Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display control device for a game machine with an electrically variable display, and particularly to a display control device for a game machine equipped with an electrically variable display that can electrically change the display state. The present invention relates to a display control device for a gaming machine with an electrically variable display, which assigns a certain value based on the type of display information displayed on the machine.

In general, pinball gaming machines such as pachinko gaming machines and coin gaming machines that play games using pachinko balls have become widespread and are popular among players as a convenient form of leisure. Recently, in order to increase the interest of players, pinball game machines are equipped with electrically variable displays that can electrically change the display state. Examples of such an electrically variable display include a segment display and a display in which a plurality of light emitting diodes are arranged in a desired shape. A conventional pinball game machine equipped with an electrically variable display changes the display state of the electrically variable display based on a predetermined gaming state, and sequentially displays multiple types of display information. The variable display is stopped in response to a stop command, and a certain value (for example, prize balls or coins) is paid out based on the type of displayed information at that time. In addition, the electrically variable display is
Not only pinball game machines, but also slot machines and other game machines are used in place of conventional drums.

However, when making an electrically variable display variable display,
If the sequential variable display time is slow, the player will be more likely to match the type of display information that is determined to give a predetermined value.On the other hand, if the sequential variable display time is quick, the player will find it more interesting. You will lose money. therefore,
The variable display speed of the electrically variable display must be selected at an appropriate speed. However, the relationship between the variable speed of the electrically variable display and the probability of appearance of display information that can add a predetermined value is
It varies depending on the skill level of the player.

By the way, in a conventional pinball game machine equipped with an electrically variable display, it is not possible to change the probability of appearance of display information that can be assigned a predetermined value, so it is difficult to change the probability of appearance depending on the machine. However, in some gaming parlors, there is a desire to easily and quickly change the ball payout rate or coin payout rate without relying solely on conventional nail adjustments. Furthermore, for machines that have stopped playing, there may be cases where it is desired to change the ball payout rate, etc. even during business hours.

Therefore, an object of the present invention is to calculate the probability of a display state determined to provide a predetermined value in a gaming machine that is provided with an electrically variable display and provides a predetermined value depending on the display state. To provide a display control device for a game machine with an electrically variable display that can be changed with a simple operation.

In summary, the present invention provides a state in which the display state of the electrically variable display can be given a predetermined value by controlling the timing of generating and stopping the display control signal for controlling the display of the electrically variable display. This is to control the probability that becomes a preset probability.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a pachinko game machine (hereinafter referred to as pachinko machine) will be described as an example of a game machine equipped with an electrically variable display.

FIG. 1 is an external view of a pachinko machine according to an embodiment of the present invention. In the configuration, on the game board 1 of the pachinko machine 10 of this embodiment, there are a winning hole or a first winning ball device 2, and a Yakumono (commonly known as tulip) 3a, which is an example of a second winning ball device.

The winning ball device 2 is configured with openable and closable wing pieces that can be opened and closed on both the left and right sides, and a safe hole in which a pachinko ball can be won is formed in the upper part of the wing piece. The winning balls that have entered the winning ball device 2 are detected by a winning ball detection switch (22 shown in FIG. 2), which will be described later, and a variable display start command is issued to the segment display 21, which is an example of an electrical variable display, which will be described later. used to do. The conditions for instructing the segment display 21 to display a variable display are as follows: instead of or in conjunction with the winning balls entering the winning ball device 2, the ball passing areas 6a to 6C provided in the lower part of the game board 1 A passing ball appears. A segment display 21 is arranged in this display window. This segment display 21 is a numeric display in which a plurality of segments are formed in the shape of a Japanese character. It consists of a display device.

Note that the types of display information that can be displayed on the segment display 21 are numbers 0.1 to 9 if a numeric display is used.
It goes without saying that alphabets or other various identification symbols may also be used.

Other examples of electrically variable indicators include, for example, a plurality of light emitting diodes arranged in a circle and an identification symbol drawn at each position of each light emitting diode, or a cover with an identification symbol drawn on the front surface of the light emitting diodes. It may also be formed by It goes without saying that various other electrically variable indicators may also be used.

Further, below the front frame 11 of the pachinko machine 10, there are a prize ball dispensing port 12, a batted ball waiting gutter 13, a batting handle 14 for adjusting the batting strength, a prize ball tray 15, and a surplus prize ball dispensing port 16. provided. In addition, part of the front frame has
A stop command switch 17, which is an example of stop command means, is provided. As the stop command means, instead of the stop command switch 17 that generates a stop command signal by the player's operation as shown in the figure, a stop command switch 17 that generates a stop command signal after a certain period of time from the start of the variable display on the segment display is used. It may also be a timer.

