An embroidery device includes a needle including a hole through which a thread has been passed, a dyeing unit configured to dye the thread in different colors, an embroidery unit configured to move the needle to perform a sewing process on a medium with the thread dyed in the different colors by the dyeing unit, and a remover configured to remove the linear member in a vicinity of the needle.

A liquid discharge apparatus includes heads to discharge a liquid; caps to contact and move away from the plurality of heads, respectively; individual drain passages communicating with the plurality of caps, respectively; at least one common drain passage communicating with at least two of the individual drain passages; suction devices provided in the individual drain passages, respectively; and a controller. Each of the individual drain passages is to allow and shut off communication between the cap and the common drain passage. The controller causes the individual drain passage to allow the communication between the cap and the common drain passage when performing capping and decapping of the head. The controller caps the sucking target with the cap after shutting off each individual drain passage communicating with the cap corresponding to the head that is not a sucking target.

An embroidery system includes a coloring device to color a thread. The embroidery system includes an embroidery device to perform embroidery of an embroidery design and underlay stitching. The embroidery device uses the thread colored by the coloring device for at least one of the embroidery of the embroidery design or the underlay stitching. The embroidery system includes circuitry to: create data of the embroidery design and the underlay stitching according to embroidery image data; create color data for coloring the thread to be used for coloring the at least one of the embroidery of the embroidery design or the underlay stitching; acquire roughness data representing roughness impression of the embroidery image data; and change an embroidery density of the embroidery design according to the roughness data.

A liquid ejecting apparatus includes a plurality of ejection heads, each including a nozzle array in which a plurality of nozzles, each configured to eject a droplet, are arranged in an array; and an ejection receiver configured to receive the droplet from the plurality of ejection heads. A conveying direction in which an ejection target medium is conveyed and an arrangement direction in which the nozzle array is arranged are parallel to each other, and at a predetermined timing, at least one ejection head among the plurality of ejection heads moves to a position facing the ejection target medium and ejects the droplet toward the ejection target medium, and, simultaneously, a remaining ejection head among the plurality of ejection heads other than the at least one ejection head moves to be withdrawn from the position facing the ejection target medium and ejects the droplet toward the ejection receiver.

A liquid discharge apparatus includes a discharge head having a nozzle row, a conveyor is configured to convey a discharge target medium, a head mover configured to move the discharge head in an orthogonal direction, a head rotator configured to rotate the discharge head, and circuitry configured to perform a position setting operation to cause the head mover to move the discharge head to a position in the orthogonal direction, a discharging operation to cause the discharge head to discharge a liquid at the position, a medium conveying operation to cause the conveyor to convey the discharge target medium, and a changing operation to cause the head mover to change the position of the discharge head, and cause the head rotator to rotate the discharge head based on a length of droplets of the liquid landed on the discharge target medium by the above-described operations.

An integrated system for treating a thread and using the treated thread, comprising: a thread treatment machine for treating a thread or portions thereof; a thread applicator configured for using the treated thread such as a stitching machine of 3D printer; at least one mechanism for collecting and trimming thread portions; and a control unit, configured for controlling at least the thread treatment machine, the thread applicator and the collecting and trimming mechanism and for coordinating the treatment of the thread with the operation of the thread applicator, wherein the control unit is further configured for controlling the collecting and trimming mechanism for collecting untreated thread edge portions for allowing using only treated thread portions.
