The invention relates to a lens sheet driving device for moving a lens sheet along an optical axis, an image pickup device using the lens sheet driving device, and a lens sheet position adjustment thereof. method. Eighth [Prior Art] Conventionally, an image pickup device such as a small camera uses a DC motor (Dc price) or a steppmg motor as an actuator for moving the lens sheet in the optical axis direction. However, in recent years, the use of the image pickup device in the mobile device has increased, and the demand for miniaturization and light weight of the image pickup device has increased. Accordingly, there has been a demand for miniaturization and light weight of the lens sheet drive device. In the past, in place of the DC motor, a so-called voice coil motor (We C01l motor) in which a coil is disposed in a magnetic circuit formed by a magnet or a yoke has been used. In the lens sheet drive of the voice coil motor, the lens frame of the movable portion is made lighter as much as possible, so that the coil is wound through the one frame and the magnet and the yoke are disposed in the fixing portion (for example, Specifically, it is proposed to wrap the coil so as to surround the entire circumference of the lens frame (for example, 'refer to the patent document or the winding coil provided in the projection of the lens frame, etc.). (For example, refer to Patent Documents 2 and 3) On the other hand, it is proposed to eliminate the trouble of wiring when winding a coil in a lens frame of a movable portion, and fix the magnet in the lens frame and roll it in a fixed portion. A method of winding a coil (for example, 'refer to Patent Document 4). In addition, 3) 7266 1281052 also proposes a guide shaft for guiding the lens frame in the optical axis direction as a part of a magnetic vehicle to simplify the device configuration. (For example, refer to Patent Document 5) 专利 [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei 6-201975 (pages 3 to 4, pages 10 to 12) [Patent Document 2] 曰本特开 2000-137156 Bulletin (Page 4, Figure 2) [Patent Document 3] [Patent Document 4] [Patent Document 4] Japanese Patent Laid-Open Publication No. Hei 2〇〇〇3:21475 (3rd page, 2nd drawing) ' [Patent Document 5]曰本特开昭 62_88147号 (Page 3, Fig.) ' [Summary of the Invention] [Problems to be Solved by the Invention] m, % 办 衣 仃 仃 仃 仃 仃 机器 液晶 液晶 液晶 液晶 液晶 液晶Although it is disposed adjacent to the camera (image pickup device), the device 2 has a direction in which the display portion is adjacent to the image pickup device (for example, the degree is shortened as much as possible.

Therefore, there is still a problem that the size of the device of the lens sheet driving device becomes large. As disclosed in Patent Document 4, when the magnet is fixed to the lens frame of the movable portion, the weight of the lens frame is increased, so that the current required to drive the lens frame becomes large. Moreover, since the weight of the lens sheet is increased, the frictional resistance of the guide shaft and the bearing portion for guiding the lens frame is increased, so that the required driving current is obtained. The bigger problem exists. In the case disclosed in Patent Document 5, when the "sleeve" that guides the lens frame to the optical axis direction is used as the yoke of the magnetic circuit, the coil is placed so as to surround the guide shaft, but the lens piece and the coil are arranged. Without interfering with each other, it is necessary to ensure a long distance between the guide shaft and the lens sheet, thereby causing a problem that the dimension of the lens frame length becomes long. In order to solve the above problems, the present invention aims to reduce the size and weight of the lens sheet driving device. [Means for Solving the Problem] _ ', the lens sheet driving device of the invention includes a lens group, and includes a first lens sheet and a second lens sheet having a larger outer diameter than the 34th i-th lens sheet a lens frame for holding the lens group and having a guide hole substantially parallel to an optical axis direction of the lens group; a fixing portion slidably fastened to the guide hole and including a lens frame a guide shaft guided in the optical axis direction; a coil is fixed to the lens frame so as to surround the guide shaft; and the iron is fixed between the upper 34 guide shaft and the coil The fixing unit; the magnetic vehicle, together with the guide shaft, constitutes a branch including the magnet, and the coil is disposed adjacent to a portion of the first lens sheet for holding the 311266 7 '1281052 lens frame.

