A conveyor includes a conveyance roller to convey a conveyed object, a pair of roller supports opposing to each other and supporting both ends of the conveyance roller in an axial direction thereof, a position sensor to detect a position of the conveyed object, and a sensor support supporting the position sensor. Each of the pair of roller supports has an insertion hole into which the sensor support is inserted. The insertion hole determines a position of the sensor support in a direction intersecting an insertion direction of the sensor support. The sensor support includes a positioning portion determining the position of the sensor support with respect to at least one of the pair of roller supports. The positioning portion determines the position of the sensor support in the insertion direction, a direction opposite to the insertion direction, and a rotational direction about an axis along the insertion direction.

A liquid discharge apparatus to discharge liquid to apply the liquid to an object includes a head, a mover, a rotator, and processing circuitry. The head has a nozzle surface in which a plurality of nozzle rows each including a plurality of nozzles to discharge the liquid are arranged. The mover relatively moves the head and the object in each of a first direction and a second direction orthogonal to each other along the nozzle surface. The rotator rotates the head along the nozzle surface. The processing circuitry controls the relative movement to correct unevenness of a nozzle interval between the plurality of nozzles along the second direction caused by an inclination between the first direction and a third direction when the head is rotated. The third direction is a direction in which the plurality of nozzles are arranged in each of the plurality of nozzle rows.

According to an embodiment of the present disclosure, a plurality of functions may be performed with a single device, to maximize work efficiency in time and space, and reduce costs.

A liquid ejection apparatus includes a medium container, a liquid ejection head, a mover, and a controller. The mover is configured to execute, among a first moving operation of moving a sheet-like medium and a second moving operation of moving the liquid ejection head, at least the first moving operation. The controller causes the liquid ejection head and the mover to alternately or simultaneously perform execution of the first moving operation and execution of ejection and second moving operations, and adjusts at least one selected from the group of an amount of liquid to be ejected, a time interval between the ejection operations when alternately performing execution of the first moving operation and execution of the ejection and second moving operations, and a moving speed of the medium when simultaneously executing the ejection operation and the first moving operation, according to medium information relating to curling of the medium.

There is provided a recording device including a transport section that transports paper along a support surface; a recording section; a determination region setting section; a liquid volume ratio calculation section; a determination section; and a recording position adjustment section that, when the determination section determines that the average value is larger than the threshold, adjusts a distance of the recording section from the support surface to a distance which is longer than a case in which the average value is not larger than the threshold.

An inkjet recording device includes: an inkjet head that includes a nozzle for discharging ink on a recording material, and forms an image by discharging the ink from the nozzle on the recording material based on image data; and a hardware processor that performs image processing of the image data, wherein the hardware processor calculates a difference in ink adhesion amount between a target region and an adjacent target region adjacent to the target region in the image data, determines whether the difference in the ink adhesion amount exceeds a threshold based on a calculation result of the hardware processor, and performs a responding process for occurrence of a wrinkle on the recording material based on a determination result of the hardware processor.

Provided is a three-dimensional object printing apparatus, in which a printing operation for a workpiece includes: a first pass in which liquid is ejected toward a first region of the workpiece; a second pass in which the liquid is ejected toward a second region that partially overlaps the first region of the workpiece; a third pass in which the liquid is ejected toward a third region of the workpiece; a fourth pass in which the liquid is ejected toward a fourth region that partially overlaps the third region of the workpiece, the curvature of a surface including the first region and the second region is larger than the curvature of a surface including the third region and the fourth region, and an overlapping width between the first region and the second region is smaller than an overlapping width between the third region and the fourth region.
