  • Patent number: 6107558
    Abstract: 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.
