Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pachinko game machine, particularly one equipped with an electric winning device called a yakubutsu.

[Prior Art] In the field of pachinko gaming machines, machines equipped with electric winning devices called so-called yakumono are used to improve services for players and expand the number of customers who can enjoy the games. being developed.

This variable winning device temporarily establishes a winning area with a high winning probability within the gaming area when a specific situation occurs due to chance. With such accessories, everyone is given the opportunity to receive a large amount of prize money, and this makes it possible to provide fair services.

However, if the profits brought to players by the variable prize winning device become excessive, there is a fear that it will actually encourage gambling.

Therefore, in this type of pachinko game machine with accessories, a count detector detects winning balls in the variable winning device, and the number of winning balls in the winning area is set below a certain level based on the detection output of this count detector. (usually 10 or less), thereby limiting the profits brought to the player to an appropriate range.

The count detector is called a so-called 10 count detector, and detects all the winning balls that have won in the variable winning device. This detection output is used to turn on/off the switch (O
It is output in the state of N/○FF). Based on the detection output of this count detector, the number of winning balls entering the variable winning device is counted. Then, the count value is a certain limit number (
When the number of winnings (usually 10) is reached, further winnings are restricted by, for example, stopping the operation of the variable winning device.

However, if the count detector loses its function due to, for example, a disconnection or short circuit of its wiring,
Along with this, the function of the above entry prize restriction means is also lost. For this reason, in this type of pachinko gaming machine, there is a concern that the machine may be used illegally by intentionally disabling the function of its count detector.

Therefore, in order to prevent unauthorized use of this type of pachinko gaming machine, attempts have been made to provide a count detector failure detection means for logically determining whether or not the function of the count detector is normal. Providing such a means certainly makes it difficult for unauthorized use to occur through simple techniques such as cutting or shorting the wiring.

[Problems to be Solved by the Invention]However, even if a count detector failure detection means for logically determining whether the function of the count detector is normal or not is provided, the count detection cannot be detected using a rather complicated method. There is a risk that the function of the incapacity detection means itself may be removed.

[Object of the Invention] The present invention is intended to solve the above-mentioned problems, and its typical purpose is to significantly prevent the unauthorized disabling of the function of the count detector failure detection means. The object of the present invention is to make it more difficult to prevent unauthorized use of a pachinko game machine equipped with a variable prize winning device.

The above-mentioned and other objects and novel features of the present invention will become clear from the description of Book N and the accompanying drawings.

Note that in FIG. 1, the same reference numerals indicate the same or corresponding parts.

2 to 9 show the main body side portion of a pachinko game machine to which the present invention is applied.

First, the outline and operation of the pachinko game machine according to the present invention will be briefly explained with reference to FIGS. 2 and 3.

FIG. 2 shows an example of the overall configuration of a pachinko game machine according to the present invention, and FIG. 3 shows a gaming area 1 formed on the game board l.
An example of the configuration of a is shown below.

In FIGS. 2 and 3, a ball hitting guide rail 3 is provided on the front surface of the game board l. This ball guide rail 3
guides the game ball, that is, the batted ball, fired by the batted ball firing device i12 to the upper part of the game area 1a. Ball launcher! 2 is operated and driven by a lower operation dial knob 2a.

The game area 1a includes the ball guide rail 3 and the opening/closing panel 1.
It is formed in a space surrounded by the glass plate 01. In this gaming area 1a, various winning holes 5a, 6b, 6c*798.53a and winning devices 5, 9 forming a winning area are arranged. Along with this, a large number of obstacle nails 11 and various guiding members 12a, 12b, 12c
, direction setting members 13a, 13b, etc. are provided.

These allow the ball hit into the game area la to fall while changing its direction in various ways.

At the lowest part of the game area 1a, an out port 10 is provided for collecting the hit balls that did not win in any of the winning areas to the back of the game board.

Further, in the center of the game area 1a, a variable display device 4, which serves as a type of game device, is installed.

This variable display bag! 4 is a segment type display using one light emitting diode LEDA, LEDB, LEDC, LEDD
Arabic numerals from 0 to 9 are displayed. When the variable display device 4 operates, the displayed numbers on each of the indicators LEDA to LEDD change respectively. This change is stopped when the player operates the stop switch SW2 or when a certain amount of time has elapsed. At this time, if the combination of displayed numbers after this stop results in a pre-contracted result, a specific mode described later will be generated.

The above-mentioned winning holes 6ae, 6h, 6c, 7, 8t 53a are fixed winning holes whose winning areas are always open. These prize openings 6a, 6b+ 6c, 7t 8t53a are
Depending on its function, the general prize opening 6a.

e b t 6 c g 53 a and specific winning lower,
It is classified into 8. The batted ball wins the general prize RO 6a, 6b, 6
c.

53a, a predetermined number (usually 10 to 15) of prize balls will be paid out. When the batted ball enters the special winning lower, 8, in addition to being paid out a predetermined number of prize balls as in the case of winning in the general winning hole, the variable display device 4 is activated as will be described later. Opportunities for special benefits will be provided.

The above winning device i! 5.9, a tulip type winning device 9 and a special variable winning device 5 are provided.

Among them, the special variable winning device 5 does not normally have a winning area, but it has a variable display! ! A specific aspect occurs as a result of the stoppage of the variable display operation in step 4.
A wide special variable prize opening 80 with a very high winning probability is temporarily opened. Furthermore, inside the special variable prize opening 80,
It is divided into a normal winning hole 82 which only brings a predetermined number of prize balls, and a continuous winning hole 81 which gives the right to reopen the special variable winning hole 80 in addition to the prize balls.

On the other hand, an illuminated central display member 20 is disposed above the game board l. This illuminated concentrated display member 20 includes:
A prize lamp 21 that is temporarily turned on when a batted ball enters one of the winning areas; a turbo lamp 22 that is turned on or blinks when a specific condition occurs due to the stoppage of the variable display operation of the variable display device 4, which will be described later. “Jackpot”
Special variable prize winning device 5 when the specific aspect occurs
A segment type indicator LED numerically displays the number of times the open state continues, and the number of times it continues is set to a predetermined limit number (10
A completion lamp 24 is provided to notify the completion of the game by the special variable prize winning device 5 when the game reaches the maximum number of times.

Further, the variable display device 4 is provided with lighting means 27 for jackpot display. This lighting means 27 includes the segment type indicators LEDA, LEDB, LEDC, LED
While the display by D is changing, it is lit for one blink. Furthermore, when a specific aspect of a "big win" occurs, the blinking speed is controlled to become faster. As a result, the operation of the variable display device i4 and the occurrence of a "jackpot" are effectively produced and displayed.

Furthermore, a continuation condition fulfillment display section 29 is provided within the special variable prize winning device 5. This continuation condition fulfillment display section 2
9 is when a specific form of “jackpot” occurs,
When a ball hits the continuous winning hole 81, the lighting is driven. As a result, it is displayed that a special continuation right to re-open the special fluctuating prize opening 80 has been granted.

