BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal apparatus such as a facsimile apparatus that effectively uses a dial-in service.
[0002]
[Prior art]
In the past, companies have installed private branch exchanges (PBX) and used dial-in services. Currently, however, a facsimile machine incorporating a dial-in processing circuit has been developed. Different telephone numbers are assigned to each of the facsimile apparatus itself and the telephone by connecting the telephone.
[0003]
Recently, a modem dial-in service has been used as one of the pre-communication information notification services, and if this service is used, the dial-in number can be determined before receiving the call signal. Sometimes, you can call a designated phone directly.
FIG. 6 is a diagram showing the basic operation of this service. Note that (1) to (9) in the figure are numbers assigned to each operation, and the information receiving terminal refers to a communication terminal device such as a telephone or a facsimile machine that can use this service. .
[0004]
When a subscriber line exchange makes a call to an information receiving terminal for which a service contract has been made in advance from another communication terminal device, the subscriber line switch sets the polarities of subscriber lines L1 and L2 (telephone lines) that are lines on the receiving terminal side The information receiving terminal activation signal is transmitted ((2)). On the other hand, when the receiving terminal side is ready to receive information such as dial-in numbers (hereinafter referred to as “information etc.”), it closes the DC circuit in the terminal (DC loop closed) and sends a primary response signal. Send out ((3)). When the exchange side determines the primary response signal from the DC resistance value, it transmits information and the like to the receiving terminal side by means of a modem signal (4). When receiving the modem signal such as information, the receiving terminal side sends a reception completion signal by opening the DC circuit (DC loop open) (5), and the exchange side sends the information signal etc. When a reception completion signal is received within time t, a call signal is sent out (6).
[0005]
At this time, since the information receiving terminal detects a dial-in number in advance, a line is connected in advance to a telephone or the like to which the number is assigned, and a ringing sound is directly generated to prompt the user to respond. ing.
On the other hand, when the telephone responds by picking up the handset, the information receiving terminal detects this, closes the DC circuit again (DC loop closed), and sends a secondary response signal (▲ 7). After that, when the polarity is reversed, a call can be made between the answering telephone and the caller ((8), (9)).
[0006]
The information transmitted by the modem signal includes the number display service source telephone number and the like in addition to the dial-in number (called number information). In the number display service, if the caller telephone number cannot be notified in addition to the caller telephone number, the reason is notified. For example, the reason may be that non-notification is designated by an operation before dialing a telephone number ("184" is dialed) or that a call is made from a public telephone.
[0007]
[Problems to be solved by the invention]
However, in the communication terminal device using the conventional dial-in service, when the function setting of this device is changed from another remote device, the contents of the signal sent after connecting the line once The remote device side always had to pay communication charges.
[0008]
For example, when this apparatus is a facsimile apparatus, when changing the standby mode from the telephone standby mode to the facsimile reception standby mode, an operation such as making a call from a telephone outside the office and sending a tone signal is required. .
Also, in other remote devices, when image data stored in the memory of this device is taken out (this function is called “remote reception”), it is necessary to connect a line once. It took no change.
[0009]
The present invention has been made in view of such circumstances, and by using a dial-in service, before connecting a line, a process corresponding to a dial-in number is executed, and An object of the present invention is to provide a communication terminal apparatus that does not incur communication charges.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a communication terminal apparatus according to claim 1 of the present invention comprises a detecting means for detecting a dial-in number sent from an exchange, and a dial-in number detected by the detecting means in advance. A control means for executing a pre-registered process corresponding to the registered dial-in number after disconnecting the line when it matches the registered dial-in number; and an accumulating means for storing information to be communicated comprising a said control means, as the processing previously registered, the destination which is previously registered in correspondence to the dial-in number was the registration, and transmits the information stored in said storage means.
[0011]
This communication terminal is designated based on the dial-in number sent after the call signal, except when using a modem dial-in service for detecting the dial-in number before the call signal is sent. It can also be applied to the case of using a conventional dial-in service that sends an extension call signal to a telephone or the like. For this reason, it is necessary to make a contract for these services in advance and to provide functions corresponding to each service.
