본 고안은 플로피 디스크 드라이브(FDD)의 헤드캐리지 구동장치에 관한 것이다.The present invention relates to a head carriage drive of a floppy disk drive (FDD).
플로피 디스크 드라이브의 헤드캐리지는 디스켓에 정보를 기입 또는 독출하기 위한 필수부품이며 정밀한 동작에 의해 구동되도록 설계되어 있다. 이러한 장치에 있어서 종래에는 제1도와 같은 장치가 사용되었다.The head carriage of the floppy disk drive is an essential component for writing or reading information on a diskette and is designed to be driven by precise operation. In such a device, a device such as that of FIG. 1 has been conventionally used.
마그네틱 헤드(10)를 구비하는 캐리지(11)의 일측은 안내축(12)에 결합하고 타단에 고정 설치되는 스틸벨트(13)의 일측 끝단을 스텝모터(14)축의 허브(15)와 결합시켜서 사용하였다.One side of the carriage 11 having the magnetic head 10 is coupled to the guide shaft 12 and one end of the steel belt 13 is fixed to the other end and the hub 15 of the step motor 14 shaft Used.
이러한 장치는 스텝모터(14)가 구동함에 따라 연동하는 허브(15)에 스틸벨트(13)가 감기거나 풀어지는 방향으로 작동하게 되며 이에 따라 스틸벨트의 장력에 따라 캐리지가 안내축(12)에 안내되어 전후로 구동하면서 플로피 디스크에 정보를 기입 또는 읽어내는 역할을 수행하게 된다.Such a device operates in a direction in which the steel belt 13 is wound or unwound by the hub 15 that interlocks as the step motor 14 is driven so that the carriage is moved to the guide shaft 12 according to the tension of the steel belt. It is guided and driven back and forth to write or read information on the floppy disk.
그러나 이와 같은 종래 플로피 디스크 드라이브의 헤드캐리지 구동장치는 스탭모터와 캐리지 사이에 스틸벨트가 존재하게 되어 있어 이 세가지의 복합 구조로 인하여 캐리지의 직선운동시 공진형상으로 인한 소음이 발생하며 스틸벨트를 풀리와 캐리지에 조립할 때 스틸벨트를 풀리에 먼저 감아 양방향으로 펼쳐서 양끝의 구멍과 캐리지의 양축 돌기에 고정시켜야 하므로 작업에 많은 불편함이 있으며 작업능률을 저하시켰다.However, the head carriage driving device of the conventional floppy disk drive has a steel belt between the step motor and the carriage, and thus, due to the combination of these three structures, noise is generated due to the resonance shape during the linear movement of the carriage. When assembling to the carriage, the steel belt should be wound around the pulley first and unfolded in both directions to be fixed to the holes at both ends and the two-axis projection of the carriage, which causes a lot of inconvenience and reduced work efficiency.
본 고안은 상기와 같은 결점을 해소하기 위하여 안출된 것으로서 플로피 디스크 드라이브(FDD)의 헤드 케리지 구동장치에 있어서 스텝모터의 풀리와 캐리지의 접촉부의 표면과 직접 연결시키므로 스텝모터의 회전운동을 캐리지의 직선운동으로 변환시켜 캐리지의 구동시 소음이 발생되지 않고, 캐리지가 원활하게 구동할 수 있도록 하고 캐리지에 스텝모터의 풀리를 직접 접촉하도록 조립하므로 조립하기 편리함에 본 고안의 목적이 있다.The present invention was devised to solve the above-mentioned drawbacks. In the head carriage driving device of the floppy disk drive (FDD), the step motor is directly connected to the pulley of the stepper motor and the surface of the carriage, so that the rotational motion of the stepper motor is straight. It is an object of the present invention to be assembled and assembled so that the carriage can be smoothly driven and the carriage is directly contacted to the pulley of the step motor by converting the motion to drive the carriage.
상기와 같은 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.
