Abstract

PURPOSE:To suppress the increase in communication charges without deterioration of the quality in data transmission by releasing a line once at a calling side and executing the automatic calling to a transfer destination when a prescribed called side rejects a receiving and informing a transfer destination of the telephone number of the transfer destination. CONSTITUTION:A user sets the telephone number of a communication equipment C of a transfer destination to a communication equipment B at a called side and goes out to an office where a transfer destination exists. When an automatic transmission is applied from the automatic calling device of a communication equipment A of a customer to a communication equipment B at a called side, a CPU 2 in the device sends a communication control procedure 'transfer to a transfer destination C' to a calling side together with the telephone number of the transfer destination and rejects that a message is received. The CPU 2 of the communication equipment A at the calling side releases once the line with the called side, executes the automatic calling to the communication equipment C of the transfer destination again and executes the automatic transmission.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device having an automatic calling function, an automatic re-calling machine, and a communication control procedure.

[Conventional technology] There are two types of conventional transfer devices:

The first method is a method in which when an incoming call is received, the device on the automatic receiving side makes a call to the forwarding destination, and the calling side and the forwarding destination are connected by hardware.

However, this method has the problem that the line quality deteriorates because it is necessary to connect a line, and the information transmission quality deteriorates.

The second method is to temporarily hold automatically received audio and images in a memory, and the receiving device automatically calls the transfer destination and automatically transmits the held contents.

In this method, information is first relayed and received, and then sent.
There is a problem that transmission quality deteriorates, and there is also a problem that a large amount of memory capacity is required, which increases the cost of the entire device.

Furthermore, both of the above methods have the problem that one communication fee is twice as high.

[Object of the Invention] The present invention has been made by focusing on the problems of the conventional example described above, and an object of the present invention is to provide a communication device in which transmission quality does not deteriorate and communication charges do not increase.

[Embodiments of the invention] FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, a crystal oscillator 1 generates a reference clock for the entire device, and this clock is given as a reference clock to a CPU (central processing unit) 2 comprised of a desired microprocessor or the like. The CPU 2 has a ROM 3, a RAM 4, a timer 5, and a PPI (blobable parallel l10) 6 via a data bus and an address bus.
．． 7.10, UPI C peripheral CPU) connected to 9.11.12. The CPU 2 controls the entire facsimile machine and also encodes and decodes image data.

Further, in the control procedure, the CPU 2 in the called side rejects the reception and informs the calling side of the forwarding destination telephone number, as an example of means for the calling side that has automatically made a call to the called side. It is. In the above case, the CPU 2 on the calling side is an example of means for releasing the line and automatically calling the transfer destination telephone number.

The DMA controller 3 controls memories such as the ROM 3 and RAM 4, and the UPI 9 controls the drive of originals and recording paper. Also, UPI 11
The UPI 12 controls the parallel-to-serial converter 25 and the recording system of the thermal head, and the UPI 12 displays the key manual switch 31 and the liquid crystal display 1LcD32.

The modem 14 modulates and demodulates image data and transmits and receives procedure signals for facsimile communication procedures, and the network control unit (NCU) 15 switches the line to the telephone 34 side or the modem 14 side. .

The dialer 16 sends a dial signal to one line in response to the telephone number data of the communication device outputted from the CPU 2 via the PP17.

In addition, a relay 8, a speaker drive circuit 18, a speaker 19, and an analog-to-digital converter 21 are provided.

It is also assumed that the modem 14 is capable of detecting the DTMF of a telephone.

Next, the operation of the above embodiment will be explained.

FIG. 2 is an explanatory diagram showing the operation in the above embodiment.

In this FIG. 2, first, the user
Suppose that you set the telephone number of the forwarding destination communication company C (FIG. 2 (1)) and go to the office where the forwarding destination C is located.

Then, when an automatic transmission is sent from the automatic calling party A, which is a communication device of a business partner, to the called party B, the called party B sends a communication control procedure to the automatic calling party that says "transfer to destination C." A and rejects the message from being received by called party B (
(2) in the same figure), and then both the calling side A and the called side B automatically release the line (CML-off) ((3) in the same figure).

Then, the automatic calling party A automatically calls the transfer destination communication device C and automatically transmits the call ((4) in the same figure). In this case, the transfer destination C
may be a device that does not include the transfer unit.

FIG. 3 is an explanatory diagram of another embodiment of the present invention.

This embodiment is an explanation of an embodiment in which the transfer destination can be changed every hour.

First, the communication aB on the called side is set so that the transfer destination in the morning is 01 and the transfer destination in the afternoon is 02 (FIG. 3 (1)).

Then, the automatic calling party A makes a call to the called party B, and the called party B refuses to receive the message and provides the calling party A with the forwarding phone number according to the time at that time. After that, both the calling side A and the called side B automatically release the line (CML-off) ((3) in the same figure).

Then, if it is in the morning, automatic calling side A calls forwarding destination CI ((4) in the same figure), and in the afternoon, automatic calling side A calls forwarding destination C2 ((4) in the same figure). 5) ).

FIG. 4 is an explanatory diagram of another embodiment of the present invention.

