Various embodiments of a height adjustment device for an imaging apparatus are provided. In one embodiment, the height adjustment device (100) has a driving shaft (110), first and second moving bodies (120, 130) and a driving means (140). The driving shaft (110) is rotatably installed in a main body (11) of an imaging apparatus (10). The driving shaft has a first spiral groove (111) having a first pitch (P1) and a second spiral groove (112) having a second pitch (P2) on a peripheral surface thereof. The second pitch is different from the first pitch. The first moving body is screw-engaged to the driving shaft in the first spiral groove, while the second moving body is screw-engaged to the driving shaft in the second spiral groove. The driving means rotates the driving shaft. A control panel (12) and a display device (13) of the imaging apparatus are coupled to the first and second moving bodies, respectively.
