The Nippo Machine Company was founded by Jin Inoue in Yokohama in 1945 and in 1956 started making calculating machines and, using a similar model numbering pattern, a small portable typewriter called the Atlas. Nippo had gained the rights from Royal-McBee Nederlands NV to use the mechanical design which had started out in 1952 as the Halberg and in 1954 became the Royalite. In 1957 Royal introduced new-look portables designed for it by Laird Fortune Covey.
Nippo continued to use the Halberg mechanical design throughout its typewriter-making years. The Atlas was also marketed as the Cherryland, Del Mar, Elgin, Collegiate and Wellon. Later Nippo portables included the P-100 (also the Morse P-100), P-200 (also known as the Argyle P-201) and P-300, as well as the Baby Alpina, Condor, Rexina, Jaguar and Clipper and no doubt a few others.
Nippo stopped making calculators in 1961 to concentrate on typewriters and became a public corporation in 1963. But it found it difficult to compete against the superior quality and reliability of Brother portables, which were introduced in 1962. Brother also quickly established a far wider distribution network. Nippo’s founder died in 1973 and his son, Yuichi Inoue, took over the company and attempted a merger with a thermistor manufacturer in 1989. That company collapsed. Yuichi Inoue now runs Nippomac.
