Abstract
Abstract An electrostatic copying machine wherein the selector wheel is rotatable to a number of different positions to thereby select the number of copies to be made from an original and wherein the switch which starts the copying machine is actuated in response to depression of a knob which further serves to rotate the selector wheel by a step if the selector wheel is not rotated by hand. The knob can move a pawl which rotates a ratchet wheel stepwise, and the ratchet wheel can rotate the selector wheel through a pin-and-slot coupling which allows the ratchet wheel to rotate by a step relative to the selector wheel or vice versa. This insures that the selector wheel is not rotated in response to a first depression of the knob but is rotated in response to each subsequent depression of the knob. The selector wheel is reset to a starting position in a stepwise fashion by a second ratchet and pawl assembly which is actuated by a pneumatic cylinder in response to completion of successive copies.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
150 words
In an electrostatic copying machine, a combination comprising first and second control means respectively operable to start and terminate the making of copies from originals; selector means movable from a starting position to a plurality of second positions in each of which the machine is set to make a different number of copies from a given original; first indexing means for moving said selector means to a selected second position; second indexing means for moving said selector means stepwise to a selected second position, including actuating means for operating said first control means in response to each stepwise movement of said selector means under the action of said second indexing means; means for resetting said selector means stepwise toward said starting position in response to the making of copies; and means for operating said second control means in response to movement of said selector means back to said starting position.
Claim 2
Dependent Claim
150 words
In an electrostatic copying machine, a combination comprising first and second control means respectively operable to start and terminate the making of copies from originals; selector means movable from a starting position to a plurality of second positions in each of which the machine is set to make a different number of copies from a given original; first indexing means for moving said selector means to a selected second position; second indexing means for moving said selector means stepwise to a selected second position, including actuating means for operating said first control means in response to each stepwise movement of said selector means under the action of said second indexing means; means for resetting said selector means stepwise toward said starting position in response to the making of copies; and means for operating said second control means in response to movement of said selector means back to said starting position.
