摘要： A keyswitch includes a casing, a key cap and a support device rotatably disposed between the key cap and the casing. One of the casing and the key cap has a first magnetic area and the support device has a second magnetic area corresponding to the first magnetic area. When the key cap is not pressed, a magnetic attraction force between the first and second magnetic areas keeps the key cap at a non-pressed position. When the key cap is pressed by an external force such that the second magnetic area moves away from the first magnetic area, the key cap moves from the non-pressed position toward the pressed position. When the external force is removed, the second magnetic area moves toward the first magnetic area due to the magnetic attraction force such that the key cap moves from the pressed position toward the non-pressed position.

摘要翻译： 键开关包括壳体，键帽和可旋转地设置在键帽和壳体之间的支撑装置。 壳体和键帽中的一个具有第一磁性区域，并且支撑装置具有对应于第一磁性区域的第二磁性区域。 当未按下键帽时，第一和第二磁性区域之间的磁吸引力将键帽保持在非按压位置。 当钥匙盖被外力按压使得第二磁性区域离开第一磁性区域移动时，钥匙盖从非按压位置朝向按压位置移动。 当除去外力时，由于磁吸引力使第二磁性区域朝向第一磁性区域移动，使得键帽从按压位置朝向非按压位置移动。

摘要： A dust cleaning apparatus comprising a sieve, a beater and a driver is provided. The beater includes a moving part and a beating part. The moving part rotates around a shaft for a circular motion or vibrates relative to a supporting rod for a vibration motion. The beating part is disposed on the moving part and beats the sieve by the movement of the moving part. The driver connects the shaft or the supporting rod to drive the moving part in motion.

摘要： A projection device with a color wheel locking function is provided. The projection device includes a light source, a first color wheel unit, a first spindle motor, a magnetic locking mechanism and a control unit. The light source generates a light beam. The first color wheel unit has at least one transparent region through which the light beam transmits. The first spindle motor is to be enabled to rotate the first color wheel unit, and disabled to stop rotating in correspondence with an external magnetic force. The magnetic locking mechanism abuts upon the first spindle motor and generates the external magnetic force. The control unit controls the magnetic locking mechanism. When the first spindle motor stops in correspondence with the external magnetic force, a position of the at least one transparent region corresponds to the light source so that the light beam transmits through the transparent region.
