Abstract: A light-emitting unit 20 has a light-emitting unit board 21 made of resin provided with a lead frame 22. The light-emitting unit board 21 is also provided with an open window 21a for mounting a light-emitting device. The lead frame 22 comprises a lead terminal section 22a, an inner lead section 22c, and a light-emitting device mounting and connecting section 22b which is exposed within the open window 21a. The light-emitting devices 23a, 23b, and 23c are bonded with the light-emitting device mounting and connecting section 22b, and electrodes of the light-emitting devices and the lead frame are connected by a metal wire 24, wherein the open window 21a is sealed by transparent resin. The lead frame 22 is made of iron-containing copper to improve heat radiation performance of the light-emitting unit board. By increasing maximum current to be supplied to the light-emitting diodes, it is possible to increase illumination brightness and to attain speedup of image reading.

Abstract: An image reading apparatus includes a line light source having a light guide plate and red-, green-, and blue-LEDs, for a light transmitting original, and a contact image sensor unit for detecting light from the line light source. The light transmitting original is arranged between the line light source and the contact image sensor unit. The light transmitting original is read by moving the line light source and the contact image sensor unit relative to the light transmitting original. The line light source is moved interlockingly with the contact image sensor unit by the attraction between a magnet provided at both ends of the line light source in the longitudinal direction thereof and a magnet provided at both ends of the contact image sensor unit in the longitudinal direction thereof.

Abstract: A light guide 11 of a rectangular cross-section has side faces 11a, 11b including short sides in the longitudinal direction of which one side face 11a is provided with a light-scattering pattern 20, formed by screen-printing in white paint, for scattering the light incident to the light guide 11. The other side face 11b facing the side face 11a is exposed from a casing 12 to serve as a light-emitting surface. In the present embodiment, it is possible to secure a sufficient amount of light because the whole area of the side face is used as the light-emitting surface. The remaining side faces 11c, 11d of the light guide 11 are side faces including the long sides. Since the side faces 11c, 11d easily produce a surface sink during molding, neither the light-scattering pattern 20 nor the light-emitting surface is provided thereon.

Abstract: An image reading apparatus of a contact image sensor type includes an area light source. The image reading apparatus is used for reading a light transmitting original placed on an original base by irradiating light thereto from the area light source and receiving transmission light. The original base has an uneven portion on a front surface on the side on which the light transmitting original is placed so that the adhesion of the light transmitting original to the original base is prevented upon placing the light transmitting original on the original base. The uneven portion does not effect optical characteristics for reading the light transmitting original.
