(Embodiment 1)
FIG. 1 is a rear perspective view of the digital camera 1 according to the first embodiment of the present invention. The digital camera 1 includes a camera body 10 and a liquid crystal monitor 30. The camera body 10 includes a rear housing 11 on the back side. The liquid crystal monitor 30 is rotatably attached to the rear housing 11 via a hinge 20.

  The hinge 20 has two rotation axes. Therefore, the liquid crystal monitor 30 can rotate around the two axes of the hinge 20. A state in which the liquid crystal monitor 30 is rotated in a direction away from the camera body 10 is shown in FIG. As shown in FIG. 2, the liquid crystal monitor 30 can be rotated with respect to a rotation axis perpendicular to the rotation axis in the opening direction. The surface opposite to the display surface of the liquid crystal monitor 30 is a protective material. Therefore, by rotating the liquid crystal monitor 30 in the open state and returning it to the original closed state, the display surface of the liquid crystal monitor 30 can be arranged so that it can be seen from the back side of the camera body 1 as shown in FIG. It can also be arranged to face the back of the camera body 10. By disposing the camera main body 10 so as to face the back surface, the display surface of the liquid crystal monitor 30 is protected by a protective material, so that the display surface can be prevented from being damaged during carrying.

  Further, the digital camera 1 can capture an image even when the liquid crystal monitor 30 is opened. As shown in FIG. 2, the user can take an image while holding the digital camera 1 upward while looking at the liquid crystal monitor 30 by turning the liquid crystal monitor 30 downward. Further, if the liquid crystal monitor 30 is rotated, the user can take an image while holding the digital camera 1 in a preferred posture such as his / her lateral direction or downward.

  In this way, the digital camera 1 can shoot with the liquid crystal monitor 30 opened, but when it rains at that time, the flexible wiring board that electrically connects the liquid crystal monitor 30 and the camera body 10 to each other. In order to prevent getting wet, a rotating lid 41 is provided. As shown in FIG. 2, the rotary lid 41 is provided between the camera body 10 and the liquid crystal monitor 30, one end 41 a is rotatably provided on the camera body 10, and the other end 41 b is moved by the biasing force of the spring 43. The liquid crystal monitor 30 is biased. Accordingly, at least a part of the rotary lid 41 follows the rotational operation of the hinge 20 and always contacts the cover of the hinge 20 regardless of how the liquid crystal monitor 30 is opened. Thereby, it is possible to prevent rainwater from falling below the rotary lid 41.

  A hole 23 is provided below the hinge cover 21 that covers the hinge 20. Thus, even if water enters the hinge cover 21, the water that has entered is discharged from the hole 23. Therefore, even when it is raining, the user can open the liquid crystal monitor 30 and take an image.

  FIG. 3 is a cross-sectional view of the liquid crystal monitor 30 in a closed state. FIG. 4 is a cross-sectional view in a state where the liquid crystal monitor 30 is opened.

  The liquid crystal monitor 30 and members in the camera body 10 are electrically connected by a flexible flexible wiring board 50. The flexible wiring board 50 is disposed so as to pass through the vicinity where the hinge 20 is provided. Further, the rear housing 11 is provided with an insertion hole 11 a for inserting the flexible wiring board 50.

  The rotary lid 41 is disposed so as to cover the flexible wiring board 50 in the insertion hole 11a. One end side 41 a of the rotary lid 41 is attached to the rear housing 11 so as to be rotatable by a shaft 42. A spring 43 is also attached to the shaft 42, and one end of the spring 43 is fixed to the rear housing 11, and the other end is fixed to the rotary lid 41. With this configuration, the spring 43 biases the rotary lid 41 toward the liquid crystal monitor 30. Therefore, a part of the rotary lid 41 always abuts on the hinge 20 and covers the insertion hole 11 a and the flexible wiring board 50. Thereby, the rotating lid 41 can prevent rainwater from entering from the insertion hole 11a. Further, the rotary lid 41 can prevent the flexible wiring board 50 from getting wet with rainwater, and can prevent the flexible wiring board 50 from being corroded.

  A protrusion 20 a is provided at a location where the hinge 20 contacts the rotary lid 41. Thereby, since it becomes difficult to produce a clearance gap between the rotation lid 41 and the hinge 20, it is possible to further prevent rainwater from entering the insertion hole 11a.

  The insertion hole 11 a is covered by the rubber packing 60 on the back surface of the back housing 11. Thereby, even if water permeates into the insertion hole 11a, it is possible to prevent the water that has permeated into other members inside the camera body 10 from reaching. A state where the rubber packing 60 is covered will be described with reference to FIGS. 5 to 8 are perspective views of the rear housing 11 as seen from the back surface.

  As shown in FIG. 5, the flexible wiring board 50 connects the outside and the inside of the camera body 10 through the insertion hole 11 a. The insertion hole 11a is covered with a rubber packing 60 as shown in FIG.

  FIG. 7 is a perspective view of the rubber packing 60 as viewed from the surface that is in close contact with the rear housing 11. A recess is provided at the center of the rubber packing 60, and the rubber packing 60 is disposed so that the recess covers the insertion hole 11a. Ribs 61 are provided in at least a part of the periphery of the recess. The rib 61 has a projecting cross-sectional shape and is preferably triangular. The ribs 61 are provided in the vicinity of the peripheral edge of the recess.

  As shown in FIG. 8, the rubber packing 60 attached to the rear housing 11 is fixed so as to be pressed against the rear housing 11 by a fixing member 70. Thereby, since the rib 61 is crushed, a gap between the rubber packing 60 and the rear housing 11 can be eliminated, so that water can be prevented from entering the camera body 10 from the rubber packing 60.

  The digital camera 1 is an example of the camera of the present invention. The camera of the present invention is not limited to this, and may be a film camera, a movie, a camera-equipped mobile phone terminal, or the like as long as it has display means that can rotate with respect to the camera body.

In the first embodiment, the hinge 20 that supports the liquid crystal monitor 30 is provided below the liquid crystal monitor 30. However, the present invention is not limited to this, and the hinge 20 may be provided beside or above the liquid crystal monitor 30. However, when the rotating lid 41 is not provided, in particular, if the hinge 20 is provided below as in the present embodiment, the intrusion of rainwater into the insertion hole 11a is likely to occur. Therefore, the present invention is particularly effective for intrusion of rainwater when the hinge is provided below the display means.

  In the first embodiment, the rotary lid 41 is provided on the camera body 10 side, but may be provided on the hinge 20. Further, although the rotary lid 41 is attached to be rotatable by the shaft 42, it may be attached to be rotatable by other methods. For example, the rotary lid 41 may be provided on the camera body 10 or the hinge 20 via a member that can be elastically deformed. In the first embodiment, the rotary lid 41 is biased by the spring 43, but a biasing means other than the spring 43 may be used. For example, it may be biased by a rubber-like body.

  The insertion hole 11a is an example of a hole provided in the camera casing of the present invention. The flexible wiring board 50 is an example of the flexible wiring material of the present invention, but is not limited thereto.
