1. A paper jam indication detection device for detecting an indication that a paper jam will occur in a paper feed device, the paper jam indication detection device comprising:
a sound collector configured to collect 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 paper;
an indication detector configured to detect the indication that the paper jam will occur in the paper feed device by determining whether the friction sound has decreased by determining whether the friction sound is lower than a predetermined value set based on past history; and
a signal outputter configured to, when the indication that the paper jam will occur is detected by the indication detector, output a signal to the paper feed device for stopping the paper from being fed from the holder.