[0012]
In this communication terminal device, since the connection of the line is disconnected before executing the pre-registered process, the device itself or the connected telephone does not respond to the call, Does not incur communication charges.
In addition, this makes it possible to transmit the stored information to other communication terminal devices simply by remotely calling the dial-in number of the communication terminal device.
[0013]
The communication terminal device according to claim 2 is configured to detect a dial-in number sent from an exchange, and when the dial-in number detected by the detecting unit matches a dial-in number registered in advance. A control means for executing a process registered in advance corresponding to the registered dial-in number after disconnecting the line; and an accumulating means for accumulating information to be communicated, wherein the detecting means further comprises an exchange The control means detects the information stored in the storage means as the source of the detected source telephone number as a pre-registered process. It is characterized by transmitting.
Here, in order to detect the source telephone number sent before the call signal, it is necessary to contract for the number display service, and it is necessary to detect the dial-in number before the call signal. Therefore, the dial-in service is limited to the modem dial-in service. As described above, when a plurality of services are contracted as the pre-communication information notification service, information about a plurality of services is simultaneously sent from the exchange (see the circled numeral 4 in the drawing of FIG. 6).
[0014]
In this communication terminal device, when the detected dial-in number matches the dial-in number registered in advance, the stored information is transmitted to the detected caller telephone number after disconnecting the line connection. Remote reception can be performed without incurring communication charges.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating an example of a configuration of a communication terminal device. Here, the configuration of the facsimile apparatus F is shown as a communication terminal apparatus. However, the present invention is not limited to this, and any apparatus having a dial-in function may be used. For example, a plurality of telephones may be connected. A telephone having an exchange connection function or a personal computer with a communication function may be used.
[0016]
A case will be described below where the dial-in function has the function corresponding to the modem dial-in service described with reference to FIG.
In the figure, 1 is a control means comprising a CPU or the like, a main control unit for controlling the following parts, 2 sends a dial signal to the telephone line L, controls the closing and opening of the telephone line L, and NCU also equipped with polarity reversal detection function, 3 is a modem for modulating and demodulating signals for facsimile communication, 4 is an image memory for storing encoded image data, and 5 is necessary for controlling the apparatus F A RAM for storing various data, a ROM 6 for storing a control program in advance, a display unit 7 composed of a liquid crystal screen and LED lamps, an operation unit 8 composed of various switches, 9 A reading unit that reads image data from a set original, 10 is a recording unit that prints out an image received by facsimile or an image read from the reading unit 9 on a preset recording paper, and 11 is a plurality (n units). Is connected to a communication terminal device such as telephones T1 to Tn, and based on the dial-in number, the connection of the telephone line L is switched to either the facsimile apparatus F itself or a plurality of telephones T1 to Tn. In-processing section.
[0017]
The facsimile apparatus F encodes an image of a document read by the reading unit 9, temporarily stores it in the image memory 4, sequentially reads it, performs facsimile transmission via the modem 3 and NCU 2, and other communication. Image data received by facsimile from the terminal device via the telephone line L is sequentially stored in the image memory 4, decoded while being read out, and recorded by the recording unit 10.
[0018]
Further, if the image read from the reading unit 9 is stored in the image memory 4 constituting the storage means in advance, in response to a remote transmission request from another device through the telephone line L, It also has an image transmission function (remote transmission function).
Further, in this facsimile apparatus F, the function of the modem dial-in service described with reference to FIG. 6 is performed by the main control unit 1, the NCU 2, and the modem 3, which constitute dial-in number detecting means. Yes. This means is not limited to being built in the facsimile apparatus F, and may be externally attached as an adapter.
