Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of changing the state of a movable ball receiving member into a closed state in which it is difficult to accept or does not accept a batted ball, and an open state in which it is easy to accept a batted ball. In a pachinko machine equipped with a variable hit ball winning device that converts a movable ball receiving member from an open state to a closed state by the weight of the ball hit by the ball, the variable hit ball winning device has a closed ball receiving device that operates a detector in response to the action of the ball hit for closing operation. This invention relates to a pachinko machine that is provided with a moving ball sensing member to prevent the continuation of the game if the movable ball receiving member does not change to the closed state even if a ball hit for a closing action wins a prize.

Pachinko machines have conventionally been equipped with a variable hit ball winning device that converts a movable ball receiving member from an open state to a closed state using the weight of a winning ball in an open state. However, in conventional pachinko machines, even if a ball hit for closing action that converts the movable ball receiving member from an open state to a closed state wins, the movable ball receiving member is not properly closed in response to the occurrence of the ball for closing action. It is not possible to check whether it has been converted to .

For this reason, fraudulent acts such as piano wire or the like are inserted into the inside of the pachinko machine and the movable ball receiver is left open, and balls become clogged, causing problems in the state changing operation of the movable ball receiver, resulting in unfair practices to players. profit,
Or, it may cause inconvenience such as giving a disadvantage.

The present invention has been proposed in view of the above, and includes a closing motion ball sensitive member that operates a detector in response to the action of a ball for closing motion, which converts a movable ball receiving member from an open state to a closed state by its own weight. The movable ball receiving member changes from the open state in response to a hit ball for closing action based on a status signal based on the signal from the above-mentioned detector and a reference signal from a reference setting device in which a reference value is set in advance. A proper operation determining section is provided that electrically determines whether the closed state has been changed, and a game interrupting means is activated in response to an improper signal transmitted from the proper operation determining section, thereby preventing fraudulent acts. To provide a pachinko machine that can reliably give a proper profit to players and allow them to play pachinko games with peace of mind.

The present invention will be explained below based on embodiments shown in the drawings.

As shown in FIG. 1, the pachinko machine 1 has a game section 4 surrounded by guide rails 3 on the surface of a game board 2, and inside the game section 4 are numerous obstacle nails (not shown),
Winning device 5..., special prize opening 6, variable batted ball prize device 7
etc. are arranged. Further, the front of the pachinko machine 1 is provided with a supply tray 8, a saucer 93, a firing operation section 10, etc. When a player operates the firing operation section 10, a ball firing device 11 whose driving source is a motor, solenoid, etc. is activated. After starting, the balls introduced from the supply tray 8 can be fired one by one. The fired ball enters the game section 4 via the guide rail 3, hits an obstacle nail, and flows down while being bounced. If the ball enters the winning device 5..., the special winning hole 6, or the variable batted ball winning device 7 while flowing down, it becomes a winning ball, but if it does not enter any of the winning holes, it enters the out hole 12 and becomes an out ball. . Note that when a batted ball enters any of the winning holes, a prize ball discharging device (not shown) provided on the back side of the game board 2 is activated, and the prize ball is discharged into the supply tray 8 or the receiving tray 9.

As shown in FIGS. 2 to 7, the variable hit ball winning device 7 has a horizontally elongated ball entrance 14 on a board 13 attached to the surface of the game board 2, and ball passage holes 15 on the left and right sides of the ball entrance 14. , 15 are opened, and pocket frames 17, 17 having lamp indicators 16, 16 are provided in front of the ball through holes 15, 15. Therefore, when the hit ball that has flowed down inside the gaming section 4 flows down into the pocket frame 17, the hit ball passes through the ball passage hole 15 and is ejected to the back side of the board 13, becoming a winning ball.

A horizontally long door plate 18 as a movable ball bearing member is rotatably mounted on a horizontal shaft 19 below the inner edge of the horizontally long ball entrance 14, and the center of gravity of the door plate 18 is centered on the horizontal axis 19.
By positioning the door plate 18 in front of the base plate 9, the door plate 18 is biased to tilt forward of the base plate 13 by its own weight. Note that a spring or the like may be used as the biasing means for the door plate 18.

