Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a copying machine management device that centrally manages a plurality of copying machines at one location.

Traditionally, when a single copying machine is used by multiple departments, the value of copies (cumulative number of copies, etc.) has not been managed separately for each department. .

For example, in Japanese Patent Application Laid-open No. 72057, which was filed by the present applicant and has already been published, there is a unique code indicating the department of use recorded on a portable information recording medium (magnetic card, etc.) distributed to each department of use. in a predetermined storage area of the data storage device characterized by the code,
A cumulative storage of the value of copies made in its usage department is disclosed.

Nowadays, in the information age, the need for copying services is rapidly increasing in government offices and businesses.

In user organizations such as schools that have a large number of users, there are cases in which multiple copying machines are installed and any copying machine can be used by a large number of users or by a user department that is a group of specific users. Can be seen.

Even in this type of use of copying machines, it is necessary to comprehensively manage the value of copies for each department (or user) that uses the copying machines, from the perspective of sharing copying costs among beneficiaries. has been done.

However, in the management device for a single copying machine that has been proposed in the past, only the usage value of each usage department made by that copying machine is stored in the data storage device of each copying machine, and the above-mentioned copying If the conventional device is applied as is in the usage pattern of a group of machines, the use value information of each usage department will be dispersed to each copying machine, and the burden of human labor such as collecting and aggregating the information will be large. Moreover, this burden tends to increase as the number of copying machines increases and the number of departments using them increases.

Furthermore, a problem arises in that it is not possible to grasp the usage status of each copying machine, such as paper shortage, developer shortage, malfunction, etc.

Therefore, the present applicant further proposed that
As disclosed in the publication, the copy data for each department code used from each of the multiple copiers is transmitted to the management 'J1+i' station, and cumulatively added by department and the number of copies on the copier side. Store the memorized data as necessary.
In addition, maintenance information such as paper jams and failures of each copying machine can be transmitted to the management device and displayed. We are proposing a device.

However, since each copying machine does not have a means to store usage value information such as the number of copies per department and maintenance information by type, the transmission path becomes longer due to expansion in scale.
Accurate transmission may not be possible due to noise etc.
Alternatively, there is a possibility that the stored data may be lost due to some reason on the management device side, but in such a case, a problem arises in that the data cannot be collected again.

Furthermore, since maintenance information is only transmitted to the management device F1 and displayed each time it occurs, there is a problem in that maintenance information must be constantly monitored.

This invention was made in order to solve the problems caused by the conventional copying machine management device as described above. etc. and maintenance information of the copier are stored so that they can be communicated with the management device that manages the group of copiers at any time, and maintenance information of each copier is stored at preset times. The purpose is for the management device to automatically collect the messages and display or print them out.

In this specification, the term "copying machine" refers not only to general copying machines but also to machines having a copying function, such as facsimile machines and copying machines. Furthermore, ``Department J shall refer to a classification necessary for management such as a company, department, group, or individual.
