Abstract

PURPOSE:To hold the relative position between a pickup arm assembly and a control coil accurately and stably, by providing the control coil to a coil fitting body at the fixed-side and by positioning a pickup cartridge at the coil fitting body. CONSTITUTION:Pickup cartridge 5 having built-up assembly 6 having a pickup element atop of pickup arm 12 and permanent magnet piece 14 at the base side is equipped and permanent magnet piece 14 is faced to control coils 20 and 21. Control coils 20 and 21 of the device are provided to fixed-side coil fitting body 8, and a means of positioning cartridge 5 at coil fitting body 8 of cartridge 5 when cartridge 5 is received and rotated as shown by arrow C until a prescribed position is provided. For example, side walls 10b and 10c of case 10 of cartridge 5 are provided with positioning notches 10b-1 and 10c-1 hooked with the collared small-diameter part of the bobbin of control coil 21, and height-positioning pins 24a and 24b are also provided on the top surface of coil fitting body 8.
