The work of preparing Interna

15、tional Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with

16、ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an I

17、nternational Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO10197 was prepared by Technical Committee ISO/TC171, Micrographics and optical memories for document and image recording, storage and use.iv blankISO10197:1993(E) BSI 02-2000 1 1 Sco

18、pe This International Standard specifies the essential performance characteristics of reader-printers designed for viewing and making hard copies from microfilm with a maximum width of35mm, whether in microfilm strips or in roll form, in open reels, cartridges or cassettes, microfiche, jackets and i

19、mage cards. It applies to reader-printers with a magnification less than or equal to50:1. The requirements for the functions of readers, as specified in ISO6198, are summarized in clause4 for convenience of the users of this International Standard. This International Standard establishes minimum cri

20、teria for the hard copy prints produced by reader-printers based on the use of microtest charts ISO No.1 and ISO No.2 or from microforms with a specified minimum quality, either an original or a duplicate. This International Standard does not apply to special reader-printers that produce colour or o

21、ther types of specialized microforms or prints. In addition, it does not necessarily apply to enlarger-printers. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

29、tions given in ISO6196 and the following definitions apply. 3.1 reader-printer device which serves both as a reader and a printer and implies the provision of a viewing screen large enough to display a full-size, or nearly full-size, image of the original document. Reader-printers are usually design

30、ed for image and print sizes up to A3 or A2 3.2 enlarger-printer device intended primarily for printing possibly having a limited viewing facility for image alignment and verification but not for detailed reading. These devices, sometimes also known as production printers, are usually designed for s

31、izes in the range A2 to A0 1) To be published.ISO10197:1993(E) 2 BSI 02-2000 4 Performance characteristics of the reader portion The essential performance characteristics are specified in ISO6198. For the convenience of the user, the requirements of the reader portion which pertain to reader-printer

32、s are summarized below. For methods of verifying the compliance with these requirements, see ISO7565. 4.1 Magnification The magnification shall be within5% of the nominal value indicated by the manufacturer. If multiple lenses are available for different magnifications, they shall be appropriately m

33、arked. 4.2 Image quality 4.2.1 Image resolution With the appropriate microtest chart in the film gate, the character or pattern resolved on the screen shall be, at a minimum, that specified in column2 of Table 1 or Table 2. The test image used shall be capable of resolving at least four patterns hig

34、her than specified in Table 2 for the appropriate magnification. 4.2.2 Image distortion Image distortion shall be less than0,5% due to curvilinear effects and2% for geometric effects. 4.3 Screen luminance and contrast 4.3.1 Screen luminance At all points in the useful (measurement) area of the scree

35、n, the luminance shall not be less than35cd/m 2 . The minimum luminance at the centre of the screen shall be140cd/m 2 . For rear projection readers, the luminance between the maximum value and the minimum value shall not exceed a ratio of10 except for those reader portions of reader-printers with ve

36、ry large screens. Screens having a diagonal greater than540mm are considered very large and the luminance ratio shall not exceed15. For front projection readers, the luminance between the maximum value and the minimum value shall not exceed a ratio of5. 4.3.2 Screen contrast The screen contrast expr

37、essed as a luminance ratio shall be a minimum of10. The light leakage from the reader portion of the reader-printer shall be restricted so that neither direct nor reflected rays will reduce the image quality.

38、he screen image and in the hardcopy Table 2 Minimum sized ISO microtest chart No.2 pattern to be resolved in the screen image and in the hard copy 4.4 Film accommodation The reader portion of the reader-printer shall accommodate the specific microform type(s) and size(s) for which the reader portion

39、 of the reader-printer was designed and display the images in an upright and right-reading manner.

The reader por

43、tion of roll film readers shall be designed so as to minimize abrasion of the film image area during transport of the film through the reader portion of the reader-printer. The film carrier or other film positioning mechanism shall be designed to accommodate a reel, cartridge or cassette as specifie

44、d in ISO1116, ISO7761-1 or ISO7762 and so that it will not abrade the film. 4.5 Focus A suitable and easily accessible means shall be provided for adjusting the focus of the image for any of the microforms for which the reader portion of the reader-printer was designed. The image shall remain in foc

45、us when a large frame is scanned or when the reader-printer is moving images from one frame to another on the same microform, unless roll microfilm is being transported at high speed, in which case when any image is viewed, it shall appear in best focus. 4.6 Controls All operator controls shall be r

46、eadily accessible and easy to use from the normal operating position. The controls shall be marked in the language which is acceptable to the country in which the devices will be sold or marked with ISO/IEC standard symbols (see IEC417H). 5 Performance characteristics of the printer portion 5.1 Pape

47、r requirement 5.1.1 Paper sizes The printer portion of the reader-printer shall accommodate one or more of the paper sizes specified in ISO216. By agreement between manufacturers and users, other paper sizes are acceptable. If the paper is supplied in roll form, the cut length from the roll shall ha

48、ve a3mm tolerance from the length or width specified. 5.1.2 Paper handling The paper feeding system shall be easy to load and thread. A sketch showing the threading path and any instructions for clearing a paper jam shall be in a conspicuous place. If a temperature of above40 C is required to proces

49、s the hard copy, the heating chamber shall be labelled with a warning (e.g.“CAUTION-HOT”) or with the appropriate ISO/IEC symbol. The paper driving mechanism shall not cause misalignment of the paper by more than5mm/m when the paper is properly threaded. NOTE 1Misalignment applies to either sideways or twisting displacement. The hard copy prints should be available for use within30s from the time the print cycle is activated. 5.1.3 Paper characteristics The paper surface after processing shall be capable of being marke
