A monitor system using a table tap as defined in claim 7, wherein said base station possesses a table on which the identification code specific to the table tap transmitted from the table tap is associated with the judgement conditions set on the table tap. 9. A monitor system using a table tap as defined in claim 8, wherein the name of the user of the table tap and where to make contact with the user are used as the identification code specific to the table tap, which is included in the table of the base station. 10. A monitor system using a table tap as defined in claim 8, wherein the production code of the table tap is used as the identification code specific to the table tap, which is included in the table of the base station. 11. A monitor system using a table tap as defined in claim 10, wherein said base station possesses a table on which the production code specific to the table tap is associated with the name of the user of the table tap and where to make contact with the user. 12. A monitor system using a table tap as defined in claim 7, wherein said base station searches the table for the name of the user of the table tap and where to make contact with the user, on the basis of the identification code of the table tap transmitted from the table tap, and displays these data on the base station terminal and, further, displays the contents of the satisfied judgement condition on the base station terminal, on the basis of the judgement condition transmitted from the table tap. 13. A monitor system using a table tap as defined in claim 7 wherein: said table tap and said base station are provided with speakers and microphones, respectively, to enable conversation between the base station and the table tap; and when one of the judgement conditions set on the table tap from the base station is satisfied, said table tap transmits its identification code and the satisfied judgement condition as a modem signal to the base station and, thereafter, the table tap changes the modem signal to an audio signal to enable conversation with the base station using the speakers and the microphones. 14. A monitor system using a table tap as defined in claim 5, wherein said base station displays, on a base station terminal, the contents of the judgement conditions set on the table tap. 15. A monitor system using a table tap as defined in claim 5, wherein said table tap further comprises a display unit for displaying the judgement conditions set from the base station. 16. A monitor system using a table tap as defined in claim 5, wherein said table tap further comprises a facsimile for outputting the judgement conditions set by the base station, as a facsimile signal, through the communication line to the outside. 17. A monitor system using a table tap as defined in claim 5, wherein said table tap further comprises: a speaker; and audio notification means for outputting the set judgement conditions as an audio signal to the speaker. 18. A monitor system using a table tap as defined in claim 5, wherein said base station automatically sets a set time and a set value of electric power which are parameters required to set the judgement condition, on the base tap, according to the season. 19. A monitor system using a table tap as defined in claim 5, wherein said base station automatically sets a set time and a set value of electric power which are parameters required to set the judgement condition, on the base tap, according to the weather. 20. A monitor system using a table tap as defined in claim 4, wherein said table tap and said base station are provided with speakers and microphones, respectively, to enable conversation between the table tap and the base station. 21. A monitor system using a table
