Description

Description: TECHNICAL FIELD The present invention relates to a pachinko machine, and more particularly to a pachinko machine capable of preventing fraudulent acts performed by a player or a pachinko parlor.

[Prior Art and Challenges] Since a pachinko game involves gains such as prizes, various frauds have been conventionally performed by the player, and all these frauds aim to receive extra payout of prize balls.

For example, a pachinko machine detects whether a safe ball has entered the winning opening during the game with a safe ball sensor, and when the safe ball enters, the ball cutting device is operated to place the prize ball on the prize ball plate. It is supposed to be paid out. However, a player may cause the safe ball sensor to malfunction and pay out the prize ball even though the safe ball does not enter the winning opening.

In addition, the usual pachinko machine collects the prize balls in the prize ball tank into the ball collecting section as necessary, and therefore, when the ball removing switch in the pachinko machine is operated, the ball cutting device is continuously operated. Along with paying out the prize balls, the passage is switched by the switching lever to collect the prize balls in the ball collecting section. However, the player uses this mechanism to insert a piano wire or the like through the gap in the front frame and operates the ball-removing switch to continuously operate the ball-slicing device, and further interferes with the operation of the switching lever to win the prize. Sometimes the ball is thrown out to the prize ball plate.

Although the above-mentioned misconduct is caused by the player, the pachinko parlor side may also engage in misconduct, and as a typical example, the number of prize balls paid out regulated by law is arbitrarily changed. There is cheating. For example, in a pachinko machine with a sensor installed in one of the prize holes, and when a safe ball enters the prize hole, the number of prize balls different from the normal number of prize balls is paid out. In some cases, the signal may be cut off so that only one type of prize ball is always paid out.

A first object of the present invention is to provide a pachinko machine capable of preventing an illegal act in which a player malfunctions a safe ball sensor to pay out a prize ball.

A second object of the present invention is to provide a pachinko machine capable of preventing an illegal act in which a player operates a ball removing switch in the pachinko machine to pay out a prize ball.

A third object of the present invention is to provide a pachinko machine capable of preventing fraudulent behavior in which a pachinko parlor arbitrarily changes the number of prize balls paid out.

[Means for Solving the Problem] The first invention is to send a safe ball, which is detected by a sensor while the electric ball is released by the electric detention releasing means, into the safe ball entering the winning opening and exiting from the safe ball passage. The present invention relates to a safe ball detection condition and a prize ball payout condition, and a ball cutting device that pays out a predetermined number of prize balls by performing a payout operation once per unit against the detection condition of each safe ball of the sensor. A CPU (central processing unit) including a payout control commanding means for input / output control is provided, and the electric detention releasing means temporarily becomes safe after the completion of the prize ball payout operation performed during the safe ball detection of the sensor. In response to the displacement operation to the ball release side, the sensor is returned to the ball-free detection state when the safe ball is released and dropped, and in response to this, the electric detention release means is actuated to return to the original safe ball detention side. Set to When the sensor changes to the ball non-detection state during the prize ball payout operation, or the safe ball release side operation of the electric retention release means after the prize ball payout operation is completed, the sensor has a ball for a set time or more. The gist is that, in the detection state, the fraud prevention means of the CPU is set to judge the malfunction caused by the manipulation of the sensor and immediately stop or stop the prize-ball payout operation.

A second aspect of the invention is a ball cutting device that pays out the prize balls sent from the prize ball storing and sending unit side in a predetermined number unit according to the safe ball detection condition, and the prize balls discharged from the ball cutting device. A dispensing passage for guiding to the dish side, a ball removing passage for guiding to the ball collecting portion side outside the frame, a ball removing electric means for switching and operating switching means for individually opening and closing each passage, and a front side of the pachinko machine. And a ball-removing switch for driving the ball-removing electric means, and a drive command for the ball-removing electric means based on an operation signal of the ball-removing switch and a ball-releasing command for the ball-slicing device. With a CPU (central processing unit) including a ball removal control command means, in the power-on state of the pachinko machine, the ball removal sent from the CPU side in response to the first input of the operation signal of the ball removal switch. Based on control command The ball-removing electric means switches the switching means to the ball-removing side, and the ball-cutting device is set so as to be switched and held in the ball-removing release state. The point is that the settings are made so that input invalidation processing is performed.

A third invention is a classification detection sensor that detects a safe ball that has entered a specific winning opening of a game board, a safe ball sensor that performs detection processing for each safe ball that has entered a winning opening, and each safe ball. The ball cutting device that divides and pays out the number of first and second prize balls preset according to the above, and whether or not the detection condition signal of the classification detection sensor is input based on when the safe ball is detected by the safe ball sensor. And a CPU (central processing unit) including a payout control command means for issuing a payout command according to the presence / absence of the input, and as a classification detection condition of the classification detection sensor, the signal conversion circuit unit side does not have a sphere. The high-level signal when the sphere is present and the low-level signal when the ball is present are set to enable division input to the CPU through the signal line, and this low-level signal is input to the CPU only for the set effective detection time. Enable No time or more input time determination signal Anomalies in the subject matter that has been adapted to disable the stop processing the operation the prize ball payout by.

[Action]

In the first aspect of the present invention, when the sensor changes to the no-ball detection state during the prize ball payout operation performed under the safe ball detection input condition by the safe ball sensor, the electric detention releasing means after the prize ball payout operation is completed. When the sensor is in the detection state with the ball for the set time or longer even though the ball has been operated toward the safe ball release side, the CPU judges the sensor malfunction and immediately stops or stops the prize ball payout operation. Let
As a result, even if a player who attempts to illegally acquire a prize ball illegally operates the sensor, the illegal acquisition of a prize ball without a safe ball is prevented based on the prize ball payout stop process.

