The Japanese "Kana" typewrite is going to be widely used in offices. But the arrangement of letters and numbers on the keyboard is not standardized among various manufactures. A study was made to determine the ideal arragement in the keyboard for maximum efficiency in man-machine system. On the side of machine, sizes of various keyboards, loads for each row as conferred by hands, and fingers were measured. And on the side of man, the physiological capacities of fingers were analyzed. Working area of fingers or motion of upper extramities related to typwriting, anatomical position of the finger phalanges, electromyogramm, tapping rate and compound reaction time were observed on skilled and unskilled typists. It is suggested from the analysis of the data secured in these investigations that keys of the "Kana" typewriter are not so arranged that the load of each finger is fitted to the physiological capabilities of the finger.
