发明名称 Detection device and method to locate film
摘要 A detection apparatus for locating a film position detects the position with a simple structure. The apparatus uses a plurality of position detection holes for each picture frame in a film. The holes are repeatedly formed in the film in a certain arrangement and correspond to detection bodies located in the camera. The device includes a signal output circuit generating signals indicative of the proper or improper positioning of the film based on alignment between the holes and the detection bodies.
