20100084808 | SHEET POST-PROCESS APPARATUS - A sheet post-process apparatus includes a waiting tray and a processing tray. The waiting tray is provided in the middle of a conveying path and makes standby sheets in the case where a post-process is required. The processing tray has a function which causes the sheets made standby on the waiting sheet to be dropped by self-weight. With this function, the processing tray receives the sheets moved to be dropped and the sheets conveyed from the conveying path without intervening the waiting tray, before carrying out the post-process. Sheet bundles formed on the processing tray are stacked on a storage tray by a sheet conveying mechanism after they have been post-processed. | 04-08-2010 |

20090057995 | IMAGE FORMING APPARATUS WITH PAPER THICKNESS DETECTION UNIT AND IMAGE FORMING METHOD OF THE SAME - An image forming apparatus of an embodiment of the invention includes a paper feed cassette to contain a sheet on which an image is to be printed, a pair of conveyance rollers to nip and convey the sheet taken out from the paper feed cassette, a paper thickness detection unit that is provided downstream of the sheet conveyed by the pair of conveyance rollers and near a nip point between the pair of conveyance rollers, has a rotator brought into contact with the sheet, and detects a thickness of the sheet by a shift generated when the sheet contacts with the rotator, a register roller to align the sheet after the thickness of the sheet is detected by the paper thickness detection unit, and a print ejection mechanism that prints and fixes an image to the sheet passing through the register roller and then ejects it. | 03-05-2009 |
20100300196 | IMAGE FORMING APPARATUS AND VIBRATION ISOLATOR SELECTION METHOD - An image forming apparatus includes a media sensor which a sheet carrying device has at a halfway part in a sheet carrying path, a damper table which stores a frequency band of vibration to be absorbed for each type of vibration isolator, and a controller which samples an output from the media sensor, performs Fourier transform on a waveform acquired as a result of the sampling, thus calculates a frequency, then searches the damper table on the basis of the resulting frequency, reads an optimum vibration isolator, and outputs the optimum vibration isolator to a control panel. | 12-02-2010 |
20110262151 | IMAGE FORMING APPARATUS, RECORDING MEDIUM DETECTING APPARATUS AND RECORDING MEDIUM DETECTING METHOD - An image forming apparatus according to an embodiment includes an image forming unit which forms an image on a recording medium, and a carrying unit which guides the recording medium to the image forming unit via a first carrying path or a second carrying path. A media sensor is arranged at a part where the first carrying path and the second carrying path merge together, to discriminate the type of the recording medium. The media sensor is movable toward the first carrying path or toward the second carrying path where the recording medium passes. | 10-27-2011 |
