Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pachinko gaming machine that is provided with a variable display device on a gaming board surface for playing, for example, a throttle game or a roulette game.

[Technical background of the invention and its problems]

A pachinko game machine has a plurality of winning holes on a game board surface, and when a pachinko ball hit by a player along the board hits the winning hole, a certain number of prize balls are paid out. For this reason, if the winning rate is too low, the interest of players will be lost, and conversely, if the winning rate is too high, the gaming parlor will become unprofitable. j7 Therefore, the gauge adjustment that must be done every day to keep the winning rate at an appropriate value is I! i-tech store?
1. This is important work. Therefore, at pachinko parlors, after the shop closes, the gauges of each pachinko machine are adjusted based on the operating status of each machine on that day.

By the way, in recent years, pachinko gaming machines with so-called electric accessories have become popular. In a pachinko game machine equipped with an electric accessory, when a pachinko ball enters a special prize hole, a throttle game is played, for example, and a three-digit number is displayed. When the display becomes a specific display mode (for example, when the game ends at 7, 7, 7 and 8), the opening/closing door of the central blur will remain open for a certain period of time, and the specific display will Even if this is not the case, the opening/closing door will be in the open state, albeit for a very short time. For this reason,
Once a pachinko ball enters the special prize hole, the winning rate increases rapidly thereafter. The frequency of occurrence of this specific display mode is approximately proportional to the number of winning balls that enter the special winning hole, so in order to make the small balls of the pachinko machine have an appropriate value, it is necessary to adjust the number of winning balls that enter the special winning hole. be.

However, conventional gauge adjustment relies on information calculated by a total winning hole detector that detects pachinko balls that have entered all winning holes and a 1-ball detector that detects balls that are out. Therefore, it was not possible to clearly determine whether or not the number of prizes entered into the special prize hole should be adjusted.

For this reason, in conventional pachinko gaming machines, the gauge adjustment relied on the intuition of the administrator, making it difficult to adjust the pachinko machine to have appropriate small balls and balls.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and allows accurate gauge adjustment by confirming at least one of the number of operations of the variable display device or the number of winnings in the special winning hole using a simple device. The purpose is to provide a pachinko game machine that can

b and 6c are special winning holes provided with winning ball sensors 8 (not shown), and when a pachinko ball wins there, the numerical display devices 4a, 4b, and 4C convert and display random numbers.

A pachinko ball can be won in the V winning hole 5a provided inside the center pocket 5 only when the opening/closing door 5b is opened by a solenoid SOL (not shown). Further, on the game board surface 3, a V lamp 9 indicating that the opening/closing door 5b is in an open state and a windmill 10 for regulating winnings to the winning holes 6a to 6f are arranged. In addition, 11 is a stop switch that stops the conversion display of the numerical display devices 4a, 4b, and 4c, 12 is an instruction switch that instructs to display the integrated value of the number of pachinko balls that have entered the special winning hole, and 13 is a control switch that indicates the strength of the batted ball. 13a is a ball-striking switch for emitting a pachinko ball firing signal, and 14 is a speaker.

A player operates a ball hitting handle 13 and a ball hitting switch 13a to hit a pachinko ball. Then, the launched pachinko balls flow into the game board surface 3 along the guide rail 2 and fall along the game board surface 3. The fallen pachinko balls will either enter one of the winning holes or be collected in the out hole 7. In the process, the one with the pachinko ball is the special prize hole 6a.
・Go to either 6b or 6c. Then, a detection signal is emitted from the winning ball sensor 8, the number of winning balls is stored, and the numerical display devices 4a, 4b, and 4c start converting and displaying. After a certain period of time has elapsed, or when the player presses the stop switch 11, the conversion display stops and the numerical display 4a, 4b
・4c displays a 3-digit number. If this three-digit number displays, for example, 7, 7, 7, the lamp 9 lights up, the speaker 14 emits a sound effect, and the opening/closing door 5b of the central pocket 5 remains open for 30 seconds. Also,
Even when other numbers are displayed, the opening/closing door 5b remains open for 0.5 seconds and the winning rate is significantly improved.

