ABSTRACT:
A color dry silver (CDS) type color video printer using a color dry silver film on which a color printing is directly achieved, without using a copy sheet. The printer comprises a supply reel for supplying a CDS sheet, an exposure device for exposing the CDS sheet fed from the supply reel thereto to an optical image indicative of a picture to be printed, a capstan roller and a pinch roller for feeding the CDS sheet at a rate corresponding to an exposure rate of the exposure device, a cutting device for cutting the CDS sheet fed thereto at the trailing end of its portion exposed to the optical image, and a thermal development device for heating the cut CDS sheet so as to develop a latent image on the CDS sheet and discharging the CDS sheet through a discharging roller member. The printer also comprises a first sensor for detecting whether the CDS sheet is supplied from the supply reel, a second sensor for detecting whether the CDS sheet developed by the thermal development device is discharged, and a main controller for controlling the exposure according to detecting signals from the first and second sensors and controlling drive motors for the driving elements of the printer to regulate the overall system.
