본 고안은 레코드 플레이어의 톤암 복귀장치에 관한 것으로 플레이가 시작되면 톤암이 음반으로 이동되었다가 플레이가 끝나면 다시 원위치로 복귀되도록 하기 위하여 레코드 플레이어의 플래터 회전축기어에 캠기어를 맞물려 그 저면에 톤암이 음반 위치로만 이동될 수 있도록 하는 한개의 캠을 돌설한 공지의 장치에 톤암의 복귀를 행할 수 있도록 하는 또다른 캠을 공지의 캠 바깥쪽으로 돌설하고 그 내측에는 버튼에 연결된 레버에 의해 유동되는 작동편을 축설하여 톤암이동판의 접촉돌기가 크고 작은 캠으로 구분 접촉되게 함으로써 손쉽게 톤암 복귀동작을 행할 수 있게한 것이다.The present invention relates to the tone arm return device of the record player. To play the tone arm on the record player when the play begins, the tone arm moves to the record and then returns to its original position. Another cam which allows the return of the tone arm to a known device protruding from one cam which can only be moved to a position is provided so that the cam is protruded out of the known cam and an actuating piece which is flown by a lever connected to the button is located therein. It is possible to easily perform the tone arm return operation by making the contact projection of the tone arm moving plate separated into large and small cams.

종래의 레코드 플레이어에 있어서 톤암의 이동장치는 플레터 회전축기어에 맞물려 회전하는 캠기어 저면에 톤암을 음반위치로 이동되도록 하는 한개의 캠만을 형성하였으므로 톤암이 음반상으로 이동되는 작동박에 행할 수 없는 반자동 장치가 알려지고 있으나 이와 같은 장치는 플레이가 끝나면 일일이 손으로 톤암을 들어 원위치시켜야 함으로써 번거로운 문제점이 있었던 것이다.In the conventional record player, the tone arm moving device is formed on the bottom of the rotating cam gear by engaging the platter rotary shaft gear so that only one cam is formed to move the tone arm to the record position. Although the device is known, such a device had a troublesome problem of having to reposition the tonearm by hand after play.

또한 톤암의 왕복동작이 전자동으로 이루워지게 하는 장치가 알려지고 있으나, 이들은 구조가 매우 복잡할 뿐만 아니라 고장율이 높고 생산원가가 높게 되는 결점이 있었던 것이다.In addition, there is a known device that allows the reciprocating operation of the tonearm to be fully automatic, but they are not only complicated in structure, but also have a high failure rate and high production cost.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is devised to solve the conventional problems as described above with reference to the accompanying drawings in detail as follows.

레코드 플레이어의 플레터 회전축기어와 맞물려 회전되는 캠기어(1)의 저면에 톤암(2)를 음반위로 이동시키기 위해 내면을 습동면(3')로 하는 작은캠(3)을 일체로 돌설하고 상기 습동면(3')에는 톤암이동판(4)의 접촉돌기(4')를 접촉시켜서된 것에 있어서 작은캠(3)의 바깥쪽에는 내면을 습동면(5')로 하는 큰캠(5)를 돌설하되 큰캠(5)의 내측에는 일단에 돌출봉(6')가 돌설된 작동편(6)을 축설하며 몸체내부에는 돌출봉(6')를 선택적으로 밀어주는 레버(7)을 설치하여서 된 것이다.In order to move the tone arm 2 to the phonogram on the bottom of the cam gear 1 which is rotated in engagement with the platter rotating shaft gear of the record player, the small cam 3 having the inner surface as the sliding surface 3 'is integrally formed and the wet On the outer surface of the small cam 3, the large cam 5 which has an inner surface as the sliding surface 5 'is formed by contacting the contact surface 4' of the tone arm moving plate 4 with the copper surface 3 '. However, the inner side of the large cam (5) to the end of the working piece (6) protruding projections (6 ') protruding at the end, and the inside of the body to install a lever (7) to selectively push the projection bar (6') .

도면중 미설명부호 8은 톤암이동판(4)에 설치된 회전돌편, 9는 톤암(2)와 동일축으로 고정된 회동판, 9'는 톤암회동판(9)상에 돌설된 걸림돌기, 10은 작동편(6)의 고정축 11은 캠기어(1)의 중심축을 보인 것이다.In the drawings, reference numeral 8 denotes a rotating stone piece installed on the tone arm moving plate 4, 9 a rotating plate fixed on the same axis as the tone arm 2, 9 'a protrusion formed on the tone arm rotating plate 9, 10 The fixed shaft 11 of the silver working piece 6 shows the central axis of the cam gear 1.

이와같이 된 본 고안의 작용효과를 설명하면 다음과 같다. 레코드 플레이어에 장착된 톤암을 이동시키기전의 작동편(6)의 위치는 제1도 a의 점선부와 같이큰캠에서 떨어져 있게 된다.When explaining the effect of the present invention made as follows. The position of the operation piece 6 before moving the tone arm mounted on the record player is separated from the large cam as shown by the dotted line in FIG.

