Abstract
A multi-feed detection device includes: an arm member supported swingably and configured to come into contact with a traveling sheet; and detecting means for detecting whether a plurality of the traveling sheets are overlapped and fed, on the basis of swing of the arm member. The detecting means includes: a detection plate attached to an arm; and a non-contact sensor configured to measure, in a non-contact manner, the positional relation between the non-contact sensor and the detection plate, the positional relation being changed by swing of the arm.
