Abstract: A method and apparatus for effecting photometry in an automatic exposure camera includes the provision of photometric means which determines the brightness of an image field. Upon depression of an operating button, photometry is successively made of the brightness of an object being photographed, utilizing the photometric means, and corresponding photometric values are derived. Each successive value generated replaces the value previously generated. The last value generated is stored for subsequent use upon release of the operating button.

Abstract: A method and apparatus for effecting photometry from plural points of an automatic exposure camera includes the provision of photometric means which determines the brightness of a relatively limited region of an image field. Photometry is successively made of the brightness of an object being photographed at a number of desired points thereon, utilizing the photometric means, and corresponding photometric values are derived. An average of these values is taken, and transmitted to exposure control means, thus effecting an exposure control in accordance with the average.

Abstract: A multi-mode camera is provided which permits a selection from among a plurality of photographing modes including an automatic mode, a manual mode, an average photometry mode and a spotwise photometry mode. The camera includes a photographing information display which is located within a finder and which is formed by a liquid crystal display panel. The display includes a plurality of display regions, which enable necessary and sufficient photographing information to be displayed within the finder during a particular photographing mode selected, by providing a bar representation in which display regions from one end of the display and extending to a point corresponding to photographing information are activated and providing a point display in which a selected display region is activated which corresponds to photographing information.

Abstract: For use with a camera which is adapted for use with at least two interchangeable lenses having different brightness levels, a switching assembly is provided to enable one of at least two focussing, photosensitive elements each associated with a different one of the lenses. The switching assembly comprises first means normally assuming a first predetermined position in which one of the elements is enabled for operation, said one element being effective to detect an in-focus position when a corresponding interchangeable lens is mounted, and second means adapted to be forcibly displaced from a position in which said one element is enabled to another position in which the other element is enabled for operation.

Abstract: A program EE camera comprises a stop control mechanism for defining the stop extent with a relatively low precision in a few stages according to an electric signal from a light-measuring circuit and a shutter speed control mechanism for controlling a shutter speed in accordance with the stop extent defined by the stop control mechanism.

Abstract: A tortion coil spring is charged with a driving force for rotation in response to a film winding operation. When a start position regulating member is released from the shutter driving member, the shutter driving member is rotated by the driving force, till it runs against a shutter speed determining member. During said rotation, a connecting mechanism connected to the shutter driving member to be forward and backward reciprocated by the rotation of the shutter driving member makes a forward motion. Two shutter sectors connected to the connecting mechanism are moved by the forward motion to increase the area of an aperture as an exposure hole for a pencil of rays at the fixed rate by the function of a speed control mechanism. After stopped for a fixed time in response to the brightness of the light reflected from a foreground subject, the rotation of the shutter driving member is resumed. When the shutter driving member is released from the shutter speed determining member.

Abstract: A photographic camera comprises a slide cover fitted to a camera body to be moved between a first position closing an object lens and main finder and a second position opening these members, and a protective douser fitted to the camera finder window when the slide cover is moved to the first position and to open the range finder window when the slide cover is brought to the second position.

Abstract: A camera includes a circuit which determines the level of a supply voltage and a self-timer delay circuit associated with an electrical shutter. The camera also includes an acoustic indicator which includes a pulse oscillator and a small size acoustic alarm unit and which operates to produce a sound substantially continuously to indicate the level of the supply voltage and to produce a sound intermittently in order to indicate that the self-timer is in operation.

Abstract: A photographic camera of an automatic exposure control type has an electrical shutter of electromagnetic release type and also has a front cover slidably disposed across the front surface of a camera body between a first position in which it closes a taking lens and a second position in which it exposes the taking lens. The camera comprises a first, a second and a third switch which are mechanically associated with the front cover, a rear lid of camera and a film winding mechanism of camera, respectively. The second switch may be replaced by a switch which is mechanically associated with a film frame counter. These switches are connected in an electrical shutter circuit in a manner such that a shutter release operation is disabled in the first position of the front cover, but is enabled in the first position of the front cover whenever the rear lid is opened, thus enabling a film loading operation.

Abstract: A suspension strap fastener for camera including a rear lid which is pivotally mounted on a camera body by means of a hinge comprising a core shank and a pair of hinge plates, is mounted on a portion of the shank which is not engaged by the hinge plates. The fastener is also formed with a connection with a suspension strap.

Abstract: A protective cover for taking lens of camera comprises a thin sheet which is bent to cover the front, the top and a top portion of the rear of a camera body and is mounted on the camera body so as to be slidable lengthwise thereof between a first position which it covers a taking lens and a second position in which it exposes the lens.
