Abstract

PURPOSE:To improve the resolution and accuracy of an encoder, by transferring a decoder, which reads a code in the encoder corresponding to the position of a bench, in accordance with the transfer of the bench. CONSTITUTION:A bench 2 is set transferrable back and forth along a guide 3 by means of a feed screw 4. A cylindrical encoder 7 is connected with the feed screw 4 and turns together with the screw 4. The revolution of the encoder 7 is reduced by a reduction gear 14 and transmitted to a feed screw 13 for a reading head 11 which is transferred along a guide 12 in accordance with the revolution of the encoder 7 to read out codes engraved on a spiral track 7a on the encoder 7. Values concerning the position of the bench 2 are observed by a light wave interferometer and coded to wright in corresponding positions on the track 7a. This system can improve the resolution and accuracy up to a level required, without regard to the screw grade.
