In the detection device for conveyed paper, the contactor is constituted by a hanging piece whose normal position, with its tip end facing the conveyance path, is formed by its own weight, and the contactor is subjected to a spring force in the normal position. What is claimed is: 1. A paper conveyance detection device characterized in that it is provided with a spring means that applies a spring force in the direction of a normal position at a predetermined swing angle or more without applying a spring force.
