Area Monitoring Sensor
First Claim
1. An area monitoring sensor that emits detection light in different emitting directions and senses an intruder within a monitor area based on reflection of the detection light, the predetermined monitor area as a polygonal shaped area defined by three or more sides, the sensor being provided on a first side out of the sides of the monitor area, the sensor comprising:
- a side selecting unit that selects a second side other than the first side out of the three or more sides that define the monitor area based on an operation input;
a distance specifying unit that specifies a distance between the area monitoring sensor and the second side selected by the side selecting unit based on an operation input; and
an area size determining unit that determines a size of the monitor area based on the distance that has been specified by the distance specifying unit.

Abstract
This invention provides an area monitoring sensor capable of setting a monitor area without connecting a terminal device for area setting. The area monitoring sensor that emits detection light in different emitting directions and senses an intruder within a monitor area based on reflection of the detection light, the monitor area being previously set as a polygonal shaped area defined by three or more sides, the sensor being provided on a first side out of the sides of the monitor area, and includes a side selecting unit that selects a second side other than the first side out of the three or more sides that define the monitor area based on an operation input; a distance specifying unit that specifies a distance between the area monitoring sensor and the second side that is being selected by the side selecting unit based on an operation input.
