An inkjet recording apparatus may include a corrugate mechanism configured to form a sheet into a corrugated shape. The inkjet recording apparatus may be configured to receive sheets of various sizes and shapes. Accordingly, in some examples, the inkjet recording apparatus may include differently configured portions to handle sheets of different sizes or shapes. According to one arrangement, the inkjet recording apparatus may be configured to receive passage of sheets of a first size through multiple ones of the differently configured portions while receiving passage of sheets of a second size though limited ones of the differently configured portions.

An image recording device may include corrugate mechanisms to prevent undesired bending and jamming of a recording sheet. In some examples, the image recording device may include a first corrugate mechanism, a second corrugate mechanism and a third corrugate mechanism. The first, second and third corrugate mechanisms may be configured to create a corrugated shape in a recording sheet. The second and third corrugate mechanisms, in one or more arrangements, may be located downstream of the first corrugate mechanism and an ink nozzle. The third corrugate mechanism may further be configured such that no upper contact portion thereof may be disposed at a same position, with respect to the width direction, as endmost upper contact portions of the first corrugate mechanism with respect to the width direction. In yet other examples, the third corrugate mechanism may be located downstream of a reverse sheet conveying path.

There is provided an ink-jet recording apparatus including: a first transporting portion provided in a first transport path; a support member configured to support the sheet; a recording portion; a plurality of contact portions configured to come into contact with the sheet; a plurality of support ribs; a second transporting portion provided in a second transport path connected with the first transport path; and a third transporting portion configured to sandwich and transport the sheet in the first transporting direction or toward the second transport path. On the upstream side to the second transporting portion in the second transporting direction, a projecting portion is formed with the upper guide member to project toward the lower guide member below a virtual line linking a nip position of the sheet due to the third transporting portion with another nip position of the sheet due to the second transporting portion.
