Description
본 발명은, 비디오테이프레코더 등의 자기기록재생장치에 관한 것이다.The present invention relates to a magnetic recording / playback apparatus such as a video tape recorder.
종래의 비디오테이프레코더(이하 “VTR”이라 칭함)에 대해서, 도면을 참조하면서 설명한다.A conventional video tape recorder (hereinafter referred to as "VTR") will be described with reference to the drawings.
제3도는, 종래의 실시예에 있어서의 VTR의 카세트장착장치의 측면도를 표시한다.3 shows a side view of the cassette mounting apparatus of the VTR in the conventional embodiment.
VTR의 내림으로부터 삽입된 카세트테이프는 카세트홀더에 의해서 유지되고, 이 카세트 홀더는 좌우에 있는 측판(side plate)(14)의 홈부(15)와, 이 측판(14)에 회동가능하게 걸림된 회동부재(이하, “와이퍼암”이라 칭함)(16)에 의해서 유지되며, 로딩모터 등의 구동원으로부터 전달된 회전이 와이퍼암(16)에 전달되어, 와이퍼암(16)이 회동함으로써 카세트홀더를 홈부(15)를 따라서 이동시켜 카세트테이프를 VTR메카니즘부의 정위치에 배치시킨다.The cassette tape inserted from the lowering of the VTR is held by the cassette holder, and the cassette holder is pivotally locked to the groove 15 of the side plate 14 on the left and right sides and the side plate 14. Retained by a member (hereinafter referred to as "wiper arm") 16, a rotation transmitted from a driving source such as a loading motor is transmitted to the wiper arm 16, and the wiper arm 16 rotates so that the cassette holder is grooved. Moving along (15), the cassette tape is placed in position in the VTR mechanism portion.
그러나 상기 종래의 구성에서는, 카세트테이프의 내림으로부터의 튀어나옴량을 증대시키기 위하여, 수평이동거리를 길게하려면, 와이퍼암의 암부를 길게할 필요가 있으며, 이에 의해 프런트로딩기구의 높이가 높아진다고하는 문제점을 가지고 있었다.However, in the above-described conventional configuration, in order to increase the amount of protruding from the lowering of the cassette tape, in order to increase the horizontal moving distance, it is necessary to lengthen the arm of the wiper arm, thereby increasing the height of the front loading mechanism. Had

상기 목적을 달성하기 위하여 본 발명의 자기기록재생장치는, 상기 와이퍼암의 회동지지축자체를 수평으로 이동시키고 동시에 와이퍼암을 회동하는 구성을 채택하였다.In order to achieve the above object, the magnetic recording and reproducing apparatus of the present invention adopts a configuration in which the rotating support shaft itself of the wiper arm is moved horizontally and the wiper arm is rotated at the same time.
본 발명은 상기한 구성에 의해, 수평이동거리를 길게 하는 동시에 높이를 낮게할 수 있다.According to the above configuration, the present invention can increase the horizontal moving distance and lower the height.
본 발명의 실시예에 대해서, 제1도를 참조하면서 설명한다.An embodiment of the present invention will be described with reference to FIG.
제1도는 카세트장착장치부의 평면도이다. VTR의 내림으로부터 삽입된 카세트테이프(1)는 카세트홀더(2)에 의해서 유지된다. 카세트테이프(1)를 정위치까지 삽입하면 센서(3)에 의해서 검지되고 로딩모터(4)가 동작을 시작하여 카세트홀더(2)를 이동시킨다.1 is a plan view of a cassette mounting apparatus portion. The cassette tape 1 inserted from the lowering of the VTR is held by the cassette holder 2. When the cassette tape 1 is inserted to the correct position, the cassette 3 is detected by the sensor 3 and the loading motor 4 starts to move the cassette holder 2.
제2도는 카세트장착장치부의 측면도이다. 먼저, 로딩모터(4)의 회전이 웜기어(5)에 전달되고, 웜휠(6)에 의해 회전방향이 바뀌고, 이 회전이 감속기어(7)에 의해 감속되어 미끄럼부재인 메인랙(8)에 전달되어 수평운동으로 바꾼다. 이 메인랙(8)에는 와이퍼암(9)의 회전지지축이 압입되어 있으며, 와이퍼암(9)은 상기 메인랙(8)과 측판(10)의 사이에 회전가능하게 걸림되고, 또, 와이퍼암(9)의 외주에는 기어가 형성되어 있으며 측판(10)에 고정된 와이퍼랙(11)과 맞물려있다. 이에 의해 메인랙(8)의 수평운동은 와이퍼암(9)을 수평으로 이동시키는 동시에, 와이퍼랙(11)과의 맞물림에 의해 와이퍼암(9)은 회전한다.2 is a side view of the cassette mounting apparatus part. First, the rotation of the loading motor 4 is transmitted to the worm gear 5, and the rotation direction is changed by the worm wheel 6, and this rotation is decelerated by the reduction gear 7 to the main rack 8, which is a sliding member. Is transmitted and converted into horizontal motion. The rotation support shaft of the wiper arm 9 is press-fitted into this main rack 8, and the wiper arm 9 is rotatably locked between the main rack 8 and the side plate 10, and the wiper Gears are formed on the outer circumference of the arm 9 and are engaged with the wiper rack 11 fixed to the side plate 10. Thereby, the horizontal movement of the main rack 8 moves the wiper arm 9 horizontally, and the wiper arm 9 rotates by engaging with the wiper rack 11.
상기 카세트홀더(2)는 측판(10)의 홈부(12)와 와이퍼암(9)의 홈부(13)에 의해서 걸림되어 있으며, 와이퍼암(9)이 수평으로 이동하면서 회전함으로써, 카세트홀더(2)는 특판(10) 홈부(12)를 따라서 이동하여, 카세트테이프(1)를 VTR메카니즘부의 정위치에 위치시킨다.The cassette holder 2 is locked by the groove portion 12 of the side plate 10 and the groove portion 13 of the wiper arm 9, and the cassette holder 2 is rotated while the wiper arm 9 moves horizontally. ) Moves along the groove portion 12 of the plate 10, thereby positioning the cassette tape 1 at the correct position of the VTR mechanism portion.
이상의 설명으로부터 명백한 바와같이, 카세트홀더는 와이퍼암의 회전만에 의한 수평이동만이 아니고, 와이퍼암자체의 수평이동이 추가됨으로써, 종래와 같이 와이퍼암의 암부를 길게하지 않고도 수평이동거리를 길게할 수 있다.As apparent from the above description, the cassette holder is not only horizontally moved by rotation of the wiper arm, but also horizontal movement of the wiper arm itself is added, so that the horizontal moving distance can be lengthened without lengthening the arm part of the wiper arm as in the prior art. Can be.
