(Conventional technology and its drawbacks) The prize ball ejecting device of pachinko machines is
As disclosed in Japanese Patent No. 33913, a ball passage connected to the downstream end of the supplementary ball guiding path and bent in a substantially U-shape is provided, and a stopper that allows free retraction movement is provided at the downstream end of the passage, and the ball On the side of the passage, a lever piece that always projects the ball stop protrusion into the ball passage is supported by the weight balance on both sides of the shaft, and a swinging member that swings for a very short time when a safe ball occurs. At the same time, the lower side surface of the lever piece is pressed to maintain the protrusion of the ball stopper projection into the ball passage, and at the same time, the stopper, which is released from the pressure by the swinging member, is retracted by the pressure of the ball in the ball passage, thereby locking the ball. After releasing the ball from the stopper to the stopper, the swing member presses the stopper to a position that closes the lower end of the ball passage, and the balls filled into the ball passage from the guide trough push the ball stopper to free the lever piece. Some devices have a structure in which a rocking motion is generated, and when a predetermined number of balls are filled, a return rocking motion is generated in which the ball stopper protrusion protrudes into the ball path due to the above-mentioned weight balance. However, in the above device, the weight balance of the lever piece must be determined so that the ball stop protrusion protrudes into the ball path, and when a safe ball occurs, the ball is stopped by the replenishing ball that flows down from the guide gutter. It is necessary to apply ball pressure to the stop protrusion to allow the lever piece to swing freely, and the lever piece has a special structure such as a ball stop protrusion protruding into the ball path for purposes other than free swing, and it requires replenishment. Since the lever piece is swung around the shaft when replenishing balls, it is necessary to shorten the length of the lever piece in the vertical direction to reduce the space required for swinging. As mentioned above, it is bent to match the height of the lever piece, and for this reason, the width of the ejection device has to be made relatively large within the width of the pachinko machine.
This method has drawbacks such as reducing the installation area for devices other than the ejection device provided on the back of the pachinko machine.

(Improvements of the Present Invention) In order to eliminate the drawbacks caused by the use of a swinging lever piece in the conventional prize ball discharging device, the present invention provides a device connected to the downstream end of the supplementary ball guiding path as described above. The ball passage provided as a vertical ball is provided with an actuating plate on the side that is pushed up when a safe ball occurs, and when the ball is not pushed up by the actuating plate, it swings to a position that does not impede the flow of balls in the ball passage. The support claw is pivotably supported, and the above-mentioned operating plate is pivoted by a parallel link, and as the operating plate pushes up against the spring elasticity, the parallel link moves upward while swinging, and this upward movement causes the engagement. The structure is such that the supporting claw is swung so that the toe protrudes from the supporting claw entry/exit hole into the ball passage, thereby interfering with the downward movement of the ball above the toe. Furthermore, the protrusion of the locking pawl into the ball passage is caused by the movement of the actuating plate as it rises, and even if the oscillating plate is provided with a spring that pulls it downward, A device that does not increase the load caused by pushing up the plate, and also allows the ball passage and the operating plate to be vertically parallel to each other, increasing the area for attaching members for other purposes on their sides. It is.

In this case, the first connecting piece 60 and the second connecting piece 61 are separately connected to the eccentric portion, and the second connecting piece 61 is connected to the connecting piece 57 of the stop plate 53.

The first stopper 2 is located on the back of the lower part of the case 11.
A lever 63 for removing a ball corresponding to the upper part of the second stopper 33 is attached by a shaft 62, and a lifting spring 69 is attached to the left side of the shaft 62 of the lever 63. The lever 63 is provided with a curved portion 64 that allows the swing prevention pin 46 to move upward, and further contacts the first contact edge 36 of the second stopper 33 from the right to prevent the second stopper surface 34 from moving unduly. A locking protrusion 65 is provided (see FIG. 8). Further, a restraining lever 66 corresponding to the first stopper 27 is pivotally supported on the shaft 26 of the second stopper 33 on the back surface of the case 11, and the lever 66 has a locking lever 66 that swings in the direction of the arrow in FIG. An engaging edge 67 that engages with the contact edge 30 of 27 is provided, and the lever 66 is connected to the connecting piece 6.
8 is connected to the free end of the ball extraction lever 63 to apply the elastic force of the pull-up spring 69.

