There is described a strobe device particularly suited for image capturing apparatus equipped with wide-angle lens. The strobe device includes a reflector to reflect a strobe light, a light-emitting tube to emit the strobe light and an optical panel to transmits the strobe light. In the strobe device embodied in the present invention, a maximum luminous intensity of the strobe light, illuminated by the strobe device, is arranged in a direction being different from a direction of a strobe light axis.

Strobe device for image capturing apparatus, camera and lens fitted film unit, and reflector of strobe light

A strobe device, including: a strobe circuit board; a connecting conductor composed of a wire member; and a strobe emitting portion which includes; a) a light emitting tube, having electrode terminals on its both ends, b) a reflector for reflecting strobe light emitted by the light emitting tube toward a photographic object and c) a transmission window for covering a front surface of the reflector and for transmitting the strobe light. 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.

Strobe device of lens-fitted film unit and production method of the strobe device

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&plus;5.0 in EV value.

A single-use camera which includes: a film winding knob, capable of rotating in the winding direction, for winding a film so as to feed the film frame by frame; a reversion-preventing member, having an engagement with the film winding knob, for preventing the film winding knob from rotating in the opposite direction to the winding direction; a releasing member for releasing the engagement of the reversion-preventing member with the film winding knob when the film is wound by the film winding knob so that the noise, generated from the reversion-preventing member, is prevented.

A lens-fitted photographic film unit includes an electronic flash provided therein, a neon lamp to light or flicker when a charging voltage for the electronic flash reaches a predetermined value. A first window is provided on the upper surface or the rear surface of an external member of the film unit through which a light emitted from the neon lamp is observed, and a second window is further provided on the front surface of the external member through which the light emitted from the neon lamp is irradiated toward an object to be photographed. The film unit further includes a condenser lens provided between the second window and the neon lamp, to converge the light emitted from the neon lamp.

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.

Cylindrical type dry battery and battery chamber

In a single use camera in which an unexposed film has been loaded and which is sold together with the unexposed film, the camera comprises a strobe including an electric circuit, to irradiating a subject; and a camera body in which the strobe is incorporated, the camera body provided with a hole through which the function of the strobe can be checked.
