Abstract
Abstract A facsimile apparatus has a switch which determines whether or not the facsimile apparatus functions as a remote terminal for remote maintenance. When the facsimile apparatus functions as a remote terminal, it is accessed by the center apparatus so that the center apparatus can read and/or rewrite internal data stored in the facsimile apparatus. If an user does not desire the access, the switch is pushed so that the facsimile does not function as a remote terminal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
A facsimile apparatus comprising: memory means for storing predetermined data; setting means for setting the predetermined data to be in one of a first state and a second state; control means, coupled to said memory means and setting means, for authorizing an access from an exterior of the facsimile apparatus to the predetermined data when the predetermined data are set to be in the first state by said setting means, and for unauthorizing the access to the predetermined data when the predetermined data are set to be in the second state by said setting means; and wherein said setting means further comprises count means for counting a predetermined number of times the access is performed so that said setting means sets the predetermined data to be in the second state after the count means counts the predetermined number of times the access is performed, said control means authorizing the access until the counting means counts the predetermined number of times.
Claim 2
Dependent Claim
160 words
A facsimile apparatus comprising: memory means for storing predetermined data; setting means for setting the predetermined data to be in one of a first state and a second state; control means, coupled to said memory means and setting means, for authorizing an access from an exterior of the facsimile apparatus to the predetermined data when the predetermined data are set to be in the first state by said setting means, and for unauthorizing the access to the predetermined data when the predetermined data are set to be in the second state by said setting means; and wherein said setting means further comprises count means for counting a predetermined number of times the access is performed so that said setting means sets the predetermined data to be in the second state after the count means counts the predetermined number of times the access is performed, said control means authorizing the access until the counting means counts the predetermined number of times.
Claim 3
Dependent Claim
30 words
A facsimile apparatus according to claim 1, wherein said setting means sets the predetermined data to be in the second state after the access to the predetermined data is finished.
Claim 4
Dependent Claim
87 words
A facsimile apparatus according to claim 1, wherein said setting means further comprises first clock means for clocking a predetermined time period since said setting means sets the predetermined data to be in the first state so that said setting means sets the predetermined data to be in the second state after the first clock means clocks the predetermined time period, said control means authorizing the access only during the predetermined time period since said setting means sets the predetermined data to be in the first state.
Claim 5
Dependent Claim
83 words
A facsimile apparatus according to claim 1, wherein said setting means further comprises a second clock means for clocking present time so that said setting means sets the predetermined data to be in the first state when the second clock means clocks a start time and sets the predetermined data to be in the second state when the second clock means clocks an end time, said control means authorizing the access during a time period from the start time to the end time.
Claim 6
Dependent Claim
40 words
A facsimile apparatus according to claim 1, wherein the predetermined data comprises a plurality of data and said setting means sets each data of the plurality of data to be in one of the first state and the second state.
Claim 7
Dependent Claim
50 words
A facsimile apparatus according to claim 1, wherein said setting means further sets each data of a plurality of data to be in a predetermined initial state the moment electricity is supplied to said facsimile apparatus, the predetermined initial state being one of the first state and the second state.
Claim 8
Dependent Claim
50 words
A facsimile apparatus according to claim 1, wherein said facsimile apparatus further comprises controller identification means for identifying controllers who perform the access to the predetermined data, said control means authorizing an access to the predetermined data when a controller of the access is identified by said controller identification means.
Claim 9
Dependent Claim
71 words
A facsimile apparatus according to claim 7, wherein said controller identification means further comprises grade means for grading each of the controllers and each data of a plurality of data as having a predetermined level, respectively, control means authorizing the access to each data of a plurality of data when a grade of the controller of the access is higher than a grade of each data of a plurality of data.
