Abstract

A receptacle for a holder of a ribbon of a typewriter or similar machine. The holder has a base plate on which laterally pivotable retaining elements are disposed. The retaining elements support drive, braking and tensioning elements for the ribbon. If the retaining elements are pivoted away, a holder, e.g. in the shape of a ribbon cassette, can be inserted into the device. When the retaining elements have again been pivoted back, they surround the holder of the ribbon in the form of a shell. The drive, braking and tensioning elements then automatically take up their functionally correct positions. The device has the advantage that only the holder with the used-up ribboon need be discarded, while the drive, braking and tensioning elements remain in the device and thus can be repeatedly used. Manufacture of the holder with the ribbon is made considerably more economical this way and the value of the material to be discarded is reduced.
