Light emitting device, image reading device, and image forming apparatus

A light emitting device comprising:

• a light-guide member that extends in one direction;
• a light emitting element that radiates light onto an end surface of the light-guide member;
• a reflective member that extends in the one direction and reflects, while holding the light-guide member, light that is emitted from a surface of the light-guide member;
• and
• a housing that accommodates the reflective member and includes a holding unit, the holding unit being configured to hold the reflective member at an accommodating position of the reflective member and configured to allow the reflective member to be released from a state of being held when the reflective member is bent in a crossing direction that crosses the one direction, and
• wherein the holding unit includes
• a plurality of first restricting portions that are arranged on a first side in the crossing direction with respect to the reflective member in such a manner as to be spaced apart from one another in the one direction and that restrict movement of the reflective member toward the first side in the crossing direction by being brought into contact with the reflective member,
• a pressing portion that is disposed on a second side in the crossing direction with respect to the reflective member and that presses the reflective member against the first restricting portions, and
• a second restricting portion that is disposed on the second side in the crossing direction with respect to the reflective member in such a marmer as to be located at a position displaced from the first restricting portions in the one direction and that restricts movement of the reflective member in another crossing direction that crosses the one direction and the crossing direction by being brought into contact with the reflective member in the other crossing direction, and
• wherein the reflective member is bent in such a manner that a portion of the reflective member that is in contact with the second restricting portion moves toward the first side in the crossing direction, so that the reflective member is allowed to be released from the state of being held.
