Claims

[Scope of Utility Model Registration Claim] A carriage that is moved back and forth on the knitting machine body to form a predetermined stitch; a tension applying device that applies tension to the knitting yarn, and photoelectric detection means that is installed in the knitting yarn supply path and that detects with light that a member that is displaced due to an increase or decrease in the tension of the knitting yarn is displaced from a reference position. A device for detecting yarn breakage, etc. in a knitting machine, characterized by:
