Abstract

A phonograph record player mechanism includes a tone arm 14, means for mounting the tone arm for rotation about an axis, a cueing lever lift rod 596 adapted to engage the tone arm at a point spaced from the said axis, an effectively flat spring 590 having one end thereof connected to the lift rod, means defining a fixed shoulder 602 in engagement with one side of the spring, and a cueing lever 604 which is rotatable about a substantially horizontal axis and has a portion which engages the other side of the spring between the lift rod and the shoulder when the cueing lever is rotated about the said horizontal axis. <IMAGE>
