Abstract (en)
Provided is an elevator controller which can substantially simplify the labor for installation and adjustment and can detect car positions with high accuracy regardless of the skills of workers who perform installation and adjustment. This controller is provided with an encoder which detects the rotation of a sheave and first position detection means which detects a car position on the basis of detection results of the encoder. Furthermore, this controller is provided with an image indication part which is provided in an end portion of a shaft and an image detection part which is provided on the car. The image detection part detects an image indicated on the image indication part. Second position detection means detects a car position on the basis of detection results of the image detection part. An image writing part adjusts the position of an image indicated on the image indication part on the basis of the car positions detected by the first position detection means and second position detection means.
