A Rare Toshiba Typewriter from the 1950s Operates with a Trilingual Index of Thousands of CharactersApril 29, 2021
In the 1940s, Toshiba began producing index typewriters with massive, horizontal cylinders containing thousands of symbols. One edition, the BW-2112—watch the demonstration by the New Orleans-based Typewriter Collector above to see how the redesign utilizes manual rotation and a metal pointer to print the characters—was a particularly advanced model with keys in three languages: Japanese, Chinese, and English.
The trilingual device ordered the characters in a manner similar to what you’d find in a Japanese dictionary, which is explained on the Typewriter Collector’s page as follows:
They’re arranged phonetically by most common “on-yomi” (or kun-yomi in some cases) according to the kana syllabary (many homophones, of course)… Red characters help parse the readings.
