본 고안은 브이씨알의 고속탐사용 테이프 가이드장치에 관한 것으로, 특히 펑션플레이트에 접동되어 테이프를 음성제어헤드에 접촉시켜주는 두 개의 연결레버를 설치하여 음성제어헤드에서 테이프에 기록한 신호를 다시 음성제어헤드에서 검출할 수 있게 함으로써 별도의 탐색센서를 이용하지 않고도 고속탐사시 테이프의 원하는 위치를 정확하게 찾을 수 있게 한 고속탐사용 테이프가이드장치에 관한 것이다.The present invention relates to a high speed exploration tape guide device of V-Cal. In particular, two control levers, which slide on a function plate to contact a tape with a voice control head, are installed for voice control of the signals recorded on the tape by the voice control head. The present invention relates to a high speed search tape guide device that enables a head to detect a desired position of a tape accurately during a high speed search without using a separate search sensor.

종래에는 테이프에 기록된 프로그램을 찾아내기 위하여 테이프의 소정위치에 전폭소거헤드로 저주파 신호를 기록해둔 다음 별도의 탐색센서를 이용하여 이를 다시 찾아내게 하는 방법이 통상 이용되고 있다.Conventionally, in order to find a program recorded on a tape, a low frequency signal is recorded at a predetermined position of the tape with a full width erasing head, and then a method of finding it again using a separate search sensor is commonly used.

이러한 방법을 이용하는 종래의 메카니즘을 제1도에 도시하였다. 여기서 녹화(재생)시의 주행경로는 가상선으로 도시하였고, 빨리 감기, 되감기 모드시의 주행경로는 실선으로 도시하였다. 즉, 녹화(재생)모드에서는 구동모터가 회전하여 구동캠(도시되지 않음)을 회전시키게 되면 펑션플레이트(1)가 우측으로 이동하면서 텐션아암(2) 및 핀치로울러아암(3)을 가상선으로 도시한 바와 같이 반시계방향으로 회전시켜 텐션포스트(2')는 카세트(4)로부터 테이프(5)를 인출하고 핀치로울러(3')는 캠스턴축(6)에 밀착되며, 양측의 슬랜트포스트 조립체(7)(7')가 테이프(5)를 끌고 로딩패스(8)(8')를 타고 이송되어 헤드드럼(9)에 일정각으로 감아주게 된다.The conventional mechanism using this method is shown in FIG. Here, the driving route at the time of recording (reproduction) is shown by the virtual line, and the driving route at the fast forward and rewind mode is shown by the solid line. That is, in the recording (playback) mode, when the drive motor is rotated to rotate the drive cam (not shown), the function plate 1 moves to the right, and the tension arm 2 and the pinch roller arm 3 are moved to the virtual line. As shown in the figure, by rotating in a counterclockwise direction, the tension post 2 'pulls out the tape 5 from the cassette 4, and the pinch roller 3' is in close contact with the camston shaft 6, and both slants The post assemblies 7, 7 ′ are pulled by the tape 5 and transported in the loading paths 8, 8 ′ and wound around the head drum 9 at an angle.

이때, 공급릴(도시되지 않음)로부터 풀려나오는 테이프(5)는 가이드포스트(10), 가이드롤러(11), 전폭소거헤드(12), 헤드드럼(9), 음성제어헤드(13), 캡스턴축(6)과 핀치로울러(3')를 거쳐 가이드포스트(14)(15), 권취릴(도시되지 않음)에 감기는 상태가 된다. 그리고, 카세트(4)의 중앙측 개구부(4a) 내측에 인접하여 탐색센서(16)가 설치되어 있다. 이와 같은 녹화(재생)모드에서 전폭소거헤드(12)에 의하여 테이프(5)의 일정부위에 신호를 기록한 다음, 이를 다시 찾아내고자 하는 경우에는 빨리감기 또는 되감기 모드에서 카세트(4)의 중앙측개구부(4a)에 인접하여 위치한 탐색센서(16)로서 찾아내게 되는데 이때에는 테이프(5)가 가이드포스트(10), 탐색센서(16), 가이드포스트(15)의 위치가 되어 테이프(5)를 고속회전시키면서 전폭소거헤드(12)로 기록해둔 신호를 탐색센서(16)가 검출하게 함으로써 원하는 화면을 찾을 수 있게 된다.At this time, the tape 5 released from the supply reel (not shown) includes a guide post 10, a guide roller 11, a full width erase head 12, a head drum 9, a voice control head 13, a capstan It is in a state of being wound around the guide posts 14 and 15 and the winding reel (not shown) via the shaft 6 and the pinch roller 3 '. The search sensor 16 is provided adjacent to the inside of the center side opening 4a of the cassette 4. In such a recording (playback) mode, when the signal is recorded on a predetermined portion of the tape 5 by the full-width erasing head 12, and when it is desired to find it again, the central side opening of the cassette 4 in the fast-forward or rewind mode It is found as a search sensor 16 located adjacent to (4a), in which case the tape (5) is the position of the guide post 10, the search sensor 16, the guide post (15) to the high speed tape (5) By rotating the search sensor 16 detects the signal recorded by the full-width erasing head 12 while rotating, it is possible to find a desired screen.

