Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 164 words
A recording apparatus for recording on a recording sheet, said apparatus comprising: recording means for recording on the recording sheet; conveying means for conveying the recording sheet; a sheet guide member for guiding the recording sheet, said guide member being movable between a first position for guiding said recording sheet to a position for recording by said recording means and a second position, retracted from the first position; moving means for moving said guide member to either the first position or the second position; pinching means for pinching the recording sheet provided subsequent to said recording means with respect to a conveying direction of said recording sheet; and control means for controlling said moving means so that said guide member is positioned at the first position when a leading end of the recording sheet conveyed by said conveying means passes through the recording position and said guide member is positioned at the second position when the recording sheet is pinched by said pinching means.
Claim 2
Dependent Claim 164 words
A recording apparatus for recording on a recording sheet, said apparatus comprising: recording means for recording on the recording sheet; conveying means for conveying the recording sheet; a sheet guide member for guiding the recording sheet, said guide member being movable between a first position for guiding said recording sheet to a position for recording by said recording means and a second position, retracted from the first position; moving means for moving said guide member to either the first position or the second position; pinching means for pinching the recording sheet provided subsequent to said recording means with respect to a conveying direction of said recording sheet; and control means for controlling said moving means so that said guide member is positioned at the first position when a leading end of the recording sheet conveyed by said conveying means passes through the recording position and said guide member is positioned at the second position when the recording sheet is pinched by said pinching means.
Claim 3
Dependent Claim 23 words
A recording apparatus according to claim 1, wherein said pinching means comprises a platen roller and a pinch roller contacting said platen roller.
Claim 4
Dependent Claim 21 words
A recording apparatus according to claim 1, wherein said sheet guide member is movable along the periphery of a platen roller.
Claim 5
Dependent Claim 33 words
A recording apparatus according to claim 1, wherein said recording means is reciprocally movable along a conveyance path of the recording sheet when said sheet guide member is moved to the second position.
Claim 6
Dependent Claim 194 words
An ink jet recording apparatus for recording on a recording sheet by discharging ink, said apparatus comprising: an ink jet recording head for recording on the recording sheet, said head having a plurality of discharge ports for discharging ink therethrough; ink storing means for storing ink therein; conveying means for conveying the recording sheet; a sheet guide member for guiding the recording sheet, said guide member being movable between a first position for guiding said recording sheet to a position for recording by said ink jet recording head and a second position, retracted from the first position; moving means for moving said member to either the first position or the second position; pinching means for pinching the recording sheet provided subsequent to said ink jet recording head with respect to a conveying direction of said recording sheet; and control means for controlling said moving means so that said guide member is positioned at the first position when a leading end of the recording sheet conveyed by said conveying means passes through the recording position and said guide member is positioned at the second position when the recording sheet is pinched by said pinching means.
Claim 7
Dependent Claim 194 words
An ink jet recording apparatus for recording on a recording sheet by discharging ink, said apparatus comprising: an ink jet recording head for recording on the recording sheet, said head having a plurality of discharge ports for discharging ink therethrough; ink storing means for storing ink therein; conveying means for conveying the recording sheet; a sheet guide member for guiding the recording sheet, said guide member being movable between a first position for guiding said recording sheet to a position for recording by said ink jet recording head and a second position, retracted from the first position; moving means for moving said member to either the first position or the second position; pinching means for pinching the recording sheet provided subsequent to said ink jet recording head with respect to a conveying direction of said recording sheet; and control means for controlling said moving means so that said guide member is positioned at the first position when a leading end of the recording sheet conveyed by said conveying means passes through the recording position and said guide member is positioned at the second position when the recording sheet is pinched by said pinching means.
Claim 8
Dependent Claim 25 words
An ink jet recording apparatus according to claim 5, wherein said pinching means comprises a platen roller and a pinch roller contacting said platen roller.
Claim 9
Dependent Claim 23 words
An ink jet recording apparatus according to claim 5, wherein said sheet guide member is movable along the periphery of a platen roller.
Claim 10
