Abstract: An image recording apparatus includes: a housing having a sheet conveyance path having curved and extending portions; and a pivotable guide member at least partly defining the curved portion and pivotable. The guide member has a first guide portion and a second guide portion pivotably coupled to it. The first guide portion is pivotable between a first position for partly defining the curved portion and a second position where the curved portion is open. The second guide portion is movable between a third position where the second guide portion partly defines the curved portion with the first guide portion located at the first position and a fourth position where the second guide portion extends in a direction from an inner side to the outer side of the curved portion with the first guide portion located at the second position.

Abstract: A first actuator is detected at a first detection position by a detecting unit when no sheet is held on a feed tray, and is not detected at a first non-detection position by the detecting unit when the first actuator is in contact with a sheet held on the feed tray. A second actuator is detected at a second detection position by the detecting unit when the second actuator is in contact, at a predetermined position downstream of the first actuator in a conveying direction, with a sheet conveyed, and is not detected at a second non-detection position by the detecting unit when the second actuator is out of contact, at the predetermined position, with the sheet conveyed. A restricting member restricts the first actuator from moving from the first non-detection position to the first detection position when the second actuator is at the second detection position.
