  • the one on a piece of mail graphic symbols can be printed with a suitable reader can be entered automatically.
  • the invention relates in particular to franking machines, which generated a fully electronic impression Franking of postal items including reprinting one Deliver advertising clichés and a marker.
  • the franking machine is with at least one input means, an output means, an input / output control module, a memory for at least one advertising cliché, one Control device and a printer module equipped.
  • a franking machine usually creates an imprint right-justified in a form agreed with Swiss Post, starting parallel to the upper edge of the mail with the content of postage in the postmark, date in Daily stamps and stamp impressions for advertising slogan and if necessary, type of shipment in the election stamp.
  • the post value that The date and the type of shipment form the according to the variable to be entered in the mail item Information.
  • the post value is that of the sender prepaid transportation fee (franking), the one taken from the refillable credit register and at Postage is used.
  • the date is a current date or a future date in a postmark. While the current date of a clock / date block automatically provided, must be in a manual Predating a setting of the desired one future date. Interesting is the pre-dating in all cases where the advent occurs Postage processed and franked very early, but too must be dispatched to a specific date.
  • the embedding of the variable data for the date in the In principle, day stamps can also be used for printing of the postal value.
  • the approved advertising clichés can send a wide variety of messages kind contain, especially the Address, company logo, mailbox and / or one any other message. Acting in the advertising cliché it is an additional one in the postal sense Information to be agreed with the postal authority.
  • a franking machine message printing system is already known from DE 37 12 100 known, the ones to be printed Characters, a postage charge, and a remote Include message.
  • the electrical franking machine is with a franking machine accounting circuit, which delivers the postage value, with a Telephone or transmission connection, with a message input device, with a transmission control system, with a printer and with a memory equipped.
  • the memory delivers the message, therefore the characters to be printed are at least partially printed based on data stored in memory.
  • Advertising cliché can be selectively changed by the data center
  • the data center via the transmission connection is forwarded to the verification of the coded Requirement in the data center was positive and that of Data center transmitted message in the franking machine has been checked.
  • the possibility of a third party To allow advertising on your own post by the Space for the franking machine message rented becomes.
  • the data center then becomes the message of one Transmitted to third parties.
  • the data center needs the message of the third party to the franking machine and checked also the use of the message in the Franking machine. But there are always measures required to ensure that the connection the embassy is maintained authorized and that the data is correct.
  • Selective change in the memory saved advertising message must either the pixel data for the advertising message completely new from one Central are transmitted, the number of Print is monitored, or the one to be printed Advertising message is hand in using a keyboard entered a memory to successively save the Print postage, date and text lines.
  • the disadvantage here is that manual changes Input information the previous old input information is lost. Only on at the headquarters saved advertising messages can then be used become. Another disadvantage is that the change is not can be done without interruption.
  • the squeeze is electronically and mechanically complex. The usage on the one hand from printing drums or on the other hand from Dot matrix printers also leads to an undesirable one Noise pollution.
  • An electronic franking machine is known from US 4,580,144 known with two thermal printing devices, with the first the fixed part of the printed image (postal code and picture frame) and with the second one variable print image part (postage and date) one after the other to be printed.
  • the treatment of variable and constant data can Print speed can be increased.
  • An automatic transmission system is known from EP 294 397 known with user (chip) cards.
  • the user cards are with a microprocessor and a data output unit Mistake.
  • the franking machine points a terminal for the user cards with a value processing section, Programming means for card microprocessor and a processing section microprocessor for execution of a programmed handling procedure on, with a graphic from the card memory by Terminal is loaded into the printer memory.
  • With new advertising clichés here Security itself cannot be increased. Such one can be easily generated electronically. On the other hand would change a cliché on manipulation Clues. To evaluate such, but is through the postal authority has not yet envisaged here.
  • DE 38 23 719 is a security system for use with a character printing authorization device known.
  • a computer of the franking machine is a memory for the data to be loaded Graphic change and the date of the associated date.
