  As shown in FIG. 1, when the lens barrel 11 is inserted into the storage portion 26, the front end surface of the holder 21 is at a lower position (Z2 side) than the front end surface 11 b of the lens barrel 11. The front end surface of the second abutting portion 27 shown in FIG. 2 is the first abutting surface of the first abutting portion 15 when the lens barrel 11 is inserted into the storage portion 26 as shown in FIG. A second abutting surface 27a that abuts against 15a is configured. In this embodiment, the second abutting surface 27a is formed as a surface parallel to a horizontal plane (XY plane).

  As shown in FIG. 2, the holder 21 is formed with a plurality of concave portions 28 that are bottomed and penetrate forward (Z1) at intervals of 90 degrees on the inner peripheral surface 26a.

The yoke 23 shown in FIG. 2 is formed in a substantially ring shape, and an internal space is provided in the yoke 23. Magnets (not shown) are held in the internal spaces of four holding portions 23 a provided at equal intervals around the yoke 23. The holder 21 is disposed in the through hole 23b located at the center of the yoke 23. The coil portion 22 fixedly supported by the holder 21 is disposed in the inner space of the yoke 23, and the holding portion 23a And the coil portion 22 are in a mutually facing positional relationship.

The support 16 shown in FIG. 2 has a voice coil motor (VCM) structure.
The magnets have different polarities on the side facing the coil part 22 and the side fixed to the yoke 23. When the coil portion 22 is energized, a driving force (electromagnetic force) is generated in the Z direction based on the Fleming left-hand rule, and the holder 21 can be moved in the Z direction. The support 16 shown in FIG. The structure can be realized.

  Next, an assembly method for assembling the lens barrel 11 in the present embodiment to the support 16 will be described.

  First, the lens barrel 11 shown in FIG. 3 is inserted straight into the storage portion 26 formed in the holder 21 incorporated in the support 16 without rotating. As described above, the outer peripheral surface 11a of the lens barrel 11 and the inner peripheral surface 26a of the storage portion 26 are both cylindrical surfaces, and the inner peripheral surface 26a constitutes a guide surface for the outer peripheral surface 11a. Therefore, the outer peripheral surface 11a of the lens barrel 11 can be slid along the inner peripheral surface 26a of the storage portion 26 and inserted straight in the rear end direction (Z2).

  FIG. 1 shows a state in which the lens barrel 11 is inserted into the storage portion 26 of the support 16. As shown in FIG. 3, a plurality of first abutting portions 15 are formed on the outer peripheral portion on the front end side of the lens barrel 11, while a plurality of second abutting portions 27 are formed on the front end portion 21 a of the holder 21. ing. When the lens barrel 11 is inserted into the storage portion 26 of the support 16, the first abutting surface 15 a formed by the inclined surface of the first abutting portion 15 and the front end surface of the second abutting portion 27. The second butting surface 27a is abutted. When the first butting portion 15 and the second butting portion 27 come into contact with each other, the lens barrel 11 cannot be further linearly inserted in the rear end direction (Z2) without rotating. Subsequently, a minute height adjustment (focus adjustment) of the lens barrel 11 is performed.

  As shown in FIG. 1, the lens barrel 11 is accommodated in the accommodating portion 26, and then before the height adjustment (focus adjustment) of the lens barrel 11 is performed, the lens barrel 11 is inserted into the jig insertion hole 14 provided in the lens barrel 11. Can be filled with an uncured thermosetting resin 30. The thermosetting resin 30 may be applied before the lens barrel 11 shown in FIG. 3 is inserted into the storage portion 26 of the support 16.

  A jig 31 shown in FIG. 1 is provided with a handle portion 32 formed in a ring shape and four arm portions 33 extending from the handle portion 32 toward the inner side. Each arm portion 33 is formed at intervals of 90 degrees along the periphery of the handle portion 32, similarly to the jig insertion hole 14. The tip of each arm portion 33 is bent to form a protruding portion 33a extending downward (Z2), and each protruding portion 33a has an outer shape substantially the same shape as the jig insertion hole.

  As shown in FIG. 4, each protrusion 33 a is inserted into each jig insertion hole 14. Then, the handle portion 32 of the jig 31 is rotated in the counterclockwise direction CCW, for example.

