DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a telephone to which a telephone can be connected.
The present invention relates to a facsimile apparatus and a control method thereof .

[0002]

2. Description of the Related Art Conventionally, in a facsimile apparatus in which a child telephone can be connected to a facsimile apparatus main body, when the facsimile apparatus main body is set to a manual reception mode,
It is possible to instruct the facsimile machine body to start receiving from the slave phone, and when the facsimile machine body starts manual reception, the facsimile communication procedure signal is heard from the handset of the slave phone. Are known. Also, when the facsimile apparatus main body starts manual reception as described above, a relay is switched to the communication modem side of the facsimile apparatus, and it is known that the child telephone is configured to be silent. I have.

[0003]

However, in the above-mentioned conventional example, when the reception start is instructed from the slave telephone to the facsimile apparatus main body, the transmission of the communication procedure signal and the silent state occur, so that the following problem occurs.

First, when a facsimile communication procedure signal is heard from a handset of a child telephone, there is a problem that it is hard to hear. In addition, when the facsimile apparatus body starts manual reception by the child telephone, if the handset of the child telephone becomes silent, it is erroneously assumed that an abnormality has occurred in the telephone line. Since it is not possible to determine whether or not the reception has started, it is necessary to go to the facsimile apparatus main body after instructing the start of the manual reception and there is a problem that the effect of the remote reception is reduced.

[0005] The present invention relates to a telephone connected to a facsimile machine.
The hook state of the telephone
Will also determine when you are instructed to start facsimile communication

FIG. 1 is a block diagram showing one embodiment of the present invention, showing a facsimile apparatus main body.

In FIG. 1, a CPU 1 that controls the entire facsimile apparatus performs an operation process according to a program stored in a ROM 2, and executes a RAM 3 and a nonvolatile R
AM4, recording unit 5, reading unit 6, modem 7, NCU 8, operation unit 10, display unit 12, voice message unit 13, pseudo C
The control of the I unit 14 is performed.

The RAM 3 stores the binary data "1" and "0" read by the reading unit 6, stores the binary data for the recording unit 5 to perform recording, and stores the modem 7 And stores the binarized data to be output to the telephone line 9 through the NCU 8. Also, RAM3
Indicates that the analog waveform input from the telephone line 9 is
Store the binarized data demodulated in step (1).

A non-volatile RAM 4 is a RAM for storing data to be stored even when the system power is turned off.
It is. The recording unit 5 includes a DMA control control IC,
It is constituted by a thermal head or the like, and prints out according to the recording data stored in the RAM 3.

The reading unit 6 includes a DMA controller, CC
D, which is composed of a control IC and the like, binarizes the data read by the CCD, sequentially encodes the values, and sends them to the RAM 3. The modem 7 includes a clock generation circuit, modulates transmission data stored in the RAM 3, and demodulates an analog signal input from the telephone line 9. At the time of the receiving operation, the modem 7 identifies the DTMF sent from the other party, evolves the data into 16 bits,
It is sent to M3. The NCU 8 switches and connects the telephone line 9 to either the modem 7 or the connected telephone 10 under the control of the CPU 1.

The operation unit 11 includes a display unit 101, a stop key 103 for stopping a processing operation, a start key 104 for starting an operation, a ten-key 105 for outputting a destination telephone number to the telephone line 9, a facsimile. A manual / automatic slide switch 106 for switching the receiving mode of the
Slider 1 for detecting the width of a document placed on a document conveying table
07. The display unit 12 indicates what state the apparatus is in, and is composed of an LCD or the like. Since the child telephone in the above embodiment is a general one, the child telephone is not shown.

Next, the receiving operation in the above embodiment and the operation when remote reception is performed will be described.

First, during the facsimile standby state, the NCU
When a calling signal enters the NCU 8 via the telephone line 9 connected to the modem 8 and the modem 7 determines that it is a calling signal, the facsimile apparatus body and the connected telephone 9 ring.

FIG. 3 shows the connection telephone 9 in the above embodiment.
It is a flowchart which shows the operation | movement after sounding.

Automatic / manual changeover switch 10 of operation unit 11
6 is set in the automatic receiving side or the manual receiving side in accordance with the program in the ROM 2
U1 judges (S1). When the changeover switch 106 is set to the automatic mode, the main body of the facsimile apparatus is set to the reception state and the facsimile reception operation is started. When the changeover switch 106 is set to the manual mode (S2), the state of the hook switch of the slave phone is detected. If the hook is on-hook, the slave phone goes off-hook with the slave phone ringing. Wait until (S2).

When the child telephone goes off-hook, if the operator determines that the telephone is a telephone (S3), a telephone call is made (S2).
1) When the call ends and the child telephone goes on-hook, the process returns to the standby state for facsimile reception.

On the other hand, when the operator determines that the reception is facsimile (S3), the operator performs a remote reception operation. That is, the operator instructs the facsimile apparatus body to start manual reception from the slave telephone (S4). In response, the main body of the facsimile apparatus starts manual reception.

At this time, the state of the hook switch of the slave telephone is detected (S5). If the hook switch is on-hook, the pseudo CI unit 14 sends the pseudo CI to the slave telephone (S11).
If the operator puts the child phone in the off-hook state (S
5) A message "Remote jusin @ uketsukamita" fixedly registered in advance from the voice message unit 13 is output to the handset of the child telephone (S6), and the process returns to the standby state for facsimile reception.

After off-hook of the sub telephone (S2), the fact that the sub telephone is off-hook in S5 is determined by off-hook of the sub telephone (S2) and performing an off-hook operation after the operator performs off-hook. This is because it is determined that there is no need to perform the operation and the user may go on-hook. In this embodiment, even when the remote receiving operation is completed and the user goes on-hook, the voice message can be heard from the slave phone.

In the above embodiment, the communication procedure signal does not flow from the receiver of the child telephone after the reception start is instructed from the child telephone to the main body of the facsimile apparatus. In addition, since the handset of the child phone does not go into a silent state, it is not mistaken that an error has occurred in the telephone line, and since a voice message flows to the handset of the child phone, manual reception has started. Can be confirmed without going to the facsimile machine body.

FIG. 4 is a flowchart showing the contents of the remote reception operation in the above embodiment.

The remote reception codes "2" and "5" programmed in the ROM 2 are input to the modem 7 by a tone signal, and the modem 7 determines "2" and "5" of the tone signal. Only in the case (S31, S32), remote reception is accepted. That is, the facsimile apparatus body is instructed to start reception. Alternatively, a command may be issued to the facsimile apparatus body to start reception by pressing a start switch or the like provided on the sub telephone.

[0024]

According to the present invention, a connection to a facsimile machine is provided.
The state of the hook of the connected telephone is not limited to the incoming call.
When the phone instructs to start facsimile communication,
Off-hook state when receiving a call.
Facsimile communication from the telephone.
Is determined to be off-hook when instructed to start
In this case, a process suitable for the situation can be performed.
