<P>PROBLEM TO BE SOLVED: To provide a recording data transmission apparatus and a recording device which can evade the influence of noise on the recording data caused by the on/off operation of a switching means on a recording head side. <P>SOLUTION: A driving signal COM is a signal to be applied to an ejection drive element disposed for each of nozzles of the recording head, and includes driving pulses DP1 to DP4 to be selected for determining one dot. A printing data stop control unit controls a printing data transmission unit to temporarily stop the transmission of the data S1, SP and a clock CLK based on a switching signal CH that determines a timing to turn on/off a switch circuit located on the recording head side, and also, determines a timing to switch among the driving pulses DP1 to DP4. <P>COPYRIGHT: (C)2010,JPO&INPIT |