그러나, 상기한 종래의 방법에서는 테이프(5)에 신호를 기록할 때는 녹화(재생)모드의 주행경로상에 위치하는 전폭소거헤드(12)를 이용하여 기록을 하고, 검출시에는 빨리감기 또는 되감기 모드의 주행경로상에 위치하는 별도의 탐색센서(16)를 사용하게 되므로 전폭소거헤드(12)와 탐색센서(16)간의 위치차에 의한 오차가 발생되어 테이프의 정확한 위치를 찾을 수 없게되는 문제점을 안고 있었다.However, in the conventional method described above, when recording a signal on the tape 5, recording is performed by using the full-width erasing head 12 located on the driving path of the recording (playback) mode, and fast forwarding or rewinding upon detection. Since a separate search sensor 16 located on the driving path of the mode is used, an error occurs due to a position difference between the full width erasing head 12 and the search sensor 16, and thus, the exact position of the tape cannot be found. Was hugging.

본 고안은 종래의 이러한 문제점을 해소하고자 안출한 것으로, 녹화(재생)모드에서 음성제어헤드를 이용하여 테이프에 신호를 기록할 수 있게 하고, 펑션플레이트에 의하여 연동되어 테이프를 고속주행상태로 음성제어헤드에 접속시켜줄 수 있게 하는 레버를 설치하여 고속주행상태에서 음성제어헤드가 이를 다시 검출할 수 있게 함으로써 신호의 기록과 검출을 음성제어헤드로서 동시에 수행할 수 있도록 한 것인바, 이를 첨부도면에 의하여 상세히 설명하면, 다음과 같다.The present invention has been made to solve such a problem in the related art, and it is possible to record a signal on a tape using a voice control head in a recording (playback) mode, and interlocked by a function plate to control the tape in a high speed driving state. By installing a lever that connects to the head so that the voice control head can detect it again in a high-speed driving state so that recording and detection of signals can be performed simultaneously as the voice control head. In detail, it is as follows.

제2도 내지 제4도에 도시한 바와 같이, 구동캠(20)의 캠홈(21)에 일측단부의 작동핀(22)이 끼워져 연동되는 펑션플레이트(23)의 타측단부에 연결핀(24)을 입설하고, 일측단부에 상기 연결핀(24)이 끼워지는 연결홈(25a) 및 경사면(25b)이 구비되고 타측단부에 걸림돌부(25c) 및 캠면(25d)을 가지는 연결레버(25)를 베이스(도시되지 않음)상에 힌지핀(25')으로 축착하며, 연결레버(25)의 인접부에는 일측단부에 핀(26)이 돌설되어 상기 연결레버(25)의 걸림돌부(25c) 및 캠면(25d)에 접동하는 인출레버(27)를 힌지핀(27')으로 축착하여 반시계방향의 회전력을 갖도록 코일스프링(28)으로 탄지시키고, 인출레버(27)의 타측단부에는 카세트(41)의 중앙측개구부(41a)에 위치하는 인출핀(27a)을 입설하여서 된 것으로 이외의 구성은 종래와 동일하다.As shown in FIGS. 2 to 4, the operation pin 22 of one end is inserted into the cam groove 21 of the driving cam 20 so that the connection pin 24 is connected to the other end of the function plate 23. A connection groove 25a and an inclined surface 25b into which the connecting pin 24 is fitted at one end thereof, and a connecting lever 25 having a locking protrusion 25c and a cam surface 25d at the other end thereof. It is fixed to the base (not shown) by a hinge pin (25 '), the pin 26 is protruded at one end in the adjacent portion of the connecting lever 25, the locking projection 25c and the connecting lever 25 The take-out lever 27 sliding on the cam surface 25d is crimped with the hinge pin 27 'and held by the coil spring 28 so as to have a counterclockwise rotation force, and the cassette 41 is provided at the other end of the take-out lever 27. The draw-out pin 27a located in the center side opening part 41a of () is built in, and the structure other than that is the same as before.

