Claims

[Scope of Claim for Utility Model Registration] 1. In a copying machine in which the original is exposed to light before the paper begins to be fed from the supply tray, it is detected that the remaining capacity of the supply tray currently in use has fallen below a specified number of sheets. a remaining amount detecting means; an exposure stopping means for temporarily stopping exposure of the original after the remaining amount detecting means determines that the remaining amount of the supply tray has become less than a predetermined number of sheets; and an exposure stopping means for temporarily stopping the exposure of the original; When the number of exposures of originals that have already been performed until the process is canceled matches the number of sheets of paper fed out from the currently used supply tray, another supply tray containing paper of the same size as this supply tray is A tray control device comprising: supply tray switching control means for controlling tray switching. 2. The tray control device according to claim 1, wherein the supply tray switching control means checks whether the supply tray can be switched each time the exposure section exposes a document. 3. When the remaining amount of paper in the switching destination supply tray is less than or equal to a predetermined value, the supply tray switching control means:
The tray control device according to claim (1) of the utility model registration, characterized in that switching thereof is prohibited.
