Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a pachinko gaming machine in which a variable display device for playing, for example, a throttle game or a roulette game is provided on a game board surface.

[Technical background of the invention and its problems]

The pachinko gaming machine has a plurality of prize holes on the surface of the game board, and when a pachinko ball hit by the player along the board wins the prize hole, a certain number of prize balls are refunded. Therefore, if the winning rate is too low, the interest of the player will be lost, and conversely, if the winning rate is too high, the profitability of the gaming shop becomes unprofitable. Therefore, adjusting the gauges every day in order to make the winning rate an appropriate value is an important task for the game store. Therefore, after closing the pachinko gaming machine, the gauge of each pachinko gaming machine is adjusted based on the operating state of each pachinko gaming machine on the day.

By the way, in recent years, so-called pachinko game machines with electric accessories have become popular. In a pachinko gaming machine with an electric accessory, when a pachinko ball wins a special winning hole, for example, a throttle game is played and a three-digit number is displayed. When the display becomes a specific display mode (for example, when the game ends with 7/7/7), the opening / closing door of the central pocket remains open for a certain time, and even if the display mode does not become the specific display mode, it is extremely short. Although it is time, the door will be open. Therefore, once the pachinko ball wins the special winning hole, the winning rate sharply improves thereafter. Since the frequency of occurrence of this particular display mode is approximately proportional to the number of balls that have won in the special winning hole, it is necessary to adjust the number of winnings in the special winning hole in order to obtain an appropriate value for the balls of the pachinko gaming machine. is there.

However, the conventional gauge adjustment is based on the information calculated by the total winning hole detector that detects the pachinko balls that have won all the winning holes provided for each pachinko gaming machine, and the out ball detector that detects the out balls. Since it was done, it was not possible to clearly determine whether or not to adjust the number of winnings to the special winning hole.

For this reason, in the conventional pachinko game machine, since the gauge adjustment is performed depending on the intuition of the administrator, it is difficult to adjust the pachinko machine for proper ball entry and entry.

FIG. 2 is a block diagram when a microcomputer is used as a control device for the pachinko gaming machine of this embodiment, 51 is a CPU and 52 is a program written RO
M and 53 are RAMs used as work areas. The detection signal of the winning ball sensor 8 is sent to the data bus DB through the input buffer 54. Further, control data is given from the CPU 51 to the numerical indicators 4a, 4b, 4c and the like via the output latch 55. 56 is a numerical display 4a based on the control data
-It is a driver that drives 4b, 4c, etc.

FIG. 3 is a block diagram illustrating the functions configured according to the program contents written in the ROM of the microcomputer used as the control device in this embodiment.

First, the variable display drive unit operates by the specific sphere detection signal from the winning sphere sensor 8 to cause the numerical indicators 4a, 4b, 4c to display 0-9.
Random generator 61 that generates a control signal for converting and displaying irregular numbers up to, a timer 62 that outputs a signal after a fixed time after receiving a specific sphere detection signal, and an output signal or stop of the timer 62 The OR gate G ₁ that issues a signal to stop the operation of the random generator 61 when receiving the signal from the switch 11 and the information from the random generator 61 when there is no instruction signal from the instruction switch 12 is selected. Selection circuit 63, decoder 64 for decoding the information selected by the selection circuit 63, and driver for driving the numerical displays 4a, 4b, 4c
It consists of 65 and.

Further, the number-of-times display drive unit includes a counter 71 that integrates the specific ball detection signals from the winning ball detection sensor 8, a selection circuit 63 that selects information of the counter 71 according to an instruction signal from the instruction switch 12, and the selection circuit 63. Decoder 64 that decodes the selected information and driver 65 that drives the numerical displays 4a, 4b, 4c
Similarly, the gate G ₂ which sends the information of the counter 71 to the comparators 72 and 73 by the instruction signal from the instruction switch 12, and the integrated value of the counter 71 is larger than the preset upper limit value of the upper limit setter 74. Sometimes, when the upper limit comparator 72 that lights the red lamp RL via the driver 75 and the lower limit set value of the lower limit setter 76 set in advance by the integrated value of the counter 71 are smaller than the lower limit set value by the driver 77 When the integrated value of the lower limit comparator 73 that lights the lamp YL and the counter 71 is smaller than the upper limit set value of the preset upper limit setter 74 and larger than the lower limit set value of the lower limit setter 76, the driver
The AND gate G ₃ lights the blue lamp BL via 78.

