  According to these techniques, for example, by increasing the jackpot pattern, it is possible to give a player a chance to acquire a large amount of prize balls and contribute to the improvement of interest. However, the main points of the technology disclosed in these are changing the winning prize opening that is opened during the jackpot execution (Patent Document 1) or changing the winning prize opening that is opened according to the type of the jackpot (Patent Document 1). 2) In order to increase the number of jackpot patterns, it is not assumed that two (or two or more) big winning openings will be opened simultaneously. Therefore, if the jackpot pattern at that time can be inferred depending on which big winning opening (winning door) is opened, the player's interest (interest) may rapidly fade. In addition, since two (or more) large winning openings (winning doors) are not opened at the same time, an actuator (for example, a solenoid) for opening and closing the door is required for each large winning opening, and the structure is enlarged. To do. Furthermore, in order to prevent an illegal acquisition of a prize ball (commonly known as a goto action) by opening the winning door from the outside, a locking mechanism for the winning door is required for each large winning opening, and the locking mechanism becomes complicated.

  An object of the present invention is to open and close an opening / closing door as a so-called dummy door in conjunction with a winning door, thereby providing a winning expectation and continuously enhancing the interest in games, and simplifying and downsizing the structure and It is an object of the present invention to provide a variable winning device for a gaming machine that can save energy and prevent illegal acquisition of a prize ball, and a gaming machine using the same.

Means for Solving the Problems and Effects of the Invention

The variable prize winning device for gaming machines which is the premise of the present invention ,
It has a winning opening for introducing a game ball from a gaming area formed on the board surface of the gaming board to a winning area that faces the rear side opposite to the front side where the player is located, and is fixed to the gaming board A variable prize device for gaming machines,
Parallel to the game board and arranged so as to be rotatable around a first rotation axis that intersects the flow direction of the game ball, and stands up along the game board to close the winning opening and the game ball Displacement between a closed position where introduction into the winning area is impossible and an open position where the winning opening is opened by allowing the gaming ball to be introduced into the winning area by projecting in a crossing manner into the gaming area. A winning door,
A storage that is arranged to be rotatable about a second rotation axis parallel to the first rotation axis and stored along the game board on the downstream side and / or the lower side of the winning door. One or a plurality of opening / closing doors that are displaced to a position and a protruding position protruding in a crossing manner to the gaming area;
An actuator for rotationally displacing the winning door or the open / close door;
An interlocking mechanism for opening and closing the opening / closing door or the winning door in synchronization with the opening / closing operation of the winning door or the opening / closing door by the actuator;
The winning door and one door out of the door is accompanied to reversibly swings by the actuator, the other door to follow to reversibly swings through the interlocking mechanism.

In order to solve the above-mentioned problem, the variable prize winning device for gaming machine of the present invention is :
In order to introduce game balls from the game area formed on the board surface of the game board to the winning area facing the rear side opposite to the front side where the player is located, the flow direction is the vertical direction and the crossing direction is left and right. A variable winning device for a gaming machine having a winning opening in a direction (for example, formed in a rectangular shape) and fixed to the gaming board,
Parallel to the gaming board (for example, along the lower side of the winning opening) is arranged to be rotatable around a first rotation axis that extends in the left-right direction, and stands up along the gaming board to thereby win the winning opening Closed position where the game ball cannot be introduced into the winning area by closing and the winning opening is opened by projecting into the gaming area so as to allow the game ball to be introduced into the winning area A winning door (e.g., rectangular shape) that is displaced to the open position,
Above the winning door, the left-right direction is the longitudinal direction (for example, has a left-right width equal to the winning door), and is parallel to the first rotation axis (for example, along the upper side of the winning opening). A storage position (that is, a standing position) that is disposed around the second rotation axis extending in the left-right direction and that is stored along the game board, and a protrusion position that protrudes in a crossing manner to the game area (that is, a fall) Open / close door (for example, rectangular shape)
An actuator for rotating the winning door about the first rotation axis and displacing the winning door to the closed position and the open position;
An interlocking mechanism for storing and projecting the opening / closing door in synchronization with the closing / opening operation of the winning door by the actuator;
As the winning door swings and reversibly displaces between the closed position and the open position by the actuator, the open / close door follows the storage position and the protruding position via the interlocking mechanism. together reversibly swings between,
The open / close door has a plurality of ball passage holes penetrating in the thickness direction along the longitudinal direction, and each ball passage hole has the winning door in the open position when the open / close door is in the protruding position. The game ball introduced from the game area is opened so as to pass therethrough .

