KR970063111A - Cassette deck door drive system and control method - Google Patents

Abstract

The present invention relates to a cassette deck door driving apparatus and a control method thereof, in which a cassette detaching door is easily opened and closed by a driving motor, and the door opening and closing key signal is input by a user's direct key operation. The main driving unit 40 drives the door switching input unit 20 and the door motor driving unit 40 according to the key signal generated by the key input unit 10 to check the key input unit 10, the door opening / closing signal by the interruption of the switch. The door is opened and closed, but when the door is opened, the door motor driving unit 40 is operated in the forward direction to control the operation until the input signal by the door switching input unit 20 is input and count and set the number of rotation pulses of the door motor. When the door is closed, the door motor driving part 40 is operated in the reverse direction so that the door is closed, but the door motor is driven up to the rotating pulse count. A pulse that senses the number of rotation pulses by the microcomputer 30 and the door motor driver 40 for opening and closing the door by driving the door driving motor according to the control signal of the microcomputer 30 and the door driving motor. There is a feature composed of the sensing unit (50).

Claims (2)

By the key input unit 10 for inputting the door opening and closing signal due to the user's direct key operation, the door switch input unit 20 for checking the opening and closing signal of the door by the control by the switch, and by the key input unit 10 Drives the door motor driver 40 in accordance with the key signal to open and close the door, and when the door is opened, operates the door motor driver 40 in the forward direction to control the operation until the input signal by the door switch input unit 20 is input. In addition, the number of rotation pulses of the door motor is counted and set, and when the door is closed, the door motor driving part 40 is operated in the reverse direction, and the door is closed, but the microcomputer is controlled to drive the door motor to the rotating pulse count ( 30), the door motor driver 40 for opening and closing the door by driving the door driving motor according to the control signal of the microcomputer 30, and the number of rotation pulse counts by the door driving motor Characterized in that a pulse consisting of a sensor 50 which detects a tape deck door drive device. When the door key operation command for operating the door in the power-on state is input (S100-S103), and if the deck stop state is set in the forward direction, the drive motor for moving the door is driven in the forward direction. By controlling and opening the door, the number of pulses is counted and set (A) and the door driving motor is stopped and controlled until the door switch 1 ON signal is input from the door switch detecting unit which confirms the opening of the door. Step S104-S111 is set in the reverse direction and the drive motor for moving the door in the reverse direction is set in the reverse direction in the deck stop state, but the number of pulses counted by the rotating plate and the step set in step S109 are controlled. Comparing the pulses, if it is the same, the door driving motor is stopped and set in a forward direction (S112-S116). Cassette deck door drive control method. ※ Note: The disclosure is based on the initial application.
