DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guiding gutter for guiding balls in a reserve tank in two rows, a ball discharging device connected to the guiding gutter and capable of discharging a required number of balls, and a ball discharging device. TECHNICAL FIELD The present invention relates to a ball game machine having a discharge gutter for guiding a ball discharged from a ball, and more particularly to a structure of a ball discharge device.

[0002]

2. Description of the Related Art As is well known, for example, a pachinko game machine as a ball game machine, when a player hits a ball into a game board one by one by a firing device provided at a lower portion of the game board, the ball hits an obstacle nail. A predetermined number of prize balls are given to the player by entering the prize area with a probability of falling while changing the direction at random. Conventionally, such a prize ball is paid out by a mechanical prize ball discharge device, for example, as shown in FIG. 1, which is generally mounted on the back of a game board and operated by transmitting a physical force generated by the prize ball. Had to be done.

[0003] That is, the back mechanism 220 in the conventional pachinko game machine has a structure that is attached to the back of the game board entirely and in a plane, and a reserve ball storage tank 224 is provided above the back mechanism 220. A ball chute 22 which is arranged continuously and flows down and aligns while making a spare ball U-turn in an S shape.
5 are provided independently, a ball drain gutter 231 is externally assembled in the lower part of the ball chute 225, and a prize ball payout mechanism and a prize ball collecting gutter 221 are provided in the center of the back surface of the game board. A controller 260 that stocks the winning balls and separates and flows them one by one, and an operating lever 265 that is rotated by the weight of the separated winning balls and faces the winning ball discharge gutter 222 is provided. The physical force generated by the winning ball through the interlocking rod 266 and the link mechanism 267 connected to the
Is transmitted to a prize ball case 268 provided at the end of the prize ball, and is operated to discharge a predetermined number of prize balls onto a damper 269 disposed thereunder, and further flow down a prize ball discharge path 236. The prize ball was discharged to the saucer on the front. Then, in the central part of the back mechanism 220, an out hole 2 for accommodating an out ball that could not be won anywhere.
19 and an out ball gutter 223 were provided, and were discharged outside the machine.

[0004] Therefore, in the conventional pachinko game machine, the mechanical structure of the back mechanism 220 provided on the back of the game board becomes complicated, assembling and positioning adjustment are troublesome, and the occupied space of the components of the back mechanism 220 is increased. It becomes too large to have enough space on the back of the game board. In other words, the effective use space at the back of the game board becomes narrow, and the storage tank 2
The inflow path of the extra balls such as the reserve balls, the winning balls, and the out balls in the machine 24 must be complicated, and there is a problem that the balls are easily clogged and the clogging is difficult to be seen from the outside. There was an inconvenience that maintenance and inspection of the back mechanism panel became difficult. On the other hand, in recent pachinko machines, those having an auxiliary game device that creates a state in which a large number of prize balls are given, called a lucky seven, and a large variable prize device using an electric drive source are popular among gamers. Most of the models are equipped with a large variable winning device and an auxiliary game device. However, such large floating prize devices and auxiliary game devices,
In many cases, the electric drive source extends through the game board and extends to the rear of the back-side set board. Therefore, with the back mechanism of the conventional configuration, such a variable prize winning device and an auxiliary game device are extended. There is a disadvantage that sufficient space cannot be obtained.

[0005]

Further, with the use of the above-mentioned auxiliary game device and large-size variable winning device, the chances of simultaneously or successive winning balls being extremely increased.
However, in the conventional mechanical prize ball dispensing mechanism, the discharging operation requires about 1.5 seconds for one dispensing cycle due to the mechanical link motion as described above. A hit ball addressed is fired. That is, since the hit ball is launched into the game basin every 0.6 seconds, a large amount of winning balls are generated in a short time, and the discharge of the prize balls may not catch up, and the winning balls may be accumulated one after another. Therefore, a high-speed prize ball dispensing device is demanded, and a large amount of prize balls are dispensed to the player with the device, so that the flow of the prize ball is smoothed, the discharge of the prize ball is stabilized, and the prize ball discharging device is provided. There is a need for structural reinforcement in itself. Conventionally, in particular, the applicant of the present invention has
In a structure in which a sprocket is rotatably faced to a vertical guiding gutter as proposed in Japanese Patent Publication No. 879 or the like, a prize ball flowing down the guiding gutter by a small amount of down pressure of the prize ball bites the sprocket. In addition to the occurrence of the ball biting state, the rotation speed of the sprocket itself changes due to the falling pressure of the prize ball, so that the ball cannot be discharged stably at high speed.