In addition, 81 receives the information from the variable display drive unit, and the numerical indicators 4a, 4b, and 4c display in a specific display mode (for example, 7/7.
7), a signal is applied to the drivers 84 and 84 and the AND gate G ₄ via the timer 82 to drive the solenoid to open the opening / closing door 5a of the central pocket 5 and turn on the V lamp 9. At the same time, it is a determination circuit that sends a signal from the sound effect generation circuit 85 to the speaker 14 via the driver 86 to generate a sound effect.

Next, the operation of the control device configured as described above will be described. First, when the pachinko ball wins the special winning holes 6a, 6b, 6c, the winning ball sensor 8 sends the detection signal to the random generator 61. As a result, the random generator 61 sends irregular numerical information of 0 to 9 to the driver 65 via the selection circuit 63 and the decoder 64. Driver 65 is 7 in the shape of "day"
Numerical display 4a, 4b, 4c composed of segments 3
The digit display is continuously converted and displayed as an irregular number from 0 to 9. The conversion display of the numerical displays 4a, 4b, 4c is such that when the player presses the stop switch 11, the stop signal is a random generator.
It is sent to 61 and stops. Further, even if the stop switch 11 is not pressed, a stop signal is sent from the timer 62 to the random generator 61 after a certain period of time, and then the random generator 61 is stopped.

It should be noted that the 3-digit numerical value when the conversion display of the numerical indicators 4a, 4b, 4c is stopped is judged by the judging circuit 81, and when it becomes a specific display mode (for example, 7/7/7), The solenoid is driven by the driver 83 for a certain period of time via the timer 82 to open the open / close door 5a of the central pocket 5 for 30 seconds. Further, even when the specific display mode is not displayed, the open / close door 5a is kept open for 0.5 seconds. Door 5
While a is in the open state, the pachinko ball has a V winning hole 5
If you win a, the opening time will be updated for another 30 seconds. If the pachinko ball wins the pocket 5 other than the V winning hole 5a in the meantime, the numerical indicators 4a, 4b, 4c start the conversion display again, and if the display after the conversion display is 7.7.7, The above operation is repeated thereafter.

Therefore, once the pachinko ball wins the special winning holes 6a, 6b, 6c, the winning rate is significantly improved thereafter.

The detection signal from the winning ball sensor 8 is a counter 71.
The counter 71 accumulates and stores this detection signal, that is, the number of pachinko balls that have won the special winning holes 6a, 6b, 6c.

Next, after closing the store, when adjusting the gauge of the pachinko gaming machine, the instruction switch 12 is pressed. Then, in response to the instruction signal, the selection circuit 63 switches the information sent to the numerical indicators 4a, 4b, 4c from the random generator 61 to the information of the counter 71.
The information of the counter 61, which is stored by accumulating the number of balls won in the special winning hole during the opening of the store, is the decoder 64, the driver.
It is displayed on the numerical indicators 4a, 4b, 4c as a 3-digit number via 65. Therefore, the winning rate to the special winning hole can be adjusted based on this number, so that the exit of the pachinko gaming machine can be easily adjusted to an appropriate value.

Further, in the present embodiment, not only the number of balls won in the special winning hole is displayed as a number, the integrated value of the counter 71 is compared by the upper limit comparator 72, and the upper limit set value preset by the upper limit setter 74 is set. When is also larger, a signal is sent to the driver 75 to turn on the red lamp RL. On the other hand, the integrated value of the counter is compared by the lower limit comparator 73, and when it is smaller than the lower limit set value preset by the lower limit setter 76, the driver
Send a signal to 77 to turn on the yellow lamp RL. Further, when the integrated value of the counter 71 is smaller than the upper limit set value set by the upper limit setter 74 in advance and is larger than the lower limit set value set by the lower limit setter 75, the AND gate G ₃
Sends a signal to the driver 78 to turn on the blue lamp.

Therefore, if the red lamp RL is lit, the gauge is adjusted so that the winning rate to the special winning hole is low, and if the yellow lamp RL is lit, the winning rate to the special winning hole is high. You only need to adjust the gauge, and if the blue lamp is on, you don't need to adjust the gauge. As a result, it is possible to very easily determine whether or not the table requires gauge adjustment, and the gauge adjustment can be performed quickly and reliably.

The function of the control device according to the present embodiment has been described above.
The actual operation is performed according to the program stored in the ROM of the microcomputer. FIG. 4 is a flow chart showing the contents of the program.

