Description

TECHNICAL FIELD The present invention relates to a communication device having a calling function.

[Prior Art] Conventionally, in a device of this type, for example, a telephone having a redial function or a facsimile device, a redial circuit is uniformly determined, and a line is not connected to a partner even after the redialing of a predetermined number of times is completed. And the calling operation ends.

[Problems to be Solved by the Invention] However, when making a call, a large number of redials may be required or a small number of redials may be required depending on the other party or purpose of use. is there.

For this reason, if the number of redials is uniformly set, there will be a lot of waste in the designation of the call destination and the redial operation.

[Means and Actions for Solving Problems] According to the present invention, when one-touch dialing is performed, the number of times the one-touch dial button is operated or time is used. The number of re-calls can be set by the number or time of operating the speed dial buttons, or in the case of other dials, by the number or time of operating the start key after inputting the destination number from the ten key.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of the facsimile machine of this embodiment. In FIG. 1, reference numeral 1 is a crystal oscillator that generates a reference clock for the entire apparatus.

The output clock of the crystal oscillator 1 is given as a reference clock to a desired CPU (Central Processing Unit) 2 composed of a microprocessor element or the like. CPU2 uses data and address bus to ROM3, RAM4, timer 5, PPI (Pro
gramable Parallel I / O) 6,7,10 and UPI (peripheral CPU)
It is connected to 9,11,12 via rose lines. The CPU2 controls the whole device. Further, the CPU 2 encodes and decodes the image data.

Reference numeral 13 denotes a DMA controller, which controls the memory for reading and writing data such as ROM3 and RAM4.

 The UPI 9 controls driving of originals and recording paper.

The UPI 11 controls the parallel-serial converter 25 and the recording system of the thermal head.

The UPI 12 controls the key input switch 31 and the liquid crystal display LCD32.

A modem 14 modulates and demodulates image data and transmits and receives procedure signals for facsimile communication procedures.

Reference numeral 15 is a network control unit (NCU) for switching connection of the line 33 to the telephone 34 side or the modem 14 side.

Reference numeral 16 is a dialer, which sends a dial signal to the line 33 in accordance with the telephone number data of the communication destination output from the CPU 2 via the PPI 7.

Reference numeral 18 is a speaker drive circuit, and 19 is a speaker, which outputs a signal from the line 33 as the relay 8 is turned on.

Further, FIG. 2 is a view showing the operation display section of this embodiment, and the operation display section of this embodiment comprises a key input section 31 and a display section 32.

Next, the operation of facsimile transmission and reception of this embodiment will be described.

 First, the facsimile transmission operation will be described.

First, the operator sets the original to be sent to the reading section, designates the other party to call by using the ten-key 31d in FIG. 2, the one-touch dial button 31k, or the abbreviated button 31i and the ten-key 31d, and the dialer 16 makes a call. Operate the line to connect to the other side (call the line to connect, but if the line is not connected to the other side, redial will be performed up to the set number of times) and key input section
When the start button 31a of 31 is turned on, the CPU 2 starts facsimile transmission on condition that the document sensor 42 detects the document. CPU2 is connected when the fax transmission starts
33 is switched from the telephone 34 side to the modem 14 side, and the CCITT recommended facsimile communication procedure is performed to determine the communication mode.

Then, when the communication mode is determined, the CPU 2 outputs a read drive instruction signal of the read motor 38 to the UPI 9, the UPI 9 outputs the read drive signal to the pulse driver 36 when the read drive instruction signal is input, and drives the read motor 38, and the CCD The read image signal read by the (solid-state image sensor provided in a line) 41, converted into a serial digital signal by the analog ABC circuit 40, and converted into a parallel signal of a predetermined bit number by the serial-parallel converter 3 is read by the CPU 2. Input sequentially, MH method (modif eyed Huffman method) or
The MR system (modifid read system) is encoded and output to the modem 14. The modem 14, which receives the encoded image signal, modulates the image signal at the transmission rate determined by the facsimile procedure and outputs it to the line 33. When the original of one page is completed, the facsimile procedure is performed. At this time, if the original sensor 42 detects the next original, a facsimile procedure signal of the presence of the next original is transmitted to the other side, and if there is no next original, the original is finished. The facsimile transmission procedure signal is transmitted, and the facsimile transmission is terminated.

 Next, the case of reception will be described.

CPU2 via call signal from line 33 and NCU15, PPI6
When it detects, the line 33 is switched from the telephone 34 side to the modem 14 side, and the CPU 2 sends a called station identification signal (CED signal) indicating that it is a non-voice terminal via the modem 14, and then the function information of the own device. The digital identification signal (DIS) that is a signal is transmitted, and the NSS signal, TSI, which is a facsimile procedure signal from the other side,
Receives the digital command signal (DCS signal) and sets the communication mode based on the procedure signal. At this time, if the data return instruction is set to the predetermined bit of the NSS signal, the image data to be received thereafter is recorded in the RAM 4 while being stored.

The received image signal is demodulated by the modem 14, decoded by the CPU 2, converted into a serial digital signal by the parallel-serial converter 25, and recorded on the thermal paper by the thermal head 43. At this time, the recording motor 37 for conveying the thermal paper is driven by the UPI 9.

When the recording of the received image signal is completed in this way, the line is normally opened and the reception operation is completed.

The above is the general operation of facsimile transmission and reception, but in this embodiment, re-calling (redial) will be described in detail.

FIG. 3 is a flow chart showing the control operation when the CPU 2 of the present embodiment makes a call.

First, in step s1, it is determined whether or not there is a key input, and if there is a key input, the process proceeds to step s2, and if there is no key input, the process proceeds to step s8.

