Abstract
A paper carrying device includes a carrying path, a light sensor, a contact sensor, and a judgment section. Both of the light sensor and the contact sensor output a presence-signal indicating that paper exists at a predetermined position in the carrying path or an absence-signal indicating that paper does not exist at the predetermined position. The judgment section judges that a signal output from the light sensor is an error when the light sensor outputs the presence-signal while the contact sensor outputs the absence-signal.
