Patent number: 6107558Abstract: The notion of a reliable semi-automatic page-changer apparatus has heretofore been elusive to inventors, however with the event of a major new handling technique, a practical solution is herein introduced. Predicated upon the principle of establishing a modular standard for the viewed paper, facilitating either sheet-music for musicians or text-pages for speakers. This involves generally utilizing the US/81/2.times.11-inch format, or the european A4/29.7.times.21 cm format, whereby any pre-existing graphic-copy can be readily and economically transferred thereto via convenient photocopy machine process and via a special hangeer-hole device, overcoming the usual disfunctional predisposition toward inter-clinging of the stacked pages. Generally using a foot-operated sequencing-switch, the instant page is transferred via a novel spindle-conveyer to a holding-stack; enabling viewing of consecutive pages either at their originating elevated position or at their final landing position there below.Type: GrantFiled: February 17, 1999Date of Patent: August 22, 2000Inventor: William W.

Patent number: 4644675Abstract: A page turner device for an open book comprises a support for the book, and a power driven disc configured to rest on the top of the pages of such open book. When the power drive is energized, the disc will start to rotate while in contact with the open pages. The disc has a finger portion which protrudes outwardly from adjacent portions of the disc, and a page curler drive is used for creating a curl or arch in the center portions of an open page, so that when the finger rotates to the proper position, it will go into the recess under the curl, and as it continues to rotate, the finger will pull the page with it. When the disc comes to a rest position, the finger will have completely opened the subsequent page. At the rest position a cam operates a switch to disable the power drive until such time as the person reading again initiates a manual switch to commence the page turning sequence.Type: GrantFiled: February 11, 1985Date of Patent: February 24, 1987Assignee: Regents of the University of MinnesotaInventors: John G.
