Abstract

PROBLEM TO BE SOLVED: To easily stop the transmission of undesirable telephone number information by performing control so that a terminal discrimination signal is not automatically sent out when a mode wherein a caller's telephone number is not reported is selected. SOLUTION: An operator can make various settings and instructions by pressing a key group (KEY) 8 and previously sets the telephone number of the equipment, whether or not a header is sent at the time of transmission, whether or not the telephone number is reported, a control signal added to a termination-side telephone number for use of the telephone number information service, etc. The setting contents are stored and held in a RAM 3 and can be confirmed on a display part (LCD) 7. Further, whether or not the telephone number is reported can be instructed with a KEY 8 each time transmission is performed. Then when the mode wherein the origination-side telephone number is not reported at the time of call is selected, the equipment is so controlled automatically that TIS and CIG are not sent and the transmission header is not sent irrelevantly to the settings of the equipment.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for connecting to a network having a function of selecting whether or not to notify a called party of a telephone number of a calling party.

[0002]

2. Description of the Related Art Conventionally, in a pre-communication procedure for facsimile, a transmission terminal identification signal (TS
In the facsimile machine that transmits I) and the calling terminal identification signal (CIG) at the time of sending the transmission command,
If there is telephone number information set in the device in advance, it is always transmitted in the pre-communication procedure.

Further, in a facsimile machine which converts telephone number information into image data and adds it as a header to the image data of an original to be sent, if the apparatus is set to add a header, it will be sent every time. The header was always added and sent.

[0004]

However, when the network has a service for notifying the receiving side of the telephone number of the calling side and whether or not to give the notification can be selected for each communication, the facsimile apparatus of the conventional example described above is used. Even if a mode in which the number is not notified is selected and communication is performed, the telephone number information is notified to the called side by TSI or CIG, and the original purpose cannot be sufficiently satisfied. Then, in order to avoid this, there is a problem that it is necessary to check the setting of the apparatus each time a call is made and to change the setting of the apparatus unless the telephone number information is transmitted.

Further, in a device which is set to send a transmission header in which telephone number information is converted into image data, similarly, there is a problem that it is necessary to change the setting of the device.

An object of the present invention is to provide a facsimile apparatus which can easily stop the transmission of inconvenient telephone number information in the pre-communication procedure.

[0007]

According to the present invention, when a mode in which a calling telephone number is not notified at the time of calling is selected, TSI or CIG is not automatically transmitted regardless of the setting of the device. Further, by controlling the apparatus so as not to send the transmission header, it is possible to provide a convenient facsimile apparatus which does not need to change the setting of the apparatus each time the telephone number notification mode is changed.
