If the conditions are matched to the (Y in step S8), and the process proceeds to step S7, the copy at the front detachable condition is possible state.

On the other hand, when the original set tray 3 is attached and detached,
Moreover, if the setting data before and after the attachment / detachment do not match, the process proceeds to step 9 to determine whether or not the job ends, and returns to step S2. If the processing is not completed, the process proceeds to step S10, where two pieces of mismatched data before and after the attachment / detachment of the document set tray 3 are displayed on the display means 21 and a message warning that the data is mismatched is displayed.
This may be alarm means such as an alarm.

Subsequently, the operation proceeds to step S11. Here, by operating the selection knob 19 provided on the document set tray 3, it is possible to select whether to copy under the condition before or after detaching or to copy under the condition after detaching. Then, in step S12, copying under the condition selected in step 11 is enabled.

When the copy start button is pressed in the state of steps 7 and 12, copying is performed. If it is determined in step S1 that the document set tray is not mounted, or if the switching means 18 is switched to a position where the setting data is not input from the document set tray 3 to the main body in step S2, Proceeding to S5, the condition setting from the main body operation unit becomes possible.

With the above configuration, it is possible to set copy conditions at a location remote from the copying apparatus.
There is no need for the copy requester to notify the operator or the copy conditions, and the operator does not need to set and input the requested copy conditions in the operation unit of the copying apparatus. Can be.

Here, a case where the document set tray 3 is used as a normal tray will be described. The operator mounts the empty document set tray 3 on the copying apparatus 1 and switches the input switching means 18 on the tray 3 to the non-input side. As a result, input from the document set tray to the main body is prohibited, and input from the main body operation unit is enabled. Therefore, the operator only has to perform a normal operation of setting a document on the tray 3, setting and inputting copy conditions on the main body operation unit, and pressing a copy start button.

By preparing a plurality of the original setting trays 3, the efficiency of the copying operation can be further improved. Also,
By providing the input switching means, setting from the copying machine main body side is possible, and the tray can be effectively used.
