Title: Multi-optical-axis photoelectric sensor
Inventor: FURUTA HIROMASA
IPC: G01V8/14
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a multi-optical-axis photoelectric sensor capable of detecting at a high S/N ratio and reducing cost by cutting down the number of elements. SOLUTION: In this multi-optical-axis photoelectric sensor, diffused light emitted from a light projecting element 11 is changed into light with a plurality of parallel optical axes while traveling one round between a sensor body 10 and a multiple-string prism 20, and received by each light receiving element 12. That is, the frequency of round trips of the light is less in comparison with a conventional one, and the light does not pass through a half mirror, so that the decay of light is little. The sufficient light receiving quantity to the light receiving element is thereby secured to permit detection at the high S/N ratio.  Furthermore, because of the constitution of providing one light projecting element 11 for a plurality of light receiving elements 12, the number of elements is cut down to attain cost reduction in comparison with the conventional constitution provided with the light projecting elements in the same number as the light receiving elements.
