PURPOSE:To prevent occurrences of faulty action due to intrusion of radiation noise by employing optical fiber in an image signal supply line connecting an image recording part with an image signal supply part. CONSTITUTION:An image signal supply part 10 is composed of an electric circuit 11 and a light emitting part 12, and an image recording part 20 comprises a light receiving part 21, a head drive 22 and a printing head 23. The light emitting part 12 and the light receiving part 21 are connected in such a manner that an optical fiber 32 which is an image signal supply line may transmit optical information. The electric circuit 11 and the head drive 22 have connections with other lines VH, VCC, G for transmission of electric information. Due to the employment of optical filter as an image signal supply line as described above, radiation noise is not allowed to intrude into a power line-signal line or a signal-signal line, the thus eliminating possibilities of faulty action occurrence.
