An absolute position measuring device includes a main body, a spindle (300), a rotary encoder (500), a linear encoder (600), and an arithmetic processor (720). The rotary encoder (500) has a rotor plate encoder (520) that rotates integrally with the spindle (300). A rotary cylinder (530) rotates integrally with the spindle (300) and has an external thread (531). A nut member (610) is engaged with the external thread (531) of the rotary cylinder (530) in a rotation stop state. The linear encoder (600) has a slider (620) that slides together with the nut member (610), and a detection scale (630) that detects the slider position. The rotary encoder (500) absolutely detects the rotary angle of the rotor plate (520) within one revolution, and the linear encoder (600) absolutely detects the position of the slider (620).

The invention relates to a handheld measurement instrument (10) and a configurator (80) forming a measurement kit. The measuring instrument (10) and the configurator (80) are provided each with an interface (30, 35, 36, 84, 86, 87), enabling communication between the measuring instrument (10) and the configurator (80). The handheld measurement instrument (10) further comprises a measuring unit (21, 21a, 21b) for measuring distances or angles of an object by contacting physically distinct points of said object; and a circuit unit (50) applying a function of a functionality on electronic signals/electronic measurement results delivered from the measuring unit (21, 21a, 21b) in order to deliver the measuring results in a desired form to the user by output means (28). The form the results should be presented can be selected by the user using input means (26) of the measuring instrument (10). The circuit unit (50) is configurable by the user using the configurator (80) in order to determine, with which functionality the circuit unit (50) and the input means (26), respectively should be equipped.

A micrometer (1) includes: a frame (10); an anvil (11); a spindle (20); an encoder (40); a display (60); a strain gauge (50) that detects a deformation of the frame; a storage that stores a change amount of the detection value (a displacement of the spindle detected by the encoder) per a unit deformation detected by the strain gauge, as a compensation factor; and a compensator that compensates the detection value based on a difference between a zeroset-time deformation that is detected by the strain gauge when a command for zeroset is given and a measurement-time deformation that is detected by the strain gauge in measurement, and based on the compensation factor stored in the storage.

A displacement measuring instrument includes a spindle (10) screwed to a stationary sleeve (20), a thimble (30), an operation sleeve (40), and a constant pressure mechanism (50). The constant pressure mechanism (50) includes: a rotary driving element (51) rotatable together with the operation sleeve; a rotary driven element (52) coupled to the rotary driving element in such a manner as to be rotatable together with the rotary driving element but not to be rotatable when a predetermined or more load is applied to the spindle; and a rotation transmitting mechanism (53) transmitting a rotation of the rotary driven element to the spindle. A male thread portion (23) with the same pitch as that of a male thread portion (12) of the spindle is formed on the outer circumference of the stationary sleeve. A female thread portion (31) is formed on the inner circumference of the thimble and screwed to the male thread portion of the stationary sleeve.
摘要:
A thimble (5) and a spindle (4) are rotated through a first constant-force device (70) by rotating an operation sleeve (6) integrally having a first operation section (61) and a second operation section (62). When a more than predetermined load is applied to the spindle (4), the first constant-force device (70) is actuated to spin the operation sleeve (6) idly. Since the operation sleeve (6) integrally has the first operation section (61) and the second operation section (62), both double-handed operation for holding the frame by left hand and rotating the first operation section (61) by right hand and single-handed operation for holding the frame and rotating the second operation section (62) with a single-handed are possible while retaining the same operability as in conventional operation during measurement.
