Description

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

  Some imaging 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 stored 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 a lens barrel is a small digital camera or the like having a relatively large diameter, so-called vignetting is prevented in which the irradiation light from the light emitting unit is blocked by the lens barrel and does not reach the subject. There is a need. Therefore, for example, in Patent Document 1, as a mechanism for moving the light emitting unit from the housing position of the apparatus main body to the light emitting position, the light emitting unit is mounted using a biaxial link mechanism in order to achieve both a compact housing state and a large protruding amount. Techniques have been proposed for positioning the subject higher than the main body toward the subject.

  In such a deployment mechanism, power supply to the light emitting unit is generally performed by a flexible substrate connected to the light emitting unit. A path of the flexible substrate connected from the light emitting unit to the inside of the apparatus main body is provided in a space between the link member and the flexible substrate protection member.

  The space in the height direction (vertical direction) occupied by the light emitting device in the housed state in which the light emitting unit is housed in the device main body is obtained by stacking the thickness of the light emitting unit, the link member, the flexible substrate path, and the protection member.

  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 to 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 at the time of storage / deployment increases, and it becomes easy to break due to fatigue. Problems arise.

  Accordingly, an object of the present invention is to provide a light emitting device and an imaging device that are downsized without reducing the strength of the light emitting device or increasing the bending load applied to the electrical wiring.

  In order to achieve the above object, a light emitting device according to the present invention is connected to a light emitting means, an electrical wiring connected to the light emitting means, the light emitting means via a first shaft portion, and the first shaft portion. And a first protection member and a second protection member that are thinner than the connection member and protect the electrical wiring. A part of the electrical wiring passes through a notch provided in the connecting member and is located between the first protective member and the second protective member.

  According to the present invention, it is possible to reduce the size of the light emitting device without reducing the strength of the light emitting device or increasing the bending load applied to the electrical wiring.

Is engaged. The second torsion spring 14 urges the light emitting portion 4 from the storage position toward the light emitting position around the first shaft portion 7 substantially parallel to the left-right direction of the camera body 1. In addition, the structure which moves the light emission part 4 to an accommodation position and a light emission position is not limited to said structure, The structure using the biasing member different from the structure which connected two link members, or a torsion spring may be sufficient.

  The light emitting unit 8 is connected to a flexible substrate 10 that is an electrical wiring that supplies power to the light emitting unit 8 from a power source in the camera body 1. An end 10 b of the flexible substrate 10 opposite to the end 10 a connected to the light emitting unit 8 is connected to a strobe driving substrate in the camera body 1.

  The link member 5 is provided with a notch 5a having a width H wider than the width of the flexible substrate 10 in a direction substantially parallel to the axial direction of the second shaft portion 6 and the first shaft portion 7. A part of passes through the space of the notch 5a.

  A first flexible cover 11 is provided on the front side and a second flexible cover 12 is provided on the rear side adjacent to the flexible substrate 10 that passes through the notch 5 a, and between the first flexible cover 11 and the second flexible cover 12. A path through which a part of the flexible substrate 10 passes is formed. That is, the first flexible cover 11 and the second flexible cover 12 serve to protect the flexible substrate 10. In the present embodiment, the link member 5 is thicker than the flexible substrate 10, the first flexible cover 11, and the second flexible cover 12.

  The first flexible cover 11 and the second flexible cover 12 are fixed to the link member 5 by screws 15 together. The fixing with the screw 15 is performed at a plurality of locations (for example, two locations) sandwiching the notch portion 5a near the end of the link member 5 on the notched side (upper side in FIG. 3). By fixing at such a position, the link member 5 can supplement the strength lost by the notch 5a with the first flexible cover 11 and the second flexible cover 12.

  4 is a cross-sectional view of the vicinity of the light-emitting device 2 showing the path of the flexible substrate 10 in the light-emitting device 2, FIG. 4 (a) is a cross-sectional view in a state where the light-emitting device 2 is located, and FIG. It is sectional drawing of the state located in FIG. The right side in FIG. 4 is the front side (subject side) of the camera body 1.

  In the storage position shown in FIG. 4A, the link member 5 is provided with a notch 5 a on the back side of the camera body 1 from directly below the light emitting surface 8 a of the light emitting unit 8. The position directly below is in the space of the notch 5a. That is, the light emitting part 4 and the notch part 5 a are arranged in the vertical direction of the camera body 1.
