1. Technical Field
The present invention relates to an entertainment button device and a game machine, and more specifically to an entertainment button device having a button-up-and-down mechanism to move an entertainment button up and down, and a game machine including the entertainment button.
2. Related Art
Conventionally, a pachinko game machine includes a frame body in which a game board is set, and an opening and closing body. The opening and closing body is supported to be able to open and close by the frame body and includes a transparent plate that covers the board surface of the game board in the closed position. A tray unit having an accumulating tray to accumulate playing balls is provided below the opening and closing body (below the transparent plate). In recent years, mainstream pachinko game machines include an entertainment button device. This entertainment button device has an entertainment button that the player can push, and is set in a tray unit, as disclosed in, for example, Japanese Patent No. 3989287, and Japanese Patent Application Laid-Open No. 2009-56085. The entertainment button device has a spring that biases the entertainment button to the moving-up direction, and is generally configured to push the entertainment button from the upper side of the tray unit.
This entertainment button device has a configuration where the entertainment button is fitted into a bottom hole formed in the upper end of the tray unit to be able to move up and down. In the normal operation position, the entertainment button is held to protrude upward from the tray unit. When the entertainment button is pushed from the normal operation position to the pushed position, and then is released from being pushed, it returns to the normal operation position and held in this position. When the button is pushed during a period of time in which the button can be operated, the push operation is detected, and therefore a specific entertainment in the game is performed. This enhances the player's sense of participation and improves the effect of the entertainment in the game.
By the way, in the entertainment button device disclosed in 3989287, the entertainment button moves between the normal operation position and the pushed position. The position in which the entertainment button is held is alternately switched between the normal operation position and the pushed position. The entertainment button is set in a button case to be able to move up and down, and a spring that biases the entertainment button to the direction in which the entertainment button moves up is also set in the button case. A solenoid actuator (hereinafter referred to as “solenoid”) moves the button case between a position in which the entertainment button is held in the normal operation position and a position in which the entertainment button is held in the pushed position.
Meanwhile, in the entertainment button device disclosed in 2009-56085, the entertainment button moves over the normal operation position, the pushed position and a protruding position in which the entertainment button protrudes much further than in the normal operation position. The position of the entertainment button is alternately switched between the normal operation position and the protruding position. A stopper plate is formed integrally with the entertainment button via a shaft, and a locking member is provided to be able to engage with the stopper plate. The locking member is engaged with the stopper plate by the solenoid to move between a position in which the entertainment button is held in the normal operation position and a position in which the entertainment button is held in the protruding position.
With the entertainment button device disclosed in 3989287, the button case is moved by the solenoid to allow the entertainment button to move between the normal operation position and the pushed position. Meanwhile, with the entertainment button disclosed in 2009-56085, the locking member is moved by the solenoid to allow the entertainment button to move between the normal operation position and the protruding position.
However, with the above-described related art, it is difficult to desirably move up and down the entertainment button, for example, the entertainment button is stopped temporarily at a predetermined position or moves up and down repeatedly, because the entertainment button is controlled through the solenoid to only move up and down between the two positions (between the normal operation position and the pushed position in 3989287; between the normal operation position and the protruding position in 2009-56085), which are the upper and lower limit positions to which the solenoid moves up and down. That is, there is a limitation in improving the effect of the entertainment of a game by moving the entertainment button up and down.
Here, with a general entertainment button device, the entertainment button is small and has a short stroke of up-and-down movement. Therefore, even if the entertainment button moves up and down, the movement is less represented, and consequently is not much help to the improvement of the effect of the entertainment in a game. To solve this drawback, an approach is proposed to increase the size of the entertainment button to lengthen the stroke of up-and-down movement. However, a large solenoid is required to lengthen the stroke of the up-and-down movement. With such a large solenoid, the entertainment button is not likely to smoothly move between the above-described two positions. Moreover, there is another problem of the arrangement and the installation of the solenoid. The above-described problem in the control of the entertainment button to move up and down by the solenoid still remains.
It is therefore, an object of the present invention to provide an entertainment button device and a game machine. The entertainment button device has a button-up-and-down mechanism to move an entertainment button up and down. This mechanism allows the entertainment button to smoothly and desirably move up and down.
