A rotatable image-mounting drum for use in a scanner or plotter. The drum has an end for permitting the releasable attachment of the drum to the scanner's or plotter's supporting and turning means. The drum's image-mounting surface and the drum's attachment end are preferably made of the same material, preferably acrylic. The attachment end of the drum includes a disk at the end of the drum, which has an opening or openings passing from its outer face to its inner face. The other end of the drum preferably is not attached directly to the rest of the scanner. The plotter's or scanner's mechanism for releasably attaching the rotatable drum includes a drum mount rotatable by a motor. A clasp stem, passing through a drum-mount opening, has a clasp finger rigidly attached thereto. A cam surface, having a varying elevation, can be rotated so as to push the cam stem through the drum-mount opening. A spring urges the stem against the cam surface. As the cam surface is rotated with respect to the drum mount, the distance between the finger and the drum mount's exterior side varies. The finger can pass through the opening in the attachment end of the drum, and the drum may be clasped between the finger and the drum mount's exterior side.

An awning roller with a two-position, bi-directional locking mechanism. In the first position, rotation of the roller is permitted in a clockwise direction, but prevented in a counterclockwise direction. The second position allows rotation in a counterclockwise direction, but not in a clockwise direction. The roller comprises an outwardly facing pinion gear at one end of the roller. A pawl is rotatably mounted adjacent the pinion gear to interact with the teeth so as to control the direction of rotation of the roller as described above. The pawl can be repositioned relative to the ratchet disc to change the locking mechanism from its first position to its second position and back again.

Bidirectional awning roller

A flexible sheet transport system comprising a primary mechanism for feeding the flexible sheet at a predetermined velocity in either a forward or a reverse direction, a tension roller assembly disposed in the path of the flexible sheet so as to be frictionally engaged thereby, an auxiliary drive mechanism for applying tension to the flexible sheet, a coupling assembly connected between the tension roller assembly and the auxiliary drive mechanism and driven thereby in a given sense tending to rotate the tension roller in a direction to move the flexible sheet in the reverse direction. Included in the coupling assembly is a slip coupling that slips in response to application of a given torque and a unidirectional coupling that prevents movement of the coupling assembly in a sense opposite to the given sense.