A firing device drive lamp 26 is provided on the upper part of the holding frame 100 of the pachinko game machine that holds the game board 1 having the above configuration. This firing device drive lamp 26 is turned on when the operation dial knob 2a of the batted ball firing device is operated.

In addition, an opening/closing panel 101 attached to the holding frame 100
A supply tray 102 is attached to hold the batted balls to be supplied to the batted ball launcher. Furthermore, below.

Receiving tray 1 for storing prize balls overflowing from the supply tray 102
03 is provided.

” on the side (left side in the figure) of the holding frame 100.

A suppressing operation type stop switch SW2 is provided. This stop switch SW2 is used when it is desired to manually stop the variable display operation of the variable display device 4 activated by the specific winning lower or the winning opening to 8.

Now, in the pachinko game machine configured as described above, if a ball hit into the game area la by the ball launcher 2 lands in any winning area, a predetermined number of prizes (usually 10 to 15) will be awarded. The ball is paid out. Furthermore, when the winning ball wins a specific winning prize lower or 8, the variable display device 4 is activated. And the segment type display LEDA-LEDD of the variable display device 4
The four numbers displayed can now be changed individually. Here, when the player presses the switch SW1 to SW2 or after a certain amount of time has passed, the operation of the variable display is thereby stopped.

At this time, if the combination of displayed numbers after the stop results in a pre-contracted result, a specific pattern is generated.

When a specific situation occurs, the special variable winning device 5 is converted from the closed state to the open state, and a winning area by the above-mentioned special variable winning opening 80 is temporarily opened and provided within the gaming area la. This changes the probability of winning there from zero to extremely high. As a result, the player is given a special opportunity to generate a large number of winning balls within a relatively short period of time and win a large number of prize balls.6 In this case, the situation caused by the above specific aspect is Depending on the combination of the above-mentioned displayed numbers, there are two types: "Jackpot" and "Mid-win."

A "jackpot" state occurs when a specific situation occurs in which all four displayed numbers match one of the predetermined specific numbers. The state of "Rin" occurs when a specific situation occurs in which any three of the three displayed numbers match one of the pre-contracted specific numbers. In other words, if you get four matches, you will get a jackpot, and if you get three matches, you will get a medium hit.

When a specific form of "jackpot" occurs, the special variable prize winning device 5 is set to an open state for a relatively long predetermined time (about 30 seconds). This dramatically increases the probability of winning a prize. Furthermore, while the special variable winning device 5 remains open, if a ball hits the continuous winning hole 81 set in the special variable winning hole 80, the special variable winning device 5 will temporarily return to the closed state. It will then be set to the open state again. In other words, the time period during which the special variable winning device 5 remains open is substantially extended. This provides players with many opportunities to win prizes.

Further, when a specific mode of "medium winning" occurs, the special variable prize winning device 5 is set to the open state only for a relatively short predetermined time (about 6 seconds). This results in a “jackpot”
However, the player is now given the opportunity to win significantly more prize balls than would normally be the case.

Here, the combination of numbers displayed on the variable display device 4 is changed randomly. Therefore, the special opportunities according to the above-mentioned specific mode are given almost equally, regardless of individual differences such as the level of gaming proficiency. This allows even beginners to enjoy the fortuitous opportunity of the above-mentioned specific aspect.

However, if the profits given to the players by the above-mentioned special opportunities are too large, there is a risk that unnecessary gambling will be aroused. Therefore, in order to avoid stirring up the gambling spirit, the control operations related to the occurrence of the above-mentioned specific mode are also performed together with the following control operations.

That is, when the above-mentioned "jackpot" state occurs, the number of winning balls into the special variable winning device 5 is limited to a certain limit (
10), the special variable prize winning device 5 is forced to immediately return to the closed state without waiting for a predetermined period of time (approximately 30 seconds) to elapse. Further, the set number of times the continuous winning hole 81 is kept open due to winnings is also limited to a certain number of times (10 times) or less.

In this way, the healthy interest of the players is not spoiled, and unnecessary speculation is not aroused.

On the other hand, although not shown in the drawings, when a specific mode such as "jackpot" or "medium hit" occurs, in addition to the above-mentioned control operation, depending on the type of the specific mode, for example, a sound effect such as a fanfare, etc. The display of effects using sound is also controlled. Note that the sound effect such as a fanfare, which will be described in detail later, is electronically generated and emitted from a speaker (not shown) built into the gaming machine.

This type of performance display allows players to experience fun things other than winning prize balls.

It is designed to make it easier to be guided inside.

Furthermore, an AC surface 41 is formed below the guiding plane 40b. As shown in FIG. 5, this AC surface 41 is approximately flush with the surface of the game board 1.
1, allowing interaction of batted balls flowing down the left and right game areas. As a result, the ball can easily fly into the second specific winning hole 8 or the special variable winning device t5.

As shown in FIG. 5, a recess forming wall 42 is fixed to the exchange surface 41. As shown in FIG. This recess forming wall 42 is the fastening part 4
1a and screws 43, forming a recess 42a that penetrates deep into the game board l.

A mounting surface 46 for mounting a variable display member 47, which will be described later, is provided at the back of this recess 42a.

As shown in FIG. 4, three display windows 46b are formed in a horizontal row on the L-numbered surface 46. As shown in FIG.

Further, as shown in FIG. 5, a support for fixing the variable display member 47 is provided protruding from the back thereof.

The variable display member 47 has a substrate 47a as shown in FIG.
It is attached and fixed behind the mounting surface 46 while being attached to the mounting surface 46 . As shown in FIG. 4, this variable display member 47 has three indicators arranged in a horizontal line. In this embodiment, this indicator is a segment type indicator LED using one light emitting diode as shown in Fig. 4.
A. LEDB and LEDC are used. Each display LE
DA, LEDB, and LEDC are each attached to the mounting surface 46 above.
It is positioned so as to face the display window section 46b.

Further, as shown in FIG. 4, one display window 40d is also formed in the center of the guiding surface 40b.

Another variable display member 48 is attached behind this display window 40d. This variable display member 48 has one indicator LEDD. This indicator LEDD is also a segment type indicator using light emitting diodes. As shown in FIG. 5, this variable display member 48 has a mounting board 48a.
At the same time, it is positioned and fixed by screws 43d.

Here, the segment type indicators LEDA, LEDB,
Each of the LEDC and LEDD is a type of character display element, and is configured to be able to arbitrarily and variably display a plurality of types of characters by combining segments that drive one light emission. In this embodiment, Arabic numerals from 0 to 9 are used as the characters. Therefore, the segment type indicator LEDA.

The LEDB, LEDC, and LEDD are configured such that each display can display any number from 0 to 9 depending on the combination of its segments. Note that the above-mentioned characters may be characters other than numbers, symbols, or pictures.

