Abstract
An automatic patrone loading camera includes a patrone chamber, a rotating shaft, a detector, and a control section. The patrone chamber houses a patrone. A film is inserted in the patrone in the winding shaft direction while the film is wound around the outer surface of the patrone. When the patrone is housed in the patrone chamber, the rotating shaft is engaged with a winding shaft of the patrone so as to rotate the winding shaft. The detector detects an extracted state of a leader portion of the film. The control section controls a rotating direction of the rotating shaft on the basis of a detection value from the detector.
