Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention can be connected to an electric drive source on a game board surface and can be converted into a closed state in which a hit ball is not accepted and an open state in which a hit ball is easily accepted. When the movable wing piece and the variable winning device having a general winning opening and a special winning opening for winning the hit ball received in the open state of the movable wing piece and the starting winning opening are arranged on the game board surface, and the hitting ball enters the starting winning opening The electric wing is activated to open the movable wing piece in a state where it is regulated by time and the number of times, and when the ball hits the special winning opening in the opened state, the movable wing piece is opened in a unique manner by the control device. The present invention relates to a pachinko machine that generates a so-called special game state that is converted into a state.

[Prior Art] As a conventional pachinko machine of the above type, for example, Japanese Patent Laid-Open No.
The one described in JP-A-58-112571 is known.

In this conventional pachinko machine, when a hit ball wins the first starting opening, the electric drive source of the variable winning device is operated for 0.7 seconds,
The movable blade is converted from the closed state to the open state only once.
When the ball hits the second starting port, the movable wing piece is converted into the open state twice for 0.7 seconds each. And if the ball hits the special winning opening when the movable wing piece is in the open state,
Move the movable winglet continuously for the time described above, that is, 0.7 seconds
Repeatedly opens and closes, and repeats the above 18 consecutive times as 1
It is set as a cycle, and a so-called special game state which is advantageous for a player and which can update the cycle up to eight times is generated.

[Problems to be Solved by the Invention] By the way, in this type of pachinko machine, if the number of occurrences of the special game state is large, the rate of the one-day ball becomes too high and the management of the amusement shop becomes unsuccessful. The adjustment of the number of occurrences of the special gaming state has a great influence on the management of the game store, such that the popularity decreases and the number of gamers decreases when the number of occurrences is small. On the other hand, the condition for generating the special game state is that the hit ball received by the movable wing piece of the variable winning device is returned to the closed state from the opening to the special winning opening. Therefore, whether or not the special game state is generated has an important role in the opening time when the ball hits the starting winning opening and the movable wing piece is opened.

However, in the conventional pachinko machine, since the opening time of the movable wing piece of the variable winning device that is opened when the hit ball wins the starting winning opening is set to a certain time by the control device, the number of occurrences of the special game state is In order to make adjustments, we have no choice but to rely on daily nail adjustments, and we are spending a lot of labor and time.

Therefore, an object of the present invention is to provide a pachinko machine capable of adjusting the number of occurrences of a special game state without requiring troublesome nail adjustment.

[Means for Solving the Problems] According to the present invention, a movable wing piece is axially attached to the front surface of a substrate, and an electric drive source is connected to the movable wing piece so that a hit ball is not accepted and a hit ball is easily accepted. It can be converted into the open state and the movable wing piece has a variable winning device having a general winning opening and a special winning opening for winning the hit ball received in the opened state, and a starting winning opening is arranged on the game board surface, When the start winning hole is won, the electric drive source is activated to open the movable wing piece in a state regulated by time and number of times. At the same time, in the pachinko machine that generates a special game state where the control device converts the movable wing piece to the open state in a unique manner when the hit ball wins the special winning opening in the open state, the hit ball wins the starting winning opening. It is configured to include an opening time changing means for changing the opening time of the movable wing piece of the variable winning device which is opened at that time.

[Operation] The opening time changing means makes it possible to change the opening time of the movable wing piece of the variable winning device which is opened when the hit ball wins the starting winning opening. Therefore, if the opening time of the movable wing piece is shortened, the number of hit balls that can be accepted by the movable wing book will be reduced, and the probability of winning at the special winning opening will be low. Although the number of hit balls accepted by the wing pieces increases and the probability of winning in the special winning opening increases, it is possible to easily adjust the number of occurrences of the special game state without requiring troublesome nail adjustment.

FIG. 5 shows a flow chart for explaining the control operation of this embodiment, and then the operation of this embodiment will be explained with reference to FIG. First, a normal case will be described in which a hit ball enters the first starting winning opening 5, 5 and the movable wing pieces 8, 8 of the variable winning device 4 are opened for 0.44 seconds. That is,
When the power is turned on, CPU20 initializes and sets the timer to 0.4
Set to 4 seconds (step S2). Next, the CPU 20 determines whether or not any of the timer switches T1, T2, T3 is turned on (steps S3, S4, S5). When it is determined that they are all off, the process proceeds to step S6 and the first start is performed. It is determined whether or not a hit ball has been won in the winning openings 5 and 5, and until the prize is won, step S3
~ Repeat S6. And the first start winning hole of step S6
When it is determined that the hit ball is won in 5, 5, the process proceeds to step S7, the timer is started to give a signal to the solenoid drive circuit 22 to excite the solenoid 13, and the process proceeds to step S8.
As a result, the movable wings 8, 8 of the variable winning device 4 are opened. Then, in step S8, it is determined whether or not the timer counts 0.44 seconds, and when the timer counts 0.44 seconds, the CPU2
0 gives a stop signal to the solenoid drive circuit 22 to stop the excitation of the solenoid 13 (step S9). As a result, the movable wing pieces 8, 8 of the variable winning device 4 are closed, and the control operation returns to the beginning (step S3).

