PURPOSE:To arrange so that a recorded image trace may automatically disappear by providing a heating means to heat a used ink donor film in a location on a winding means side instead of on a thermal head in a transfer-type thermosensitive unit. CONSTITUTION:A used ink donor film 2 passing through a thermal head 4 is wound around a film takeup roll 5 which shaft 5a is hollow and contains a bar heater 11. Consequently, the used ink donor film 2 wound around the takeup roll 5 is heated by the heater 11 and a solid ink is melted totally with a recorded image trace out of sight. Thus it is impossible to read a recorded image from the ink donor film 2. |
