Abstract: A scanning apparatus to scan and process one or more papers provided on a paper feeder, the scanning apparatus including a scan job identifier to identify one or more separate scan jobs within the papers provided on the paper feeder; and an image information processor to process image information to be stored in one or more separate respective files according to the one or more separate scan jobs.

Abstract: An image forming apparatus including a conveying unit for conveying a document, on which an image is recorded, along a predetermined conveying path, a scan unit that is disposed on the conveying path of the document for scanning the image recorded on the document, and a control unit for controlling the conveying unit and the scan unit. The control unit includes a main circuit board that controls operations of the scan unit and converts the scanned image into digital image information, and a sub-circuit board that controls operations of the conveying unit, and wherein the sub-circuit board includes a high voltage signal area on which a high voltage signal is routed, and a low voltage signal area on which a low voltage signal is routed.

Abstract: An image forming device, a method for processing image data, and a system for transmitting image data, with the image data transmission system including an image forming device reading out scan data to generate image data and compressing the generated image data into a predetermined or selected form for transmitting, and a wireless terminal device connected over a cable to the image forming device and receiving the compressed image data over the cable from the image forming device. Therefore, it is possible to transmit image data, although the image forming device has no dedicated communication module.

Abstract: An image forming apparatus, a feeder for an image forming apparatus and control method where: a feeding section feeds loaded papers to a main body of the image forming apparatus; a memory stores driving characteristic data of the feeding section; a function discrimination section discriminates a type of function to be performed by the feeding section; and a controller generates control data for controlling the feeding section to operate according to the discriminated type of function, based on, for example, the driving characteristic data. The control data is stored in a memory, and the driving of the feeding section is controlled by use of the stored control data when an execution command for a certain function is received from a main body control part. The control program, the controller, and the circuit board being utilized in the feeder additionally connected to the image forming apparatus may be generalized, whereby development and manufacture of the feeder may be facilitated.

Abstract: A V-cutter for use in manufacturing a light guide panel of the backlight unit in liquid crystal display (LCD), and more specifically, a kit with a plurality of pins for the V-cutter is disclosed. The pin kit may be used to form a plurality of V-shaped grooves spaced apart by a desired, varying interval on the light guide panel. The pin kit may include a buffer plate (10) fixed to a lift piece (7), an elastic member (11) fixed in the longitudinal direction at bottom thereof, a guide plate (14) in which insertion holes (15) for a plurality of pins (12) are formed to permit contact between the pins and the elastic member, and a plurality of pins (12) to be inserted into the insertion holes of the guide plate for forming V-shaped grooves (3) on the light guide panel (1).

Abstract: A method and an apparatus for detecting an error in an image scanning device that obtains image data upon scanning a document by using a light of beam radiated from a lamp, including a setting operation of obtaining initial reference values of a light quantity of the lamp and storing the obtained initial reference values in a memory, a storing operation of measuring the light quantity of the lamp during use of an image scanning system, obtaining measured values for comparing with the initial reference values, and storing the measured values in the memory, and a comparing/determining operation of determining whether to check the error to represent the lamp or a contaminant in an optical path by comparing the initial reference values with the measured values.

Abstract: A V-cutter for use in forming V-shaped grooves (3) on a light guide panel (1) of the backlight unit for a liquid crystal display (LCD) is disclosed. The V-cutter may include a Z-axis lift piece (7) and a W-axis lift piece (8), each of which has a pin kit (10a, 10b) with a plurality of pins (9a, 9b) attached at the bottom thereof. The pins (9a, 9b) are preferably equal in number and spacing to the V-shaped grooves (3) to be formed. The lift pieces (7, 8) may be vertically actuated by a Z-axis controller (5) and a W-axis controller (6). The light guide panel (1) is preferably fixtured to a table (11). The lift pieces (7, 8) are configured to move with respect to the table (11) so that, through successive X-axis and Y-axis operations, the V-shaped grooves can be formed in perpendicular directions with only two reciprocating motions. As a result, the manufacturing cost of the light guide panels (1) is reduced.
