Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile facsimile machine with a redial function.

[0002]

2. Description of the Related Art Conventionally, a facsimile machine for an automobile has a network control unit (NCU) interposed between a radio of a car telephone and a telephone so that the radio and the telephone are separated from each other during facsimile transmission. Images are transmitted by connecting the main unit.
Means for detecting a serial signal between a car radio and a telephone are disclosed in, for example, JP-A-2-57051, JP-A-2-57052, JP-A-3-247065, and JP-A-3-265348. Etc.

Conventionally, when a user desires facsimile transmission, a manuscript is set, a telephone is called from a telephone, and after confirming that the other party is connected, the radio and the facsimile main body are connected.

[0004]

However, conventionally, when a user makes a call from a telephone, if the other party is absent or busy, the user hangs up once and dials again. I had to make a phone call.

Therefore, in the present invention, in a car telephone, a serial signal from the telephone to the radio is stored,
The challenge is to be redialable.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, means taken by the present invention are as follows: a transmission means for transmitting, to a facsimile main body, a calling signal made by calling a serial signal line from a telephone. , A judgment means for judging whether or not the line is connected as a result of calling from the wireless device, and a calling signal is read from the facsimile main body when the line is not connected, and this calling signal is serialized to the wireless device. And a re-transmitting means for transmitting to the signal line.

[0007]

According to the above means, when a call is made from the telephone, a call signal is sent to the other party via the radio. At this time, the transmission means of the network control unit reads the calling signal issued by the telephone and sends it to the facsimile body.
When the other party receives this calling signal, the line is connected. However, the line is not connected when the other party is busy. In this case, even after the telephone is placed, the retransmitting means reads the calling signal from the facsimile body and sends the calling signal to the serial signal line to the wireless device. Therefore, even if the user does not redial from the telephone, the network control unit and the facsimile main body automatically redial and, if connected, the image is transmitted.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a facsimile machine 5 is interposed between a radio 1 and a telephone 2 of a car telephone. The facsimile device 5 comprises a facsimile main body 3 and a network control unit (hereinafter referred to as NCU) 4.

A relay 41 for switching between is provided. In addition, NCU4
A serial input / output device (hereinafter referred to as a serial I / O) 42 connected to the up serial signal line and the down serial signal line from the wireless device 1 and an up serial signal line and a down serial signal line from the telephone 2 were connected. It has a serial I / O 44. Both serial I / Os 42 and 44 transmit / receive to / from a central processing unit (hereinafter referred to as CPU) 43. The CPU 43 has an internal memory 45.
Have. The CPU 43 receives the serial signal from the telephone 2 via the serial I / O 44 and
It is sent to the serial signal line to the wireless device 1 via 42.
In addition, the serial signal from the wireless device 1 is transferred to the serial I / O 4
2 via the serial I / O 44 and sends it out to the serial signal line to the telephone set 2. At this time, the CPU
Reference numeral 43 selects a serial signal required for the facsimile main body 3 and transmits it to the system control unit 37 of the facsimile main body.

The system control unit 37 of the facsimile main body sends a signal to the relay 41 in the NCU 4. In a normal state, the relay 41 connects the voice lines of the wireless device 1 and the telephone set 2. Radio 1 by driving relay 41
And the facsimile main body 3 is connected.

When a user sends an image by using a facsimile, the user uses the telephone 2 to call the other party, confirms that the call is connected, and then operates the operation / display unit 36 of the facsimile main body. .. By this operation, the system control unit 37 drives the relay 41, and the voice line of the wireless device 1 and the facsimile main body 3 is connected. The facsimile main body 3 reads an image by the image reading unit 31, and sends the image signal to the wireless device 1 through the communication control unit 35 and the modem 38 through a voice line.

On the other hand, when facsimile communication is requested from the other party, the CPU 43 intercepts the serial signal from the wireless device 1, recognizes that the request is for facsimile communication, and sends a signal to the system control unit 37 of the facsimile main body. To send. The system control unit 37 drives the relay 41 of the NCU 4 to connect the wireless device 1 and the voice line of the facsimile main body 3. The image signal received by the wireless device 1 is sent to the modem 38 of the facsimile main body 3 through a voice line. The modem 38 demodulates the image signal and sends the image data to the communication control unit 35. The communication control unit 35 sends a signal to the image printing unit 32 to print an image.

