Description

The present invention relates to a ball cutting device for a pachinko machine.

[Prior Art and Problems] In general, prize balls to be paid out to a player during a pachinko game are stored in a prize ball tank, and when a safe ball enters the prize hole, a predetermined number of prize balls are stored in the prize ball tank. Is dispensed to the prize ball dish through the ball supply path by the ball cutting device.

However, if foreign matter such as dust enters the ball cutting device, the movement of the prize balls may be obstructed and ball clogging may occur. As a result, the prize balls are not paid out to the player and the pachinko game is interrupted. There's a problem.

On the other hand, as one type of ball cutting device, a rotating ball feeder facing the ball supply path for prize balls and
Equipped with a solenoid that controls release and a sensor that detects the presence or absence of prize balls that are received by the rotating ball feeder and discharged.The solenoid is released based on the ball detection condition of the sensor as the payout of prize balls to the safe balls. A type has been proposed in which, when actuated, the rotary ball feed body rotates to pay out prize balls.

However, if prize balls that should be continuously sent from the prize ball tank side are irregularly (intermittently) supplied to the ball supply path for some reason, the prize balls bounce off the rotating ball feeder and are once displaced upward. After doing, it may be accepted again. For the prize ball that the sensor bounces against such a situation,
The detection conditions of the ball presence detection state and the ball absence state have changed, so the rotary ball feed body does not accept the bouncing prize ball due to the release operation of the solenoid when the sensor detects the ball presence. There is a case where the blank is rotated as it is. As a result, the prize balls may not be paid out even though the payout operation is performed, and in one payout operation, the number of prize balls actually paid out may not reach the specified number. is there.

As described above, although the ball cutting device has various problems, the measures are not taken yet.

It is an object of the first invention to provide a ball cutting device for a pachinko machine, which can prevent ball clogging due to intrusion of foreign matter.

A second object of the present invention is to provide a ball-slicing device for a pachinko machine, which can prevent erroneous detection of a prize ball sensor and can always pay out a specified number of prize balls.

[Means for Solving the Problems] A first invention is to respond to an input of a winning detection signal, and a ball-slicing device capable of discharging a predetermined number of award balls based on a payout operation in a unit corresponding to one winning. An electronic control circuit device for ejecting a prize ball capable of operating the ball cutting device with a control command, and in the ball cutting device, an upper sensor for confirming and detecting the presence or absence of a prize ball in the ball supply path, and a ball supplying device. A rotary sprocket that can send out prize balls one by one in the road, a solenoid that can switch and control stop release means for this sprocket, and prize balls discharged as the sprockets rotate can be detected one by one. The electronic control circuit device is provided with a lower sensor, and the electronic control circuit device is provided with a CPU (central processing unit) including a payout control command means, and necessary input / output control means,
The ball cutting device is provided with a ball clogging judging means for judging a ball clogging in the ball cutting device, and a vibration generation control means for generating vibration in the ball cutting device, and a solenoid of the ball cutting device releases a sprocket to allow rotation. In the case where the lower sensor does not change to a predetermined detection state for a set detection time on the premise of the prize ball to be discharged, the ball clogging determination means determines whether a ball clogging has occurred. In addition to the above, the vibration generation control means sets the solenoid to generate vibration due to the intermittent operation of excitation and degaussing when the ball clogging determination means determines that the ball is clogged. .