  In these variable award winning devices for gaming machines, the interlocking mechanism swings and opens and closes in conjunction with the winning door as a so-called dummy door (a pseudo door instead of the winning door), giving the game a sense of expectation for winning. The interest in can be dramatically and continuously increased. Further, since the winning door and the open / close door are operated in synchronization by the interlocking mechanism, the structure can be simplified, downsized, and energy can be saved without increasing the number of actuators. In addition, an interlocking mechanism is interposed between the winning door and the open / close door, so that if any one of the doors has a locking mechanism, the winning door (winning) Since the mouth) does not move to the open position, it is possible to prevent the illegal acquisition of the prize ball (got action).

  In addition, as illustrated in the specific embodiment, the winning opening, the winning door, and one open / close door (dummy door) are formed in a rectangular shape, have rotation axes parallel to each other, It is desirable that the winning doors are arranged close to each other so that the winning door is located below. According to this, further simplification, size reduction, and energy saving of the above-described structure can be achieved.

The opening / closing door is formed with a ball passing hole for penetrating in the thickness direction, communicating the gaming area to the winning area and winning the gaming ball,
When the open / close door is in the stowed position, the ball passage hole blocks the communication state between the game area and the winning area by a fixing member scheduled to be fixed to the game board, while the open / close door is in the protruding position. In some cases, it is desirable to maintain the game area and the winning area in communication.

  In this way, the ball opening hole for communicating the game ball in the game area with the winning area is formed in the open / close door located above, so that when the winning door is in the closed position, the game ball in the game area When the door is not obstructed and the winning door is in the open position, the door does not obstruct the winning of the game ball into the winning opening. In addition, when the winning door is in the open position, the game balls introduced from the gaming area to the open / close door are introduced into the winning area through the ball passage hole, so that the player can acquire a large number of winning balls in a short time. can do.

  Specifically, the ball passage holes are arranged in a plurality of window holes along the left-right direction of the open / close door, and when the open / close door is in the protruding position, each ball pass hole is a winning door in the open position. The game balls introduced from the game area are opened so as to be able to pass through the upper part of the game area, and the game balls that have passed through the ball passage holes can be received by the prize door and introduced into the prize area. When the winning door is in the open position, that is, when the open / close door is in the projecting position (falling position), the game balls introduced from the game area pass through the ball passage hole of the open / close door and are received by the winning door, and the winning area Therefore, it is possible to prevent the clogging of the ball at the opening / closing door and to smoothly win the game ball without any delay.

  Further, when the opening / closing door is in the storage position, each ball passage hole is closed by the fixing member, and the front surface of the opening / closing door and the front surface of the fixing member are arranged to be flush with each other. be able to. When the open / close door is in the stowed position (standing position), the game ball in the game area flows down without flowing into the ball passage hole, and flows down the front side of the winning door in the closed position. The game ball can flow smoothly without any delay. In addition, since the surface of the open / close door and the surface of the fixing member are flush with each other, the catch is reduced, and an illegal act of opening the open / close door from the outside can be prevented.

  At this time, if the front surface of the open / close door is arranged so as to be flush with the front surface of the winning door in the closed position, the game ball can flow down the game area more smoothly. Can do.

  By the way, the interlocking mechanism functions to hold the opening / closing door in the storage position when the winning door is in the closed position, and to hold the opening / closing door in the protruding position when the winning door is in the open position. Thus, when the winning door is in the closed position, the open / close door is held in the stowed position (standing position) by the interlocking mechanism. Therefore, even if the winning door is opened by operating the open / close door from the outside, Without moving to the open position, cheating can be prevented.

Specifically, the interlocking mechanism described above is
A first recess is formed at the front end of the opening / closing door so as to be swingable around the second rotation axis and can be fitted with a protrusion protruding parallel to the first rotation axis from the winning door. A swing arm;
A second swinging arm that is swingably attached to a plunger of a solenoid as an actuator arranged orthogonally to the game board, and has an inner surface that can be brought into contact with the outer surface of the first swinging arm at the tip portion. ,
When the solenoid is energized to displace the winning door to the open position, the second swing arm swings with the immersion of the plunger, and the inner surface of the tip of the second swing arm is the first swing arm. By abutting the outer surface and swinging the first swing arm in the opposite direction to the second swing arm, the recess is removed from the protrusion, and the winning door is moved to the first position (in some cases, by moving its center of gravity). While rotating about the rotation axis and displacing to the open position, the open / close door is rotated about the second rotation axis (in some cases due to movement of its center of gravity) and displaced to the protruding position.

