Abstract: PROBLEM TO BE SOLVED: To provide an image pickup mechanism and a projection mechanism and also to miniaturize a device by providing an image pickup device and a liquid crystal display panel on the same base plate where their positions are also movable and moving their positions with a common means. SOLUTION: A CCD 2 of an image pickup device, an aperture 6 and a liquid crystal display panel 5 that covers the aperture 6 which are separated from the CCD 2 at an angle of 180 deg. are placed on a base plate 3 which is disk like and is rotated by a motor 4. The CCD 2 is faced an image pickup lens 1, and an image signal into which image light that comes from the lens 1 is photoelectrically converted by the CCD 2 is recorded in a video cassette loaded in a video deck part 10 after the picture signal is undergone signal processing. Also, the plate 3 is turned a half circle by the motor 4 so that the panel 5 may face the lens 1, and an image recorded in the video cassette is reproduced and showed on the panel 5.  Thereby, when a light source 7 is lighted up and the panel 5 is irradiated with projecting light, image light is transmitted through the lens 1 and projected, an image that is picked up can be seen without using a TV set, and this device can be miniaturized.
