ABSTRACT:
A multiple focal length folding imaging device includes a first and second housing which are operably joined together for movement relative to one another so that the second housing is movable relative to the first housing between at least a first position and a second position. The first housing is formed to at least partially receive therein the second housing, such that when the second housing is in the first position, the second housing is at least partially received within the first housing. The second housing includes an exiting aperture for allowing exiting of at least one image recordable unit therefrom when in the second position, and when the second housing is in the first position, the exiting aperture is at least partially disposed within the first housing so that the at least one image recordable unit cannot exit from the exiting aperture. Furthermore, the imaging device includes a lens movement mechanism for transferring linear motion to rotational motion so that different lens systems can be readily moved into the optical path of the imaging device.
