Abstract

본 발명의 목적은 부품수를 증가시키지 않고 요동을 발생시키지 않으면서 캠 환의 광축 방향으로의 이동제한을 행할 수 있도록 하는 것입니다.An object of the present invention is to enable the cam ring to be restricted in the optical axis direction without increasing the number of parts and without causing fluctuations.

본 발명은 접안틀(1)에 밖에서 삽입되는 캡 환(2)에 그 내측 방향으로 돌출하는 이동제한 돌기 (2c)를 형성한 다. 접안틀(1)의 외주측에 이동제한 돌기(2c)가 체결하는 광축 주위의 환상 홈(1c)를 형성함과 아울러 캠 환(2)을 광축 방향으로 이동시키면 이동 제한 돌기(2c)가 환상 홈(1c)으로부터 벗겨지는 노치(1e)를 환상흠(1c)의 일부를 형성한다.The present invention forms a movement limiting projection (2c) protruding in the inward direction on the cap ring (2) inserted into the eyepiece (1) outside. When the cam ring 2 is moved in the optical axis direction, the annular groove 1c around the optical axis to which the movement limiting projection 2c is fastened is formed on the outer circumferential side of the eyepiece 1, and the movement limiting projection 2c is annular. The notch 1e peeled off from the groove 1c forms a part of the annular flaw 1c.

Claims

The lens frame housing the eyepiece is fixedly mounted in the eyepiece frame fixedly mounted to the main body so as to be movable in the optical axis direction, and a cam ring in which a spiral cam groove is formed is rotatably inserted into the outer periphery of the eyepiece frame. In the binocular correction mechanism of the binocular for adjusting the lens ring in the optical axis direction by providing a projection connected to the groove on the lens frame and rotating the cam ring, the movement limiting projection projecting in the inner direction of the cam ring is projected. And an annular groove around the optical axis to which the movement limiting projection is fastened to the outer circumferential side of the eyepiece frame, and moving the cam ring in the optical axis direction to remove the notch from the annular groove. A binocular attempt correction mechanism characterized in that formed on a part of the annular groove.

2. The binocular attempt correction according to claim 1, wherein a movement limiting portion is formed on an outer circumferential side of the eyepiece frame to contact one end face of the cam ring and to limit the movement of the cam ring in one direction of the optical axis direction. Instrument.

At least one of the eyepiece frame for storing the eyepiece and the objective lens for storing the objective lens are installed so as to be movable in the optical axis direction, and the cam-exchanged temperature in which the spiral cam groove is formed. Rotatably attached to the main body side member, and a projection for fastening to the cam groove is mounted on one lens frame, and the lens ring is moved in the direction of the axis of axial rotation while rotating the cam ring. An optical device for changing a distance between a lens and a relative, comprising: forming a movement limiting projection projecting radially on the cam ring, and forming an annular groove around the optical axis to which the movement limiting projection is fastened on the main body side member; Further, when the cam ring is moved in the optical axis direction, the notch in which the movement limiting projection is peeled off from the annular groove is the annular groove. Optical equipment characterized in that the part of the.

A conventional lens frame having an eyepiece housed therein and having a cambis protruding from the outer surface in a direction substantially perpendicular to the optical axis of the eyepiece, and an outer surface of the lens frame arranged to surround the outside of the lens frame One end that can be fixedly fixed to the inner surface and the barrel body in sliding contact with the inner surface, a circumferential annular groove provided on the outer surface of the outer surface and the other end, and a long hole extending in parallel with the optical axis outside the eyepiece of the lens frame. Has. A conventional eyepiece that permits relative movement of the lens frame in the optical axis direction because the cam vis of the lens frame penetrates the long hole, but inhibits relative rotation around the optical axis of the lens frame; An inner surface that is disposed to surround the outside of the eyepiece and is in sliding contact with an outer surface of the eyepiece, a movement limiting protrusion that projects radially inward from the inner surface and extends into the annular groove of the eyepiece, and typically has a spherical cam groove And the movement limiting projection is engaged with the annular groove of the eyepiece so as to suppress relative movement of the cam ring in the optical axis direction, allowing relative rotation around the optical axis of the cam ring and the cam groove in the cam groove. Since the vis is interposed, the lens frame is moved relatively in the optical axis direction in accordance with the rotation of the cam ring. The attempt correction mechanism, characterized in that consisting of a normal cam ring.

5. The eyepiece according to claim 4, wherein the eyepiece has a notch extending from the annular groove to the end face of the other end and opening in the end face, and when the cam ring is fitted to the eyepiece, the ring of the cam ring is An attempt correction mechanism characterized in that the cam ring is allowed to move relative to the eyepiece in the direction of the optical axis, and the movement limiting projection can be inserted into the annular groove by matching the movement limiting projection with the notch. .

The said outer surface of the said eyepiece frame is provided with the movement limit part of Claim 4 or 5 which contact | connects one end surface of the said cam ring, and restricts the movement of the cam ring in one direction of the said optical axis direction. Attempt correction mechanism.
