Abstract
A lens retracting structure includes a housing, an image-forming lens set moveably supported on two parallel guide rods inside the housing, and a driving mechanism for moving the image-forming lens set along the parallel guide rods between a first position and a second position by means of the engagement of a threaded coupling member of the image-forming lens set with a threaded shaft which is rotatably driven by a motor of the driving mechanism.
Claims9
A lens retracting structure comprising:
- a housing having a guide member therein;
- an image-forming lens set having a barrel-shaped lens body;
- two longitudinal grooves disposed on opposite side of a periphery of the barrel-shaped lens body, wherein at least one of the grooves is configured to accommodate the guide member;
- the image-forming lens set is supported on said guide member inside said housing and movable along said guide member between a first position and a second position reciprocally, said barrel-shaped lens body of said image-forming lens set is connected to a threaded coupling member;
- and
- a driving mechanism mounted inside said housing, said driving mechanism having a motor and a transmission device having a shaft rotatable by the motor, said shaft having a threaded actuating portion engaged with the threaded coupling member for driving said image-forming lens set to move along said guide member between said first position and said second position upon rotation of said shaft driven by said motor, the thread coupling member and the lens body are in communication as a unit such that said shaft is configured to directly drive the image-forming lens set to move toward the first position and to move toward the second position reciprocally.
