본 고안은 C. D 체인저의 드라이브 유닛(Drive Unit)승강장치에 관한 것으로 상세하게 복수 C. D 체인저의 회전원반에서 선택된 연주 C. D를 픽업장치로부터 연주되도록 하기 위하여 픽업장치를 승강되도록 하는 드라이브 유닛 승강장치에 관한 것이다.The present invention relates to a drive unit lifting device of a C. D changer, and a drive for lifting the pick-up device to make the selected device C. D play from the pick-up device. It relates to a unit hoisting device.
종래에는 본 고안 출원인에 의하여 선출원된 1989년 실용신안등록출원 제20210호로 제안하였던 승강장치가 알려져 있었다.Conventionally, a lifting device proposed in 1989 Utility Model Registration Application No. 20210 filed by the applicant of the present invention has been known.
이 장치는 기어드럼 상면의 캠의 높낮이에 따라 브라켓의 안내레버가 승강되고, 동시에 상승이나 하강이 종료되는 순간 스토퍼가 캠장치의 내측 캠홈을 따라 안내되게 하며, 전체적인 구동은 기어드럼의 연부에 형성된 기어를 다른 기어로서 구동되게 하여서 되고 이 기어드럼은 다시 C. D가 재치된 원반을 회동시키는 기어를 구성하며, 또한 각 제어회로와의 작동을 위하여 마이크로 스위치가 다시 기어드럼에 구성된 접촉자에 접촉구성되어 있다. 따라서, 전체적인 기어드럼의 구조가 복잡한 다중기어 장치로 구성되어 고장이 빈번할 뿐 아니라 일부구조의 고장발생시 전체가 작동정지되어 고장시의 응급처치가 복잡하고, 고장의 정도가 깊어지는 등의 문제점이 있었다.The device raises and lowers the guide lever of the bracket according to the height of the cam on the upper surface of the gear drum, and at the same time the stopper is guided along the inner cam groove of the cam device at the end of the rising or lowering, and the overall driving is formed at the edge of the gear drum. The gear drum is driven by another gear, which in turn constitutes a gear that rotates the disc on which the CD is placed, and the microswitch again contacts the contacts configured on the gear drum for operation with each control circuit. It is. Therefore, the structure of the overall gear drum is composed of a multi-gear device with a complicated structure, so that there are problems such as frequent failures, and the entire operation is stopped when some structures fail, resulting in complicated first aid in case of failure and deepening of the failure. .
본 고안은 이와 같은 다중기어 장치로된 기능의 복잡화를 피하고, 각 기능별로 작동이 수행될 수 있도록 하기 위하여 드라이브 유닛이 승강되는 단위장치를 구성하는 데에 그 목적이 있다.The object of the present invention is to construct a unit device in which the drive unit is lifted to avoid the complexity of the functions of the multi-gear device and to allow the operation to be performed for each function.
이와 같은 목적을 달성하기 위하여 본 고안은 픽업장치가 구성된 드라이브 유닛베이스의 안내레버를 승강시키기 위하여 받침판 위에 회동각도를 제한하는 반원돌출부를 저면에 구성하고 외주면을 따라 캠홈과 휠기어를 주벽에 구성하며, 이와 같은 캠의 휠기어에 접동되게 별도로 워엄기어를 구성하되 모터에 의하여 벨트로 구동되게 하며, 상기 캠의 저면에서 각도회동을 제한함과 아울러, 각도를 검출하는 각도제한 장치를 구성하므로, 회동각도의 검출이 용이할 뿐 아니라 단위장치화를 할 수 있는 특징이 있다.In order to achieve the above object, the present invention comprises a semicircular protrusion on the bottom plate to limit the angle of rotation on the base plate to raise and lower the guide lever of the drive unit base having the pick-up device, and the cam groove and the wheel gear on the outer wall. The worm gear is configured to be slid to the wheel gear of the cam, but is driven by the belt by the motor, and the angle limiting device detects the angle and limits the angle rotation at the bottom of the cam. Not only can the angle be easily detected, but it can be unitized.
첨부도면에 의거 상세히 설명하면 다음과 같다.According to the accompanying drawings in detail as follows.
