Abstract
Abstract The present invention includes a method of and means for ensuring the accurate registry of an original and copy sheet upon their introduction into a copying machine. The copy sheet is first fed to a starting position by drive means and at the starting position the copy sheet actuates a microswitch. Actuation of this first microswitch disengages the drive means for the copy sheet and engages drive means for an original sheet. The original sheet is driven to a ready position where its driving force is disengaged upon the actuation of a second microswitch at the ready position. After a short time delay, the second microswitch permits engagement of a third driving means completely separate from the first and second driving means associated with the copy and original, the third driving means feeding the original and copy sheet in strict super imposition to the receiving portion of the copy machine.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
Apparatus for feeding an original and a copy sheet simultaneously to a copy machine including: a. first means for feeding a copy sheet; b. second means for feeding an original; c. a first drive means connected to each said feeding means and selectively disengageable therefrom; d. a microswitch interposed in the line of feed and actuated by the passage of said copy sheet and control circuitry, responsive to actuation of said microswitch, automatically operable to disengage the drive means from said copy sheet feed means; e. a second microswitch interposed in the line of feed and actuated by the passage of said original and control circuitry responsive to actuation of said microswitch operable to disengage the drive means from said original feed means; f. second drive means operable to drive the first and second feed means in synchronism with a feed mechanism of a copy machine; and g. time delay means to momentarily delay operation of said second drive means after the disengagement of said first drive means from said original feed means.
Claim 2
Dependent Claim
173 words
Apparatus for feeding an original and a copy sheet simultaneously to a copy machine including: a. first means for feeding a copy sheet; b. second means for feeding an original; c. a first drive means connected to each said feeding means and selectively disengageable therefrom; d. a microswitch interposed in the line of feed and actuated by the passage of said copy sheet and control circuitry, responsive to actuation of said microswitch, automatically operable to disengage the drive means from said copy sheet feed means; e. a second microswitch interposed in the line of feed and actuated by the passage of said original and control circuitry responsive to actuation of said microswitch operable to disengage the drive means from said original feed means; f. second drive means operable to drive the first and second feed means in synchronism with a feed mechanism of a copy machine; and g. time delay means to momentarily delay operation of said second drive means after the disengagement of said first drive means from said original feed means.
Claim 3
Dependent Claim
19 words
The apparatus as defined in claim 1 wherein the first drive means includes an auxiliary constant speed drive motor.
Claim 4
Dependent Claim
48 words
The apparatus as defined in claim 1 wherein first and second brake means provide for the driving means of said original and copy sheet and said brakes are engaged respectively upon the disengagement of the first drive from the copy sheet feed means and the original feed means.
Claim 5
Dependent Claim
26 words
The apparatus as defined in claim 1 wherein the first and second microswitches are positioned an equal distance from the feed rollers of a copy machine.
Claim 6
Dependent Claim
24 words
The apparatus as defined in claim 1 wherein the second drive means is the driving means for the feed rolls of a copy machine.
Claim 7
Independent Claim
149 words
The method of feeding an original and a copy sheet simultaneously to a copying machine, the improvement comprising: passing the copy sheet to a ready station, introducing an original into the machine, passing the original to a predetermined start position, said ready station and said start position being equally spaced from a feed point of the copy machine, detecting the arrival of the original at the start position, braking the original for a predetermined period of time at the start position in response to the detection of the arrival of the original at the start position, and engaging a clutch to drive the original and the copy sheet in strict coincidence at a predetermined required copying speed to the feed point of the copying machine in response to the detection of the arrival of the original at the start position and after elapse of said predetermined period of time.
