Abstract
Abstract A capstan housing assembly in a tape player device using an exchangeable cartridge includes a chassis having a cartridge support member having a support wall and first and second sidewalls, and a support plate precisely positioned with respect to the cartridge support member to define a cartridge receiving chamber. The support wall of the cartridge support member includes an opening therein adapted to receive a lower capstan bearing and the support plate includes an opening therein adapted to receive an upper capstan bearing. The support plate is mounted on the cartridge support member such that the lower and upper capstan bearings support and hold the capstan shaft in a predetermined position with respect to the cartridge receiving chamber.
