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.
