摘要： An auto-focusing system includes a focus condition detector which detects focus condition based on the infrared light. A data producer is provided for producing a deflection signal indicating a difference between an image forming distance for the infrared light and that for the visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.

摘要： A photographic camera having in a patrone chamber for loading a film patrone a rotational drive mechanism for rotating a film in a direction for loosening at least the film peripheral relative to an axis along a patrone axis and extending toward a leading edge of the film and a film insertion mechanism for inserting the leading edge of the film into a film outlet opening extending from the patrone chamber to a film exposure section with the rotation of the film. With this construction, when the film patrone is accommodated in the patrone chamber, wherever the leading edge of the film may be placed about the patrone axis, the film insertion mechanism rotates the film about the axis along the patrone axis thereby to guide the leading edge of the film to be inserted into the film outlet opening extending to a manually-operated film winding-up mechanism or to an automatic film winding-up device.
