본 고안은 틸트(TILT)방지용 경통결합구조에 관한 것으로 특히 캠코터의 주요 구성 부분인 줌유니트 경통의 결합시 생길 수 있는 틸트 현상을 없애기 위한 것이다.The present invention relates to a tilt coupling structure for preventing tilt (TILT), in particular to eliminate the tilt phenomenon that may occur when the zoom unit barrel, which is the main component of the cam coater.

종래 캠코더의 경통결합구조는 제 1 도 내지 제 3 도와 같이 전경통(11)과 후경통(12)을 결합 시키는 결합수단으로 안내홀(2)에 삽입되는 안내판(1)과, 제 1 나사홀(3)과 제 2 나사홀(4)에 연결 삽입되는 경통체결나사(5)로 구성되었다.The barrel coupling structure of the conventional camcorder is a guide plate 1 inserted into the guide hole 2 and a first screw hole as a coupling means for coupling the front barrel 11 and the rear barrel 12 as shown in FIGS. 1 to 3. (3) and a barrel fastening screw (5) inserted into the second screw hole (4).

도면중 미설명부호 6은 전경통(11)에 설치된 체결 기준면이고 7은 후경통(12)에 설치된 체결 기준면이다.In the figure, reference numeral 6 is a fastening reference plane installed in the foreground cylinder 11 and 7 is a fastening reference plane installed in the rear barrel 12.

이와 같이 구성된 캠코더는 제 1도와 같이 포커스 경통과 줌 경통이 이미 결합되어 있는 후경통(12)에 1군 렌즈가 결합된 전경통(11)을 결합시키기 위해 다수개의 체결나사(5)를 사용하여 결합시키게 되는데 이에 앞서 각각의 경통(11,12)에 렌즈의 광측을 맞추기 위해 설치된 안내핀(1)을 안내홀(2)에 제 3 도와 같이 끼우고 평면도로 관리되어 있는 체결 기준면(6,7)을 밀착시킨후 체결나사(5)로 경통을 결합시킬때 광학계 성능에 악영향을 미치는 요인의 하나인 틸트를 없애기 위해 독립된 경통을 결합시키는 수단인 다수개의 체결나사(5)의 체결력을 토크(Torque)로 관리하면서 경통을 결합시켰다. 그러나 체결 토크를 일정하게 관리하였다 하더라도 체결나사의 외경 및 체결구멍(3, 4)의 크기 편차에 의해 나사(5)가 결합되는 다수개의 체결 기준면이 한쪽으로 밀린다던지 하는 결점이 있어 요구하는 광학계 성능을 만족시키지 못하는 문제점이 있었다.The camcorder configured as described above uses a plurality of fastening screws 5 to couple the front barrel 11 coupled with the group 1 lens to the rear barrel 12 to which the focus barrel and the zoom barrel are already coupled, as shown in FIG. Prior to this, the guide pins (6, 7) inserted into the guide holes (2) together with the third guides (3, 7) are installed to align the optical side of the lens to the respective barrels (11, 12). ) And the fastening force of the plurality of fastening screws (5), which is a means for joining independent barrels to remove the tilt, which is one of the factors that adversely affect the optical system performance when the barrel is coupled with the fastening screw (5). Combined with the administration of the barrel. However, even if the tightening torque is constantly managed, there is a drawback that a plurality of fastening reference planes to which the screw 5 is coupled are pushed to one side due to the outer diameter of the fastening screw and the size deviation of the fastening holes 3 and 4. There was a problem that does not satisfy.

