electromagnetic force of the solenoid 3a a little stronger than usual and to make the elastic force of the spring 7 weaker than the electromagnetic force of the solenoid 3a. These adjustments can be made as appropriate according to the specifications of the winning device 1. Thus, in the closed position of the opening / closing member 2, the position of the second connecting member 5 is accurately held by the elastic force of the stopper 10 and the spring 7.

As shown in FIG. 7, the gap 8 is maintained between the rib 5 f of the second connection member 5 and the outer shell 4 a of the first connection member 4. The gap 8 is maintained at the minimum distance, for example, set at a narrow distance of 0.1 mm. The gap 8 can prevent an interference phenomenon such as collision or biting of the first connecting member 4 and the second connecting member 5, and the locking and unlocking can be stably performed without any problem.

  The operation of the winning device 1 of the present embodiment will be described with reference to the drawings.

  When the open / close member 2 is shifted from the open position of FIG. 3 to the closed position of FIG. 6, the solenoid 3a is switched from the excited state to the non-excited state, and the plunger 3b is lowered by its own weight as shown in FIG. Together with the downward movement, the lower side of the inside of the cooperation member 4b abuts on the cooperation pin 5g with the downward movement, and follows together with the lowering of the cooperation pin 5g. Thus, the second connecting member 5 rotates clockwise about the rotation shaft 5a. In addition to the fact that the first connecting member 1 is lowered by the own weight of the plunger 3b, an elastic force that causes the stretched spring 7 to return to its natural length acts, so that the spring 7 turns the second connecting member 5 clockwise. An elastic force to move is exerted, whereby the arm 5d is also rotated clockwise. Along with this, the shaft 5h rotates clockwise around the rotation shaft 5a, the link member 6b swings, and the rotation shaft 6a swings clockwise around the fixed shaft 2b. Along with this, the relationship of the gap 8 changes, and the rib 5 f and the shell 4 a move in the approaching direction.

  When the opening and closing member 2 abuts against the stopper 10, with the gap between the rib 5f of the second connecting member 5 and the outer shell 4a of the first connecting member 4 being held, the opening and closing member 2 is closed by the elastic force of the spring 7 and the stopper 10. Fix it. As a result, the positions of the open / close member 2, the second connection member 5, and the spring 7 are fixed, and the elastic force does not act on the first connection member 4. From there, by using the own weight of the plunger 3b and the first connecting member 4, a predetermined distance, for example, a section for the thickness of the rib 5f, the position of the plunger 3b and the first connecting member 4 is held With respect to the second connecting member 5 (cooperation pin 5g) being fixed, the locking is completed by reaching the lower limit position, which is a stable point, integrally with the second connecting member 5 (cooperation pin 5g). And the gap between the rib 5f and the shell 4a is about 0.1 mm (see FIG. 7).

  As described above, the elastic force that causes the spring 7 to rotate clockwise with respect to the arm 5c acts, and the rotation of the rib 5f to the right is prevented by the outer shell 4a. As a result, the gap 8 is enlarged. Since it is going to try, movement to the open position of opening and closing member 2 can be certainly barred.

  On the other hand, when the open / close member 2 is shifted from the closed position of FIG. 6 to the open position of FIG. 3, the solenoid 3a becomes non-excitation state to excitation state and the plunger 3b exerts an elastic force of its own weight and spring. Together with the movement of the first connecting member 4 upward, the thickness of the rib 5f, with the movement of the gap 9 between the cooperation pin 5g and the cooperation member 4b, the inside of the cooperation member 4b The lower side abuts on the cooperation pin 5g, and the rib 5f and the shell 4a are separated in the vertical direction, and the lock is released. Furthermore, along with the ascent of the cooperation pin 5g, the second connection member 5 rotates counterclockwise around the rotation shaft 5a, following the movement together. Since the arm 5c stretches the spring 7 with the counterclockwise rotation of the arm 5c of the second connecting member 5, a force acts to pull it back from the spring 7 to the arm 5c. Along with this, the shaft 5h rotates counterclockwise around the rotation shaft 5a, the link member 6b swings, and the rotation shaft 6a swings counterclockwise around the fixed shaft 2b. The gap 8 shown in FIG. 7 can act as a relief space, and the shape of the gap 8 can be changed, so that the rib 5f and the shell 4a can be moved in the separating direction. When the open position is reached, the opening / closing member 2 contacts the stopper 11 (see FIG. 6), and the position of the plunger 3b is fixed, whereby the positions of the first connecting member 4 and the second connecting member 5 are fixed. Therefore, the position of the opening and closing member 2 is regulated.

  According to the prize apparatus 1 of the present embodiment described above, the spring 7 is linked to the second connecting member 5 side, and the elastic force of the spring 7 always rotates the second connecting member 5 clockwise in the closing position of the opening / closing member 2 Since it is possible to prevent the back and forth of the opening and closing member 2 and eliminate small opening and closing operations due to the collision of the game ball with the opening and closing member 2, the opening time of the opening and closing member 2 can be accurately controlled. Further, the wear of the stoppers 10 and 11 for stopping the open / close member 2 by the open / close limit can be prevented, and the durability is also improved. Furthermore, since the gap 8 (the amount of play) between the first connection member 4 and the second connection member 5 can be minimized, the opening of the opening / closing member 2 due to the fraud can be minimized. The stoppers 10 and 11 are necessary for holding the open / close limit.

  According to the winning device 1 of the present embodiment, the opening and closing member 2, the first connecting member 4 and the second connecting member 5 are separately provided, and the solenoid 3a and the plunger 3b drive the first connecting member 4; By controlling the position of the second connection member 5 with the spring 7, it is possible to fix the open / close member 2 in a stable manner. Further, even if the opening and closing member 2 is to be opened from the outside, the position of the second connecting member 5 is held by the elastic force of the spring 7 so that the position of the second connecting member 5 is in the closing direction. For this reason, even if the player moves the opening / closing member 2 from the outside so as to open it, the second connecting member 5 can only be moved by a minute distance (about 0.1 mm), and its rib 5f is the first connecting Since it collides with the outer shell 4a of the member 4 and is locked and rotation of the opening / closing member 2 and the second connection member 5 is prohibited, it can contribute to fraud prevention. By moving the first connection member 4 with the solenoid 3a and the plunger 3b, the lock is smoothly released when the distance of the thickness of the rib 5f is exceeded, and the second connection member 5 is rotated by the cooperation of the cooperation member 4b.

  The opening and closing member 2, the first connecting member 4 and the second connecting member 5 are separated, the first connecting member 4 is driven by the solenoid 3a or its own weight, and the position of the second connecting member 5 is controlled by the spring 7 Since the elastic force is always applied so as to be in the closing direction, rattling and bouncing of the opening and closing member 2 or the game ball can eliminate small opening and closing operations due to a collision with the opening and closing member 2 and the opening time of the opening and closing member is accurate It can control. In addition, it is possible to prevent the wear of the stopper portion that stops the opening and closing member by the opening and closing limit, and the durability is also improved. Furthermore, since the gap 8 (the amount of play) between the first connection member 4 and the second connection member 5 can be minimized, the opening of the opening / closing member 2 due to the fraud can be minimized.
