Abstract
A document reading apparatus includes a housing including a bottom surface formed with a reading opening for reading a document, position detection sections disposed on the bottom surface while interposing the reading opening therebetween to detect a position of the document reading apparatus, and foot sections each having a contact surface being in contact with the document and a detection opening formed in a part of the contact surface, the detection opening facing the position detection section on the bottom surface.
Claims10
A document reading apparatus comprising:
- a housing including a bottom surface formed with a reading opening for reading a document;
- position detection sections disposed on the bottom surface while interposing the reading opening therebetween to detect a position of the document reading apparatus;
- and
- foot sections each having a contact surface being in contact with the document and a detection opening formed in a part of the contact surface, the detection opening facing the position detection section on the bottom surface.
A document reading apparatus comprising:
- a housing including a bottom surface having a reading opening for reading a document and a contact surface being in contact with the document;
- and
- position detection sections disposed on the bottom surface while interposing the reading opening therebetween to detect a position of the document reading apparatus,
- wherein the contact surface is formed to surround the position detection sections.
A document reading apparatus, comprising:
- a housing comprising a generally horizontal surface defining a reading opening, wherein the apparatus is configured to read a document through the reading opening;
- at least one position detector, configured to detect a position of the document reading apparatus relative to the document;
- and
- a protrusion, protruding in a perpendicular direction from the horizontal surface, and defining a window therein, wherein a distal end of the protrusion is a farthest point of the apparatus in the perpendicular direction, such that the distal end of the protrusion always contacts the document when the apparatus is in use;
- wherein the position detector is disposed at substantially the same horizontal position as the protrusion, and is distanced therefrom in the perpendicular direction, such that a distance between the position detector and the document in the perpendicular direction is substantially constant when the apparatus is in use, and such that the position detector has an unimpeded optical path through the window to the document when the apparatus is in use.
