(13) and the upper cylinder (1) having a screw hole 23 and the shaft 10 is fixed to the shaft, and the set screw 15 is fixed to the screw hole 23 of the upper cylinder (1) and then screw A motor cylinder rotor which is screwed onto the head fixing part 14 by a screw 16 and screwed to the fixing part 13 which is an upper part of the upper cylinder 1 as a screw 17. (3), a rotary transformer (7) fixed to bending (BONDING) on the lower side of the upper cylinder (1) and soldered and fixed to the video head (4) by the connecting portion 22, and the upper cylinder ( 1) the shaft 10 and the shaft is installed on the lower side, the upper side of the rotary transformer (7) bend fixed to the stator (8) and the lower side of the PCB (9) to the rotary transformer pin (21) The lower cylinder (2) to be fixed and the motor cylinder bush (6) provided with a screw (18) for fixing the shaft (10) on the motor cylinder rotor (3) on the upper cylinder (1) are integrally fixed as an adhesive (19). The motor cylinder stator 5, the motor cylinder stator 5 and the PCB 9 which are fixed to the upper and lower sides of the upper and lower cylinders 1 and 2 and the PCB 9 are connected by the connector 24 and block (to one side). The preamp PCB 11 having 25) is constructed.

이와같은 구성으로 이루어진 본 고안은 상부실린더(1)에 베어링(B) (B')을 삽입 고정 시킨 후 비디오 헤드(4)의 높이조정용 세트스크류(15)를 나사식 고정시키고 하측으로 비디오헤드(4)를 스크류(16)로 나사식 고정시키며 고정부(13)에 모터실린더 로터(3)를 스크류(17)로 나사식 고정시킨다.According to the present invention having such a configuration, the bearings B and B 'are inserted into and fixed to the upper cylinder 1, and then the set screw 15 for adjusting the height of the video head 4 is screwed and the video head is lowered. 4) is screwed to the screw 16 and the motor cylinder rotor (3) is screwed to the fixing part 13 with a screw (17).

그리고 상부실린더(1) 하측의 돌턱(12)에 로터리 트렌스(7)를 밴딩고정하고 비디오헤드(4)의 로터리 트렌스(7)를 연결부(22)로서 납땜하여 연결시키면 실린더의 회전부위가 완료된다.When the rotary transformer 7 is banded and fixed to the lower jaw 12 of the upper cylinder 1 and the rotary transformer 7 of the video head 4 is soldered and connected as the connecting part 22, the rotation part of the cylinder is completed. .

또한, 하부실린더(2)에 로터리트렌스(7)의 고정자(8)를 밴딩고정시킨후 샤프트(10)를 끼우며 상, 하부 실린더(1) (2)를 조립한다.Further, after fixing the stator 8 of the rotary transformer 7 to the lower cylinder 2, the shaft 10 is fitted and the upper and lower cylinders 1 and 2 are assembled.

이때 로터리트렌스(7)와 고정자(8) 사이의 공간(틈새)가 유지되도록 한다.At this time, the space (gap) between the rotary transformer 7 and the stator 8 is maintained.

그리고 샤프트(10)에 판스프링(20)을 삽입시킨후 모터실린더부시(6)와 일체로된 모터실린더고정자(5)를 판스프링(20)상에 조립시키며 베어링(B) (B')에 예압을 가하기 위하여 일정한 하중을 가하여 스크류(18)로 샤프트(10)에 나사식 고정한다.Then, the plate spring 20 is inserted into the shaft 10, and then the motor cylinder stator 5 integrated with the motor cylinder bush 6 is assembled on the plate spring 20 to the bearings B and B '. In order to apply a preload, a fixed load is applied to the shaft 10 by screws 18.

여기서 샤프트(10)는 하부실린더(2)에 견고히 축 고정된다.Here, the shaft 10 is firmly axially fixed to the lower cylinder 2.

또한, 하부실린더(2)의 하측으로 PCB(9)를 로터리트렌스핀(21)으로 고정시킨 후 PCB(9)와 모터실린더고정자(5)의 양 전단에서 컨넥터(24)로서 프리-앰프 PCB(11)에 납땜 연결시킨다.In addition, the PCB 9 is fixed to the lower side of the lower cylinder 2 with the rotary transformer pin 21, and then the pre-amp PCB (A) is connected as the connector 24 at both front ends of the PCB 9 and the motor cylinder stator 5. 11) Solder to

따라서 전원을 인가시키면 인가된 전원은 모터실린더고정자(5)와 PCB(9)를 통해 모터(M)를 구동시켜 상부실린더(1)와 비디오헤드(4)가 회전하며 기존의 방식대로 신호가 입, 출력되어 재생기록을 수행하게 되는 것으로 상부실린더(1)를 회전시키는 모터(M)가 상부실린더(1)에 설치되어 있으며 모터 실린더 고정자(5)와 모터실린더부시(6)를 일체화하고 샤프트(10)가 하부실린더(2)에 축고정되어 회전하지 않도록 구성되어 있으므로 실린더의 전체 높이를 대폭 줄일 수 있는 효과가 제공되는 것이다.Therefore, when the power is applied, the applied power drives the motor M through the motor cylinder stator 5 and the PCB 9 so that the upper cylinder 1 and the video head 4 rotate, and a signal is input in the conventional manner. The motor M for rotating the upper cylinder 1 is installed in the upper cylinder 1 so as to output and reproduce the recording. The motor cylinder stator 5 and the motor cylinder bush 6 are integrated with each other. 10) is fixed to the lower cylinder (2) is configured so as not to rotate is to provide an effect that can significantly reduce the overall height of the cylinder.

또한, 기존의 베어링예압용 부시와 모터실린더를 삭제하므로 부품수를 감소시켜 공수를 절감함과 동시에 원가를 절감하는 효과가 제공된다.In addition, since the existing bearing preloading bush and the motor cylinder are deleted, the number of parts is reduced, thereby reducing labor and cost.

또한, 모터의 신호 연결과 비디오헤드의 신호 전달용 PCB가 프리엠프 PCB와 상, 하측에서 평행으로 직접 연결되며 로터리 트렌스의 로터가 상부에 부착되므로 보다 정확한 신호 전달이 가능하게 된다.In addition, the signal connection of the motor and the PCB for signal transmission of the video head are directly connected in parallel with the preamplifier PCB in the upper and lower sides, and the rotor of the rotary transformer is attached to the upper side, thereby enabling more accurate signal transmission.
