    摘要: To provide an illumination device in which there is no variation in light intensity distribution of the illumination device, and in which illumination spots, particularly light intensity spots, are not prone to occur in a read image in an image reading device, by maintaining a constant gap between a light source and an end face of a light guide. The illumination device includes: a light guide having an end face for taking in light, a diffuse reflecting surface for diffusely reflecting the light taken in from the end face, and a light exit surface for emitting the light that is diffusely reflected at the diffuse reflecting surface towards an irradiation surface. The illumination device further include a reflector having a diffuse reflecting surface that reflects light from the light source toward the one end face of the light guide. The light guide has, at the one end, a flange portion that abuts the reflector, the light source is mounted to a circuit board, and the reflector is held between the flange portion of the light guide and circuit board so as to maintain a predetermined gap between the light source and light guide.

    摘要: A reading unit (3) placed on the inner side of a U-shaped feed path (12) that feeds a document is formed such that the height-axis dimension of said reading unit decreases in a direction extending toward a side having a paper delivery tray (11). Contact glass (20), a light source and a first mirror (24) are placed in the reading unit (3) at an end portion of the side having the paper delivery tray (11). Multiple reflecting mirrors (25, 26 and 27), a lens (28) and a photoelectric converter element (29) are placed further from the paper delivery tray than the first mirror (24) in the reading unit. This structure enables the reading unit provided in a document feeder to be more compact while ensuring the required light path length, and enables the entire document feeder to be more compact.

    摘要: Provided is a document reading device capable of performing shading correction and making it difficult for foreign matters to enter inside the device. A document reading device includes a reading unit, a glass unit, and a closing member. The reading unit has a light source and reads a document. The glass unit has a glass plate that transmits light emitted from the light source and a reference member serving as a reference for shading correction of a reading optical system. The glass unit is disposed with a space provided with respect to the reading unit and slid between a first position where the light emitted from the light source transmits the glass plate and a second position where the light emitted from the light source reaches the reference member with the space being maintained. The closing member is positioned downstream of the glass plate and the reference member of the glass unit in a document conveying direction and fills at least a part of the space provided between the reading unit and the glass unit.