  Thus, when the plunger is immersed by the excitation of the solenoid, the inner surface of the tip of the second swing arm comes into contact with the outer surface of the first swing arm, so that the recess of the first swing arm is separated from the projection of the winning door. The winning door can be displaced to the open position by being separated. Accordingly, the lock mechanism of the winning door can be simply configured by the protrusion of the winning door and the recess of the second swing arm, and by releasing the engagement of the lock mechanism, the winning door is closed from the closed position to the open position. Displacement can be easily achieved.

Further, the second swing arm of the interlocking mechanism is formed with a bulging portion that can be pressed from above against the projection of the winning door,
When the solenoid is demagnetized to displace the winning door to the closed position, the second swing arm swings with the protrusion of the plunger, and the bulging part pushes down the protrusion to make the winning door the second swing arm. By rotating in the reverse direction, the protrusion is fitted into the recess to integrate the winning door and the first swing arm, and the winning door is rotated around the first rotation axis and displaced to the closed position. The opening / closing door rotates around the second rotation axis and is displaced to the storage position.

  Thus, when the plunger protrudes due to the demagnetization of the solenoid, the bulging part of the second swing arm pushes down the protrusion of the winning door, so that the protrusion of the winning door is fitted into the recess of the first swing arm, The winning door can be displaced to the closed position. Accordingly, the lock mechanism of the winning door can be simply configured by the first and second swing arms, and by disengaging the locking mechanism, the displacement of the winning door from the open position to the closed position can be easily achieved.

Furthermore, the interlocking mechanism is rotatable about a third rotation axis that is arranged in parallel to the first rotation axis with respect to the winning door, and parallel to the second rotation axis with respect to the opening / closing door. Both ends of the connecting link are spanned so as to be rotatable around the fourth rotation axis arranged in a shape,
In a plane orthogonal to the first to fourth rotation axes, a line segment connecting the third rotation axis and the fourth rotation axis is a line segment connecting the first rotation axis and the second rotation axis. And are arranged in parallel.

  In this way, the connecting link constitutes a parallel crank mechanism (parallel link mechanism) together with a line segment connecting the first rotation axis and the second rotation axis, so that the displacement between the winning door closing position and the opening position is determined. Can be smoothly transmitted to the displacement between the storage position and the protruding position of the door.

Therefore, in order to solve the above problems, the gaming machine of the present invention is:
The variable winning device for gaming machine as described above is fixedly arranged on the gaming board.

  As a result, it is possible to realize a gaming machine having an interesting board structure, to simplify the structure, to reduce the size and to save energy, and to prevent illegal acquisition of prize balls.

(Example)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view illustrating a pachinko machine equipped with a variable prize device for gaming machines according to the present invention (hereinafter also simply referred to as a prize device), and FIG. 2 shows an example of a prize device according to the present invention. FIG. 3 is a front view and a perspective view when the lower door is in the open position. 4 is a perspective view showing the main part of FIG. 2, and FIG. 5 is a perspective view showing the main part of FIG. As shown in FIG. 1, on the board surface 2a (front surface) of the game board 2 of the pachinko machine 1 (game machine), a substantially left half circumference is partitioned by two inner and outer firing rails 2b, and a game area 2c having a substantially circular shape as a whole. Is formed. A liquid crystal display unit 3 is mounted in the center of the game area 2c, and a winning device 4 is disposed below the liquid crystal display unit 3 (lower center of the game area 2c). Between the liquid crystal display unit 3 and the winning device 4, an electric tulip-type start winning port 8 formed by a pair of rotating blade pieces 8 a and 8 a is disposed.

  As shown in FIGS. 2 and 3, the winning device 4 is configured to include a base plate 5 for fixing to the game board 2 (see FIG. 1). When the direction is the left-right direction, it has a large winning opening 5b (winning opening) formed in a rectangular shape with the left-right direction as the longitudinal direction. Therefore, the game ball launched from the launch rail 2b passes from the game area 2c formed on the board surface 2a of the game board 2 through the special winning opening 5b and is on the rear side (the side opposite to the front side where the player is located). ) Is introduced into the winning area 5c (see FIGS. 1 and 3A).

