Description

Optical unit, image stabilization unit and smartphone

The present invention relates to an optical unit, a shake correction unit and a smart phone.

When a still image or moving image is taken with a camera, the taken image may blur due to camera shake. Camera shake correction devices have been put into practical use to prevent such image blurring and enable clear photography. When the camera shakes, the camera shake correction device corrects the position and orientation of the camera module according to the shake, thereby eliminating blurring of the image.

An imaging signal of the camera shake correction device is output to the outside through a flexible circuit board (FPC). The flexible circuit board is movable according to the movement of the imaging element. For this reason, a flexible circuit that can be dynamically operated has been studied (see, for example, Patent Document 1). In the flexible circuit of Patent Literature 1, it is described that a local wide portion is provided at the bent portion of the linear portion.

A shake correction unit 200 includes an optical unit 10 . In this case, the optical unit 10 is mounted on the smart phone 300 . The optical unit 10 is installed in a smart phone 300 as an example.

In the smartphone 300 , light L enters from the outside through the optical unit 10 and a subject image is captured based on the light that enters the optical unit 10 . The optical unit 10 is used in the shake correction unit 200 that corrects the shake of the captured image when the smart phone 300 shakes. Note that the optical unit 10 may include an imaging device, and the optical unit 10 may include an optical member that transmits light to the imaging device. By including the optical unit 10 in the smartphone 300 , shake in the smartphone 300 can be corrected.

The optical unit 10 is preferably made small. As a result, the size of smartphone 300 itself can be reduced, or other components can be mounted in smartphone 300 without increasing the size of smartphone 300 .

Note that the application of the optical unit 10 is not limited to the smart phone 300, and can be used in various devices such as cameras and video cameras without particular limitations. For example, the optical unit 10 may be installed in camera-equipped mobile phones, photographing equipment such as drive recorders, or action cameras and wearable cameras installed in mobile objects such as helmets, bicycles, and radio-controlled helicopters.

Next, the optical unit 10 of the present embodiment and a shake correction unit 200 including the optical unit 10 will be described with reference to FIGS. 1 to 2B. 2A and 2B are schematic perspective views of the shake correction unit 200 of this embodiment. In FIG. 2B, the containing case 290 is omitted.

A portion of circuit board 100 and circuit board 270 extends from the interior of fixed body 220 and storage case 290 to the outside. The circuit board 100 extends in the −X direction with respect to the fixed body 220 and housing case 290 .

<Fixed body 220>
The fixed body 220 has an opening 220h. The movable body 210 is placed inside the fixed body 220 . Typically, movable body 210 is attached to the inside of fixed body 220 from the outside of fixed body 220 .

The stationary body 220 has a bottom portion 221 and side portions 222 . The bottom 221 extends in the XY plane. The bottom portion 221 has a thin plate shape. The side portion 222 protrudes from the bottom portion 221 in the +Z direction.

The side portion 222 has a first side portion 222a, a second side portion 222b, and a third side portion 222c. When the movable body 210 is attached to the fixed body 220 , the first side 222 a , the second side 222 b and the third side 222 c are positioned around the movable body 210 .

Typically, the support mechanism 230 is arranged on the bottom 221 of the stationary body 220 . Here, the support mechanism 230 supports the movable body 210 at a plurality of contact points arranged on the same circumference.

For example, the support mechanism 230 may be adhered to the fixed body 220 with an adhesive. Alternatively, the support mechanism 230 may be resin-molded integrally with the fixed body 220 . That is, the support mechanism 230 and the fixed body 220 may be a single member. When the support mechanism 230 is arranged on the fixed body 220 , the support mechanism 230 protrudes from the fixed body 220 toward the movable body 210 . Therefore, even when the movable body 210 swings with respect to the fixed body 220, the collision of the movable body 210 with the fixed body 220 can be suppressed.

<Swing mechanism 240>
The swing mechanism 240 swings the movable body 210 with respect to the fixed body 220 . The swing mechanism 240 swings the movable body 210 with respect to the fixed body 220 while the rotation center of the movable body 210 is fixed on the optical axis Pa.