According to a first aspect of the present invention, an entertainment button device includes: an entertainment button that a player can push; and a button-up-and-down mechanism configured to move the entertainment button up and down from a predetermined normal operation position to a protruding position in which the entertainment button protrudes upward from the normal operation position. The button-up-and-down mechanism includes: a shaft member extending in a moving direction of the entertainment button; a rotating mechanism configured to rotate the shaft member; an engagement part configured to move up and down together with the entertainment button; a convex portion having an inverted trapezoid shape and a concave portion having a traperized shape that are formed on an outer periphery of the shaft member; a spiral guide part formed in a spiral manner on one end of the convex portion in a circumferential direction, wherein the engagement part engages with the spiral guide part; and a straight part formed on the other end of the convex portion in the circumferential direction, wherein the straight part extends in parallel with a direction of a central axis of the shaft member, wherein: when the rotating mechanism rotates the shaft member in a specific direction, the engagement part moves to an upper end of the shaft member, engaging with the spiral guide part, so that the entertainment button moves to the protruding position; and when the entertainment button is pushed in a position between the normal operation position and the protruding position, the concave portion prevents the engagement part from contacting the spiral guide part and allows the engagement part to move to a lower end of the shaft member, so that the entertainment button moves to the normal operation position.
According to a second aspect of the present invention, the shaft member is provided inside the entertainment button; an annular member is provided in the entertainment button and located outside the outer periphery of the shaft member; and the engagement part is provided on an inner periphery of the annular member to protrude to the shaft member, wherein the engagement part can engage with the spiral guide part.
According to a third aspect of the present invention, the entertainment button device further includes a smoothing guide part continuing to a base end of the spiral guide part and extending in parallel with a plane orthogonal to a central axis of the shaft member. The engagement part engages with the smoothing guide part to hold the entertainment button in the normal operation position.
According to a fourth aspect of the present invention, a game machine having the entertainment button device is provided.
With the entertainment button device and the game machine according to the present invention, it is possible to smoothly move the entertainment button up and down by means of the button-up-and-down mechanism, and therefore improve the effect of the entertainment in a game.

The equipment makes entertainment along the progression of a game using playing balls.
Next, the tray unit 7, and the entertainment button device 9 and the discharge device 10 set in the tray unit 7, will be described in detail.
First, the tray unit 7 will be described. As shown in
The length of the upper tray 8a in the longitudinal direction is reduced from a position near the center of the upper tray 8a such that the front wall of the upper tray 8a in the right side is placed in the back rather than in the left side. The main bottom part of the upper tray 8a gently tilts down to the right, and therefore playing balls are introduced from the right end part of the upper tray 8a into the ball feeding device. The front wall of the lower tray 8b bulges forward in the right side rather than in the left side, and the bottom part of the lower tray 8b gently tilts forward and to the right. Playing balls are introduced from the front right part of the lower tray 8b into the discharge device 10, drop down to the bottom part of the discharge device 10 and are discharged to the outside of the game machine 1. A ball accommodating case (not shown), so-called “gold mine” is placed below the discharge device 10. The playing balls discharged from the discharge device 10 are received by and accommodated in the ball accommodating case.
The playing balls accumulated in the lower tray 8b may not be discharged from the discharge device 10 to the outside but supplied to the upper tray 8a. In this case, the playing balls accumulated in the lower tray 8b are taken out with the left hand while the player grips the launching handle 11 with the right hand. At this time, the playing balls are likely to run over from the upper right of the lower tray 8b due to the shape of the front wall of the lower tray 8b, the manner of taking out the playing balls by the player and so forth. Therefore, in order to prevent this, a transparent plate 8c (see
This transparent plate 8c bends to protrude forward a little, and also the upper edge of the transparent plate 8c curves such that the slope angle of the upper edge increases to the right to increase the height of the transparent plate 8c to the right. The bottom edge of the transparent plate 8c is fixed to the front wall of the lower tray 8b. The right edge of the transparent plate 8c is fixed to the part of the unit main body 7a, which is the right wall of the space above the lower tray 8b. The player can see and check the playing balls located behind the transparent plate 8c, and the transparent plate 8c has the upper edge with the shape which does not interfere with the left hand taking out the playing balls. Thus, the transparent plate 8c allows the player to reliably take out playing balls from the lower tray 8b without dropping playing balls.
The entertainment button device 9 and the discharge device are set in the central part of the tray unit 7. The entertainment button device 9 is arranged such that the entertainment button 40 can be pushed from the upper side of the tray unit 7. The discharge device 10 is arranged in the lower end of the tray unit 7 to be located on the right side of the lower tray 8b and below the entertainment button device 9. The discharge device 10 is fixed to a device mounting frame part 7b (see

As shown in
Here, another configuration is possible where a plurality of reinforcing metal plates are provided instead of the reinforcing metal plate 39, and the discharge device 10 is fixed to the device mounting frame part 7b of the unit main body 7a via the plurality of reinforcing metal plates. In this case, at least one of the plurality of reinforcing metal plates (for example, a pair of reinforcing plates corresponding to a left plate piece 39a and a right plate piece 39b) may be placed on and attached to the plate support portions (for example, the pair of plate support portions 7b1 and 7b2) formed in the device mounting frame part 7b, contacting face-to-face.
Next, the entertainment button device 9 will be explained. The entertainment button device 9 is configured to be able to move the entertainment button 40 over a predetermined normal operation position shown in
A large-sized entertainment button device 9 is provoded, where the entertainment button 40 is several times as large as a general entertainment button and moves up and down in a stroke several times as long as a general entertainment button.