본 고안은 이러한 점을 감안하여 결합될 상대경통을 탄성력에 의한 일정한 힘으로 밀어주는 후경통의 안내보스가 체결되는 경사홈과, 안내보스를 밀어주는 탄성부재와, 상기 탄성부재의 이탈을 방지하는 이탈방지수단을 구비함으로서, 광학계 성능에 악영향을 주는 여러요인들의 하나인 틸트 현상을 방지하고 광학설계시 요구 되었던 광학성능을 만족시키는데 목적이 있다.The present invention in view of this point, the inclined groove to which the guide boss of the rear barrel to push the relative barrel to be coupled with a constant force by the elastic force, the elastic member for pushing the guide boss, and to prevent the separation of the elastic member By providing the separation prevention means, it is aimed to prevent the tilt phenomenon, which is one of several factors that adversely affect the performance of the optical system and to satisfy the optical performance required in the optical design.

본 고안을 제 4 도 내지 제 6 도에 의해 설명한다.The present invention will be described with reference to FIGS. 4 to 6.

경통체결 나사(107)에 의해 결합되는 캠코더의 결합구조에 있어서, 결합된 전경통(101)의 탄성력에 의해 일정한 힘으로 밀어주는 후경통(102)의 안내부스(104)가 체결되는 경사홈(103)과, 상기 안내보스(104)를 밀어주는 스프링(105)과, 상기 스프링(105)의 이탈을 방지하는 캡(106)을 구비하였다.In the coupling structure of the camcorder coupled by the barrel fastening screw 107, the inclined groove to which the guide booth 104 of the rear barrel 102 is pushed by a constant force by the elastic force of the combined foreground cylinder 101 ( 103, a spring 105 for pushing the guide boss 104, and a cap 106 for preventing the spring 105 from being separated.

그리고 다른 실시예로 안내보스(104)를 밀어주는 고무(205)를 구비하였다.In another embodiment, a rubber 205 for pushing the guide boss 104 is provided.

도면중 미설명부호 108, 109는 각각 경통의 체결기준면을 나타낸다.In the drawings, reference numerals 108 and 109 denote reference surfaces of the barrel, respectively.

이와 같이 구성되는 본 고안 캠코더는 복수개의 경통체결나사(107)에 의해 전경통(101)과 후경통(120)이 결합될때 기준면이 되는 복수개의 체결기준면(109)과 전경통(101)의 경사홈(103)에 체결되어 경통이 회전하지 못하도록 스피링(105)의 탄성에 의해 지지되는 안내보스(104)가 항상 일정한 힘으로 전경통(101)을 밀어주므로 체결나사의 외경 및 체결구멍의 크기편차에 관계없이 정확히 체결되어 있어 요구되는 광학계 성능을 만족시킬 수 있다.The present invention constituted as described above is inclined of the plurality of fastening reference planes 109 and the foreground cylinder 101 which are reference planes when the front barrel 101 and the rear barrel 120 are coupled by the plurality of barrel fastening screws 107. Since the guide boss 104, which is fastened to the groove 103 and supported by the elasticity of the spring ring 105, does not always rotate, pushes the foreground cylinder 101 with a constant force, the outer diameter of the fastening screw and the size of the fastening hole. Regardless of the deviation, it is fastened accurately to satisfy the required optical performance.

그리고 다른 실시예로 제 6 도와 같이 후경통(102)에 설치되어 항상 일정한 힘으로 안내보스(104)가 전경통(101)을 밀어주도록 캡(106)에 고무(205)를 일체형 구조로 할 수 있다.In another embodiment, the rubber 205 may be integrally formed on the cap 106 so that the guide boss 104 pushes the foreground cylinder 101 with a constant force at all times by being installed in the rearview barrel 102 as the sixth degree. have.

이와 같은 본 고안은 결합될 상대 경통을 항상 일정한 힘으로 밀어주어 광학계 성능에 악영향을 주는 여러요인들의 하나인 틸트 현상을 방지할 수 있어 광학설계시 요구되었던 광학성능을 만족시킬 수 있는 고안이다.The present invention is designed to satisfy the optical performance required in the optical design by preventing the tilt phenomenon, which is one of several factors that adversely affect the optical system performance by always pushing the relative barrel to be coupled with a constant force.