The swing mechanism 240 swings the movable body 210 with respect to the fixed body 220 . The swing mechanism 240 allows the movable body 210 to swing with respect to the fixed body 220 with the center of rotation as a reference.

For example, the pitching, yawing, and rolling corrections of the movable body 210 are performed as follows. When the optical unit 10 shakes in at least one of the pitching, yawing, and rolling directions, the shake is detected by a magnetic sensor (Hall element) (not shown), and the rocking mechanism 240 is driven based on the result. to swing the movable body 210. A shake detection sensor (gyroscope) or the like may be used to detect shake of the optical unit 10 . A current is supplied to the swing mechanism 240 based on the shake detection result to correct the shake.

Note that a swinging mechanism other than the swinging mechanism 240 may swing the movable body 210 with respect to the fixed body 220 . The X-axis direction is a direction orthogonal to the optical axis direction Dp in which the optical axis Pa of the imaging device 20 extends, and serves as the axis of rotation in the yawing direction. The Y-axis direction is a direction orthogonal to the optical axis direction Dp in which the optical axis Pa of the imaging device 20 extends, and serves as an axis of rotation in the pitching direction. The Z-axis direction is parallel to the optical axis direction Dp and serves as the axis of rotation in the rolling direction.

In an optical device including the imaging device 20, if the optical device is tilted during shooting, the imaging device 20 is tilted and the captured image is disturbed. The shake correction unit 200 corrects the tilt of the imaging device 20 based on the acceleration, angular velocity, shake amount, and the like detected by a detection means such as a gyroscope, in order to avoid disturbance of the captured image. In this embodiment, the shake correction unit 200 rotates in a rotation direction (yawing direction) about the X axis, a rotation direction (pitching direction) about the Y axis, and a rotation direction (rolling direction) about the Z axis. The tilt of the imaging device 20 is corrected by rocking (rotating) the movable body 210 in the direction).

The holder 214 holds the imaging element 20 and the wiring board 110 of the circuit board 100 .

The holder 214 has a bottom portion 214a and side portions 214b. The support mechanism 230 supports the bottom portion 214 a of the holder 214 .

The swing mechanism 240 swings the movable body 210 with respect to the fixed body 220 . The swing mechanism 240 includes a first swing mechanism 242 , a second swing mechanism 244 and a third swing mechanism 246 . The first rocking mechanism 242, the second rocking mechanism 244, and the third rocking mechanism 246 respectively rock the movable body 210 relative to the fixed body 220 around different axes.

The first swing mechanism 242 swings the movable body 210 with respect to the fixed body 220 . The first swing mechanism 242 swings the movable body 210 around the X axis while the rotation center of the movable body 210 is fixed within the XZ plane. Here, the X-axis direction is the axis of rotation in the yawing direction. The first swing mechanism 242 is positioned on the +Y direction side with respect to the movable body 210 .

The first swing mechanism 242 includes a magnet 242a and a coil 242b. The magnet 242a is magnetized such that the magnetic poles of the surface facing radially outward are different with respect to the magnetic polarization line extending along the X-axis direction.

The magnet 242a is arranged on the +Y direction side of the side portion 214b of the holder 214 . Coil 242 b is disposed on circuit board 270 . The coil 242b is located in a through-hole passing through the first side portion 222a of the fixed body 220. As shown in FIG.

By controlling the direction and magnitude of the current flowing through coil 242b, the direction and magnitude of the magnetic field generated from coil 242b can be changed. Therefore, the interaction between the magnetic field generated by the coil 242b and the magnet 242a causes the first swinging mechanism 242 to swing the movable body 210 around the X axis.

The second swing mechanism 244 swings the movable body 210 with respect to the fixed body 220 . The second swing mechanism 244 swings the movable body 210 around the Y-axis while the rotation center of the movable body 210 is fixed within the YZ plane. Here, the Y-axis direction is the axis of rotation in the pitching direction. The second rocking mechanism 244 is located on the −X direction side with respect to the movable body 210 .

The second swing mechanism 244 includes a magnet 244a and a coil 244b. The magnet 244a is magnetized such that the magnetic poles of the surface facing radially outward are different with respect to the magnetic polarization line extending along the Y-axis direction. One end of the magnet 244a along the Z-axis direction has one polarity, and the other end has the other polarity.

