description The utility model relates to a dial circuit of fax machine, which is composed of a keyboard 1, a CPU 2, a dial plate 3, a strobe unit 4, and a sampling circuit 5, wherein the CPU 2 and the dial plate 3 are connected with the keyboard 1 through the strobe unit 4, and the sampling circuit 5 is connected with the control end of the strobe unit 4. The sampling circuit 5 takes samples of the electric signal of working power supply of a fax machine, when the working power supply is powered on, the strobe unit 4 controls the CPU and keyboard 1, and accomplishes electrical connection; when the working power supply is powered off, the strobe unit 4 controls the dial plate 3 and the keyboard 1 and accomplishes electrical connection. The utility model has the advantages that phone call can be carried out in condition of power off, and the simple structure.
