Detail explanations of the constitutional structure under the present invention will now be discussed.

FIG. 1 is a perspective view of an automatic display stand under the first embodiment, and FIG. 2 is a cross-sectional view of the automatic display embodiment showing the inner state of a extendable pipe, and FIG. 3 and 3a show a cross-sectional view of a height control embodiment showing the telescopic mechanism of the pipes.

The present invention under the first embodiment comprise a rotating display plate (1) and a stable stand base (3) being combined with a supporting member (2) telescopically being adjusted by a height adjusting member (5), and a detector (6) being installed in the stand base (3) for actuating the display plate (1) in a spin motion when a viewer approaches.

Specifically, the embodiment includes the display plate (1) as the mentioned above being connected with a motor (4) located on the upper portion of the supporting member (2), the supporting member (2) operated by a slideable combination between an inner pipe (2a) and outer pipe (2b), and the height adjusting device (5) installed between the telescopic pipes actuate the height control of the display stand (2), and further a detector (6) installed on the surface of the

stand base (3) located at the low position of the supporting member (2) detects the approaches of the viewer to the display stand (2) and it actuates upon the motor (4) being connected between PCB (7) and the detector (6) so as to rotate the display plate (1).

According to the present invention, the power supply for actuating the motor (4) can be selectable for using the power of batteries (9) or an adapter (8) being equipped for the outer source of the electric power. The selectable use of the electric power as the combination of adapter (8) or the batteries (9) installed in the stand base (3) enhances more convenient and flexible use of the display stand under the present invention in accordance with the various purposes of a display stand.

According to the first embodiment of present invention, the height adjusting member (5) of the column stand for the optimal view depending on the article to be displayed is provided to achieve a desired length in an exact and convenient way under the telescopic operation of pipe and the extension pipe to a desired length in a fast and precise manner wherein the adjusted height can be stably kept against external impacts, and the length adjustment of an extension pipes can be simply achieved by means of the smooth operation.

Now, hereinafter, more detail structure of the height adjusting member (5) can be discussed. An actuating part (51) fixed on the upper part of an outer pipe (2b) being tightly combined with the stand base (3), an adjusting nob (52) slideably combined with the outer part of the actuating part (51) and the adjusting nob (52) is being resiliently combined with a spring (54) installed between a grip cap (53) and the actuating part (51).

By an optimal displacement along the pipe direction ouf the actuating nob (52), the inner part of the adjusting nob (52) comprising an actuating part (56) acts on-an actuating hole (55) formed on an actuating part (51) and provides a released space for a stopper (57) which is attachable and detachable with the groove (58, 58t) formed on the outer surface of inner pipe (2a) being slideable with the outer pipe (2b).

The stopper (57 being released and locked on the groove (58,

58') on the inner pipe (2a) through the actuating hole (55) of the actuating part (51) is ready to actuate by the movement of the actuating hole (55).