In the second aspect of the invention, regarding the ball removal operation in the power-on state of the pachinko machine, the CPU allows the operation signal from the ball removal switch to be input only once (once).
All the operation signals after the first time are invalidated. This is the first time that a player or the like who attempts to illegally obtain a prize ball illegally operates the operation switch while holding the switching means that can be switched by the electric means in the original position on the payout side. Only in this case, it is possible to minimize the damage that only the prize balls remaining in the plane are illegally discharged to the bowl side, and it is impossible to remove the balls by the second and subsequent illegal operations after the new prize balls are replenished. To be done.

In the third aspect of the invention, the detection condition from the classification detection sensor is divided into a high level signal without a sphere and a low level signal with a sphere, and the low level signal is input to the CPU. Only the detection time can be input, and signals other than this time are processed so as not to be input to determine the signal abnormality, and the prize ball payout operation is disabled. As a result, in a pachinko machine used for playing games, if the signal line related to the classification detection sensor is cut or short-circuited in an attempt to illegally change the originally set number of prize balls, the CPU always keeps a low level. In response to the signal being left input, the award ball payout operation is immediately disabled and stopped, and the subsequent award ball payout is prohibited and the unauthorized payout of the changed number is prevented.

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

FIG. 2 is a rear view schematically showing the whole of the pachinko machine, a set plate 2 made of synthetic resin is attached to the back side of the front frame 1, and a prize ball tank 3 is provided above the set plate 2. Has been. One end of the gutter 4 is connected to the prize ball tank 3, and the other end of the gutter 4 is connected to a ball supply path 5 extending vertically. The downstream side of the ball supply path 5 branches into a payout path 6 and a ball removal path 7, and the payout path 6 communicates with a prize ball plate (not shown) provided on the front surface of the front frame 1 through a supply hole 8, The extraction passage 7 communicates with a ball collection unit (not shown).

The prize balls that rectify the inside of the gutter 4 in two rows are sent to the ball supply path 5 side in one row by the prize ball aligning and sending tool 50 (see FIG. 2).

1 and 3 are front views showing the details of the ball supply path 5, and a ball cutting device 9 for paying out a predetermined number of prize balls to the prize ball plate is installed at one end of the ball supply path 5. ing. A large number of engaging recesses 10a are formed on the outer periphery of the sprocket 10 of the ball cutting device 9, and one side of the sprocket 10 projects into the ball supply path 5 through a through hole 5a. A ball cutting solenoid 11 of a ball cutting device 9 is installed near the sprocket 10, and a movable iron piece 12 for a stopper for the sprocket 10 is rotatably attached to a bracket 11a of the solenoid 11.

When the ball cutting solenoid 11 is not excited, the movable iron piece 12 is urged by the tension spring 13 as shown in FIG.
The leading end of the sprocket is hooked in the engaging recess 10a of the sprocket 10 to make the sprocket 10 unrotatable. As a result, the prize balls in the ball supply path 5 are prevented from falling by the sprockets 10. When the ball cutting solenoid 11 is excited, the third
As shown in the figure, the movable iron piece 12 is the core 11b of the solenoid 11.
And the sprocket 10 is unlocked and becomes rotatable. As a result, the prize balls in the ball supply path 5 drop as the sprocket 10 rotates. Since the ball cutting solenoid 11 is in a non-excited state and restrains the sprocket 10 in a normal state, the prize ball is prevented from falling.

Upper and lower prize ball sensors 14 and 15 are provided vertically at positions near the sprocket 10 in the ball supply path 5. Both prize ball sensors 14 and 15 output an ON signal (no ball signal) because the light from the light emitting unit is received by the light receiving unit when there is no prize ball at each installation location, and when there is a prize ball. Since the light from the light emitting unit is blocked by the prize ball and does not reach the light receiving unit, an off signal (sphere presence signal) is output. The upper prize ball sensor 14 is connected to the sprocket 10
It is designed to detect the lowest prize ball that is prevented from falling by the lower prize ball sensor 15
It is designed to detect prize balls that fall with the rotation of 10.

A switching lever 16 as a switching means is rotatably attached to a location where the ball supply path 5 branches into a payout path 6 and a ball removal path 7. The switching lever 16 is driven by the ball-sucking solenoid 17, and switches between two positions, that is, a position for closing the ball-sending passage 7 side shown in FIG. 1 and a position for closing the dispensing passage 6 side shown in FIG. It is supposed to do. still,
In the normal state, the switching lever 16 is in a position to close the ball removing passage 7 side, and at this time, the ball removing solenoid 17 is in a non-excited state. Therefore, the prize balls paid out from the ball cutting device 9 are supplied to the prize ball dish through the payout passage 6.

On the other hand, as shown in FIG. 2, the game board 1a of the front frame 1 is provided with a specific winning opening 19a and a large number of winning openings 19b. A board surface sensor 1 as a means for detecting a prize category is provided at the specific winning opening 19a.
8 is provided to detect the entry of a safe ball into the specific winning opening 19b. In addition, the safe balls that have entered the respective winning openings 19a, 19b are designed to flow into the safe ball passage 20, and one safe ball is detected on one side of this safe ball passage 20 and released. A safe ball sending device 21 is installed.

4 and 5 are front views showing the details of the safe sphere sending device 21. A bracket 22a is fixed to a safe ball solenoid 22 as a movement preventing means of the safe ball sending device 21, and a movable iron piece 23 is pivotally attached to the bracket 22a. A semicircular turning piece 24 is rotatably mounted above the safe ball solenoid 22, and a weight 25 is fixed to the outer circumference of the turning piece 24 so that the turning piece 24 is always clockwise. I am biased. As a result, the operation corner portion 24a of the lower portion of the rotating piece 24 is always in contact with the tip of the movable iron piece 23.

