A mover is moved on the basis of information on lens and letter width. If letters picked up are mistaken, a fixation releasing command 130 is input, a releasing signal 136 is output, and a return feed signal 139 is output through ''and'' circuit 114. When letters are rightly taken up, a feed completion signal 132 is inputted, and a printing command 131 is inputted, light exposure is made by a printing signal 137, and the fixation of letter board is released by the print completion signal 134. Printing can thus be made by two switching operations for letter board fixation and printing and the efficiency of printing operation can be raised.
