Title:
PHOTOELECTRONIC SENSOR
Document Type and Number:
Japanese Patent JP2018170158
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enlarge application examples of display by use of a light-emitting source for display as to a photoelectronic sensor which makes a tip of a light propagation member shine by causing the built-in display light-emitting source to light.SOLUTION: A photoelectronic sensor comprises: a floodlight-use connection part to which a floodlight-use light propagation member to be optically coupled to a light-emitting element is to be connected; a light receiving-use connection part to which a light receiving-use light propagation member to be optically coupled to a light-receiving element is to be connected; a signal generation part which compares a received light signal generated by the light-receiving element with a threshold to generate a detection signal showing a result of the comparison; an optical display light-emitting element which is optically coupled to at least one of the light receiving-use connection part and the floodlight-use connection part and emits visible light; and a control part which causes the optical display light-emitting element to light according to a light reception state of the light-receiving element based on the received light signal, and causes the optical display light-emitting element to light based on an instruction from outside.SELECTED DRAWING: Figure 1
