Abstract
An image reading apparatus including: a reading unit configured to read an image of an original in a main scanning direction; a housing configured to accommodate the reading unit; a guide member configured to guide a movement of the reading unit in a sub-scanning direction orthogonal to the main scanning direction; and a restricting member configured to restrict the movement of the reading unit in the sub-scanning direction and a movement of the reading unit in a vertical direction orthogonal to the main scanning direction and the sub-scanning direction.
Claims11
An image reading apparatus comprising:
- a platen on which an original is placed;
- a reading unit configured to read an image of the original placed on the platen in a main scanning direction while moving in a sub-scanning direction orthogonal to the main scanning direction;
- a housing configured to accommodate the reading unit and support the platen;
- a guide shaft extending in the sub-scanning direction and fixed to the housing, the guide shaft being configured to guide a movement of the reading unit in the sub-scanning direction;
- a sliding member provided to the reading unit and configured to slide on the guide shaft;
- and
- a restricting member provided to the reading unit and including protruding portions which are disposed under the guide shaft and which protrude in the main scanning direction,
- wherein the protruding portions are disposed in different positions, respectively, in the sub-scanning direction, and
- wherein the sliding member and the protruding portions abut against the guide shaft to restrict a movement of the reading unit in a vertical direction orthogonal to the main scanning direction and the sub-scanning direction.
