A device support stand has a base fixed to a device on which the support stand is installed, a first support shaft upstanding from the base, a second support shaft extended on a line perpendicular to the first support shaft and joined to the first support shaft via a first movable section, a third support shaft placed at a portion a predetermined distance away from the first support shaft, a fourth support shaft extended on a line perpendicular to the third support shaft and joined to the third support shaft via a second movable section, a pair of first and second connection frames joined to the fourth support shaft via third and fourth movable sections, respectively, and a device fixation member for device installation, installed on one end of the third support shaft. The first and second connection frames are joined together by adjustment/joint means for adjusting the spacing between the first and second connection frames so as to limit rotation of the first to fourth movable sections. The device on which the support stand is installed can be moved up, down, left, and right and can be fixed to a rear low position after changing its angle.
