Description

테이프 레코더의 핀치롤러 가압장치Pinch roller presser of tape recorder

본 고안은 테이프 레코더의 핀치롤러 가압장치에 대한 것으로서, 더 상세하게는 테이프를 가압이송하는 핀치롤러가 캡스턴과 균일하게 가압될 수 있도록 개선된 테이프 레코더의 핀치롤러 가압장치에 관한 것이다.The present invention relates to a pinch roller pressing device of a tape recorder, and more particularly, to a pinch roller pressing device of an improved tape recorder so that the pinch roller pressing and feeding the tape can be uniformly pressed with the capstan.

일반적으로 테이프 레코더는 테이프 카세트로부터 테이프를 인출시키고 인출된 테이프를 복수의 가이드롤러에 안내하여서 회전드럼과 소정의 상대속도로 주행시키는 구조를 가지며, 이 주행되는 테이프에 자기헤드가 경사상으로 스캐닝하여서 기록/재생하도록 하는 자기/기록재생기구이다. 이러한 테이프 레코더에 있어서 테이프는 통상 릴 테이블의 회전과 더불어 캡스턴 모터축과 핀치롤러의 가압으로 이송된다. 이 때 테이프의 손상방지를 위해서는 캡스턴과 핀치롤러의 균일한 가압력이 요구된다.In general, a tape recorder has a structure that draws a tape from a tape cassette and guides the drawn tape to a plurality of guide rollers to travel at a rotational drum and at a predetermined relative speed. A magnetic / recording and reproducing mechanism for recording / reproducing. In such a tape recorder, the tape is usually conveyed by the pressure of the capstan motor shaft and the pinch roller as well as the rotation of the reel table. At this time, in order to prevent the tape from being damaged, a uniform pressing force between the capstan and the pinch roller is required.

그런데, 종래의 핀치롤러 가압장치에 있어서는, 제1a도에 도시된 바와 같이, 캠핀(22)에 가해지는 힘(F)의 수직성분만이 상기 핀치롤러(21)가 캡스턴(23)에 가압되는 가압력(P)으로 작용하기 때문에 가압 효율이 저하되게 된다.By the way, in the conventional pinch roller pressurizing device, as shown in FIG. 1A, only the vertical component of the force F applied to the cam pin 22 is pressed by the pinch roller 21 to the capstan 23. Since it acts as the pressing force P, the pressurization efficiency falls.

또한 제1b도에 도시된 바와 같이, 구동력(F)을 받는 캠핀(22)은 상기 핀치아암(20)의 하부에 위치되고, 상기 핀치롤러(21)는 그 핀치아암(20)의 상부에 위치되어 있기 때문에, 실제로 작동시에 핀치롤러(21)가 위쪽으로 회전되려고 하는 회전모멘트(M)가 작용하게 된다.In addition, as shown in Figure 1b, the cam pin 22 receives the driving force (F) is located below the pinch arm 20, the pinch roller 21 is located above the pinch arm 20 Since the pinch roller 21 is actually rotated upward, the rotation moment M is acted upon.

이는 불균일한 가압력을 발생시켜 가압되는 테이프를 부상시킴으로써 테이프에 손상을 주기 쉽게 되는 문제점이 있다.This causes a problem in that the tape is easily damaged by generating a non-uniform pressing force and causing the tape to be pressurized.

따라서 본 고안은 상기의 문제점을 해결하기 위해 창출된 것으로서, 핀치롤러의 회전모멘트가 제거되고 가압 효율이 향상된 테이프 레코더의 핀치롤러 가압장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a pinch roller pressing device of a tape recorder in which the rotation moment of the pinch roller is removed and the pressing efficiency is improved.

상기의 목적을 달성하기 위한 본 고안은, 캡스턴에 테이프를 밀착시키도록 이동하여 가압되며 그 캡스턴과 함께 회전되어서 그 사이의 테이프를 이동시키는 핀치롤러를 갖는 테이프 레코더의 핀치롤러 가압장치에 있어서, 상기 핀치롤러가 회전가능하게 지지되어 있고 그 핀치롤러가 캡스턴으로 이동될 수 있게 피봇지지된 제1아암부재와, 상기한 제1아암부재와 스프링으로 연결되어 그 제1아암부재를 탄력적으로 당길 수 있게 피봇지지된 제2아암부재와, 상기한 제2아암부재를 회전이동되게 연동시키는 연동수단이 구비되어 상기한 가압레버의 회전이동에 따라서 상기한 핀치아암이 회전이동되고 그 사이에서 인장되는 스프링에 의해 상기 핀치롤러가 가압되도록 된 것을 특징으로 한다.In the present invention for achieving the above object, in the pinch roller pressing device of the tape recorder having a pinch roller which is moved to press the tape to the capstan in close contact with the capstan is rotated to move the tape therebetween, A first arm member pivotally supported so that the pinch roller can be moved to the capstan, and a spring connected to the first arm member to resiliently pull the first arm member. A pivot-supported second arm member and an interlocking means for interlocking the second arm member in rotational movement are provided so that the pinch arm is rotated and tensioned therebetween in accordance with the rotational movement of the pressure lever. It is characterized in that the pinch roller is pressed by.