FIG. 2 shows the block causes of the display control device 20 according to an embodiment of the present invention. In the configuration, the display control device 20 of this embodiment includes a winning ball detection switch 22, which is an example of a start command means for instructing to start variable display on the segment display 21, and a winning ball detection switch 22, which is an example of a start command means for instructing the segment display 21 to start variable display. A display control means 23 for sequentially and variably displaying , a stop command switch 17 which is an example of a stop command means, and a signal for giving a predetermined value with a preset probability according to the output of the stop command switch 17 is generated. Probability control means 24
, and a predetermined device assigning circuit 25 that assigns a predetermined value based on a predetermined value assigning state.

FIG. 3 is a time chart for explaining the operation of FIG. 2, and particularly shows the output pulse P1 of the pulse oscillator 23H and the output pulse P2 of the variable pitch oscillator 24a.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 to 3. A player plays a ball hitting game by putting pachinko balls borrowed from a ball rental machine into the ball waiting gutter 13 and adjusting the hitting strength by rotating the ball hitting handle 14. In response to this, a ball hitting motor (not shown) is driven to rotate, and a ball hitting rod (not shown) is intermittently rotated to drive pachinko balls into the game board 1 one after another. At this time, the hit ball is the winning ball device 2
Or Yakumono 3a to 3e or safe hole 4a.

4b, a predetermined number of prize balls are paid out for each winning ball in the same manner as in conventional pachinko machines.

Incidentally, the segment display 21 normally continuously displays the number when the variable display was stopped last time. When the hit ball enters the winning ball device 2, the winning ball is detected by the winning ball detection switch 22. The output (high level) of the winning ball detection switch 22 is output by the display control means 2.
The flip-flop 23b included in No. 3 is set.

The set output q of the flip-flop 23b is given to the pulse oscillator 23a as an activation signal, and the ANI
) is applied to gate 24d, disabling the AND gate 24d. The pulse oscillator 23a generates pulses P1 at regular intervals in response to the activation signal. The period of the output pulse P1 of this pulse oscillator 23a is
A period (for example, 0.1 seconds) is selected so that the player can understand that the sequential display of 1 is changing. This pulse P1 has a constant period (0, 1 second) and a constant pulse width. Output pulse P of pulse oscillator 23a
1 is given to the decimal counter 23C. The decimal counter 23C increments its count value by 1 each time the pulse P1 is input, sequentially counts the numerical values from 0 to 9, and resets the count value every time it counts 10. do. That is, the decimal counter 23C functions as a ring counter that sequentially counts the numerical values 0 to 9. This decimal counter 23C includes output terminals corresponding to count values O to 9, and derives a 71-level signal from the output terminal corresponding to the count.

By the way, the display information or display state of the segment display 21 that is determined to give a predetermined value is determined to be when the number 7 is displayed, for example. In this case, 1
The output terminal of the count value 0 to 6 of the 0-base counter 23C is AND
It is given as one input of gates 230 to 236, and the output terminal with a count value of 8.9 is given as one input of AND gates 238 and 239. Each AND gate 230-23
For each other input of 6°238 and 239,
The output of inverter 23d is given. At this time, if the flip-flop 23b is set, the output of the latch circuit 24e is at a low level. This low level signal is inverted to high level by an inverter 23d and applied to AND gates 230-236°238.239. Therefore, each AND gate 230-236, 238, 2
39 derives a high level signal and supplies it to the decoder 23e when a high level is applied from the output terminal corresponding to the count value of the decimal counter 23C. Therefore, the decoder 23e decodes the count value of the decimal counter 23C and provides its output to the driver 23'f. driver 2
3f. drives the segment display 21 to display based on the output of the decoder 23e. As a result, after receiving the winning ball detection output, the segment display 21 changes the numbers 0 to 6, 8.9 as the count value 23C increments sequentially from 0 to 6, 8.9. indicate. Here, the reason why the number 7 is not driven to be displayed on the segment display 21 is because the signal for commanding the display of the number 7 is sent from the latch circuit 24e to the decoder 23e.
15 because they are not given.

As described above, when the segment display 21 is sequentially and variably displayed in synchronization with the period of the output pulse of the pulse oscillator 23a, the player can select the display state (number 7) determined to give a predetermined value. Operate the stop command switch 17 so that the display state is as follows. Now, assuming that the stop command switch 17 is operated, the flip-flop 23b is reset in response to the operation of the stop command switch 17. Therefore, the set output q becomes low level.