When the safe ball solenoid 22 is not excited,
As shown in FIG. 4, the movable iron piece is biased by the tension spring 26.
The tip of 23 projects into the safe ball passage 20 through the through hole 20a, and the blocking corner portion 24b of the turning piece 24 withdraws from the safe ball passage 20. As a result, the safe ball in the safe ball passage 20 is prevented from falling by the tip of the movable iron piece 23.
When the safe ball solenoid 22 is excited from this state, the movable iron 23 moves the core of the solenoid 22 as shown in FIG.
It is sucked by 22b, and the tip thereof is withdrawn from the safe ball passage 20. At the same time, the turning piece 24 is pushed by the tip of the movable iron piece 23.
Rotates counterclockwise, and the blocking corner 24b of the movable iron piece 23
One safe ball is projected above the projecting portion of the above into the safe ball passage 20 through the through hole 20a.

As a result, the safe sphere located upstream of the blocking corner 24b is prevented from falling, and only one safe sphere located between the blocking corner 24b and the tip of the movable iron piece 23 falls to drop the sphere. It is collected in the collection unit. When the safe ball solenoid 22 is demagnetized, the next safe ball released by the return of the turning piece 24 for the second stopper to its original state descends as shown in FIG. Movable iron piece 23 for 1 stopper
Is stopped and prevented from falling.

A safe ball sensor 27 is provided between the movable iron piece 23 and the blocking corner portion 24b, and the sensor 27 outputs an ON signal (no ball signal) when there is no safe ball in the detection opening, and the movable ball sensor 27 moves. When there is a safe ball stopped by the iron piece 23, an off signal (ball presence signal) is output.

A cover (not shown) is detachably attached to the back surface of the front frame 1 so as to close the side surfaces of the ball supply path 5, the payout passage 6, the ball removal passage 7, and the safe ball passage 20. Further, as shown in FIG. 2, the ball removing solenoid 17 is provided on the right side of the back surface of the front frame 1 in order to collect all the prize balls in the prize ball tank 3 in the ball collecting section when the pachinko parlor is closed. A ball-removing switch 28 for driving input is provided. Further, a control box 29 is installed on the lower side of the back surface of the front frame 1, and the box 29 is provided with a reset switch 30 for reactivating the pachinko machine once the dispensing operation is stopped.

On the other hand, as shown in FIG. 2, first and second display lamps 31, 32 are provided on the front surface of the front frame 1, and both display lamps 31, 32 are provided.
The numeral 32 is adapted to be lit or blinked at the time of paying out a prize ball, which will be described later, when a ball is removed, when each sensor or solenoid is out of order, or when a player makes an illegal act.

Next, the electrical configuration of the pachinko machine of this embodiment will be described with reference to FIG.

A central processing unit 35 (hereinafter referred to as a CPU) and drive circuits 36 to 40 are housed inside the control box (electronic control circuit device for discharging prize balls) 29. Also, CPU35
A game board 33 (an electronic control circuit device for games) is connected to the input side of, and a board surface sensor 18 is connected to the game board 33. In addition, the input side of the CPU35 has 1st to 4th
The prize ball number setting devices 42 to 45, the safe ball sensor 27, the upper and lower prize ball sensors 14 and 15, the ball removing switch 28, and the reset switch 30 are connected. On the output side of the CPU 35, the ball cutting solenoid 11, the ball removing solenoid 17, the safe ball solenoid 22, the first and second display lamps 31, 32 are provided.
Are connected via drive circuits 36 to 40, respectively. In the pachinko machine of this embodiment, the CPU 35 constitutes fraud prevention means, payout control means, ball removal control means, and ball removal prevention means. Although the game board 33 is installed outside the control box 29 in the pachinko machine of this embodiment, it may be installed inside the control box 29.

The first to fourth award ball number setting devices 42 to 45 are the number of award balls paid out by the ball cutting device 9 (basically a small number) corresponding to the safe ball classification detection condition set in the game content. And a large number of two) are set in advance, and CPU3
Two kinds of level signals are selectively input to the 5 input side.

The configurations related to the respective prize ball number setting devices 42 to 45, the prize ball number selection setting conditions, etc. are the same as the technical contents specified in Japanese Patent Application No. 1-249974 filed at the same time as the present application. .

Further, the CPU 35 has a random access memory (RAM) 46 and a read only memory (ROM) 47 built therein. ROM
In 47, the first and second set award balls are the award ball number setting devices.
A plurality of sets are stored according to combinations of input states of 42 to 45. Further, various programs are stored in the ROM 47, and the CPU 35 executes various processes in accordance with these programs. The RAM 46 is adapted to temporarily store the data of the processing performed by the CPU 35.

FIG. 7 is a schematic diagram showing a connection state of the game board 33 and the board surface sensor 18 to the CPU 35, and FIG. 8 is an explanatory view showing a detection signal of the board surface sensor 18 inputted from the game board 33 to the CPU 35. As shown in these figures, the board surface sensor 18 is connected to the game board 33 by two signal lines 18a. Similarly, the game board 33 is connected to the CPU 35 by two signal lines 3a.
It is connected by 3a and 33b. The signal line 33b is grounded.

