<p><P>PROBLEM TO BE SOLVED: To provide an infrared sensor capable of easily and precisely setting a detection zone in which an intrusion object is not detected among a plurality of detection zones set in a detection area. <P>SOLUTION: An infrared sensor 1 comprises: a condenser lens 101 including a plurality of lenses in a first direction; a light receiving element 103 for receiving infrared ray; light shielding members 161 to 163 for shielding the infrared ray; and a shield guide 120 for supporting the light shielding members. One of the light shielding member and the shield guide displays plural pieces of identification information indicating each of the lenses. Two pieces of identification information adjacent to each other are displayed in the same positional relation with a mutual positional relation of the two lenses corresponding to the respective pieces of information. The other of the light shielding member and the shield guide comprises indication means for indicating a display of identification information showing a lens shielded by a tip part of the light shielding member or an unshielded lens adjacent to the lens. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
