Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge structure for a multicolor ribbon cartridge.

[Prior art] The conventional multicolor ribbon cartridge has a cartridge structure of 1
Two or more colors of ink were applied to the book ribbon cloth in the width direction of the cloth, and the ribbon cartridge was moved up and down to select colors and print in multiple colors.

[Problem to be Solved by the Invention 1 However, the above-mentioned conventional technology has the problem that when the ink of any one color band runs out, the ribbon cartridge itself must be replaced even if ink of another color remains. have The present invention is intended to solve these problems.The purpose of the present invention is to replace only the ribbon that has finished ink, so that ribbons of other color bands with remaining ink can be used as is, and the ink can be replaced. Our goal is to provide multicolor ribbon cartridges with high usage efficiency.

[Means for Solving the Problems] In the ribbon cartridge of the present invention, two or more endless ribbons coated with inks of different colors are arranged independently in the thickness direction of the ribbon cartridge.

[1] According to the above structure of the present invention, since the raw ribbon cloth of each color band is independent, when the ink is finished, the raw ribbon cloth of that color band or the cassette of the part to which the raw ribbon cloth belongs By replacing only the ink, ribbons of other colors with remaining ink can be used continuously, improving ink usage efficiency.

[Embodiment] FIG. 1 is a plan view of a ribbon cartridge according to an embodiment of the present invention with the cartridge cover removed, and FIG. 2 is a cross-sectional view taken along line AA' in FIG. 1. As shown in FIG. 1, in a ribbon cartridge that stores an endless ribbon in a cartridge case 1 and has a ribbon feed roller 3 and a ribbon driven roller 4 for winding up the endless ribbon 2, two ribbons are provided as shown in FIG. Endless ribbons are provided independently with the surface 5 of the cartridge case la as a boundary.

As a result, if the ink on either one of the endless ribbons 2a or 2b runs out first, the other ribbon can be replaced by replacing the finished ribbon cloth, or by replacing the entire cassette of the continuous ribbon cloth. Ribbons with remaining ink can now be used until the end.

[Effects of the Invention] As described above, according to the invention, by arranging ribbons of each color independently in a multicolor ribbon cartridge, it is possible to replace only the raw ribbon cloth that has been inked, and when other inks remain. This has the effect of making it possible to use the ribbon to the end and improving ink usage efficiency.
