Abstract

PURPOSE:To make a wrong action difficult to occur and to prevent output lowering by using an optical fiber as the information wire sending the light emitted from a luminous circuit part to an objective control circuit. CONSTITUTION:A sensor 1 is composed of a luminous part 1a and a light receiving part 1b, and the light 2 from the part 1a is made to be intercepted with a detected body placed between the parts 1a and 1b. On the other hand, a transistor Tr6 is a luminous control part, and when the light 2 becomes unincident to the part 1b, a voltage level becomes low, and an ON condition is given. Moreover, a luminous element 8 emits a light 9 only when the Tr6 becomes ON. The light 9 is led to an objective outside control circuit 11 with an information wire 10 composed of the optical fiber in which a photocoupler 10a is provided at the tip. As mentioned above, since an output medium is a light in this detection device, noise does not reverberate, and this causes a wrong action to be difficult to occur and moreover prevents the output lowering.
