Abstract: A conveyor device may include first and second conveyor units, and a movable member. The first conveyor unit includes a first roller that contacts an upper surface of a sheet and a second roller that contacts a lower surface of the sheet. The second conveyor unit includes a third roller that contacts the lower surface of the sheet and a fourth roller that contacts the upper surface of the sheet. The first and second rollers and the third and fourth rollers nip and convey the sheet along a conveyance path. When the movable member is located in a first position, the first roller contacts the second roller and the third roller contacts the fourth roller. When the movable member moves to the second position, the first roller is moved away from the second roller and the third roller is moved away from the fourth roller.
