Abstract

PURPOSE:To attain automatic reception of facsimile communication even when the operator leaves its seat while the mode is set in the manual reception mode by comparing number of times of a bell signal at the arrival of a call with a password code data set in advance and setting the mode into the automatic reception mode when they are coincident. CONSTITUTION:A telephone set 3 is dialed from a visiting place and number of times of ring back tone signals sent from an exchange at the start of call is counted and when a ring back tone signal of the same number of times as a password code number stored in advance in a memory 6 is confirmed, the handset is hooked on to interrupt the line. In the case of the password code '456', since the initial number is '4', the handset is hooked on when 4 times of ringback tone signals are confirmed in this case. A control circuit 4 detecting the incoming call during this time uses a counter 8 to count the bell signal till the bell signal is stopped and '4' of the content of the counter 8 is written in the memory 6. Similarly, the coincidence with the password code '456' is confirmed further. Thus, the facsimile equipment is received automatically.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to facsimile devices.

(B) Conventional technology In general, facsimile machines have a manual reception mode in which the telephone responds when an incoming call is received, and an automatic reception mode in which the reception operation is automatically started. is configured to be set to (
For example, in 1982, when a telephone line was provided exclusively for a facsimile machine, it was normally set to automatic reception mode and used for constant facsimile communication; If you want to use it as both a phone call and a facsimile machine, set it to manual mode.When you receive an incoming call, the phone will answer the call, and if the other party announces that they are sending a facsimile, pressing the reception key will send the facsimile. It switches to the device side and receives it.

(c) Problems to be Solved by the Invention As mentioned above, if the manual reception mode is set, only the telephone will respond, so if you forget to switch to the automatic reception mode when you go out and are absent, was unable to receive faxes while I was away.

(d) Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and includes means for counting the number of bell signals at the time of incoming calls, means for storing the count results, and stored data. and control means for controlling the automatic reception mode to be set if a match is detected as a result of the comparison.

(E) Function Since the present invention is configured as described above, the facsimile machine can be set to manual reception mode by making a call from outside and repeating the operation of hanging up after the ringtone rings a predetermined number of times. can be set to automatic reception mode.

(f) Example Embodiments of the present invention will be described below based on the drawings.

Reference numeral (1) denotes a transmitting/receiving section for transmitting and receiving facsimile signals, and since it has a well-known configuration, detailed explanation will be omitted. (2
) is a line switching circuit that switches and connects the telephone set (3) and the transmitter/receiver (1) to the telephone line (L), and is composed of a switch circuit (2'). (4) is a control circuit composed of a microprocessor, which controls each part according to a built-in processing program. (5) is a keyboard for giving various operation commands to the control circuit (4), and is composed of a transmit key, a receive key, a numeric keypad, a mode key, etc. (6) is a memory in which data processed by the control circuit (4) for transmission and reception, or data inputted from the keyboard (5), etc., is stored, and writing and reading of data is performed by the control circuit (4).
4) is carried out under the control of (7) is a switch circuit (
The bell signal detection circuit is connected to the telephone line fL) through the telephone line fL), which outputs one pulse output to the counter (8) for each bell signal, and outputs an H signal during the duration of the bell signal.
Control the level signal! (The counter (8) counts the pulses from the bell signal detection circuit (7) and supplies the count result to the control circuit (4).The switch of the line switching circuit (2) The circuit (2°) is normally switched to the telephone (3) side in standby mode, and the control circuit (4) is switched to the telephone (3) side when starting facsimile communication.
is switched to the transmitting/receiving section (1) side under the control of.

Next, the operation of the present invention having such a configuration will be explained based on the flowchart shown in FIG.

First, a password to be used when switching to automatic reception mode from outside the home is entered using the numeric keys on the keyboard (5) and stored in the memory (6). It is assumed that the password code "R456" is stored.

Also, when in automatic reception mode, the line switching circuit (
The number of bell signals when the switch circuit (2°) in 2) is switched to the transmitter/receiver (1) side is input using the numeric keypad of the keyboard (4) and stored in the memory (6). Assume that "3" is stored in the memory (6) so as to respond with three bell signals.

