Claim:
A printer comprising: a main body; a guiding plate secured within the main body; a cover rotatably connected to the main body and comprising at least one resisting block facing the guiding plate; and a shielding assembly arranged between the cover and the guiding plate, and comprising a shielding plate rotatably connected to the main body and at least one elastic element secured to the shielding plate, wherein the shielding plate is in an upright state when no external force is exerted on the shielding plate, when the cover is rotated to cover the main body, the at least one resisting block resists the at least one elastic element, causing the shielding plate to rotate from the upright state to a horizontal state, and causing a portion of the shielding plate to contact the guiding plate, when the cover is rotated to an open state, the at least one resisting block disengages from the at least one elastic element, causing the shielding plate to rotate from the horizontal state to the upright state.
