Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a pachinko gaming machine equipped with a function of restricting the opening/closing operation of a door that opens and closes in a specific winning area, and in particular, when an abnormality occurs in such function. This invention relates to a pachinko game machine that prevents unauthorized modification of a pachinko game machine that has passed examination and certification based on the Entertainment Business Act by making it inoperable.

Conventional technology Conventionally, in addition to the normal winning area, first and second specific winning areas are provided, and when a game ball flies into the first specific winning area, the second area is opened and the winning opportunity is skipped. A pachinko game machine of the type in which the player's interest is increased by increasing the number of players on a daily basis is known as Japanese Patent Laid-Open No. 59-40882. Furthermore, in order to avoid unnecessarily arousing the gambling spirit of players, in this type of gaming machine, the maximum number of openings of the door that opens and closes the second specific winning area is limited. It is known as Publication No. 59-115070. However, even with such gaming machines, if the detection switch that detects the number of times the door is opened is tampered with, for example, at the gaming parlor, the limiting function will be lost and the winning profits will be rationalized. I can't.

Problems to be Solved by the Invention The present invention provides that when an abnormality occurs in the detection means that detects winnings in the winning area that is opened and closed by the opening and closing door, and the winning condition restriction function is lost, the opening and closing door is closed and the player To provide a pachinko game machine that prevents unauthorized modification of a pachinko game machine that has passed examination and certification based on the Entertainment Business Law by avoiding giving excessive winning profits to players.

Means for Solving the Problems As shown in FIG. 1, the pachinko game machine of the present invention has an opening/closing function of 17i! a winning area bltA having a number of 16 and enabling winning of game balls when the opening/closing door is opened; a driving means B for opening/closing the opening/closing door a; In a pachinko gaming machine, the pachinko game machine is provided with a detection means C for detecting a detection result by the detection means C, and a control means for controlling the drive means B so that the opening/closing door 16 opens and closes according to the detection result by the detection means C. a second detecting means E disposed upstream of the detecting means C and capable of detecting a winning in the winning area t4A at the latest by a predetermined time earlier than the detecting means C; After that, when the detection means C does not detect a winning prize within the predetermined time, the control means controls the opening/closing door 1.
6 is configured to control the driving means B so as to close.

Operation When the opening/closing door 16 opens and the second detecting means E arranged upstream of the detecting means C detects a winning in the winning area A, when the detecting means C is in normal operation, a predetermined amount of time is reached from the time of this detection. The detection means C detects winning in the winning area A within the time.

On the other hand, if the winning is not detected by the detecting means C even after the predetermined period of time has elapsed after the winning is detected by the second detecting means E, the operation of the detecting means C is abnormal.
The control means closes the opening/closing door 16 via the drive means 8,
Prevent any subsequent winnings.

Example Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 2 to 4, the game board 1 of the pachinko game machine includes regular winning holes 2 to 8, as well as chips 11 to 13 that do not form the first specific winning area and second specific winning holes. Attackers 14 as areas are provided at predetermined positions, and a central pocket 15 into which a game ball 100 can fly is provided approximately at the center of the interior of the attacker 14 through the upper end opening.
It constitutes a specific winning area. The attacker 14 has an opening/closing door 16 on its front side, and the opening/closing door 16 is driven by a solenoid 17 (FIG. 5) as a driving means fixed on the back side of the game board 1, so that the upper part of the attacker 14 is moved to the front side of the game board 1. It is designed to move and open.

A starting switch (Go switch) 18 (Fig. 5) consisting of three normally open microswitches arranged in the middle of the winning ball guide path (not shown) provided on the back side of the game board 1 is opened when a winning ball passes. Then, winnings in Chatkas 11 to 13 are detected. In addition, a count switch 19 consisting of a normally closed proximity switch as a detection means is disposed within the winning ball falling path defined by the peripheral wall of the central pocket 15 and the guide plate 20, and is arranged in the winning ball fall path defined by the peripheral wall of the central pocket 15 and the guide plate 20, and is configured to detect whether or not the winning ball falls through the central pocket 15 or not. When the game ball 100 enters the prize in the accumulator 14, the opening is activated to detect such a prize. Further, a center pocket switch (V switch) 21 consisting of a normally open microswitch serving as a WX2 detection means moves the operating piece 21a to the center pocket 15.
It is arranged at a position upstream of the count switch 19 so as to face the middle part of the pocket 15, and detects winnings in the pocket 15.

Reference numerals 22 and 23 indicate the upper and lower digital displays arranged in the center of the game board 1, and reference numerals 24 and 25 indicate the central pocket 1.
5 and Chiv Tsuka 11 to 13, the center pocket lamp (V lamp) blinks or lights up when winning a prize, and the starting lamp (Go clamp, code 2G) is a rotating LED (described later) installed on the front of the frame of the Yugi. This is a normally open push-button stop switch for stopping the operation.Also, a speaker 27 (FIG. 5) is attached to the back of the game board 1.

