A holder of a ribbon with supply and take-up spools for typewriters and similar machines where the holder is insertable into a receptacle of the machine and has guide elements for the ribbon. The retention elements for the ribbon are designed so that the ribbon slides out of them when the side elements of the receptacle are pivoted back into their operational position. This assures on the one hand, that the ribbon is secured in a position during movement in the course of shipment which easily makes possible the insertion of the holder into the receptacle. On the other hand it is also assured that the ribbon is pushed out of these guidance elements during insertion of the holder into the receptacle and in this way attains its functionally correct position in the typewriter.

Holder of a ribbon with supply and take-up spools for typewriters or

A holder of a ribbon for typewriters or similar machines in which the ribbon can be transferred from a supply spool to a take-up spool and where the two spools are disposed on a slider. By means of the invention it is intended to manufacture the slider for the two spools in as simple a manner as possible and without further assembly steps. This is made possible when the holder, together with the slider for the ribbon spools, is initially made as a one-piece plastic part. It may also have a pivotable cover so that a cassette is formed after insertion of the spools and closing of the cover. The one-piece construction of the holder with the slider also makes securing for transport unnecessary. When the holder is inserted into a correspondingly designed receptacle, the slider is separated from the holder by breaking off from thin connecting points at so-called predetermined breaking points and it is positioned a little higher than the holder on the respective guide bars of the receptacle. After laterally pivotable side elements of the receptacle have been moved in, the ribbon is in a functionally correct position in the typewriter or the printer. Because of this design of the holder in connection with the receptacle, simple manipulation in the course of the insertion of a new ribbon is achieved.

Holder of a ribbon for typewriters or similar machines

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.

Receptacle for a holder for a ribbon for use in typewriters or similar

A holder for a ribbon for typewriters or similar machines where the holder is insertable into a receptacle. The holder must assume a firm and above all functionally correct connection with the receptacle. For this purpose two sliders with hook-shaped ends are disposed on pivotable side elements of the receptacle. These hooks embrace in their locking position edges provided on the ribbon guide arms. Only when the hooks are in their closed position can the combined device be inserted into the typewriter or the printer. The operationally correct insertion of the combined device would be prevented by a side element which is not closed or a protruding slider with its hook.
