ABSTRACT:
A novel system, e.g., an audio cassette player, is provided herein. The system simultaneously provides mechanical motion driven by a rotatable drive shaft which is rotating at a continuous predetermined desired speed, and for generating a voltage output by an electrical generator having a rotor which is rotating at a continuous predetermined desired speed, the rotatable drive shaft being non-concentric with, being laterally-spaced-apart from, and being parallel to the rotor. The system includes a prime mover which comprises a windable driving spring, which, in turn, includes an interconnecting drive train for separately drivably connecting the driving spring both to the rotatable drive shaft and to the rotor of the electrical generator. The interconnecting drive train comprising a gear train, which has a driving section which is connected to the driving spring means and which is common for driving both the rotatable drive shaft and the rotor at the electrical generator. It also includes two driven sections which are laterally-spaced-apart from one another and which extend in parallel from the driving section. One of the driven sections is drivably-connected to the rotatable drive shaft. The other one of the driven sections is drivably-connected to the rotor of the electrical generator. A speed governor is included for controlling unwinding of the driving spring so as to cause the driving spring to drive both the rotatable drive shaft and the rotor of the electrical generator at the respective continuous predetermined desired speeds.