FIG. 5 shows an outline of the circuit configuration of the pachinko game machine, and the various switches 18, 19, 21, and 26 mentioned above are used to send various winning display signals S1 at levels corresponding to the open/close states of these switches.
~S3 and a switch input detection circuit 30 that outputs an LED rotation stop signal S4, and is connected to an input port of an input/output circuit 40. Central processing unit (C
PU) 50 is connected to the input/output port of the input/output circuit 40 via a bus, and also includes a read-only memory (ROM) 51 and a CPU 5 that store control programs, etc., which will be described later.
The RAM 52 is connected to a random access memory (RAM) 52 that stores various calculations and determination results executed in the RAM 52. This RΔM52 has a data storage area, and the CPU5
According to the write command of 0, the winnings to Chukka 11 to 13, the winnings to pocket 15, and the L are written to each specified location in the storage area.

Command data used for determination and solenoid 1
Control output data for driving various operating units such as 7 and the like are stored. 53 to 55 indicate a clock circuit, a reset circuit, and a power supply circuit 55, respectively. Also, 61 to 66 is
These are various drive circuits that respectively drive corresponding ones of various operating parts such as the opening/closing door drive solenoid 17 according to control outputs from the CPU 50 via the input/output circuit 40, as described later.

FIG. 6 shows a flowchart of a control program executed by the CPU 50, and the program is executed periodically in accordance with a reset signal from the reset circuit 54. First, in step 601, if the power is turned on, the process moves to initialization processing (step 602), and the switch flag, winning number data, command data, control output data, etc. in the RAM 52 are cleared, and the refresh counter in the CPU 50 ( (not shown) generates random numbers and uses them as display data on the lower display 23.

Next, the process moves to step 603, and if there are no winnings in Chutka 11 to 13 yet, the starting memory number representing the number of winnings in Chutka is O, so all of the answers to the determinations in steps 605 to 609 are negative, Door drive solenoid 17. The lamps 24, 25 and the speaker 27 are kept de-energized (step 610) and the current loop of the program ends.

On the other hand, if the game ball wins any of the chatkas 11 to 13, the start switch 18 is closed, so step 60
The determination result in step 3 is affirmative, and 1 is added to the starting memory number (step 6o4). Next, since the last content of the command data is 0, when the process reaches step 611 via steps 605 to 610, it is determined that there is a starting memory number, and this memory number is displayed on the upper display 22. Then, 1 is subtracted from the starting number (step 612), the software timer is set to a predetermined maximum LED rotation time (step 613), and then the command data is updated from 0 to 1 indicating that the LED is rotating (step 614). ).

The answer to step 605 of the next loop will be affirmative, and LE
D rotation processing is performed (step 615), and the lower L E
Each display section 23a of the lower display 23 is controlled by the D drive circuit 63.
The display contents of ~23c are each updated by 1 at different cycles, and stop when the predetermined longest LED rotation time has elapsed or when the pushbutton stop switch 26 is operated, and at this time, the command data is updated to 2 indicating that the LED rotation has stopped. . and,
During the LED rotation process, the starting lamp 25 lights up in response to each output of the starting lamp and sound drive circuits 65 and 66, and a rotating sound is output from the speaker 27.

In the next loop, LED rotation stop processing (step 616)
is performed, the display contents of each of the display sections 23a to 23c are sequentially stopped, and the command data is updated to 3 indicating that the LED is being judged.

Therefore, in a loop directly after completing the LED rotation stop l process, the process moves to the LED determination process (step 617), and the display contents of the lower display 23 are transferred to the corresponding RAM.
The determination is made based on the display data in 52. As a result of the determination,
If the 3-digit digital number displayed on the first to third display sections 23a to 23c of the display 23 is not a zero, the software timer is set to a first predetermined time, for example, 0.4 seconds, while if it is an even number, If it is a hit, the second predetermined time is, for example, 6 seconds, and if it is an odd-numbered zero (jackpot win), the third predetermined time is, for example, 20 seconds. Also, the command data is updated to 4, which indicates that the actuator is being opened.

In the next loop, the attack opening process is executed (step 618), and the solenoid drive circuit 61 opens the solenoid 17.
is activated, and the opening/closing 1i16 of the attacker 14 is opened/closed at the time set according to the combination of the numbers displayed on the display 23. However, when winning a jackpot, the opening/closing door 16 is opened when the number of winnings to the attacker 14 reaches 10, even if the third predetermined time has not elapsed.

Furthermore, while the actuator is being opened, the starting lamp 25 is turned on and an opening sound is output from the speaker 27. Furthermore, when a prize is won in the central pocket 15, the central pocket lamp 26 is blinked, and the number of winnings is set to a predetermined number of times, for example, 1.
R the flag information that displays winnings unless it reaches 0 times.
Stored in AM52.