Furthermore, as shown in FIG. 4, at the bottom of the variable display device 4, there are four memory display lamps for displaying the aforementioned specific winning lower and the number of batted balls that won 8 (FIGS. 2 and 3). LED1 to LED4 are arranged in a horizontal line. These memory display lamps LEDI to LED4 are exposed through a through window 42d formed at the lower part of the white part forming wall 42, as shown in FIG.

As described above, the variable display member 47 and the memory display lamp LEDI-LED4 are both arranged at a position set back from the first surface of the game board. This is because the display member on which the variable display member 47 and the memory display lamps LED1 to LED4 appear is an alternating current surface, and since exchange of balls occurs frequently, it is necessary to protect them from hitting balls and prevent them from being damaged. It's for a reason.

In addition, in order to widen the visual range in which the variable display member 47 can be seen from the front, the recess forming wall 42 is tilted from the back toward the front side in a shape that widens toward the front, and the inner wall surface thereof is plated. The display contents of 47 are made clear. Furthermore, the rear surface of the recess 42a formed by the recess forming wall 42 allows the external incident light to reflect on the surface and enter the player's field of vision, so that the variable display member 47
In order to avoid obscuring the display, it is tilted slightly upward (approximately 8 to 10 degrees) with respect to the vertical plane.

On the other hand, on both sides of the guiding plane 40b, as shown in FIG. 4, a pair of jackpot display illumination means 27 made of semi-transparent colored members are provided. A lamp (not shown) which is a light source of this jackpot display illumination means 27 is mounted inside the illumination means 27 using a mounting board 27a and screws 43c, as shown in FIG. The mounting board 27a is 1
Although not shown, it is attached to a post protruding from the back side of the substrate of the variable display device 4 via a Cushmin material so as to improve ventilation. As a result, the variable display device 4 configured as described above can absorb vibrations caused by the light source lamp and efficiently dissipate heat generated from the lamp. The start switch swi detects (Fig. 3)
is activated (triggered) by When the variable display device 4 is activated, the four indicators LEDA, LEDB, and LE of the variable display members 47 and 48 disposed inside the variable display device 4 are activated.
The display contents of DC and LEDD are changed from a static state to a fluctuating state. And each display LEDA, LEDB,
The display numbers for each LEDC and LEDD are 0, 1, and 2.
,3. ...9, 0, 1°2, ... Throat begins to change (update) regularly. When a stop signal is received from the stop switch SW2 (Fig. 2) in this fluctuating display state, or after a certain amount of time has passed since the fluctuating state, each indicator LEDA, LED

Changes in the displayed numbers for each LEDC and LEDD are sequentially stopped at regular intervals. Then, the state returns from the fluctuating state to the stationary state. When the display stops changing, if the four numbers that appear on each display LEDA, LEDB, LEDC, and LEDD are in a specific combination (roll),
This creates specific features that offer particular benefits. In this embodiment, for example, all the numbers on the variable display member 47 are rlJ, r:N, r5", r7" or "9".
”, that is, the opening of those numbers (Zorome)
If it comes out, it is considered as the first specific mode called "r jackpot". Also, any three of the four numbers on the variable display members 47 and 48 may be NJ, r3J, r5'', r7'' or ``9''.
The second specific mode is ``When the eyes open (zorome), r offer.'' For other rolls, the specific aspect will not occur.

On the other hand, the jackpot display lighting means 27 on both sides of the variable display device 4 are driven to blink while the display on the variable display members 47, 48 is changing. Furthermore, display member 47.4
When the display of 8 stops changing, it's a "jackpot" or "
When the "offer" condition occurs, the blinking speed is controlled to become faster.

In addition, the memory display lamp LED1 at the bottom of the variable display device 4
~LED4 is controlled to light up as many times as the number of reservations on the variable display section.

6 to 9 show detailed configuration examples of the special variable prize winning device 5 shown in FIGS. 2 and 3.

The special variable prize winning device 5 shown in the figure first has a mounting board 50 for mounting on the game board 1.

This mounting board 50 has mounting holes 5 disposed on its periphery.
4, etc., it can be attached to the game board 1.

As shown in FIG. 7, a horizontally elongated opening 50a is formed in the center of the mounting board 50. As shown in FIG. A window portion 50b is formed immediately below this opening portion 50a. Moreover, in this opening 50a.

As shown in FIG. 6, a door-shaped special variable winning slot 51 that can be opened and closed is accommodated.

The back plate 52 is fixed to the rear end of the surrounding frame 54 with screws 55. In addition, the surrounding frame 54
As shown in FIG. 8, winning ball guiding channels 54a are formed on both sides of the ball, respectively.

This winning ball guide gutter 54a is formed at a position corresponding to the pair of winning devices 53 on the front surface of the mounting board 50. and,
The winning hole 53a acts to guide the winning batted ball to the back of the game board.

Further, on both left and right sides of the mounting board 50,
A winning device 53 is detachably attached. Each prize winning device 53 has a sixth prize. As shown in FIG. 7, a rotating member 70 and illumination means 53b are provided. Further, each of the winning devices 53 is provided with a winning hole 53a that opens upward at the upper end thereof. This prize opening 53
As mentioned above, a serves as a general winning opening.

Furthermore, as shown in FIG. 8, the mounting board 50 includes:
Through holes 50e are located at positions corresponding to the pair of winning devices 53.

0 is attached and fixed to the boss portion 50f on the back side. Its installation/
Fixation is done through the mounting hole 28b of the board 28a and the screw 28c.
It is done using.

Here, the special variable winning slot 51 is opened and closed in response to a specific aspect of the variable display device 4, and as shown in FIG. It is attached so that it can be opened and closed. When this special variable winning hole 51 opens, as shown in FIG. 7, a special variable winning hole 80, which is much wider than the general winning hole, is temporarily opened. This special variable winning hole 80 also includes a normal winning hole 82 which brings only a normal winning profit in which a predetermined number of prize balls are paid out.

A continuation prize opening 81 is formed that provides the right to continue or extend the specific mode described above.

Further, an actuating piece 51a is formed on one side (the right side in FIG. 7) of the special variable winning hole 51.

The end of the actuating piece 51a projects from a long hole 52a formed in the back plate 52 to the back side of the back plate 52. Then, it is adapted to be engaged with an electromagnetic solenoid, which will be described later, via a transmission member 65. As a result, the special variable prize receiving slot 51 is driven to open and close via its operating piece 51a.

FIG. 6 shows a state in which the special variable winning hole 51 is raised rearward, thereby closing the special variable winning hole. FIG. 7 shows a state in which the door-shaped special variable winning hole 51 is opened by falling forward.

