检修摄像机机械传动机构故障时,要用模拟带盒进仓方法来观察磁带加载及机械机构传动过程,以便快速准确地找到故障部位。 NV-M9000、NV-M3000摄像机系统控制微处理器IC6004判断带盒进仓到位有两个条件:(1)压下带仓并锁定后,安装在带仓右上方的带盒下降开关(CAS DOWN SW)接通,IC6005(13)脚为低电平OV。(2)带仓下降锁定后,接通电源开关,加载电机通过凸轮齿轮带动方式状态开关检测带盒位置(在停止位置向反时钟方向转动一个位置后又回到原来位置),与此同时,安装在带仓中间的发光二极管发出脉冲信号(约 Overhaul camera mechanical transmission failure, the use of analog boxes into the warehouse method to observe the tape loading and mechanical transmission mechanism to quickly and accurately find the fault site. NV-M9000, NV-M3000 Camera System Control Microprocessor IC6004 There are two conditions for judging the arrival of tape cassette: (1) After the cassette is pressed down and locked, the cassette down switch (CAS DOWN SW) is turned on, IC6005 (13) feet low OV. (2) After the tape cartridge is lowered and locked, the power switch is turned on, the loading motor drives the cam switch to detect the position of the tape cartridge by means of the cam gear (after returning to the original position by rotating one position in the counterclockwise direction from the stop position), at the same time, The LED installed in the middle of the magazine sends a pulse signal (approx
