ISO/IEC Copyright Office l Case Postale 56 l CH-1211 Geneve 20 l Switzerland Printed in Switzerland ii Q ISO/IEC Foreword IS0 (the International Organization for Standardization) and IEC (the Inter- national Electrotechnical Commission) form the specialized system for worldwide sta
11、ndardization. National 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 field
12、s of mutual interest. Other international organizations, 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
13、by the joint technical 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.

17、 0 ISO/IEC ISO/IEC 9995-4:1994(E) Information technology - Keyboard layouts for text and office systems - Part 4: Numeric section 1 Scope Within the general scope described in part 1 of ISO/IEC 9995 this part of ISO/IEC 9995 specifies the numeric section of a keyboard and the division of that sectio
18、n into zones. It specifies the arrangement, the number, and the location of the keys in the numeric zone ZNO and in the function zones ZNI to ZN6 of the numeric section, as well as the allocation of functions to the keys. The numeric zone ZNO is to be used in keyboards for applications such as text
19、and data processing; general office environment; banking; point of sales (POS); telematic services; telephony apparatus; home elec- tronic systems; numerical control of machinery and equipment; input of personal identification number (PIN); etc. The function zones ZNI to ZN6 are to be used in keyboa
20、rds for applications such as data entry, text and data processing, general office environment, etc. NOTE 1 Certain of these applications are under the re- sponsibility of the ITU-T. 2 Conformance Equipment is in conformance with this part of ISO/IEC 9995 if it meets the requirements of clauses 5 to
21、10 and either 8.1 or 8.2. 3 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 9995. At the time of publi- cation, the editions indicated were valid. All standards are subject to revision, and parties t
22、o 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 IEC and IS0 maintain registers of currently valid International Standards. ISO/IEC 9995-l : 1994, information technology - K

26、section. The arrangement, the number, and the locations of the keys as well as the allocation of functions to the keys are specified in clauses 7 and 8. ZNI to ZN6 are the function zones of the numeric section. The arrangement, the number, and the lo- cation of the keys as well as the allocation of
27、func- tions to the keys are specified in clause 9. 7 Arrangement, location and functions of the keys in the numeric zone The keys shall be arranged in the numeric zone ZNO and be located as illustrated in figure2. The functions to be allocated to the keys of the nu- meric zone are the digits zero to
28、 nine, the decimal separator, and two telematic functions.

The decimal separator and the telematic functions shall be allocated as defined in 8.1 or 8.2. 8.1 The “l-2-3” layout This layo
30、ut is primarily intended for general office applications, text and data processing, and other applications such as telematic services, telephony apparatus, home electronic systems, numerical con- trol of machinery and equipment. It is also rec- ommended for combined voice/data terminal equipment. Th

Recommended functions are: - space character, for possible use as triad separ- ator; - single zero, increasing the area from which the digit zero can be entered; - double zero. No function is allocated
35、to the key in position A50. Recommended functions are: - single zero, increasing the area from which the digit zero can be entered; - double zero; - triple zero, in addition to a single zero or in con- nection with the double zero on the key in position A51. If required to cater for trained personne
36、l, or to have uniformity of layouts within an installation, the “7-8-9” layout (see 8.2) may also be provided for the applications listed above. 8.2 The “7-8-9” layout This layout is primarily intended for applications such as data entry, and other general office applications. The allocation of the
37、functions of the “7-8-9” layout shall be as indicated in table2; see also figure4.

This allocation shall apply o
46、nly if the four arithmetic operators (or the equivalent graphic characters) are allocated to the keys in row E. The key in position A-B54 will have the function ad- dition or the function enter as required by the appli- cation. If a tabulation function or an alternative decimal separator is required
47、, the relevant function shall be allocated to the key in position C54.
