Abstract: A small-sized printer has a carriage moving in front of a platen. A print wheel is rotatably mounted on the carriage and coupled to a print wheel gear. The print wheel gear meshes with two worm gears which extend parallel to the platen. A rack-like cam also lies parallel to the platen and is followed by rocking lever which drives a pivoted hammer support. A pivoted hammer on the pivoted support strikes the inside of the print wheel, forcing an inked character to print on the paper, and rolling the character on the paper as the carriage moves. The two worm gears are powered by a motor which acts through a print drive. Their rotation is controlled so that the print wheel is rotated for print character selection by rotating both worm gears to turn the print wheel gear, the carriage is caused to move along the print line by stopping rotation of one of the worm gears, and the carriage is caused to return to its original position by stopping the other worm gear.
