Introduction

GB/T 17971 Information Technology Equipment (ITE) defines a framework for a keyboard layout. Keyboard functions respectively corresponding to the four Complete physical keyboard.

This standard keyboard by dividing different functional areas, and orient design provides users with a unified, open interface. The primary standard to accommodate today's task is to use the keyboard application system requires a variety of character sets, the main solution is for each alphanumeric key area Assign one or more graphic characters or control functions.

Keyboard layouts for text and office IT systems Part 1. General rules governing keyboard layouts

1 Scope

GB/T 17971 specifies the various characteristics of information technology equipment (ITE) used by the keyboard. For example the following ITE.

Computer a) having an alphanumeric keypad, workstations, computer terminals, visual display device (VDT), typewriter.

b) has a numeric keypad calculators, telephones, automatic teller machines (ATM).

GB/T 17971-defined keyboard is the usual linear keyboard. It is divided into several areas in physics, each district is divided into several partitions, partition Placed within the various keys.

This section GB/T 17971 specifies the shape of the keyboard area and relative placement. This section contains the key spacing and physical characteristics, that positioning principle characters and symbols.

This section provides information technology equipment (ITE) applications on the numeric keypad, alphanumeric keyboard, or both keyboard composite keyboard (with Hereinafter referred to as "composite keyboard") key numbering system.

This section provides the information technology equipment (ITE) applications on the numeric keypad, alphanumeric keyboard, or composite characters and symbols keyboard row Column rules. This section applies to a different language, but the main instruction applies to left to right, top to bottom of the written language.

The main layout of the alphanumeric partition established in accordance with national standards and national idiom. Layout Distribution Guide reference GB/T 17971.2.

Supplementary layout reference GB/T 17971.3.

This section defines the relevant characteristics of the interface 1 in Figure 1.

GB/T 17971 specifies the key (key graphic characters and control function keys) the function assignment. According to usage, given the graphic character and control functions common name. In general, we do not want the keyboard to produce encoded control function, however, data exchange, for a Control function key operation likely to trigger a number of coded control functions.

The Effect keyboard state of the keys by the GB/T 17971 other parts of the regulations.
