- the franking imprint contains one before entered and stored postal information including the Postage data for the transportation of the letter.
- One attached to the housing The compartment is used to hold an exchangeable ribbon cassette (US 4,767,228). While a door leading to the compartment can be opened at any time, access to the security area the printing device is prevented by a safety housing.
- the applicant's JetMail® franking machine is with a base and with a removable meter. Only the latter is through a suitably designed housing protected against misuse.
- the housing of the base which is a mail transport device and includes an inkjet printing device, none Have protective function and can be designed to be repair-friendly. Because the ink tank is separate from the printhead and replaced replacement of the printhead is not necessary. Also do not need any special safety measures for the printhead or to protect the control and data signals, if with a special piezo inkjet printhead a security imprint is printed with a mark, which is a review of the Authenticity of the security imprint allowed (US 6,041,704).

Beide Trennwände 63, 69 weisen in der Nähe des Druckposition gegenüberliegenden in Z-Richtung beabstandete Öffnungen 631, 691 für für die Transporttrommel auf. Zwischen der Trennwand 69 und der poststromausgangsseitigen Seitenwand 68 kann auf der gleichen Ebene wie die Bodenplatte 61 eine weitere Bodenplatte 612 angeordnet sein, durch welche ein zu frankierendes Postgut, das in nicht gezeigter Weise - in der Fig. 1 gezeigte - schlitzförmige Öffnung 21 des Gehäuseoberteils 2 gesteckt, d.h. in Z-Richtung zugeführt wird, in seiner Dicke ab der Brieflauffläche 290 in Y-Richtung begrenzt wird.
Die Seitenwand 57 bzw. die - nicht dargestellte - Seitenwand 58 sind mit Bolzen 571 bzw. 581 (nicht sichtbar) als Befestigungsmittel ausgestattet. Der Bolzen ist in einer Lageröffnung 371 bzw 381 (nicht sichtbar) der Seitenrandflächen 37 bzw. 38 (nicht sichtbar) drehbar gelagert, um welche die Chassisoberschale 5 drehbar ist, wenn die übrigen Befestigungsmittel 572 und 582 (nicht sichtbar) gelöst sind. Übliche Befestigungsmittel sind Wegbrechschrauben oder verplombte Schrauben.
Die Chassisunterschale 3 hat Lüftungsöffnungen 39 im rückwärtigen Abschirm- und Stützblechteil 36 und ggf. nicht gezeigte Lüftungsöffnungen in der Leiterplatte 4 nahe dem Bauteil 41.
Das querbeweglich zur Transportrichtung Z angeordnete Druckmodul hat neben der mindestens einen auswechselbaren Tintenkartusche 72, die in der Druckposition zum Teil in die Transporttrommel 73 hineinragt, einen Druckwagen 74. Nähere Ausführungen dazu sind der nicht vorveröffentlichten deutschen Patentanmeldung 100 32 855.5 entnehmbar, welche den Titel trägt: Vorrichtung zum Bedrucken eines Druckträgers.
An deren jeweiligen Rändern sind Lüftungsöffnungen 30, 51, 52 ausgebildet, wobei die geometrische Form des Randes der Funktionskanten ein Eindringen von Werkzeugen in den von beiden Chassisschalen eingeschlossenen Sicherheitsbereich unmöglich macht. Der Rand der Funktionskanten ist ∩-förmig ausgebildet, wobei sich eine innere Seitenwand 53 und eine äußere Seitenwand 55 ergibt.
Es ist eine Vielzahl einer alternativen Chassisanordnung im Rahmen der Ansprüche denkbar, wobei die vorgenannten Funktionskanten in der Form unterschiedlich ausgeführt sind und Lüftungsöffnungen an ihrem Rand aufweisen mit einer mehr oder weniger labyrintartigen Randstruktur, so das ein Eindringen von Werkzeugen auf geradlinigem Wege unmöglich gemacht wird. So können offensichtlich weitere andere Ausführungen der Erfindung entwickelt bzw. eingesetzt werden, die vom gleichen Grundgedanken der Erfindung ausgehend, die von den anliegenden Ansprüchen umfaßt werden.
Claims (7)

- Sicherheitschassis, nach einem der Ansprüche 1 bis 2, gekennzeichnet dadurch, daß Lüftungsöffnungen (50, 50', 50") am Rand (35, 35', 35") der ersten Chassisschale (3, 3', 3") und am Rand von Funktionskanten (54, 54', 54" bzw. 541, 541', 541") einer zweiten von der ersten beabstandeten Chassisschale (5, 5', 5") vorgesehen sind.
- Sicherheitschassis, nach Anspruch 1, gekennzeichnet dadurch, dass sich die Ränder der Chassisschalen (3, 3', 3", 5, 5', 5") gegenseitig umschlingen und in dabei in einem Winkel geformt sind, der ein Eindringen von Werkzeugen unmöglich macht.
- Sicherheitschassis, nach Anspruch 1, gekennzeichnet dadurch, dass mindestens eine der Funktionskanten L-förmig gestaltet ist.
- Sicherheitschassis, nach Anspruch 1, gekennzeichnet dadurch, dass mindestens eine der Funktionskanten mindestens einer der Chassisschalen U-förmig bzw. umgekehrt ∩-förmig gestaltet ist.
- Sicherheitschassis, nach Anspruch 2, gekennzeichnet dadurch, dass der Versatz nur soweit erfolgt, das ein Eindringen von Werkzeugen in den Sicherheitsbereich auf geradlinigem Wege unmöglich gemacht wird.
