PURPOSE:To prevent copying paper of undesirable size from being fed erroneously after interruptive copying, by displaying the warning which shows that sheets of copying paper of size corresponding to an original interrupted in copying are not stored in a paper feeding set. CONSTITUTION:Display devices 56a-56f are turned on selectively by detectors 32a-32f to display which one of sizes JIS (Japanese Industrial Standard) A3, B4, A4, B5, A5, and B6 the sheets of copying paper in a paper feeding cassette corresponds to. A dispaly device 58 is turned on when sheets of copying paper of size which corresponds to an original interrupted in copying through the depression of an interruption key 41 is not set in the machine body, and displays, for example, a word ''wrong cassette'' to instruct an operator to set the corresponding paper feeding set. Thus, sheets of copying paper of undesirable size are prevented from being fed erroneously. |
