Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a ball-biting prevention device in the winning device of a pachinko machine, and in particular, it uses a rotary disk provided with a plurality of recesses of different depths, which can be freely rotated on a case plate. At the same time, winning ball distribution ports are opened at depths corresponding to the recesses of the case plate, and balls that enter each of the recesses are made to flow out from the winning ball distribution ports having the same depth. This invention relates to a ball-biting prevention device for a winning machine.

<Prior Art> As is well known, a rotary disk rotated by a motor is pivotally mounted on a case plate, and the rotary disk is provided with a plurality of recesses having openings on the side circumferential surface and having different depths from the circumferential edge.
In addition, winning ball distribution ports are provided on the case plate corresponding to the depth positions of the recessed holes, and the balls that enter each of the recessed holes are made to flow out from the winning ball distribution ports that have the same depth as the recessed holes. A winning device that distributes balls is known, for example, from Japanese Patent Publication No. 45533/1983.

<Problems to be solved by the invention> However, in the above-mentioned type of winning device, the rotary disk is constantly rotated by a motor during pachinko play, and the balls that fly into the winning hole are surrounded by guide pieces. When the ball path communicates with one of the recesses that has been guided above the side peripheral surface of the rotary disk and rotated upward, the ball retracts into the recess. Therefore, depending on the timing at which the ball falls from the ball path, the ball may often become caught between the lower edge of the guide piece on the front side in the direction of rotation and the upper edge of the side wall of the recess on the rear side in the direction of rotation. .

If the ball gets caught as described above, the rotating disk will stop and the game will have to be interrupted, and an abnormal load will be applied to the motor, which is the drive source, so there is a risk of damaging the internal gears, etc.

<Means for Solving the Problems> The present invention was proposed in view of the above, in which a rotary disk provided with a plurality of recesses of different depths is rotatably attached to a case plate, and the case plate is provided with recesses. In a winning device in which a winning ball distribution port is opened at a depth corresponding to the depth of the winning ball distribution port, and balls that enter the concave recess are made to flow out from the winning ball distribution port having the same depth, the winning hole is opened on the case plate At the same time, a ball passage is connected to the winning hole so that the lower end of the ball passage faces above the side circumference of the rotary disk, and a stopper member is made to face the ball passage to stop the ball from falling. At the same time, the stopper member and the drive source of the rotary disk are linked via an operating mechanism so that the operation of the stopper member is synchronized with the rotation of the rotary disk.

<Operation> Since the stopper member facing the ball passage is connected to the drive source of the rotary disk through the operating mechanism, the stopper member operates in synchronization with the rotation of the rotary disk, and the stopper member closes the ball passage, To temporarily prevent a ball from entering a recess provided in a rotary disk from a ball passage.

<Embodiments> The present invention will be described below with reference to embodiments of the drawings.

1 to 7 show a first embodiment of the present invention, in which the winning device 1 includes a case plate 2
and a rotary disk 3 rotatably pivoted to the case plate 2.

The case plate 2 has a circular accommodating part 4 that is open at the front and protrudes rearward, and a flange 5 that extends to the periphery of the accommodating part 4. A prize opening 6 is provided which projects forward and opens upward.

A rotatable rotary disk 3 is housed in the housing section 4, and a transparent cover material 7 is attached to the front surface of the housing section 4 by fastening means such as screws so that the rotary disk 3 inside can be seen through. . According to the illustrated embodiment, the cylindrical shaft portion 9 provided on the rotary disk 3 is loosely fitted into the fixing pin 8 which is insert-molded rearward in the center of the transparent cover material 7, and the cylindrical shaft portion 9 provided on the rotary disk 3 is loosely fitted into the fixing pin 8 which is insert-molded backward in the center of the transparent cover material 7. By inserting the shaft portion 9 of the rotary disk 3 into a bearing portion 10 provided in the rotary disk 3, the rotary disk 3 is rotatably supported with respect to the case plate 2.

A drive shaft 11 connected to a motor or the like as a drive source is fitted onto the shaft portion 9 of the rotary disk 3, and the driving force from the drive source is transmitted to the rotary disk 3.

The rotary disk 3 is provided with a plurality of concave recesses 12 that are open on the side peripheral surface and concave toward the center. The width of each concave recess 12 is constant and slightly wider than the diameter of the ball so that the ball can fall into it, but the depth is different and there are at least two types of depths. That is,
The rotary disk 3 of the illustrated embodiment has six radial recesses 12, of which two recesses 12a are deep and the other four recesses 12b are shallow.

On the rear wall of the accommodating portion 4 of the case plate 2, there are two winning ball distribution holes 1 corresponding to the depth positions of each of the recesses 12.
3 will be established. That is, the first winning ball sorting hole 13a corresponding to the deep concave hole 12a and the shallow concave hole 12b.
A second winning ball distribution opening 13b corresponding to the recessed opening 12a and 12b is provided so that the balls recessed into the respective concave recesses 12a and 12b flow out to the rear of the case plate 2 from the winning ball distribution opening 13 having the same depth. . And in the illustrated embodiment:
Since the probability of balls flowing into the first winning ball distribution port 13a is lower than that of the second winning ball distribution port 13b,
This first winning ball distribution port 13a is set as a winning ball distribution port.

