Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
198 words
A document handling apparatus including document feed means for feeding documents one at a time past a registration means into a processing area, document transport means positioned over said processing area and adapted to contact a portion of each of said documents for controlling its movement, said transport means being adapted to move said document in a first direction into said processing area, to reverse said document to move it in a second direction to register said document in cooperation with said registration means and, after processing, to move the document again in said first direction to remove it from said processing area; baffle means overlying said processing area adjacent said registration means; and, lift means for moving said baffle means into and out of engagement with said registration means, said baffle means being arranged such that in use of the apparatus, it is moved out of engagement with said registration means during movement of a document in said first direction into said processing area, and is moved into engagement with the registration means during movement of a document in said second direction to prevent movement of said document past said registration means during registration of said document.
Claim 2
Dependent Claim
198 words
A document handling apparatus including document feed means for feeding documents one at a time past a registration means into a processing area, document transport means positioned over said processing area and adapted to contact a portion of each of said documents for controlling its movement, said transport means being adapted to move said document in a first direction into said processing area, to reverse said document to move it in a second direction to register said document in cooperation with said registration means and, after processing, to move the document again in said first direction to remove it from said processing area; baffle means overlying said processing area adjacent said registration means; and, lift means for moving said baffle means into and out of engagement with said registration means, said baffle means being arranged such that in use of the apparatus, it is moved out of engagement with said registration means during movement of a document in said first direction into said processing area, and is moved into engagement with the registration means during movement of a document in said second direction to prevent movement of said document past said registration means during registration of said document.
