Title:
PICKUP DRIVING MECHANISM FOR LINEAR TRACKING PLAYER
Document Type and Number:
Japanese Patent JPS5764307
Kind Code:
A
Abstract:
PURPOSE: To horizontally drive a pickup through side pressure due to sound grooves activated to stylus, by driving a guide shaft of the pickup and making the friction between the guide shaft and the pickup as rolling friction.
CONSTITUTION: At playing, a belt 20 is belted on a pulley 8a fixed to a rotating shaft of a motor 8, pulley 17, pulley 19 fixed at one end of a guide shaft passing through a fixed plate 3a. Thus, the guide shaft 4 is driven and a dynamic friction smaller in friction value is always operated with a cartridge holding stand 6, and the horizontal drive of the cartridge 5 can be made with very small driving force. Thus, tracking operation can be made only with the side pressure of sound grooves of a record disc.
