(Prior Art) In an ink jet printer, it is necessary to dry a recorded image written by ink droplets after the recording and writing process is completed. For this type of drying treatment, a heating means, a blowing means or a means combining these are usually used. However, applying such means to a printer not only complicates the apparatus unnecessarily, but also requires a great deal of This is not preferable because it involves power consumption, and furthermore, when a high-density recording image is written, the recording paper is discharged without drying the ink image sufficiently. There is a problem that the surface of the preceding recording paper is stained by semi-dry ink due to contact with the subsequent recording paper.

To cope with such a problem, the apparatus disclosed in Japanese Patent Application Laid-Open No. 1-145545 temporarily holds the discharged recording paper on a pair of rails provided on both sides of a paper discharge tray, and then holds these rails. The recording paper is dropped onto the paper discharge tray by rotating in the retreat direction, and the recording paper is written on the previous recording paper using the recording / writing time without complicating the apparatus. It is excellent in that the ink image is dried. However, since this type has a structure in which the left and right rails are pivotally supported at fixed positions, it has a problem that it cannot cope with recording papers of different sizes. In the case where the left and right rail surfaces are different from each other, the recording paper may fall obliquely and may not be properly stacked on the paper discharge tray.
