Abstract: An armrest (1) for providing wrist and forearm support during keyboard and mouse operations is provided. The armrest (1) is placed at the front edge of the keyboard and supports most of the forearm from the elbow to the wrist so that the operator can operate the keyboard and handle the mouse, with the forearm supported close to the keyboard. The armrest (1) includes an enlarged support area (12, 22), an elbow protrusion area (13) at the longitudinal ends of the armrest (1), and two mouse pads (2: 21, 22) on the same surface running from the center area (11, 21) to one of the longitudinal ends. The armrest is positioned so that the center area (11, 21) of the mouse pad (2) faces the space bar (4), and the enlarged support area (12, 22) faces the number keypad (5) and projects out to the right of the number keypad.

Abstract: A chair with an automatic seat which cyclically inclines is configured with a forward/backward cyclically inclining mechanism (8) which supports the seat (6) supplied separate from and independent of the backrest (2) so that the seat can be inclined forward and backward and driven mechanically to incline by continuously changing its inclining angle. The inclination direction of the seat can be automatically reversed within a specified angle range. In addition, the chair is equipped with a rightward/leftward cyclically inclining mechanism (13) which is rectangularly installed beneath the forward/backward cyclically mechanism (8) to support it along with seat 6 to allow and drive inclination in the rightward and leftward directions.