  • an external dialing device via a connecting device (Modem) accessed a selection of one too character pattern. It is intended that the printed character pattern to check security the authorization of the franking machine becomes. But here is all of that printed printed image from the Post office evaluate what is only with a high Effort is possible.
  • Another security system uses imprints in Form of a diagram (US 5 075 862) within the Franking machine stamp imprint. If pressure elements failed, the dots are missing in the printed image, which leads to signal an alleged forgery can. Such markings in diagram form within the Franking machine stamp imprints are therefore not so for sure. Even if the impression is correct, the machine evaluation is difficult because the whole Print image is to be evaluated.
  • DE 40 03 006 A1 describes a method for Labeling of postal items to enable identification been proposed by franking machines, including a multi-digit crypto number the date, the machine parameters, the postal value and of the advertising cliché and cached separately becomes.
  • a printer media setting Printer control becomes the crypto number when printing additionally inserted in the print pattern. So can a counterfeit or any imitation using the crypto number of the franking machine stamp by an unpaid one Postage imprint can be recognized.
  • the user can easily find out who manipulated the post value. However this is not a fully electronic one generated print image for an impact-less printer.
  • the fully electronic generated advertising cliché belongs in this solution as well as the constant data of the franking image, such as the frame arrangement of the value and day stamp with Location and, if applicable, the postcode.
  • the advertising slogan but can not partially in that franking machine be changed.
  • a franking device for which, on the one hand, a machine-readable as well as manually readable and decodable form of the identification, which can be visibly applied to the mail piece or the franking strip together with the franking imprint, and for which, on the other hand, a solution for combining constant and of quickly changeable editable data as well as for printing control for a column-wise printing of a franking image was developed.
  • the cliché should be changed via the actuating elements in the new franking machine, without this requiring prior approval from a data center or through the post office, and without this affecting the security of the billing and without such franking Postgut is sorted out as a forgery at the post office. At the same time, the security against counterfeiting should also be increased.
  • This marking is preferably in the form of a Barcodes and / or a series of symbols in one Field of the franking machine image at the same time this is printed by the only printer module.
  • the symbolism becomes mechanical as well a visual evaluation by a trained Examiner checking the shape and conceptual content of the symbols evaluates, made possible in the post office.
  • the shape of the symbols, with orthogonal edges, made possible by an integral Measurement of the degree of blackening is a particularly simple one and fast machine readability. Opposite the bar code becomes a higher information density with the row of symbols reached and thus space in the franking machine print image saved or can be saved using the graphic Symbols more information can be printed coded.
  • a control device that does the billing and Sequence control takes over, creates, is therefore provided that a print control signal after a print request is formed by converting it into binary pixel data converted marker data during the column by column Printing in the course of a special printing routine column by column into the currently printed column at a predetermined one Position.
  • the invention assumes that after switching on automatically the post value in the value print accordingly the last entry before the franking machine was switched off and the date in the day stamp corresponding to the current date can be specified for the reprint the variable data into the fixed data for the frame and for all related data that remain unchanged be electronically embedded.

  • Those variable data, which during the Pressure embedded in the print column include at least the marking data. The time spent on the previous assembly of the entire pixel image with the rest of the data, is reduced accordingly.
  • the previous assembly is similar to that of Date in the postmark and as with the postage value in the value print, the variable information in the intended Windows added and modified afterwards can be. It is assumed that a Embedding a variable part of the text in a frame for an advertising cliché can be done in the same way, as with the other window data and that for that Window within the overall presentation of the advertising cliché is defined. To save time, be only the parts of a graphic representation of one Resaved change that actually changed become.
  • the procedure goes in preparation for a change of the cliché text part for franking machines assume that a loading of agreed cliché types via MODEM or Chipcard and a selection of a cliché type in on can be done in a known manner.
  • According to the invention becomes an optional editing one in the franking machine stored cliché text part and a composition and the display of an overall presentation and if necessary, saving the edited text part additionally guaranteed before printing.
