Abstract

PURPOSE: To hold the vertical tracking angle constant even for camber, deformation, and so on of record discs, by providing a holding means, which holds the cartridge rotatably in the vertical direction, and a bias means which gives a prescribed mechanical bias to the cartridge.
CONSTITUTION: The dash pot consisting of cylinder 7, which is fixed to the tip of tone arm 5 through bush 6, and piston 8, which is fixed to the upper part of cartridge 1 and is inserted into cylinder 7, is used as holding means 4 of the pickup assembly. Spiral spring 13 is fitted to the tip of supporting axis 11 of tone arm 5 as an energizing means, and piston 8 moves vertically while receiving proper damping under the state where stylus tip 3 of cartridge 1 follows the surface of record disc 2, and thus, the vertical tracking angle is held constant.
