Description

다중디스크 플레이어용 트레이의 개폐속도 제어 방법 및 그 장치Control method of opening and closing speed of tray for multi-disc player and device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 장치에 의한 트레이 구조와, 그 트레이 이동에 따른 위치감지 및 개폐속도 제어회로도, 제2도는 본 발명의 장치의 동작설명을 위해 트레이 개폐동작에 따른 마이컴의 출력펄스 파형도, 제3도는 본 발명방법을 설명하기 위한 플로우 챠트.1 is a tray structure according to the apparatus of the present invention, a position sensing and opening / closing speed control circuit diagram according to the movement of the tray, and FIG. 2 is an output pulse waveform diagram of the micom according to the opening and closing operation of the tray for explaining the operation of the apparatus of the present invention. 3 is a flow chart for explaining the method of the present invention.

Claims (3)

오픈/클로스키 입력정보에 따라 모터(3)의 회전방향을 판단하여 오픈/및 클로스 명령에 따른 모터를 정속도로 구동시킴과 동시에 트레이(4)가 그에 대응하는 방향으로 이동개시하고, 모터구동에 따른 정속도를 감속시킬 위치에 도달하면 모터속도를 감속시키며, 감속위치 경과후 트레이(4)이동정지 종료점이면 모터구동을 정지시킴과 동시에 다음키 입력을 받기 위해 대기하고 1회 로딩동작을 종료시키도록 이루어짐을 특징으로 하는 다중 디스크 플레이어용 개폐속도 제어방법.The rotation direction of the motor 3 is determined according to the open / closed input information to drive the motor according to the open / close command at a constant speed, and the tray 4 starts to move in the corresponding direction, and the motor drive is started. When the motor reaches the position to decelerate the constant speed, the motor speed is decreased. If the tray 4 stops moving after the deceleration position has elapsed, the motor drive is stopped and the motor waits for the next key input and ends the one-time loading operation. Opening and closing speed control method for a multi-disc player, characterized in that made to. 디스크를 안착시키는 트레이(4)와, 상기 트레이(4)를 이동시키는 모터(3)에 의해 오픈키 및 클로스크 조작에 따라 대응하는 방향으로 이동시키도록 제어하는 트레이 개폐장치에 있어서, 상기 트레이(4)의 이동에 따른 속도 감속위치를 검출하는 제1및 제3스위치(SW1)(SW3)와, 상기 트레이(4)의 오픈 및 클로스 이동정지 종료점을 검출하는 제2및 제4스위치(SW2)(SW4)와, 상기 제1내지 제4스위치(SW1-SW2)들의 온/오프 동작상태에 따라 시스템제어 및 트레이(4)이동용모터(3)를 정속도 또는 감속도로 제어시키는 마이컴(1)과, 상기 마이컴(1)의 제어출력 필스에 따라 그에 대응하는 전압으로 증폭시키는 증폭기(2)를 상호 연결하여서 구성됨을 특징으로 하는 다중디스크 플레이어용 트레이의 개폐속도 제어장치.In the tray opening and closing apparatus which controls the tray 4 to seat a disk, and the motor 3 which moves the tray 4 to move to a corresponding direction according to an open key and a cloak operation, The tray ( First and third switches SW 1 (SW 3 ) for detecting a speed deceleration position according to the movement of 4), and second and fourth switches for detecting end points of opening and closing of the tray 4. SW 2 ) (SW 4 ) and control the system 3 and the motor for moving the tray 4 to the constant speed or deceleration according to the on / off operation state of the first to fourth switches SW 1 to SW 2 . And a microcomputer (1) and an amplifier (2) for amplifying to a voltage corresponding to the control output field of the microcomputer (1). 제2항에 있어서, 상기 트레이(4)는 그의 하부면 양단에 트레이(4)의 이동에 따라 속도감속위치 검출용 제1및 제3스위치(SW1)(SW3)를 온/오프 시키도록 내측면(a)(b)를 경사지게한 돌출부(5)(7)와, 드레이(4) 오픈동작시 종료위치점 검출용 종료감지스위치(SW2)를 온/오프 시키는 돌출부(6)가 형성됨을 특징으로 하는 다중디스크 플레이어용 트레이의 개폐속도 제어장치.3. The tray (4) according to claim 2, wherein the tray (4) turns on / off the first and third switches (SW 1 ) (SW 3 ) for detecting the speed reduction position in accordance with the movement of the tray (4) at both ends thereof. Protruding portions 5 and 7 having inclined inner surfaces a and b, and protruding portions 6 for turning on and off the end detection switch SW 2 for detecting the end position during the opening operation of the tray 4 are formed. Opening and closing speed control device for a multi-disc player tray, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