이때 스타트 버튼을 누르게 되면 레버(7)은 작동편(6)의 돌출봉(6')를 밀어주게 되고 작동편(6)은 제1도 a의 실선부와 같이 큰캠(5)의 습동면(5')에 접촉되어 있게된다.At this time, when the start button is pressed, the lever 7 pushes the protruding rod 6 'of the operating piece 6, and the operating piece 6 moves along the sliding surface of the large cam 5 like the solid line of FIG. 5 ').

이 상태에서 음반의 음을 재생시키기 위해 플레터 회전축기어를 플레이 시키게 되면 제1도 b와 같이 이에 맞물린 캠기어(1)은 화살표 방향으로 회전하게 된다. 따라서 톤암이동판(4)의 접촉돌기(4')는 작동편(6)의 내연부와 접촉되어 작은캠(3)쪽으로 미끌어져 그 주벽에 접촉되며 이후 접촉돌기(4')와 작동편(6)의 접촉점이 고정축(10)을 지나면서 부터는 작동편(6)은 캠기어(1)의 중심축(11)쪽을 향하게 되고 큰캠(5)의 습동면(5')에서 떨어져 제1도 b와 같은 상태가 되는 것으로 이와같은 동작은 접촉돌기(4')가 작은캠(3)에 접촉되도록 하는 장치이며 일단 접촉돌기(4')작동편(6)을 벗어나면 공지의 톤암 이동동작이 이루어지는 것으로 캠기어(1)이 계속 회전하게 됨에 따라 접촉돌기(4')는 작은캠(1)의 습동면(3')에 접촉되어 습동되는 것으로 캠기어(1)의 중심축(11)에서 점차 근접된 위치로 접촉될수록 톤암이동판(4)는 캠기어(1)의 중심축(11)쪽으로 이동하게 된다.In this state, when the platter rotating shaft gear is played in order to reproduce the sound of the record, the cam gear 1 engaged with it as shown in FIG. 1 b rotates in the direction of the arrow. Therefore, the contact protrusion 4 'of the tone arm moving plate 4 is in contact with the inner edge of the operating piece 6 and slides toward the small cam 3 to contact the main wall thereof, and then the contact protrusion 4' and the operating piece ( Since the contact point of 6) passes through the fixed shaft 10, the operating piece 6 faces the central axis 11 of the cam gear 1 and is separated from the sliding surface 5 'of the large cam 5 by the first. As shown in FIG. 2B, the operation is such that the contact protrusion 4 'is brought into contact with the small cam 3, and once the contact protrusion 4' is moved out of the operation piece 6, the known tone arm moving operation is performed. As the cam gear 1 is continuously rotated, the contact protrusion 4 'is in contact with the sliding surface 3' of the small cam 1 and slides so that the center shaft 11 of the cam gear 1 is moved. As the tone arm moving plate (4) is moved toward the central axis (11) of the cam gear (1) as it is brought into close proximity to the position.

따라서 회전돌편(8)이 톤암회동편(9)의 걸림돌기(9')를 밀어주게 되지만 동일죽으로 고정된 톤암(2)는 톤암 고정대에 재치된 상태이기 때문에 유동없이 고정된 상태로 있게 된다.Therefore, the rotary stone piece 8 pushes the locking projection 9 'of the tone arm rotating piece 9, but the tone arm 2 fixed with the same porcelain is placed on the tone arm holder so that it remains fixed without flow. .

이와같은 상태는 캠기어(1)의 중심축(11)과 가장 근접된 위치인 a지점에 접촉돌기(4')가 위치되었을 때 톤암이동판(4)의 회전돌편(8)은 제1도 c의 점선부와 같이 시계바늘 방향으로 회전하게 되고, 접촉돌기(4')가 a지점을 벗어나는 위치에 있게 되면서 부터는 톤암이동판(4)는 캠기어(1)의 중심축(11)외측으로 이동하게 된다.In this state, when the contact protrusion 4 'is positioned at the point a, which is the position closest to the central axis 11 of the cam gear 1, the rotary protrusion 8 of the tone arm moving plate 4 is shown in FIG. As shown by the dotted line part of c, it rotates in the clockwise direction, and the tone arm moving plate 4 moves outward from the central axis 11 of the cam gear 1 from the point where the contact protrusion 4 'is in the position beyond the point a. Will move.

