PROBLEM TO BE SOLVED: To solve the problem that switching between a rotation driving means with a sensor and a rotation driving means without a sensor is complexed. SOLUTION: When an SPM 11A with a sensor is mounted, a low signal (L) is outputted from an SPM driver 10A to a control part 2, and when an SPM without a sensor is mounted, a high signal (H) is outputted from an SPM driver 10B to the control part 2. The control part 2 is switched to the rotation drive control of the SPM 11A with the sensor when it receives the low signal, or is switched to the rotation drive control of the SPM 11B without the sensor when it receives the high signal. |
