例43、机心原有自动停机功能,但磁带走完后,键却拾不起来。故障现象:当磁带已经走完后,无论在录、放音或是快进、倒带时,键均不能自动复位。故障分析:对于采用机械结构(参看图27)来实现全自动停机的机心(即录、放音、快进、倒带键在磁带走完后均能自动跳键),出现这种故障有以下几种因素(以三洋牌M4500K型收录机为例):由于自 Example 43, the original automatic shutdown machine features, but after the tape is finished, the keys can not pick up. Symptom: When the tape has been finished, no matter in recording, playback or fast forward, rewind, the keys are not automatically reset. Failure Analysis: For mechanical movement (see Figure 27) to achieve automatic shutdown of the movement (ie recording, playback, fast forward, rewind button after the tape can automatically jump after the end of the key), there is such a failure The following factors (in Sanyo brand M4500K tape recorders, for example): Since
