Claims

[Scope of utility model registration request]

(1) In an elevator equipped with a shaft-fixed support type governor that detects the running speed of a car, the governor rope of the governor is wrapped around the side or outer periphery of the governor wheel that rotates in conjunction with the car. It is characterized in that detected parts are provided on the surface at a predetermined pitch in the circumferential direction, and a sensor that detects the detected parts in a non-contact manner and generates a pulse signal is provided on the governor fixed part side. Elevator position detection device.

(2) A utility model characterized in that the detected part is a convex tooth formed on the governor wheel, and the sensor for detecting the convex tooth is a magnetic type, high frequency oscillation type sensor, or optical type sensor. An elevator position detection device according to claim 1.

(3) The detected portion is a striped reflective surface with different reflectance, and the sensor is a reflective optical sensor disposed opposite to the reflective surface.Claim 1 of the Utility Model Registration Claim: The elevator position detection device described.

(4) Any one of claims 1 to 3 of the claims for utility model registration, characterized in that two sensors are provided with a quarter pitch phase shift relative to the pitch of the detected part. The elevator position detection device described in .
