第１項記載の自動焦点カメラ。[Scope of Claim for Utility Model Registration] (1) Each time an externally operable photographic preparation switch is operated, a distance measuring means is activated, and furthermore, distance measuring information from this distance measuring means is collected while the above operation continues. A pre-focusing operation is performed which is held in the intermediate distance measurement information holding means, and then by operating an externally operable photographing execution switch, a focusing operation is performed using the final distance measurement information from the last pre-focusing operation. In addition, in an autofocus camera that performs a photographing operation that exposes a film, the distance measuring means that measures the distance to the subject and outputs the distance measurement information corresponding to the distance measurement means is approximately the same as the distance measuring means that is typified by commemorative photography. an externally operable mode changeover switch that switches between a commemorative photography mode and a normal photography mode in which a subject is photographed at least twice at a distance of Receives and stores the final distance measurement information from the last pre-focus operation performed before the operation is performed from the distance measurement information storage means, and at least finishes the second photographing operation under the commemorative photographing mode. Upon receiving the final distance measurement information from the distance measurement information storage means and the distance measurement information storage means, the mode changeover switch switches to the commemorative photography mode or normal photography mode. ranging information selection means for selectively outputting the final ranging information from the ranging information storage means or the ranging information holding means respectively when set to the ranging information storage means; and a lens drive control means for executing a focusing operation for driving and controlling a photographing lens to a focusing position corresponding to the final distance measurement information after the pre-focusing operation and before the photographing operation, and in the commemorative photographing mode. When the first photographing operation is performed below, the focusing operation is performed based on the final distance measurement information of the distance measurement information holding means, and then the second photographing operation is performed. is executed, regardless of the distance measurement information obtained by the pre-focus operation after the first photographing operation, the final distance measurement information is stored in the distance measurement information storage means prior to the second photographing operation. An autofocus camera characterized in that the above-mentioned focusing operation is performed based on distance measurement information. (2) After the mode switching means is set to commemorative photography mode, at least the first
The autofocus camera according to claim 1, which is a registered utility model, is configured to perform a second photographing operation subsequent to the second photographing operation, and automatically switch to the normal photographing mode when the second photographing operation is completed.
