An inkjet recording apparatus includes a feeding-side motor, an inkjet recording unit, a winding-side motor, a feeding-side roll-diameter measuring unit, a winding-side roll-diameter measuring unit, and a motor drive controller. Based on a relationship between motor rotating speeds and roll diameters under conveyance of the recording medium at a specified conveyance speed, the motor drive controller determines a first rotating speed corresponding to a feeding-side roll diameter measured by the feeding-side roll-diameter measuring unit and moreover determines a second rotating speed corresponding to a winding-side roll diameter measured by the winding-side roll-diameter measuring unit to drive the feeding-side motor at the first rotating speed and moreover drive the winding-side motor at the second rotating speed.

There is provided a printing apparatus that is capable of reducing an occurrence of transport disorder of a medium when transporting the medium unwound from an unwinding unit that holds a roll body.

The printing apparatus performs printing on the medium unwound from the roll body having the medium wound into a cylindrical shape, the printing apparatus including: an unwinding unit 40 that rotatably holds the roll body and unwinds the medium by rotating the roll body; a transport unit that transports the medium unwound from the unwinding unit 40; and a printing unit that performs printing on the medium transported by the transport unit. The unwinding unit 40 includes a first rotary body 441 that is integrally rotatable with the roll body by engaging with a first end of the roll body, a second rotary body 451 that is integrally rotatable with the roll body by engaging with a second end of the roll body, a first motor 442 that rotatably drives the first rotary body 441, and a second motor 452 that rotatably drives the second rotary body 451.

A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.

An apparatus to launch, retrieve, and store a recreational floating mat is described. The apparatus can provide the advantages of helping to ease the potential difficulties associated with launching, retrieving and storing recreational floating mats from dock side, pool side or from a floating vessel such as a boat or floating dock.
