Image reading apparatus

An image reading apparatus comprising:

• an image reading part that reads an image formed on a recording medium;
• an accommodating unit that accommodates the image reading part and supports the image reading part in such a manner that the image reading part is capable of being displaced toward a side on which the recording medium is to be disposed;
• and
• an urging member that urges, in the accommodating unit, the image reading part toward the side on which the recording medium is to be disposed,
• wherein the accommodating unit includes an urging-member-mounting portion in which the urging member is mounted,
• wherein at least one window is formed in the urging-member-mounting portion on a side opposite to a side on which the image reading part is disposed,
• wherein the urging member abuts a wall which longitudinally extends in a direction substantially perpendicular to a direction in which the urging member urges the image reading part,
• wherein the window is formed in the wall,
• wherein in a radial direction of the urging member, the window extends further away from a center of the urging member than a circumference of a portion of the urging member abutting the wall, and
• wherein in the radial direction, an innermost opening of the wall is closer to a radial, outer-edge of the spring than to a radial center of the spring, the innermost opening being a closest portion of the window to the radial center of the spring.
