摘要： A printer has a carriage being movable between a first end and a second end of a reciprocating path; and a driving force transmitting path selecting mechanism provided at the second end of the reciprocating path. The selecting mechanism has: a common driving force outputting member; a plurality of force receiving members; a selecting member; and a position retainer for keeping the position of the selecting member. The selecting member connects the force outputting member to one of the plurality of force receiving members, and moves in association with the carriage when the carriage moves in a vicinity of the second end in a first direction extending from the first end to the second end. The position retainer keeps the position of the selecting member when the carriage moves in a second direction extending from the second end to the first end. The force receiving member connected to the force outputting member via the selecting member is selected in accordance with a movement of the carriage along the reciprocating path.

摘要： In an image-recording device, a feeding roller feeds recording media one at a time from a media-accommodating unit along a conveying path. A pair of registration rollers is disposed on the conveying path and conveys the recording medium fed by the feeding roller to an image-recording region. The registration rollers include a drive roller. A carriage reciprocates in the image-recoding region in a direction intersecting a conveying direction in which the recording medium is conveyed. A recording head is mounted on the carriage. A drive transmission switching unit is disposed outside the image-recording region on one end with respect to the reciprocating direction of the carriage and switches a combination of rotating and halted states of the drive roller in the registration rollers and the feeding roller between a continuous feeding mode and an intermittent feeding mode. A controlling unit activates the drive transmission switching unit by moving the carriage to selectively switch between the continuous feeding mode and the intermittent feeding mode.

摘要： A method for feeding a recording medium includes the steps of: feeding the recording medium along a sheet-feeding path by a unit feeding amount, detecting an entrance of a rear end of the recording medium into a jumping alarm area, dividing the unit feeding amount into minute divisional feeding amounts such that the recording medium is fed by each minute divisional feeding amount when the rear end of the recording medium enters the jumping alarm area, detecting a jumping amount of the recording medium corresponding to a rotation of a driving roller when a jumping phenomenon occurs in the recording medium, and adjusting the minute divisional feeding amount to cancel the jumping amount.

摘要： A printer is equipped with a supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette; a pair of feed-in rollers for sending the piece of sheet supplied from the supply roller toward a printing region; and a sheet sensor provided between the supply roller and the pair of feed-in roller. The printer rotates the pair of feed-in rollers in a forward direction in a case that the sheet sensor detects presence of the sheet at a timing when it is found that printing data for a subsequent sheet is not stored within the printer. On the other hand, the printer rotates the supply roller in a reward direction when the sheet sensor detects non-presence of the sheet at the timing when it is found that the printing data for the subsequent sheet is not stored within the printer.
