Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] Embodiments of the present invention relate to a small-sized
camera lens module mounted on the front or rear of the main body of
a mobile communication terminal and used in various photographing
modes.
[0003] 2. Description of the Related Art
[0004] Recently, at least one light, thin, short, and small camera
lens module is adopted in a mobile communication terminal, such as
a tablet PC or smart phone that is generalized with the recent
development of a mobile communication technology. In particular,
there is a user's high-capacity and high-performance demand for the
camera lens module adopted in the mobile communication terminal.
Furthermore, the camera lens module is being developed in the
direction advantageous for a small size while maintaining its high
capacity and high performance.
[0005] A small camera lens module adopted in a mobile communication
terminal is equipped with an auto-focusing function and a digital
zoom function and also equipped with a stabilizer function so that
it is faithful to its camera function. In general, a known camera
lens module includes a lens, a lens driving unit configured to move
the lens in the direction of the optical axis and provide a movable
force for focus control, and an image sensor configured to
photograph light incident through the lens and convert the
photographed light into an image signal. The camera lens module is
configured to perform focusing on a subject for photographing by
automatically controlling the distance between the lens and the
image sensor.
[0006] The lens driving unit of the camera lens module that
implements auto-focusing may be divided into a voice coil motor
(VCM) type using an interaction principle between a magnetic field
and an electric field and an encoding type in which the location of
the lens is automatically controlled in response to the detection
of the sensor. In a method of implementing a focusing function in
the VCM type camera lens module, a VCM is chiefly used as a driving
source. The VCM includes a magnet configured to generate a magnetic
force and a coil supplied with an electric current and moves a lens
barrel by a force generated by the interaction between an electric
field and a magnetic field. Likewise, the encoding type camera lens
module includes a magnet and a coil supplied with an electric
current and provides a movable force.
[0007] For example, a conventional small-sized auto-focusing camera
lens module mounted on a mobile communication terminal is disclosed
in "Korean Patent Application No. 2010-106811", "Korean Patent
Application No. 2009-83613", "Korean Patent Application No.
2012-85890", and "Korean Patent Application No. 2010-71948."
SUMMARY OF THE INVENTION

additionally configured in the camera lens module depending on
performance of a terminal. If such driving units are reduced in
size and the small-sized driving units are disposed in empty spaces
of the camera lens module, a reduction in the size of the camera
lens module can be achieved.

DETAILED DESCRIPTION
[0058] Hereinafter, exemplary embodiments of the present invention
are described in detail with reference to contents described in the
accompanying drawings. However, the present invention is not
limited to or restricted by the exemplary embodiments. The same
reference numeral suggested in each drawing denotes an element
having substantially the same function.
[0059] Terms including ordinal numbers, such as the first and the
second, may be used to describe various elements, but the elements
are not restricted by the terms. The terms are used to only
distinguish one element from the other element. For example, in
various embodiments of the present invention, a first element may
be named a second element. Likewise, a second element may be named
a first element. The terms used in this application have been used
to only describe specific embodiments and are not intended to
restrict the present invention. An expression of the singular
number includes an expression of the plural number unless clearly
defined otherwise in the context.
[0060] Furthermore, in describing embodiments of the present
invention, a term "substantially" does not mean that a cited
characteristic, parameter, or value must be accurately achieved and
may be generated to the extent that an effect to be provided by a
deviation, change, or characteristic, including a tolerance, an
error of measurement, an accuracy limit in measurement, and other
factors known to those skilled in the art, is not excluded.
[0061] The disposition of driving units mounted on a camera lens
module in accordance with embodiments of the present invention is
described below with reference to FIGS. 1 to 3. In describing an
embodiment of the present invention, a three-dimensional X/Y/Z
coordinate system has been illustrated. In this case, a "Z axis"
means a direction perpendicular to the camera lens module and the
direction of an optical axis in which a lens barrel moves. An "X
axis" means a direction horizontal to the camera lens module (i.e.,
a direction perpendicular to the optical axis), and a "Y axis"
means a direction vertical to the camera lens module (i.e., a
direction vertical to the optical axis and perpendicular to the X
axis).
