Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a telephone.

[0002]

2. Description of the Related Art In recent years, service systems for making reservations for travel tickets and concert tickets using telephone lines have become widespread.

That is, for example, when making a reservation for a travel ticket, when a predetermined signal is input from a destination (user) to a computer of a travel agency (service supply side) via a telephone line, the computer inputs the signal. Travel tickets are booked based on signals.

[0004] To further explain this service system in detail, the computer sends a dial operation procedure announcement to a telephone connected to the computer via a telephone line. Then, the user operates the dial of the telephone according to the instruction of the announcement. That is,
A desired date, a destination, etc. are set according to the operation sequence of the dials, and the computer reserves the ticket desired by the user.

However, this service is limited in that the signal output from the user side is push tone (DTMF). Therefore, if the user's telephone line is a push line, there is no problem, but if it is a dial line, this service may not be available.

That is, when the user's telephone line is a dial line, a dial DIP switch or a slide type DIP switch for switching and setting at least one of dial pulse and push tone is pushed to the telephone being used by pushing from the dial pulse. If a tone changeover switch capable of changing over tones is not provided, the service cannot be received.

Therefore, the user whose line is set to be a dial line must be in a state in which a dial pulse is generated from the telephone every time a reservation call is made to the service supply side. After the connection with the telephone line on the service supply side, the tone changeover switch is turned on or the position of the dip switch is changed over so that a push tone is generated from the telephone. As a result, the telephone becomes compatible with the computer on the service supply side, and the user can receive the service. When service reception ends (on-hook), the push tone automatically returns to the state in which dial pulses are generated.

[0008]

However, in the above prior art, even when the user calls the service supply side to receive the service and is connected to the line of the computer, the operation timing of the tone changeover switch is incorrect. In many cases, there was a risk of trying to receive service without switching the switch.

In this case, there is a problem in that the user's telephone cannot interact with the service's computer, so that the user cannot receive the service. The above problems occur every time the customer tries to receive the reservation service, which is extremely troublesome.

The present invention has been made to solve the above problems, and its object is a communication device capable of reliably transmitting a push tone when a line with a specific destination is connected. To provide.

[0011]

In order to achieve the above object, according to the present invention, a selecting means for selecting one of two outgoing signals of dial pulse and push tone, and a telephone of a specific destination. When it is recognized that the line with the destination stored in the storage means is connected in the state where the storage means for storing the number and the selection means are selected by the side that transmits the dial pulse, a push tone is given. The gist of the invention is to provide a control means for controlling the priority transmission.

[0012]

According to the above construction, when the line is connected to the destination stored in the storage means in the state where the selecting means is selected to the side transmitting the dial pulse, the transmission signal is transmitted by the control means. It automatically switches from dial pulse to push tone.

Also, the reverse switch 12 constitutes a selecting means, and the CPU 6, the ROM 7, etc. constitute a controlling means.

The reverse switch 12 is a switch operated when the outgoing signal output from the telephone line 4 to the exchange side is switched from dial pulse to push tone. When the reverse switch 12 is turned on, the CPU 6 operates the DTMF generating circuit 9a to switch the signal transmitted from the telephone line 4 from dial pulse to push tone. The reverse switch 12 is also operated when the data (telephone number of the service supply side) stored in the RAM 8 is printed out. The copy switch 13 is a switch operated when operating the copy function of the facsimile apparatus 1.

The printing of the telephone number of the service supply side is performed when both the reverse switch 12 and the copy switch 13 are turned on. That is, the CPU 6 is in a state where the handset (not shown) of the attached telephone 5 is on-hook, and after the reverse switch 12 is turned on, the copy switch 13 is passed during a predetermined time (5 seconds in this embodiment).
Only when is turned on, the telephone number of the service supply side stored in the RAM 8 is printed out.

Next, the NCU 3 will be described. A polarity reversal detection circuit 15 is connected between the telephone line 4 and the CML relay 16. This polarity inversion detection circuit 15
Is for detecting polarity reversal when a DC loop (not shown) on the exchange side is closed. Also, the CM
The contact 16 a of the L relay 16 is connected to the CPU 6 of the main controller 2 via the incoming call detection circuit 22.
Further, the contact 16b is connected to the modem 9 of the main controller 2 via the transformer 17a. The other contact 16b is connected to the CPU 6 and the modem 9 via the dial pulse transmission circuit 18.

That is, the CML relay 16 is for selectively connecting the telephone line 4 to the modem 9 side of the main controller 2 and the incoming call detection circuit 22 side. The CML relay 16 has a contact 1 in the device standby state.
The switch 6 is arranged on the 6a side, that is, on the incoming call detection circuit 22 side.

The incoming detection circuit 22 is a CML relay 16
And sent from the exchange side via telephone line 4 1
A 6 Hz ringing signal (ring tone) is detected and the detected signal is output to the CPU 6.

