This was the first Japanese language word processing product from Sharp. Its standard price was ¥2.95 million. It used the industry's first tablet input system, and was equipped with an ink jet printer. At the time, there were almost no people involved in clerical work who could handle a keyboard, and the touch-pen system was used to side-step the problem of "keyboard phobia".
Sharp took this opportunity to give the name "Shoin" their Japanese language word processors, and they subsequently released many models.
