た。2. Description of the Related Art In recent years, thermal transfer ink ribbons have been widely used in word processors and the like. However, when installing this thermal transfer ink ribbon in a ribbon cassette or replacing a new ribbon, the inelastic ribbon coated with thermal transfer ink on an extremely thin film is pushed out with a finger using a tension spring. The work of passing through the gap was troublesome, and also the work of soiling the fingers. In addition, since the tension spring is pushed and spread with fingers, the tension spring is often deformed or lost. Also,
As a countermeasure, there is one that locks the tension spring to the locking part.However, when attaching the lid, the ribbon may run without tension due to forgetting to release the lock, which may damage the printer. There were often too.
