상기 샤프트 조립체(30)는 서브데크(3)에 고정되는 고정부재(31)와, 상기 고정부재(31)에 일체로 형성되어 연장된 샤프트 몸체(33)를 구비한다. 상기 고정부재(31)는 서브데크(3)에 압입결합되어 고정된다. 샤프트 몸체(33)는 고정부재(31) 보다 작은 두께 즉, 외경을 갖는다. 이 샤프트 몸체(33)에 상기 릴 조립체(40)가 회전 가능하게 결합된다.The shaft assembly 30 includes a fixing member 31 fixed to the sub deck 3 and a shaft body 33 which is integrally formed and extended to the fixing member 31. The fixing member 31 is fixed by being press-fitted to the sub deck (3). The shaft body 33 has a thickness smaller than the fixing member 31, that is, the outer diameter. The reel assembly 40 is rotatably coupled to the shaft body 33.
상기 릴 조립체(40)는 샤프트 몸체(33)에 회전가능하게 지지되는 부싱부재(41)와, 상기 부싱부재(41)와의 사이에 클러치(42)를 매개로 지지되는 기어릴(43)과, 상기 부싱부재(41)에 결합되어 함께 회전되는 릴몸체(45)를 구비한다.The reel assembly 40 includes a bushing member 41 rotatably supported by the shaft body 33, a gear reel 43 supported by a clutch 42 between the bushing member 41, and The reel body 45 is coupled to the bushing member 41 and rotates together.
상기 부싱부재(41)의 축공과 상기 샤프트 몸체(33) 사이에는 오일이 첨가된다. 상기 기어릴(43)은 상기 캡스턴 모터(5)에서 전달된 동력에 의해 회전구동되는 것으로, 외주에 기어이(43a)가 형성된다. 이 기어릴(43)과 부싱부재(41) 사이에 마련된 크러치(42)는 기어릴(43)의 동력을 부싱부재(41)로 감속하여 전달하도록 마련된 것으로, 소정의 판스프링 또는 마찰부재 등일 수 있다.Oil is added between the shaft hole of the bushing member 41 and the shaft body 33. The gear reel 43 is driven to rotate by the power transmitted from the capstan motor 5, the gear 43a is formed on the outer circumference. The clutch 42 provided between the gear reel 43 and the bushing member 41 is provided to decelerate and transmit the power of the gear reel 43 to the bushing member 41, and may be a predetermined leaf spring or friction member. have.
상기 릴몸체(45)는 부싱부재(41)에 고정되어 함께 회전되며, 상기 테이프 카세트의 테이프 릴이 안착된다.The reel body 45 is fixed to the bushing member 41 and rotated together, and the tape reel of the tape cassette is seated.
여기서, 상기 부싱부재(42)의 하면에는 반사부재 등의 센싱부(61)가 마련되며, 상기 서브데크(3)에는 상기 센싱부(61)를 감지하여 릴 조립체(40)의 회전상태를 감지하기 위한 센서(63)가 설치된다.Here, a sensing unit 61 such as a reflective member is provided on the lower surface of the bushing member 42, and the sub deck 3 senses the sensing unit 61 to detect a rotation state of the reel assembly 40. The sensor 63 is installed.
상기 오일 비산 억제수단(50)은, 상기 릴 조립체(40)의 회전시 샤프트 몸체(33)와 릴 조립체(40) 사이에 첨가된 오일이 비산되는 것을 억제시키기 위한 것이다. 이러한 오일 비산 억제수단(50)은, 샤프트 몸체(33)의 외주에 원주 방향으로 입 형성된 원주홈(51)과, 상기 고정부재(31)의 상면에 인입형성된 환형홈(53)을 구비한다. 상기 원주홈(51)은 샤프트 몸체(33)의 하단부 쪽에 원주방향으로 형성된다. 그리고, 원주홈(51)은 샤프트 몸체(33)의 축방향(x)에 대해 직각을 이루도록 샤프트 몸체(33)의 외주로부터 인입형성된다. 샤프트 몸체(33)를 타고 흐르는 오일은 상기 원주홈(51)에 수용되어 아래로 더 이상 흐르는 것을 방지함으로서, 외측으로 비산되는 것을 억제시킬 수 있다.The oil scattering inhibiting means 50 is for suppressing the scattering of the oil added between the shaft body 33 and the reel assembly 40 during the rotation of the reel assembly 40. The oil scattering inhibiting means 50 includes a circumferential groove 51 formed in the circumferential direction on the outer circumference of the shaft body 33, and an annular groove 53 formed in the upper surface of the fixing member 31. The circumferential groove 51 is formed in the circumferential direction on the lower end side of the shaft body 33. In addition, the circumferential groove 51 is formed to be pulled out from the outer circumference of the shaft body 33 to be perpendicular to the axial direction x of the shaft body 33. The oil flowing through the shaft body 33 is accommodated in the circumferential groove 51 to prevent further flowing downward, thereby preventing it from scattering outward.
