Patent ID: 8348263

Claim:
A recording medium stacker that supports and stacks a recording medium discharged from a recording apparatus, the stacker comprising: a first stack member provided with a first support surface capable of supporting the recording medium; and a second stack member that is stored within the first stack member and can be pulled out of and pushed into the first stack member, and that is provided with a second support surface capable of supporting the recording medium when the second stack member has been pulled out of the first stack member and is in use, wherein the first stack member includes: a base end support surface in which the first support surface has a planar shape at a base end of the first stack member in a pull-out direction of the second stack member; and a leading end support surface that is formed continuously from the base end support surface to a leading end of the first stack member such that a radial curve is formed at a junction of the base end support surface and the leading end support surface so as to form a connected curved support surface, the leading end support surface forming a planar shape in which the leading end of the first stack member in the pull-out direction is sloped upward due in part to the radial curve, and the second stack member is held in a tilted orientation in which the second support surface forms a planar shape, and when in use, continues to the leading end of the second support surface in a tilted state with the same upward slope as the leading end support surface of the first support surface.
