Abstract:
1. A flexible cable structured to be connected with a data input and output contact for performing data input and/or data output and a plurality of contacts other than the data input and output contact, the flexible cable comprising: a data signal layer which is formed with a data signal pattern structured to be connected with the data input and output contact and a plurality of signal patterns connected with a plurality of the contacts; a first disconnection detecting signal layer which covers a front face of the data signal layer and is formed with a disconnection detecting signal pattern structured to transmit a disconnection detecting signal for detecting its own disconnection; a second disconnection detecting signal layer which covers a rear face of the data signal layer and is formed with a disconnection detecting signal pattern structured to transmit a disconnection detecting signal for detecting its own disconnection; wherein the flexible cable is formed in a multilayer structure comprising the data signal layer, the first disconnection detecting signal layer and the second disconnection detecting signal layer; wherein a shield pattern is formed in the first disconnection detecting signal layer and/or the second disconnection detecting signal layer at a position avoiding the disconnection detecting signal pattern; wherein the data signal pattern is formed so as to be covered by the disconnection detecting signal pattern of the first disconnection detecting signal layer and the disconnection detecting signal pattern of the second disconnection detecting signal layer; and wherein at least a part of the signal pattern is formed so as to be covered by the shield pattern.
