Abstract:
1. A pop-up camera module comprising: a camera part that embeds a camera comprising an image pick-up device and a lens; a side cover which is situated at an opposite side of a camera case part from the camera part; a length changing unit which connects the side cover and the camera part, and which is changeable in length along its longitudinal axis, the length changing unit comprising a fixing rod having one side connected to the side cover, and a displacing rod having one side connected to the camera part and another side connected to the fixing rod; a base cover which is situated between the camera part and the side cover, the base cover comprising one end into which the camera part protrudes and is stored, and another end which is connected to the side cover, the length changing unit passing through the base cover along a connecting axis of the camera part, and a rectilinear guide space being defined between the base cover and the length changing unit; and a flexible printed circuit board (FPCB) comprising an axial displacement part that electrically connects the image pick-up device and an external circuit board, the axial displacement part winding around the length changing unit in a helical shape within the rectilinear guide space, such that strain does not occur at the camera part or at the external circuit board when the length of the length changing unit is maximized, wherein the camera part comprises a camera storage part that stores a camera, a first guide cylinder part having a hollow cylindrical shape that extends from the camera storage part around a protruding axis toward the side cover, and a second guide cylinder part having a radius that is smaller than the radius of the first guide cylinder part and bigger than the radius of the length changing unit, and the FPCB comprises a rotation displacement part which is situated in a rotation guide space located between the first guide cylinder part and the second guide cylinder part, and which is disposed in plural layers along a circumferential direction to the second guide cylinder part, such that strain does not occur at the camera part or at the external circuit board when the length of the length changing unit is changed.
