Description

  The present invention relates to a mirror device having a mirror that reflects light from a multi-optical axis photoelectric sensor and an attachment structure in which a multi-optical axis photoelectric sensor is attached to an attachment location such as a machine frame or a wall via a fixing member.

  The conventional long object mounting structure shown in FIG. 8 is a structure in which a long object is attached to an attachment location 3 via a fixing member 4. On this long object, on both sides of the long attachment part 6 to which the fixing member 4 is applied, a flange part 7 extending in the longitudinal direction X of the long object in parallel with a gap from each other, and its flange A locking portion having a locking groove 8 extending along the flange portion 7 is provided inside the portion 7, and the fixing member 4 is engaged with both sides of the mounting portion 11 to which the long object is applied. Stop portions (the sandwiching portion 18 of the outer sandwiching plate 12 and the sandwiching portion 19 of the inner sandwiching claw 13) are provided at intervals. The both inner clamping claws 13 are supported by fixing screws 20 so as to be rotatable independently of each other on both sides of the outer clamping plate 12. With the attachment portion 11 of the fixing member 4 fitted between the both locking portions (the flange portion 7 and the locking groove 8) of the long attachment portion 6, both inner clamping claws 13 are separately separated from each other. When the holding member 12 is rotated, the fixing member 4 takes the locking position Q and the locking release position P. At this locking position Q, the clamping portions 19 of both inner clamping claws 13 are engaged with the locking grooves 8, and the flange portion 7 is clamped between the both clamping portions 18 and 19.
