<p>PURPOSE:To decrease the drive torque of a cam mechanism by giving an angular displacement to a shaking member when a recording medium is located near the extreme position of the downstream side of the loading direction so as to part a stopper and a lock member slightly thereby giving the angular displacement to the shaking member. CONSTITUTION:When a grip member 13 is at the pause position, a lock member 35 provided to a shaking member 14 supporting the grip member 3 is in the 2nd angular position and engages with a locking lever 84 being a stopper. Thus, the weight of the grip member 3 in this case is not transmitted to a sliding projection 57 being a follower and a cam member 73 thereby causing only a possibly small force between the cam face 60 of a cam member 73 and the sliding projection 57. That is, when the grip member 3 is going to load a recording medium from the pause position, the drive torque required to drive the cam member 73 is reduced and then the constitution to generate the torque is miniaturized.</p> |