Further, with the speeding up of the prize ball discharge device and the increase in the number of discharges as described above, a prize ball discharge device capable of sufficiently withstanding frequent discharge operations is desired. The conventional mechanical discharge device operated by the transmission of the physical force generated by the above has a limit in increasing the speed due to abrasion of each mechanism and the like, and has poor durability. In addition, with conventional pachinko machines equipped with a mechanical discharge device, the operation becomes inoperable due to the friction and deformation of each part, and the so-called clogging of balls occurs due to the entry of foreign matter into the winning ball case or the misalignment of the balls, resulting in discharge. There has been a weak point that the discharge operation is inaccurate and uncertain due to troubles such as stoppage of functions and defective discharge. An object of the present invention is to provide a large number of prize balls in a short time by using an induction trough in which prize balls flow down in two rows and an electric prize ball discharge device so as to correspond to a so-called lucky seven pachinko game machine or the like. It is an object of the present invention to perform payout and reduce the flowing pressure of the prize ball with a relatively simple structure so that the prize ball can be rapidly and stably paid out. Further, another object of the present invention is to provide an arbitrary number of balls even if the number of paid out prize balls becomes odd or even with the diversification of game contents, and one ball can be sent to one ball. It is to ensure that the required number of prize balls can be paid out by counting sequentially.

[0007]

SUMMARY OF THE INVENTION The present invention has been made under the above-mentioned background, and has a guiding gutter (guiding path 25) for guiding balls in a spare tank (preliminary storing portion 24) in two rows.
A ball discharge device (prize ball discharge device 40) connected to the guide gutter and capable of discharging a required number of balls, and a discharge gutter (44) for guiding the balls discharged from the ball discharge device. In the ball-and-ball game machine (1), the ball discharging device includes a detecting means (for example, discharged ball detectors 45a to 45d) for counting a required number of balls discharged from the ball discharging device, and the guiding gutter. And a discharge separating gutter (for example, a sprocket 42) for separating one ball at a predetermined interval from each of the balls flowing down the guide gutter in two rows and provided at a position corresponding to the rotation separating member. A holding member (e.g., the blocking plate 4) for holding the sphere separated by the rotation separating member in a predetermined state.
3) a ball separating means, and an electric drive source (for example, a motor 41) for rotating the rotation separating member in a predetermined direction.
The rotation separating member is constituted by a single rotating body, and a moving engaging portion (for example, the concave portion 42a, The claw portion 42b) is formed, and when the rotation separating member is rotated, the balls received in two rows by the cooperative action of the moving engagement portion and the holding member flow down the ball of the guide gutter. The ball is moved in a direction substantially perpendicular to the direction and moved, and the discharge state of the sphere is alternately generated in each row of the guide gutter,
The discharging state of the sphere is detected by the detecting means.

[0008]

A ball discharge device which is driven by an electric drive source is provided between a guiding gutter for guiding the balls flowing down in two rows and a discharge gutter for guiding the discharged balls. When the dynamic separating member is rotated by the electric drive source, the balls flowing down the guide gutter in two rows can be reliably separated at predetermined intervals one by one. Then, by the cooperative action of the moving engagement portion and the holding member formed on the rotation separating member, the balls received in the two rows can be converted and moved in a direction substantially perpendicular to the ball flowing direction of the guide gutter. Then, by converting the ball to a substantially right angle direction, the downward pressure applied to the rotating separation member side from the ball downward direction of the guide gutter by the continuously flowing ball is received by the holding member, and the downward pressure during the movement of the ball Can be reduced. Therefore, the rotation of the rotation separating member becomes smooth, so that the occurrence of the ball biting or the ball stopping can be suppressed, and the separation and movement can be surely performed one by one at a predetermined interval. In addition, the detecting means detects a discharge state in which the balls received by the moving engagement portion are alternately discharged from the two rows of the guide gutters with the rotation of the rotation separating member, so that discharge of an arbitrary number of balls can be performed. It can be done reliably.

In this manner, the separating action caused by the rotation of the sprocket 42, the exhaust is taken out alternately prize balls one by one that are aligned with the outlet portion 25c ₁ and 25c within ₂ trough 44
It is discharged to. As described above, the sphere flowing down from the guiding path 25 is converted in a direction substantially perpendicular to the sphere flowing direction and moved, so that the sphere flowing continuously through the guiding path 2
5 is received by the cooperative action of the concave portion 42a, the claw portion 42b (moving engagement portion), and the blocking plate 43 (holding member) from the ball falling direction to the sprocket 42 side. Can be reduced. Therefore, the rotation of the sprocket 42 becomes smooth, and the occurrence of the ball biting or the ball stopping can be suppressed.
Separation and movement can be reliably performed at a predetermined interval for each individual.

Further, an L-shaped notch is formed in the blocking plate 43. As shown in FIG. 10, the notched plate 43 has a plurality of sensors 45a to 45d as discharge ball detectors as detecting means. 45 are provided. Of the sensors 45a to 45d, 45a and 45b are provided at the outlet 25c.
Sensors 45c and 45d detect whether or not there is a ball to be ejected next within ₁ and 25c _2. Sensors 45c and 45d are for checking whether or not the ball has been ejected. Can be used. When the winning detection signal output from the winning ball detector 55 is supplied to the control device 50, the prize ball discharging device 40 controls the control device 5

1 to start discharging. At this time, the control device 5
0 indicates that a drive command signal is generated after confirming that a spare ball is present at the exit of the taxiway 25 based on a detection signal from the discharged ball detector 45, and is output from the discharged ball detector 45 for each prize ball. In response to the received discharge confirmation signal, the discharge state is detected, it is determined that the number of prize balls has reached a predetermined number, and a discharge end signal is output to the prize ball discharge device 40 so that the rotation of the pulse motor 41 is stopped. Has become. As described above, the sensor 45 as a detecting means detects the discharge state in which the balls received by the sprocket 42 are alternately discharged from the two rows of the guide path 25.
By detecting a to 45d, it is possible to reliably discharge an arbitrary number of balls.

