Abstract

PURPOSE: To facilitate the assembly with a less number of parts and lower power consumption by selection of letters in plural shifts with one electromagnetic coil employing a permanent magent.
CONSTITUTION: With the rotation of the driving shaft 2, the type wheel 3 is turned. When the desired type 4 on the type wheel 3 is turned to the given position, the electromagnetic coil 7 is energized in synchronization with this. Thus the mobile member 5 made of magnetic material is excited to produce the polarity at the tip thereof. When the polarity is arranged as the north pole in the drawing, a replusion is generated as the tip of the member 5 is the same in the polarity as the plate of the permanent magnet 9 while an attraction is generated as it is different in the polarity from the plate 10 of the magnet 8. The repulsion and the attraction combines to turn the member 5 counterclockwise so that is engages the rachet 1 to halt the type wheel 3. Then, after types corresponding to one line are arranged at the printing position, the platen 14 is pressed over four rows of the type to print on a printing paper through the ink ribon 15.