Therefore, in the standby state, the control circuit (4) repeatedly performs the processing of steps (Sl) to (S4), and when there is an incoming call, the telephone (3) rings with a bell signal to notify the incoming call. The control circuit (4) detects the incoming call in step (Sl) based on the output from the bell signal detection circuit (7), clears the counter (8) in step (S5), and then proceeds to step (S6) to clear the counter. (8) to start counting the bell signal, then step (
Proceed to step S7), fetch the value of the counter (8), and store it in the memory (
6), it is determined whether the predetermined number of times "3" stored in advance has been reached, and if it has not reached the predetermined number "3", step (S6) is performed.
) and continues counting, and when it is detected that the predetermined number of times has been reached, the process advances to step (S8) to determine whether or not the automatic reception mode is set. If the automatic reception mode is set, proceed to step (S+41) and control the switch circuit (2') of the line switching circuit (2) to connect the telephone line (L) to the transmitter/receiver (1). As a result, the ringing of the telephone (3) is stopped, and the reception operation Δ is performed in step (S15).When the reception is completed, the control circuit (4) switches to step (SI?). The advance switch circuit (2'') is controlled to switch the telephone line (L) to the telephone (3) side and return to the standby state.

On the other hand, if it is determined in step (S8) that the manual reception mode is set, the process proceeds to step (S9) and checks the output of the bell signal detection circuit (7) to determine whether the bell signal has stopped. Determine whether or not. If the bell signal continues, the process advances to step (S6) to continue counting the bell signal, but if the bell signal has stopped, the value of the counter (8) is read in step (SIO) and stored in the memory ( 6). When written to memory (6), the data written to memory (6) in step (Sll) and
It is determined whether or not it matches the preset password r456J. If it does not match, it returns to the standby state, but if it matches, it goes to step (Sll).
After proceeding to step (S12) and changing the mode from manual reception mode to automatic reception mode, in step (S13) the counter (8) written in the memory (6) is
) value and return to standby mode.

Therefore, if automatic reception mode is set,
When the incoming bell signal is received three times, step (S8)
The process then proceeds to step (S14) and reception is automatically started.

On the other hand, if the manual reception mode is set, the telephone (3) will ring when an incoming call is received, and if the handset of the telephone (3) is picked up, the line will be closed and the telephone will be in a talking state.

Since the generation of the bell signal is stopped when the handset goes off-hook, the control circuit (4) that detects the stoppage of the bell signal in step (S9) proceeds to steps Since a match cannot be obtained, the state returns to the standby state from step (Sll). Therefore, during the call, the control circuit (4) is in a standby state and repeats the processing of steps (S1) to (S4).

If the other party announces that they wish to perform facsimile communication during the call, when the receive key on the keyboard (5) is operated, the control circuit (4) that detected the receive key signal in step (Sl) ) and start the reception operation in the same way as described above.

Next, we will explain how to set the automatic reception mode from the outside when you go out with the manual reception mode set.

In this case, dial the telephone (3) from outside, count the number of ringback tone signals sent from the exchange at the start of the call, and dial the same number of rings as the pin code number stored in the memory (6) in advance. After confirming the backtone signal, go on-hook and hang up. All pin code r
Since the initial value of 456J is "11", it goes on-hook after confirming the ringback tone signal four times.

The control circuit (4) that detected the incoming call during this time counts the bell signals with the counter (8) until the bell signals stop. ) value is "4", and the value "4" of the counter (8) is stored in the memory (6) at step (SIO).
”. After that, do the same thing and call tii (3) from outside.
) twice and write the data "5" and "6" in the memory (6). When "6" is written as a result, the preset PIN code is entered in step (Sll). Since a match with "456" can be detected, the control circuit (4) proceeds to step (S12>) and sets the automatic reception mode, and then writes the value of the counter (8) of the memory (6) in step (S131). Clear the area and return to standby mode.Although I set the entire PIN code to 3 digits, you can set it to 2 digits or even more digits, then dial the destination using the telephone (3). After confirming the response from the destination facsimile machine, when the send key on the keyboard (5) is operated, the control circuit (4) that detected the key signal in step (Sl) proceeds to step (S18) and switches the line. Control the circuit (2) to connect the telephone line (L) to the transmitting/receiving section (1), perform the transmitting operation in step (S19), and when the end is detected in step (S20), proceed to step (S1?). (G) Effect of the Invention As mentioned above, even if the facsimile machine of the present invention is set in manual reception mode and goes out, it can be set to automatic reception mode by dialing from outside. This has the effect of automatically receiving facsimiles.
