Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides game balls used in pachinko games and prize balls used as prize balls in separate systems in one pachinko machine, and a ball exchange device between the two systems. is installed, and while there is a prize ball in the prize ball tray that receives the prize ball, the ball exchange device enables the game ball to be exchanged with the prize ball, and supplies the game ball to the ball firing position to play the pachinko game. In a pachinko machine that is designed to allow game balls to be replaced, when there are no game balls left in the game ball storage chamber for storing game balls, the replacement work of the ball replacement device is automatically stopped, and thereby the game balls are constantly set. To provide a game stopping device for a pachinko machine which allows prize balls and game balls to be exchanged with a given exchange value.

The present inventors have already proposed a pachinko game machine in Japanese Patent Application No. 167698/1983, which allows games to be played using two types of pachinko balls: game balls and prize balls.

This pachinko game machine is equipped with a game ball storage chamber for storing a predetermined number of game balls inside the machine, and communicates this storage chamber with the starting end of the firing band, and allows balls to fly into the safe opening provided on the game board surface. The ends of the safe ball passage for guiding safe balls and the out ball passage for guiding out balls that have entered the out ball opening are also communicated with the storage chamber, and the balls (game balls) fired from the starting end are stored again. At the same time, the prize balls are stored in the prize ball case through another prize ball system, and when a safe ball enters the safe ball opening, the prize ball case is released under this condition. The game ball system and the prize ball system are separated and independent by being activated and discharged into the prize ball tray, and a ball exchange device for exchanging the game balls and the prize ball is provided between the storage chamber and the prize ball tray. When the prize ball guided from the prize ball tray is released outside the machine (outside the system) through the ball exchange device, the game ball corresponding to the passing ball is sent from the storage chamber to the starting end of the firing band, and the game ball is sent out of the system. The actual pachinko game is played using the game balls instead of the prize balls that are released.

The pachinko game machine according to this proposal uses two types of balls, game balls and prize balls, so that, for example, the game balls do not come into contact with the player's hands, so they do not become contaminated, and therefore the inside of the gaming section can be kept clean at all times. Since it is possible to prevent illegal balls from entering the game, it is possible to ensure a fair game at all times.
Furthermore, if the limited number of game balls enclosed in the machine is controlled, for example by controlling the ball diameter, a fair and stable game can be guaranteed. There are various advantages such as not having to manage all the balls used.

However, with this pachinko machine, if the prize balls and game balls are not continuously exchanged during play, the game is interrupted, so when the prize balls are stored in the prize ball tray and ready to be exchanged, It is necessary to keep the ball changing device in operation. For this reason, for example, if a game ball that has been fired due to a ball clogging in the game ball circulation system does not return to the storage chamber, and there is a shortage of balls to be exchanged for prize balls in the storage chamber, the ball replacement device Despite this operation, a problem arises in that the game ball corresponding to the passing prize ball is not supplied to the firing position (starting position), which may impede fair gaming.

In view of these points, the present invention, when there is a shortage of game balls to be replaced in the storage chamber, immediately stops the replacement work of the ball replacement device and always exchanges prize balls with prize balls based on a preset value relationship. It is an object of the present invention to provide a game stop device for a pachinko machine, which is characterized in that it guarantees the exchange of game balls and enables fair games. Hereinafter, the present invention will be explained based on illustrated embodiments.

Furthermore, on the front side of the game board 2, there is a guide rail 8' that is attached in a spiral shape following the firing band 8 and forms a game section on the board surface, and a guide rail 8' that is surrounded by this rail to prevent the ball from falling. Obstacles such as nails, windmills, etc. that may cause damage are provided, and a safe ball port is appropriately placed, and an out ball port 15 is provided at the lower end of the guide rail.

In the figure, 16 is a game ball storage chamber for storing game balls A, and 17 is a ball exchange device for exchanging the prize balls B received in the prize ball tray 13 with the game balls A. A prize ball transporting means 18 is provided in association with the prize ball transporting means, and the game ball is ejected from the storage chamber 16 by swinging as the prize ball moves through the prize ball transporting means. 8
This is a ball sending means for sending the ball to the starting end 8a of the ball.

The game ball storage chamber 16 is a board 1a that is fixedly provided in the lower part of the machine frame 1 (this board is located at the bottom of the game board when the game board 2 is fixedly provided with respect to the machine frame). ) is housed in a cavity formed by cutting out the firing band 8, and is provided in the vicinity of the firing band 8 in a forward downward slope, with its tip facing the starting end 8a and communicating therewith. .

