Abstract

The keyboard of such as a cash register is constructed using two types of push button operated keys, namely those having a long stroke Ä4Ü and those having a short stroke Ä5Ü. Both keys are of a lever Ä9Ü type that are shaped at one end to act as a pivot point and have formed stops Ä16Ü that limit the range of movement. The lever and push button are integrated into a single unit. The tips of the key levers have a switch pad Ä17Ü that engages the projection on a circuit mat Ä18Ü when the push button is operated.

Description

Die Erfindung betrifft ein Tastenfeld für Verkaufs- und Registrierkassen nach dem Oberbegriff des Anspruchs 1.The invention relates to a keypad for sales and cash registers according to the preamble of claim 1.

Ein derartiges Tastenfeld befindet sich beispielsweise in der seit längerem bekannten Registrierkasse TK 2200 der Firma CASIO ®. Es weist für die festgelegten Tasten mit wichtigen Schaltfunktionen größere Schalthube auf, womit vermieden werden soll, daß diese schon beim leichten Berühren schalten.Such a keypad is, for example, in the CASIO ® cash register TK 2200, which has been known for some time. It has a larger switching stroke for the defined keys with important switching functions, which is to prevent them from switching when touched lightly.

Die Verkaufs- und Registrierkassen werden für die unterschiedlichsten Bedürfnisse gestaltet und es bedarf immer einer konstruktiven Überarbeitung, wenn ungewöhnliche Anordnungen gewünscht werden.The sales and cash registers are designed for a wide variety of needs and a constructive revision is always required if unusual arrangements are desired.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ausgehend von einem gattungsgemäßen Tastenfeld Maßnahmen aufzufinden, mit denen ohne konstruktivem Aufwand jede beliebige Konstellation der Tasten mit Lang- oder Kurzhub erreichbar ist.Proceeding from this, the invention is based on the object, starting from a generic keypad, to find measures with which any constellation of the keys with long or short stroke can be reached without any design effort.

Diese Aufgabe ist mit den im Kennzeichen des Hauptanspruchs genannten Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind mit den Merkmalen der Unteransprüche angegeben.This object is achieved with the features mentioned in the characterizing part of the main claim. Advantageous developments of the invention are specified with the features of the subclaims.

Ein Ausführunsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An exemplary embodiment of the invention is shown in the drawing and is described below.

Fig. 1 zeigt ein Tastenfeld für Verkaufs- oder Registrierkassen mit einem Tastenbereich 2 mit Tasten 3, die als Langhub-Wipptasten 4 ausgeführt sind und mit Tasten, die als Kurzhub-Wipptasten 5 ausgeführt sind.Fig. 1 shows a keypad for cash registers or cash registers with a key area 2 with keys 3, which are designed as long-stroke rocker buttons 4 and with keys, which are designed as short-stroke rocker buttons 5.

Es ist vorgesehen, daß bei einheitlichem Tastenabstand aller Tasten 3 die Kurzhub-Tasten als Wipptaste 5 mit kurzem Tastenhebelarm 7 und langem Schalthebearm 8 und die Langhubtasten als Wipptaste 4 mit langem Tasten- und kurzem Schalthebelarm 7, 8 ausgeführt sind (Fig. 6 und 7), wobei in montiertem Zustand die Taste 3 der Langhub-Wipptaste 4 innerhalb einer Hebelgabelung 9 der jeweils benachbarten Langhub-Wipptaster 4 liegt.It is envisaged that with a uniform key spacing of all keys 3, the short-stroke keys are designed as rocker keys 5 with short key lever arm 7 and long switching lever arm 8 and the long-stroke keys as rocker keys 4 with long key and short switching lever arm 7, 8 (FIGS. 6 and 7 ), whereby in the assembled state the button 3 of the long-stroke rocker button 4 lies within a lever fork 9 of the respectively adjacent long-stroke rocker button 4.

