Abstract
A contact-type image reading apparatus includes two image reading units each of which has light-receiving elements arranged two-dimensionally for reading an image on an original in two-dimensional directions, a first body unit which includes one of the two image reading units as a first image reading unit, and a second body unit which includes the other image reading unit as a second image reading unit disposed so as to be openable and closable with respect to the first body unit for sandwiching the original therebetween when the second body unit is closed. When the second body unit is closed, the second body unit is closed with respect to a surface where the first image reading unit is provided in the first body unit, and the second image reading unit is disposed to face the first image reading unit.
Claims7
A contact-type image reading apparatus comprising:
- two image reading units each of which includes a two-dimensional contact-type area sensor that includes a light-receiving/emitting layer having light-receiving elements arranged two-dimensionally on a transparent glass substrate and spaced apart from each other, and light-emitting portions arranged around the light-receiving elements, for reading an image on an original in two-dimensional directions without conveying the original and without mechanically scanning the original;
- a first body unit that includes one of the two image reading units as a first image reading unit;
- a second body unit that includes the other image reading unit as a second image reading unit, the second body unit being disposed so as to be openable and closable with respect to the first body unit for sandwiching the original between the first body unit and the second body unit when the second body unit is closed with respect to the first body unit;
- and
- an elastic member arranged between the first body unit and the first image reading unit so that the first image reading unit is mounted on the first body unit through the elastic member, wherein
- the second body unit is closed with respect to a surface where the first image reading unit is provided in the first body unit when the second body unit is closed with respect to the first body unit,
- the second image reading unit is disposed to face the first image reading unit when the second body unit is closed with respect to the first body unit,
- the second image reading unit is arranged to allow the original to be placed thereon when the second body unit is opened with respect to the first body unit, and
- the elastic member is arranged to generate a pressing force between the original and the two image reading units, when the first body unit and the second body unit are closed to sandwich the original therebetween, to make the original come into close contact with both the first image reading unit and the second image reading unit.