Here, the direction in which the entertainment button 40 moves over the normal operation position, the pushed position and the protruding position, is defined as the direction in which the entertainment button 40 moves up and down. One end to which the entertainment button 40 moves up is referred to as “front end” meanwhile the other end to which the entertainment button 40 moves down is referred to as “base end.” Hereinafter, the direction in which the entertainment button 40 moves up and down is simply referred to as “moving direction.” In addition, the direction in which the entertainment button 40 moves up is simply referred to as “moving-up direction”, the direction in which the entertainment button 40 moves down is simply referred to as “moving-down direction”, and the center of the axis of the entertainment button 40 (and a button case 50 and a shaft member 68 described later) is simply referred to as “central axis.”

As shown in
The upper base 58 is fixed to the lower base 59 while the horizontal lower surface 58c1 and the inclined lower surface 58c2 of the upper base 58 are placed on the horizontal upper surface 59a1 and the inclined upper surface 59a2 of the lower base 59 through rubber cushion sheets 58d1 and 58d2, respectively. The peripheral wall 58a of the upper base 58 leans forward a little from the upright state. The main parts of the button-up-and-down mechanism 60 are mounted on the upper base 58.
As shown in
An outer flange part 42c formed on the lower end of the peripheral wall 42b of the button cover 42 is placed on an outer flange part 41c formed on the lower end of the peripheral wall 41b of the button body 41. In this state, the upper wall 41a of the button body 41 contacts (abuts on) the upper wall 42a of the button cover 42. The button cover 42 is supported by the button body 41 and moves up and down with the button body 41.
As shown in
The movable annular member 43b is biased in the moving-down direction in which the movable annular member 43b is placed apart from the fixed annular member 43a by a pair of left and right spring members 43c with a stronger biasing force than of the pair of biasing members 55. When the entertainment button 40 is in a position other than the pushed position, the movable annular member 43b is placed apart from the fixed annular member 43a in the moving-down direction.
As shown in
The entertainment button 40 moves up and down in the direction in which the peripheral wall 50a of the button case 50 inclines, that is, the entertainment button 40 moves up and down while leaning forward in the moving-up direction from the upright state. The inner peripheral wall 7c2 of the buttonhole 7c formed in the unit main body 7a is fitted into the upper end of the peripheral wall 50a of the button case 50 from below, so that the entertainment button 40 protruding from the button case 50 moves into and out of the button hole 7c. An inner flange part 50c formed in the upper end of the peripheral wall 50a of the button case 50 is placed on the outer flange part 42c of the button cover 42 to prevent the button cover 42 from falling out in the moving-up direction.
The button case 50 has a plurality of (three) outlets 51 to 53 (openings 51 to 53) to discharge foreign matters such as liquid between the outer periphery (the peripheral wall 42b of the button cover 42) of the entertainment button 40 and the peripheral wall 50a of the button case 50, to the outside of the button case 50.
The plurality of outlets 51 to 53 are formed in the lower edge of the peripheral wall 50a of the button case 50 such that the outlets 51 to 53 are placed apart from each other in the circumference direction. The outlet 51 lying between the outlets 52 and 53 is formed in the lower edge of the front part of the peripheral wall 50a of the button case 50. This outlet 51 serves as a main opening to discharge foreign matters to the outside. Each of the outlets 51 to 53 has a rectangular shape. The lower edge of each outlet is formed by the outer periphery the bottom wall 50b of the button case 50.
For example, if the player spills beverage on the entertainment button 40 or over the vicinity of the entertainment button 40, the liquid as a foreign matter entering and flowing between the peripheral wall 42b of the button cover 42 and the peripheral wall 50a of the button case 50 is surely discharged directly from any of the plurality of outlets 51 to 53, or, after reaching the bottom wall 50b of the button case 50 once.
In addition, the outlets 51 to 53 also serve as a plurality of air inlets 51 to 53 for a sealed space which is enclosed by the entertainment button 40 and the button case 50 when the entertainment button 40 moves up and down. That is, when the entertainment button 40 moves up, the sealed space increases in volume, and therefore the plurality of air inlets 51 to 53 suck in the air from the outside. Meanwhile, when the entertainment button 40 moves down, the sealed space reduces in volume, and therefore the plurality of air inlets 51 to 53 discharge the air in the sealed space to the outside.
As shown in
The button guide mechanism 61 includes: a pair of front and back metal guide rods 62 extending in the moving direction; and a pair of front and back cylindrical parts into which the pair of guide rods 62 are fitted, respectively (not shown). The pair of cylindrical parts is formed integrally with the fixed annular part 43a of the entertainment button 40. The button guide mechanism 61 retains the posture of the entertainment button 40 and guides the entertainment button 40 to be able to move up and down but not to be able to rotate around the central axis.
