ABSTRACT:
A photocopier tray cassette lift plate is lockable against the upward bias of its springs by a tab extending down to engage a lower latch member mounted to the tray base. The lower latch member is spring biased toward a position in which it may engage the tab, and is movable toward a disengaging position by a forwardly projecting surface that engages the photocopier frame upon insertion of the tray.
