    Abstract: Deformation of a second optical carriage (B) due to heat is large on a (C) side where an inverter (31) is attached and small on a (D) side. A mirror supporting portion inside the second optical carriage (B) supports the mirror at one point on the (C) side and at two points on the (D) side. An angle of the reflecting mirror (8) depends on two protrusions on the (D) side where thermal deformation is small, and the mirror is supported at one point on the (C) side where thermal deformation is large. Thus, even if an angle of the mirror supporting portion (C) changes, the angle of the reflecting mirror (8) is not affected. Therefore, a change in the angle of the reflecting mirror (8) can be controlled to be small when temperature of the second optical carriage (B) rises during a reading operation, and decrease in reading accuracy due to thermal deformation of the second optical carriage (B) can be suppressed.

    Abstract translation: 在（C）侧安装逆变器（31）并且在（D）侧小的情况下，由于热而导致的第二光学滑架（B）的变形大。 第二光学滑架（B）内的反射镜支撑部分在（C）侧的一点和（D）侧的两点处支撑反射镜。 反射镜（8）的角度取决于热变形小的（D）侧的两个突起，并且反射镜被支撑在热变形大的（C）侧的一点处。 因此，即使反射镜支撑部（C）的角度变化，反射镜（8）的角度也不受影响。 因此，当在读取操作期间第二光学支架（B）的温度升高时，反射镜（8）的角度的变化可以被控制得很小，并且由于第二光学支架的热变形引起的读取精度的降低 （B）可以被抑制。

    Abstract: An image reading apparatus includes an illumination unit that illuminates light on an image surface of a sheet, and a photoelectric conversion element that converts reflected light from the sheet illuminated by the illumination unit into an electric signal. The illumination unit includes a circuit board including a light emitting element, and a light guide that guides light, emitted from the light emitting element, to a sheet read surface. In the image reading apparatus, the light guide includes a positioning surface that abuts against a first surface of the circuit board and that performs positioning of the light guide and the circuit board, and a pressing portion that abuts against a second surface of the circuit board on an opposite side of the first surface and that presses the circuit board against the positioning surface.

    Abstract: A light guide includes a plurality of boss portions. A round hole portion is provided near the center of a base member for fixing the light guide, and slit portions are provided on both ends thereof. The round hole portion supports one boss portion in both the longitudinal direction and the lateral direction of the light guide. The slit portions support boss portions in the lateral direction of the light guide, but are free in the longitudinal direction of the light guide. That is, the center of the light guide is fixed from both directions, and thus both ends of the light guides can expand away in the longitudinal direction. This cuts the influence of expansion by half.

    Abstract: A contact image sensor unit includes: a light source (10) illuminating an original; a rod-like light guide (11) guiding light from the light source to the original; an imaging element (12) forming reflected light from the original on a plurality of photoelectric conversion elements; a sensor substrate (14) on which the plurality of photoelectric conversion elements are mounted; a frame (15) to which they are attached and which has a positioning part (200) for attaching the light guide (11) thereto; and a supporting member (16) which attachably/detachably supports the light guide (11) and is attachably/detachably attached to the positioning part (200). Since the light guide (11) can be attached to the frame (15) without using an adhesive, the deformation of the light guide (11), the warpage of the contact image sensor unit and so on can be prevented.
