Description

Elektronische Taxameter bestehen in der Regel heute mindestens aus einem elektronischen Rechenteil, einem Datenspeicher, einem Bedienteil, einem Systemspeicher sowie einem Zeitgeber. Innerhalb des Datenspeichers ist es möglich, in einem Tageszeitspeicher jeweils die aktuelle Tageszeit zu speichern, die unter Zuhilfenahme des Zeitgebers errechnet wird und die zur Anzeige gebracht werden kann, insbesondere dann, wenn der Taxameter nicht in Funktion ist, wenn also die Anzeige nicht zur Anzeige des laufenden Fahrpreises benötigt wird.Electronic taximeters generally today consist of at least one electronic computing part, a data memory, a control unit, a system memory and a timer. Within the data memory, it is possible to save the current time of day in a time-of-day memory, which is calculated with the help of the timer and which can be displayed, especially if the taximeter is not functioning, i.e. if the display is not for display of the current fare is required.

Der Tageszeitspeicher kann aber auch zu diversen anderen Schaltzwecken benutzt werden. Z.B. ist es möglich, in Abhängigkeit von der Tageszeit Umschaltungen in der Tarifstruktur des Taxameters vorzunehmen, z.B. von einer Tageszeittaxe auf eine Nachttaxe umzuschalten. Selbstverständlich ist es erwünscht, dass sowohl die Anzeige der Tageszeit richtig erfolgt als auch dass die Umschaltung des Taxameters von einer Taxe auf eine andere genau zum richtigen Zeitpunkt vorgenommen wird. Andererseits ist es nicht auszuschliessen, dass auch mit einem sehr genauen Zeitgeber über einen längeren Zeitraum gesehen der Inhalt des Tageszeitspeichers von der tatsächlichen Tageszeit abweicht, so dass eine Korrektur des Inhalts des Tageszeitspeichers wünschenswert ist.The time of day memory can also be used for various other switching purposes. E.g. Depending on the time of day, it is possible to make changes in the tariff structure of the taximeter, e.g. to switch from a daytime tax to a nighttime tax. Of course, it is desirable that both the time of day is displayed correctly and that the taximeter is switched from one rate to another at exactly the right time. On the other hand, it cannot be ruled out that even with a very precise timer, the content of the time of day memory deviates from the actual time of day, so that a correction of the content of the time of day memory is desirable.

Da andererseits Taxameter aber nicht manipulierbar sein dürfen, muss die Wirkungsweise des Zeitgebers in Verbindung mit dem Tageszeitspeicher normalerweise plombiert sein, d.h. ein Richten des Tageszeitspeichers darf bei gesetzter Plombe nicht durchgeführt werden. Eine solche starre Regelung verhindert aber auch eine geringfügige Korrektur des Tageszeitspeichers, um Zeitabweichungen auszugleichen.On the other hand, since taximeters must not be manipulable, the mode of operation of the timer in connection with the time of day storage must normally be sealed, i.e. the time of day memory must not be adjusted when the seal is set. However, such a rigid regulation also prevents a slight correction of the time of day storage in order to compensate for time deviations.

Aufgabe der Erfindung ist es demgegenüber, eine Methode anzugeben, durch die ein Richten des Tageszeitspeichers trotz seiner Plombierung möglich sein soll, die aber eine bewusste Manipulierung ausschliesst.In contrast, the object of the invention is to provide a method by which it is possible to straighten the time-of-day memory despite its sealing, but which excludes deliberate manipulation.