A second invention is a ball cutting device capable of discharging a predetermined number of prize balls based on a payout operation in a unit of one time corresponding to one winning, and a control command for the ball cutting device in response to input of a winning detection signal. With an electronic control circuit device for discharging prize balls,
In the ball cutting device, an upper sensor for confirming and detecting the presence / absence of prize balls in the ball supply path, a rotary sprocket capable of sending out the prize balls in the ball supply path one by one, and a stop / release means for the sprocket. A solenoid that can switch and control
A lower sensor capable of detecting the prize balls discharged by the rotation of the sprocket one by one, and the electronic control circuit device includes a CPU (central processing unit) including discharge control command means; In addition to the necessary input / output control device and the like, a payout failure detection means for determining a prize ball payout failure of the ball cutting device is provided, and the upper sensor in the prize ball payout operation process by the rotation of the sprocket of the ball cutting device. When the sensor does not change to the sphere presence detection condition within a set time from the time when the sphere has changed to the ball non-existence detection condition, the prize deficiency determination means determines the prize ball payout failure, and the payout control command means The gist is that the payout command is set to be executed again.

[Operation] In the first aspect of the invention, when the lower sensor does not detect the paid prize ball even though the solenoid allows the sprocket to rotate, it is determined by the ball clogging determination means that a ball clogging has occurred. The vibration generation control means alternately excites and demagnetizes the solenoid to apply vibration to the sprocket. As a result, the ball clogging is eliminated and prize balls are paid out.

In the second aspect, when the prize ball supplied from the prize ball tank collides with the sprocket and jumps upward, the upper sensor does not detect the prize ball at the moment of the jump.
As a result, the rotation of the sprocket is blocked and the payout process ends even though the prize balls have not been paid out. At this time, since the lower sensor does not detect the prize ball, the defective payout determination means determines the defective payout, and the payout control command means executes the payout again. Therefore, a predetermined number of prize balls are always paid out.

[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).

FIGS. 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 on one side of the ball supply path 5. Has been done. 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 locked 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 is rotatably attached to a location where the ball supply path 5 branches into a payout path 6 and a ball removal path 7. This switching lever 16 is driven by a ball-removing solenoid 17, and is moved to a position where the ball-removing passage 7 side shown in FIG.
A switching operation is performed between two positions, that is, a position for closing the dispensing passage 6 side shown in the figure. Incidentally, the switching lever 16 in the normal state 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, and the specific winning opening 19a is provided with a wall surface sensor 18 as a winning category detecting means. It is provided so as to detect the entry of a safe ball into the specific winning opening 19a. In addition, the safe balls that have entered the winning holes 19a, 19b are designed to flow into the safe ball passage 20, and one safe ball is detected on one side of the 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 the safe ball solenoid 22 of the safe ball sending device 21, and a movable iron piece 23 is rotatably 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 turning piece
The lower operation corner 24a of 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 in this state, the movable iron piece 23 is attracted to the core 22b of the solenoid 22 and the tip of the movable iron piece 23 is withdrawn from the safe ball passage 20 as shown in FIG. At the same time, the rotating iron piece 23 is pushed by the tip of the movable iron piece 23.
24 rotates counterclockwise, and the blocking corner 24b moves the movable iron piece 2
Safe ball passage 20 one safe ball above projecting point 3
It projects inside 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
It is stopped at and is 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 input switch 28 for drive input is provided.
Furthermore, a control box is provided on the lower side of the back surface of the front frame 1.
29 is installed, 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.

In the pachinko machine of the present embodiment, the original prize ball payout for the detection of the safe ball is performed as follows based on the electrical configuration and the setting of the control process described later. That is,
In the safe sphere sending device 21, it is determined whether or not the detection signal from the board sensor 18 is input, with reference to the time when each safe sphere is detected to stay. And "with input" and "without input" of the detection signal of the board surface sensor 18
On the basis of the payout control command in response to the condition, the first set award ball number and the second set award ball number, which will be described later, are classified in the payout operation permitted once by the ball cutting device 9. It can then be discharged. After the payout of the prize balls is completed (after the count number detection by the lower sensor 15 is completed), the safe ball sending device 21 releases and discharges the safe balls to restore the original state.

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 CPU) and drive circuits 36 to 40 are housed inside the control box 29 (electronic control circuit device for discharging prize balls). 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 the drive circuits 36 to 40, respectively. In the pachinko machine of this embodiment, the game board
Although 33 is installed outside the control box 29, it may be installed inside the control box 29.

