Abstract
Apparatus and method for use with a tape cartridge of a printer to determine halt of tape feed from a supply reel to a take-up reel of the cartridge comprising reflective and non-reflective portions on the supply reel rotating therewith and an assembly including a light source and a sensor fixed in position to face the supply reel to cooperate with the reflective and non-reflective portions without mechanical contact therewith for producing a train of successive electrical output pulses as the supply reel rotates. Upon cessation of the output pulses the tape feed is halted. The system also provides a mechanical locking device for effecting positive locking of the supply reel at the end of tape feed.
