Described is a feed mechanism for a slider which is convenient to use with good durability and low costs by eliminating a rack-and-pinion method. The feed mechanism allows the slider to be fed and moved along a longitudinal main scale. The feed mechanism includes a driving gear that is a gear train pivotally supported by the slider, a driven roller that meshes with the driving gear and rotates by rotation of the driving gear, and an arm that includes a cup portion capable of receiving the driven roller on a distal end. The arm includes the cup portion capable of receiving the driven roller on the distal end and is pivotally supported by the slider on a base end. The cup portion in a state of receiving the driven roller is biased toward the main scale by a pin plunger. Accordingly, the driven roller is kept abutted against the main scale.

Feed mechanism and measuring device including the same

A slide caliper of this disclosure includes: a fine adjustment measurement part including: a finger-press type rotation part; and a supporter, wherein the finger-press type rotation part includes: a roller part including two disks; and a roller shaft part, wherein at least a portion of inner surfaces of the two disks and the main scale come into contact with each other by frictional force, wherein the roller bearing part includes: an inclined surface along which the roller shaft part is movable when the measuring force is applied; and a stopper disposed at a position where the stopper and the roller shaft part come into contact with each other, and when the measuring force is applied, the frictional force with respect to the roller part is reduced as the roller shaft part moves along the inclined surface while contacting with the stopper to limit the measuring force.

Communication apparatus

In a switch ( ), a dimension between the first contact pin ( ) and a swing lever ( ) and between the second contact pin ( ) and the swing lever ( ) is set 5 mm. Accordingly, a detection value of the displacement sensor can be captured when a relative displacement not less than 5 mm is caused between the first and the second sliders, in other words, when the impulse or vibration caused by a contact of a probe against a workpiece is stilled, so that stable measurement is possible. In other words, the dimension of the workpiece can be accurately measured without being influenced by the impulse or the vibration caused when the probe touches the workpiece.

Linear measuring machine

A clamping assembly for attaching a probe device to an attachment arm of a measuring instrument which extends from the instrument along a first axis. The probe device has a base arm positioned adjacent to the attachment arm in an axially overlapping manner. The clamping assembly includes a first annular clamping member proximate the measuring instrument, a second annular clamping member positioned axially adjacent the first clamping member, a rotatable annular clamping ring encompassing the first and second clamping members, and an arrangement for offsetting a central bore of the second clamping member relative to a central bore of the first clamping member along an axis extending perpendicular to the first axis during a relative axial movement between the clamping ring and the first clamping member. The effect is to urge the base arm into abutment with the attachment arm in a direction along the second axis.
