Title:
PRINTER DEVICE
Document Type and Number:
Japanese Patent JP2833918
Kind Code:
B2
Abstract:

PURPOSE: To eliminate a main scanning width limit to obtain wide applications by a method wherein bearings rotating about vertical shafts are provided at four corners of a lower surface of a square chassis, and a printing head is provided on the center of the chassis.
CONSTITUTION: After printing paper 10 is fixed on a plane of a drafting table or the like, a printer device is disposed at the upper left-hand corner of the printing paper 10. In this state, a stepping motor 7 is rotated. The directions of bearings 4a, 4b, 4c, and 4d are changed so that stepping motors 3a, 3b, 3c, and 3d are positioned upward. When the stepping motors 3a, 3b, 3c, and 3d are rotated in this state, rubber balls 2a, 2b, 2c, and 2d rotate about vertical shafts. In this manner, main scanning is conducted by moving the chassis 1 rightward and alternately conducting the operation of a printing head 8 and the movement of the chassis 1. When the printer device reaches the right end of the printing paper 10, one main scanning action is completed.
