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.
