Abstract:
    A blower ( 10 ) includes: at least two or at least three acoustic sensors or vibration sensors ( 31 a to 31 c) attached to a casing ( 12 ); and a position specifying means ( 34 ) for specifying a position of a source of abnormal sound or abnormal vibration from signals detected by the acoustic sensors or vibration sensors. When the position of the abnormal portion is specified in this way, a proper countermeasure can be taken quickly. Further, the blower ( 10 ) preferably includes an alarm output judging means ( 35 ) for judging whether or not an alarm should be outputted according to the position of the source of the abnormal sound or abnormal vibration specified by the position specifying means. A laser oscillator ( 100 ) having the blower ( 10 ) is also provided.
