Abstract
Abstract A draft-transfer format for an electronic photocopying machine that reciprocates a draft-setter holding a draft sheet at a designated position and projects a picture of the draft document onto a photosensitive member. A conveying mechanism is installed above the draft-setter which conveys the inserted draft sheet to the predetermined position on the draft-setter. A drive force transmission mechanism is provided for transmitting a drive force to the conveying mechanism. A first drive mechanism is provided inside the photocopying machine which transmits the drive force to the drive force transmission mechanism during copying and a second drive mechanism is provided for transmitting the drive force to the drive force transmission mechanism during the return movement of the draft-setter after completing the draft-scanning operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
A document transfer system for an electronic photocopying machine incorporating a reciprocating draft-conveying device that reciprocates with a draft-setter supporting a draft sheet at a designated position and which photocopying machine projects a picture of the draft document onto a photosensitive member during draft-scanning and copying comprising: a conveying means positioned above said draft-setter for conveying said inserted draft sheet to a predetermined position on said draft-setter; a drive force transmission means for transmitting a drive force to said conveying means; a first drive means provided in said photocopying machine for transmitting said drive force to said drive force transmission means during positioning of said draft sheet on said draft-setter; and a second drive means for transmitting said drive force to said drive force transmission means during return movement of said draft-setter following completion of said draft-scanning and copying operation.
Claim 2
Dependent Claim
140 words
A document transfer system for an electronic photocopying machine incorporating a reciprocating draft-conveying device that reciprocates with a draft-setter supporting a draft sheet at a designated position and which photocopying machine projects a picture of the draft document onto a photosensitive member during draft-scanning and copying comprising: a conveying means positioned above said draft-setter for conveying said inserted draft sheet to a predetermined position on said draft-setter; a drive force transmission means for transmitting a drive force to said conveying means; a first drive means provided in said photocopying machine for transmitting said drive force to said drive force transmission means during positioning of said draft sheet on said draft-setter; and a second drive means for transmitting said drive force to said drive force transmission means during return movement of said draft-setter following completion of said draft-scanning and copying operation.
Claim 3
Dependent Claim
66 words
The document-transfer system of claim 1, including: a first sensor switch for detecting the presence of said draft sheet to be introduced onto said draft-setter; and a second sensor switch for detecting when said draft sheet has reached said predetermined position on said draft-setter; said first drive means driving said drive force transmission means during the period wherein said draft sheet is positioned on said draft-setter.
Claim 4
Dependent Claim
19 words
The document transfer system of claim 1, wherein said second drive means comprises a solenoid controlled spring biased bar.
