Abstract
A locking arrangement is disclosed for a machine, such as a postage meter, which includes a rotatable member (12) which rotates when the machine performs an operating cycle and a mechanical or electromechanical register (22; 20) for being incremented or decremented in response to operation of the machine. The arrangement includes a clutch (24) arranged between a fixed structure or member (28) and the rotatable member (12) the clutch being operable to engage or release said fixed structure or member. Means (60; 78) are associated with the registers (22; 20) for actuating the clutch to prevent rotation of the rotatable member (12) when the register displays a predetermined value.
