According to the invention, the portable terminal comprises a central unit (1), a keyboard (2) and a screen (3). The keyboard (2) can be disconnected, whereas the screen (3) is connected to the central unit (1) by means of a hinge device operating at least one bent lever (22), of which one end is hinged onto a first side of the central unit (1), while the other end is hinged onto the screen (3). On account of the bent shape of the lever, the screen may be tilted against a second side of the central unit (1). The terminal, according to the invention, can consist of a microcomputer.
