Abstract

A paper feed device is mounted to a shredder. The intermittent activation time of paper feeding is adjusted, taking into consideration of the distance from the paper feed start position to the paper shredding position of a cutter of the shredder, thereby decreasing the speed of travel from the time the paper sensor detects the leading edge of the paper to the time the paper reaches the paper shredding position, so that operation is switched from intermittent to continuous activation preferably immediately before the leading edge of the paper reaches the cutter. Thus paper feed troubles associated with conventional devices are prevented, due to paper jamming, etc., caused by bending of the paper, etc.
