Abstract

PURPOSE: To provide the subject detector equipped with a shaking piece shaking in the pressing direction of a warp yarn and axially supported near either one of both top and bottom dead points of a warp yarn group performing a shedding motion and further a projector and a light receiver on an optical path formed by the shaking piece and capable of suppressing the fluffing and yarn breakage of warp yarns and performing sure detection. CONSTITUTION: A shaking piece 6 shaking in the pressing direction of warp yarns 5 is axially supported in the vicinity of a position of at least either one of top and bottom dead points in positions for passing a warp yarn group 5 alternately performing vertical motion between the respective dents 4 by a shedding motion of a heald 1, and a projector 7 and a light receiver 8 are arranged on an optical path formed by the shaking piece 6 to compose a detecting means. Thereby, contact with the warp yarns 5 is extremely reduced. As a result, fluffing is suppressed to prevent yarn breakage from easily occurring. Since the detection is carried out near the top and bottom dead points of the warp yarns 5, the presence or absence of a loosened state of the warp yarns 5 can be detected.