The magnet 244a is arranged on the side portion 214b of the holder 214 in the -X direction. Coil 244 b is disposed on circuit board 270 . The coil 244b is located in a through-hole passing through the second side portion 222b of the fixed body 220. As shown in FIG.

By controlling the direction and magnitude of the current flowing through coil 244b, the direction and magnitude of the magnetic field generated from coil 244b can be changed. Therefore, the interaction between the magnetic field generated by the coil 244b and the magnet 244a causes the second swinging mechanism 244 to swing the movable body 210 around the Y-axis.

The third swing mechanism 246 swings the movable body 210 with respect to the fixed body 220 . Specifically, the third swing mechanism 246 swings the movable body 210 around the Z-axis while the rotation center of the movable body 210 is fixed within the XZ plane. Here, the Z-axis direction is parallel to the optical axis Pa and serves as the axis of rotation in the rolling direction. The third rocking mechanism 246 is located on the −Y direction side with respect to the movable body 210 .

The third swing mechanism 246 includes a magnet 246a and a coil 246b. The magnet 246a is magnetized such that the magnetic poles of the surface facing radially outward are different with respect to the magnetization polarization line extending along the Z-axis direction. One end of the magnet 246a along the X-axis direction has one polarity, and the other end has the other polarity.

The magnet 246a is arranged on the side portion 214b of the holder 214 in the -Y direction. Coil 246 b is located on circuit board 270 . The coil 246b is located in a through-hole passing through the third side portion 222c of the fixed body 220. As shown in FIG.

By controlling the direction and magnitude of the current flowing through coil 246b, the direction and magnitude of the magnetic field generated from coil 246b can be changed. Therefore, the interaction between the magnetic field generated by the coil 246b and the magnet 246a causes the third swinging mechanism 246 to swing the movable body 210 around the Z axis.

In this specification, magnet 242a, magnet 244a and magnet 246a may be collectively referred to as magnet 240a. Also, in this specification, the coil 242b, the coil 244b, and the coil 246b may be collectively referred to as the coil 240b.

The swing mechanism 240 has a magnet 240 a provided on the movable body 210 and a coil 240 b provided on the fixed body 220 . Here, magnet 240 a is arranged on movable body 210 and coil 240 b is arranged on fixed body 220 . However, magnet 240 a may be arranged on fixed body 220 and coil 240 b may be arranged on movable body 210 . Thus, one of magnet 240 a and coil 240 b may be arranged on one of movable body 210 and fixed body 220 , and the other of magnet 240 a and coil 240 b may be arranged on the other of movable body 210 and fixed body 220 . By controlling the direction and magnitude of the current flowing through coil 240b, the direction and magnitude of the magnetic field generated from coil 240b can be changed. Therefore, the swing mechanism 240 can swing the movable body 210 by the interaction between the magnetic field generated by the coil 240b and the magnet 240a.

The optical unit 10 further includes a magnetic body 242c, a magnetic body 244c and a magnetic body 246c.

A gap G is provided between the first extended portion 151 and the second extended portion 152 . The gap G allows the first extended portion 151 and the second extended portion 152 to be easily bent with respect to the first linear portion 122 and the second linear portion 124, respectively.

The first extended portion 151 and the second extended portion 152 are symmetrical with respect to the first bent portion 123 . Accordingly, the first extension portion 151 and the second extension portion 152 can be efficiently connected.

The first direction D1 in which the first straight portion 122 extends is perpendicular to the second direction D2 in which the second straight portion 124 extends. As a result, it is possible to efficiently prevent the bent shape of the first straight portion 122 and the second straight portion 124 of the circuit board 100 from collapsing.

The circuit board 100 has a first opposing extension 151a and a second opposing extension 152a.

It bends and extends with respect to the second straight portion 124 . The second opposing extension 152a is connected to the first opposing extension 151a. Thereby, the balance of elastic resistance can be maintained at both ends 122a to 124b in the width direction (Z direction) of the first linear portion 122 and the second linear portion .
