Field of the Invention The present invention relates to a lens frame mounting structure, and is particularly suitable for mounting the lens frame while positioning the lens holder in the axial direction so as to obtain a prescribed focus position. The present invention relates to a mounting structure for a lens frame.

整する場合もある。In this case, a male screw portion is formed on the mounting side of the lens frame, and a holding hole having a female screw portion corresponding to this male screw portion is provided in the lens holder. The lens frame is screwed into a holding hole formed in the lens holder, and the amount of screwing adjusts the lens frame so as to match the focus with the detection surface of the CCD. Further, the eccentric pin fitted in the lens holder may be engaged with the lens frame, and the insertion depth of the lens frame may be adjusted by rotating the eccentric pin.

The lens frame is fixed to the lens holder by screwing a screw into a fixing hole penetrating from the outer periphery of the lens holder into the holding hole and pressing the surface of the lens frame with the tip of the screw. As a method of fixing the lens frame, there is a method of elastically holding the lens frame with a wavy spring in addition to the method of fixing with the screw.

ネが高価であることから、製造コストが増大する。However, in the above-described conventional lens frame mounting structure, when screwing screws to fix the lens frame with screws, the male screw of the lens frame and the lens holder are not used. Since there is play for meshing with the female screw, and when using an eccentric pin, there is play for fitting between the cylindrical portion of the lens frame and the holding hole of the lens holder. There is a problem in that the position or orientation of the frame changes and the focus position goes wrong. In addition, since the tip of the screw presses and fixes it, the posture of the lens frame may change due to vibration or impact even after the lens frame is once attached.
Care must be taken in handling after adjustment and mounting. On the other hand, when the wavy spring is used, the number of parts is increased and the wavy spring is expensive, so that the manufacturing cost is increased.

However, it is difficult to maintain the quality of the product because variations such as inclination of the axis occur.

は非常に困難である。Further, when the lens frame is mounted on the lens holder, it is desirable that a predetermined torque be required when adjusting the introduction depth of the lens frame in order to facilitate the adjustment work. In order to generate the predetermined screw tightening torque or the eccentric pin rotation torque, particularly high processing accuracy is required, and it is very difficult to obtain the optimum adjustment torque in reality.

The purpose is to realize a new lens frame mounting structure that can be used.

It is performed so that the focus of the zero lens group may be matched. At this time, a cutting resistance is generated when the ribs 23 are engraved with screws by self-tapping, and the male screw portion 13 and the ribs 23 are self-tapping and screwed together with almost no play. When the lens frame 10 is rotated, a required sliding resistance is inevitably received. The cutting resistance almost disappears after the rib 23 is once threaded, but the sliding resistance always occurs regardless of the position of the lens frame or the rotation direction.

手段を別途設けてもよい。When the lens frame 10 is screwed in, self-tapping is performed while applying a predetermined axial pressure to the lens frame 10, so that the male screw portion 13 and the female screw portion 22.
Even if there is a play between and, the screw thread of the male screw part 13 is fixed in a state of being pressed against the screw thread of the female screw part 22 from above. Therefore, sliding resistance between the male screw portion 13 and the female screw portion 22 is also generated, which results in further increasing the fixing force of the lens frame 10. If it is not necessary to adjust the position of the lens frame 10 again after adjusting the focus once, the lens frame 1
A fixing means such as pouring an adhesive may be separately provided in the threaded portion between the 0 and the holding hole 21.
