본 고안은 자동반전 기능을 가진 테이프레코더에 있어서, 테이프의 주행방향에 따라헤드를 절환시킬수 있도록한 헤드절환장치에 관한 것이다.The present invention relates to a head switching device in which a tape recorder having an automatic reversing function can switch a head according to a running direction of a tape.
종래에도 테이프의 주행방향에 따라 헤드를 절환하는 절환장치가 안출된바 있었으나, 이는 헤드베이스에 반전캠에 의해서 작동되는 반전레버를 길게 설치하고 반전캠의 회동에 따라 반전레버가 회전하면서 헤드를 절환시키도록 되어 있기 때문에 반전레버의 길이가 길어져야만 했으며, 반전레버가 길어짐에 따라 헤드의 절환 범위가 넓게되고 따라서 절환스위치를 2개 설치 하여야만 하는 문제가 발생될 뿐만 아니라 반전레버의 동작범위가 크기 때문에 헤드절환 상태가 원활하고 정확하게 이루어지지 못하게 되는 등의 문제점이 있었다.Conventionally, a switching device for switching the head according to the driving direction of the tape has been conceived, but this is provided with a reversing lever operated by the reversing cam on the head base for a long time, and the reversing lever rotates according to the rotation of the reversing cam. Since the length of the inversion lever had to be long, the length of the inversion lever had to be long, and the range of switching of the head became wider. There was a problem that the head switching state is not made smoothly and accurately.
본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 작은 작동범위로서 헤드절환을 보다 정확하고 원활하게 행할수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been conceived in order to more accurately and smoothly change the head to a smaller operating range in view of the conventional problems as described above in detail based on the accompanying drawings as follows.
절환용 헤드(3)를 데크(1) 일방의 헤드베이스(2)에 설치하고 이의 일방에 캠롤러(5)를 가진 반전캠(4)과 구동기어(6)를 설치하며 헤드베이스(2)의 일방에 절환스위치(7)를 설치한 것에 있어서, 상기 반전캠(4)의 상부에 작동요부(9)를 형성한 작동편(8)을 이동가능하게 설치하되, 작동편(8)의 중앙에는 연결편(10)을, 양방에는 가이드공(11), (12)을 각각 형성하며 가이드공(12)의 일방에 요부(13)를 형성한다.The switching head 3 is installed on the head base 2 of the deck 1, and the reversing cam 4 having the cam rollers 5 and the drive gear 6 are installed on the head base 2 of the deck 1. In the changeover switch 7 provided on one side of the reversing cam 4, the operating piece 8 having the operation recess 9 formed on the upper portion of the reversing cam 4 is movable, but the center of the operating piece 8 is provided. In the connecting piece 10, the guide holes 11 and 12 are formed in both sides, and the recessed part 13 is formed in one of the guide holes 12, respectively.
상기 가이드공(11), (12)에는 데크(1)에 돌출형성된 핀(14)과 가이드편(15)이 각각 삽입설치되며, 상기 연결편(10)은 회동편(16)의 유설되고 회동편(16)의 타단은 헤드베이스(2)의 절곡편(201)에 유설되며 회동편(16)의 중앙에는 축(17)이 설치된다.The pins 14 and the guide pieces 15 protruding from the deck 1 are inserted into the guide holes 11 and 12, respectively, and the connecting piece 10 is installed at the rotating piece 16. The other end of 16 is flush with the bending piece 201 of the head base 2, and the shaft 17 is provided in the center of the rotation piece 16. As shown in FIG.
또한, 상기 헤드베이스(2)의 일방에는 한쌍의 돌출편(202)이 형성되어 이들사이에 상기 절환스위치(7)가 위치되도록 구성되어 있다.In addition, a pair of protruding pieces 202 are formed on one side of the head base 2 so that the switching switch 7 is positioned between them.
이상과 같이 구성된 본 고안은 제1도에서와 같이 반전캠(4)과 캠롤러(5)가 도면상 좌측에 위치하게되면 이에 접면된 작동편(8)의 작동요부(9)가 좌측에 위치하게되고 데크(1)의 헤드베이스(2)는 우측으로 이동된 상태로 있게되며 헤드베이스(2)의 돌출편(202)사이에 있는 절환스위치(7)와 헤드(3)는 테이프의 정상주행시 이의 기록을 재생할수 있는 상태로 있게 된다.According to the present invention configured as described above, as shown in FIG. 1, when the inverting cam 4 and the cam roller 5 are positioned on the left side of the drawing, the operation recess 9 of the operating piece 8 which is folded on the left side is positioned on the left side. The head base 2 of the deck 1 is left to move to the right and the changeover switch 7 and the head 3 between the protruding pieces 202 of the head base 2 during the normal running of the tape This record can be reproduced.
