Patent

CA 2056850

There is provided an optical sensor having an optical block including a substrate, a light-emitting element formed on the substrate, and a light-receiving element formed on the substrate by using an adjusting member for arranging side-by-side with the light- emitting element, a light-transmitting member located between the optical block and an object, and control means optically connected to the light-emitting element and the light-receiving element. It is preferable that the light-transmitting member 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.
