Abstract

Disclosed is a device which enables photocopiers to print single sheets such that the printed material exits the copier facing down, instead of facing up. Modern copiers do not have an option to print single sheets facing down. This device could potentially dramatically improve productivity as described below. When photocopying multiple pages of a book, modern copiers make it necessary to sort the output by hand in order to have the pages ordered properly. For example: If photocopying page 1 to page 100 of a book, when done, the stack of output pages would have page 100 on the top of the stack and page 1 at the bottom of the stack. Then someone has to laboriously hand reshuffle the 100 pages so that they are again in order, i.e. page 1 on top and page 100 at bottom. This extra labor is caused by the fact the copier always prints the text and graphics on the side of a sheet that is facing up. The above described problem can be resolved with a button on the copier that lets the user select how to order the sheets when they exit from the copier, i.e. whether the text and graphics are on the facing-up side of the sheet, or on the facing-down side of the sheet. Consider the example again: If we are photocopying page 1 to 100 of a book, by selecting the "Copying on Facing-Down" option of the copier, page 100 would still be on the top of the stack and page 1 would still be at the bottom of the stack. However, because these pages exit facing down, all the user has to do is to turn the stack over will have page 1 on the top and page 100 at the bottom. No longer does the person needs to reshuffle the stack laboriously. This implementation could save thousands of hours of unproductive work by secretaries or anyone else who uses a copier to copy single sheets, such as a book, research papers, or other loose material. Other solutions include manually reshuffling the output (time consuming, laborious, boring, error-prone) or photocopying from the last page to the first page (confusing and error-prone due to the fact that it is not normal for people to flip pages backwards). The following diagram, Figure 1, illustrates a device which, when activated, assures that pages exit the copier face down. The text and graphics are printed onto paper in the copier normally. A series of rollers and a page-edge detector then implement the functionality of the invention. A printed page is rolled to a facing down position. When the page is completely face-down, the edge detector enables the rollers to roll in the opposite direction and eject the page face down. The edge detector detects when a complete page has rolled to a position such that it can be ejected facing down. In this way, the same exit slot is used for pages facing up or down, but when the facing-down device is activated, the pages exit facing-down.
