Cassette handling apparatus with improved control arrangement

Abstract

An edge loading cassette holder/loader utilizes an improved ejector/release control arrangement wherein the cassette is loaded narrow end first through a loading receiver opening into a holder/loader platform. The control arrangement includes a first pivotally mounted control arm that is biased to pivot the arm to partially eject the cassette for removal and that also functions as a release control member for the platform. A second pivotally mounted control arm that moves with the first arm and functions as a release member for the platform is also provided. The platform is pivotally movable between an upper loading position and a lower operative position wherein the cassette hub sprockets are engaged by transport drive spindles. The platform is biased to the lower operative position and is moved to the upper loading position by the second control arm. As the cassette is inserted into the platform, the cassette engages the first control arm and pivots the first and second control arms until the second control arm releases the platform to the lower operative position. In the operative position, the control arms are retained in the pivoted position by the platform. An ejection lever pivots the platform upward. At a predetermined pivoted position of the platform, the second control arm is released and the cassette is partially ejected out the loading receiver opening by the first control arm. A bumper is utilized to contact the cassette to prevent excessive ejection force.