A sensing piece 6 supported by a shaft 5 is attached to the bottom of the guide gutter 3, and a rotating plate 8 supported by an axis 7 is attached to the lower surface of the left side of its free end to the plywood plate 1. A rod 9 connected to the sensing piece 6 is axially connected to the plate 8 at an eccentric position, and the left end of the first connecting piece 60 is axially connected to the eccentric position of the interlocking plate 59.

In this embodiment, when the replenishment balls x flowing out from the ball tank 2 ride on the sensing piece 6 in the guide trough 3, the weight lowers the free end as shown in FIG. To rotate the interlocking plate 59 at an angle of , the first connecting piece 60 rotates the interlocking plate 59 in the direction of the arrow in FIG. from the upstream end 13 of the pipe as shown in FIG. Therefore, the supplementary balls x flowing down the guide gutter 3 are lined up vertically in the ball passage 12, excluding the receiving surface 54 of the inhibiting piece 49, and at the end 14, the first stopper surface 28 of the first stopper 27 and the second stopper 33 2nd stopper surface 3
Ride within the narrow space of 4 as shown in Figure 5. On the other hand, the first stopper 27 has its stop edge 31 in contact with the rocking prevention pin 46 of the actuating plate 37 in the lowered position, and is prevented from rotating clockwise, and the second stopper 33 has its first contact edge 36 in contact with the swing prevention pin 46 of the operating plate 37 in the lowered position, and the second stopper 33 has its first contact edge 36 connected to the ball removal lever. 63 locking protrusion 6
5 and is prevented from rotating counterclockwise, the lowest replenishment ball x in the ball passage 12 is held by the first stopper surface 28 and the second stopper surface 34,
The contact portions of the balls are aligned with the locking pawl entrance/exit holes 24.

When a safe ball occurs in a pachinko machine and flows out to the back of the machine, the projecting rod 45 is pushed up a little by the rotor 71 that causes a small angle of reversible rotation by the ball, or by the solenoid that closes the drive circuit by the ball. . At that time, the upstream end 13 of the ball passage 12
When the replenishment balls are filled up to
Since the notches 51 and 55 of the inhibiting piece 49 match the locking protrusion 47 of the actuating plate 37 as shown in FIGS. 1 and 2, the actuating plate 37 is rotated by the parallel links 38 and 38. As shown in FIG. 6, the locking claw 44 projects into the ball passage 12 from the locking claw entrance/exit hole 24 to prevent the supplementary ball x above the tip from flowing down.
On the other hand, while the actuating plate 37 is rising as described above, the swing prevention pin 46 moves upward together with the actuating plate 37, and the stopper surface 28 of the first stopper 27
As shown in FIG. 6, the stopper 27 rotates clockwise due to the weight of the refill ball x acting on the first stopper surface 28, and all of the refill balls x downstream of the tip of the locking claw 44 are removed. The prize ball release path 72
released into the The release is fast and the actuating plate 3
7 rises for a short period of time and then ends when the first stopper 27 is about to move down.
Returning to the angle shown in the figure, the swing prevention pin 46 lowers and engages with the stop edge 31 just before the locking pawl 44 retreats its toe into the locking pawl entrance/exit hole 24 due to the lowering of the operating plate 37. Immediately after that, the locking pawl 44 is connected to the entrance/exit hole 2.
4 and loses the locking effect of the toe on the upstream replenishment ball x, so the replenishment ball x again descends until it hits the first and second stopper surfaces 28, 34, and as a result of the above, the prize ball is released. Then, the replenishment of the ball passage 12 is completed. When the supplementary balls x riding on the sensing piece 6 of the guide gutter 3 run out, the receiving surface 54 of the stop plate 53 advances into the upstream end 13 of the ball passage 12 as shown by the chain line in FIG. 2, and the first connecting piece 60 , the sensing piece 6 is flipped up via the interlocking plate 59 and the second connecting piece 61, and the notch 55 is rotated to move the abutting edge 56 to the locking protrusion 4 of the actuating plate 37.
7 to correspond to the above. As described above, when the receiving surface 54 protrudes into the upstream end 13, the replenishing ball x flows from the upstream end 13 into the ball passage 12, and even if a safe ball occurs, the actuating plate 37 is moved against the abutting edge 56. Since the locking protrusion 47 is struck and does not substantially rise, the swing prevention pin 46 remains engaged with the stop edge 31 of the first stopper 27, and the ejection of the prize ball is interrupted.