When adjusting pachinko machines after the game parlor is closed,
Memorized number of operations of numerical display 4a, 4b, 4C,
Or, at least one of the accumulated values of the number of pachinko balls that have entered the special winning holes 6a, 6b, and 6C is displayed on the numerical display 4a.
4b, 40, etc., so accurate gauge adjustment can be performed based on this.

Furthermore, the number of operations of the numerical display 4a, 4b, 4c is appropriate, too many, too few, or the special winning hole 6
Different color lamps, etc. are used to indicate which machines have a proper winning rate for a, 6b, and 6c, which machines have a winning rate that is too high, and which machines have a winning rate that is too low, so you can quickly and accurately adjust the gauge. .

In addition, since the number of operations of the numerical displays 4a, 4b, and 4c and the number of pachinko balls that have entered the special winning holes 6a, 6b, and 6c are approximately the same, in order to simplify the explanation below, in this embodiment, the special winning holes are This article describes the case where the gauge is adjusted based on the number of wins in 6a, 6b, and 6C.

FIG. 2 is a block diagram when a microcomputer is used as the control device for the pachinko game machine according to this embodiment, in which 51 is a CPU, 52 is a ROM in which a program is written, and 53 is used as a work area. RAM
It is. The detection signal etc. of the entered prize ball sensor 8 are sent to the data bus DB through the input buffer 54. Also, C
Numerical display 4 is output from PU51 via output latch 55.
Control data is given to a, 4b, 4c, etc. A driver 56 drives the numerical display devices 4a, 4b, 40, etc. based on the control data.

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 section is operated by a specific ball detection signal from the winning ball sensor 8, and generates a control signal for converting and displaying irregular numbers from 0 to 9 on the numerical displays 4a, 4b, and 4C. a timer 62 that outputs a signal after a certain period of time after receiving a specific ball detection signal, and an operation of the random generator 61 when receiving the output signal of the timer 62 or the signal from the stop switch 11. OR gate G, which issues a signal to stop the
A selection circuit 63 that selects information from the random generator 61 when there is no 1 indicating signal from the 7chi 12, a decoder 64 that decodes the information selected by the selection circuit 63, and numerical displays 4a, 4b, It consists of a dry harrow 5 that drives 4C.

Further, the number display drive section includes a counter 71 that integrates the specific ball detection signal from the winning ball detection sensor 8, a selection circuit 63 that selects information on the counter 71 based on an instruction signal from the I indication switch 12, and the selection circuit. A decoder 64 that decodes the information selected by 63, and numerical display devices 4a, 4b, and 4C.
A driver 65 drives the comparator 72 and the comparator 72 converts information from the counter 71 in response to an instruction signal from the instruction switch 12.
Game 1-G2 sent to 73. :! :, an upper limit comparator 72 that lights up a red lamp RL via a driver 75 when the integrated value of the counter/tough 1 is larger than a preset upper limit setting value of the upper limit setter 740; A lower limit comparator 73 that lights up a yellow lamp YL via a driver 77 when the integrated value is smaller than a lower limit set value of a lower limit setter 76 set in advance, and a counter 71 thereof.
AND gate G2 which lights up the blue lamp BL via the driver when the integrated value is smaller than the preset upper limit setting value of the upper limit setting device 74 and larger than the lower limit setting value of the lower limit setting device 76; Consists of.

In addition, 81 receives information from the variable display drive unit and sets the numerical display devices 4a, 4b, and 4c to a specific display mode (for example,
7.7.7), a signal is applied to the drivers 83, 84 and the AND gate G4 via the timer 82, and the solenoid is driven to open/close the opening/closing 653 of the central pocket 5. This is a judgment circuit that lights up the sound effect circuit 85 and 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 explained. First, the pachinko balls are in special winning holes 6a, 6b, and 6.
When C is won, the winning ball sensor 8 sends its detection signal to the random generator 61. The random generator 61 thereby sends irregular numerical information from 0 to 9 to the driver 65 via the selection circuit 63 and decoder 64. driver 65
continuously converts and displays the three-digit display of the numerical display devices 4a, 4b, and 4C, which are composed of seven segments in the shape of a "day", into irregular numbers from 0 to 9. Numerical display 4a/4
When the player presses the stop switch 11, a stop signal is sent to the random generator 61 and the conversion display of b.4C is stopped. Further, even if the stop switch 11 is not pressed, after a certain period of time has elapsed, a stop signal from the timer 62 is sent to the random generator 61 to stop the operation.

