Image Reading Apparatus
First Claim
1. An image reading apparatus comprising:
- a reading unit including;
a support surface configured to support a document thereon; and
a reading sensor configured to read an image of the document supported on the support surface;
a cover including a conveying unit, the conveying unit being disposed above the reading unit and configured to convey a document to the reading sensor, the cover being pivotable about a pivot axis between a closed position and an open position relative to the support surface, the pivot axis extending in a first direction, and the cover including a first end and a second end in the first direction, the second end being opposite to the first end in the first direction;
a hinge mechanism connecting the cover to the reading unit pivotably about the pivot axis, the hinge mechanism including a first hinge which includes;
a base member movably disposed in the reading unit, the base member being movable in a second direction orthogonal to the support surface; and
a pivot member supported by the base member pivotably about the pivot axis and coupled to the cover,wherein the conveying unit and a center of gravity of the cover are both closer to the first end of the cover in the first direction than to the second end of the cover,wherein the first hinge is spaced from the center of gravity toward the second end of the cover in the first direction, and the hinge mechanism further includes a second hinge disposed closer to the center of gravity in the first direction than the first hinge, andwherein the first hinge further includes an urging member configured to exert an urging force between the base member and the pivot member so as to maintain the cover at a pivoted positon between the closed position and the open position.

Abstract
An image reading apparatus includes a reading unit, a cover, and a hinge mechanism connecting the cover to the reading unit pivotably about a pivot axis which extends in a first direction. A center of gravity of the cover is closer to a first end of the cover in a first direction than to a second end of the cover. A first hinge is spaced from the center of gravity toward the second end of the cover in the first direction. A second hinge is disposed closer to the center of gravity in the first direction than the first hinge. The first hinge includes a base member disposed movably in the reading unit, a pivot member coupled to the cover, and an urging member exerting an urging force between the base member and the pivot member so as to maintain the cover at a pivoted position.
