1. An optical safety system comprising:
- a setting support device that generates an area designation information representing a protection area included in a detection area; and
a safety scanner, having a casing and a port configured to communicate an information with the setting support device, that detects an object within the protection area and outputs a sensing signal;
wherein the safety scanner includes;
an area designation information receiver that receives the area designation information from the setting support device;
a memory that stores the area designation information representing the protection area received from the setting support device as a registered area designation information representing a registered protection area;
a light emitter that emits a detection light to the detection area;
a light receiver that receives the detection light reflected from the object within the detection area and generates a light receiving signal in accordance with the detection light;
a distance calculation section configured to determine a distance to the object on the basis of the light receiving signal;
a scanner configured to direct the detection light to the detection area to scan the detection area in a circumferential direction around a rotation axis;
a distance measurement section that obtains a distance measurement information corresponding to the distance determined by the distance calculation section and a scanning angle of the detection light directed by the scanner; and
an intrusion sensing section that determines an existence of the object within the registered protection area on the basis of the registered area designation information and the distance measurement information obtained by the distance measurement section to output the sensing signal corresponding to the existence of the object within the registered protection area,wherein the setting support device includes;
an area designation information generation section that generates an area designation information representing a protection area as a new area designation information representing a new protection area;
a distance measurement information receiving section that repeatedly receives and updates the distance measurement information from the safety scanner;
a simulation generation section that generates a simulation of the intrusion sensing section in the safety scanner that represents an existence of the object into the new protection area on the basis of the new area designation information and the distance measurement information repeatedly received and updated from the safety scanner via the port;
an edit screen display section that displays the new protection area on an edit screen and a simulated information with respect to the existence of the object into the new protection area corresponding to the simulation of the intrusion sensing section in the safety scanner; and
a transmitter that transmits, to the safety scanner, the new area designation information representing the new protection area as the area designation information to be received by the area designation information receiver.

Abstract
Provided is an optical safety system that enables simplification of an editing operation for area designation information. A safety scanner includes an intrusion sensing section that determines the presence or absence of an intruder into a protection area. The setting support device includes a pseudo determination information generation section that determines a presence or absence of an intruder into a protection area on the basis of an area designation information before being transmitted to the safety scanner and a distance measurement information received from the safety scanner and generates a pseudo determination information indicating the determination result.