Die Erfindung geht aus von einem Taxameter mit einem elektronischen Rechenteil, einem Datenspeicher, einem Bedienteil, einem Systemspeicher sowie einem Zeitgeber, bei dem die aktuelle Tageszeit in einem Tageszeitspeicher gespeichert zu Anzeige- und Schaltzwecken zur Verfügung steht und ist dadurch gekennzeichnet, dass zur Korrektur des Tageszeitspeichers in bestimmten Funktionsstellungen des Taxameters eine erste Taste ein Vorwärtsrichten des Tageszeitspeichers ermöglicht im Rahmen einer begrenzten Zeitvorgabe durch einen ersten Hilfszeitspeicher, dass eine zweite Taste ein Rückwärtsrichten des Tageszeitspeichers im gleichen Rahmen ermöglicht, vorausgesetzt, dass ein zweiter Hilfszeitspeicher, der bei jeder Betätigung der ersten und/oder der zweiten Taste geladen wird und durch den Zeitgeber kontinuierlich entleert wird, den Nullzustand erreicht hat.The invention relates to a taximeter with an electronic computing part, a data memory, a control unit, a system memory and a timer, in which the current time of day stored in a time of day memory is available for display and switching purposes and is characterized in that for correcting the Time memory in certain functional positions of the taximeter, a first button to forward the day time memory enables a second button to reverse the day time memory within the scope of a limited time setting, provided that a second auxiliary time memory that is activated each time the first one is pressed and / or the second button is loaded and is continuously emptied by the timer that has reached the zero state.

Die erfindungsgemässe Korrekturmöglichkeit für den Tageszeitspeicher kann dabei abhängig gemacht sein von dem Plombieren des Gerätes, d.h. wenn die Plombe nicht gesetzt ist, kann ein beliebiges Vorwärts- und Rückwärtsrichten des Tageszeitspeichers möglich sein, was zur Inbetriebnahme des Gerätes unbedingt notwendig ist.The possibility of correction for the time of day storage according to the invention can be made dependent on the sealing of the device, i.e. If the seal is not set, it can be possible to move the time memory forward and backward as required, which is absolutely necessary for commissioning the device.

Im übrigen ist das Uhrzeitrichten nur möglich, wenn der Taxameter in seiner Frei-Stellung ist. Wahlweise kann es zusätzlich noch in Abhängigkeit gebracht werden von der Betätigung eines Schlüsselschalters oder einer sonstigen, nicht jedermann zugänglichen Taste, die vorgesehen ist, beispielsweise für den Taxibesitzer, um Zählerstände auszulesen, so dass im Zusammenhang mit dem Auslesen der Zählerstände durch eine hierfür besonders autorisierte Person auch das Korrigieren des Zeitspeichers vorgenommen werden kann.In addition, time-of-day adjustment is only possible if the taximeter is in its free position. Optionally, it can also be made dependent on the actuation of a key switch or another button that is not accessible to everyone and is provided, for example for the taxi owner, to read meter readings, so that in connection with reading the meter readings by a person who is specially authorized to do so Person can also correct the time memory.

Die Erfindung sei nun im Zusammenhang mit den beiliegenden Zeichnungen im einzelnen erläutert. In diesen Zeichnungen zeigt

  • Fig. 1 eine Frontansicht des Gerätes,
  • Fig. 2 ein prinzipielles Schaltbild der Elektronik des Gerätes,
  • Fig. 3 das erfindungsgemässe Korrekturverfahren für den Zeitspeicher.
The invention will now be explained in connection with the accompanying drawings. In these drawings shows
  • 1 is a front view of the device,
  • 2 is a basic circuit diagram of the electronics of the device,
  • 3 shows the correction method for the time memory according to the invention.

Wie die Frontansicht gemäss Fig. 1 des Taxameters erkennen lässt, ist dieser Taxameter mit einem Gehäuse G ausgerüstet, das an seiner unteren Seite eine Tastenleiste TL aufweist. In dieser Tastenleiste befinden sich eine Anzahl von Bedientasten, beispielsweise die Tasten T1 bis T4. Zusätzlich kann in dieser Tastenleiste TL noch ein Schlüsselschalter SK angeordnet sein, der mittels eines Schlüssels nur einer hierfür speziell autorisierten Person zugänglich ist, um bestimmte Ablesevorgänge, beispielsweise der Kontrollzähler usw. durchführen zu können. Selbstverständlich kann dieser Schlüsselschalter SK aber auch an irgendeiner beliebigen anderen Stelle des Gehäuses angeordnet sein, auch in Form einer besonderen blockierbaren Taste.As can be seen from the front view according to FIG. 1 of the taximeter, this taximeter is equipped with a housing G which has a key strip TL on its lower side. There are a number of operating keys in this key bar, for example the keys T1 to T4. In addition, a key switch SK can also be arranged in this key strip TL, which key can only be accessed by a person specially authorized for this purpose in order to be able to carry out certain reading processes, for example the control counter, etc. Of course, this key switch SK can also be arranged at any other point on the housing, also in the form of a special lockable button.