When the CPU 6 detects a calling signal from the telephone line 4 a predetermined number of times via the incoming call detection circuit 22, the CM
The telephone line 4 is controlled by switching the L relay 16 to the contact 16b side.
Is connected to the modem 9 side. Then C
When the PU 6 detects the CNG signal from the calling side, the PU 6 determines that the calling side is a facsimile machine and starts the facsimile operation according to a predetermined facsimile procedure.

The attached telephone 5 is connected to the CPU 6 via an off-hook detection circuit 19. The off-hook detection circuit 19 detects an off-hook state of the attached telephone 5 (a state in which the handset is picked up) and outputs the detection signal to the CPU 6. The attached telephone 5 is connected to the TEL relay 21.

The contact 21a of the TEL relay 21 is connected to the telephone line 4. Also, TEL relay 2
The contact 21b of 1 is connected to the CP via the ringing voltage generation circuit 20.
It is connected to U6. This TEL relay 21 is also the C
Similar to the ML relay 16, the CPU 6 controls switching. In addition, this TEL relay 21
In the device standby state, the switch 21 is switched to the contact 21a side and the connection between the auxiliary telephone 5 and the telephone line 4 is kept closed.

The ringing voltage generating circuit 20 has a function of generating a pseudo bell signal of 16 Hz to ring a ringing bell (not shown) of the attached telephone 5 to notify the user of an incoming call from the calling side. ing. The input side of the transformer 17b is connected to the off-hook detection circuit 19 and the attached telephone 5. On the other hand, the output side of the transformer 17b is connected to the modem 9. And the CPU 6
After the ringing signal is detected a predetermined number of times, the calling side still sends CN
When the G signal is not detected, it is determined that the calling side is the telephone. In this case, the CPU 6 uses the calling voltage generation circuit 20.
Is activated to ring the ringing bell of the attached telephone.

Next, the operation of this embodiment will be described. 2 and 3 are flowcharts showing a control processing routine executed by the CPU 6 of the main controller 2 in this embodiment.

When the processing shifts to this routine, first,
In step 101, based on the detection signal from the off-hook detection circuit 19, it is determined whether or not the handset of the attached telephone 5 is off-hook. If it is determined that it has been taken off-hook, the process proceeds to step 102. At step 102, it is judged if the reverse switch 12 has been turned on. If the reverse switch 12 has not been turned on, that is, if the dial pulse can be generated, the process proceeds to the next step 103. In step 103, it is determined whether or not the dial operation by the user has started.
That is, it is determined whether or not the dial switch 14 has been turned on to connect the line to the other party.

In the next step 104, the order in which the dial switch 14 is turned on in step 103, that is, the telephone number of the other party is stored in the RAM 8. Then, in step 105, it is determined whether or not the polarity has been reversed. That is, based on the output signal from the polarity reversal detection circuit 15, it is determined whether or not the call has arrived at the other party and the polarity has been reversed.

If it is determined that the polarities have been reversed, the process proceeds to step 106. On the other hand, if the polarity is not inverted, the process returns to step 103, and the subsequent processing is repeated. In step 106, the telephone number already stored in the RAM 8 and the step 1
The telephone number stored in 04 is collated.

Then, in the next step 107, it is judged whether or not the collated telephone numbers match.
That is, it is determined whether or not the telephone number stored in step 104 is already stored in the RAM 8. In other words, it is determined whether or not there are two data with the same telephone number. Here, if the telephone number stored in step 104 is already stored in the RAM 8 and it is determined that one is unnecessary, the process proceeds to step 108.

In step 108, the latest telephone number stored in the RAM 8, that is, step 104
The telephone number stored in is deleted from the RAM 8. Then, in step 109, the outgoing signal output from the telephone line 4 is automatically switched from dial pulse to push tone.

Then, in step 110, the signal of the dial switch 14 turned on by the user based on the announcement transmitted from the computer on the service supply side activates the DTMF generating circuit 9a to send it to the destination computer. Sent.

Then, in step 111, it is judged whether or not the service is completed, that is, whether or not the handset is hooked on the basis of the output signal from the off-hook detection circuit 19. Here, when it is determined that the handset is on-hook, the outgoing signal is automatically returned from the push tone to the dial pulse, and the subsequent processing is ended.

On the other hand, in step 107, if the collated telephone numbers do not match, that is, if a telephone number that has not been input before is input this time, the process proceeds to step 112. In step 112, it is determined whether or not the reverse switch 12 has been turned on by the user. If it is determined that the reverse switch 12 has not been turned on by the user,
Control goes to step 113.

