Image reading device and wiring method

An FFC coupling a sensor substrate and an AFE substrate includes a configuration in which a ground line is sandwiched between a first lead wire and a second lead wire that are signal lines that transmit a read signal from the sensor substrate to the AFE substrate, and includes a configuration in whi...

Zusammenfassung:An FFC coupling a sensor substrate and an AFE substrate includes a configuration in which a ground line is sandwiched between a first lead wire and a second lead wire that are signal lines that transmit a read signal from the sensor substrate to the AFE substrate, and includes a configuration in which a third lead wire having a smaller voltage change than the signal line is sandwiched between two signal lines that are at least one set other than a set of the first lead wire and the second lead wire, wherein each of the signal lines is coupled to a ground pattern of the sensor substrate and is coupled to a ground pattern of the AFE substrate, and the third lead wire is coupled to a ground pattern of the sensor substrate and is coupled to a ground pattern of the AFE substrate.
