Abstract
An image reading apparatus includes an image reading portion that moves in a predetermined direction and has an image reading sensor that reads an image on a sheet. A sheet feeder feeds the sheet. A first transparent member has a reference surface that supports the sheet thereon, and a second transparent member contacts the sheet fed by the sheet feeder. The image reading portion moves along a lower surface of the second transparent member, and the second transparent member is positioned to overlap a portion of the first transparent member as viewed from a direction perpendicular to the reference surface. The image reading portion moves along a lower surface of the first transparent member and moves along a lower surface of the second transparent member.
Claims12
An image reading apparatus comprising:
- an image reading portion configured to move in a predetermined direction, the image reading portion comprising an image reading sensor configured to read an image on a sheet;
- a sheet feeder configured to feed the sheet;
- a first transparent member having a reference surface configured to support the sheet thereon;
- and
- a second transparent member configured to contact the sheet fed by the sheet feeder, the image reading portion moving along a lower surface of the second transparent member, wherein the second transparent member is positioned such that a portion of the second transparent member overlaps a portion of the first transparent member as viewed from a direction perpendicular to the reference surface, and such that the image reading portion reads the image on the sheet at a first position through the first transparent member, not through the second transparent member;
- and reads the image on the sheet at a second position through the second transparent member, not through the first transparent member,
- wherein the image reading portion is configured to move along a lower surface of the first transparent member and to move along a lower surface of the second transparent member.
An image reading apparatus comprising:
- an image reading portion configured to move in a predetermined direction, the image reading portion comprising an image reading sensor configured to read an image on a sheet;
- a sheet feeder configured to feed the sheet;
- a first transparent member having a reference surface configured to support the sheet thereon;
- and
- a second transparent member configured to contact the sheet fed by the sheet feeder, the image reading portion moving along a lower surface of the second transparent member, wherein the second transparent member is positioned such that a portion of the second transparent member overlaps a portion of the first transparent member as viewed from a direction perpendicular to the reference surface,
- wherein the image reading portion is configured to move along a lower surface of the first transparent member and to move along a lower surface of the second transparent member, and
- wherein the image reading portion is configured to slide along and contact the lower surface of the first transparent member and the lower surface of the second transparent member.
An image reading apparatus comprising:
- an image reading portion configured to move in a predetermined direction, the image reading portion comprising an image reading sensor configured to read an image on a sheet;
- a sheet feeder configured to feed the sheet;
- a first transparent member having a reference surface configured to support the sheet thereon;
- a second transparent member configured to contact the sheet fed by the sheet feeder, the image reading portion moving along a lower surface of the second transparent member, wherein the second transparent member is positioned such that a portion of the second transparent member overlaps a portion of the first transparent member as viewed from a direction perpendicular to the reference surface,
- wherein the image reading portion is configured to move along a lower surface of the first transparent member and to move along a lower surface of the second transparent member;
- and
- a connecting member configured to connect the first transparent member to the second transparent member, wherein the image reading portion is configured to selectively move between the lower surface of the first transparent member and the lower surface of the second transparent member via the connecting member.
