This invention relates to a speed dial device for dialing.

[Conventional technology]

Conventional speed dialing devices, such as push-button telephones, have a specific subscriber's phone number and its corresponding speed phone number (hereinafter referred to as
It's called an "abbreviated number." ), and when a desired subscriber's abbreviated number is input from among the memorized abbreviated numbers, the corresponding telephone number is read out, and this telephone number is converted into a predetermined dialing signal and sent. It calls the communication partner. In a network consisting of subscribers registered as abbreviated numbers (for example, between a head office and a branch office), a unique abbreviated number is assigned to the telephone number of each abbreviated dial device, and within a subscriber group in the network, It has become common to use abbreviated numbers uniformly because it is convenient.

[Problem that the invention seeks to solve]

However, such conventional abbreviated dialing devices cannot prevent push button operation errors or registration of incorrect abbreviated numbers, and the reliability of registration is lacking. Furthermore, when abbreviated numbers are used uniformly within a specific subscriber group, it becomes necessary to register all devices at the same time regarding these abbreviated numbers.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an abbreviated dialing device that can perform registration work regarding abbreviated numbers all at once and reliably.

In order to achieve this object, the present invention, as shown in FIG. a first confirmation means 3 for checking whether a telephone number corresponding to the abbreviated number accepted by the input means 2 exists in the storage means 1; a holding means 7 for holding an identification code assigned to a person; and a holding means 7 for converting the telephone number corresponding to the abbreviated number received by the input means 2 into a dial signal and sending it to the exchange via a communication line, and holding it in the holding means 7; a transmitting means 4 for transmitting a predetermined identification code to the called party; a second checking means 8 for checking whether the received identification code matches the identification code held by the holding means 7; Sometimes, the reply means 9 sends back the identification code via the transmission means 4, and when the transmitted identification code is received and the returned identification code is received, the reply means 9 sends back the identification code via the sending means 4. and a switching means 5 for switching the communication line from the speed dial device side to the communication device 6 side after the second confirmation means 8 confirms the coincidence, and the storage means 1 and the holding means 7 are built in the storage card. This memory card is removable.

The operation of the speed dialing device according to the present invention will be explained.

First, memory cards with registered abbreviated numbers and the like are prepared in advance and distributed to locations where each abbreviated dialing device is installed. Then, this memory card is attached to the speed dialing device.

Then, in the abbreviated dialing device on the calling side, the input means 2 receives the abbreviated number corresponding to the telephone number.

The first confirmation means 3 confirms whether the telephone number corresponding to the abbreviated number received from the input means 2 exists in the storage means 1.

When the first confirmation means 3 confirms that the telephone number corresponding to the abbreviated number exists in the storage means 1, the transmission means 4 converts the telephone number into a dial signal and sends it to the converter via the communication line. .

Then, the exchange selects the communication line corresponding to the received telephone number. Therefore, the called speed dialing device is selected.

Further, the communication means 4 sends the identification code from the holding means 7 to the speed dialing device of the receiving side via the communication line and the converter.

In the speed dialing device on the called side, when an identification code arrives from the speed dialing device on the calling side, the second confirmation means 8 checks whether the identification code matches the identification code held in the holding means 7. .

When it is confirmed that the identification codes match, the reply means 9
transmits the identification code held by the holding means 7 to the transmitting means 4
to be sent via .

Thereafter, the switching means 5 switches the end of the communication circuit from the speed dial device side to the communication device 6 side.

In the speed dialing device on the calling side, when an identification code arrives from the called side, the second confirmation means 8 checks whether the identification code and the identification code held in the holding means 7 match.

When the second confirmation means 8 confirms that the identification codes match, the switching means 5 switches the end of the communication line from the speed dial device to the communication device 6.

Therefore, both communication devices 6 start transmitting and receiving information via the communication line and the exchange.

