A facsimile 12R, which operates as a receiver, is connected to 0R via cable 2.

The operation of the speed dialing device 10.10R in the configuration described below will be explained with reference to the flowchart shown in FIG.

In the 61'A, the speed dialing device 7110 that operates as a calling side is processed from step 53 to step 65, and the speed dialing device 7110 that operates as a caller from step 71 to step 79 until step 65. This is a flow for processing 10R.

First, speed dial device 10. When the source switch 25 of the IOR is turned on, the microprocessor 1 of the person
4 reads the program from ROM 15 and goes to step 5
Processing starts from 1. Next, in step 52, it is determined whether or not the position key 44 has been pressed, or if it is assumed that it has not been pressed yet, the process proceeds to step 71. Here,
It is detected whether or not a direct call is made from the facsimile 12.12R via the NCU 32 (a call is made using the Atial transmitter provided in the facsimile 12.12R). If you receive this direct transmission, send the Atial signal from Facsimile 12 or Facsimile 12R to the cable! The loop is detected by the NCU 32 via the L1 or the cable connector 2, the connector 36, and the wiring W, and the loop detection information is transmitted to the microprocessor 14 via the lotus 20. Then, the process proceeds to step 63. However, assuming that the facsimile 12.12R does not perform a direct outgoing call operation, the loop is not detected in step 71, so the process proceeds to step 72, and the NCU 32 performs incoming call detection.
Since the incoming call is not detected yet, ILF and SDP 52
Returning to the previous step, it is detected whether or not the previous device key 44 is in the ON state. Therefore, the shortening tire device 10.
1OR continues in steps 52 → 71 → until the position key 44 is pressed or an incoming call is detected in step 72.
It is waiting in a loop of 72→52.

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

First, after setting the document in the facsimile 12, press the ENTER key 44 of the speed dialing device IO on the calling side. (However, if the speed dial device 1 installed at the desired subscriber, i.e., the called party
Assume that 0R is still waiting in the loop of steps 52→71→72→52. ) Step 53 waits for the desired subscriber's abbreviated number (indicated in the figure as rID NoJ) to be input from the numeric keypad 47, and once input, the abbreviated number is sent to the microprocessor 1.
Save in register within 4. Also, at step 54,
The abbreviated number stored in the register is displayed on the liquid crystal display 17. Then, in step 55, if the [1] key 44 is pressed twice indicating the end of the input operation of m1xs>,
In step 56, a search is made to see if there is a number in the RAM 22 that matches the manually entered abbreviated number. If the entered abbreviated number − and −・ are detected,
The phone number of - stored corresponding to that abbreviated number (
Shown in NoJ and IA. ) is read from the RAM 22. Then, in step 57, this telephone number -
) is output to the PB oscillator 30. The PB oscillator 30 converts the telephone number - into a predetermined dial signal, and also connects the wiring W,
, NCU32, wiring W4゜relay contact 33 terminals A, C
It is sent to the exchange 11 via the route of the first distribution Mws, the connector 35, and the communication line, and waits for the detection of an incoming call in step 58.

If the exchange 11 receives the dial signal and selects the communication line L2, it returns the incoming signal to the shortening dial device IO, and the process proceeds to step 59.

Incidentally, in step 56, if the entered abbreviated number and circular item cannot be retrieved in the RAM 22, the process proceeds to step 66, where a predetermined error is displayed on the liquid crystal display 17, and the process proceeds to step 52, where the process waits. Return to state. Further, in step 58, if the speed dial device 10R on the called side is already exchanging information with another speed dial device 10, the exchange 11 does not send the incoming signal to the speed dial device 10, even if it waits for a predetermined period of time. Step 6
Proceed to step 7, count by one in the counter circuit 16, and count a predetermined number of times (so-called automatic + tf dial number, for example, 3 times).
If the number has not been reached, the process proceeds to step 57, and a dialing message is automatically sent out again in the same manner as described above. Note that the number of automatic +t+dials 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 outputs it to the PB oscillator 30. Then, the PB oscillator 30 converts this abbreviated number into a predetermined signal, and transmits it to the abbreviated dialing device 10R on the called side via the same route as the one used to send the telephone number, to the exchange 11, and further via the communication line L2. Then, in step 6o, it waits for the abbreviated number to be returned from the abbreviated dial device 10R on the receiving side. Specifically, a reception command from the PB signal receiver 31 or the microprocessor 14 is input, and the communication line L2. Exchange 11, communication line 7, connector 35
, wiring W5, end of relay contact 33/-C, A, wiring W,

On the other hand, when the speed dial device 10R on the called side selects the exchange 11 as the communication line L2, it sends a dial signal to the speed dial device 10R on the called side or the switch 11 in the same way as described in step 58. Send, step 72
The incoming signal is detected at step 73, and the process proceeds to step 73. The microprocessor 14 then reads out its own abbreviated number stored in a predetermined location in the RAM 22 and outputs it to the PB oscillator 30 in step 73. Then, the PB oscillator 30 converts the abbreviated number to a predetermined number, and distributes &

a 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

If the abbreviated number t;- is detected, the process proceeds to step 75, where it is determined whether or not the own abbreviated number held in the RAM 22 matches the received abbreviated number t;-, and if the match is confirmed, Step 7
6, a predetermined display is performed, and in step 77, the NCU
The RG sending command is sent to JP32. Then, the NCU 32 connects the RG to the wiring W, , W, the connector 36, the cable car,
The facsimile 12R rings the 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, microprocessor 14 performs step 78.
Then, a relay drive command is output to the relay drive circuit 34 via the lotus 20. Then, the relay drive circuit 34
A current is passed through 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
Since it is switched to the facsimile 12R side via the connector 35 and the wiring W5, the facsimile 12R is ready to receive data! It becomes. Then, at Ste Mbu 79, N
The system waits for an incoming call to be detected via the CU 32.

