A camera holder 27 inserted into and fixed to the camera 25, and the camera (25) is inserted into the camera holder 27 and inserted into the front housing 21, and has a second engaging portion 28 protruding in a semi-cylindrical shape on both sides so as to correspond to the front housing 21. Oval so that the rear housing 29, the second coupling portion 28 of the rear housing 29 and the first coupling portion 24 of the front housing 21 can be inserted and fixed to the cylindrical coupling portion formed butt Plate spring 30 formed in an annular shape, a projection 31 protruding at an interval of 90 degrees on one surface of the elliptical plate spring 30, and inserted into the cylindrical coupling portion after the plate spring 30 to the main body Bushing 40 formed in an octahedral ring shape to be fixed to the part 70 and the projection 31 of the plate spring 30 is formed on one surface of the bushing 40 so that it can be slipped 90 A sliding groove 41 formed at intervals; It is composed of a camera cam 50 inserted and fixed to one side of the cylindrical coupling portion.

4A to 4D illustrate a main body 70 of the portable video terminal 100 according to the present invention. Referring to this, FIG. 4A shows a rear casing 71 having a rectangular shape. FIG. 4C shows a printed circuit board 73 made of various elements, and FIG. 4D shows an inverted reverse switch (mounted on top of the printed circuit board 73). 74 is shown.

5A to 5C show a plate spring 30, bushing 40 and camera cam 50 of the portable video terminal 100 according to the invention shown in FIG. 3C, and FIG. 5D is shown in FIG. 4D. Reverse phase inversion switch 74 is shown in a clear perspective view, respectively.

That is, the plate spring 30 of FIG. 5A is formed in an oval ring shape, and protrusions are formed at intervals of 90 °, and the bushing 40 of FIG. 5B is formed in an octahedral ring shape so that the sliding groove 41 is 90 °. At intervals, the sliding grooves 41 have their virtual extension lines meeting at the center of the bushing 40. In addition, the camera cam 50 of Figure 5c is formed in a ring shape, the center thickness of the ring is minimum at 0 ° and the angle is increased so that the depth of pressing the reverse phase reversing switch 74 according to the rotation angle As it grows larger, it is formed to be maximum at 180 °. In addition, the reverse portion reverse switch 74 of FIG. 5D has a contact portion 75 protruding from the upper portion so as to be in contact with the camera cam 50.

6A to 6C show when the camera unit 60 of the portable video terminal 100 according to the present invention configured as described above operates between 0 ° and 89 °; 7A-7C showing when operating between 90 ° and 180 °; And the relationship between the camera cam 50 and the reverse phase inversion switch 74 at the time of operation will be described with reference to FIG.

First, when the user rotates the camera unit 60 between 0 ° and 89 °, the camera cam 50 that rotates in the same manner rotates between the GH sections of FIG. 8, wherein the reverse phase reverse switch 74 is used. The contact portion 75 of the contact with the camera cam 50 is pressed by the AB section of FIG. That is, in this angle range (0 ° to 89 °), the switch does not operate and reverse phase inversion does not occur.

However, when the user rotates the camera unit 60 between 90 ° and 180 °, the camera cam 50 that rotates in the same manner rotates between the HI sections beyond the GH section in FIG. The contact portion 75 of the switch 74 is pressed by the BC section of FIG. 8. That is, in this angle range (90 ° to 180 °), the switch is operated to reverse the phase.

The portable video terminal 100 according to the present invention operated as described above, when the camera unit 60 is rotated between 0 ° and 90 °, as shown in FIG. When the camera unit 60 is rotated between 90 ° and 180 °, as shown in FIG. 9B, the camera unit 60 communicates with the state room while illuminating the rear side of the terminal 100. In this case, as soon as the camera unit 60 exceeds 90 °, the background is about to be reversed. At this moment, the background is illuminated by the operation of the reverse phase reverse switch 74.

As described above, the reverse phase inverting device of the portable video terminal according to the present invention instantly changes the reverse phase generated when the rotation angle of the camera unit 60 exceeds 90 ° to normal to enable smooth video communication between callers. This increases the reliability of the product.