The CPU 35 includes a ball clogging determination means 35a, a dispensing failure determination means 35c, a vibration generation control means 35b, and a dispensing control command means 35d.

The first to fourth prize ball number setting devices 42 to 45 are the number of prize balls paid out by the ball cutting device 9 (basically a decimal number) corresponding to the safe ball classification detection condition set in the game content. It is for presetting two ways, such as
Two kinds of level signals are selectively input to the 5 input side.

The configuration and setting conditions of the prize ball number setting devices (42 to 45) 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.

Next, the operation of the pachinko machine configured as described above
~ It demonstrates according to FIG.

7 and 8 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, one of the set number of prize balls will be 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, 18, 27 and switches 28, 30 are also written to RAM46. Furthermore, CPU3
In step 6, it is determined whether or not the detection signal is input from the board surface sensor 18 (whether or not a safe ball has entered the specific winning opening 19a), and if the detection signal is input, it is built in the RAM 46. "1" is added to the prize ball number selection counter N and the process proceeds to step 7. 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. become.

Next, based on the detection signal read in step 5 in step 7, 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 8 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 ball removing passage 7 side, and the player is prevented from being unjustly 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 8, and stops the loads of the solenoids and the like to play the pachinko game. Discontinue.

When the prize ball leaks from the sprocket 10 in this way, it is presumed that some sort of failure has occurred in the ball cutting device 9. Therefore, at this time, the pachinko game is stopped as described above, and it is possible to prevent the prize balls from being paid out to the player.

Then, in order to restart the pachinko game, it is necessary to turn off the power of the pachinko machine and then turn it on again, or operate the reset switch 30, and when either of them is performed, the CPU 35 executes the processing from step 1 above. Try again. Incidentally, after that, there are some cases where the pachinko game is stopped by stopping each load in this way, but at any time, the pachinko game is restarted by turning on the power again or operating the reset switch 30.

Regarding "Cancel of pachinko machines" in the text,
Specifically, it refers to the suspension or suspension (inability) of the prize ball payout operation.

On the other hand, when the lower prize ball sensor 15 does not detect two or more prize balls in step 7, the CP 35 determines that the ball cutting device 9 is normal, and in step 9, 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. Then, under the setting 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 by the normal operation of the ball cutting device 9, the sensor 15
When a signal indicating that a ball is present is input for 10 s or more, the CPU 35 determines that the sensor 15 has failed (error). In this case, CPU3
In step 10, the second indicator lamp 32 is blinked at 4 Hz via the drive circuit 40 to inform the administrator of this situation, and the loads of the solenoids are stopped to stop the pachinko game.

Even if the lower prize ball sensor 15 detects only one prize ball in step 7 and the process proceeds to step 9, the lower prize ball sensor 15 continues to detect the prize ball that is falling for 10 seconds or more. There is no such thing. Therefore, in this case as well, the lower prize ball sensor
The process of step 10 is executed assuming that 15 has failed.

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 9, the CPU 35 determines that the lower prize ball sensor 15
Is determined to be normal, and it is determined in step 11 whether or not 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. Transition to 12. Then, in step 12, 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 is operated for 0.5 s or more in step 12, is the CPU 35 operating this ball removal switch 28 in step 13 only after turning on the power of the pachinko machine? If it is the first time that the switch operation is performed, a ball removal process described later is executed in step 14. 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, and in this case, in step 13, what is done by the ball removal switch 28 is detected. Even if it is operated once, the ball removing process of step 14 is not executed.

