In the strobe device, the connecting conductor has a contact with the light emitting tube and electricity is supplied to the light emitting tube through the connecting conductor.

Abstract: A lens-fitted film unit and production thereof, wherein lens-fitted film unit has a front cover, a rear cover, a main body and a magazine chamber lid to take out a film magazine from a film magazine chamber located in the main body, below the film magazine chamber and at the bottom surface of the lens-fitted film unit. The front cover, rear cover and main body have respectively a rib, and the surrounding of the lower portion of the film magazine chamber is surrounded by the rib of the front cover, the rib of the rear cover and the rib of the main body. After the rear cover is attached, the film magazine chamber lid is attached so that the magazine chamber lid is fixed to the front and rear cover and is not fixed to the main body.

Abstract: A lens-fitted film unit including a main body; a photographic film, pre-loaded in the main body; an electronic flash unit; a shutter unit; a camera lens; and a diaphragm. In the lens-fitted film unit, a guide number of the electronic flash unit, a T-number determined from the camera lens and the diaphragm and a shutter speed of the shutter unit are determined so that A is not more than 8.5 when A represents an EV value of a reference exposure amount of the lens-fitted film unit under a stroboscopic photographing state minus 1.5; and intensity of a latent image, formed on the photographic film under the condition that a reference reflection panel being placed at a predetermined distance between 2-3 m from the lens-fitted film unit is illuminated by the electronic flash unit without other lights in the stroboscopic photographing state, corresponds to intensity of a latent image obtained under a photographing condition of photographing luminance not more than A+5.0 in EV value.

Abstract: In a lens-fitted film unit with a built-in strobe, when photographing is conducted with strobe light, a strobe unit takes a first attitude in which a strobe panel is directed to a subject being photographed, while when photographing is conducted without the strobe light or when photographing is not conducted, the strobe unit takes a second attitude in which the strobe panel is directed almost downward, a strobe frame is rotated so as to change from the first attitude to the second attitude or from the second attitude to the first attitude, a portion or an entire portion of a print base board is located beneath the strobe panel when the strobe unit takes the second attitude, a front cover has a protruded first wall section to hide at least the portion of the print base board located beneath the strobe panel when the strobe unit takes the second attitude.

Abstract: A one-time-use camera comprising a film cassette having a light lock pivoted open to permit film movement into the cassette interior and pivoted closed to prevent ambient light from entering the cassette interior and a locking pawl movable into engagement with the light lock when the light lock is closed to secure the light lock closed and movable out of engagement with the light lock when the light lock is closed to permit the light lock to be pivoted open, is characterized in that a driver is moveable in engagement with the light lock to pivot the light lock closed to allow the locking pawl to move into engagement with the light lock and has a void which prevents the driver from moving the locking pawl out of engagement with the light lock, whereby the driver can be pushed against the film cassette to push the film cassette out of the camera without any possibility of the driver being moved in engagement with the light lock to pivot the light lock open.

Abstract: A dry battery includes a cylindrical housing, a first end plate and an electrode. The electrode protrudes from the first end plate and includes a tip end plate and a cylindrical side wall. The cylindrical housing, the first end plate, the tipe end plate and the cylindrical side wall each made of a conductive material are electically connected with each other so as to form a first conductive surface. A first contactor of an electrical power source circuit is arranged to come in contact with a part of the first conductive surface other than the tip end plate.

Abstract: A photographic roll film cartridge in which a roll film is stored in an initial packaged condition before being used for photographing. In the initial packaged condition, the leading edge portion of the roll film protrudes out of the cartridge by a length of 10 mm to 25 mm.

Abstract: A camera for accommodating a film cartridge which includes a film being rolled on the axis in a lightproof condition. The camera includes; a cartridge chamber for receiving the film cartridge in the axial direction; an ejecting member for ejecting the film cartridge which is placed in the cartridge chamber; and a positioning member for positioning the film cartridge at a fixed position in the cartridge chamber; wherein the positioning member includes an engaging claw which is interchangeable between a first condition that the engaging claw is movable by a pressing force of the film cartridge while the film cartridge is inserted into the cartridge chamber by an operator, and a second condition, after insertion of the film cartridge into the cartridge chamber is completed, that the engaging claw is pushed by a spring member so that the engaging claw engages with a side end of the film cartridge.

Abstract: In a lens holding device, a plurality of protrusions of equal height are provided oppositely at the front and rear of the periphery of a plastic photographic lens. The plurality of protrusions are substantially equidistant. Three sets of stairs, each having a plurality of steps with a predetermined difference in height between adjacent steps, are provided at positions corresponding to the protrusions in a lens receiving member and a lens pressing member, between which the lens is sandwiched. The position of the lens can be adjusted from a most advanced position to a most retreated position along the optical axis by selecting a preferred step of each of the stairs.

Abstract: A foldable camera for self-developing film comprises a base housing and a movable member pivotable between a closed position integrated with the housing and an open, elevated position above the housing. The movable member is mounted to a supporting member which is pivotally coupled to the housing at the end opposite from the film exit end of the housing. An objective lens and a reflex mirror are fixedly mounted to the movable member in fixed relationship to each other such that they are in the proper positions for film exposure when the movable member is pivotted to the elevated position.

Abstract: A photographic camera having an integral timepiece includes a case adjustable between an open condition for use as a camera capable of recording data and a collapsed condition in which the camera elements are concealed from view and only an external time display is visible.

Abstract: There is disclosed a release device of a camera simple in structure and enabling the camera of "one shot" and successive photographings.The release device comprises a conventional self-cocking mechanism and a locking and unlocking member in addition. The locking and unlocking member is operated by a member movable in response to film winding operation and actuates a shutter release member to release the release member when the film winding operation is completed.

Abstract: A camera provided with a device for recording the ambient light in photographed scene on a photosensitive material. In this light recorder built-in camera, the light of a main light source is projected and recorded at a position corresponding to an object image-projected face of a color film and when a color print is formed from a positive color photosensitive material, by using the density of the light of the main light source obtained by subjecting the color film to a development treatment, exposure quantities of blue, green and red colors are determined.
