본 고안은 공기의 흡입력을 이용한 비디오 테이프 레코오더(VTR)의 테이프 로오딩 및 이송장치에 대한 것이다.The present invention relates to a tape recording and conveying apparatus for a video tape recorder (VTR) using suction force of air.
종래의 브이티알은 기구 구동식으로 구성되어 있기 때문에 그 구조가 매우 복잡하고 많은 부품이 소요되어 공수가 증가됨은 물론 모든 장치가 작동될 때 테이프에 무리한 힘을 주게되며, 플레이 상태에서는 순간적으로 리버어스(Reverse) 플레이가 불가능하며 모든 작동을 순간적으로 처리할 수 없는 등 많은 문제점이 있었다.Conventional VTIAL is mechanically driven, so its structure is very complicated and many parts are required, which increases the number of maneuvers and puts excessive force on the tape when all the devices are operating. (Reverse) There are many problems, such as impossible to play and unable to handle all operations at once.
본 고안은 이와 같은 점들을 보다 효과적으로 개선하기 위해 헤드드럼의 양측에 각각 흡입팬을 착설하여 테이프를 공기의 흡입력으로 로오딩이 되도록 하므로 구조가 간단하고, 모든 동작이 순간적으로 간단하게 처리되도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.The present invention is designed to install the suction fan on each side of the head drum to improve the above points, so that the tape can be loaded by the suction force of the air, so the structure is simple and all the operations are processed at the moment. When described in detail according to the accompanying drawings as follows.
메인테크(1) 위에 설치된 헤드드럼(2)의 양측에 다수의 유입공(3)이 경사면으로 된 주면에 방사상으로 뚫어지고, 하단에는 링기어(7)를 각각 부착한 테이프 이송륜 (4)(4')을 지지륜(5)위에 착설하여 각각 일측면만 개구된 커버(6)(6')를 복착하고, 구동모우터(8)(8')의 축(9)에 끼워진 기어(10)(10')에 의해 회전되는 전동기어(11) (11')와 링기어(7)를 치합시키며, 이송륜(4)(4')의 내부에는 팬모우터 (12)를 각각 착설하고 그 축(12')에는 흡입팬(13)(13')을 메인데크(1)의 하부에 위치되도록 축착하여 밀폐캡(14)(14')으로 복착하며 흡입되는 공기는 배기공(15)을 통해 배출구(16) (16')로 각기 배출되게 하고, 리일디스크(17)(17')는 구동모우터(8)(8')의 축(9)하단에 끼워 고정시킨 구동풀리(18)에 의해 연동되는 연동풀리(19)(19')의 마찰차(20) (20')와 결합시켰으며, 커버(6)(6')의 일측에는 각각 가이드핀(21)(21')을 착설하여서된 것이다.Tape feed wheels (4) having a plurality of inlet holes (3) radially drilled on the inclined surface of the main surface (2) on both sides of the head drum (2) installed on the main tech (1), the ring gear (7) attached to the lower end (4 ') is mounted on the support wheel (5), and the cover (6) (6') opened only on one side, respectively, and the gears fitted to the shaft (9) of the driving motor (8) (8 ') ( 10) The electric gears 11, 11 'and the ring gear 7 rotated by 10' are engaged with each other, and the fan motor 12 is installed inside the feed wheels 4, 4 ', respectively. And suction shafts 13 'and 13' on the shaft 12 'so as to be positioned below the main deck 1, and are seated in the sealing caps 14 and 14'. Through the outlets 16 and 16 ', respectively, and the discs 17 and 17' are fixed to the lower end of the shaft 9 of the drive motors 8 and 8 '. 18) is coupled to the friction difference 20, 20 'of the interlocking pulleys 19, 19' that are interlocked by 18, and on one side of the cover 6, 6 '. Each guide pin 21, 21 'to the hayeoseo chakseol.
미설명부호 “22”는 카세트고, “23”은 테이프이며,“24”는 전동기어 지지축이고,“25”는 테이프를 이송하는 작동을 시켜주는 스위치이며,“26”은 스위치를 작동시켜주는 레버이고,“27”은 흡입공이며,“28”은 베어링이다.Unexplained symbol "22" is cassette, "23" is tape, "24" is electric gear support shaft, "25" is a switch to transfer tape, and "26" is a switch Lever, “27” is suction hole, “28” is bearing.
이와같이 구성된 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.
