    Abstract: An image reading apparatus of the present invention includes a first light source, a first light guide, a second light source, a second light guide, light receiving elements and a lens unit. The first light source emits first light. The first light guide directs the first light from the first light source toward an image-carrying object as first linear light extending in a primary scanning direction. The second light source emits second light of a wavelength different from that of the first light. The second light guide directs the second light from the second light source toward the image-carrying object as second linear light extending in the primary scanning direction. The light receiving elements are arranged in the primary scanning direction. The first and second linear lights are reflected by the image-carrying object, and the reflected lights are guided by the lens unit toward the light receiving elements.

    Abstract: There are provided a light emitting unit in which temperature increase due to heat generated in a light emitting element is suppressed to enhance light emission efficiency, a linear illumination device in which the light emitting unit is incorporated, and a contact-type image sensor and an image scanner in which the linear illumination device is incorporated. A lead frame 23 in the light emitting unit has an extension 29. The extension 29 is folded along a case 12, and a plate-shaped heat dissipater 30 is connected to the extension 29. The connection is carried out by forming holes 29a and 30a in the extension 29 and the heat dissipater 30, respectively, and engaging a protrusion 31 formed on the case 12 in the holes 29a and 30a. The extension 29 thus comes into tight contact with the heat dissipater 30 and is fixed thereto. The heat dissipater 30 is made of a good thermally conductive material, such as copper, and formed separately from the lead frame 23.

    Abstract: An image reader for reading an image drawn on a paper or a sheet-like recording medium, an image processor provided with the image reader, such as a copying machine, a scanner and the like, and a fiber lens to be applied to those devices. The image processor has to be large in the whole size of device to read both sides of an original. Therefore, the image processor of the present invention comprises an image reader (10a) on the upper side of transport path and an image reader (10b) on the lower side of that respectively. In order to downsize the device, it is necessary to shorten the diameter of optical fiber (140) of the fiber lens (14) installed in the imager reader as light receiving means. In this case, the optical fiber (140) is provided with a light-absorbing layer 8(143) around of the optical fiber (140) in order to restrain the crosstalk and the flare phenomenon. The illuminance of light source means (15) installed in the image reader gets smaller as the device is downsized. In case where the illuminance is small, the image quality is deteriorated by the floating of the original. Accordingly, the image reader should be provided with the light source means so as to uniform the illuminance over a specific width of the main and sub scanning directions. Therefore, it is possible to avoid the deterioration of the image quality.
