CASIO Computer Co. Ltd began trading under that name in June 1957; a year which coincided with the marketing of the world’s first compact all-electric calculator, the Casio 14-A.

The CASIO name is an anglicised version of the family name of the company’s founders, Tadao and Toshio Kashio.

Well-known for their calculators and their watches, CASIO also produced clocks, digital cameras, electronic musical instruments, label printers, page printers, and office computers.

Less well-known, in fact unworthy of a mention in either the company’s history or its chronology of main products, is the Casiowriter® range of thermal “baby wedges”. Produced in the mid-to-late ’80s,  models included the CW-10, -11, -16, -17, -18, -20, -25, and -30.

Dating information is hard to come by, but a CW-16 was listed on eBay as “1984” (unverified). The CW-16 was also advertised for sale (offer price £104.95) in a November 1987 edition of New Scientist …

Non-thermal, i.e. daisy wheel, CW-600/650 Casiowriter typewriters do exist, and many of these are listed for sale in Eastern Europe. This one found its way to Perth and into my collection …

It’s the first electronic wedge I’ve bought in pristine condition ($20), still in its original box.

More about this typewriter in a future post.

The true identity of these “CASIO” typewriters is perhaps revealed by the fact that Casio CW-600/650 model numbers crop up in Nakajima ribbon listings.
