Abstract

A paper jam indication detection device detects an indication that a paper jam will occur in a paper feed device. The paper jam indication detection device includes: a sound collector that collects a friction sound produced by friction between a plurality of sheets of paper when the paper is fed from a holder holding the plurality of sheets of the paper; an indication detector that detects an indication that a paper jam will occur in the paper feed device based on a decrease in the friction sound collected by the sound collector; and a signal outputter that, when the indication is detected by the indication detector, outputs, to the paper feed device, a signal for stopping the paper from being fed from the holder.
