Field of the Invention The present invention relates to a hachinko gaming machine having a function of restricting the opening operation of a winning opening / closing door that opens and closes, which is a specific winning area, and in particular, an abnormality occurs in such a function. The present invention relates to a pachinko gaming machine that prevents unauthorized modification of a hachinko gaming machine that has passed the certification and certification based on the Customs and Business Law so that it becomes inoperable.

2. Description of the Related Art Conventionally, in addition to a normal winning area, first and second specific winning areas are provided, and when a game ball jumps into the first specific winning area, a second area is opened, and a winning opportunity is leapt. A pachinko gaming machine of a type that is designed to increase the player's interest is known as disclosed in Japanese Patent Laid-Open No. 59-40882.

Further, in such a type of gaming machine, in order to avoid agitating the player's aspiration, the maximum number of times the winning opening / closing door for opening / closing the second specific winning area is limited. It is known as Japanese Patent Laid-Open No. 59-115070.

However, even with such a gaming machine, if, for example, the game store side illegally remodels the detection switch that detects the number of times the winning opening / closing door is opened, the restriction function will be lost and the winning profit will be appropriate. Cannot be realized.

Separately from this, the first is arranged in association with the operating position of the prize ball payout mechanism and detects the operating state of the prize ball payout mechanism.
And a second detector arranged at a position where the safe sphere falling through the safe sphere passage can be detected, and the output of the first detector and the output of the second detector are provided. In response, based on the output state of the first detector and the output state of the second detector after a confusing time elapses, an unauthorized game for the prize ball payout mechanism from the outside of the pachinko gaming machine is detected. Japanese Unexamined Patent Application Publication No. Sho 54-
It is known as Japanese Patent No. 1141.

Problem to be Solved by the Invention An object of the present invention is to make a prize when a detection means for detecting a prize in a prize area opened and closed by a prize opening / closing door becomes abnormal and loses a prize condition limiting function. A pachinko game that can prevent game modification due to unauthorized modification of a pachinko gaming machine that has passed the verification and certification based on the Customs Business Law by closing the mouth opening and closing door and avoiding giving excessive prize money to the player The purpose is to provide a machine.

Means for Solving the Problems The pachinko gaming machine of the present invention is a winning area inside the winning opening opening / closing door, a driving means for opening / closing the winning opening opening / closing door, and a winning area placed in the winning area First to detect
Detecting means, a part of the special prize area in the prize area, a second detecting means arranged in the special prize area for detecting a prize in the special prize area, and the first detecting means. The driving means is controlled so that the winning opening opening / closing door is closed according to the detection result, and the driving means is operated so that the winning opening opening / closing door is opened / closed according to the detection result of the second detecting means. And a time measuring unit that operates at the time of winning detection by the second detecting unit, and the first measuring unit controls the time measuring unit to measure a predetermined time. When the winning is not detected by the detecting means, the control means controls the driving means so that the winning opening opening / closing door is closed.

When the winning opening opening / closing door is opened and thereafter the second detecting means detects a winning in the special winning area, the time measuring means operates from the time of this detection, and when the first detecting means operates normally, the time The first detecting means detects the winning in the winning area while the measuring means measures the predetermined time. The control means closes the winning opening / closing door when the number of winnings reaches a predetermined number according to the detection result of the first detecting means, and detects the winning according to the detection result of the second detecting means. Then, after closing the winning opening opening / closing door, the winning opening opening / closing door is opened, and when the number of times of opening / closing of the winning opening opening / closing door by the second detecting means reaches a predetermined number, the winning opening opening / closing door is closed.

On the other hand, if the winning in the special winning area is detected by the second detecting means, and the winning in the winning area by the first detecting means is not detected while the time measuring means measures the predetermined time, The operation of the first detection means is abnormal, and the control means closes the winning opening / closing door via the driving means, and prevents the subsequent winning of the winning area and the special winning area in the opening / closing door of the winning opening.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1 to FIG. 3, in addition to the normal winning holes 2 to 8 in the game board 1 of the pachinko gaming machine, the chuckers 11 to 13 and the second specific winning areas that form the first specific winning area are provided. The attackers 14 are provided at respective predetermined positions, and a central pocket 15 into which the game ball 100 can fly is provided at a substantially center inside the attacker 14 through an upper end opening to form a third specific winning area.

The start switch (GO switch) 18 (FIG. 4) consisting of three normally-open micro switches arranged in the prize ball guiding passage (not shown) provided on the back surface of the game board 1 is closed when the prize ball passes. The winning prize for the chuckers 11 to 13 is detected. Further, a count switch 19 composed of a normally closed proximity switch as a detecting means is arranged in the winning ball drop path defined by the peripheral wall of the central pocket 15 and the guide plate, and via the central pocket 15 or not. Attacker 1
When the game ball 100 wins within 4, the opening operation is performed to detect such a win. Further, a central pocket switch (V switch) 21 composed of a normally open type micro switch as the second detecting means is arranged at a position upstream of the count switch 19 with the actuating piece 21a facing the middle portion of the central pocket 15 and the pocket. The winning of 15 is detected.

