Abstract
An image reading apparatus for reading an original document including: a light source including a sheet-shaped light-emitting section which includes an electroluminescence element, the light emitting section being configured to have a folded plane folded inward or a concave curved surface, and a light emitting surface being arranged inside the folded plane or the concave curved surface; and a reading element which receives light from the original document to read images while the light source illuminates a reading position of the original document along a main-scanning direction of the original document.
Claims8
An image reading apparatus for reading an original document comprising:
- a light source including a sheet-shaped light-emitting section which comprises an electroluminescence element, the light emitting section being configured to be a form of a rectangle whose long side is in a main-scanning direction of the original document, and is folded or bent in a short side direction to have a folded plane folded inward or a concave curved surface, and a light emitting surface being arranged inside the folded plane or the concave curved surface;
- and
- a reading element which receives light from the original document to read images while the light source illuminates a reading position of the original document along a main-scanning direction of the original document.
An image reading apparatus for reading an original document comprising:
- a light source including a sheet-shaped light-emitting section which comprises an electroluminescence element, at least a part of end portions of the sheet-shaped light emitting section being configured to be a form of a rectangle whose long side is in a main-scanning direction of the original document, and is folded or bent in at least one end portion of a long side direction and short side direction to have a folded plane folded inward or a concave curved surface, and a light emitting surface being arranged inside the folded plane or the concave curved surface;
- and
- a reading element which receives light from the original document to read images while the light source illuminates a reading position of the original document along a main-scanning direction of the original document.
A light source of an image reading apparatus for illuminating a reading position of the original document along a main-scanning direction of the original document, the light source comprising:
- a sheet-shaped light-emitting section which comprises an electroluminescence element, wherein the light emitting section being configured to be a form of a rectangle whose long side is in a main-scanning direction of the original document, and is folded or bent in a short side direction to have a folded plane folded inward or a concave curved surface, and a light emitting surface being arranged inside the folded plane or the concave curved surface.
A light source of an image reading apparatus for illuminating a reading position of the original document along a main-scanning direction of the original document, the light source comprising:
- a sheet-shaped light-emitting section which comprises an electroluminescence element,
- wherein the light emitting section is configured to be a form of a rectangle whose long side is in a main-scanning direction of the original document, and is folded or bent in at least one end portion of a long side direction and short side direction to have a folded plane folded inward or a concave curved surface, at least a part of end portions of the light emitting section being configured to have the folded plane folded inward or the concave curved surface, and a light emitting surface being arranged inside the folded plane or the concave curved surface.
