ABSTRACT:
An object of the present invention is to provide a print medium identifying device that can accurately detect various print media. Thus, according to the present invention, a light emitting section (LED) irradiates a surface of a print medium P with ultraviolet light and different light of a longer wave. A light receiving section (regular-reflection photo sensor and diffusive-reflection photo sensor) receives the light reflected by the surface of the print medium P to output a signal corresponding to the quantity of light received. Identifying section (signal processing section) identifies the type of the print medium on the basis of a signal output by the light receiving section when the print medium is irradiated with the ultraviolet light and a signal output by the light receiving section when the print medium is irradiated with the different light.