Also, on the back side of the board 13, there is a partition plate 20 inside.
A frame 23 is provided, which is divided by a and 20b and has a general ball passage 21, 21 and a closed ball passage 22 that communicate with the ball inlet 14. The frame 23 has a door plate 18.
When the upright lock mechanism 24, which holds the ball upright and maintains it in a closed state that blocks the ball entrance, and the door plate 18, which tilts forward and opens the ball entrance 14, enters the open state, the ball hits the closed ball path 22. Door plate 18 unless you go inside.
A closing motion ball sensitive member 25 is provided which locks the ball from closing and activates a detector in response to the action of a ball entering the closing ball passage 22.

As shown in FIG. 5, the embodiment of the upright locking mechanism 24 shown in the drawings includes a circular arc surface 26 centered on the horizontal axis 19 and an engagement formed obliquely from the middle of the circular arc surface 26 toward the horizontal axis 19. A locking cam 28 having a snap edge 27 is provided facing rearward on one side of the base end of the door plate 18, and a cam engagement rod 29 extending obliquely downward and forward from the base end is provided at the rear of the frame 23. An upright locking member 31 having a weight rod 30 extending rearward from the base end and urging the engaging rod 29 to pivot forward is pivoted by a shaft 32. Therefore, the door plate 18
stands upright, as shown in Figure 6,
The cam engaging rod 29 located at the front and the locking edge 27 of the locking cam 28 are urged by the weight rod 30 to engage with each other, thereby maintaining the closed state in which the ball inlet 14 is closed.

On the back side of the frame body 23, a footboard portion 33 is provided at one end.
A swinging rod 36, which has a push-up part 34 at the other end and normally stands still by lowering the push-up part 34 under the force of a weight 35 provided near the push-up part 34, is pivotably mounted on a shaft 37. It has been done. The ball descending section 38 at the rear of the frame in which the footboard section 33 is movably housed is connected to an outlet of a guide gutter (not shown) which communicates with the special prize opening 6 described above. Therefore, special prize opening 6
The batted ball that enters the ball descends through the guide gutter into the ball descending section 3.
8. When a batted ball lands on the tread plate 33, the swinging rod 36 moves down the tread plate 33 at one end due to the weight of the batted ball, and moves down the tread portion 34 at the other end.
The push-up part 34 pushes up the weight rod 30 of the upright locking member 31. Heavy rod 3
0 rises, the cam engagement rod 29 retreats rearward and disengages from the locking edge 27 of the locking cam 28, leaving the door plate 18 in a free state. When the door plate 18 is in a free state, the door plate 18 tilts in a direction in which the upper end is tilted in front of the base plate 13 due to its own weight. When the regulating rod 39 extending rearward from one side of the door plate 18 comes into contact with the stopper 40 in the frame 23, it comes to rest and converts the ball inlet 14 into an open state. In addition, as shown in FIG. 7, the door plate 1
When permanent magnets 41a and 41b are embedded in the lower part of the horizontal shaft 19 of 8 and the back surface of the board opposite to the lower part with the same magnetic poles facing each other, the repulsive force of the permanent magnets 41a and 41b causes the door plate to 18
can be quickly and reliably converted from a closed state to an open state.

When the variable hit ball winning device 7 is changed to the open state as described above, as shown in FIG. The incoming ball hits the door plate 1.
8, the ball is in a state where it can be easily received into the ball inlet 14.
Further, in this open state, there is a risk that the ball will collide with the door plate 18, causing the door plate 18 to rotate and return to the closed state. Therefore, in this embodiment, a closing action ball sensitive member 25 for stabilizing the door plate 18 in the open state is attached to the frame 23 on the shaft 4.
2, it is pivoted so that it can swing freely.