In response to this, the pulse oscillator 23a stops its oscillation operation. At the same time, the inverter 24b inverts the low level to the high level and provides the high level signal as one input of the AND gate 24d, and also outputs the high level signal to the AND gate 24d.
Give a latch command signal to 4C1. This AND game) 2
-4d is given the output pulse of the variable pitch oscillator 24a as the other input.

The variable pitch oscillator 24a changes the pulse generation period α by adjusting the variable resistor 24C.

For example, one pulse width of the output pulse P2 of the variable pitch oscillator 24a is changed to the output pulse p1 of the pulse oscillator 23b.
By selecting the same period as the period α and varying the period α, it is possible to change the probability that the number 7 is hidden. For example, the period α is set to a time corresponding to the pulse width of pulse P2 (for example, 0
．． 1 second), the number 7 is segment display 2.
The probability of being displayed as 1 can be set to 1. Also, if the period α is chosen to be twice the time corresponding to the pulse width of pulse P2, then
You can set the probability that the number 7 will be displayed. Similarly, by adjusting the variable resistor 24C in order to vary the period α, the probability that the number 7, which is determined to give a predetermined value, is displayed can be varied.

The latch circuit 24e outputs the latch command signal at the timing when the inverter 24b becomes high level and derives the latch command signal.
At that time, the output state derived from the AND gate 24d (
High level or low level) is read and stored. Therefore, when the flip-flop 23b is reset in response to the operation of the stop command switch 17 at the timing when the AND game 24d is deriving a low level, the latch circuit 24e reads and stores the low level signal. At this time, since the signal stored and held in the latch circuit 24e is at a low level, the decoder 23e does not derive a decode output for displaying the number 7. Therefore, in this case, the segment display 21
will continue to display the previous number.

On the other hand, when the stop command switch 17 is pressed at the high level timing of the output pulse P2 of the usable pitch oscillator 24a, the AND gate 24d derives a high level signal. At this time, the latch circuit 24e
At the timing when the output of 4b becomes high level,
The output state (ie, high level signal) of the AND gate 24d is read and stored.・This latch circuit 24e
The high level signal stored in the decoder 23 is used as a signal to display the number 7 to which a predetermined value should be assigned.
given to e. Therefore, the decoder 23e provides a decoded output of the number 7 to the driver 23f. In response, the driver 23f causes the segment display 21 to display the number 7.

Further, the output of the decoder 23e is given as a comparison input to a comparison circuit 25a included in the value adding circuit 25.

The comparison circuit 25a is given a set value of the number (7) set by the setter 25b to which a predetermined value should be assigned as a reference input. Also, flip-flop 23
The reset output Q of b is given to the monostable multi 25C. Accordingly, the monostable multi 25C switches the stop command switch 1
Deriving a high level signal for a certain period of time from the press of 7,
It is given to the comparison circuit 25a as a comparison command signal.

Therefore, when the comparison command signal is given, the comparison circuit 25a compares the output of the decoder 23e and the reference signal from the setting device 25b, and if they match, derives a matching output and outputs the matching output to the Yakumono drive circuit. Give to 25d. Accordingly, the Yakumono drive circuit 25d drives the Yakumono 3a to 3e.
Among them, a renoid provided in connection with a yakumono that is predetermined to open according to a predetermined display state is electrically energized to control opening of the yakumono. As a result, when the display state of the segment display 21 becomes a display state determined to give a predetermined value, a predetermined number of Yakumono are controlled to be released as an example of the predetermined value.

For this reason, the winning probability of the hit ball becomes high, and the player can easily win the prize ball.

As mentioned above, according to this embodiment, variable resistor 24C
By adjusting the resistance value of the segment display 2 to vary the period α of the output pulse of the variable pitch oscillator 24a,
1 has the advantage of being able to freely adjust the probability of displaying display information determined to give a predetermined value. In addition, by simply adjusting the resistance value of the variable resistor 24C, the probability of giving a predetermined value can be changed, so as a result, it is possible to adjust the number of prize balls to be paid out. This has the advantage that the ball output rate of the pachinko machine can be changed without adjusting the nails that have been set.

By the way, in the embodiment shown in FIG.
We have described the case where the variable pitch oscillator 24a is used to vary the period α in order to adjust the probability that the display state is determined to give a predetermined value. This can also be achieved by various embodiments.

FIG. 4 is a block diagram of a display control device 30 according to another embodiment of the present invention. In this embodiment, 33 is used in place of the display control circuit 23 in FIG. 2, and 34 is used in place of the probability control means 24. The rest of the configuration (value adding circuit 25) is the same as that in FIG. 2, and will therefore be omitted.

