Definitions

  • the invention relates to an input device with a keypad for data input into electronic systems.
  • Such an input device is known from WO-A-81 02 349.
  • the values or symbols are numbers or digits from 0 to 9. These can now be completely changed in their order with a random generator, so that an outsider cannot see the actual sequence of the entered values by observing a data entry. However, with each operation there is a completely random arrangement of the individual digits or values, so that the user not only has to concentrate on entering his particular code or data sequence, but also has to search for each individual value of this sequence. The risk of operating errors is correspondingly high.
  • the object is therefore to provide an input device of the type mentioned at the outset for entering data, code sequences, personal identification numbers or the like create, in which neither the observation nor the prepared keys allow conclusions to be drawn about the required sequence of operation of the individual keys when entering certain data, but the risk of operating errors is kept as small as possible.
  • each key can be unlabeled and each key can be assigned a particularly transparent field with a seven-segment display which, when the keypad is activated or activated, displays the value assigned at random or lights up with this value.
  • the transparent field can be provided on the button itself, in particular on its surface or next to it. Misuse is practically impossible, since after activating the input device the user has a complete labeled keypad in front of him and the individual Values assigned to the keys also follow one another in the usual order, with only the beginning of this sequence being at a different point in the entire keypad.
  • a microprocessor can be connected to the random number generator, and the random number generator can be used to relocate the beginning of the ascending row to any key, while the microprocessor assigns the ascending row of values or numbers to the other keys from the other keys.
  • Simple electronic means namely the random number generator and a microprocessor, can thus be used to move the row of values or digits, which in each case remain unchanged, in a simple manner within the keypad.
  • the seven-segment display can be designed as an LCD display. However, all other conceivable and known, controllable seven-segment displays can also be used.
  • the LCD display has the advantage that it has only a very low power requirement, which means that it can even be used with battery-operated input devices.
  • the input device has a time switching element which switches off the display on the keys after a predetermined time after they have been operated. This ensures that the assignment of values to the individual keys is not maintained at least for a short time after data entry and that an observer could possibly enter the data previously observed in the appropriate order.
  • An input device for inputting data, codes, personal identification numbers or the like into electrical systems has a keypad 11, which has a total of ten keys 1 to 10 in the exemplary embodiment.
  • the keys 1 to 9 are arranged in a manner known per se in three rows of three keys each, that is to say in a square, while the tenth key is arranged in the middle below the bottom row of this arrangement.
  • These keys are also assigned the natural numbers from one to nine and the tenth key the number zero, these values or numbers being arranged next to one another in ascending order.
  • the input device has a random generator, not shown in the drawing, assigned to the keypad 11, by means of which the beginning of the row determined by the keys 1 to 9 can be varied and, when the keypad or a specific key of this field is actuated, can be shifted to different keys, whereby the ascending row of the subsequent digits is also shifted and is therefore maintained.
  • the random number generator ensures that the beginning "one" of the ascending row of digits lies on the key 4, so that the last digit nine of this row belongs to the button 3 in this case.
  • FIG. 4 shows an exemplary embodiment in which the key 10 is also involved in the shifting of the number row.
  • the beginning of the row of digits ie the "one”
  • key 9 is marked with "two"
  • key 10 with "three”.
  • the end of the ten-digit row is located at key 7 and is identified by the "zero” in this case. If necessary, one could of course also view this "zero" as the beginning of the row, so that the last digit "nine" then belongs to key 6.
  • the keys 1 to 10 are unlabeled in the exemplary embodiment and each key is assigned a preferably transparent field 12 with a seven-segment display 13.
  • the keypad 11 When the keypad 11 is actuated or activated, the values of all keys 1 to 10 which are randomly provided light up or become visible in a suitable manner. This state is shown in all four figures.
  • the fields 12 could be provided on the respective key itself, in particular on the surface thereof, that is to say to some extent also form the keys in the figures shown.
  • a microprocessor can be connected to the random number generator in order to implement the shifting of the sequence of numbers which remains the same, so that the random number generator can shift the beginning of the ascending number line to any key 1 to 10 is, while this microprocessor assigns the ascending order of the values or digits to the other keys in a constant order, starting from the beginning that lies on different keys.
  • the input device can have a timer which switches off the display on the buttons 1 to 10 after a predetermined time after the end of their operation. If any key or, for example, the zero key or possibly an additional start key, not shown in the exemplary embodiment, is then pressed again for a new data input, the random generator in turn ensures a changed beginning of the row of digits which, however, retains its sequence in itself.
  • the keypad 11 of an input device for entering data in electronic systems is connected to a random generator in such a way that the respective displays, for example seven-segment displays 13, of the individual keys thereof are actuated and in each case the Start of the series of values or digits determined by the keys, for example in the case of a series of digits from zero to nine or one to nine, ie the value zero or one can be varied and can be shifted to different keys when the keypad is actuated.
