본 고안은 브이씨알에 관한 것으로, 특히 헤드실린더와 메인베이스 사이의 진동전달 방지장치에 관한 것이다.The present invention relates to a V seed, and more particularly to a vibration transmission preventing device between the head cylinder and the main base.
통상 브이씨알에 있어서는 제1도에 도시한 바와 같이 테이프(1)가 메인베이스(2)에 설치된 관성롤(3), 소거헤드(4), 가이드롤(5), 경사포스트(6), 헤드실린더(7), 경사포스트(8), 가이드롤(9), 임피던스롤(10), 오디오 제어헤드(11)에 순차적으로 감기는 경로로 주행하게 되어있으며, 상기 헤드실린더(7)는 그 내부에 회전헤드(12)가 장착되고 회전하는 상부 회전실린더(13)와, 테이프 안내면(14)을 갖는 하부고정 실린더(15)와, 상부실린더(13)를 회전시키는 모터(16)와, 샤프트(17)로 구성되어 있다.In the case of ordinary V-Cal, as shown in FIG. 1, an inertial roll 3, an erasing head 4, a guide roll 5, an inclined post 6, and a head, on which the tape 1 is provided on the main base 2 The cylinder 7, the inclined post 8, the guide roll 9, the impedance roll 10, and the audio control head 11 are wound in order to travel in sequence, and the head cylinder 7 has its interior. An upper rotary cylinder 13 with a rotating head 12 mounted thereon, a lower fixed cylinder 15 having a tape guide surface 14, a motor 16 for rotating the upper cylinder 13, and a shaft ( 17).
이러한 헤드실린더(7)는 메인베이스(2)에 고정나사(18)로 직접 체결하게 되며, 상기 제1도와 같이 테이프(1)가 주행할 때에 그 테이프(1)는 하부 실린더(15)에 형성된 테이프 안내면(14)을 따라 주행하게 되며 모터(16)에 의하여 회전하는 상부실린더(13)와 함께 상부실린더(13)에 장착된 비디오 헤드(12)가 회전하면서 테이프(1)에 영상신호를 기록재생한다.The head cylinder 7 is directly fastened to the main base 2 with a set screw 18. When the tape 1 travels as shown in FIG. 1, the tape 1 is formed in the lower cylinder 15. The video head 12 mounted on the upper cylinder 13 rotates along with the tape guide surface 14 and the upper cylinder 13 rotated by the motor 16 to record an image signal on the tape 1. Play it.
이때 모터(16)의 자기적, 전기적 특성에 의해 회전 변동이 생겨 헤드실린더(7)에 진동이 유발되며 이 진동이 메인베이스(2)에 전달되어 테이프(1)의 주행상태에 진동을 일으키기도 하고 역으로 메인베이스(2)의 주행계에 가하여지는 외부의 충격등에 의해 진동이 발생하여 이 진동이 헤드실린더(7)에 전달되어 화면 떨림, 지터, 와우 플러터 등의 성능악화를 가져오게 된다.At this time, rotational variation occurs due to the magnetic and electrical characteristics of the motor 16, causing vibration to the head cylinder 7, which is transmitted to the main base 2 to cause vibration in the running state of the tape 1. On the contrary, vibration is generated by an external impact applied to the traveling system of the main base 2, and the vibration is transmitted to the head cylinder 7, resulting in deterioration of screen shake, jitter, and wow flutter.
이와 같이 종래에는 헤드실린더(7)와 메인베이스(2)를 직접 체결하였기 때문에 헤드실린더(7)의 모터(16)에 의한 회전진동이나 비디오헤드(12)와 테이프(1)의 충격등에 의한 진동이 메인베이스(2)에 전달되어 테이프 주행상태가 안정되지 못하거나 메인베이스(2)에서 발생하는 진동이 헤드실린더(7)에 전달되어 재생 및 녹화성능이 저하되는 결함이 있었으며 특히 이러한 현상은 소형, 경량화 제품인 캠코더에 빈번히 일어나는 현상이며 제품 설계에 문제로 되고 있다.As described above, since the head cylinder 7 and the main base 2 are directly fastened, rotational vibration by the motor 16 of the head cylinder 7 or vibration due to the impact of the video head 12 and the tape 1 and the like. There was a defect that the tape running state is not stabilized by the main base 2 or the vibration generated in the main base 2 is transmitted to the head cylinder 7, thereby reducing the playback and recording performance. However, this phenomenon occurs frequently in camcorders, which are lightweight products, and is a problem in product design.
본 고안은 이와 같은 종래의 결함을 해소하기 위하여 안출한 것으로, 헤드실리더와 메인베이스 사이에 진동흡수제를 삽입하여 체결하므로 진동전달을 방지할 수 있는 전동전달 방지장치를 제공하려는 것이다.The present invention has been made in order to solve such a conventional defect, it is to provide a transmission transmission preventing device that can prevent vibration transmission by inserting the vibration absorbing agent between the head cylinder and the main base.
이하, 이러한 본 고안의 일실시예를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings an embodiment of the present invention as follows.
