Abstract:
1. A structure for mounting a multi-optical axis photoelectric sensor having a front face and a back face, in which a columnar case for light projection or light reception that constitutes a multi-optical axis photoelectric sensor is mounted on a supporting wall with a back face of the columnar case facing a supporting wall side, to enable adjustment of an angle of light axis, the structure comprising: a rail-shaped projecting portion, formed on one side face or each side face of the columnar case along the longitudinal direction thereof, a movable-side member, having a gripping mechanism which detachably grips a rail-shaped projecting portion of the columnar case, a mounting portion, mountable on a supporting wall from the side facing the supporting wall, and a fixed-side member, rotatably supporting the movable-side member via a supporting mechanism, with the mounting portion mounted in a state where the columnar case is positioned on the side of the mounting portion, and further comprising a position fixing mechanism which fixes a positional relation between the movable-side member and the fixed-side member in an arbitrarily rotated position, whereby the fixed-side member positioned on the side of the columnar case makes the columnar case adjustable to an arbitrary optical axis angle via the movable-side member.
