Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a transmission control system for a car telephone facsimile device.

[Prior Art] In recent years, car phone facsimile devices that use car phone devices as transmission means have been put into practical use.

With car phone equipment, if the car equipped with it moves beyond a certain distance from the wireless base station, or if the car enters a tunnel etc. and the radio field strength becomes extremely low, signal transmission and reception may become extremely unstable. Unable to send or receive signals.

Therefore, when the signal strength drops below a certain value, it is assumed that the vehicle is out of range of the car phone service, and an out-of-range signal is output, thereby notifying the operator that it is out of the service area. .

Now, even when using a car phone facsimile device, if the car moves out of the car phone service area, this out-of-service signal is output, and when such a situation occurs, the image information transmission that was being carried out at that time is interrupted. do.

For this reason, conventionally, if you go out of the car phone service area while transmitting image information using a car phone facsimile device, the next time you return to the car phone service area, you have to call the destination again. It is necessary to transmit image information, which may cause a heavy burden on the operator.

[Objective] The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a transmission control method for a car phone facsimile device that can improve the usability of the car phone facsimile device.

[Configuration] In order to achieve this object, the present invention includes a selection signal storage means for storing a destination selection signal, and when an out-of-range signal is outputted from the car phone device during transmission, the image information is transmitted at that point. When this is interrupted and the out-of-range signal is turned off, a call is made to the destination of the selection signal stored in the selection signal storage means.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a car telephone facsimile device according to an embodiment of the present invention.

In the figure, a facsimile device 1 equipped with an image information generating/recording function is connected to a car phone device 2 via an interface circuit 3, and a handset 4 of the car phone device 2 is connected to a car phone device 2 via an interface circuit 3. and is connected to the car telephone device 2.

In the facsimile device 1, a system control unit 10 is for controlling the entire facsimile device 1, and a memory 11 is for storing selection signals inputted from the handset 4 and the like.

The scanner 12 is for reading a transmission document at a predetermined resolution, and the plotter 13 is for recording and outputting an image at a predetermined resolution.

The encoding/decoding unit 14 encodes and compresses the transmitted image signal and decodes the received image information into the original image signal, and the operation display unit 15 is used to operate the facsimile device. Yes, the communication control unit 16 is for performing facsimile transmission control procedure processing, and is for controlling the modem 1.
7 modulates and demodulates digital data. Input/output signals of the modem 17 are exchanged with the car telephone device 2 via the interface circuit 3.

These system control unit 10, memory 11, scanner 1
2. Plotter 13, encoding/decoding section 14, operation display section 1
5 and the communication control unit 16 exchange necessary data with each other via the system bus 18.

The car telephone device 2 includes a transmission line Lt for inputting a transmission signal, a reception line Lr for outputting a reception signal, and an off-hook line Lo for detecting off-hook of the handset 4.
, a signal line 1 for outputting an out-of-range signal to notify that the car telephone device 2 has moved out of a certain range based on the ground base station; and a selection signal for specifying the destination is input. A signal line L2 for this purpose is output to the outside.

Of these signal lines, the transmission line Lt and the reception line Lr are switched and connected to either the handset 4 or the modem 17 of the facsimile machine 1 via the interface circuit 3, and the off-hook line Lo, the signal line L1, and The signal line L2 is connected to the handset 4 and also to the system control section 10 of the facsimile machine 1 via the interface circuit 3.

Therefore, the car telephone device 2 includes a handset 4,
Alternatively, when either the handset 4 or the facsimile device 1 enters an off-hook state due to input/output of a transmission/reception signal to either the facsimile device 1, the car telephone device 2 becomes an off-hook state. Also, handset 4
The off-book status of is also input to the system control unit 10 of the facsimile machine 1.

Further, a selection signal outputted from either the handset 4 or the system control unit 10 of the facsimile device 1 is input to the car telephone device 2, and a call operation is performed. In addition, the selection signal output from the handset 4 is
The data is also input to the system control unit 10 of the facsimile machine 1 via the interface circuit 3 .

Furthermore, the out-of-range signal output from the car telephone device 2 is
It is output to the handset 4 and the system control section 10 of the facsimile machine 1. This also causes the out-of-service area indicator lamp of the handset 4 to light up.

With the above configuration, when this car phone facsimile device transmits image information to another car phone facsimile device,
First, the operator picks up the handset 4 with the document to be transmitted set on the scanner 12, and inputs the dial number of the destination using the numeric keypad (as shown) on the handset 4.

When the operator connects to the destination car phone facsimile device and automatically answers, the operator turns on the start key of the car phone facsimile device on the own terminal side to start the transmission operation, and returns the handset 4 to its original position.

When the system control unit 10 of the facsimile machine 1 detects that the handset 4 goes off-hook, it performs the transmission operation shown in FIG. 2.

The system control unit 10 first turns on the off-hook line LO to maintain the off-footer state (process 101), and then stores the selection signal inputted by the operator from the handset 4 in the memory 11 (process 102).

Then, when the destination car phone facsimile device automatically responds, a prescribed car phone facsimile transmission control procedure is started, and the process shifts to the image information communication state (process 103).

In the communication state of this image information, the period (
(when the result of judgment 104 is NO), the out-of-range signal is monitored for being output (No loop of judgment 105), and the image information communication is completed without the out-of-range signal being output. In this case, the result of judgment 104 is YES, so the process ends normally, and the off-hook line LO is turned off to restore the line.

On the other hand, if the car enters a tunnel or goes outside the car phone service area during image information communication and the out-of-service signal is output on, the result of determination 105 becomes YES.

As a result, the system control unit 10 controls the off-hook line Lo.
is turned off to restore the line, and the operation display unit 15 notifies the operator of the interruption of image information transmission (process 106). Further, if there is a transmission document that is being read at this time, it is forcibly ejected (process 107), and a guidance message prompting the user to set the transmission document again is displayed on the operation display section 15.

From then on, the system control unit 10 monitors the return to the car phone service area by turning off the out-of-service signal (No loop in judgment 108).

For example, when the car exits the tunnel and returns to the car phone service area and the out-of-service signal is turned off and the result of judgment 108 becomes YES, the off-hook line Lo is turned on to switch to the off-hook state (process 109), and the result is stored in the memory 11. The selected selection signal is extracted and outputted to the car telephone device 2, and a call is made to the same destination again (process 110).

As a result, when a call can be made to the destination car telephone facsimile device, image information processing from step 103 is executed.

In this way, in this embodiment, when the user goes out of the car phone service area, the transmission of screen information is interrupted;
When you return to a location outside of the car phone service area, you can re-call the same destination and send image information again.

Therefore, the operator's effort when transmitting image information while the vehicle is moving can be significantly reduced. Furthermore, since the call is automatically re-done, there is no need for the operator to make a call even when the car phone is busy.

[Effects] As explained above, according to the present invention, the selection signal storage means for storing the destination selection signal is provided, and when the out-of-range signal is outputted from the car phone device during transmission, the image information is transmitted at that point. When this is interrupted and the out-of-range signal is turned off, the destination of the selection signal stored in the selection signal storage means is called, so that the usability of the car telephone facsimile device can be improved.
