Description

Description: TECHNICAL FIELD The present invention relates to a facsimile machine having an external telephone, and more particularly to a facsimile machine having a transfer function from an external telephone.

(Prior Art) Facsimile machines are provided with a handset, and many of them are provided as an attached telephone so that telephone communication can be performed. In the case of an incoming call, either telephone call or facsimile reception is selected, and the reception mode for that can be set.

The reception mode includes an automatic reception mode and a manual reception mode, and it is usual to select and set either one.

In the automatic reception mode, when an incoming call is received and the handset is not off-hook within a predetermined number of bell sounds, for example, three times, the facsimile apparatus shifts to the facsimile reception mode and the facsimile procedure is performed. is there.

The manual reception mode is a mode in which the incoming call is limited to a telephone call, the handset is off-hook to make a telephone call, and the facsimile apparatus is switched to the facsimile reception mode by a notification from the sender, and then the facsimile procedure is performed.

In either mode, if the handset is picked up at the time of an incoming call and it is found that the reception is a facsimile reception, the facsimile procedure is performed by switching the facsimile apparatus to the facsimile reception mode.

In many of such facsimile machines, an external telephone can be connected. Since the external telephone is provided separately from the attached handset, it may be installed in a place apart from the facsimile machine, for example, in a room different from the room in which the facsimile machine is installed.
In any case, it is far from the facsimile machine.

When an external telephone goes off-hook for an incoming call,
If the facsimile device is in the automatic reception mode and the incoming call is a facsimile, the facsimile device must be switched to the facsimile mode. Even in the manual reception mode, when the sender prepares to send a facsimile, the facsimile machine must be switched to the facsimile mode at that stage. In addition, even if the incoming call is a telephone call, it may be necessary to transfer the call to a location where the facsimile device is located.

In this way, when transferring an incoming call from the external telephone to the facsimile machine, the external telephone transmits a specific signal and sends it to the facsimile machine, and the facsimile machine switches to the facsimile mode in response to this DTMF signal. In addition, a facsimile machine which is capable of ringing a ringing bell of the facsimile machine is being developed.

For example, after receiving an incoming call, you can select "6
When the "6" is sent, the facsimile machine is switched to the facsimile mode, and when the "00" is sent, the ringing sound of the facsimile machine is ringed to prompt the user to pick up the attached handset.

However, as an attached telephone and an external telephone, there is a facsimile machine which uses a telephone which operates directly by a DC voltage from a line. In such a telephone, since the operation buttons of the facsimile can be used for the attached telephone, the reception mode of the facsimile can be switched or the call can be transferred to an external telephone when an incoming call goes off hook. However, the external telephone has only dial buttons, and when switching from the line, there is a problem that a DC voltage is lost and therefore a signal for transfer or an extension call cannot be performed.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned circumstances, and in a facsimile apparatus having an attached telephone and an external telephone, an incoming call picked up by taking the external telephone off-hook,
It is an object of the present invention to provide a facsimile machine and a facsimile machine capable of transferring to the attached telephone.

(Means for Solving the Problem) The present invention relates to a facsimile apparatus having an attached telephone and an external telephone, a direct current power source, a modulation means for modulating the direct current power source, both telephones on a line side and the direct current power source side. Switching means for selectively connecting to the telephone, storage means for storing the presence / absence of a bell sound when an incoming call is received, storage means for storing a call to an external telephone, and off-hook detection means for detecting the hook state of both telephones. , Has a control means for controlling the switching means in accordance with the contents stored in each of the storage means and the output of the off-hook detection means. The control means always connects both telephones to the line side, and both telephones are connected during an extension call. The telephone is connected to the DC power source side and modulates the DC power source when an extension call is made. When the external telephone is switched from the line side, the DC power source is connected. The transmission signal can be transmitted from the external telephone by connecting the source to the external telephone.

Hereinafter, each operation described above will be described.

Facsimile automatic reception mode In this mode, the automatic reception mode is set in the operation unit 11. The flow starts when an incoming call arrives.
Since it is a facsimile reception, the incoming call bell rings. Step
At 200, the incoming call detection circuit 18 detects an incoming call bell, and the process proceeds to Step 201, and the fact that there is a calling bell is stored in the RAM 9. Since it is set to the automatic reception mode, from Step202 to Step203
If one of the telephones does not go off-hook within the set number of bell tones, for example, two times, go to Step 204 to switch the line to the modem side and go to Step 205 to perform the facsimile reception procedure. And the flow ends.

In Step 203, if any of the telephones goes off-hook within two times of the bell sound, the process proceeds to Step 206. In that case, it is the same as described below.

Facsimile reception mode in which telephone A is off-hook This is the case where telephone A picks up facsimile reception. There are a case where the facsimile apparatus is set to the manual reception mode and a case where the facsimile apparatus is set to the automatic reception mode and the telephone A is off-hook within a predetermined number of bells.

In the former case, the process proceeds from Step 200, 201, 202 to Step 206. In the latter case, the process proceeds from step 203 to step 206. Since the telephone set A is off-hook, the process proceeds to Step 220, the telephone set B is separated from the line, and Steps 221 to 224 are looped. During this time, the telephone A can communicate with the outside line.

If you push down the communication button of the facsimile machine, Step22
From 1 to Step 225, the line is switched to the modem side for transfer, and in Step 226, since no original is set, the process proceeds to Step 228, the facsimile reception procedure is performed, and the flow ends.

