DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a winning device for a pachinko machine.

[Prior Art] As a winning device for a pachinko machine, for example, a ball holder such as a movable piece or an opening/closing plate that can be converted into a first state in which it is difficult to receive hit balls and a second state in which it is easy to accept hit balls on the front surface of a mounting board is used. In addition to providing a member, a general winning hole and a special prize winning hole are provided for winning the balls received by the ball receiving member, and the balls received into the special prize winning hole cause the ball receiving member to enter the ball in a manner regulated by a predetermined time or number of times. Devices that can be set to state 2 are known.

[Problems to be solved by the invention] However, in the conventional system, the special prize winning hole is fixedly provided and is placed in a position where it is difficult for the hit ball to enter the special prize winning hole. There are few opportunities to win prizes, which does not provide sufficient satisfaction to players. For this reason, the phenomenon of customer loss has been increasing recently. On the other hand, if a game center were to make it easy for balls to enter the special prize opening, there would be a risk that a large number of players would win a large number of prize balls in a short period of time, making the business unsustainable. , countermeasures are strongly requested.

[Object of the Invention] Therefore, an object of the present invention is to attract the interest of players by making it possible to move the special prize winning opening from a position where it is difficult to enter the ball to a position where it is easy to enter based on predetermined game conditions.

Further, a protruding member 44 is formed in the recessed chamber 9 above the sliding member 16. This protrusion member 44 impeller 10a, 10b
The hit ball accepted by
This makes it difficult to enter.

The impellers 10a and 10b have a plurality of blades 10 on their outer peripheries at intervals that allow them to receive a ball. These impellers 10a and 10b are in the first state in which it is difficult to accept balls when they rotate outwardly, so they do not accept the balls between the blades 10 and guide them from the side to the bottom of the game board, and when they rotate inwardly, the balls are guided downward from the game board. As a second state in which it is easy to accept the ball, the ball is held between the blades 10 and won into the general winning openings 11a to 11c or the special winning opening 14. Moreover, the impeller 10a, 1
0b has support shafts 22, 22 protruding from the center, and these support shafts 22, 22 have guide holes 23, 23 drilled in the mounting board 6 and guide holes drilled in the support plate 24 at the rear of the mounting board 6. 25, 25. Also,
Small diameter gears 27a, 27 are provided at the ends of the support shafts 22, 22.
b are fixed respectively.

A forward/reverse rotation motor 28 for rotating the impellers 10a and 10b is mounted on the support plate 28'. A drive gear 30 is fixed to the output shaft 29 of the forward/reverse rotation motor 28 , and a floating gear 31 having the same diameter that meshes with the drive gear 30 is mounted on a shaft 32 projecting from the support plate 24 . A small diameter gear 27a is meshed with the drive gear 30, and a small diameter gear 27b is meshed with the floating gear 31.

Further, an impeller moving means 3 is provided on the back side of the mounting board 6.
2 is installed. This impeller moving means 32 is composed of a solenoid 33 attached to the support plate 24 and link members 34a and 34b. The plunger 35 of the solenoid 33 has engagement holes 36a on the left and right,
The engagement member 37 formed with 36b is fixed. The link members 34a and 34b include an arm piece 39 having a cylindrical portion 38 formed at the lower end, and a horizontal piece 4 having a protruding pin 40.
A support rod 26, which is formed by integrally connecting 1 and 1 with a cylindrical body 42, and is fixed to the back surface of the mounting board 6,
Each cylindrical body 42 is loosely inserted into 26 and is rotatably supported. The spindles 22, 22 of the impellers 10a, 10b are loosely inserted into the cylindrical portions 38, 38 of the link members 34a, 34b, respectively, and are rotatably supported. Further, the pin 40 of the link member 34a is engaged with the engagement hole 36a of the engagement member 37, and the engagement hole 36a is engaged with the pin 40 of the link member 34a.

3, and thereby the impellers 10a and 10b are always urged to the inner position shown by the solid line in FIG. be placed in a state of

The rotation of the drive gear 30 by the drive of the forward/reverse rotation motor 28 is caused by the rotation of the impeller 10 via the small diameter gear 27a.
Rotation is applied to a, and the floating gear 31 and the small diameter gear 2
Through impeller 7b, impeller 10b is rotated at the same speed and in the opposite direction as impeller 10a. That is, the impellers 10a and 10b rotate outwardly in the first state and inwardly rotate in the second state. In this embodiment, the rotation direction of the forward/reverse rotation motor 28 is normally set so that the impellers 10a, 10b continue to rotate outwardly. Then, when the hit ball enters the special prize winning hole 14, the rotation of the forward/reverse rotation motor 28 is reversed. In addition, starting prize openings 4a and 4c provided on the game board 2
When a hit ball enters, the solenoid 33 of the impeller moving means 32 is energized once, and when a hit ball enters the starting prize opening 4b, the solenoid 33 is set to be energized twice.

