OPTICAL MODULE FOR PHOTOGRAPHING DEVICE AND PHOTOGRAPHING DEVICE COMPRISING THE SAME

摘要

An optical module for a photographing device is provided to simplify processing and assembling processes for manufacture and efficiently utilize a space, thereby implementing the thin type photographing device. A fixed lens group member(150) is arranged along a first optical axis direction facing a subject. A reflection member(160) discharges image light in a second optical axis direction vertical to the first optical axis direction. A first lens group member(110) comprises a first lens group arranged along the second optical axis direction, and a first girth unit(112) having a first guide protrusion(112b) in one side as supporting the first lens group. A second lens group member(120) comprises a second lens group spaced from the first lens group along the second optical axis direction, and a second girth unit(122) having a second guide protrusion(122b) in one side as supporting the second lens group. A zoom motor(130) provides power for changing a distance between the first and second lens group members. A plane cam member(140) comprises the followings. A gear unit(141) is formed in a part of a girth in order to receive the power form the zoom motor. First and second cam grooves(142,143) are formed so as for the first and second guide protrusions to be inserted to move the first and second lens group members.