Facsimile reception mode off-hook by telephone B This is a case where telephone B picks up facsimile reception. There are a case where the facsimile apparatus is set to the manual reception mode and a case where the facsimile apparatus is set to the automatic reception mode and the telephone B is off-hook within a predetermined number of bells.

In the former case, the process proceeds from Step 200, 202, 202 to Step 206. In the latter case, the process proceeds from Step 203 to Step 206. Since the telephone set A is on-hook, the process proceeds to step 207, and the RAM 9 does not store "calling the telephone set B", the process proceeds to step 209. If telephone B is on-hook, loop to Step 206. If the telephone set B is off-hook, or if it is off-hook, the process proceeds to Step 210 and the telephone set A is disconnected.
Is separated from the line 4 and the “bell sound” stored in RAM 9 in Step 201 causes the process to move from Step 300 to Step 301.

Here, for example, if "66" is dialed from the telephone set B, the process shifts from Step 301 to Step 304, the line is switched to the modem side to perform the transfer, the process proceeds to Step 305, the facsimile reception procedure is performed, and the flow is executed. finish.

Facsimile transmission mode When the original is set on the reading unit 14 and the telephone A is hooked off, the flow starts. Since there is no incoming call bell, the process moves from Step 200 to Step 230 to store "no bell sound" in the RAM 9 and then moves from Step 231 to Step 206. Telephone A is off-hook, so proceed to Step 220 and telephone B
Is separated from the line and Steps 221-224 are looped.

When the telephone number is transmitted by the dial pulse transmission circuit 19, the process proceeds from Step 222 to Step 229, the telephone number is transmitted, the line is captured, and the process returns to the loop of Steps 221 to 224 described above. During this time, the telephone A can communicate with the outside line.

If you push down the communication button of the facsimile machine, Step22
Move from 1 to Step 225 and switch the line to the modem side.
Since the original is set in Step226, Step2
Moving to 27, the facsimile transmission procedure is performed and the flow is ended.

External line transmission mode from telephone A The flow starts by taking telephone A off hook. Since there is no incoming call bell, move from Step 200 to Step 230 and memorize "No bell sound" in RAM9, then from Step 231 to Step 2.
Move to 06. Phone A is off-hook, so Step
Proceed to 220, disconnect telephone set B from the line, and perform steps 221-224.

Since the call is an extension call from the telephone A, the hold / extension button of the operation unit 11 is pushed, and the process proceeds to Step232, the telephone B is switched to the DC voltage source side, and the DC voltage source 27 is changed to, for example, 16H in Step233.
Modulates with z to generate a pseudo bell sound. Move to Step234,
"Calling phone B" is stored in RAM9, and the process proceeds to step 206. Phone A is on-hook and RAM9 reads "Phone B"
Since "calling" is stored, Step 208 to Step 206
The loop to is repeated. Telephone B that called the extension
Off hook, the process moves from Step 208 to Step 211, the pseudo bell sound is stopped, the telephone A is switched to the DC voltage source side in Step 212, and the speaker 16 is turned on in Step 213. Then, the loop of Steps 214 and 215 is entered. During this loop,
The call from the called telephone B can be heard from the speaker. As a result, the off-hook of the telephone set B in Step 208 can be confirmed, and if the telephone set A goes off-hook, the process proceeds to Step 217, the speaker 16 is turned off, and the extension call is performed in the loop of Steps 217 and 218. If any phone goes on hook, the flow ends.

If the telephone set B goes on-hook during the loop of Steps 214 and 215, the process proceeds to Step 216, the speaker 16 is turned off, and the flow ends.

Extension call mode from the telephone B to the telephone A The flow starts by taking the telephone B off-hook. Since there is no incoming call bell, move from Step 200 to Step 230 and memorize "No bell sound" in RAM9, then from Step 231 to Step 2.
Move to 06. Since Phone A is on-hook, Step
The process proceeds to step 207, and since "calling for telephone B" is not stored in the RAM 9, the process proceeds to step 209. Since the telephone B is off-hook, the procedure proceeds to Step 210, the telephone A is separated from the line 4 and switched to the DC power source side, and the "no bell sound" stored in the RAM 9 at Step 230 causes the transition from Step 300 to Step 400 and Step 401. Loop. When the ten key of the telephone B is pressed here, the operation proceeds to Step 402. If the content of the ten key is "00" indicating an extension call, the operation proceeds to Step 405 and the telephone B is switched to the DC voltage source side. Step406
Then, the pseudo bell sound as described above is generated by the DC voltage source 27, and the off-hook of the telephone A is waited for in the loop of Steps 407 and 408. If the telephone A does not respond, if the telephone B is hooked on, the flow is ended from Step 408.

If the telephone set A goes off-hook, the process proceeds to Step 409, the pseudo bell sound is stopped, and the extension call is made in the loop of Steps 410 and 411. If any phone goes on hook, the flow ends.

External call reception mode by the telephone A There are a case where the facsimile apparatus is set in the manual reception mode and a case where the facsimile apparatus is set in the automatic reception mode and the telephone A is off-hook within a predetermined number of bells. The flow starts with telephone A off-hook.

In the former case, the process proceeds from Step 200, 201, 202 to Step 206. In the latter case, the process proceeds from Step 203 in Step 206 to Step 206. Step 220 because phone A is off-hook
Then, the process proceeds to, the telephone set B is separated from the line, and steps 221 to 224 are looped. During this time, the telephone A can communicate with the outside line. Step 22 if phone A goes on hook at the end of the call
