Abstract

PURPOSE: To achieve the improvement in operating characteristic and photographic characteristic by dividing the lighting device to a light emitting part and a control box body and specifying their installation places.
CONSTITUTION: The control box body 12 which has a leg part 12a engaging to an accessory shoe as well as terminals connecting to terminals X, A, E and is provided therein with a supply battery 13, capacitor 14, light emitting circuit 15 and dimming circuit 16 is mounted to the accessory shos and the light emitting part 20 built in with a ring-form flash light emitting tube 17 is mounted to the front end outside diameter of a lens-barrel 18 and is connected to the flash light emitting tube 17 and light emission and dimming circuits 15, 16 by means of a connecting cord 21, whereby the lighting device is constituted. This results in the divided disposition of the lighting device to the lens barrel 18 and camera body 1 upper, improved operating characteristic owing to the weight balance of the entire part of the device, obviated deviation between the photometric part and photographing part and improved photographing characteristic.
