Abstract
A ticket-printing device has a ribbon sensor and a mode-switching circuit. The mode-switching circuit automatically selects different printing conditions depending on whether or not the ribbon sensor detects the presence of an ink ribbon. The ink ribbon is wound on a supply spool and take-up spool. When the ink ribbon is replaced, a ribbon fixture holds the supply spool and take-up spool in correct relative positions so that they can be easily slipped onto a supply spool shaft and take-up spool shaft in the ticket-printing device.
