* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

3, 3' : 로딩베이스 5, 5' : 가이드로울러3, 3 ': loading base 5, 5': guide roller

7, 7' : 경사포스트 8 : 헤드드럼7, 7 ': post tilt 8: head drum

9 : 로울러9: roller

본 고안은 직경 41,33mm의 헤드드럼을 사용하는 소형화 및 경량화 된 브이씨알에 관한 것으로, 특히 경사포스트의 하측부의 로울러를 유착하여 로딩베이스의 유동시 경사포스트 대신에 상기 로울러를 헤드드럼에 접촉되게 함으로써 경사포스트의 접촉에 의한 헤드드럼의 손상을 방지할 수 있게 한 헤드드럼의 손상방지장치에 관한 것이다.The present invention relates to a miniaturized and lightweight V-Cal using a head drum with a diameter of 41,33mm. In particular, the rollers are attached to the lower part of the inclined post so that the roller contacts the head drum instead of the inclined post when the loading base flows. The present invention relates to a head drum damage preventing device that can prevent head drum damage due to contact of an inclined post.

일반적으로 사용되는 브이씨알에는 직경 62mm의 헤드드럼을 사용하고 있으나, 근간에는 데크의 소형화 및 경량화의 추세에 따라서 직경 41,33mm의 소형헤드드럼을 사용하고 있다.In general, the V-Cal has a head drum with a diameter of 62mm, but a small head drum with a diameter of 41,33mm is used in accordance with the trend of miniaturization and weight reduction of the deck.

이와 같은 소형 헤드드럼을 채용한 브이씨알에서는 좁은 공간에 많은 부품이 착설되어 있어 테이프의 로딩동작증에 부품의 접촉으로 인한 손상을 방지할 수 있도록 구성시켜야 한다.In the V-Cal employing such a small head drum, many parts are installed in a narrow space so that the damage due to the contact of the parts may be prevented due to the loading behavior of the tape.

상기한 바와 같은 소형 헤드드럼을 사용한 브이씨알의 일예를 설명하면 다음과 같다.An example of V-AL using the small head drum as described above is as follows.

제1도 및 제2도에 도시한 바와 같이, 카세트(도시되지 않음)의 장착이 완료되면, 베이스플레이트(1)의 저면에서 판스프링(2)으로 지지된 로딩베이스(3)(3')는 카세트의 테이프(도시되지 않음)을 인출하여 베이스플레이트(1)의 양측 안내홈(4)(4')을 따라서 이동하게 되며, 로딩베이스(3)(3')의 가이드러울러(5)(5') 하측부가 안내홈 (4)(4')의 일측단부에 고정된 V스토퍼(6)(6')에 걸리게 되면, 로딩 베이스(3)(3')의 이동은 정지되고, 로딩베이스(3)(3')의 가이드로울러(5)(5') 및 경사포스트(7)(7')에 의하여 하부에 가이드라인(8a)이 형성된 헤드드럼(8)에 접촉되는 테이프의 주행을 안내하게 된다.As shown in FIGS. 1 and 2, when the mounting of the cassette (not shown) is completed, the loading base 3 (3 ') supported by the leaf spring 2 at the bottom of the base plate 1 Draws a tape (not shown) of the cassette and moves along the guide grooves 4 and 4 'on both sides of the base plate 1, and the guide roller 5 of the loading base 3 and 3'. (5 ') When the lower part is caught by the V stopper 6 (6') fixed to one end of the guide groove (4) (4 '), the movement of the loading base (3) (3') is stopped and the loading Traveling of the tape in contact with the head drum 8 formed with the guideline 8a at the bottom by the guide rollers 5, 5 'and the inclined posts 7, 7' of the base 3, 3 '. Will guide you.

