<p>PURPOSE:To make the whole device compact, to reduce the production cost and to improve operability by forming a pattern input part of which input surface is constituted of a transparent body and a pattern output part having thermal head and superposing these parts. CONSTITUTION:A stylus 7 is moved on the input surface of a tablet 6. In the tablet 6, voltage pulses are alternately applied from a control circuit 6d to piezo- electric elements 6b, 6c and elastic waves propagated in the X and Y directions are alternately generated on an acrylic plate 6a. These elastic waves are detected by a leading voltage element of the stylus 7, the propagation time of the elastic waves is measured by a control circuit 6d and the positional information of the stylus 7 is sent to an XY recorder 11 through a signal processing part 3 as an XY coordinate signal. While following up the stylus 7, a thermal head 10 moves in accordance with the sent signal to execute heat sensitive recording on a heat sensitive sheet 9. The recorded pattern can be observed through the heat sensitive sheet 9, a sheet press 8 and the tablet 6.</p> |
