Abstract
A recording and erasure of a visible image on a reversible heat-sensitive recording medium can be repeatedly performed in a stable condition without failure. The visible image is recorded by a thermal recording head on a display area of the recording medium. The recording medium has a non-display area other than the display area. The visible image is erased by providing heat from a thermal erasing head. The thermal erasing head contacts the non-display area before the thermal erasing head contacts the display area so that dirt adhering on the thermal erasing head is removed by friction between the thermal erasing head and the non-contact area of the recording medium.
