본 고안은 디스크 플레이어의 픽업(Pick up) 이송장치에 관한 것으로서, 더욱 상세하게는 콤팩트 디스크에 수록된 정보를 판독하는 광픽업의 안정된 이송과 작동성능을 향상시켜 주는 디스크 레이어의 픽업 이송장치에 관한 것이다.The present invention relates to a pick-up feeder of a disc player, and more particularly, to a pick-up feeder of a disc layer that improves stable transport and operation performance of an optical pickup for reading information contained in a compact disc. .
종래의 픽업이송장치 중에는 제1도에서 보는 바와 같이 픽업구조체(1)가 장착된 이송부재(2)의 일측면에는 이송축(3)이 관통 설치되고, 타측면에는 안내로드(4)가 관통 설치되어, 모터(5)가 구동되면 맞물려 설치된 어(3')(5')들이 연동되고 이에 따라 이송축(3)이 회전되므로 그 회전방향에 따라 이송부재(2)가 전·후방향으로 슬라이딩 된다.In the conventional pickup transport apparatus, as shown in FIG. 1, a feed shaft 3 is penetrated through one side of the transfer member 2 on which the pickup structure 1 is mounted, and a guide rod 4 penetrates through the other side. When the motor 5 is driven, the gears 3 'and 5' interlocked with each other are interlocked and the feed shaft 3 is rotated accordingly, so that the feed member 2 moves forward and backward in accordance with its rotational direction. It is sliding.
그러나, 상기의 장치는 이송축(3)의 회전력이 왕복운동으로 전환되어 이송부재(2)를 이송시켜 줄 때, 이송부재(2)의 일측면에 이송축(3)이 관통하게 부설된 안내너트부(2')에 회전력이 전달되어, 이 안내너트부에 의해 왕복운동으로 전환되게 한 것이므로 이송부재(2)의 일측면에 가해지는 힘이 반대측에 설치된 안내로드(4)에 모우먼트(Moment)를 발생시키는 작용을 한다.However, in the above apparatus, when the rotational force of the feed shaft 3 is converted into a reciprocating motion to transport the feed member 2, the guide is provided so that the feed shaft 3 penetrates on one side of the feed member 2. Since the rotational force is transmitted to the nut part 2 'and the guide nut part is converted into reciprocating motion, the force applied to one side of the conveying member 2 is applied to the guide rod 4 provided on the opposite side. Moment) acts to generate.
이렇게 되면, 회전력을 왕복운동으로 전환하여 주는 안내너트부(2')에 가해지는 힘과, 안내로드(4)에 결합되는 반대측으로 가해지는 힘이 서로 상이하게 된다.In this case, the force applied to the guide nut portion 2 'for converting the rotational force into the reciprocating motion and the force applied to the opposite side coupled to the guide rod 4 are different from each other.
이에 따라, 이송부재(2)의 슬라이딩 동작이 원활하지 못하게 되어 픽업의 이송성능이 저하되므로 정확한 판독이 불가능하게 되는 등의 문제점이 발생되었다.As a result, the sliding operation of the transfer member 2 is not smooth and the transfer performance of the pickup is lowered, thereby making it impossible to accurately read.
본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서, 그 목적은 픽업의 이송성능을 향상시켜 주는 디스크플레이어의 필업 이송장치를 제공하는 것이다.The present invention has been made in view of the above problems, and an object thereof is to provide a disk player fill-up transfer apparatus for improving the transfer performance of the pickup.
본 고안의 이러한 목적은, 픽업의 장착된 이송부재를 모터에 의해 회전되는 이송축에 나사결합된 안내너트부에 의해 왕복동작되게 하는 이송개념에서, 힘의 모우먼트에 의한 불안전한 이송동작을 방지하고 원활한 동력전달이 가능하도록 안내부재의 구조를 개선하여 정확한 슬라이딩 동작이 진행되게 한 것이다.This object of the present invention is to prevent the unsafe conveying operation by the moment of force in the conveying concept of allowing the pick-up conveying member of the pickup to be reciprocated by the guide nut screwed to the feed shaft rotated by the motor. And to improve the structure of the guide member to enable a smooth power transmission is to proceed the accurate sliding operation.
이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도 및 제3도는 본 고안의 실시예를 보인 것으로서, 도면부호중(10)은 판독기능을 가진 픽업구조체이며, 이 픽업구조체는 기기(도시하지 않았음) 상에서 슬라이딩 동작되는 이송부재(20)에 장착된다.2 and 3 show an embodiment of the present invention, in which reference numeral 10 denotes a pick-up structure having a reading function, and the pick-up structure is a transfer member 20 which is slidably operated on an apparatus (not shown). ) Is mounted.
상기 이송부재(20)의 일측에는 회전운동을 왕복운동으로 전환시켜 주는 나선부(31)가 외단에 형성된 안내너트(30)를 그 내단에 연장된 결착편(32)으로 착설되며, 이 결착편(32)은 탄성력을 갖게 형성된다.On one side of the conveying member 20 is installed a guide nut 30 formed on the outer end of the spiral nut 31 for converting the rotational movement into a reciprocating motion as a binding piece 32 extending at the inner end thereof. 32 is formed to have an elastic force.
