Abstract
A detecting apparatus for detecting an object passing through a space between a light emitting element and a light receiving element, comprises a first optical body forming a first mirror between a light emitting lens and a light receiving lens; and a second optical body forming a space passing the object therethrough by opposing to the first optical body, the second optical body having a second mirror. The light emitting element emits the light from the light emitting lens to the second mirror, while the light receiving element converts the light incident through the light receiving lens into electric signals. The light emitting and receiving elements are formed on a control circuit substrate. The aforesaid all components are incorporated compactly in a casing of the detecting apparatus.
