Abstract: A camera capable of recording information uses a film cartridge that includes a spool for rolling a film that includes a data recording portion. A pair of elastic flanges having annular lips peripheries thereon are provided on the spool for nipping successive convolution of the film. The film is propelled out of the cartridge by rotating the spool in a predetermined direction. The camera further comprises a feeding member for winding the film fully when the cartridge is loaded into the camera and rewinding the film into the cartridge in response to the completion of a film exposure. A recording means is also provided in the camera. The rewinding means serially records the information onto the recording portion of the film when the film is rewinding.

Abstract: A camera using films each having a development processing solution in a solution accommodating bag includes rollers feeding photographed film outside of the camera or into an accommodating chamber, a piezoelectric press member held between an electrode and an elastic member also serving as an electrode presses photographed film and spreads development processing solution in the solution bag over an entire exposing portion. A piezoelectric member vibrated by AC voltages applied to the electrode and elastic member reduces a frictional force of the film caused by the press member. The processing solution is heated by vibrating the press member to generate heat.

Abstract: A data printing apparatus of this invention controls the emission timing or the emission interval of a light-emitting means on the basis of a signal according to traveling of a sheet film along a traveling path so as to print data free from blurring of characters or a variation in interval between characters on the sheet film having no perforations. After an exposure operation is ended, the apparatus feeds the sheet film from an exposure position along a spool wall. Light corresponding to digital numerals representing a date is emitted by light-emitting elements, and the date to be printed by the light-emitting elements is focused on the sheet film by an optical system. The date on the sheet film is printed during traveling of the sheet film along the spool wall.

Abstract: A flash apparatus which is detachably mounted on a camera main body is operated in a light emission mode of an open control scheme, in which the light emission amount of the light-emitting portion is controlled by a preset guide number, and in a light emission mode of an automatic control scheme, in which the light emission amount of the light-emitting portion is controlled by a metering result obtained by metering light reflected by an object to be photographed. The flash apparatus includes one of the following switches a bounce state detection switch which is turned on when the light emission axis of the light-emitting portion is inclined with respect to the optical axis of a photographing lens, an OFF-camera detection switch which is turned on when the flash apparatus is to be used while it is detached from the camera main body, and a converter mounting detection switch which is turned on when a converter is mounted on the photographing lens.

Abstract: An automatic focusing camera includes a sensor for detecting an amount and a direction of difference between an image forming position of light from an object being photographed and a film surface to drive a taking lens in response to the measured outputs and focus determining capability which gives a decision of in-focus when the amount of difference is less than a first automatic focusing threshold. A focusing operation is achieved such that, comparing the amount of difference determined by the sensor with a second automatic focusing threshold of a standard value which is larger than the first automatic focusing threshold, when the amount is less than the second threshold and a direction of difference last measured and that presently measured are the same, a taking lens driving is continued to complete a focusing operation and when the directions are different from each other, the measurement is resumed after the next driving of the taking lens even when the amount is less than the second threshold.

Abstract: A program rewritable camera includes camera elements for conducting camera operation, a control circuit for controlling said camera elements in response to coded control orders, a first memory for storing said control orders and an input circuit for enabling part or all of the contents stored in said first memory to rewrite by a peripheral device disposed outside the camera body. Connecting the peripheral device to the camera, camera functions desired by a photographer can be transferred to and stored in said first memory from the peripheral device in which various camera functions have been stored, through said input circuit to put the camera into action.

Abstract: An automatic focusing camera, after determining composition of an object being photographed within a range finding frame disposed at the center of a finder, repeats operations of detecting a range difference between an image forming position and a predetermined focusing position of the object and of storing the detected range difference, before a shutter release button is half-depressed, and, after being half-depressed, drives a taking lens in accordance with a range difference based on the latest information stored immediately before the half-depression to stop the taking lens at the predetermined focusing position, thereby enabling the lens setting without a time lag even when the object being photographed is in a low brightness.

Abstract: Apparatus for delivering distance information of a camera includes counter means which counts a relative distance corresponding to a movement of a taking lens. The counter means is reset when the taking lens reaches a reference position located at infinity. Using stored data (absolute distance factors) which is specific to a taking lens and the count in the counter means, an absolute distance is derived.

Abstract: A lens barrel is capable of selectively establishing a power focus mode in which an internally housed motor moves a taking lens to a position of any desired focal length, a single "auto-focus" mode in which the taking lens is moved to a position which is in focus to a stationary object being photographed, and a sequence "auto-focus" mode in which the taking lens is continuously moved in focus to a moving object being photographed. Any one of these modes is suitably selected by a mode changing switch. A movement of the taking lens in each mode is initiated by an operating member.

Abstract: A focussing apparatus for a camera is provided including a focussing light source for directing focussing light toward an object being photographed, and an in-focus detector circuit for receiving the focussing light as reflected by the object to determine a focussing condition. A light source control circuit is provided which deenergizes the focussing light source in response to an in-focus detection signal fed from the in-focus detector circuit.

Abstract: A burner for a bottom fired, ingot heating furnace producing faster and more even heating with lower fuel consumption is disclosed. The burner includes a plurality, preferably three, upstanding nozzles having nozzle ports directed at essentially a right angle to a radial line extending from the burner center. This orientation imparts a circular swirling action of the combustion gases which produces faster and more even heating of ingots contained within the furnace. The nozzle is arranged with a nozzle cap which shields the entire nozzle top from debris falling from the furnace roof resulting in a greatly extended service life.
