Abstract

PURPOSE:To add an automatic dialing function to a key telephone set without an automatic dialing function by executing acoustic coupling to the handset of the key telephone set to originate a multifrequency dialing signal, and reproducing the multifrequency dialing signal of the objective telephone number with a program searching selecting switch. CONSTITUTION:A receiver 32 is mounted on a handset pedestal, a microphone 11 by the operation of a function selecting switch 13 is allowed to stuck to the receiver 32, the microphone 11 is acoustically coupled with the receiver 32, and the microphone 11 is operated as a sound collector. Thereafter, the function selecting switch 13 is made into a condition shown as a broken line in a figure, and a memory part 22 is made into a sound recording starting condition by the control of a control part 21. When the PB signals of the plural telephone numbers are recorded on a single sound recording tape in the memory part 22, by using the program searching function, only the PB signal sound of the desired telephone number can be reproduced. Thus, the automatic dialing function can be added to the key telephone set without the automatic dialing function.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic dialing device.

[Conventional technology]

Conventionally, the automatic dialing function of push-button telephones stores a telephone number in a storage device built into the push-button telephone, and when making a call, when a designated selection button is pressed, the specified telephone number is read from the storage device and converted into a dial signal. It is configured to convert and transmit.

[Problem to be solved by the invention]

The automatic dialing function of the conventional push-button telephone described above stores a telephone number in the storage device built into the push-button telephone, and when making a call, by pressing a designated selection button, the designated telephone number is retrieved from the storage device. Since it is configured to convert into a read dial signal and make a call, if a telephone subscriber who has a push-button telephone without an automatic dialing function desires an automatic dialing function, the push-button telephone itself can be converted to an automatic dialing function. The disadvantage is that the telephone must be replaced with a push-button telephone.

[Means to solve the problem]

The automatic dialing device of the present invention includes a speaker unit that can be acoustically coupled to a transmitter of a push-button telephone that transmits a multi-frequency dial signal and transmits a reproduced multi-frequency dial signal; a microphone unit that can be acoustically coupled to a receiver of a telephone and collects a plurality of multi-frequency dial signals in time series; a changeover switch that switches signals between the speaker unit and the microphone unit; and a switch connected to the changeover switch. and a recording/playback device for recording the plurality of multifrequency dial signals and reproducing the multifrequency dial signal selected by a cue selection switch from among the plurality of recorded multifrequency dial signals.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

- In FIG. 1, the automatic dialing device 1 of this embodiment is acoustically coupled to a transmitter 31 of a push-button telephone 3 having a multi-frequency dial signal (hereinafter referred to as PB double signal) transmitter (not shown). a speaker 12 that is connected to the speaker 12, a microphone 11 that is acoustically coupled to the handset 32 of the push-button telephone 3, and a function that switches between an input signal to the speaker 12 and an output signal from the microphone 11 to start recording, end recording, and playback. a selection switch 13; a storage unit 22 for recording and storing a plurality of PB double signals corresponding to a plurality of telephone numbers;
One PB from a plurality of PB multiplied signals stored in the storage unit 22
It includes a cue selection switch 23 for selecting a double signal, a lamp 24 indicating the end of PB double signal reproduction, and a control section 21 for controlling recording and playback of the storage section 22.

Next, the operation of this embodiment will be explained.

First, the operation of recording a PB signal tone of a telephone number will be explained.

When recording the PB signal tone of a telephone number in the storage section 22, a recording tape is loaded into the storage section 22, and the recording tape is advanced to the end point of the PB signal tone of the last telephone number currently recorded. Then, the handset 32 is placed on the handset receiver and the microphone 11 is brought into close contact with the handset 32 by operating the function selection switch 13 to acoustically couple the microphone 1 and the handset 32, and the microphone 11 is operated as a sound collector. Do it like this. Then function selection switch 1
3 is brought into the state shown by the broken line, and the storage section 22 is brought into the recording start state under the control of the control section 21.

Next, when the user presses the push button 33 on the push-button telephone 3 to input the number of the party to be recorded, a PB signal tone is heard from the receiver 32. This PB signal sound is recorded into the storage section 22 through the microphone 11 and the control section 22. Next, by operating the function selection switch 13 again, the microphone 11 that was operating as a sound collector is immediately turned off, and a preset length of silence required by the cueing function during playback is placed behind the PB signal tone. to record, and then stop recording.

In this way, one recording tape contains multiple telephone number PBs separated by silence of the length necessary for cueing.
A signal tone is recorded.

Next, a function for reproducing a PB multiplied signal of a telephone number will be explained.

If multiple telephone numbers are recorded on one recording tape in the PB double signal storage unit 22, by using the cue function, only the PB signal tone of the desired telephone number can be played back. . The operation for cueing involves first selecting the playback function by operating the function selection switch 13 to bring it to the state shown by the solid line, and then selecting the PB of the telephone number recorded from the cueing selection switch 23. It consists of specifying whether a signal tone is desired by pressing a number button (not shown). When the cue selection is completed, the transmitter 31 is placed on the handset receiver and the speaker 12 is brought into close contact with the speaker 12 to acoustically couple the speaker 12 and the speaker 12 to operate as a loudspeaker. After this, the control unit 21
P of the telephone number reproduced from the storage unit 22 under the control of
The B signal tone is sent to the mouthpiece of the transmitter 31 through the speaker 12, and is sent to the central office via the telephone line connected to the push-button telephone 3, and the exchange operation to the other party is started.

When the control unit 21 detects a preset period of silence after playing the PB signal tone of the telephone number, it stops using the speaker 12 coupled to the handset 31 as a loudspeaker and indicates that the dialing is complete. The lamp 24 is turned on.

The caller confirms that the lamp 24 is lit and then presses the receiver 31.
The transmitter 31 is connected to the microphone 11. When it is removed from the speaker 12, the control unit 21 detects it and the lamp 24 turns off.
The caller can begin a normal call.

〔Effect of the invention〕

As explained above, the present invention is acoustically coupled to the handset of a push-button telephone that transmits a multi-frequency dial signal, so that the multi-frequency dial signal can be received and stored for recording and playback. By making it possible to reproduce the multi-frequency dialing signal of the target telephone number using the cue selection switch, there is an effect that an automatic dialing function can be provided to a push-button type telephone that does not have an automatic dialing function.
