Claims

[Scope of utility model registration request]

In a camera in which a focusing operation and a shutter operation are sequentially performed in response to a release operation, and then a film winding operation, a shutter charging operation, and a focusing mechanism charging operation are performed almost chronologically by a motor. , an automatic focusing mechanism that drives the photographic lens system and stops the driving upon receiving a goldfish signal from the ranging circuit when the photographic lens system matches the in-focus position for the subject; a first operating member that operates in conjunction with the photographing lens system or the automatic focusing mechanism and continues to operate to release the shutter even after the automatic focusing mechanism stops driving at the in-focus position; a second actuating member, the second actuating member being engaged with the second actuating member so as to be actuable in the focusing actuating direction and inhibited in the opposite actuating direction, and charging the automatic focusing mechanism; an engaging member whose engagement is released at the end of the operating stroke, and a part of the second operating member or a member interlocking with the second operating member of H is arranged so as to face within the field of view of the finder. 1. A focus display device for an electric winding, automatic focusing camera, characterized in that focus result information is displayed within the field of view of a finder.