The ball removal processing in step 14 described above is performed based on the "ball removal routine" shown in FIG. First, in step 15, 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 is executed. Next, in step 16, the CPU 35 excites the ball removal solenoid 17 to switch the switching lever 16 to close the payout passage 6 side and open the ball removal passage 7 side. Further, the CPU 35 executes step 17
0.2s until the switching operation of the switching lever 16 is completely completed with
After waiting, the ball cutting solenoid 11 is excited in step 18 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 19 (after collecting all the prize balls in the prize ball tank 3 in the ball collecting section)
At 20, 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 21,
In step 22, de-bulge solenoid 17 is demagnetized to switch lever
16 is switched to open the payout passage 6 side and close the ball removing passage 7 side to return to the initial state. Then, the CPU 35 turns off both display lamps 31 and 32 which are alternately blinking in step 23.

On the other hand, when the ball presence signal is input from the safe ball sensor 27 in step 11, the CPU 35 assumes that the player has started the pachinko game and the 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 24, the CPU 35 determines whether or not the sphere 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 longer, the CPU 35 sets the bound counter C, which will be described later, to "0" in step 25.

Next, in step 26, the CPU 35 determines 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 number of prize balls in step 27 is paid out in the RAM 46. Write to M. Further, the CPU 35 subtracts “1” from the prize ball number selection counter N in step 28,
At 29, the second display lamp 32 is turned on and the process proceeds to step 32.

On the other hand, when the count value of the prize ball number selection counter N is "0" in step 26, the CPU 35 writes "7" set as the first set prize ball number in step 30 into the payout counter M. Further, the CPU 35 turns on the first display lamp 31 in step 31, and proceeds to step 32.

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 The set prize ball number “7” of 1 will be written.

Further, in step 32, the CPU 35 determines whether or not a ball-existing 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-existing signal. If so, the ball cutting solenoid flag F is set to 0 in step 33, and the ball cutting solenoid timer is cleared and started in step 34. In addition, this ball-cutting solenoid timer is designed to time up in 128 ms.

Next, in step 35, the CPU 35 determines whether or not the ball-cutting solenoid timer has timed out. If not, in step 36, the ball-cutting solenoid flag F is determined.
= 0 is determined. Since this solenoid flag is set to F = 0 in step 33, the CPU 35 determines in step 3
Moving to 7, the ball cutting solenoid 11 is excited to make the sprocket 10 rotatable.

Then, when the CPU 35 inputs the no-sphere signal (ON signal) from the upper prize ball sensor 14 in step 38, the prize ball located on the upper prize ball sensor 14 falls as the sprocket 10 rotates, 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 40 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 38, the CPU 35 proceeds to step 39. Then, when a ball presence signal (OFF signal) is input from the lower prize ball sensor 15 in this step 39, 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 40 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 38, and the ball-present signal is not input from the lower prize ball sensor 15 in step 39, the CPU 35 indicates that the prize ball has fallen normally. If not, the process returns to step 35.

On the other hand, when the CPU 35 determines in step 35 that the ball-cutting solenoid timer has timed out (128 ms has elapsed), it clears the solenoid timer in step 41 and inverts the ball-cutting solenoid flag in step 42 (in this case, flag F). = 0 is inverted to F = 1), and the process proceeds to step 36. The CPU 35 proceeds to step 43 because the ball-cutting solenoid flag is F = 1 in step 36. Then, the CPU 35 degausses the ball cutting solenoid 11 in step 43, and then determines in step 38 and step 39 whether or not the prize ball has normally dropped. When the CPU 35 determines that the prize ball has dropped normally, the CPU 35 proceeds to step 40 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 35 and executes the processing from step 35 to step 39 again.

Therefore, the CPU 35 inverts the flag in step 42 every time the ball-cutting solenoid timer times out in step 35 (every 128 ms), and executes either step 37 or step 43 accordingly. Then, when step 37 is executed, the ball-turning solenoid 11 is excited,
When step 43 is executed, the ball cutting solenoid 11 is demagnetized. As a result, the ball-cutting solenoid 11 can be excited and demagnetized.
It will be repeated every 128 ms.

