The right direction manipulation button(20') of the octa-direction switch(20) is manipulated, and the output of the 1st NOR gate(41), the logic gate device(40), connected to the right side direction handling button(20c), becomes a low level. So, the 1st transistor(51) and the 4th transistor are connected. As a result, the 1st motor(60) runs to the forward direction and drives the side mirror to the right. In case the left side direction button(20d) is handled, the output of the OR gate(42) of the logic gate(40) becomes a high level, and as the output of the 2nd NOR gate(43) becomes a low level, the 2nd and the 3rd transistors are connected.
