Abstract

PURPOSE:To prevent the operator of a telephone system from being troubled with incoming from a facsimile equipment by driving an off-hook relay by a control part to disconnect a telephone line at the time when a tone detector detects a facsimile control signal to send it. CONSTITUTION:When the facsimile control signal is transmitted in a prescribed time, this signal is detected by a tone detector 6, and the detector 6 outputs the detection result to a control part 11. When receiving the signal indicating the reception of the facsimile control signal from the tone detector 6, the control part 11 judges the other party as a facsimile equipment and drives a tone sender 14 to send a called terminal discrimination CED signal and sends a line disconnecting instruction DCN through a MODEM 12 and a level adjuster 13. Thereafter, an off-hook relay 2 is driven to disconnect a telephone line L. Consequently, the operator of a telephone equipment 1 is not troubled with incoming from the facsimile equipment.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a telephone device and a facsimile device, and more particularly, when the other party is a facsimile device, the bell does not ring and the facsimile device does not ring the bell. This paper relates to a telephone device that prevents this and a facsimile device that prohibits re-call processing when the other party is not a facsimile device. (Prior Art) Recently, as facsimile machines have become more widespread, various functions have been added to improve convenience, one of which is an automatic re-calling function.

A facsimile machine equipped with this automatic re-call function stores the recipient's telephone number in its memory when automatically sending a message.
When the call is not received because the other party is busy, or because the call cannot be received due to running out of recording paper, or even when the call is received but communication is not established, the telephone number of the other party is read from the memory after a predetermined period of time. automatically calls again. Therefore, when the other party is a telephone, etc., there is no need for the operator to perform the transmission operation again, and the convenience of the facsimile machine is improved. (Problem to be Solved by the Invention) However, such conventional facsimile machines are configured to perform re-call processing not only when the other party is busy, but also when communication is generally unsuccessful.
Even if the other party is not a facsimile machine but a telephone VTRI1 due to an error in inputting the telephone number, etc., the re-call process is performed as communication is not established. Therefore, if the incorrectly entered telephone number is the number of a telephone device, even if you pick up the handset of the telephone device, you will only hear silence or a dial tone, which will be repeated many times during the re-call process. Become. This kind of thing is unpleasant for the person on the telephone device side, and also gives rise to suspicion that the call is a prank call.
Furthermore, if the destination is an answering machine, the facsimile machine waits for a predetermined period of time for a signal from the receiving side, which results in the memory for recording the answering machine being wasted every time a call is made again. In particular, with facsimile machines equipped with speed dial Ia function, if an incorrectly entered telephone number is registered, the operator may check the registered name at the time of transmission, but the
I don't do much i-authentication. Therefore, incorrectly entered phone numbers may continue to be used without being corrected, causing inconvenience to the other party. (Object of the Invention) Therefore, the invention as claimed in claim 1 provides a telephone device that, when there is an incoming call, receives the call without ringing the bell, checks whether the other party is a facsimile machine, and checks if the other party is a facsimile machine. , the purpose is to prevent the bell from ringing and to prevent the user from having to make calls or re-calls from the facsimile machine. Further, in the telephone device, the telephone device further transmits a ringback tone after an incoming call, thereby preventing a silence state when the other party is a telephone device, and preventing the other party from becoming silent. The purpose is to prevent people from feeling anxious. The invention as claimed in claim 3 provides a facsimile device in which, during transmission, if the destination device transmits a concave cutting command signal without transmitting a predetermined ant identification signal after receiving a call, the facsimile device performs a re-calling process. By not doing so, it is possible to prevent unnecessary re-call processing for parties other than facsimile machines, prevent unnecessary occupation of the line, and prevent inconvenience to other parties using telephone equipment, etc. The purpose is to prevent In the facsimile apparatus, when a valid facsimile control signal is not received within a predetermined time after receiving a call at the time of transmission, re-calling processing is not performed. The purpose of this system is to prevent wasteful re-call processing for parties other than the device, thereby preventing the unnecessary occupation of the line, and to prevent causing trouble to the other party, such as a telephone device. (Structure of the Invention) In order to achieve the above object, the invention according to claim 1 includes a ringing detection means for detecting an incoming signal from a line, and a ringing suppression means for suppressing ringing of a bell. A signal detecting means for detecting a predetermined facsimile control signal from the line is provided in the telephone Vt position which rings a bell after detecting the incoming signal from the line, and after detecting the incoming signal from the line,
The invention according to claim 2 is characterized in that the ringing of the bell is made to wait for a predetermined period of time, and if the facsimile control signal is detected within this period, the bell does not ring. A ringing detection means for detecting and a circuit for connecting/disconnecting the line.