  As shown in FIGS. 4 and 5, the winning device 4 is rotatable above the rectangular winning door 5 b and a rectangular lower door 10 (winning door) that is rotatably fitted in the winning winning port 5 b. A rectangular upper door 20 (opening / closing door) disposed in the upper door 20, a solenoid 30 (actuator) for rotationally displacing the lower door 10, and the upper door 20 in synchronization with the rotational displacement of the lower door 10 by the solenoid 30. And an interlocking mechanism 40 for rotationally displacing the lens.

  The lower door 10 is arranged in parallel with the game board 2 (see FIG. 1) so as to be rotatable around a first rotation axis O1 extending in the left-right direction along the lower side of the special winning opening 5b. Then, a standing position (FIGS. 2 and 4) that makes it impossible to introduce the game ball into the winning area 5c by standing along the game board 2 so as to close the special winning opening 5b and intersect with the gaming area 2c. By projecting in a substantially orthogonal shape, for example, the large winning opening 5b is opened and the game ball is displaced to an open position (FIGS. 3 and 5) that allows the game ball to be introduced into the winning area 5c.

  The upper door 20 has a left-right width equal to that of the lower door 10 above the lower door 10, and is parallel to the first rotation axis O1 and extends in the left-right direction along the upper side of the big prize opening 5b. It arrange | positions so that rotation around the axis line O2 is possible. Then, a storage position (that is, a standing position; FIGS. 2 and 4) stored along the game board 2 (see FIG. 1) and a protruding position (for example, substantially orthogonal) protruding to the game area 2c ( That is, it is displaced to the lying position; FIGS.

  The upper door 20 has a ball passage hole 21 penetrating in the thickness direction (front-rear direction). When the upper door 20 is in the storage position (stand-up position), the ball passage hole 21 is blocked from communicating with the game area 2c and the winning area 5c by the lens 6 (fixing member) fixed to the base plate 5. (FIG. 2). On the other hand, when the upper door 20 is in the protruding position (falling position), the ball passage hole 21 maintains the game area 2c and the winning area 5c in communication with each other and allows the gaming ball to win the winning area 5c (FIG. 3). .

  Specifically, the ball passage holes 21 are arranged in a plurality of (for example, four) window holes along the left-right direction (longitudinal direction) of the upper door 20, and the lens 6 corresponds to each ball passage hole 21. In this way, the same number (4 pieces) is formed. Therefore, when the upper door 20 is in the protruding position, each ball passage hole 21 is opened above the lower door 10 in the open position so that the game ball introduced from the game area 2c can pass (FIG. 3 ( b)). That is, the upper door 20 (ball passage hole 21) functions as a dummy door (dummy opening) which is a pseudo door (opening). Since the game ball that has passed through the ball passage hole 21 in this way is received by the inner surface of the lower door 10 in the open position, it passes through the big winning opening 5b and is smoothly introduced into the winning area 5c without any delay.

  When the upper door 20 is in the storage position, each ball passage hole 21 is closed by the corresponding lens 6, and the front surface of the window frame 22 of the upper door 20 and the front surface of the lens 6 are flush with each other. Are arranged in a shape. Moreover, these surfaces are arrange | positioned so that it may become flush with the surface of the front side of the lower door 10 in a closed position. As a result, the game ball smoothly flows down the game area 2c without clogging the ball at the upper door 20 or the lower door 10, and it is easy to prevent an illegal act of rotating the upper door 20 or the lower door 10 from the outside. .

  The solenoid 30 is arranged to intersect (for example, orthogonal) with the game board 2 (see FIG. 1), and the lower door 10 is rotated around the first rotation axis O1 to close (FIG. 4) and open ( 5). In addition, the interlocking mechanism 40 synchronizes with the displacement of the lower door 10 between the closed position and the open position by the solenoid 30, and moves the upper door 20 between the storage position (FIG. 4) and the protruding position (FIG. 5). Displace with.

  In this way, in the winning device 4, the lower door 10 is reversibly oscillated and displaced between the closed position (see FIGS. 2 and 4) and the open position (see FIGS. 3 and 5) by the solenoid 30. Accordingly, the upper door 20 swings and reversibly displaces between the storage position (see FIGS. 2 and 4) and the protruding position (see FIGS. 3 and 5) via the interlocking mechanism 40.

