Abstract

PURPOSE:To enable detection of parts with high reliability, without affected by reflection and scattering, by detecting the presence of parts in a transparent cylinder with a light emitting element and a photodetector incorporated in a light shield block adhered on an external wall of the transparent cylinder. CONSTITUTION:The presence of parts to be detected such as diodes which are kept in a cylinder 2 tentatively with a shutter 3, are detected through a photo detector and a light emitting element built in a light shield block 8 formed with two split blocks 9 and 9 adhered on an external wall of the transparent cylinder 2. The presence of parts are detected optically with high reliability through the constitution that scarcely affected by the reflection and scattering of light.
