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 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.

摘要： A supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette towards a sheet guide and a pair of feed-in rollers for sending the piece of sheet supplied from the sheet guide towards a printing region are provided within a printer. The pair of feed-in rollers has a feed-in drive roller driven by a motor and a feed-in driven roller driven by the feed-in drive roller. A sending speed of the pair of feed-in rollers is faster than a sending speed of the supply roller, and a sending force of the pair of feed-in rollers is stronger than a sending force of the supply roller. A controller of the printer controls the rotation of the supply roller and the pair of feed-in rollers according to a procedure that does not rely on a position of the sheet sent by the supply roller and the pair of feed-in rollers during the continuous feeding mode.

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： A sheet feeding apparatus includes a switchable transmission mechanism disposed between a pickup roller and a driving source, and switches the driving source between a first state for rotating in the forward direction to rotate the pickup roller, and a second state for not rotating the pickup roller, the forward direction is opposite to a direction in which the driving source is rotated to rotate a feeder roller in a sheet feed direction. The sheet feeding apparatus also includes a control portion rotating the driving source in the forward direction to rotate the pickup roller in a sheet supply direction, and switches the switchable transmission mechanism between the first state, when a sheet is supplied from a sheet holding portion, and the second state, when the sheet is fed by the feeder roller.

摘要： An image forming apparatus includes a sheet feed tray for loading a recording sheet, a sheet feed roller that conveys the recording sheet toward an image forming device, a conveyor roller that is disposed downstream of the sheet feed roller in a recording sheet conveying direction and that applies a conveying force on the recording sheet, a sheet position detection device that detects a position of the recording sheet in a conveying path, and a conveyor roller control device that controls a rotation amount of the conveyor roller in accordance with the detected position of the recording sheet. The control device allows the rotation amount of the conveyor roller to become greater, when a recording sheet contacts the sheet feed roller and the conveyor roller, than a rotation amount of the conveyor roller when the recording sheet contacts the conveyor roller but might not contact the sheet feed roller.
