Abstract

PURPOSE:To attain a highly efficiency data reading with a simple constitution by light-receiving decoding and processing a reflecting light from a data file with a two-dimensional image sensor. CONSTITUTION:An optical card 6 is uniformly radiated by a light source 1, reflecting light due to this is converged by a lens 2, made incident on the CCD image pick-up element 3 of a two-dimensional image sensor and light-received. Reading data based on the intensity of the light in accordance with the presence or absence of the aluminum bit of recording data on a data storing area 7 are detected and converted to an electric signal. An output signal from an element 3 is processed by a seal-scanning in the horizontal direction of the element 3 and the successive charge transfer every one horizontal scanning with a data processing part 4, two-dimensional data are decoded as the coordinate data in the horizontal direction and vertical direction and displayed at a video displaying part 5. By the simple constitution of the combination of the optical system and the two-dimensional image sensor, the recording data can be read at high precision and at high efficiency in the stationary condition.