이와 같은 본 고안이 설치된 데크에 카세트(41)를 장착하면 제2도에 도시한 바와 같이 테이프(42)는 카세트(41)의 내부양측에 설치된 가이드포스트(31)(37)에 안내된 상태로 있게되며, 이와 같은 상태에서 녹화(재생)를 하는 경우에는 제4도에 도시한 바와 같이 슬랜트포스트조립체(29)(29')가 로딩패스(30)(30')를 타고 테이프(42)를 끌고나가 헤드드럼(34)에 일정각도만큼 감아주게 되면 녹화(재생)모드가 되며, 이때 테이프(42)에 음성제어헤드(35)에 의하여 신호를 기록할 수 있게된다.When the cassette 41 is mounted on the deck provided with the present invention, as shown in FIG. 2, the tape 42 is guided to guide posts 31 and 37 provided on both sides of the cassette 41. In the case of recording (reproducing) in such a state, as shown in FIG. 4, the slant post assembly 29 (29 ') rides the loading paths 30, 30' and the tape 42 After dragging and winding the head drum 34 by a predetermined angle, the recording (playback) mode is performed. At this time, the signal can be recorded by the voice control head 35 on the tape 42.

이와 같이 테이프(42)에 기록된 신호를 상기와 같은 녹화(재생)모드에서 찾아내는 것은 시간적으로 불편한 일이므로 고속주행모드에서 신호를 검출하는 고속탐사를 하게 되는바, 이를 제3도에 참조하여 구체적으로 설명하면 다음과 같다. 구동모터(도시되지 않음)의 회전력을 받은 구동캠(20)이 시계방향으로 회전하게 되는 그 구동캠(20)의 캠홈(21)에 작동핀(22)으로 연결된 펑션플레이트(23)가 우측으로 이동하게 되고, 이와동시에 펑션플레이트(23)의 우측상단에 돌설된 연결핀(24)이 일측단부의 연결홈(25a)에 끼워진 연결레버(25)가 힌지핀(25')을 중심으로 반시게방향의 회전을 하여 타측단부의 걸림돌부(25c)가 인출레버(27)의 핀(26)을 밀어주게 된다. 이에 따라 인출레버(27)는 코일스프링(28)의 탄성을 이기고 힌지핀(27')을 중심으로 시계방향의 회전을 하면서 카세트(41)의 중앙측 개구부(41a) 내측에 위치하고 있는 인출핀(27a)이 테이프(42)를 끌고나와 음성제어헤드(35)에 접속시켜주게 되므로 테이프(42)를 고속으로 주행시키면서 상기한 바와 같이 테이프(42)에 미리 기록해둔 신호를 음성제어헤드(35)로 신호를 검출하여 소정의 위치를 찾아낼 수 있게된다.As such, it is inconvenient in time to find a signal recorded on the tape 42 in the recording (reproducing) mode as described above. Therefore, a high-speed search for detecting a signal in the high-speed driving mode is performed. Explained as follows. The function plate 23 connected to the cam groove 21 of the drive cam 20 to which the drive cam 20 is subjected to the rotational force of the drive motor (not shown) by the operating pin 22 is turned to the right. At the same time, the connecting lever 25 protruding from the right upper end of the function plate 23 is inserted into the connecting groove 25a at one end thereof so that the hinge pin 25 'is centered on the hinge pin 25'. The locking protrusion 25c of the other end pushes the pin 26 of the pullout lever 27 by rotating in the direction. Accordingly, the withdrawal lever 27 overcomes the elasticity of the coil spring 28 and rotates clockwise around the hinge pin 27 'so that the withdrawal pin 27 is located inside the central opening 41a of the cassette 41 ( 27a) pulls out the tape 42 and connects it to the voice control head 35, so that the signal 42 previously recorded on the tape 42 as described above is driven while driving the tape 42 at high speed. By detecting a signal, it is possible to find a predetermined position.

