A recording apparatus such as a thermal printer is compact in size and simple in construction, and has a recording head, a pulse motor commonly used for driving the head and for feeding a recording paper sheet, a cam with projections for transmitting the rotational force of the motor to the head so as to selectively move the head between the urged and separated positions with respect to the sheet or platen, ratchet gears to selectively couple the motor and a paper feed roller, and a projection and a guide roller to selectively hold the head at the separated position.
