<p>PURPOSE:To obtain a transparent digitizer which is inexpensive and whose quality is satisfactory, by placing a terminal in the periphery of a window of a frame type substrate having a window, and providing a coordinate line group between the corresponding terminals. CONSTITUTION:On a substrate 1, a rectangular window 2 is provided and conductor (round) groups 3-4, 5-6 are placed by one piece each in opposed positions, and conductive lines 7, 8 are extended. The lines 7, 8 are insulated covered wires and soldered to the round. It is also allowed that a post 18 is erected vertically in a position of the round groups 3-6 and soldered to the round, and an insulated wire is racked and provided. When a coordinate detecting circuit or a coordinate line selecting circuit of a part thereof is loaded on this substrate 1, a connecting process to the substrate is omitted thereby. The coordinate line group can be formed by only placing a metallic wire between terminals of the round or the post, therefore, it can be manufactured easily. Also, since a light transmission disturbance and a light reflecting part are small, a transparent digitizer whose light transmissivity is satisfactory is obtained.</p> |
