ABSTRACT:
A storage and selectable display device for sheet media includes an enclosure having a slot. A rotatable spool is secured within the enclosure. A leader assembly attaches the sheets to the spool so that the free edges of the sheets are circumferentially disposed about the spool when rolled up. Individual leaders are attached to a master leader and charts are attached to the individual leaders. An actuator connected through a clutch rotates the spool to wind the sheets. Opposite rotation is prevented by the clutch. Belts frictionally engage a portion of the outermost surface of the spool and rolled sheets. Shafts are provided to hold the belts in position. The belt drive shaft is connected to the actuator by gearing and a clutch. The clutch actuates in the unwind direction, but not in the opposite direction. A flexible, resilient, transparent window has one edge which resiliently engages the rolled charts.
An alternative ejection system includes a lay shaft and frictionally engaged idler roller. The lay shaft is rotated by connection to the actuator and through a clutch which prevents rotation in the wind direction and causes rotation in the opposite direction.
Another embodiment of the enclosure has a planar upper surface forming a plotting surface; a slot along one side of such surface; a translating plotting arm; a cursor support on the plotting arm and a cursor pivotally connected to the support for rotation about an axis normal to the plotting surface.
