    摘要: A digital displacement measuring instrument includes a spindle screwed into a body to be axially advanced and retracted relative to the body; and an encoder that detects a displacement of the spindle. The encoder includes a rotor and a stator. The rotor is supported by a rotor bushing. The rotor bushing includes an engaging key engageable with a key groove axially provided on the outer circumference of the spindle, and is displaceable in the axial direction of the spindle via a position adjusting screw. The stator is fixed to the body via a stator bushing in the vicinity of the spindle so as not to be displaceable in the axial direction of the spindle.

    摘要: A measuring instrument includes a detector that outputs a measured value, a digital display unit, an analog display unit having a plurality of display segments, and a display controller. The display controller includes: a tolerance range display unit that lights or blinks display segments corresponding to a preset tolerance range relative to a preset value; a first determiner that obtains a difference between the present value and a present measured value and determines whether the difference is within an analog display range wider than the tolerance range; a difference display unit that lights a display segment corresponding to the last one or the last two digits of the present measured value when the first determiner determines that the difference is within the analog display range; a second determiner that determines whether the difference is within the tolerance range; and an acceptance or rejection display unit that displays a result determined by the second determiner.

    摘要: A measuring instrument includes a display that displays measurements. The display is provided by an organic electroluminescent display device or an electronic paper including an assembly of organic EL (Electro-Luminescence) devices. Since the display is provided by the organic electroluminescent display device or an electronic paper including an assembly of organic electroluminescence devices, visibility of the display can be enhanced. Further, since the display can be used for various measuring instruments in common and the display design can be easily changed, production cost can be reduced.

    摘要: A measuring instrument that includes a tube 21 having a female thread 211 and a spindle 3 having a lead screw 31 screwing with the female thread 211 and capable of being advanced and retracted in an axial direction along with rotation around the axial center, and measures dimensions etc. of a workpiece according to displacement in an axial direction of the spindle 3 based on a rotation amount of the spindle 3. According to this measuring instrument, a pitch P of the lead screw 31 is twice as large or more than the difference between an external diameter R and a core diameter r thereof, and the difference between the external diameter R and the core diameter r is one-fifth or less of the external diameter R. Because of the lead screw 31 with the large pitch, the spindle 3 can be moved at high speed, thus enhancing operational performance of the measuring instrument.
