Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automatic dialing device having means for storing a subscriber number and repeatedly dialing the subscriber number until the other party answers.

[Conventional technology]

Conventionally, this type of device has a plurality of subscriber numbers stored in its internal control circuit, from which an operator selects a specific subscriber number using a push button switch or the like. The selected subscriber number is then dialed repeatedly by a repeat calling circuit, a control circuit, a dialing circuit, etc. until the other party answers.

[Problems to be solved by the invention] With the above-mentioned conventional device, if a call is received from a third party after the dial is made and before the line is released and dialed again, or if the call is answered by going off-hook, In some cases, it will remain in redial mode, so
There was a problem in that even if the call was answered and the call was busy, the dialing operation was repeated. If this problem were to be solved, the operator would have to repeatedly reset the outgoing call each time an incoming call was received, which would impose unnecessary labor on the operator.

[Means for solving problems]

In order to solve the above problems, the present invention provides a detection means for detecting an incoming call or an off-hook when the line is open during repeated dialing, and a detection means for detecting the incoming call or an off-hook. The system is equipped with a means for temporarily stopping dialing when a call is made.

That is, in the present invention, dialing is repeatedly performed automatically, and if a call is received from a third party after dialing and before dialing again, dialing is temporarily stopped without manual operation.
This makes it possible to automatically dial again after a call ends.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic dialing device according to the present invention. Here, a general telephone 2 is connected to a line 3 via an automatic dialing device 1 according to this embodiment.

This line 3 is connected to the detection circuit 5 or the dial transmission circuit 1 through the contact piece A and the contact piece B of the switch 4, respectively.
Switched to 0. The detection circuit 5 detects off-hook and on-hook of the telephone 2 and an incoming call signal. The control circuit 6 has a built-in memory in which, for example, 16 subscriber numbers are stored, and also sends operation commands to each circuit to be described later. This control circuit 6 is connected to a group of push button switches 7 and a repeat transmission circuit 8. The push button switch group 7 includes a start button for starting the main body of the automatic dialing device 1, a selection button for selecting a subscriber number and inputting it to the control circuit 6, and the like. Repeat oscillation circuit 8
converts the subscriber number sent from the control circuit 6 into impulses and repeatedly sends them out. Further, a reset signal from a reset circuit 9 operated by a signal from the detection circuit 5 is inputted to the repeat oscillation circuit 8. Further, when the detection circuit 5 detects an off-hook or incoming signal, this detection signal is applied to the control circuit 6 and the reset circuit 9.

The dial impulse of the control circuit 6 is guided to the dial transmission circuit 10. Dial transmission circuit 10
is a relay circuit, which is connected to the line 3 via the contact B of the switch 4, and drives the relay by dial impulses sent from the control circuit 6 to send a dial signal to the line 3. Further, the signal from the line 3 is input to the amplifier circuit 11 via the contact B of the switch 4 and the dial transmission circuit 10. The output of this amplifier circuit 11 is connected to a speaker 12, which converts the dial tone from the station into sound. Further, a display 13 is connected to the control circuit 6 to inform the user that dialing will be made again after the dialing is completed.

Next, the operation of the automatic dialing device according to this embodiment configured as described above will be explained.

While the telephone 2 is on-hook, the operator presses the activation button of the push button switch group 7. In response to this, the control circuit 6 activates the main body of the automatic dialing device 1. At this time, the switch 4 normally connected to the contact piece A side is switched to the contact piece B side by a control signal from the control circuit 6.
connected to. As a result, line 3 is closed and a dial tone is sent from the station. This dial tone can be heard by the operator via the speaker 12 via the dial transmission circuit 10 and the amplifier circuit.

Next, the operator selects the subscriber number displayed on the push button switch group 7 and presses the selection button. By this operation, the control circuit 6 sends out the corresponding subscriber number from its memory as a dial impulse, and the repeat transmission circuit 8 turns this dial impulse into a repeat dial impulse and sends it out to the dial transmission circuit 10. The dial transmission circuit 10 receives this repeated dial impulse and sends a dial signal to the line 3 via the contact B of the switch 4.

Here, the characteristic operation of this embodiment will be explained.

By giving an instruction to the control circuit 6, the repeat calling circuit 8 calls the other party for a certain period of time after sending the first dial impulse, and then opens the line 3 by switching the switch 4 to contact A for a certain period of time. . Thereafter, the switch 4 is switched to contact B to close the line 3 again and send out the dial impulse again. Repeat oscillation circuit 8
causes the control circuit 6 to repeat such operations. Now, when there is an incoming call from a third party while the line 3 is open, the detection circuit 5 detects this incoming call signal, operates the reset circuit 9, and temporarily stops the automatic dialing operation of the repeat calling circuit 8. line 3
When the telephone responds to an incoming call from a third party during the open period and goes on-hook after the call ends, the detection circuit 5 detects this on-hook and transmits it to the control circuit 6. Then, the control circuit 6 switches the switch 4 to the contact B again to close the line 3. In addition, due to the on-hook, the repeat oscillation circuit 8 is reset via the reset circuit 9.
The instruction to temporarily stop the repeat dialing operation is released, and the output from the repeat calling circuit 8 causes the control circuit 6 to send the subscriber number in the memory as a dial impulse to the dialing circuit 10. As a result, the dial transmission circuit 10 sends a dial signal to the line via the switch 4. Then, the display 13 notifies the operator that dialing will be made again after the dialing is completed.

[Effect of idea]

As explained above, the present invention repeatedly closes and opens the line and repeats the dialing operation, and also dials when it detects an incoming call from a third party or the off-hook of the telephone when the line is opened. The outgoing call operation is temporarily stopped, and when the phone is detected to be on-hook, the repeat dialing operation is started again.This makes it possible to repeat and automatically make a dial out call. If there is an incoming call, it will automatically pause the outgoing call, and after the call with the third party ends, it will be able to return to the outgoing call again.
As a result, the labor of the telephone operator can be significantly reduced, and the functions of the telephone device can be significantly improved.
