Abstract
A fader device includes a plurality of shafts disposed parallel to each other, and a moving body attached to the plurality of shafts and movable in a longitudinal direction of the plurality of shafts. At least one of the plurality of shafts is a screw shaft with a male thread on an outer periphery thereof and is configured to be rotatable about an axis extending along the longitudinal direction. At least one of the plurality of shafts other than the screw shaft is a guide shaft that guides the moving body in the longitudinal direction. The moving body meshes with the male thread to move in the longitudinal direction as the screw shaft rotates.
Claims5
A fader device comprising:
- a screw shaft extending in a linear direction and including a male thread on an outer periphery thereof, the screw shaft being rotatably supported so that the screw shaft is rotatable about an axis thereof extending in the linear direction;
- a moving body attached to the screw shaft and meshes with the male thread to move in the linear direction as the screw shaft rotates, the moving body including:
- an insertion portion;
- a mounting portion that meshes with the male thread;
- and
- a coupling portion that couples the insertion portion and the mounting portion;
- a partition member that separates a first region where the screw shaft is located from a second region that is different from the first region, the partition member including a slot that extends in the linear direction and through which the insertion portion of the moving body extends through from a side of the first region to a side of the second region;
- and
- a cover member positioned between the screw shaft and the slot of the partition member in the first region and extending in the linear direction,
- wherein the cover member is interposed between the insertion portion and the mounting portion, and
- wherein the coupling portion surrounds the cover member as viewed in the linear direction.

- a partition member that separates a first region where the screw shaft is located from a second region that is different from the first region, the partition member including a slot that extends in the linear direction and through which part of the moving body extends through from a side of the first region to a side of the second region;
- and
- a cover member positioned between the screw shaft and the slot of the partition member in the first region and extending in the linear direction, wherein the cover member:
- is tubular shaped surrounding the screw shaft and the mounting portion;
- includes an elongated opening extending in the linear direction and connecting an inside and an outside of the cover member, the elongated opening facing an opposite side of the partition member.
