[0029] Figure 1 to Figure 3 A first embodiment of the flash device of the present invention is shown. In the above-mentioned drawings, reference numeral 11 denotes a holder for a flash device. The main body of the flash device is fixed on the bracket 11 . The stand 11 has a stand main body 13 , an outer member 15 , and an operating device 17 . Figure 16 It is a perspective view showing a state in which the flash unit of the present invention is attached to the camera stand socket (accessory socket) 19 .

[0030] The bracket body 13 is made of metal such as iron and copper alloy. The stand main body 13 has an insertion device 13a inserted into the camera stand socket 19, and a support device 13b formed integrally therewith at right angles to the insertion device 13a. The upper part of the supporting means 13b is bent at a certain angle to form a mounting part 13c for fixing the main body part 1 of the flash device.

Abstract

The invention provides a device installed in an accessory socket on a main body device, comprising an inserting device inserted into the accessory socket, a moving part, an operating part, and a moving device for moving the moving part through the operation of the operating part. The structure of the mobile device is such that when the insertion device is inserted into the accessory socket and fixed, a part of the mobile part can be pressed against the inner wall surface of the accessory socket; The condition on the inner wall surface of the socket.

Description

technical field [0001] The present invention relates to a device mounted in an accessory receptacle on a main body device and to a camera accessory. Background technique [0002] As is well known in the prior art, a flash device used for mounting in a camera stand socket is known, for example, the flash device disclosed in JP-A-9-43683. In the flash device, a locking nut is arranged on the bracket of the flash device. When the bracket is inserted into the bracket socket, by rotating the locking nut, the specially arranged locking bolt will protrude from the bracket and be locked in the bolt hole specially arranged on the bracket socket. [0003] But, there is following problem in the above-mentioned existing flash device, in order to fix the flash device on the bracket socket of the camera, there must be bolt holes corresponding to the locking bolts of the flash device bracket on one side of the bracket socket, and the flash device It is very difficult to fix to a normal c...
