PURPOSE:To enable a user to be surely notified of the mislaying of original while lessening the burden on the operation of the management device by alarming the state of the mislaying of original by analyzing the signal level of a received mislaying signal of original upon receipt of the mislay signal of original radio-transmitted from an image forming device. CONSTITUTION:A control circuit 9 is constituted to enable to recognize at what distance the operator carrying the contactless type management device 2 is apart from a copying machine body 1 by subjecting the reception intensity of the prescribed signal which is transmitted from a transmitter 7 and is received by a receiver 8 to level management. The control circuit 9 analyzes the signal level of the mislaying signal of original received by the circuit when the signal receiver 8 receives the mislaying signal of original radio-transmitted from the transmitter 7 of the copying machine body 1. The control circuit warns and notifys the person carrying the contactless type management device 2 that he is going to part from the copying machine body 1 in the state of mislaying the original, from a notification section 10, if the received signal is below the prescribed level. |
