Photographically sensitized microfilm for roll film ap- plicatio

6、ns is sold wound on spools or cores. The pur- pose of this standard is to compile, from already existing American National Standards Institute (ANSI) or Inter- national Standards Organization (ISO) standards, the available dimensions and corresponding tolerances of the most commonly used cores and s

7、pools in original record- ing equipment. It is hoped that, where possible, adher- ence to the standards listed will ensure maximum compatibility and interchangeability of sensitized products and exposing hardware. Some sizes of microfilm spools, notably 105mm, which are used in the industry, are not

8、 currently standardized. However, recommended dimensions for 105mm spools have been included to make the document more complete. Dimensions for “thin walled” paper-board cores Le., cores with wall thick- nesses of 7.6mm (0.30 inch) or less, which are routinely used in the microfilm industry for sens

9、itized duplicat- ing material, have not been included. The dimensions in ANSIIAIIM MS29-1992 are identi- cal to those in Draft International Standard (DIS) 1116, Microcopying - 16mm and 35mm Microfilms, Spools, and Reels. After publication, the new version of IS0 1ll6 will replace IS0 1116-1975. Thi

10、s standard is a revision of ANSI/AIIM MS29-1987, Micrographics - Cores and Spools for Recording Equip- ment - Dimensions. Suggestions for improvements of this standard are wel- come. They should be sent to the Chair, AIIM Standards I Board, Association for Information and Image Manage- ment, 1100 Wa

These drive holes ensure correct film orientation dur- ing loading in hardware utilizing two drive pins. See figure 1, Metal spool. The two offset drive holes

17、 are mandatory for plastic spools. Because of plastic molding techniques in use, the offset drive holes may be rotated from the position shown in figure 1, Metal spool. See figure 2, Plastic spool. However, in spite of their appearance, these drive holes shall be functionally the same. 45“ 4 Film sl

18、ot S in table 1 and figure 1 has been added to specify the minimum width of the film slot. The preferred spool design specified in this standard calls for a single keyway in both flanges (except 105mm). Planetary microfilm equipment presently exists which requires 35mm spools with a double keyway in

19、 one flange. Therefore, to permit manufacturing economies, 16mm and 35mm spools with double keyways in one or both flanges are recognized temporarily until the 35mm equipment in the field requiring a double keyway is phased out. However, some manufacturers will use only spools with single keyways; t

20、herefore, equipment manufacturers are advised against designing hardware that requires spools with double keyways.

27、ractice for the most commonly used spool which has a nominal ca- pacity of 30.5m (100.0 feet). See figure 3, Spool (105mm) and table 4, Dimensions for 105mm spools. NOTE: It should be pointed out that the “nominal” spool sizes referred to in table 2, table 3 and table 4, Dimen- sions for 105mm spool

28、s, are based on “full” spools when using films having nominal thickness of 0.139mm (0.0054 inch). It is recognized that due to the variety of microfilm thicknesses on the market, the actual length a full spool will hold is quite variable.

NOTE: No reference to length is used in core standards since only the manufacturers requirements for a partic- ular users equipment regulate the length of microfilm supplied on cores.
