Abstract
A paper feeding unit includes: a detecting board formed of a regular-polygonal prism having a multiple number of sensors; a detection block with sides which each have a multiple number of signal generating portions and are able to face the sensors; a holder portion holding the detection block so as to allow the posture of the block to be changed to fix the block at setup positions; and a display window which allows a paper-size indicator displayed on the signal generating portions of the detection block to be seen from the outside. In this configuration, the orientation and position of the detection block are adapted to be changed in accordance with the size of paper held in the paper feed cassette.
