Nat

11、ional bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical com- mittees collaborate in fields of mutual inter

12、est. Other international organ- izations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint te

13、chnical committee are circulated to national bodies for vot- ing. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

All standards are subject to revision, and parties to agreements based on this part of ISO/IEC 9995 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of

21、 IEC and IS0 maintain registers of currently valid International Standards. ISO/I EC 9995-l : 1994, information technology - Key- board layouts for text and office systems - Part 1: General principles governing keyboard layouts. ISO/IEC 646:1991, information technology - IS0 7-bit coded character se

22、t for information interchange. ISO/I EC 6937: 1994, Information technology - Coded graphic character set for text communication - Latin alphabet. 4 Definitions For the purposes of this part of ISO/IEC 9995, the definitions given in ISO/IEC 9995-l apply. 5 Arrangement and Location The alphanumeric se

23、ction is located to the right of and below a part of the function section and to the left of the editing and the numeric sections, see ISO/IEC 9995-l; its extent is from column 99 to col- umn 15. 6 Division into zones The alphanumeric section is divided into zones as il- lustrated in figure 1. 1 ISO

24、/IEC 9995-2:1994(E) o ISO/IEC Not drawn to scale - all lines are only indicative Figure 1 - Division of the alphanumeric section into zones ZAO is the alphanumeric zone of the alphanumeric section. The zones ZAl, ZA2, ZA3 and ZA4 are the function zones of the alphanumeric section. The ar- rangement,

25、 the number, and the locations of the keys as well as the allocation of graphic characters and of several functions to the keys are specified in clauses 7 and 8 of this part of ISO/IEC 9995. 7 Arrangement and location of keys in the alphanumeric zone of the alphanumeric section The graphic keys and

26、the space bar shall be arranged in the alphanumeric zone ZAO. 7.1 General keyboard arrangement The graphic keys and the space bar shall be located as illustrated in figure 2. There shall be 45 or more graphic keys and the space bar in the alphanumeric zone of the alphanumeric section. They shall be

27、arranged as follows: - the space bar in row A, extending, as a minimum, from position A03 to A07; - 10 keys or more in row B in positions BOO to Bl 1; - 11 keys or more in row C in positions CO1 to Cl 5; - 12 keys or more in row D in positions DO1 to D15; - 12 keys or more in row E in positions EOO

28、to El 5. This arrangement accommodates existing IS0 and national layouts and is flexible enough to allow poss- ible extended versions, especially for national linguis- tic requirements. The precise boundary of zone ZAO will be dependent on the number of keys and their configuration. In order to impl

29、ement the complementary layouts as specified in ISO/IEC 9995-3, 48 graphic keys are re- quired. 7.2 Harmonized 48 graphic key keyboard arrangement On a harmonized keyboard having 48 graphic keys and a space bar, the keys and the space bar shall be lo- cated as illustrated in figure3. There shall be

30、48 graphic keys and the space bar in the alphanumeric zone of the alphanumeric section. The 48 keys shall be arranged as follows: - the space bar in row A, extending, as a minimum, from position A03 to A07; - 10 keys in row B in positions BOl to BlO, or 11 keys in positions BOO to BlO; - 12 keys in

31、row C in positions CO1 to Cl 2; - 12 keys in row D in positions DO1 to D12; - 13 keys in row E in positions EOO to El 2, or 14 keys in positions EOO to E13. 8 ISO/IEC ISO/IEC 9995-2:1994(E) t -i 1 I t I C C F I I r Not drawn to scale - all lines are only indicative.

FigureA. shows a typical arrangement of a subset of the Latin alphabet

45、as can be found on many national layouts. The figure is provided for information only. It may be of assistance in the development of new national standards. Only capital forms of the letters are shown in figureA. or tableA.l. It is understood that the small forms of these letters are allocated to le

46、vel 1 of the keys and the capital forms are allocated to level 2. NOTES on figure A.1 : 1) Digit one to digit nine are allocated to the keys in positions EOI to E09, the digit zero is normally allo- cated to the key in position El0 and sometimes to the key in position EOO. Depending on national cust

47、om the digits are allocated to level 1 or to level 2. In a keyboard which has the digits allocated to the keys in the numeric zone of the numeric section the digits may be omitted from the alphanumeric zone. 2) Depending on national custom the different graphic characters allocated to the keys are s

48、hown in table A. 1. 3) The graphic character Space is allocated to the space bar on level 1 and level 2. The graphic character No-Break Space, if present, is allocated to level 3 of the space bar. 4) The graphic character Soft Hyphen, if present, is preferably allocated to level 3 of the key to whic