이러한 상태에서 테이프가 정상주행을 완료하고 반전 주행을 하려고 할때는 구동기어(6)가 반전캠(4)을 회전시키게되며 반전캠(4)의 회동에 따라 이의 캠롤러(5)가 함께 회전하여 작동요부(9)를 도면상 우측으로 이동시키게 되고, 작동요부(9)의 이동으로 작동편(8)은 가이드공(11), (12)의 핀(14)과 가이드편(15)의 안내를 받으면서 도면상 우측으로 이동된다.In this state, when the tape completes the normal driving and tries to reverse driving, the driving gear 6 rotates the reverse cam 4, and the cam rollers 5 rotate together with the rotation of the reverse cam 4 to operate. The recess 9 is moved to the right side in the drawing, and the movement of the actuating recess 9 causes the actuating piece 8 to guide the pins 14 and the guide piece 15 of the guide holes 11 and 12. It is moved to the right on the drawing.
이때, 작동편(8)이 구동기어(6)의 상부로 이동되지만, 작동편(8)의 일방에 요부(13)가 형성되어 있어 작동편(8)이 구동기어(6)에 걸리지는 않는다.At this time, the operation piece 8 is moved to the upper portion of the drive gear 6, but the recessed portion 13 is formed on one side of the operation piece 8, so that the operation piece 8 is not caught by the drive gear 6. .
한편, 작동편(8)이 우측으로 이동함에 따라 이의 연결편(10)이 회동편(16)의 일단을 밀게되는데, 회동편(16)이 축(17)을 중심으로 회동하기 때문에 회동편(16)은 시계방향으로 회전되고 이의 타단이 헤드베이스(2)의 절곡편(201)을 도면상 좌측으로 밀게된다.On the other hand, as the operating piece 8 moves to the right, the connecting piece 10 thereof pushes one end of the rotating piece 16, and the rotating piece 16 rotates about the axis 17, so that the rotating piece 16 ) Is rotated clockwise and the other end thereof pushes the bending piece 201 of the head base 2 to the left in the drawing.
절곡편(201)이 좌측으로 밀려지면 이와 일체로된 헤드 베이스(2)가 데크(1)에서 좌측으로 이동되고 이의 돌출편(202)이 절환스위치(7)를 반대로 작동시켜 헤드(3)를 절환시키며 이는 제2도와 같이 된다.When the bent piece 201 is pushed to the left, the head base 2 integrally therewith is moved from the deck 1 to the left side, and the protruding piece 202 thereof operates the changeover switch 7 in reverse to open the head 3. The switch is made as shown in FIG.
상기와 같은 상태로 절환한 후에 테이프가 반전주행을 하게되고 테이프의 반대면에 기록된 신호가 재생되는 것이다. 또 반전주행후 상기의 역동작으로 각 부품이 제1도와 같이 역동작되며 역동작에 따라 정상주행 위치로 다시 복귀되는 것이다.After switching to the above state, the tape is reversed and the signal recorded on the opposite side of the tape is reproduced. In addition, after the reverse driving, the parts are reversed as shown in FIG. 1 by the reverse operation, and return to the normal driving position according to the reverse operation.
이상과 같은 본 고안은 반전캠의 동작에 따라 작동편이 수평이동되고 이의 이동에 따라 짧은 거리와 작은 회전각으로 헤드를 절환시킬 수 있으며 이에따라 절환시의 동작을 작게하면서도 정확하게 할수 있고 헤드의 절환을 원활하고 신속하게 할수 있어 동작의 안전성을 기대할수 있게되는 점등의 특징을 지닌 것이다.According to the present invention, the moving piece is horizontally moved according to the operation of the reversing cam, and the head can be switched at a short distance and a small rotation angle according to the movement of the reversing cam. It can be done quickly and can be expected to have the safety of operation is characterized by the lighting.
