TECHNICAL FIELD OF THE INVENTION
The present invention relates to a communication terminal equipment.
[0002]
[Prior art]
2. Description of the Related Art In recent years, a service of notifying information such as a telephone number of a caller from a switchboard to a communication terminal device on a callee side (caller number notification service) has been put to practical use. For example, in a caller ID notification service in Japan, when a dialing call is made at a calling device, an ID receiving terminal activation signal having a different calling pattern from a general calling signal is transmitted from the exchange to a called device. Is done. Then, after the receiving side device closes the line based on the detection of the ID receiving terminal activation signal, information such as the source telephone number is transmitted from the exchange to the receiving side device as a modem signal. Once the receiving device that has received the source information releases the line, a general call signal is transmitted from the exchange to the receiving device. Then, the communication between the transmission source device and the reception side device is started when the receiving side device closes the line in response to the call signal from the exchange.
[0003]
In the caller ID notification service in the United States, when a dial call is made at a caller device, a call signal is transmitted from the exchange to the receiver device, and during a period in which the intermittent call signal is turned off. Then, the transmission source information is transmitted as a modem signal from the exchange to the destination device. Then, after the receiving side device detects the source information from the exchange, the line is closed in response to the calling signal, so that communication between the transmitting side device and the receiving side device is started.
[0004]
As described above, in the caller ID notification service, information such as the telephone number of the caller is notified to the callee device before communication between the caller device and the callee device is started. Before starting communication with the caller, the side device can recognize the caller's telephone number or the like and display it on the display unit.
[0005]
[Problems to be solved by the invention]
By the way, the above-mentioned transmission source number notification service is not freely available on the receiving side and cannot be used without permission of the transmission source. For example, in Japan, when making a dial call at the caller, if the number "1, 8, 4" is entered before the telephone number of the communication partner, the caller's telephone number will not be notified to the called party. ing. In this way, the sender can arbitrarily select whether to refuse to use the notification service on the receiving side.
[0006]
However, for example, when the transmission source is a facsimile machine, information such as the telephone number of the transmission source is transmitted to the receiving side as part of the image data. This transmission source information is added to the transmission image data of each page when transmitting the image data at the transmission source. On the receiving side receiving the image data, the transmission source information is recorded on the recording paper. Is printed on the upper end of the printer. For this reason, the receiving side is notified of the telephone number of the caller.
[0007]
In addition, among various facsimile control procedure signals transmitted from the transmission source to the reception side during facsimile communication, there are control procedure signals containing information such as the telephone number of the transmission source. Therefore, the control procedure signal containing the transmission source information is transmitted from the transmission source to the receiving side, so that the receiving side is notified of the telephone number of the transmission source.
[0008]
In this way, even if the notification service is refused to be used for transmission and the notification service is not used by the called party, the sender information is eventually notified to the called party, The operation of refusing the use of the notification service becomes meaningless.
[0009]
The present invention has been made to solve the above-described problem, and an object of the present invention is to prevent the notification of the source information from being notified to the called party when the notification service is not used by the called party. It is to provide a communication terminal equipment as possible.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the communication terminal apparatus according to the first aspect of the present invention, it is determined whether or not the service of notifying the source information from the exchange to the called side is refused to be used on the called side. Means, when the notification service is denied to be used based on the judgment of the judgment means, the notification service is used so that the source information is not included in the control procedure signal transmitted to the called side. Control means for transmitting, to the exchange, a dial signal intended to refuse the call, together with a dial signal corresponding to the telephone number of the called party , wherein the control means uses the notification service based on the judgment of the judging means. In the case of refusing the transmission, the control is performed so that the information of the source telephone number is not included in the NSS signal transmitted to the receiving side .
[0012]
According to the invention of the communication terminal device of the second aspect, the judgment means for judging whether or not the service of notifying the source information from the exchange to the called side is refused to be used on the called side; When the notification service is refused to be used based on the facsimile control procedure signal transmitted to the receiving side, the source information should not be included in the facsimile control procedure signal and the source information should not be added to the transmission image data. Control means for transmitting a dial signal intended to refuse to use the notification service to the exchange together with a dial signal corresponding to the telephone number of the called party , wherein the control means determines When the notification service is refused to be used based on the information, it is controlled not to add the sender information in the transmitted image data and to add the communication date / time and page number information. It is intended to.
