ABSTRACT:
An image read-out and recording apparatus comprises a device for splitting a light beam into a read-out beam and a recording beam, a common light deflector for deflecting the read-out beam and the recording beam, and a read-out sub-scanning device for moving an image original exposed to the deflected read-out beam with respect to the light deflector at an angle with respect to a direction of main scanning effected by deflection. A light detection system is provided for photoelectrically detecting light reflected by the image original, light passing through the image original, or light emitted by the image original when the image original is exposed to the read-out beam, and generating image signals representing an image recorded on the image original. The apparatus also comprises a modulator for modulating the recording beam with the image signals, and a recording sub-scanning device for moving a photosensitive material exposed to the deflected recording beam with respect to the light deflector at an angle with respect to the main scanning direction. A synchronizing signal representing a scanning position of the read-out beam on the image original with respect to the main scanning direction is provided by detecting an additional beam formed by splitting the deflected read-out beam.