As shown in FIG. 5, this closing motion ball sensitive member 25 has a ball receiving chamber 43 with an open front and bottom surface, and a ball receiving chamber 43 is provided with a ball receiving chamber 43 on the left and right sides thereof extending downward from the base end of the pivot. The leg pieces 44a, 44b each have a ball receiving piece 45 extending downward from the base end of the shaft on the rear surface thereof, and a weight 46 is provided behind the base end of the shaft. The distance between the leg pieces 44a and 44b is longer than the diameter of the sphere and shorter than twice the diameter of the sphere. When this closing action ball sensing member 25 is pivoted to the frame 23, as shown in FIG.
The leg pieces 44a, 44b and the ball receiving piece 45 are made to face from above into the closed ball movement passage 22 inside the partition plates 20a, 20b. In this way, the closing action ball sensing member 25
When faced from above into the closed ball passage 22, the eighth
As shown in the figure, one or both leg pieces 44a, 4
4b functions as a locking piece that closely engages with the upper surface of the door plate 18 in the open state. Note that the closing action ball member 25 is moved by the leg pieces 44a and 44b by the weight 46.
is urged to swing forward, but the stopping angle is regulated by a stopper 23' formed on the upper surface of the frame 23. Therefore, as shown in FIG. 8, even if the batted ball collides with the door plate 18 and flips up the door plate 18, the door plate 18 is prevented from rotating by the leg pieces 44a and 44b. Therefore, it will not return to the closed state.

In the above-mentioned open state, when a hit ball that has flown down inside the gaming section 4 lands on the door plate 18, the hit ball rolls due to the slight downward slope of the door plate 18, and the ball enters the ball entrance 14.
It flows into the closed ball passage 22 or the general ball passages 21, 21 inside the frame body 23 through the inside. Furthermore, the partition plate 20
On the upper surface of the door plate 18 in front of the partition plates 20a and 20b, substantially triangular flow dividing protrusions 47 and 47 with raised rear ends are provided. The flow direction is changed by the flow dividing protrusion 47, and the closed ball passage 22 or the general ball passage 2
1. Therefore, the ball may get caught between the door plate 18 and the partition plates 20a, 20b,
Or it will not get stuck on the door plate 18.

The batted ball that has entered the general ball passage 21 is
The ball is ejected to the back side of the ball and becomes the winning ball.

On the other hand, the ball rolling toward the closed ball passage 22 passes between the leg pieces 44a and 44b and then passes through the door plate 1.
It rolls on a ball mounting part 48 having a substantially L-shaped cross section formed by extending the base end of the ball 8, enters the ball receiving chamber 43 of the closing action ball sensing member 25, and presses the ball receiving piece 45 backward. The ball moves forward and stops when it hits the upright stopper 48 of the ball mounting section 48. When the ball catching piece 45 is pressed by a batted ball, the closing movement ball sensing member 25 integrally swings rearward, so that the leg pieces 44a and 44b functioning as locking pieces touch the upper surface of the door plate 18. The door plate 18 is left in a free state. When the door plate 18 is in a free state, the door plate 18 returns to the upward direction on the sloped upper end of the door plate due to the weight of the ball on the ball mounting portion 48, stands upright, and opens the ball entrance 14. Restore to closed state. When the door plate 18 is restored to its upright closed state, as shown in FIG.
The tip of the door plate 9 comes off the arcuate surface 26 and engages with the locking edge 27 to hold the door plate 18 in a closed state. Note that when the door plate 18 is changed from the tilted open state to the upright closed state, the hit ball on the ball mounting section 48 falls from the ball mounting section 48 and is ejected to the back side of the board 13, becoming a winning ball.

Since the door plate 18 has a long width, in the open state, it can receive a plurality of batted balls into the ball entrance 14 in a very short time or almost simultaneously, and the closed ball movement passage 2
In some cases, the ball is rolled in multiple rows toward the ball. In this case, in this embodiment, the distance between the legs 44a and 44b of the closed ball sensing member 25 is set to be equal to or larger than the ball diameter.
Since the diameter is less than twice the ball diameter, when the horizontally lined up balls enter the ball receiving chamber 43, the leg pieces 44a, 44b
The liquid flows in a lined-up state. Therefore, it is possible to prevent a plurality of batted balls from competing in the closed ball movement passage 22 and clogging the ball, or from being caught between the partition plate 20 and the leg piece 44 and clogging the ball. Therefore, the door plate 18 smoothly returns from the open state to the closed state due to the weight of the batted ball.

In this way, in the normal state, the variable hit ball winning device 7 converts the door plate 18 from the closed state to the open state by the hit ball guided from the special winning hole 6, and the closed ball hit ball that flows into the closed ball path 22. This restores the door plate 18 from the open state to the closed state. The time required for the door plate 18 to convert from the open state to the closed state falls within the standard time if the conversion operation is appropriate. That is, by comparing the time from when the closing action batted ball wins until the door plate 18 closes, or the number of signals transmitted from the transmitter within that time with a reference value, the door plate 18
It is possible to determine whether the state conversion operation is appropriate or inappropriate.

