<p>PURPOSE:To execute input work while the object of input placed right under a main body and a transparent liquid crystal display are simultaneously viewed by providing the transparent liquid crystal display for the main body. CONSTITUTION:A worker places the object of input right under the main body 20 and he brings the on/off detection switch 11 of a write pen 10 into contact with a place to be inputted through a detection sheet 221 and the transparent liquid crystal display 21. A coordinate instruction detection part 22 detects the place where a capacitance changes and outputs an X-axis signal and a Y-axis signal, which show the place. A coordinate signal is inputted to a liquid crystal display control part 25 through a signal controller part 24 and is converted into a driving signal for the transparent liquid crystal display 21 in a liquid crystal driving part 26. Thus, the place which the worker brings the on/off detection switch 11 into contact with the detection sheet 221 is displayed on the transparent liquid crystal display 21. Thus, input work is easily executed even if the object of input is a complicated graphic or a solid shape object.</p> |
