Each of the guiding portions abuts against the corresponding abutting portion 22 .
該等抵接部22與該等導引部之抵接關係，會使得該鏡筒座40以該透鏡組70之光軸Z為中心往復轉動時，產生沿該透鏡組70之光軸Z往復移動。說明如下：請參閱圖6，在一般位置時，該抵接部22與該第一平面411抵接，使該鏡筒座40位於一第一定焦位置P1。另外，請參閱圖7，當使用者撥轉該推桿44，使該抵接部22由該第一平面411通過該斜面413而抵接該第二平面412時，該鏡筒座40由該第一定焦位置P1沿該光軸移動至一第二定焦位置P2。藉由撥轉該推桿44，使該鏡筒座40於該第一定焦位置P1與該第二定焦位置P2之間往復移動，並同時帶動該鏡筒座40上之鏡筒30和透鏡組70沿該光軸Z移動，而達到切換鏡頭焦點之目的。The abutting relationship between the abutting portions 22 and the guiding portions causes the lens barrel holder 40 to reciprocate along the optical axis Z of the lens group 70 to reciprocate along the optical axis Z of the lens group 70. mobile. The description is as follows: Referring to FIG. 6 , in the normal position, the abutting portion 22 abuts the first plane 411 such that the barrel base 40 is located at a first fixed focus position P1 . In addition, referring to FIG. 7 , when the user dials the push rod 44 such that the abutting portion 22 abuts the second plane 412 through the inclined surface 413 by the first plane 411 , the lens barrel base 40 is The first fixed focus position P1 moves along the optical axis to a second fixed focus position P2. By rotating the push rod 44, the lens barrel holder 40 reciprocates between the first fixed focus position P1 and the second fixed focus position P2, and simultaneously drives the lens barrel 30 on the lens barrel holder 40 and The lens group 70 moves along the optical axis Z to achieve the purpose of switching the focus of the lens.
此外，在該鏡筒座40位於該第一定焦位置P1或第二定焦位置P2上時，該些定位凸部222位於該些定位凹部414中，並使該些凸塊221抵接於該第一平面411或該第二平面412，藉以使該鏡筒座40可穩固地位於該第一定焦位置P1或該第二定焦位置P2上，而不會偏移或晃動。In addition, when the lens holder 40 is located at the first focus position P1 or the second focus position P2, the positioning protrusions 222 are located in the positioning recesses 414, and the bumps 221 are abutted. The first plane 411 or the second plane 412 is configured such that the lens barrel holder 40 can be stably located at the first focus position P1 or the second focus position P2 without being displaced or shaken.
綜合以上所述可得知，本發明之鏡頭模組1不僅構造簡單，且不需使用凸輪軌道即可達到切換焦點之目的。In summary, as described above, the lens module 1 of the present invention is not only simple in construction, but also can achieve the purpose of switching focus without using a cam track.
又，本發明之導引部數量並不限於四個，抵接部之數量也不限於四個，各為三個或兩個，或者更多或更少，都不脫離本發明之精神。另外，導引部與抵接部之所在位置並不限於上述實施例所記載者，其兩者所在位置互換，也是本發明之另一種實施形態而已。Further, the number of the guide portions of the present invention is not limited to four, and the number of the abutment portions is not limited to four, each of three or two, or more or less, without departing from the spirit of the invention. Further, the position of the guiding portion and the abutting portion is not limited to those described in the above embodiments, and the positions of the two are interchanged, which is another embodiment of the present invention.
以上所述僅為本發明較佳可行實施例而已，舉凡應用本發明說明書及申請專利範圍所為之等效結構及製作方法變化，理應包含在本發明之專利範圍內。The above description is only for the preferred embodiments of the present invention, and the equivalent structures and manufacturing methods of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
