Claims

[Scope of utility model registration request]

A paper ejection tray is provided so as to be movable forward and backward relative to the housing of the image forming machine between a protruding position for receiving and stacking and storing copy sheets ejected from a paper ejection section and a storage position retracted into the housing. a paper ejecting operation detection means for detecting the start of the paper ejecting operation;
A copy paper remaining detection means detects the presence or absence of copy paper on the paper ejection tray, and the paper ejection operation detection means moves the paper ejection tray from the storage position to the protruding position when the start of the paper ejection operation is detected. , a tray drive means for moving the paper ejection tray from the protruding position to the storage position only after the paper ejection operation is completed and when the copy paper remaining detecting means detects that there is no copy paper on the paper ejection tray; A paper output tray device for an image forming machine, comprising:
