Abstract

본 발명은 브이씨알의 기능모드절환에 따른 소음방지방법에 관한 것으로, 고속으로 회전하는 다이렉트모드에서 일정속도로 회전하는 슬립모드로의 절환시에 일정시간의 정지단계를 경유하여 진행하도록 하므로써, 고속회전에 의해 릴에 남아있던 관성력을 완전히 제거한 후 다음모드로 진행하게 되므로 이에따라 기어들의 접촉소음을 완전히 제거할 수 있음은 물론 모드절환에 따른 기어의 맞물림동작이 정확히 이루어지게 되므로 이에따라 구동의 정확성도 증가하도록 된다.The present invention relates to a noise prevention method according to the function mode switching of V-CAL, and to proceed through the stop step of a certain time at the time of switching from the direct mode rotating at high speed to the sleep mode rotating at a constant speed, Since the inertia force remaining on the reel is completely removed by the rotation, it proceeds to the next mode. Therefore, the contact noise of the gears can be completely eliminated, and the gearing operation of the gear is performed correctly according to the mode switching. Will be done.

Description

Noise prevention method according to the function mode switching

Claims

In the sleep mode determination step (S3) and the sleep mode determination step (S3), it is determined whether or not the setting signal for setting the sleep mode that rotates at the low speed is input in the direct mode that is rotated at a high speed during V tape playback. As a result, when the setting signal for setting the sleep mode is input, the mode switch is prepared to stop the gapstan motor and drive the loading motor to separate the gears that were rotating at high speed, and to engage the gears that are engaged at the low speed. After the step S4 and the mode switching preparation step S4, the brake mode is executed to stop the driving operation of the loading motor just before the gears which rotate at low speed are engaged with each other, thereby removing the inertia forces of the gears which have already been rotated at high speed. During the step S5 and during the brake mode execution step S5, the set time T according to the brake mode execution has been reached. When the detection time (t) reaches the setting time (T) as a result of judging during the setting time elapsed judging step (S6) and the setting time elapsed judging step (S6) for judging, the loading motor is driven to have a predetermined gap. Noise control method according to the function mode switching of V-AL, characterized in that consisting of the setting mode execution step (S7) for completely engaging the gears of the low-speed rotation was stopped.
