Microform Readers Notes

Microfilmed records are viewed through a machine called a microfilm or microform reader or
a combination microfilm reader-printer. Reader-printers not only enlarge the microimage and
project it onto a viewing screen, but also project the image on sensitized paper and process it to
produce a paper printout.

Several types of microfilm readers are available today, including lap readers, portable readers,
desk readers, and free-standing units. Because each type is designed for one specific form of
microfilm, your selection will depend on the type of microform used by your company.
At a bank on the East Coast, the adjustment and payroll departments use computer output
microfiche and a reader-printer to answer inquiries about weekly payroll records or savings,
checking, and loan accounts. Telephone inquiries are handled quickly because of the fast access
to information, and the printer allows the operator to send a hard copy to the customer
immediately. Each 4x6 inch sheet in the files next to the telephone contains 207 microimages,
and the fiche is indexed by account number in a three-ring binder next to the reader-printer.
