Description

[Detailed Description of the Invention] [Technical Field] The present invention provides an inter-terminal system for selectively connecting a telephone and multiple types of terminal devices. ) This is an inspiration for improving equipment.

[Prior art]

Conventionally, communication methods have been widespread in which telephones and various terminal devices are connected to a telephone line serving as a public communication line.For example, when a facsimile machine is connected as a terminal device, it is difficult to make a call. On the other hand, after the phone rings several times, the line is switched to the facsimile machine, causing the inconvenience that the calling party cannot connect to the other party's phone and hears the automatic answering tone, which is unpleasant. On the other hand, as long as the facsimile machine is set to the automatic incoming call mode, the called party cannot receive the incoming call even though the telephone bell rings. The present inventor has proposed a terminal control device to solve this problem in Japanese Patent Application No. 62-35397, etc., and this device is capable of controlling the telephone when a call is received from the telephone. In response to a call from a terminal device, the line is automatically switched so that the call can be received at the terminal device. The present inventor has proposed that in this terminal control device, it is possible to reliably switch and connect lines by giving a specific frequency signal to multiple types of terminal devices and automatically transmitting this frequency signal to the receiving side. We have discovered that this is possible and have come up with the present invention.

(Objective) An object of the present invention is to provide an improved terminal control 2N device that can reliably switch and connect a telephone and a plurality of types of terminal devices.

〔composition〕

The present invention provides a terminal control device for selectively connecting a telephone and multiple types of terminal devices, which is provided with a signal sending means that automatically sends a predetermined frequency signal that differs depending on each terminal device from the transmitting side to the receiving side after line connection. It is.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First, to explain the overall configuration diagram in Figure 1, l
2 is a telephone, and 2 is a computer as a terminal device. This computer 2 is equipped with a modem and is capable of personal computer communication. 3 is a facsimile device also serving as a terminal device, and 4 is a terminal control device main body.In this example, a control circuit component 5 and a signal transmission switching portion 6 are formed separately. The control circuit component 5 is provided with three pushbutton switches 7.8.9, which may be integrated, and these pushbutton switches 7.8.9 can be switched on or off at home by the user's switch design. The mode selection function at J1 is said to be switchable. IO is a cover member that can be opened and closed.
When the cover member 10 is opened, a microphone and switches (not shown) for an IC recording means for recording telephone response messages are provided inside the cover member 10. The signal transmission switching section 6 has a signal transmission means for automatically transmitting a specific frequency signal given to the computer 2 and the facsimile machine 3 to the receiving side, and the oscillation 2S as this signal transmission means. (not shown), Takagun (1209
1hi, 13361 degrees, 1477+1z, 4633)hi)
, Low group (6971, 7201, 852) Hi, 941
A single-frequency signal is oscillated from each of the two groups (1 and 2), thereby obtaining a two-frequency signal and transmitting it to the receiving side.

In this example, when the slide switch 11 is slid from the neutral position to the A side shown in the figure, the frequency signals for the computer 2, that is, the frequencies of the high group 14771 and the low group 6971, are transferred to the B side shown in the figure. When the slide is made, the frequency signals for the facsimile machine 3, that is, the high group 1477+1z and the low group 72 old frequencies are combined, and this signal is an intermittent signal that repeats a 40 ms transmission and a pause a predetermined number of times. It is sent to the receiving side as . Reference numerals 12 and 13 are visual display lamps provided in the signal transmission switching unit 6 to blink and display the operating procedure of the apparatus, and are particularly useful for hearing-impaired persons.

14 is the telephone line, 15.16.17.1B is the telephone ah computer 2, facsimile machine? j3 and the terminal control device main body 4.

Next, the control circuit component 5 will be explained with reference to FIG. 2. Reference numerals 19, 20, and 21 are relay contacts for switchingly connecting the telephone 1, the computer 2, and the facsimile device 3 to the telephone line 14, and 22 is a telephone Incoming call from line 14 (
1G1[z); 23 is a frequency signal detection means for detecting a frequency signal sent out by the signal sending means provided in the signal sending switching unit 6 on the sending side; 25 is a loop detection means for detecting a response when the telephone 41111 responds, and 26 is a means for transmitting a prerecorded response message from the receiving side to the transmitting side. 27 is a recording means for recording the message sent from the sending side; 28 is a telephone receiving means for inputting the outputs of the incoming call detection means 22, the frequency signal detection means 23, and the loop detection means 25; Call line 14
, the computer 2 and the facsimile machine 3, and 29 is a ringing means for ringing a bell (tone ringer) to prompt the telephone 411 to respond.

Subsequently, the operation of this embodiment will be explained.