Therefore, for example, Polylon (trademark) for polishing pachinko balls
When the fall of the prize ball is obstructed by foreign matter such as, the ball cutting solenoid 11 intermittently operates every 128 ms to vibrate the sprocket 10 to drop the foreign matter and drop the prize ball normally. be able to. Further, when the ball-turning solenoid 11 is operated intermittently, the total excitation time is shorter than when the ball-turning solenoid 11 is operated intermittently at a long time interval, so that heat generation of the solenoid 11 is prevented. It

Next, after the excitation of the ball-cutting solenoid 11 is stopped in step 40, the CPU 35 determines in step 44 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 45, "1" is added to the bound counter C which has been "0" until now, and at step 46, it is determined whether the count value is 3 or more.

When the count value of the bound counter C is 3 or more,
The CPU 35 shifts to the step 10, notifies the manager of this situation by blinking the second display lamp 32 at 4 Hz, and stops the load of each solenoid and stops the pachinko game. If the count value of the bound counter C is less than 3, the CPU 35 returns to step 32 and executes the prize ball payout process from step 32 to step 44 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 44 is that the prize ball bounces on the sprocket 10. Is mentioned. That is, the prize ball tank 3
The prize balls are not supplied continuously as shown in FIG. 1, and rarely reach the sprocket 10 with a gap formed between the prize balls. At this time, the lowermost prize ball collides with the sprocket 10 and bounces upward, and at the moment of the bounce, the upper prize ball sensor 14 outputs a ball absence signal from the ball presence signal previously output. Then, the CPU 35, which has received the signal, erroneously determines that the prize ball has fallen in step 38 despite the fact that the prize ball has not actually dropped (is not paid out), and demagnetizes the ball-cutting solenoid 11 in step 40. It will end up.

Therefore, when the defective payout of the award balls occurs, the award balls can be paid out by executing the award ball payout process from step 32 to step 44 again. Further, when the payout failure occurs three times in succession even though the payout process is repeated, the steps 44 to 46 are executed.
Since the pachinko game is stopped by the processing of 1, it is possible to prevent troubles due to defective payout.

Incidentally, the count value of the bound counter C added in step 46 becomes "0" by re-entering the power source or the operation of the reset switch 30 after shifting to step 10, and again when shifting to step 32. When the safe ball has entered one of the winning openings 19a, 19b, the above step 2
It becomes "0" at 5.

On the other hand, in step 44, the lower prize ball sensor 15
When the ball presence signal is input from the CPU 35, the CPU 35 confirms in step 47 that the ball absence 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 48, "1" is subtracted from the payout counter M. Then, when the payout counter M is not "0" at the step 49, the CPU 35 returns to the step 32 and repeats the award ball payout process. When the payout counter M reaches 0 as a result of paying out the 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 50. Let

Therefore, the prize ball payout processing from step 32 to step 48 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 plate. Will be done. As described above, the prize ball payout process for the safe ball detected in step 11 is completed, and then the CPU 35 executes the safe ball drop process for collecting the safe ball in the ball collecting unit.

First, in step 51, the CPU 35 drops the safe ball drop flag E = 0.
Then, in step 52, it is determined whether or not a sphere presence signal is input from the safe sphere sensor 27. When the sphere presence signal is input, the CPU 35 energizes the safe sphere solenoid 22 in step 53 so that the safe sphere confirmed in step 11 remains and the safe sphere is dropped.

Next, the CPU 35 determines in step 54 and step 55 whether or not the no-sphere signal is input from the safe sphere sensor 27 within 100 ms. When the no ball signal is input, the safe ball solenoid 22 operates normally and the safe ball is dropped, and the CPU 35 sets the flag E to 1 in step 56,
Degauss the safe ball solenoid 22 with 7. If the CPU 35 does not input the no-sphere signal from the safe ball sensor 27 within 100 ms in steps 54 and 55, the safe ball sending device 21 does not operate normally and the safe ball is not dropped. Step 5 without changing the safe ball drop flag
Degauss the safe ball solenoid 22 with 7.

