系统控制电路是整台录像机的核心部分,有时也称其为录像机指挥中心,显然这部分电路是十分重要的。系统控制电路的主要作用,一是接受录像机面板功能操作键钮送来的各种方式指令(如重放、快进、倒带等)信号,然后据此发出相应的控制信号,令机构和电路系统严格按一定程序动作并且进入相应的工作状态;二是当机构或电路发生故障及进入某种状态(如录像带重放完毕、静止画面持续出现一定时间和倒带结束等)时,控制录像机进入停机(停电)自动保护状态或转换到规定的另一工作状态(如重放结束自动倒带 System control circuit is the core of the entire video recorder, sometimes called the VCR command center, apparently this part of the circuit is very important. The main function of the system control circuit, one is to accept the various commands (such as replay, fast forward, rewind, etc.) sent by the operation of the video recorder panel function keys, and then issue the corresponding control signals accordingly, so that institutions and circuits System in strict accordance with a certain sequence of actions and into the corresponding state of work; Second, when the institution or circuit failure and into a state (such as video playback is completed, the still picture appears a certain period of time and the end of the rewind, etc.), control the video recorder to enter Shutdown (power failure) Automatically protect the state or switch to the provisions of the other working state (such as the end of automatic rewind
