Jan 31, 2005 - Samsung Electronics
A camera 26 is embedded in the camera part 20. The camera part 20 comprises a camera storage part 25, a first guide cylinder part 21, and a second guide cylinder part 22. The camera storage part 25 comprises a lower camera storage part 25a that usually stores the camera, and an upper camera storage part 25b that covers the camera, and further a storage fixing part 29 between the lower and upper camera storage parts 25a and 25b. The camera 26 comprises an image pick-up device 28, such as a CCD or a CMOS, and a lens 27 to photograph a picture. The camera part 20 is preferably situated at a distance from and in an opposing spatial arrangement with the side cover 30. In this regard, the side cover 30 and the camera part 20 are preferably connected by the length changing unit 40 that is changeable in length along a Z-axis direction.
The length changing unit 40 preferably inserts into and passes through the inside of the base cover 60. A rectilinear guide space Ss exists between the length changing unit 40 and the base cover 60. An axial displacement part 50a is mounted in the rectilinear guide space Ss to prevent the base cover 60 from being contacted from the outside due to a longer width of the axial displacement part 50a, thereby protecting the FPCB 50.
The FPCB 50 comprises the axial displacement part 50a. Referring to FIGS. 3, 4A, 4B, the axial displacement part 50a is formed to have a regular length and to change the length of the length changing unit 40 by a helicoidal motion. When the length changing unit 40 becomes longer, the axial displacement part 50a is formed to have a suitable length such that strain does not occur at either the camera part 20 or the exterior circuit board 70.
The FPCB 50 can further comprise a rotation displacement part 50b that is disposed in a plurality of layers and wound in the rotation guide space Sr. Preferably, in this regard, a sufficient distance exists between each layer of the rotation displacement part 50b and the second guide cylinder part 22, such that neither side of the FPCB 50 is not strained when the camera part 20 is rotated.
The rotation displacement part 50b and the axial displacement part 50a can be adjacent to each other, wherein, for example, the rotation displacement part 50bis formed along the Z axis and the axial displacement part 50a is tilted toward the Z axis. The rotation displacement part 50b and the axial displacement part 50apreferably do not influence each other, however. Preferably, in this regard, the FPCB 50 comprises a displacement connecting part 50c which is placed toward the Z axis and which connects the rotation displacement part 50b and the axial displacement part 50a to lessen or reduce strain on the FPCB 50, caused, for example, when the camera part 20 is rotated wherein the length of the axial displacement part 50a changes, and when the camera part 20 is protruded or stored wherein the length of the rotation displacement part 50b can change.
As shown in FIG. 5B, the rotation displacement part 50b is interposed between the first guide cylinder part 21 and the second guide cylinder 22. The second guide cylinder part 22 can comprise a plurality of protrusions 29 on the outer surface of the second guide cylinder part 22 which protrude along the Z axis, and which are situated at regular intervals. The rotation displacement part 50b can be formed on the protrusions 29 and placed in a recess between the protrusions 29, such that the rotation displacement part 50b has sufficient space to rotate and loosely wind the outer surface of the second guide cylinder part 22.
A plurality of protrusion guide parts 24 for guiding the rotation displacement part 50b in the rotation guide space Sr can be formed on the inner surface of the first guide cylinder part 21, at the end of the inner surface which is adjacent to the side cover 30 and which forms a boundary line of the rotation guide space Sr.
The axial displacement part 50a in the FPCB 50 can wind around the length changing unit 40 in a spiral or helical direction and can be inserted into the first slit 34. Moreover, if the base cover 60 is connected to the side cover 30, then the FPCB 50 can pass stably through the through-hole 84 which is formed by a combination of the first slit 34 and the second slit 64. The side cover 30 comprises a first combination part 36, and the base cover 60 comprises a second combination part 66. Thus, the side cover 30 is combined to the base cover 60 via the first combination part 36 and the second combination part 66.
As shown in FIG. 7, the FPCB 50 can comprise a rotation displacement part 50b which is disposed in a circumferential direction along the Z axis within the rotation guide space Sr, an axial displacement part 50a which is arranged inside the rectilinear guide spaces and which is in a tilted position toward the Z axis, a camera combiner 50d which is connected to the camera part, an exterior circuit board combiner 50e which is connected to an exterior circuit board, and a displacement connecting part 50c which connects the rotation displacement part and the axial displacement part.
The FPCB 50 can comprise an axial displacement part 50a, which, as discussed above, can be disposed in a plurality of layers and wound in a perpendicular direction within the rotation guide space Sr to the second guide cylinder part 22, such that strain dose not occur at the image pick-up device or at the main board when the length of the length changing unit is changed.
The first guide cylinder part 21 can comprise a plurality of protrusion guide parts 24 which guide the rotation displacement part 50b into the rotation guide space Sr and prevent them from being drawn outside, and which are formed at the end of the inner surface within the rotation guide space Sr that is adjacent to the side cover 30 of the rotation guide space Sr in the inner surface of the first guide cylinder part 21.
7. A mobile phone comprising: 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 to 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
19. The pop-up camera module of claim 13 wherein the side cover comprises a side which comprises a first slit and which is insertable into the base cover, and wherein the base cover comprises a second slit which is adjacent to the first slit, such that the first slit and the second slit collectively form a through-hole into which the FPCB inserts and through which the FPCB passes.