Under this condition, as a detection condition of the board surface sensor 18, before the safe sphere is detected, a high-level (5V) detection signal is input to the CPU 35 from the signal conversion circuit side of the game board 33. That is, the potential of the other signal line 33a is different from that of the grounded signal line 33b.
It becomes 5V. In addition, when the safe ball is detected, the low level (0V) detection signal is sent from the signal conversion circuit side of the game board 33 to the CP.
Input to U35. That is, the potential of the other signal line 33a becomes 0V with respect to the grounded signal line 33b. Then, the CPU 35 determines whether a safe ball has entered the specific winning opening 19a based on the detection signal.

Next, the operation of the pachinko machine configured as described above will be explained below.
It will be described with reference to FIGS.

9 and 10 show a flowchart of the "main routine". When the power of the pachinko machine is turned on, the CPU 35 clears the RAM 46 in step 1, performs the port initial in step 2, and executes the timer initial in step 3. .
Further, in step 4, the CPU 35 inputs a signal from the first to fourth award ball number setting devices 42 to 45 and sets the first and second set award ball numbers corresponding to the combination of the signal levels to the RO.
Elected from M47. Then, in the subsequent pachinko game, the set number of prize balls is paid out. For convenience of explanation, it is assumed that "7" is selected as the first set prize ball number and "13" is selected as the second set prize ball number.

Next, the CPU 35 sets the number of set prize balls selected in step 5 to the above-mentioned R.
At the same time as writing to AM46, the states of the sensors 14, 15, 27 and switches 28, 30 are also written to RAM46. At the same time, in step 5, the CPU 35 reads the state of the board surface sensor 18 in accordance with the "ball entrance determination routine".

FIG. 11 shows a flow chart of the "ball entry determination routine". First, the CPU 35 reads the detection signal from the game board 33 in step 6, and determines in step 7 whether the signal is low level (0V) or not. To do. If it is at the low level, the CPU 35 determines in step 8 whether the state continues for 10 ms or more. When the low level does not continue for 10 ms or more, the CPU 35 invalidates the signal because the player has made an illegal operation such as the board sensor 18 malfunctioning and returns to the step 7, and when the low level continues for 10 ms or more, the step 35 Low-level duration of 128m
Determine if it is less than or equal to s.

If the low-level duration is 128 ms or less, it is determined that the safe ball has entered the specific winning opening 19a without any fraud, and the CPU 35 returns to the "main routine" and returns to step 1
At 1, the value "1" is added to the prize ball number selection counter N built in the ROM 47, and the process proceeds to step 12. In this way, the count value of the prize ball number selection counter N is added every time the safe ball enters the specific winning opening 19a. If the duration of the low level is 128 ms or more in step 9, it is assumed that the player has caused the board sensor 18 to malfunction and the safe ball has not actually entered the specific winning opening 19a as in step 8. In step 10, the CPU 35 blinks the first display lamp 31 at 4 Hz via the drive circuit 39 to notify the administrator of this situation, and also suspends the load of each solenoid and stops the pachinko game.

It should be noted that, in the text, "stop of pachinko game" specifically means stop or stop (inability) of payout operation of prize balls.

Therefore, as shown by the solid line in FIG. 8, when the detection signal from the game board 33 is at a low level, it is 10 ms or more and 128 m or more.
Only when it continues for s or less, "1" is added to the prize ball number selection counter as the safe ball has entered the specific winning opening 19a.

As described above, the reason why the low-level duration (safe ball detection time of the board sensor 18) is limited in steps 8 and 9 is not only to prevent the board sensor 18 from malfunctioning due to fraud, as described above. The game board 33 and CP
This is also for coping with disconnection or short circuit of the signal lines 33a and 33b connecting to the U35. That is, as described below,
The number of prize balls that are different from the other safe balls is paid out to the safe balls that enter the ball 19a and are detected by the board surface sensor 18, but the number of these prize balls is legal. It is not allowed for pachinko parlors to change the number of prize balls without permission. However, some users ignore the regulation and change the number of prize balls. As one of the means, the two signal lines 33a and 33b are cut or short-circuited to output the output signal of the board surface sensor 18. May interfere.

When both the signal lines 33a and 33b are disconnected, the signal line 33a on the non-grounded side is not energized, and its potential becomes 0V. When both signal lines 33a and 33b are short-circuited to each other, the non-grounded signal line 33a has the same potential as the grounded signal line 33b, that is, 0V. Therefore, in any case, the signal input to the CPU 35 always remains at the low level regardless of whether or not the board surface sensor 18 detects the safe sphere. On the other hand, if the low-level signal continues for a predetermined time or longer in step 9, the prize ball payout operation is immediately disabled in step 10, and even if the safe ball sensor 27 detects the safe ball thereafter, all prize ball payout is performed. Can not be executed. That is, with respect to the above-mentioned fraudulent attempts, a strict prohibition process is performed due to the inability to pay out the prize balls, and this kind of fraudulent operation is not accepted at all and can be prevented in advance.

In order to restart the payout operation of the prize balls which has been disabled in step 10, the signal lines 33a and 33b described above are restored to the original normal connection state. Under this condition, when the power is turned on again or the reset switch 30 is operated, the CPU 35 is returned to the initial state and the processes from step 1 can be executed.

Next, based on the detection signal read in step 5 in step 12, the CPU 35 determines whether or not a signal with a ball is input from the lower prize ball sensor 15 twice or more (whether or not two or more prize balls are detected). ) Is determined. When the ball presence signal is input from the lower prize ball sensor 15 more than once, it is determined that the prize ball has leaked from the sprocket 10 of the ball cutting device 9, and the CPU 35 proceeds to step 13 to set the ball removing solenoid 17 via the drive circuit 37. Excite,
The switching lever 16 is switched to open the ball removing passage 7 side and close the payout passage 6 side. As a result, the prize balls leaked from the sprocket 10 are guided to the side of the ball removing passage 7 and the player is prevented from being improperly paid out. At the same time, the CPU 35 notifies the manager of this situation by blinking the second display lamp 32 at 4 Hz via the drive circuit 40 in step 13 and stops the pachinko game by stopping the load of each solenoid. To do.