While its base ends are fixed to the upper base 58, the pair of guide rods 62 extends from the upper base 58 in the moving-up direction, penetrates the bottom wall 50b of the button case 50, penetrates the movable annular member 43b and the fixed annular member 43a of the entertainment button 40 in the button case 50. Then, the pair of guide rods 62 is inserted into the entertainment button 40 from the base end side. A discoid stopper plate 63 made of synthetic resin is fixed to the upper ends of the pair of guide rods 62 in the entertainment button 40.
The entertainment button 40 is in the pushed position while the fixed annular member 43a contacts the movable annular member 43b and also the movable annular member 43b contacts the bottom wall 50b of the button case 50. On the other hand, the entertainment button 40 is in the protruding position while the fixed annular member 43a contacts the lower surface of the stopper plate 63, and therefore is stopped by the stopper plate 63. An LED board 64 is mounted on the upper surface of the stopper plate 63. A plurality of LEDs 65 are packaged on the upper surface of the LED board 64. Moreover, a first concave optical detecting part 67 such as a photosensor is attached to the lower surface of stopper plate 63.
Meanwhile, a second convex detecting part 43d is attached to the fixed annular member 43a. Detection of the entertainment button 40 being held in the protruding position is based on the fact that the convex second detecting part 43d is inserted into or approaches the first concave detecting part 67.
The button body 41 including the upper wall 41a and the peripheral wall 41b is formed as a light-transmissive lens part. When the LEDs 65 emit light, the light transmits through the button body 41 (lens part) to illuminate the button body 41. Here, a plurality of conducting wires that allow the plurality of LEDs 65 to emit light extend upward from the upper base 58 side and are connected to the LED board 64. A rectangular cylindrical wiring accommodating member 66 that accommodates and guides these conducting wires extend in the moving direction to connect between the upper base 58 and the stopper plate 63 while penetrating the fixed annular member 43a and the movable annular member 43b of the entertainment button 40.
Here, the button cover 42 is provided to be able to rotate relative to the button body 41. Therefore, even if the player rotates the button cover 42, only the button cover 42 runs idle but any external load is not applied to rotate the button body 41, so that it is possible to reliably prevent the button body 41 and the button guide mechanism 61 from being damaged due to an external load.
In addition, a rounded portion 42d having an arc cross-section is formed at the boundary between the upper wall 42a and the peripheral wall 42b of the button cover 42. As shown in
The pair of biasing members 55 is formed by a pair of coil springs. The pair of coil springs is put around the pair of guide rods 62 respectively in the button case 50. Here, the pair of coil springs 55 is compressed and set between the movable annular member 43b of the entertainment button 40 and the upper wall 58b of the upper base 58 (or the bottom wall 50b of the button case 50).
The shaft member 68 is provided to align its central axis with the central axis of the entertainment button 40. While its base end is supported by the upper base 58 to be able to rotate, the shaft member 68 extends from the upper base 58 in the moving-up direction and penetrates the bottom wall 50b of the button case 50. Then, the shaft member 68 penetrates the movable annular member 43b and the fixed annular member 43a of the entertainment button 40 and is inserted into the entertainment button 40 from the base end side of the entertainment button 40 in the button case 50. That is, the entertainment button 40 is provided with the annular member 43 which is arranged outside of the outer periphery of the shaft member 68.
The rotating mechanism 70 includes an electric motor 71, a driving gear 72, an intermediate two-stage gear 73 and a driven gear 74. The electric motor 71 is attached to the upper base 58 to face the moving-up direction. The driving gear 72 is mounted on an output shaft 71a of the electric motor 71.

The intermediate two-stage gear 73 is rotatably supported by the upper base 58 while the driven gear 74 is fixed to the base end of the shaft member 68.
The up-and-down operation mechanism 75 includes a pair of left and right engagement parts 76 that moves with the entertainment button 40 and a pair of spiral guide parts 77 provided on the outer periphery of the shaft member 68. The pair of engagement parts 76 engages with the pair of spiral guide parts 77, respectively, while the entertainment button 40 is biased by the biasing members 55 to the moving-up direction. Then, the rotating member 70 rotates the shaft member 68, so that the pair of spiral guide parts 77 can move the pair of engagement parts 76 in the moving direction. The pair of engagement parts 76 and the pair of spiral guide parts are symmetric with respect to the central axis.
