Abstract
The present invention comprises an endless belt which is provided with perforations at the edge on the opposite sides at a regular interval, a pair of belt pulleys around which said endless belt is suspended, a sprocket wheel which is disposed substantially at midway between the pair of pulleys and whose teeth engage with the perforations on the endless belt, a stepping motor which drives the toothed wheel, and a drive circuit which drives said stepping motor. Said sprocket wheel has a diameter larger than that of the pulleys, so that the endless belt would tightly press against the sprocket and held in place.
