2 is an operational state of a color video printer when using the sheet recording paper of the present invention.

3 is a working state of a color video printer when using the roll recording paper of the present invention.

The present invention relates to an apparatus for printing such that printing is possible using both a sheet recording paper and a roll recording paper in a color video printer.

In general, color video printers have been proposed in response to the need to print an image recorded by instantaneous deposition of an image signal or to print an image recorded on a monitor through a recording device such as a still camera, so that gray scale expression is free and all colors are available. A sublimation type thermal conductivity method is used in which three colors of yellow, magenta, and cyan can be sequentially sublimated.

That is, as shown in FIG. 1, the ink ribbon 101 to which three colors of Y, M, and C are sequentially applied is applied to the ink ribbon 101 and the recording paper 102 transferred from the surface of the platen drum 100. A thermally sensitive recording head 103 that is in close contact with each other, and a paper feeding unit 104 that conveys the recording paper 102 at a constant speed.

First, the printing process will be described. By rotating the platen drum 100, the recording paper 102 and the ink ribbon 101 proceed at the same speed with the platen drum 100 by the frictional force. At this time, the thermal recording head 103 generates heat and sublimates each dye of Y, M and C of the ink ribbon 101 by the amount of heat to be adsorbed onto the thermal sublimation recording paper, and The amount of synthetic color varies depending on the amount, which enables printing of all colors.

When the above operation is described in more detail, as shown in FIG. 1, the recording paper 102 into which the video printer in which the gap-stamp method is selected is introduced through a separate recording paper automatic feeding unit (not shown) is fed to the paper feeding unit 104. The recording paper 102 is drawn between the roller 104 'and the pinch roller 105 abutted against the rotational friction force of the paper feed roller 104' rotated clockwise by the power transmitted from an external power source. As a result, the recording paper 102 is positioned at the printing position via the platen drum 100 in which the recording paper 102 is rotated in the same direction.

Thereafter, the thermal recording head 103 moves downward to closely adhere the ink ribbon 101 to the recording paper 102, and then the feed rollers 104 'of the platen drum 100 and the paper feeding unit 104 are counterclockwise. The printing operation is performed while rotating, wherein the tip of the recording paper 102 is rotated at constant speed with the platen drum 100 and has a pressure greater than that of the thermal recording head 103 and the platen drum 100. The recording paper 102 is sandwiched between the paper feed roller 104 'and the pinch roller 105 to prevent slippage in the platen drum 100 to be printed. By the above operation, the first Y color is printed. Then, the thermal recording head 103 is lifted from the platen drum 100. At this time, the paper feed roller 104 rotates clockwise and the initial printing position. When the sheets are matched with each other, the recording sheet 102 is placed at the position for printing the M color. Thereafter, M color is printed by the same procedure as the above operation, and then, after printing the remaining C colors, the printed recording sheet is discharged toward the first paper loaded side.

However, such a device is a single-sheet recording when printing, but it has caused a problem that the machine can not be used widely, and the rear end of the recording paper to be printed during the printing process is placed in a free state between the thermal recording head and the platen drum. When entering, a case of entering into an uneven state occurs, which adversely affects the image.