When the prize ball leaks from the sprocket 10 in this way, it can be inferred that some abnormality has occurred in the ball cutting device 9. Therefore, when such a problem occurs, it is possible to prevent the pachinko game from being stopped and the prize balls being paid out to the player as described above.

On the other hand, when the lower prize ball sensor 15 does not detect two or more prize balls in step 12, the CPU 35 determines that the ball cutting device 9 is normal, and in step 14, the lower prize ball sensor 15 outputs a signal indicating that there is a ball for 10 seconds or more. It is determined whether or not is input. Under the condition that the sensor 15 should not continue to detect the falling prize balls for more than 10 seconds under the condition that the discharge of the prize balls is stopped one by one due to the normal operation of the ball cutting device 9,
When the signal with a ball is input for 10 seconds or more, the CPU 35 determines that the sensor has failed. In this case, CPU35
Then, the second display lamp 32 is blinked at 4 Hz via the drive circuit 40 to notify the manager of this situation, and the loads of the solenoids are stopped to stop the pachinko game.

On the other hand, if the lower prize ball sensor 15 does not output a ball presence signal for 10 seconds or more in step 14, the CPU 35 determines that the lower prize ball sensor 15
Is determined to be normal, and it is determined in step 16 whether the sphere presence signal is input from the safe sphere sensor 27. Then, when the ball presence signal is not input, the CPU 35 determines that the player has not started the pachinko game, or that the safe ball has not entered any of the winning openings 19a, 19b even if the game has started. Move to 17. Then, in step 17, the CPU 35 determines whether or not the ball removing switch 28 has been operated for 0.5 s or more, and if it has not been operated, the process returns to step 4.

On the other hand, if the ball removal switch 28 has been operated for 0.5 s or more in step 17, is the CPU 35 operating this ball removal switch 28 in step 18 after turning on the power of the pachinko machine? If it is the first switch operation, a ball removal process to be described later is executed in step 19. If the ball removal switch 28 has been operated before, the CPU 35 invalidates the detection of the ball removal switch 28 and returns to step 4. In this case, the ball removal process of step 19 is not executed no matter how many times the ball removal switch 28 is operated in step 17. Therefore, the ball removing process can be executed only once after the power of the pachinko machine is turned on, and when performing the second ball removal, it is necessary to once turn on the power of the pachinko machine again or operate the reset switch 30. .

The ball removal processing in step 19 described above is performed according to the "ball removal routine" shown in FIG. First, in step 20, the CPU 35 alternately blinks the first and second display lamps 31 and 32 at 4 Hz via the drive circuits 39 and 40 to notify the administrator that the ball removal processing will be executed. Next, in step 21, the CPU 35 excites the ball removing solenoid 17 to switch the switching lever 16 to close the payout passage 6 side and open the ball removing passage 7 side. Further, the CPU 35 executes step 22.
0 until the switching operation of the switching lever 16 is completed.
After waiting for 2 seconds, the ball cutting solenoid 11 is excited in step 23 to make the sprocket 10 rotatable. As a result, the prize balls stored in the prize ball tank 3 are sequentially collected in the ball collecting section through the ball removing passage 7.

Further, the CPU 35 waits for 45 seconds in step 24 (after all the prize balls in the prize ball tank 3 have been collected in the ball collecting portion), and then in step 25, the ball cutting solenoid 11 is demagnetized to make the sprocket 10 unrotatable. Next, the CPU 35 waits for 0.2 s until the operation of the ball cutting solenoid 11 is completely completed in step 26, then demagnetizes the ball removing solenoid 17 in step 27 to switch the switching lever 16 and open the dispensing passage 6 side. At the same time, the ball removal passage 7 side is closed to return to the initial state. Then, the CPU 35 turns off both display lamps 31 and 32 which are alternately blinking in step 28.

In this way, by operating the ball removing switch 28, the prize ball tank 3
The prize balls are collected by the ball collecting unit. Normally, this operation is performed by the manager of the pachinko parlor when the pachinko parlor is closed, but the player uses this mechanism to insert a piano wire or the like through the gap in the front frame 1 and operate the ball pulling switch 28 to operate the sprocket. In some cases, 10 is made rotatable, and furthermore, the operation of the switching lever 16 is disturbed and the prize ball is paid out to the prize ball plate. At this time, the first wrongdoing is
Even if the operation of the ball removal switch 28 is enabled only in the first time in 18, the second and subsequent fraudulent acts are prevented by the processing in step 18. In addition, the ball removal switch by the administrator
Since the operation of 28 is normally performed only once when the store is closed, there is no risk of trouble even if the number of times is limited in this way.

On the other hand, when a ball presence signal is input from the safe ball sensor 27 in step 16, the CPU 35 assumes that the player has started a pachinko game and a safe ball has entered one of the winning openings 19a, 19b, and will be described below. The payout process for the safe ball is executed. First, in step 29, the CPU 35 determines whether or not the ball presence signal from the safe sphere sensor 27 has continued for 50 ms or more. If it does not continue, the CPU 35 determines that the signal is invalid and returns to step 4 above. When the ball presence signal continues for 50 ms or more, the CPU 35 sets the bound counter C, which will be described later, to "0" in step 30.