이와 같은 상태에서 구동모터가 계속 회전하여 구동캠(20)을 회전시키게 되면 펑션플레이트(23)는 우측으로 더 이동을 하게되어 연결핀(24)이 연결레버(25)의 연결홈(25a)으로부터 빠져나온 다음 펑션플레이트(23)의 이동방향과 수평을 이루고 있는 연결레버(25)의 경사면(25b)에 접하게 됨과 동시에 인출레버(27)의 핀(28)은 연결레버(25) 타측단부의 걸림돌부(25c)를 지나 캠면(25d)에 접촉하게 되어 테이프(42)는 음성제어헤드(35)로부터 약간 떨어진 상태가 되면서 연결레버(25)와 인출레버(27)는 더 이상의 회전을 하지 않고 정지상태를 유지하게 되고, 이와 같은 과정이 진행되는 동안 텐션아암(38)도 힌지핀(38')을 중심으로 반시계방향의 회전을 하여 그 단부의 텐션포스트(38a)가 테이프(41)를 가이드롤러(32)에 밀착시키면서 적절한 텐션을 부여하게 되며, 슬랜트포스트 조립체(29)(29')가 로딩패스(30)(30')를 타고 이송되면서 테이프(42)를 헤드드럼(34)에 소정각으로 감아주어 녹화(재생)모드가 되는 것이다.In this state, when the drive motor continues to rotate to rotate the drive cam 20, the function plate 23 is further moved to the right, so that the connecting pin 24 is connected from the connecting groove 25a of the connecting lever 25. After exiting, the inclined surface 25b of the connecting lever 25 is parallel to the moving direction of the function plate 23, and at the same time, the pin 28 of the pullout lever 27 is an obstacle of the other end of the connecting lever 25. The contact portion 25c is brought into contact with the cam surface 25d so that the tape 42 is slightly separated from the voice control head 35, and the connecting lever 25 and the drawing lever 27 stop without further rotation. The tension arm 38 also rotates counterclockwise around the hinge pin 38 'during the process, and the tension post 38a at the end guides the tape 41. While in close contact with the roller 32 to give the appropriate tension, the slant force Assembly to which the (29) (29 ') a loading path 30, 30' riding on the predetermined given tape 42 to the head drum 34 is wound on each recording (reproducing) mode while transfer.

이와 같이 테이프(42)가 헤드드럼(34)에 감기어 녹화(재생)모드로 될 때에 테이프(42)의 위치는 텐션포스트(38a) 가이드롤러(32), 전폭소거헤드(33), 슬랜드포스트조립체(29), 헤드드럼(34), 슬랜트포스트조립체(29'), 음성소거헤드(35), 캡스턴축(36)과 핀치로울러(40), 가이드포스트(37)의 경로가 되어 테이프(42)에 기록된 프로그램을 녹화 또는 재생을 할 수 있게되는 것이다. 이상에서 상술한 바와 같은 본 고안은 테이프를 고속으로 주행시키면서 테이프의 소정위치를 찾아내는 고속탐사용 테이프가이드장치에 있어서, 펑션플레이트에 연동되는 두 개의 레버를 이용하여 카세트로부터 인출한 테이프를 음성제어헤드에 접촉시켜줄 수 있게 함으로써 녹화재생모드에서 음성제어헤드로 테이프에 기록해둔 신호를 고속주행모드에서 다시 음성제어헤드로 찾아 낼 수 있도록 하여 신호기록부와 검출부를 동일하게 할 수 있게 되므로 테이프의 정확한 위치를 찾아낼 수 있게 되는 효과를 갖게 된다.In this manner, when the tape 42 is wound on the head drum 34 to be in the recording (playback) mode, the position of the tape 42 is the tension post 38a, the guide roller 32, the full width erasing head 33, and the sled. The post assembly 29, the head drum 34, the slant post assembly 29 ', the voice muting head 35, the capstan shaft 36 and the pinch roller 40, the guide post 37, the tape The program recorded in 42 can be recorded or played back. The present invention as described above, in the high-speed exploration tape guide device for finding a predetermined position of the tape while running the tape at a high speed, using the two levers linked to the function plate, the tape drawn from the cassette to the voice control head The signal recording unit and the detection unit can be made identical by detecting the signal recorded on the tape by the voice control head in the recording / playback mode in the high-speed driving mode. It has the effect of being able to find it.
