With the relay calculator enjoying strong sales to large corporations and research institutions, Casio continued to grow. In order to meet the growing demand, a new factory was built in Yamato-machi, entering full production in 1960. Energy was also put into the development of new products, and new types of calculators were released one after another, including the TUC Compuwriter, an automatic form output device that connected to an electric typewriter, and the AL-1 calculator for scientific and technological use. Casio continued to lead the market.