Then, in step 58, 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 59, the process returns to step 7. 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 58, the safe ball does not fall normally, and the CPU 35 blinks the second display lamp 32 at 1 Hz in step 60 to notify the administrator of this situation, and Pachinko game is stopped by stopping the load of each solenoid.

On the other hand, if the sphere presence signal is not input from the safe sphere sensor 27 in step 52, the safe sphere sensor 27
The CPU 35 proceeds to step 58 and determines that the flag E = 0 in step 58 because the output of the ball presence signal in 11 is due to an illegal act of the player. Then, as described above, in step 60, the second display lamp 32 is blinked at 1 Hz to notify the manager of this situation, and the load of each solenoid is stopped to stop the pachinko game.

In this way, the pachinko machine of this embodiment is a ball cutting solenoid.
Even though 11 allows the sprocket 10 to rotate, in steps 38 and 39, the upper or lower prize ball sensor 14, 1
CPU35 (ball clogging determination means) that determines that a ball clogging has occurred when 5 does not detect the paid prize ball, and this CPU35
When the ball clogging is determined, the vibration generation control means 35b of the CPU 35 for generating vibration by alternately repeating excitation and demagnetization of the ball cutting solenoid 11 in steps 37 and 43 is provided.

Therefore, when a foreign substance enters the ball supply path 5 to hinder the movement of the prize ball, the sprocket 10 is vibrated by alternately repeating excitation and demagnetization of the ball cutting solenoid 11. As a result, the ball clogging is eliminated and the prize balls can be paid out.

Further, the pachinko machine of the present embodiment, the lower prize ball sensor 15 for detecting the prize ball dropped from the sprocket 10, the upper prize ball sensor 14 on the sprocket 10 in step 38 along with the downward movement of the prize ball. Despite no longer detecting the prize ball at the bottom position, when the prize ball is not detected by the lower prize ball sensor 15 within 100 ms in step 44, the CPU 35 determines that the prize ball is not paid out. Step again to the payout control means 35d
The CPU 35 is provided with a payout failure determination means 35C for making a payout from 32 to step 44.

Therefore, when the prize ball from the prize ball tank 3 bounces on the sprocket 10 and the upper prize ball sensor 14 is erroneously detected,
Since the lower prize ball sensor 15 does not detect the prize ball, it is determined that the prize ball is not actually paid out, and the payout is executed again. As a result, a predetermined number of prize balls can always be paid out.

The present invention is not limited to the above-mentioned embodiment, and, for example, in the above-mentioned embodiment, steps 44 to
At 46, if the prize balls from the prize ball tank 3 bounce on the sprocket 10 and the prize balls are not paid out even after the payout is repeated three times, the pachinko game is stopped in step 10, but such a number of times limit is imposed. Instead of providing the prize balls, the payout may be continued any number of times until the prize balls are paid out.

Further, in the above embodiment, the ball cutting solenoid 11 blocks the rotation of the sprocket 10 every time one prize ball is paid out,
Although a predetermined number of prize balls are paid out by repeating the payout a predetermined number of times, the prize balls are continuously paid out while the rotation of the sprocket 10 is allowed, and of the prize balls paid out by the lower prize ball sensor 15. When it is determined that the number has reached a predetermined number, the rotation of the sprocket 10 may be blocked and the payout may be stopped. Furthermore, for a certain number of prize balls,
The sprocket 10 may be allowed to rotate to a slightly smaller number, and then the sprocket 10 may be prevented from rotating one by one.

[Effects of the Invention] As described in detail above, the ball cutting device for a pachinko machine according to the first invention has an excellent effect that it is possible to prevent ball clogging due to intrusion of foreign matter.

Further, according to the ball cutting device of the pachinko machine of the second aspect of the present invention, it is possible to prevent an erroneous detection of the prize ball sensor and always pay out a prescribed number of prize balls.