As a ball receiving member, instead of the impellers 10a and 10b, for example, movable pieces are pivotally mounted opposite to each other on the front surface of the mounting board, and when both movable pieces are stopped in an upright position, the first state is such that it is difficult to receive a hit ball. In this case, both movable pieces may be tilted outward to create a second state in which the ball can be easily received. Alternatively, an opening/closing plate may be provided in front of a through hole formed in the mounting board, and the opening/closing plate may be opened forward in the first state, and opened in the second state. in this case,
A general prize winning hole and a special prize winning hole are formed at the back of the through hole.

Next, the operation of this embodiment will be explained. Impeller 10
When a and 10b are in the first state in which they are rotating outwardly from each other, a ball that falls onto the impellers 10a and 10b is only guided downward, making it difficult for the ball to enter the impellers. In this state, when a ball enters either of the starting prize openings 4a, 4c, the solenoid 33 is energized.
Therefore, the solenoid 33 sucks the plunger 35 downward, pulls down the horizontal pieces 41 of the link members 24a and 24b, and moves the arm pieces 39 outward against the force of the spring 43 as shown by diagonal lines in FIG. Rotate to. As a result, the impellers 10a and 10b move outward as shown by the chain lines in FIG. 5, expanding the receiving range of the hit ball. At the same time, the small diameter gears 27a and 27b of the impellers 10a and 10b are removed from the drive gear 30 and the floating gear 31, respectively, and the impellers 10a and 10b are free to rotate. Therefore, if the ball falls onto the impellers 10a and 10b at this time, the impeller 10
a, 10b rotates outward or inward depending on the position where the hit ball falls, and when it rotates inward, the hit ball is sent to the general winning holes 11a to 11c or the special prize winning hole 14.
lead to. The time during which the impellers 10a to 10b are moving outward is a predetermined time (e.g.
0.7 seconds), and when this predetermined time has elapsed, the solenoid 33 is demagnetized, and the link members 34a and 34b are rotated by the urging force of the spring 43, and the impeller 10 is rotated.
a and 10b return to their original positions as indicated by solid lines in FIG. 5, and at the same time, the small diameter gears 27a and 27b mesh with the drive gear 30 and the floating gear 31, respectively, and continue to rotate outward. Incidentally, when the hit ball enters the starting winning hole 4b, the above operation can be repeated twice. Incidentally, during the above operation, the solenoid 19 of the special prize winning opening 14 is demagnetized. For this reason, the sliding member 16 is retracted rearward as shown by the solid line in FIG. 7, and the winning hole 15 is located within the concave chamber 9, making it difficult for the ball to win.

When the balls hit by the impellers 10a and 10b enter the general winning holes 11a to 11c, they are simply won balls and are discharged. on the other hand,
When the ball enters the winning hole 15 of the special winning hole 14, the ball detection sensor 18 detects this, and based on the signal, the rotation of the forward/reverse rotation motor 28 is reversed to rotate inward, thereby causing the blade to rotate. The wheels 10a, 10b are rotated inwardly in the second state in which the ball is easily hit, and the solenoid 33 is energized at predetermined time intervals to move the impellers 10a, 10b outward for a predetermined period of time. A special prize game state continues (for example, for 30 seconds). During this operation, a plurality of balls (for example, 6 balls) are hit in the general prize opening 11a~
When the ball enters 11c, it is detected by the ball detection switch 46, and the solenoid 19 of the special prize winning opening 14 is energized. As a result, the plunger 20 is attracted and moves the sliding member 16 forward as shown by the chain line in FIG. Due to this movement of the sliding member 16, the winning hole 15 of the special prize winning hole 14 is positioned above the general winning hole 11b, making it very easy for the ball to enter. When the ball enters the winning hole 15, the solenoid 19 is demagnetized and the sliding member 16 retreats to its original position, at the same time the above operation is repeated again. In addition, this operation is repeated a certain number of times, and the ball hits the special prize winning hole 14 when a predetermined number of times (for example, 8 times) is completed, or within a predetermined time period during which the impellers 10a and 10b rotate inwardly. If not, the reversible motor 28 is reversely rotated to rotate outwardly, and the first impeller 10a, 10b rotates outwardly.
Return to state.

In this embodiment, the conditions for exciting the solenoid 19 of the special prize opening 14 are the general winning openings 11a to 11a.
Although the explanation has been made in relation to the number of balls hit into the winning hole 11c, the winning hole 15 may be moved to a position where balls can easily enter by energizing the winning hole 15 at regular intervals.
Alternatively, the winning hole 15 of the special prize winning opening 14 may be positioned in advance at a position where a hit ball can easily enter, and when a hit ball enters, the winning hole 15 may be moved to a position where it is difficult for a hit ball to enter.

[Effects of the Invention] As described above, according to the present invention, the special prize winning opening for giving the special prize game state is provided so as to be movable in the front and back direction,
By moving this special prize winning opening based on predetermined game conditions, it is possible to make it easier for the ball to enter, thereby attracting the interest of the players and improving the service to the players. This has the advantage of significantly increasing the interest of the game.
