Abstract

Heretofore, some copy output stackers on wide format copiedprinters that are used to copy engineering drawings have included a stacking device that has a tray with a fixed depth. This type of stacking device made stacking multiple length copy sheets impractical. Other copy sheet stacking devices require an operator to make multiple manual adjustments to adjust the size of the stacking device according to the size of original documents being fed into the machine. In order to make the operator more efficient and the copying process less labor intensive, a need exists for an improved copy output stacking device.

Heretofore, some copy output stackers on wide format copiedprinters that are used to copy engineering drawings have included a stacking device that has a tray with a fixed depth. This type of stacking device made stacking multiple length copy sheets impractical. Other copy sheet stacking devices require an operator to make multiple manual adjustments to adjust the size of the stacking device according to the size of original documents being fed into the machine. In order to make the operator more efficient and the copying process less labor intensive, a need exists for an improved copy output stacking device.

A copy sheet stacking device for stacking a variety of wide and long copy sheets without operator involvement is shown in FIG. 1. The copy sheet output device 10 is adapted to gather the output copies from a machine as they exit the front of the machine, and stack them in the same order as the sequence of originals or as the images are presented by a printer. The copies within the stack can be random in size, ranging from "A" to "E" size, and be composed of any media desired. The stacker creates little or no obstruction to access to the media supply in a roll feed and cutter assembly (not shown) which is positioned in the bottom of the machine. As shown in FIG. 1, the front of machine housing 8 has a plurality of brackets 13, 14, 18, and 19 attached thereto in pairs at predetermined heights. Each bracket has a relieved area therein for use that will be described hereinafter. An inverted "window shade" or web 20 is unrolled to the point of brackets 18 and 19 and has a web support bar 21 positioned within the relieved area of the brackets. The web is wound upon a roller 22 which is supported by brackets 23 connected to housing 8 and forms a stacking device for copy sheets 12 exiting portion 11 of housing 7. Roller assembly 26 includes web 20, web support member 21, roller 22 and a spring (not shown), which keeps the web in tension so that when web support member 21 is removed from brackets 18 and 19, the web will have a pull towards roller
22. An angled iron 24 forms a base copy sheet support for the copy sheets exiting the machine. The relieved areas in brackets 13, 14, 18 and 91 are located such that the resting of web support shaft 21 therein will cause the web to take an inverted triangular appearance, i.e., the web is angled slightly away from the front of the machine with the apex of the triangle being toward the bottom of housing 7. The length of the copy sheets desire...
