Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
A portable data system including a rigid case having a lid (4) and a bottom plate (1) which carries a PC-computer (10) having a keyboard (11) and a thin liquid-crystal presentation screen (12) which can be raised and lowered relative to the computer and which in a lowered position forms essentially part of the upper surface of the computer, and a voltage source (29, 31) for powering the computer and the presentation screen, the system further comprising a carrier plate (26) which is intended to rest on the upper surface of the screen when the screen occupies its lowered position, and which carrier plate is movable upwards and away from the keyboard and the screen to a working position through the agency of two parallel-arm mechanisms (18-21) located on each side of the computer and on the bottom plate, and an ink printer (27) which is powered by said voltage source firmly mounted on the carrier plate, said printer projecting partially into the lid in a raised position thereof.
Claim 2
Dependent Claim
169 words
A portable data system including a rigid case having a lid (4) and a bottom plate (1) which carries a PC-computer (10) having a keyboard (11) and a thin liquid-crystal presentation screen (12) which can be raised and lowered relative to the computer and which in a lowered position forms essentially part of the upper surface of the computer, and a voltage source (29, 31) for powering the computer and the presentation screen, the system further comprising a carrier plate (26) which is intended to rest on the upper surface of the screen when the screen occupies its lowered position, and which carrier plate is movable upwards and away from the keyboard and the screen to a working position through the agency of two parallel-arm mechanisms (18-21) located on each side of the computer and on the bottom plate, and an ink printer (27) which is powered by said voltage source firmly mounted on the carrier plate, said printer projecting partially into the lid in a raised position thereof.
Claim 3
Dependent Claim
46 words
A system according to claim 1, wherein said voltage source comprises two rechargeable batteries mounted in the lid of the case and which form therebetween a space which freely accommodates the computer, the screen and the printer when the lid is lowered towards the bottom plate.
Claim 4
Dependent Claim
34 words
A system according to claim 2, further comprising a static converter (34) arranged in the case for supplying an operating voltage to the printer which is different from the operating voltage of the computer.
