To provide a system for controlling the charging of a secondary battery (battery), which is capable of keeping an initial charging/discharging characteristic of the battery in consideration of a change in environmental temperature and deterioration of the battery with elapsed time. An ordinary charging portion for performing a first charging control specified to stop the charging at a charge level less than a full-charge level is used in combination with a refresh charging portion for performing a second charging control specified to stop the charging at a charge level more than the full charge level. After the charging by the ordinary charging portion is continuously repeated by a specific number of times, for example, ten times, the next charging is performed by the refresh charging portion. The cut-off voltage used for the ordinary charging portion and refresh charging portion is determined by correcting a reference voltage VO on the basis of an environmental temperature TAO detected by an environmental temperature detecting portion. The deterioration of the battery is corrected on the basis of a reference full-charge voltage, an initial full-charge voltage Vmax(1), a present full-charge voltage Vmax(n), an initial maximum battery temperature Tmax(1), and a present maximum battery temperature Tmax(n).

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.

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.
