Title: Cloth printing device
Inventor: NIIMI AKIKO
IPC: B41J2/01
Filed: 2003-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To hold a cloth in a good flatness by simply removing wrinkles of the cloth placed on a platen and eliminating the unevenness.  <P>SOLUTION: A cotton cloth 40 for generating a static friction force to the cloth 50 is attached to an upper face 12a of the platen 12. An end 12b of the upper face 12a of the platen 12 becomes a region where the cotton cloth 40 is not present and the static friction force substantially does not work. At the time when the cloth 50 is set on the platen 12, the cloth 50 is retained by the friction force of the cotton cloth 40 to the cloth 50. Because of the retention by the friction force, the unevenness of the cloth 50 can be removed only by softly rubbing a surface of the cloth 50 by a hand and stretching the wrinkles P. The flatness of the cloth 50 is kept by the friction force in this state. Since the friction force does not work at the end 12b of the platen 12, a side part 50a of the cloth 50 is slid smoothly.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