Each of the engagement parts 76 is formed by a pin member. The pin members are mounted to the movable annular member 43b and protrude from the inner periphery of the movable annular member 43b to the shaft member 68 (to the central axis) in the direction orthogonal to the central axis. By this means, the engagement parts 76 can engage with the spiral guide parts 77 (see
As shown in
A pair of smoothing guide parts 78 are formed on the outer periphery of the shaft member 68, which continues to the base ends of the pair of spiral guide parts 77 (the first spiral guide portion 77a) and extends in parallel with the plane orthogonal to the central axis of the shaft member 68. The pair of the engagement parts 76 engages with the pair of the smoothing guide parts 78, respectively, to hold the entertainment button 40 in the normal operation position. The pair of smoothing guide parts 78 is also symmetric with respect to the central axis.
Here, a pair of convex portions 68a is formed symmetrically with respect to the central axis on the outer periphery of the shaft member 68. Meanwhile, a pair of concave portions 68b is formed between the pair of convex portions 68a, symmetrically with respect to the central axis. The surface of the pair of convex portions 68a forms part of a cylindrical surface around the central axis while the surface of the pair of convex portions 68b forms part of a cylindrical surface with a smaller diameter than of the surface of the convex portions 68a.
Each of the convex portions 68a has an inverted trapezoid shape. A spiral guide part 77 (including the first spiral guide portion 77a and the second spiral guide portion 77b) is formed in a step-like manner on one edge of the convex portion 68a in the circumference direction (the boundary with the concave portion 68b). Meanwhile a smoothing guide part 78 is formed on the base end of each convex portion 68a in a step-like manner. In addition, a straight part 68c extending in parallel with the direction of the central axis of the shaft member 68 is formed on the other edge of each convex portion 68a in the circumference direction (the boundary with the concave portion 68b).
When the entertainment button 40 is located between the normal operation position and the protruding position, and when the entertainment button 40 is located in the protruding position, each engagement part 76 provided in the entertainment button 40 is placed in the concave portion 68b. That is, each engagement part 76 is placed between the spiral guide part 77 of one convex portion 68a and the straight part 68c of the other convex portion 68a, and therefore can engage with the spiral guide part 77.
As shown in
In addition, as shown in
As shown in
Here, when the rotating speed of the shaft member 68 is fixed, the moving speed of the entertainment button 40 is slower in a first case in which the engagement part 76 engages with the first spiral guide portion 77a than in a second case in which the engagement part 76 engages with the second spiral guide portion 77b. That is, the load on the shaft member 68 to move the entertainment button 40 up and down is smaller in the first case than in the second case.
As shown in
After that, when the entertainment button 40 is released from being pushed, it returns to the position at which the push operation was started. To be more specific, when the entertainment button 40 moves up or down (the shaft member 68 rotates), the entertainment button 40 returns to a position near the position at which the push operation was started. Here, when the entertainment button 40 is pushed to the pushed position, the shaft member 68 is rotated to place the pair of smoothing guide parts 78 in the direction in which the pair of engagement parts 76 moves up. To be more specific, when the entertainment button 40 is pushed from the protruding position to the pushed position, the shaft member 68 is rotated a little in the direction of arrow I. As a result, when the entertainment button 40 is released from being pushed, the pair of engagement parts 76 engages with the pair of smoothing guide parts 78. Consequently, the entertainment button 40 returns to the normal operation position.
On the other hand, as shown in
As described above, the shaft member 68 is rotated in the direction of arrow I shown in
Next, the discharge device 10 will be explained. As shown in
The case member 80 has a rectangular shape in a plan view and has a predetermined thickness in the vertical direction. The opening and closing mechanism 83 is accommodated and mounted in the case member 80. This case member 80 is set from below in the lower end part of the device accommodating hole 7d formed in the unit main body 7a of the tray unit 7a. The outer peripheral part of the case member 80 is mounted to the reinforcing metal plate 39 attached to the unit main body 7a, with a plurality of bolts (not shown). A pedestal 80a is formed on the upper surface of the case member 80. The support leg 59b of the lower base 59 is fixedly placed on the pedestal 80a.
The discharge passage 81 is formed in the front part of the case member 80 in the left side. A ball introducing inlet 81a that opens into the left side to face the inside of the lower tray 8b is formed in the upstream of the discharge passage 81. A ball outlet 81b is formed in the downstream of the discharge passage 81b. This ball outlet 81b opens downward to face the outside and is formed on the right side of the ball introducing inlet 81a. The opening and closing plate 82 is supported to be able to slide right and left in the case member 80, and therefore can open and close the ball outlet 81b.
The opening and closing mechanism 83 includes: an operating member 90 supported in the case member 80 to be able to move forward and backward and also to be able to be locked in the forward movement retention position shown in
The operating member 90 is placed above the arm member 91 and the operated member 92 (the opening and closing plate 82). An operating portion 90a is provided in the front end of the operating part 90 to protrude forward from the case member 80 so that the player can operate the operating portion 90a. The arm member 91 is formed in a wedge shape in a plan view. The rear end part of the arm member 91 is rotatably supported in the case member 80.
