Patent ID: 7084387

Claim:
A mounting structure for a multiple-optical-axis photoelectric switch including a light emitter having a plurality of light emitting elements aligned in a row and a light receiver having a plurality of light receiving elements corresponding to the light emitting elements and aligned in a row, at least one of the light emitter and the light receiver including a main case, the mounting structure adapted to fix the case to a predetermined mounting part so as to allow the case to pivot about a pivot axis extending along a direction of alignment of the elements, the mounting structure comprising: a first member attached to a longitudinal end of the main case and having a protrusion extending in the direction of alignment and having an arc cross section comprising a concave surface; and a convex surface; a second member; and a third member; and a mounting device, wherein the protrusion of the first member is interposed between the second member and the third member; wherein one of the second member and the third member has a concave surface to slidingly interface with the convex surface of the protrusion of the first member; and wherein the other of the second member and the third member has a convex surface to slidingly interface with the concave surface of the protrusion of the first member; and wherein one of the second member and third member is formed with at least one screw insertion hole extending therethrough; and wherein the other of the second member and the third member is formed with a fixing section adapted to be fixed to the mounting part and at least one screw hole adapted to be threadingly engaged with the mounting device; and wherein the protrusion of the first member can be fixed in position by tightening the mounting device; and wherein the mounting device is operated generally perpendicular to the pivot axis.
