  • the present invention generally relates to a combined computer keyboard and calculator and more specifically to such a combination wherein keys of the keyboard can be reassigned for calculator operation.
  • Calculators are well known technical instruments providing various mathematical functions.
  • Personal computers commonly include programs which mimic calculator functions.
  • the versatile personal computer can be switched into a calculator mode using the computer power supply, the computer processor, the computer screen displaying the calculator input and output data, and the computer keyboard to input the calculator data and commands.
  • a separate calculator is not necessary.
  • the provision of a calculator as a program within a personal computer has its disadvantages. It is not possible to perform calculator functions independently, e.g. when the computer is not switched on.
  • the present invention provides a combined computer keyboard and calculator comprising a plurality of keys for inputting data and commands into a computer; calculator processor means for performing calculations; display means for displaying data input to said calculator processor means and calculated data output from said calculator processor means; switch means for reassigning the functions of at least some of said plurality of keys to input data to said calculator processor means; and power supply means for supplying power to said calculator processor means, said display means, said reassignment switch means and said at least some keys. It will be seen that the present invention provides for a compact combined computer keyboard and calculator which allows the independent operation of the calculator within the keyboard arrangement whilst avoiding duplication of keys.
  • the power supply means includes calculator supply means for supplying power to the calculator processor means, the display means, the reassignment switch means, and the keys reassigned for calculator functions at least during a period when no power is supplied by the computer to the keyboard.
  • the calculator power supply means may be arranged to supply power to the calculator processor means, the display means, the reassignment switch means and the reassigned keys even when the keyboard is supplied with power by the computer.
  • the actuation of the reassignment switch means may be arranged to simultaneously actuate the calculator power supply means.
  • a power switch means to switch the power supplied to the calculator processor means, the display means and the keys reassigned to function as input keys for the calculator, from the calculator power supply means to the power supplied by the computer to the keyboard during a period when power is supplied by the computer to the keyboard.

  • the reassignment switch means comprises an additional conversion key in the keyboard.
  • the plurality of keys are laid out in a standard personal computer format with a number key set to one side of the QWERTY key set .
  • the reassignment switch means is arranged to reassign the functions of the keys of the number key set to input data to the calculator processor means.
  • the number keypad is ideally suited for use as the keypad of a calculator.
  • Additional keys can also be provided in addition to the keys normally provided in an IBM (trade mark) compatible computer keyboard for additional calculator functions.
  • some or all of the control keys or cursor locator keys normally provided in an IBM (trade mark) compatible computer keyboard can be reassigned to perform these functions.
  • the calculator power supply means can comprise either at least one battery, at least one solar cell or at least one rechargeable battery. If rechargeable batteries are used, these can be rechargeable from the computer power supply when the computer is switched on.

  • Print Screen/SysRq, Scroll Lock, and Pause/Break keys are provided above these keys, and above these keys is provided the LED displays indicating whether the Num Lock, Caps Lock, or Scroll Lock keys have been pressed.
  • the combined computer keyboard and calculator 1 of this embodiment differs from the conventional IBM AT (trade mark) compatible keyboard in that the keys of the number keypad 5, some of the keys of the control keys 3, and the cursor positioning keys 4 are reassignable from being inputs to the computer in a conventional computer keyboard manner to being inputs for the calculator arrangement within the combined computer keyboard and calculator 1.
  • the Calc/Kboard key can be toggled to enable the control keys 3, the cursor positioning keys 4, and the number keypad 5 to operate as conventional input keys for the computer.

  • the calculator arrangement within the combined computer keyboard and calculator 1 can operate independently of the computer for which the combined computer keyboard and calculator 1 is provided. Space saving is provided by providing for the reassignment of keys between keyboard operation and calculator operation using the Calc/Kboard key.
  • each of the keys of the number keypad, cursor positioning keys 4 and some of the keys of the control keys 3 are labelled with the additional functions which are assigned to them when they are reassigned to operate as inputs for the calculator.

Abstract

L'invention se rapporte à un clavier d'ordinateur et à une calculatrice comprenant une pluralité de touches permettant d'introduire des données et des commandes dans un ordinateur. La calculatrice est pourvue d'un processeur qui sert à effectuer des calculs et d'un dispositif d'affichage permettant d'afficher des données introduites dans le processeur de la calculatrice et des données calculées extraites du processeur de la calculatrice. Un commutateur permet de réaffecter les fonctions d'au moins certaines touches de la pluralité de touches pour introduire des données dans le processeur de la calculatrice. Un dispositif d'alimentation en courant permet d'alimenter en courant le processeur de la calculatrice, le dispositif d'affichage, le commutateur de réaffectation et au moins certaines des touches.