On the other hand, on the back side of the mounting board 50, there are a pair of winning ball guide members 56a in an abbreviated shape along the lower edge of the window 50b,
56b is formed. This pair of winning ball guiding members 5
The tips of 6a and 56b are opposed to each other with an interval of one fishing line. Furthermore, an engagement recess 57a is formed at the tip of one of the winning ball guide members 56a. Along with this, an engaging portion 57b is formed below the base end side of the other winning ball guiding member 56b. Detector SW4 for detecting and counting the number of winning balls into the special variable winning hole 80 by this engaging portion 57b and the engaging recess 57a.
is designed to be installed and maintained. This detector S
W4 is a so-called IO count detector, and a non-contact proximity switch is used here. This 10-count detector SW4 is mounted so that the detection portion 31a at its tip faces within the space between the tips of the guide members 56a and 56b. Thereby, this detector SW4 can detect the winning balls guided by the guiding members 56a and 56b one by one.

Further, as shown in FIG. 7, a sorting room 58 is formed within the special variable prize opening 80. This sorting room 58 has its upper, lower, left and right sides surrounded by the surrounding frame 54 (FIG. 8), and its lower side has winning ball guide members 56a and 56b.
(Fig. 8). This sorting room 5
As shown in FIG. 8, the winning ball that entered 8 is the winning ball guiding member 56a.

56b, the particles are aligned and guided one by one and allowed to flow down through the detection section 31a of the 10-count detector SW4. After passing through the detector 31a, the winning ball is guided to one side (to the right in FIG. 8) by an arc-shaped direction regulating portion 50d shown in FIG. The arc-shaped direction regulating portion 50d is integrally formed at the lower part of the back surface of the mounting board 50, as shown in FIG.

Here, on the front surface of the back plate 52, as shown in FIG. 7, a pair of guide plates 52c are formed on both side edges of a window 52b formed in the center thereof. By this guide plate 52c, the upper part of the sorting room 58 is divided into the above-mentioned continuous winning opening 81 and normal winning opening 82.

Furthermore, as shown in FIG. 8, on the back surface of the back plate 52, a support projection 52 is provided along the upper end of the opening window 52b on the back surface.
d is formed. This support protrusion 52d has a pin 5.
9, a sensing piece 60 is suspended in a swingable manner. This sensing piece 60 is swingably suspended while
It is urged to go in and out of the continuous winning opening 81 shown in FIG. 7 from inside the opening window 52b. As a result, the batted ball that enters the continuation winning slot 81 (Fig. 7) is guided to a pair of guide plates 52c as shown in Figs. 7 and 8, and is guided through the rear opening window 52b. After the sensing piece 60 protruding forward is rotated backward, it flows downward toward the detection part 31a of the 10-count detector SW4, where it is detected one by one along with the batted balls that have won in the normal winning hole 82. It is now counted as follows.

As shown in FIG. 8, the sensing piece 60 is weakly elastically biased to protrude forward from the opening window 52b by the elasticity of the actuator 32a of the continuation condition detection switch SW3, which is a microswitch. There is. This continuation condition detection switch SW3 is for detecting a hit ball that has won in the continuation winning slot 81, and is attached to the back plate 52 via an L-shaped attachment member 61.

The continuation condition detection switch SW3 is positioned such that its actuator 32a comes into contact with the suppressing portion 60a bulged on the back surface of the sensing piece 60.

The upper end of the sensing piece 60 is formed with a pin hole 60b into which the pin 59 is inserted, and a stopper portion 60c that projects rearward to restrict the rotation range of the sensing piece 60. Also,
The support pin 59 of the sensing piece 60 that is engaged with the support protrusion 52d is prevented from being removed by fixing a rotation regulating portion 62a integrally formed on the holding member 62 to the support protrusion 52d.

Further, the continuation condition fulfillment display section 29 is inserted into the slit section 62d on one side of the holding member 62. This continuation condition fulfillment display section 29 indicates that the holding member 62
It is held and protected by a protection member 63 fixed to the boss portion 62c.

The hit ball that enters the continuous winning hole passes through the opening window 52d while pushing away the sensing piece 60.

During this passage, the continuation condition detection switch SW3 is activated and a detection signal is generated for each ball. After this,
Together with the batted balls that have won in the normal winning hole 82, they are guided to the detection section 31a of the count detector SW4 and detected one by one.

Further, as shown in FIG. 8, a continuation condition fulfillment display section 29 is attached to the back plate 52. This continuation condition fulfillment display section 29 is arranged so as to face into the opening window 52b. This continuation condition fulfillment display section 29 is driven to light up in response to a detection signal from the continuation condition detection switch SW3. This allows the player to know the establishment of the special condition that grants him the right to continue or extend the specific mode described above.

Furthermore, as shown in FIGS. 8 and 9, the back plate 5
A pair of boss portions 52f are provided on both sides of the elongated hole 52a on the back surface of No. 2.
is formed. As shown in FIG.
a is pivotally supported so that it can move up and down. The transmission member 65 is
It has the shape of a "to" character. Its tip portion projects forward from the elongated hole 52a. Furthermore, the transmission member 65
The tip is brought into contact with the upper surface of the rear end of the first actuating piece 51c. This operating piece 51c is formed in the special variable prize receiving hole 51 (FIG. 7). Further, the upper end of the fifth transmission member 65 is brought into contact with the operating end of the plunger 66a of the electromagnetic solenoid SQL. This electromagnetic solenoid SQL serves as the driving source for the special variable winning bag @5.

In FIG. 9, when the electromagnetic solenoid SQL is in a steady state in which it is not driven, the plunger 66a is pushed down by its return spring 66b, thereby pushing the transmission member 65 downward. Then, as illustrated by the dotted line in FIG. 9, the rear end side of the actuating piece 51c is pushed down and the special variable winning slot 51 is closed. As a result, the opening 50
a is closed, and therefore the special variable prize opening 80 is also closed.

On the other hand, when the electromagnetic solenoid SQL is energized by the occurrence of a specific mode in the variable display device 4 or the right to continue, the plunger 66a is driven upward.

As a result, the pressing force of the transmission member 65 is released, and the special variable prize receiving slot 51 falls forward under its own weight. As a result, the opening 50a is opened wide and the special variable winning hole 80 is temporarily opened.

As described above, the special variable prize winning device 5 is electrically opened and closed depending on the occurrence of a specific mode in the variable display device 4 and the above-mentioned right to continue.

Next, an embodiment of a control portion of a pachinko game machine to which the present invention is applied will be shown.

FIG. 10 Control device 10 for a pachinko game machine according to the present invention
0 shows the overall hardware configuration of 0.

The 11th @ is the waveform of the reset pulse φt and the CPU
210 is shown by a timing chart.

FIG. 12 shows means for generating the reset pulse φt.

FIG. 13 shows the I10 unit 240 of the control device 200.
Show nearby details.

FIG. 14 shows the configuration of the scale generating means 260 within the I10 unit 240.