The configuration of this speed dial device 10R is the same as that shown in FIG. 3, and the external plan view is also the same as that shown in FIG. 5, so a description thereof will be omitted. In addition, the speed dial device 1 on the receiving side
A facsimile 12R, which operates as a receiver, is connected to 0R via a cable _l2 .

Speed dial device 10, 1 in the above configuration
The operation of 0R will be explained based on the flowchart shown in FIG.

In FIG. 6, steps 53 to 65 show the speed dialing device 10 operating as a calling party.
Steps 71 to 79 and up to step 65 are the steps processed by the abbreviated dialing device 10R, which operates as the called party.

First, when the power switches 25 of the speed dial devices 10 and 10R are turned on, each microprocessor 14 reads a program from the ROM 15 and starts processing from step 51. next,
At step 52, it is determined whether or not the TEL key 44 has been pressed. If it is assumed that the TEL key 44 has not been pressed yet, the process proceeds to step 71. Here, NCU32
It is detected whether a direct call (call operation using the dial call function provided in the facsimile 12, 12R) is made from the facsimile 12, 12R via the facsimile 12, 12R. When this direct transmission occurs, the NCU 32 detects the dial signal from the facsimile 12 or the facsimile 12R as a loop via the cable l ₁ or cable l ₂ , the connector 36 and the wiring W ₁ , and sends it to the microprocessor 14 via the bus 20. transmits loop detection information to. Then proceed to step 63. However, facsimile 12, 12R
Assuming that there is no direct call operation from the NCU 32, the loop is not detected in step 71, so the process proceeds to step 72, where the NCU 32 detects an incoming call.
Since the incoming call has not yet been detected, the process returns to step 52 and detects whether the TEL key 44 is turned on, as described above. Therefore, the speed dial devices 10, 10R wait in a loop of steps 52→71→72→52 until the TEL key 44 is pressed or until an incoming call is detected at step 72.

Therefore, the following description assumes that the facsimile 12 transmits information to a desired subscriber while on standby in such a state.

First, after setting a document on the facsimile 12, when the TEL key 44 of the speed dial device 10 on the calling side is pressed, the process exits from step 52 of the loop of steps 52→71→72→52 and proceeds to step 53.
(However, it is assumed that the speed dialing device 10R on the called side is installed at the desired subscriber. In other words, it is assumed that the short dialing device 10R on the called side is still waiting in the loop of steps 52 → 71 → 72 → 52.) In step 53, the desired subscriber The system waits for the abbreviated number (indicated as "ID No." in the figure) of the person to be entered from the numeric keypad 47, and when the abbreviated number is input, the abbreviated number is stored in a register within the microprocessor 14. Further, in step 54, the abbreviated number stored in the register is displayed on the liquid crystal display 17. Then, in step 55, when the TEL key 44 is pressed for the second time indicating the end of the abbreviated number input operation, it is checked in step 56 whether or not there is an abbreviated number that matches the entered abbreviated number in the RAM 22. search for. If a number matching the entered abbreviated number is detected, the first telephone number ("TEL No.") stored corresponding to that abbreviated number will be displayed.
is shown in the figure. ) is read from the RAM 22. Then, in step 57, enter this phone number into PB.
Output to oscillator 30. The PB oscillator 30 converts the telephone number into a predetermined dialing signal and also performs wiring.
W ₇ , NCU 32, wiring W ₄ , terminals A and C of relay contact 33, wiring W ₅ , connector 35, communication line L ₁
It is sent to the exchange 11 via the route , and waits for detection of incoming call in step 58. If the exchange 11 receives the dial signal and selects the communication line _L2 ,
Since the incoming call signal is returned to the speed dialing device 10, the process proceeds to step 59. In addition, if it is not possible to search the RAM 22 for the same abbreviated number as the entered abbreviation number in step 56, proceed to step 66.
A predetermined error message is displayed on the liquid crystal display 17, and the process proceeds to step 52 to return to the standby state. Further, in step 58, if the speed dialing device 10R on the receiving side is already exchanging information with another speed dialing device 10, etc., the exchange 11 does not send the incoming signal to the speed dialing device 10, even if it waits for a predetermined period of time. Since the counter circuit 16 does not reply, the process goes to step 67 and the counter circuit 16
If the predetermined count number (the so-called automatic re-dial number, for example, 3 times) has not been reached, the process proceeds to step 57, and a dialing signal is automatically sent out again in the same manner as described above. Note that the number of automatic redials can be set in advance, as will be described later. When the count value in the counter circuit 16 reaches a predetermined number of times, a predetermined error display is displayed on the liquid crystal display 17, and the process returns to step 52 to enter a standby state.