  2 and 3, a pair of left and right standing walls 5a are integrally formed on the base plate 5, and the standing walls 5a are respectively erected from both longitudinal edges of the big prize opening 5b toward the front side. . The standing wall 5a prevents the game ball from spilling out into the game area 2c from both longitudinal ends of the lower door 10 displaced to the open position. Reference numeral 7 denotes a proximity switch (detection sensor; winning ball detecting means) for detecting a gaming ball introduced from the gaming area 2c (see FIG. 1) through the big winning opening 5b into the winning area 5c.

  Next, the operating state of the winning device 4 is shown in FIGS. 6 to 11 and the rotational displacement of the upper door 20 and the lower door 10 will be described in detail. The interlocking mechanism 40 of the winning device 4 holds the upper door 20 in the storage position (standing position) when the lower door 10 is in the closed position (FIG. 6), and projects the upper door 20 when the lower door 10 is in the open position. It is held at the position (falling position) (FIG. 9).

  Specifically, the interlocking mechanism 40 is disposed on one end side (for example, the left side) of the winning device 4 so as to partially overlap in the left-right direction behind the upper door 20 and the lower door 10. One swing arm 41 and a second swing arm 42 are included (see FIGS. 4 and 5). The first swing arm 41 has an upper end attached to be swingable around the second rotation axis O2 of the upper door 20 and is parallel to the first rotation axis O1 from the lower end rear edge of the lower door 10. A notch-like recess 41a (locking mechanism) that can be fitted to the protrusion 11 (locking mechanism) that protrudes into the opening is formed on the front side of the tip (lower end).

  The second swing arm 42 is swingably attached to the plunger 31 of the solenoid 30 and also has a contact inner surface 42e (contactable) with the contact outer surface 41b (outer surface) at the tip of the first swing arm 41. The inner surface is formed at the tip (lower end). More specifically, a plunger head 31a is fixed to the plunger 31 of the solenoid 30, and a slider 32 is integrally formed with the plunger head 31a. Therefore, the second swinging arm 42 has a pin 32a (a first engaging portion) formed on the upper edge of the second swinging arm 42 so as to protrude from the upper end surface of the slider 32 in parallel with the first rotation axis O1. The first engaging portion is inserted (engaged) so as to be rotatable. In addition, the second swing arm 42 is supported by a casing 42 (not shown) so that the pin 42b (second engagement portion) protruding parallel to the first rotation axis O1 at the upper and lower intermediate portions can only rotate. A long hole 32b (second engagement portion) formed in the front-rear direction at the upper and lower intermediate portions of the slider 32 is inserted and held (engaged) so as to be slidable back and forth.

  Accordingly, when the plunger 31 of the solenoid 30 is retracted rearward, the second swinging arm 42 is pulled backward by the pin 32a of the slider 32 and the one side (see FIG. Rotate 6 (a) counterclockwise. Similarly, in the second swing arm 42, when the plunger 31 of the solenoid 30 protrudes forward, the upper notch portion 42a is pushed forward by the pin 32a of the slider 32, and the other side ( It rotates in the clockwise direction in FIG.

  Note that a compression coil spring 31b (biasing member) for biasing the plunger head 31a (plunger 31) in the protruding direction is inserted between the solenoid 30 and the plunger head 31a in a form inserted into the plunger 31. It is disguised.

  Further, the interlocking mechanism 40 is provided with a connecting link 43 on the other side (for example, the right side) in the left-right direction of the winning device 4 (see FIGS. 4 and 5). The connection link 43 has a lower end that can rotate about a third rotation axis O3 that is arranged in parallel to the lower door 10 behind the first rotation axis O1, and an upper end. Are wound around the upper door 20 so as to be rotatable around a fourth rotation axis O4 arranged in parallel behind the second rotation axis O2. Therefore, for example, in FIG. 6B, a line segment L2 connecting the third rotation axis O3 and the fourth rotation axis O4 is a line segment L1 connecting the first rotation axis O1 and the second rotation axis O2. And a parallel crank mechanism (parallel link mechanism).

  In the winning device 4, when the solenoid 30 is excited in the closed position (FIG. 6) of the lower door 10 in order to displace the lower door 10 to the open position (FIG. 9), the second swing is caused by the immersion of the plunger 31. The moving arm 42 swings to one side (counterclockwise in FIG. 6A). At this time, the contact inner surface 42e of the second swing arm 42 contacts and pushes up the contact outer surface 41b of the first swing arm 41, so that the first swing arm 41 is in the reverse direction of the second swing arm 42 (FIG. 6). (A), swings clockwise in FIGS. 7 (a) and 8 (a).

