Description of the Related Art Conventionally, setting and changing the number of prize balls in a pachinko machine have been described in, for example, Japanese Patent Application Laid-Open Nos. 54-54742 and 58-32786. This has been done by exchanging ball stoppers for setting the number of prize balls to be discharged in the ball case.

[0003] When a hit ball hit toward a game section of a game board surrounded by guide rails wins a winning opening, a predetermined number of prize balls are given to a player by operating a prize ball payout device. A pachinko machine that allows the number of prize balls to be paid out by a prize ball payout device by increasing or decreasing the number of prize balls to be paid out is disclosed in JP-B-61-44512.
Known as the official gazette.

However, the player operates a selection device provided on the front of the pachinko machine to reduce the number of prize balls to be paid out when it is easy to win a prize hole, and to use the prize when it is difficult to win the prize hole. Either one of the two with a larger number of balls to be paid out is selected, and the number of prize balls to be paid out by the prize ball payout device is made different from each other to two discontinuous values in accordance with the selection operation of the selection device. Was.

Japanese Patent Application Laid-Open No. 64-37980 discloses a plurality of parallel flow passages provided in parallel and a single merge passage for supplying prize balls flowing down the parallel flow passage to the counting means. A rectifying means for controlling the flow of the prize balls in the co-current passage is provided in the co-current passage so that all of the prize balls supplied from each co-current passage to the merging passage merge in the merging passage with a time difference. A prize ball flow passage mechanism of a pachinko machine is described.

The rectifying means in this device is constituted by a plurality of gears of the same size and shape sharing one rotating shaft, and the tips of the gears are arranged relatively shifted in the rotational direction by 30 degrees from each other. Have been. For this reason, when a prize ball falls from one of the parallel flow paths to the merge path, the prize sphere does not fall from the other parallel flow path to the merge path. The prize balls are alternately supplied to the merging passages from the two parallel passages with a time difference.

[0007] Japanese Patent Application Laid-Open No. 63-168193 discloses that
A counting gear is provided in each of the two ball passages, and the counting gears are arranged on one rotating shaft at an angle of 36 degrees with respect to each other in the rotating direction, and the rotating shaft is connected to the output shaft of the stepping motor via a gear train.

A dispensing machine of a pachinko machine which is detected as 0 is described.

In these two prior arts, the structure for alternately discharging (detecting) the spheres in each ball passage is as follows.
Since a plurality of gears provided for each ball passage and provided on one rotating shaft for ball feeding are arranged so as to be shifted from each other by a predetermined angle, adjustment of the mounting angle of each gear is troublesome. However, it is not easy to attach each gear to the rotating shaft. Therefore, it takes time to manufacture a sphere sending member composed of a rotating shaft and a plurality of gears rotating integrally therewith, and it cannot be easily manufactured.
