A circuit board (40) includes control circuit patterns (51) and first drive circuit patterns (53). A base (70) maintains the circuit board (40) in a state in which the base (70) is opposed to a portion of the circuit board (40), in which the control circuit patterns (51) are formed, across a space that allows control circuit elements (46) to be mounted at the circuit board (40). A line module (60) includes second drive circuit patterns (68) electrically connected to the first drive circuit patterns (53) so as to constitute a part of lines of a drive circuit, and is sandwiched between a portion of the circuit board (40), in which the first drive circuit patterns (53) are formed, and the base (70). |