In step 59, the microprocessor 14 retrieves the abbreviated number already stored in the register and stores it in the PB.
Output to oscillator 30. Then, PB oscillator 30
converts this abbreviated number into a predetermined signal and sends it to the exchange 11 via the same route as when sending the telephone number, and then to the abbreviated dialing device ₁₀ on the receiving side via communication line L2.
Send to R. Then, in step 60, it waits for the abbreviated number to be returned from the abbreviated dialing device 10R on the called side. Specifically, the PB signal receiver 31
inputs the reception command from the microprocessor 14 and connects the communication line L ₁ , the exchange 11, the communication line L ₁ ,
Wait for the abbreviated number that arrives along the route of connector 35, wiring W ₅ , terminals C and A of relay contact 33, wiring W ₄ , NCU 32, and further wiring W ₆ .

On the other hand, in the speed dial device 10R on the called side,
When the exchange 11 selects the communication line _L2 , the exchange 11 also sends an incoming signal to the short dialing device 10R on the called side, as explained in step 58, so this incoming signal is detected in step 72. Then proceed to step 73. Then, the microprocessor 14 reads out its own abbreviated number stored in a predetermined location in the RAM 22, and in step 73
Output to PB oscillator 30. Then, PB oscillator 3
0 converts the abbreviated number into a predetermined signal and wires it.
W ₇ , NCU 32, wiring W ₄ , terminals A and C of relay contact 33, wiring W ₅ , connector 35, communication line L ₂ ,
A reply is sent to the speed dial device 10 on the calling side via the exchange 11 and the communication line _L1 . Next, the microprocessor 14 receives the abbreviated number output from the calling party in step 74. Specifically, the PB signal receiver 31 connects the communication line _L1 , the exchange 11, the communication line _L2 , the connector 35, the wiring _W5 , and the relay contact 3.
This is to detect only the abbreviated number from among the signals arriving through the route of terminal C, A wiring W ₄ , NCU 32, and wiring W ₆ of No. 3. If the abbreviated number is detected, the process proceeds to step 75, where it is determined whether the own abbreviated number held in the RAM 22 matches the received abbreviated number, and if the match is confirmed,
Proceed to step 76, perform the specified display, and then proceed to step 76.
At step 77, an RG sending command is given to the NCU 32. Then, the NCU 32 sends the RG to the facsimile 12R through the route of the wires W ₃ and W ₁ , the connector 36, and the cable l ₂ , so the facsimile 12R rings a bell for a predetermined period of time. At this time, if the facsimile 12R is set to automatic reception mode, the receiving subscriber does not need to perform any operation. After a predetermined period of time, the microprocessor 14 proceeds to step 78 and outputs a relay drive command to the relay drive circuit 34 via the bus 20. Then, relay drive circuit 3
4 applies current to the built-in coil to drive the relay contact 33 to the state shown by the dotted line. Therefore, the end of the communication line _L2 is switched to the facsimile 12R side via the connector 35 and the wiring _W5 , so that the facsimile 12R becomes ready for reception. Then, in step 79, the process waits for incoming call detection via the NCU 32.

