ABSTRACT:
A gear arrangement includes a first gear wheel 10 having a section 12 with missing teeth. A second gear wheel 14 is arranged to mesh with the first gear wheel 10. The first tooth 16 on the first gear wheel 10 to engage with the second gear wheel 14 (following the missing teeth section 12) is resiliently movable inwardly within a radial slot 18 to withdraw when engaging an opposing tooth 22. A spring 20 urges the tooth 16 outwardly to one side of the opposing tooth 22 and into a gap on that side of the opposing tooth 22, so as to align the first and second gear wheels. Such a gear arrangement has particular use in a geared value setting mechanism provided on a print drum shaft of a postage meter.
