Abstract: A transportable data system includes two units (3, 4) which are fitted in a rigid case which includes a lid (2) and a bottom part. When the lid is closed, the one unit (3), which is supported by a carrier plate, is located above the other unit (4), whereas when the case is open, with the lid substantially vertical, the one unit can be moved towards and partially into the lid, so as expose the other unit (4) and bring it to a working position. Provided are two separate side - walls (14, 15) which are fitted firmly to the bottom part (1), and each of which has an upper guide rail (6, 7). The guide rails are parallel with the bottom part and also with one another. Furthermore, the carrier plate (5) is displaceably mounted on the guide rails.

Abstract: A portable data system includes a bottom plate 1 and a lid 4. The bottom plate carries a PC-computer 10 having a keyboard 11 and a pivotal presentation screen 12 which in its lowered position forms part of the upper surface of the computer. The system also includes a voltage source for powering the computer and the screen. A carrier plate 26 is intended to rest on the upper surface of the screen in the lowered position thereof. The carrier plate is attached to the bottom plate by means of two parallel-arm mechanisms 18-21 arranged on each side of the computer. These parallel-arm mechanisms enable the carrier plate together with the printer 27 carried thereby to be moved away from the computer and partially into the raised lid.