[0013]
Therefore, the first and second aspects of the invention have the following operations.
[0014]
According to the first aspect of the invention, when the notification service is refused to be used on the receiving side, the source information is not included in the control procedure signal transmitted to the receiving side. For this reason, when the notification service is prevented from being used by the called side, the called side is not notified of the source information.
[0015]
According to the invention of claim 2 , when the notification service is refused to be used on the receiving side, the facsimile control procedure signal transmitted to the receiving side does not include the transmission source information and the transmission image data. Sender information is not added inside. For this reason, when the notification service is prevented from being used by the called side, the called side is not notified of the source information.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment in which the present invention is embodied in a facsimile machine will be described with reference to the drawings.
FIG. 1 shows a circuit configuration of the facsimile apparatus of this embodiment. A CPU (central processing unit) 1 controls the operation of the entire facsimile machine. The ROM (read only memory) 2 stores various programs and the like necessary for the CPU 1 to perform control. A RAM (random access memory) 3 temporarily stores various information such as data necessary for the arithmetic processing of the CPU 1 and transmission / reception image data. In the present embodiment, the CPU 7, the ROM 8, and the RAM 9 constitute a determination unit and a control unit.
[0017]
The NCU (network control unit) 4 has a function of controlling connection with a telephone line, transmitting a dial pulse corresponding to a telephone number input from a key operation unit 8 described later, and the like. The modem 5 modulates and demodulates transmission / reception data and transmits a push tone signal corresponding to the telephone number input from the key operation unit 8. The modem 5 also has a function of generating and detecting various facsimile control procedure signals transmitted / received to / from a communication partner during facsimile communication.
[0018]
The reading unit 6 is for reading an image on a document, and the recording unit 7 is for printing on recording paper based on received image data and the like. The key operation unit 8 includes various operation keys such as a ten key 8a for inputting a telephone number and the like, a start key 8b for starting facsimile communication, and a setting key 8c. The setting key 8c is used to set whether or not to refuse to use the source number notification service on the communication partner, that is, on the called side, when starting facsimile communication. In other words, the setting key 8c is for setting whether or not to prevent the receiving side from using the notification service. The display unit 9 displays various information such as the input telephone number.
[0019]
Next, the operation of the facsimile apparatus configured as described above will be described.
When the facsimile apparatus is the transmission source, the operations shown in the flowcharts of FIGS. 2 to 4 are performed under the control of the CPU 1. In this flowchart, the receiving-side apparatus called by the facsimile apparatus of the present embodiment can receive the source number notification service.
[0020]
First, as shown in FIG. 2, in a communication standby state, it is determined whether or not a telephone number of a communication partner has been input (step S1). The input of the telephone number is performed by operating the ten keys 8a of the key operation unit 8 or one-touch dial keys (not shown). The telephone number can also be input by inputting a pre-registered abbreviated number using the numeric keypad 8a following the operation of a not-shown abbreviated key.
[0021]
When the telephone number is input, it is determined whether the setting key 8c has been turned on and whether the start key 8b has been turned on (steps S2, S3). Here, if the start key 8b is turned on while the setting key 8c is off, a setting is made to permit the use of the caller ID notification service at the communication destination (the called side), and the process proceeds to step S4. If the start key 8b is turned on while the setting key 8c is turned on, a setting is made to refuse the use of the caller ID service on the called side, and the process proceeds to step S4.
[0022]
In step S4, it is determined whether a document for reading is set on a document tray (not shown) of the apparatus based on a detection result of a document detection sensor (not shown). Here, when the original is not set, for example, "Please set the original" is displayed on the display unit 9 in order to prompt the user to set the original (step S5). If a document is set, an image on the document is read by the reading unit 6, and the read image data is stored in the RAM 3 (step S6).
