摘要： A flash device for a lens-fitted photo film unit pre-loaded with unexposed photo film is provided. A main capacitor stores charge. A flash emitter emits flash light. A flash circuit board charges the main capacitor, and drives the flash emitter by discharging the main capacitor in response to an exposing operation. A tightly closed flash case is secured to the lens-fitted photo film unit, for containing the main capacitor, the flash emitter and the flash circuit board. Also, the lens-fitted photo film unit includes a sync switch for generating a trigger signal in response to the exposing operation. Two switch contact points are disposed outside the flash case, for receiving the trigger signal from the sync switch. The two switch contact points disable discharge of the main capacitor while the flash case is away from the lens-fitted photo film unit, and are short-circuited for discharge of the main capacitor upon supply of the trigger signal while the flash case is secured to the lens-fitted photo film unit.

摘要： A first stop plate with a small stop opening is disposed behind a taking lens, and a second stop plate with a middle stop opening is disposed between a first and second lens, which comprise the taking lens. Upon moving a changeover knob to an ON position, a flash unit and the second stop plate are actuated such that the middle stop opening is retracted from an photographic light path PL. The small stop opening is retracted from the photographic light path PL when subject luminance is less than a predetermined value. In high-luminance condition, the small stop opening and the middle stop opening are set on the photographic light path PL, and in middle-luminance condition, the small stop opening is retracted. In low-luminance condition, the middle stop opening is retracted by operation of the changeover knob, so only a large stop opening is set on the photographic light path PL.

摘要： In a film unit, a charge operation member is held on a fron side of a guide member to be slidable between an ON position to turn on a flash charge switch of a built-in flash device and an OFF position to turn off the flash charge switch. The guide member is mounted stationarily to a front side of a flash circuit board of the flash device. Joints between front and rear cover of the film unit are set away from those circuit portions of the flash device where high voltage current flows. The flash charge switch is constituted of a metal contact blade and contact chips provided on the flash circuit board. The metal contact blade is bent roundly at a base portion of a pair of resilient arms. The charge operation member keeps on pressing the arms onto the contact chips in the ON position. The flash device charges a main capacitor while the flash charge switch is on, and automatically stops charging when the charge voltage goes above a predetermined voltage. A light emitting diode indicates the completion of charging.

摘要： A lens-fitted photographic film unit has a picture frame size changing mechanism for changing the size of picture frames between a full size and a panoramic size. The picture frame size changing mechanism includes upper and lower exposure aperture masking plates which are pivotally mounted in a light-shielding box in front of an exposure aperture. The masking plates are interconnected to each other through one-side contact and urged by a tension spring toward a full size position. The upper masking plate is connected to an operation knob through a crank lever and a switching lever. When the knob is operated to select the panoramic size, the switching lever is moved over a necessary amount for moving the masking plates in a panoramic size position to mask the exposure aperture. After the masking plates are stopped in the panoramic size position by stoppers, the over-stroke of the switching lever is absorbed by resilient bending of the crank lever.

摘要： A lens-fitted photo film unit has an electronic flash device (11, 30; 115) with a printed circuit board (173). The flash device includes a flash-emitting section (6, 170) for emitting flash light toward a photographic field, and a main capacitor (31, 155) for storing charge to be discharged in the flash-emitting section. The printed circuit board converts a current of a battery (12, 127) into a current of high voltage to be supplied to the main capacitor. The printed circuit board has a transistor (13, Tr1) for oscillation. A primary winding (15) has one end connected to the battery, and another end connected to a collector of the transistor. A secondary winding (16) is combined in mutual induction with the primary winding, has one end connected to the main capacitor, and another end connected to a base of the transistor. A tertiary winding (17) is combined in mutual induction with the secondary winding, has one end connected to the battery, and another end connected to the base of the transistor. An LED (21, 180) has a cathode connected to the one end of the tertiary winding with the battery, and an anode connected to the another end of the tertiary winding opposite to the battery. The LED is driven to emit light in response to charging of the main capacitor at a predetermined level. In a preferred embodiment, the photo film unit is pre-loaded with photo film (123) having speed of ISO 800 or higher, to allow the main capacitor to have small capacitance adapted to the high speed of the photo film.

摘要： A continuous taking camera has a plurality of exposure chambers disposed linearly. Two shutter discs rotated by a motor are provided at the back of the exposure chambers. Each shutter disc is formed with two movable shutter openings at positions different in distance from the axis of rotation of the shutter disc. When the motor is energized by a shutter release operation, the motor causes the two shutter discs to perform one rotation for sequentially opening and closing the exposure chambers starting from an outermost exposure chamber. A 35 mm full size original frame is divided in the longitudinal direction of the film into four sub-frames. Scenes for eight sub-frames are taken using two full size original frames.
