ABSTRACT:
A finger device freely loads the printing papers in a feed cassette. The finger apparatus includes a conductor protrusion coupled to a paper sensor at one side of a body where the cassette is attached and detached. The finger is supported by a pin and spring in the feed cassette for separating with a tray portion of the feed cassette. A finger portion of the finger apparatus can be located at an edge of the feed cassette by the projection of the body, upon the feed cassette being attached. The finger portion can automatically separate the feed cassette using a stability of the spring upon the cassette being detached from the body.