In this embodiment, instead of setting the forwarding destination directly to the called party B, another communication device C instructs the called party, the communication device B, about the destination via a communication line. . In this case, a communication device other than the communication MC, such as a communication device, may set the forwarding destination to the communication device C for the called party B via a communication line.

FIG. 5 is a flowchart showing the above embodiment.

First, upon receiving a paging signal (this is the action of called party B) (SL), it is determined whether a transfer command is set (S2). If the transfer command is not set, that is, ckg is not set as the transfer destination, automatic reception is performed (S3), and if transfer destination C etc. is set, the predetermined transfer control means is not executed. S4).

Turn off. The details of this transfer control means are shown in FIG.

Note that whether or not the transfer command is set in S2 is determined by the CPU 2 inputting the mode setting flag held in the E2ROM 17.

On the other hand, if there is no call signal and the start key is not pressed (35), it is determined whether or not to make an automatic call (S6).
, if the call is being made automatically (in this case,
(This is the operation of the automatic calling party A in the figure), automatic calling processing is performed (S7), and the automatic calling process is turned off (S t O). If an automatic call is not made in S6 and the function key is pressed (S8), the function operation is executed (S9).

On the other hand, if there is no ringing signal and the start key is pressed, it is determined whether or not the user is off-hook (S11).
), if you are off-hook and a document is set (
S12), performs a copying operation (S14), and if no original is set, performs cutting (S14).
5).

If it is on footer in Sll and the original is in the cassette (S13), a transmission operation is performed (316).
, performs reception operation if no original is set (S
17).

Next, a description will be given of the operation when a transfer command is set on the called side B and the transfer is controlled.

FIG. 6 is a flowchart showing detailed operations of the transfer control procedure (S4) shown in FIG.

In this figure, a forwarding destination telephone number is included in N5F (non-standard function identification signal) and NSF is synthesized (S20).
In this case, the NSF is synthesized and held in the RAM4. and NSF, C3I (called terminal identification signal), DIS (
521), NSS (non-standard function setting signal), TSI (transmitting terminal identification signal), C
5I is received (S22).

Here, in the above-mentioned embodiment, control is performed by putting the setting/resetting of the transfer mode and the telephone number of the transfer destination on the NSF and NSS.

Then, transfer control is determined (S23). That is, it is determined whether or not a forwarding destination telephone number has been set using DTMF from the telephone (the embodiment shown in FIG. 4). Specifically, if the transfer destination phone number is not set using the 0 communication line analyzed by the CPU 2 using the NCU 15 and the modem 14, based on the NSS, whether or not the other party has a transfer mode (same mode) is determined. If they have the same mode, they are turned off without receiving them (S27), that is, they send out a DCN (disconnection command signal). On the other hand, if they have the same mode, known automatic reception is performed (S25) and the process returns (S26).

If the forwarding destination phone number is set via one communication line in S23 above, forwarding control processing is performed (S28)
.

FIG. 7 is a flowchart showing the detailed operation of NSF synthesis (S20) in FIG. 6.

In this figure, first, enter the current time (530),
Initialize flag i 331), E2 ROM
17, some pieces of transfer destination information are stored in pairs with transfer times. Referring to this memory, if the transfer destination i does not match the current time (S32), the above i is incremented by 1 (533), and when all the transfer destinations are compared (534), the error flag is set to "1". "Nishiku 535
), return (S36).

In the above case, if the forwarding destination i and the current time match (S
32), put the forwarding destination i on the NSF (337), that is, so that a call can be made to the forwarding destination according to the current time,
Set up NSF.

FIG. 8 is a flowchart showing details of the automatic call processing (S7) in FIG. 5.

The flowchart shown in FIG. 8 is shown in FIGS.
This figure shows the operation of the automatic calling party A shown in the figure.

First, turn on CML (340) and make an automatic call (340).
541), based on the NSF sent from called party B,
Determine whether there is a transfer command input from the other party (S42
). Then, if no transfer command has been input, an automatic call is made (S47) and the process returns (548).
.

On the other hand, callee B sends a transfer command (transfer destination phone number)
If you have entered -H, turn off the CML 543), make the switch standby for the necessary time 344), turn the CML back on 545), and make an automatic call to the specified forwarding destination 546.
), automatic transmission is performed (S47).

FIG. 9 is a diagram showing a transfer address map in the E22 ROM 17 shown in FIG. 1.

In this figure, when the MSB is rlJ, it indicates that a transfer address (transfer destination telephone number) exists, and three lines constitute information for one transfer destination. Among the three lines, the first line is the telephone number of the transfer destination, and the second and third lines indicate the time range in which the transfer should be made to the transfer destination. In other words, it indicates that, for example, from 08:00 to 11:59, the call should be transferred to the telephone number o o o-xxxx. The above telephone number is the telephone number of the transfer destination CI.

By doing the above, the communication time is about half that of the conventional device, and the automatic calling party A can transfer to the transfer destination C, CI, C
Since the data is directly transmitted to 2, the transmission quality is higher than in the past, and the transferability is high.

[Advantageous Effects] According to the present invention, the quality of data transmission from the sender to the transfer destination does not deteriorate and the communication charges do not increase.