[0062] Furthermore, a mobile communication terminal on which a
camera lens module in accordance with an embodiment of the present
invention is mounted is only a common term. An embodiment of the
present invention may also be applied to any one of a mobile phone,
a palm-sized personal computer (PC), a personal communication
system (PSC), a personal digital assistant (PDA), a hand-held PC
(HPC), a smart phone, a local area network (LAN) terminal, a laptop
computer, and a tablet PC. Accordingly, the term "mobile
communication terminal" is not intended to limit the application of
the present invention to any device of a specific type. Since a
camera lens module in accordance with an embodiment of the present
invention is advantageous for a small size, it may be properly
mounted on a mobile communication terminal that belongs to mobile
communication terminals and that can be easily held in one hand,
such as a smart phone.
[0063] Driving units mounted on a camera lens module in accordance
with various embodiments of the present invention may include an
auto-focusing driving unit, an optical image stabilizer driving
unit, and an optical element driving unit selectively or in
combination. For example, only the auto-focusing driving unit may
be mounted on the camera lens module, only the auto-focusing
driving unit and the optical image stabilizer driving unit may be
mounted on the camera lens module, or all of the auto-focusing
driving unit, the optical image correction unit, and the optical
element driving unit may be mounted on the camera lens module
depending on performance of the camera lens module.
[0064] Furthermore, one or a plurality of the auto-focusing driving
units may be mounted on the camera lens module, one or a plurality
of the optical image stabilizer driving units may be mounted on the
camera lens module, and one or a plurality of the optical element
driving units may be mounted on the camera lens module.
[0065] All of the driving units may be mounted on a camera lens
module in accordance with various embodiments of the present
invention depending on performance of the camera lens module. For a
reason of a reduction in size, the auto-focusing driving unit is
essentially mounted on the camera lens module, but the optical
image stabilizer driving unit or the optical element driving unit
may be selectively mounted on the camera lens module through a
selective combination with the auto-focusing driving unit. The
auto-focusing driving unit, the optical image stabilizer driving
unit, and the optical element driving unit are efficiently disposed
in empty spaces on the basis of a lens barrel that moves in the
optical axis of the camera lens module.
[0066] FIG. 1 is a plan view schematically illustrating the
disposition of the driving units of a camera lens module in
accordance with a first embodiment of the present invention. The
disposition of the driving units of the camera lens module in
accordance with the first embodiment of the present invention is
described below with reference to FIG. 1.
[0067] The camera lens module includes a base 10, an auto-focusing
driving unit 11, and an optical element driving unit 12. The base
10 may have a polyhedron shape, approximately a rectangular shape.
The base 10 includes a top surface, a bottom surface, and 4 side
surfaces. The four side surfaces hereinafter refer to a first side
surface 101, a second side surface 102, a third side surface 103,
and a fourth side surface 104. The first side surface 101 is
disposed to face the second side surface 102 in parallel to the
second side surface 102 and disposed to neighbor the third and the
fourth side surfaces 103, 104 in a direction perpendicular to the
third and the fourth side surfaces 103, 104. The second side
surface 102 is disposed to face the first side surface 101 in
parallel to the first side surface 101 and disposed to neighbor the
third and the fourth side surfaces 103, 104 in a direction
perpendicular to the third and the fourth side surfaces 103, 104.
The third side surface 103 is disposed to face the fourth side
surface 104 in parallel to the fourth side surface 104 and disposed
to neighbor the first and the second side surfaces 101, 102 in a
direction perpendicular to the first and the second side surfaces
101, 102. The fourth side surface 104 is disposed to face the third
side surface 103 in parallel to the third side surface 103 and
disposed to neighbor the first and the second side surfaces 101,
102 in a direction perpendicular to the first and the second side
surfaces 101, 102.
