SOLUTION: An opening/closing mechanism comprises a latch 125 provided on an opening/closing cover 102, a first stopper 129 which once changes the advancing direction of the latch 125 in a direction to block the advancing route of this latch 125 and again, returns the advancing direction to the original advancing route, and a second stopper 130 to bold the opening/closing cover 102 in a closed condition by hooking the latch 125 moved through this first stopper 129. The cover 102 is once regulated by the first stopper 129 and the second stopper 130, and then, closed smoothly step by step. |