As a result, the lens sheet driving device can be reduced by 0 in the x direction. That is, it is possible to reduce the size and weight of the lens month driving device H. In the present embodiment, the coil holding portion 34 is formed adjacent to the small warp frame portion 31. Therefore, the coil 5 can be disposed in comparison with the case where the coil holding portion 34 is formed adjacent to the large-diameter frame portion 32 in the shape of 317266 12 1281052. It is closer to the position where the light is pumped a. Further, since one portion of the magnet 7 is 4 in the Z direction and the large-diameter frame portion 32, the coil 5 can be disposed at a position closer to the optical axis A. As a result, the size of the sheet driving device 1kY direction can be further reduced, and the pair of magnets 7 are disposed so as to sandwich the coil 5 in the χ direction, so that the shape of the lens sheet driving device 1 can be further changed. Shrink: Furthermore, since the magnetic sheet 8 is attached to the lens sheet 3, it is possible to obtain the original force of the lens 3 to return to the predetermined position (the shift of the _ζ direction 10) when the power is not supplied. (4)), etc., the lens sheet driving the government 10 can be further miniaturized. Further, since the light-weight coil is disposed on the movable lens frame 3, the weight of the lens frame 3 can be made light, and the lens frame 3 can be driven with a small current. Further, in the present embodiment, it is not necessary to surround the lens sheet 2a for holding the lens sheet 2a. Since the voice coil motor members (coils, yokes, magnets, and the like) are disposed in the manner of 卩3 1, 32, the size of the periphery of the lens sheets 2a and 2b can be reduced. The lens frame 3 of the movable portion is miniaturized and lightened, and the momentum at the time of photographing is the difference in the driving current (see Patent Document 丨, and the friction between the shaft 4 and the guide hole 35 is also reduced. Therefore, the lens sheets 2a and 2b can be driven with a small electric power. In the present embodiment, the guide shaft 4 is used as one of the magnetic circuits P, so that, for example, the yoke 6 (ie, The guide shaft 4 is differently provided with a projection: the lens frame 3 can be further miniaturized as compared with the case where the lens frame 3 is formed with a hole for inserting the projection. Embodiment 2: 317266 1281052 Fig. 6 is the present invention Fig. 7 is a perspective view showing a portion of the lens sheet driving device 20 shown in Fig. 6. Fig. 6 is a perspective view showing a first embodiment. The constituent elements described in Fig. 5 are assigned the same paying number to the same constituent element. The feature of this type of structure is that the current is supplied to the coil 12 of the coil 12. The vertical conductor 12 is, for example, a plate-like member. , having: along the side of the coil 5 (with the lens sheets 2a, 2b side The side of the opposite side) and the side portion 12d of the support portion 33 extending downward from the lower side 1d' is bent from the lower end of the side portion i2d toward the lower side of the lens frame 3 (more toward the inside than the ring ^) 12c; and the A-force in the bent portion, and the folded-back portion 1 in which the A is substantially V-shaped.