[0068] A lens barrel 15 moving in the direction of the optical axis
is placed at the center of the base 10. The lens barrel 15 is moved
in the direction of the optical axis by the driving of the
auto-focusing driving unit 11, so a focal distance from an image
sensor (not illustrated) is controlled. Furthermore, the lens
barrel 15 can improve a camera function because a lens (not
illustrated) is open or closed or a filter having an additional
function is placed on the lens by the driving of the optical
element driving unit 12.

optical axis.
[0079] FIG. 3 is a plan view schematically illustrating the
disposition of the driving units of a camera lens module in
accordance with a third embodiment of the present invention. The
disposition of the driving units of the camera lens module in
accordance with the third embodiment of the present invention is
described below with reference to FIG. 3.
[0080] As illustrated in FIG. 3, the camera lens module in

Furthermore, the auto-focusing driving unit 31 and the optical
element driving unit 32 are disposed to stand opposite to each
other. A single auto-focusing driving unit 31 is disposed, and a
single optical element driving unit 32 is also disposed.
[0082] FIG. 4 is a plan view schematically illustrating the
disposition of the driving units of a camera lens module in
accordance with a fourth embodiment of the present invention. The
disposition of the driving units of the camera lens module in
accordance with the fourth embodiment of the present invention is
described below with reference to FIG. 4.
[0083] As illustrated in FIG. 4, the camera lens module in
accordance with the fourth embodiment of the present invention may
include a base 30-1, an auto-focusing control unit 31-1 disposed in
the base 30-1, an optical element driving unit 32-1, and first and
second optical image stabilizer driving units 33-1, 34-1. The base
30-1 includes corner areas, that is, four empty spaces. The four
corner areas include a first corner area 301-1, a second corner
area 302-1, a third corner area 303-1, and a fourth corner area
304-1. The first corner area 301-1 is disposed in a direction
perpendicular to the second corner area 302-1. The third corner

corner area 304-1. The first corner area 301-1 stands opposite to
the third corner area 303-1 in a diagonal direction and the second
corner area 302-1 stands opposite to the fourth corner area 304-1
in a diagonal direction, on the basis of an optical axis.
[0084] In the camera lens module, the auto-focusing driving unit
31-1 is disposed in the first corner area 301-1 of the base 30-1,
and the optical element driving unit 32-1 is disposed in the second
corner area 302-1 disposed in the direction perpendicular to the
first corner area 301-1. The auto-focusing driving unit 31-1 faces
a lens barrel 35, and the optical element driving unit 32-1 also
faces the lens barrel 35. Furthermore, the auto-focusing driving
unit 31-1 is adjacent to the optical element driving unit 32-1 in a
perpendicular direction. A single auto-focusing driving unit 31-1
is disposed, and a single optical element driving unit 32-1 is also
disposed.
[0085] Furthermore, in the camera lens module of the fourth
embodiment, the first and the second optical image stabilizer
driving units 33-1, 34-1 may be disposed in the third and the
fourth corner areas 303-1, 304-1 that respectively stand opposite
to the first and the second corner areas 301-1, 302-1. The first
and the second optical image stabilizer driving units 33-1, 34-1
are disposed to face the lens barrel 35 and area adjacent to each
other in a perpendicular direction.
[0086] Alternatively, only one optical image stabilizer driving
unit may be disposed in any one of the third and the fourth corner
areas 303-1, 304-1 of the base 30-1. In other words, in the camera
lens module of the fourth embodiment, only the first optical image
stabilizer driving unit is disposed in the third corner area 303-1
and the second optical image stabilizer driving unit may not be
disposed, or only the second optical image stabilizer driving unit
is disposed in the fourth corner area 304-1 and the first optical
image stabilizer driving unit may not be disposed in the third
corner area 303-1.
