Abstract

A pinch roller driving mechanism includes a second cam gear linked with a first cam gear which drives a loading block, and a pinch roller is driven by a pinch roller driving arm engaged with a grooved cam of the second cam gear. Owing to this construction, the timing of movement of the pinch roller can be deviated from that of the loading block, so that the path of movement of the pinch roller can be superposed on the path of movement of the loading blocks, what can make the construction smaller.
