ABSTRACT:
FIELD OF THE INVENTION
The invention relates to an electronic page inverter for a mail processing system comprising:
a simple word processor system constituted, for example, by a CRT screen, a keyboard, a central unit, and a sheet-fed printer; and
at least one folder-inserter enabling the sheets of a letter to be placed in an envelope.
BACKGROUND OF THE INVENTION
When the system is small and produces a small quantity of letters, the printer is generally not mechanically coupled to the folder-inserter. Transfer is performed manually. The user takes the sheets at the outlet from the printer and inserts them in an inlet of the folder-inserter. Two types of printer need to be distinguished: some printers provide the sheets on which a letter has been printed in an order suitable for enabling the sheets to be inserted directly in an envelope. Other printers provide the sheets in an order that is unsuitable for direct insertion in an envelope since the addressee would find the last page in front of the first page. The user must therefore not only transfer the sheets manually, but must additionally change the order of the sheets.
To make such a system of mail handling more practical, the outlet of the printer could be mechanically coupled to the inlet of the folder-inserter. However, such mechanical coupling must solve the problem of inverting page order if the printer already owned by the user does not provide pages in the proper order for direct insertion in an envelope. A mechanical page inverter could be associated with the printer, such as described in European patent applications EP 0 365 283 and EP 0 398 187, however such mechanical devices are difficult to fit to an already-existing printer that a user does not want to change because of the cost of such a change.
OBJECT AND SUMMARY OF THE INVENTION
The object of the invention is to enable transfer to be performed automatically between a printer and a folder-inserter, when the printer is of the type that provides the pages of a letter in an order that is not suitable for direct insertion in an envelope, without requiring the entire printer to be changed, and without requiring major mechanical modifications to be made, and without requiring a change of word processor software.
The present invention provides an electronic page inverter for a mail processing system comprising:
a word processor system;
a sheet-fed printer;
means for electrically coupling the printer to said word processor system; and
a folder-inserter mechanically coupled to the printer to: receive the sheets on which the printer has printed the text of a letter; to fold said sheets; and to insert them in an envelope;
wherein the means for coupling the printer to the word processor system include means for storing a sequence of binary words representing a letter as said sequence is output by the word processor system, with the beginning of each page of text being identified; and for playing back said binary words page by page with pages being played back in inverted order, but with the characters making up each page being played back in the initial order.
A simple mail processing system that would otherwise have required pages to be transferred manually from the printer to the folder-inserter, and to be inverted manually, can thus be made more practical with the inverter as defined above since a simple mechanical device now suffices to couple the output of the printer to the input of the folder-inserter, page inversion being performed without using any mechanical device, but by using an electronic device which is very cheap to implement, and which is very easy for an unspecialized user to connect between the word processor system and the printer.
The invention also provides a folder-inserter including an inverter of the invention. Such a folder-inserter enables a user who already possess a word processor system and a printer that provides sheets in an order that is not suitable for direct insertion, nevertheless to implement a more sophisticated mail treatment system by adding a folder-inserter fitted with said inverter, thereby solving the problem due to the sheets being in reverse order.