  As shown in FIG. 5A, when the lens barrel 11 is rotated counterclockwise CCW using the jig 31 (the jig 31 is omitted in the partially enlarged perspective view of FIG. 5), the lens barrel 11 slides on the inner peripheral surface 26a of the storage portion 26, which is a guide surface, and the lens barrel 11 can be appropriately rotated.

  As shown in FIG. 5A, the first abutting portion in which the second abutting surface 27 a of a part of the second abutting portion 27 formed in the front end portion 21 a of the holder 21 is formed in the lens barrel 11. 15 abuts against the first abutting surface 15a. When the lens barrel 11 is rotated counterclockwise CCW using the jig 31 from this state, as shown in FIG. 5B, the second abutting surface 27a of the second abutting portion 27 is first abutted. The first abutting surface 15a formed by the inclined surface of the portion 15 is relatively moved. For this reason, the lens barrel 11 can be pushed up in the height direction from the state of FIG. 5A, and minute height adjustment (focus adjustment) can be performed between the first butting portion 15 and the second butting portion 27. This can be performed by using the height adjustment mechanism unit 34 that uses the constructed cam mechanism.

  In this embodiment, as shown in FIG. 5B, after the height adjustment (focus adjustment) of the lens barrel 11 is completed, the thermosetting resin 30 is cured without removing the jig 31 from the jig insertion hole 14. Then, after fixing the outer peripheral surface 11a of the lens barrel 11 to the inner peripheral surface 26a of the holder 21, the jig 31 can be removed.

  Alternatively, as a fixing method between the lens barrel 11 and the holder 21, the jig 31 is used when the height adjustment (focus adjustment) shown in FIG. 5B is completed without filling a bonding material such as the thermosetting resin 30 in advance. May be removed from the jig insertion hole 14 and the jig insertion hole 14 may be filled with a bonding material and fixed. Alternatively, before the jig 31 is removed from the jig insertion hole 14 after the height adjustment (focus adjustment) shown in FIG. A bonding material is injected from a recess 28 provided in the inner periphery of the holder 21 or a gap between the lens barrel 11 and the holder 21, and the outer peripheral surface 11a of the lens barrel 11 and the inner peripheral surface 26a of the holder 21 are fixed. More preferably, after the jig 31 is removed from the jig insertion hole 14, the jig insertion hole 14 is further filled with a bonding material and fixed.

  In this embodiment, even if the jig insertion hole 14 is formed to penetrate from the front end side (Z1) to the rear end side (Z2), height adjustment (focus adjustment) can be appropriately and easily performed using the jig 31. And a camera module that does not require a screw structure. Further, since the jig insertion hole 14 is provided in the outer peripheral surface 11a of the lens barrel 11, the internal space 12 of the lens barrel 11 can be widened.

  However, it is preferable that the jig insertion hole 14 is formed of a bottomed recess, that is, not formed so as to penetrate from the front end side (Z1) to the rear end side (Z2).

  As shown in the partially enlarged longitudinal sectional view shown in FIG. 6, in this embodiment, the jig insertion hole 14 is formed on the outer peripheral surface 11a of the lens barrel 11 in the direction from the front end surface 11b of the lens barrel 11 to the rear end portion (Z2). ) Is formed up to the middle. As described above, since the jig insertion hole 14 is provided at the position of the outer peripheral surface 11a and the jig insertion hole 14 is formed only halfway, as shown in FIG. In particular, it can be formed easily and appropriately so as to be widest at the rear end portion 12a side where the jig insertion hole 14 is not formed. As shown in FIG. 6, the rear end portion 12 a of the inner space 12 of the lens barrel 11 can hold a lens having a lens diameter T <b> 3. A suitable lens unit that can be disposed at the end and has excellent image quality can be configured. In FIG. 6, the inner space 12 of the lens barrel 11 is the narrowest on the front end portion 12b side, and is wide at the intermediate portion 12c between the front end portion 12b and the rear end portion 12a, and a plurality of lenses having different lens diameters. Can be held.

  Furthermore, the jig insertion hole 14 is formed with a bottomed recess, that is, not formed so as to penetrate from the front end side (Z1) to the rear end side (Z2). Even if it is used as a hole, there is no problem that the bonding material flows out toward the rear (Z2) of the holder 21, and the space between the outer peripheral surface 11a of the lens barrel 11 and the inner peripheral surface 26a of the holder 21 is simple and reliable. It can be fixed to.