[0023]
When the reading of the original is completed (step S7), after the line with the exchange is closed (step S8), it is determined whether or not a setting to reject the use of the notification service has been made by the setting key 8c (step S8). Step S9). Here, if the setting for rejecting the use of the notification service is not made and the setting for permitting the use is made, a dial signal corresponding to the telephone number previously input is transmitted to the exchange ( Step S10). On the other hand, if the setting is made to reject the use of the notification service, a dial signal corresponding to the input telephone number is transmitted to the exchange after a dial signal corresponding to the number "1, 8, 4" ( Step S11).
[0024]
When the exchange receives the dial signal, the exchange calls the other party (called side) having the telephone number indicated by the dial signal. In this case, if the exchange does not receive a dial signal corresponding to the number “1, 8, 4” from the caller, the exchange determines that use of the caller number notification service is permitted, and Call the called party according to the procedure according to the notification service. Therefore, information such as the originating telephone number is notified from the exchange to the receiving side, and the receiving side can recognize the telephone number of the originating side using this notification service. On the other hand, when the exchange receives the dial signal corresponding to the number “1, 8, 4” from the caller, it determines that the use of the caller ID notification service has been rejected, and And does not notify the called party of information such as the source telephone number. Therefore, the receiving side cannot recognize the source telephone number.
[0025]
Then, as shown in FIG. 3, when the called side responds to the call, facsimile communication with the called side is started. That is, first, a CNG signal (1100 Hz ringing tone) is transmitted from the modem 5 to the receiving side (step S12). Then, following the CED signal (the called terminal identification signal of 2100 Hz) from the receiving side, the DIS signal (digital identification signal), the NSF signal (non-standard function identification signal) and the CSI signal (the called terminal identification signal) are transmitted to the modem. 5, the DCS signal (digital command signal) is transmitted from the modem 5 to the receiving side (step S15).
[0026]
Subsequently, it is determined whether or not a setting for rejecting the use of the notification service has been made by the setting key 8c (step S16). Here, if the setting to reject the use of the notification service is not made, that is, if the setting to permit the use of the service is made, information such as the telephone number of the caller is stored from the modem 5 to the receiving side. The TSI signal (transmitting terminal identification signal) and the NSS signal (non-standard function setting signal) are transmitted (step S17).
[0027]
Each of the TSI signal and the NSS signal has a FIF (Facsimile Information Field). The FIF in the TSI signal contains the data of the source telephone number, and the FIF in the NSS signal can also contain the data of the source telephone number. Therefore, the receiving side can recognize the telephone number of the transmission source based on the reception of the TSI signal and the NSS signal from the transmission source.
[0028]
On the other hand, if it is determined in step S16 that the use of the notification service is to be refused, an NSS signal containing no information such as the telephone number of the caller is transmitted from the modem 5 to the receiving side, and the TSI signal is transmitted. It is not performed (step S18). That is, when the notification service is not used by the receiving side, the TSI signal containing the data of the source telephone number is not transmitted to the receiving side. In addition, information such as the source telephone number is not included in the NSS signal transmitted to the receiving side. Therefore, even if the receiving side receives the NSS signal from the source, it cannot recognize the telephone number of the source.
[0029]
Next, the training signal and the TCF signal (training check signal) are transmitted from the modem 5 to the receiving side, and the modem 5 is trained (adjusted) (step S19). Thereafter, when a CFR signal (reception preparation confirmation signal) is received from the receiving side (step S20), the process proceeds to step S21 in FIG.
[0030]
In step S21, it is determined whether or not a setting for rejecting the use of the notification service has been made by the setting key 8c. Here, if the setting to reject the use of the notification service is not made, the sender information is added to one page of the read image data previously stored in the RAM 3 and the sender information is added. The image data for one page is transmitted to the receiving side (step S22).
