摘要： A sheet conveying device includes a feed tray including a bottom plate configured to hold a sheet, a feed roller configured to feed the sheet in a first direction from the feed tray to a first conveying path, and a pressing member configured to press the sheet in the feed tray against the bottom plate of the feed tray. The pressing member includes a contact portion configured to contact the sheet in the feed tray, and a first guide positioned at a downstream end of the pressing member in the first direction. The first guide extends between the downstream end and the contact portion obliquely with respect to the bottom plate, such that a distance between the bottom plate and the first guide increases along the first direction. The first guide is positioned upstream of the feed roller in the first direction.

摘要： A first convey roller conveys a sheet in a sheet conveying direction such that a leading edge of the sheet passes through a nip of a second convey roller disposed downstream from the first convey roller. The second convey roller rotates in a reverse direction by a first rotation amount corresponding to a first linear distance to convey the sheet in a direction opposite to the sheet conveying direction, such that the leading edge of the sheet is released from the nip of the second convey roller. In response to the rotation of the second convey roller in the reverse direction, the first convey roller rotates by a second rotation amount corresponding to a second linear distance in the reverse direction to convey the sheet in the direction opposite to the sheet conveying direction, such that the leading edge of the sheet contacts the nip of the second convey roller when the first convey roller has rotated by the second rotation amount and the second convey roller has rotated by the first rotation amount.

摘要： In an image recording apparatus according to an aspect of the invention, a recording medium is allowed to be conveyed on a conveying path. An inversion guide portion connects a first portion of the conveying path positioned downstream of a recording unit to a second portion of the conveying path positioned upstream of the recording unit. A path changeover unit is disposed at the first portion of the conveying path and swingable between a recording medium discharge position and a recording medium inversion position. When the path changeover unit is positioned at the recording medium discharge position, the forward rotation of the roller pair allows the recording medium to be sent to a discharge portion. When the path changeover unit is positioned at the recording medium inversion position, the rearward rotation of the roller pair allows the recording medium to be sent to the inversion guide portion.
