Abstract

In a conventional scanner, the scanner has an 11" by 17" platen wherein a similar size platen cover resides thereover. Typically, a scanner has a 1/8" high registration edge along the 11" side of the platen; however, the typical scanner has no registration edge on the 17" side of the platen. the lack of a registration edge on the 17" side of the platen causes problems when scanning books.

REMOVABLE HIGH REGISTRATION EDGE FOR BOOK SCANNING (Cont'd)

In a conventional scanner, the scanner has an 11" by 17" platen wherein a similar size platen cover resides thereover. Typically, a scanner has a 1/8" high registration edge along the 11" side of the platen; however, the typical scanner has no registration edge on the 17" side of the platen. the lack of a registration edge on the 17" side of the platen causes problems when scanning books.

Books are scanned by centering the binding on the platen and placing the top of the book at the back edge of the glass, the 17" inch side. On a typical scanner, the user interface allows the operator to scan either the left page, the right page, or both pages. The operator may also select edge trim size and gutter fill sizes.

Since there is no back registration edge, it is difficult to align the top of the book with the back of the platen glass, prevent skew, and center the binding from left to right.

One solution to this situation would be to provide a low 1/8" high registration edge along the back side of the platen glass. Another solution, which would be more useful, is to utilize a 1" high registration edge along the back edge of the platen glass to resolve the problems associated with scanning books. However, such a permanent high registration edge would prevent the platen cover from closing, and a permanent low registration edge would obstruct any document handler feed belts or drives that would be associated with the platen cover.

A third solution is illustrated in Figures 1 and 2. This system has a removable high registration device with no moving parts that simply drops into place. As shown in Fig...
