Abstract
An angular encoder including a tensible tape scale having a scannable graduation and designed for taking circular angular measurements; and a tensioning device connected with one or both ends of the tape scale for tensioning the tape scale to adjustably position the one or both ends and having an actuation member, and a transmission mechanism for connecting the actuation member with one or both end(s) of the tape scale so that displacement of the actuation member results in a predetermined change of a position of the one or both ends of the tape scale determined by a transmission ratio of the transmission mechanism.
