Abstract
A rotation transmitting mechanism includes a first cylindrical body, a second cylindrical body arranged parallel to the first cylindrical body, a rotary body disposed parallel to the first cylindrical body, and circumscribed with the first and second cylindrical body, a pressing unit for pressing one of the first and second cylindrical bodies against the other of the first and second cylindrical bodies so as to make the first and second cylindrical bodies contact each other, and a moving unit for moving the rotary body toward a point where the first cylindrical body contacts the second cylindrical body so as to inhibit contact of the first cylindrical body with the second cylindrical body, and to contact the rotary body with the first and second cylindrical bodies, and for retreating the rotary body in a direction opposite to the aforementioned point so as to permit contact of the first cylindrical body with the second cylindrical body, which contact is caused by the pressing unit. The rotation transmitting mechanism can smoothly transmit rotation because transmission of rotation is performed by frictional force.