본 고안은 받침판(6)위에 스토퍼(31)를 축지함과 아울러 검출단자(32)를 갖는 각도제한 및 검출장치(3)를 구성하고, 이 장치의 스토퍼(31)가 작동되는 구간내에 위치되게 캠홈(21), 휠기어(22) 및 반원돌출부(23)를 구성한 기어드럼(2)을 입설하고, 이 기어드럼(2)의 기어(22)에 접설되게 워엄기어(4)를 구성하며, 이 워엄기어(4)와 모터(5)는 그 축(51), (41)의 풀리(42)(52)에 벨트(53)를 걸어 전동(轉動)되게 한다.The present invention constitutes an angle limiting and detecting device 3 having a detecting terminal 32 and a stopper 31 on the supporting plate 6, and the stopper 31 of the device is positioned within the operating region. The gear drum 2 including the cam groove 21, the wheel gear 22, and the semicircular protrusion 23 is entered, and the worm gear 4 is configured to be connected to the gear 22 of the gear drum 2, The worm gear 4 and the motor 5 engage the belt 53 on the pulleys 42 and 52 of the shafts 51 and 41 so as to be electrically driven.
미설명 부호 1은 드라이브 유닛베이스이고, 10은 드라이브 유닛이고, 11은 안내레버이고, 7은 회전원반이고, 100은 C. D 체인저이고, 101은 트레이이다.Reference numeral 1 is a drive unit base, 10 is a drive unit, 11 is a guide lever, 7 is a rotating disc, 100 is a CD changer, and 101 is a tray.
이와 같은 구성된 본 고안은 조립상태는 제3도이고, 조립후의 작동 구조는 제2도에서 보는 바와 같이 드라이브 유닛(10)을 안치한 드라이브 유닛베이스(1)까지이다.In this configuration, the present invention is assembled as shown in FIG. 3, and the assembling operation structure is as far as the drive unit base 1 in which the drive unit 10 is placed, as shown in FIG.
본 고안은 복수 C. D가 재치된 루우렛(Roulette)에서 선택된 C. D가 회전되어 정지되는 순간부터 작동되는 것으로 짧은 시간동안 모터(5)가 구동되어 드라이브 유닛베이스(1)를 상승시킨다. 제4도에서 보여주는 바와 같이 기어드럼(2)의 휠기어(22)에 접설된 워엄기어(4)의 화동으로 기어드럼(2)이 회전되므로 캠홈(21)에 위치한 안내레버(11)를 상승시키게 되는 것이며, 상승이 완료되면 검출장치(3)의 스토퍼(31)가 반원돌출부(23)에서 밀려 상승됨을 신호하게 되어 모터(5)의 구동을 정지시킨다.The present invention operates from the moment when the selected C. D is rotated and stopped in a roulette in which a plurality of C. D are placed, and the motor 5 is driven for a short time to raise the drive unit base 1. As shown in FIG. 4, since the gear drum 2 is rotated by the hwadong gear 4 of the worm gear 4 attached to the wheel gear 22 of the gear drum 2, the guide lever 11 positioned in the cam groove 21 is raised. When the ascent is completed, the stopper 31 of the detection device 3 is pushed by the semi-circular protrusion 23 to signal the rise, thereby stopping the driving of the motor 5.
이후에는 소정의 C. D체인저 제어회로에서 드라이브 유닛(10)에 안치된 픽업장치의 재치원반에 의하여 C. D를 회전시켜 연주를 하게된다.Subsequently, C. D is rotated by the mounting disc of the pickup device placed in the drive unit 10 in a predetermined C. D changer control circuit to perform the performance.
이와 같은 본 고안은 역전이 방지되는 워엄기어를 채용함으로써 외부의 충격등에 의하여 역전될 수 있는 소자를 없애므로 동작의 안정성을 기할 수 있었으며 감속비가 큰 워엄기어로 인하여 종래의 다단기어장치가 갖는 결점을 개선케 되는 것으로 드라이브 유닛 승강장치 만의 단위회로서 조립구조를 간단화할 수 있게 되었으며, 종래장치보다 부품수를 줄일 수 있으며, 고장율이 개선되는 효과도 있다.The present invention eliminates the elements that can be reversed by external shocks by adopting a worm gear that prevents reversal, thereby ensuring stability of the operation, and the drawback of the conventional multi-stage gear device due to the worm gear having a large reduction ratio. It is possible to simplify the assembly structure as a unit unit only drive unit lifting device, and to reduce the number of parts than the conventional device, there is also an effect that the failure rate is improved.