Unterhalb der Tastenleiste TL ist das Gehäuse G mit drei Vorsprüngen LV, MV und RV versehen. Der mittlere Vorsprung MV dient der Anbringung eines Typenschildes, die beiden linken und rechten Vorsprünge LV und RV dienen der Plombierung einerseits des Gehäuses oder des Gerätes mittels einer Plombierung FK, andererseits speziell des Tarifes durch eine Plombierschraube PK.Below the key strip TL, the housing G is provided with three projections LV, MV and RV. The middle projection MV is used to attach a type plate, the two left and right projections LV and RV are used to seal the housing or the device by means of a seal FK, and especially the tariff by a sealing screw PK.

Oberhalb der Tastenleiste TL ist das Gehäuse mit einem durchsichtigen Anzeigefeld AF ausgerüstet, das mit einem Frontschriftblatt FS abgedeckt ist. In dem Anzeigefeld sind mehrere Anzeigefenster AF1 bis AF5 vorgesehen. Hiervon dienen die grösseren Anzeigefenster AF1 bis AF2 der Anzeige des Fahrpreises und des Zuschlages, die kleineren Anzeigefenster AF3 bis AF5 dienen der Anzeige der Taxzustände.Above the key bar TL, the housing is equipped with a transparent display field AF, which is covered with a front document FS. Several display windows AF1 to AF5 are provided in the display field. Of these, the larger display windows AF1 to AF2 serve to display the fare and the surcharge, the smaller display windows AF3 to AF5 serve to display the taxi status.

In den Anzeigefenstern AF1 und AF2 werden, wie bereits erwähnt, während des Betriebes des Gerätes einerseits der Fahrpreis und andererseits der Zuschlag angezeigt. Wenn das Gerät nicht in Betrieb ist, wenn es sich also beispielsweise funktionsmässig in der sog. «Frei»-Stellung befindet, können in den beiden Anzeigefenstern AF1 und AF2 andere Daten angezeigt werden, z.B. die Kontrollzählerwerte, aber auch beispielsweise die aktuelle Tageszeit und ein Datum oder dergl. Die Anzeigefelder AF3 bis AF5 sind jeweils umrahmt von Leuchtdioden LED, mit deren Hilfe es möglich ist, die verschiedenen Funktionszustände des Gerätes anzuzeigen, die durch eine Beschriftung in diesen Anzeigefeldern AF3 bis AF5 kenntlich gemacht werden.As already mentioned, the display windows AF1 and AF2 show, on the one hand, the fare and, on the other hand, the surcharge during the operation of the device. If the device is not in operation, for example if it is radio In the so-called “free” position, other data can be displayed in the two display windows AF1 and AF2, e.g. the control counter values, but also e.g. the current time of day and a date or the like. The display fields AF3 to AF5 are each framed by Light-emitting diodes LED, with the aid of which it is possible to display the various functional states of the device, which are identified by labeling in these display fields AF3 to AF5.

Fig. 2 zeigt im wesentlichen die Haupthardwarekomponenten des Taxameters. Ein Mikroprozessor MC ist das elektronische Rechenteil. Der Mikroprozessor MC ist über Verstärkungs- und Multiplexmittel VM mit der Anzeige AZ verbunden. Die Anzeige AZ besteht, wie bekannt, aus einzelnen 7-Segment-Anzeigeelementen, die hinter den Anzeigefenstern AF1 und AF2 gemäss Fig. 1 erscheinen.Fig. 2 essentially shows the main hardware components of the taximeter. A microprocessor MC is the electronic computing part. The microprocessor MC is connected to the display AZ via amplification and multiplexing means VM. As is known, the display AZ consists of individual 7-segment display elements which appear behind the display windows AF1 and AF2 according to FIG. 1.

