Abstract

At one side the casing (10) is a location (11) for a data terminal (12) which has a VDU (13). Centrally to the terminal location, the casing has an aperture (14) with a size corresp. to that of the VDU. The data terminal is placed on the table in its location with the VDU fitting tightly in the aperture and facing inwards. In the casing are two mirrors (15,16), of which the first (15) is arranged at an angle of 45 deg. to the radiation from the VDU, so that light radiations from the VDU are angled at 90 deg. The second mirror (16) is placed in the opposite side of the casing, and likewise is inclined at an angle of 45 deg. in relation to the plane of an aperture (17) in that part of the casing. In the aperture is a screen (18) of opaque plastic which picks up the light radiations reflected by the mirrors. The screen views the VDU picture the right way up on its outside which is located in front of the operator position (20).
