Abstract: In a camera to which the present invention is applied, a camera body having a pop-up ST unit attached thereto is sandwiched between front and back covers. A plugged rubber arranged inside the back cover is pressed by a front cover rib provided on the front cover in the state in which the front and back covers are joined to each other, whereby the front and back covers are kept liquid-tight to each other. Moreover, an ST rubber arranged on the periphery of the ST body is pressed by the front cover rib in the state in which the ST body is sandwiched between the front and back covers, whereby the front cover, the back cover, and the ST body are kept liquid-tight to one another. Simultaneously, the ST rubber is pressed by a cover rib provided on the back cover, whereby the back cover and the ST body are kept liquid-tight to each other. Thus, the water-proofing function can be secured among the three members, that is, the front cover, the back cover, and the ST body.

Abstract: Light from a flash discharge tube is reflected in a forward direction by a concave mirror and further refracted to a negative direction by a projection lens. A trigger wire for triggering the flash discharge tube to set off emission is constructed of an elastic material. The flash discharge tube is retained, as an integrated combination, by a discharge tube mounting frame on which support axial parts are provided in a protruding manner, and these support axial parts are slidably and swingably fitted with slide slots of the casing which are provided along the optical axis, so that the flash discharge tube is arranged to be displaceable both in a direction of the optical axis of the flash light emission apparatus and at least in one direction in a plane perpendicular to the optical axis with respect to a relative position thereof to the concave mirror.

Abstract: A camera comprising a camera sheath composed of a front cover unit and a rear cover unit, a camera body supported in the camera sheath, and positioning mechanism for positioning the camera body with respect to the camera sheath without fixing them. The positioning mechanism is composed of a pair of protrusions protruding from the front cover unit and a pair of hole portions formed in a reinforcing plate unit of the camera body and capable of being fitted individually on the protrusions. A gap of about 1 mm or less is formed in the whole area between the camera body and the camera sheath except fitting portions including the positioning mechanism.

Abstract: A flood light includes a lamp that is located at a focus of a reflecting mirror having a reflecting surface whose cross-section is oval and partially arcuate. A concave lens having negative refracting power is disposed between first and second foci about which an elliptical reflecting surface of the reflecting mirror is disposed. Some light rays from the lamp pass directly from the lamp through the lens while other rays from the lamp are reflected by the mirror before passing through the lens. Generally speaking, on the upstream side of the lens, the reflected rays enter the lens outboard of the rays that pass directly from the lamp to the lens. This construction provides a small flood light that has a high optical output, and effectively uses bundles of rays emitted from the lamp to produce a luminous intensity distribution desirable as light for range finding.

Abstract: A range finding device for a camera comprises a range finding module including at least a range finding element, a first support member for supporting the range finding module, a second support member for rotatably supporting the first support member, a unit base for rotatably supporting the second support member, a first adjusting member, such as a screw, for rotatably adjusting the first support member provided in the second support member, and a second adjusting member, such as a screw, for rotatably adjusting the second support member. The first adjusting member is set relative to the unit base in a non-contacting fashion and the rotation adjustment by the first adjusting member is independent of, and exerts no influence over, the adjustment by the second adjustment member.

Abstract: In a camera having a camera body which includes a film cartridge compartment, a spool compartment, an exposure unit including a lens barrel, and a sheath component that covers the camera body, a flashlight emission unit and an electric circuit unit for activating the flashlight emission unit are both attached to the sheath component.

Abstract: An illumination device having a light-emitting tube and a reflector for reflecting rays of light irradiated from the light-emitting tube is designed so that the cross-sectional shape of at least one section of the reflector in a plane perpendicular to the axis direction of the light-emitting tube is different from the cross-sectional shapes of the other sections in the axis direction of the light-emitting tube.

Abstract: A camera lens driving device of the present invention drives the lens at a constant speed while pressing force applied to an operating member by the operator is below a predetermined value and controls the lens driving speed according to pressing force after it exceeds the predetermined value. The lens driving device comprises a photo-taking lens, an actuator for driving the lens, an operating member for specifying a direction in which the lens is to be driven, a pressing force detector for detecting pressing force applied to the operating member to produce a variable output, and a drive controller responsive to an output of the pressing force detector for outputting a drive signal to the actuator. The drive controller includes first and second comparators and a drive signal output circuit. In response to the operating member being pressed the pressing force detector outputs a drive control signal to the drive controller.

Abstract: A multipoint rangefinder employs a light-emission device including a package which has a plurality of light-emission elements contained therein and mounting terminals extending therefrom, the light-emission elements being arranged in a line crossing a dimension along which mounting terminals extend. If, in mounting the rangefinder in a camera, the light-emission elements are arranged obliquely, the dimension along which the mounting terminals extend is made to coincide, for example, with the horizontal dimension. This arrangement provides various remarkable advantages. For example, it helps to avoid a substantial increase in the height of the camera housing and attain an improvement in the compactness with which the camera components are mounted, thus proving effective in camera miniaturization.

Abstract: A camera includes a photographic optical system movable along its optical axis, and a cam ring rotatable about the optical axis of the optical system. When it is rotated by a motor, the cam ring moves the optical system to change the focal length thereof. Arranged at the outside of the cam ring are a viewfinder optical system, whose optical axis is parallel to that of the photographic optical system, and a strobe mechanism movable in a direction parallel to the optical axis of the photographic optical system. First and second cam portions are arranged on the cam ring and engage the viewfinder optical system and strobe mechanism, respectively, so as to move them along the optical axis of the photographic optical system, in association with the rotation of the cam ring.
