Abstract
A video disc player includes a carriage supporting signal processing circuitry having an electrical input terminal. A pickup cartridge which is removably mounted in said carriage contains a stylus and an electrical connection between an electrode on said stylus and a terminal on the cartridge. The cartridge terminal engages the input terminal of the signal processing circuitry under operating conditions. During installation of the cartridge in the carriage, cartridge projections cooperate with cam surfaces provided in the carriage to hold the terminal on the cartridge in spaced relation to the input terminal until the two terminals are aligned, to prevent a shearing motion therebetween.
