The first pressing roller set is installed in a receiving member, which is arranged at a terminal side of the outer casing. The first pressing roller set includes a first rotating shaft and a first pressing roller. The separating device is sheathed around the first rotating shaft and exposed outside the receiving member. When the upper cover is opened, the upper cover is contacted with the separating device, so that the separating device is moved to shift the first rotating shaft. |
