置。[Claims for Utility Model Registration] It has a reflective sensor in which a light emitting element and a light receiving element are arranged side by side, and the light emitting element irradiates a passage through which an object to be detected passes, and the object to be detected passes through the passage. In a detection device using a reflective sensor, the light reflected by the object to be detected is incident on the light receiving element when the object is located at the light receiving element, and the presence or absence of the object to be detected is detected based on the output of the light receiving element. 1. A detection device using a reflective sensor, characterized in that the detection device includes an optical means for inputting light from the source through the passageway and guiding the incident light in a predetermined direction.
