Foreword
ISO (the International Organization for Standardization) 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 right 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 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 an
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 7761 was prepared by Technical Committee ISO/TC 171, Document management applications,

Introduction
With the acceptance of this International Standard, future readers and reader-printers will be designed to
accept 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 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 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 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.

4 Requirements for cartridge assembly
4.1 Dimensions
The following requirements pertain to the cartridge assembly, which is composed of the outer enclosure
section (see Figures 1 and 2) and a reel (see Figures 3 and 4) assembled thereto and which is to be referred
to as “the cartridge”.
The cartridges shall be in conformity with the dimensions given in either Figure 1 or Figure 2.
4.1.1 Open cartridge
The following requirements pertain to the cartridge in Figure 1, assembled with a reel (see Figures 3 and 4).
The cartridge clip (outer piece) shall conform to the dimensions given in Figure 1 and Table 1.
4.1.1.1 Dimensional tolerances
For fillet radii: 0,40 mm minimum, 1,60 mm maximum.
For outside corner radii: 0,40 mm minimum, 0,80 mm maximum.
4.1.1.2 Moulding tolerances
For general dimensions up to 25,4 mm ± 0,10 mm.
For each additional 25,4 mm ± 0,03 mm.
For parting-line dimensions up to 25,4 mm ± 0,10 mm.
For each additional 25,4 mm ± 0,03 mm.
