To prevent interference between a recording medium and a recording unit after recording by providing a discharge holding member provided with a horizontal supporting unit arranged on the substantially same plane with the conveying direction and the discharging direction of the recording medium and arranging a penetration preventing member which is connected to the end part on the discharge means side of the horizontal supporting part and is inclined downward.

In a discharging action of a recording sheet P in an ink jet recording device, when the tip of the recording sheet P passes a discharge part 11, the tip, which is suspended because of its self-weight, is moved forward toward a horizontal supporting part 7a by means of guide of an inclined penetration preventing member 8. In this way, an image is recorded by means of a recording head 15 while the tip part of the recording sheet P is supported by means of the horizontal part 7a. According to the progress of image forming, the rear end of the recording sheet P passes the discharge part 11, and then, the rear end of the recording sheet P is dropped onto the penetration preventing member 8 because of conveyance by means of a discharge roller 18 and its self-weight so as to be hung along the inclination of the penetration preventing member 8, so that interference with the recording unit 10 is prevented.
