In a camera system of this invention, a light beam coming from a photographing lens is reflected by a quick return mirror in the widthwise direction of a body unit, and is reflected by a second mirror via a half mirror and screen in the upward direction of the body unit except for some light beam components. The light beam reflected by the second mirror is reflected by a third mirror in a direction opposite to that of the light beam reflected by the quick return mirror, and is also reflected by a fourth mirror toward an eyepiece side in the back side of the body unit. Some light beam components reflected by the half mirror are fetched by an AF sensor unit to detect the focal point position of the photographing lens.

Camera having optical viewfinder

A camera having a lens barrel housed therein includes a reflection optical member for reflecting a light beam incident along a first optical axis (O) from a subject so as to reflect the light beam toward a second optical axis (O) intersecting the first optical axis; a light-quantity adjusting member for adjusting the quantity of incident light from the subject; and a drive source for displacing the light-quantity adjusting member, in which by displacing the light-quantity adjusting member, the quantity of the incident light from the subject can be adjusted, and the light-quantity adjusting member is displaced in a direction substantially perpendicular to an optical axial plane inclusive of the first optical axis and the second optical axis so as to adjust the light-quantity.

Camera

A camera is provided which includes a camera main body, a first cover covering one side of the camera main body, a second cover covering the other side of the camera main body, an appearance surface formed on an exterior of the camera main body and positioned between the first and second covers when the camera main body is held between the first and second covers to produce an appearance of the camera, and an operation member arranged on the appearance surface.

Camera having operation member

A camera is provided which has a back cover for opening and closing an aperture, a spool chamber and a cassette chamber. A battery chamber for housing a battery is disposed on a supporting shaft side of the back cover, and the aforementioned battery chamber is present obliquely behind the cassette chamber inside the camera when the back cover is in a closed state. A part of the battery chamber protrudes from the back face of the back cover. Therefore, the exterior shape of the camera can be miniaturized and downsized without hindering loading of a film cassette. Further, since the battery chamber portion protruding from the back cover can be made to function as a grip portion of the camera, a camera superior in portability and favorable in holdability is provided.

Camera having a miniaturized exterior shape

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.

Water-proof structure of camera

To keep a flexible printed substrate planar when the substrate is set in a mounter for mounting parts and to miniaturize the substrate, the present invention proposes an electric substrate, for example, a flexible printed substrate on which electronic parts are mounted, the electric substrate having a first area a part mounting area) formed therein, a second area ( part mounting area) formed therein, and a third area ( a separable area) that joins the first and second areas like a &ldquo;bridge&rdquo; and that can be removed when the substrate is assembled into predetermined equipment, the third area having a positioning hole (one of a set of positioning holes) for use in mounting electric parts on the substrate.

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.

Flood lamp with improved light energy utilization

An electric circuit board system for a camera includes at least one main electric circuit board having a central processing unit for performing a control of a camera, and at least one connection section for having an electric connection with other electric circuit boards. A plurality of unit circuit boards can be connected with the above-described at least one connection section, with mutually different specifications. Any one optional unit circuit board is selected from the plurality of unit circuit boards and is connected to at least one of the main electric circuit boards, for structuring a camera.

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.

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.
