일반적인 브이써알의 테이프 주행계에 있어서는, 제 1도에 도시한 바와같이,메인샤시(1)의 후방측에 헤드드럼(2)이 소정의 경사각을 두고 설치되고, 장기 헤드드럼(2)의 양측에 원호상의 로딩홈(3)(3')에는 공급측 가이드로울러(4)및 경사포스트(5),그리고 권취측 가이드로울러(6)및 경사포스트(7)를 각각 구비한 슬랜트베이스(8)(9)가 각각 삽입되고, 상기 슬랜트베이스(8)(9)의 하부 연결축(8a)(9a)에 별도의 구동수단에 의하여 연동되는 연결레버(10)(11)가 각각 연결되어, 상기 슬랜트베이스(8)(9)가 로딩홈(3)(3')을 따라 왕복이동이 가능하도록 설치되며, 상기 메인샤시(1)의 일측에 펀치레버(12)가 축핀(13)을 중심으로 회전가능하게 설치되고, 상기 펀치레버(12)의 상면 선단부에는 핀치로울러(14)가 축(14')올 중심으로 회전가능하게 축착되는 한편, 상기 펀치레버(12)의 후방측에 핀치로울러(14)가 압착되는 캡스턴 축(15)을 구비한 캡스턴모터(16)가 설치된 구조로 되어 있다.In the general V taper running system, as shown in FIG. 1, the head drum 2 is provided at a rear side of the main chassis 1 at a predetermined inclination angle, and both sides of the long-term head drum 2 are provided. In the circular grooves 3 and 3 'of the slant base 8, each having a supply side guide roller 4 and an inclined post 5, and a winding side guide roller 6 and an inclined post 7, respectively. (9) are respectively inserted, and the connecting levers (10) and (11), which are interlocked by separate driving means, are connected to the lower connecting shafts (8a) (9a) of the slant base (8) (9), respectively. The slant base (8) (9) is installed to reciprocate along the loading groove (3) (3 '), the punch lever 12 on one side of the main chassis (1) is the shaft pin (13) The pinch roller 14 is rotatably mounted around the shaft 14 'at the top end of the punch lever 12, and is rotatably installed at the center of the punch lever 12. The capstan motor 16 provided with the capstan shaft 15 in which the pinch roller 14 is crimped | bonded by the back side is provided.
상기 캡스턴모터(16)는 메인샤시(l)의 하부에 설치되며 캡스턴 축(15)이 메인샤시(1)의 상측으로 돌출되도록 고정되는바, 종래 기술에 의한 전형적인 캡스턴모터 고정장치의 일예를 첨부된 도면에 의하여 설명하면 다음과 같다.The capstan motor 16 is installed in the lower portion of the main chassis (l) and the capstan shaft 15 is fixed to protrude to the upper side of the main chassis (1), attached to an example of a typical capstan motor fixing device according to the prior art Referring to the drawings as follows.
제 1도 및 제2도에 도시한 바와같이, 캡스턴모터(15)의 스테이터판(17)은 메인샤시(1)의 하측으로 위치 하여, 권취측 슬랜트베이스(9)의 레버(11)와 간섭이 일어나지 않도록 메인샤시(11)의 하면과 일정간격(d)을 유지하기 위해 상면에 수개의 고정부채(18)가 고정되고, 상기 고정부재(18)는 메인샤시(1)의 상면에 고정나사(19)로 각각 고정되며, 캡스턴 축(15)의 하단부에 고정되는 로우터(20)는 별도의 로우터 이탈방지판(21]에 의하여 축방향 이탈이 방지되고, 축 하우징(22)은 헤드드럼(2)과 거의 동일한 높이로 세워져 고정된 구조로 되어있다.As shown in FIG. 1 and FIG. 2, the stator plate 17 of the capstan motor 15 is located below the main chassis 1, and the lever 11 of the winding side slant base 9 In order to prevent interference, several fixing liabilities 18 are fixed to the upper surface of the main chassis 11 to maintain a predetermined distance d, and the fixing member 18 is fixed to the upper surface of the main chassis 1. Each of the rotors 20 fixed to the screws 19 and fixed to the lower end of the capstan shaft 15 is prevented from being axially separated by a separate rotor release preventing plate 21, and the shaft housing 22 is a head drum. It is fixed at the same height as (2).
