Abstract
An image reading apparatus for reading image information from a sheet includes a cover unit, a sheet feeding member, a conveying guide, and a reading unit including a transparent member and a reading portion. The cover unit is rotatable between a closed position where the cover unit forms a sheet conveying passage in cooperation with the conveying guide and an open position where the sheet conveying passage is open. In a state in which the cover unit is positioned in the closed position, the transparent member is exposed to an outside of the image reading apparatus by rotation of the conveying guide and the reading unit.
Claims23
An image reading apparatus for reading image information from a sheet, comprising:
- a cover unit provided rotatably about a first rotational axis and including an upper surface of said image reading apparatus;
- a sheet conveying member configured to convey the sheet along a sheet conveying passage;
- a conveying guide provided rotatably about a second rotational axis different from the first rotational axis and configured to guide the sheet fed by said sheet conveying member;
- and
- a reading unit which includes a transparent member and a reading portion configured to read, through said transparent member, an image on the sheet fed by said sheet conveying member and which is provided rotatably about a third rotational axis different from the first rotational axis and the second rotational axis,
- wherein said cover unit is rotatable between a closed position where said cover unit forms the sheet conveying passage in cooperation with said conveying guide and an open position where the sheet conveying passage is open, and
- wherein in a state in which said cover unit is positioned in the open position, said transparent member is exposed to an outside of said image reading apparatus by rotation of said conveying guide and said reading unit.
An image forming apparatus comprising:
- an image reading apparatus configured to read image information from a sheet;
- and
- an image forming member configured to form an image on a recording material on the basis of the image information read by said image reading apparatus,
- wherein said image reading apparatus includes:
- a cover unit provided rotatably about a first rotational axis and including an upper surface of said image reading apparatus;
- a sheet conveying member configured to convey the sheet along a sheet conveying passage;
- a conveying guide provided rotatably about a second rotational axis different from the first rotational axis and configured to guide the sheet fed by said sheet conveying member;
- and
- a reading unit which includes a transparent member and a reading portion configured to read, through said transparent member, an image on the sheet fed by said sheet conveying member and which is provided rotatably about a third rotational axis different from the first rotational axis and the second rotational axis,
- wherein said cover unit is rotatable between a closed position where said cover unit forms the sheet conveying passage in cooperation with said conveying guide and an open position where the sheet conveying passage is open, and
- wherein in a state in which said cover unit is positioned in the open position, said transparent member is exposed to an outside of said image reading apparatus by rotation of said conveying guide and said reading unit.
An image reading apparatus for reading image information from a sheet, comprising:
- a sheet conveying member configured to convey the sheet along a sheet conveying passage;
- a reading unit which includes a transparent member and a reading portion configured to read, through said transparent member, an image on the sheet fed by said sheet conveying member and which is provided rotatably about a rotational axis between a first position where said transparent member opposes the sheet conveying passage and a second position where said transparent member is exposed,
- wherein in a state in which said reading unit is positioned in the first position, said transparent member faces downward in a vertical direction, and
- wherein in a state in which said reading unit is positioned in the second position, said transparent member faces upward in the vertical direction.