FIG. 13 is a block diagram showing an example of a control system of the prize ball discharging device 40 by the control device 50. A prize detection signal (pulse) generated from the prize ball detector 55 corresponding to each prize ball is supplied to a storage circuit 51 as a storage means such as a counter, and counted to store the number of prize balls. Is done. Further, a detection signal from a discharged ball detector 45 in the prize ball discharging device 40 is input to a control circuit 52 including a microcomputer (CPU) or the like, and the stored value of the storage circuit 51 is “1”.
Then, a drive command signal for driving the motor 41 of the prize ball discharging device 40 is output. Then, the motor 41 rotates to start discharging the prize balls, and a detection signal (pulse) is sent from the detector 45 to the control circuit 52 for each prize ball. The control circuit 52 counts the detection signal by, for example, an internal counter, and when the count value reaches a value preset in an internal setting device, determines that a predetermined number of prize balls have been discharged, and terminates discharge. Output a signal,
Alternatively, the output of the motor drive signal is stopped to end the discharge.

When the discharged ball detector 45 detects that no balls are discharged to the outlets 25c ₁ and 25c ₂ at the end of the guide path 25 due to clogging or the like during discharging, the discharged ball detector 45 detects that no ball is discharged. Upon receiving the output, the control circuit 52 immediately stops the motor 41, keeps the value of the counter as it is, and operates the motor 41 again when a prize ball enters the outlets 25c ₁ and 25c ₂ to operate the remaining prizes. Eject the ball. When one discharge is completed, the control circuit 52 sends a signal to the storage circuit 51 to decrement (decrease) the stored contents.
Let it. The control circuit 52 receives a signal from the ball shortage detector 56. When the detection signal is sent to the control circuit 52 due to the absence of the reserve ball in the reserve storage section 24, the drive of the motor 41 is performed. May be stopped, and the discharge of the prize ball may be stopped.

In this case, even if the ejection of the prize balls is stopped, the number of winning balls is held in the storage circuit 51, and if there is a new winning during that time, it is detected, counted up and stored. Then, when replenishment of the spare balls to the spare storage unit 24 is performed, it is preferable that the discharge of the prize balls is started again by the control signal from the control circuit 52. On the other hand, the control circuit 52
Is used to monitor a ball flow abnormality based on a signal from a flow abnormality detector 57 provided in the middle of the guideway 25 where dust and foreign matter easily enter and cause ball clogging, and when an abnormal signal comes in, The discharge device 40 is stopped. The flow-down abnormality detector 57 is provided for each row of the reserve spheres flowing down in the guide path 25 in two rows.

In the above embodiment, an arbitrary number of prize balls can be paid out at one time by changing the set value of the setting device in the control circuit 52. In addition, a plurality of setting devices in the control circuit 52 of the above embodiment are provided to set different values, and a prize detector is provided for each of the prize regions 15 to 18 so that the types of prizes are stored in the storage circuit 51 separately. It is also possible to change the number of prize balls discharged according to the type of winning. Further, in the above-described embodiment, the sprocket 42 having the concave portion and the claw portion on the peripheral surface is used as the rotation separating member of the prize ball discharging device 40, but instead of the sprocket 42, the spherical surface or the peripheral portion has a ball. As long as it is a rotating body having the moving engagement portion, a screw type or another configuration may be used. Further, in the present embodiment, the prize ball discharge device 40 has been described as a ball discharge device configured to discharge a prize ball using an electric drive source such as a pulse motor 41, but the present invention is not limited to this. Instead, a commonly used electric motor may be used.

As described above, according to the present invention, the rotation separating member of the ball discharging device is constituted by a single rotating body, and the ball received from the guiding gutter can be moved on the outer periphery thereof. A moving engagement portion is formed, and when the rotation separating member is rotated, the balls received in two rows by the cooperative action of the moving engagement portion and the holding member are moved in the ball flowing direction of the guiding gutter. The ball is ejected in a direction substantially perpendicular to the ball, and the ball is ejected alternately in each row, and the ejected state is detected by the detecting means. Therefore, the structure of the ball ejecting device itself is relatively simple. Can be

Further, the downward pressure applied to the rotation separating member from the ball flowing down direction of the guiding gutter by the ball continuously flowing down the guiding gutter is also received by the holding member, and the flowing pressure in the moving direction of the ball is reduced. As a result, a smooth and high-speed rotation of the rotation separating member can be obtained, and the rotation separating members can be reliably separated at predetermined intervals one by one without causing ball catching or ball stopping. The speed of discharge can be increased.

Further, since the discharge state of alternately discharging the balls received by the rotation separating member is detected by the detecting means, it is easy to discharge an arbitrary number of prize balls which can correspond to recent diversified game contents. In addition, the number of prize balls discharged can be made accurate and reliable, and the reliability can be improved.