그리고, 안내너트(30)가 착설되는 이송부재(20)의 일측전후에는 부싱(41)이 결합된 축수부(40)가 부설된다.And, before and after one side of the transfer member 20 in which the guide nut 30 is installed, the bearing 40 is coupled to the bushing 41 is installed.
또한, 안내너트(30)에 대향되는 이송부재(20)의 타측에는 안내홈(50)이 형성되며, 이 안내홈에는 이송부재(20)를 지지하는 지지부재(60)의 일단부가 결합 설치된다.In addition, a guide groove 50 is formed at the other side of the transfer member 20 opposite to the guide nut 30, and one end of the support member 60 supporting the transfer member 20 is coupled to the guide groove 30. .
한편, 안내너트(30)는 나선홈(71)이 형성된 이송축(70)에 결합되며, 이 이송축의 일단에 축착된 기어(72)는 모터(80)축에 축작된 기어(81)와 맞물려 연동된다.On the other hand, the guide nut 30 is coupled to the feed shaft 70 in which the spiral groove 71 is formed, and the gear 72 fixed to one end of the feed shaft is engaged with the gear 81 that is arranged on the shaft of the motor 80. Interlocked.
그리고, 상기 안내홈을 형성하여 주게 이송부재(20)의 타측편 하부에 착설하는 판재(51)는 탄성재질로 된다.In addition, the plate 51 to be installed on the lower side of the other side of the conveying member 20 to form the guide groove is made of an elastic material.
이와 같이 구성되는 본 고안은, 모터(80)의 구동으로 기어(72)(81)가 연동되면, 기어(72)가 축착된 이송축(70)이 제자리에서 회동하게 되므로, 이 축의 나선홈(71)에 나선부(31)가 맞물리게 나사결합된 안내너트(30)가 상기 이송축의 회전방향에 따라 전·후 왕복동작을 하게 된다.According to the present invention configured as described above, when the gears 72 and 81 are linked by the driving of the motor 80, the feed shaft 70 on which the gear 72 is condensed is rotated in place, so that the spiral groove of the shaft ( The guide nut 30 screwed with the spiral portion 31 engaged with the screw 31 is moved forward and backward according to the rotational direction of the feed shaft.
이렇게 되면, 상기 안내너트(30)가 착설된 이송부재(20)가 함께 동작되어 슬라이딩 된다.In this case, the conveying member 20 on which the guide nut 30 is installed is operated and slides together.
이때, 이송부재(20)는 지지부재(60)에 의해 지지된 상태로 슬라이딩 되는데, 이 지지부재는 안내홈(50) 내에서 충분한 유동거리를 갖게 되므로, 반대측으로부터 모우먼트가 발생될 경우에도 편심작용으로 인한 이송장애가 발생되지 않게 된다.At this time, the conveying member 20 is slid in a state supported by the supporting member 60, since the supporting member has a sufficient flow distance in the guide groove 50, even when the moment is generated from the opposite side The transfer failure due to the action is not generated.
또한, 안내호(50)의 구성요소인 판재(51)가 탄성재질로 되므로 이 판재가 이송부재(20)의 상하방향으로 발생되는 장력을 완충 또는 흡수하는 작용을 한다.In addition, since the plate 51 which is a component of the guide arc 50 is made of an elastic material, the plate serves to absorb or absorb the tension generated in the up and down direction of the transfer member 20.
그리고, 안내너트(30)의 전후에 위치한 축수부(40)에는 그 내부에 장착된 부싱(41)을 관통하게 이송축(70)이 결합되었기 때문에, 이 축은 부싱(41)의 내주면상에서 미끄럼동작되므로 동력이 전달되는 초기부터 이송부재(20)에 모우먼트가 방지된다.In addition, since the feed shaft 70 is coupled to the bearing portion 40 positioned before and after the guide nut 30 through the bushing 41 mounted therein, the shaft slides on the inner circumferential surface of the bushing 41. Therefore, the moment is prevented in the transfer member 20 from the initial power transmission.
또한, 이송부재(20)에 착설된 안내너트(30)의 결착편(32)도 탄성력을 가진 재질로 되므로, 안내홈(50)을 형성하는 판재(51)와 더불어 이송부재(20)에 상하방향으로 미치는 장력을 완화시켜주게 되어, 원활한 이송동작이 가능하게 되므로, 상기 이송부재에 장착되어 있는 픽업구조체(10)를 보다 정확히 이동시켜 주게되는 것이다.In addition, since the binding piece 32 of the guide nut 30 installed on the conveying member 20 is also made of a material having elastic force, the upper and lower portions of the conveying member 20 together with the plate member 51 forming the guide groove 50. The tension in the direction is relieved, so that a smooth conveying operation is possible, thereby more accurately moving the pick-up structure 10 mounted on the conveying member.
이와 같이 본 고안은, 픽업이 장착된 이송부재의 이송손실을 최소화함과 아울러 원활하게 이송되게 함으로써, 이송성능을 향상시켜 주는 효과가 있으며, 또 정확한 판독기능을 수행할 수 있게 하여 주는 장점이 있다.As such, the present invention minimizes the transfer loss of the transfer member on which the pickup is mounted and smoothly transfers the transfer performance, thereby improving the transfer performance and providing an accurate reading function. .