A first engagement pin 90b provided at the rear end of the operating member 90 to protrude downward is movably fitted into a first elongate hole 91a formed in the length direction of the back part of the arm member 91. A second engagement pin 91b provided at the front end of the arm member 91 to protrude downward is movably fitted into a second elongate hole 92a formed in the operated member 92 in the longitudinal direction. In this way, the operating member 90, the arm member 91 and the operated member 92 are coupled to each other to operate together.
When the operating member 90 is pushed backward from the forward movement retention position, the pushing force allows the arm member 91 to rotate counterclockwise in a plan view, so that the opening and closing plate 82 is slid to the right hand (open position) with the operated member 92. After that, when released from being pushed, the operating member 90 returns to the forward movement retention position while the open retention mechanism 84 does not hold the opening and closing plate 82 in the open position. Meanwhile, the second spring 94 allows the opening and closing plate 82 to slide to the left hand (closed position) with the operated member 92 to rotate the arm member 91 clockwise in a plane view.
The open retention mechanism 84 includes a held portion 90c provided in the operating member 90 to protrude backward, and a holding mechanism part 96 mounted in the case member 80 to be able to hold the held portion 90c. When the operating member 90 is pushed up to the backward movement limit position, the held portion 90c switches the holding mechanism part 96 from a non-active state to an active state. Next, when the operating member 90 is released from being pushed, the held portion 90c is held by the holding mechanism part 96 in an active state, so that the operating member 90 is held in an operation retention position a little before the backward movement limit position and the opening and closing plate 82 is held in the open position.
After that, when the operating member 90 is pushed from the operation retention position to the backward movement limit position again, the held portion 90c switches the holding mechanism part 96 from the active state to the non-active state. Next, when the operating member 90 is released from being pushed, the operating member 90 moves forward to the forward movement retention position, so that the opening and closing plate 82 is closed in the closed position.
The closed lock mechanism 85 includes a first engagement piece 97 provided in the operated member 92 to protrude upward; a second engagement piece 98 provided in the operating member 90 to protrude downward; and a pin escapement concave part 99 which is formed as a cutout and provided in the first elongate hole 91a of the arm member 91 (see
When the operating member 90 is in the forward movement retention position and the opening and closing plate 82 is in the closed position, the first engagement piece 97 is positioned on the left side of the second engagement piece 98 to approach and face the second engagement piece 98. Therefore, even if the player touches the opening and closing plate 82 with one hand to take out playing balls from the lower tray 8 with the hand so that a force is applied to open the opening and closing plate 82, the first engagement piece 97 engages with the second engagement pieces 98. At this time, if there is no force to push the operating member 90 backward, the opening and closing plate 82 is locked in the closed position.
Meanwhile, if the operating member 90 is pushed backward while the operating member 90 is in the forward movement retention position and the opening and closing plate 82 is in the closed position, the first engagement pin 90b of the operating member 90 is inserted into the pin escapement concave part 99 of the arm member 91 while the operating member 90 moves back a little. As a result, the driving force is not transmitted from the operating member 90 to the arm member 91, so that the arm member 91 is not rotated, and therefore the opening and closing plate 82 is not slid to the right side but is held in the closed position.
In this period of time, the second engagement piece 98 of the operating member 90 moves backward from the right side of the first engagement piece 97 of the operated member 92. After that, if the operating member 90 continues to be pushed backward, the driving force is transmitted from the operating member 90 to the arm member 91, so that the arm member 91 is rotated. As a result, the opening and closing plate 82 is slid to the right hand without engagement between the first engagement piece 97 and the second engagement piece 98. Here, in a case in which the opening and closing plate 82 is slid leftward from the open position to the closed position, the operating member 90 reaches the forward movement retention position after the opening and closing plate 82 reaches the open position. Therefore, the second engagement piece 98 moves to the right side of the first engagement piece 97 without collision with the first engagement piece 97.
The pachinko game machine 1 described above can produce the following effects. The tray unit 7 is provided with the entertainment button device 9 having the entertainment button 40 that the player can push, and the discharge device 10 provided below the entertainment button device 9 to discharge the playing balls accumulated in the lower tray 8b to the outside. The entertainment button device 9 is configured to allow the entertainment button 40 to be pushed from the upper side of the tray unit 7 and is placed on and supported by the discharge device 10.
The discharge device 10 is set in the unit main body 7a of the tray unit 7, and the entertainment button device 9 is placed on and supported by the discharge device 10. By this means, the unit main body 7a can accept the load (impact load) applied from the entertainment button 40 being pushed, from the entertainment button device 9 through the discharge device 10. Therefore, it is possible to omit a separate structure to firmly mount the entertainment button device 9 to the unit main body 7a, and consequently simplify the mounting structure for the entertainment button device 9 and the discharge device 10 in whole.