A predetermined number of game balls A are stored in this storage chamber 16 in a line, and as will be described later, by the operation of the ball feeding means 18, the game balls A are moved one by one from the first game ball to the starting end 8a of the firing band. The game balls that have been sent out are guided by the shooting band 8 by the impact of the punch 5 at the shooting position 3 and are shot out to the game section.

The firing device 3 is of the same type as that used in conventional so-called electric pachinko gaming machines.
By rotating a handle (not shown), the winding piece 19 formed in a fan shape is turned to wind the wire 20 connected to the spring 4, thereby adjusting the elastic force of the punch and rod 5. The motor 6 is turned on, the cam 7 is rotated, the punch 5 biased by the spring 4 is released, and the ball supplied to the starting end 8a is fired. The game ball that has been played will enter either the safe ball hole provided in the gaming section or the out ball hole 15.

The balls that have entered the out ball opening 15 return to the game ball storage chamber through an out ball passage 21 that connects the ball opening and the rear end of the game ball storage chamber 16. On the other hand, the balls that have entered the safe ball opening enter the safe ball collection chamber 14 and are guided to the prize ball case 11 along its sloping bottom 22. After activating the prize ball case, the ball passes through the safe ball passage 23. In the same way as the out ball, it is returned to the game ball storage chamber 16 with which it communicates.

The prize ball case 11 is formed into a cylindrical shape that can accommodate a predetermined number of prize balls B, and has a support shaft 2 implanted in the substrate 1a.
4 as a fulcrum, and is always tilted upward in the front under the weight of the rear end side, with the front end opening 11a facing the lower end of the prize ball guiding gutter 10,
A certain number of prize balls transferred from this can be stored inside. A cam-shaped rotary wheel 25 rotated by a motor (not shown) is provided inside the safe ball passage 23 passing downward, and a swinging rod 26 is provided so as to be in contact with the upper surface of the rotary wheel.
is provided so as to swing freely about a support shaft 27 as a fulcrum.

The rotating wheel 25 receives the safe balls flowing from the safe ball collection chamber 14 into the safe ball passage 23 in its groove and rotates, and the rotating wheel 25 rotates by receiving the safe balls flowing into the safe ball passage 23 from the safe ball collection chamber 14.
The rod 2 hanging from the rear of the prize ball case 11 is pushed up using the support shaft 27 as a fulcrum by passing between the rods 2 and 6.
8 is pushed up to cause the prize ball case to fall forward and downward, and with this falling, a predetermined number of prize balls B stored inside are discharged into a prize ball discharge path 12 opening below. During this time, prize ball guiding gutter 10
A stopper 29 protruding from the top of the front end opening 11a of the prize ball case 11 prevents the prize ball from moving out of the ball case 11.
It will be blocked by. After the prize balls have been released, the prize ball case is restored to its original state by the weight of the rear end, and the prize balls are stored inside in preparation for the passage of the next safe ball.

Next, from this prize ball case 11, the prize ball ejection path 12
The prize balls ejected into the base board 1a escape to the front of the base plate 1a through a communication port 30 provided at the lower end, and are guided to a prize ball tray 13 attached to the front surface of the base board.

The prize ball tray 13 in this embodiment includes a guide groove 31 that slopes in one direction along the front edge of the bottom, and a downwardly sloped guide path 32 extends from the sloped lower end of the guide groove toward the substrate 1a side. , the opening at the tip thereof faces the lower end of the ball exchanger provided on the back surface of the substrate 1a.

In this embodiment, the prize ball transfer means 17 of the ball exchange device includes a pair of pulleys 33 and 34 that face each other vertically, and ball receiving pockets 35 arranged in a row at a required interval on the outer peripheral surface installed between the pulleys. It consists of an endless belt 36 and a guide rail 37 attached in parallel so as to surround the outside of this belt 36, and a cam rotated by the motor 6 of the firing device 3 is attached to the upper pulley 33. Pulley 3 of rotation axis of 7
A belt 39 that spans the motor 6 is attached to the motor 6.
The tensioned belt 36 is moved in conjunction with the rotation of the cam 7 by the drive of the cam 7.

A ball feeding device 18 that swings about a support shaft 40 is located above this prize ball transporting means 17,
Further, the upper end 37a where the guide rail 37 is cut faces a discharge path 41 for discharging the balls (prize balls) that have passed through the prize ball transfer device 17 to the outside of the machine.