[0031]
The source information includes information such as a source telephone number, a source name, a communication date and time, and a page number of transmission image data. The source telephone number and the source name in the source information are input by, for example, predetermined operation keys provided in the key operation unit 8 and registered in the RAM 3 in advance. Then, when reading and transmitting the read image data in the RAM 3 one page at a time, the CPU 1 adds transmission source information to the head of the transmission image data of each page and uses the transmission source information as a part of the image data. Send to called party. Therefore, on the receiving side receiving the image data, when the received image data is printed on the recording paper, the sender information is printed on the upper end of the recording paper. Therefore, the user on the receiving side can recognize the telephone number or the like of the caller by looking at the recording paper.
[0032]
On the other hand, if the setting for rejecting the use of the notification service is made in step S21, the sender information is not added to one page of the read image data previously stored in the RAM 3 without being added. The image data for one page is transmitted to the receiving side (step S23). Therefore, on the receiving side receiving the image data, even if the received image data is printed out on the recording paper, the sender information is not printed on the upper end of the recording paper. For this reason, the user on the receiving side cannot recognize the telephone number or the like of the caller even by looking at the recording paper. In step S23, information other than the information indicating the transmission source, such as the communication date and time and the page number, may be added to the transmission image data.
[0033]
When the transmission of the image data of one page is completed, the process proceeds to step S24, and it is determined whether or not the RAM 3 has the image data of the next page for transmission. Here, when there is image data of the next page, an MPS signal (multi-page signal) is transmitted from the modem 5 to the receiving side, and an MCF signal (message confirmation signal) from the receiving side is transmitted via the modem 5. After the reception, the process returns to the step S21 and shifts to the transmission processing of the image data of the next page. If there is no image data of the next page, an EOP signal (procedure end signal) is transmitted from the modem 5 to the called side, and after the MCF signal from the called side is received via the modem 5, the modem 5 5 transmits a DCN signal (disconnection command signal) to the receiving side, and then the line is opened (step S25).
[0034]
Since the facsimile apparatus of the present embodiment operates as described above, it has the following excellent effects.
(1) When an operation for refusing the use of the caller ID notification service on the called side is performed, the facsimile control procedure signal transmitted to the called side does not include the caller information, and No sender information is added to the data. For this reason, when the notification service is prevented from being used by the receiving side, it is reliably prevented that the source information is notified to the receiving side. Therefore, the advantage that the notification service can be prevented from being used by the called party is fully utilized, and the operation of rejecting the use of the notification service is not meaningless.
[0035]
(2) If the setting of the setting key 8c is set to reject the use of the notification service, the dial signal corresponding to the number "1, 8, 4" is transmitted before the dial signal corresponding to the telephone number of the destination is transmitted. Is sent automatically. For this reason, it is not necessary to additionally input the numbers "1, 8, 4" before the telephone number of the other party, and the input operation of the telephone number when the use of the notification service is to be refused is facilitated.
[0036]
The present invention may be embodied with the following modifications, for example.
(1) Instead of using the setting key 8c to set the refusal to use the notification service, the numbers "1, 8, 4" may be entered using the numeric keypad 8a before entering the telephone number of the other party. In this case, the determination in step S9 becomes unnecessary, and the determination as to whether or not the notification service use is rejected in steps S16 and S21 is made based on whether or not the number “1, 8, 4” has been input. Perform based on
[0037]
(2) As the communication terminal device of the present invention, besides the facsimile device, for example, a personal computer that performs communication using a FAX modem is embodied. In this case, data created on a personal computer or data in a storage medium such as a floppy disk is converted into facsimile communication data and transmitted.
[0040]
【The invention's effect】
As described in detail above, the present invention has the following excellent effects .
[0041]
According to the first aspect of the present invention, when the notification service is not used by the receiving side, the source information is not included in the control procedure signal transmitted to the receiving side, so the source information is notified to the receiving side. Can be reliably prevented.
[0042]
According to the invention of claim 2 , when the notification service is prevented from being used by the receiving side, the source information is not included in the facsimile control procedure signal transmitted to the receiving side, and the source information is not included in the transmission image data. Since no information is added, it is possible to reliably prevent the source information from being notified to the called party.
