Abstract A counting device for counting a number of image forming operations of an image forming apparatus. The counting device includes a registering device for registering a plurality of identification codes and a comparing device for comparing an identification code stored in a portable memory card with the plurality of identification codes registered in the registering device. A first memory counter counts a number of image forming operations of the image forming apparatus when the comparing device matches the identification code stored in the portable memory card with at least one of the plurality of identification codes registered in the registering device. A second memory counter counts a number of image forming operations of the image forming apparatus when the comparing device does not match the identification code stored in the portable memory card with any of the plurality of identification codes registered in the registering device. Thus, the number of copying operations can be both collectively and individually counted.
A counting device for counting a number of image forming operations of an image forming apparatus, said counting device comprising: registering means for registering a plurality of identifications codes; comparing means for comparing an identification code stored in a portable storing means with said plurality of identification codes registered in said registering means; first memory means for counting a number of image forming operations of said image forming apparatus when said comparing means matches said identification codes stores in said portable storing means with at least one of said plurality of identification codes registered in said registering means; and second memory means for counting a number of image forming operations of said image forming apparatus when said comparing means does not match said identification codes stored in said portable storing means with any of said plurality of identification codes registered in said registering means.

The counting device of claim 1, wherein said portable storing means comprises a card having a non-volatile memory.
Claim 4
Dependent Claim
73 words
The counting device of claim 1, wherein said image forming apparatus comprises validity determination means for determining in validity of said identification code stored in said portable storing means, said validity determination means enabling said image forming apparatus to perform image forming operations when said identification code is determined to be valid, and wherein said counting device comprises means for being activated responsive to said validity determination means enabling said image forming apparatus.
