摘要： PROBLEM TO BE SOLVED: To shorten a time necessary for the whole of erasing processing, while realizing the erasing processing which eliminates an unerased part of a thermal recording medium, even in the case of the thermal recording medium with a large surface area. SOLUTION: A record erasing device, which is provided a first heater substrate 5 and a pressure roller 7 for pressing the thermal recording medium against the first heater substrate, erases a visible image, which is recorded on the thermal recording medium, by applying heating treatment within a predetermined range of color erasing temperature to the thermal recording medium with a recording layer reversibly developing/erasing a color by heating. The record erasing device is provided with a second heater substrate 6 for heating the pressure roller, separately from the first heater substrate. Since this enables an increase in speed for increasing both the temperature of the first heater substrate and the temperature of the pressure roller, the time necessary for the whole of the erasing processing can be shortened.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for eliminating a written ink image, and an image erasing/recording apparatus with a built-in written ink image eliminating means, which prevent the scattering of an eliminated ink substance, and which enable the written ink image to be surely eliminated when peeling and elimination are intended, though a reversible recording medium is made writable and equipped with adhesion such that the written ink image cannot be easily peeled off, so as to be effectively usable as a substitute for paper. SOLUTION: This method for eliminating the written ink image on the surface of the reversible thermal recording medium is used for eliminating the ink image by making an elimination member linearly abut on the surface of the reversible thermal recording medium and relatively sliding them; and the ink image is formed, by using a writing instrument, on the surface of the reversible thermal recording medium whereon the image can be recorded, displayed and erased by virtue of a temperature change caused by heating. The surface of the reversible thermal recording medium has a dynamic receding contact angle of 75-100° with respect to distilled water. The degree of flexibility is 1.2 or more at least in an abutting part of the elimination member, which is composed of a nonwoven fabric including chemical fibers. COPYRIGHT: (C)2004,JPO
