Image detecting module
The invention provides an image detecting module including a base, a carrier movably disposed on the base, an image detecting unit disposed on the carrier, a contact portion fixed to the carrier, and a fixed member fixed to the base. The fixed member has a protrusion movably contacting a recess of the contact portion. When an external force is exerted on the base and the carrier moves with respect to the base, the protrusion slides on a surface of the recess. When the external force is released, the protrusion slides to the bottom of the recess, such that the carrier is held in a predetermined position with respect to the base.
1. An image detecting module, comprising:
a base,
a carrier movably disposed on the base and substantially parallel to a plane;
a contact portion fixed to a side of the carrier, comprising a recess;
an image detecting unit disposed on the carrier; and
a fixed member fixed to the base, comprising a protrusion movably contacting the recess, wherein when an external force is exerted on the base and the carrier moves with respect to the base in a first direction, the protrusion slides on a surface of the recess, and when the external force is released, the protrusion slides to the bottom of the recess, such that the carrier is held in a predetermined position with respect to the base.
2. The image detecting module as claimed in claim 1 , wherein the first direction is substantially parallel to the plane.
3. The image detecting module as claimed in claim 1 , wherein the surface of the recess is curved with the protrusion sliding thereon when the carrier moves with respect to the base.
4. The image detecting module as claimed in claim 3 , wherein the contact portion further comprises a hole at the bottom of the recess.
5. The image detecting module as claimed in claim 1 , wherein the recess comprises a plurality of slopes defining a pyramidal space, and the protrusion slides on the slopes when the carrier moves with respect to the base.
6. The image detecting module as claimed in claim 1 , wherein the recess comprises four symmetrical slopes defining a pyramidal space, and the protrusion slides on the slopes when the carrier moves with respect to the base.
7. The image detecting module as claimed in claim 1 , wherein the protrusion comprises a curved sliding surface sliding on the surface of the recess when the carrier moves with respect to the base.
8. The image detecting module as claimed in claim 1 , wherein the fixed member is longitudinal with the protrusion formed at an end thereof.
9. The image detecting module as claimed in claim 1 , wherein the recess is integrally formed with the contact portion in one piece.
10. The image detecting module as claimed in claim 1 , wherein the protrusion is integrally formed with the fixed member in one piece.
11. An image detecting module, comprising:
a base,
a carrier movably disposed on the base and substantially parallel to a plane;
a contact portion fixed to a side of the carrier, comprising a protrusion;
an image detecting unit disposed on the carrier; and
a fixed member fixed to the base, comprising a recess movably contacting the protrusion, wherein when an external force is exerted on the base and the carrier moves with respect to the base in a first direction, the protrusion slides on a surface of the recess, and when the external force is released, the protrusion slides to the bottom of the recess, such that the carrier is held in a predetermined position with respect to the base.
12. The image detecting module as claimed in claim 11 , wherein the first direction is substantially parallel to the plane.
13. The image detecting module as claimed in claim 11 , wherein the surface is curved with the protrusion sliding thereon when the carrier moves with respect to the base.
14. The image detecting module as claimed in claim 13 , wherein the contact portion further comprises a hole at the bottom of the recess.
15. The image detecting module as claimed in claim 11 , wherein the recess comprises a plurality of slopes defining a pyramidal space, and the protrusion slides on the slopes when the carrier moves with respect to the base.
16. The image detecting module as claimed in claim 11 , wherein the recess comprises four symmetrical slopes defining a pyramidal space, and the protrusion slides on the slopes when the carrier moves with respect to the base.
17. The image detecting module as claimed in claim 11 , wherein the protrusion comprises a curved sliding surface sliding on the surface of the recess when the carrier moves with respect to the base.
18. The image detecting module as claimed in claim 11 , wherein the fixed member is longitudinal with the protrusion formed at an end thereof.
19. The image detecting module as claimed in claim 11 , wherein the protrusion is integrally formed with the contact portion in one piece.
20. The image detecting module as claimed in claim 11 , wherein the recess is integrally formed with the fixed member in one piece.