Next, in step 31, the CPU 35 selects the prize ball number selection counter N.
It is determined whether or not the count value of "0" is "0", and if the count value is not "0", "13" set as the second set prize ball number in step 32 is provided in the payout counter incorporated in the RAM 46. Write to M. Further, the CPU 35 subtracts "1" from the prize ball number selection counter N in step 33, and
At 34, the second display lamp 32 is turned on and the process proceeds to step 37.

On the other hand, when the count value of the prize ball number selection counter N is “0” in step 31, the CPU 35 writes “7” set as the first set prize ball number in step 35 to the payout counter M. Further, the CPU 35 turns on the first display lamp 31 in step 36 and shifts to step 37.

Therefore, when the safe ball enters the specific winning opening 19a, the second set prize ball number "13" is written in the payout counter M, and when the safe ball enters the other winning opening 19b, the payout counter M is displayed. The first set prize ball number “7” is written.

Further, in step 37, the CPU 35 determines whether or not a ball presence signal is input from the upper prize ball sensor 14 (whether or not a prize ball to be paid out to the player is secured), and inputs the ball presence signal. If so, the ball-cutting solenoid flag F is set to 0 in step 38, and the ball-cutting solenoid timer is cleared and started in step 39. In addition, this ball-cutting solenoid timer is designed to time up in 128 ms.

Next, in step 40, the CPU 35 determines whether or not the ball-cutting solenoid timer has timed out. If not, in step 41, the ball-cutting solenoid flag F is determined.
= 0 is determined. Since this solenoid flag is set to F = 0 in step 38, the CPU 35 determines in step 4
After shifting to 2, the sphere cutting solenoid 11 is excited to rotate the sprocket 10 freely.

Then, when the CPU 35 inputs the no-sphere signal (ON signal) from the upper prize ball sensor 14 in step 43, the prize ball located at the upper prize ball sensor 14 falls with the rotation of the sprocket 10, and The upper prize ball sensor 14 is turned on (no ball is present) due to the gap between the prize ball and the prize ball above the prize ball, and thus it is determined that the prize ball has normally dropped. Then, the CPU 35 proceeds to step 45 and moves the ball cutting solenoid 11
Degauss. Therefore, with the above operation, only one prize ball is paid out to the prize ball plate.

If the no-sphere signal is not input from the upper prize ball sensor 14 in step 43, the CPU 35 proceeds to step 44. Then, when a ball presence signal (OFF signal) is input from the lower prize ball sensor 15 in this step 44, the CPU 35 causes the prize ball located on the upper sensor 14 to move to the lower prize ball sensor 15 as the sprocket 10 rotates. After passing the position, it is determined that the lower prize ball sensor 15 is turned off by this prize ball, that is, the prize ball is normally dropped. Then, the CPU 35 proceeds to step 45 to demagnetize the ball cutting solenoid 11. Therefore, even in this case, only one prize ball is paid out.

Further, if the no-sphere signal is not input from the upper prize ball sensor 14 in step 43, and the ball presence signal is not input from the lower prize ball sensor 15 in step 44, the CPU 35 indicates that the prize ball has fallen normally. If not, the process returns to step 40.

On the other hand, if the CPU 35 determines in step 40 that the ball-cutting solenoid timer has timed out (128 ms has elapsed), it clears the solenoid timer in step 46 and inverts the ball-cutting solenoid flag in step 47 (in this case, flag F = 0 is inverted to F = 1), and the process proceeds to step 41. The CPU 35 proceeds to step 48 because the ball cutting solenoid flag is F = 1 in step 41. Then, the CPU 35 degausses the ball cutting solenoid 11 in step 48, and then determines in step 43 and step 44 whether or not the prize ball has fallen normally. When the CPU 35 determines that the prize ball has fallen normally, the CPU 35 proceeds to step 45 and continues the demagnetization of the ball cutting solenoid 11. If the CPU 35 determines that it has not fallen normally, the CPU 35 returns to step 40 and executes the processing from step 40 to step 44 again.

Therefore, the CPU 35 inverts the flag F in step 47 (every 128 ms) every time the ball-cutting solenoid timer times out in step 40, and executes either step 42 or step 48 accordingly. Then, when step 42 is executed, the ball cutting solenoid 11 is excited, and when step 48 is executed, the ball cutting solenoid 11 is demagnetized. As a result, the ball cutting solenoid 11 repeats excitation and demagnetization every 128 ms.

Therefore, for example, when foreign matter such as polylon for pachinko ball polishing (trademark) or the like prevents the falling of the prize ball, the ball cutting solenoid 11 intermittently operates every 128 ms to apply vibration to the sprocket 10, It is possible to drop the foreign matter and drop the prize ball normally.

Next, after the excitation of the ball-cutting solenoid 11 is stopped in step 44, the CPU 35 determines in step 49 whether a ball presence signal is input from the lower prize ball sensor 15 within 100 ms. Then, when the ball presence signal is not input, the CPU 35 determines that the prize ball does not drop normally from the sprocket 10.
At "50", "1" is added to the bound counter C which has been "0" until now, and at step 51 it is judged whether the count value is 3 or more.

When the count value of the bound counter C is 3 or more,
CP35 shifts to the above step 15, and the second indicator lamp
32 is blinked at 4 Hz to notify the administrator of this situation, and the loads of the solenoids are stopped to stop the pachinko game. If the count value of the bound counter C is less than 3, the CPU 35 returns to step 37,
The prize ball payout process from step 37 to step 49 is executed again.

