As shown in FIG. 3, the ball discharging device 4A has two types.
Between the two plates 8L and 8R, there are two rows of ball passages 9 in the upper row.
A case gutter 9x consisting of a and 9b has a ball cutting passage 9 in the middle stage.
y, and a discharge passage 9z is formed in the lower stage. The ball passages 9a, 9b have proximity switches 10, 10 for detecting a pachinko ball on their side surfaces. On the other hand, the discharge passage 9z at the lower end
Is such that one pachinko ball can pass therethrough, and one pass switch 11 is attached to the lower end.

In the ball cutting passage 9y, the ball control rotary member 1 is provided.
Two are provided. The sphere control rotating body 12 includes three engaging claws 12b at 120 degree intervals on the outer circumference of the round bar-shaped body 12a,
A first ball control valve A and a second ball control valve B, which are formed by protruding 12b and 12b, are arranged in parallel. In the first and second ball control valves A and B, the engagement claws 12b of the first and second ball control valves A are displaced from each other by 60 degrees, and when the engagement claws 12b of the first ball control valve A are in the Y-shape, The engaging claw 12b of the second ball control valve B is in the reverse Y-shape. Then, every time the drive shaft 13a of the stepping motor 13, which will be described later, rotates by 60 degrees, the Y-shaped state and the inverted Y-shaped state alternate with each other. The engaging claws 12b, 12b ...
The shape of is a concave arc shape in which the push-out side of a pachinko ball fits the spherical surface, and is a semi-crescent shape in which the opposite back side is a convex arc shape. A tapered portion 14 that is inclined toward the point is formed. Both ball control valves A and B are arranged directly below the centers of the ball passages 9a and 9b, respectively. The body 12a of the sphere control rotating body 12 has the drive shaft 1 of the stepping motor 13 installed on the plate 8R.
It is fixed to 3a, and the sphere control rotator 12 is rotated clockwise in FIG. 3 by driving the stepping motor 13. The stepping motor 13 is a plate 8L,
The position of the engaging claw 12b is detected by the transmissive photodetector 15 provided between the 8Rs to control the rotation.

The ball releasing device 4A is constructed as described above, and the pachinko ball at the head of the ball passage 9a is the ball control valve A.
Between the two engaging claws 12b, 12b, and the ball passage 9b.
The pachinko ball at the head of the above is resting on the upper surface of the tip of the engaging claw 12b. Stepping motor 1 in this state
When the drive shaft 13a of No. 3 is rotated clockwise by 60 degrees in FIG. 3, the pachinko ball on the ball control valve A side has two engaging claws 1.
2b, 12b, is fed, is guided by the tapered portion 14 on the back of the engaging claw 12b, takes a course toward the midpoint between the ball control valves A, B, and is separated from the ball passage 9a to the discharge passage 9z. It falls and is detected by the passage switch 11. At this time, the next pachinko ball in the ball passage 9a is received by the upper surface of the tip of the back of the engaging claw 12b and stops.

On the other hand, the second ball control valve B includes the drive shaft 1
By the rotation of 3a, the engaging claws 12b, 12b, 12b become a Y-shape, and the pachinko ball supported by the upper surface of the tip of the engaging claw 12b enters between the engaging claws 12b, 12b and stops. Therefore, when the drive shaft 13a further rotates 60 degrees, the pachinko ball on the ball passage 9b side is discharged. In this way, each time the drive shaft 13a rotates by 60 degrees, one pachinko ball is alternately emitted from both ball passages 9a and 9b.
The drive shaft 13a (60 × emission ball) is received by receiving a normal winning signal for 15 pieces, a winning signal for 7 pieces, or a 25 piece ball lending signal from the ball lending device 16 as shown in FIG. number)
Just rotate it once.