[0019]
When the main control unit 1 detects a dial-in number sent from the exchange through the telephone line L, the main control unit 1 uses the dial-in processing unit 11 to select either the device F itself or the telephones T1 to Tn based on this number. Is connected to the telephone line L. When the call signal is sent, if the facsimile apparatus F or the telephones T1 to Tn responds to the call signal by automatic incoming call or picking up the handset, the facsimile communication or the telephone call is started.
[0020]
Further, the main control unit 1 detects the dial-in number sent from the exchange, and when the detected dial-in number matches the dial-in number registered in advance, the connection switching by the dial-in processing unit 11 is performed. Otherwise, after the connection of the line L is cut off so as not to receive the call signal, processing registered in advance corresponding to the registered dial-in number is executed.
[0021]
Here, the pre-registered processing includes a change in standby mode and other function settings for the apparatus F, as well as remote transmission, and the processing contents are set and registered in the RAM 5 in advance. When the main control unit 1 detects the dial-in number, the main control unit 1 refers to the RAM 5 and determines execution of the process.
For example, even if this facsimile apparatus F is provided with an attached telephone and the user forgets to switch the standby mode from the telephone standby mode to the facsimile reception standby mode when going out, the apparatus F is predetermined. The standby mode can be switched remotely simply by making a phone call from a location outside the office (such as work). Therefore, there is no need for an operation for transmitting a tone signal as in the prior art. Further, since the line L is disconnected before calling (before sending the calling signal), there is no burden of communication charges.
[0022]
Further, when the main control unit 1 detects the dial-in number, as a pre-registered process, the main control unit 1 matches the detected number and displays an image on the other party registered in advance corresponding to the registered dial-in number. Information stored in the memory 4 can also be transmitted. As a result, it is possible to instruct memory transmission to another communication terminal device simply by making a remote call to this facsimile device F.
[0023]
Further, in the case of remote transmission, the facsimile apparatus F also detects the caller telephone number sent before the call signal with the contract of the number display service. When the modem dial-in service and the number display service are contracted as pre-communication information notification services, the dial-in number and the caller telephone number are sent simultaneously as information etc. from the exchange by modem signals. (See (4) in FIG. 6). Accordingly, the main control unit 1, the NCU 2, and the modem 3 also constitute a caller telephone number detection unit.
[0024]
The main control unit 1 detects the dial-in number, and when the detected dial-in number matches the dial-in number registered in advance, the main control unit 1 disconnects the line L and then detects the outgoing call detected at the same time as the dial-in number. The original telephone number is called and the information stored in the image memory 4 is transmitted. Thereby, at the transmission source, remote reception can be executed without incurring a communication fee.
[0025]
FIG. 2 is a flowchart (steps 100 to 109) showing the operation of the facsimile apparatus F described above. Here, the function for executing the processing registered in advance is called a macro function, and the caller telephone number is detected together with the dial-in number (102).
When the facsimile apparatus F receives the information receiving terminal activation signal ((2) in FIG. 6) (100), it sends a primary response signal ((3) in FIG. 6) (101), and dial-in number and source A telephone number (information, etc.) ((4) in FIG. 6) is detected (102). It is determined whether the detected dial-in number is for the macro function (103). If the detected dial-in number is not for the macro function, a reception completion signal ((5) in FIG. 6) is sent in accordance with the operation of the normal modem dial-in service. Sending out (104), connecting either the facsimile apparatus F itself corresponding to the dial-in number or the telephones T1 to Tn, and receiving a call signal ((6) in FIG. 6) (105). On the other hand, if the facsimile apparatus F itself (NCU2) or the telephones T1 to Tn receives a call (106), communication and telephone conversation can be started as shown in FIG.
[0026]
On the other hand, if the detected dial-in number is for the macro function, after waiting for a predetermined time t (for example, 2 seconds) from detection of the dial-in number (107), the modem dial-in service operation is stopped and the DC loop is interrupted. (108). This predetermined time t is a waiting time for the reception completion signal on the exchange side. If the exchange does not detect the reception completion signal during this time t, the operation shifts to the line L disconnection operation, and (6) in FIG. ▼ Do not perform the following steps.
