Abstract

An arrangement for processing and modifying copy material for remote-controlled typewriters, in which a box-shaped frame holds the electronic circuit boards. The frame is provided with guides into which the circuit boards are inserted in a manner whereby the guides are open on both sides and to the rear. When inserted into the guides the circuit boards are located one above the other. The rear wall of the frame is rotatable upwards and has a window spanning substantially all of the circuit boards. A blower is connected externally to the window on the rear wall, and another window is provided in the region of the corner of the frame lying diagonally opposite the window on the rear wall. Both windows are of substantially the same height.
