US Patent 7918393 Leafing mechanism

A machine and methods for automatically opening a closed book, for example a passport, to a desired page for subsequent processing on the page. The book is inserted into the machine in a closed configuration. The machine then opens the book to the appropriate page for subsequent processing either in the machine or in a separate processing machine. A pin is inserted between two adjacent sheets of the book to define a first book portion and a second book portion, and the pin is used to assist in moving the first book portion away from the second book portion to expose the desired page for subsequent processing.
