PURPOSE:To prevent deterioration in a printing quality and breakage of a film-form member, by providing a coating layer on either or both of ends of the film-form member and moreover providing a means detecting either or both of the ends of the film-form member. CONSTITUTION:In non-printing, film drive rolls 5, 6 are rotated by a drive mechanism, whereby a film 1 is traveled until coming into contact with a thermal head 7 at a film face of a coating layer 2 formed thereon and then brought to a stop. The coating layer 2 can be easily detected by detecting and end detecting hole 4 with use of a detecting mechanism of an end detecting hole 4 with use of a detecting mechanism of a photosensor etc. Thus, the coating layer disposed on either or both of ends of the film-form member is always is contact with the thermal head when a recorder is in a short non-printing period or left to stand for a long time, whereby the incompativility of the coating layer 2 with an ink eliminates the possibility that the ink becomes dry and sticks to the thermal head even if the recorder is left to stand for a long time. Therefore, sticking of the film to the thermal head due to drying or residue of the ink can be prevented from occurring to avoid deterioration of a printing quality and breakage of the film. |
