。[Scope of Claim for Utility Model Registration] An optical medium detection sensor comprising one light projecting section that projects light onto the medium and a light receiving section that receives the light that is projected onto the medium and reflected or transmitted. a first light receiving section that receives light emitted from the light emitting section and reflected by the medium and converts it into an electrical signal; and a second light receiving section that receives the light emitted from the light emitting section and transmitted through the medium and converts it into an electrical signal. An optical medium detection sensor comprising: a light receiving section; and a determination circuit that inputs both the outputs sent from the first and second light receiving sections and determines the presence or absence or nature of a medium.
