A synchronous moving device includes: a device body; a movable portion which is provided in the device body; a feed screw shaft which is supported on the device body; a nut member which is thread-engaged with the feed screw shaft; a coupler which couples the movable portion and the nut member; and a cable binder which supports and guides a cable wired into the movable portion, wherein: the coupler includes a first member fixed to the movable portion, a second member fixed to the nut member, and an intermediate member interposed between the first and second members for absorbing deflecting motion of the feed screw shaft; and an end portion of the cable binder on a side of wiring of the cable into the movable portion is connected to the second member through a connection member and moved in synchronization with the movable portion.

Synchronous moving device and image measuring apparatus

A scale base is fixed to a base in a plurality of locations which are aligned in a measuring direction (a Y direction) in which measurement by a scale is carried out, slits are provided in the scale base in positions lying between the locations where the scale base is fixed to the base, the scale is supported by the scale base in two or more of the locations where the scale base is fixed to the base, and the scale base has gaps between the base and the scale base in positions other than the locations where the scale base is fixed to the base and between the scale and the scale base in the positions other than the locations where the scale base is fixed to the base.

Measuring apparatus

A stage apparatus () includes a stage glass () having on an upper surface a stage surface () of a substantially flat plane on which a predetermined workpiece (W) is set, a plane light emitter () with a flat plane, which is provided to substantially all over a lower surface of the stage glass () and illuminates the workpiece (W) with contour illumination through the stage glass (), and a supporting section (), which supports at plurality of points on a lower face side of the plane light emitter () and adjusts the flatness of the stage surface () by adjusting the height at a plurality of supporting points.

Stage apparatus and vision measuring apparatus

A touch signal probe comprises a fixed member, a movable member, a bias means, a drive member, a deformation touch signal processing circuit, a contact touch signal processing circuit, and a latch circuit. A stylus is attached to the movable member. The drive member relatively drives reseat position elements respectively placed on the fixed member and the movable member. The bias means restores the movable member to a still position. The deformation touch signal processing circuit generates a deformation touch signal. The contact touch signal processing circuit uses the reseat position elements as make-and-break electric contacts to generate a contact touch signal. The latch circuit inputs coordinate values every instant at which the deformation touch signal is output and stores the coordinate values as the most recent coordinate values for update, and when the contact touch signal is output, outputs the most recent coordinate values as detected coordinate values.