이와같은 구조로 캡스턴모터(16)가 고정된 일반적인 브이씨알의 테이프 주행계는 데크에 카세트가 안착되면 카세트의 테이프(T)는 공급 및 권취측 가이드로울러(4)(6)빛 경사포스트(5)(7)이 후방, 그리고 핀치호울러(14)의 후방에 위치하게 되므로 로딩신호가 인가되면, 공급 빛 권취측 슬랜트베이스(8)(9)는 메인샤시(1)의 로딩홈(3)(3’)을 따라 후방측으로 이동하게 되며, 이때 상기 슬랜트베이스(81(9)의 가이드로울러(41)(6)및 경사포스트(5)(7)는 테이프(T)를 이끌고 이동하여 헤드드럼(2)의 외주면에 테이프(T)픔 감게된다.In this structure, the tape running system of the general V-AL with the capstan motor 16 fixed to the deck, when the cassette is seated on the deck, the tape T of the cassette is supplied and wound on the guide rollers (4) and (6). (7) is located at the rear and rear of the pinch holder 14, so that when the loading signal is applied, the supply light winding side slant base (8) (9) is the loading groove (3) of the main chassis (1). (3 ') is moved to the rear side, wherein the guide rollers (41) (6) and the inclined posts (5) (7) of the slant base (81) (9) lead and move the tape (T) The tape T is wound around the outer circumferential surface of the head drum 2.
이와동시에 펀치레버(12)는 축핀(13)을 중심으로 반시계 방향으로 회동되어 테이프(T)를 캡스턴 축(15)에 소정의 압력으로 압착시키게 된다.At the same time, the punch lever 12 is rotated counterclockwise around the shaft pin 13 to press the tape T to the capstan shaft 15 at a predetermined pressure.
따라서 플레이모드에는 캡스턴모터(16)의 캡스턴 축(15)이 반시계 방향으로 회전됨으로써 테이프(T)를 권취릴측으로 이송시키게 된다.Therefore, in the play mode, the capstan shaft 15 of the capstan motor 16 is rotated counterclockwise to convey the tape T to the winding reel side.
그러나 상기한 바와같은 종래기술에 의하면, 테이프(T)의 로딩과 정중 권취측 슬랜트베이스(9)의 레버(11)가 스테이터판(17)과 간섭이 발생되지 않도록 일정간격(d)을 유치하여야 할 뿐만아니라 슬랜트베이스(9)와 이탈방지판(21)의 높이(H)로 인하여 데크의 두께가 두꺼워지는 단점이 있었으며, 또한 캡스턴모터(l6)의 스테이터판(17) 및 로우터(20)가 메인샤시(1)의 하부에 설치됨으로써 다른 부품과의 배치를 고려하여야 하는 등 설계가 용이하지 못한 문제점이 있었다.However, according to the prior art as described above, a certain interval d is attracted so that the lever 11 of the winding side slant base 9 during the loading of the tape T does not interfere with the stator plate 17. In addition, the thickness of the deck is thick due to the height (H) of the slant base (9) and the separation prevention plate (21), and also the stator plate (17) and the rotor (20) of the capstan motor (l6). ) Is installed in the lower part of the main chassis (1), there is a problem that the design is not easy, such as to consider the arrangement with other components.
