In the second setting, if the magnetic body 2 4 is close to one of the first lines, it is the S pole ', and one end of the second coil portion 982 is the N 8 12 1278652 pole. When the current is passed, the first coil is turned on. The portion 981 and the second coil portion 982 generate a magnetic field effect of the S pole, and when the magnetic body 24 and the first coil portion 981 generate a repulsive force, both the magnetic body 24 and the second coil portion 982 generate The power of attraction. Alternatively, one end of the magnetic body 24 close to the first coil portion 981 is an N pole, and one end of the second coil portion 982 is an S pole, and when the current is supplied, the first coil portion 981 and the second coil portion 982 generate an N pole. The magnetic field effect, and the magnetic body 24 and the first coil portion 981 both generate a repulsive force, and both the magnetic body 24 and the second coil portion 982 generate a suction force. Thereby, the magnetic body 24 moves toward the second coil portion 982, and the magnetic body 24 is inserted into the opening 982a (not shown) of the second coil portion 982. Since the filter 22 is disposed on the sliding portion 983, and the sliding portion 983 is pivotally connected to the magnetic body 24, the sliding portion 983 slides along with the magnetic body 24, and the filter 22 is aligned and driven. Overlaps the window aperture 18 as shown in FIG. The filter 22 of the present invention is composed of more than one optical film, preferably an IR Cut Filter or an IR Filter, which is usually disposed on the photographic lens 72. The front end, the main function is to isolate stray light and block IR cut. For the photographic device 70 used for all-weather use, when the amount of light in the environment changes too much, it is usually necessary to adjust by the use of the filter 22. The material of the filter 22 can be selected differently as needed. When the environment is in a low resolution, the filter usually adopts an optical low pass filter (OLPF) and an infrared cut filter ( IR cut filter) and other two-layer combination. When the environment is in high resolution, the 8 13 1278652 filter usually adopts three layers of optical low-pass filter (OLPF), IR cut filter and optical low-pass filter (OLPF). The combination. In view of the above, the present invention has been described above in terms of a preferred embodiment, and is not intended to limit the invention, and various modifications may be made without departing from the spirit and scope of the invention. And the scope of the present invention is defined by the scope of the appended claims.
