ABSTRACT:
A reloadable ribbon cassette system for typewriters or office machines of similar construction employs a housing which receives an exchangeable supply spool for the ribbon and an exchangeable take-up spool core. To facilitate the reloading process, the take-up spool core is mounted in the housing on a bearing pin which extends upward from a contact surface. The take-up spool core has a bearing bore into which the bearing pin extends and a bearing surface which rests on the contact surface. The contact surface is disposed closely below a receiving bore in the take-up spool core which accommodates a fastening element attached to the end of the ribbon.