jlNJ contact means, a ringing means for ringing a bell, and a reception request detection means for detecting a reception request from an operator, and when there is ringing from the line, it rings the bell,
When a reception request is received, the telephone device that stops the ringing of the bell and connects the line includes a signal detection means that detects a predetermined facsimile control signal from the line, and sends out a facsimile iDl]in signal that indicates a line disconnection command. cutting 13
and a ringback tone sending means for sending out a ringback tone, and when there is ringing from the line, the ringback tone is sent out to the line without ringing the bell. If a predetermined facsimile system 111 signal is detected within a predetermined time, the transmission of the ringback tone is stopped and the line is disconnected after a line disconnection command signal is sent.If a predetermined facsimile control signal is not detected within a predetermined time, The invention according to claim 3 is characterized in that a bell is rung while transmitting a ringback tone, and the invention according to claim 3 transmits a facsimile by interchanging a facsimile control signal with the other party's device, and also prevents the transmission from being interrupted without completing the facsimile transmission. Sometimes, a facsimile machine that automatically performs re-call processing will perform automatic re-call processing if a line disconnection command signal is sent without a predetermined identification signal being sent after the other party receives a call. The invention according to claim 4 is characterized in that the facsimile control signal is exchanged with the other party's device to transmit the facsimile, and when the facsimile transmission is interrupted without being completed, the re-calling process is automatically performed. In a facsimile machine, a facsimile system 1 that is valid within a predetermined time after the other party receives a call
This system is characterized in that automatic re-call processing is not performed when no n signal is received. This will be explained in detail below based on examples. 1 and 2 are claims 1 and 2! 1 is a diagram showing an embodiment of the invention described in FIG. FIG. 1 is a block diagram of the telephone device 1. The telephone device 1 includes an off-hook relay (gyrodisconnection means) 2, a ringing detector (ringing detection means) 3, a transformer 4, a 2-wire 4-wire converter 5, a tone Detector 6, ringback tone transmitter (
Ringback tone sending means) 7, level regulators 8, 9
, a handset 10, a control unit 11, a modem 12, a level adjuster 13, a tone transmitter 14, a ringer ringer 15, a ringer element 16, and the like. Telephone line L is connected to off-fusoku relay 2,
The off-hook relay 2 connects and disconnects the telephone line IL according to instructions from the control unit l1, and when a call arrives, the telephone line &? i
In addition to making the L connection, the phone number is sent when making a call. The ringing detector 3 is connected to the telephone line L,
The control unit 11g detects ringing (incoming call signal) from the telephone line L and outputs a ring signal LS. Tone detector 6
is a predetermined facsimile control signal sent from the telephone line ￥aL when the other party has a facsimile machine, for example,
Detects a CNG signal (calling tone) and outputs the detection result to the control section 11. The ringback tone transmitter 7 outputs 2 lines 4&'i! according to instructions from the controller i211 section 1l. The ringback tone (e.g. 1611z
40011z modulated tone) to the telephone line L, and the ringback tone sent from the ringback tone transmitter 7 is not only sent to the telephone line &51L but also input to the tone detector 6. However, tone detector 6
It has no effect because it is removed by the bandpass filter.
