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： 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： 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.
