Abstract

A carriage (7) is fitted with wheels (8, 9) which roll on horizontal circular cross-section guide rails. Two wheels (8) are arranged in pairs with inclined axes so that the carriage is located laterally and the third wheel (9) is mounted on an eccentric (10) to allow adjustment of the lateral tilt of the carriage. Turned collars (3) which are an interference fit on the ends of the rails ensure that the latter are perpendicular to the end plates which support the arrangement on the baseplate. The interior of the carriage is cut out, leaving a support which supports the turntable drive motor so that it is the motor and turntable which move relative to a fixed reading head.