리일디스크(17)(17')위에 카세트(22)를 안착시키면 헤드드럼(2)의 양측에 착설된 이송륜(4)(4')내의 모우터(12)가 각각 작동되어 흡입팬(13)(13')을 회동시켜 주므로 이 흡입팬(13)(13')의 흡입력에 의해 커버(6)(6')의 개구된 부분을 통해 외부의 공기가 이송륜(4)(4')의 경사진 주면에 뚫어진 다수의 유입공(3)을 거쳐 내측으로 유입되기 때문에 테이프(23)은 제1도에서 조보는 바와같이 양측의 커버(6) (6')에서 개구된 부분을 통해 이부분으로 노출되는 이송륜(4)(4')의 경사면과 이들 사이를 거쳐 드럼(2)에 로오딩이 된다.When the cassette 22 is seated on the rail discs 17 and 17 ', the motors 12 in the transfer wheels 4 and 4' mounted on both sides of the head drum 2 are operated to operate the suction fan 13, respectively. 13 'is rotated so that outside air is transferred to the transfer wheels 4 and 4' by the suction force of the suction fans 13 and 13 '. Since the tape 23 flows inwardly through a plurality of inlet holes 3 drilled on the inclined main surface of the tape, the tape 23 passes through the openings in the covers 6 and 6 'on both sides as shown in FIG. The drum 2 is loaded through the inclined surfaces of the transfer wheels 4 and 4 'exposed to the portion and between them.
이렇게 하여 로오딩이 오나료되면 가이드핀(21)(21')에 테이프가 밀착되므로 커버(6)(6')의 개구부가 막히게 되어 흡입력이 커지게 되고, 이에의해 레버(26)가 당겨져 스위치(25)를 동작시켜주어, 모우터(8)(8')가 동시에 작동되어 이에 의해 기어 (10)(10')가 회전되고 이에 치합된 전동기어(11)(11')와 링기어(7)를 각각 회전시켜주게 되어 이송륜(4)(4')이 회전되며, 또 모우터(8)(8')의 축(9) 하단에 각각 부착된 풀리(8)는 각기 풀리(19)(19')를 회전시켜 그 상면의 마찰차(20)(20')를 회전시켜 주므로 마찰차(20)(20')가 각기 리일디스크(17)(17')를 이송륜(4)(4')과 동시에 회전시켜 주기 때문에 테이프(23)가 정상적인 주행이 되는 것이다.In this way, when the raw material is finished, the tape is brought into close contact with the guide pins 21 and 21 'so that the openings of the covers 6 and 6' are blocked so that the suction force is increased, whereby the lever 26 is pulled and the switch is pulled. (25), the motors (8) and (8 ') are operated simultaneously so that the gears (10) and (10') are rotated and engaged with the electric gears (11) (11 ') and ring gears ( 7) respectively rotate the feed wheels (4) and (4 '), and the pulleys (8) attached to the lower end of the shaft (9) of the motor (8) and (8'), respectively, are pulleys (19). (19 ') to rotate the friction difference (20, 20') of the upper surface, so that the friction difference (20, 20 ') each of the rail disk (17, 17') transfer wheel (4) It rotates at the same time as 4 ', so that the tape 23 runs normally.
이와같이 주행이 되는 과정에서 흡입팬(13)(13')은 계속 작동을 하므로 커버 (6)(6')의 개구 부분을 지나게 되는 테이프는 흡입력에 의해 계속 회전되는 이송륜 (4)(4')에 개구부분을 통해 흡입되는 공기는 메인데크(1)위 흡입공(27)을 통해 하향되어 밀폐캡(1)(14')에 의해 형성된 공간부(a)를 거쳐 배기공(15)과 배출구(16) (16')를 통과하여 배출되는 순환작용이 이루어진다.Since the suction fans 13 and 13 'continue to operate during the driving process, the tape passing through the opening of the covers 6 and 6' is continuously rotated by the suction force. The air sucked in through the opening portion is lowered through the suction hole 27 on the main deck 1, and passes through the exhaust hole 15 through the space portion a formed by the sealing cap 1 and 14 '. Circulation is effected through the outlets 16 and 16 '.
이와같이 작동되는 본 고안은 미세조정을 할 때에는 팬 모우터(12)의 속도를 제어하면 가능하며, 슬로우 모션 또는 리버어스등과 같은 여러가지 동작을 기능를 할 때에는 모우터(8)(8')의 속도를 제어하면 모든 동작을 쉽게 진행시킬 수 있게 되는 것으로 테이프의 로오딩을 위한 로오딩폴의 구성이 필요없어 기구적으로 매우 간단하여 지며, 또 공기의 순환으로 내부 습기가 쉽게 건조되기 때문에 이슬맺힘 현상이 현저히 줄어들고 고장율이 저하되며, 플레이상태에서 순간적으로 모든 동작을 조절 할수 있게 되는 등 매우 효과적인 고안이다.The present invention operated in this way is possible to control the speed of the fan motor 12 when making fine adjustments, and the speed of the motors 8 and 8 'when performing various operations such as slow motion or reverse. It is possible to easily proceed all the operation by controlling the, and it is very simple mechanically because there is no need of the configuration of the loading pole for the loading of the tape, and dew condensation occurs because the internal moisture is easily dried by the circulation of air. It is a very effective design that can be significantly reduced, failure rate is reduced, and all movements can be adjusted instantaneously in play state.
