Paper feeding cassette for a printing apparatus

Claim 1

A cassette for storing and supplying a sheet of a recording medium to a printing apparatus having a controller for formatting the printing on said sheet, comprising a frame having a bottom and upwardly extending sidewalls, a movable longitudinal guide on said bottom, said longitudinal guide being adjustable to the length of said sheet, first and second movable horizontal guides on said bottom, said first and second horizontal guides being adjustable to the width of said sheet, means for linking said first and second horizontal guides together so that they move symmetrically with respect to a longitudinal central axis of said frame when they are adjusted to the width of said sheet, said longitudinal guide and said first and second horizontal guides being adjustable to the dimensions of said sheet independently of each other, said longitudinal guide and said first and second horizontal guides cooperating to closely receive said sheet within said frame, first sensing means associated with said longitudinal guide for sensing the position of said longitudinal guide, first connecting means for connecting said first sensing means to said longitudinal guide so that said first sensing means travels along a first predetermined path in conjunction with movements of said longitudinal guide, second sensing means associated with said first and second horizontal guides for sensing the position of said horizontal guides, and second connecting means for connecting said second sensing means to said first horizontal guide so that said second sensing means travels along a second predetermined path in conjunction with movements of said first horizontal guide, wherein the format of the printing on said sheet is controlled by the positions of said longitudinal and horizontal guides.
