のためのエレベータ停止等のことが発生する。In the prior art, a rubber-based roller is generally used on the outer periphery of the roller of the position detecting device in order to improve noise or frictional force (prevention of slipping with an opposing pulley). , Fit or bake. As the elevator rotates together with the operation of the elevator, abrasion occurs, the diameter of the roller changes, and the number of output pulses for one rotation of the opposing pulley increases. When the number of pulses exceeds a certain value (when the roller diameter is reached), the roller is replaced with a new roller.

The hoisting sheave 4 is directly connected to the electric motor 5, and the car 1 moves up and down by the rotation of the electric motor 5. A lever 6 provided on a part of the car 1 is connected to an endless governor rope 7, which is wound around a governor pulley 8 of a governor provided in a machine room above the hoistway, and a lower folded part is a hoistway. It is wound around a tension pulley 9 installed at the bottom.

転する。On the governor pulley 8, a rope groove 10 for winding the governor rope 7 and a roller rolling surface 11 are formed concentrically.
Are disposed so as to come into contact with each other. The position detector 13 generates a number of pulses proportional to the amount of movement of the car 1, and uses this pulse count value as a position signal. The position signal from the position detector 13 is input to a control device (not shown) and used for speed control of the elevator, position signal, and the like. The position detector 13 includes an arm 15 and a torsion spring 1 on a frame 14 of the governor pulley 8.
6 and so on. Therefore, the roller 12 provided on the position detector 13 is pressed by a suitable pressure against the roller rolling surface 11 of the governor pulley 8 by the force of the torsion spring 16 and rotates synchronously with the governor pulley 8 without slippage.

, The roller 12 of the position detector 13 rotates,
As described above, the pulse signal is generated and the position of the cage 1 is output, but the roller 12 wears over time. For this reason, the number of rotations of the roller 12 with respect to the vertical distance of the car 1 increases, and the number of output pulses increases. However, as described with reference to FIG. 4, if the marks on the outer periphery and side surfaces of the roller 12 are periodically visually checked and the roller 12 is replaced, the control device will not hinder the operation of the elevator.
