摘要

The device has a housing arrangement (2) containing a computer (3) and at least one mechanism for using one or more data memory devices. There is at least one operating keyboard (5) which is connected to other functional blocks via a system bus (12). The bus is coupled to a central unit (9), a control unit (10) and an update unit (11) for ROM.
