る光透過性フイルムの位置検出装置。A device for detecting portions with different transmittances provided on a light-transmitting film is provided with a first optical sensor corresponding to the path through which the portions of the light-transmitting film with different transmittances pass, and detects the light transmittance. A second optical sensor is provided corresponding to the path through which the other part of the film passes, and a comparator is provided to compare the outputs of these two optical sensors, so that the part of the optically transparent film with different transmittance is connected to the first optical sensor. 1. A position detection device for a light-transmitting film, characterized in that the output of the comparator is inverted when the film reaches a position of a light sensor.
