Abstract

A monitor apparatus including a monitor and a base to support the monitor. The monitor apparatus further includes a first link provided between the monitor and the base; a second link provided between the monitor and the base adjacent to the first link; a base bracket combined to the base having first and second lower supporting parts to rotatably support lower parts of the first and second links, respectively; a connecting bracket rotatably combined to the monitor having first and second upper supporters to rotatably support upper parts of the first and second links, respectively. A first spring is interposed between the first link and the first lower supporting part to elastically bias the first link upward with respect to the base; and a second spring is interposed between the second link and the second lower supporting part to elastically bias the second link upward with respect to the base, where the distance between rotating axes of the first and second lower supporting parts, on which the first and second links are rotatably supported, respectively, is greater than the distance between tilting axes of the first and second upper supporters. Accordingly, the present invention provides a monitor apparatus in which a monitor can be adjusted in both height and a tilting angle as desired, where the height of the monitor is adjusted while keeping the tilting angle thereof in an angle suitable for a user to view the screen.
