An image forming apparatus comprises an inner memory, first checking means, second checking means, a mode selector, judging means and a portable memory. The portable memory is adapted to be connected to the main body of the apparatus and memorizes a portable memory identification number to identify the same portable memory and a plurality of usable apparatus numbers to represent usable image forming apparatuses which become usable by the connection of the same portable memory. The inner memory memorizes an apparatus identification number to identify the image forming apparatus and a plurality of acceptable portable memory numbers to represent portable memories acceptable for the same image forming apparatus. The first checking means checks if the apparatus identification number coincides with any of the usable apparatus numbers, and the second checking means checks if, the portable identification number coincides with any of the acceptable portable memory numbers. The mode selector selects a check mode which determines a combination of checks to be performed by the first and the second checking means, and the judging means allows usage of the image forming apparatus based on the result of the combined checks. |

DETAILED DESCRIPTION It is a primary object of the present invention to provide an image forming apparatus characterized in that: even when various kinds of copiers are provided, an outer memory means such as a memory card, IC card, magnetic card and a remote control means to which an electric wave or light is applied, is utilized so that checking the ID number stored in the memory card with that registered in the copier can be easily and accurately performed.
In order to attain the aforementioned object, the present invention is to provide an image forming apparatus comprising: an outer memory means which can be connected to the image forming apparatus; a first memory means which stores a plurality of available image forming apparatus ID numbers stored in said outer memory means, and the image forming apparatus ID number; a first check means which checks said image forming apparatus ID number with said available image forming ID numbers; a second memory means which stores an outer memory means ID number stored in said outer memory means, and a plurality of available memory means ID numbers; a second check means which checks said outer memory means ID number with said available outer memory ID numbers; a check mode selecting means which selects a check mode from the combination of said first and second check means; an image formation permission judging means which judges image formation permission from the result of the check according to the check mode selected by the check mode selection means; and a control means which carries out image formation according to the result of judgment conducted by the image formation permission judging means.
In the image forming apparatus of the present invention, a highly functional outer memory means is utilized which can be attached to and detached from the image forming apparatus, and a plurality of available image forming apparatus ID numbers are stored in the outer memory means.
Further, the image forming apparatus is provided with first and second memory means which store ID numbers corresponding to the plurality of outer memory means