A large-sized entertainment button device 9 is provided with the large-sized entertainment button 40 moving up and down in a long stroke. The entertainment button device 9 is placed to approach the discharge device 10 below the entertainment button device 9. With this arrangement, the entertainment button device 9 can be placed on and supported by the discharge device 10. The arrangement and the mounting structure of the entertainment button device 9 and the discharge device 10 is appropriate for the large-sized entertainment button device 9.
The discharge device 10 is fixed to the lower part of the unit main body 7a of the tray unit 7 via the reinforcing metal plate 39. By this means, it is possible to improve the strength of the mounting structure of the discharge device 10. Moreover, the plate pieces 39a and 39b of the reinforcing metal plate 39 are placed on and attached to the surface of the plate supporting portions 7b1 and 7b2 formed in the lower part of the unit main body 7a. The discharge device 10 is attached to the reinforcing metal plate 39. Therefore, it is possible to disperse the load applied to the reinforcing metal plate 39, which is generated at the time the entertainment button 40 is pushed, and apply the load to the unit main body 7a.
Particularly, the entertainment button 40 of the entertainment button device 9 is large, and therefore the impact load generated at the time the entertainment button 40 is pushed is large. Moreover, the stroke of the entertainment button 40 being pushed from the protruding position to the pushed position is long, so that the impact load generated in the period of time for the stroke is likely to increase. However, with the mounting structure of the discharge device 10, it is possible to reliably prevent the mounting structure itself and the unit main body 7a from being damaging.
It is possible to easily mount the entertainment button device 9 and the discharge device 10 to the tray unit 7 by the following steps: coupling the entertainment button device 9 and the discharge device 10 to integrate them; inserting the integrated entertainment button device 9 and discharge device 10 into the device accommodating hole 7d of the unit main body 7a of the tray unit 7 from underneath; and mounting the discharge device 10 to the unit main body 7a. That is, it is possible to reduce the burden of installation of the entertainment button device 9 and the discharge device 10.
The entertainment button device 9 has the button case 50 including the peripheral wall 50a and the bottom wall 50b that accommodate the entertainment button 40 to be able to move up and down. The button case 50 includes a plurality of (three) outlets 51 to 53 that discharge foreign matters between the outer periphery of the entertainment button 40 and the peripheral wall 50a of the button case 50, to the outside of the button case 50.
By this means, it is possible to protect the entertainment button 40 by accommodating the entertainment button 40 to be able to move up and down in the button case 50. In addition, if the player spills beverage on the entertainment button 40 or over the vicinity of the entertainment button 40, and the liquid as a foreign matter enters and flows between the outer periphery of the entertainment button 40 and the peripheral wall 50a of the button case 50, the foreign matter is discharged from any of the plurality of outlets 51 to 53 of the button case 50. By this means, the entertainment button 40 can normally move up and down without the interference from the foreign matter.
A plurality of outlets 51 to 53 also serve as air inlets for the space enclosed by the entertainment button 40 and the button case 50 when the entertainment button 40 moves up and down. Therefore, with the plurality of outlets 51 to 53, it is possible to produce an effect of discharging the foreign matter between the outer periphery of the entertainment button 40 and the peripheral wall 50a of the button case 50 to the outside of the button case, as described above. Moreover, since the plurality of the outlets 51 to 53 also serve as the air inlets, it is possible to smoothly move the entertainment button 40 up and down. Particularly, thanks to the long stroke of the entertainment button 40, it is possible to produce a great effect of smoothly moving the entertainment button 40 up and down.
The bottom wall 50b of the button case 50 is provided to lean forward. The plurality of outlets 51 to 53 are formed in the lower edge of the peripheral wall 50a of the button case 50. The central outlet 51 is formed in the lower edge of the front part of the peripheral wall 50a of the button case 50. Therefore, the liquid as a foreign matter entering and flowing between the peripheral wall 42b of the button cover 42 and the peripheral wall 50a of the button case 50 is surely discharged from any of the plurality of outlets 51 to 53 directly, or, after reaching the bottom wall 50b of the button case 50 once.
The plurality of outlets 51 to 53 are formed apart from each other in the circumference direction in the lower edge of the peripheral wall 50a of the button case 50. Therefore, it is possible to ensure the coupling (connection) between the peripheral wall 50a and the bottom wall 50b of the button case 50, that is, the button case 50 is robustly constructed, and then it is possible to form the plurality of outlets 51 to 53 in the button case 50.
The button-up-and-down mechanism 60 includes: the button guide mechanism 61 that allows the entertainment button 40 to move up and down and that restricts the entertainment button 40 from rotating; the pair of biasing members 55 that biases the entertainment button 40 in the moving-up direction; the shaft member 68 that extends in the moving direction of the entertainment button 40; the rotating mechanism 70 that rotates the shaft member 68; the pair of engagement parts 76 provided in the entertainment button 40; and the pair of spiral guide parts 77 provided in the outer periphery of the shaft member 68. The pair of engagement parts 76 engages with the pair of spiral guide parts 77, respectively, while the entertainment button 40 is biased by the pair of biasing members 55, and the shaft member 68 is rotated by the rotating mechanism 70 so that the pair of spiral guide parts 77 moves the pair of engagement part 76 in the moving-down direction.
