Abstract

A mobile TV receiver is provided in which the viewing screen can move left and right or up and down and be tipped or tilted by remote control as the viewer chooses. The TV receiver is divided into a head portion including a CRT-tube and a lower body portion accommodating driving elements and supporting the head portion. The head portion is adjustably connected to the upper part of the supporting body portion so that only the head can lean over, tilt up and down, and move upward and downward by operation of the driving elements under the viewer'"'"'s control. The viewer can thus remote-control the TV set back and forth, and adjust it exactly as desired to make the TV screen comfortably visible.
