Abstract

PURPOSE: To detect the passage at a preset position of multiple running bodies automatically and separately in an non-contact manner in response to the output of a separate receiver by controlling a transmitter in response to the output of a light receiving element which has received the light beam projected transversely with respect to the courses of the running bodies.