Next, another sphere discharging device 4B suitable for carrying out the present invention will be described with reference to FIGS. In addition,
4 is a back view of the pachinko machine, FIG. 5 is a perspective view of the ball discharging device, FIG. 6 is a vertical front view of the ball discharging device, and FIG. 7 is Z- of FIG.
A sectional view taken along line Z and FIG. 8 are exploded perspective views of the piezoelectric linear motor. The sphere emitting device 4B uses a piezoelectric linear motor 17 as a drive source. The piezoelectric linear motor 17, as shown in the exploded perspective view of FIG.
8, an oval vibration transmission member 19 installed on the upper surface of the piezoelectric vibrator 18, a pair of sliders 20 and 20 slidable in contact with a linear portion of the vibration transmission member 19, A pressing guide plate 22 for pressing the sliders 20, 20 against the vibration transmitting member 19 by the elasticity of the spring 21, and the pressing guide plate 22.
Is a well-known one that is slidably supported toward the sliders 20 and 20 and is composed of a case body 23 that covers the piezoelectric vibrator 18 and the sliders 20 and 20 (for example, Japanese Patent Laid-Open Publication No. Sho. 61-35177, etc.). Piezoelectric linear motor 17
Is a device for transmitting ultrasonic waves from the piezoelectric vibrator 18 to the vibration transmitting member 19 and moving the sliders 20, 20 by a surface acoustic wave (Rayleigh wave) on the surface of the vibration transmitting member 19.
The two sliders 20 and 20 slide in opposite directions on the linear portion of the oval. Further, the sliding direction of the sliders 20, 20 is reversed by shifting the phase of the AC signal applied to the piezoelectric vibrator 18. Therefore, if the phase of the AC signal applied to the piezoelectric vibrator is shifted in a constant cycle, the two sliders 20, 20 reciprocate linearly in opposite directions of the linear portions of the ellipse. Ball control valves C and D in which the sliders 20 and 20 are provided with an inflow control valve 24 in the upper part and an exhaust control valve 25 in the lower part.
Are fixed via the connecting arm 26.

The ball discharging device 4B has a ball passage 9 on the right side in FIG.
B is bent in a substantially "U" shape, and the ball passage 9a on the left side is bent.
Is bent symmetrically with respect to the right-hand sphere passage 9b with respect to the vertical center line, and the confluence of the left and right sphere passages 9a, 9b is defined as one discharge passage 9z, and the passage switch 11 is provided in the discharge passage 9z. It is provided. The ball control valves C and D are provided at the ends of the ball passages 9a and 9b so as to be slidable up and down, and receive a pachinko ball on the discharge control valve 25 at a raised position to hold it in the standby chamber 27. , Inflow control valve 2 in the lowered position
4 blocks the ball passages 9a and 9b. Standby chamber 27 and discharge passage 9
z communicates with the ball control valves C and D in the lowered position.

Next, the discharging operation of the ball discharging device 4B will be described. First, when the ball control valve D on the right side is in the raised position and the ball control valve C on the left side is in the lowered position as shown in FIG. 6, the leading pachinko ball in the ball passage 9b on the right side is in the standby chamber 27.
The pachinko ball at the head of the ball passage 9a on the left side is blocked by the inflow control valve 24 and stopped before the standby chamber 27. When an AC signal is applied to the piezoelectric linear motor 17 in this state, the two sliders 20, 20 move in opposite directions, and the ball control valve D on the right side moves down and the ball control valve C on the left side moves up. By the operation of the ball control valves C and D,
The pachinko ball in the waiting room 27 on the right side is the discharge control valve 2
5, it descends, passes through between the standby chamber 27 and the discharge control valve 25, and is discharged to the discharge passage 9z. At this time, the pachinko ball in the ball passage 9b on the right side is prevented from flowing into the standby chamber 27 by the inflow control valve 24. On the other hand, when the ball control valve C on the left side in the lowered position is raised, the inflow control valve 24
Rises to open the flow path to the standby chamber 27, so that the leading pachinko ball enters the standby chamber 27 and stops.

As described above, when the sliders 20, 20 of the piezoelectric linear motor 17 operate once and the upper and lower positions of the left and right ball control valves C, D are switched, one pachinko ball is released. As described above, the piezoelectric linear motor 17 includes the piezoelectric vibrator 18
By shifting the phase of the AC signal applied to the sliders in a constant cycle, the sliders 20 and 20 and the ball control valves C and D integrated therewith can be linearly reciprocated, so that the number of released pachinko balls reaches the required number. It is sufficient to operate the piezoelectric linear motor 17 until it reaches. As in this embodiment, if the ball passages 9a and 9b are arranged in parallel on a plane parallel to the game board E surface and the piezoelectric linear motor 17 is used as a drive source, the ball discharging device 4B becomes extremely thin. It is effective for achieving the object of the present invention.

The embodiment of the present invention has been described above.
Of course, the present invention is not limited to the above embodiment. For example, the arrangement of the ball passages 3a and 3b of the outlet gutter 3 may be changed in the middle of the tank gutter 3T. Further, the ball discharging device may use, for example, a solenoid as a drive source in addition to the stepping motor 13 and the piezoelectric linear motor 17.

[0017]

As described above, in the pachinko ball discharge passage structure of the present invention, a plurality of rows of ball passages from the middle of the discharge gutter to the discharge gutter are arranged in parallel on the plane parallel to the back surface of the game board. Therefore, the ball passage hardly projects to the outside of the wooden frame at that portion, and therefore the protrusion on the back surface of the pachinko machine is reduced. As a result, the risk of damage during loading and unloading during transportation is reduced, and the number of obtrusive protrusions is reduced to improve the efficiency of the assembly work of the pachinko machine.
