Abstract
Abstract For achieving a high positional accuracy of the paper with respect to a printing head (7) and a stable paper feeding over a long period in a printer, a paper feeding apparatus for a printer comprises a platen (5), a paper feeding tractor (11) for feeding fan-fold paper (13), arranged at the upstream side of said platen (5) with respect to the paper feeding direction (d), a power mechanism (6, 14 - 18) for driving said platen (5) and said paper feeding tractor (11), a roller (1) located at the downstream side of said palten and coupled to said power mechanism to rotate with the same or a higher circumferential speed than that of the platen (5), and a pressing member (2, 20) for pressing the paper (13) which is fed out from the upper side of the platen (5) after printing, against said roller (1).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A paper feeding apparatus for a printer, comprising: a platen (5), a paper feeding tractor (11) for feeding fan-fold paper (13), arranged at the upstream side of said platen (5) with respect to the paper feeding direction (d), a power mechanism (6, 14 - 18) for driving said platen (5) and said paper feeding tractor (11), a roller (1) located at the downstream side of said palten and coupled to said power mechanism to rotate with the same or a higher circumferential speed than that of the platen (5), and a pressing member (2, 20) for pressing the paper (13) which is fed out from the upper side of the platen (5) after printing, against said roller (1).
Claim 2
Dependent Claim
118 words
A paper feeding apparatus for a printer, comprising: a platen (5), a paper feeding tractor (11) for feeding fan-fold paper (13), arranged at the upstream side of said platen (5) with respect to the paper feeding direction (d), a power mechanism (6, 14 - 18) for driving said platen (5) and said paper feeding tractor (11), a roller (1) located at the downstream side of said palten and coupled to said power mechanism to rotate with the same or a higher circumferential speed than that of the platen (5), and a pressing member (2, 20) for pressing the paper (13) which is fed out from the upper side of the platen (5) after printing, against said roller (1).
Claim 3
Dependent Claim
44 words
An apparatus according to claim 1, wherein said pressing member (2) comprises two pressing member portions arranged at both sides of said roller (1) in the axial direction thereof, overlapping said roller (1) in a direction perpendicular to the axis of the roller (1).
Claim 4
Dependent Claim
16 words
An apparaus according to claim 2, wherein each pressing member portion (2) comprises an auxiliary roller.
Claim 5
Dependent Claim
25 words
An apparatus according to claim 2, wherein said pressing member comprises a paper guide cover (20) having rib portions (20b) forming said pressing member portions.
Claim 6
Dependent Claim
167 words
A paper feeding apparatus for a printer, comprising: a platen (5) supported rotatably to feed paper (13), a paper presser means (12), a paper presser lever (24) for supporting the paper presser means (12), which is rotatable between a position in which the paper presser means (12) presses the paper (13) against the platen (5) and a position in which the paper (13) is released from the paper presser means (12), a pressing member (32) for supplying pressing force to the paper presser lever in said paper-pressing position, and a driving means (46) for supplying a driving force to rotate said paper presser lever (24), wherein a control apparatus for controlling energization of said driving means (46) is provided, said control apparatus performing one energization or a plurality of successive energizations of said driving means (46) for moving said paper presser lever (24) from said released position to said pressing position and/or for moving said paper presser lever (24) from said pressing position to said released position.
Claim 7
Dependent Claim
167 words
A paper feeding apparatus for a printer, comprising: a platen (5) supported rotatably to feed paper (13), a paper presser means (12), a paper presser lever (24) for supporting the paper presser means (12), which is rotatable between a position in which the paper presser means (12) presses the paper (13) against the platen (5) and a position in which the paper (13) is released from the paper presser means (12), a pressing member (32) for supplying pressing force to the paper presser lever in said paper-pressing position, and a driving means (46) for supplying a driving force to rotate said paper presser lever (24), wherein a control apparatus for controlling energization of said driving means (46) is provided, said control apparatus performing one energization or a plurality of successive energizations of said driving means (46) for moving said paper presser lever (24) from said released position to said pressing position and/or for moving said paper presser lever (24) from said pressing position to said released position.
Claim 8
Dependent Claim
84 words