[0027]
Since the facsimile apparatus F side cuts the DC loop after the time t has elapsed (108), the exchange side does not determine this as a reception completion signal. In this case, since it is a contract with the number display service, if the waiting time of the reception completion signal in the exchange is different between both services, it is necessary to break the DC loop after the longer time has elapsed. There is. Then, after breaking the DC loop, the macro function registered corresponding to the dial-in number is executed (109).
[0028]
Next, a method for determining whether or not the dial-in number is for the macro function (103 in FIG. 2) will be described with reference to FIG. 3A, 3B, and 3C are configuration examples of the tables 51, 52, and 53 stored in the RAM 5 in advance.
In the macro table 51 shown in FIG. 3 (a), dial-in numbers for macro functions are registered. When the same dial-in number as the number stored therein is detected, the macro table 51 is designated in advance. Execute macro function.
[0029]
If this table 51 is used, the image data stored in the image memory 4 is transmitted (remote transmission) or the reception mode is changed only when a call is made to the number registered here. be able to. In addition, here, it is possible to register image transmission as well as the case of transmission to the transmission source and the case of broadcast transmission.
When registering remote transmission, the box number in the image memory 4 storing the image data to be transmitted may be registered in correspondence with the dial-in number.
[0030]
In the transmission destination number table 52 shown in FIG. 3B, transmission destination telephone numbers are registered. In the macro table 51 of (a), since “image transmission” is registered corresponding to the dial-in number “001”, the telephone registered in the transmission destination number table 52 when this number is detected. The image data stored in the image memory 4 is transmitted to the number. When a plurality of “image transmissions” can be registered in the macro function designation of the macro table 51, the transmission destination telephone number is associated with each of the dial-in numbers to be designated in the transmission destination number table 52. You may make it register.
[0031]
In the broadcast transmission destination number table 53 shown in FIG. 3C, a plurality of transmission destination telephone numbers are registered. In the macro table 51 of (a), “image transmission (broadcast)” is registered corresponding to the dial-in number “003”, and when this number is detected, the broadcast transmission destination number table 53 is detected. The image data stored in the image memory 4 is sequentially transmitted to each of the telephone numbers registered in. When a plurality of “image transmission (broadcast)” can be registered in the macro function designation of the macro table 51, the broadcast transmission destination number table 53 is associated with each dial-in number to be designated. A plurality of broadcast destination telephone numbers may be registered one by one.
[0032]
Next, FIG. 4 is a flowchart (steps 200 to 209) showing an operation when the macro function is executed using the tables 51 to 53 shown in FIG.
The detected dial-in number is for the macro function (registered in the macro table 51). When executing the macro function (109 in FIG. 2), the macro table 51 refers to the macro function designation corresponding to the dial-in number (200). ).
[0033]
If the designation is image transmission (Y in 201), individual transmission that is not broadcast transmission (N in 202), and transmission to the transmission source (Y in 203), the image in the image memory 4 is Transmission is made to the caller telephone number (204), and if not to the caller (N in 203), the image in the image memory 4 is sent to the telephone number in the transmission destination number table 52 (205). . If the transmission is broadcast (Y in 202), the images in the image memory 4 are sequentially transmitted to the telephone numbers in the broadcast transmission destination number table 53 (206).
[0034]
In addition, although the example which made the other party which transmits an image a telephone number was shown above, this invention is not limited to this, You may make designation | designated of an other party into an e-mail address. In this case, a call is made to the provider, and the mail address registered in the transmission destination number table 52 or the broadcast transmission destination table 53 or the mail address of the transmission source included in the information ((4) in FIG. 6) is sent. The data in the image memory 4 is transmitted as mail.
[0035]
When the macro function designation is not image transmission (N of 201), the designation is a change of the reception mode, so the current reception mode is referred to (207), and if the current reception mode is the home mode, the absence The mode is set (208), and if it is the absent mode, the home mode is set (209). Normally, a dial-in function is executed in the home mode, and a facsimile reception or answering machine function is executed in the absence mode.