[0087] In a modified embodiment of the present invention, in the
camera lens module, an optical image stabilizer driving unit may be
disposed instead of the auto-focusing driving unit 31-1, and first
and second auto-focusing driving units may be disposed instead of
the first and the second optical image stabilizer driving units
33-1, 34-1. That is, the auto-focusing driving unit 31-1 and the
first and the second optical image stabilizer driving units 33-1,
34-1 may be respectively substituted with the optical image
stabilizer driving unit and the first and the second auto-focusing
driving unit.
[0088] The auto-focusing driving unit 31-1 is disposed to stand
upright in the direction of the optical axis. The first and the
second optical image stabilizer driving units 33-1, 34-1 are also
disposed to stand upright in the direction of the optical axis. The
optical element driving unit 32-1 is disposed to stand upright in
the direction of the optical axis.
[0089] The disposition of the driving units of the camera lens
modules in accordance with some embodiments of the present
invention has been described by taking into consideration a
reduction in the size. An optical element assembly including an
optical element driving unit mounted on a camera lens assembly in
accordance with embodiments of the present invention is described
below with reference to some drawings.
[0090] The configuration of a camera lens assembly 60 in accordance
with an embodiment of the present invention is described below with
reference to FIGS. 5 to 17.
[0091] As illustrated in FIGS. 5 to 8, the camera lens assembly 60
may include an auto-focusing assembly 40 and an optical element
assembly 50 coupled to the auto-focusing assembly 40. The optical
element assembly 50 is coupled to the auto-focusing assembly 40 on
the basis of the center of an optical axis, thereby completing the
camera lens module 60 of FIG. 5. The auto-focusing assembly 40 is
named because an auto-focusing driving unit (not illustrated) is
installed on the other side surface 410 of the base 41. If an
optical image stabilizer driving unit (not illustrated) is
installed on the other side surface 410 of the base 41, the
auto-focusing assembly 40 may be denoted as an optical image
stabilizer assembly.
[0092] Furthermore, an auto-focusing driving unit may be mounted on
the other side surface 410 of the auto-focusing assembly 40, and
optical image stabilizer driving units may be disposed in spaces
within front and rear side surfaces 412, 414.
[0093] The assembly of the modules of the camera lens module 60 is
completed by coupling between the base 41 of the auto-focusing
assembly 40 and the base 51 of the optical element assembly 50. A
filter cover 52 is coupled to the top surface of the camera lens
assembly 60. A coupling pin to be described later is exposed to
some edge of the filter cover 52. A lens barrel 42 is moved in the
direction of the optical axis by an auto-focusing driving unit (not
illustrated), so the focal distance between a lens and an image
sensor (illustrated in FIG. 6) is controlled.
[0094] The configuration of the optical element assembly 50 in
accordance with an embodiment of the present invention is described
below with reference to FIGS. 9 to 12. The optical element assembly
50 is disposed in parallel to one or a plurality of one side
surfaces within a camera lens module as already described above.
The optical element driving unit of the optical element assembly 50
may be disposed to face any one side surface not in the corner area
of the camera lens module because it has an approximately
flat-plate shape (i.e., a rectangular flat shape having a specific
thickness). Furthermore, an auto-focusing driving unit (not
illustrated) may be installed on the other side surface opposite
one side surface in which the optical element driving unit has been
installed.
[0095] The optical element assembly 50 includes an optical element
base 51, the optical element driving unit, and an optical element
unit. The optical element may be a filter. The optical element base
51 is a basic support coupled to an auto-focusing base. The optical
element driving unit and the optical element unit are disposed in
the optical element base 51. The optical element driving unit is
mounted on the optical element base 51 in such a way as to stand
upright in the direction of an optical axis. The optical element
unit is disposed in parallel to the top surface of the optical
element base 51 and mounted in such a way as to be rotated. An
opening 516 having a specific diameter is formed in the top surface
of the optical element base 51. The opening 516 is a space where
the lens barrel is placed.
