ELECTRIC MICROMETER |
摘要 |
An electric micrometer with a U-shaped frame has a contact-type rotary encoder comprising a disk which has conductor patterns thereon, and a rotary brush holder which holds rotary brush contacts. The rotary brush holder is rotated by rotation of a spindle. A coupler connects a sleeve journaled to the spindle with the rotary brush holder so that the rotary brush holder rotates together with the sleeve and the spindle but need not have the same rotational axis as the sleeve. Integral to the frame is a count-and-control circuit which counts the output signal of the rotary encoder and indirectly computes a distance between the frame and an end of the spindle, and a digital indicator which is disposed on a part of the frame and indicates the computed distance. |
