Abstract
A printer has a platen for holding a recording paper sheet, a thermal head which is arranged to oppose the platen and which is urged against and prints on the paper sheet in response to a recording signal, a pivot lever for urging or separating the thermal head against or from the platen, a drive source for moving one of the thermal head and the paper sheet relative to the other, so that a new recording surface of the paper sheet sequentially opposes a front surface of the thermal head, a slide clutch for feeding an ink ribbon guided between the paper sheet and the thermal head, and an intermediate rotary body driven by a straight rail member, both of which are interposed between and couple the slide clutch and the drive source, thereby actuating the slide clutch when the thermal head is urged against the platen.
