Abstract

Abstract A pair of rollers defining a nip transporting sheets in a first direction for a first mode of operation. A clutch operated drive belt rotates the frame supporting the rolls about an axis through the nip to invert the sheets for a second mode of operation. At the same time a releasable latch serves to release and then stop the frame after rotation through an angle of about 180* for the second mode of operation.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 171 words
In a reproducing system in which simplex and duplex copies are made in a processor and then distributed, an improved sheet handling apparatus comprising: a rotatable frame, first and second roll means supported by said rotatable frame defining a nip for receiving copy sheets from a processor, first drive means for continuously driving said first roll means on its axis, second drive means for rotating said frame carrying said first and second roll means about an axis through said nip at substantially the same speed and in the same direction as that of said first roll means, and control means to actuate said second drive means in response to signals to rotate said frame carrying said roll means about an angle of 180* about an axis through said nip while said first drive means is continuously driving said first roll means such that there is no apparent movement of said roll means to effect the top of the sheets becoming the bottom and the trailing edge thereof becoming the leading edge.
Claim 2
Dependent Claim 171 words
In a reproducing system in which simplex and duplex copies are made in a processor and then distributed, an improved sheet handling apparatus comprising: a rotatable frame, first and second roll means supported by said rotatable frame defining a nip for receiving copy sheets from a processor, first drive means for continuously driving said first roll means on its axis, second drive means for rotating said frame carrying said first and second roll means about an axis through said nip at substantially the same speed and in the same direction as that of said first roll means, and control means to actuate said second drive means in response to signals to rotate said frame carrying said roll means about an angle of 180* about an axis through said nip while said first drive means is continuously driving said first roll means such that there is no apparent movement of said roll means to effect the top of the sheets becoming the bottom and the trailing edge thereof becoming the leading edge.
Claim 3
Dependent Claim 17 words
Apparatus according to claim 1 wherein said control means includes sheet sensing means for generating electrical signals.
Claim 4
Dependent Claim 17 words
Apparatus according to claim 2 wherein said signals actuate electrical clutch means drivingly connected to said frame.
Claim 5
Dependent Claim 23 words
Apparatus according to claim 3 wherein said electrical signals actuate a solenoid operated latch released momentarily out of the path of said frame.