It is determined that there is a key input in step s1, and step s2
In step s2, the timer T1 (the timer time is about 5 seconds, but it is not limited to 5 seconds and can be arbitrarily set by the operator) is set and the timer is started.
Then, the key entered at steps s3, s4, s5, s6 is the one-touch dial button 31k, the abbreviated button 31i, or the numeric keypad.
31d or the start key 31a is discriminated. If the input key is not one of them, the process proceeds to step s7, the process corresponding to the input key is performed, and then the process returns to step s1.

If it is determined that the key entered in step s3 is the one-touch dial button 31k, the operation proceeds to step s10 and the dial number data corresponding to the entered one-touch dial button is read from the one-touch dial area of RAM4 and stored in the dial buffer. Set (store). Then, in step s11, the redial counter is incremented and the process returns to step s1.

The key entered at step s4 is the speed dial button.
If it is determined to be 31i, the process proceeds to steps s12 and s13, the redial counter is incremented, the speed dial flag provided in the RAM 4 is set, and then the process returns to step s1.

When it is determined that the key input in step s5 is the ten-key 31d, the process proceeds to step s14, and it is determined whether or not the abbreviated diamond flag is set to determine whether or not it is the ten-key after the abbreviated button 31i is input. . If it is determined in step s14 that the speed dial flag has been set, step s15 follows.
In 15, it is judged whether the abbreviated number has been entered by the entered numeric keypad. When the abbreviated number is entered, the operation proceeds to step s17 and the dial number data corresponding to the entered abbreviated number is read from the abbreviated dial area of RAM4. After reading out and storing in the dial buffer, the process returns to step s1. If the input of the shortened number is not completed in step s15, the numeric keypad entered in step s16 is set in the shortened number buffer and the process returns to step s1.
On the other hand, if it is determined in step s14 that it is not the numeric keypad after the input of the shortening button 31i, the process proceeds to steps s18 and s19, and step s18
Numeric keypad flag (provided in RAM4) that indicates dial input using the numeric keypad 31d in
Is set, the numeric keypad input at step s19 is stored in the dial buffer, and the process returns to step s1.

The key entered in step s6 is the start key 31a.
If it is determined that the numeric keypad dial flag is set in step s20, if the numeric keypad dial flag is set, the redial counter is incremented in step s21 and the process returns to step s1. If the numeric keypad dial flag is not set in step s20, it is determined in step s22 whether dial number data is stored in the dial buffer. If dial number data is stored, the process proceeds to step s24 and the dial number is stored. If the data is not stored in the dial buffer, proceed to step s23 to determine whether the circuit is connected. If the line is connected, move to facsimile communication and if the line is not connected. Move to copy or recording paper feed.

As described above, in the case of one-touch dial, the number of redials is set depending on the line on which the one-tatch dial button 31k is pressed.
The number of redials is set according to the number of times i is pressed,
Start button 3 when dialing with numeric keypad 31d
The number of dials is set according to the number of times 1a is pressed.

On the other hand, if there is no key input in step s1, the process proceeds to step s8 and it is determined whether the timer T1 has timed out. This is for determining whether or not there is the next key input until the time T1 has elapsed after the previous key input, and if there is no next key input even after the time T1 has elapsed, the process proceeds to step s9. Then, in step s9, it is judged whether or not the dial number data is stored in the dial buffer, and if the dial number data is stored in the dial buffer, the process proceeds to step s2 to make a call, and the dial number data is stored in the dial buffer. If it is not stored in the far, the process ends, and if there is a key input again, the process starts from step s1.

In step s24, after the line 33 is captured, the dial number data of the dial buffer is read and the dialer 16
The tone dial signal corresponding to the dial number read by is sent to the line (calling operation is performed). And
At step s25, set timer T2 (about 35 seconds, but the operator can set the time arbitrarily), and
In s26 and s27, it is determined whether or not the line is connected to the partner before the timer T2 times out. To determine whether the line at step s26 has been connected to the other party,
Judgment is made based on whether the CU 15 detects the polarity reversal of the line 33. The determination as to whether or not the line is connected is not limited to the detection of the polarity reversal of the line. For example, in a facsimile device or the like, the determination may be made based on whether or not the procedure signal from the partner is detected. Timer s in step s26
If it is determined that the line has been connected to the other party before 2 times out, it shifts to facsimile communication, and if the timer T2 times out (switches to communication mode in case of a telephone), if the line is not connected, step s27 to step s
Proceed to 28.

In step s28, it is judged whether or not the count value of the redial counter is 0. If the count value of the redial counter is 0, the process proceeds to step s29, and the display 32 indicates that the line is not connected to the other party. If the count value of the redial counter is not 0, the line 33 is opened, and then the timer T3 is set at step s30 (1 or 2 minutes, but the time can be set arbitrarily by the function button 31c and the numeric keypad 31d). If it is determined that the timer T3 has timed out in step s31, step s32
Decrement the redial counter at step s24
Return to and redial.

As described above, according to the present embodiment, the number of redials is set by the number of times the key is pressed for dialing, but as another embodiment, the one-touch dial button 31k, the shortening button 3
1i, the number of redials may be set depending on the pressing time of the start button 31a. When the number of redials is set by this pressing time, the redial counter is incremented every 1 second of pressing time.

In the present embodiment, the facsimile device is described as an example, but the present invention is not limited to the facsimile device, but can be applied to all communication devices such as a telephone, a teletex, a telex, a word processor communication and a personal computer communication.

[Effect] As described above, according to the present invention, a one-touch dial,
In the case of abbreviated dialing or other dialing, the user can easily set the number of re-calls depending on the other party or the purpose of calling.
