Abstract:
An anti-abrasive flat flexible cable for use with an image scanner for electrically connecting a carriage with a circuit board, said flat flexible cable being bent at different positions thereof with the movement of said carriage relative to said circuit board under a scanning platform, and comprising:a flexible conductive portion having a first end electrically connected to said circuit board and a second end electrically connected to said carriage for signal transmission between said circuit board and carriage; a flexible insulating portion wrapping around said flexible conductive portion for protecting said flexible conductive portion; and a flexible spacer portion attached onto said flexible insulating portion, and positioned between said flexible insulating portion and said scanning platform for isolating said flexible insulating portion from said scanning platform, wherein said scanning platform is made of glass, and said flexible spacer portion is made of a material selected from a group consisting of Teflon, polyoxylated methylene (POM) and a composite material including Nylon and POM, and a hardness of said flexible spacer portion and a frictional coefficient between said flexible spacer portion and said scanning platform are small enough to substantially render no chip on contact.