[0096] The optical element driving unit is mounted on one side
surface of the optical element base in parallel to one side surface
of the camera lens module, and provides a force that drives the
optical element unit. That is, the optical element driving unit is
mounted so that it operates in conjunction with the optical element
unit, thus providing a force that rotates the optical element unit
around a hinge h.
[0097] The optical element driving unit includes yokes y1, y2, a
coil C, a movable magnet m, and guides g1, g2. The optical element
driving unit functions to provide a force that rotates the optical
element unit using an electromagnetic force generated between the
coil C and the movable magnet m. When the movable magnet m is
reciprocated left and right in response to the electric current of
the coil C, the optical element driving unit rotates the optical
element unit. The coil C is a stator, and the movable magnet m is a
rotor. The optical element driving unit is a driving source mounted
on one side surface of the camera lens module in such a way as to
stand upright in the direction of the optical axis and configured
to provide a force for moving the optical element unit disposed in
parallel to the top surface of the optical element base 51, that
is, disposed in parallel to a surface perpendicular to the optical
axis (i.e., an X-Y plane).
[0098] The optical element base 51 is a stator, and has the yokes
y1, y2, the coil C, and the guides g1, b1; g2, b2 mounted on one
side surface thereof. A coil seating unit 510 having the center
recessed is placed on the one side surface of the optical element
base 51. Guides seating units 512, 514 are disposed on both sides
of the coil seating unit 510. One (illustrated in FIG. 19) or a
plurality of yokes y1, y2 is disposed on the bottom surface of the
coil seating unit 510.
[0099] The yokes y1, y2 may be made of a magnetic materials and a
metal material in order to provide an attractive force with the
movable magnet m. The yokes include first and second yokes y1, y2
that are symmetrical to each other on the bottom surface of the
coil seating unit 510, disposed to face the movable magnet m, and
disposed in parallel. The first yoke y1 has a longish rectangular
shape having a thickness, and is disposed on the bottom surface of
the coil seating unit 510 in such a way as to extend in the
direction of the optical axis. The second yoke y2 has the same
shape as the first yoke y1, and is disposed to be symmetrical to
the first yoke y1 next to the first yoke y1 in such a way as to
extend in the direction of the optical axis.
[0100] The guide seating units 512, 514 are formed in the optical
element base 51. The first and the second guides g1, b1; g2, b2 are
respectively installed in the guide seating units 512, 514. The
first and the second guides g1, b1; g2, b2 are mounted for a smooth
movement of a magnet transfer housing 55 to be described later. In
particular, when the first and the second guides g1, b1; g2, b2 are
closely attached to the magnet transfer housing 55, they function
as bearings and support a smooth movement of the magnet transfer
housing 55. The magnet transfer housing 55 performs a rolling
operation by the first and the second guides g1, b1; g2, b2.
[0101] The guides include the first and the second guides g1, b1;
g2, b2 on both sides of the first and the second yokes y1, y2 or on
both sides of the coil C. The first and the second guides g1, b1;
g2, b2 support the magnet transfer housing 55. A pair of the first
guides g1, b1 are configured and placed in the guide seating unit
512 on upper and lower sides thereof. The second guides g2, b2 are
disposed symmetrically to the first guides g1, b1 on the basis of
the coil C and disposed in the guide seating unit 514. The first
and the second guides include respective ball bearings b1, b2. The
ball bearings b1, b2 support the rolling operation of the magnet
transfer housing 55.
[0102] The movable magnet m has an approximately rectangular shape
having a thickness and a flat plate shape. The movable magnet m is
safely accommodated in the magnet transfer housing 55a. The movable
magnet m linearly reciprocates left and right (i.e., in the X-axis
direction) and drives the optical element unit while maintaining a
specific distance from the coil C through cooperation with the coil
C. The distance between the coil C and the movable magnet m is
maintained by the ball bearings b1, b2.
