Abstract
The disclosure provides a position changing device capable of reducing the size of the entire device in a plane. A position changing device (30) includes four pulley mechanisms (40). In the pulley mechanism (40), a toothed belt (45) is wound around a driving pulley (41) and a driven pulley (43), and is held between the driving pulley (41) and an idler roller (42) by the idler roller (42) and held between the driven pulley (43) and an idler roller (44) by the idler roller (44), and when the driving pulley (41) is driven by a driving mechanism (46), the position of a movable base plate (31) is changed.
Claims5
A position changing device changing a planar position of an operation machine, the position changing device comprising:
- a base having a planar upper surface;
- a moving member provided on the upper surface of the base to be movable within a predetermined range of the upper surface, and the operation machine being arranged at an upper portion of the moving member;
- and
- four moving mechanisms arranged on the base in a positional relationship of a quadrangular shape in a plan view to surround the moving member, and moving the moving member within the predetermined range,
- wherein each of the four moving mechanisms comprises:
- an elongated member having flexibility, and two ends of the elongated member being connected to the moving member;
- a plurality of first rotating members arranged outside the predetermined range of the moving member on the base and wound with the elongated member, and the plurality of first rotating members being rotatable around an axis line extending in a vertical direction;
- a second rotating member provided to be rotatable around the axis line extending in the vertical direction, and holding the elongated member between the second rotating member and each of the plurality of first rotating members;
- and
- a driving mechanism moving the moving member within the predetermined range via the elongated member by rotationally driving at least one of the plurality of first rotating members around the axis line, and stopping the moving member by stopping rotational driving.
