Abstract
It is sought to simplify the arrangement of the drive power switching system for an acoustic apparatus, thus permitting immediate switching of the drive power. A drive power switching system comprises driven gears always in mesh with a main drive gear located between a first and a second gear and a rocking member rotatably supporting the driven gears. The inter-axis distance between the axes of rotation of the first and second gears, is set to a length, in which the driven gears can be meshed with both the first and second gears as they are revolved together with the revolution of the rocking member.
