摘要:
An image scanner has a scanning unit which captures an image of an original placed on a platen, a scanning unit moving mechanism which moves the scanning unit in an auxiliary scanning direction, and an image processing unit which processes the image of the original scanned by the scanning unit. The image processing unit includes a sheet size candidate determining unit which determines sheet size candidates based on a width of the original, and a scan/non-scan section determining unit which determines a non-scan section and a scan section based on the sheet size candidate. The scanning unit moving mechanism moves the scanning unit at a first speed in the scan section and at a second speed which is faster than the first speed, and the scanning unit scans the image of the original in the scan section and does not scan the image in the non-scan section.

An image processing apparatus includes a receiving unit and a first difference extracting unit. The receiving unit receives images of a document. The first difference extracting unit performs difference extracting processing for extracting a difference between images of a document having 2n (n=2, 3, . . . ) pages received by the receiving unit by comparing the image of the first page and the image of the (n+1)-th page, the image of the second page and the image of the (n+2)-th page, the image of the third page and the image of the (n+3)-th page, . . . , and the image of the n-th page and the image of the 2n-th page.

An auto-document feeder includes: a document placing section on which an original document is placed; a sheet detection sensor configured to detect the original document, length in a feeding direction of the original document being first length larger than second length; a length detection sensor configured to detect the length of the original document while the original document is fed; a first feeding path for feeding the original document to a reading section for reading an image of the original document; a second feeding path for feeding the original document to the reading section, the second feeding path being different from the first feeding path; a switching section configured to selectively switch the first feeding path and the second feeding path; and a control section configured to divert, with the switching section, the original document to the first feeding path if the sheet detection sensor detects the original document.

A sheet processing apparatus includes a sheet-table unit, a sheet-separating unit, a convey unit, a discharge unit, a sheet processing unit, and a sensor arranged at an upstream end of the convey unit and spaced from the discharge unit with a predetermined distance. The convey unit has at least one convey roller, at least one convey pulley, and an elastic device connected with the convey pulley. The elastic device has a stepping motor, a transmission system, a shaft and at least one torsional spring mounted on the shaft. Two ends of the torsional spring is connected with the convey pulley. When the signal resulted from a rear end of the sheet apart from the sensor is sent to the system controller, the stepping motor is commanded by the system controller to rotate the shaft. The torsional spring is twisted to make the convey pulley move away from but still contact with the convey roller.

A wide image scanner which can scan the image of a large scale original using only a regular image sensor is provided. The invention includes a sliding shaft, an image reading device, a number of paper width sensors, a paper edge sensor, and a control module. Whenever the paper edge sensor detects the presence of an end edge of the original, it will send a vertical control signal to the control module to control the rotation direction of the rollers. On the other hand, the paper width sensors detect the width of the original and send the horizontal control signals to the control module. From the horizontal control signals, the control module can determine the number of horizontal displacement positions and control the horizontal displacement each time for the image reading device after the paper edge sensor detects the end edge of the original. The procedure continues until the image reading device has been moved to the final displacement position predetermined by the horizontal control signal. Consequently, the entire image of the origin can automatically be read portion by portion without manual operation.

An image forming apparatus to copy a two-sided card is disclosed. The image forming apparatus includes a user interface unit to adjust a layout for copying both sides of the two-sided card, an image reading unit to read the both sides of the two-sided card and generates scanned images, a controlling unit to generate image data where the scanned images are laid out on at least one page according to the adjusted layout, and an output unit to output the image data generated by the controlling unit. Accordingly, the both sides of the two-sided card may be laid out and output in various types.
