ABSTRACT:
A paper whose width is to be detected is placed on a base. Two limiting members that can move towards or away from each other are situated on the two sides of the paper. The limiting members are moved to make a physical contact with the side of the paper. In this state, a rotation angle detection sensor detects an angle based on positions of the limiting members and outputs a signal based on the angle and an auxiliary sensor judges presence or absence of the limiting members in a certain range and outputs a signal. A width detection sensor detects the width of the paper based on the signals output from the rotation angle detection sensor and the auxiliary sensor.
