Claims

[Scope of utility model registration request]

(1) Reflection in which a light-emitting part and a light-receiving part are placed facing each other at a distance from a transparent member having a surface in contact with the object to be detected, and the object to be detected in contact with the surface is optically detected by reflected light. A reflective type detection device, characterized in that a light control means is provided between the optical path of the light emitting section and the light receiving section.

(2) The reflective detection device according to claim 1, wherein the light control means is configured to prevent more than a predetermined amount of light directly reflected from the transparent member itself from entering the light receiving section.

(3) Reflective detection according to claim 1 or 2, wherein the light control means is made of a low-reflection material provided on the side of the transparent member that is not in contact with the object to be detected. Device.

(4) The reflective detection device according to claim 1 or 2, wherein the light control means is made of a low-reflection material provided near the light receiving section.
