Abstract
Abstract A device for rotating a liquid crystal display coupled to a camcorder, capable of safely protecting the liquid crystal display, eliminating any protruded portion of the camcorder, and rotating the liquid crystal display in any directions, thereby taking a moving picture at any positions of the camcorder. The camcorder includes a lens barrel longitudinally extending through an upper portion of an interior of the camcorder body, the lens barrel having a plurality of lenses, an outer lens mounted to one end of the lens barrel, a cylindrical slip ring fitted around an outer surface of the lens barrel, a rotating body fitted around the end portion of the lens barrel surrounded by the slip ring between the outer lens and the camcorder body such that it can rotate about the lens barrel, a rectangular liquid crystal display coupled to the rotating body, the liquid crystal display having the same width and thickness as those of the rotating body, and a liquid crystal display rotating unit for rotating the liquid crystal display with respect to the rotating body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A camcorder comprising: a camcorder body; a lens barrel longitudinally extending through an upper portion of an interior of the camcorder body, the lens barrel having a plurality of lenses; an outer lens mounted to one end of the lens barrel; a cylindrical slip ring fitted around an outer surface of the lens barrel; a rotating body fitted around the end portion of the lens barrel surrounded by the slip ring between the outer lens and the camcorder body such that it can rotate about the lens barrel; a rectangular liquid crystal display coupled to the rotating body, the liquid crystal display having the same width and thickness as those of the rotating body; and liquid crystal display rotating means for rotating the liquid crystal display with respect to the rotating body.
Claim 2
Dependent Claim
132 words
A camcorder comprising: a camcorder body; a lens barrel longitudinally extending through an upper portion of an interior of the camcorder body, the lens barrel having a plurality of lenses; an outer lens mounted to one end of the lens barrel; a cylindrical slip ring fitted around an outer surface of the lens barrel; a rotating body fitted around the end portion of the lens barrel surrounded by the slip ring between the outer lens and the camcorder body such that it can rotate about the lens barrel; a rectangular liquid crystal display coupled to the rotating body, the liquid crystal display having the same width and thickness as those of the rotating body; and liquid crystal display rotating means for rotating the liquid crystal display with respect to the rotating body.
Claim 3
Dependent Claim
73 words
A camcorder in accordance with claim 1, wherein the liquid crystal display rotating means comprises: a stopper adapted to control the rotation of the liquid crystal display carried out about a bundle of connection lines extending between the rotating body and the liquid crystal display, the stopper having a protrusion protruded from one surface of the stopper; and a stopper guide provided with a guide slot for guiding the protrusion of the stopper.
Claim 4
Dependent Claim
42 words
A camcorder in accordance with claim 2, wherein the guide slot has an unlooped construction having opposite ends not connected with each other so that it prevents the liquid crystal display from rotating through an angle corresponding to one rotate or above.
Claim 5
Dependent Claim
72 words
A camcorder in accordance with claim 1, further comprising: connecting pins disposed in an interior of the rotating body beneath the slip ring and coupled to a connection circuit board for amplifying an image signal, the connecting pins being constructed to be in slidable contact with the rotating body and rotate together with the connection circuit board during a rotation of the rotating body at a fixed state of the slip ring.
Claim 6
Dependent Claim
25 words
A camcorder in accordance with claim 4, wherein the connecting pins are made of a material exhibiting a good conductivity and a good contact property.
Claim 7
Dependent Claim
53 words
A camcorder in accordance with claim 1, further comprising a hand holder mounted to one side surface of the camcorder body and adapted to enable a user to shoot a moving picture of an object under a condition that he holds the camcorder body in his one hand held by the hand holder.
Claim 8
Dependent Claim
116 words
A camcorder in accordance with claim 1, further comprising: a slip ring mounted to an area between the rotating body and the liquid crystal display; a pair of stoppers respectively mounted to the area between the rotating body and the liquid crystal display to control the rotation of the liquid crystal display with respect to the rotating body and an area between the outer lens and the rotating body to control the rotation of the rotating body with respect to the outer lens, each of the stoppers having a protrusion protruded from one surface of the stopper; and a pair of stopper guides respectively provided with guide slots for guiding the protrusions of the corresponding stoppers.
