Abstract

The copying of pages in thick books is facilitated by using two parallel slides to mount the platen cover on the optics frame, so that the cover is liftable bodily off the copier when copying from books. After the book has been placed in position on the platen, the cover is replaced so that its weight presses the pages to be copied against the platen. The slides ensure that the cover remains substantially parallel to the platen so as not to apply any localised forces to the platen which might tend to crack it.

LIFTING PLATEN COVER (Cont'd)

The copying of pages in thick books is facilitated by using two parallel slides to mount the platen cover on the optics frame, so that the cover is liftable bodily off the copier when copying from books. After the book has been placed in position on the platen, the cover is replaced so that its weight presses the pages to be copied against the platen. The slides ensure that the cover remains substantially parallel to the platen so as not to apply any localised forces to the platen which might tend to crack it.

As shown in Fig. 1 of the drawing, the platen cover 2 is connected through a normal hinge 4 to a cover support 6 intended to remain parallel to the platen 8 at all times. Extendin perpendicularly to support 6 is the inner member 10 of

recesses in the optics frame 16. Fig. 2 shows the arrangement of the slide 12 in more detail.

The outer member 14 is held in place in frame 16 largely by gravity. The inner member 10 is mounted in the outer member in a mai...
