Optical component mounting structure, image reading device including the same, and image forming apparatus including the same

An optical component mounting structure, comprising:

• an elastic member for applying pressure to an optical component toward a flat surface portion of a base;
• and
• a mounting portion that is provided at the base and to which the elastic member is mounted,
• wherein the elastic member has:
• a pressing portion that elastically comes in contact with the optical component;
• and
• a holding portion that supports one end of the pressing portion and holds elastically the mounting portion of the base,
• the optical component is placed so as to protrude with respect to an end surface of the base, and
• the pressing portion has:
• a first pressing portion that elastically comes in contact with a front part of the optical component with respect to a gravity center position of the optical component relative to a direction in which the optical component protrudes;
• and
• a second pressing portion that elastically comes in contact with a rear part of the optical component with respect to the gravity center position of the optical component relative to the direction in which the optical component protrudes.
