For example, the backlight is turned off when the sunlight is bright and the natural light taken in from the daylighting unit 4 is guided to the liquid crystal display device 3 as illumination light. Lighting.

[0007]

However, when the surrounding environment for taking a picture is dark or the like, the photographing operation may not be easily performed because the various operation terminals 5 may not be clearly seen during the photographing. . As described above, when the surrounding environment is dark, the backlight of the liquid crystal display device 3 is turned on, and the subject image is clearly displayed on the screen of the liquid crystal display device 3. On the contrary, the various operation terminals 5 are illuminated. Photo manipulation must be performed in this state without being dark, and the usability of photography is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a display device of a camera which can illuminate various operation terminals and facilitate photographing even in a dark surrounding environment.

[0009]

According to a first aspect of the present invention, there is provided a display device of a camera for illuminating a display device with at least one of light emitted from an artificial lighting device and external light taken in from a daylighting unit. It is a display device of a camera that illuminates light from an artificial lighting device leaking from a lighting part to various operation terminals of the camera.

According to a second aspect of the present invention, in the display device for a camera according to the first aspect, various operation ends of the camera are arranged adjacent to the lighting section.

According to a third aspect of the present invention, in the display device for a camera according to the first aspect, various operation ends of the camera are provided adjacent to the lighting section and on the side of the camera body where the display device is arranged.

According to a fourth aspect of the present invention, in a display device of a camera for illuminating a display device with at least one of light emitted from an artificial lighting device and external light taken in from a lighting portion, artificial lighting leaking from the lighting portion. This is a display device of a camera that guides light from the device to a display unit in the viewfinder.
