Abstract
Provided is a camera module capable of stably holding a holder and preventing center displacement of a lens. In the camera module, a first thread part 3 is formed on either the holder 2 or a holding member 4 and a second thread part 6 is formed on the other, such that the flat faces of the tops of the upper edges 3a of the first thread part 3 are slidably disposed in contact with the corresponding flat faces of the bottoms of the lower edges 6b of the second thread part 6. This prevents movement of the holder 2 in a lateral direction (i.e., in the direction of arrow A2), and hence center displacement of the holder 2 from an imaging element 8. In addition, engaging of the flat faces of the upper ridges and lower ridges of the threads minimizes movement of the holder 2 in a vertical direction (i.e., in the direction of arrow A1) relative to the holder member 4. Accordingly, the holder 2 is stably held.
Description
Technical field
The present invention relates to a kind of mobile phone etc. of being suitable for and go up the camera model that is suitable for.
Background technology
If the accompanying drawing of the existing camera model of explanation, then Fig. 3 be existing camera model want portion's sectional view, Fig. 4 is the key diagram of the engagement of expression external screw thread of existing camera model and internal thread, next, the formation of existing camera model is described according to Fig. 3, Fig. 4, then keep the peripheral part of the clamp cylinder 52 of camera lens 51 in inside, be provided with external screw thread 53, this external screw thread 53 has the root 53b that the cross section forms the ridge 53a of trapezoidal shape and is positioned at the trapezoidal shape between ridge 53a.
The retaining member 54 that keeps anchor clamps 52, have cylindrical portion 55 and the internal thread 56 that is arranged in this cylindrical portion 55, this internal thread 56 has the root 56b that the cross section forms the ridge 56a of trapezoidal shape and is positioned at the trapezoidal shape between ridge 56a, simultaneously, be screwed into the external screw thread 53 of anchor clamps 52 in the internal thread 56 of this retaining member 54, anchor clamps 52 are installed on the retaining member 54.
And, as shown in Figure 4, for external screw thread 53 and internal thread 56 are screwed into easily, ridge 53a, the 56a of trapezoidal shape and root 53b, the 56b of trapezoidal shape have clearance ground mutually and form, between the napex of between the bottom of the top of ridge 53a and root 56b and the bottom of root 53b and ridge 56a, become the mutual empty standard width of a room in an old-style house every state.Thereby, when external screw thread 53 is screwed into internal thread 56, the lower side sliding contact of the upper side of ridge 53a and ridge 56a and being screwed into, but, when being screwed into end, because clearance and between the upper side of the lower side of ridge 53a and ridge 56a, produce gap S4, scope at this gap S4, anchor clamps 52 up and down (to rocking of arrow A 1 direction), and between the bottom owing to top that is formed on ridge 53a and root 56b, and between the top of the bottom of root 53b and ridge 56a the empty standard width of a room in an old-style house every the state of (gap S5), thereby, the scope of crack S5 betwixt, anchor clamps 52 move (to rocking of arrow A 2 directions) in the horizontal.And the circuit substrate 58 that imaging apparatus 57 has been installed is installed in retaining member 54 bottoms, forms existing camera model (for example, with reference to patent documentation 1)
Patent documentation 1: the spy opens 2003-32525 communique (the 2nd～3 page, Fig. 2, Fig. 4)
But, in existing camera model, the problem that exists is external screw thread 53 and internal thread 56, has the gap S4 of above-below direction and horizontal gap S5 and meshes, thereby, anchor clamps 52 are at above-below direction and transversely produce big rocking, not only can not keep anchor clamps stable, and, horizontal the rocking of anchor clamps 52, cause camera lens 51 misalignments, become a big defective with respect to imaging apparatus 57.
Summary of the invention
