Abstract
An apparatus in which a tubular member mounted on a shaft moves linearly in response to rotation of the shaft. A cam is mounted on the shaft and in engagement with bearings mounted on the interior surface of the tubular member. As the shaft rotates, the cam moves in unison therewith to move the tubular member linearly. The linear movement of the tubular member moves a portion of a photoconductive belt between an operative position, adjacent a developer unit, and an inoperative position, spaced from the developer unit.
Claims6
An apparatus for moving at least a portion of a belt between an inoperative position, spaced from a processing station, and an operative position, adjacent the processing unit, including:
- a tubular member in contact with the belt;
- a shaft disposed interiorly of said tubular member;
- and
- means, mounted on said shaft interiorly of said tubular member, for moving said tubular member linearly to move the belt between the operative position and the inoperative position, said moving means rotating in unison with said shaft and supporting said tubular member rotatably so that said moving means moves said tubular member linearly in response to rotation of said shaft;
- and
- means for rotating said shaft through a preselected angle.
An electrophotographic printing machine of the type in which a photoconductive belt having an electrostatic latent image recorded thereon moves between an inoperative position, spaced from a developer unit, and an operative position, adjacent the developer unit, including:
- a tubular member in contact with the photoconductive belt;
- a shaft disposed interiorly of said tubular member;
- and
- means, mounted on said shaft interiorly of said tubular member, for moving said tubular member linearly so as to move the photoconductive belt between the operative position and the inoperative position, said moving means rotating in unison with said shaft and supporting said tubular member rotatably so that said moving means moves said tubular member linearly in response to rotation of said shaft;
- and
- means for rotating said shaft through a preselected angle.
