A printing apparatus includes a printing unit that prints an image on a sheet by using ink, a feed path along which the sheet is transported toward the printing unit, a switchback mechanism that, when two sides of the sheet are to be printed, switches back the sheet of which one of the two sides has been printed and sends the sheet to the feed path, and a correction roller pair capable of correcting skew of the sheet by having firm contact with the sheet transported along the feed path. The correction roller pair includes a correction driving roller (61) and a correction driven roller that face each other and transports the sheet toward the printing unit as the correction driving roller (61) and the correction driven roller nip the sheet and rotate. The correction driving roller (61) has on its peripheral surface a plurality of protruded portions (77) capable of having point contact with the sheet and contacts the sheet from a side opposite, across the feed path, to a side on which the printing unit is provided.

A maintenance support system includes a terminal to be connected to one or more devices and one or more autonomous mobile bodies configured to acquire an own location, and transmits abnormality information from an abnormal device to the autonomous mobile body. The autonomous mobile body travels to a location of the abnormal device, based on the abnormality information.

A printing apparatus includes a carriage unit, and carries out printing on a recording medium while transporting the recording medium. The carriage unit includes a first head that discharges an ink and a second head that discharges an ink of the same color, and the second head is disposed so as to be adjacent to the first head in an x axis direction, and to overlap with the first head in a y axis direction. In an outgoing path in the reciprocation of the carriage unit, a printing density of a first image, which the first head prints, gradually decreases toward a downstream side in a transport direction of the recording medium, and the first image includes a dot group, in which at least two dots formed using the ink from the first nozzles are linked to one another in the x axis direction. In addition, in a return path in the reciprocation of the carriage unit, the second nozzles print a second image, which supplements a decrease in the printing density of the first image.

A correction table generation method includes acquiring a first color value of an apparatus non-dependent color system corresponding to an input value of a multi-dimensional apparatus dependent color system in an input lattice point of the color conversion table and generating a multi-dimensional conversion table in which a first apparatus dependent value of the apparatus dependent color system having color conversion table color value characteristics is correlated with a second apparatus dependent value having a color value of the apparatus non-dependent color system and approximate linearity over multiple dimensions, and the generating of the multi-dimensional conversion table includes determining a target color value for multiple dimensions having approximate linearity over the multiple dimensions with respect to the input value, and determining a first apparatus dependent value corresponding to a second apparatus dependent value using the input value, the target color value for the multiple dimensions, and the first color value.

A liquid ejecting apparatus includes: a supporting section capable of supporting a medium; an ejecting section capable of ejecting liquid onto the medium supported by the supporting section; and a first detecting section capable of detecting whether an amount of space between the medium supported by the supporting section and the ejecting section is equal to or more than a first threshold value. The liquid ejecting apparatus thus configured makes it possible to prevent liquid from being ejected from an ejecting section onto a medium in a state where an amount of space between the medium and the ejecting section is too large.

The present invention provides a photocurable ink composition for ink jet recording with excellent curability. The photocurable ink composition for ink jet recording includes polymerizable compounds, a photopolymerization initiator, and a colorant, wherein the polymerizable compounds include a vinyl ether group-containing (meth)acrylate represented by general formula (I): CH 2 =CR 1 -COOR 2 -O-CH=CH-R 3 (I) (wherein R 1 is a hydrogen atom or a methyl group, R 2 is a divalent organic residue having 2 to 20 carbon atoms, and R 3 is a hydrogen atom or a monovalent organic residue having 1 to 11 carbon atoms) and phenoxyethyl (meth)acrylate.

A fabric printing apparatus (100) includes a transport belt (23) configured to transport fabric (1) in a transport direction, a printing section (40) configured to perform printing by imparting ink droplets onto the fabric (1) having been transported, and a control section (80) configured to control positions for imparting the ink droplets, and based on displacement characteristic data indicating displacement amounts of the transport belt (23) that arise in a direction intersecting with the transport direction along with movements of the transport belt (23) in the transport direction, the control section (80) corrects the positions for imparting the ink droplets, in the direction intersecting with the transport direction.

Provided is a robot including a hand and a control unit that operates the hand. The control unit rotates a first object around a predetermined position of the first object with the hand and moves the first object with respect to a second object, based on a captured image including the hand and the first object. Therefore, the robot can perform good assembly work. The predetermined position may be a coordinate origin that moves with the first object, and the control unit may translate the first object in addition to rotating the first object. The robot may also include a force sensor that detects an external force acting on the hand.
