Electronics unit, in particular a photo-composing unit

摘要

An electronics unit, such as a photo-composing unit (1), consists of a mechanical/electrical laser exposure device (illumination device) (2) and an electronics unit (3) which has an electrical power supply and base boards (8), such as databuses, which consume electricity. In order that all the structural units in the electronic appliance are screened against interference radiation and interference signals, and the antenna effect of cables is also reduced or even precluded, it is proposed that a power supply section (9) and at least one board rack (10) be arranged directly alongside one another, and that the connection to the power supply section (9) is in each case formed by busbars (11), in such a manner that two parallel busbars (11) for a voltage potential (11a) and for an earth potential (11b) run on the power supply section (9) and the board rack (10) arranged alongside one another on a line. <IMAGE>