[0103] The magnet transfer housing 55 is a flat plate-shaped
housing for accommodating the movable magnet m. The magnet transfer
housing 55 moves in parallel on the coil C in the state in which
the movable magnet m has been included in the magnet transfer
housing 55. The magnet transfer housing 55 moves through a rolling
operation in the state in which it has a direct contact with the
ball bearings b1, b2 and linearly moves left and right (i.e., in
the X-axis direction).
[0104] A coupling pin 550 coupled to the optical element unit is
provided at the top corner of the magnet transfer housing 55 on one
side thereof. When the magnet transfer housing 55 moves, the
optical element unit performs a rotary motion around the hinge h in
conjunction with the coupling pin 550. P denotes a printed circuit
board (PCB) or flexible printed circuit board (FPCB) for
electrically connecting the coil C to an external power source.
[0105] As illustrated in FIGS. 10 to 12, the coil C, the movable
magnet m, and the magnet transfer housing 55 are mounted on one
side surface of the optical element base 51. A specific gap is
present between the movable magnet m and the magnet transfer
housing 55, and the exterior of the coil C. The gap is provided by
the ball bearings b1, b2. Furthermore, an attractive force between
the magnet transfer housing 55 and the yokes y1, y2 is made
possible because the yokes are made of a magnetic or metallic
material. The reciprocation of the magnet transfer housing 55 in
the X-axis direction is caused by an electromagnetic force
generated when an electric current is applied to the coil C. The
movable magnet m may be one-sidedly disposed on one side of the
coil C and may be one-sidedly disposed on the other side of the
coil C depending on whether a (+) pole or a (-) pole is applied to
the coil C.
[0106] The driving of the optical element assembly is described
below with reference to FIGS. 13 to 16. In the first mode of the
camera lens module, the first filter 530 of a filter blade 53 is
disposed at the center of the optical axis. That is, the first
filter 530 is placed on the lens of a lens barrel (not
illustrated). Such a state is illustrated in FIGS. 13 and 15. The
movable magnet m is one-sidedly placed slightly to the left on the
basis of the coil C.
[0107] When the first mode switches to a second mode, the direction
of an electric current applied to the coil C is reversed, and thus
the movable magnet m linearly moves to the right. Next, the filter
blade 53 coupled to a coupling pin 550 is counterclockwise rotated,
so the second filter 532 is disposed at the center of the optical
axis. That is, the second filter 532 is placed on the lens of the
lens barrel (not illustrated).
[0108] As a result, when the movable magnet m linearly moves, the
coupling pin 550 also linearly moves, but the filter blade 53
rotates around the hinge h. Accordingly, the first filter 530 or
the second filter 532 is placed at the center of the optical axis
depending on the first or second mode.
[0109] An optical element that forms the optical element unit in
accordance with an embodiment of the present invention, that is,
the filter blade 53, is described below with reference to FIG. 17.
The filter blade 53 may be called a multi-filter because it
includes the two first and the second filters 530 and 532.
Furthermore, any one of the first filter 530 and the second filter
532 may be deleted, and the deleted filter may be responsible for a
shutter. Furthermore, the filter blade 53 may include at least
three optical filters. The first and the second filters 530 and 532
are provided in specific areas of the filter blade and disposed in
parallel.
[0110] The first filter 530 may be formed of a visible ray filter,
and the second filter 532 may be formed of an infrared filter.
Alternatively, the first and the second filters 530 and 532 may be
configured in various ways depending on a photographing mode. For
example, various optical filters may be used instead of the first
filter 530 or the second filter 532. For example, the optical
filters may include a bandpass filter, an ND filter, a PL filter,
and a color filter. Furthermore, the filter blade 53 may include
various lenses having optical zoom-in/out functions instead of the
optical filter.
