Abstract

The adjustable typed viewing device includes a main body, a pupil distance adjustment unit setup on the main body, two sliders drawn by the pupil distance adjustment unit to produce displacement in opposite direction in towards or backwards, and two screen units interlinked to the sliders. Thus, manipulating the pupil distance adjustment unit makes the screen units adjust distance along a second axial direction. A height adjustment unit can drive the screen units ascent and descent along first axial direction. Focus control unit drives the screen units shifting backwards and forwards along a third axial direction. Thus, the screen units are suitable for user to view.

Description

technical field [0001] The invention relates to an optical appliance, in particular to an adjustable viewing device. Background technique [0002] As shown in Figure 1, there is an existing viewing device 1 that can be connected to a TV set, a VCR, a computer, a game machine, a DVD player, etc. The device 1 has a screen 101 connected to the front end of the frame body 2, and the frame body 2 is hung on the user's head so that the screen 101 can be positioned directly in front of the human eyes. [0003] Although this viewing device 1 can achieve the expected viewing purpose, in actual use, the problem that it cannot be used universally will occur because the user's pupil distance, focal length and face size are different, and the screen 101 cannot be adjusted. Contents of the invention [0004] The purpose of the present invention is to provide an adjustable viewing device that can be adjusted according to the needs of the user's interpupillary distance, focal length and ...