Note that the three-digit numerical value when the conversion display of the numerical display devices 4a, 4b, and 4C is stopped is determined by the discrimination circuit 81, and when it becomes a specific display mode (for example, 7, 7, 7), Dry for a certain period of time 83 via timer 82
The opening/closing door 5 of the central pocket 5 is driven by the solenoid.
A is opened for 30 seconds. Further, even when a specific display mode is not adopted, the opening/closing i5a is kept open for 0.5 seconds. If a pachinko ball enters the winning hole 5a while the opening/closing 1i5a is in the open state, the opening time is further updated for 30 seconds. During this time, if the pachinko ball enters a pocket 5 other than the winning hole 5a, the numerical display devices 4a, 4b, and 4C will start displaying the conversion again, and if the display after the conversion display becomes 7, 7, 7, As Yuko repeats the above-mentioned actions, the pachinko balls temporarily enter the special winning holes 6a and 6b.
・If you win 6c, your winning rate will improve significantly from then on.

Further, the detection signal from the entered prize ball sensor 8 is sent to the counter 7.
1, and the counter 71 accumulates and stores this detection signal, that is, the number of pachinko balls that have won in the special winning holes 6a, 6b, and 6C.

Next, press the instruction switch 12 to adjust the gauge 311 of the Pananco gaming machine after closing. Then, in response to the instruction signal, the selection circuit 63 selects the numerical display 4a, 4b,
4C from the random generator 61 to the counter 71
Switch to the information. Then, the information stored in the counter 61 that accumulates and stores the number of balls that entered the special prize hole while the store is open is displayed as a three-digit number on the numerical displays 4a, 4b, and 4C via the decoder 64 and driver 65. Ru. Therefore, the winning rate in the special winning hole can be adjusted based on this number, so it is possible to easily adjust the small balls of the pachinko game machine to an appropriate value.

In addition, in this embodiment, the number of balls that have entered the special winning hole is not only displayed numerically, but also the integrated value of the counter 71 is compared by an upper limit comparator 72, and is compared with the upper limit setting value set in advance by an upper limit setting device 74. When it is also large, 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 a lower limit comparator 73, and when it is smaller than the lower limit setting value set in advance by a lower limit setter 76, a signal is sent to a driver 77 to turn on a yellow lamp RL. Furthermore, when the integrated value of the counter 71 is smaller than the upper limit set value preset by the upper limit setter 74 and larger than the lower limit set value set by the lower limit setter 76, the AND gate Gy sends a signal to the driver 78. Send it and 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 gauge is adjusted so that the winning rate to the special winning hole is high. All you need to do is adjust the gauge; if the blue lamp is lit, there is no need to adjust the gauge. As a result, it is possible to very easily determine whether or not the stand requires gauge adjustment, and gauge adjustment can be performed quickly and reliably.

The functions of the control device of this embodiment have been explained above.
The actual operation is performed according to a program stored in the ROM of the microcomputer.

FIG. 4 is a flowchart showing the contents of the program.

First, the CPU 51 clears the register area of the RAM 53 (step ■). Next, the CPU 51 uses the counter 71
Read whether there is a request to display the integrated value of (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, return to step (■), and repeat steps (2) and (2) below.

If there is a detection signal, the counter 71 is counted up (step (2)), and the numerical displays 4a, 4b, 4c are driven to convert and display the numerical values (step (2)). Steps below ~
Repeat step (2) to add up the number of pachinko balls that hit the special prize holes.

