Title: Thermal transfer recording apparatus
Inventor: HISATAKE MASAYUKI
IPC: B41J2/32
Filed: 1984-09-20
Abstract: PURPOSE:To perform the entry of a character to the surface of recorded paper, by providing a coating means for forming a coating layer in response to a detected printing line. CONSTITUTION:A recording part 1 selectively heats the dot of a thermal head 2 on the basis of recording information SR to perform the thermal transfer of an image. The recording information SR is applied to a recording region detecting part 3 which in turn detects the region actually receiving recording on the surface of recording paper 10. A drive part 4 allows a pen 52, which applies a coating layer only to the recorded surface of the recording paper 10, to move to the direction at a right angle to the advance direction of the recording paper 10 on the basis of a signal. By this operation, the pen 52 applies the coating layer to perform the protection of the recorded part even if there is the recorded part even when only one printing dot is present in the line. By this method, coating layer applied parts and coating layer non-applied parts are present on the surface of the recording paper 10 in a line unit in a mixed state and the coating layer non-applied part can be written by the pen.
