11、andardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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 rig

12、ht to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International

13、 Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as a

14、n International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO

15、7761 was prepared by Technical Committee ISO/TC 171, Document management applications, Subcommittee SC 2, Application issues. ISO 7761:2004(E) ISO 2004 All rights reserved vIntroduction With the acceptance of this International Standard, future readers and reader-printers will be designed to accept

16、cartridges used for storing and viewing processed 16 mm microfilm over a full range of specified tolerances. Figure 4 provides the dimensions for a reel that provides additional clearance between the flanges of the reel and the inner walls of the enclosed cartridge described in Figure 2. Reels made

17、to the specification in Figure 4 are suitable for all applications. Reels made to the upper limit of dimension B (see Figure 3) may rub the inside wall of the enclosed cartridge. Figure 2 includes dimensions 2S and 2T. The addition of the 2S dimension reduces the clearance of the flanges of the reel

18、 with the sides of the enclosed cartridge. The 2S and 2T dimensions are only necessary when an M-style cartridge reel (metal insert drive) is housed in the ISO 7761 standard enclosed case. These dimensions are necessary to control the wide leader in the M-style cartridge. This International Standard

19、 also specifies the winding of the processed microfilm on the reel and the physical characteristics of the leading end of the film to ensure proper interfacing of the cartridges with automatic threading readers and reader-printers of different makes.