First, in FIG. 10, the pachinko game machine 30 described above
The control device 200 of 0 is a program storage type CPU (central processing unit - micro-processor) implemented as a semiconductor integrated circuit device.
computer) 210.

That is, the control device 200 shown in FIG.
10. ROM (read-only storage device) 220, RAM (
random access memory) 230° address decoder 240. l10 (input/output) unit 250. Clock signal generation means 280. Reset signal generating means 29'O,
Address bus LA, data bus LB, and logic game 1
- It is composed of Gl, etc.

The CPU 210 is an 8-bit type (model number: Z8
0) is used. This CPU 210 has address terminals (A o to A16), data terminals (Do to D7),
Read control terminal RD, write control terminal WR, clock terminal C
It has functional terminals such as K and reset terminal R. Other important functional terminals include an interrupt input terminal (not shown). However, the interrupt terminal is not used here. Instead, a reset terminal R is used. The use of the reset terminal R will be described later. In addition, the CPU 210 used here
(280) has 16 address terminals (Ao to A, 5
) has an address space of 64 bytes. However, only about 2 bytes are used here.

The ROM 220 stores programs executed by the CPU 210 and fixed data. This R0M220 has a storage capacity of 2 bytes. This 2
The capacity of 6 bytes is very small compared to the address space 64 of the CPU 210 (Z80).The RAM 230 provides a work area for the CPU 210 and a storage area for variable data. A static type RAM 230 is used. Its storage capacity is kept very small, only 12
It's only 8 bytes.

In this case, since it is difficult to obtain a 128-byte RAM, a 1-byte RAM is actually used. By fixing the upper address terminal of the 1-byte RAM to the power supply potential side, the actual usable storage capacity is kept at 128 bytes.

As mentioned above, the storage capacity of each of the ROMs 220 and 230 is kept very small. This makes it possible to reliably eliminate the possibility of soft errors known as bugs, and also greatly reduces the possibility of malfunctions such as CPU runaway or jumping into an infinite loop. You will be able to reduce it. This makes it possible to achieve extremely high reliability even under harsh electrical and physical operating environments.

Furthermore, by reducing the storage capacity of the ROM 220 and RAM 230 as much as possible, modification by additionally writing a program becomes difficult. Even if a modification were made, it would be easy to discover and check because the storage capacity is small. This also provides the effect of preventing the Pachinko gaming machine from being misused due to unauthorized modification.

The address decoder 240 decodes address data (A o to A1.) issued from the CPU 210 to generate a plurality of alternative selection signals 81 to S9. The decoding operation is performed by activating either the successive control signal (RD) or the write control signal (WD). These two control signals (RD/WD) are CP
Emitted from U210. Both signals (RD/WD) are ORed together by logic gate G1. This logical sum becomes a control signal for the address decoder 240.

Selection signal 5l- output from address decoder 240
A part of 89 (S8, S9) is used as a chip select signal for the ROM 22 (1) and RAM 230. In addition, the other selection signals Sl to S7 are
It is used to control the input/output circuits within unit 250. In other words, the input and output channels are placed in the address space.

The so-called memory Matsubuto I10 system is adopted. By adopting this memory Matsubuto I10 method, input/output can be performed from any input/output circuit using the simple process of accessing a specific address, without the need for complex procedures such as opening and closing input/output channels. It is designed to perform an action.

Note that the memory Matsubuto I10 system had a problem in that part of the address space was occupied by the ■/○ areas and became narrow, so it was difficult to employ it in general microcomputer systems. However, in the control device 200 of this embodiment, as described above, the ROM 22
0 and RAM 230, each of which has a very small storage capacity, the above problem does not need to be considered at all.

The I10 unit 250 forms an interface (I/F) section between the control device 200 and the pachinko gaming machine main body 300. This I10 unit 250 is provided with a large number of input/output circuits, as will be described later. The operation of each input/output circuit is individually controlled by the selection signals 81 to S7. Although the individual configurations of the input/output circuit will be described later, for example, a decoder, a latch circuit, a driver, a buffer gate, an amplifier, etc. are used.

The clock generating means 280 uses a crystal oscillator X based on one frequency.
By using t a l (4 MHz), for example, a 2 MHz high precision clock pulse φk is generated. This clock pulse φ is applied to the clock terminal CK of the CPU 21O.

The reset signal generating means 290 generates the clock pulse φ
A reset pulse φt of a constant period is generated from k. This reset pulse φt is applied to the reset terminal R of the CPU 210. This reset signal generating means 290 is constructed simply and on a small scale using a counter or the like.

In this case, the reset pulse φt has a duty width, that is, a pulse width that is long enough to reliably reset the CPU 210. Also,
The pulse generation interval, that is, the period, is determined by the CPU 210.
is set so that the processing time is reliably longer than the processing time for executing the program instructions stored in the ROM.

FIG. 11 shows the waveform of the reset pulse φt and the above C
The operating states of the PU 210 are shown in time correspondence with each other.

The reset pulse φt shown in FIG. 11 has a pulse width of 15 μs and a period of 3 ms. This pulse width of 15 μs is a sufficient time to reliably reset the CPU 210. Also.

A period of 3 ms is sufficient time for the CPU 210 to execute the instructions stored in the ROM 220.

Further, as shown in FIG. 11 in time correspondence with the reset pulse φt, the CPU 210 controls the ROM 2
Each time a series of program instructions written in the memory card 20 is completed, it is forcibly reset to a complete initial state.

As a result, even if the CPU 210 were to malfunction, such as running out of control or entering an infinite loop, it would be automatically returned to a normal operating state by resetting every ams.

As a result, the worst situations, such as runaway or jumping into an infinite loop, which were most feared in a CPU-based control system, can be reliably avoided.

In other words, a kind of fail-safe works here to ensure that at least the normal operating state of the CPU 210 is maintained. In this way, the reliability necessary for a pachinko gaming machine is ensured.

Furthermore, since the reset interval of the CPU 210 is a constant cycle, by storing the number of resets in the RAM 230, a so-called soft timer function can be easily configured. Furthermore, since the reset interval is a relatively long time, for example 3 ms, it is possible to complete a relatively long timer of several seconds to several tens of seconds by simply allocating a small storage area of 1 or 2 bytes. can be configured easily and concisely.

For example, if the above reset interval is 3 ms, the RAM
By allocating 1 byte of the area to the timer area, one timer hour from 3 ms to 0.768 seconds can be obtained (3 ms x 256 bytes = 768
ms=0.768 seconds). By allocating an additional 2 bytes, one timer hour from 3ms to 196.608 seconds can be obtained (3ms x 256 bytes x 256 bytes = 196608m5 = 196.608 seconds).

