摘要： An optical position input device wherein an influence of disturbant light can be practically eliminated. The device includes a large number of light emitting elements and a large number of light receiving elements arranged in an opposing relationship along two sides and the other two sides, respectively, of directions of the X- and Y-axes. During driving scanning of the light emitting elements and the light receiving elements in the direction of the X-axis, a light reception signal developed in response to incident disturbant light from a selected one of the light receiving elements in the direction of the Y-axis is stored into a memory, and then the light reception signal is subsequently read out from the memory and is subtracted on a subtractor from a light reception signal developed from a light receiving element selected upon driving scanning for the direction of the Y-axis. The subtractor thus provides a position signal from which an influence of disturbant light has been eliminated assuredly. An influence of disturbant light is eliminated in a similar manner from a light reception signal developed from a light receiving element in the direction of the X-axis.
