An image recording apparatus allows a single drive device to drive an ink cartridge conveying unit and ink hammers, thereby reducing the production cost. A drive motor supplies a drive force to rollers that convey ink cartridges and link mechanisms that push solid ink pieces out of ink cartridges. A planetary gear is provided to make it possible to select whether to transmit a drive force from the drive motor to the conveying rollers. Therefore, the apparatus is able to transmit a drive force to the conveying rollers only during conveyance of an ink cartridge, and to prevent transmission of drive force to the conveying rollers when the drive motor drives the link mechanisms, while employing the single drive motor to drive the conveying rollers and the link mechanisms.