F F; The 邛12c and the folded-back portion 12b are formed by the bottom portion 63 of the pet ash yoke 6 and the support portion 33, and the bent portion 12c is long, and the hole portion of the 工12b into the ▲丨脰1 is protruded again. , the combination of the two sides of the branch, such as the branch of the branch, and the lower part of the system, are bent downwards, and are connected to the circuit base by means of the square block of the tin-buckle 2" 2b-cut end, or the connector, etc. 16 5.. In the configuration example shown in the diagram of the terminal block, in the figure 7, the 2b is set on the lower side of the lens frame 3, and the t δ is on the upper side of the lens frame 3, 317266 14 1281052. The wire 12 is not necessarily in the middle. μ 4 ] The member of the image device (that is, the biliary is preferably fixed to the camera portion, such as a movable member such as the non-lens frame 3), and the lens plate driving device according to the present embodiment has elasticity. The v-angle of the v-shape between the ΓΓ and the folded-back portion 1213 can accommodate the movement of the lenticular frame 3. Thereby, the conduction between the j-valley and the afternoon lens frame 3 circuit board 92 is achieved. (4) At the same time, it can be ensured that the coils 5 and (by) the bent portions A and (3) of the wires 12 are used to follow the movement of the lens frames, so that there is no smuggling of the lens frames 3 - r pairs In other words, the amount of the wire L is applied to the lens frame 3 by the guide wire 12. Since the wire 12 is connected to the circuit portion and fixed to the casing 11, the conductor 12 can be prevented from inadvertently moving when the earth plate 92 is guided. In the case of the A, the wire 15 of the coil 5 is wound around the frame to guide the coffin 15 and the wire 12 is fixed by soldering or the like, and the coil 5 can be lifted: as a part Assembled (partially assembled), the assembly side of the 'side' 2d extends along the side of the coil 5 in the Z direction, and the bend 1 and the folded portion (3) are located on the upper side or the lower side of the lens frame 3, so = The increase in the size of the Y-direction or the X-direction of the lens sheet driving device 1 and the P can make it difficult to accommodate the small-sized and lightweight light-receiving device 1G (see the patent document). Furthermore, the Q-wire 12 front end portion 2a, from the folded-back portion 2b to the circuit 317266 1281052 = 92 side: curved 'so, the wire i2 can be directly soldered to the circuit to reduce the number of components of the wiring member. As a result, The five-way substrate 92 H2 of the frame plate 92 is widened or the like, and the fixing strength of the circuit board 92 is read. The configuration is such that the wire 12 is formed into a plate shape, but is not limited to the plate. In order to prevent the wire 12 from being short-circuited with the yoke 6 or the like, the wire is coated with insulation ((10) (4), or (4) 6 and the surface of the magnetic sheet 8 may be provided with an insulating sheet. In the example shown in Fig. 7, the bent portion 〖2c and the folded portion 〖2] 3 are ΠV-shaped in the γζ plane, but are not limited. In this configuration, as long as the wire-to-night portion is bent on the upper side or the lower side of the lens frame toward the inner side of the coil 5. As shown in Fig. 8, the bent portion 12c and the folded portion (3) are at ^ XY In the plane in which the plane is slightly inclined, a U-shape may be formed. At this time, the bent portion 12c and the folded portion 12b are not separated from each other only in the X direction, and the arrow gentleman is not in the Z direction as shown in the figure. The lens frame 3 is moved in the z direction, and the angle in the γζ plane of the curved portion between the folded corner 卩12c and the folded portion 12b is elastically deformed, whereby the movement of the lens frame 3 can be followed.

At the front end of the 拙^17b, a ν-like shape is formed in the γ-ζ surface. Folding ', the department is called the fold... b is long and the second is: the upper side is folded back. The folding portion is fixed to the terminal portion (external terminal) of the circuit board 92 by a connecting portion (not shown) before the reference plate t2 7a.折 The bent portion 17b and the folded portion 17a are between the V-shaped 17 17 Λ 邛 邛 b b b b b b b b b b b b , 。 。 llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc llc In this state, the V green color between the upper faces of the wires 2/frame 3 is elastically deformed by the bent portion 17b and the folded-back portion, and is elastically deformed by the expansion of the u-bow. The bullet will be pressed in the direction of the -Ζ. When the coil 5 does not have a current flowing, the lens sheet Π 3] 7266 1281052 j 3 is located in the -Z direction due to the deletion of the wire 7 (i.e., the stop in the _z direction). When a current flows through the coil 5, as described in the embodiment, the electromagnetic force in the +2 direction is generated by the current of the coil 5 and the magnetic field of the magnet 7. The object image is imaged on the solid-state imaging element 91 at a position where the 疋 lens frame 3 is moved in the +Z direction to the position where the elasticity of the XY of the electromagnetic force disk η in the +z direction is balanced. When the stop current flows through the coil = time, the lens frame 3 returns to the movement limit of the Ζ direction due to the elastic force in the direction of the wire 17. As described above, the lens sheet driving device 30' according to the present embodiment generates the elastic pressure of the lens frame 3 by the elasticity of the wire so that the magnetic sheet 8 is not required (Fig. 2, etc.).