The ball feeding device 18 is a rod-shaped swinging rod, and a spherical weight 42 is attached to the rear end facing directly above the prize ball transporting means 17.
is provided, and a protrusion 43 is provided on the other tip 18a.
This protrusion 43 is connected to the game ball storage chamber 16 by providing a
It is facing from below at the front end of.

This ball feeding device 18 normally has its rear end in contact with the outer peripheral surface of the belt 36 of the prize ball transporting means by means of a weight 42, and in this state, the protrusion 43 at the tip end
is inserted into the tip of the storage chamber 16 to prevent the game ball A from moving forward along the slope.

In this way, the prize ball transporting means 17 operates its belt 36 by driving the motor 6 as described above, and along with this movement, the balls guided from the guideway 32 (to the prize ball tray 13) a ball feeding means 1 that receives hot balls one after another into the pocket 35, raises the balls, and brings the balls into contact with the circumference one by one;
8, and push it up each time, and as it is pushed up, the push-up rod 4 at the tip
3 is moved up and down, and the storage chamber 16 is moved up and down by this up and down movement.
The game ball A inside is sent to the starting end 8a of the firing band 8. Note that a step is provided between the tip of the storage chamber 16 and the starting end 8a to prevent natural inflow, so that the particles can be fed one by one only by pushing up the pushing rod 43.

Therefore, the ball exchange device exchanges one prize ball B by the joint operation of the prize ball transport means 17 and the ball sending means 18.
When the ball passes through the prize ball transport means 17, the ball transport means 1
8 is swung once around the support shaft 40, and by thrusting up the protrusion 43, one game ball A is sent from the storage chamber 16 to the starting end of the firing band, and as the belt 36 moves, a prize is sent. While the prize ball B continues to be sent from the ball tray 13, this movement is continued, and one prize ball B and one game ball A are exchanged continuously. During this time, the cam 7 is rotated by the drive of the motor 6, and the punch 5 repeats the firing operation, so that the game balls A supplied to the starting end 8a are fired toward the gaming section. In this case, by synchronizing the batting motion of the pestle 5 in accordance with the exchange of the prize ball B and the game ball A, it becomes possible to fire the batted balls in accordance with the exchange of the prize ball and the game ball, and also to continuously fire the batted balls. Therefore, in the game machine of the present invention that uses two types of balls, prize balls and game balls, exactly the same game is played as in the conventional pachinko game machine that uses one type of ball.

In this way, the prize balls that have passed under the ball feeding device 18 by the belt 36 are then sent to the discharge path 41 and discharged outside the machine.

In the figure, 44 is a bypass passage connected to and branched off from the discharge passage 41, and 45 is a spare bulb chamber provided in this bypass passage.

This bypass passage 44 is a passage that preferentially receives prize balls that have been exchanged with game balls flowing down the discharge passage 41 (balls that have lost their value as prize balls in the game), and is provided in the middle of this passage. The spare ball room 45 contains a plurality of (three in the drawing) the above prize balls,
That is, the spare balls C are stored.

This spare ball is used to return a ball corresponding to the FAR ball to the player when the fired game ball A becomes a FAR ball.

In this embodiment, the Far ball opening 46 is provided at the joint between the tip of the firing band 8 and the guide rail 8', and the Far ball passage 47 is connected to the Far ball opening 46, and the Far ball passage is connected to the game ball. It communicates with the rear end of the storage chamber 16. and,
A rotary wheel 49 having ball receiving grooves 48 on its circumferential surface is provided in the middle of the Far ball passage 47, and an L-shaped detection rod 51 supported swingably on a support shaft 50 is mounted on the rotary wheel 49. are provided opposite to each other, and furthermore, a lifting rod 52 that projects into the preliminary ball chamber 45 is connected to one end of the detection rod 51.

The rotating wheel 49 and the detection rod 51 constitute a detection device that detects the Farr ball passing through the Farr ball passage 47, and the pulling rod 52 bypasses the spare ball C stored in the spare ball chamber 45 in conjunction with this detection. The ball is flowed into the passage 44 and returned to the prize ball tray 13 as a prize ball.

