Abstract
A novel micro camera module that is manually adjustable between a close-up mode and an infinite mode includes a lens assembly adjustably mounted within a sleeve that is adjustably mounted into a housing. In a particular embodiment the sleeve includes a channel (cam groove) that is engaged by a plurality of pins fixed to the housing. Further, a biasing member is disposed between the sleeve and the housing such that an upward force will enable the pins to firmly engage the lower portion of the channel. In a more particular embodiment, the channel defines two detents that secure the sleeve into predetermined positions with respect to the housing. In an even more particular embodiment, the channel is sloped such that upon rotation of the sleeve, the distance between the lens assembly and an image capture device is changed. In another particular embodiment, the camera module includes an electrical mode detecting switch that is indicative of the position of the camera module.