여기서 상기한 연동수단은, 상기 제2아암부재에 설치된 캠핀과, 이 캠핀이 삽입되는 캠그루우브를 갖는 캠기어부재와, 이 캠기어부재를 구동하는 동력을 발생하는 모터를 구비하여 이루어진다.The interlocking means includes a cam pin provided on the second arm member, a cam gear member having a cam groove into which the cam pin is inserted, and a motor for generating power for driving the cam gear member.

또한 상기한 제1아암부재와 제2아암부재가 동일축상에 피봇지지 되는 것이 바람직하다.It is also preferable that the first arm member and the second arm member are pivotally supported on the same axis.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도 및 제3도는 본 고안에 따른 테이프 레코더의 핀치롤러 가압장치를 나타낸다.2 and 3 show the pinch roller pressing device of the tape recorder according to the present invention.

먼저 제2도를 참조하면, 데크(100)에 마련된 회동축(50)에 제1아암부재(30) 및 제2아암부재(40)가 동축상으로 각각 회동가능하게 피봇지지되어 설치된다.First, referring to FIG. 2, the first arm member 30 and the second arm member 40 are pivotally rotatably installed on the pivot shaft 50 provided on the deck 100 in a coaxial manner.

여기서 상기 제1아암부재(30)는, 일단에 상기 회동축(50)과 결합되는 제1관통공(33)이 형성되어 있고, 타단에는 핀치롤러(31)가 회전가능하게 설치되어 있다.Here, the first arm member 30 has a first through hole 33 coupled to the pivot shaft 50 at one end thereof, and a pinch roller 31 is rotatably installed at the other end thereof.

그리고 상기 제2아암부재(40)에는 상기 회동축(50)과 결합되는 제2관통공(43)이 형성되어 있으며, 상기 제1아암부재(30)의 하부에 위치되도록 동축상에 결합된다. 또한 상기 제2아암부재(40)의 저면에는 모터(90)에 의해 회전되는 캠기어부재(80)에 연동되는 캠핀(41)이 마련되어 있다. 이 캠핀(41)이 상기 캠기어부재(80)에 형성된 캠그루우브(81)에 삽입되어 슬라이딩됨으로써 연동되게 된다.In addition, the second arm member 40 is formed with a second through hole 43 coupled with the pivot shaft 50 and is coaxially coupled to be positioned below the first arm member 30. In addition, the bottom of the second arm member 40 is provided with a cam pin 41 which is linked to the cam gear member 80 rotated by the motor 90. The cam pin 41 is inserted into the cam groove 81 formed on the cam gear member 80 to slide.

그리고 상기 제1, 2아암부재(30, 40)에는 각각 걸림턱(32, 42)이 마련되어 있고, 이 걸림턱(32, 42)에 스프링부재(70)가 결합됨으로써, 상기 제1, 2 아암부재(30, 40)를 상호 탄성바이어스되게 연결하게 된다.The first and second arm members 30 and 40 are provided with locking jaws 32 and 42, respectively, and the spring members 70 are coupled to the locking jaws 32 and 42, thereby providing the first and second arms. The members 30 and 40 are elastically biased to each other.

이와 같은 구조에 있어서, 제3도에 도시된 바와 같이 상기 캠핀(41)에 A방향으로 구동력이 가해지면, 상기 제2아암부재(40)가 상기 회동축(50)을 중심으로하여 B방향으로 회전하게 된다. 이 때 상기 걸림턱(32, 42)에 결합되어 있는 스프링부재(70)가 그 탄성력으로 상기 제1아암부재(30)를 C방향으로 끌어당기게 된다.In this structure, as shown in FIG. 3, when a driving force is applied to the cam pin 41 in the A direction, the second arm member 40 moves in the B direction about the pivot shaft 50. Will rotate. At this time, the spring member 70 coupled to the locking jaws 32 and 42 pulls the first arm member 30 in the C direction by the elastic force.

이에 따라서 상기 제1아암부재(30)가 상기 회동축(50)을 중심으로 D방향으로 회전하여, 상기 핀치롤러(31)가 캡스턴(60)에 가압되게 된다.Accordingly, the first arm member 30 is rotated in the D direction about the rotation shaft 50, so that the pinch roller 31 is pressed against the capstan 60.

그러므로, 상기 캠핀(41)에 가해진 구동력이 상기 제2아암부재 (40)를 통해 스프링부재(70)의 탄성력으로서 제1아암부재(30)로 전달되며, 그 전달되는 힘은 상기 제2아암부재(32)와 동일한 수평면에서 전달되기 때문에, 전술한 바와 같은 핀치롤러(31)의 회전모멘트(도 1;M)는 없어지게 된다.Therefore, the driving force applied to the cam pin 41 is transmitted to the first arm member 30 as the elastic force of the spring member 70 through the second arm member 40, and the transmitted force is transmitted to the second arm member. Since it is transmitted in the same horizontal plane as 32, the rotation moment (Fig. 1; M) of the pinch roller 31 as described above is lost.

또한, 이와 같은 구조에 있어서는, 가해지는 힘의 수직 또는 수평성분과 같은 일부분만이 전달되는 것이 아니라, 전체적인 힘이 모두 전달되게 됨으로써, 핀치롤러의 가압력이 향상되게 된다.In addition, in such a structure, not only a portion of the applied force, such as a vertical or horizontal component, is transmitted, but the entire force is transmitted, whereby the pressing force of the pinch roller is improved.
