Light and shade detected by a detector S are transduced into the sound and the pitch of the sound is heard from a speaker SP. The position of the detector S is set in the main body E with respect to the ruled line K in advance so that the printing is performed at the desired position. The main body E is moved to the desired position with the pitch of the sound from the speaker SP being heard, and the printing is performed. |
