Ink-ribbon transfer device capable of fixing rotary roller

Abstract

The present invention is one ink ribbon conveyer with one fixed rotation shaft, and the ink ribbon conveyer includes one ink ribbon cassette, two rotation shafts and two fixtures. These two fixtures are mounted on two sides of one rotation shaft and penetrated through the rotation shaft and the ink ribbon cassette so as to fix the rotation shaft and the ink ribbon cassette relatively. Owing to the fixtures, the ink ribbon conveyer of the present invention can avoid the rotation of the shaft caused by external forces during transportation and prevent the loosening of the ink ribbon wound onto the shaft and the exposure of the ink ribbon cassette.

Description

Technical field

[0001] The invention relates to a ribbon transmission device, in particular to a ribbon transmission device capable of fixing a rotating shaft. Background technique

[0002] For the existing ribbon transfer device, because the rotating shaft used to drive the transfer ribbon is not properly fixed during the transportation process, the rotating shaft is easily affected by external forces, such as vibration during transportation or other unpredictable The vibration, while rotating relative to the ribbon cartridge. In this way, the rotating shaft can easily drive the ribbon wound on it, so that part of the ribbon can be unfolded, and even the ribbon can be loosened and exposed to the outside of the ribbon cassette. In addition, the existing ribbon transmission device is also prone to skew the ribbon due to similar reasons, even if the position of the ribbon on the rotating shaft deviates from the preset position. When printing the ribbon, the rotating shaft will driv...
