PURPOSE:To establish the data input unit simple in construction and low in cost, consisting of the film sheet inserted between the rubber sheet and the printed board. CONSTITUTION:The flat plate rubber sheet 10 has the band shape conductor patterns 121 to 123 inserted in the band shape grooves in many number on the insulation rubber sheet 11, and the band conductor patterns 211 to 213 orthogonal to the said band shape conductive rubber patterns and the conductor patterns 221 to 223 for lead-out terminals of the said band conductive rubber patterns are printed on the printed board 20. The rubber sheet 10 and the printed board 20 are laminated through the insulation film sheet 30 having the notch hole 31 at the corresponding location to the crossing of the patterns. The input item sheet 40 is located corresponding to the notch hole 31 of the film sheet 30 on the upper surface of the rubber sheet 10. |
