Abstract

PURPOSE: A switching device is provided to switch optical filters having different characteristics. CONSTITUTION: A filter 1(2) and a filter 2(3) are stuck to a filter sticking device(1). The filters are connected with a moving shaft(4) of a gear 2(7). In rotating the motor forward, the filter 1 is located between a lens and a photographing element. Otherwise, the filter 2 is located between the lens and the photographing element when the motor is rotated backward.

Description

모터(moter)를 이용한 광학 Filter 절환 장치{OPTICAL FILTER SWITCHING DEVICE USING MOTORS}Optical filter switching device using a motor {OPTICAL FILTER SWITCHING DEVICE USING MOTORS}

본 발명은 전자식 촬상 소자가 있는 카메라에 사용하는 광학식 필터의 절환에 관한 것으로, 더욱 상세하게는 전자식 촬상소자가 있는 Camera에 두 종류 이상의 필터를 사용하기 위해 모터를 이용한 필터의 교환 방식에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the switching of an optical filter for use in a camera with an electronic imaging device, and more particularly to a method of replacing a filter using a motor to use two or more types of filters in a camera with an electronic imaging device.

기존의 전자식 촬상소자가 있는 Camera는 1개의 필터만을 사용하기 때문에 별도의 필터의 절환 장치가 필요하지 않았다.Conventional cameras with electronic imaging devices use only one filter, so no separate filter switching device is required.

본 발명은 전술한 카메라에 필요에 따라 다른 특성을 갖는 필터를 2개 사용 할 경우 이를 절환하는 장치를 제공하는데 본 발명의 목적이 있는 것이다.The present invention has an object of the present invention to provide an apparatus for switching between two filters having different characteristics as necessary for the camera described above.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

그림 1은 본 기술고안에 따른 절환방식을 설명하기 위한 그림이다.Figure 1 is a diagram to explain the switching method according to this technical design.

필터 부착장치(1)에 필터1(2)와 필터2(3)가 부착되어 있으며 이는 기어 2(7)의 이동하는 이동축(4)과 연결 되어있다Filter 1 (2) and Filter 2 (3) are attached to the filter attachment device (1), which is connected to the moving shaft (4) of the gear 2 (7)

모터가 정회전을 하게 되면 필터1(2)가 렌즈와 촬상 소자의 사이에 위치하게 된다.When the motor rotates forward, the filter 1 (2) is positioned between the lens and the imaging device.

반대로 모터가 역회전을 하게 되면 상기와는 반대로 필터2(3)이 렌즈와 촬상소자 사이에 위치하게 된다On the contrary, if the motor rotates in reverse, the filter 2 (3) is located between the lens and the image pickup device.
