Abstract
A thermal transcription printer has a thermal head (8), a platen (9), a pair of pinch rollers (10), (11) disposed on both sides of the platen and a gearing apparatus consisting of gears (31), (32) and (33) and oneway clutches (29) and (30) and the gearing apparatus over-drives or reduces the rotation speed of the pinch rollers (10) and (11) and coupling of the oneway clutches and the gears is selected for making peripheral velocity of a pinch roller at a forward position against the paper conveyance faster than that at a backward position.