Therefore, in the present invention, the variable batted ball winning device 7 is provided with a detector for detecting batted balls for closing operation, and a status signal based on a signal from the detector and a reference signal from a standard setting device in which a reference point is set in advance are used. A proper operation determining section is provided to determine whether the door plate 18 is in an appropriate or inappropriate state, and when the operation of the door plate is inappropriate, the proper operation determining section generates an inappropriate signal.

In the embodiment of the detector shown in the drawings, a photocoupler 51 consisting of a light emitting source 49 and a light receiver 50 is disposed above the back surface of the mounting board 13, and a closing motion ball sensitive member 25
A light shielding portion 52 formed at the upper end faces the gap between the light emitting source 49 and the light receiver 50. Then, the positional relationship between the photo puller 51 and the light shielding part 52 is determined so that the light shielding part 52 blocks the light from the light emitting source 49 only when the closing action ball sensitive member 25 is pressed by the closing action ball.

That is, as shown in FIG. 7, in the closed state where the door plate 18 closes the ball entrance 14, the closing action ball sensing section
5 is set so that the lower end thereof comes into contact with the back surface of the door plate 18 and remains stationary, and the light shielding part 52 is deviated from the optical axis of the light emitting source 49 so that the detection signal from the photocoupler 51 is not generated. Furthermore, as shown in FIG. 8, even in the open state where the door plate 18 is tilted forward, the closing operation ball sensing portion
2 is rotated by the bias of the weight 46 and the light shielding part 5
2 is separated from the photocoupler 51, the detection signal of the photocoupler 51 is not generated. Then, when the ball for closing action presses the ball sensitive member 25 for closing action and rotates, the light blocking portion 52 blocks the light from the light emitting source 49, as shown in FIG. occurs.

Note that in the photocoupler 51, when the ball for the closing operation falls from above the door plate 18, the light shielding part 52 is deviated from the optical axis of the light emitting source 49 due to the bias of the weight 46, so that no detection signal is generated.

The embodiment of the proper operation determination section 53 shown in FIG. a counter 56 that counts and outputs an output when the counted number exceeds a reference value as a reference signal sent from the reference setter 55;
It consists of a flip-flop 57, etc., which inputs the output from the counter 56 as a set signal, and sends out an inappropriate signal when set.

Note that if the counter 56 can count the pulse signals from the pulse generator 54 and output an H level signal to set the flip-flop 57 when the count value exceeds the reference value from the reference setter 55, then It may be an up counter or a down counter.

In the closed state in which the door plate 18 closes the bulb entrance 14, no detection signal is generated from the photocoupler 51, so the pulse transmitter 54 does not operate. Therefore, flip-flop 57 maintains its reset state and does not issue an invalid signal. Also special prize opening 6
Even in the open state in which a ball is hit and the door plate 18 is tilted forward, the photocoupler 51 does not generate a detection signal and therefore does not transmit an inappropriate signal. In this open state, when a batted ball that enters the ball entrance 14 enters the closing ball passage 22 and becomes a closing ball, the photocoupler 51 generates a detection signal by the light shielding part 52 under the action of the closing ball. . Photocoupler 5
1 generates a detection signal, pulse generator 54 is started and sends a pulse signal to counter 56. Then, before the number of pulse signals input to the counter 56 reaches the reference value, the door plate 18 is restored to the closed state, the detection signal from the photocoupler 51 disappears, and the operation of the pulse generator 54 is stopped. Since the output of the counter 56 remains at L level, no inappropriate signal is generated. Note that the counter 56 inputs a signal obtained by delaying the detection signal from the photocoupler 51 by the delay circuit 58 as a reset signal, so that it is automatically reset after determining whether the state conversion of the door plate 18 is appropriate or inappropriate. .

