A box forming machine includes a converter assembly, a fold assembly, and an attachment assembly. The converter assembly converts sheet material into a box template. The fold assembly engages a first end of the box template and moves the first end of the box template to a predetermined position. The attachment assembly engages a second end of the box template and moves the second end of the box template toward and into engagement with the first end of the box template to attach the first and second ends of the box template together.

An image recording apparatus is configured to perform a conveying process of a recording medium using a conveying roller and a discharging roller, a recoding process of recording an image on the printing sheet when the conveying process is not performed, and an adjusting process. In the adjusting process, among a plurality of conveying processes performed within a period from the start of the conveying process for an n-th printing sheet until the timing which is after the start of the conveying process for an (n+1)-th printing sheet, the conveying amount of the printing sheet subject to at least one conveying process is adjusted such that a timing when the trailing end of the n-th printing sheet passes through the discharging roller is within one of the acceleration period and the deceleration period of the conveying process for the printing sheet.

A controller determines whether, in a case where feeding of a subsequent sheet is performed in a first feed condition, a subsequent sheet contacts conveyance rollers during recording on a preceding sheet, the first feed condition being that feeding of the subsequent sheet is started at a first timing before recording on the preceding sheet ends and that the subsequent sheet is fed at a first velocity, and in response to determining that the subsequent sheet contacts the conveyance rollers during recording on the preceding sheet, controls the feed roller to perform feeding of the subsequent sheet in a second feed condition or a third feed condition, the second feed condition being that the feeding of the subsequent sheet is started at a second timing later than the first timing, the third feed condition being that the subsequent sheet is fed at a second velocity lower than the first velocity.

A sheet conveying device includes a conveying roller configured to convey a sheet and a plurality of driven rotating units. The conveying roller includes a plurality of roller portions disposed at positions opposite to the driven rotating units. Each of the roller portions has three or more annular grooves arranged side by side. Each of the driven rotating units includes three or more driven rotating bodies that are disposed at positions opposite to the annular grooves, respectively. A plurality of convex portions and a plurality of concave portions are alternately provided on an outer edge of each of the driven rotating bodies. The driven rotating bodies include two first rotating bodies positioned at both ends and one or more second rotating bodies located between the first rotating bodies and having an outer diameter smaller than the outer diameter of the first rotating bodies.

A printer includes a driving roller to move a medium supported on a support table in a predetermined transportation direction, and pinch roller assemblies each including a pinch roller, a support to support the pinch roller to allow the pinch roller to contact, or to be spaced from, the driving roller, and an actuator provided upstream in the transportation direction with respect to the pinch roller. The actuator includes a contact portion contactable with the support, and an operation portion to press the contact portion to the support to move the pinch roller in a direction away from the driving roller.
