PURPOSE:To surely prevent the breakdown of the data of a storage means or the fault of a device by letting a user discriminate by perception whether the storage means inserted from the insertion port of a device main body is attached to an information processing position in the device main body or not. CONSTITUTION:A recessed part 6 as a paper discharging part is formed at the central part of the upper surface of the printer main body 5 of a laser printer device 1, and a paper discharging tray 8 instructed so as to be movable by a jogger 7 is attached, and simultaneously, an operating panel 9 and three IC card insertion ports 11 are arranged respectively at the right side and the left side of this recessed part 6. Further, a perception giving means 81 to let the user perceive whether IC cards 65 to 67 are attached or not is provided. Thus, an information processor is never made to work while the IC card 65 to 67 is dislocated from the information processing position. |
