摘要： 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.

摘要： 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.

摘要： A clock-signal generating unit generates temporally-continuous clock signals. A spread-spectrum clock-signal generating unit generates a spread-spectrum clock signal by modulating a frequency spectrum of a clock signal generated by the clock-signal generating unit. A signal delaying unit generates a fixed delay unaffected by a spread spectrum from the spread-spectrum clock signal generated by the spread-spectrum clock-signal generating unit, and delays a phase of the spread-spectrum clock signal based on an amount of the fixed delay.

摘要： 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.
