| 20090245869 | IMAGE FORMING APPARATUS, METHOD OF ALLOWING DRIVEN MEMBER TO BE MOUNTED ON APPARATUS BODY IN IMAGE FORMING APPARATUS AND METHOD OF ALLOWING DRIVE FORCE TO BE TRANSMITTED TO BELT UNIT IN IMAGE FORMING APPARATUS - The image forming apparatus includes: an apparatus body including a drive source; a driven member detachably attachable to the apparatus body; a first transmission member in the apparatus body, including a base rotatable around a rotation axis, and transmitting drive force from the drive source to the driven member; and a second transmission member in the driven member, including a base rotatable around the rotation axis, and transmitting drive force from the first transmission member to the driven member. Any of the first and second transmission members includes a projection, and the other includes a receiving port. The receiving port receives the projection when a rotation angle between the first and second transmission members is an angle set in advance while not receiving the projection when the rotation angle is out of the angle, at the time of mounting the driven member on the apparatus body. | 10-01-2009 |
| 20100092210 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an apparatus body that includes an image forming unit forming an image; a switching mechanism that switches a state of members between a contacting state and a non-contacting state, the members related to image formation by the image forming unit in the apparatus body; a covering unit that is supported in the apparatus body so as to be freely opened and closed, and that covers a part of the apparatus body when being closed; and a connection unit that is provided to the covering unit, that is not connected to the switching mechanism when the covering unit is opened while being connected to the switching member when the covering unit is closed, and that causes the switching mechanism to operate in conjunction with an operation by an operator any one of to open and to close the covering unit. | 04-15-2010 |

| 20100330262 | RECORDING 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 |
| 20110097127 | METHOD 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 |
| 20110122189 | RECORDING 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 |
| 20110132957 | RECORDING-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 |
| 20110135372 | BOTH-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 |

| 20100162985 | Recoil Starter - According to an aspect of the present invention, there is provided a recoil starter including: a case having a reel supporting shaft; a rope reel having: a tubular shaft portion; an engaging portion; a rope housing groove to house a recoil rope; and a spring housing portion to house a spiral spring; a ratchet axially-slidably arranged outside the tubular shaft portion; a ratchet guide attached to an end of the reel supporting shaft; and a return spring provided between the ratchet guide and the ratchet, wherein an inclined surface and a locking surface are formed on the engaging portion to be engageable with the ratchet, and wherein the inclined surface guides the ratchet toward to be engaged with the driving pulley, thereby rotating the driving pulley and starting the engine, when the rope reel is rotated. | 07-01-2010 |
| 20100206259 | Recoil Starter - According to an aspect of the present invention, there is provided a recoil starter including: a case; a reel pivot formed on the case; a rope reel rotatably supported on the reel pivot; a recoil spring; a cam; a power storage spring interposed between the rope reel and the cam; and a power storage ratchet mechanism disposed between facing surfaces of the rope reel and the cam and. The power storage ratchet mechanism is configured to disengage the rope reel and the cam when the rope reel rotates in an engine-starting direction, and engage the rope reel and the cam when the rope reel rotates in an opposite direction to the engine-starting direction. | 08-19-2010 |
| 20110048361 | Recoil Starter - One of the embodiments provides a starter including: a starter case; a rotational torque applying unit; a torque-accumulation spring; a rotating member; a driving pulley; and a rotation regulating mechanism including: a regulating ratchet provided on the driving pulley or the rotating member at a position shifted from a rotation center thereof; and a pressing unit provided on the starter case and urged by a given resilient pressing force to be engaged with the regulating ratchet, wherein, when the rotational torque accumulated in the torque-accumulation spring exceeds the given resilient pressing force, the driving pulley or the rotating member urges back the pressing unit via the regulating ratchet so that the regulating ratchet is disengaged from the pressing unit, to thereby release the rotational torque. | 03-03-2011 |
