20090110385Micro camera module with discrete manual focal positions - 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.04-30-2009

20130129335AUTO-FOCUS MECHANISM FOR VISION SYSTEM CAMERA - This invention provides an electro-mechanical auto-focus function for a smaller-diameter lens type that nests, and is removably mounted, within the mounting space and thread arrangement of a larger-diameter lens base of a vision camera assembly housing. In an illustrative embodiment, the camera assembly includes a threaded base having a first diameter, which illustratively defines a C-mount base. A motor-driven gear-reduction drive assembly is mounted internally, and includes teeth that engage corresponding teeth on the outer diameter of a cylindrical focus gear, which has an internal lead screw. The focus gear is freely rotatable, and removably captured, within the threaded C-mount base in a nested, coaxial relationship. The internal lead screw of the focus gear threadingly engages the external threads of a coaxial lens holder. This converts the drive gear rotation into linear/axial lens holder motion. The lens holder includes anti-rotation stops, which allow its linear/axial movement but restrain any rotational motion.05-23-2013
