摘要： A lens-fitted photo film unit includes a flash emitter for emitting flash light toward a photographic object in flash photography. A flash amount control circuit quenches flash emission of the flash emitter when a value of integration of light reflected by the object as measured by a first sensor in the flash photography comes up to a predetermined level. An aperture stop device designates one of a large aperture state and a small aperture state. A switch disables the flash amount control circuit if the small aperture state is designated, and enables the flash amount control circuit if the large aperture state is designated. The switch regulates operation of the flash amount control circuit in order to raise an amount of the flash light at a time of the flash photography in the small aperture state.

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 data-imprinting apparatus for preventing the imprinting of incorrect dates in a lens-equipped film unit that lacks a monitor display unit for the confirmation of the date display. The lens-equipped film unit 1 contains a built-in data module 27 that lacks an external display unit that allows the confirmation of the date display from the outside. The data module 27 contains a transmission-type liquid crystal display unit 45 that automatically updates and displays dates based upon a pre-stored calendar. In the liquid crystal display unit 45, external light enters from the light collection window 15 on the front cover 12, thus creating a beam of data light. The data light, acting in concert with the shutter release operation, is guided into a dark box. The image-forming optical system that is provided in the dark box forms an image of the data light on a part of the photographic film. When a temporary disruption of the power supply from the battery 70 occurs due to vibrations, for example, the power supply monitoring circuit 75 that is incorporated in the data module 27 detects the event, transmits the off-mode signal to the LCD driver 73, and causes the display on the liquid crystal display unit 45 to enter into a non-display state.

摘要： In a flash circuit of a flash device, a Zener diode (37) is connected to a tap point (23f) located at an intermediate position of a secondary coil of an oscillation transformer (23). The oscillation transformer (23) and an oscillation transistor (22) constitutes an oscillation circuit. A potential at the tap point (23f) changes proportionally to a voltage charged in a main capacitor (41). When the main capacitor (41) is charged up to a set voltage, the Zener diode (37) conducts a Zener current, which activates a stopping transistor (38) and thus deactivates the oscillation circuit. When a flash charge switch (51) is turned on, an end of a light guide portion of a charge condition indicator (60) protrudes out of a lens-fitted film unit. When the main capacitor (41) is charged up to the set voltage, a light emission element starts lighting, and the light from the light emission element is projected from the end of the light guide portion.

摘要： An electronic flash device equipped with LED indicator for providing an indication of completion of charging a main capacitor and a circuit for lowering power consumption has a controlling transistor operative to control a base current of the oscillating transistor which increases or decreases a primary current flowing through a primary winding and to be turned conductive by a current supplied from a battery through a current limiting resistor to start supply of the base current of the oscillating transistor. A secondary current generated in a secondary winding increases the base current of the controlling transistor, which increases the base current of the oscillating transistor which is lowered by the current limiting resistor having a large resistance and is increased or decreased by the controlling transistor. The electronic flash device can lower the power consumption as compared to the conventional devices which use a tertiary winding to increase or decrease the base current of the oscillating transistor. A tertiary winding of the electronic flash device is solely used for turning on LED.

摘要： In a flash device, a three-terminal switch is provided for connecting or disconnecting between a secondary coil of an oscillating transformer and a base of an oscillating transistor, between the secondary coil of the oscillating transformer and a triggering capacitor, and between the triggering capacitor and a primary coil of a triggering transformer. When the three-terminal switch is turned on, a biasing current is supplied to the base of the oscillating transistor, so a current flows through a primary coil of the oscillating transformer, and a secondary current from the secondary coil of the oscillating transformer is supplied to the main capacitor through the three-terminal switch and a base-emitter circuit of the oscillating transistor, to charge the main capacitor. The secondary current is also supplied to the triggering capacitor through the three-terminal switch, to charge the triggering capacitor. When a triggering switch is turned on while the three-terminal switch is on, the triggering capacitor discharges current through the primary coil of the triggering transformer, generating a triggering voltage for a flash discharge tube. If the three-terminal switch is turned off, the biasing current and the secondary current are cut from the oscillating transistor, and the triggering capacitor cannot discharge.

摘要： A lens-fitted photo film unit contains a cartridge shell into which an IC memory is incorporated, and a roll of photo filmstrip having a magnetic recording layer. Unit ID data and date-of-manufacture data are written in the IC memory in the factory. A data recording circuit is provided on a flash circuit board. The data recording circuit is connected to the IC memory through a printed circuit board mounted to a cartridge chamber of the film unit. A finder mask and a photo sensor for detecting the position of the finder mask are mounted in the film unit. The photo sensor is connected to the data recording circuit, to write photographic data corresponding to the output of the photo sensor in the IC memory at each exposure. Before printing, the data written in the IC memory is read to be recorded on the magnetic recording layer of the photo filmstrip by use of an external recording device which is connectable to the IC memory through an interface terminal which is exposed to an exterior of the film unit.
