Problems solved by technology

However, since the charging operation will not stop until the user returns the charging operation member to the OFF position, if the user forgets to turn off the flash charging switch, the battery will run out of power and the flash operation will not be possible.
[0008] At the same time, if the user accidentally drops the photographic device with the built-in flash device into the seawater, the seawater will seep into the photographic device
Due to the conductivity of sea water, if the main capacitor of the flash unit is charged at that time, the charging current will leak through the sea water

Abstract

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.

Description

technical field [0001] The present invention relates to a photographing device with a lens equipped with a built-in flash, wherein a flash unit having a flash charging button and a flash projector constitutes an assembly on a flash circuit board. The invention also relates to a flash device for a photographic device or camera with a lens. Background technique [0002] The well-known lens-mounted photographic device has a simple exposure device, and an unexposed film cassette is installed in the factory so that anyone can take pictures without having to think about installing and rewinding the film. Hereinafter, a camera equipped with a lens will be simply referred to as a camera. [0003] Currently, there are many photographic devices on the market that have a built-in flash so as to be able to take pictures in the dark. The photographic device mainly has a body consisting of a rear cover for accommodating a roll of unexposed film and a main body, an exposure device with a...
