Processing method for rewritable card and processing apparatus for the same

摘要

Disclosed is a processing apparatus for a rewritable card having a printing layer made of a heat-reversible recording material on which erasing/printing processes of images are repeatedly performed while traveling the card in a processing direction. The apparatus comprises an erasing/printing device for performing erasing/printing processes with respect to the printing layer; a heating device for performing heating process with respect to the printing layer; a temperature measuring device for measuring at least one of the temperature of the rewritable card and the ambient temperature in erasing/printing processes; and a control device for controlling the erasing/printing processes by the erasing/printing device and the heating process by the heating device according to the temperature measured by the temperature measuring device. The control device controls the erasing device to perform only one erasing process when the measured temperature is a reference temperature or more, and controls the heating device to perform the heating process prior to the erasing process when the measured temperature is lower than the reference temperature.
