Abstract

It frequently is desirable to be able to copy a document onto a copy sheet other than the type of paper in the paper cassette without disturbing the paper cassette that is already in the machine. The figures illustrate an overlay tray that can be designed for this purpose. In Figure 1 a universal cassette 10 is illustrated which would hold a stack of sheets biased upwardly (by means not shown) into the feeding position with a rotatably mounted driven segmented feed wheel 14. An overlay which may also function as a cassette cover 12 can be designed to slide along the top of the cassette side walls. A5 shown in Figure I this is in the inactive position whereas in Figure 2 overlay tray 12 has been slid to the right into position directly below the feed wheels of the paper feeder. This will prevent the feed wheels from feeding paper from the paper cassette and an alternative piece of paper may be placed on the overlay tray and be fed. The portion of the overlay tray under the feed wheels may be designed to flex downward as the paper feeder feeds the sheet on the overlay tray forward. The overlay tray may be manually pushed to the right into locking engagement with latch 16 to fasten into the operating position as shown in Figure 2. The overlay tray may also be spring loaded to move out from under the feed wheels when not held in position by the latch during feedings. Accordingly as illustrated by the dotted line in Figure 2 when the latch 16 is removed the spring 18 biases the overlay tray to an inactive position. Since the overlay tray is designed to rest only on the top of the cassette it can be easily removed when changing or adding paper to the paper stack. This provides a relatively inexpensive, reliable and convenient capability of feeding an alternative copy sheet to an office copier.
