Roland DG has filed a patent for a table mover that allows for smooth movement of a table unit along a slide rail. The table mover includes a table carriage that supports the table and is movable in sub-scanning directions. The table carriage is equipped with fixers that are elastically deformable in different directions, allowing for flexibility in movement.

Table mover with smooth movement along slide rail
A recently filed patent (Publication Number: US20230271436A1) describes a table mover for use in an ink jet printer. The table mover includes a base with a bottom wall and two side walls extending upward in a first direction. Fixed to each side wall are slide rails that allow for the movement of a table assembly in the first direction. The table assembly consists of a table and a table carriage that supports the table. The table carriage is supported by two sliders, one engaged with each slide rail. The sliders are coupled to the table carriage by fixing brackets.
One unique feature of the table carriage is the inclusion of a first fixer and a second fixer, with the first fixer being more easily elastically deformed in a second direction than the second fixer. This allows for flexibility and movement of the table carriage in the second direction. The first fixer can be elastically deformed by a notch in the table carriage, which includes a first notch extending in the first direction and a second notch extending vertically at each side of the first fixer in the first direction.
The table mover also includes a coupler with a support and a coupling portion that is elastically deformable in a third direction perpendicular to the second direction. The coupler is coupled to the first fixing bracket, which is fixed to the first fixer of the table carriage. The weak portion of the coupler includes an opening that allows for elastic deformation.
The patent also describes the use of supporting brackets that are supported by the sliders from below to provide additional stability to the table carriage.
The table mover described in the patent is intended for use in an ink jet printer, where it can be combined with a guide rail, a carriage, and an ink head to create a complete printing system. The ink head includes multiple nozzles for discharging ink onto a recording medium placed on the table.
Overall, this patent describes a table mover with unique features that allow for flexible movement in multiple directions, making it suitable for use in ink jet printers.
