Abstract
In a shutter device for use with a camera lens assembly, the shutter device includes a shutter base, a shutter blade is rotatably mounted on the shutter base, a magnet movably coupled to the shutter base so as to enable rotation of the shutter blade, and a yoke extending lengthwise while facing the magnet wherein the movement range of the shutter base is limited within a length of the yoke. The zoom-in/zoom-out operation is enabled by moving only the shutter base, thus enabling a compact size fabrication of the camera lens assembly. The shutter blade is easily installed adjacent to a diaphragm, and the operational speed of the shutter blade is controlled by adjusting the structure of an electronic coil.
Claims15
A camera lens assembly with a shutter device, the shutter device comprising:
- a movable shutter base adapted for slidable arrangement lengthwise along a camera lens assembly;
- a shutter blade rotatably mounted on the shutter base;
- a driving unit comprising a magnet movably coupled to the shutter base so as to enable rotation of the shutter blade;
- and
- a yoke extending lengthwise to the magnet, wherein said yoke further comprising a stop means for limiting a lengthwise movement of the movable shutter base to no more than a length of the yoke.
A camera lens assembly with a shutter device, the shutter device comprising:
- a shutter base;
- a shutter blade rotatably mounted on the shutter base;
- a magnet movably coupled to the shutter base so as to enable rotation of the shutter blade;
- and
- a yoke extending lengthwise while facing the magnet, wherein movement range of the shutter base is limited within a length of the yoke, and
- a guide rail extending lengthwise and at least one guide arm, wherein the guide rail extends by passing through the guide arm so that the guide arm slidably moves along the guide rail.
A camera lens assembly with shutter device, the shutter device comprising:
- a shutter base;
- a shutter blade rotatably mounted on the shutter base;
- a magnet movably coupled to the shutter base so as to enable rotation of the shutter blade;
- and
- a yoke extending lengthwise while facing the magnet, wherein movement range of the shutter base is limited within a length of the yoke, and