따라서 회전돌편(8)이 걸림돌기(9')를 걸고 회전하게 되므로 톤암(2)는 응반쪽으로 이동하게 된다. 결국 접촉돌기(4')가 제1도의 a와 같은 상태로 복귀 되었을 때는 톤암(2)의 이동은 멈춤과 동시에 톤암(2)의 카드리지가 음반 연부위에 위치하게 되는 것이다.Therefore, the rotary arm 8 is rotated by hanging the engaging projection (9 '), the tone arm (2) is moved to the counterpart. As a result, when the contact protrusion 4 'is returned to the state as shown in a of FIG. 1, the movement of the tone arm 2 is stopped and the cartridge of the tone arm 2 is positioned at the edge of the record.

이상과 같은 공지의 톤암 이동동작이 이루어지면 이 싯점부터 음재생동작이 이루워지는 것이며, 플레이가 끝나고 톤암(2)가 복귀되는 동작은 캠기어(1)의 회전에 따라 접촉돌기(4')는 제1도 a의 위치 즉 처음 출발점에서, 제1도 b와 같이 습동면(5')에서 떨어져 있는 작동편(6)의 단부에 걸려 작은캠(3)쪽으로 진입할 수 없게 되며 작동편(6)의 단부에 걸려 작은캠(3)쪽으로 진입할 수 없게 되며 작동편(6)과 큰캠(5)의 습동면(5') 사이로 진입하게 되어 습동면(5')와 접촉하게 된다.If the known tone arm movement operation is made as described above, the sound reproduction operation is achieved from this point, and the operation of returning the tone arm 2 after the play is completed is performed by the contact projection 4 'according to the rotation of the cam gear 1. At the position of FIG. 1 a, i.e., at the first starting point, is caught by the end of the operating piece 6 which is separated from the sliding surface 5 'as shown in FIG. It is caught by the end of 6) can not enter the small cam (3) and enters between the sliding surface (5 ') of the operating piece (6) and the large cam (5) is in contact with the sliding surface (5').

그리고 습동면(5')와 캠기어(1)의 중심축(11)과 사이가 좁아지는 위치인 A지점에 접촉돌기(4')가 위치되었을때 톤암이동판(4)의 회전돌편(8)은 회동판(9)의 걸림돌기(9')와 맞닿은 상태가 된다.Then, when the contact projection 4 'is positioned at the point A, which is a position where the sliding surface 5' and the central axis 11 of the cam gear 1 become narrower, the rotating projection piece 8 of the tone arm moving plate 4 ) Is in contact with the locking projection 9 'of the rotating plate 9.

이 상태에서 캠기어(1)이 회전됨에 따라 톤암이동판(4)는 캠기어(1)의 중심축(11)을 항하여 이동되게 된다.In this state, as the cam gear 1 is rotated, the tone arm moving plate 4 is moved along the central axis 11 of the cam gear 1.

따라서 회전돌편(8)이 회동판(9)의 걸림돌기(9')를 걸고 회전하게 되어 톤암(2)를 복귀시키게 되는 것으로 중심축(11)과 가장 근접한 위치인 A'지점에 접촉돌기(4')가 위치된 때 회동판(9)의 이동이 멈춰지게 된다.Therefore, the rotating projection piece 8 is rotated by hanging the locking projection 9 'of the rotating plate 9 to return the tone arm 2, and the contact projection (A') which is the position closest to the central axis 11 ( When 4 ') is positioned, the movement of the rotating plate 9 is stopped.

따라서 톤암(2)도 A'지점에서 멈춰지게 되며, 이 A'지점이 바로 톤암(2)의 복귀가 끝나는 지점인 톤암 고정대와 일치하게 되는 것이다. 이렇게 되면 톤암(2)의 복귀동작이 끝나게 되는 것으로 A'지점이후 부터는 캠기어(1)의 중심축(11)과의 거리가 멀어지게 됨으로 톤암이동판(4)도 중심축(11)의 외측으로 이동되어 회전돌편(8)은 걸림돌기(9')에서 떨어지게 되고 톤암이동판(4)만 제1도 a와 같은 상태로 원위치되어 톤암(2)이동의 초기상태로 되는 것이다.Therefore, the tone arm 2 is also stopped at the point A ', and this point A' coincides with the tone arm holder, which is the point where the return of the tone arm 2 ends. In this case, the return motion of the tone arm 2 is ended, and the distance from the center axis 11 of the cam gear 1 becomes far from the point A ', so that the tone arm moving plate 4 is also outside the center axis 11. The rotating stone piece 8 is moved away from the locking projection 9 'and only the tone arm moving plate 4 is returned to its initial state as shown in FIG.

이와 같이 본 고안은 톤암의 일방향 이동만을 수행하는 캠외측에 톤암의 복귀운동을 수행하도록 외측캠과 작동편을 설치하여 레버로 작동되게 함으로써 매우 간단한 구조로써 제작이 용이하고 동작이 원만하게 이루어지는 잇점을 얻게 되는 것이다.As such, the present invention provides an advantage that the outer cam and the operating piece are installed on the outer side of the cam which performs only one-way movement of the tone arm, and are operated by levers to operate the lever.
