Description

The present invention relates to a light emitting device in which a light emitting unit is rotatable.

Some image pickup devices such as digital cameras include a so-called pop-up type light emitting device that moves a light emitting unit between a storage position housed inside the device main body and a light emitting position protruding from the device main body.

By the way, in such a light emitting device, when the lens barrel is a small digital camera having a relatively large diameter, so-called vignetting, in which the irradiation light from the light emitting portion is blocked by the lens barrel and does not reach the subject, is prevented. There is a need. Therefore, for example, in Patent Document 1, as a mechanism for moving the light emitting unit from the storage position of the main body of the device to the light emitting position, the light emitting unit is provided by using a two-axis link mechanism in order to achieve both a compact storage state and a large protrusion amount. A technique for positioning the subject higher from the main body has been proposed.

In order to reduce the space in the height direction of the light emitting unit in order to supply a smaller camera, for example, it is necessary to reduce the thickness of the link member or narrow the flexible substrate path.

However, if the thickness of the link member is reduced, the strength of the light emitting unit during deployment cannot be maintained, and if the flexible substrate path is narrowed, the bending load applied to the flexible substrate during storage and deployment increases, and it becomes easy to break due to fatigue. Problems arise.

Further, the light emitting device according to claim 1 of the present invention is connected to the light emitting means, the electric wiring connected to the light emitting means, and the light emitting means via the first shaft portion, and is centered on the first shaft portion. It has a connecting member that is relatively rotatable with the light emitting means, and a first protective member and a second protective member that protect the electrical wiring, and a part of the electrical wiring is the connection. The first protective member is located between the first protective member and the second protective member through a notch provided in the member, and is located between the end of the notch and the electrical wiring. And one of the second protective members is located.
