PROBLEM TO BE SOLVED: To supply a transfer current value flexibly corresponding to various parameters of a print form by providing a main control part and an auxiliary control part having a specific number of signal lines and a specific number of current control circuits. SOLUTION: A control unit 10 has the main control part 12 and auxiliary control part 24 and is connected to 1st and 2nd signal lines 2 and 3 to generate one output 6. For example, the main control part 12 is connected to two signal lines 2 and has four current control circuits 16 to 22, but generally connected to (m) signal. lines 2 and has 2m current control circuits inside. The auxiliary control part 24 is connected to one signal line 4 and connected to one current control circuit 28. Their numbers are not limited to as mentioned above. When the number of 1st and 2nd signal lines is (n) and the number of 2nd current control circuits is s, the number of the 1st and 2nd current control circuits, is (2n-s+S) and a relation s=n-m (m: number of 1st signal lines) is born; and a transformer part can generate and output 2n kind of transfer currents by a combination of 1st and 2nd values. |