FIG. 5 is a time chart for explaining the operation of the embodiment shown in FIG.

Next, with reference to FIGS. 4 and 5, the specific configuration and operation of FIG. 4 will be described.

If the condition is not such that the segment display 21 can be readably displayed, the flip-flop 33b included in the probability control means 33 remains reset. Therefore, the data selector 33d selects the counter 34b. This counter 34b increments its count value by 1 every time a pulse output from the pulse oscillator 34a is applied, and cyclically counts from 0 to 9. The output pulse of the pulse oscillator 134a is selected to be lower than the oscillation frequency of the pulse oscillator 33a. Therefore, before the hit ball enters the prize ball device 2, the data selector 33d gives the count value of the counter 34b to the driver 33e, and the segment display 2
Display it on 1. That is, the segment display 21 sequentially and periodically displays 0 to 9 at a relatively slow speed synchronized with the oscillation frequency of the pulse oscillator 34a. At this time, the flip-flop 3 is included in the monostable multi 34d.
Since the set output Q (low level) of 3b is input, it remains disabled. Therefore, even if the counter 34b counts the number 7, it does not operate. That is,
The display time of the number 7 becomes equal to the display time of the other numbers.

On the other hand, when the hit ball enters the winning ball device 2, the winning ball detection switch 22 detects it and flips the flip-flop 33b.
to be set. Accordingly, the data selector 33d
selects the count value of the counter 33C1 and sends it to the driver 33e.
give to The counter 33C increments its count value every time an output pulse from the pulse oscillator 33a is given, and the counter 33C increments its count value to 0.
-9 is repeated and counted. At this time, since the oscillation frequency of the pulse oscillator 33a is selected to be considerably higher than the oscillation frequency of the pulse oscillator 34a, the step speed of the counter 33C becomes faster.

Therefore, the numbers 0 to 9 are sequentially and periodically displayed on the segment display 21 at a speed synchronized with the oscillation frequency of the pulse oscillator 33H. At this time, set output force Q
is applied to the monostable multi 34d as an activation signal.

Therefore, the monostable multi 34d sets its output level to high level according to the signal input when the decoder 34C detects the count value 7 of the counter 34b, and the output level is determined by the time constant of the variable resistor 34g, the resistor 34f, and the capacitor 34e. 1. The output is inverted with a delay of g time T1. The counting operation of the counter 34b is prohibited during a signal output period of a certain period (T1) of the monostable multi-channel 34d. Then, when the counting operation prohibition signal of the monostable multi 34d disappears, the counter 34b increments the count value again every time there is an input pulse. However, the counter 34b increments the count value to 8 when the next pulse input is applied after the output of the monostable multi 34d disappears. In this way, after a winning ball is detected, the time for the counter 34b to count the number 7 changes depending on the counting operation prohibition signal period of the monostable multi 34d.

At this time, the counting operation prohibition command signal of the monostable multi 34d can be freely varied by adjusting the resistance value of the variable resistor 34g. Then, the player presses the stop command switch 1.
When 7 is pressed, the flip-flop 33b is reset by the pressing signal, and the count value of the counter 34b is selected by the data selector 33d and given to the driver 33e. Therefore, the segment display 21 displays a number based on the count value held by the counter 34'b. At the same time, the monostable multi 34d is disabled.

In this way, when a stop command is issued, the counter 34b
holds the count value at that time, but the counter 34b
A value (
For example, the probability of the value 7) is determined by the ratio of the period during which the counting operation prohibition signal is given from the monostable multi 34d to the cycle period of the count value of the counter 34b. The probability can be freely changed only by adjusting the resistance value of .

The operation of stopping the display state of the segment display 21 and then assigning a predetermined value based on the display state is similar to the operation shown in FIG. 2. For that purpose, the output of the data selector 33d is applied to the comparison circuit 25a, and the reset output Q of the flip-flop 33b is applied to the monostable multi 25C. Value adding circuit 2 in this case
5 is the same as that shown in FIG. 2, so its explanation will be omitted.

In each of the above-mentioned embodiments, customs was made for a pachinko machine as an example of a gaming machine, but the technical idea of the present invention is not limited to pachinko machines, but also applies to coin gaming machines, slot machines using electrically variable displays, etc. It can also be applied to

As described above, according to the present invention, in a game machine equipped with an electrically variable display, it is possible to freely and easily change the probability of a display state determined to impart a predetermined value. . When a game machine to which this invention is applied is installed in a game parlor, the probability of giving a predetermined value can be changed even when the game parlor is open, and it is possible to change the probability of giving a predetermined value more than a predetermined number of times. It can be prevented.
