Claims

[Scope of utility model registration request]

(1) A case having a ball passage hole and a detection unit storage chamber,
A ball detection lever is attached to the case so as to be rotatable about an axis substantially perpendicular to the ball passage hole, and the tip portion of the lever projects into the ball passage hole; and a ball detection lever is provided integrally with the ball detection lever. A lever to be detected whose tip portion protrudes further inside the storage chamber; a spring that always rotates the lever to be detected and the ball detection lever in one direction and returns them to their original positions; A photoelectric detector consisting of a pair of light-emitting element and light-receiving element arranged in the storage chamber and the output signal of the case photoelectric detector are shaped into a pulse signal of -g width so that the amount of transmitted light changes suddenly due to rotational displacement. A pachinko ball detection device comprising a waveform shaping circuit.

(2) The photoelectric detector is a reflection type photoelectric detector that receives light from a light emitting element and reflected by the lever to be detected by a light receiving element, and detects the displacement of the lever to be detected from a change in the received light level. The inner surface of the storage chamber emits light from the light emitting element. The pachinko ball detection device according to claim 1, which is a registered utility model, characterized in that a concave portion is formed to prevent reflected light from entering the light receiving element.
