Colored tape box

Abstract

The invention relates to a colored tape box used for a printer. The colored tape box comprises a shell body, a drive wheel, a driven wheel and a lever piece. Before the colored tape box is used for a first time, a clamping portion of the driven wheel and a clamping portion of the drive wheel do not make contact, and therefore the situation that the clamping portion of the drive wheel and the clamping portion of the driven wheel abut against at one point for a long time and deform or are damaged to be sticky can be avoided. When the colored tape box is used, after the drive wheel rotates, the driven wheel is driven by a gear part to rotate together with the drive wheel. Due to the fact that the lever piece which is fixedly arranged in the shell body is arranged between gear parts of the driven wheel in a penetrating mode, the driven wheel moves with the lever piece as a supporting point. After the driven wheel is separated from the lever piece, the driven wheel is continuously driven by the gear part of the drive wheel, so that the clamping portion of the drive wheel and the clamping portion of the driven wheel gradually abut against to clamp colored tapes. The colored tape box can remove the space distance between the clamping portion of the drive wheel and the clamping portion of the driven wheel without manual operation, improve use convenience, simplify the structure, reduce the number of assemblies, and greatly reduce cost.

Description

technical field [0001] The invention relates to a ribbon box for a printer. Background technique [0002] The printing method of the dot-matrix list machine is to use a plurality of needles on the list machine and can control the needles to hit a printing area, wherein the printing area is provided with a ribbon box, and the ribbon box is a ribbon with ink, so that the ink on the ribbon After the ink passes through the needle and hits the printing area, the ink can be printed on the paper, and after being continuously hit by the needle, characters or graphics can be formed on the paper. [0003] However, the ink ribbon cassette on this dot-matrix list machine needs to provide enough ink for printing, so a very long ribbon is used, and the foam layer or rubber layer on the two drive wheels is squeezed to clamp each other. Hold the ribbon, and use the two transmission wheels to rotate in opposite directions to drive the foam layer or rubber layer to move the ribbon, so that t...

Problems solved by technology

[0005] The above-mentioned color ribbon box that is free from foam deformation or rubber sticking, although there is an isolating device that can prevent the two foam wheels or rubber wheels in the color ribbon box from being squeezed against each other for a long time, the aforementioned isolation measures will make the color ribbon The structure of the cartridge tends to be complicated, and the manufacturing cost is relatively high, and consumers often forget to release the isolating device, so that the ribbon is used continuously in the same area, resulting in damage to the ribbon, resulting in a problem of failure after a short period of use. It is necessary to further review. and seek feasible solutions
