Abstract

PURPOSE: To secure discrimination of the position for the optical guide window via (M+N)-units of detectors by using the flat optical wave director to which the optical guide windows are arranged 2-dimensionally (M-row, N-columm) as an optical guide.
CONSTITUTION: The input device consists of flat optical director 3 used as an optical guide, light pen 4 which incorpotates the luminous element and contains a switch, optical guide window 5 to receive the light from pen 4, and code generator circuit 9 to deliver light emission start start signal 6 to indicate the light emission timing of pen 4, row address signal 7, column address signal 8 and code signal 10 respectively. At the same time, optical guide window 12 and 15 plus optical guide path 13 are provided to row optical director 11 and column optical director 14 which constitute director 3. In such constitution, one unit of the detector is enough to be provided to each row and column respectively, so the position of the optical guide window can be indentified via (M-row+N-column)-units of detectors.
