Abstract
A paper tray for a photocopier comprises a container (1) which can travel between open (E) and closed (L) positions. It moves along guides (22, 24). A drive mechanism (32) move the container from the closed to the open position by exerting a constant force on the container. The container is mounted on a carriage (20). This is supported by a pair of transport rollers (28) which roll along the guides. The rollers (28) are firmly connected together for rotation by a shaft (30). A locking mechanism is provided for the container. A lever (54) is rotatable on the photocopier to lock the container in the closed position. The lever is coupled to a slide (60) having a cam groove (65) therein. This is arranged to move a locking element (55) which engages the lever (54) so as to release the lever (54) as the container is pushed further into the photocopier in the closed position.
