A recording apparatus includes a recording head that performs recording; a feeding roller that feeds out a medium that has been set, a transport roller that transports the medium fed out by the feeding roller toward a facing position facing the recording head; an auxiliary roller that is provided between the feeding roller and the transport roller and that assists in the transport of the medium; a motor that generates a driving force; and a drive train that is configured to transmit the driving force of the motor to the auxiliary roller and the transport roller.

An image forming apparatus includes a moving unit and a lifting and lowering mechanism. The moving unit is supported by a casing in an upwardly and downwardly moving manner. A fixed pully and a winding pully are provided in the casing. A movable pulley is provided in the moving unit. A wire is configured to be wound around the fixed pulley and the movable pulley. One end of the wire is fixed to the casing and the other end of the wire is fixed to the winding pulley. A rack is provided in the casing along an upper-and-lower direction. A pinion is provided in the moving unit and configured to be engaged with the rack. The winding pulley is rotated to wind and unwind the wire via the fixed pulley and the movable pulley, and the moving unit is lifted and lowered while the pinion being engaged with the rack.

An image forming apparatus includes a head unit, a conveyance unit, a lifting and lowering mechanism, a drive source and a transmission mechanism. The head unit is provided with an inkjet head having a discharge opening through which an ink is discharged. The conveyance unit is supported in an upwardly and downwardly movable manner in directions close to and apart from the head unit from a lower side. The lifting and lowering mechanism is configured to lift and lower the conveyance unit. The drive source is configured to drive the lifting and lowering mechanism. The transmission mechanism is configured to transmit driving force from the drive source to the lifting and lowering mechanism. The transmission mechanism includes a warm gear, a warm wheel meshed with the warm gear and a resistance applying member configured to apply resistance to rotation of the warm gear.

An image forming apparatus may include a mechanism for forming a corrugated shape in a sheet to be conveyed. The mechanism may include various components include one or more pressing portions, one or more ribs, one or more discharge rollers, a switching mechanism and the like. In one arrangement, ribs and pressing portions configured to create the corrugated shape may be disposed at various locations upstream or downstream of the platen, recording portion and/or nozzles thereof. In one example, pressing portions may be disposed both upstream and downstream of the nozzles of the recording portion to maintain a corrugated shape in the conveyed sheet. Various other configurations may be used.

A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