The handset 1O is equipped with a speaker 17, a microphone 18, etc., the speaker 17 amplifies the received sound from the telephone line &91L, and the microphone 18 collects the operator's voice and outputs it as the transmitted sound. These received and transmitted sounds are level-adjusted by level U1 adjusters 8 and 9, respectively. The operator can have a conversation by picking up the handset 10. That is, an off-footer switch (not shown) is attached to the telephone device 1, and when the operator attaches and detaches the handset 10, the off-hook switch is turned off/on, and this off/on signal is output to the control section 11. Ru. Therefore, when the operator picks up the handset lO when requesting reception or transmission, the off-footer switch is turned on and an off/on signal is output to the control unit 11 as a signal indicating a reception request or transmission request. The off-hook switch functions as a receiving request detection means. The control unit 11 controls each part of the telephone device 1 according to a program stored in the internal memory, executes the sequence as the telephone device 1, and executes the incoming call processing of the present invention. In addition, the control unit 1
1 is a function for transmitting facsimile control signals, especially D
It has the function of transmitting a CN signal (disconnection command signal). That is, the control unit 10;! The DCN signal is output as a binary signal to the modem 12, modulated by the modem l2, and level adjusted by the level adjuster 13, and then sent to the telephone line & SL. Further, the control unit l1 drives the tone transmitter 14, and causes the tone transmitter 14 to output a tone signal, particularly a CED signal (called terminal identification signal). The ringer ringer l5 drives the ringer element l6 in accordance with the instruction (drive signal) from the controller l1 to ring the bell. Next, the operation will be explained. The characteristic of this method is that it determines whether or not it is a facsimile device, and if it determines that it is not a facsimile device, it rings a bell, and if it determines that it is a facsimile device, it does not ring the bell. The explanation will be based on the flowchart shown in .

When the telephone device 1 receives an incoming {δ signal from the telephone concave line L (if there is ringing), the ringing detector 3 detects this incoming signal and outputs a ring signal LS to the control if1 section l1. When the ring signal LS is input, the control unit 11 controls the off-hook relay 2 771 L to connect the telephone line L (
At the same time, the ringback tone transmitter 7 is driven to send a ringback tone to the telephone line. Next, it is checked whether a predetermined facsimile control signal, e.g., a CNG signal, is received within a predetermined time, e.g., 5 seconds (steps St, S3).
-During this time, the telephone line L is connected to the ringtone transmitter 7.
Since a ringback tone is sent from the other party, even if the other party is a telephone device, there will be no silence, and the impression of a pseudo-call can be given, thereby eliminating feelings of anxiety. If the facsimile control signal is not received within a predetermined time, it is determined that the other party is not a facsimile machine, and a drive signal is output to the ringer ringer 1315. When the drive signal is input, the ringer ringer l5 drives the ringer element 16 to ring the bell (step S4).
), and thereafter performs normal post-processing as the telephone device I (step SS). That is, when the handset 10 is picked up, the driving of the ringback tone transmitter 7 is stopped and conversation is enabled using the handset 10, and if the other party disconnects the line before the handset 10 is picked up, the ringback tone is sent out. At the same time, the off-hook relay 2 disconnects the telephone line L. On the other hand, when a predetermined facsimile control signal is transmitted within a predetermined time, the facsimile itill ill signal is detected by the tone detector 6, and the tone detector 6 outputs the detection result to the control section 11. When the +tlli control unit 11 receives a signal indicating that a facsimile control signal has been received from the tone detector 6, it determines that the other party is a facsimile machine, drives the tone transmitter 14, and sends out a CHD signal. DCN via modem 12 and level adjuster l3
Send a signal (step Sh). Thereafter, the off-hook relay 2 is activated to disconnect the telephone line L. Therefore, since the telephone device rI11 does not ring the bell, the telephone device 1
operators are not bothered by incoming calls from facsimile machines. The effect is especially noticeable at night. Furthermore, the destination facsimile machine determines that the facsimile transmission procedure has been completed and does not perform re-call processing. As a result, the operator of the telephone device 1 can be prevented from having to be troubled by repeated calls from the other party's facsimile device. Furthermore, when the telephone device l is an answering machine, it is possible to prevent the memory for storing the answering machine from being wasted by the process of re-calling from the facsimile machine.