As a result, even if the RAM area is only 128 bytes, for example, it is possible to easily configure a large number of timer functions necessary to individually control various functions within the pachinko gaming machine main body 300. . Incidentally, it is possible to obtain a comparatively long one hour timer of several seconds to several tens of seconds, which is necessary to control the operation of the above-mentioned special variable prize winning device 5 (Figs. 2, 6 to 9), with only 2 bytes of RAM area. I can do it.

In FIG. 11, the halt state (standby state) is maintained from the time the program command is executed until the next reset. This halt state is set by executing a halt instruction at the end of the program.

In other words, the above program ends with a halt instruction.

FIG. 12 shows an example of the configuration of the reset pulse generating means 290 (FIG. 10) that generates the reset pulse φt. As shown in the figure, the reset pulse generating means 290 includes a preliminary frequency dividing circuit 291. In the same figure, Gin is the count input, Cou
t indicates the count-up output.

With the above configuration, it is possible to ensure reliability as a pachinko game machine and to configure various functions necessary to control the operation of the pachinko game machine.

Next, the configuration near the I10 unit 250 will be explained.

The I10 unit 250, as shown in FIG.
A buffer gate 251 and latch circuits 252 to 256 are provided as input/output circuits.

The operations of these input/output circuits (251-256) are controlled by the selection signals 81-S6 mentioned above.

In addition, each input/output circuit (251 to 256) is connected to a data bus L.
It is connected to the CPU 210 (FIG. 10) via D. Data exchanged between the pachinko gaming machine main body 300 side and the control device 200 side is carried out via the data bus LD.
It is now available to be posted on. Furthermore, in addition to the input/output circuits (251 to 256), a scale generating means 257 is provided. The operation of this scale generating means 257 is also controlled by the selection signal S7 mentioned above.

Among the input/output circuits (251 to 256), the buffer gate 251 constitutes an input circuit. This buffer gate 25
1 receives detection signals from various detection means (SW1 to SW4, etc.) provided on the pachinko gaming machine main body 300 side, and puts them on the data bus LD in the control device 200. In this case, the detection means is the start switch S mentioned above.
W.I.

Stop switch SW2. Continuation condition detection switch SW3
, 10 count detector SW4 (Fig. 3.7).

Furthermore, among the input/output circuits (251 to 256), latch circuits 252 to 256 form output circuits.

Further, latch circuits 252 and 254 therein each include a decoder. These decoders respectively decode each display data of the light emitting diode type segment type display LEDA-LEDE on the pachinko game machine main body 300 side. The display data is transmitted via the data bus LD.
Given from PU210.

The functions of each output circuit (252-256) are as follows.

That is, the latch circuits 252 and 253 are connected to the segment type display L of the variable display device 14 (FIGS. 2 to 5) described above.
The EDA-LEDD is dynamically driven for display. The display data is given from the CPU via the data bus LD. Note that each latch circuit 252, 253 is provided with a driver 262, 26 for increasing the driving force of its output.
3 are attached to each.

The latch circuit 254 drives the segment type display LEDE. As mentioned above, this indicator LED is
This is to display the number of times the special right continues when a specific form of "jackpot" occurs.

The display data is given from the CPU via the data bus LD.

The latch circuit 255 individually drives the memory display lamps LED1 to LED4 made of light emitting diodes to turn on. Control data for the lighting is given from the CPU via the data bus LD. These memory display lamps LED1 to LED4 are
As mentioned above, it is used to display the number of retained batted balls that won a prize in the specific winning lower, 8 (Figures 2 and 3).

The latch circuit 256 individually drives the drive source and display means on the pachinko game machine main body 300 side via the driver 266. The driving source in this case is the electromagnetic solenoid 66 (FIG. 9) that drives the special variable winning device 5 mentioned above to open. In this case, the display means is the continuation condition fulfillment display section 29 (the third
, 9).

Further, the scale generating means 257 generates a sound source having a predetermined scale. The generated sound source is amplified by an amplifier 267,
It is given to the speaker SP for generating sound effects on the pachinko game machine main body 300 side. The scale of this sound source is set by data given from the CPU via the data bus LD.

FIG. 14 shows the configuration of the scale generating means 257.

As shown in the figure, the scale generating means 257 is comprised of a latch circuit 257a that holds scale setting data and a presettable counter 257b.

The latch circuit 257a connects the CPU via the data bus LD.
Holds the scale setting data given by. This latch circuit 257a reads and holds the data on the data bus DL when the selection signal S7 becomes valid. The held data is preset to the count contents of the presettable counter 257b.

The presettable counter 257b is a type of down counter, and is decelerated (decremented) by 1 by the clock pulse φk, and its initial count is preset by the latch circuit 257a. Each time the preset count is decelerated to "0", the data held in the latch circuit 257a is newly preset.

Here, the output state of the carry terminal (count output terminal) Crry of the presettable counter 257b changes from H (high level) to low level every time the count is decelerated to [)J. Alternatively, the signal alternately changes from L (low level) to H (high level). As a result, a signal that alternately transitions between H (high level) and L (low level) is obtained from the carry terminal Crry. This signal is then used as the above-mentioned sound source. This sound source is amplified by an amplifier 267 and is provided to a speaker SP for generating sound effects on the pachinko game machine main body 300 side. At this time, the scale of the sound source is determined by the preset value. Moreover, if the preset value is small, the period of the above-mentioned transition becomes long, and the pitch becomes low.

Moreover, if the preset value is small, the period of the above-mentioned transition becomes short, and the pitch becomes high.

The preset value is then set by the CPU 210 (first
(Fig. 0) can be arbitrarily variably set. As a result, the control device 200 controls the pachinko game machine main body 300.
You can optionally generate sound effects such as fanfare sounds.

Note that the presettable counter 257b may be an up counter.

Next, the software configuration of the above-mentioned control device 200 will be explained along with its operation.

FIG. 15 shows the above-mentioned control device 200 (FIGS. 10 and 11).
The entire processing flowchart is shown.

FIG. 16 shows an enlarged part of the processing flowchart.

First, Table 1 below shows the CPU 210 of the control device ff1200.
(FIG. 10) shows the allocation contents of the at-tray space section accessed by a memory map, and the addresses are expressed in hexadecimal numbers of O-F.

In Table 1 below, the address space range accessed by the CPU 210 is 6 that the Sono CPU (Z80) 210 has.
4 byte address space (addresses 0000 to FFFF)
Two bytes between addresses 0000 and 4000 and addresses 0000 and 07FF are allocated to the ROM area. Also, 0800-0
128 bytes up to address 87F are allocated to the RAM area. And 1000.1800,2000,
1 each at 2800, 3000° 3800.4000
The I10 area is allocated for each byte. In this case, the gaps in each of the 10 areas are not used. Therefore, C
The size of the address space that the PU 210 actually accesses is only about 2 bytes.

Further, Table 2 below shows the variable storage contents of the RAM 220 (FIG. 10) using a memory map.

Table 2 RAM Area Memory Map Next, the operation of the control device 200 described above will be explained with reference to FIG. 15 and Table 1.2 above.