[0111] If the first filter 530 is formed of a visible ray cut-off
filter and disposed at the center of the optical axis, the camera
lens module may be applied to a common mode. If the second filter
532 is formed of an infrared (IR) band-pass filter and disposed at
the center of the optical axis, the camera lens module may be
applied to a security or authentication mode because the iris can
be recognized. A first opening 531 into which the coupling pin is
inserted is provided in an area of the filter blade 53 on one side
thereof. A second opening 533 to which the hinge is coupled is
provided in the filter blade 53. The first opening 531 is lengthily
formed, so the coupling pin moves within the first opening 531.
[0112] Referring to FIG. 18, an optical element assembly in
accordance with an embodiment of the present invention may further
include a position sensor. A position sensor S1 may be disposed in
the internal space of the coil C or a position sensor S2 may be
disposed near the coil C on the board P on which the coil C has
been mounted. Each of the position sensors S1 and S2 may detect the
location of the movable magnet and output a detection signal. The
position sensor S1 disposed within the coil C or the position
sensor S2 disposed near the coil C may be used by taking into
consideration a mounting space.
[0113] Referring to FIG. 19, a yoke in accordance with an
embodiment of the present invention may include a single yoke y3.
The single yoke y3 may be provided in the optical element base 51
in such a way as to stand upright in the direction of the optical
axis. The single yoke y3 may be disposed at the bottom of the board
P including the coil C in such a way as to be depressed.
[0114] Referring to FIGS. 20 and 21, first and second yokes y4, y5
in accordance with an embodiment of the present invention may be
provided in the guide seating surfaces 512, 514 of the optical
element base 51 not in the coil seating surfaces of the optical
element base 51. Furthermore, the first and the second yokes y4,
y5, together with ball bearings b4, b5, may be provided in the
guide seating surfaces 512, 514. The first yoke y4 and the first
ball bearing b4 may be disposed on one side of the coil C, and the
second yoke y5 and the second ball bearing b5 may be disposed on
the other side of the coil C.
[0115] Furthermore, the first and the second yokes y4, y5 may be
respectively disposed inside the first and the second ball bearings
b4, b5. Such a disposition state of the first and the second yokes
y4, y5 is illustrated in FIG. 20. Furthermore, the first and the
second yokes y6, y7 may be respectively disposed outside the first
and the second ball bearings b6 and b7. Such a disposition state of
the first and the second yokes y6, y7 is illustrated in FIG. 21.
The inside refers to a direction that becomes close to the coil C,
and the outside refers to a direction that becomes distant from the
coil C.
[0116] Referring back to FIG. 9, the elements of the optical
element driving unit are seated in one side surface of the optical
element base 51 by an outer block side cover 56. The outer block
side cover 56 is configured to have a length enough to accommodate
the moving distance of the magnet transfer housing 55. The elements
of the optical element unit are safely seated on the top surface of
the optical element base 51 by the filter cover 52. Furthermore,
the filter blade 53 performs a safe rotary movement on the top
surface of the optical element base 51 by a filter guide plate 54
without intervention.
[0117] As described above, the camera lens module in accordance
with an embodiment of the present invention is advantageous for a
small-size design because the optical element driving unit is
configured to have an approximately flat plate shape, mounted to
face one side surface of the camera lens module, and disposed to
face the auto-focusing control unit or the optical image stabilizer
driving unit.
[0118] Furthermore, the camera lens module in accordance with an
embodiment of the present invention is advantageous for a
small-size design because the optical element driving unit is
configured to have an approximately flat plate shape, disposed in a
corner area of the camera lens module in such a way as to face the
lens barrel, and disposed to face the auto-focusing control unit or
the optical image stabilizer driving unit.
[0119] Furthermore, the camera lens module in accordance with an
embodiment of the present invention is convenient in various
photographing mode because it includes the multi-filter and is
effective in mobile phone security authentication because it can
recognize the iris.
[0120] Although the embodiments of the present invention have been
illustrated and described, those skilled in the art will understand
that the present invention may be modified in various ways in its
form and details without departing from the spirit and scope of
embodiments, such as the attached claims and those defined by their
equivalents.