  8A, when the recess 41a of the first swing arm 41 is detached from the protrusion 11 of the lower door 10, the lower door 10 is moved around the first rotation axis O1 by the center of gravity movement thereof. It rotates in the direction opposite to 42 (clockwise in FIG. 8A) and is displaced to the open position (FIG. 9). The connecting link 43 changes the displacement of the lower door 10 from the closed position (FIG. 6) to the open position (FIG. 9), and the displacement of the upper door 20 from the storage position (FIG. 6) to the protruding position (FIG. 9). It can be transmitted smoothly.

  Further, the second swing arm 42 of the interlocking mechanism 40 is formed with a bulging portion 42 c that can be pressed from above against the protrusion 11 of the lower door 10. In the winning device 4, when the solenoid 30 is demagnetized in the open position (FIG. 9) of the lower door 10 in order to displace the lower door 10 to the closed position (FIG. 6), the second swing is caused by the immersion of the plunger 31. The moving arm 42 swings to the other side (clockwise in FIG. 9A). At this time, the bulging portion 42c of the second swing arm 42 pushes down the protrusion 11 of the lower door 10, so that the lower door 10 is in the opposite direction to the second swing arm 42 (FIGS. 9A and 10A). 11), and the first swing arm 41 rotates in the same direction as the second swing arm 42 (FIGS. 9A, 10A, 11A). ) (Clockwise).

  11A, when the protrusion 11 of the lower door 10 is fitted into the recess 41a of the first swing arm 41, the lower door 10 is integrated with the first swing arm 41, and the lower swing and the first swing arm 41 are integrated. The arm 41 rotates in the same direction (counterclockwise in FIG. 11A). The lower door 10 rotates about the first rotation axis O1 in the opposite direction to the second swing arm 42 (counterclockwise in FIG. 11A) and is displaced to the closed position (FIG. 6). The connecting link 43 changes the displacement of the lower door 10 from the open position (FIG. 9) to the closed position (FIG. 6), and the displacement of the upper door 20 from the protruding position (FIG. 9) to the storage position (FIG. 6). It can be transmitted smoothly. In addition to the bulging portion 42c, the second swing arm 42 can be pressed from above against the upper protrusion 23 that protrudes in parallel with the second rotation axis O2 from the lower end rear edge portion of the upper door 20. The upper bulging portion 42d is formed so as to protrude forward, and assists the pressing action by the bulging portion 42c.

  The outline of the operation of the winning device 4 on the game board 2 will be described with reference to FIGS. When a game ball wins the start winning opening 8, a winning / no-win lottery is executed, and if the lottery result is a big win, a big hit symbol (for example, a “777” double eye) is displayed on the liquid crystal display unit 3. Further, the solenoid 30 of the winning device 4 is excited, the lower door 10 is rotated around the first rotation axis O1 and displaced to the open position (FIG. 3), and the upper door 20 is moved to the second rotation axis O2. It rotates around and is displaced to the protruding position (FIG. 3). Then, when the proximity switch 7 detects a predetermined number (for example, 10) of winnings to the big winning opening 5b or when a predetermined time (for example, 30 seconds) has passed, the lower door 10 is moved to the closed position (FIG. 2). In addition to the displacement, the upper door 20 is displaced to the storage position (FIG. 2). This is defined as one round (1R), and a predetermined number of rounds (for example, 15R) is repeated, and the player can acquire a large amount of prize balls during this period.

  At this time, the interlocking mechanism 40 swings and opens the upper door 20 as a dummy door in conjunction with the lower door 10, so that a winning expectation is given and the interest in the game is dramatically and continuously increased. Further, since the lower door 10 and the upper door 20 are operated in synchronization by the interlocking mechanism 40, the structure can be simplified, downsized, and energy can be saved without increasing the number of solenoids 30. Furthermore, since the projection 11 and the recess 41a are arranged as a locking mechanism in the interlocking mechanism 40 between the lower door 10 and the upper door 20, the lower door 10 ( The big prize opening 5b) does not move to the open position, and it is possible to prevent an illegal acquisition of a prize ball (got action).

  In the interlocking mechanism 40, the cutout portion 42a and the pin 32a constituting the first engagement portion can be replaced with each other. Similarly, the long hole 32b and the pin 42b constituting the second engaging portion can be implemented by being interchanged with each other.
