Abstract: A photographic camera of the type including a piezo-electric actuating element driven by energy accumulated in a capacitor for actuating a shutter wherein the piezo-electric element operates in stability to assure accurate appropriate opening and closing operation of the shutter of the camera and the capacitor is charged up rapidly to allow subsequent photographing operation to be done in a minute. In the camera, a charged voltage of the capacitor is checked several times to determine if it is sufficient to assure proper operation of the piezo-electric element, and if a then required level is not reached, then the capacitor is charged to the required voltage. While the capacitor is being charged, charging of a capacitor for a flash is inhibited.

Abstract: A camera having, in addition to a real focal length photographing mode, a pseudo focal length photographing mode, namely, a photographing mode in which a part of a photographed image frame of a film is printed at an enlarging ratio different from an ordinary enlarging ratio to obtain a print as if it had been photographed using a telephoto lens. It is provided with means for recording photographing mode information on a frame of a film when the pseudo focal length photographing mode is selected, and a control means which brings a flash light emitting device into an operable condition in response to the selection of the pseudo focal length photographing mode and which actuates the flash light emitting device in synchronism with release of the shutter. An optical axis of a photographing lens and a flash emission tube are spaced from each other, and the pseudo focal length photographing mode can be selected only when a negative film is loaded in the camera.

Abstract: A camera accessory is provided which allows a camera to photograph in a pseudo focal length photographing mode. In the pseudo focal length photographing mode, a portion of an image recorded onto a film is reproduced on a print with larger enlargement than a normal image. Therefore, a print can be obtained as if it has been printed from an image recorded on a film which had been photographed by an objective lens having a focal length longer than the actual focal length of the objective lens used. Thus, according to the camera accessory, photographing in the pseudo focal length photographing mode can be possible if used in a camera which is originally incapable of the pseudo focal length photographing mode.

Abstract: The photographic camera which prints a code signal representing printing information on a film is capable of selecting a real focal length photographing mode for printing a normal range of a frame, a plurality of pseudo focal length photographing mode each being different in pseudo focal length from the other, and a close-up photographing mode. Expousre condition is limited in accordance with the selected mode. Upon selection of the photographing modes, a code signal indicative of said selection is produced and printed between frames on the film surface. The film after photographing with this camera is subjected to printing by means of a printer which reads the code signal printed on the film surface, determines an exposure value in accordance with the code signal and determines an enlargement ratio.
