Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gate ball passage confirmation device that emits a rotating flash of light when passing through a gate of a gate ball.

[0002]

[Prior art]

 Since the conventional device for confirming the passage of a gate ball by a rotating flash is a device in which an electric light is fixed to the upper end of the gate via a casing, it is bulky and inconvenient to carry, and there is a problem that it is practically difficult to use. A rolling flash was emitted before the trailing edge of the ball left the trailing ends of both legs of the gate. In addition, there is a rule that the ball that dives under the gate at the first hitting gate must be separated from the gate by 10 cm before it can be recognized as passing the ball, and it is difficult to ensure accuracy by relying on the referee's visual inspection. (Actual No. 62-189770, Tokukai No. 60-7875). In other words, it was necessary to turn on the light after the ball had completely passed the gate or immediately after having passed the specified passing distance (10 cm).
