Claims

[Scope of utility model registration request]

first, second, third, and fourth transistors connected in series to form a bridge between a power source and a reference potential point, and each of these first, second, third, and fourth transistors; First and second current paths for causing the motor to rotate forward or reverse can be selectively formed with respect to the motor connected between the midpoints and the first, second, third, and fourth transistors. A forward rotation switch and a reverse rotation switch are connected, and a first current path is connected to the forward rotation switch and the reverse rotation switch so as to be able to prohibit the formation of the opposite current path among the first and second current paths. and a second diode.