[0036]
The case where the modem dial-in service for detecting the dial-in number is used before the call signal is transmitted as the dial-in function has been described above. However, the present invention is transmitted after the call signal. The present invention is also applicable to the case of using a conventional dial-in service that sends an extension call signal to a designated telephone or the like based on a dial-in number.
[0037]
FIG. 5 is a diagram showing the basic operation of this service. Here, a case where the communication terminal apparatus having a dial-in function is the facsimile apparatus F having the configuration shown in FIG. 1 will be described. Note that (1) to (8) in the figure are numbers assigned to the respective operations.
The subscriber line exchange inverts the polarities of the subscriber lines L1 and L2 (telephone line L) when a call is made from the other communication terminal apparatus to the apparatus F with which the service contract has been made in advance ((1)). Then, a call signal is transmitted ((2)). On the other hand, when the device F side becomes ready to receive the extension designation signal (dial-in number), the DC circuit in the device F is closed (DC loop closed), and a primary response signal is sent out (▲ 3 ▼). When the exchange side determines the primary response signal from the DC resistance value, it transmits an extension designation signal to the apparatus F side by the PB signal (push button signal) (4). When the device F side receives the PB signal, it opens the DC circuit (opens the DC loop) and sends an extension designation reception completion signal (5). At the same time, it decodes the PB signal and designates it. The device F itself or the telephones T1 to Tn to which the extension number is assigned is connected to the line L, an extension call signal is transmitted, a ringing tone is generated, and the user is prompted to respond. On the other hand, when receiving the extension designation reception completion signal within time t1 (for example, 2 seconds) after sending the extension designation signal, the exchange side sends a ringing tone to the calling side.
[0038]
In the facsimile apparatus F, when the response of the called apparatus F itself or the telephones T1 to Tn is detected, the DC circuit is closed again (DC loop closed), and a secondary response signal is sent ((6)). When the polarity is reversed, communication or a telephone call can be performed between the responding facsimile apparatus F or telephones T1 to Tn and the caller ((7), (8)).
[0039]
In order to fulfill the functions as described above, the dial-in processing unit 11 of the facsimile apparatus F is provided with means for detecting a PB signal and means for generating an extension call signal in addition to switching control of connection to the line L.
The main control unit 1 detects an extension designation signal (dial-in number) sent from the exchange, and when the detected dial-in number matches a previously registered dial-in number, the case of modem dial-in service Similarly to the above, connection switching by the dial-in processing unit 11 is not performed, and after the connection of the line L is disconnected after the elapse of time t1, processing registered in advance corresponding to the registered dial-in number is executed.
[0040]
As the pre-registered processing, the image stored in the image memory 4 can be transmitted to the other party registered corresponding to the dial-in number registered in advance, matching the detected dial-in number. . If the number display service function is not provided, the source telephone number cannot be detected by a modem signal. However, if the source telephone number is registered in advance as a destination corresponding to the dial-in number, The image stored in the image memory 4 can be transmitted to the transmission source.
[0041]
【The invention's effect】
As can be understood from the above description, when the dial-in number sent from the exchange matches the dial-in number registered in advance, the communication terminal device according to claim 1 and claim 2 of the present invention A process registered in advance corresponding to the dial-in number is automatically executed. Therefore, the transmission source can remotely operate the apparatus only by making a call to a predetermined dial-in number of the apparatus. Further, the line is disconnected before the response is made, and the pre-registered processing is executed, so that the transmission source does not bear a communication fee.
[0042]
In particular, in claim 1 , when the detected dial-in number matches the dial-in number registered in advance, information stored in advance is transmitted to the destination registered corresponding to the dial-in number. The transmission source can instruct remote transmission to another communication terminal device without incurring a communication fee. Further, in claim 2 , when the detected dial-in number matches the pre-registered dial-in number, the information stored in advance is transmitted to the detected source telephone number. Remote reception can be executed without incurring communication charges.