Zu den wesentlichsten Hardwarekomponenten der Elektronik gehören auch ein Datenspeicher RAM, ein Tarifspeicher TPROM und ein oder zwei Systemspeicher EPROM1 und EPROM2. Die Systemspeicher EPROM1 und EPROM2 nehmen das gesamte Programm des Taxameters auf, wobei wahlweise selbstverständlich bei einem einfachen Gerät auch ein einzelner Systemspeicher EPROM1 vollkommen ausreichend ist. Der Datenspeicher RAM übernimmt alle während der Ermittlung des Fahrpreises errechneten Zwischenwerte und auch etwaige Prüf- und Kontrollwerte, die mit einer Batterie Bt1 abgesichert sind. Der Tarifspeicher TPROM enthält die unterschiedlichsten Tarifdaten, die durch die Tarifbestimmungen in den einzelnen Kommunen und Ländern vorgegeben sind. Was den Tageszeitspeicher TZ anbetrifft, so kann dieser Bestandteil des Mikroprozessors bzw. Rechenteils MC sein, da dieser auch einen Zeitgeber Z1 hat. Dies hat jedoch zur Folge, dass bei nicht eingeschaltetem Taxameter das Rechenteil MC ständig an Spannung liegen muss und damit die Fahrzeugbatterie dauernd belastet. Zweckmässiger ist es daher, einen besonderen Uhrenbaustein CL vorzusehen, wie er für Uhren, Radiowecker u. dgl. üblich ist, in dem der Tageszeitspeicher TZ vorgesehen ist. Der Uhrenbaustein CL ist noch mit einer Batterie Bt2 gesichert und mit einem Zeitgeber Z2 versehen.The most important hardware components in electronics also include a data memory RAM, a tariff memory TPROM and one or two system memories EPROM1 and EPROM2. The system memories EPROM1 and EPROM2 record the entire program of the taximeter, whereby, of course, with a simple device, a single system memory EPROM1 is of course completely sufficient. The data memory RAM takes over all intermediate values calculated during the determination of the fare and also any test and control values which are secured with a battery Bt1. The tariff memory TPROM contains a wide variety of tariff data, which are specified by the tariff regulations in the individual municipalities and countries. As far as the time-of-day memory TZ is concerned, this can be part of the microprocessor or computing part MC, since it also has a timer Z1. However, this has the consequence that when the taximeter is not switched on, the computing part MC must be constantly live and thus continuously load the vehicle battery. It is therefore more expedient to provide a special clock module CL, such as that used for clocks, clock radios and the like. The like. It is common in which the time of day storage TZ is provided. The clock module CL is still secured with a battery Bt2 and provided with a timer Z2.

Als Bedienteil des Gerätes dient die Tastenleiste TL mit ihren Tasten T1 bis T4, die jeweils auf Kontakte K1 bis K4 einwirken. Von diesen Tasten dient beispielsweise die Taste T1 der Vorwärtsschaltung von «Frei» nach «Taxe 1 » usw., die Taste T2 der Rückwärtsschaltung von «Kasse» nach «Taxe 1 oder dergl. Die Tasten T3 und T4 können genau wie T1 und T2 per Programm beliebige Funktionen haben, z.B. kann T3 bei in Betrieb befindlichem Gerät den Zuschlag betätigen. Insbesondere in der «Frei»-Stellung können den Tasten T3 und T4 beliebige Sonderfunktionen, wie z.B. die Anzeige der Kontrollspeicher, u.dgl. zugeordnet werden.The button bar TL with its buttons T1 to T4, which act on contacts K1 to K4, serves as the operating part of the device. Of these keys, for example, the T1 key is used to switch from "free" to "Taxe 1", etc., the T2 key is used to switch back from "cashier" to "Taxe 1" or the like. The T3 and T4 keys can be used in the same way as T1 and T2 Program have any functions, e.g. T3 can operate the surcharge when the device is in operation. In the «free» position in particular, the buttons T3 and T4 can be used for any special functions, such as the display of the control memory, etc. be assigned.

