20100078874 | DOCUMENT FEEDER, METHOD FOR CONTROLLING THE SAME, AND RECORDING MEDIUM - A document feeder to reverse a document by conveying the document to a reverse path. The document feeder includes a conveyance roller to convey the document, a reverse roller provided along a conveyance path of the document conveyed by the conveyance roller to convey the document to the reverse path by changing a direction of conveyance of the document, and a reverse roller control unit to control the reverse roller to correct skew of the document. The reverse roller control unit controls the reverse roller to correct the skew of the document by striking the document conveyed by the conveyance roller against a nip formed between the reverse roller and a roller provided opposite the reverse roller to temporarily bend the document. | 04-01-2010 |
20110311241 | APPARATUS AND METHOD OF CONTROLLING AN IMAGE FORMING APPARATUS - A controller for controlling an image forming apparatus having a light detection unit controls at least two operations including: 1) operation of detecting a jam of a recording sheet in a sheet transfer path based on a light intensity level detected by the light detection unit when image forming is performed; and 2) operation of controlling switching of an operation mode of the image forming apparatus to an energy save mode based on a light intensity level detected by the light detection unit. | 12-22-2011 |

20130033166 | LIGHTING APPARATUS - A lighting apparatus includes a light source module, a power supply circuit section supplying power to the light source module, a heat radiating section accommodating the power supply circuit section inside and radiating the heat generated in the power supply circuit section, a base connected to an external power supply, and an insulating ring provided between the heat radiating section and the base and making electrical insulation. With regard to the lighting apparatus, the insulating ring is a thermal conductor. Since the insulating ring functions as the thermal conductor, the heat generated in the power supply circuit section is transferred to the heat radiating section and the base via the insulating ring so that the heat is radiated to outside from the heat radiating section and the base. | 02-07-2013 |
