Abstract: A band saw machine includes a working platform, a cutting machine, a vertical displacement element causing the cutting machine to move vertically, a height sensor and a central processor. The working platform includes a reference plane for placing a workpiece. The cutting machine includes a driving wheel, a driven wheel, a band saw wound on the driving wheel and the driven wheel, and a motor that electrically drives the driving wheel. The band saw includes a starting cutting tooth and a processing cutting tooth sequentially arranged. The height sensor detects a starting cutting point of the workpiece farthest from the reference plane. The central processor receives information of a position of the starting cutting point, and controls a displacement speed of the vertical displacement element and a first rotational speed of the motor to cause the starting cutting tooth to first cut at the starting cutting point.

Abstract: Electronic apparatus includes a display component, a base, a moveable case, and a transmission component. The display component includes a rotational shaft. The base is pivotally connected to the rotational shaft. The base has an opening. The moveable case is pivotally connected to the base. The moveable case can selectively cover or uncover the opening. The transmission component is disposed on the base. The transmission component is operatively connected between the rotational shaft and the moveable case. When the display component is rotated away from the base, the rotational shaft actuates the moveable case to rotate to uncover the opening through the transmission component. When the display component is rotated toward the base, the rotational shaft actuates the moveable case to rotate to cover the opening through the transmission component.