Die Plombierschraube PK betätigt einen Kontakt K5, der geschlossen oder offen ist, wenn das Gerät fertig plombiert ist. Hierdurch werden gleichzeitig die Zeitgeber Z1 und Z2 eingeschaltet, die Zeitimpulse erzeugen. Der Schlüsselschalter SK betätigt einen Kontakt K6, wenn der Schlüssel eingesteckt und herumgedreht ist. Alle Kontakte K1 bis K6 zusammen sind an eine Codiermatrix C angeschlossen, in der die Tastensignale codiert aufbereitet werden und über Eingangsgatter Ga auch auf die Bus-Leitungen B1 und B2 gegeben werden, wenn dies vom Programm angefordert wird.The sealing screw PK actuates a contact K5, which is closed or open when the device is completely sealed. As a result, the timers Z1 and Z2 are switched on, which generate time pulses. The key switch SK actuates a contact K6 when the key is inserted and turned around. All contacts K1 to K6 together are connected to a coding matrix C, in which the key signals are processed in coded form and are also passed to bus lines B1 and B2 via input gates Ga when the program requests this.

Innerhalb des Uhrenbausteins CL oder des Rechenteiles MC ist ein Speicher der Tageszeitspeicher TZ, der durch den Zeitgeber Z1 oder Z2 gesteuert nach entsprechender Impulsreduzierung jeweils die aktuelle Tageszeit speichert und für die Anzeige AZ zur Verfügung stellt. Zwei weitere Speicher sind Hilfszeitspeicher A und B, die für die Korrektur des Tageszeitspeichers TZ benötigt werden und die auch je nach Bedarf entweder Bestandteil des Rechenteiles MC oder des Uhrenbausteins CL sind. Der Hilfszeitspeicher B wird, wenn er geladen wird, zusammen mit dem Tageszeitspeicher TZ von dem Zeitgeber Z1 oder Z2 in Rückwärtsrichtung auf Null gestellt, wenn der Tageszeitspeicher TZ fortgeschaltet wird.Within the clock module CL or the computing part MC is a memory of the time of day memory TZ which, controlled by the timer Z1 or Z2, stores the current time of day after a corresponding pulse reduction and makes it available for the display AZ. Two other memories are auxiliary time memories A and B, which are required for the correction of the time of day memory TZ and which, depending on requirements, are either part of the computing part MC or of the clock module CL. The auxiliary time memory B, when loaded, is set together with the time of day memory TZ by the timer Z1 or Z2 in the reverse direction to zero when the time of day memory TZ is advanced.

Die Möglichkeiten der Korrektur des Tageszeitspeichers TZ seien nun im Zusammenhang insbesondere mit der Fig. 3 im einzelnen näher beschrieben. Innerhalb des Taxameterprogrämmes 20, welches in dem Systemspeicher EPROM1 bzw. EPROM 2 gespeichert ist, ist ein besonderer Programmteil dem Uhrzeitrichten 22 zugeordnet. Diese Programmroutine wird jedoch nur angerufen, wenn der Taxameter in der «Frei»-Stellung 21 ist, der Plombierkontakt PK/K5, 23 geschlossen und der Kontakt K6 durch den Schlüsselschalter SK betätigt worden ist, d.h. nur wenn der Schlüsselschalter SK, 24 bedient wurde, können irgendwelche Eingriffe in den Fortschaltablauf des Tageszeitspeichers TZ durch MC oder CL vorgenommen werden. Es ist selbstverständlich, dass man auf diese zusätzliche Sicherheitsmassnahme über den Schlüsselschalter SK verzichten kann, wenn diese Form der Sicherung nicht gewünscht wird. In aller Regel wird es jedoch zweckmässig sein, die Durchführung der Prüfroutine «Uhrzeitrichten» 22 abhängig zu machen von der Betätigung des Schlüsselschalters SK.The possibilities for correcting the time of day memory TZ will now be described in more detail in connection with FIG. 3 in particular. Within the taximeter program 20, which is stored in the system memory EPROM1 or EPROM 2, a special program part is assigned to the clock time 22. However, this program routine is only called when the taximeter is in the "free" position 21, the sealing contact PK / K5, 23 is closed and the contact K6 has been actuated by the key switch SK, i.e. only when the key switch SK, 24 has been operated can any interventions in the sequencing sequence of the day time memory TZ be carried out by MC or CL. It goes without saying that you can do without this additional safety measure using the SK key switch if this form of security is not desired. As a rule, however, it will be expedient to make the execution of the “time-of-day” check routine 22 dependent on the actuation of the key switch SK.