In step 73, the speed dial device 10 of the called party
When the abbreviated number sent from R reaches the calling side's abbreviated dialing device 10 via communication line _L2 , exchange 11, and communication line _L1 , this abbreviated number is
W ₅ , terminals C and A of relay contact 33, wiring W ₄ ,
NCU32, PB signal receiver 31 via wiring _W6
The received signal is received at the terminal and demodulated into a predetermined digital signal. Then, in step 60, the microprocessor 14 in the speed dialing device 10 on the calling side performs the following steps.
Save said abbreviated number in another register and step
Check whether it matches the abbreviated number sent in step 59. When a match is confirmed in step 61, the process proceeds to step 62, where a command is given to the NCU 32 to send out RG. The NCU 32 outputs RG to the facsimile 12 via the wires W ₃ and W ₁ , the connector 36, and the cable l ₁ , and rings a bell for a predetermined period of time. Next, the microprocessor 14 proceeds to step 63 and drives the relay contact 33 via the relay drive circuit 34 to switch to the state shown by the dotted line. Therefore, the end of the communication line _L1 is connected to the connector 35 and the wiring.
W ₅ , facsimile 12 via relay contact 33
Switched to the side. The facsimile 12 then automatically starts transmitting and receiving operations. Further, the microprocessor 14 proceeds from step 63 to step 64 and detects an incoming call via the NCU 32. When the facsimile 12 completes the transmission/reception operation, the process exits from the loop of steps 64→63→64 and proceeds to step 65 since no incoming call detection is performed. In step 65, the microprocessor 14 releases the communication line _L1 , and specifically outputs a reset command to the relay drive circuit 34. Then, the relay drive circuit 34 cuts off the current to the built-in coil and returns the relay contact 33 to its normal state. Therefore, the end of the communication line _L1 is connected to the speed dial device 10 via the connector 35 and the wiring _W5 .
can be switched to the side. Then, the process returns to step 52, and then waits in a loop of steps 52→71→72→52.

If it is not possible to confirm that the abbreviated numbers match in step 61, the microprocessor 14 proceeds to step 68 and waits for a predetermined time while determining whether or not the confirmation key 42 is pressed. Confirmation key 4
If 2 is pressed, go to step 62 and NCU
32 to output the RG to the facsimile 12. Then, as described above, step 63, 64,
Performs 65 processes. The reason why the abbreviated numbers do not match is that if the abbreviated number is not returned at all from the abbreviated dialing device 10R on the called side, or if the abbreviated number is returned but cannot be received correctly due to noise etc., the abbreviated number in the RAM 22 This may be due to a registration error when registering the phone number. In such a case, if you perform a predetermined confirmation process and find that it is OK to send to the subscriber side of the currently selected communication line _L2 , press the confirmation key 42 to force communication. We are also considering making it possible to Incidentally, if the confirmation key 42 is in the OFF state at step 68, the process advances to step 66, where a predetermined error is displayed, and the process returns to step 52.

In the speed dial device 10R on the called side,
Since the incoming signal is detected by the NCU 32 while the transmission/reception operation is being performed between the facsimile machines 12, 12R, a loop is executed at steps 79→78→79, and the process waits until the transmission/reception operation between the facsimile machines 12, 12R is completed. When this transmission/reception operation is completed, the NCU 32 will no longer detect incoming calls, so the microprocessor 14 proceeds to step 65 and outputs a reset command to the relay drive circuit 34. Then, the relay drive circuit 34 returns the relay contact 33 to the normal state, so the end of the communication line L ₂ is connected to the connector 35 and the wiring W ₅
is switched to the speed dialing device 10R side via , and released. Then return to step 52,
Waits in a loop of steps 52→71→72→52. In step 75, the called speed dial device 1
If a discrepancy is found between the abbreviated number received by the 0R and its own abbreviated number assigned to the called party, the process proceeds to step 80 and checks whether the confirmation key 42 has been pressed in the same way as explained on the calling party. Determine. If the confirmation key 42 is in the ON state, the process proceeds to step 77, where RG is outputted to the facsimile 12R via the NCU 32, and a bell is rung for a predetermined period of time. Then, the process proceeds to step 78, where transmission and reception operations are started between the facsimiles 12 and 12R in the same manner as described above. In step 75, the reason why the abbreviated numbers do not match is that the calling party did not send an abbreviated number at all, that the abbreviated number was sent but could not be received correctly due to noise, etc., or that the abbreviated number and telephone number in the RAM 22 There may be a registration error, etc. In such a case, the receiving side also performs a predetermined confirmation process, and if it is determined that it is OK to receive the call from the calling side, pressing the confirmation key 42 forces the facsimile number 1.
It is considered that transmission and reception operations can be performed between 2 and 12R. In addition, step 80
If it is determined that the confirmation key 42 is in the OFF state, the process proceeds to step 81, where a predetermined error is displayed, and the communication line _L2 is released at step 65.
The process returns to step 52 and waits in a loop of steps 52 -> 71 -> 72 -> 52 with no information being accepted from the calling side.

