Title:
MICRO LENS MODULE
Document Type and Number:
Japanese Patent JP2005250432
Kind Code:
A
Abstract:
To provide a micro lens module in which a zoom function and an automatic focus adjustment function are ensured even with a small lens module by employing a lens moving structure using a piezoelectric drive means.
The lens section is located in a case and includes at least one lens. The moving member is rotatably connected to the inside of the case, and also connected to the lens section so that the lens section is moved forward and backward. The drive means is mounted in the case such that a driving force for moving the lens section is transmitted to the moving member by repeating the contact or noncontact status of the drive means with the moving member and the separation of the drive means from the moving member.