When there are no balls in the ball passage 12, the upward movement prohibition piece 49
Due to its weight balance, the receiving surface 50 is advanced into the ball passage 12, and at the same time, the abutment edge 52 is moved toward the actuating plate 3.
The upward movement of the actuating plate 37 is restrained by contacting the locking protrusion 47 of No. 7, thereby preventing the ejecting operation of the prize ball.

When the end of the ball removal lever 63 is momentarily lifted with a solenoid or hand, etc. at the end of the work day, the first contact edge 36 of the second stopper 33 comes off the locking edge 67, and the second stopper The weight of the replenishment ball x acting on the stopper surface 34 causes it to rotate counterclockwise as shown by the arrow in FIG. 73. At that time, the restraint lever 66 is
8, the engagement edge 67 is brought into contact with the contact edge 30 of the first stopper 27 as shown in FIG. 8, thereby preventing clockwise rotation of the stopper 27 and protecting the swing prevention pin 46. . Even if the ball removal lever 63 is released from its lifting position during ball removal, the elastic force of the pull-up spring 69 causes the locking protrusion 65 to come into contact with the second contact edge 36a as shown in FIG. will not rotate clockwise under its own weight and return. After removing the ball, press the lever 63 for removing the ball.
When you lift it again, it will automatically move to the first stopper surface 28.
Perform a return rotation to make it vertical.

The other part 74 is a ball that is manually tilted in the direction of the arrow in FIG. This is a stop lever.

(Effects of the present invention) The present invention has the structure and operation made clear by the description of the embodiments described above, and the ball passage 12 provided connected to the downstream end of the supplementary ball guide path 3 has a vertical shape without bending. Therefore, the actuation plate 37 provided along one side wall of the ball passage is also vertically parallel, and the ball passage 12 and the actuation plate 3 constituting the prize ball discharging device of the present invention are
7 in the width direction of the pachinko machine, the width of the mounting area for devices other than the ejection device provided outside the ejection device can be relatively increased. Furthermore, since the actuating plate 37 is attached to the parallel link 38 and moves both vertically and under the swing of the link, the plate 37
In addition to solving the configuration related to the installation of the safe ball, the force of pushing up by the member that acts on the actuating plate 37 in connection with the generation of the safe ball can be prevented even if a spring elasticity is applied to the actuating plate 37 to resist the pushing up force. The upward movement of the operating plate 37 and the locking claw 4 are converted into a force that swings the parallel link 38 via the plate 37.
No delay is caused in the rocking of 4. Furthermore, the locking pawl 44 that is pivotally supported on the operating plate 37 is operated by hooking its toe to the bottom of the locking pawl entrance/exit hole 24 on one side wall of the ball passage 12 both when a safe ball is generated and when a safe ball is generated. When the plate 37 rises, the toe protrudes into the ball path,
Other than that, the movement of the ball in the ball passage 12 is moved to a position where it does not interfere with the movement of the ball, and although the locking pawl 44 is pivotally supported by the actuation plate 37, the entire weight is not applied to the actuation plate 37. This has various effects such as making the entire operation of releasing the prize ball related to the generation of the safe ball and the return of the operating plate 37 etc. easier.
