Patent application numberDescriptionPublished
20100330262RECORDING APPARATUS AND SHEET PROCESSING METHOD - A method includes pulling out and conveying a sheet having splice portions, acquiring information relating to a position of an indentation on the sheet formed in addition to a splice portion, and performing processing on the sheet but a position corresponding to the acquired position of the indentation and its vicinity.12-30-2010
20110097127METHOD OF CORRECTING CURL OF SHEET AND RECORDING APPARATUS - In a first step, a sheet is conveyed in a direction, whereby a leading end portion of the sheet is fed to a position between a decurl roller and a decurl pinch roller, which are in positions spaced apart from each other. In a second step, the leading end portion of the sheet is curved and held by causing the decurl pinch roller to come close to or press against the decurl roller. In a third step, the leading end portion of the sheet is withdrawn from between the decurl roller and the decurl pinch roller by conveying the sheet in a direction opposed to the conveying direction. After executing the first to third steps, the sheet is conveyed in the conveying direction through the first step while the sheet is curved by the decurl roller.04-28-2011
20110122189RECORDING APPARATUS - An apparatus includes a line-type recording head including a plurality of recording elements formed thereon, a holding unit configured to hold a sheet, a conveyance mechanism configured to convey the sheet held by the holding unit to a position of recording by the recording head, a shift mechanism capable of relatively shifting a position of the sheet in a sheet width direction with respect to the recording head while the sheet is fed from the holding unit to the recording position, and a control unit configured to control the conveyance mechanism and the shift mechanism.05-26-2011
20110132957RECORDING-MEDIUM-CONVEYING DEVICE AND RECORDING APPARATUS - A device includes a conveying roller configured to convey a recording medium, a follower roller configured to press the recording medium against the conveying roller, a detector configured to detect a direction of skew of the conveyed recording medium, and a changer configured to change a state of contact between the recording medium and the conveying roller in accordance with a result of the detection by the detector such that a length of a portion of the conveying roller that is in contact with the recording medium in a conveyance direction is larger on a side toward which the recording medium is skewed than on an opposite side.06-09-2011
20110135372BOTH-SIDE RECORDING APPARATUS - A both-side recording apparatus that enables both-side recording on continuous paper using a single recording head, without cutting the continuous paper at an intermediate position, is provided. Reduction in size and costs of the apparatus is achieved by eliminating a conveying path dedicated to both-side recording. The apparatus includes a paper-feeder that feeds continuous paper, a recording head that records an image on the continuous paper, a reversing unit that reverses the continuous paper such that a recording surface of the continuous paper facing the recording head is reversed, and a rewinding mechanism that rewinds the fed continuous paper to the paper-feeder. During both-side recording, recording is performed on the back side of the continuous paper by rewinding the continuous paper by the rewinding mechanism, setting the back side of the continuous paper to oppose the recording head by the reversing unit, and feeding the continuous paper from the paper-feeder.06-09-2011
20110211896PRINTING APPARATUS - An apparatus may include a print head, multiple roller pairs to convey a sheet, a direct sensor, and a control unit. The print head prints on a conveyed sheet. The multiple roller pairs nip the sheet at an upstream side of the print head to convey the sheet, nip the sheet at a downstream side of the print head, and nip the sheet at an upstream side of a first roller pair to convey the sheet. The direct sensor measures a surface of the conveyed sheet at a measurement position between a nip position of the first roller pair and a nip position of a third roller pair to obtain information relating to a movement state of the sheet. The control unit controls to correct at least one of driving control of the print head and conveying control of the sheet, based on the information obtained by the direct sensor.09-01-2011
20110266742SHEET CONVEYANCE APPARATUS AND RECORDING APPARATUS - An apparatus includes a first conveyance unit configured to convey a sheet, a first guide located downstream of the first conveyance unit in a conveyance direction and configured to guide a first side end of the conveyed sheet, a skew unit configured to convey the sheet in an oblique direction to come closer to the first guide, a second guide configured to contact a second side end opposite the first side end to guide the second side end, a second conveyance unit located downstream of the first guide in the conveyance direction, and a control unit configured to perform control so that, after conveying the sheet by the skew unit with the first guide contacting the first side end while the second guide is separated from the second side end, the second guide moves to a position close to the second side end.11-03-2011
20110279510PRINTING APPARATUS - An apparatus includes an adjusting mechanism configured to change a gap between a print head and a continuous sheet, and the adjusting mechanism controls the gap to be larger than that at the time of printing when a splice of the continuous sheet passes the print head. An unprintable area is set on each of the upstream side and the downstream side of the splice, each having at least a width corresponding to a sum of a length of the plurality of print heads in the direction of sheet conveyance and a distance of movement of the continuous sheet in a period required for the adjusting mechanism to change the gap, and the printing is continued while avoiding the unprintable area.11-17-2011
20110280642PRINTING APPARATUS - A control unit includes a memory storing correction data obtained by associating information acquired by a first acquisition unit (rotary encoder) with information acquired by a second acquisition unit (direct sensor) with respect to, at least one rotation of a conveying roller. When a plurality of images are sequentially printed on a first surface and a second surface of a continuous sheet, the control unit reads the correction data corresponding to the rotation information acquired by the first acquisition unit from the memory and corrects at least one of driving control of a print head and driving control of the roller. The correction data used in printing on the first surface of the sheet is different from that used in printing on the second surface of the sheet.11-17-2011
