PURPOSE:To prevent the breakage of an element as well as the generation of radiated noise, due to abnormal current, by a method wherein an address signal is outputted from a motor control circuit and a motor driving pattern is provided with a time (t) for preventing a pair of transistors from being put ON simultaneously. CONSTITUTION:A memory device ROM, generating a driving pattern, is connected to a motor control circuit MC, an inverter In1 and an amplifier Am1 are connected to the output terminal of the signal PA of the memory device ROM, the inverter In2 and the amplifier Am2 are connected to the output terminal of another signal PA', the inverter In3 and the amplifier Am3 are connected to the output terminal of a signal PB and the inverter In4 and the amplifier Am4 are connected to the output terminal of the other signal PB'. The motor driving pattern is provided with a time (t) for preventing a pair of transistors Tr1, Tr2, or transistors Tr2, Tr4, for example, from being put ON simultaneously. |
