Abstract
Provided is a dual display device for a camera apparatus having a projector therein, which includes a rotary mirror module configured to project light of the projector to a front side of the camera apparatus body to display the light to the outside or to a rear side of the camera apparatus body while being rotated by driving of a drive motor.
Claims14
A dual display device for a camera apparatus having a projector therein, comprising:
- a camera apparatus body having a front side and a rear side;
- a rotary mirror module installed within the camera apparatus body and disposed on a front side of the projector, the rotary mirror module being configured to project light of the projector to the front side of the camera apparatus body to externally display the light or to the rear side of the camera apparatus body while being rotated by driving of a drive motor;
- a light guide module installed within the camera apparatus body and configured to refract and enlarge the light projected to the rear side of the camera apparatus body by the rotary mirror module;
- a reflective mirror installed in the light guide module and configured to reflect the light toward a screen;
- and
- the screen installed in the camera apparatus body and configured to display the light reflected by the reflective mirror,
- wherein the projector has a projection lens that linearly moves towards and away from the rotary mirror module,
- wherein the light guide module comprises a first light guide installed at a location corresponding to the rotary mirror module and configured to focus the light introduced through the rotary mirror module, and a second light guide formed in the first light guide and installed at a location corresponding to the screen, and
- wherein the second light guide has a light guide plate configured to reflect the light introduced into the first light guide using the reflective mirror and display the reflected light on a front surface of the screen.