제2도를 참조하여 본 고안의 구성을 설명하면 플로피 디스크 드라이브의 본체(1)에 설치되는 안내축(2)에 헤드케리지(3)의 일측이 끼워지고 타단의 연장부(4)의 상면은 스텝모타(5)의 허브(6)와 맞닿으며 하측면은 본체에 축지된 아이들 로울러(7)와 접촉되게 설치된 것으로서 도면중 미설명부호 8은 아이들 로울러를 축지하기 위한 리브이다. 이때 허브(6)는 헤드캐리지(3)와 직접 맞닿아 회전하므로 연질의 마찰력이 큰 재질을 사용하는 것이 바람직하며 헤드케리지의 밑면(4')에 아이들 로울러(7)와 맞닿는 부분은 부식시켜 마찰력을 증대시켰다.Referring to Figure 2 describes the configuration of the present invention one side of the head carriage 3 is fitted to the guide shaft (2) installed in the main body (1) of the floppy disk drive and the upper surface of the extension portion 4 of the other end is The lower side is in contact with the hub 6 of the step motor 5 and is installed to be in contact with the idle roller 7 axially stored in the main body, and reference numeral 8 in the drawing denotes a rib for axially idling the roller. At this time, since the hub 6 rotates in direct contact with the head carriage 3, it is preferable to use a material having high soft frictional force. The portion contacting the idle roller 7 on the underside 4 'of the head carriage is corroded by friction. Increased.
이와 같이 구성된 본 고안의 작용 효과는 다음과 같다.Effects of the present invention configured as described above are as follows.
스텝모터(5)에 결할된 허브(6)는 외주를 약간의 탄성을 지니고 마찰력이 강한 고무가 둘러싸고 있으며, 본체(1)의 리브(8)에 축지된 아이들 로울러(7)를 허브(6) 하단에 설치하여 헤드캐리지(3)의 연장부(4)의 밑면에서 자유로이 회전하도록 설치되어 있다. 그러므로 스텝모터(5)가 회전하면서 허브(6)가 회전하게 되고, 이에 따라 허브(6)와 캐리지의 연장부(4)가 서로 접촉하여 마찰력에 의하여 헤드캐리지(3)가 안내축(2)에 안내되어 구동하게 되는 것이며 이때 하단을 받치고 있는 아이들 로울러(7)는 헤드캐리지의 구동을 보다 원활하게 작동하도록 한다.The hub 6 attached to the step motor 5 is surrounded by a rubber having strong elasticity and strong friction on the outer circumference, and the idle roller 7 axially held on the rib 8 of the main body 1 by the hub 6. It is attached to the lower end, and is installed so that it may rotate freely in the bottom surface of the extension part 4 of the head carriage 3. As shown in FIG. Therefore, as the step motor 5 rotates, the hub 6 rotates, so that the hub 6 and the extension part 4 of the carriage come into contact with each other and the head carriage 3 is guided by the frictional force. The idle roller 7 which is guided to and driven by the lower end is configured to more smoothly operate the head carriage.
상기와 같은 본 고안에 의하면 플로피 디스크 드라이브에 헤드캐리지를 구동함에 있어서 스텝모터의 풀리와 로울러에 의하여 캐리지의 접촉부 표면과 연질의 허브 표면이 직접 연결시켜 스텝모터의 회전운동을 해드 캐리지의 직선운동으로 변환시키므로 캐리지의 구동시 소음이 발생을 억제하며 헤드캐리지가 원활하게 직선운동을할 수 있으며 풀리와 캐리지를 직접 연결하므로 조립성을 향상시키는 잇점이 있다.According to the present invention as described above, in driving the head carriage to the floppy disk drive, the contact surface of the carriage and the soft hub surface are directly connected by the pulley and the roller of the step motor, so that the rotational movement of the step motor is performed by the linear movement of the head carriage. The conversion reduces the noise when driving the carriage, the head carriage can be smoothly linear movement, and the pulley and the carriage is directly connected, there is an advantage to improve the assembly.
