Abstract

PURPOSE: To reduce the weight of a magnetic circuit by enlarging the force constant distribution of a motor which drives a print mechanism part at the both edges of a motor stroke with regard to a printer which runs the print mechanism part at constant speed and at the same time, performs printing.
CONSTITUTION: In a nontype printer which runs a print mechanism part (head) at a constant speed and at the same time, performs printing like a dot printer or an ink jet printer, a carriage attached with a printing head is driven by means of a linear motor. A magnetic circuit 10 of the linear motor is composed of a center yoke 5 having a rectangular cross-section slightly longer than a motor stroke, a short side yoke 3 equipped with a permanent magnet piece 1 magnetized in a thickness direction on a permanent side on one side, a short side yoke 4 equipped with a permanent magnet piece 2 on one side and which is provided at the both ends of a motor stroke and a bottom yoke 6. Under this constitution, if a fixed current is caused to run through a coil 9 mounted on the carriage, a force constant becomes high at the both ends.
