PROBLEM TO BE SOLVED: To provide a compact camera for paintings and calligraphy built in a liquid crystal projector that can prevent a lighting light from being imprinted. SOLUTION: Each of lighting sections 1, 1 is formed through the arrangement of 3-rows and 10-columns of white light emitting diodes each having a lens whose lighting angle is about 40 degrees. A light diffusion plate 2 is shaped to be an inverse quadrangular pyramid whose apex is a focus of an image pickup lens 4a to surround a field angle of the image pickup lens 4a without a bottom face where a rectangular glass original platen 3 is equivalent to the bottom face, the four side faces are shaped to connect four triangles each having a notch to avoid the image pickup lens 4a and the inner face with knurl is painted in white. Furthermore, a rectangular lighting light transmission notch window 2a is made nearly in the middle of narrow width faces of the light diffusion plate 2 opposed to each other. |
