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.
