Description

Description: TECHNICAL FIELD The present invention relates to a ball striking device for a pachinko machine that shoots a ball by driving an electric drive source.

[Prior Art] Conventionally, a hitting ball launching device for a pachinko machine is configured to reciprocally rotate a hitting ball by an electric drive source such as a drive motor or a rotary solenoid to shoot a hitting ball. And the number of shots is always constant (100 / minute)
The electric drive source was driven so that Also, a small number of proposals have been proposed in which the number of shots of the hit ball can be changed by the selection of the player. However, even if it is possible to change the number of shots, the number of shots is controlled only by the selected number of shots, so that the game is eventually played with a fixed number of shots.

[Problems to be Solved by the Invention] By the way, in a pachinko game on a pachinko machine, there is a case where it is desired to change the number of shots of a hit ball according to the game state. For example, in a slump state of a pachinko game, in a state where the payout rate is low (state in which the probability of winning in the winning hole is low), it is desirable to reduce the number of shots of the hit ball to reduce the reduction rate of the possessed ball. In the state where the ball output is high, there is an expectation that the number of shots will be increased to obtain a large number of prize balls, and when the pachinko game becomes a special game state where there is a chance to acquire a large number of prize balls. , There is a desire to make the number of shots as high as possible.
In this way, it is desired to change the number of shots corresponding to various game states, but in the above-described hitting ball launching device, since the number of shots is constant, it is not possible to satisfy the above request, Even if the number of shots can be changed, there is a problem that the player has to select the number of shots corresponding to the gaming state each time.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a hitting ball launching device of a pachinko machine capable of automatically changing the number of hits of a ball hitting in response to a game state. It is in.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a hitting ball launching device of a pachinko machine according to the present invention launches a hitting ball by driving an electric drive source. It is provided with a payout rate calculating means for calculating a payout rate per hour, and a special game state detecting means for detecting that a pachinko game is in a predetermined special game state, and the hitting ball launching device is in a normal game state. In, a first firing rate control means for controlling an electric drive source so as to change the firing rate of the hit ball in proportion to the ball yield rate calculated by the ball yield rate calculation means, and the special game state detection means The second firing number control means for controlling the electric drive source so that the number of shots of the hit ball is maximized on the basis of the detection output of.

[Operation] In a normal game state, a hit ball is shot based on the number of shots calculated by the payout rate calculating means. For this reason, when the gaming state is in a state where the payout rate is poor, the number of shots is automatically selected to be low, and when the gaming rate is good, the number of shots is automatically set to be high. To be selected. That is, in the normal gaming state, the number of shots is controlled so as to always change based on the payout rate.

On the other hand, when the pachinko game enters the special game state where it is a chance to win a large number of prize balls, the firing operation is performed so that the number of shots of the ball is maximized. Therefore, the probability of winning a prize ball is improved, and the enjoyment of the game can be obtained.

A collection path 18 for collecting at a place and collecting to a not-shown lifting device is provided. A distribution pipe 17 is hung down on the distribution path 16 so as to correspond to each pachinko machine 1, and a prize ball flowing down the distribution path 16 is guided to the storage tank 13. On the other hand, a discharge ball tank 19 is provided at a position corresponding to the discharge port 14 above the recovery path 18 so as to correspond to each pachinko machine 1. The discharge ball tank 19 temporarily receives the discharge balls discharged from each pachinko machine 1 and then drops them into the recovery path 18. The discharge ball tank 19 has a discharge port inside as shown in FIG. 14
It includes a safe sphere detector 20 for detecting only safe spheres among the discharge spheres discharged from the sphere, and a discharge sphere detector 21 for detecting all discharge spheres. The safe sphere detector 20 is of a type in which the detection signal is derived by passage of the generated safe sphere, and the discharge sphere detector 21 has a predetermined position (for example,
This is a form in which one detection output is derived each time 10 (10) discharge balls pass. Then, the detection signals from the safe ball detector 20 and the ejector detector 21 are input to the microcomputer 27, which will be described later, and serve as a basis for calculating the ball output rate per predetermined time. For example, counting the signals of the safe sphere detector 20 and the discharge sphere detector 21 for a predetermined number of minutes,
Based on the count value, the payout rate (the number of safe balls / the number of discharged balls) in the predetermined several minutes is calculated. Then, based on the calculated ball output rate, in this embodiment, the rotational speed of the drive motor 26 of the hitting ball launching device 25 is controlled to change. Specifically, the number of shots shot is, for example, 70 to 10
It can be changed between 0 / minute, but the lower the ball output rate is, the lower the number of shots is automatically selected, and the higher the ball is, the maximum number of shots is selected. do it. For example, if the payout rate is "0.03 or less", 70 /
80 minutes / minute when the payout rate is "0.04 to 0.06" and 90 when the payout rate is "0.07 to 0.08".
If you select the number per minute and the payout rate is "0.09 or more", 10
It may be configured to select 0 pieces / minute.

