(Structure) The present invention is a device that detects a calling signal sent from a calling party via a telephone line and switches and connects the line to a telephone or terminal device, and the device selects a mode of presence or absence. It is equipped with a switchable operating means, and is configured to automatically switch to the absent mode when there is no response from the telephone and the line is disconnected when the present mode is set.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

First, to explain the overall configuration shown in FIG. 1, numeral 1 in the figure is a terminal call control device, and 3
Two pushbutton switches 2.3.4 are provided;
These switches 2, 3, and 4 constitute operating means that have a mode selection function when the user is at home, at work, or away, by operating the switches as will be described later. In addition, in this book, the time at home and the time at the office are referred to as the present mode, and the time when the person is away is referred to as the absent mode. 5 is also the terminal call control bag H
a cover member provided at the lower part of the t, which can be opened and closed;
When the cover member 5 is opened, a push button switch (not shown) for recording means is provided inside the cover member 5 for recording a telephone response message. 6 is a telephone, 7 is a terminal device, and 8.9 is a connection cord for connecting the telephone 6 and terminal device 7 to the terminal call control device 1. Although only one facsimile machine is shown as the terminal device 7 in the illustrated example, various terminal devices such as a telemeter device, a personal computer communication device, and a home security device can be connected.

Next, the configuration of the control circuit section of the terminal call control device 1 will be explained with reference to FIG. 2. L+ and Lz are telephone lines, and the lines L1 and L2 have relay contacts IO and 1.
A telephone 6 is connected through the relay contact 11, and a facsimile device 7 is connected to the meter contact side of the relay contact 11. 12 is an incoming call from telephone line L1, L2 (16
13 is a facsimile ringing signal (1100Hz CNG) sent from the calling side.
14 is a ring tone sending means for sending a telephone ring tone to the calling party; 15 is for detecting a response when the telephone 6 responds; 16 is a voice response signal transmitting means for transmitting a prerecorded response message from the called side to the calling side, and this voice response signal transmitting means 16 is a voice synthesis IC in this embodiment. However, other recording means such as a tape recorder may also be used. Reference numeral 17 mainly comprises a recording means such as a tape recorder for recording a message from the calling side, and 18 mainly comprises a microprocessor (CPU), which includes the incoming call detection means 12, the ringing signal detection means 13, and the loop detection means 1.
5 to the telephone line L1 and L2 as input to the telephone 6.
Alternatively, a control means 19 performs various controls such as switching connection to the terminal device 7, and 19 is controlled by the output of the control means 18, and is a ringer that rings a bell (audible sound such as a tone ringer) to prompt the telephone 6 to respond. It is a means.

Next, the operation of this example will be explained.

First, when the pushbutton switch 2 of the terminal call control device 1 is pressed and the first mode selection function, that is, the current mode is set, when there is an incoming call from the telephone line L2, this is activated. The incoming call is detected by the incoming call detection means 12, and its output is applied to the control means 18 to form a DC loop, and the control means 18 drives the ringing means 19 to ring the bell to prompt the telephone a6 to respond. In this way, the bell rings for a predetermined period of time (appropriate number of times), and if the called party takes the handset of the telephone 6 off-hook during this period, this is detected by the loop detection means 15 and its output is applied to the control means 18. The control means 18 issues a command signal based on the detection output of the loop detection means 15, and the relay contact 10 is activated to switch the contact to the telephone 6 side, so that if the calling party is on a telephone call, communication with the called party is interrupted. A conversation will take place.

On the other hand, if the calling party is a facsimile device, a facsimile ringing signal is sent out, so this ringing signal is detected by the ringing signal detection means 13, and its output is sent to the control means 18.
When the called party hears this ringing signal and puts the handset on the hook, the relay contact 11 is actuated based on a command from the control means 18 to switch the contact to the facsimile machine 7 side, and the facsimile machine 7 It will be activated. After that, the called identification signal (2100
HzCED signal) to the calling party, a known protocol based on CCITT recommendations is executed, and the message is received. If the calling party is using a manual facsimile machine, a message to this effect will be sent to the called party, so the called party can press (or dial) the appropriate number on the button (dial) on telephone A6. operation), the relay contact 11 operates in the same way as above and switches the contact,
The facsimile machine 7 is now activated. If this mode is set and 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 6 and the line is disconnected, the second mode selection function or the third mode selection described later is activated. The settings are automatically changed to prepare for the next call.

Next, when the pushbutton switch 3 is repeatedly pressed and the second mode selection function, that is, the presence/absence combination mode is set, a DC loop is formed in the same way as above, and then the control means 18 is activated. The ringing tone sending means 14 is driven by the command and returns the telephone ringing tone to the calling party. If the calling party is a facsimile machine, a facsimile ringing signal is sent, so this ringing signal is sent to the ringing signal detection means 1.
3 and its output is applied to the control means 18.

In this way, the presence or absence of a facsimile ringing signal is detected within a predetermined period of time, during which time the telephone 6 is in a non-ringing state. Then, based on a command from the control means 18, the operation of the ringing tone sending means 14 is stopped, and the relay contacts 10 and 11 are further activated to switch the contacts, and the facsimile machine 7 is started, and from then on, the operation in the above-mentioned mode is started. The message is received in the same way as in the case of . On the other hand, when a facsimile calling signal is sent within the predetermined time and is not detected by the calling signal detecting means 13, the ringing means 19 is driven by a command from the control means 18 to prompt the telephone 6 to respond. ring the bell. If there is a response from the telephone 6, a conversation between the calling party and the called party will take place in the same manner as in the above-mentioned busy mode. In this case, if there is no response from the telephone 6 even after the bell rings for a predetermined period of time (appropriate number of times), the voice response signal sending means 16 is activated by a command from the control means 18 to inform the user that the user is away as recorded in advance, etc. A response message is sent to the calling party. In this case, if the calling party is a manual facsimile machine, after the sending of the response message is finished, the relay contact 11 is activated by a command from the control means 18, and the lines L+ and Lz are switched to the facsimile machine W7,
Messages are now being received.

Now, when the pushbutton switch 4 of the terminal call control bag W1 is pressed and the third mode selection function, that is, the absent mode is set, the relay contacts IO and 11 are activated when the calling party is a facsimile machine. The line L is switched to the facsimile machine 7 and the message is received in the same manner as in the above-mentioned cloth/absence mode. At this time, the bell of the telephone 6 either 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 16 is activated based on a command from the control means 18 to send a response message to the calling party, and the recording means 17 is activated to record the message from the calling party. This is what we are meant to do.

When the series of message transmission and reception is completed in the manner described above, the relay contacts 10 and 11 each return to their original positions and prepare for the next new call.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but can adopt various embodiments. For example, the above embodiment has three mode selection functions, but this can be changed to two mode selection functions. In other words, it is possible to have only the presence/absence mode, and if the terminal equipment is a personal computer communication device, it is possible to use 1800HzC as a calling signal.
Since a 3T signal or the like is sent out, this may be detected by the calling signal detection means.

〔effect〕

As described in detail above, according to the terminal calling device according to the present invention, the user can always send an optimal message to the calling party according to the situation by means of an operation means that can select and switch between present and absent modes. This has the great effect of making it possible to send and receive data and to make more effective use of various terminal devices.
