Abstract
The moving mechanism of a sheet feeding device has a first moving member and a second moving member. The first moving member is held in a position corresponding to the number of sheets supported by a sheet support member, and when moving in a specific direction can move the sheet support member in the separation direction away from a paper feed roller. The second moving member moves out and back through a specific range of movement in each revolution of the paper feed roller, engages the first moving member and moves the first moving member in the specific direction when moving out, and releases said engagement when moving back.
