An inkjet printer for forming, on a base, an image layer and an adhesive layer on which foil is to be formed includes a first head, a second head, and processing circuitry. The first head discharges an ink for the image layer. The second head discharges inks for the adhesive layer including a first ink and a second ink. The second ink has a lower wet spreadability than a wet spreadability of the first ink. The processing circuitry controls the second head to form an image area included in the adhesive layer with the second ink in a case where a width of the image area is less than a threshold, and form the image area with the first ink in a case where the width of the image area is not less than the threshold.

A thread-coating module includes: a coating chamber having a thread entrance at one end and a thread exit at an opposite end thereof; and an inkjet printhead positioned in a printhead opening of the coating chamber for ejecting ink onto thread fed through the coating chamber. The coating chamber has an ink management system positioned opposite the printhead for managing excess ink. The ink management system includes: an inner ink-collection slot in fluid communication with a drain port for recycling excess ink and an outer aerosol-collection chamber fluidically connected to a vacuum port.

A thread-coating module includes: a base plate having a printhead opening; an inkjet printhead received in the printhead opening; and a chamber unit having a mouth for engagement with the base plate and an ink-collection slot opposing the printhead. The chamber unit and the base plate are movable relative to each other for opening and closing a coating chamber comprising the base plate and the chamber unit, with the ink-collection slot being positioned opposite the printhead in the coating chamber.

A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.

An adjusting mechanism includes an adjusting plate and a screw type adjuster. The adjusting plate is provided in at least one end of an interlocking shaft that interlocks a pair of driving belts provided in a second direction and is attached to an end of the interlocking shaft. The screw type adjuster is configured to be capable of adjusting a position of a moving body engaged to the pair of driving belts by being rotated to move the adjusting plate along a first direction different from the second direction.

An image forming apparatus includes a conveyance part, a head unit, a distance changing part, three blocks and three pins. The distance changing part moves the head unit between a printing position where a printing operation is performed and a retreat position separated away from the conveyance part farther than the printing position. The three blocks are provided in one of the conveyance part and the head unit at intervals in the conveyance direction and a width direction crossing the conveyance direction. The three pins are provided in the other of the conveyance part and the head unit at positions facing the three blocks. Each of the three blocks has a positioning groove having a pair of inclined surfaces. The pins come into two-point contact with the inclined surfaces of the blocks in a state where the head unit is positioned in the printing position.

An inkjet recording apparatus includes a recording unit, a head unit, a frame, and an angle adjustment mechanism. The angle adjustment mechanism includes an angle adjustment member, a biasing member, and an operation member. The angle adjustment member is in contact with the head unit and is rotatable about an adjustment rotation shaft extending parallel to the unit rotation shaft of the head unit. The biasing member biases the angle adjustment member in a direction of rotating the angle adjustment member in a first direction. The operation member contacts the angle adjustment member and rotates the angle adjustment member in a second direction opposite to the first direction against a biasing force of the biasing member. The angle adjustment member is configured by of a plurality of shaft members.

A liquid jet head and a liquid jet recording device capable of reducing the installation area of the liquid jet head are provided. The liquid jet head according to an embodiment of the present disclosure is to be installed in a carriage of the liquid jet recording device. The liquid jet head includes a jet section provided with a nozzle hole configured to jet liquid, a support member configured to support the jet section, and provided with a hole part including a through hole penetrating in a jet direction of the liquid, a biasing member disposed in the hole part, and configured to bias the support member toward the carriage, and a biased member which is disposed at a predetermined position with respect to the carriage, and is biased in the hole part by the biasing member to thereby set a position of the nozzle hole with respect to the carriage.

The ink jet device is provided with a plurality of ink jet heads including a plurality of nozzles disposed linearly with each other at intervals in a predetermined longitudinal direction and ejecting ink in different regions each other in the printing width direction; and a position adjusting mechanism performing rotating operation of changing the intervals in the printing width direction of the nozzles by rotating the plurality of ink jet heads around an axis perpendicular to the print surface of the print object, and performing a shifting operation of shifting at least one of the plurality of ink jet heads in the printing width direction.

A recording-head position adjustment mechanism adjusts a position of a recording head. The recording-head position adjustment mechanism includes a first support, a second support, and an adjuster. The first support supports a first end of the recording head in a longitudinal direction of the recording head. The second support supports a second end of the recording head in the longitudinal direction. The adjuster moves the second support with respect to the first support in a transverse direction intersecting the longitudinal direction to adjust an inclination of the recording head.
