Attached to the postage meter are a plurality of cross-over shafts with pinion gears, the pinion gears engage the racks to facilitate value selection. The postage meter also includes a rotary shutter device, the shutter device prevents unauthorized movement of the rack members and unintended rotation of the drum member.
