Abstract

A camera device is packaged inside an external shell of an electronic apparatus. The external shell has an opening. The camera device has a transparent plate, a part of which is adjacent to the opening of the external shell. The transparent plate forms an accommodating space for accommodating other components of the camera device. Thus, the dust can be prevented from falling into a shutter blade room of the camera device. The camera device also includes a shutter blade, a driver, and a plate. The plate has an aperture, and the aperture of the camera device is defined thereby. The aperture of the plate is completely pervious to light when the shutter blade is at a first position, and the aperture of the plate is partially pervious to light when the shutter blade is at a second position, thereby changing the aperture of the camera device.

First claim

What is claimed is:

1 . A camera device, which is disposed in an electronic apparatus, comprising:
an optical system frame; the electronic apparatus having an external shell with an opening exposed; a lens system deployed in the external shell of the electronic apparatus and mounted on the optical system frame; a bottom plate fastened to the optical system frame or formed by extending from the optical system frame; a cover plate fastened to the bottom plate and distanced away from the bottom plate; at least one shutter blade disposed between the cover plate and the bottom plate, configured to adjust an aperture of the camera device; and a transparent plate forming an accommodating space for accommodating the optical system frame, the bottom plate, and the cover plate, the transparent plate being located in the external shell and a part of the transparent plate being located between the bottom plate and the opening of the external shell, or between the cover plate and the opening of the external shell.

2 . The camera device according to claim 1 , wherein the part of the transparent plate, the cover plate, the at least one shutter blade, and the bottom plate are arranged in order from the opening of the external shell to the lens system.

3 . The camera device according to claim 2 , wherein the cover plate has a first opening, the bottom plate has a second opening, and light rays are transmitted to the lens system sequentially via the opening of the external shell, the part of the transparent plate, the first opening, and the second opening or emitted out from the opening of the external shell in a reverse order.

4 . The camera device according to claim 1 , wherein the part of the transparent plate, the bottom plate, the at least one shutter blade, and the cover plate are arranged in order from the opening of the external shell to the lens system.

5 . The camera device according to claim 4 , wherein the cover plate has a first opening, the bottom plate has a second opening, and light rays are transmitted to the lens system sequentially via the opening of the external shell, the part of the transparent plate, the second opening, and the first opening or emitted out from the opening of the external shell in a reverse order.

6 . The camera device according to claim 1 , further comprising a fastening member having a base and an elongated part extending from the base, the bottom plate has a concave part, the base of the fastening member is accommodated in the concave part of the bottom plate, and the elongated part of the fastening member penetrates the concave part of the bottom plate and is fastened to the cover plate.

7 . The camera device according to claim 1 , wherein the optical system frame is made of a plastic material and the cover plate comprises a flat metal plate.

8 . The camera device according to claim 1 , wherein the lens system comprises at least two lenses and an aperture stop.

9 . The camera device according to claim 8 , wherein the aperture established by the at least one shutter blade is smaller than or equal to the aperture of the aperture stop of the lens system.

10 . A camera device, which is disposed in an electronic apparatus, comprising:
an optical system frame; the electronic apparatus having an external shell with an opening exposed; a lens system deployed in the external shell of the electronic apparatus and mounted on the optical system frame; a bottom plate having a first opening, the bottom plate being fastened to the optical system frame or formed by extending from the optical system frame, the bottom plate further having a concave part formed thereon; a cover plate having a second opening, the cover plate being distanced away from the bottom plate; a fastening member having a base and an elongated part extending from the base, the base of the fastening member being accommodated in the concave part of the bottom plate, and the elongated part of the fastening member penetrating the concave part of the bottom plate and being fastened to the cover plate; and at least one shutter blade disposed between the cover plate and the bottom plate, configured to adjust an aperture of the camera device, wherein light rays are transmitted to the lens system sequentially via the opening of the external shell, the first opening of the bottom plate, and an aperture established by the shutter blade, and the second opening of the cover plate, or emitted out from the opening of the external shell in a reverse order.

11 . A camera device with adjustable aperture, comprising:
an optical system frame; a lens system mounted on the optical system frame; a plate configured to be fastened to the optical system frame or be formed by extending the optical system frame, the plate having an aperture; a shutter blade coupled to the plate, the aperture of the plate being completely pervious to light when the shutter blade is at a first position, the aperture of the plate being partially pervious to light when the shutter blade is at a second position; and a driver connecting to the shutter blade for causing a displacement of the shutter blade.

12 . The camera device according to claim 11 , wherein the shutter blade has a hole disposed thereon, a diameter of the hole of the shutter blade is less than that of the aperture of the plate.

13 . The camera device according to claim 12 , wherein the driver makes the hole of the shutter blade move to a position overlapping the aperture of the plate.

14 . The camera device according to claim 12 , further comprising an additional shutter blade coupled to the plate.

15 . The camera device according to claim 14 , wherein the shutter blade and the additional shutter blade are disposed crossover from each other.

16 . The camera device according to claim 15 , further comprising an additional driver connecting to the additional shutter blade, the additional driver causing a displacement of the additional shutter blade.

17 . The camera device according to claim 16 , wherein the additional shutter blade has an additional hole disposed thereon, and wherein the additional driver makes the additional hole of the additional shutter blade move to a position overlapping the aperture of the plate.

18 . The camera device according to claim 14 , further comprising a cover plate configured to be distanced away from the plate, the shutter blade and the additional shutter blade being disposed between the cover plate and the plate.

19 . The camera device according to claim 14 , wherein the shutter blade and the additional shutter blade are pivotably connected to the plate.

20 . The camera device according to claim 17 , wherein the driver is configured to drive the shutter blade to a turn-on position or a turn-off position and the additional driver is configured to drive the additional shutter blade to the turn-on position or the turn-off position ;wherein when the driver drives the shutter blade to the turn-off position and the additional driver drives the additional shutter blade to the turn-on position, the aperture of the camera device is defined by the size of the hole of the shutter blade; when the driver drives the shutter blade to the turn-on position and the additional driver drives the additional shutter blade to the turn-off position, the aperture of the camera device is defined by the size of the additional hole of the additional shutter blade.
