PURPOSE: To regularly load recording paper after printing and a document after ending reading on a cassette cover by pivotally supporting a base end part by a rear end cover, and also providing a frame-shaped movable discharge paper receiver energized to the front with the base end part serving as the center, so that the long scaled document can be stored.

CONSTITUTION: A cassette has a frame (movable discharge paper receiver) 25 turn-energized to a front (cover 24) side around a pivotally supporting part by a coil spring or the like while is pivotally a base end part 25a supported by an upper end edge of the rear end cover 24. The frame 25, in the case of drawing out rearward the rear end cover 24, is tumbled to the front by spring tension, to insert the point end downward of an upper cover 22. The frame plays a role of bridging for closing an opening formed between the upper cover 22 and the ear end cover 24. In this condition, in the case of discharging long scaled recording paper and document onto the upper cover 22, the recording paper or the like, whose point end edge is slid smoothly rearward along the frame 24, can be stacked.
