Shingle media item feed tray with spring loaded self locking sled

摘要

A media item feed tray (102) with an exit area (108) for media items includes a sled (150) moveable toward and away from the feed tray exit area. A biasing surface is mounted to the tray and extends away from the feed tray exit area. A spring member (224) is mounted on the moveable sled (150) and is connected to the biasing surface such that when the moveable sled is moved away from the feed tray exit area energy is stored in the spring member (224). The biasing surface may be a shaped rail with a cam surface and the moveable member may include a cam follower which engages the shaped rail cam surface. A first cam section and a second cam section can be provided with the moveable sled urged toward the feed tray exit area when the cam follower engages the shaped rail first cam surface section and urged away from the feed tray exit area when the cam follower engages the shaped rail second cam surface section. A mechanism can be provided for locking the sled from movement and with a sled front face which can be positioned to facilitate loading of media items into the feed tray and positioned for media item feeding operation.
