PURPOSE:To omit a CPU, etc. to make the adjustment of an optical axis unnecessary and simplify the constitution by providing plural input/output parts consisting of pairs of reading parts and printing-out parts on the same substrate correspondingly to picture elements in the direction orthogonal to the moving direction. CONSTITUTION:An original 4 fed by a roll 3 is irradiated by a light source 5, and the reflected light is transmitted through an optical fiber 6 and is inputted to an optical sensor 8 of a head 7 for copying machine as one picture element and is converted to an electric signal and is amplified by an amplifying circuit 9. This signal is converted to heat by the resistance of an output-side printing- out part 10 and is printed on a thermal roll paper 12 as a variable density of a row of plural picture elements. Thus, only the circuit 9 is provided between the sensor 8 and the printing-out part 10 to make a RAM, a CPU, an optical system consisting of a polygonal mirror or the like, and devices for a photosensitive body, etc. unnecessary and the constitution is simplified thereby, and the optical axis adjustment, etc. of the device are made unnecessary to facilitate handling the device.