In addition, in order to calculate the payout rate, in this embodiment, it is performed based on the safe ball and the discharge ball.
Alternatively, the calculation may be performed based on the number of prize balls supplied from the storage tank 13 to the storage tank 13 and the discharge balls.

Next, the hitting ball launching device 25, which is the main part of this embodiment, will be described. As shown in FIG. 3, the hitting ball launching device 25 has a driving motor 26 as an electric driving source, and a rotary cam (not shown) fixed to the output shaft of the driving motor 26 and a hitting rod (not shown). ) And is intermittently engaged and disengaged so that the ball can be fired by reciprocally rotating the ball. Therefore, the number of shots can be controlled by controlling the rotation speed of the drive motor 26. In order to control this rotation speed, the microcomputer 27 and the microcomputer 27 are provided near the drive motor 26. There is provided a frequency converter 28 for changing the rotation speed of the drive motor 26 in response to a command from the.

As shown in the block diagram of FIG. 4, the microcomputer 27 includes a safe sphere input circuit including the safe sphere detector 20.

The microcomputer 27 may be configured to receive an input signal from the operation button circuit 35. As shown in FIG. 7, the operation button circuit 35 sends a signal to the microcomputer 27 based on the operation of the firing number conversion operation button 29 provided on the upper portion of the operation handle 8, and operates a switching button (not shown). It is used when playing a game after manually changing the number of shots. In other words, in this embodiment, the number of shots can be automatically controlled, and the number of shots can be manually changed by the player's intention to continuously play a game at a fixed number of shots. It can also be configured to be able to.

The control operation of the above-described micro computer 27 will be described. A safe sphere input circuit 30 and an out sphere input circuit 31.
Based on the input signal from the microcomputer 27
Calculates the payout rate. This calculation is performed every predetermined unit time (for example, 1 to 3 minutes). Then, the frequency converter drive circuit is changed from the microcomputer 27 so that the number of shots is predetermined based on the calculated ball output rate.
An output signal is sent to the frequency converter 28 via 34, and the rotation speed of the drive motor 26 of the pachinko machine 1 is automatically controlled based on the output signal. For example, when the ball output rate is low, as shown in FIG. 5, the number of shot balls is small, so the number of balls discharged from the discharge port 14 of the mechanism plate 12 to the discharge ball tank 19 is small, On the other hand, if the ball output rate is high, as shown in FIG.
The number of discharge balls falling from the discharge ball tank 19 into the discharge ball tank 19 increases.
In this way, when the ball output rate is low, it is possible to reduce the number of ball hits and reduce the reduction rate of balls that are held, and conversely, when the ball output rate is high, increase the number of ball hits. As a result, it is possible to increase the possibility that a large number of prize balls will be obtained, and it is possible to obtain amusement of the game.

Controlling the number of shots based on the input signals from the safe sphere input circuit 30 and the out sphere input circuit 31 is in the normal game state, and when this is the big hit state which is the special game state. That is, when there is an input signal from the operation input circuit 32 at the time of winning a pachinko machine, the control of the number of shots based on the above-mentioned ball output rate is stopped, and the maximum number of shots, that is, 100 / The output signal is sent from the microcomputer 27 to the frequency converter 28 via the frequency converter drive circuit 34 to increase the number of rotations of the drive motor 26. Therefore, since the number of shots per unit time increases in the special game state, the number of prize balls to the center accessory 10 provided on the game board 6 increases and the interest in the game is improved. You can

The configuration and operation of the hitting ball launching device 25 of the pachinko machine 1 according to the embodiment have been described above, but in the above embodiment,
