Patent ID: 7471888

Claim:
An image pickup device comprising: a main body; a lid structure, slidable on a first surface of said main body between closed and open positions, positioned to lie on said first surface when in said closed position, and positioned to uncover at least part of said first surface when in said open position; an image sensor, incorporated in said main body, for picking up an image; a first optical system, having a first optical axis extending erectly from said first surface, for receiving object light incident thereon; a second optical system, having a second optical axis extending substantially in parallel with said first surface, for introducing said object light to said image sensor; a path bending optical element for introducing said object light to said second optical system by changing an optical path of said object light from said first optical system; and an optical system container, extendable according to sliding of said lid structure, for containing said first and second optical systems and said path bending optical element, for entering said main body when said lid structure is in said closed position, to decrease an optical path length of said second optical system, and for protruding from said main body when said lid structure is in said open position, to increase said optical path length of said second optical system.
