Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying machine that uses a card, and more specifically, a copying machine that allows copying operations by inserting a key check card to manage the number of copies for each department. Regarding copying machines.

Conventionally, in order to manage the number of copies made on a copying machine, counter units were distributed to multiple departments, and each counter unit was attached to the copying machine body to count the number of copies made for each counter unit. was. In the past, when counting the number of copies for all departments, it was necessary to collect all the counter units, which was inconvenient. Furthermore, it is possible to make copies using counter units that have been distributed to other departments, and if a department loses a counter unit, it is not possible to prohibit copying in that department. Furthermore, in order to eliminate the complexity of the counting work by the counter unit, a card with a department code recorded is distributed to each department, and by using that card, the counter in the copier can count the number of copies for each department. There is a prior art that allows for counting, but even in this prior art, it was not possible to prohibit people in other departments from making copies using the lost card.

An object of the present invention is to solve the above-mentioned technical problems and to provide a copying machine that can prohibit copying in any department.