A ball passage 15 surrounded by a guide piece 14 is communicated with the entry prize opening 6 provided in the case plate 2, and the lower end of the ball passage 15 is made to face a communication opening 16 opened in the upper wall 4' of the accommodating part 4. Therefore, when a hit ball flowing down the game board surface enters the prize opening 6 provided in the case plate 2, the hit ball passes through the ball passage 15 and enters the concave recess 12 of the rotating board 3 from the communication port 16. Become.

By the way, in the present invention, the winning device 1 as described above is
In this case, a stopper member 17 that can stop the ball falling through the ball path 15 is provided so as to operate in synchronization with the rotation of the rotary disk 3.

The stopper member 17 has a lever-shaped base plate portion 18 loosely engaged with the drive shaft 11 of the rotary disk 3, and a stopper piece 19 extending outward from the outer end of the base plate portion 18. The piece 19 faces above the concave recess 12 through a slit 20 provided in the lower part of the ball passage 15.

However, if the stopper member 17 remains as it is,
Even if the ball enters the winning hole 6 and falls down the ball path 15, the ball will not fall into the concave hole 12 of the rotary disk 3, so the stopper member 17 is swung at a desired timing to open the communication hole 16. Must be opened and closed.
Therefore, the opening/closing operation of the stopper member 17 and the rotation of the rotary disk 3 are synchronized via the operating mechanism 21.
That is, in the illustrated embodiment, the actuation mechanism 21 includes:
A swing shaft 25 is provided with a fan-shaped gear portion 22 at the base end of the base plate portion 18 of the stopper member 17, and a crank-shaped interlocking member 24 having a tooth portion 23 that meshes with the gear portion 22 is provided on the rear surface of the case plate 2. A receiving claw portion 26 is provided at the outer end of one arm portion 24a of the interlocking member 24, and a receiving claw portion 26 is provided at the outer end of one arm portion 24a of the interlocking member 24.
A spring hook 27 is provided at the outer end of the case plate 4b, and a coil spring 29 is stretched between the spring hook 27 and a pin 28 provided on the rear surface of the case plate 2. The spring 29 urges the stopper member 17 so that the stopper piece 19 closes the communication port 16.

A claw portion 30 is provided on the back surface of the rotary disk 3, extending from the side edge of each recess 12 along the outer peripheral edge of the rotary disk 3. The pawl receiving portion 26 of the interlocking member 24 described above comes into contact with this pawl portion 30. At the tip of the claw portion 30, an inclined abutment surface 31 having a receding angle is provided so that the receiving claw portion 26 can easily escape.

When the rotary disk 3 is rotated by the drive of a motor (not shown), the tip of the claw portion 30 comes into contact with the rear surface of the claw receiving portion 26 of the interlocking member 24, and when the rotary disk 3 further rotates, the interlocking member 24 is moved by the spring 29. The interlocking member 24 swings in the same direction as the rotary disk 3 about the swing shaft 25 as a fulcrum. At this time, the interlocking member 24 has a toothed portion 23, and the toothed portion 23 and the gear portion 22 of the stopper member 17 are engaged with each other.
The stopper member 17 swings about the drive shaft 11 in a direction opposite to the rotary disk 3 to open the communication port 16. When the rotary disk 3 continues to rotate further, the receiving pawl portion 26 of the interlocking member 24 comes off from the inclined contact surface 31 of the pawl portion 30, and the interlocking member 24 uses the swing shaft 25 as a fulcrum due to the bias of the spring 29. and rotate back. At this time, the stopper member 17 that engages with the interlocking member 24 rotates back to close the communication port 16 again.

In the winning device 1 configured as described above, when a ball hits the winning hole 6, the stopper member 17
When the ball enters at the timing when the communication port 16 is closed, the ball temporarily stops on the upper surface of the stopper member 17. Then, when the rotary disk 3 further rotates and the stopper member 17 swings to open the communication port 16,
The ball rests on the side circumferential surface of the rotary disk 3, and when further rotated, falls into the concave recess 12, so that ball biting does not occur.

The timing at which the stopper member 17 rotates and the timing at which the concave recess 12 of the rotary disk 3 rotates directly below the communication port 16 can be easily determined by appropriately changing the shape of the claw member, gear ratio, etc. can be adjusted to Further, the timing at which the stopper member 17 closes the communication port 16 can be set after the communication port 16 and the concave recess 12 of the rotary disk 3 are aligned.

