The present invention relates to a winning device for a ball game machine, and in particular, a game ball that falls by moving a protruding member from a retreat position substantially flush with the game board surface to a protruding position protruding forward is placed on the upper portion thereof. It relates to a shutter-type winning device that rolls along.

The ball gaming machine is provided with a winning device such as a large winning opening that makes it easy to win a gaming ball. For example, the large winning opening is closed so as not to win a game ball at normal times, and it is easy to win a game ball when it is released under specific conditions. As a result, it is possible to make a state advantageous for the player who pays out the prize ball when the game ball is won.

For example, Patent Document 1 discloses a shutter-type winning device among the winning devices. The winning device rotates around a plunger driven in the vertical direction by a solenoid, a first operating member that moves up and down in conjunction with the plunger, and a rotation axis that extends in the horizontal direction as the first operating member moves up and down. The second actuating member is provided with a flat plate-shaped opening / closing member (shutter) that slides back and forth between the open position and the closed position as the second actuating member rotates. By sliding the opening / closing member to the open position by driving the solenoid, the big winning opening under it can be opened. The first actuating member is provided with a lock portion that protrudes rearward, and when an attempt is made to illegally move the opening / closing member from the closed position to the open position, the second lock portion of the second actuating member abuts and prevents the movement. However, it is said that cheating can be prevented.

By the way, since such a shutter-type winning device is used for a gaming machine having a limited space, it has been proposed to make it compact.

For example, Patent Document 2 discloses that a shutter-type winning device suppresses bulkiness. A slide member that slides left and right by a solenoid is engaged with one arm portion of an L-shaped interlocking member that is rotatable in a horizontal plane and has a bent portion at the center of rotation, and the other arm portion of the interlocking member. Is engaged with a plate-shaped ball derivative (shutter) that can slide back and forth. Then, the interlocking member is rotated so as to move one arm portion left and right via the slide member by the drive of the solenoid, and the other arm portion is moved in the front-rear direction to slide the sphere derivative back and forth. The ball derivative guides the game ball to the side winning opening when it is in the guiding position protruding forward, and drops the game ball downward when it is in the passing position where it is evacuated to the rear. Here, it is assumed that all the members displaced by the drive of the solenoid are displaced in the horizontal direction and arranged so as to overlap the arrangement region of the sphere derivative in the left-right and front-back directions to suppress the bulkiness in the left-right and front-back directions. There is.

A shutter-type winning device as an embodiment according to the present invention will be described with reference to FIGS. 1 to 5.

As shown in FIG. 1, the shutter-type winning device 1 is, for example, a winning device provided with a large winning opening (attacker) installed on the right side of the board in a ball game machine that promotes winning of a gaming ball by hitting right during a jackpot operation. Can be used as. That is, the start winning opening 2 for opening the big winning opening when the game ball is won during the jackpot operation, the entrance 3 for accepting the game ball entering from the upper right side, and the game entering the entrance 3. It includes a passage 4 having an inclination that lowers the left side so as to guide the ball toward the left side (center side of the board), and a front plate 5 that is a front wall that divides the front of the passage 4. The front plate 5 is missing in front of the right side portion of the passage 4, making it easier for the player to see the game ball that has entered the passage 4.

Referring to FIG. 2 together, a shutter member 10 having a rectangular surface 10a whose left and right directions are longitudinal directions is provided on the upper side so as to be continuous with the bottom plate portion 4a that partitions the bottom surface of the passage 4. The shutter member 10 is a projecting member that is held by the attacker base 12 so as to be slidable back and forth and can project from the base surface 12a of the attacker base 12. That is, when the shutter member 10 is in a protruding position protruding forward from the base surface 12a of the attacker base 12, the game ball guided from the passage 4 can be further guided to the left side on the rectangular surface 10a and discharged from the discharge port 6. .. On the other hand, when the shutter member 10 is retracted rearward and its tip is placed at a position substantially flush with the base surface 12a of the attacker base 12, the game ball guided from the passage 4 is placed on the rectangular surface 10a. It can be dropped to the front side without being led to the winning passage 13 formed in the attacker base 12.

