Abstract

If the setting value in the timer (7) is the same one as the stored value to the micro processor (2), the microprocessor (2) drives the servo part (3) and the drive part (4) by enabling the keyboard (1). After turning the key word part (5) to 'on' state, the microprocessor (2) turns the timer to 'on' state, and at the same time, the value in the timer (7) is set by driving the timer input part (6).

본 발명은 자기기록재생장치에 있어서, 시스템의 구동을 보호하는 시스템 구동보호장치에 관한 것으로, 특히 마이크로프로세서내에 일정값을 저장하고, 사용자가 키워드부를 온시킨 후 타이머를 통해 마이크로프로세서에 일정값을 입력시켜 그 타이머에서 입력된 일정값과 상기의 마이크로프로세서에 저장한 일정값이 동일할 경우에만 시스템이 정상 구동되게한 자기기록재생장치의 시스템 구동보호장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system drive protection device for protecting the driving of a system. More particularly, the present invention relates to a system drive protection device that protects the operation of a system. A system drive protection device for a magnetic recording and reproducing apparatus, in which a system is normally driven only when a predetermined value input by the timer and stored in the microprocessor are the same.

종래의 자기기록재생장치는 시스템의 구동을 보호하는 장치가 없었으므로 타인의 사용을 방지할 수 없는 결함이 있었다.In the conventional magnetic recording and reproducing apparatus, there is no device that protects the driving of the system, and thus there is a defect that cannot prevent the use of others.

본 발명은 이와 같은 종래의 결함을 감안하여, 마이크로프로세서에 일정값을 저장하고, 타이머를 통해 그 저장한 일정값과 동일한 값이 입력될 경우에만 시스템이 구동되게하여 시스템을 사용자가 아닌 타인의 사용을 방지하게 창안한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of such a conventional deficiency, the present invention stores a constant value in a microprocessor and causes the system to be operated only when a value equal to the stored constant value is input through a timer, thereby allowing the system to be used by someone other than the user. Invented to prevent the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시한 바와 같이 키보드(1)의 신호에 따라 마이크로프로세서(2)가 서보부(3) 및 구동부(4)를 제어하여 시스템을 구동시키는 자기기록재생장치에 있어서, 키워드부(5)가 온됨에 따라 마이크로프로세서(2)가 타이머(7)를 온시킴과 아울러 타이머입력부(6)가 정상구동되어 타이머(7)에 일정값을 세팅시키고, 그 세팅된 값과 마이크로프로세서(2)에 저장된 값이 동일할 때 마이크로프로세서(2)가 키보드(1)를 인에이블시켜 그의 신호에 따라 서보부(3) 및 구동부(4)를 구동시키게 한 것이다.In the magnetic recording and reproducing apparatus in which the microprocessor 2 controls the servo section 3 and the driving section 4 to drive the system in accordance with the signal of the keyboard 1, as shown in FIG. When the microprocessor 2 turns on the timer 7, the timer input unit 6 is normally driven to set a constant value in the timer 7, and the set value and the microprocessor 2 are turned on. When the values stored in the microprocessor 2 are the same, the microprocessor 2 enables the keyboard 1 to drive the servo unit 3 and the drive unit 4 according to the signal thereof.

이와 같이 구성된 본 발명을 제2도에 도시한 신호흐름도를 참조하여 상세히 설명하면 다음과 같다.The present invention configured as described above will be described in detail with reference to the signal flow diagram shown in FIG.

전원단자에 전원이 인가되고, 사용자가 키워드부(5)를 온시키면, 키워드부(5)의 온신호가 마이크로프로세서(2)에 입력됨과 아울러 타이머입력부(6)에 입력되므로 마이크로프로세서(2)가 타이머(7)에 온신호를 인가하여 정상구동시키게 된다.When power is supplied to the power supply terminal and the user turns on the keyword portion 5, the on-signal of the keyword portion 5 is input to the microprocessor 2 and to the timer input portion 6, so that the microprocessor 2 The on signal is applied to the timer 7 to operate normally.

이와 같은 상태에서 사용자가 타이머입력부(6)를 통해 타이머(7)에 일정값을 세팅시키고, 그 세팅된 값이 마이크로프로세서(2)에 입력되면, 마이크로프로세서(2)는 입력되는 타이머(7)의 세팅값과 저장되어 있는 일정값을 비교하여 그 값이 동일하지 않으면 키보드(1)에 디스에이블신호를 인가하여 동작하지 않게하고, 그 값이 동일하면, 타이머 오프신호를 출력하여 타이머(7)를 오프시킴과 아울러 키보드(1)에 인에이블신호를 인가하여 정상구동시키게 되므로 사용자는 키보드(1)를 통해 마이크로프로세서(2)에 시스템 구동신호를 입력시키고, 마이크로프로세서는 그 입력된 시스템 구동신호에 따라 서보부(3) 및 구동부(4)를 구동시키게 된다.In this state, when the user sets a constant value to the timer 7 through the timer input unit 6 and the set value is input to the microprocessor 2, the microprocessor 2 is input to the timer 7. Compare the setting value with the stored constant value and if the value is not the same, apply the disable signal to the keyboard 1 to disable the operation. If the value is the same, output the timer off signal to output the timer (7). In addition to turning off the signal, the enable signal is applied to the keyboard 1 to operate normally. The user inputs a system driving signal to the microprocessor 2 through the keyboard 1, and the microprocessor inputs the system driving signal. As a result, the servo unit 3 and the driving unit 4 are driven.

이상에서 설명한 바와 같이 본 발명은 타이머를 세팅시켜 그 세팅된 값과 저장된 값이 동일할 경우에만 키보드(1)를 인에이블시켜 구동시키게 되므로 저장된 값이 무엇인지를 모르는 사람이 시스템을 구동시키는 것을 방지하게 되는 효과가 있다.As described above, the present invention enables the keyboard 1 to be driven only when the set value and the stored value are the same, thereby preventing a person who does not know what the stored value is to drive the system. It is effective.