그러나, 이와 같이 데크가 소형화 된 종래의 경우에는 테이프의 로딩시, 헤드드럼(8)에 인접하여 로딩베이스(3)(3')가 안내홈(4)(4')을 따라서 이동하게 되며, 이때 테이프의 텐션등으로 로딩베이스(3) (3')는 좌, 우 유동이 발생하게 된다.However, in the conventional case where the deck is downsized, when loading the tape, the loading base (3) (3 ') is moved along the guide groove (4) (4') adjacent to the head drum (8), At this time, the left and right flow of the loading base 3 (3 ') occurs due to the tension of the tape.

따라서 제2도에 가상선으로 도시한 바와 같이, 상부드럼(8)의 일측부에 로딩베이스(3)(3')의 경사포스트(7)(7')가 접촉됨으로써 헤드드럼(8)이 손상되는 문제점이 있었다.Therefore, as shown by the virtual line in FIG. 2, the inclined posts 7 and 7 ′ of the loading base 3 and 3 ′ come into contact with one side of the upper drum 8 so that the head drum 8 is closed. There was a problem of being damaged.

따라서 본 고안은 이와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로, 경사포스트의 하측부의 로울러를 회전가능하게 결합하여 로딩베이스의 좌, 우 유동시 헤드드럼에 경사포스트가 접촉되지 않게 하고, 경사포스트에 유착된 로울러갈 접촉되게 함으로써 경사포스트의 접촉에 의한 헤드드럼의 손상을 방지할 수 있도록 구성한 것인 바, 이를 첨부된 도면에 의하여 설명하면 다음과 같다.Therefore, the present invention has been devised in order to solve such a conventional problem, so that the rollers of the lower part of the inclined post are rotatably coupled so that the inclined post is not in contact with the head drum during the left and right flow of the loading base. It is configured to prevent damage to the head drum due to the contact of the inclined post by contacting the roller to be adhered to, as described with reference to the accompanying drawings.

제1도 및 제3도 및 제4도에 도시한 바와 같이, 가이드로울러(5)(5') 및 경사 포스트(7)(7')를 구비한 로딩베이스(3)(3')가 헤드드럼(8)이 고정된 베이스플레이트 (1)의 안내홈(4)(4')을 따라서 이동되는 것에 있어서, 상기 경사포스트(7)(7')의 하측부에 경사포스트(7)(7')가 헤드드럼(8)에 접촉되는 것을 방지하기 위한 로울러(9)를 회전가능하게 결합하여서 된 것으로, 도면중 미설명 부호는 종래의 경우와 동일하게 부여하였다.As shown in Figs. 1 and 3 and 4, the loading bases 3, 3 'with guide rollers 5, 5' and inclined posts 7, 7 'are heads. In the drum 8 being moved along the guide grooves 4 and 4 'of the fixed base plate 1, the inclined posts 7 and 7 below the inclined posts 7 and 7'. ') Is rotatably coupled to the roller (9) for preventing the head drum (8), the reference numerals in the drawings are given in the same manner as in the conventional case.

이와 같이 된 본 고안은 테이프의 로딩시 베이스플레이트(1)의 안내홈(4)(4')을 따라서 이동되는 로딩베이스(3)(3')가 좌, 우 유동하게 되면, 제3도에 도시한 헤드드럼 (8)의 (가)부분 즉, 가이드라인(8a)의 하측부에 경사포스트(7)(7')의 로울러(9)가 접촉하게 되어 헤드드럼(8)에는 경사포스트(7) (7')가 접촉되지 않게 함으로써 경사포스트(7)(7')의 접촉에 의한 헤드드럼(8)의 손상을 방지하게 되는 효과가 있다.The present invention as described above, when the loading base (3) (3 ') that is moved along the guide groove (4) (4') of the base plate 1 during the loading of the tape flows left and right, The roller 9 of the inclined posts 7 and 7 'comes into contact with the (a) part of the illustrated head drum 8, i.e., the lower side of the guide line 8a. 7) There is an effect that the head drum 8 is prevented from being contacted by the inclined posts 7 and 7 'by preventing the 7' from coming into contact.
