摘要： PROBLEM TO BE SOLVED: To detect the output open-circuit of multiple channels inexpensively by an output open-circuit detection device of a multiple-channel output device. SOLUTION: Coils 10a-10d of a stepping motor are connected between a driving circuit 12 and a ground and high-resistance resistors 24a-24d are connected in parallel with output transistors 20a-20d. A diode OR circuit 34 is connected to output terminals 13a-13d. When either one of the coils 10a-10d is disconnected, the voltage of a driving voltage source 22 is outputted to the output terminals via the resistors 24a-24d and the potential of the output terminals is maintained at a high level. In this case, the output level of the diode OR circuit 34 becomes high and the output is charged to a timer capacitor 72, and a high-level voltage is outputted from a comparison circuit 40 when the charged voltage exceeds a specific value.
