FIELD: physics, optics.SUBSTANCE: disclosed optical sensitive device which, even if the frame is thin, can allow smooth withdrawal or entrance of the sensitive unit from and into the frame and can also compensate for the position shift of the display panel caused by actuation thereof and the resultant heat generation. The optical sensitive device 1 includes a frame 2 of a main housing, a sensitive unit 3 which includes an optical sensor 108, guide elements 16 configured to guide the sensitive unit 3 and drive means configured to move the sensitive unit 3 into a measurement position. The sensitive unit 3 is provided at both sides with movable elements 31. The sensitive unit 3 moves forward an inclined manner along inclined elements 162 which are made at the front parts of the guide elements 16, and a shadow element 9 located on the sensitive unit 3, which is in contact with the display screen 101a of the display panel. After measurement, the sensitive unit 3 moves back in an inclined manner and pushed into the frame 2 of the main housing.EFFECT: improved design.2 cl, 65 dwg |