On the other hand, if there is a display request, the CPU 51 displays the numerical value display 4.
The information sent to a, 4b, and 4C is switched from the random generator 61 to the information of the counter 71 (step 2). Then, the number of winnings of pachinko balls stored in the counter 71 in the special winning holes is displayed on the numerical display devices 4a, 4b, and 4C (
Step ■). Furthermore, the integrated value of the counter 71 is the same as the upper limit set value previously set by the upper limit setter 74 and the upper limit comparator 7.

Further, when the integrated value of the counter 71 is smaller than the upper limit setting value, the integrated value of the counter 71 is compared with the lower limit setting value set in advance by the lower limit setter 76 by the lower limit comparator 73 (step (Illill). If the value is smaller than the lower limit set value, turn on the yellow lamp (step ■
)finish.

Further, when the integrated value of the counter 7I is smaller than the upper limit setting value and larger than the lower limit setting value, the blue lamp is turned on (step @) and the process ends.

According to the first embodiment, since the existing numerical value display is commonly used as the number display device, it is possible to provide an inexpensive pachinko gaming machine.

In addition, in the above embodiment, the case where the number of wins in the special winning hole is detected and the gauge is adjusted is described, but the number of winnings in the special winning hole and the number of operations of the numerical display may be activated by winning in Pocket 5, so there is not necessarily a 1:l correspondence. Therefore, the gauge may be adjusted by detecting the number of times the numerical display is operated, or the gauge may be adjusted based on information obtained by detecting both numbers. In the latter case, the gauge can be adjusted taking into consideration the winning in the pocket 5, so that the small ball can be adjusted more accurately.

Further, in the above embodiment, a numerical value display device of a pachinko game machine is used as the number display device, but separately from this, a dedicated numerical value display device may be provided on the back side of the pachinko game machine, for example.

Further, as the number display device, a display device of a control device that remotely and centrally manages a plurality of pachinko gaming machines may be used. This allows you to see the number of operations on the numerical display devices of multiple pachinko machines at once, making it easy to adjust the settings and changes of so-called service machines and collection machines from the perspective of the entire pachinko parlor. .

Furthermore, the number of times display device may be displayed using audio information written in advance in a 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 embodiment, the instruction switch is provided on the front of the pachinko game machine, but in order to prevent mischief by the customer service, it may be provided inside the pachinko game machine, for example, on or near the game board surface.

In addition, in the embodiment described in L, a unique switch is provided as the instruction switch, but this instruction switch may also share an existing stop switch.For example, the stop switch is normally pressed together with the batting switch. Yes, and it is pressed for a short period of time. Therefore, the pressing time is determined by a microcomputer, and when the stop switch is pressed alone for more than a certain period of time, it is used as an instruction switch, and when it is used together with the batting switch or for less than a certain period of time, it is used as a stop switch. be able to. According to this embodiment, there is no need to open or close the front door of the pachinko game machine in order to press the instruction switch, and adjustment work can be performed quickly.

Also, a timer may be used as an instruction switch, for example, to issue a signal at 11 p.m. after closing.
If the ball hitting switch is not turned on for a predetermined period of time or more, an instruction signal may be automatically sent.

In the latter case, the ``ζ'' signal may be sent when the game parlor is open, so in order to prevent the players from knowing the displayed contents, the 3-digit number sequence should be placed on the right side. From there, processing is performed such as setting the number to 100, 10, 1, etc. According to this embodiment, by using a timer, it is possible not only to provide an inexpensive pachinko game machine, but also to
No operation is required to press the instruction switch, and adjustment work can be performed quickly.

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

Furthermore, in the above embodiment, a numerical display for playing a throttle game was used as the variable display device, but other types of variable display devices are also possible, and the player's profits can vary significantly depending on the gaming state. If so, it doesn't matter what it is.

(Effects of the Invention) As explained above, according to the present invention, at least one of the number of operations of the variable display device or the number of entries into the special winning hole is 11.
Since this can be confirmed with a simple device, accurate gauge adjustment can be performed based on this data, and a pachinko game machine can be provided that can provide fair services to players.