또한, 상기 환형홈(53)은 고정부재(31)의 상면에 샤프트 몸체(33)를 중심으로 환형으로 인입형성된다. 바람직하게는 고정부재(31)와 샤프트 몸체(33)의 경계에 형성되어 샤프트 몸체(33)를 타고 흐르는 오일을 효과적으로 수용하게 된다.In addition, the annular groove 53 is formed to be annularly pulled around the shaft body 33 on the upper surface of the fixing member 31. Preferably it is formed on the boundary between the fixing member 31 and the shaft body 33 to effectively receive the oil flowing through the shaft body 33.
따라서, 상기 샤프트 몸체(33)를 타고 흐르는 오일은 1차적으로 원주홈(51)으로 흡수되어 아래로 흐르는 것이 방지된다. 또한, 원주홈(51)에서 미쳐 흡수하지 못한 오일은 환형홈(53)에서 2차적으로 흡수하여 수용하게 되므로, 릴 조립체(40)의 회전력에 의해 오일이 비산되는 것을 효과적으로 억제시킬 수 있게 된다. 그리고, 오일의 비산을 억제함으로써 주위 부품이 오염되는 것을 방지하고, 특히 상기 센싱부(61)와 센서(63) 등의 오염을 방지하여 오동작을 방지할 수 있게 된다.Therefore, the oil flowing in the shaft body 33 is primarily absorbed into the circumferential groove 51 and prevented from flowing downward. In addition, since the oil that has not been absorbed in the circumferential groove 51 is absorbed and accommodated in the annular groove 53 secondaryly, the oil can be effectively suppressed from being scattered by the rotational force of the reel assembly 40. In addition, by suppressing the scattering of oil, it is possible to prevent the surrounding parts from being contaminated, and in particular, to prevent contamination of the sensing unit 61, the sensor 63, and the like, thereby preventing malfunction.
한편, 본 발명의 실시예에서는 원주홈(51)을 하나만 형성시킨 것을 예로 들어 설명하였으나, 복수의 원주홈을 샤프트 몸체에 형성하는 것도 가능하다.On the other hand, in the embodiment of the present invention has been described with an example of forming only one circumferential groove 51, it is also possible to form a plurality of circumferential groove in the shaft body.
이상에서 설명한 바와 같은 본 발명의 샤프트 조립체 및 이를 채용한 테이프 레코더의 릴장치에 따르면, 샤프트 조립체에 오일 비산 억제수단을 마련함으로써, 샤프트 조립체에 릴조립체와 같은 회전시 샤프트 조립체와 릴 조립체 사이의 오일이 흘러내려 비산되는 것을 효과적으로 억제시킬 수 있다.According to the shaft assembly of the present invention as described above and the reel device of the tape recorder employing the same, the oil between the shaft assembly and the reel assembly at the time of rotation, such as a reel assembly, is provided on the shaft assembly by providing oil scattering inhibiting means. This can be effectively suppressed from flowing down and scattering.
따라서, 릴장치의 주위에 마련된 다른 부품을 오염시키는 것을 방지하여 제품 품질의 신뢰성을 향상시킬 수 있게 된다.Therefore, it is possible to prevent contamination of other parts provided around the reel device, thereby improving the reliability of the product quality.
