Device for setting an electronic clock

The invention relates to a device for adjusting an electronic time display device and in particular a portable electronic watch.

Two different types of setting circles for electronic grandfather or hanging clocks and the like are already known. In one of the known embodiments, the time display device is brought into a certain position, for example 12 o'clock, once every 24 hours. The adjustment is made so one times a day at 12 am, making transition deviations from a Q? Ag turned off by the other kön- new "Such adjustment devices, however, are not suitable for portable electronic watches, since d ^ ese any at all Tageaaeit and, if possible can be set at one or more speeds.

There are also known electronic clocks whose Sinstellungskreis zv / ei switch contains, by pressing either the hour counter or the minute counter is fed with a signal that has a higher frequency than the signal corresponding to the normal speed of the watch owns. The time indicating device can thus with run two different speeds, both of which are greater than normal speed, by your Input of the minute counter or the input of the hour counter fed a frequency of, for example, 1 / sec will.

The disadvantage of such devices is that several switches are operated to set the clock and that one or more different speeds are used for the setting.

The aim of the invention is to avoid these disadvantages. For this purpose, the device according to the invention is for Setting an electronic clock characterized by at least one switch, by means of which the input of the counter of the clock can be switched to a capacitance charged via a resistor, the discharge of which the Introducing or resetting the counter by one unit.

Further details of the invention emerge from the following description, reference being made to the accompanying drawings. On this drawing show:

Fig. 1 and 2 two embodiments of the invention Contraption.

The electronic shown schematically in FIG The clock has a main oscillating circuit 1 that feeds a frequency divider 2. This controls a minute counter and -anseiger 3 »which in turn has an hour meter and indicator 4- feeds.

The adjustment device has two pushbutton actuated Changeover switches 5 and 6, which are in a position determined by a spring when the clock is running normally.

If, for example, the outward display is to be adjusted, the push button of the switch 5 is turned on course pressure exerted. This means that contact 5 & temporarily the circle of the outward counter 3 from the main oscillating circuit 1 is separated and becomes a capacitor fed through a resistor 8 by discharging 7 caused electrical impulse applied. This pulse causes the totalizer and indicator to advance by one unit. ·

If you press this button several times, generates an impulse, which increments the minute digits so that they point to any V / ert can be set. A second contact 5c of the changeover switch 5 interrupts during generation of the impulse by which the numeral is advanced step by step, the normally existing one Connection between the minute counter 3 and the Hour meter 4. This will affect the Hours & nseige by setting the minute display avoided.

To change the hour display, click on similar Proceed in the same way as for setting the minutes by pressing the push button of switch 6. This works in the same way as that of the changeover switch 5j however, only one contact is provided, since the hour counter 4 is not followed by any further counters. The lead pulse is brought about by the discharge of a capacitor 9 charged via a resistor 10. To this An electronic clock can be set step-by-step, with the minute increment as desired. position or the hour setting can be started.

Instead of the two changeover switches 5 and 6, a Switch be provided.

Furthermore, four switches can be used instead of two Changeover switch or two switches may be provided.

The device shown in Fig. 2 has, in addition to the switches 5 and 6, two additional switches provided with push buttons 5Ί 6 ¹ , which allow the step-by-step reset of the minute or hour display. In this way, the hour or minute display can be advanced or reset, depending on which way the desired position can be reached most quickly from the starting position ..

To this. For this purpose, the ^{capacitors 7 'and 9' charged via the resistors 8 1} and 10 'each generate a discharge pulse which is fed to a second input of the counters 3 and 4.

The adjustment device according to the invention is extreme simple, as it does not require an additional oscillating circuit. Furthermore, the user can change the setting by successively actuating the changeover switch at the desired speed.
