ABSTRACT:
The present invention relates to an integrated driving system for signal-processing devices, especially video devices (recorders), disk drives, and other, preferably magnetic pulse recording devices, wherein the device chassis (1) and the mounting provision for at least two motors (20, 21, 22) are formed integrally with each other. The device chassis (1) proper also includes all mounting or bearing bores (e.g. 2, 50, 55) for all mounting shafts (e.g. 4, 8, 18) in a precise positional relation to each other. The bores (2, 50, 55) for all mounting shafts (4, 8, 18) and axles are formed in the metal-cast device chassis (1) in one or more machining operations without the necessity of re-chucking, ensuring that not only the active and passive driving sections of the driving system, but also the reference surfaces and bearing or supporting points are precisely positioned relative to each other.
