As a result, the ball stopper plate 29 is moved by the bias of the coil spring 35, and the notch 33 is engaged with the lower surface of the side edge of the through groove 28, so that the ball stopper plate 29 is reliably maintained at the ball stopper position. In order to release the ball stop, the ball stop plate 29 is pressed against the bias of the coil spring 35, is slid in the axial direction, and then is turned upward to reach the position. Reference numeral 36 denotes a seat screw for preventing the ball stopper plate 29 from coming off the support shaft 34, and reference numeral 37 denotes a stopper for preventing the ball stopper plate 29 from unnecessarily turning upward.

In the present invention, as shown in FIG. 6, an inclined step 38 is provided on the upper surface of the movable plate 14 so that the downstream sides of the spherical passages 9a and 9b are lowered. The downstream plate portion 14a on the downstream side of the step portion 38 is formed to have a size such that one pachinko ball rides thereon. Further, the upper side wall 91 of the ball passages 9a, 9b
c, a step 38 having substantially the same shape as facing the step 38
1 is provided.

Therefore, when the pachinko balls B are guided from the prize ball tank 4 to the prize ball dispensing device 7 and a plurality of pachinko balls B are continuous in the curve rail 6, the movable plate 1
4 is set so that the pachinko ball B1 just rides on the upper surface of the downstream plate portion 14a. In addition, the stepped portion 38 is arranged so that the pachinko ball B1 riding on the upper surface of the downstream plate portion 14a on the downstream side is positioned below a tangent line which is in contact with the upper portions of the pachinko balls B2 and B2 located on the upstream side and the downstream side. , Its height is chosen. As a result, the pachinko ball B1 on the upper surface of the downstream plate portion 14a receives a force that is sandwiched between the pachinko balls B2 and B2 on both sides and is pushed downward.

When the ball is removed by rotating the movable plate 14, the pachinko ball B1 that rides on the upper surface of the downstream plate portion 14a.
Is pinched from both sides by both pachinko balls B2 and B2, is pushed downward, and falls at the head. Further, the following pachinko balls B follow this and fall into the ball passage 13 in almost a single line. In this way, the pachinko balls do not fall into a dumpling shape near the entrance of the ball passage 13, thereby preventing the ball passage in the ball passage 13 from being clogged.

Also, both passages 9a, 9b of the curve rail 6 are provided.
As shown in FIGS. 3 and 5, a notch recess 39 is provided on the lower edge of the partition wall 6c which faces the downstream plate portion 14a of the movable plate 14, as shown in FIGS. The notch recess 39 is provided in the downstream plate portion 1.
The height from 4a is set slightly lower than the radius of the pachinko ball B. Therefore, there is no problem in pachinko ball B flowing down the curve rail 6. Therefore, when removing the ball,
As shown in the figure, both ball passages 9a, 9b of the curve rail 6
Although the pachinko balls B in the inside, that is, the pachinko balls B1 and B1 on the upper surface of the downstream plate portion 14a start to fall with the downward turning operation of the movable plate 14, both or one of the pachinko balls in the cutout recess 39 of the partition wall 6c. B1 partially enters, whereby the alignment state of the pachinko balls B1 and B2 in each of the ball passages 9a and 9b is broken, and these are disorganized and disturbed, and the ball passage 13
Therefore, it is not necessary to drop two pieces at the same time. Therefore, by providing the cut-out recess 39, the effect of preventing ball clogging in the ball ejection passage 13 is improved.

At the upper end of one side wall 92c of the vertical passage portions 92a and 92b, an outer surface 19d is formed as an inclined surface tapering toward the tip as shown in FIG. . Thus, when the movable plate 14 is rotated to remove the ball, the pachinko ball B riding on the upper surface of the downstream plate portion 14a
Even if the ball 1 is pushed by the ball pressure of the pachinko ball continuous to the upstream side and collides with the outer surface 19d of the one side wall 92c, the pachinko ball B1 slides downward along the inclined surface, so that the upstream ball It is pushed by the pressure and falls as it is.
Therefore, there is an effect that the ball can be reliably removed without causing the ball to bite.

Further, by providing the step portion 38, the direction of the pressing force applied to the pachinko ball B1 on the upper surface of the downstream plate portion 14a from the pachinko ball B2 on the upstream side and the direction of the pressing force applied to the pachinko ball B2 on the downstream side are defined. Deviates from the flow direction of the pachinko balls B on the entire curve rail 6, so that the ball pressure is slightly dispersed at this position, thereby reducing the ball pressure in the curve rail 6. Therefore, for example, in a prize ball dispensing apparatus in which a pachinko ball is cut and discharged one by one by a lead screw (not shown) rotated by a motor, no extra load is applied to the motor and the failure is small. It has an effect.

[0024]

As described above, the pachinko machine according to the present invention is provided with a stepped portion on the upper surface of the movable plate for slackening the ball, the height of which is lowered on the downstream side. Since the pachinko balls fall first and the following pachinko balls subsequently fall, the pachinko balls are almost in a line in the ball passage, and do not fall into a dumpling shape. Therefore, clogging of the ball in the ball passage is prevented.

Further, since the movable plate is provided with a stepped portion, it is economical and the production cost can be reduced since only the movable plate needs to be newly formed without making a major design change to the conventional curve rail.