In FIG. 15, the CPU 210 of the control device 200
It is forcibly reset by hardware by the above-mentioned reset pulse φt (Fig. 10.11.12). This reset causes the CPU to start up from a complete initial state. CP started from initial state due to reset
First, U starts accessing the ROM 220 and sequentially reads and executes program instructions stored therein.

As a result, a series of processes shown in FIG. 15 are started.

When execution of a program instruction is started, a stack pointer is first set (R1). Next, it is checked whether start data indicating the beginning of the backup area (addresses 0838 to 0843) and end data indicating the tail are set (R2-R3-R14-R15
).

Here, in the first operation after the control device 200 is cold started (started by turning on the power), initial settings of the program are performed (R17).

In this initial setting, all variable data such as output data and count data stored in the I10 area, for example, are initialized. Thereafter, the start data and end data are set (written) (R11).

This start data and end data are stored in the RAM 230.
For example, a value such as A 5 (2*number of times 100101) is used, which can reliably reflect storage errors and the like. Further, after transferring the initialized data to the backup area, the CPU executes a halt command to stop the processing itself (R12-R13). Then, there is a reset by the primary reset pulse φt.

The operating state of the control device 200 is initialized as described above.

After this initialization of the control device 200 is performed, the CPU:
Every time the reset pulse φt is issued, the main routine R
1 to R13 are executed sequentially. In this main routine, as shown in FIG. 15, the following processing is executed.

R1: Set stack pointer.

R2, R3: Check the end data of the backup area.

R4 start switch SWI, stop switch SW
2. Continuation condition detection switch SW3.10 Performs input processing to detect each rising edge of count detector SW4.

This is done by referring to the previous detection signal and each current state. The state of the previous detection signal is stored in the buffer area.

This memory state is constantly updated.

The number of activations of the R5 start switch SW1 is memorized.

The aforementioned variable display device 4 (FIGS. 2 to 7) is activated by the specific winning ball detection operation of the start switch SWI. In this processing routine, the number of winning balls, ie, the number of times the start switch SW1 is activated, is stored until the variable display operation of the activated variable display device 4 is stopped. If there is a memory of this number of operations, that is, the memory value is 1
If this is the case, the variable display device 4 will be activated again after the variable display operation has been completed. Then, when the variable display device 4 is restarted, the stored value is decelerated (decremented) by one.

That is, in this processing routine, the specific winning lower, 8
(Figures 2 and 3) performs processing to preserve the right to start the game resulting from winning.

R6: Performs fraud check processing for the 10 count detector SW4.

It is logically determined whether the function of the 10-count detector SW4 is impaired due to a disconnection or short circuit of its connection or wiring, based on the input state from the detector SW4.

R7': Update the timer values of various timers stored in the RAM area.

R8: Set the operation parameters (scale data) of the scale generation means 257.

In this processing routine, processing is performed to output scale setting data for generating sound effects such as fanfares.

R9: Performs control processing for various display means, electromagnetic solenoids, etc.

In this processing routine, the above-mentioned jackpot display lighting means 27 and the continuation condition fulfillment display section 29 (Figs. 3 and 8) are blinking controlled, and the electromagnetic solenoid SQL (Fig. 9) in the above-mentioned special variable prize winning device 5 is controlled. will be carried out.

R10: Performs various determination and control processes related to winning.

Here, a series of processes related to the operation control of the variable display device 4 and the occurrence of specific aspects such as "big win" and "offer" are performed.

The detailed contents of this routine RIO are shown in FIG.

R1l: Performs setting (writing) processing of start data and end data indicating the beginning and end of the backup area described above.

R12: Perform processing to transfer variable data such as output data to a backup area.

After the above-mentioned main routines R1 to R12 are executed one by one, a halt instruction is executed in the last processing routine R13. This causes it to enter a standby state in which it stops continuing the process.

Furthermore, when an error occurs in the end data due to some abnormality during the execution of the main routines R1 to R12 described above, a routine R for checking the end data is provided.
A branch is made from 2-R3 to routines R14-R15 for checking the start routine. and.

If an error also occurs in the start data in the branched routines R14-Rl5, the routine R17 for initializing the program is re-executed.

The state of the control device 200 is returned to the state immediately after the cold start. In this way, fail-safe operation is performed to guide the control state of the control device 200 in a safe direction when an abnormality occurs. On the other hand, if the error occurs only in the end data and there is no abnormality in the start data, routine R16 is executed so that the backed up data is retransferred to the main work area 0800 to 080A of the CPU. Become. As a result, if the degree of error is minor, it is possible to automatically return to normal operation while preserving the intermediate state of control.

FIG. 16 shows a detailed flowchart of the above-mentioned prize entry processing routine RIO.

As shown in the figure, this prize winning processing routine R10 is
Consists of subroutines 01 to R122.

Processing related to a specific winning, that is, the variable display device 4
A series of controls related to the operation control and the occurrence of the specific mode are executed using process numbers 1 to 8. In other words.

The above-mentioned start switch SWI and stop switch S
W2. A processing number is set based on each detection state of the continuation condition detection switch SW3 and the 10 count detector SW4.

Then, by selectively executing a subroutine prepared in correspondence with the set processing number, it is possible to cause the pachinko game machine described above to perform a specific winning-related processing operation. Here, the process number is set to any one from No, O to N008. In this case, in process N000, only a check is performed as to whether or not the operation start conditions of NO, 1 to N008 are satisfied, and no process related to a specific winning is performed. Processing related to a specific prize is performed when any processing number from No. 1 to No. 8 is set.

Primary subroutines R111 to R118 are prepared corresponding to each process number from No. 1 to No. 8.

That is, when the process number is set to No, 1, routine R11l is executed. In this routine R111, processing is performed to start the variable display device 4 based on the detection of the start switch SW1. After execution of this process, the next process number No. 12 is set.

If the processing number is set to No. 2, routine R1
12 is executed. In this routine R112, processing is performed to stop the operation of the variable display device 4 in stages based on the detection of the stop switch SW2. At this time, a process is performed in which a randomly set time is partially inserted into the time until the display operation stops. This randomizes the display contents after the operation is stopped. After this process is executed, the next process number No. 3 is set.

If the processing number is set to N003, routine R1
13 is executed. In this routine R113, processing is performed to determine whether or not a specific mode has occurred based on the result of stopping the variable display device 4.

The determination is made based on the stopped display content.

When a specific aspect of "jackpot" is determined, processing number No. 5 is set. In addition, if the specific mode of [offer] is determined, the processing number No.

6 is set. In other cases of loss, processing number No. 8 is set.

If the processing number is set to No. 4, routine R1
14 is executed. In this routine R114, control processing is performed when a specific aspect of a "big win" occurs, for example, control to open the special variable prize winning device 15. In addition, timer processing is also performed, thereby limiting the opening driving time to a relatively long predetermined time (about 30 seconds). Furthermore, blinking driving processing for the related display means is also performed. After execution of this routine R114, process number No. 7 is set in order to determine whether or not to continue.

