Abstract: A sheet-feeding device includes: a first feeding roller configured to contact a sheet accommodated in a sheet-accommodation portion to feed the sheet; a second feeding roller movable between a non-feeding position and a feeding position; a driving source configured to generate a rotational driving force to the first feeding roller; a transmission portion configured to transmit the rotational driving force to the second feeding roller; a first sensor; a second sensor; and a roller actuating portion. The roller actuating portion is configured to: move the second feeding roller from the non-feeding position to the feeding position in a case where the second detector detects rotation of the first feeding roller is stopped during a sheet-feeding operation; and move the second feeding roller from the feeding position to the non-feeding position in a case where the first sensor detects the sheet-feeding operation is completed for the sheet.

Abstract: An ink-jet recording apparatus includes: an image recorder; a first supporter including support ribs extending to positions under the image recorder; an ink receiver disposed downstream of the support ribs; first and second roller pairs disposed downstream of the first supporter; a guide; and a protrusion disposed between the ink receiver and the first roller pair and having an upper end located below upper ends of the support ribs and above a first imaginary line connecting between a nip position of the first roller pair and a downstream end of the ink receiver. A distance between an upstream end of the ink receiver and a nip position of the second roller pair is less than a length of a first-size sheet and greater than a length of a second-size sheet. The protrusion is disposed, in a widthwise direction, in a region through which the second-size sheet is conveyed.

Abstract: An image recording apparatus includes first and second conveying passages, a recording portion for recording images, first and second conveying rollers, first and second motors, a power transmission mechanism switchable between a first state and a second state, and a controller. In the first state of the mechanism, the controller drives the first motor to rotate the first and second conveying rollers, thereby conveying a recording medium along the first conveying passage in a first conveying direction. During this conveyance, the controller controls the recording portion to record an image on one surface of the recording medium. Then, the controller switches the mechanism from the first state to the second state, and drives the second motor in the second state of the mechanism to rotate the second conveying roller independently of the first conveying roller, thereby conveying the recording medium along the second conveying passage in a second conveying direction.

Abstract: An ink-jet recording apparatus includes: a roller; a first supporting member; a recording section; a second supporting member; and a first waved-shape imparting mechanism configured to impart, to the sheet, the waved shape so that both end portions of the sheet in the width direction are oriented downward. An upstream end portion, of the second supporting surface, in the conveyance direction is located below a downstream end portion of a first supporting surface of the first supporting member in the conveyance direction. The second supporting surface of the second supporting member is formed with projections arranged respectively at locations, of the second supporting surface, at which the both end portions of the sheet in the width direction are supported, the projections projecting upward above a location of the second supporting surface at which a central portion of the sheet in the width direction is supported.
