Description

Die Erfindung betrifft einen elektronischen Kleinrechner, bei dem integrierte Rechnerschaltungen, eine Anzeigevorrichtung und mit den Tasten eines Tastenfeldes zusammenwirkende feste Gegenkontakte auf einem gemeinsamen Substrat angeordnet sind, wobei die Anzeigevorrichtung auf einem und die Gegenkontakte auf einem anderen Endabschnitt des Substrats angeordnet sind.The invention relates to a small electronic computer in which integrated computer circuits, a Display device and with the keys of a keypad cooperating fixed mating contacts on a common substrate are arranged, the display device on one and the mating contacts are arranged on another end portion of the substrate.

Bei einem Kleinrechner mit diesen Merkmalen, der bekannt ist aus »Electronics«, 24. Mai 1973, Seiten 5E und 6E, besteht das Substrat aus einer Glasplatte, die einen Teil einer Flüssigkristallanzeigevorrichtuitg bildet und zusätzlich die Rechnerschaltungen und die Gegenkontakte für die Tasten trägt. Solche Substrate können nur für einen bestimmten Rechnertyp zugeschnitten werden. Für verschiedene Rechnertypen unterschiedlicher Abmessungen, beispielsweise zwischen dem Tastenfeld und dem Beobachtungsfenster Für die Anzeigevorrichtung, müssen unterschiedlich bemessene Substrate hergestellt werden. Die Verwendung ein und desselben Substrattyps für verschiedene Rechnertypen, bei denen die Anzeigebeobachtungsfenster unter verschiedenen Winkeln zur Rechneroberfläche angeordnet sind, ist bei dem bekannten Rechner ni^ht möglich. Bisher war es also erforderlich, für jeden Rechnertyp ein individuell zugemessenes Substrat herzustellen. Dies erforderte unterschiedliche Herstellungsanlagen oder mindestens eine Umstellung der Herstellungsanlagen zur Anpassung an den jeweiligen Substrattyp. Dies ist bei Massenproduktionsmethoden, die bei Massenprodukten, wie sie elektronische Kleinrechner inzwischen darstellen, erforderlich sind, hinderlich und kostentreibend.In a small computer with these features, which is known from "Electronics", May 24, 1973, pages 5E and 6E, the substrate consists of a glass plate which forms part of a liquid crystal display device and additionally carries the computer circuits and the mating contacts for the keys. Such substrates can can only be tailored for a specific type of computer. Different for different types of computers Dimensions, for example between the keypad and the observation window for the Display device, different sized substrates must be made. Using a and the same substrate type for different types of computers, in which the display observation windows are arranged at different angles to the computer surface is not possible with the known calculator possible. So far it was necessary to have an individually measured substrate for each type of computer to manufacture. This required different manufacturing plants or at least one conversion of the Manufacturing systems for adaptation to the respective substrate type. This is with mass production methods, which are required for mass products, as they are now represented by small electronic computers, cumbersome and expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen elektronischen Kleinrechner der eingangs angegebenen Art verfügbar zu machen, der sich mit Massenproduktionsmethoden möglichst effizient herstellen läßt und mit einem hinsichtlich der Rechnergehäusegegebenheiten möglichst vielseitig einsetzbaren Substrat versehen ist.The invention is based on the object of providing a small electronic computer of the type specified at the beginning To make available species that can be produced as efficiently as possible using mass production methods and provided with a substrate that is as versatile as possible with regard to the computer housing conditions is.

Die Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben.The solution to this problem is given in claim 1.

Dadurch, daß ein flexibles Substrat verwendet wird, das in einem Endabschnitt serpentinenartig faltbar ist, ist nicht nur ein geringerer Gehäuseraum ausreichend, sondern kann man auch ein Substrat, das an sich für einen Rechnertyp mit größeren Längenmaßen konzipiert ist, ia einem kürzeren Rechner verwenden, indem man den Zwischenbereich stärker zusammenfaltet EinBy using a flexible substrate which can be folded in a serpentine fashion in one end section, Not only is a smaller housing space sufficient, but you can also use a substrate that is in itself for a type of computer with larger length dimensions is designed, ia use a shorter computer by using the intermediate area is folded up more tightly