Reference numerals 22 and 23 are upper and lower digital indicators arranged in the central portion of the game board 1, and reference numerals 24 and 25 are central pocket 1
5 and a central pocket lamp (V lamp) and a starting lamp (GO lamp) which blink or light when a prize is won to the chuckers 11 to 13, and a reference numeral 26 indicates an LED rotation operation described later provided on the front surface of the frame body of the gaming machine. It is a normally open push button type stop switch for stopping. A speaker 27 (FIG. 4) is attached to the back surface of the game board 1.

FIG. 4 shows an outline of the circuit configuration of the pachinko gaming machine. The above-mentioned various switches 18, 19, 21, and 26 are various winning display signals S1 of a level according to the open / closed state of these switches.
~ S3 and the LED rotation stop signal S4 are connected to the input port of the input / output circuit 40 via the switch input detection circuit 30. Central processing unit (C
The PU) 50 is connected to the input / output port of the input / output circuit 40 via a bus and also has a read-only memory (ROM) 51 and a CPU 5 for storing control programs and the like described later.
It is connected to a random access memory (RAM) 52 that stores various calculations and determination results executed at 0. The RAM 52 has a data storage area, and the CPU 5
According to the write command of 0, the prizes to the chuckers 11 to 13, the prizes to the pocket 15 and the L

Command data used for determination, control output data for driving various operating parts such as the solenoid 17, and the like are stored. Reference numerals 53 to 55 denote a clock circuit, a reset circuit and a power supply circuit, respectively. In addition, 61 to 66 are
These are various drive circuits that respectively drive corresponding ones of various operating parts such as the winning opening / closing door drive solenoid 17 according to the control output from the CPU 50 via the input / output circuit 40 as described later.

FIG. 5 shows a flow chart of a control program executed by the CPU 50, and the program is periodically executed according to a reset signal from the reset circuit 54. First, if the power is turned on in step 601, the process proceeds to the initialization process (step 602) to clear the switch flag, the winning number data, the command data, the control output data and the like in the RAM 52, and refresh the CPU 50. A counter (not shown) generates a random number, which is used as display data for the lower display 23. Next, the process proceeds to step 603, and if there is still no winning in the chuckers 11 to 13, the starting memory number indicating the number of winnings in the chucker is 0, and therefore all the answers of the determinations in steps 605 to 609 are negative, The winning opening opening / closing door driving solenoid 17, the lamps 24 and 25, and the speaker 27 are maintained in the deenergized state (step 610), and the present loop of this program ends.

On the other hand, when the game ball wins any of the chuckers 11 to 13, the start switch 18 is closed, so step 60
The determination result in 3 is affirmative, and 1 is added to the number of starting memories (step 604). Next, since the content of the command data is still 0, when it goes to step 611 through 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 number of starts (step 612), the software timer is set to the 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 is affirmative, and LE
The D rotation processing is performed (step 615), and the lower LED drive circuit 63 causes the respective display portions 23a to 2a of the lower display 23 to operate.
Display contents of 3c are updated one by one at different cycles,
It stops when the predetermined maximum LED rotation time elapses or when the push button stop switch 26 is operated, and at this time, the command data is updated to 2 indicating that the LED rotation is stopped. And L
During the ED rotation process, the starting lamp and the sound drive circuits 65, 6
The start lamp 25 is turned on according to each output of No. 6 and the rotating sound is output from the speaker 27.

In the next loop, LED rotation stop processing (step 616)
Is performed, the display contents of the display units 23a to 23c are sequentially stopped, and the command data is updated to 3 indicating that the LED determination is in progress.

Therefore, in the loop immediately after the completion of the LED rotation stop process, the process proceeds to the LED determination process (step 617), and the display content of the lower display 23 is determined based on the corresponding display data in the RAM 52. As a result of the determination, 3 displayed on the first to third display portions 23a to 23c of the display device 23
If the digital number of digits is not a doublet, the software timer is set to the first predetermined time, for example 0.4 seconds,
If it is an even-numbered doublet, in the second predetermined time, for example, 6 seconds,
If it is an odd-numbered doublet (big hit prize), it is set to a third predetermined time, for example, 20 seconds. Also, the command data is updated to 4 indicating that the attacker is being opened.

