PROBLEM TO BE SOLVED: To provide optical equipment where vibration and noise made from a motor unit is restrained to be low. SOLUTION: By making the area of a supporting region S1 where a supporting member 11 supports a motor 10 equal to or under 1/2 of the area of the end face 10b of the motor, the motor is supported by the supporting member 11 through the end face of the motor orthogonal to the output shaft of the motor. By such constitution, the natural frequency of the motor unit is changed, and resonance with the rotational frequency of the motor 10 is prevented from occurring. COPYRIGHT: (C)2007,JPO&INPIT