In addition, in this embodiment, since the CED signal is output before outputting the DCN signal, the facsimile machine is configured to proceed to the subsequent facsimile procedure only after receiving the CED signal. Also, the DCN signal can be effectively applied to the other party's facsimile machine, and re-calling processing by the other party's facsimile machine can be reliably prevented.

Additionally, the facsimile control signal initially sent from the facsimile machine may not necessarily be a CNG signal,
The tone detector 6 can also be set to be compatible with signals other than these CNG signals. Further, although the above embodiment has been described with respect to a telephone device alone, the present invention is not limited to this, and can be applied to a telephone device attached to a facsimile device, for example. In this case, the tone detector 6
The facsimile machine can be used as the tone transmitter 14 and the like. Furthermore, in this case, the above-mentioned incoming call processing is executed only when the facsimile machine to which the telephone device is attached does not receive facsimile.

In addition, in the above embodiment, D
Although the CN signal is sent, it is not limited to this.
The facsimile control signal (CNG (
t), the line may be disconnected without sending the DCN signal. In this case, D C N {
The tone transmitter l4 for sending number i is no longer necessary, and the telephone device l
It is possible to simplify the process and reduce the cost. Furthermore, in the embodiment described above, when a facsimile control signal fδ is received within a predetermined time, the line is disconnected, but the present invention is not limited to this, and the bell may simply not ring. In this case, the telephone device 1, which is not bothered by calls from the facsimile device, can be made even more economical and inexpensive. 3 to 5 are diagrams showing an embodiment of the invention according to claim 3 and claim 4.

A telephone line L is connected to the off-fuku relay 22 and the polarity reversal detector 23, and the off-fuku relay 22 and the polarity reversal detector 23 are constructed as shown in FIG. That is, the offline relay 22 operates according to instructions from the system control unit 30 to connect and connect the telephone line L.
In addition to disconnecting the connection, the phone number is also dialed. The polarity reversal detector 23 includes 2 & II photocouplers P connected in parallel.
It is equipped with CI, PC2 and varistor VR, and the photo coupler PCI and photo coupler PC2 are used to connect the phone
&'Detect the reversal of the polarity of the current flowing through jlL. The polarity reversal detector 23 outputs the detection result to the system control unit 30 via the I/O port 28. The varistor VR of the polarity reversal detector 23 is used to protect the photocoupler Pct and PC2. The level adjuster 26 adjusts the level of the signal sent from the modem 27 to the telephone line L, and the modem 27 modulates the transmitted signal and restores the received signal. RAM29
Various information necessary for the control 11 of the facsimile machine 121 is stored in the field, and when transmitting, the telephone number of the other party, etc. is stored. The system control unit 30 controls each part of the facsimile machine 21 according to a program stored in an internal memory or the like to execute the sequence of the facsimile machine 21, and also executes the re-calling process of the present invention. For example, a thermal recording device is used as the block 3l, and the block 3l records on the thermal recording paper directly or indirectly via an ink sheet.
As the scanner 32, for example, CO D (Charg
An image scanner using an e-Coupled Device is used to read the image of a document and output it as image data. The operation section 33 includes various operation keys, a liquid crystal display, etc., and performs communication between the operator and the facsimile machine 121. In addition, in Fig. 3, 34 is a system bus. Next, the effect will be explained.

The present invention is characterized in that when a transmission fails during transmission, it is determined whether or not the other party is a facsimile machine based on the way the other party responds, and it is determined whether or not to perform re-call processing. This re-calling process will be explained below based on the flowchart shown in FIG. In the facsimile machine 2l, at the time of transmission, the operator inserts a document into the scanner 32, inputs transmission information such as the recipient's telephone number from the scratching section 33, and presses the start button on the operation section 33. When the facsimile machine 2l receives the transmission information, it temporarily stores the transmission information, especially the telephone number of the other party, in the RAM 29, and then! The dial pulse (
Send the telephone number) to the telephone line & IL (Step P1)
．． When the facsimile device 2l sends out a telephone number, it determines whether there is a polarity reversal within a predetermined time (time according to the recommendation of the International Telegraph and Telephone Consultative Committee (CCITT), T.30).
