An image reading apparatus includes an image reading chip for reading an image. The image reading chip includes a plurality of pixel units which include a light receiving element which receives light from the image so as to perform photoelectric conversion, an analog circuit, a logic circuit, and a power source pad to which a power source voltage is supplied. The image reading chip has a shape which includes a first side and a second side shorter than the first side. A distance between the analog circuit and a median point of the first side is shorter than a distance between the logic circuit and the median point of the first side, and a distance between the analog circuit and the power source pad is shorter than a distance between the logic circuit and the power source pad.

1. Technical Field
The present invention relates to an image reading apparatus and a semiconductor device.
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
FIG. 1 is an external perspective view illustrating a combination machine according to an exemplary embodiment.
FIG. 2 is a perspective view illustrating an internal structure of a scanner unit.
Hereinafter, a preferred exemplary embodiment according to the invention will be described in detail with reference to the drawings. The drawings are used to aid in the descriptions. The exemplary embodiment which will be described below does not unreasonably limit the details of aspects of the invention described in claims. All components of a configuration which will be described below are not limited as necessary components for the aspect of the invention.
Hereinafter, a combination machine (combination device) 1 to which an image reading apparatus according to an aspect of the invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an external perspective view illustrating the combination machine 1. As illustrated in FIG. 1, the combination machine 1 integrally includes a printer unit (image recording device) 2 which corresponds to a device main body, and a scanner unit (image reading apparatus) 3. The scanner unit 3 corresponds to an upper unit which is disposed at an upper portion of the printer unit 2. Descriptions will be made on the assumption that a front-rear direction in FIG. 1 is an X axis direction and a crosswise direction is a Y axis direction.
