Abstract
A first sheet passing path from an automatic sheet supplying section to a recording section and a second sheet passing path leading to an automatic reversing section from the recording section and leading to the recording section from the automatic reversing section share a part of them with each other, and the shared sheet passing path is provided with a guide member movable from a first position for the first sheet passing path to a second position for the second sheet passing path in synchronism with separation of a pinch roller from a sheet feeding roller.
Claims12
A both-side recording apparatus constructed so that a first sheet passing path for guiding a recording medium conveyed from an automatic sheet supplying section, and a second sheet passing path for guiding the recording medium conveyed to an automatic reversing section and conveyed from the automatic reversing section share a part of the first sheet passing path and the second sheet passing path with each other,
- wherein a guide member is said shared part of the sheet passing paths and is capable of taking a first position for the first sheet passing path and a second position for the second sheet passing path wherein the guide member guides the recording medium guided by the first sheet passing path or the second sheet passing path to a nip of the sheet feeding roller for conveying the recording medium and the pinch roller for pressing the recording medium to the sheet feeding roller,
- wherein the first sheet passing path is placed above the second sheet passing path,
- wherein said pinch roller contacts said conveying roller at a position of said conveying roller offset towards the recording section,
- wherein the first position is higher than the second position, and
- wherein said guide member located in the first position guides said recording medium to said nip from the position higher than the nip of said conveying roller and said pinch roller.
A both-side recording apparatus for performing recording onto a recording medium in a recording section, comprising:
- feeding means for feeding the recording medium;
- a conveying roller for conveying the recording medium to said recording section;
- a pinch roller for nipping the recording medium in cooperation with said conveying roller;
- a reversing section for reversing a front and a back of the recording medium conveyed in an opposite direction from the recording section by said conveying roller;
- and
- a guide member capable of moving to a first position and a second position, located in the first position to guide the recording medium conveyed from said feeding means or said reversing section to a nip of said conveying roller and said pinch roller, and located in the second position to guide the recording medium conveyed in the opposite direction from the recording section by said conveying roller to said reversing section,
- wherein a tip end of the recording medium fed from said feeding means or said reversing section abuts to the nip of said conveying roller and said pinch roller and is subjected to registration, and thereafter, is conveyed to said recording section by said conveying roller,
- wherein a first conveying path for guiding the recording medium to said conveying roller from said feeding means is placed above a second conveying path for guiding the recording medium to said reversing section from said conveying roller,
- wherein said pinch roller contacts said conveying roller at a position of said conveying roller offset towards the recording section,
- wherein the first position is higher than the second position, and
- wherein when said guide member located in the first position guides said recording medium to said nip from a position higher than the nip of said conveying roller and said pinch roller.
A both-side recording apparatus for performing recording onto a recording medium in a recording section, comprising:
- feeding means for feeding the recording medium;
- a conveying roller for conveying the recording medium to said recording section;
- a pinch roller for nipping the recording medium in cooperation with said conveying roller;
- a reversing section for reversing a front and a back of the recording medium conveyed in an opposite direction from the recording section by said conveying roller;
- and
- a guide member capable of moving to a first position and a second position, located in the first position to guide the recording medium conveyed from said feeding means or said reversing section to a nip of said conveying roller and said pinch roller, and located in the second position to guide the recording medium conveyed in the opposite direction from the recording section by said conveying roller to said reversing section,
- wherein a tip end of the recording medium fed from said feeding means or said reversing section abuts to the nip of said conveying roller and said pinch roller and is subjected to registration, and thereafter, is conveyed to said recording section by said conveying roller,
- wherein when said guide member guides the recording medium fed from said reversing section to the nip of said conveying roller and said pinch roller, said guide member is located in the first position when the recording medium is thin, and said guide member is located in the second position when the recording medium is thick,
- wherein a first conveying path from guiding the recording medium to said conveying roller from said feeding means is disposed above a second conveying path for guiding the recording medium to said reversing section from said conveying roller,
- wherein said pinch roller contacts said conveying roller at a position of said conveying roller offset towards the recording section,
- wherein the first position is higher than the second position, and
- wherein said guide member located in the first position guides said recording medium to said nip from a higher position than the nip of said conveying roller and said pinch roller.
