Abstract

PURPOSE:To make variable the prize condition of ball to enhance the fun by a method wherein a guide frame is arranged to move freely up and down, and a gap between the circumference of a ratary body and the guide frame is made large when the guide frame is moved up to facilitate entering of prize balls in a waiting part. CONSTITUTION:Normally a guide frame 12 is at a down position and the gap between the circumferential face of a rotary body 11 and a guide frame 12 is small, and thus the driven ball is hard to enter a waiting part 25 while an opening and closing door 14 is in a closed state. When a right for a big prize is generated a solenoid in a prize generation device is excited to move the frame 12 against a spring member upwards. As a result, the gap between the circumference of the rotary body 11 and the guide frame 12 is made large, and thus conditions are changed to allow balls to enter the waiting part 25 easily. Simultaneously the door 14 is turned ahead with a pin as its fulcrum to open to facilitate the reception of balls. When the conditions are continued in a specified time energization of solenoid is interrupted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winning device for a pachinko machine, and more particularly to a winning device for a pachinko machine which uses a rotating body to win prize balls at predetermined time intervals.

[0002]

2. Description of the Related Art Conventionally, there has been known a winning device for a pachinko machine which uses a rotating body to win winning balls at predetermined time intervals. This winning device is, for example, as shown in FIG. 9, a rotating body 10 that is constantly rotated by a motor 100.
1 and an annular guide frame 1 surrounding the peripheral surface of the rotating body 101.
02, and a waiting portion 103 for waiting the winning ball on the peripheral surface of the rotating body 101 is provided in the upper center of the guide frame 102.

Then, when the ball holding portion 104 provided on the peripheral surface of the rotating body 101 coincides with the waiting portion 103 of the guide frame 102, the winning balls waiting in the waiting portion 103 are taken into the ball holding portion 104. I will carry it to the outlet 105.

On the other hand, this type of rotating body type winning device is arranged on the game board in association with, for example, a starting winning port, a variable display, a large winning port called an attacker, etc. as a specific winning device, and is used as a starting winning port. When the hit ball wins, the display state of the variable display starts to change, and if the stopped display result of the variable display is a hit, a big hit right is generated, and when the right hit occurs, the hit ball wins the specific winning device. Often used in so-called right-type pachinko machines, where the big hit is confirmed and the big winning opening is opened for each prize.

[0005]

By the way, in the pachinko machine of the above-mentioned right thing type, when the right of big hit occurs, the right of big hit is determined on condition that the special winning device wins, and the big winning opening Since the opening and closing cycle is updated, if you do not make it easy for the hitting ball to enter the specific winning device, even if the right to hit the big jackpot occurs, that right will be fixed or the opening and closing cycle of the special winning opening will be updated. In addition, the player uses a lot of hit balls, which makes the game uninteresting, which in turn makes the player dissatisfied with the possibility of leaving the customer.

On the other hand, in order to eliminate the above-mentioned inconvenience, for example, if it is made easy to hit a specific winning device with a hit ball at all times, the winning rate to the particular winning device becomes high, and the prize ball can be used even when the right is not generated. There was a problem that the amount of payout would be so large that the management of the pachinko amusement park could not be established.

The present invention has been made in view of the above problems of the prior art, and its object is to make it possible to change the winning state of a hit ball according to the content of the game. It is an object of the present invention to provide a winning device for a pachinko machine, which can make the game contents of the machine interesting and attract the player's interest.

[0008]

In order to achieve the above object, in the present invention, a rotating body which is constantly rotated by a motor is provided on the front surface of a mounting plate, and an annular guide frame which surrounds the peripheral surface of the rotating body. Provided on the peripheral surface of the rotating body is a sphere holding portion consisting of a recess for one sphere, and at the center of the upper part of the guide frame, a standby portion for waiting the winning ball on the peripheral surface of the rotating body is provided. In the winning device of the pachinko machine, in which the winning ball waiting in the waiting portion is taken into the holding portion and carried to the outlet when the ball holding portion coincides with the waiting portion, the guide frame can be moved up and down. And an electric drive source for moving the guide frame up and down on the back side of the mounting plate, and when the guide frame is moved upward, the gap between the peripheral surface of the rotating body and the guide frame is increased. It is designed to make it easy for winning balls to enter the standby part.

