摘要： In an inkjet printer, from one side of a main scanning direction, first through fourth ultraviolet irradiation devices arrayed in the main scanning direction at least partially overlap first and second recording heads. A distance in the main scanning direction between a middle position in the main scanning direction of the first recording head and a middle position in the main scanning direction of the first ultraviolet irradiation device is equal to a distance in the main scanning direction between the middle position of the first recording head and a middle position in the main scanning direction of the second ultraviolet irradiation device. A distance in the main scanning direction between a middle position in the main scanning direction of the second recording head and a middle position in the main scanning direction of the third ultraviolet irradiation device is equal to a distance in the main scanning direction between the middle position of the second recording head and a middle position in the main scanning direction of the fourth ultraviolet irradiation device.

摘要： A recording medium take-up mechanism and a printer prevent a recording medium having been printed from easily twisting when winding the recording medium. A printer includes a platen supporting recording paper that is delivered frontward during printing, a take-up shaft on which the recording paper having been printed is wound, a tension bar configured to impart tension to the recording paper by pressing a portion of the recording paper that is between the platen and the take-up shaft, a support arm supporting the tension bar, and a support shaft pivotably supporting the support arm. A center of the support shaft is positioned inside a contour of the take-up shaft, as viewed in an axial direction of the support shaft.

摘要： A printer includes ink heads, an ink head conveyor, caps, a conveyor, suction pumps, opening passages, suction passages, and cap valves. The suction pumps are each provided for an associated one of the caps. The suction passages each connect an associated one of the caps to an associated one of the suction pumps. The conveyor 50 includes a base, a movable table, a guide wall, and a spring. The movable table supports the caps and includes a table wall extending upward from an end of the movable table facing in a first direction extending to a cap attaching position in a main scanning direction. The cap valves are disposed on a surface of the table wall facing in the first direction.