The explanation of the control operation described so far is about the case where the movable wing pieces 8, 8 of the variable winning device 4 are opened for 0.44 seconds,
Next, a case where the opening time of the movable blades 8, 8 is changed to 0.4 seconds will be described.

That is, when changing the opening time of the movable blades 8, 8 to 0.4 seconds, the timer switch T1 is turned on. When it is determined in step S3 that the timer switch T1 is turned on, the timer is reset to 0.4 seconds in step S10 and the process proceeds to step S6. Then, in step S6, the first starting winning opening 5,
When it is determined that the hit ball is won in 5, the timer is started in step S7, a signal is given to the solenoid drive circuit 22 to excite the solenoid 13, and the process proceeds to step S8. As a result, the movable wings 8, 8 of the variable winning device 4 are opened. Then, in step S8, it is determined whether or not the timer counts 0.4 seconds, and when the timer counts 0.4 seconds, the CPU 20 gives a stop signal to the solenoid drive circuit 22 to stop the excitation of the solenoid 13 (step S9 ). As a result, the movable wing pieces 8, 8 of the variable winning device 4 are closed, and the control operation returns to the beginning (step S3).

Further, when changing the opening time of the movable blades 8, 8 to 0.5 seconds, the timer switch T3 is turned ON. When it is determined in step S5 that the timer switch T3 is turned on, the timer is reset to 0.5 seconds in step S11 and the process proceeds to step S6. When it is determined in step S6 that a hit ball has been won in the first start winning opening 5,5, a timer is started in step S7 to give a signal to the solenoid drive circuit 22 to excite the solenoid 13 and then to step S8. move on. As a result, the movable wings 8, 8 of the variable winning device 4 are opened. Then, in step S8, it is determined whether or not the timer counts 0.5 seconds, and when the timer counts 0.5 seconds, the CPU 20 gives a stop signal to the solenoid drive circuit 22 to stop the excitation of the solenoid 13 (step S9 ). As a result, the movable wing pieces 8, 8 of the variable winning device 4 are closed, and the control operation returns to the beginning (step S3).

Further, when the opening time of the movable blades 8, 8 is changed from 0.4 seconds or 0.5 seconds to 0.44 seconds with the power turned on, the timer switch T2 is turned on. When it is determined in step S4 that the timer switch T2 is turned on, the timer is reset to 0.44 seconds in step S12 and the process proceeds to step S6. When it is determined in step S6 that a hit ball has been won at the start winning openings 5, 5, the process proceeds to step S7, and the control operation is performed thereafter in the same manner as the 0.44 second opening described above.

In addition, according to the present invention, when a hit ball is won in the first starting winning port 5,5, the opening time of the movable wing pieces 8,8 of the variable winning device 4 is controlled by operating a timer switch provided in each pachinko machine. Although it has been described as changeable, the opening time of the movable wing pieces 8, 8 can be similarly changed with a simple circuit configuration when, for example, a hit ball wins the second starting winning opening 6 or is in a special winning state. .

Also, instead of setting the winning probability with a timer switch,
An external terminal may be provided for remote control by a hall management computer or the like. In addition, RO is a table showing the relationship between the time of day, day of the week, weather and winning probability.
The final value determined by the timer may be read from the table in accordance with the elapsed time of the day by the calendar timer output, the day of the week or the weather data manually input, which is stored in M21. If so, it is possible to automatically control the winning probability with respect to time, day of the week, or weather.

[Effects of the Invention] As described above, according to the present invention, a movable wing that is connected to an electric drive source on the game board surface and can be converted into a closed state in which a hit ball is not accepted and an open state in which a hit ball is easily accepted. A variable winning device having a general winning opening and a special winning opening for winning the hit ball received in the open state of the movable piece and the movable wing piece, and a starting winning opening are arranged on the game board surface, and when the hitting ball enters the starting winning opening, it is electrically operated. The drive source is operated to open the movable winglets in a state regulated by time and number of times, and when the hit ball enters the special winning opening in the opened state, the device converts the movable winglets to the opened state in a unique manner.
