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.

A roller type developing apparatus for a cycolor type color video printer. A pair of said plates are mounted on a base of the color video printer and spaced apart from each other, the side plates each is provided with a vertical mounting hole. The upper and lower pressing rollers each is rotatably supported between the side plates, and provided with a clearance for allowing the cylith film and the receiver paper to pass therethrough at the same time. The upper and lower support bearings are vertically mounted in each mounting hole of the side plate and connected to respective end shafts of the upper and lower pressing rollers, respectively, and each is adapted for supporting the upper and lower pressing rollers. The pressure controlling member is adapted for controlling the clearance in order to control the pressure for the upper and lower pressing rollers. The present invention provides a roller type developing apparatus which is provided with the clearance, thereby preventing the deflection of the pressing rollers and the jamming the cycolor paper, and providing the equality of the coloring and the compactness of the color video printer.

A cassette front loading apparatus for DAT of tray type which loads and unloads a cassette by moving horizontally and vertically is disclosed. Without utilizing separately the loading motor and the lift and drop motor for moving the cassette horizontally and lifting and dropping the same, with existing capstan motor only, the loading and unloading operation including the horizontal and vertical movement, slider opening movement, cassette take out movement and location detecting operation and the like are executed. Accordingly, the loading motor and the lift and drop motor and the number of parts are deleted, consequently all of the mechanism is very much simplified, therefore the preciseness and the durability are expected to be enhanced. Since all of the mechanism is simplified, the cost of the product is decreased and the assembling process became easier simultaneously the productivity is remarkably increased.

Cassette loading apparatus for digital audio tape recorder

A cassette front loading apparatus of a digital audio tape recorders for tray type which loads and unloads a cassette by moving horizontally and vertically. A single capstan motor is used for loading and for the lifting and dropping and for moving the cassette horizontally and lifting and dropping the same, to effect the loading and unloading operation including the horizontal and vertical movement, slider opening movement, cassette take out movement and location detecting operation and the like. Consequently all of the mechanism is very much simplified whereby the preciseness and the durability are enhanced.
