Abstract

A keyboard for an information processing machine, such as personal computer, is designed so that each alphanumeric key has a rectangular upper surface of 17 mm to 20 mm in width and 20 mm to 25 mm in length. The distance between the upper surfaces of each key is set as 6 to 10 mm. These sizes are bigger than an average key board to allow an easy operation by a user with bigger body. The keyboard has actuators thereon arranged in a conventional keyboard distribution. But, the whole keyboard set is separated into two pieces of equal size and has apparently different configuration. One upper corner of each piece of the keyboard is pivotally connected to one end of a metal arm with a pivot joint. The other ends of two metal arms are connected each other via another pivot joint. This configuration enables a user adjusting the angle and span between the two pieces of a keyboard to maintain a more comfortable position than using conventional keyboard. A document to be typed can be placed between the two pieces of the keyboard of the current application.

Claims

1. A keyboard for a personal computer to enable a user of abnormally large body size use it without any inconvenience is comprised of:

a keyboard which is divided into two pieces of left piece and right piece of equal size, and

pluralities of alphanumeric keys having horizontal length in the range of 17 mm to 20 mm, vertical length in the range of 20 mm to 25 mm and having distance between the upper surfaces of each key in the range of 6 to 10 mm, and

two small pivot joints, one of which is placed on the left upper corner of the right piece and the other is placed on the right upper corner of the left piece of the keyboard respectively, and

two metal arms, one end of each is pivotally connect to one of the pivot joint to adjust the angle between one metal arm and one piece of the keyboard from 15 degree to 345 degree, and

a large pivot joint which connects the other ends of the two metal arms and adjusts the angle between the metal arms from 5 degree to 300 degree, and

a flexible plastic tube one end of which is connected to the large pivot joint and the other end is connected to the main body of a computer.
