PROBLEM TO BE SOLVED: To provide a recording device in which even under an environment where an AC power source condition is poor and a ratio between positive and negative of an AC voltage is not 1:1, an accurate power duty control of load can be performed.SOLUTION: In a recording device including a power control part for controlling a power source part having a triac, which supplies power to each of the devices, the power control part includes in a control circuit a zero-cross interval latch circuit and triac-on output timing setting circuit in such a state that they correspond to an AC power source differently in positive and negative, and each of the circuits is alternately switched at a zero-cross timing of the AC power source so as to perform power duty control of load. |
