Test firing of a photographic flash assembly

A method of test firing an electronic flash in a camera during manufacturing assembly of the camera, in which the flash capacitor is pre-charged to an intermediate voltage level which is insufficient to test fire the flash using an external power supply. According to the present invention, the flash...

Zusammenfassung:	A method of test firing an electronic flash in a camera during manufacturing assembly of the camera, in which the flash capacitor is pre-charged to an intermediate voltage level which is insufficient to test fire the flash using an external power supply. According to the present invention, the flash capacitor is then fully-charged to a level which is sufficient to test fire the flash, using the battery contained for the camera, and the flash is test fired. According to a preferred embodiment, the flash assembly is mounted within a camera body, and a front cover covers the flash. A set of holes in the front cover are accessible to allow fast charging of the flash capacitor during assembly of the camera.
