The high-quality and miniaturized dual-required mode = optical imaging module used in the device or portable type, the large-sized eight has a common photosensor type, one is CCD (aiarge-CcmPled Device; charge) The coupling element), the other is CM〇S (C〇mplementary Metal-〇xide Semiconductor; complementary oxidized metal semiconductor). According to the optical photography module, there is a shutter device for solving the problem in the process of image exposure, and the operation principle is substantially as follows: having an optical path disposed in front of a CCD or a CMOS to perform an opening/closing operation. The two shutter blades, and the use of a solenoid valve (or electromagnetic actuator) to control the movement of the shutter blade to open or close. When the electromagnetic valve is energized in the standby state of the photographic framing, electromagnetic force is generated to control the shutter blade to open/close, so as to control the light sensor to receive light or not to be light, thereby achieving exposure control; for example: Chinese mainland patent disclosure No. CN1503046A reveals the shutter device of this principle. 200935167 However, in today's consumer market, the pursuit of thin and short, the space for the installation of internal components of handheld mobile devices or tape-type computer devices has become narrower, and the optical photography modules have to be miniaturized. The requirement 'to make the overall size of the shutter device must also meet the requirements of miniaturization and thinning.' Therefore, how to design a shutter device that can reach the micro and thin shape and meet the requirements of the manufacturer's standard when it is actuated The goals and issues pursued by relevant researchers and manufacturers.