Wird innerhalb der Prüfroutine «Uhrzeitrichten» 22 der Plombierkontakt PK/K5, 23 «offen» festgestellt, d.h. also ist die Plombe nicht gesetzt, dann kann der Tageszeitspeicher TZ beliebig vorwärts und rückwärts gerichtet werden (25). Dies ist zusätzlich abhängig von der Betätigung entweder der Taste T3 oder der Taste T4. Dabei ist die Taste T4 dem Vorwärtsrichten zugeordnet und die Taste T3 dem Rückwärtsrichten. Ist also der Plombenkontakt PK/K5, 23 nicht gesetzt, wird aber die Taste T3 oder die Taste T4 betätigt, dann erfolgt ein Vorwärts- oder Rückwärtsrichten des Tageszeitspeichers TZ. Diese Massnahme wird insbesondere dann von Wichtigkeit sein, wenn ein Gerät neu in Betrieb genommen wird oder nachdem irgendwelche Reparaturen, Tarifumstellungen oder dergl. durchgeführt worden sind.If the sealing contact PK / K5, 23 is detected as "open" within the "Routine time" check routine 22, ie if the seal is not set, the time of day memory TZ can be directed forwards and backwards as desired (25). This also depends on the actuation of either the T3 key or the T4 key. The key T4 is assigned to the forward direction and the key T3 to the reverse direction. If the seal contact PK / K5, 23 is not set, but if the key T3 or the key T4 is actuated, the time-of-day memory TZ is directed forward or backward. This measure will be particularly important if a device is put into operation again or after ir any repairs, tariff changes or the like have been carried out.

Ist der Schlüsselkontakt SK/K6 nicht betätigt, dann wird zunächst die Taste T4 (26) abgefragt, ob der Kontakt K4 geschlossen ist. Ist der Kontakt K4 geschlossen gewesen, also die Taste T4 betätigt, dann wird zunächst der Hilfszeitspeicher B (27) abgefragt, ob die darin vorgegebene Zeit abgelaufen ist. Der Hilfszeitspeicher B hat die Funktion, innerhalb eines bestimmten Zeitraumes von beispielsweise 5 oder 6 Tagen einen Korrekturvorgang auszuschliessen, so dass das Richten der Uhrzeit jeweils nur in den Abständen erfolgen kann, in denen beispielsweise auch die Kontrollspeicher abgefragt werden und dergl. Der Zeitraum, der hier vorgegeben wird, hängt natürlich von den organisatorischen Gepflogenheiten des jeweiligen Taxi-Unternehmens ab.If the key contact SK / K6 is not actuated, the button T4 (26) is first queried as to whether the contact K4 is closed. If the contact K4 was closed, that is to say the key T4 was pressed, the auxiliary time memory B (27) is first queried as to whether the time specified therein has expired. The auxiliary time memory B has the function of excluding a correction process within a certain period of time, for example 5 or 6 days, so that the time can only be adjusted at intervals in which, for example, the control memory is also queried and the like is specified here, of course, depends on the organizational practices of the respective taxi company.

