Abstract:
The magnetic fixing device comprises a clamping plate having a fixing surface to which a clamping object is fixed and plural magnetic force generation mechanisms. The magnetic force generation mechanisms each comprise a magnetic material member facing the fixing surface, plural permanent magnets arranged around the outer periphery of the magnetic material member, a first Alnico magnet placed on the back of the magnetic material member, and a first coil for switching the polarity of the first Alnico magnet, and can be switched between the absorption state in which the clamping object is adsorbed and the non-absorption state in which the clamping object is not adsorbed. An operation state indication mechanism capable of presenting an indicator indicating that the plural magnetic force generation mechanisms are in the absorption state or in the non-absorption state is provided on the fixing surface or outer periphery of the clamping plate.
