A head driving mechanism for driving a recording head for a recording apparatus, includes a cylindrical head slide shaft, a head carriage formed with a circular bore so as to be slidably and rotatably fitted, at the circular bore, around the head slide shaft. A prismatic cam shaft which is engageable with the head carriage is also provided for rotating the head carriage, and an elastic member and a solenoid are provided for urging the cam shaft in opposite directions. Upon energization of the solenoid, the cam shaft is rotated in a direction such that the recording head is selectively depressed against a platen by a driving force of the solenoid and upon de-energization of the solenoid the cam shaft is rotated by an urging force of the elastic member such that the recording head is disengaged from the platen.