In this way, the rotating mechanism 70 rotates the shaft member 68, and therefore it is possible to smoothly move the entertainment button 40 up and down; allow the entertainment button 40 to desirably move up and down (stop temporarily, and move up and down repeatedly); and freely change the speed at which the entertainment button 40 moves up and down. As a result, it is possible to improve the effect of the entertainment of the game with the up-and-down movement of the entertainment button 40. Particularly, a large-sized entertainment button device 9 can be provided with the large-sized entertainment button 40 moving up and down in a long stroke.
The button-up-and-down mechanism 60 moves the entertainment button 40 between a predetermined normal operation position and the protruding position in which the entertainment button 40 protrudes upward from the normal operation position. The button-up-and-down mechanism 60 allows the entertainment button 40 to be pushed from any position including the normal operation position and the protruding position to the pushed position in which the entertainment button 40 retracts from the normal operation position.
That is, the button-up-and-down mechanism 60 can be configured not to interfere with the entertainment button 40 being pushed to the pushed position whenever the player pushes the entertainment button 40, for example, when the entertainment button 40 is held in the normal operation position or the protruding position, or when the entertainment button 40 is moved up and down by the button-up-and-down mechanism 60. Therefore, it is possible to ensure the degree of freedom of the entertainment button 40 being operated, and therefore improve operability.
The shaft member 68 is configured to be inserted into the entertainment button 40 from the base end side of the entertainment button 40. Therefore, the shaft member 68 can be provided in the entertainment button 40 not to be exposed to the outside. In addition, the entertainment button 40 is provided with the movable annular member 43b placed outside the outer periphery of the shaft member 68, and the pair of engagement parts 76 protrudes from the inner periphery of the movable annular member 43b to the shaft member 68 side to be able to engage with the pair of spiral guide parts 77. Accordingly, it is possible to reliably engage the pair of engagement parts 76 with the pair of spiral guide parts 77 to steadily move the entertainment button 40 up and down.
Each spiral guide part 77 includes the first spiral guide portion 77a and the second spiral guide portion 77b. The second spiral guide portion 77b continues to the front end of the first spiral guide portion 77a and has a greater angle of inclination than of the first spiral guide portion 77b. Therefore, when the rotating speed of the shaft member 68 is fixed, the speed at which the entertainment button 40 moves up and down is slower in a first case in which the pair of engagement parts 76 engages with the pair of first spiral guide portions 77a than in a second case in which the pair of engagement parts 76 engages with the pair of second spiral guide portions 77b. That is, the load on the shaft member 68 to move the entertainment button 40 up and down is smaller in the first case than in the second case.
In addition, the rotating mechanism 70 rotate and move the shaft member 68 up and down while the load on the shaft member 68 to move the entertainment button 40 up and down is reduced, that is, the pair of engagement parts 76 engages the pair of the first spiral guide portions 77a. By this means, it is possible to allow the entertainment button 40 to repeatedly move up and down smoothly. It is preferable to move the entertainment button 40 up and down in a position in which the entertainment button 40 moves up a little from the normal operation position. By this means, it is possible to perform an entertainment to excite the player about whether or not the entertainment button 40 moves to the protruding position.
The pair of smoothing guide parts 78 is formed on the outer periphery of the shaft member 68. The pair of smoothing guide parts 78 continues to the base ends of the pair of spiral guide parts 77 and extends in parallel with the plane orthogonal to the central axis of the shaft member 78. The pair of engagement parts 76 engages with the pair of smoothing guide parts 78 to hold the entertainment button 40 in the normal operation position. Accordingly, it is possible to reliably hold the entertainment button 40 in the normal operation position. In addition, when the button-up-and-down mechanism 60 moves the entertainment button 40 down, the pair of engagement parts 76 is smoothly moved from the pair of spiral parts 77 to the pair of smoothing parts 78, and therefore it is possible to smoothly move the entertainment button 40 down to the normal operation position.
With the pair of engagement parts 76 and the pair of spiral guide parts 77, the button-up-and-down mechanism 60 can more smoothly and stably move the entertainment button 40. Here, although an arrangement has been described where one pair of engagement parts 76 and one pair of spiral guide parts 77 are provided, three or more pairs are possible.
The present invention can be practiced with various configurations in addition to in the above-described embodiment as long as they do not deviate from the gist of the present invention. The entertainment button device and the discharge device according to the present invention, or the tray unit provided with them, are applicable to various pachinko game machines. In particular, the entertainment button device is applicable to various game machines such as a slot machine besides pachinko game machines.
