An ink jet recording apparatus including an ink jet head for ejecting and attaching a radiation-curable ink jet composition to a recording medium, an inert gas supply portion for supplying an inert gas to the recording medium to which the radiation-curable ink jet composition is attached, and an irradiation portion for applying radiation to the radiation-curable ink jet composition attached to the recording medium under supply of an inert gas, wherein the inert gas supply portion slantingly ejects the inert gas toward just under the irradiation portion.

A holding portion is held by a main body portion. The holding portion includes at least one recording head, a carriage, a cover portion, and a blowing unit. The recording head is capable of discharging ink. The carriage has a bottom wall portion to which at least one recording head is attached, and accommodates the at least one recording head. A cover portion has a facing surface facing the bottom wall portion. The blowing unit blows an air toward the facing surface so that the air reaches the recording head.

Holding unit and liquid discharge device

Included are a first orientation region in which a liquid crystal molecule is oriented along a first direction and a plurality of pixels are included; a second orientation region in which a liquid crystal molecule is oriented along a second direction intersecting the first direction and a plurality of pixels are included; a third orientation region in which a liquid crystal molecule is oriented along a third direction intersecting the second direction and opposite to the first direction and a plurality of pixels are included; and a fourth orientation region in which a liquid crystal molecule is oriented along a fourth direction intersecting the third direction and opposite to the second direction and a plurality of pixels are included.

Liquid crystal device comprising a plurality of orientation regions through which liquid crystal molecules are circulated and electronic device

A printing apparatus includes: a head portion that discharges droplets toward a printing medium while reciprocating on the printing medium; and a controller that controls movement of the head portion during a printing operation such that a movement stop time of the head portion when a movement direction of the head portion is reversed at an endmost portion of a range in which the head portion moves is longer than the movement stop time of the head portion when the movement direction of the head portion is reversed on the printing medium.

Printing apparatus

A printing apparatus includes: a platen that supports a printing medium; a head-portion that discharges droplets toward the printing medium while reciprocating on the printing medium; an interval-adjusting-mechanism that adjusts an interval between the platen and the head-portion; and a controller that controls the head-portion and the interval-adjusting-mechanism, in which the controller has a first printing mode in which printing is performed while the interval is set to a first interval and a second printing mode in which the printing is performed while the interval is set to a second interval that is larger than the first interval, as a printing mode in which the printing is performed on the printing medium. The controller controls movement of the head-portion such that a movement stop time of the head-portion when a movement direction of the head-portion is reversed is longer in the second printing mode than in the first printing mode.