That is, it is checked whether the other party has gone off-hook (steps P2, P,), and if the polarity is not reversed within a predetermined period of time, it is determined that the other party is unable to receive the call due to an occurrence of recording paper out, recording paper jam, etc., and re-call processing is performed. Transition. The re-calling process is carried out by reading out the telephone number of the other party recorded in the RAM 29 after a preset waiting time, and controlling the offline relay 22 to send out a dial pulse. This re-calling process is continued until the other party goes off within the predetermined time or until a preset number of re-calls is performed (steps P, ~P4).
If the other party does not disconnect even after performing the calling process a predetermined number of times, an error report is output according to the normal procedure and the process ends (step ps). On the other hand, if the other party goes off and the polarity is reversed, then the specified time (CCITT recommendation, T.
30), or received a predetermined facsimile control signal during normal facsimile reception, such as a Dis signal (digital identification signal, etc.) or a DCN signal (line disconnection command signal), etc. ,
Check (step p, , P. , P1, P9>,
If a busy tone is received within a predetermined time, it is determined that the other party is not a facsimile machine and has refused reception, and an error report is output (step Pi*).
In this case, no re-call processing is performed. Therefore, if the other party is a telephone device, etc., it is possible to prevent re-call processing, prevent the line from being monopolized by unnecessary re-calls, and prevent the operator of the other party's telephone device, etc. It is possible to prevent the feeling of pleasure or annoyance. Also, if a predetermined period of time has passed without any response, it will be determined that the other party is not compatible or that the other party is using an answering machine, etc., and an error report will be output. Therefore, it is possible to prevent the line from being occupied by unnecessary re-call processing, and also to prevent the other party's device from performing unnecessary call receiving operations and from wasting the memory of the answering machine. Furthermore, if the DIS signal is received within a predetermined time, the other party determines that it is a compatible facsimile machine and performs normal reception processing (step P+t). When the DCN signal is received, it is determined that the other party has intentionally refused to receive the facsimile, and an error report is output (step P, ), and no re-call processing is performed.Therefore, this causes trouble to the other party who has refused to receive the facsimile. In particular, when the other party is a telephone device according to claims 1 and 2, it is possible to prevent the operator of the other party from using the telephone device to perform the re-calling process. It is possible to prevent the trouble and discomfort caused by the error report.The reason for the communication failure may be described in the error report to alert the operator of the facsimile machine 21. (Effect) Claims According to the invention described in 1, in the telephone device, the bell does not ring in response to an incoming call from a facsimile device, so that the bell does not ring in response to a call from the facsimile device or an automatic re-call. , it is possible to prevent the trouble of making and re-calling from a facsimile machine.The effect is particularly noticeable at night.The invention as claimed in claim 2 provides a telephone device that can call the other party after receiving a call. Since a ringback tone is sent until it is determined whether or not the other party is a facsimile device and necessary processing such as preventing re-calling is performed, it is possible to prevent silence when the other party is a telephone device. In addition to being able to prevent the other party from being bothered by incoming calls from the facsimile machine, it is also possible to prevent the other party from feeling uneasy. , when a line disconnection command signal is sent from the other party under certain conditions, re-call processing is not performed, so unnecessary re-call processing is not performed for destinations other than facsimile machines. It can be prevented.
As a result, it is possible to prevent unnecessary line occupancy and also to prevent bothering the other party using a telephone device or the like. According to the invention of claim 4, in a facsimile device, when a valid facsimile control signal is not received within a predetermined time after the other party's device receives a call during transmission, it is possible to prevent the re-calling process from being performed. Therefore, it is possible to prevent unnecessary re-call processing from being performed to destinations other than facsimile machines. As a result, it is possible to prevent unnecessary line occupancy and also to prevent bothering the other party using a telephone device or the like.
