Abstract: A photographic camera having also a function of panoramic photographing includes a panorama switch which is turned ON to change over the mode of photographing to the mode of panoramic photographing and to activate a drive motor to forcibly move an objective along the optical axis to the minimum focal distance position. A slidably movable knob member serving for switching of the photographing mode is provided laterally of a viewfinder, and a photographing mode display appears on the external surface of the camera as the knob is slidably moved to select the mode of panoramic photographing. When the mode of panoramic photographing is selected and the panorama switch is turned ON, a liquid crystal display unit adapted to display various data including a film frame count displays the camera mode of panoramic photographing. A sighting frame for normal photographing and a sighting frame for panoramic photographing are both arranged within the viewfinder frame.

Abstract: A variable focal length camera has a lens barrel movable parallel to the optical axis of its taking lens system so as to change over the focal length of the taking lens system at least between a standard photography position and a telephoto position. When the subject distance is nearer than the nearest focusable distance for standard photography or for telephotography, the lens barrel is automatically moved into a first close-up position if the lens barrel has been in the standard photography position, whereas the lens barrel is moved into a second close-up position if the lens barrel has been in the telephoto position.

Abstract: A lens driving apparatus is provided with an encoder for detecting the position of a taking lens system. The encoder has a contact array including a main contact corresponding to a predetermined focal length position of a taking lens system and a sub-contact which is spaced slightly from the main contact. When a focal length changeover switch is operated to set the taking lens system in the desired focal length position, a motor is driven at a high speed until the sub-contact is detected and thereafter is driven at a low speed until the main contact is detected.

Abstract: A camera comprising a main body section and a rear cover section each having at least one microcmputer therein, and comprising a film rewinding switch disposed in the rear cover section for rewinding a loaded film at an appropriate time. A device is provided, for checking whether the microcomputers in the main body section and the rear cover section can communicate with each other. If the communication between the microcomputers is not possible, the film is rewound independently of the film rewinding switch.

Abstract: A photographic camera with changeable focal length has a reversible motor used both to wind and to rewind a film and also to move a taking lens in order to shift it between first and second photographic modes. A lens barrier is caused to open and close by a barrier operating member, for protecting the taking lens, and by a motor control circuit. The circuit includes two changeover switches one of which is connected to one of two motor terminals, an encoder connected to the other motor terminal for shifting the circuit between a film drive mode selected when the taking lens is in either one of the two modes and a taking lens drive mode upon changing the taking lens between the first and second modes. The encoder has first and second mode selecting contacts at which the encoder stops the motor to select the first and second modes, respectively.
