    Abstract: 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.

  • Patent number: 9099261
    Abstract: 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.
