Abstract
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.
