Apparatus and method for maintaining and controlling electronic apparatus provided with communication function
First Claim
1. A maintenance control apparatus for electronic apparatuses each provided with a data communication function, the maintenance control apparatus comprising:
- central control means for holding maintenance control data comprising information on each of a plurality of electronic apparatuses, each of the electronic apparatuses being identified in accordance with predetermined stored information, the central control means being connectable selectively to any of the electronic apparatuses through an associated data communication link;
portable maintenance terminal means selectively connectable to any of the electronic apparatuses and including memory means having limited memory capacity sufficient for storing received maintenance information needed for servicing at least one of the electronic apparatuses but insufficient for simultaneously storing maintenance information needed for servicing others of the plurality of electronic apparatuses;
detecting means for detecting identification information of one of the electronic apparatuses;
transmitting means for transmitting the detected identification information to the central control means through the data communication function of the one electronic apparatus and an associated one of the data communication links;
the central control means responding to the detected identification information to determine, from the stored maintenance data, operation data corresponding to the one electronic apparatus, and transmitting the operation data to the one electronic apparatus through the associated data communication link;
the portable terminal means further having;
receiving means for receiving the operation data from the one electronic apparatus; and
display means for displaying selected data including the received operation data;
the portable terminal means receiving an operator input of state data indicative of at least the operating and trouble states of the one electronic apparatus, and transmitting the operator input state data to the one electronic apparatus;
the central control means receiving from the one electronic apparatus the operator input state data and state data detected by the one electronic apparatus; and
the central control means determining maintenance guidance data on the basis of the state data, and transmitting the guidance data to the portable terminal means through the one electronic apparatus for operator use in servicing the one electronic apparatus;
whereby the portable terminal means can be used portably to provide needed servicing for any of the plurality of electronic apparatuses with the limited memory capacity of the memory means.

Abstract
The invention is capable of displaying to an operator a guidance for performing an accurate operation in accordance with a state of a copying machine, and at the same time the invention does not require a huge volume memory and a processor for analyzing data in the portable terminal device with the result that the cost can be reduced and the device of the invention can be reduced in size. The portable terminal device is provided for the display and input reception of the maintenance control data in such a manner the portable terminal device can be connected to the copying machine. The maintenance control data is transmitted and received to and from the host computer and the portable terminal device via the copying machine.
