Abstract
Abstract A facsimile machine has a remote control operation mode in which functions in the facsimile machine are remotely activated based on an ID code supplied from a remote telephone terminal. The facsimile machine includes a memory which stores the ID code, and controller a having a first function for determining whether or not an erroneous ID code which differs from the ID code stored in the memory is supplied from the remote telephone terminal, a second function for counting a number of times that the erroneous ID code is supplied from the remote telephone terminal based on a first determination result obtained by the first function, and a third function for determining whether or not the remote control operation mode can be activated based on the number of times counted by the second function. The remote control operation mode is prohibited from being used in the facsimile machine when the third function has determined that the remote control operation mode cannot be activated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
A communication apparatus having a remote control operation mode in which functions in said communication apparatus are remotely activated based on a predetermined code supplied from an external terminal, said communication apparatus comprising: storage means for storing the code; first determination means, coupled to said storage means, for determining whether or not an erroneous code which differs from the code stored in said storage means is supplied from the external terminal; counter means, coupled to said first determination means, for counting a number of times that the erroneous code is supplied from the external terminal based on a first determination result obtained by said first determination means; second determination means, coupled to said counter means, for determining whether or not the remote control operation mode can be activated based on the number of times counted by said counter means, and means, coupled to said counter means, for initializing said counter means when a correct code data which is equal to the code data stored in said storage means is supplied from the external terminal, wherein the remote control operation mode is prohibited from being used in said communication apparatus when said second determination means has determined that the remote control operation mode cannot be activated.
Claim 2
Dependent Claim
205 words
A communication apparatus having a remote control operation mode in which functions in said communication apparatus are remotely activated based on a predetermined code supplied from an external terminal, said communication apparatus comprising: storage means for storing the code; first determination means, coupled to said storage means, for determining whether or not an erroneous code which differs from the code stored in said storage means is supplied from the external terminal; counter means, coupled to said first determination means, for counting a number of times that the erroneous code is supplied from the external terminal based on a first determination result obtained by said first determination means; second determination means, coupled to said counter means, for determining whether or not the remote control operation mode can be activated based on the number of times counted by said counter means, and means, coupled to said counter means, for initializing said counter means when a correct code data which is equal to the code data stored in said storage means is supplied from the external terminal, wherein the remote control operation mode is prohibited from being used in said communication apparatus when said second determination means has determined that the remote control operation mode cannot be activated.
Claim 3
Dependent Claim
45 words
A communication apparatus as claimed in claim 1, wherein said second determination means has means for determining that the remote control operation mode cannot be activated when the number of times obtained by said counter means is greater than or equal to a predetermined number.
Claim 4
Dependent Claim
16 words
A communication apparatus as claimed in claim 1, wherein said communication apparatus is a facsimile machine.
Claim 5
Dependent Claim
37 words
A communication apparatus as claimed in claim 1, wherein said counter means has a counter which is incremented by one when said first determination means determines that the error code data is supplied from the external terminal.
Claim 6
Dependent Claim
44 words
A communication apparatus as claimed in claim 1, further comprising: means, coupled to said second determination means, for informing that the remote control operation mode cannot be activated when said second determination means has determined that the remote control operation mode cannot be activated.
Claim 7
Dependent Claim
27 words
A communication apparatus as claimed in claim 5, wherein said means has display means for displaying a message that the remote control operation mode cannot be activated.
Claim 8
Dependent Claim
50 words
A communication apparatus as claimed in claim 1, further comprising: reset means, coupled to said counter means, for resetting said counter means at a predetermined initial number when a correct code data which is equal to the code data stored in said storage means is supplied from the external terminal.
Claim 9
Dependent Claim
40 words
A communication apparatus as claimed in claim 1, wherein the number of times that the erroneous code is supplied from the external terminal is maintained in said counter means independently of a number of communications performed by said communication apparatus.
Claim 10
Dependent Claim
230 words
A communication apparatus having a remote control operation mode in which functions in said communication apparatus are remotely activated based on a predetermined code supplied from an external terminal, said communication apparatus comprising: storage means for storing the code; first determination means, coupled to said storage means, for determining whether or not an erroneous code which differs from the code stored in said storage means is supplied from the external terminal; counter means, coupled to said first determination means, for counting a number of times that the erroneous code is supplied from the external terminal based on a result obtained by said first determination means; second determination means, coupled to said counter means, for determining whether or not the remote control operation mode can be activated based on the number of times counted by said counter means; means, coupled to said counter means, for initializing said counter means when a correct code data which is equal to the code data stored in said storage means is supplied from the external terminal; prohibition means coupled to said second determination means, for prohibiting the remote control operation mode from being activated in said communication apparatus when said second determination means has determined that the remote control operation mode cannot be activated, wherein while the remote control operation mode is prohibited from being activated, normal communications can be performed by said communication apparatus.
Claim 11
Dependent Claim
230 words
A communication apparatus having a remote control operation mode in which functions in said communication apparatus are remotely activated based on a predetermined code supplied from an external terminal, said communication apparatus comprising: storage means for storing the code; first determination means, coupled to said storage means, for determining whether or not an erroneous code which differs from the code stored in said storage means is supplied from the external terminal; counter means, coupled to said first determination means, for counting a number of times that the erroneous code is supplied from the external terminal based on a result obtained by said first determination means; second determination means, coupled to said counter means, for determining whether or not the remote control operation mode can be activated based on the number of times counted by said counter means; means, coupled to said counter means, for initializing said counter means when a correct code data which is equal to the code data stored in said storage means is supplied from the external terminal; prohibition means coupled to said second determination means, for prohibiting the remote control operation mode from being activated in said communication apparatus when said second determination means has determined that the remote control operation mode cannot be activated, wherein while the remote control operation mode is prohibited from being activated, normal communications can be performed by said communication apparatus.
