In Monday's editions of Washington Business, a story on office automation incorrectly identified one of the leading manufacturers of office machines. The firm is Digital Equipment Corp.

Office automation got off to an auspicious start several years ago with the electric typewriter and the copier, but these now familar machines are beginning to look like relics next to the latest office equipment.

Some examples:

Word Processor/Display Writer. Now a must for every executive work station, these machines use the traditional typewriter keyboard to compose, edit, correct, print, copy and store material. More advanced versions of this equipment, on view at The Paperless Office in the Watergate Mall, can scan type, make corrections and put the text into the computer in electronic form -- which saves typing. A color graphics system can put budget charts and population graphs together in eight colors.

Briefcase Reader. A useful product for the executive on the go, this is an attache case that comes with a microfilm projector and mini-screen, enabling the business traveler to take along hundreds of documents on microfilm.

Storage. File cabinets are becomingobsolete. Space is at a premium, and it is cheaper in the long run to store office records and other information in the computer or on microfilm and microfiche.

Computerized Message Center. This newest idea for answering the office telephone has been set up at the Planning Research Corp. in McLean. A computer tells telephone attendants who it is being called and lets them answer the phone as though they were personal secretaries. The "boss" finds the message in his terminal, where it is easy to read and won't get lost under a stack of papers.

Other firms have installed electronic calendar systems, letting office workers set up meetings with each other at a glance of schedules blocked out in the computer. And what's known as an "electronic tickler system" lets managers monitor work progress while reminding employes of project deadlines.

Ahead? Industry analysts report that Japan is experimenting with audio input systems that translate the human voice into printed copy.
