Abstract

PURPOSE:To prevent an ink ribbon from being wasted, enhance printing quality and enable printing time to be shortened, by a construction wherein the rotating force of a rotary shaft in the lowermost cassette casing is transmitted sequentially to rotary shafts in upper cassette casings. CONSTITUTION:In the case of multicolor printing, the cassette casings 1 respectively incorporating ink ribbons 8 of desired colors are sequentially stacked. A ribbon-driving shaft 13 is engaged to a fastening recessed part 14 of the rotary shaft 9 in the lowermost cassette casing 1, and a fastening projected part 15 provided at the top end of the shaft 9 is engaged to a fastening recessed part 14 of the rotary shaft 9 in the casing 1 located directly above the lowermost casing 1, and so on. Therefore, the ribbon-driving shaft 13 and all of the rotary shafts 9 can be coaxially rotated as one body by a motor 19. Accordingly, by setting the ribbon 8 in the selected casing 1 to a printing position, it is possible to print in the desired color while preventing mixing of colors from occurring, whereby printing quality can be enhanced. In addition, it is possible to prevent the ribbons from being wasted, by replacing only the consumed ribbon 8 by a new one together with the casing 1. Further, printing time can be reduced, by fitting the casing 1 incorporating a monochroic ribbon 8 used most frequently and printing in the color in a single stroke of scanning.

TECHNICAL BACKGROUND OF THE INVENTION AND PROBLEMS THEREOF Conventionally, there are printers that print using a ribbon cassette in which ink ribbons color-coded into a plurality of zones are housed in a cassette case. However, since the frequency of use of each color is different, if ink of one color runs out, all ink must be discarded even if other colors can be used, which is extremely uneconomical.

Furthermore, the difference in the frequency of use of each color is manifested as a difference in the impregnation rate of the ink, and ink is absorbed toward the side with a lower impregnation rate, which causes smearing, bleeding, color mixing, etc., and deteriorates print quality. Furthermore, in the case of three-color ink ribbons of yellow, red, and blue, it is possible to print on the top package by overlapping the colors and printing. For example, if three colors of yellow, red, and blue are overlapped, black printing will be obtained, but in this case, the printing time will be twice as long. Therefore, it is extremely inefficient when printing mainly text.

Summary of the Invention This invention engages a ribbon drive shaft with a rotating shaft inside a cassette case to feed an ink ribbon, but if necessary, a plurality of cassette cases containing ink ribbons of different colors can be stacked and connected. so that the rotational force of the rotational shaft of the lowermost cassette case can be transmitted coaxially to the rotational shaft of the uppermost cassette case in sequence;
Any cassette case can be placed opposite the printing section to print in the desired color.This allows only the worn out ink ribbon to be replaced along with the cassette case, preventing color mixing and improving print quality. Furthermore, by installing a cassette case containing frequently used single-color ink ribbons, it is possible to print in the desired color in a single scan, reducing printing time. be.

Effects of the Invention Since the present invention is constructed as described above, when performing multicolor printing as required, simply stacking a plurality of cassette cases containing ink ribbons of a single color can rotate the rotation shafts of all cassette cases. The ribbon can be rotated multiple times by the ribbon drive shaft, and by aligning the ink ribbon in the selected cassette case with the printing position, printing can be performed in the desired color.Furthermore, color mixing can be prevented. In addition, only the worn out ink ribbon can be replaced along with the cassette case to prevent ink ribbon wastage, and a cassette case containing frequently used single color ink ribbons can be installed. By doing so, it is possible to print in a desired color in one scan, thereby reducing the printing time.
