摘要： A sheet-fed scanner comprising a scan channel, a feeding unit, a transmitting unit, a background sheet, a background light source and a scan module is provided. The feeding unit is disposed at an inlet of the scan channel for feeding a document. The transmitting unit transmits the document to pass through the scan channel. The background sheet is disposed on a side of the scan channel, and has a first surface and a second surface. The first surface faces towards the scan channel. The background light source faces towards the second surface to provide an intermittent light signal to the background sheet, so that the background sheet correspondingly displays an intermittent variation background image on the first surface. The scan module is disposed on another side of the scan channel, and captures a document image of a document and the intermittent variation background image to generate scan data accordingly.

摘要： An image forming apparatus includes an exposing section, a pulse generating section, a frequency storing section, an emission control section, a smoothing section, and a driving-current generating section. The pulse generating section generates a periodic pulse signal indicating light amount of light beam emitted by a light source of the exposing section. The frequency storing section stores in advance a plurality of frequencies of the pulse signal. The emission control section selects, in the rendering of each main scanning line, any one of the plurality of frequencies and instructs the pulse generating section to generate the pulse signal having the selected frequency. The smoothing section smoothes the pulse signal generated by the pulse generating section according to the instruction of the emission control section and generates analog signal. The driving-current generating section generates driving current for the light source of the exposing section on the basis of the analog signal.

摘要： An analog front-end circuit includes an analog processing circuit, an A/D converter, a calculation circuit, and a target register in which a black level target value is set. The analog processing circuit includes a clamp circuit that performs a line clamp operation, and an offset adjustment circuit. The calculation circuit monitors an A/D-converted value of a black reference pixel after the line clamp operation in a black level monitor period after a line clamp period but before an effective pixel output period, and performs a black level error correction process by writing an offset adjustment value that causes the A/D-converted value to be set at the black level target value into the offset adjustment register.

摘要： A method for creating frame data used when forming an image by moving a spatial light modulation device including a plurality of plotting element arrays in a scanning direction which forms an inclination angle θ with an arrangement direction of the plotting element arrays, and sequentially inputting the frame data to the spatial light modulation device according to the movement of the device in the scanning direction. The method is based on image data in which pixel data are disposed two-dimensionally in a sub-scanning direction corresponding to the scanning direction, and a main scanning direction orthogonal to the sub-scanning direction, and the frame data are created after performing a deformation process on the image data such that the pixel data corresponding to each of the plotting element arrays (e.g., circled numbers 1 to 6) are disposed in the main scanning direction.

摘要： A linear guiding mechanism for a platform type optical scanner. A V-shaped track is installed inside a casing and positioned parallel to the travel path of a carrier chassis containing a system of optical devices. The upper section of the V-shaped track has a pair of support surfaces forming an included angle. The V-shaped track supports a positioning wheel or a positioning bump attached to the carrier chassis. The carrier chassis moves along the longitudinal direction of the V-shaped track when driven by a driving system. The V-shaped track may be constructed from a pair of monorails so that the driving belt may move inside the space between the monorails. An additional positioning structure may attach to the interior sidewall of the casing to serve as a retainer for the chassis in an initial position.