The ball enters the winning hole 6, passes through the ball passage 15, enters the concave recess 12 of the rotating disk 3 from the communication port 16, rotates together with the rotating disk 3, and passes through the first winning ball distribution port 1.
3a or the second winning ball sorting opening 13b, the winning ball sorting opening 13 having the same depth is discharged to the back of the case plate 2, and is detected by a detection switch (not shown), and other players are ejected based on this detection signal. It is possible to transfer to the game of Furthermore, the player can visually check the indentation state of the ball through the transparent cover material 7 attached to the front surface of the rotary disk 3, which increases the interest of the game.

8 to 11 show another embodiment of the present invention, in which an operating mechanism 21 for linking the rotation of the rotary disk 3 to the stopper member 17 is provided at the center of the back side of the rotary disk 3. It consists of a cam piece 32 that projects radially from the shaft portion 9, and a stopper member 17 whose end portion is pivoted to the case plate 2.

That is, a cam piece 32 that projects radially is provided near the rear end of the shaft portion 9 that projects toward the back side of the rotary disk 3.
The number of cam pieces 32 corresponds to the number of recesses 12, and six cam pieces 32 are provided in the illustrated embodiment. Further, each cam piece 32 is formed into a substantially trapezoidal shape.

Stopper member 17 that comes into contact with the cam piece 32
has a fan-shaped base plate 33 with a relatively narrow central angle, and a narrow portion of the base plate 33 is swingably attached to a support shaft 34 protruding from the back side of the case plate 2. A stopper piece 19 is provided at the outer end of the base plate 33 and extends through a slit 20 formed in the case plate 2 to face the upper side of the rotary disk 3.
The concave opening 12 of the rotary disk 3 can be closed. Further, a spring 29 or the like is stretched between the stopper member 17 and a pin 28 provided on the case plate 2, and normally urges the stopper piece 19 to close the lower end of the ball passage 15.

When the rotary disk 3 is rotated by the motor (counterclockwise in FIG. 9), the lower end 1 of the stopper member 17 is attached to the oblique side 32a of the cam piece 32 in the rotation direction.
7' abuts against each other and when the rotary disk 3 further rotates, the cam piece 32 also rotates together, so the oblique side 32a of the cam piece 32 presses the lower end 17' of the stopper member 17, and the stopper member 17 It rotates clockwise in FIG. 9 using the fulcrum as the fulcrum. Therefore,
Stopper piece 1 that closed the lower end of the ball passage 15
9 rotates to reach the lower end of the ball passage 15, that is, the communication port 16
(state shown by the chain line in Figure 9).

At this time, if the ball that entered the winning hole 6 on the top surface of the stopper piece 19 falls, this ball passes through the communication hole 16 and lands on the side surface of the rotary disk 3, and the concave hole 12 is rotated. When it arrives, it falls into this recess 12. The ball that has fallen into the concave recess 12 rotates together with the rotary disk 3, and is sent to the case plate 2 from the winning ball sorting hole 13 whose depth matches the first winning ball sorting hole 13a or the second winning ball sorting hole 13. The game is discharged to the back and detected by a detection switch (not shown), and based on this detection signal, it is possible to proceed to another game.

On the other hand, as the rotary disk 3 rotates further, the lower end 17' of the stopper member 17 reaches the apex 32 of the cam piece 32.
When passing point b, the lower end of the stopper member 17 disengages from the oblique side 32c of the cam piece 32 and is rapidly rotated back by the pulling force of the spring 29 to close the lower end of the ball passage 15 again.

Also in this embodiment, when the ball falls from the ball passage 15 into the concave recess 12 of the rotary disk 3, the ball does not get caught. Further, since the rotation of the rotary disk 3 is not stopped, no abnormal load is applied to the motor, and there is no risk of damage to the motor.

It should be noted that the reference numerals not explained in the embodiment shown in FIGS. 8 to 11 described above have the same construction as the same reference numerals in the embodiment shown in FIGS. 1 to 7 described above, and therefore the explanation thereof will be omitted.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments described above, and can be implemented as appropriate as long as the structure described in the claims for utility model registration is not changed. For example, the actuation mechanism may have other configurations as long as it can obtain power from the drive source of the rotary disk and can operate in synchronization with the rotation of the rotary disk.

<Effects of the invention> In summary, the present invention provides a prize opening in the case plate, a ball passage connected to the prize opening, and a lower end of the ball passage facing above the side circumference of the rotary disk. A stopper member faces the ball path to stop the ball from falling, and the stopper member and the drive source of the rotary disk are linked via an actuation mechanism, so that the operation of the stopper member is synchronized with the rotation of the rotary disk. As a result, the ball does not fall into the recess at the timing when ball biting occurs, and the ball does not get caught between the ball passage and the recess of the rotary plate. Therefore,
You don't have to interrupt your pachinko game and lose your interest.
Furthermore, since the timing of the operation of the stopper member 17 is synchronized with the rotation of the rotary disk, there is no timing deviation. Furthermore, since the power in the closing direction of the stopper member is derived from the traction force of the spring, it is independent of the motor that is the power source of the rotary disk.
Even if ball jamming occurs between the stopper member and the ball passage, no abnormal load is applied to the motor, and the durability of the motor is improved.