Ist der Hilfszeitspeicher B nicht abgelaufen, dann kann auch keine Korrektur der Uhrzeit erfolgen. Nur wenn der Hilfszeitspeicher B abgelaufen ist, wird in einen Hilfszeitspeicher A ein bestimmter, begrenzter Zeitbereich eingespeichert (28), beispielsweise von höchstens 5 Min., denn höher kann die Zeitdifferenz zwischen der tatsächlichen, im Tageszeitspeicher TZ gespeicherten Zeit und der aktuellen Tageszeit bei einem quarzgesteuerten Zeitgeber Z1 oder Z2 nicht sein. Danach kann das Vorwärtsrichten durch eine entsprechend lange Betätigung der Taste T4 durchgeführt werden (29), wobei der Tageszeitspeicher TZ durch Eingabe von zusätzlichen Impulsen fortgeschaltet wird, bis durch das Loslassen der Taste T4 angezeigt wird, dass jetzt die richtige Tageszeit erreicht ist. Nach Ablauf dieses Richtvorganges wird wiederum der Hilfszeitspeicher B geladen (30), d.h. innerhalb des in diesem Zeitspeicher gespeicherten Zeitraumes von beispielsweise 5 oder 6 Tagen kann eine erneute Uhrzeitkorrektur bei gesetzter Plombierschraube PK nicht erfolgen.If the auxiliary time memory B has not expired, the time cannot be corrected either. Only when the auxiliary time memory B has expired is a specific, limited time range stored in an auxiliary time memory A (28), for example of at most 5 minutes, because the time difference between the actual time stored in the day time memory TZ and the current time of day can be higher quartz controlled timer Z1 or Z2 not be. The forward straightening can then be carried out by pressing the T4 button for a corresponding length of time (29), the time of day memory TZ being continued by entering additional pulses until the T4 button is released to indicate that the correct time of day has now been reached. After this straightening process has ended, the auxiliary time memory B is again loaded (30), i.e. Within the time period of 5 or 6 days stored in this time memory, for example, a new time correction cannot be carried out with the sealing screw PK set.

Analog verhält es sich in den Fällen, in denen nicht die Taste T4 für einen Vorwärtsrichtvorgang geschlossen ist, sondern die Taste T3 für einen Rückwärtsrichtvorgang, mit dem einzigen Unterschied, dass hier eben nicht ein Fortschalten des Tageszeitspeichers TZ, sondern ein Rückwärtsrichten erfolgt, solange wie die Taste T3 gedrückt ist und im Rahmen dessen, was durch den Hilfszeitspeicher A vorgegeben ist (31 bis 34).The situation is similar in cases in which it is not the T4 button that is closed for a forward straightening process, but the T3 button for a backward straightening process, with the only difference that the time of day memory TZ is not stepped forward, but is reversed as long as the button T3 is pressed and within the scope of what is specified by the auxiliary time memory A (31 to 34).

Um zu verhindern, dass beim Vorwärts- oder Rückwärtsrichten ein Überlaufen der richtigen Position des Tageszeitspeichers erfolgt, indem die Taste T4 oder T3 zulange gedrückt gehalten wird, kann die Einrichtung selbstverständlich so programmiert sein, dass für jeden Fortschaltvorgang um eine Einheit die Taste T3 bzw. T4 jeweils einmal zu betätigen ist. Dabei muss dann allerdings Sorge dafür getragen werden, dass die Zeitspeicher A und B jeweils nur einmal geladen werden.In order to prevent the correct position of the time of day memory from overflowing during forward or backward direction by keeping the T4 or T3 button pressed for too long, the device can of course be programmed in such a way that the T3 or T4 must be operated once. Care must then be taken to ensure that time memories A and B are only loaded once.

Claims (4)

1. Taximeter having an electronic calculating part (MC), a data store (RAM), an input part (TL) and a system store (EPROM1, EPROM2) as well as a time pulse generator (Z1 or Z2), the actual day time being stored in a day time store (TZ) and being available for indicating and switching purposes, characterized in that for correcting the day time store (TZ) in a specific functional position of the taximeter a first key (T4) allows for correcting the day time store in forward direction within a limited time extent by means of a first auxiliary store (A), in that a second key (T3) allows for correcting the day time store (TZ) in reverse direction to the same extent, provided that a second auxiliary store (B) has reached zero position, which auxiliary store (B) is loaded on each actuation of the first and/or the second key (T3 or T4) and is continuously reset by the time pulse generator (Z1 or Z2).
2. Taximeter according to Claim 1, characterized in that the functional position of the taximeter in which a time correction is admissible is the «For Hire» position.