본 발명은 상기한 바와같은 종래의 문제점을 해소하기 위하여 창안한 것으로, 캡스턴모터를 도립하여 헤드드럼의 높이보다 높지 않도록 함으로써 데크 문제를 얇게 함과 아울러 공간을 활용하여 다른부품과의 간섭을 염려할 필요없이 설계를 용이하게 할 수 있도록 구성한 것인바, 이하 본 발명을 첨부도면에 의하여 설명하면 다음과 같다.The present invention was devised to solve the conventional problems as described above. By inverting the capstan motor so as not to be higher than the height of the head drum, the deck problem can be made thinner and the space can be used to worry about interference with other parts. It is configured to facilitate the design without the need, the present invention will be described below with reference to the accompanying drawings.
제3도는 본 발명에 의한 브이씨알의 테이프 주행계를 보인 평면도이고, 제4도는 본 발명의 캡스턴모터고정장치를 보인 단면도로서, 이에 도시한 바와같이, 본 발명은 메인샤시(1)의 일정부위에 고정부재(31)를 수개의 고정나사(32)로 고정하고, 상기 고정부재(31)에 캡스턴모터(33)의 축 하우징(34)을 로우터(35) 및 스테이터판(36)이 상측을 향하도록 도립하여 고정하며,상기 캡스턴모터(33)의 캡스턴 축(37)은 메인샤시(1)의 상면에 접촉시켜 축방향의 힘이 지지되도록 구성한 것으로, 도면중 종래의 기술구성과 동일한 부분에 대하여는 동일 부호를 부여하였다.3 is a plan view showing a tape running system of V-Cal according to the present invention, and FIG. 4 is a cross-sectional view showing the capstan motor fixing device of the present invention. As shown in the drawing, the present invention provides a predetermined portion of the main chassis 1. The fixing member 31 to the fixing member 32, and the shaft housing 34 of the capstan motor 33 is attached to the fixing member 31 by the rotor 35 and the stator plate 36. The capstan shaft 37 of the capstan motor 33 is configured to be in contact with the upper surface of the main chassis 1 so as to be supported in an axial direction. The same code | symbol was attached | subjected about.
상기한 바와같이 구성되는 본 발명에 의한 캡스턴모터의 고정장치는 제4도에 도시한 바와같이 캡스턴모터(33)가 도립된 상태로 메인샤시(1)에 고정되으로 헤드드럼(2)의 높이보다 낮게되며, 기존의 슬랜트베이스(9)와 이탈방지판(21)의 높이(H)를 줄일 수 있으므로 데크의 전체적인 높이를 감소시킬 수 있는 것이다. 또한 캡스턴모터(33)의 로우터(20)및 스테이터판(17)을 권취측 가이드로울러(6)빛 슬랜트포스트(7)외상부에 놓이도록 하여 빈 공간을 활용함으로써 다른 부품과의 배치등을 염려할 필요없이 설계작업이 한층용이해진다.The capstan motor fixing apparatus according to the present invention configured as described above has the height of the head drum 2 fixed to the main chassis 1 with the capstan motor 33 inverted as shown in FIG. 4. It will be lower, so that the height (H) of the existing slant base (9) and the separation prevention plate 21 can be reduced the overall height of the deck. In addition, the rotor 20 and the stator plate 17 of the capstan motor 33 are placed on the outer side of the winding side guide roller (6) and the light slant post (7) so as to utilize the empty space to arrange the arrangement with other parts. There is no need to worry about design work.
한편, 캡스턴모터(33)의 통상적인 구동에 의하여 캡스턴 축(37)이 회전하게 되면,그 하단부가 메인샤시(l)의 상면에 접촉되므로 축방향의 힘이 지지되는 것이다.On the other hand, when the capstan shaft 37 is rotated by the normal driving of the capstan motor 33, the lower end portion is in contact with the upper surface of the main chassis (1) is to support the axial force.
이상에서 설명한 바와같은 본 발명은 캡스턴모터를 헤드드럼의 높이보다 낮도록 도립하여 고정함으로써 데크의 박형화에 기여하고 공간의 활용으로 설계의 어려움을 해소시키는 효과가 있다.As described above, the present invention contributes to the thinning of the deck by inverting and fixing the capstan motor to be lower than the height of the head drum, thereby eliminating design difficulties by utilizing space.