Wie aus Fig. 2 und 3 ersichtlich ist, weisen die beiden Enden der Hebelgabelung 9 sowie die einer Hebelgabelung 10 der Kurzhub-Wipptaste 5 in etwa tonnenförmig ausgebildete Führungszapfen 11 auf, die in Führungsöffnungen 12 eines Führungsrahmens/Gehäuses 13 eingreifen, sowie eine Gleitfläche 14, die dem Bewegungsradius der Wipptasten 4, 5 innerhalb des Führungsrahmens/Gehäuses 13 und eines Trägerbleches 15 angepaßt und in montiertem Zustand eingefedert ist.As can be seen from FIGS. 2 and 3, the two ends of the lever fork 9 and that of a lever fork 10 of the short-stroke rocker button 5 have approximately barrel-shaped guide pins 11, which engage in guide openings 12 of a guide frame / housing 13, and a sliding surface 14 , which is adapted to the range of motion of the rocker buttons 4, 5 within the guide frame / housing 13 and a carrier plate 15 and is compressed in the assembled state.

Zur Tastenhubbegrenzung sieht die Ausführung vor, daß beide Wipptasten 4, 5 im Bereich der Taste 3 Anschlagzapfen 16 aufweisen, die mit einer Unterlage, z. B. einer Kontaktmatte 18 oder dem Trägerblech 15 zusammenwirken.To limit the stroke, the design provides that both rocker buttons 4, 5 have 3 stop pins 16 in the area of the button, which with a pad, for. B. a contact mat 18 or the support plate 15 cooperate.

Die Fig. 2 zeigt auf der linken Seite die Langhub-Wipptasten 4, die dem Tastenfeldbereich mit größerer Wichtigkeit zugehören, und auf der rechten Seite Kurzhub-Wipptasten 5 für normale Funktionen.Fig. 2 shows on the left side the long-stroke rocker buttons 4, which belong to the keypad area with greater importance, and on the right side short-stroke rocker buttons 5 for normal functions.

Fig. 3 zeigt wie erwähnt die Anordnung der Führungszapfen 11 und der Gleitfläche 14 innerhalb des Führungsrahmens/Gehäuses 13 und des Trägerbleches 15. Die Gleitfläche 14 führt die Hebelgabelung 9, 10 spielfrei.3 shows, as mentioned, the arrangement of the guide pins 11 and the sliding surface 14 within the guide frame / housing 13 and the carrier plate 15. The sliding surface 14 guides the lever fork 9, 10 without play.

Fig. 4 zeigt einen Schnitt der Kurzhub-Wipptaste 5 mit Führungszapfen 11, Gleitfläche 14, Taste 3, Anschlagzapfen 16 und einem Schaltnocken 17, der, wie Fig. 2 zeigt, auf eine Kontaktmatte 18 einwirken kann.FIG. 4 shows a section of the short-stroke rocker button 5 with guide pin 11, sliding surface 14, button 3, stop pin 16 and a switching cam 17 which, as shown in FIG. 2, can act on a contact mat 18.

Fig. 5 zeigt den Langhub-Wipptaster 4 mit den gleichen Merkmalen, wobei jedoch die Taste 3 gegenüber dem Schaltnocken 17, ausgehend vom Führungszapfen 11 außen liegt.Fig. 5 shows the long-stroke rocker switch 4 with the same features, but the button 3 is opposite the switch cam 17, starting from the guide pin 11 on the outside.

Fig. 6 und 7 zeigen die beiden Wipptasten 4, 5 in einer schematischen Darstellung mit Anzeige der Tastenhebelarme 7 sowie der Schalthebelarme 8 in bezug auf die Führungszapfen 11, die in montiertem Zustand innerhalb der Führungsöffnungen 12 einen Hebeldrehpunkt 19 bilden.6 and 7 show the two rocker buttons 4, 5 in a schematic representation with display of the button lever arms 7 and the shift lever arms 8 with respect to the guide pins 11, which form a lever pivot point 19 within the guide openings 12 in the assembled state.

Mit der erfindungsgemäßen Ausführung lassen sich beliebige Konstellationen von Bereichen mit Langhubtasten 4 oder Kurzhubtasten 5 zusammenstellen.With the design according to the invention, any constellations of areas with long-stroke keys 4 or short-stroke keys 5 can be put together.

Hierdurch entfällt konstruktiver und fertigungstechnischer Aufwand bei der Anpassung an Kundenanforderungen, da sich die sonstigen Bauteile des Tastenfeldes standardisieren lassen.This eliminates constructional and manufacturing expenditure when adapting to customer requirements, since the other components of the keypad can be standardized.