That is, if the game ball A fired by the operation of the firing device 3 returns without reaching the game section, or once it reaches the game section, the ball that is bounced back is returned to the game ball opening 46 as a FAR ball. enter,
The ball is returned to the storage chamber 16 through the Far ball passage 47. At this time, the ball returning through the Farr ball path is received by the groove 48 of the rotary wheel 49, and as the ball rotates, the spherical surface pushes away the circumferential detection rod 51, causing it to swing around the spindle 50. The lifting rod 52 is pulled up, and the spare balls C in the spare ball chamber 45 are lifted up one by one, allowed to climb over the step 53 that separates the spare ball chamber, and are returned to the prize ball tray 13 through the bypass passage 44. The rotary wheel 49 is rotated by a belt 54 stretched between it and the pulley 33 of the prize ball transfer device 17, so that it does not interfere with the passage of the FAR balls.

Therefore, from the above-mentioned configuration, in this pachinko machine, while the prize ball is in the prize ball tray 13, the prize ball is guided to the prize ball transfer means 17 which is rotated by the drive of the motor 6, and is guided by the movement of the belt 36. Accordingly, the discharge path 41
On the other hand, as the prize ball passes, the ball sending means 18 is activated, and the game ball stored in the game ball storage chamber 16 is sent to the starting end 8a, and the prize ball and the game ball are exchanged. Therefore, a pachinko game is played by firing the game balls that have been sent out, but in this case, the balls can actually be exchanged even if there are no game balls in the storage chamber 16. Since the ball is driven, the prize ball continues to be ejected, which impedes accurate exchange of the preset prize ball and the game ball.

In the figure, 54 is a detection means for detecting when a game ball A to be replaced is missing in the storage chamber 16, and 55 is installed in the power supply circuit of the motor 6 that drives the prize ball transfer means 18. The switch 56 is interlocking means inserted between the detection means 54 and the switch 55.

The detection means shown in this embodiment is a footplate supported swingably around a support shaft 57, and the rear end of the footplate 54 has a raised tip that projects into the storage chamber 16. A weight arm 54a for biasing is extended. This weight arm 54a has a weight that can be pushed up when one game ball is placed on the tip of the tread, and when there is a game ball on the top of the tread,
It is placed along the bottom surface of the bottom plate of the storage chamber.

On the other hand, the interlocking means 56 is an L-shaped rod whose bent center part is rotatably supported on a support shaft 58.
One end faces the lower surface of the weight arm 54a, and the other end faces the operating contact piece 55a of the switch 55, and is normally biased by a spring (not shown) that is compressed on the operating contact piece. One end of the above is attached to the weight arm 5
It is arranged to make contact with the lower surface of 4a. and,
In this state, set the above switch to ON,
The motor 6 is energized.

Therefore, when there are game balls in the storage chamber 16, the motor 6 that drives the prize ball transport means 17 is energized, so the prize balls from the prize ball tray are sent through the prize ball transport means, and during this time the ball transport means 18 is activated to send the game balls in the storage chamber to the starting terminal 8a, and exchange the prize balls with game balls correctly. When there is a shortage of balls, the treadle 54 jumps up under the action of the weight arm 54a and lowers the weight arm, which rotates the interlocking means 56 and presses the contact piece 55a of the switch 55 to cut the prize ball. By stopping the driving of the transfer means 17, it is possible to immediately stop the ball replacement operation.

As described above, the present invention is configured to automatically stop the replacement operation of the ball replacement device when there is a shortage of game balls waiting in the storage chamber. Even if you are in a position where the prize ball is supplied to the ball, it is possible to effectively avoid an unexpected situation where the prize ball simply passes and the game ball is not replaced with a game ball, resulting in a blank shot. You will be able to carry out the game below.

In addition, in the above embodiment, since the motor serving as the driving means of the ball exchange device is configured to also serve as the motor 6 of the firing device 3, in this embodiment, the firing operation stops at the same time as the exchanging operation stops, and the game stops. However, the drive motor for the ball changing device may be prepared separately without being connected to the motor of the firing device, and in this case, the above-mentioned switch 55 may be provided in the power supply circuit of the motor. It becomes possible to stop only the ball replacement work.

Further, in the embodiment, the detection means 54 is a step board, but as another implementation method, for example, a swinging detection rod may be inserted into the storage chamber and activated depending on the presence or absence of game balls, and this detection The driving of the associated motor may be controlled so that the rod and the movable contact piece of the switch are interlocked, and the ball exchange device may be stopped at the same time as the game ball runs out, but this is limited to one embodiment. isn't it.

Although all the enclosed game balls are stored in the storage chamber at the start of the game, the number of remaining balls sent to the game board decreases when the game starts, so the detection means is placed near the tip of the storage chamber. It is preferable to equip it according to the actual situation.
