An image reading device includes a shooting unit, a light source unit, a shooting controller, and a combining unit. The light source unit sequentially irradiates the bound document with light from first and second irradiation positions opposing each other with respect to a first straight line orthogonal to a direction of a binding portion of the document. The shooting controller controls the shooting unit to shoot a first region positioned at the second irradiation position side on the document when the light source unit irradiates the document with light from the first irradiation position, and controls the shooting unit to shoot a second region containing a region other than the first region on the document when the light source unit irradiates the document with light from the second irradiation position. The combining unit combines a shot image of the first region and a shot image of the second region.

An imaging device includes photoelectric conversion elements arranged unidirectionally for each color of light to be received, and performing photoelectric conversion of reflected light from an approximately same position of an object for the each color sequentially pixel by pixel; and a black correction unit that corrects a black level of the object with respect to a pixel group including some photoelectric conversion elements in a way that an output result of the photoelectric conversion of reflected light by a photoelectric conversion element for a pixel, independent of the reflected light, is subtracted from another output result of photoelectric conversion of reflected light by the photoelectric conversion element for the same pixel.

An improved synthetic resin spout stopper to be combined with a discharge port of a container is provided. The spout stopper does not pose difficulty in breaking an annular score formed in an annular flange wall, when discarding the container. Damage to the annular score is avoided even if a considerably great impact is applied to the spout stopper owing to a fall of the container. Damage to the annular score is also avoided even when ultrasonic welding is adopted for welding the container and the spout stopper together. In an inner peripheral edge part of the annular flange wall, an annular additional score is disposed adjacent to the annular score radially outwardly of and/or radially inwardly of the annular score.

A reference-signal generating unit generates a reference signal for generating a driving signal to drive other units of the image reading device. A frequency modulating unit modulates frequency of the reference signal, thereby generating a frequency-modulated reference signal. A driving-signal generating unit generates the driving signal from the frequency-modulated reference signal. A photoelectric converting unit converts an incident light into an analog image signal using the driving signal. An AD converting unit converts the analog image signal into a digital image signal. A correcting unit corrects the digital image signal by generating a correction signal for eliminating a noise superimposed on the digital image signal using the frequency-modulated reference signal and adding the correction signal to the digital image signal.

An image reading device includes a processing circuit having a clamp unit that matches an offset potential of an inputted analog image signal to a predetermined value, a processing unit that subjects an analog image signal obtained from the clamp unit to analog processing, and a converting unit that converts a processed analog image signal to a digital image signal. A control unit for controlling the processing circuit includes a switching unit that switches a main scanning line period of a charge coupled device and outputs analog image signals using a number of reading speeds, and a changing unit that changes a clamp period depending on the main scanning line period.