The attacker base 12 is fixed so as to be inserted in the front-rear direction through the base plate 11 for attaching the shutter type winning device 1 to the game board 40 (see FIG. 6). Further, the base plate 11 is attached to the game board 40 (see FIG. 6) so that the front surface of the base plate 11 and the base surface 12a of the attacker base 12 are substantially flush with the game board surface which is the front side surface of the game board 40. It is arranged. That is, the protruding position is a position where the shutter member 10, which is a protruding member, is projected from the surface of the game board by a distance larger than the radius of the game ball.

The winning passage 13 has an inclination that lowers the left side like the rectangular surface 10a, and the falling game ball can be guided to the winning opening 14 at the left end. That is, the protruding position of the shutter member 10 is the closing of the attacker, and the retreating position of the shutter member 10 is the opening of the attacker.

Further below the winning passage 13 of the attacker base 12, a solenoid 21 for obtaining a driving force for sliding the shutter member 10 is housed. The mechanism driven by the solenoid 21 will be described later.

As shown in FIG. 3, in order to slide the shutter member 10 and project it forward, the attacker base 12 has a window portion 12c, which is an opening corresponding to the front shape of the shutter member, on the base surface 12a. There is. Further, the shutter member 10 is provided with a plurality of ridges 10b extending in the front-rear direction on the back surface thereof and other portions except for the rectangular surface 10a. The attacker base 12 is provided with a groove 12b extending in the front-rear direction corresponding to each protrusion 10b of the shutter member 10, and can stabilize the orientation of the shutter member 10 at the time of sliding. As a result, the orientation of the shutter member 10 can be stabilized and the operation can be smoothed.

As shown in FIGS. 4 and 5, the shutter member 10 includes a first pin body 10c that projects downward from the central back surface of the rectangular surface 10a in the left-right direction. A rotating member 30 is connected to the first pin body 10c so as to rotate around a rotating shaft Z extending in a substantially vertical direction. The rotating member 30 includes a drive arm 31 extending to the left from the rotating shaft Z and an extending arm 32 extending forward, each of which is rotatable in a horizontal plane. The tip of the drive arm 31 has a bifurcated tip portion 31a that opens to the left, and the first pin body 10c is slidably held in the left-right direction between the bifurcations of the tip portion 31a. Further, the extension end portion in front of the extension arm 32 is provided with a second pin body 32a that extends downward and engages with the connecting member 23. The second pin body 32a is loosely inserted into a groove 24 extending in the front-rear direction provided in the connection member 23, and is slidably held in the front-rear direction with respect to the connection member 23. The connecting member 23 is attached to the plunger 22 of the solenoid 21 and can be driven by the solenoid 21 in the left-right direction in parallel with the game board surface 40a (see FIG. 6). Further, in the rotating member 30, the drive arm 31 and the extension arm 32 form an acute angle with each other.

Here, the rotation shaft Z is provided on the right side of the rectangular surface 10a, that is, on the side of the window portion 12c corresponding to the outer shape of the shutter member 10 in the front view. Further, the rotation shaft Z is provided behind the game board surface 40a (see FIG. 6) of the game board 40 which is substantially flush with the base surface 12a of the attacker base 12. Since the drive arm 31 that rotates around the rotation axis Z extends to the first pin body provided at the center of the rectangular surface 10a in the left-right direction, its length is at least the length in the left-right direction of the rectangular surface 10a. It will be more than half of. Further, a rotation shaft Z is provided on the right side of the rectangular surface 10a on the side where the inclination is high so as to obtain a wider space for a member arranged below the shutter member 10 such as the drive arm 31. ..

Next, the operation of the shutter member 10 of the shutter type winning device 1 will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5 , the shutter member 10 is in a protruding position protruding forward (lower than the paper surface) from the base surface 12a of the attacker base 12. At this time, the solenoid 21 projects the plunger 2 2 to the right and positions the connecting member 23 away from the right side.

When the plunger 22 is pulled to the main body side (left side) of the solenoid 21 by the solenoid 21, the connecting member 23 attached to the plunger 22 is also pulled to the left side. Then, the second pin body 31a held in the groove 24 provided in the connecting member 23 is pulled to the left side, and the rotating member 30 is rotated clockwise together with the extension arm 32 in a top view. Along with this, the drive arm 31 of the rotating member 30 also rotates so as to move its tip portion 31a rearward (above the paper surface). As a result, the shutter member 10 moves to the rear retreat position together with the first pin body 10c held by the tip portion 31a.

