置。[Claims for Utility Model Registration] A cassette identification device for identifying a plurality of types of cassettes into which paper of different sizes can be loaded, the cassette is provided in a part of the cassette and reflects light according to the size of the paper to be loaded. Alternatively, marker members having different transmittances, a light emitting/light receiving means that irradiates the marker member with light and receives the reflected light or transmitted light when the cassette is attached, and an output corresponding to the amount of light received by the light emitting/light receiving means. an analog/digital converter for converting a signal into digital data; a storage means for storing a plurality of digital data outputted from the analog/digital converter according to a plurality of types of cassettes; and a digital data stored in the storage means. A cassette identification device characterized by comprising a calculation means for calculating identification data corresponding to each cassette based on the data, and an identification means for comparing the identification data and digital data to identify the type of the cassette.