[0009]

When the guide frame that surrounds the peripheral surface of the rotating body is not moved upward, it is difficult for a hit ball to enter because the gap between the peripheral surface of the rotating body that serves as a standby portion and the guide frame is small. On the other hand, when the guide frame is moved upward by the operation of the drive source, the gap between the guide frames is increased and the ball can be easily hit. In this way, it is possible to change the winning state of the hit ball by vertically moving the guide frame surrounding the peripheral surface of the rotating body by the electric drive source.

Is provided. The variable display 51 is a well-known one having a 3-digit digital display unit, for example.

Next, the operation of the winning device 1 of this embodiment will be described. In the winning device 1 of this embodiment, the driving wheel 35 and the driven wheel 31 of the Geneva gear mechanism are driven by the motor 17.
The rotating body 11 is constantly rotating in the direction of the arrow in FIG. Further, in a normal state, since the solenoid 18 is not energized, the guide frame 12 is in the lowered position (solid line position in FIG. 7). Therefore, the rotating body 11
Since the gap between the peripheral surface of the guide frame 12 and the guide frame 12 is small, it is difficult for the hit ball to enter the standby portion 25. The open / close door 14 is in a closed state.

On the other hand, when the hit ball hit in the game section of the game board 49 passes through the normal chucker 52 and is detected by the winning ball detector 55, the digital of the variable display 51 is changed by the detection signal, When a certain time (for example, about 5 seconds) has passed, the fluctuation is stopped. Then, the display at the time of the stop is a preset display (for example, "1, 1, 1",
When "7, 7, 7" and the like are aligned, the opening / closing pieces 53a, 53a of the specific winning opening 54 are opened for a fixed time (for example, about 6 seconds) so as to be able to receive a hit ball.

In this state, the ball hits the V winning opening 56 at the same time when the opening / closing pieces 53a, 53a of the specific winning opening 54 are closed, and thus the right as a "big hit" is generated.
On the other hand, when the right is generated, the waiting unit 2 of the winning device 1

Contacts the engaging piece 32 of the guide frame 12 from below and moves the guide frame 12 upward against the bias of the spring member 47 (FIG. 6).
See the chain line). As a result, the peripheral surface of the rotating body 11 and the guide frame 1
The gap between the two becomes large, and the ball is converted into a state where the hitting ball easily enters the standby portion 25. At the same time, the pin 44 of the opening / closing door 14 is moved upward by the engagement groove 42 formed in the other engaging arm 43 of the operating member 39, whereby the opening / closing door 14 is moved.
Rotates about the pins 46, 46 as a fulcrum and opens so as to easily receive a hit ball.

The opening / closing door 14 is kept for a certain time (for example, 2
Until 7 seconds elapse, or a predetermined number (for example, 10 seconds)
When the individual hit balls are won and opened until they are detected by the prize ball detector 57, the solenoid 18 is de-energized and the solenoid 18 is demagnetized, whereby the guide frame 12 is biased by the spring member 47. Move down. Also, the open / close door 14
Is closed by the action of the return spring 48 of the plunger 37. In this way, when the right is generated, the guide frame 12 is moved upward so that the hit ball is likely to win the prize, provided that the hit ball wins the waiting portion 25 of the guide frame 12 and is detected by the prize ball detector. The conversion and the operation of opening the opening / closing door 14 are continued for a predetermined cycle (for example, 16 times).

[0025]

As described above, according to the present invention, the guide frame is moved upward so that the hit ball can easily enter the waiting portion each time the cycle is updated in the right generation state. Therefore, compared to the conventional device, the hitting ball can be more efficiently won in the standby portion, and many advantages can be given to the player.
