A medium support portion including a support face that supports a medium, a heater configured to heat a surface of the medium remotely from the support face, an airflow supply unit configured to supply airflow, along the surface of the medium, to a region between the medium and the heater, a plurality of heater support portions that support the heater, and at least one first temperature detection unit located remotely from the support face and configured to detect a spatial temperature in the region that is in contact with the surface of the medium are provided, in which the at least one first temperature detection unit is disposed between two mutually adjacent heater support portions among the plurality of heater support portions.

Heating device and recording apparatus

A printing apparatus includes a transporting unit that transports a printing medium, a transporting unit encoder that outputs a movement amount information indicating a movement amount of the printing medium, a medium winding unit disposed downstream of the guide member with respect to the transporting unit and winds the printing medium, a tension applying unit including a tension bar that presses the printing medium at a location between the transporting unit and the medium winding unit while the tension bar is moving between an upper limit position and a lower limit position and applies tension to the printing medium, a tension applying unit encoder that outputs a rod member location information indicating a position of the tension bar, and a control unit that determines a movement state of the printing medium at the tension applying unit, based on the movement amount information and the rod member location information.

Printing apparatus and printing method

A medium feeding apparatus includes a roll motor which applies torque for rotating a roll body to the roll body, a storage portion which stores output measured value, which is measurement result of output value to the roll motor for rotating the roll body, and a roll control portion which corrects the output measured values stored in the storage portion to correction value in accordance with stop time of the roll motor, and controls the roll motor based on the corrected output measured values.

Medium feeding apparatus

A medium feeding apparatus includes a roll holding portion which holds a roll body around which a printing medium is wound, a feeding roller which pulls out the printing medium from the roll body and feeds the printing medium, a roll motor which rotates the roll body held by the roll holding portion, a roll motor control portion which controls the roll motor, and rotation position detecting portions which detect a rotation position of the roll body, the roll motor control portion performs removing looseness of the printing medium pulled out from the roll body by driving the roll motor and rotating the roll body in a rewinding direction, and in the removing, driving of the roll motor is finished on the basis of movement of the rotation position detected by the rotation position detecting portions.

Medium feeding apparatus, printing apparatus, and control method of medium feeding apparatus

A liquid discharging apparatus includes a feeding unit that feeds a medium, a feeding driving unit that drives the feeding unit, a liquid discharging unit that performs a discharging operation of discharging a liquid to the medium, and a controller that controls the feeding driving unit to start to operate in synchronization with a timing when the liquid discharging unit finally discharges the liquid in the discharging operation.

Liquid discharging apparatus

Ratchets which regulate a rotation of either a reeling-out roller around which one end of a long wiping member which wipes ink attached to a recording head which ejects ink is wound, or a winding-up roller around which the other end of the wiping member is wound to which tension is applied due to a friction force which acts on the wiping member when performing wiping are provided.

Wiper cassette, wiper unit and liquid ejecting apparatus

To press a medium using an appropriate pressing force and perform colorimetric measurement, a color measurement device for performing colorimetric measurement of a print pattern printed on a medium, the color measurement device comprising a pressing member for pressing the medium; a power source for outputting power for the pressing member to press the medium; a detecting part for detecting a pressing force on the medium; a color measurement section for performing colorimetric measurement of the print pattern; and a control part for controlling the power source so that the pressing force detected by the detecting part is equal to a predetermined pressing force, and for causing the color measurement section to perform colorimetric measurement of the print pattern printed on the medium pressed by the pressing member.