Attacker Kaisei, 1st. When the second or third predetermined time has elapsed, the command data changes to 5 indicating that delay processing is in progress.
will be updated and the delay processing will be executed next time in the loop (
step 619). That is, if it is determined that there is no winning in the central pocket 15 based on the flag information mentioned above, the process moves to the above-mentioned step 610, while if there is such a winning, the attacking force 14 is opened again. Therefore, the attacker 14 is allowed to open the prize ten times in succession on the condition that the central pocket 15 is won.

Then, during actuator opening and delay processing, the display 2
3. Number of consecutive wins in central pocket 15 and attacker 1
The number of winnings to the attacker 14 during each opening operation of 4 is displayed.

As mentioned above, in the pachinko game machine of this embodiment, if the attacker 14 wins 10 times, the opening 1116 is changed to 111 to prevent further wins so as not to arouse the player's gambling spirit. However, for example, between the contacts of the normally closed count switch 19 or between the lead wires 19a and 19b.
(FIG. 5) If the switch 19 is short-circuited, the switch 19 will not always detect a winning, regardless of whether or not the attacker 14 actually wins. Therefore, for example, at the game parlor side, the count switch 19 is set to give an excessive winning profit to the player.
In this embodiment, in the above-described attacker creation process (step 618 in FIG. 6), in addition to the control programs (not shown) for the various operations described above, the abnormality shown in FIG. An identification program is run to prevent this type of unauthorized modification.

That is, during the attacker opening process (step 618 in FIG. 6), the CPLJ 50 determines whether the short circuit timer has timed up (step 701 in FIG. 7). The timer is made of software and stores a stored value for a predetermined period of time, for example 1.
If the short circuit timer has not timed up yet in step 701, the process moves to step 702 and the stored value of the timer is set to r.
It is determined whether or not it is OJ. The short-circuit timer is reset when the power is turned on to the pachinko game machine, and its stored value is initially rOJ, so the process moves to step 705 and determines whether or not the switch 21 is turned on, that is, the short-circuit timer is transferred to the attacker 14 via the central pocket 15. It is determined whether or not there is a winning prize based on the output level of the V switch 21. ■Switch 21
If the is not turned on, the stored value of the short circuit timer is stored in RAM.
52 and stored (step 708), this program ends.

After that, the program is executed according to the above-mentioned path until the switch 21 is turned on. When the switch 21 is turned on, the number of winnings to the attacker 14 is determined based on the data in the RAM 52 (Step 706), and if there are any winnings yet. If not, the timer memory value is set to "1" in step 707, and the program is terminated via step 708. Next time in the loop, the memorized value is not 10, so the memorized value is changed to "
1'' is added, and it is determined whether the count switch 19 is turned on or not based on the output level (step 70).
4). As mentioned above, the switch 21 is located in the central pocket 1.
Since it is placed upstream of the count switch 19 facing the middle part of the pocket 5, when the attacker 14 wins through the center pocket 15, if the count switch 19 is operating normally, ■ after the switch 21 is turned on. The count switch 19 is turned on at the latest within the above-mentioned predetermined time (1.4 seconds), usually about 0.4 seconds later (Fig. 8). Therefore, if the count switch 19 is normal, it will turn on before the short circuit timer times out. The switch 19 is turned on and the short-circuit timer is reset (step 709), and the pachinko game machine is kept in use until the next abnormality determination is executed when the V switch 21 is turned on next time.

On the other hand, if the count switch 19 is not turned on after the switch 21 is turned on, the memory value of the short circuit timer is updated every time this program is executed, and the value stored in the short circuit timer is updated for a predetermined period of time, for example, 1.4.
If seconds are preferred, time-up of the timer is determined in step 701, and the process proceeds to step 710, where abnormality processing is executed.

The abnormality processing is carried out by the CPU 50 in the solenoid drive circuit 6.
1 to the solenoid 17 to open the opening 11jlfP16, thereby preventing the attacker 14 from winning any prizes thereafter. The flag information in the RAM 52 displays the display on the rough display 22 and 23, turns on the start lamp 25, stops the generation of an electronic sound from the speaker 27, and stops the flashing of the central pocket lamp 26, and also displays the winning in the central pocket 15. Clear. Note that the speaker 27 may emit an electronic sound indicating an abnormality. Further, the count switch abnormality determination program shown in FIG. 7 may be separately executed during the delay processing.

Effects of the Invention A detection means for detecting a winning in a winning area where a game ball can be won when the opening/closing door is opened, and a second detection means disposed upstream of the means are provided, and a winning is achieved by the second detection means. Since the opening/closing door is closed when no winning is detected by the detection means within a predetermined time after the detection means is detected, the pachinko game machine loses its winning condition restriction function due to unauthorized modification of the detection means. In some cases, it is possible to reliably prevent excessive winning profits from being given to players, and it is possible to prevent unauthorized modification of pachinko gaming machines that have passed examination and certification based on the Entertainment Business Law.
