It is specified that it is comprised so that operation may be stopped.
이하 본 고안에 따른 테이프 이송기구의 테이프 보호장치의 바람직한 일 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a tape protection device of the tape transfer mechanism according to the present invention will be described in detail.
제2도 내지 제3도에 도시된 바와 같이 본 고안에 따른 테이프 이송기구의 테이프 보호장치는, 테이프(T)에 기록된 기록을 읽어 내는 헤드드럼(1)과, 테이프 공급측 위치에는 카세트(c)의 릴구동테이블(2)로부터 인출되는 테이프(T)를 상기 헤드드럼(1)에 안내하는 공급측 안내수단(3a)(3b)(3c)(3d) 및 소거헤드(4)가 마련된다.As shown in Figs. 2 to 3, the tape protection device of the tape transport mechanism according to the present invention includes a head drum 1 for reading out a record recorded on the tape T, and a cassette c at a tape supply side. Supply side guide means (3a) (3b) (3c) (3d) and an erasing head (4) for guiding the tape (T) withdrawn from the reel drive table (2) of the head) to the head drum (1) are provided.
또한 테이프(T) 권취측의 위치에는 릴구동테이블(2)로부터 안내되는 테이프(T)를 테이크업(5)에 감기도록 안내하는 안내수단(3a')(3b')(3c')(3d')이 마련되며, 상기 안내수단(3a')(3b')(3c')(3d')으로부터 안내되는 테이프(T)는 음성콘트롤헤드(6)를 거쳐 테이크업(5)으로 안내되며 상기 음성콘트롤헤드(6)와 테이크업(5) 사이에는 테이프(T)에 이송력을 인가하는 캡스턴축(7) 및 핀치롤러(8)가 마련된다.In addition, the guide means 3a ', 3b', 3c '(3d) for guiding the tape T guided from the reel drive table 2 to the take-up 5 at the position on the winding side of the tape T. ') Is provided, and the tape T guided from the guide means 3a', 3b ', 3c', 3d 'is guided to the take-up 5 via the voice control head 6 and the A capstan shaft 7 and a pinch roller 8 for applying a feed force to the tape T are provided between the voice control head 6 and the take-up 5.
특히 상기 핀치롤러(8)에는 핀치롤러(8)의 캡(8a)과 일체형으로 테이프(T) 이송방향에 대한 출구측에 개구를 가진 형상의 홀더(8b)가 마련되며, 상기 홀더(8b)의 서로 대향하고 있는 내측면에는 감지수단으로서 센서가 구비되어 있는바 즉, 발광소자(8c)와 수광소자(8d)가 마련되어 있다.In particular, the pinch roller 8 is provided with a holder 8b having an opening on the outlet side in the tape T conveyance direction integrally with the cap 8a of the pinch roller 8, and the holder 8b. Sensors are provided as sensing means, i.e., light emitting element 8c and light receiving element 8d are provided on the inner side surfaces facing each other.
상기와 같이 구성된 본 고안에 따른 테이프 이송기구의 테이프 보호장치에 카세트(c)의 릴구동테이블(2)로부터 인출된 테이프(T)는 공급측안내수단(3a)(3b)(3c)(3d)에 의해 헤드드럼(1)의 외주면에 일정 경사각으로 접촉된 후, 다수개의 안내수단(3a')(3b')(3c')(3d')에 의해 음성콘트롤헤드(6)를 통과한다. 그리고 상기 음성콘트롤헤드(6)를 통과한 테이프(T)는, 상호압착되어 있는 캡스턴축(7) 및 핀치롤러(8) 사이를 통과하여 일정한 이송력을 인가받아 테이크업(5)에 감기게 된다.The tape T drawn out from the reel drive table 2 of the cassette c in the tape protection device of the tape transfer mechanism according to the present invention configured as described above is supplied to the supply side guide means 3a, 3b, 3c, 3d. After contacting the outer circumferential surface of the head drum 1 at a predetermined inclination angle, the voice control head 6 passes through the plurality of guide means 3a ', 3b', 3c 'and 3d'. Then, the tape T passing through the voice control head 6 passes between the capstan shaft 7 and the pinch roller 8 which are mutually compressed to receive a constant feed force and to be wound on the take-up 5. do.
이때 기기의 이상 즉 아이들러(idler)(도시되지 않음)나 클러치(도시되지 않음)의 이상이 발생하면 테이크업(5)이 테이프(T)를 감지못하는 경우가 발생한다.At this time, if an abnormality of the device, that is, an idler (not shown) or a clutch (not shown) occurs, the take-up 5 may not detect the tape T.
이로 인해서는 캡스턴축(7)과 핀치롤러(8) 사이에서 테이프(T)의 처짐이 발생되는데, 이 테이프(T)의 처짐을 핀치롤러(8)의 캡(8a)에 일체로 마련된 홀더(8b)의 센서에 의해 감지하여 기기의 동작을 멈추게 하여 테이프(T)가 파손되는 것을 막아주는 것이다.This causes sagging of the tape T between the capstan shaft 7 and the pinch roller 8, and the sagging of the tape T is integrally provided with the cap 8a of the pinch roller 8 ( It is detected by the sensor of 8b) to stop the operation of the device to prevent the tape (T) from being damaged.
이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.
핀치롤러(8)의 캡(8a)과 일체로 마련된 홀더(8b)에는 센서가 설치되어 있다. 즉, 서로 대향되는 내면에 발광소자(8c)와 수광소자(8d)가 마련되어 있어, 기기의 정상동작시에는 발광소자(8c)로 부터 빛이 발광되어 수광소자(8d)가 이를 받아들이는 것이다. 하지만 기기의 오동작으로 캡스턴축(7)과 핀치롤러(8)사이에서 테이프(T)의 처짐이 발생하게 되면 제2도에서 보는 바와 같이 테이프(T)의 처진부분이 발광소가(8c)와, 수광소자(8d)사이에 놓이게 되고 이에 따라 발광소자(8c)로부터 발광되는 빛을 수광소자(8d)에서 받아들이지 못하게 됨으로써 이를 감지하여 기기의 동작을 멈추게 하여 테이프(T)가 더이상 처짐이 발생되지 않도록 막아주는 것이다.The sensor is attached to the holder 8b integrally provided with the cap 8a of the pinch roller 8. That is, the light emitting element 8c and the light receiving element 8d are provided on the inner surfaces facing each other, so that light is emitted from the light emitting element 8c during normal operation of the device, and the light receiving element 8d receives it. However, if the deflection of the tape T occurs between the capstan shaft 7 and the pinch roller 8 due to malfunction of the device, as shown in FIG. 2, the deflection portion of the tape T is associated with the light emitting device 8c. Since the light is emitted from the light emitting element 8c, the light receiving element 8d does not receive the light from the light receiving element 8d, and thus detects this and stops the operation of the device so that the tape T no longer sags. It is to prevent.
상기와 같이 기기의 오동작으로 발생되는 테이프(T)의 처짐을 선속히 감지함으로써, 테이프(T)가 처져 기기내에 감기는 것을 방지함으로써 이에 따라 발생되는 기기의 고장 또는 파손을 방지할 수 있다.By detecting the deflection of the tape T caused by malfunction of the device as described above, it is possible to prevent the tape T from sagging and being wound in the device, thereby preventing failure or breakage of the device.
