するパチンコ球検出器。[Claim for Utility Model Registration] An annular ball passage having a through hole through which only one pachinko ball can pass, a case part provided on one side of the annular ball passage and housing a circuit board, etc.; It consists of a light emitting element that constantly emits light into a through hole, and a light receiving element that receives light from the light emitting element, and the pachinko ball that passes through the through hole of the annular ball passage blocks the light that enters the light receiving element and receives the light. In a pachinko ball detector in which the element generates a detection signal, a light emitting element is installed in the case part, and a light emitting element is installed at a position on the inner peripheral surface of the through hole of the annular ball passageway at a position where the light from the light emitting element can be received. Face the end of the fiber,
The optical fiber is guided into the case part by detouring the inside of the annular wall of the annular spherical passage, and further, the light receiving element is installed inside the case part and facing the end surface of the optical fiber located inside the case part. Pachinko ball detector.
