摘要： Ribbon cassettes for typewriters or office machines of similar construction are subject to differnt structural requirements and primarily they are to be easily exchangeable in a one-hand operation. Since additionally the ribbon cassettes are also designed as disposable components, many still functional individual parts are also discarded. To avoid this, ribbon cassettes are known which have exchangeable ribbon spools. It is the object of the invention to provide a reloadable ribbon cassette in which the exchange of ribbon spools (4, 5) is possible with few manipulations. The removal of the spent ribbon spools (4, 5) should here be possible without soiling the fingers. This problem is solved in that the take-up spool (5) and the supply spool (4) are arranged to be freely placeable onto bearing pins (11, 12) in the bottom member (6) and the movable parts for guiding and transporting the ribbon (8) in the bottom member (6), which has a cup-shaped configuration, are mounted on one side and, except for the take-up spool (5) and the supply spool (4) which are freely placeable onto the bearing pins (11, 12), are arranged to be arrestable against falling out of the cassette housing if the cover (2) is open. This permits exchange of the ribbon spools (4, 5) with few manipulations without the operator performing this exchange soiling his/her fingers. The exchange of ribbon spools (4, 5) is also possible for less experienced operators not having special skills.

摘要： A ribbon cassette for an office machine, composed of: a cassette housing removably mountable in the machine, the housing having an entrance opening, an exit opening, an openable cover and elements constituting deflection points; a supply spool and a take-up spool having a core, each of the spools being removably mounted in the cassette housing; a carbon ribbon initially wound in the form of a coil on the supply spool, the ribbon having a leading end at the outer surface of the coil to be received by the take-up spool core to permit the ribbon to be wound up on the take-up spool while being unwound from the supply spool; and a fastening member secured to the leading end of the ribbon for threading the ribbon around the deflection points; and wherein the core is formed for enabling the fastening member to be fixed thereto to aid winding of the ribbon on the take-up spool.