Further, when the shutter member 10 is returned to the protruding position, the operation in the opposite direction to this may be performed. That is, of both arms of the rotating member 30 forming an acute angle, the extension arm 32 is moved to a position close to perpendicular to the game board surface 40a (clockwise on the paper), and the tip portion 31a of the drive arm 31 is moved forward. It is moved and the shutter member 10 is moved to the protruding position.

In this way, the tip portion 31a of the drive arm 31 can be pendulum-moved in the horizontal plane to move the shutter member 10 back and forth together with the first pin body 10c.

As described above, the drive arm 31 and the extension arm 32 have an acute angle with each other, and when they are in the protruding position, the rotation axis Z is set with respect to the second pin body 32a which is the extension end of the extension arm 32. It will not be positioned on the right side beyond that. Similarly, when in the retreat position, the tip portion 31a of the drive arm 31 is not arranged rearward beyond the rotation axis Z. That is, even if the pendulum movement of the rotating member 30, each arm of the rotating member does not protrude to the right or rear of the rotating shaft Z, and the moving range of the drive arm 31 and the extension arm 32 can be narrowed.

As shown in FIG. 6A, in the protruding position in such an operation, the rectangular surface 10a of the shutter member 10 is a passage that guides the game ball to the left discharge port 6 on the rectangular surface 10a when the shutter member 10 is in the protruding position. Must be the bottom. Therefore, the distance of the rectangular surface 10a protruding from the base surface 12a at the protruding position is at least larger than the radius of the game ball. Here, the front end (lower side of the paper surface) of the rectangular surface 10a is arranged so as to provide a gap d between the rectangular surface 10a and the front plate 5 which is the front wall. In order to prevent the game ball from being fitted into the gap d, it is preferable to make the gap d smaller than 1/2 the diameter of the game ball. By providing such a gap d, the distance between the protruding position and the retreating position of the shutter member 10 can be reduced.

As shown in FIG. 6B, in the retreat position, the rectangular surface 10a of the shutter member 10 is in front of the base surface 12a of the attacker base 12, which is a surface that divides the front end thereof behind the passage of the game ball. It is projected to. The protrusion dimension due to such protrusion is set to less than 1/2 of the diameter of the game ball so that the game ball is surely dropped in front of the shutter member 10a. Further, the gap between the protrusion and the front plate 5 is set to exceed the diameter of the game ball. In this way, by projecting the rectangular surface 10a from the base surface 12a at the retreat position, the distance between the projecting position and the retreat position of the shutter member 10 can be further reduced.

As described above, in the shutter type winning device 1, the rotation shaft Z is provided on the side portion of the window portion 12a to increase the length of the drive arm 31. As a result, the rotation angle of the rotating member 30 with respect to the moving distance of the shutter member 10 back and forth is reduced. That is, the distance between the protruding position and the retracting position of the shutter member 10 can be increased while reducing the rotation angle of the rotating member 30, and as a result, the shutter type winning device 1 can be made compact. For example, according to the shutter type winning device 1, it can be attached so as not to protrude behind the game board 40.

As shown in FIG. 7, the groove 24 of the connecting member 23 is formed with a step 24a on the side surface of the rectangular surface 10a side (left side) so as to narrow the groove 24 toward the rotation axis Z side. .. Then, when the shutter member 10 is positioned at the protruding position, the second pin body 32a is housed in the step 24a. Here, the second pin body 32a is on the rectangular surface 10a side (left side) with respect to the rotation shaft Z. Therefore, even if an external force is applied so as to push the shutter member 10 backward, the rearward movement of the second pin body 32a is prevented by the step 24a of the connecting member 23, and the rotating member 30 rotates clockwise. Can be prevented. That is, it is possible to prevent fraudulent acts such as pushing the shutter member 10 in the protruding position and moving it to the shelter position without increasing the number of parts and sacrificing the dimensions.

In the above embodiment, the winning opening 14 is provided under the shutter member 10, and the discharging port 6 is provided on the left side where the game ball is rolled on the rectangular surface 10a to make it out of place. It is also possible to provide a shutter at the position of the mouth 14 and a winning opening at the position of the discharge hole 6 so that the shutter and the winning are at opposite positions. Furthermore, both can be given different prize balls and different benefits as prize openings.

Although the representative examples according to the present invention have been described so far, the present invention is not necessarily limited to this, and those skilled in the art can vary without departing from the gist of the present invention or the scope of the attached claims. Alternative and modified examples of can be found.
