PURPOSE:To make a recorder compact and light in the device constitution in which letters, figures or the like written preliminarily on a rewritable photosensitive sheet are erased and then letters, figures or the like are written thereon again. CONSTITUTION:A first feed roller 6 for pressing a rewritable photosensitive recording sheet A to a heating resistor 1d is disposed on the surface side of a thermal head 1 and transferring the same, while a second feed roller 7 for pressing a rewritable photosensitive recording sheet A to a section close to the heating resistor and transferring the same is disposed on the rear face of the thermal head on the rear face side respectively. Then the printing voltage is applied to optional printing dots out of respective printing dots 1d' of the heat development resistor, and preheating voltage for heating respective printing dots 1d' to the temperature lower than the printing temperature of respective printing dots is applied. |
