Claims

[Claims for Utility Model Registration] 1. A drive shaft to which the rotational driving force of the motor is transmitted via a reduction mechanism, a pulley that rotates together with the drive shaft, and a transmission belt that is stretched across and stretched between the pulley and the drive shaft. a driven pulley;
a detected piece that moves in the belt tensioning direction in response to the rotation of the transmission belt, and a position of the detected piece that is disposed on the movement path of the detected piece and that corresponds to the amount of rotation of the drive shaft. A drive and shaft rotation amount detection device, characterized by comprising: a detector for detecting the rotation amount of a drive shaft; 2. The drive shaft rotation amount detection device according to claim 1, wherein the transmission belt is a wire whose one end and the other end are locked to a pulley. 3. The drive shaft rotation amount detecting device according to claim 1, wherein the detector is a photointerrupter having a number of combinations corresponding to the number of detected positions of the detected piece. 4. The drive shaft is a drive shaft for lifting and lowering the mounting plate on which objects are loaded.
