PURPOSE:To control quickly the time of driving start and end of a load, by driving a load corresponding to a voice word discriminating result, only when the driving start and end to a desired load are indicated by a common driving indicating switch. CONSTITUTION:When a push-on switch SW4 is turned on, an output signal S0 of an inputting circuit 5 falls to L from H in response to it, and in response to this fall, a voice discriminating device 3a is set to an input voice holding state. Subsequently, when a voice word to a desired load is generated from a microphone 2, a voice discriminating operation is executed by the device 3a, to which one of loads L1-Ln the input voice word correspond is discriminated, and an output SK corresponding to a discriminating result in output signals S1-Sn is set to H. When the SW4 is turned on again, a B input is selected by a switching circuit COSK, a transistor DK is turned on, and in a period of time when the SW4 is on, the load LK is driven through a relay RL. Subsequently, when the SW4 is turned off, the DK is cut off, the output SK is set to L, the circuit COSK selects an A input, and the load LK is reset to a nondriving state. |
