Abstract

An image reading apparatus includes a reader that reads an image of a document by using plural light receiving elements arranged in a first scanning direction; a moving unit that moves the reader in a second scanning direction to move a reading position at which the reader reads the document; and an adjusting unit that moves the reader in the first scanning direction to adjust a position of the reader in the first scanning direction.

First claim

1 . An image reading apparatus comprising:
a reader configured to read an image of a document by using a plurality of light receiving elements arranged in a first scanning direction; a moving mechanism configured to move the reader in a second scanning direction to move a reading position at which the reader reads the document; an adjusting mechanism configured to move the reader in the first scanning direction to adjust a position of the reader in the first scanning direction; a second container that contains the reader; and a support member that supports the screw and that is located at a position fixed relative to the second container, wherein the screw is configured to move relative to the support member so that the reader is moved relative to the second container in the first scanning direction wherein the adjusting mechanism includes a screw that is configured to move in the first scanning direction to adjust the position of the reader.

2 . The image reading apparatus according to claim 1 , further comprising:
a first container in which the reader, the moving mechanism, and the adjusting mechanism are contained, wherein the first container has an opening that enables the adjusting mechanism to be operated from the outside of the first container.

3 . The image reading apparatus according to claim 2 , wherein the opening is formed in a front surface of the first container, the front surface serving as an operation surface used to operate the image reading apparatus.

4 . (canceled)

5 . (canceled)

6 . The image reading apparatus according to claim 1 , wherein the second container is a resin component, and the support member is made of a metal.

7 . The image reading apparatus according to claim 1 , wherein the support member is fixed to the second container in the first scanning direction even when the screw is not present.

8 . The image reading apparatus according to claim 1 , further comprising:
an elastic member that elastically urges the reader toward the screw, wherein the moving mechanism is configured to move the second container in the second scanning direction to move the reader in the second scanning direction.

9 . The image reading apparatus according to claim 1 , further comprising:
a first container in which the reader, the moving mechanism, and the adjusting mechanism are contained; an urging member that urges the reader; and a platen glass that is directly or indirectly supported by the first container, wherein the adjusting mechanism is capable of adjusting the position of the reader while the reader is disposed between the urging member and the platen glass.

10 . An image reading apparatus comprising:
a reader configured to read an image of a document by using a plurality of light receiving elements arranged in a first scanning direction; a moving mechanism configured to move the reader in a second scanning direction to move a reading position at which the reader reads the document; an adjusting mechanism configured to move the reader in the first scanning direction to adjust a position of the reader in the first scanning direction; and a first container in which the reader, the moving mechanism, and the adjusting mechanism are contained, wherein the first container has an opening that enables the adjusting mechanism to be operated from the outside of the first container without opening a side of the first container.

11 . An image reading apparatus comprising:
a reader configured to read an image of a document by using a plurality of light receiving elements arranged in a first scanning direction; a moving mechanism configured to move the reader in a second scanning direction to move a reading position at which the reader reads the document; an adjusting mechanism configured to move the reader in the first scanning direction to adjust a position of the reader in the first scanning direction; a second container that contains the reader, the moving mechanism configured to move the second container in the second scanning direction to move the reader in the second scanning direction; and an elastic member that elastically urges the reader toward the screw.