As described above, the reason why the prize ball does not drop to the position of the lower prize ball sensor 15 without inputting the ball presence signal from the lower prize ball sensor 15 in step 49 is that the prize ball from the prize ball tank 3 is a sprocket. In step 43, the upper prize ball sensor is bounced even though the prize ball does not actually drop (is not paid out) by bouncing on 10 and out of the detection area of the upper prize ball sensor 14.
There is a case in which 14 outputs a sphere-free signal from a sphere-present signal that was previously output. However, it is unlikely that such a bouncing will be repeated three times for the same ball, and if it is within that range, it is judged as a normal bouncing and the ball-cutting solenoid 11 is re-energized, but three times. In the above case, it is determined that the lower prize ball sensor 15 is defective on the side where the ball cannot be detected, and the pachinko game is stopped by the processing from step 44 to step 4.

Incidentally, the count value of the bound counter C added in step 50 becomes "0" when the power is turned on again or the reset switch 30 is operated after shifting to step 15, and again when shifting to step 37. When the safe ball enters either of the winning openings 19a and 19b, the value becomes "0" in step 30.

On the other hand, in step 49, the lower prize ball sensor 15
When the ball presence signal is input from the CPU 35, the CPU 35 confirms in step 52 that the absence ball signal is input from the lower prize ball sensor 15 (the dropped prize ball has passed the detection area of the lower prize ball sensor 15). Then, in step 53, "1" is subtracted from the payout counter M. When the payout counter M is not "0" at step 54, the CPU 35 returns to step 37 and repeats the above-mentioned prize ball payout process. When the payout counter M reaches 0 as a result of paying out a predetermined number of prize balls, the CPU 35 turns off the first or second display lamp 31, 32 which is turned on to display the payout process in step 55. Let

Therefore, the prize ball payout processing from step 37 to step 53 is repeated by the number written in the payout counter M (in this case, "13" or "7"), and the number of prize balls is paid out to the prize ball dish. Will be done. As described above, the prize ball payout process for the safe ball detected in step 16 is completed, and then the CPU 35 executes the safe ball drop process for collecting the safe ball in the ball collecting section.

First, the CPU 35 goes to step 56, where the safe ball drop flag E =
The value is set to 0, and it is determined in step 57 whether or not a sphere presence signal is input from the safe sphere sensor 27. When the sphere present signal is input, the CPU 35 energizes the safe sphere solenoid 22 in step 58 so that the safe sphere confirmed in step 16 remains and the safe sphere is dropped.

Next, the CPU 35 determines in step 59 and step 60 whether or not the no-sphere signal is input from the safe sphere sensor 27 within 100 ms. When the no-sphere signal is input, the safe-sphere solenoid 22 operates normally and the safe ball is dropped, and the CPU 35 sets the flag E to 1 in step 61, and then the step 6
Degauss the safe ball solenoid 22 with 2. If the CPU 35 does not input the no-sphere signal from the safe ball sensor 27 within 100 ms in steps 59 and 60, the safe ball solenoid 22 does not operate normally and the safe ball is not dropped. The safe ball solenoid 22 is demagnetized in step 62 without changing the value.

Then, in step 63, the CPU 35 drops the safe ball drop flag E =
If the flag E = 1, it is determined that the safe ball has fallen normally, and after waiting 0.2 s in step 64, the process returns to step 12. Then, the CPU 35 waits for the safe ball to enter the winning openings 19a and 19b again. If the flag E = 0 in step 63, the safe sphere does not fall normally, and the CPU 35 blinks the second display lamp 32 at 1 Hz in step 65 to notify the administrator of this situation. Pachinko game is stopped by stopping the load of each solenoid.

Therefore, the failure of the safe sphere sending device 21 and the safe sphere sensor
When the destruction of 27 occurs, the pachinko game is stopped by the processing of step 59 to step 63.

On the other hand, when the sphere presence signal is not input from the safe sphere sensor 27 in step 57, the CPU 35 directly proceeds to step 63, and in this step 63 it is determined that the flag E = 0. Then, as described above, in step 65, the second indicator lamp 32 is turned on.
It blinks at 1 Hz to notify the administrator of this situation, and the loads of the solenoids are stopped to stop the pachinko game.

As described above, the reason why the safe ball is determined not to exist in step 57 despite the fact that the safe ball is confirmed in step 16 is that the player malfunctions the safe ball sensor 27 It can be inferred that they tried to receive the payment. As the illegal means, for example, a safe ball sensor
It is possible to irradiate 27 with radio noise to induce a malfunction, or to insert a wire or the like through the gap in the front frame 1 to activate the safe ball sensor 27.

However, such payout of prize balls due to fraud is prevented in advance by the setting control conditions described above. That is, in step 29, the safe sphere sensor 27
Determine whether there is a sphere signal for 50 ms or longer. Again step
At 57, the presence / absence of a sphere presence signal of the safe sphere sensor 27 is determined again, and at steps 59 and 60, it is determined again whether or not the sphere presence signal is changed and input to the no-sphere signal within 100 ms. If these determination items are not satisfied, the subsequent processing is set not to be performed at all. Therefore, under such a set control condition, a strict illegal operation that meets all the conditions is impossible in reality, and should be executed even if the player attempts the illegal operation. It is not possible to prevent it, and it is possible to prevent it by proactively blocking misconduct.

In summary, in the pachinko machine of the present embodiment, the sensor 27 of the safe ball sending device 21 is provided with the movable iron piece 23 of the solenoid 22 as the electric stop release device for the original safe ball detection and prize ball detection payout. While the detection signal is being input with reference to the time point when one safe ball stopped at is detected as a reference, the ball-slicing device 9 performs the pay-out operation in units of one time based on the pay-out control command transmitted from the CPU 35. Go and eject a predetermined number of prize balls. After the prize balls are paid out (after the count detection of the lower prize ball sensor 15 is completed)
The solenoid 22 is once actuated to the release side and the movable iron piece 23
While releasing the safe ball from the above, the sensor 27 is returned to the original ball-free detection state due to the fall of the safe ball, and at this time, the solenoid 22 is returned to the original restraining side again and the movable iron piece 23 is stopped. Return to position.