In step 73, when the abbreviated number transmitted from the abbreviated dialing device 10R on the called side reaches the abbreviated dialing device 10 on the calling side via the communication line L2, the exchange 11, and the communication line, this abbreviated number -) is distributed. mW5. ! J Shijja
Point 33 E f C, A, wiring W4. The signal is received by the PB receiver 31 via the NCU 32 and the wiring W6, and demodulated into a predetermined digital signal t). Then, the microprocessor 14 in the shortening terminal device 10 on the receiving side
In step 60, the abbreviated number is stored in another register, and in step 59 it is checked whether it matches the abbreviated number transmitted. If it is confirmed in step 61 that they match, the process advances to step 62 and the RG is sent to NCtJ32.
Reset the command to send out. NCU32 is RG
is output to the facsimile 12 via the wiring W□, Wl, the connector 36, and the cable car, and a bell is rung 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, d communication line L1
The end of connector 35 and wiring W5. It is switched to facsimile 120m via relay contact 33. Then, the facsimile 12 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. Once the facsimile 12 has finished transmitting/receiving operations, the loop of steps 64→63→64 is exited and the process proceeds to step 65 since no incoming call detection is performed. This step 6
5, the microprocessor 14 releases the communication line 5, 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 is the connector 35. It is switched to the shortening tire system 10 side via the wiring W, . Then, the process returns to step 52, and then step 52→71-.

Waits in a loop of 72→52.

Step 61 If the microprocessor 14 does not confirm that the reduced number is -, the microprocessor 14 proceeds to step 68 and waits for a predetermined time while determining whether or not the confirmation key 42 has been pressed. If the confirmation key 42 is pressed, the process advances to step 62 and the RG is output to the facsimile 12 via the NCU 32. Then, steps 63, 64, and 65 are performed in the same manner as described above. Possible reasons why the abbreviated numbers do not match are: - If the abbreviated number is not returned at all from the abbreviated dialing device 10R on the called side, - If the abbreviated number is returned but cannot be received correctly due to noise or other factors.

■It is possible that there was a registration error when registering the abbreviated number and telephone number in the RAM 22. In such a case, if a predetermined confirmation process is performed and it is determined that it is OK to transmit to the subscriber side of the currently selected communication line L2, the communication is forced by pressing the confirmation key 42. We are also considering the possibility of doing so. Incidentally, if the confirmation key 42 is in the OFF state in step 68, step 6
Step 6 displays a predetermined error, and step 52
Return to

Speed dialing device on the receiving side'i! In lf OR,
While the sending/receiving operation is being performed between the facsimile machines 12 and 12R, the NCU 32 detects a flea (0 -), so the process loops from steps 79 to 78 to 79, and the sending and receiving operations between the facsimile machines 12 and 12R are terminated. Wait until. Then, once this transmission/reception operation is completed, the NCU 32 will no longer detect incoming calls, so the microprocessor 14 proceeds to step 65 and relay drive circuit 3
A reset command is output to 4. Then, the relay drive circuit 34 returns the relay contact 33 to the normal state, so the end of the 1 communication line L2 is connected to the connector 35, and the wiring &! It is switched to the speed dial device 10R side via AWS and released. Thereafter, the process returns to step 52, and step 52.
71 → 72 → 52 loop and wait. Said step 7
If it is found in step 5 that there is a mismatch between the abbreviated number () received by the abbreviated dialing device 10R on the called side and the own abbreviated number attached to the called side -I, 1, then step 80
Then, it is determined whether the confirmation key 42 has been pressed in the same way as explained on the calling side. Confirmation key 42 is ON! If it is, the process advances to step 77 and the R
G is output to the facsimile 12R, and a bell is rung for a predetermined period of time. Then, the process proceeds to step 78, in which the facsimile machines 12 and 12R start transmitting and receiving operations in the same manner as described above. In step 75, the reasons why the abbreviated numbers do not match are: - The abbreviated number is not sent at all from the calling party, - The abbreviated number is sent but not received correctly due to noise, etc., - The abbreviated number in the RAM 22 There may be a mistake in registering the phone number. In such a case, the receiving side also performs a predetermined confirmation process, and if the calling side determines that it is OK to receive the call, press the +if confirmation key 42 to forcibly send the facsimile 12.
．． It is considered that transmission and reception operations can be performed between 12Rs. Incidentally, when it is determined in step 80 that the confirmation key 42 is in the OFF state, the process proceeds to step 81, a predetermined error display is performed, and the process proceeds to step 65.
, the communication line L2 is released and information from the calling side is not accepted, and the process returns to step 52.
→ 71 → 72 → 52 loop and wait.
