Description

ABSTRACT:
A panoramic camera has masking plates selectively movable for masking the exposure aperture so as to form a picture frame of a panoramic size or for opening the whole exposure aperture. A plate actuating mechanism provided on the fixed lens mount selectively sets the masking plates in either the full size position or the panoramic position. According to a preferred embodiment, the camera has a taking lens of the collapsible mount type having movable and fixed lens mounts. A guide groove formed on the movable lens mount engages with a pin formed on an operating knob upon retracting the movable lens mount into the fixed lens mount. The masking plates are thereby retracted from the path of the movable lens mount. The camera includes spring members for biasing the masking plates toward the full size position. An indicator indicates the frame size upon operating the operating knob. The operating knob is arranged in a film passageway for operating the plate actuating mechanism. The frame size is thereby prevented from changing until unloading the film. Two recesses corresponding to the two frame sizes are provided in a slide lever portion formed on the operating knob. A positioning projection formed on the back door engages with either of the arresting recesses so as to keep the slide lever portion at the position of the selected frame size. The camera further includes a mechanism for recording predetermined data on a portion of the film masked by the masking plates.
