Abstract

A ribbon support device for rotatably supporting a rolled ink ribbon includes a partitioning disk mounted in a terminal part of a ribbon core on which the ink ribbon is wound, the partitioning disk having a plurality of slits formed therein, and a reflection-type photoelectric sensor for detecting the slits, the sensor being located at a position facing the slits. Each rotation of the ribbon core is detected when the reflection-type photoelectric sensor has detected all the slits formed in the partitioning disk. The length of the ink ribbon supplied by one rotation of the ink ribbon is calculated by counting the amount of feed of a ribbon feeding stepping motor per rotation of the ribbon core.
