1. Field of the Invention
The present invention relates to a driving mechanism for moving an object.
2. Description of the Background Art
In recent years, a small electronic device (for example, a cellular phone) to which an image capturing function is added by mounting a micro camera unit (MCU) is being spread rapidly. With the spread, a driving apparatus used for an AF mechanism or a zoom mechanism for the MCU is being downsized.
There is a driving apparatus using MEMS (Micro Electro Mechanical Systems) manufactured by the semiconductor microfabrication technique to realize downsizing. For example, in Katsuo Kurabayashi “MEMS application (4) Formation of “polymer MEMS” on Si and application to biotechnology and optical technology by utilizing flexibility and transparency”, NIKKEI MICRODEVICES, May 2005, No. 239, pp. 71-76, a driving apparatus for driving a member-to-be-driven (a lens in this case) made of PDMS (polydimethylsiloxane) in a perpendicular direction as an application example of polymer resin (polymer) MEMS is proposed.
The number of parts constructing such a driving apparatus is about 20, and the number of parts connecting those parts is also about 20. As the driving apparatus is becoming smaller, it becomes difficult to connect the parts with high precision, and there is a problem such that an assembly error occurs.
