Abstract
A locking arrangement of a tape spool hub with respect to a rotating shaft is obtained by outwardly extendable levers that press the tape spool hub to a rotary drive such that the spool is centered in a driving position on a support base on the rotating shaft and is also prevented from accidentally falling off the support base.