The speed dial device 10 also has the following service functions: Self-speed dial registration function After pressing a predetermined key, when the user enters the pre-assigned registration number from the numeric keypad 47, the microprocessor 14 registers this number.
Store it at a specified location in RAM22.

Registration Function When the registration key 41 is pressed and the abbreviated number and telephone number are entered using the numeric keypad 47, the microprocessor 14 stores these numbers in correspondence with predetermined locations in the RAM 23, respectively. The end of the operation is instructed by the end key 43.

Date and time setting function After pressing the specified key, when date and time information is entered from the numeric keypad 47, the microprocessor 14 inputs this information to the calendar timer 2.
Set to 8.

Automatic redial count setting function After pressing a predetermined key, when the automatic redial count is input from the numeric keypad 47, the microprocessor 14 stores this value in a predetermined location in the RAM 22.

Printer ON/OFF setting function Press the specified key and then press the specified key on the numeric keypad 47 to turn on the microprocessor 14.
The printer is turned on/on at the specified location in RAM22.
Set the OFF flag.

RAM copy function After installing a RAM 22 similar to the RAM 22 described above in the connector 21a, when a predetermined key is pressed, the microprocessor 14 sequentially reads out information from the RAM 22 installed in the connector 21, and the RAM 22 installed in the connector 21a. RAM22
All information is copied at high speed by sequentially writing to the same location.

In this embodiment, the storage means 1 is
Although the case has been described in which the RAM 22 is implemented using a CMOS element or the like, any storage means 1 that is removable may be used, so that it can also be implemented in, for example, a cassette tape storage device.

Further, in this embodiment, the communication device 6 is used to communicate between the facsimile machines 12 and 12R, but it is needless to say that the communication device 6 is not limited to this and may be a telephone, a computer terminal device, or the like.

As explained above, according to this embodiment, if the entered abbreviated number cannot be searched in the RAM 22, no communication line will be selected, and even if the wrong party is selected due to a registration error, the other party will not be able to contact you. Even if a communication line other than the desired party is selected because the abbreviated number is not returned, subsequent processing can be interrupted and no information will be sent, making it possible to maintain confidentiality. , RAM2 that stores telephone numbers, abbreviated numbers, and identification codes.
Since the RAM 22 is removable, the registration time can be significantly reduced compared to registering by directly operating the push button, and registration can be done simultaneously and reliably by simply distributing the RAM 22 and attaching it to each speed dial device. It is effective if you can do this.

〔Effect of the invention〕

As explained above, according to the present invention, communication is started after both the receiving side and the calling side confirm whether the identification code is a predetermined one using an identification code, and the communication is started by using an identification code. The telephone number, abbreviated number, and identification code of each abbreviated dialing device belonging to the above are stored in a memory card, and this memory card is made removable from the abbreviated dialing device.

Therefore, the confidentiality of communication within a subscriber group is ensured, and the above-mentioned memory card can be distributed to each speed dialing device in the subscriber group and the communication can be carried out simultaneously and reliably by simply installing it in each speed dialing device.
