  • Publication number: 20210313855
    Abstract: One embodiment of the present invention relates to a rotor and a motor having same, the rotor comprising: a rotor core; and a plurality of magnets arranged to be spaced apart from each other on an outer circumferential surface of the rotor core, wherein the rotor core includes: a body; and protrusions protruding obliquely inward at a predetermined angle from an inner circumferential surface of the body, wherein a predetermined gap (G1) is formed between the inner circumferential surface of the body and the end of each of the protrusions. Accordingly, the rotor and the motor having the same may minimize the amount of change in the outer circumferential surface of the rotor core by using the protrusions. As a result, it is possible to inhibit separation of the magnets attached to the outer circumferential surface of the rotor core.

  • Patent number: 6282325
    Abstract: In an image processing technique for binarizing an image scanned by a shuttle type scanner in a multifunctional machine using a small amount of memory, after scanning pixels of one slice from a document, each pixel of the scanned slice are binarized using a mask. The processing results of the error values generated during binarizing of final pixels of a plurality of slices of the band are stored in a first memory, and the processing results of error values generated during binarizing of each of the pixels of the scanned slice are stored in a second memory. When each of the first pixels of a plurality of slices in the next band are binarized, the processing results of the error values of the final pixels of a plurality of slices in the previous band, stored in the first memory, are scanned and then binarized. By using minimum band memories, the cost of the multifunctional machine can be reduced.

  • Patent number: 6276771
    Abstract: A multifunctional machine for scanning and printing and a scanning and printing method used in the multifunctional machine are capable of reducing the volume of the multifunctional machine and reducing data amount relative to parts other than a document when scanning a document smaller than a reference size document. The document or a printable medium is fed in a sub-scanning direction by a feeding unit. A scanner module scans the document by performing shuttle movement in a main scanning direction perpendicular to the sub-scanning direction, and a printer module is established next to the scanner module in the sub-scanning direction for printing data onto the printable medium. In addition, a white panel is located facing the bottom side of the scanner module in the main scanning direction, and a black panel is located facing the bottom side of the printer module in the main scanning direction.