First, when performing facsimile transmission using the facsimile device 3 on the sending side, the user
After sliding the slide switch 11 to position it on the side B in the figure, the facsimile machine 3 is started. On the other hand, when the push button switch 7 of the control circuit component 5 is pressed on the receiving side and the first mode selection function, that is, the home mode is set, a call is received from the sending side via the telephone line 14. (1611z) is detected by the combined call detection means 22, and its output is applied to the control means 2 to form a DC loop and establish a line connection. That is, the ringing means 29 is driven by the control means 2 and 8 to ring the bell for a predetermined period of time (appropriate number of times) in order to prompt the telephone l to respond, and if the recipient takes the handset off-hook during this period, the loop detection means 25 detects this. The output is applied to the control means 28. The control means 28 issues a command signal based on the detection output of the loop detection means 25, and the relay contact 19 is actuated to switch the contact. In this state, 1/17711z and 720+1 are generated from the oscillator of the signal transmission section 0 section 6 on the transmitting side.
Since the 2Ial wave signal of z is sent out, this is 1j
The frequency signal is detected by the frequency signal detection means 23, and its output is applied to the control means 28. When the receiver listens to this frequency signal and puts the handset on the hook, the relay contact 20.21 is activated based on the command from the tljJ 28 means 28. When activated, the contacts are switched, and the facsimile machine 3 is activated and a known protocol is executed to receive the facsimile.If the sending side is a manual facsimile machine, a message to this effect is sent to the receiving side. When the recipient repeatedly presses (turns) the appropriate number on the button (dial) on the telephone L, the relay contacts 20 and 21 operate in the same way as above, switching the contacts, and transmitting the facsimile machine. 3 is activated.

Next, if the pushbutton switch 8 is pressed repeatedly to set the second mode selection function, that is, the automatic mode, the line is connected in the same way as above, and then the iJ is called by a command from the key means 28. The sound sending means 24 is activated and sends the telephone ringing tone back to the sending side for a predetermined period of time. During this time, the frequency signal detection means 23 detects whether or not a frequency signal is being sent, but during this time, the telephone 1 is in a non-ringing state.

During this time, when a two-frequency signal for the facsimile machine 3 is sent out, it is detected by the frequency signal detection means 23 and its output is applied to the In means 28. Sound sending means 24
operation is stopped, and the relay contacts 20 and 21 are activated to switch the contacts, and the facsimile machine 3 is activated to receive a facsimile. On the other hand, when the two-frequency signal is not transmitted within a predetermined time, the control means 2
The ringer 29 is driven by the command 8 to ring the bell for prompting the telephone 6 to answer. Then, if there is a response from the telephone al, a conversation is established between the sending side and the receiving side, as in the case of the first mode selection means. At this time, if there is no response from the telephone 1 even after the bell rings for a predetermined period of time (appropriate number of times), the voice response signal sending means 26 is activated by a command from the control means 28, and a prerecorded response message is sent to the sending side. It is sent out. In addition,
In this case, when the sending side is a manual facsimile machine, after the transmission of the L response message is completed, the relay contacts 20 and 21 are activated by a command from the control means 2B, and the line 14 is switched to the facsimile machine 3 side, so that facsimile reception is performed. It has become. After sending this response message, the second mode selection function is automatically changed to the third mode selection function, which will be described later.

Next, the pushbutton switch 9 is repeatedly pressed, and if the third mode selection function, that is, the absence mode is set, the relay contact 20 is activated when the sending side is a facsimile machine;
21 is activated, the line 14 is switched to the facsimile machine 3 side, and facsimile reception is performed, as in the case of the second mode selection function. And at this time phone a
The bell of ll rings for a predetermined period of time or remains silent.

Then, after a predetermined period of time has elapsed, the voice response signal sending means 26 is activated by a command from the control means 28 to send a response message to the sender, and the recording means 27 is activated to record the message from the sender. It has become.

When the series of message transmission and reception is completed in the manner described above, the relay contacts 19, 20, and 21 each return to their original positions and prepare for the next new call.

In the above embodiment, the operating state was explained only when the sending side is a facsimile machine, but since the same applies to a computer, the explanation thereof will be omitted.

The present invention is not limited to the above-mentioned embodiment, and can be implemented in various ways. In this case, once the handset of telephone 1 is off-hook, the setting is automatically changed to the first or second mode selection function, or if the first mode selection function is set, If the line is disconnected even if the bell rings for a predetermined period of time (appropriate number of times), there is no response from the telephone [1], the setting is changed to the third mode selection function, and after a predetermined period of time, the mode selection of section 1 is selected again. Various mode selection functions can be combined depending on the user's situation, such as enabling return to function.
