Abstract (en)
[origin: EP1500517A1] A ribbon support device for rotatably supporting a rolled ink ribbon (1) includes a partitioning disk (6) mounted in a terminal part of a ribbon core (4) on which the ink ribbon (1) is wound, the partitioning disk (6) having a plurality of slits (9) formed therein, and a reflection-type photoelectric sensor (10) for detecting the slits, the sensor (10) being located at a position facing the slits (9). Each rotation of the ribbon core (4) is detected when the reflection-type photoelectric sensor (10) has detected all the slits (9) formed in the partitioning disk (6). The length of the ink ribbon (1) supplied by one rotation of the ink ribbon is calculated by counting the amount of feed (or the number of steps) of a ribbon feeding stepping motor per rotation of the ribbon core (4). <IMAGE>