In step 113, the latest telephone number stored in the RAM 8, that is, step 1
After the telephone number stored in 04 is erased, the process proceeds to step 111 and the subsequent processing is repeated. That is, when the telephone number connected to the line and the telephone number stored in the RAM 8 do not match and the reverse switch 12 is not turned on, it is determined that the telephone is in a normal call state.

On the other hand, when it is determined in step 112 that the reverse switch 12 is turned on, the latest telephone number is not erased and the process proceeds to step 109 and the subsequent processing is performed.

As described above, according to the facsimile apparatus 1 of this embodiment, when receiving a reservation service for a travel ticket or the like using a telephone line, first, a dial pulse is generated to establish a line with the service supply side. Are connected.

In this state, by inputting the telephone number of the service supplying side who wants to receive the service, the line with the computer of the service supplying side is connected. At the same time, the telephone number of the service supply side stored in the RAM 8 is compared with the telephone number of the service supply side to which the current line is connected. That is, the telephone number of the service supply side to which the line is currently connected is already R
If it is stored in AM8, the same telephone number is not stored in RAM8 again.

In this embodiment, as this collating method, first, it is determined whether or not the first digit numbers of the telephone numbers to be collated match. Then, the next second digit number is collated only with respect to the telephone number having the same first digit number, and the next digit is collated also only with the telephone number having the same digit number. By repeating the same operation thereafter, the unmatched telephone numbers are sequentially eliminated. Therefore, it is possible to significantly reduce the time required for the collation as compared with the case of collating all the digits at once.

Further, the currently connected telephone number of the service supply side and the telephone number of the service supply side stored in the RAM 8 are collated, and if the telephone numbers match, the transmission signal is automatically sent. Is switched from dial pulse to push tone. That is, if the collation is matched here, it means that the service shop of the telephone number has received the reservation service at least once in the past.

That is, it means that a call is not made to the service store through the telephone line 4 but to receive a reservation service. Then, in order to receive the reservation service on the service supply side, in order to interact with the computer there, it is necessary to use a push tone as the transmission signal. Instead of manually turning on the reverse switch 12, the reverse switch 12 is turned on on the device side. That is, the outgoing signal is automatically switched from dial pulse to push tone.

That is, in the present embodiment, unlike the conventional case, 2
When making reservations after the first time, it is not necessary for the user to switch the transmission signal after the line is connected to the computer of the service shop. As a result, the computer is prevented from transmitting dial pulses, and the user can certainly receive the service.

Next, the operation of printing out the list of service stores stored in the RAM 8 will be described. FIG. 4 is a flowchart showing a control processing routine executed by the CPU 6 of the main controller 2 in this embodiment.

When the processing shifts to this routine, first,
In step 201, it is determined based on the signal from the off-hook detection circuit 19 whether the handset of the attached telephone 5 is in the on-hook state. Here, if the handset is on-hook, the process proceeds to step 202. At step 202, it is judged if the reverse switch 12 has been turned on. Here, when the reverse switch 12 is turned on by the user, the process proceeds to the next step 203. In steps 203 and 204, it is determined whether or not the copy switch 13 has been turned on within 5 seconds after the reverse switch 12 was turned on. If it is determined that the copy switch 13 has been turned on within 5 seconds, the process proceeds to step 205.

In step 205, the recording unit 11 is operated and the telephone number of the service store stored in the RAM 8 is printed out. On the other hand, the step 202
At 5 seconds after the reverse switch 12 is turned on and the copy switch 13 is not turned on,
Subsequent processing is ended. That is, when the copy switch 13 is not turned on within 5 seconds after the reverse switch 12 is turned on, it is determined that the user simply switches the reverse switch 12 to switch the transmission signal. To be done.

As described above, when the reverse switch 12 is switched and the copy switch 13 is turned on within 5 seconds after the handset is hooked on, the recording unit 11 stores it in the RAM 8. The telephone number of the designated service store is printed out.

That is, by printing out the telephone number of the service store, the user does not have to record the telephone number in a notebook or the like each time. As a result, not only does the user not have to open a notebook etc. each time a reservation is made,
It is possible to easily receive the service from a public telephone (in this case, a public telephone using a push line) by looking at the printed sheet.

The present invention is not limited to the above-mentioned embodiments, but may be configured as follows, for example, within the scope of the invention. (1) In the above embodiment, the facsimile device 1 provided with the auxiliary telephone 5 is embodied, but it may be embodied in a telephone that can simply switch the dial pulse and push tone transmission signals.

(2) In the above embodiment, the telephone number of the service supply side stored in the RAM 8 is arranged to be printed out by operating the recording section 11. However, this is simply the telephone number of the service supply side. The configuration may be such that the numbers are stored in the RAM 8.

[0053]

As described in detail above, according to the present invention,
When the line with a specific destination is connected, the push tone can be surely transmitted, which is an excellent effect.
