PURPOSE:To enable the display of the current day mark on a calendar even in a narrow area by forming color in a thermosensitive paper depending on a partial current of transparent heat generating heads. CONSTITUTION:Transparent heat generating head (c) are formed on transparent ceramic plates (a) and (b) at the thickness of about 0.1mu by evaporation. A calendar made of a thermosensitive paper is put tight beneath the transparent ceramic plates (a) and (b) thus obtained. When specific one is selected from among the transparent heat generating heads (c) is selected to generate heat, the current day mark is displayed at the specified position of the calendar made of a thermosensitive paper. |
