Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winning rate control method for a pachinko machine, and particularly to a winning rate control method for a pachinko machine that automatically controls the winning rate in a pachinko machine.

Generally, a pachinko machine is equipped with at least a plurality of obstacle nails, a prize ball chutka, an out hole, and a guide on the game board, and a game ball fired onto the game board by a player enters the prize ball chutka. If the game ball is safe, a plurality of balls are brought to the player, which is a profit, and if the game ball goes into the out hole, it is a loss for the player.

Therefore, the winning rate is given by , and how to set this winning rate K is an extremely important issue for the management of pachinko parlors.

This winning rate depends on the spacing of the pachinko machine's obstructing nails, the tilt of the pachinko machine itself, etc., but how to set these usually requires special skills and money, is extremely difficult, and involves a lot of work. It requires human resources.

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks by making it possible to automatically control the winning rate, and will be described in detail below using examples.

FIG. 1 is a block diagram of a winning rate control method for a pachinko machine according to the present invention. In the figure, 1 is a calculation unit, and the ratio K of the number of winning balls and the number of outs based on the number of safes inputted as an electric signal. This K is compared with the setting value of 2 of the upper setting device 2 and the setting value of 3 of the lower setting device 3.

That is, the electrical signal for the number of outs, which is a loss for the player, is compared with the electrical signal for the number of safes, which is a profit, and the value of the ratio is compared with a set value.

Then, when the winning rate K exceeds the setting value of the upper setting device by 2, a close signal S2 is generated to cause the winning rate control device 4 (described later) to perform an operation to reduce the winning rate K, and the winning rate Make K approach the setting value of lower setting device 3 to 3.

When the winning rate K exceeds the set value of the lower setting device 3 by 3, an open signal S1 is generated to cause the winning rate controller 4 to perform an operation to increase the winning rate K.

Figure 2 is a characteristic diagram showing how the winning rate changes based on such operations.As is clear from the figure, the larger the range between 2 and 3 in the set value, the more dynamic the winning rate changes. This allows you to enjoy dynamic games, and if this width is small, you can play games with less fluctuation.

FIG. 3 shows another embodiment of the winning rate control device for a pachinko machine according to the present invention, and the same parts as in FIG. 1 are denoted by the same reference numerals.

Reference numeral 5 denotes a storage section, which functions to give a computation instruction to the computation section 1 to perform a computation operation when the number of game balls fired reaches a predetermined number n.

6 is a desired setting device. According to such a configuration, when the number of shots reaches a certain number n, the calculation unit 1 calculates the winning rate K.
is calculated, and this winning rate K is set to 4 in the desired setting device 6.
When the winning rate K is larger than 4, a close signal S2 is sent to the winning rate controller 4, and when the winning rate K is smaller than the set value of the desired setting device 6, an open signal S1 is sent to the winning rate controller 4.

This controls the winning rate K.

FIG. 4 is a characteristic diagram showing how the winning rate changes based on such an operation.

As is clear from the figure, by reducing the number n stored in the storage unit 5, the winning rate K can be brought closer to the desired set value.

FIG. 5 shows another embodiment of the winning rate control method for a pachinko machine according to the present invention, and the same parts as in FIG. 3 are designated by the same reference numerals.

Reference numeral 7 denotes a repeat computation indicator according to an arbitrary set time, which sends a signal to the storage unit 5 at every set time to cause the computation unit 1 to perform a computation operation at this time t.

According to such a method, the calculation unit 1 can be operated at fixed set time intervals, and when the winning rate K calculated by the calculation is larger than the desired set value of 5, the closing signal S2 is sent out. When it is small, an open signal S1 is sent out, and the winning rate K can be controlled within a certain range.

Figure 6 is a characteristic diagram showing how the winning rate changes based on such an operation, and as is clear from the figure, if the set time t is shortened, the winning rate K can be brought closer to the desired set value of 5. I can do it.
