Claims

[Scope of Claim for Utility Model Registration] (1) A paper output tray that is extendable and retractable in the direction in which recording paper is ejected, a size detection means that detects the size of the recording paper, and an expansion/contraction detector that detects the expansion and contraction state of the paper output tray. means, a control means for generating an output when it is determined that the recording paper size is large and the paper ejection tray is shrunk based on the detection contents of both of the means, and the ejection tray is extended by the output from the control means. An electrophotographic apparatus comprising: a display means for displaying a message indicating that the image should be displayed. (2) The above-mentioned paper ejection tray includes a base tray part that is fixedly attached to the main body of the electrophotographic apparatus, and a base tray part that is slidably attached to the base tray part in the paper ejection direction, and the end on the side of the base tray part is attached to the base tray part. 1. An electrophotographic apparatus comprising a slide tray part that can freely protrude and retract from an edge of a main body of the electrophotographic apparatus, and the elongation and contraction detecting means detects protrusion and retraction of the end part of the slide tray part.
