摘要:
The language wheel has an interchangeable "wheel" with the same words of two languages in corresponding positions on the wheel. Two cursors are coupled together so the when one is manually moved to indicate a particular word, the other indicates the corresponding word. The two cursors are mounted on a pivoted bar which rotates above the language wheel and the cursors move radially in and out on the bar.
