Claims

[Claims for Utility Model Registration] (1) A cylindrical case that is open at one end and has a hollow portion; a rod-shaped contactor extending in the direction; and a pair of first light beams each attached to the case and cooperating with each other to define a first optical path extending in a direction perpendicular to the axis of the contactor in the hollow part. and a second optical path, each of which is attached to the case, cooperates with each other, extends in a direction perpendicular to the axis of the contact, and is located closer to the other end of the case than the first optical path. a pair of second detecting sections defining a distance in the hollow portion, one of the first detecting sections outputs a first signal when the contact passes through the first optical path; One of the second detection units is a contact position sensor that outputs a second signal when the contact passes through the first optical path. (2) One of the first detection section and one of the second detection section is composed of a light receiver, and the other of the first detection section and the other of the second detection section are composed of a light projector. 1. The contact device sensor according to 1. (3) One of the first detection units is composed of a light emitter/receiver that emits and receives light; one of the second detectors is composed of a light emitter and receiver that emits and receives light; The contact position sensor according to claim 1, wherein the other of the first detection section and the other of the second detection section are comprised of reflective plates. (4) Claim further comprising a coil spring having one end fixed to the contact and the other end fixed to the side of one end of the case, wherein the contact receives a spring force when it is moved. 1. The contact position sensor according to 1.
