A postage meter has a locking cam follower so that locking arms on the print wheels of the postage meter are able to lock the wheels from unintended movement when the print rotor is out of its home position. Stiff runners are provided below guide rods of setting racks in the rotor so that the racks cannot be displaced away from the value wheels. A sensor is placed on the rotor cover with the meter software set up to keep a print cycle from starting if the cover is open. A cam on the rotor makes it impossible to open the cover when the rotor is out of the home position. A latch holds the cover shut, and the only way the latch can be released is if the meter software releases it, for example by sliding a rack to a position that triggers the latch. Cogs and cog teeth are used instead of gears and gear teeth to reduce the possibility of unintended movement of the value wheels. Rotating disks lock the racks when the rotor is not in the home position.

Tamper-resistant postage meter

A postage meter has a secure housing, an accounting register within the secure housing, and a print rotor the rotation of which defines a paper path. The rotor axle is formed of two halves, and within the two haves is a lengthwise cavity along which setting racks are capable of axial movement. The racks engage with print wheels at one end and are accessible to the main body of the postage meter at the other end. Each rack engages with its value wheel in a rack-and-pinion engagement. The axle halves are made of plastic and they snap together. The racks slide within grooves, and are held in place with pins. The axle has journal bearings and a thrust bearing defining its movement relative to the secure housing. A worm gear in the housing engages a worm wheel in the rotor to bring about rotation of the rotor for the printing of postage.

A postage meter has the print rotor and platen within a single secure housing, with a letter detection lever along the paper path downstream from the rotor. The letter detection lever is in a spring-loaded coupling relationship with the trigger that triggers franking. If a letter remains in the meter due to a paper jam, the detection lever continues to be actuated and the spring-loaded coupling keeps the trigger in the triggered position. The meter further comprises a platen carrier moving the platen toward and away from the rotor; when the rotor is in its home position a radial cam on the rotor and cam follower keep the carrier away from the rotor. When franking of a letter begins and the rotor begins to rotate, the rotor cam releases the cam follower, permitting the carrier to move up in spring-loaded relation toward the rotor. A letter stopper is in the paper path downstream from the rotor and helps to align the letter so that the postage imprint is optimally oriented on the letter. The trigger includes an enclosure containing a free-moving mass; the weight is constrained from radial and axial movement relative to the trigger pivot. The trigger is balanced in two axes in the plane in which it rotates, thus it has no net moment (or minimal net moment) about its pivot. The mass and the enclosure shape are selected to damp movement of the trigger as it returns to its home position after it is triggered.

Postage meter with improved paper path

A postage meter has a secure housing and a printing means and accounting register within the secure housing. Formed in the secure housing is postal lock. In the postal lock, a door is movable between first and second positions relative to a cavity. When the door is closed (in its first position) it renders the cavity inaccessible, and when the door is open (in its second position) it renders the cavity accessible. The door has a latch. The latch is spring-loaded so that it engages a latch feature in the cavity and holds the door closed. Pushing the latch the other way (against the spring) causes the latch to engage a pawl in the cavity, and the pawl tends to push the door open. A protruberance on the rear of the door engages a locking gear in the cavity. The locking gear allows separation of two halves of the meter housing, or holds the two halves together. If the locking gear is in the position that permits separating the halves, then the door cannot be closed because the gear abuts with the protruberance. Only if the gear is in the locked position is it possible to close the door fully. The door is set up to accommodate postal regulations of many countries, including countries requiring a key and lead seal, a paper seal, a lead seal by itself, or a lead seal and paper seal.

Postage meter with improved postal lock

A self-contained postage meter does not have a base separable from a main body. The single secure housing contains everything that would be in the main body of a prior art postage meter and everything that would be in a prior art meter base. Despite containing all these things, the single secure housing is small enough and light enough in weight to permit the entire meter to be readily transported to the post office for inspection or resetting. Within the single secure housing are the print rotor with value wheels, all the mechanisms for setting the print wheels, the descending and/or ascending register and associated microprocessor, and all the mechanisms for transport of the mail piece through the meter. Only a handful of controlled elements are required, chiefly a single inexpensive DC motor for franking and value wheel setting and a few electromagnets. Two one-way clutches are used so that rotation of the motor in one direction accomplishes a setting cycle for the value wheels and rotation of the motor in the other direction accomplishes a printing (franking) cycle.

Single-motor setting and printing postage meter

Postage meter

A postal-lock mechanism for preventing unauthorized recharging of a postage meter and identifying tampering of a postage meter is disclosed. It contains a cylinder-like assembly mounted in the postage meter housing. The postage meter is 'locked,' i.e. made inaccessible for adding postage, when the postal-lock is in a predetermined angular position. To add postage to the meter, the postal-lock is rotated to activate a limit switch in the meter, subsequent to which action additional postage may be added, for example via keyboard. The postal-lock mechanism also locks the meter housing to the meter chassis, obviating the need for a separate locking mechanism. The postal-lock mechanism may be used in conjunction with a wire and lead seal, a frangible membrane, a wire and lead seal and a frangible membrane, a key lock, or a key lock and a wire and lead seal.
