  • Patent number: 10136012
    Abstract: An image reading apparatus that is capable of determining whether an original is a blank-paper original without stopping a reading operation. A feeding unit feeds an original to a read position. A read unit is equipped with a plurality of line sensors that read the original at the read position. An obtaining unit obtains dust-position information about dust adhering to the read position based on image information that is obtained by reading a guide member arranged corresponding to the read position with the read unit before reading the original. A determination unit determines whether the original is a blank-paper original using image information corresponding to pixels without being affected by the dust that is obtained by excluding image information corresponding to the dust-position information from image information read by the line sensors of the read unit.

    Abstract: A linear light source device illuminates a document properly, and an image reading device includes such a light source device. The light source device includes a light source and a light-guiding member. The light-guiding member introduces the light emitted from the light source from one end portion in x-direction, cause the light to travel in x-direction, and emits the light from a light exit portion at one end in z-direction, which is orthogonal to x-direction. The light-guiding member includes, at the other end in z-direction, a light-reflecting portion that reflects light to the light exit portion. One end face of the light-guiding member in y-direction, which is orthogonal to x- and z-directions, is inclined so as to become closer to the other end face in y-direction with decreasing distance from the light exit portion in z-direction. This allows light to easily travel to the light-reflecting portion.

  • Patent number: 8908239
    Abstract: Since a light emitting surface in a cross section perpendicular to the longitudinal direction of a light guide is formed to have a smaller width than a reflecting surface, light of an LED, which is incident from an end surface of the light guide and is scattered throughout the entirety of the longitudinal direction in the reflecting surface, is condensed toward the light emitting surface, and is then emitted in the form of a band toward a document from the light emitting surface. Therefore, it is possible to provide a CIS module including an illumination unit having a new configuration capable of illuminating a portion where the document and an optical axis of the lens array included in the lens unit intersect, in the form of a band with high efficiency using the illumination unit.

    Abstract: An image-reading lens includes front-group and rear-group lens systems which are arranged on an object side and an image side, respectively. The front-group lens system includes equal to or less than 5 lenses which include at least one positive lens and at least one negative lens, and the rear-group lens system includes one negative lens. An angle of view of an entire system of the image-reading lens is equal to or more than 56°. The front-group and rear-group lens systems are structured such that with respect to a change in a distance between the front-group and rear-group lens systems, a change in a focal length of the entire system of the image-reading lens is small, and a change in an image plane is large, and by adjusting the distance between the front-group and rear-group lens systems, a required lens performance is obtained.

  • Patent number: 8861047
    Abstract: A document size detector sets an amount of light to be emitted from a light source for document size detection in accordance with the amount of disturbance light detected by the CCD, switches on the light source so as to make the light source emit the set amount of light, and detects the size of a document placed on a platen. Therefore, erroneous detection of a document size is prevented and glare that a user is subjected to when the size of a document placed on the platen is detected is reduced.

  • Patent number: 8854704
    Abstract: An image reading apparatus includes a light source unit, an image sensor, an attenuator, an analog processor and an A/D converter. The attenuator generates a second analog signal by voltage-dividing a first analog signal by two resistors. The analog processor generates a third analog signal by amplifying the second analog signal with a predetermined gain. The A/D converter converts the third analog signal into a digital signal. A voltage-dividing ratio of the attenuator is not higher than a ratio of a maximum value of the amplitude of a signal inputtable to the analog processor to a maximum value of the amplitude of a signal having a possibility of being output from the image sensor.
