Abstract

A computer system has a plurality of independent input peripheral devices which create a more user-friendly and versatile way to interact with the computer. An alphanumeric keyboard, a numeric keyboard, a function keyboard and a Mouse pointing device all communicate input data to the computer. The computer is simultaneously responsive to the data communicated by all of the input peripherals. The user may select one or more of the input peripherals to operate simultaneously to effect efficient data input. The input peripherals may be connected to the computer with cords, or may be operated in a cordless mode. The computer maps the data generated by the three keyboards into the same symbol table so that it need not determine where the data originated. Three of the input peripherals are disposable into cradles defined in a housing, while the alphanumeric keyboard is disposable into a cavity defined within the housing. An ejector mechanism discharges the alphanumeric keyboard from the cavity when a door of the cavity is opened.

Claims

1. An apparatus for processing information comprising:

first keyboard means manipulated by a user for selectively producing a first input data;

second keyboard means manipulated by a user for selectively producing second input data;

third keyboard means manipulated by a user for selectively producing third input data;

electronic mouse means manipulated by a user for selectively producing fourth input data;

data processing means, responsive to said first, second, third and fourth input data simultaneously, for processing said input data; and

a housing having means defining a plurality of indentations and means defining a cavity;

said first keyboard means being selectively disposed in said cavity and said second and third keyboard means and said electronic mouse means being selectively disposed in at least one of said plurality of indentations, said housing further including;

means for selectively sealing said cavity when said first keyboard means is disposed in said cavity; and

ejector means, coupled to said sealing means, for ejecting said first keyboard means from said cavity when said cavity is unsealed.

2. An apparatus as in claim 1 wherein said ejector means includes:

an ejecting member rectilinearly slidable through said cavity between at least a first position and a second position, said ejecting member sliding to said first position when said first keyboard means is disposed in said cavity;

biasing means for biasing said ejecting member towards said second position, said first keyboard means being ejected from said cavity as said ejecting member slides from said first position to said second position;

latching means for selectively retaining said first keyboard means in a predetermined position within said cavity; and

actuating means for causing said latching means to release said first keyboard means in response to the unsealing of said cavity by said sealing means.

3. An apparatus as in claim 2 wherein:

said first keyboard means includes means for defining a cavity therein; and

said latching means includes engaging means for selectively engaging with said cavity of said first keyboard means.

4. An apparatus as in claim 1 further including:

means for producing an electrical signal; and

means, disposed on said ejector means, for coupling said electrical signal to said first keyboard means.
