Claims

[Scope of utility model registration request]

a case body having a passage for pachinko balls;
It consists of an actuator that is biased in one direction and pivotably supported by the case body, with its pressure receiving part protruding into the passageway, and a detection circuit installed inside the case body. A light emitting element that emits light in an amount corresponding to a current supplied to the detection circuit from an external voltage source, a light receiving element that receives the light emitted by the light emitting element, and a light emission control element that controls the amount of light emitted by the light emitting element. , the light emission control element includes a voltage control element that controls the voltage of the current supplied from the light receiving element to a constant value, and the actuator is controlled by the pachinko ball passing through the passageway. 1. A sphere detection device for a pachinko game machine, characterized in that a light shielding portion blocks a light flux from the light emitting element to the light receiving element.
