Abstract: Index tab holders are movably mounted on top portions of file folders or data separation sheets to locate the tab holders in selected lateral locations without removing the tab holders from the file folders. Linear rails associated with the top portions of the file folders cooperate with ribs on the tab holders to mount and laterally guide the tab holders on the file folders.

Abstract: An improved reading assistance device is provided for use within the video display terminal of a word processing system. The reading device subtends the video display terminal, receives paper with written subject matter, and displays selected portions of the paper to a user. It includes a housing with an inlet for receiving the paper, a display screen and light source for displaying the paper, a drive for moving the paper through the housing, and an outlet through which the device discharges the paper.

Abstract: A copy holder adapted to foster the efficient comparison of two sets of data, one of which is visible on a display associated with a computer, and the other being visible on a sheet of flexible material, e.g., a sheet of paper. The comparison is fostered by reducing the necessary eye travel as an operator switches his attention back and forth between the data on the flexible sheet and the data on the display. A structural housing having a thin profile supports the display device in front of a computer operator, such that an operator may still see the data that appears on the display screen. The housing has a frontal opening through which the sheet of flexible material may be manipulated by the operator; and it has a rear opening through which a surplus quantity of the flexible sheet may be pushed.

Abstract: A scrolling display device for fan-folded printout paper has a housing with two upstanding sides, an internal paper shelf overlying a paper storage bin, a slanting easel display plane panel pivotally mounted at the forward edge of the shelf with idler rollers along its upper edge and idler pinch rolls supported by its rear face; a capstan roller driven by a variable speed reversible drive engages the idler pinch rolls to advance the upfolded sheet drawn from the storage bin up and over the panel to descend behind the panel for re-fan-folded storage on the shelf.

Abstract: Page turner apparatus that includes a book support having a transverse ledge and a top flange, a slide plate on the support for transverse movement, the slide plate having a plurality of parallel slots for the pages to be turned extended therethrough, and operable mechanism for mounting the slide plate and selectively moving the slide plate to turn a page. The operable mechanism of each of the first and third embodiments includes a toothed rack slidably mounted on a slide rod and attached to the slide plate, and a foot pedal operated cable for selectively moving the rack in a page turning direction. In the second embodiment the operable mechanism includes a motor for driving a rod having a threaded portion cooperating with the threaded portion of a slide plate mounting block for transversely moving said block.
