PROBLEM TO BE SOLVED: To simplify a mechanism which electrically connects a rotating part and a fixed part at the time of measuring and adjusting the dynamic balance of a device having the rotating part like a laser scan motor. SOLUTION: A contact board 207 is provided on a rotating table 2 and is electrically connected to an accelerometer 507 and a photo sensor 510 provided on a measuring base 5 by a cord 219. In a station for measurement and confirmation of the dynamic balance, a device fixing part is provided with a power supply mechanism, and this mechanism is provided with a contact mechanism which can be moved forward to and backward from the rotating table, and it comes into contact with the contact board 207 when being moved to the rotating table. Thus, the device fixing part and the accelerometer 507 on the rotating table are electrically connected, and the constitution of the power supply mechanism is simplified. |