If the processing number is set to No. 5, routine R1
15 is set. In this routine R115, by setting the operating parameters of the scale generating means 257, a process is performed to generate a fanfare sound accompanying the occurrence of a specific form of a "big hit".

After execution of this routine R115, the process number No.

4 is set.

If the processing number is set to No. 6, routine R1
16 is executed. In this routine R116, control processing 1 when a specific mode of "medium hit" occurs, for example, control to open the special variable prize winning device i5 is performed. In addition, timer processing is also performed, thereby limiting the opening drive time to within a relatively long predetermined time (about 6 seconds). Furthermore, blinking driving processing for the related display means is also performed.

After the predetermined time has elapsed, processing number No. 8 is set.

If the processing number is set to No. 7, routine R]
17 is executed. In this routine R117, the special variable prize winning device 5 is re-driven based on the detection of the continuation condition detection switch SW3. This process is executed when a specific form of "jackpot" occurs. After execution of this routine R117, the next process number No. 8 is set.

If the processing number is set to N008, routine R1
18 is executed. In this routine R118, processing is performed after the state of "big win" or "medium win" is completed, and when the operation of "r medium win" is completed, the processing number is changed to N01 after a delay time of about 1 second. Set to . Further, when the "jackpot" operation is completed, a delay time of about 3 seconds is set, and if it is confirmed that the continuation condition for the "jackpot" state is met during that time, the processing number is set to No. 4. If the continuation condition is not met, the process number is No. 0
Set.

Here, the above-mentioned series of winning-related processes are processed by process number No.
It is started by setting 1. This N
The processing number 001 is set when the number of times the start switch SWI is turned ON is stored (routines R109 and R120).

As described above, while updating the processing number, the operation control of the variable display device 4 and the winning-related processing associated with the occurrence of the specific mode are performed.

Next, FIG. 17 shows the configuration of the 10-count detector failure detection means 03 that detects whether the function of the 10-count detector SW4 is normal or not.

As shown in the figure, in this type of pachinko game machine with accessories, a special variable winning device 5 detects a winning ball.
Count detector SW4 and this 10 count detector SW
4, and a winning restriction means 02 which limits the number of winning balls to the special variable winning device 5 to a certain value or less (usually 10 or less) based on the detection output of 4, and the benefit brought to the player by this means is limited to an appropriate range.

The IO count detector SW4 is as described above.

All the winning balls that have won in the special variable winning device 5 are detected. This detection output is the ON/OFF switch (ONlo).
FF) is output. Based on the detection output of this 10 count detector SW4.

The number of winning balls entering the special variable winning device 5 is counted.

When the counted value reaches a certain limit number (usually 10), further winnings are restricted by, for example, stopping the operation of the special variable winning device 5.

In addition to the above-mentioned functional means, the 10-count detector S
A 10-count detector failure detection means 03 is provided for logically determining whether or not the function of W4 is normal. This 10-count detector failure detection means 03 is comprised of routines R6 and R107 of the flowchart shown in FIG. However, its configuration is not independent; as shown in FIGS. 18 and 19, the program storage type microcomputer 210 stores it in one continuous program together with the other processing means mentioned above. They are inseparably integrated and constituted.

FIG. 18 shows a part of the routine R6 in FIG. 15 in detail, and FIG. 19 shows the routine R10 in FIG.
The flowchart in FIG. 18 (R
601 to R605) and the flowchart in FIG. 19 (
As shown in R107-1 to R107-10), the count detector failure detection means 03 has the above-mentioned award restriction means 0.
It is integrally constructed in an inseparable state with other components such as 2. Such a configuration makes it extremely difficult to tamper with the system by separating and losing only the function of the 10-count detector failure detection means 03. If part 1
In order to lose the function of the 0-count detector failure detection means 03, it is necessary to also lose other functions. what if,
Even if it were possible to remove only the function of the IO count detector failure detection means 03, in that case it would be necessary to completely rework the program executed by the microcomputer 210.

In any case, it is extremely difficult.

Here, in FIG. 17, the 10-count detector failure detection means 03 is a ball detection means 04 that detects the operating state of the 10-count detector SW4.

Clock means 05 for measuring the duration of the detection output of the 10-count detector SW4 provided via this detection means 04
, the time measured by this clocking means 05 is constant (
5 seconds) or more, the special variable prize winning device 5 will operate.
and an execution stopping means 07 for stopping the execution of the prize-winning operation.

As a result, as shown in FIG. 18, the 10 count detector SW4 is in the detection state (on (O
N) status) is output continuously, an inability detection process is performed. In this case, the first
The timer T on in FIG. 8 corresponds to the timer 05 in FIG. 17. Further, the routine R603 in FIG. 18 corresponds to the execution stopping means 07 in FIG. 17.

Further, the 10-count detector failure detection means 03 is provided with logic means 06 for detecting the logical product state of the non-detection output of the 10-count detector SW4 and the detection output of the above-mentioned continuation condition detection switch SW3. . As described above, this continuation condition detection switch SW4 is for detecting the winning ball that has entered the continuation winning opening 81 in the special variable winning device 5. If a winning ball is detected from this continuation condition detection switch SW3, the 10 count detector SW4
Winning balls should also be detected.

As a result, as shown in FIG. 19, the 10-count detector SW4 is in a non-detection state (OFF
) status) is output continuously, an inability detection process is also performed.

Here, even though a winning ball is detected from the continuation condition detection switch SW3, if a winning ball is not detected from the upper ii1!10 count detector SW4, the execution stopping means 07 operates and outputs By clearing the data, etc., the winning-related control operations can be forcibly returned to the initial state immediately after the power is turned on. Therefore, the above-mentioned "jackpot" state is also forcibly eliminated. In this case, the routine R107-9 in FIG. 19 corresponds to the execution stop means 07 in FIG. 17.

In this manner, the function of the 10-count detector SW4 is prevented from being illegally canceled.

At the same time, it is actually almost impossible to illegally cancel the function of the count detector failure detection means 03. This makes it possible to reliably prevent unauthorized use of the pachinko game machine equipped with the special variable prize winning device 5 and equipped with accessories.

[effect] As explained above in the description of the embodiments.

The pachinko game machine according to the present invention is provided with a count detector failure detection means for logically determining whether or not the function of the count detector for detecting winning batted balls in the variable winning device is normal. By integrally configuring the I111 means such as the above-mentioned variable prize winning device and the like in an inseparable state using a program storage type microcomputer, it is possible to greatly prevent the function of the above-mentioned count detector failure detection means from being illegally canceled. This makes it possible to reliably prevent unauthorized use of a pachinko game machine equipped with a variable prize winning device. This effect can be obtained.
