  • a new and novel thermal postage meter assembly includes a number of modules of systems. It is an objective of this thermal postage meter to function such that upon the placement of an envelope on the deck of the thermal printer by an operator, the envelope encounters a position sensing assembly which should include an envelope stop arrangement to assure proper longitudinal envelope positioning. Upon proper positioning of the envelope on the deck, the position sensing assembly should senses the presents of the envelope and inform a microcontroller to first duck the positioning sensing assembly out of the way, inclusive of the stop assembly, and initiate the print sequence. Upon initiation of the print sequence, a platen roller assembly is positionable to bring the print area of the envelope into contact with the print ribbon of a thermal print ribbon cassette.
  • a postage meter thermal print head is located to act as a backing to the print ribbon and envelope.
  • the microcontroller is responsible for causing the positioning of the platen roller into a print position and for rotating the platen roller for printing. Following completion of the print cycle, it is desired for the microcontroller to cause the envelope to be ejected from the postage meter.

  • embodiments of the present invention present an envelope position stop assembly which, upon proper positioning of the envelope on the deck, assumes a second position during the printing process.
  • embodiments of the present invention present an envelope position stop assembly which further informs the microcontroller of the postage meter that the envelope has been ejected from the mailing machine.
  • a thermal postage meter is comprised of a number of system modules or assemblies.
  • the envelope Upon the placement of an envelope on the deck of the thermal printer by an operator, the envelope encounters a position sensing assembly which includes an envelope stop arrangement.

  • the envelope 25 hits the spring load trip finger 89 and the stop finger 124 which is retained by a locking lever 138.
  • the purpose of the stop finger 124 is to keep the envelope 25 from feeding too far through the print path and also to assure proper alignment of the envelope 25.
  • the trip finger 89 displacement by the envelope 25 actuates the sensor 106 mounted to the base 24 in response to the displacement of sensor tab 95.
  • the microcontroller 30 begins the print cycle. When the trip finger 89 is pushed forward about 4mm, it unblocks an optical sensor 106.

  • the platen roller 230 continues moving toward the envelope 25 until it closes the envelope 25 between the platen roller 230 and the print head 19 capturing the thermal ribbon therebetween.
  • the platen roller 230 will meet the envelope 25 at different points in the rotation of the shaft 83.
  • the ejection rollers 234 may still be above the feed deck.
  • the cam 83 will then continue to rotate, causing the links 208 to extend and both the link extension springs 210 and the ejection springs 227 to apply a load to the envelope 25.
  • the shaft 83 has rotated 180 degrees, the ejection rollers 234 are out of the feed path and the platen roller 230 is fully engaged. Printing can now begin.
  • the shaft 83 acts on the eccentric cam 208', the stop cam 135, the trip finger cam 105 and a set of flags 504.
  • the flags 540 trigger the microcontroller 30 when the shaft 83 has rotated 180 degrees.
  • the shaft 83 is driven by a DC brush-type gear motor 42 via a set of gears.
  • the flag 504 signals the microcontroller 30 that it is time to stop the shaft 83 rotation, the motor 42 is electronically braked.
  • the drive motor 44 and the ribbon drive motor 46 start under the direction of the microcontroller 30. It is noted that the motor 44 turns both the platen roller 230 and the ejection rollers 234. However, the ejection roller 234 is not in the supply path so it has no affect on the envelope 25.
  • the envelope 25 and ribbon begins to feed as the motor 44 is brought up to speed. Printing then starts by loading data to the print head from the print head controller 38 under the command instruction of the microcontroller 30 at a constant rate. The speed is monitored and controlled through the conventional motor encoder (not shown) on the motor 44. In the most preferred embodiment of the present invention, the printing operation takes about 425mS.
  • the ribbon While printing, the ribbon is driven through the print nip by the motion of the envelope 25.
  • the ribbon take-up motor 46 winds up the ribbon on the take-up core and provides even tension without pulling the ribbon through the print nip.
  • the back EMF of the motor 46 is monitored in the preferred embodiment. Changes in the back EMF indicate quantity of ribbon and the ribbon drive is modified accordingly by the microcontroller 30.
  • a sharp change in the back EMF of the motor indicates that the ribbon is broken after the print head or the ribbon has stopped, in either case, the microcontroller 30 aborts.
  • the ribbon is fed through a series of posts 416 and 421 which provides drag to the ribbon through the friction of the ribbon against the posts 416 and 421.
  • a light clutch load is provided by conventional clutch 335 on the ribbon supply core to provide tighter wrap of the ribbon around the posts 416 and 421.
  • the ribbon encoder 341 is turned by the friction of the ribbon moving past the roller 416.
  • the encoder motion 341 is monitored by the microcontroller 30 to determine if the ribbon breaks before reaching the print head or if the ribbon runs out, in which case, the microcontroller will abort.
  • the encoder 341 can be used to monitor the speed of the ribbon, and therefore the envelope 25, through the print nip.
  • the shaft 83 rotates an additional 180 degrees back to its original home position.
  • the drive link 208 becomes a solid assembly which pushes the ejection rollers 234 against the envelope 25. Since a lighter load is needed for ejection than for printing, the spring 210 becomes the only active spring.
  • flags 504 on the shaft 83 interrupt a optical sensor 506 to indicate 180 degrees of rotation. This 180 degree rotation engages the ejection roller 234 and disengages the platen roller 230.
  • the stop finger 124 and trip finger 89 are also released to extend above the feed deck. Due to their very light spring load, the levers 89 and 124 will ride along the bottom of the envelope 25 until it clears the platen roller 230.
  • the motor 44 continues to drive both rollers 230 and 234. At this point, however, the platen roller 230 becomes inactive because it is below the feed deck. At the same time, the ribbon motor 46 is stopped. When the ejection roller 234 engages, it feeds the envelope 25 from the printer at 2 to 3 times the print speed in the preferred embodiment. Once the envelope 25 clears the print nip, the stop and trip fingers 124 and 89, respectively, return to their home position. The drive motor 44 is stopped and the process is complete.
