Copying apparatus

A copying apparatus comprising:

• processing means for copying;
• numeral key means for entering numeric data necessary for a copying operation;
• first memory means for storing numeric data entered from said numeral key means;
• display means for displaying a numeral based on the numeric data stored in said first memory means;
• second memory means having a plurality of memory locations for storing plural numeric data transferred from said first memory means;
• storage control key means for causing the numeric data stored in said first memory means to be transferred to said second memory means and stored therein;
• reading means for reading out numeric data stored in said second memory means;
• storage control means for controlling storage of the numeric data in said second memory means, when numeric data involved in a first copy mode has been stored in a first memory location of said second memory means, said storage control means causing numeric data involved in a second copy mode stored in said first memory means to be stored in a second memory location of said second memory means, which is different from said first memory location thereof, by means of an input operation of said storage control key means, without cancelling the numeric data involved in the first copy mode stored in the first memory location of said second memory means;
• and
• processing control means for controlling said processing means in accordance with numeric data read out from said second memory means by said reading means so as to carry out a copying operation in a copy mode according to the numeric data stored in said second memory means.
