Abstract A pickup cartridge encloses a stylus arm car- rying a stylus at one end thereof. The other end of the stying arm is secured to a connector plate via a compliant member. A spring releasably clamps the stylus arm in a retracted position. A pair of elastic straps extend be- tween a pair of spaced end ribs. The rear end of the car- tridge has a pair of hooks for releasably retaining the pair of spaced end ribs. The rear surfaces of the elastic straps are at a certain angle with respect to the front surfaces thereof. The connector plate is secured to the slanted rear surfaces of the elastic straps to establish an angular orientation of the connector plate relative to the cartridge so that, when the stylus arm is held in the retracted position in the cartridge, the compliant member is unstressed. The connector plate is adapted to be rotated upon reception of the cartridge in a player to permit the stylus arm to protrude outside the confines of the cartridge without stressing the compliant member. The clamping spring is locatable in one of three positions relative to the cartridge. In the top position, the clamping spring retains the stylus arm in the retracted position against a stop in the cartridge. The middle position of the clamping spring permits the stylus arm to protrude outside the confines of the cartridge. The bot- tom position is for manufacturing purposes. Means are provided for accurately positioning the cartridge in a compartment provided in the player. - 1 -
