  • Patent number: 7508439
    Abstract: Disclosed is a digital camera which does not need a dedicated exclusive lens barrier and permits use in compact states in normal photography. The digital camera comprises a camera body, a photographing lens which is provided on the front side of the camera body, an image display unit which displays taken images, and a movable unit which moves the image display unit between the front and rear positions of the camera body. The image display unit is set so that when moved to the front position, the display panel faces the front side of the camera body just like covering the photographing lens, and when moved to the rear position, the display panel is exposed.
