摘要： A printer for feeding the sheet intermittently with high precision while preventing a decrease in the print rate is provided. A printer has a feed-in roller for feeding a sheet into a printing region, a feed-out roller for feeding the sheet out of the printing region, a motor for rotating the feed-in roller and the feed-out roller, and a controller for controlling the motor. The controller controls the motor so as to start intermittent sheet feed with a first line-feed-time that specifies a time period for one line feed and vary the first line-feed-time to a second line-feed-time that is longer than the first line-feed-time before the sheet is fed by only the feed-out roller. The sheet is fed intermittently with a shorter line-feed-time while being fed by the feed-in roller which is precisely controlled. On the other hand, the sheet is fed intermittently with a longer line-feed-time while being fed by the feed-out roller which is not controlled as precisely as the feed-in roller. Hereby, the printer can feed the sheet intermittently with high precision while preventing a decrease in the print rate.

摘要： A conveying device of an image recording apparatus includes a drive roller, a follow roller, an urging member, a bearing member, a pivoting support member, and a driving unit. The urging member applies pressure to the follow roller for pressing the follow roller against the drive roller. The bearing member supports the urging member and rotatably supports the follow roller. The pivoting support member supports the bearing member such that the bearing member is pivotally movable about either one of a rotational axis of the drive roller and another axis different from the rotational axis. The driving unit pivotally moves the pivoting support member and the bearing member between a first position at which the follow roller is located on a conveying path for conveying a recording medium and a second position at which the follow roller is retracted from the conveying path.

摘要： An image forming apparatus includes a reading mechanism having an original placement portion, a recording mechanism having a medium supply tray and a reversing mechanism, a casing that houses the recording mechanism, and an operating section through which the image forming apparatus is manipulated. A longitudinal direction of the original placement portion is substantially parallel with a width direction of the casing and the operating section is disposed on a front side of the reading mechanism. A longitudinal direction of the medium supply tray is substantially parallel with a depth direction that is perpendicular to the width direction of the casing. The reversing mechanism is disposed close to a rear end side in the depth direction. A dimension of the recording mechanism in the depth direction is not more than a sum of a depth of the reading mechanism plus a depth of the operating section.

摘要： A feeding device including: (a) a feed mechanism including a motor driven with supply of a power thereto, and a feeder operated by the motor for feeding an object; (b) a power supply controller for supplying the power to the motor until an actual operating position of the feeder coincides with a power-supply-stop operating position located before a target operating position of the feeder, and to stop the supply of the power to the motor when the actual operating position coincides with the power-supply-stop operating position, for causing the actual operating position to eventually coincide with the target operating position owing to an inertia of the feed mechanism; and (c) a power-supply-stop operating-position determiner for determining the power-supply-stop operating position, for reducing a positioning error of the object in presence of a torque fluctuation of the feed mechanism, based on the target operating position and a cyclic variation of an operating velocity of the feeder that is caused by the torque fluctuation.
