PURPOSE:To enhance resolution and to widen the detecting surface, by arranging a flexible sheet on one surface of a transparent plate, arranging a photoelectric- conversion-element group evenly on the other surface at a high density, and making it possible to input light from the side surface of the transparent plate. CONSTITUTION:A flexible sheet 4 is arranged on one surface 3 of a transparent plate 2 of a contact and pressure sensor 1. A group of photoelectric conversion elements 7 is arranged on another surface 6 evenly at a high density with a contactless distance being provided. An optical guide 11, which is connected to a light source (not shown) is arranged on one side surface 8 of the transparent plate 2 in one line. A plane mirror 13 is attached to another side surface 12. Of the elements 7 in, e.g., 16 rows and 30 columns, every 1 column is connected to a multiplexer 14, and 30 multiplexers 14 are connected to a computer 16 through different A/D converters 15. The sheet 4 is elastically deformed by a force F from the outer surface, and the outputs of the elements 7 are changed. The pressure on the sheet 4 and the distribution of the magnitude can be detected. |