제3도 및 제4도에 도시한 바와 같이, 메인베이스(2)에 형성된 통공(19)에 헤드실린더(7)의 모터(16) 하측부분이 삽입되고, 통공(19) 주위의 수개의 고정보스(20)에 하부에서 끼워지는 고정나사(18)로 헤드실린더(7)가 체결되는 것에 있어서, 상기 메인베이스(2)의 통공(19) 둘레에 수개(도면에는 3개로 도시됨)의 돌출부(21)를 일정간격으로 형성하고 그 돌출부(21) 외측에는 안내지지홈(22)을 형성하며, 상기 각 돌출부(21)에는 자형 단면을 가지는 고무등의 진동흡수제(23)를 삽입하는 동시에 각 진동흡수제(23)의 일측단부(24)를 상기 안내지지홈(22)에 각각 삽입하고, 각 진동흡수제(23)위에 헤드실린더(7)가 접촉 고정되게한 것이다.As shown in FIG. 3 and FIG. 4, the lower part of the motor 16 of the head cylinder 7 is inserted into the through hole 19 formed in the main base 2, and several fixing around the through hole 19 is carried out. In the case where the head cylinder 7 is fastened by a fixing screw 18 fitted from the lower part to the boss 20, several projections (shown as three in the figure) are formed around the through hole 19 of the main base 2. (21) are formed at regular intervals and the guide support grooves (22) are formed outside the protrusions (21), and each of the protrusions (21) is inserted with a vibration absorber (23) such as rubber having a magnetic cross section. One end 24 of the vibration absorber 23 is inserted into the guide support grooves 22, respectively, and the head cylinders 7 are fixed to each other on the vibration absorbents 23.
이와 같이 된 본 고안은 헤드실린더(7)를 체결하면서 메인베이스(2)의 통공(19) 주위에 형성한 수개의 돌출부(21)에 진동흡수제(23)를 삽입한 후 각 진동흡수제(23)위에 헤드실린더(7)를 재치시키고 각 고정보스(20)에 끼워지는 고정나사(18)로 그 헤드실린더(7)를 체결한다.According to the present invention, the vibration absorber 23 is inserted into the several protrusions 21 formed around the through hole 19 of the main base 2 while the head cylinder 7 is fastened. The head cylinder 7 is placed thereon, and the head cylinder 7 is fastened with a fixing screw 18 fitted to each high information source 20.
헤드실린더(7)를 조립하기전에는 진동흡수제(23)가 제4도에 도시한 A 상태이나, 조립후에는 진동흡수제(23)가 탄성적 성질에 의해 수축되어 B상태로 유지된다.Before assembling the head cylinder 7, the vibration absorber 23 is in the A state shown in FIG. 4, but after assembly, the vibration absorber 23 is contracted by the elastic property and maintained in the B state.
이와같이 조립된 상태에서 브이씨알 동작시 모터(16)의 전기적, 자기적 특성에 의하여 헤드실린더(7)에 진동이 일어나고 또 메인베이스(2)에 외부 충격에 의해 진동이 일어나면, 본 고안은 헤드실린더(7)와 메인베이스(2)의 돌출부(21) 사이에 수개의 진동흡수제(23)가 삽입되어 있기 때문에 그 진동흡수제(23)가 헤드실린더(7)및 메인베이스(2)의 진동에너지를 흡수하여 열에너지로 흡수하여 감쇠시켜 버리므로 진동이 거의 전달되지 않는다.If the vibration occurs in the head cylinder (7) due to the electrical and magnetic characteristics of the motor 16 in the assembled state in the assembled state as described above and the vibration occurs by the external impact on the main base (2), the present invention head cylinder Since several vibration absorbers 23 are inserted between the 7 and the protruding portion 21 of the main base 2, the vibration absorbers 23 absorb the vibration energy of the head cylinder 7 and the main base 2. Absorption is absorbed by thermal energy and attenuated, so vibration is hardly transmitted.
종래의 브이씨알 특히 캠코더(카메라 일체형 브이씨알)에서는 헤드실린더의 진동이 메인베이스 조립체에 전달되거나 메인베이스의 주행시 진동이 헤드실린더에 전달되어 테이프의 주행상태를 불안정하게 하여 화질 특히 화면떨림, 지터, 와우 플러터 등을 악화시키는 것이나, 본 고안에서는 메인베이스와 헤드실린더 사이의 진동흡수제에 의해 진동의 전달이 방지되어 테이프의 주행상태가 안정되므로 양호한 화질을 얻게되는 이점이 있다.In conventional V-als, especially camcorders (cameras with integrated cameras), vibration of the head cylinder is transmitted to the main base assembly, or vibrations are transmitted to the head cylinder when the main base is driven, which destabilizes the driving state of the tape, such as image quality, screen jitter, jitter, In order to deteriorate the wow flutter or the like, in the present invention, vibration is prevented from being transmitted by the vibration absorber between the main base and the head cylinder, so that the running state of the tape is stabilized.