First, the CPU 51 clears the register area of the RAM 53 (step). Next, the CPU 51 reads the presence / absence of a display request for the integrated value of the counter 71 (step). If there is no display request, the detection signal from the winning ball sensor 8 is read (step). If there is no detection signal, the process returns to step, and the following steps are repeated. If there is a detection signal,
The counter 71 is counted up (step), and the numerical indicators 4a, 4b, 4c are driven to convert and display the numerical values (step). The following steps are repeated to accumulate the number of prizes in the special prize hole of the pachinko ball.

On the other hand, if there is a display request, the CPU 51 causes the numerical display units 4a and 4b to
The information sent to 4c is switched from the random generator 61 to the information of the counter 71 (step). Then, the number of winnings of the pachinko ball stored in the counter 71 into the special winning hole is displayed on the numerical indicators 4a, 4b, 4c (step). further,
The integrated value of the counter 71 is compared with the upper limit set value preset by the upper limit setter 74 and the upper limit comparator 72 (step). When the integrated value is larger than the upper limit set value, the red lamp is turned on and the step is finished.

When the integrated value of the counter 71 is smaller than the upper limit set value, the integrated value of the counter 71 is compared with the lower limit set value preset by the lower limit setter 76 and the lower limit comparator 73 (step). When the integrated value is smaller than the lower limit set value, the yellow lamp is turned on (step) and the process ends.

Further, when the integrated value of the counter 71 is smaller than the upper limit set value and larger than the lower limit set value, the blue lamp is turned on (step) and the process ends.

According to the first embodiment described above, since the existing numerical value display device is shared as the number-of-times display device, it is possible to provide an inexpensive pachinko gaming machine.

In the above-mentioned embodiment, the case where the number of winnings in the special winning hole is detected and the gauge is adjusted has been described, but the number of winnings in the special winning hole and the number of times of operation of the numerical display are the numerical display. May operate by winning in the pocket 5, so there is not necessarily a 1: 1 correspondence. Therefore, the gauge may be adjusted by detecting the number of operations of the numerical display, or the gauge may be adjusted based on the information obtained by detecting both numbers. In the latter case, the gauge can be adjusted in consideration of the winning in the pocket 5, so that more accurate ball exit adjustment can be performed.

Further, in the above embodiment, the numerical display device of the pachinko gaming machine is used as the number-of-times display device, but apart from this, for example, a dedicated numerical display device may be provided on the back surface of the pachinko gaming machine.

Further, a display device of a control device that remotely and centrally manages a plurality of pachinko gaming machines may be used as the number-of-times display device. With this, the number of times the numerical display devices of a plurality of pachinko gaming machines are operated can be viewed at one time, and so-called service table and collection table settings and changes can be easily adjusted from the standpoint of the entire gaming shop.

Further, the number of times display device may be displayed using voice information written in advance in the memory chip, or may be used in combination with the number of times display device described above. By using them together, more accurate gauge adjustment can be performed.

Further, in the above-described embodiment, the instruction switch is provided on the front surface of the pachinko gaming machine, but it may be provided inside the pachinko gaming machine, for example, on or near the gaming board surface in order to prevent a player from playing a trick.

Further, although the original switch is provided as the instruction switch in the above embodiment, the instruction switch may share the existing stop switch. For example, the normal stop switch is pushed together with the ball hitting switch, and is pushed for a short time. Therefore, it is possible to judge the pressing time with a microcomputer and use it as an instruction switch when the stop switch is pressed independently for a certain time or more, and as a stop switch when used together with a ball hitting switch or when the time is less than a certain time. it can. According to this embodiment, the operation of opening and closing the front door of the pachinko gaming machine is not required because the instruction switch is pressed, and the adjustment work can be performed quickly.

Also, a timer may be used as an instruction switch, and for example, a signal may be output at 11 pm after the store is closed, or an instruction signal may be automatically sent when the ball hitting switch is not turned on for a predetermined time or more. May be. In the latter case, a signal may be sent even during the opening of the game shop, so in order to keep the displayed contents unknown to the player, the sequence of three-digit numbers is arranged from the right side. 100
Take measures such as moving to the 1s, 10s, and 1s positions. According to the present embodiment, by using the timer, not only an inexpensive pachinko game machine can be provided, but also an operation for pressing the instruction switch becomes unnecessary, and the adjustment work can be performed quickly.

Further, in addition to the above-mentioned instruction switches, when a plurality of pachinko gaming machines are remotely controlled centrally, the operation switch of the remote control device may be shared. This saves the trouble of operating the switch for each pachinko gaming machine when adjusting the gauge.

Further, in the above-mentioned embodiment, the variable display device is a numerical display device for playing a throttle game, but other variable display devices may significantly change the profit of the player depending on the gaming state. If so, it doesn't matter what.

〔The invention's effect〕
