PROBLEM TO BE SOLVED: To obtain a large-capacity contact signal input device which enables more than several thousands of large-capacity contact input information to be inputted to one CCD image sensor at a time and which is made very small- sized and light-weight. SOLUTION: This large-capacity contact signal input discrimination device which takes in many contact input signals to perform a prescribed processing consists of an optical signal generation means 1 which converts the input signal of each contact to light, an optical fiber 2 whose one end faces to the light emission part of the optical signal generation means and the other end faces to plural pixels of a CCD sensor 4, and the CCD sensor 4 which generates a picture signal corresponding to input signals of respective contacts by plural pixels. The optical signal is introduced to plural pixels of the CCD sensor 4 through the optical fiber 2, and a corresponding contact input signal is discriminated by the picture signal generated by plural pixels. |
