ABSTRACT:
An improved selector mechanism is described for use in a sheet feeder that has a plurality of bins and a feedout roller shaft associated with each bin, for selecting which of the feedout rollers to rotate, the selection being made by determining the angles at which rotation of a drive member is reversed. Each selector includes a cam assembly connected to the feedout roller shaft by a one-way clutch, and a driven driver which is freely rotatable on the shaft. The driver carries a pivotally mounted arm. The cam assembly has a deflector which moves the arm to a deflected position when the arm rotates in a nonfeed direction, and also carries an arm engager which engages the deflected arm when the driver reverses rotation after the arm is deflected, so the driver rotates the cam and, therefore, the feedout roller shaft in a feed direction. The cam also carries an undeflector which moves the arm back to its undeflected position if the driver rotates too far beyond the point of its encounter with the deflector. The cam includes a groove that receives a follower on the driver, to position the cam assembly and driver in known angular positions before reversal of the driver.
