PROBLEM TO BE SOLVED: To dispense with an expensive damper, to reduce the number of components, to improve the assembling workability, to reduce the manufacturing cost and to improve the operability. SOLUTION: The mechanism is provided with an opening/closing cover 21 which is rotated around a rotary shaft, a cover gear 21b which is rotated together with the cover 21 around the rotary shaft, a gear train equipped with a gear engaged with the cover gear 21b within the prescribed angle range of the cover gear 21b, a driven member driven by a driving force transmitted by the gear train, and a driving motor for transmitting the driving force to the gear train, and when the cover 21 is opened/closed, the driven member/the driving motor is rotated. |
