ABSTRACT:
Disclosed is a device for carrying a printing head which comprises, a first guide shaft disposed in parallel with a platen, a second guide shaft disposed in parallel with the first guide shaft, a carriage slidably supported by the first and second guide shafts, a printing head mounted on the carriage so as to be opposite to the platen, and a permanent magnet provided on the carriage so as to be opposite to an outer peripheral surface of the first guide shaft. The magnetic attraction force of the magnet with respect to the first guide shaft is set to be larger than gravity acting onto the printing head and the carriage when the magnet is arranged to be in opposition to a lower side portion of the outer peripheral surface of the first guide shaft, while set to be large enough to prevent the carriage from floating due to printing force of the printing head against the platen when the magnet is arranged to be in opposition to an upper side portion of the outer peripheral surface of the first guide shaft.