Under this, the cheating of the safe ball sensor 27 (malfunction)
As a preventive measure against the illegal discharge of prize balls, the sensor 27 should be paid out while the prize balls are being paid out based on the detection status of the sensor 27 on the premise that there is no safe ball.
Is changed to the ball-free detection state, after the prize balls are paid out based on the ball-detected state of the sensor 27, and after that, the solenoid 22 is operated to the release side and thereafter (100 ms elapses). Also, in the case where the sensor 27 is still in the ball presence detection state, the CPU 35 causes “sensor abnormality” based on the determination of the detection setting condition, that is, the sensor 27 malfunctions due to the player's cheating (operation). If it is determined that the prize balls have been paid, the prize ball payout operation is immediately stopped or disabled, and the prize balls are prevented from being illegally discharged due to misconduct.

Further, in the pachinko machine of the present embodiment, with respect to the original ball removal of the stored prize balls, when the ball removal switch 28 that is located on the back side of the machine and can be operated from the front side is operated, the first operation of this operation signal ( In response to an input only once), the ball removal solenoid 17 is actuated to the ball removal side based on the ball removal control command transmitted from the CPU 35 to move the switching lever 16 to the release position of the ball removal passage 7. Hold switching. Under this condition, the ball cutting device 9 is kept in the payout state of the prize balls for a set time of 45 s, so that all the prize balls reaching the prize ball tank 3 side are discharged from the ball cutting device 9 to remove the balls. Passage 7
Is pulled out from the frame. After the set time for ball removal, the ball cutting device 9 is returned to the original pre-ball discharge state, while the ball removal solenoid 17 is returned to the payout side and the switching lever 16 is opened to the open position of the payout passage 6. Switch to and hold.

Under this condition, as a measure to prevent illegal winning of prize balls due to illegal operation of the ball-slot removal switch 28, the signal from the switch 28 can be input only once (once) in the CPU 35 when the pachinko machine is powered on again. It is set to invalidate all signals after the second time. With this, a player or the like who attempts to illegally obtain a prize ball holds the switching lever 16 at the open side position of the payout passage 6 and holds it illegally.
Even if the switch 28 is tampered with, only if it is the first time, it is possible to minimize the damage that only the prize balls remaining in the aircraft are illicitly discharged to the bowl plate side. After the replenishment, it is impossible to remove the ball by an illegal operation after the second time. Further, as a mischief, if the player illegally operates the switch 28 without being able to hold the switching lever 16 illegally, the remaining prize ball at that time is simply removed from the ball removing passage 7, and a new prize ball is extracted. Is definitely blocked.

Then, in the pachinko machine of the present embodiment, regarding the original safe ball classification detection and prize ball classification discharge for this, the safe ball that has entered the specific winning opening 19a is detected by the board surface sensor 18 and the game base 33 is detected. After transmitting to the signal conversion circuit unit side, finally input to the CPU35 via the signal lines 33a, 33b, while the safe balls that have entered all the winning holes 19a, 19b sensor 27 of the safe ball processing device 21 Detects one ball at a time and inputs the signal to CPU35. Under this, in CPU35,
Whether or not there is a classification detection input from the board sensor 18 side with respect to the safe sphere detection input time by the sensor 27, in other words, the detection condition of the sensor 18 is a high level signal when no ball is detected, a low level when a ball is detected The signal is judged, and the ball-slicing device 9 is operated to pay out on a one-time basis based on the respective paying-out control commands corresponding thereto, and the above-mentioned first and second
The second set number of prize balls is discharged separately.

Under this condition, as a measure for detecting the classification of safe balls and the prevention of illegal modification of the discharge prize balls, the detection condition of the board surface sensor 18 is inputted into the high level signal and the low level signal in the CPU 35. In the setting example, this low level signal can be input as valid only for the valid detection time (within 10 to 128 ms), and signals outside this time are processed as input disabled and a judgment of "signal abnormality" is made. It is set to disable prize ball payout. As a result, in the pachinko machine used in the game, if the signal lines 33a, 33b relating to the board surface sensor are cut or short-circuited in an attempt to illegally change the number of prize balls, the CPU 35 always outputs a low level signal. Against remaining input, the prize ball payout operation is immediately disabled and stopped based on the comparison with the valid detection time condition, and the subsequent prize ball payout is completely prohibited. At the same time, it also prevents unauthorized payment of the number of changes.

The present invention is not limited to the embodiment. For example, the pachinko machine of the above embodiment is provided with a ball cutting device 9 for paying out prize balls as the sprocket 10 rotates. 11 movable iron pieces 12 directly into the ball supply path 5
A ball cutting device may be provided to control the payout of prize balls by appearing and disappearing inside. Contrary to the above, the first set award ball number may be “13” and the second set award ball number may be “7” as the number of award balls paid out according to the safe ball classification detection condition.

[Effect of the Invention] As described in detail above, according to the pachinko machine of the first invention,
An excellent effect that a player can prevent an illegal act in which a safe ball sensor malfunctions and a prize ball is paid out can be prevented.

According to the pachinko machine of the second aspect of the present invention, it is possible to effectively prevent an illegal act in which a player operates a ball removal switch in the pachinko machine to pay out a prize ball. .

Furthermore, according to the pachinko machine of the third aspect of the invention, it is possible to prevent an illegal act in which a pachinko parlor arbitrarily changes the number of prize balls to be paid out.