In the next loop, the attacker opening process is executed (step 618), and the solenoid driving circuit 61 receives the solenoid 17
Is activated and the prize opening / closing door 16 is displayed on the attacker 14
Open for the set time according to the combination of the display numbers of 3. However, at the time of a big hit prize, the prize opening / closing door 16 is closed when the number of wins to the attacker 14 reaches 10 even if the third predetermined time has not elapsed.

Further, during opening of the attacker, the starter lamp 25 is turned on and the speaker 27 outputs an opening sound. Further, when the central pocket 15 is won, the central pocket lamp 26 is blinked, and the number of such winnings is a predetermined number of times, for example, 1
R is the flag information that displays the prize unless it has reached 0 times
Store in AM52.

When the first, second or third predetermined time elapses after the attacker is opened, the command data indicates that the delay process is in progress.
Is updated, and the delay process is executed in the next loop (step 619). That is, if it is determined based on the flag information that there is no winning in the central pocket 15, the process proceeds to the above-described step 610, and if there is such winning, the attacker 14 is opened again. Therefore, the attacker 14 continuously receives 10 points on condition that the central pocket 15 is won.
It has been opened for many times.

Then, during the opening of the attacker and the delay process, the display 2
Number of consecutive winnings in the central pocket 15 and attacker 1 in 3
The number of winnings to the attacker 14 during each opening operation of No. 4 is displayed.

As described above, in the pachinko gaming machine of the present embodiment, when the player 10 wins in the attacker 10 times so as not to arouse the player's aspiration, the winning opening / closing door 16 is closed to prevent further winning. However, for example, between the contacts of the normally closed type count switch 19 or the lead wires 19a and 19b.
By short-circuiting (FIG. 4), the switch 19 does not always detect the winning regardless of whether the attacker 14 actually wins. Therefore, for example, it is conceivable to illegally modify the count switch 19 so as to give an excessive winning profit to the player at the game shop side. In this embodiment, in addition to the control programs (not shown) for the above-mentioned various operations, The abnormality determination program shown in FIG. 6 is executed to prevent this kind of unauthorized modification.

That is, the CPU 50 determines whether the short-circuit timer as the time measuring means has timed up during the attacker opening process (step 618 in FIG. 5) (step 701 in FIG. 6). The timer is composed of software, and times up when the stored value reaches a value corresponding to a predetermined time, for example 1.4 seconds. If the short-circuit timer has not timed up yet in step 701, the process proceeds to step 702 and it is determined whether the stored value of the timer is "0". Since the short circuit timer is reset when the power of the pachinko gaming machine is turned on, and the stored value is "0" at this place, step 70
5, the process determines whether or not the V switch 21 has been turned on, that is, whether or not there is a prize to the attacker 14 via the central pocket 15 based on the output level of the V switch 21.
If the V switch 21 is not turned on, the stored value of the short circuit timer is transferred to the RAM 52 and stored therein (step 70).
8) The program ends.

After that, the program is executed through the above-described path until the V switch 21 is turned on, and when the V 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 the winning is still made. If not, the timer storage value is set to "1" in step 707, and this program is terminated via step 708. In the next loop, since the stored value is not "0", "1" is added to the stored value, and it is determined whether the count switch 19 is turned on or not based on the output level (step 704). As described above, since the V switch 21 faces the middle portion of the central pocket 15 and is arranged upstream of the count switch 19, the count switch 19 normally operates when the attacker 14 wins through the central pocket 15. If so, the count switch 19 is turned on within the predetermined time (1.4 seconds) at the latest after the V switch 21 is turned on, usually about 0.4 seconds later (FIG. 7). Therefore, if the count switch 19 is normal, the switch 19 is turned on and the short-circuit timer is reset before the short-circuit timer times out (step 709), and the next abnormality determination is started when the V-switch 21 is next turned on. Until the time of execution, the pachinko gaming machine is kept in the used state.

On the other hand, if the count switch 19 is not turned on after the V switch 21 is turned on, the stored value of the short-circuit timer is updated each time the program is executed, and the stored value is updated for a predetermined time, for example, 1.4.
When the second has elapsed, it is determined in step 701 that the timer has expired, and the process proceeds to step 710 to execute the abnormal condition process.

The abnormal time process is executed by the CPU 50 by the solenoid drive circuit 6
The control output to the solenoid 17 via 1 is extinguished to close the winning opening opening / closing door 16 and prevent the subsequent winning of the attacker 14 and the central pocket 15. Further display 2
RA for displaying the numbers 2 and 23, turning on the start lamp 25, stopping the generation of electronic sound from the speaker 27, and blinking the central lamp 26, and displaying the winning in the central pocket 15.
The flag information in M52 is cleared. The speaker 2
An electronic sound indicating an abnormal condition may be emitted from 7. Further, the count switch abnormality determination program of FIG. 6 may be separately executed during the delay process.