  7 is a perspective view of the lens barrel of the second embodiment, FIG. 8 is a partially enlarged perspective view of a holder incorporated in the support, FIG. 9 is an enlarged perspective view of a second abutting portion formed on the holder, and FIG. The partial perspective view of the camera module which shows the state which inserted the lens-barrel in the accommodating part of the holder is shown.

  7 differs from the lens barrel 11 of FIG. 3 in the shape of the first abutting portion 41. That is, in FIG. 3, the first abutting surface 15 a of the first abutting portion 15 is formed as an inclined surface, but the first abutting surface 41 a of the first abutting portion 41 shown in FIG. 7 is a horizontal plane (X− Y) A plane parallel to the direction.

  The holder 42 shown in FIGS. 8 and 9 has a ring shape like the holder 21 shown in FIG. 2, and a storage portion 46 is formed at the center. A second abutting portion 43 is formed on the upper end portion 42a of the holder 42. The second abutting surface 43a located on the front end surface of the second abutting portion 43 is an inclined surface unlike FIG. It is formed with. The second abutting surface 43a formed by the inclined surface is formed in a straight line when viewed from the side.

  Then, as shown in FIG. 10, the lens barrel 40 is straightly inserted into the storage portion 46 of the holder 42 without being rotated, and the first butting surface 41 a of the first butting portion 41 and the second butting portion 43 are inserted. 2 With the abutting surface 43a in contact, the jig 31 shown in FIG. 1 is inserted into the jig insertion hole 45 of FIG. 10 and rotated in the clockwise direction CW or counterclockwise CCW, as in FIG. Let At this time, when the jig is rotated while being pressed in the rear end direction (Z2), the first butting surface 41a of the first butting portion 41 of the lens barrel 40 is a second butting formed by an inclined surface. By moving on the second abutting surface 43a of the portion 43, minute height adjustment (focus adjustment) of the lens barrel 40 can be performed with high accuracy.

  The fixing method between the holder and the lens barrel is the same as described above, and as shown in FIG. 10, the bonding material 47 is filled into the jig insertion hole 45 of the bottomed recess (bag path shape). Thus, the lens barrel 40 and the holder 42 can be fixed easily and reliably.

  Further, since the jig insertion hole 45 is formed from the front end surface of the lens barrel 40 to the middle of the rear end direction (Z2), the inner space of the lens barrel 40 can be formed most widely on the rear end side, and the lens diameter is increased. A large lens can be effectively installed at the rear end of the internal space.

  Although the camera module in the above has an autofocus structure, it can also be applied to a manual focus structure that does not have autofocus (a drive unit is not provided on the support).

  However, by applying this embodiment to the autofocus structure, it can be easily and reliably fixed between the holder and the holder that moves with the lens barrel, and in this case, the bonding material flows out of the area other than between the holder and the lens barrel. The autofocus structure can be formed easily and stably. Moreover, the second abutting portion can be provided at the upper end portion of the holder, and the height adjusting mechanism portion and the fixing structure can be appropriately formed between the lens barrel and the holder.

  Further, in this embodiment, the outer peripheral surface of the lens barrel and the inner peripheral surface of the storage portion of the support body are not provided with a screw structure formed with a cylindrical surface, but are limited to a configuration in which both are formed with a cylindrical surface. The outer peripheral surface of the lens barrel and the inner peripheral surface of the storage portion are formed in a shape that can be inserted straight into the storage portion without rotating the lens barrel and that the lens barrel can be rotated in the storage portion. It only has to be. However, it is preferable that the outer peripheral surface of the lens barrel and the inner peripheral surface of the storage portion of the support body are both formed of a cylindrical surface so that the lens barrel can be stored smoothly and stably in the storage portion of the support body.

  In the present embodiment, both the first abutting surface and the second abutting surface may be inclined surfaces, or the inclined surfaces may be curved rather than linear. Further, the inclined surface may be formed in a stepwise manner such as a slope-horizontal plane-slope. Or it is good also as a structure which changes the angle of an inclined surface on the way.