In the fourth embodiment, the relative position of the lens sheets 2a and 2b with respect to the solid-state imaging element 91 is adjusted by adjusting the position of the magnet 7 in the Z direction. The lens sheet driving device 1 (the Jth to 5th drawings) in the upper 逑 施 1 form sets the movable range of the lens frame 3, and the magnetic piece 8 is often more magnetic and \ direction center closer to the +Z side. The location. However, the embossed sheet driving mechanism of the present embodiment sets the movable range of the lens frame so that the magnetic sheet 8 can be located on the +z side of the center of the magnet 7 in the Z direction or at a position on the z side. 317266 1281052 The magnetic sheet 8 is elastically pressed toward the center of the magnet 7 having the highest magnetic flux density in the Z direction. Therefore, the state of the center (stable position) c in the Z direction is most stable. That is, when the current is not flowing through the coil 5, the lens frame 3 is stationary when the magnetic sheet 8 is at the stable position C. When the magnetic piece 8 is moved from the stable position + to the +Z direction, the magnetic piece δ is subjected to the elastic pressure from the magnet toward the Ζ direction depending on the amount of movement. Further, when the magnetic sheet 8 is moved from the stable position c to the j direction, the magnetic sheet 8 is subjected to the elastic pressure from the magnet 7 in the +^ direction depending on the amount of movement. Therefore, by adjusting the position (4) of the magnet 7 in the ζ direction to change the stable position C, the movement of the lens frame 3 can be moved in the '+' direction or in the - Ζ direction. The plate is adjusted only in the z-direction of the lens sheet driving device 4, for example, by adjusting the focal planes of the lens sheets 2a and 2b with respect to the solid-state imaging device imaging surface. By this adjustment, even if there is a manufacturing error in the U 2a, 2b or solid-state imaging element 91, the focal plane of the lens sheet 2" and the imaging surface of the solid-state imaging element 91 are confirmed. Moreover, even with the solid-state imaging element When the small depth is shallow, it is still compatible. 7 h Specifically, in the image sensor manufacturing process, 7, the magnetic attraction force is fixed (temporarily solidified to the magnetic light iron 62. In this state, the lens sheet is measured.

The surface of the 10,000, the soil 4 61, 62 is coated, or injected into the magnet 7 and the wall portion 61, Also between the 62. The mouthpiece> is mainly incorporated into the magnet 7 and the wall portion 6丨, & protection, forming a groove for injecting the adhesive The soils 61 and 62 are as described above. According to the fourth embodiment, by adjusting the Z direction of the magnet 7, the lens sheets 2a and 2b can be adjusted with respect to the position of the (4) imaging element (focus adjustment), so that it is not necessary. The lens frame 40 is further miniaturized, and the lens sheet driving device can be prepared separately, but the above-described adjusting device 18 can be equipped as standard in the imaging device. In the case of the four lens sheets m, the number of the transparent lenses is not limited to two, and it is also possible to use three or more lenses. In this case, the coils 5 are arranged adjacent to each other to hold the lens sheets. The portion of the lens sheet other than the g-gauge of 3 can obtain the effect of miniaturization of the above-described lens sheet driving device. Both sides of the direction are provided even in the above-described modes 1 to 4 of the coil 5, and between the coils 5 The number of magnets 7 is not limited to two, and only one of them may be provided on one side.
