Abstract: A controller controls a scanner unit of an image reading device to read a section of an original document that corresponds to an image reading area specified by a user, when a user instruction for setting the image reading area is received. The controller causes the scanner unit to move to an image reading start position in a sub-scanning direction as specified by a user instruction. When a user instruction for starting image reading is received, the controller causes the scanner unit to start reading the section of the original document from the image reading start position.

Abstract: An image reading apparatus includes a light source unit, an image sensor, and a light guiding unit at least including a light reflector. The light guiding unit may include a first masking shield and a second masking shield. The light source unit irradiates light toward an original. The image sensor picks up an image of the original based on reflected light of the light by the original. The light guiding unit is provided on an opposite side to the light source unit to cause a part of the light to directly enter into the image sensor, when the original is not fed to the image sensor. The light guiding unit reduces light incident to the image sensor, among the light and light having transmitted through the original, at the time of picking up the image of the original by the image sensor.

Abstract: An image reading apparatus which is capable of performing accurate shading correction with simple arrangement while preventing a reference member from being scratched and paper powder and the like dust from being deposited on the reference member. The image reading apparatus comprises an image reading unit. In the image reading unit, a contact glass guides an original on an image reading location. The contact glass is held by a glass holding member. A line image sensor reads the image on the original conveyed on the image reading location, through the contact glass. The image reading unit further comprises a reference member whose image is readable by the image sensor, and a moving mechanism to move the image sensor so as to enable the image sensor to alternatively read the original and a reference surface of the reference member.

Abstract: An image scanning device includes an image sensor obtaining an analog image signal; a variable gain amplifier amplifying the analog image signal; an analog-to-digital converter converting the amplified analog image signal into digital image data; a highest value detection unit detecting the highest value in the digital image data; and an amplifier gain setting unit setting an amplifier gain of the variable gain amplifier. The amplifier gain setting unit initially sets the amplifier gain of the variable gain amplifier such that the highest value in first digital image data of a reference image falls within a predetermined range, and if the highest value in second digital image data of the reference image obtained with the initially-set amplifier gain exceeds the predetermined range, the amplifier gain setting unit decreases the amplifier gain of the variable gain amplifier.