ίο besonderer Vorteil ist darin zu sehen, daß der die Anzeigevorrichtung tragende Endabschnitt des Substrates aufgrund der Faltung des flexiblen Substrates sowohl in Längsrichtung des Rechnergehäuses als auch hinsichtlich seines Winkels gegenüber der Ebene des Tastenfeldes eingestellt oder verstellt werden kann. Ein und dasselbe Substrat kann somit für verschiedene Rechnertypen verwendet werden, die sich in der Winkellage ihres Anzeigebeobachtungsfensters voneinander unterscheiden. So gibt es bekanntlich Kleinrechner, bei denen das Anzeigebeobachtungsfenster in einer Ebene liegt, die parallel zur Ebene des Tastenfeldes verläuft, während es andererseits Rechner gibt, bei denen das Anzeigebeobachtungsfenster unter einem bestimmten Winkel gegenüber der Ebene des Tastenfeldes schräg gestellt ist, um eine bessere Ablesbarkeit zu erreichen, wenn man einen solchen Rechner als Tischgerät benutzt Für derart unterschiedliche Rechnertypen läßt sich aufgrund der erfindungsgemäßen Maßnahmen ein und dasselbe Substrat verwenden.ίο particular advantage is to be seen in the fact that the Display device carrying end portion of the substrate due to the folding of the flexible substrate both in the longitudinal direction of the computer housing and in terms of its angle with respect to the plane of the Keypad can be set or adjusted. One and the same substrate can thus be used for different Computer types are used which differ in the angular position of their display observation window from one another differentiate. As is well known, there are small computers in which the display observation window is in a Is plane that runs parallel to the plane of the keypad, while there are computers on the other hand those of the display observation window at a certain angle from the plane of the keypad is inclined in order to achieve better readability when using such a calculator as a Table-top unit used For such different types of computers, due to the inventive Measures use one and the same substrate.

Somit kann ein Substrattyp mit einer einzigen Herstellungsanlage und in wesentlich größerer Stückzahl als die herkömmlicherweise individuellen Substrate für jeden einzelnen Rechnertyp hergestellt werden, so daß sich insgesamt eine Kostensenkung ergibt. Denn bei Massenherstellungsmethoden geht die hergestellte Stückzahl beträchtlich in den Stückpreis ein.Thus, one type of substrate can be produced with a single production facility and in significantly larger numbers than the conventional individual substrates are manufactured for each individual type of computer, see above that overall there is a cost reduction. Because with mass production methods, the manufactured one goes The number of items is a considerable factor in the unit price.

Durch die erfindungsgemäßen Maßnahmen ist auch mit sehr einfachen Mitteln die Möglichkeit gegeben, den die Anzeigevorrichtung tragenden Endabschnitt des Substrates im bereits zusammengebauten Rechner in seiner Lage gegenüber dem Anzeigebeobachtungsfenster verstellbar zu machen. Damit kann dem Benutzer eines solchen Kleinrechners die Möglichkeit gegeben werden, je nach seinen individuellen Wünschen die Anzeigevorrichtung unter dem Anzeigebeobachtungsfenster mehr oder weniger schräg zu stellen, um je nach seinen Körperverhältnissen und Gewohnheiten, den Rechner zu halten oder in weiterem oder kürzerem Abstand vor sich auf einem Tisch liegend zu bedienen, die Ablesbarkeit optimal einstellen zu können.The measures according to the invention also provide the possibility with very simple means, the the end portion of the substrate carrying the display device in the already assembled computer in FIG to make its position relative to the display observation window adjustable. This allows the user such a small computer can be given the option, depending on its individual needs To put the display device under the display observation window more or less inclined, depending on the his body conditions and habits to hold the calculator or in further or shorter To operate at a distance from lying on a table, to be able to optimally adjust the readability.

Vorteilhafte Weiterbildungen des neuen Kleinrechners sind in den Unteransprüchen angegeben.Advantageous further developments of the new small computer are given in the subclaims.

Es sei noch erwähnt, daß es aus der GB-PS 10 48 021 bekannt ist, mehrere gleichgroße Mikroschaltungselemente parallel nebeneinander auf einem flexiblen Substrat anzuordnen und dann das Substrat mit den Mikroschaltungselementen ziehharmonikaartig zu falten, um die Mikroschaltungselemente und das Substrat auf möglichst kleinem Raum unterbringen zu können.It should also be mentioned that it is known from GB-PS 10 48 021, several microcircuit elements of the same size to be arranged in parallel next to each other on a flexible substrate and then the substrate with the To fold microcircuit elements in an accordion manner around the microcircuit elements and the substrate to be able to accommodate in the smallest possible space.

Das flexible Substrat gibt dabei die Möglichkeit, einerseits den Zusammenbau der Gesamtschaltung relativ einfach zu machen und andererseits bei erforderlichen Reparaturen die einzelnen Mikroschaltungselemente der Gesam'schaltung leicht zugänglichThe flexible substrate enables the assembly of the entire circuit on the one hand relatively easy to make and, on the other hand, the individual microcircuit elements when repairs are required easily accessible to the entire circuit
