ABSTRACT:
An image reading and recording apparatus has a first feed system for feeding an image-bearing sheet with image information recorded thereon to an image reading and recording device, and a second feed system for feeding a thermosensitive recording sheet to the image reading and recording device, the thermosensitive recording sheet having a support coated with a coloring agent, a color developer, and light-absorbing dyes, the thermosensitive recording sheet being capable of producing a color whose density depends on the thermal energy of a laser beam irradiated thereto. An optical laser beam scanning system scans the image-bearing sheet and the thermosensitive recording sheet with a laser beam in a main scanning direction while the image-bearing sheet and the thermosensitive recording sheet are fed in an auxiliary scanning direction in the image reading and recording means, to read the image information from the image-bearing sheet and record image information on the thermosensitive recording sheet. A photomultiplier converts the optical information read from the image-bearing sheet into an electric signal.
