Abstract

A book copying apparatus is disclosed that makes the copying of bound volumes simpler and easier than is presently available on copiers with horizontal platens where books have to be pressed against the platens and thereby subjecting the pages of the books to possible damage. Moreover, if the pressure applied is not uniform and/or the position of the books is disturbed, unusable copies usually result. Productivity is also hampered by this cumbersome method of bound volume copying.

A book copying apparatus is disclosed that makes the copying of bound volumes simpler and easier than is presently available on copiers with horizontal platens where books have to be pressed against the platens and thereby subjecting the pages of the books to possible damage. Moreover, if the pressure applied is not uniform and/or the position of the books is disturbed, unusable copies usually result. Productivity is also hampered by this cumbersome method of bound volume copying.

A solution to the problems encountered when copying from books on horizontal platen machines is disclosed in the figure where a partial schematic is shown of a copier having two platens H and V that form a corner of the copier. The exposure lamp L is positioned adjacent the inside surface of the corner formed by horizontal platen H and vertical platen V. A book 2 to be copied is placed over the corner formed by the two platens and exposed by lamp L moving first in the A-8 direction and then in the C-D direction. As a result, desired copies are made with a minimum of effort and disturbance to the sheets in the book.

Other methods of copying could be employed with the disclosed apparatus. For
example, two pages of the book 2 could be copied onto one sheet. Also, platens V
and H could be used for positioning two documents and scanning them for either simplex or duple...