When a user sends an image by using a facsimile and the calling party is not present or the calling party is busy, the hook of the telephone set 2 is once placed.
At this time, the CPU 43 operates according to the flowchart shown in FIG. In the flowchart of FIG. 2, only the dial call signal of the serial signals is controlled, but a routine for controlling the facsimile main body 3 in accordance with another serial signal may be added. In the following routine, serial signals other than the dial call signal are serial I / O signals.
When it reaches 42 or 44, the serial signal is sent to the serial I / O 44 or 42 at any time.

The CPU 43 has a counter C1 and a timer T0.
And a timer T1. The timers T0 and T1 are timers that are decremented over time. In FIG. 2, the CPU 43 determines in step 60 whether or not a dial call signal has come to the serial I / O 44 on the telephone 2 side. If the dial call signal does not reach, step 60 is repeated. The dial call signal includes a dial signal, a station number and a dial completion signal. When these three signals arrive continuously, it is considered that there is a call. When the dial call signal arrives, the dial call signal received in step 61 is stored in the internal memory 45. Next, in step 62, a dial call signal is sent to the serial I / O 42 on the radio 1 side. As a result, a dial call signal is sent from the wireless device 1. Next, in step 63, a dial call signal is sent to the system control unit 37 of the facsimile main body 3. The facsimile main body 3 stores the dial call signal received by the system control unit 37 in the memory 39. Also, the value 3 is set in the counter C1. next,
In step 65, the T0 timer is set to 30 seconds.
In step 66, it is determined whether or not the talk ON display ON signal has come to the serial I / O 42 of the wireless device 1. The call-on display ON signal is issued during communication after the called party picks up the handset. If no ON signal is displayed during the call, it is judged in step 69 whether the T0 timer has ended. T
When the value of the 0 timer is 0 seconds or less, it is determined that the timer has ended. T
If the 0 timer has not expired, the process returns to step 66. 3 according to the judgments in steps 66 and 69.
If the display ON signal during a call arrives within 0 seconds, step 6
7 is executed, and if the talk ON display ON signal does not come within 30 seconds, step 70 is executed. In step 67, the dial calling signal stored in the internal memory 45 of the CPU 43 is cleared. As a result, the transmission of the dial call signal to the wireless device 1 is stopped. Next, at step 68, the system control section 37 of the facsimile main body 3 is instructed to transmit the document. When the facsimile main body 3 receives this instruction, it drives the relay 41 to send an image signal from the modem 38 to perform facsimile communication. Then step 73
At, an instruction is sent to the system control unit 37 to clear the dial call signal stored in the memory 39 of the facsimile main body 3. Then, the process returns to step 60. On the other hand, in step 70, the dial call signal stored in the internal memory 45 of the CPU 43 is cleared. Next, the counter C1 is decremented by 1. Next, at step 72, it is judged if the value of the counter C1 has become zero. If the counter C1 is 0, in step 73, an instruction is sent to the system controller 37 to clear the dial call signal stored in the memory 39 of the facsimile main body 3. If the counter C1 is not 0, the T1 timer is set to 60 seconds in step 74, and the process waits until the T1 timer ends in step 75. When the T1 timer expires,
Next, at step 76, the system control unit 37 of the facsimile main body 3 is instructed to read the dial calling signal stored in the memory 39 and send it to the CPU 43, and the dial calling signal is sent from the facsimile main body 3. receive. Next, in step 77, the serial I /
The dial call signal received from the facsimile main body 3 is sent to O42. As a result, a call is automatically made via the wireless device 1 without operating the telephone 2. Then, the process returns to step 65.

In the above routine, when the first call is made and the other party cannot be reached (when there is no ON signal during the call display within 30 seconds), redialing is automatically performed twice every 60 seconds. .. The values initially set in the counter C1 and the timers T0 and T1 are set to three times, 30 seconds and 60 seconds, respectively, in the present embodiment, but may be appropriately changed depending on the usage situation.

In the above routine, step 63 is
It corresponds to a transmitting means for transmitting a calling signal, which is originated from the telephone 2 to the serial signal line, to the facsimile main body 3. Steps 66 and 69 correspond to a judgment means for judging whether or not the line is connected as a result of calling from the wireless device 1. Further, steps 76 and 77 correspond to the re-transmitting means for reading the calling signal from the facsimile main body 3 when it is judged that the line is not connected and sending the calling signal to the serial signal line to the wireless device 1.

In this embodiment, when the user makes a call from the telephone, if the other party is absent or busy, even if the user hangs up once, the user automatically dials again. If you make a phone call and connect, the image of the manuscript will be sent automatically. Therefore, redialing can be automatically performed even in a car phone.

[0019]

According to the present invention, even a car telephone can be redialed automatically when the other party is absent, which is convenient.
