[0003]

However, in a strobe device with a built-in camera, in which a strobe case is provided on a camera main body via a hinge shaft, the rigidity of the hinge shaft is not sufficient when the length of the strobe case is increased. The length of the strobe case is set to be short because it may be damaged if an external force is applied to the strobe case. As a result, since the strobe is located near the taking lens of the camera body when strobe light is emitted, there is a drawback that the red-eye phenomenon occurs.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a strobe device with a built-in camera capable of reducing the red-eye phenomenon by taking a long strobe case.

[0005]

In order to achieve the above-mentioned object, the present invention provides a built-in strobe device in which a strobe case is provided on a camera body so that the strobe case can be raised and lowered via a hinge shaft. With the strobe case,
It is characterized in that the linking mechanism is constituted by a slider member and a linking link, and is reinforced and linked.

[0006]

According to the present invention, the hinge shaft between the camera body and the strobe case is reinforced by the link mechanism connecting the camera body and the strobe case. As a result, in the present invention, the length of the strobe case can be made longer than in the conventional case, so that the red eye phenomenon can be reduced.
