Abstract

The present invention provides a winding device and a printing device. The winding device can reduce the number of gears for winding tapes. The winding device includes: a sun gear, which is engaged with a drive gear; a planetary gear which is engaged with the sun gear and moves around a rotational axis of the sun gear; and a winding gear, which includes a winding shaft for printing tapes in a central axis, is engaged with the planetary gear through the movement of the planetary gear to a first position, and thus is interlinked with the planetary gear and rotated.

Description

technical field [0001] The present invention relates to a tape winding device and a printing device. Background technique [0002] Recently, various printing devices for printing or printing characters, images, and the like on paper media are widespread. This printing device has, for example: a platen supporting a paper medium, and a printing head reciprocating along a predetermined moving direction. to print on. [0003] In addition, the printing device includes a tape winding mechanism for winding the ink ribbon. The tape take-up mechanism rotates a take-up shaft of the ink ribbon based on a rotational drive force transmitted from a drive gear fixed to a drive motor that drives the print head. Here, the drive motor rotates in the first direction and the second direction opposite to the first direction to reciprocate the print head. Therefore, the tape winding mechanism, as described in Patent Document 1 and Patent Document 2, is responsible for winding the ink ribbon e...
