Optical sensor.

摘要

There is provided an optical sensor having an optical block including a substrate (30), a light-emitting element (31) formed on the substrate, and a light-receiving element (33) formed on the substrate by using an adjusting member (32) for arranging side-by-side with the light-emitting element (31), a light-transmitting member (34) located between the optical block and an object, and control means optically connected to the light-emitting element (31) and the light-receiving element (33). It is preferable that the light-transmitting member (34) is separated into a plural in correspondence with areas separated on the object. There is also provided an optical sensor having a light-transmitting member, a plurality of incident optical fibers, optically coupled with the light-transmitting member, for transmitting light emitted from a light-emitting element to the light-transmitting member, a plurality of outgoing optical fiber, optically coupled with the light-transmitting member, for transmitting light passed the light-transmitting member after reflected on an object to the light-receiving element, and a housing for integrally housing the light-transmitting member, the incident optical fiber, and the outgoing optical fiber. <IMAGE>
