A zoom lens barrel includes at least two lens groups, a linear movement guide tube for guiding a linear movement of the lens groups along the optical axis and a cam tube for reciprocating the lens groups along the optical axis. The guide tube has a guiding portion formed on a film side end portion of the guide tube and extends in parallel with a film surface.

A zoom-type viewfinder device which has a multi-sectioned viewfinder cam which rotates in connection with the zooming of a photographic zoom lens. The viewfinder cam has a cam, with at least one cam bevel, which is divided into a first cam component and a second cam component. The first cam component and the second cam component are joined to connect the respective cam bevels to form a cam bevel which wraps more than once around of the cylinder of the viewfinder cam. As the viewfinder cam is manufactured in multiple segments, each segment can be removed from its forming die in the longitudinal direction of the viewfinder cam, thereby providing smooth zooming and a blur free viewfinder image. Also, the inclinations of cam bevels, which are formed on the viewfinder cam, can be made more gradual, which reduces the required driving force. Therefore, a more compact motor can be used, resulting in a more compact camera. Moreover, the power consumption required by the motor is reduced, increasing the life of the camera battery.

A viewfinder device having an optical path for viewing a photographic image includes a plurality of visual field frames. Each of the plurality of visual field frames define a photographic range. In addition, each of the plurality of visual field frames is positioned on one of a plurality of visual field frame display units. The plurality of visual field frame display units have overlapping regions and are positioned on a viewfinder mask member. The viewfinder mask member is movable in the optical path. The overlapping portions of the visual field frame display units reduce an amount of movement necessary to move the viewfinder mask member to position the visual field frames within the optical path.

A lens shutter camera has light emitting and receiving sections for obtaining distance information. An optical section for performing photometry in an object field is disposed in a space between the light emitting and receiving sections in an optical axis direction. An electric plate passes the space between the light emitting and receiving sections in the optical axis direction and electrically connects a shutter section provided in a lens barrel and a control section provided outside the lens barrel.

Camera having a built-in and self-contained flash sub-assembly. The camera includes a body having a movable cover member, and a flash device for illuminating a subject to be imaged. The flash device includes a light emitting unit, a capacitor for supplying electric current to the light emitting unit to emit a flash of light, and a step-up circuit which, in accordance with a power source such as a battery, etc., charges the capacitor. The light emitting unit, the capacitor, and the step-up circuit are disposed in the moveable cover member of the body. The flash sub-assembly also may be disposed within a pop-up/out flash type unit supported by a camera body.

A camera includes: a camera main body having a lens barrel; and a slide cover that moves relative to the camera main body between a camera non-use position at which the lens barrel, at least, is covered and a camera use position at which the lens barrel is exposed. And a sealed space is formed at the slide cover and a camera component is provided in the sealed space.
摘要:
Apparatus such as a flexible printed circuit board (FPC) for coupling two electronic components that are configured to move relative to each other such as within a multi-part slide-open type camera, multi-part micro-scope, a scanner device, etc., that includes a first end configured to be coupled to a first electronic component, a flexible connecting member emanating from the first end, and a second end at which the connecting member terminates and which is used to connect the flexible connecting member to a second electronic component. The connecting member includes a component surface used to communicate electrical signals between the fist electronic component and the second electronic component. The flexible connecting member has a shape that permits it to extend and retract in directions substantially perpendicular to the component surface. The shape also permits the flexible connecting member to be maintained in a single plane when in a fully retracted state.

An apparatus that can be loaded with a film cartridge provided with a light-blocking door for opening and closing a film intake/outlet slot, comprises an opening/closing mechanism that opens and closes the light-blocking door, a cartridge chamber where the film cartridge is housed, a cartridge chamber lid that opens and closes a cartridge insertion access of the cartridge chamber, an operating device that is capable of moving between a non-allowing position at which opening of the cartridge chamber lid is prevented and an allowing position at which opening of the cartridge chamber lid is allowed, and a locking mechanism that becomes displaced to a state in which the operating device is prevented from moving to the allowing position and to a state in which the operating device is free to move to the allowing position, with an operation of the opening/closing mechanism.
