PURPOSE:To simplify marking mechanism and operation by putting a mark on the surface of a thermosensitive sheet with the heat of a heating body. CONSTITUTION:A reading head 6 is arranged freely movably on a supporting surface 2 and is provided with a transparent plate 4 having a formed index. The extent of movement of this head 6 to the supporting surface 2 is counted by a controller which is not shown in Fig., and this counted value is outputted. In this case, the thermosensitive sheet 8 is plotted preliminarily to position the sheet on the supporting surface 2, and the heating body 10 is arranged in the position where the head is close to the sheet 8 on the supporting surface 2. Thus, the coordinate read position on the surface of the sheet 8 is marked by the heat of the heating body 10. |