However, as shown in FIG.
If a ball that enters the ball entrance 14 becomes a ball for closing operation when the door plate 18 is illegally left open due to the above-mentioned reason, the detection signal of the photocoupler 51 is generated and the counter 56 is activated as a pulse generator. Start counting pulse signals from 54. In such a state, the door plate 18 does not rotate back, so the ball for the closing operation does not fall from the top of the door plate 18. Therefore, the photocoupler 51 continues to generate the detection signal and continues to operate the pulse generator 54. Therefore, a signal greater than the reference value set by the reference setting device 55 is sent to the counter 56. When the counter 56 receives a signal exceeding the reference value,
The flip-flop 57 is set by outputting an H level signal. When the flip-flop 57 is set, a game interrupting means is activated by the H level signal outputted as an inappropriate signal, and the pachinko game is forcibly interrupted.

The embodiment of the game interrupting means shown in FIG. 11 connects the flip-flop 57 to a relay 60 that is activated by an inappropriate signal, and when the relay 60 is activated, the power supply to the motor 11' of the ball launcher 11 is stopped.
The firing device 11 is stopped regardless of the operation of the firing operation section 10. Therefore, the door plate 18 may be opened illegally using the piano wire 59 or the like,
Alternatively, if the door plate 18 does not return to the closed state due to ball jamming, it is possible to prevent the game from continuing.

Note that an inappropriate signal may cause a warning light in a pachinko machine or a central control room to turn on or blink, or a warning buzzer to sound.

The proper operation determination unit 53 is a flip-flop 57.
continues to output an inappropriate signal until it is reset. Therefore, in the embodiment shown in FIG. 11, when the clerk operates the reset switch 61, the flip-flop 57 is reset by the signal from the reset switch 61 via the OR gate 62. Also, a timer 63 is started by an inappropriate signal and outputs a reset signal after a certain period of time has elapsed.
It may be reset automatically.
In this way, if the reset timer 63 is provided,
If a fraudulent act is committed, the game will be interrupted and the game cannot be resumed until a certain period of time has elapsed, so this is an effective means for preventing fraudulent acts.

In addition, in the above explanation, the game interrupting means is the motor 1.
1', but any configuration may be used as long as the game can be interrupted by an inappropriate signal. For example, another embodiment of the game interrupting means shown in FIG. 12 is one in which a solenoid 64 is provided on the back side of the game board 2, and a blocking rod 65 that blocks the ball passage 3' on the guide rail 3 is connected to the solenoid 64. When an inappropriate signal is generated, the ball path 3' is blocked by a blocking rod 65, and all the balls hit are made into foul balls, thereby preventing the game from continuing. Therefore, the relay 60
Connect the solenoid 64 to the flip-flop 5
It is only necessary that when an inappropriate signal is transmitted from 7 and the relay 60 is activated, the solenoid 64 is energized so that the blocking rod 65 blocks the ball passage 3'.

Another embodiment of the game interrupting means shown in FIG.
Solenoid 6 is installed on the opening/closing panel 66 on the front of the pachinko machine.
A shutter 68 is provided which is operated by a shutter 7, and movement of the shutter 68 opens and closes a ball passage port 69 communicating between the supply tray 18 and the ball firing position at the lower end of the guide rail 3. Therefore, when an inappropriate signal is sent from the flip-flop 57, the solenoid 67 is energized, and the shutter 68 closes the ball passage opening 69 to prevent the balls in the supply tray 8 from being supplied to the ball firing position, thereby preventing the continuation of the game. can do.

In the above embodiment, the photocoupler 51 was used as a detector, but the detector of the present invention can be operated by the closing action ball sensing member 25 to detect that a ball hit for closing action has won a prize. It can also be a configuration. For example, it may be a micro switch, a reed switch, etc.

As explained above, according to the present invention, the variable hit ball winning device includes a closing ball sensitive member that operates a detector in response to the action of a ball for closing action that converts the movable ball receiving member from an open state to a closed state by its own weight. and a status signal based on the signal from the detector;
A proper operation determination unit electrically determines whether the movable ball receiving member has changed from an open state to a closed state in response to a winning of a ball hit for closing action based on a reference signal from a reference setting device in which a reference value is set in advance. Since the game interrupting means is activated by the inappropriateness signal sent from the appropriateness determining section, even if a fraudulent act is committed, the game will be automatically interrupted and the perpetrator will not receive an unfair advantage. Giving can be prevented.

In addition, since appropriate profits can be given to players, the game parlor can provide fair services to all players and provide healthy pachinko games.
