Abstract
Abstract The present invention relates to a printer including a printing station (13, 14) and a multi-function document feeding system for feeding and guiding a document through the printing station. The feeding system comprises a friction roll document feeding means (24, 25, 26, 27), a pin wheel document feeding means (33, 34, 35) for feeding a document (D) of the continuous web type having uniformly spaced pin feed holes in its outer edges, and document guide means including a first set of document guide members (40, 42, 48) defining a first feed path for document travel through the printer and a second set of document guide members (44, 46, 42) defining a second feed path for document travel through the printer. A printer according to the invention is characterised in that the friction roll document feeding means (24, 25, 26, 27) is located upstream of the printing station (13, 14) in the direction of movement of a document through the friction roll feeding means and is capable of feeding of both individual cut form documents (C) and continuous web type documents (D). The first feed path (40, 42, 48) extends through the pin wheel document feeding means (33, 34, 35), through the friction roll document feeding means (24, 25, 26, 27) and through the printing station (13, 14) to provide a feed path for a continuous web type document (D), and the second feed path (44, 46, 42) extends through the friction roll feeding means (24, 25, 26, 27) and through the printing station (13, 14) to provide a feed path for individual cut form documents (C).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
251 words
A printer including a printing station (13, 14) and a multi-function document feeding system for feeding and guiding a document through said printing station, said feeding system comprising a friction roll document feeding means (24, 25, 26, 27), a pin wheel document feeding means (33, 34, 35) for feeding a document of the continuous web type having uniformly spaced pin feed holes in its outer edges, and document guide means including a first set of guide members (40, 42, 48) defining a first feed path for document travel through said printer and a second set of guide members (44, 42, 46) defining a second feed path for document travel through said printer characterised in that said friction roll document feeding means (24, 25, 26, 27) is located upstream of said printing station (13, 14) in the direction of movement of a document through said friction roll feeding means and is capable of feeding of both individual cut form documents (C) and continuous web type documents (D), said first feed path (40, 42, 48) extends through said pin wheel document feeding means (33, 34, 35), through said friction roll document feeding means (24, 25, 26, 27) and through said printing station (13, 14) to provide a feed path for a continuous web type document (D) and said second feed path (44, 42, 46) extends through said friction roll feeding means (24, 25, 26, 27) and through said printing station (13, 14) to provide a feed path for individual cut form documents (C).
Claim 2
Dependent Claim
251 words
A printer including a printing station (13, 14) and a multi-function document feeding system for feeding and guiding a document through said printing station, said feeding system comprising a friction roll document feeding means (24, 25, 26, 27), a pin wheel document feeding means (33, 34, 35) for feeding a document of the continuous web type having uniformly spaced pin feed holes in its outer edges, and document guide means including a first set of guide members (40, 42, 48) defining a first feed path for document travel through said printer and a second set of guide members (44, 42, 46) defining a second feed path for document travel through said printer characterised in that said friction roll document feeding means (24, 25, 26, 27) is located upstream of said printing station (13, 14) in the direction of movement of a document through said friction roll feeding means and is capable of feeding of both individual cut form documents (C) and continuous web type documents (D), said first feed path (40, 42, 48) extends through said pin wheel document feeding means (33, 34, 35), through said friction roll document feeding means (24, 25, 26, 27) and through said printing station (13, 14) to provide a feed path for a continuous web type document (D) and said second feed path (44, 42, 46) extends through said friction roll feeding means (24, 25, 26, 27) and through said printing station (13, 14) to provide a feed path for individual cut form documents (C).
Claim 3
Dependent Claim
185 words
A printer according to Claim 1 characterised in that said first feed path extends through said pin wheel document feeding means (33, 34, 35) after leaving said printing station (13, 14), and in that the length of the path of travel for a document (D) in said first feed path from the portion (40a) of the path upstream of said printing station which extends through said pin wheel document feeding means where a first set of pin feed holes (30) in said document (D) engage with the pins (34) of the pin wheels (33) of the feeding means and the portion (48) of said path downstream of said printing station which extends through said pin wheel document feeding means where a second set of pin feed holes (30) in said document (D) engage with the pins (34) of said pin wheels is slightly greater than the distance between the said two sets of pin feed holes so that a document (D) being fed by said pin wheel document feeding means along said first feed path is under tension as it passes through said printing station.
Claim 4
Dependent Claim
68 words
A printer according to Claim 1 or Claim 2 characterised in that said second feed path comprises guide members defining a first section (44, 42) extending from the rear of said printer to said friction roll document feeding means (24, 25, 26, 27) and a second section (44, 46, 42) extending from the front of said printer to said friction roll document feeding means (24, 25, 26, 27).
Claim 5
Dependent Claim

A printer according to ~Claim 3 characterised in that the first section of said second feed path comprises guide members (44, 42) which extend downwardly from the top of said printer and rearwardly of and beneath said pin wheel document feeding means (33, 34, 35) directly into said friction roll driving means (24, 25, 26, 27).
Claim 6
Dependent Claim

Claim 8
Dependent Claim
53 words
A printer according to Claim 6 characterised in that one (46) of said two guide members (44, 46) is located above the other guide member (44) and the rear portion of said upper guide member (46) comprises an extension (50) which extends through said friction roll document feeding means (24, 25, 26, 27).
