Abstract

PURPOSE:To call a terminating subscriber automatically only by the off-hook of a transmitter/receiver, by storing specific terminating telephone numbers in a telephone set. CONSTITUTION:When the transmitter/receiver of the telephone set is off-hooked and a required switch out of a selecting switch group 13 set up in the telephone set is depressed, a reading gate in a memory IC29 is opened by a signal from a hook switch state monitoring output terminal 28 and a previously stored telephone numbers are called from a dial selecting IC30. Th telephone numbers are sucessively outputted from the memory IC29 to a dial pulse generating IC33 synchronously with the speed of a reference clock pulse generating part 32. Consequently, the IC33 switches a relay driving transistor (TR) 34 and disconnects a dial pulse generating relay coil 35 to send a dial pulse.

Description

[Detailed description of the invention] The present invention relates to an automatic calling telephone.

Conventionally known butshuphone telephones are called abbreviated dials, and by simply dialing *OO three times, for example, a memory device in the telephone office is activated and the desired telephone number can be called.

In other words, the telephone number of the called party is 04.22-49-5.
In the case of 101, it was not possible to call unless the dial was rotated 10 degrees, but in the case of speed dialing, it was possible to call only by dialing *00 three times. However, this is still a hassle, so in the present invention, we have developed a telephone that allows you to call the other party by simply lifting the transceiver.

For example, there are many phone calls between the head office sales department and the factory production department, but it is troublesome to dial and call the other party each time, so it is preferable to call the other party using the speed dial. However, due to the desire to omit the time required for three dials and the switching of the mind caused by dialing even if it is a speed dial, I sometimes forget important requirements, so I do not dial at all. Things that can be called are brought into close focus.

In other words, calling the A/R side without dialing at all is not only for the purpose of saving time, but also has immeasurable various secondary effects.The present invention has technical means that do not exist at all in the past. Moreover, the idea of the present invention itself is novel.

The present invention provides (1) a storage device for a specific called telephone number in the telephone, and the storage device is activated when the handset of the telephone is lifted to automatically call the telephone number; a ringing type telephone; and (2) a direct current loop circuit formed by lifting the handset is provided in the telephone, and a hook-up detection circuit and a dial pulse generation relay contact are provided within the direct current loop circuit. , a storage device and a dial pulse generation section are connected to the hookup detection circuit, and the storage device and the dial pulse generation section are connected to the hookup detection circuit, and the storage device and the dial pulse generation section are connected to the hookup detection circuit. The gist of this invention is the configuration of an automatic ringing telephone set that automatically calls a telephone call by activating the dial pulse generating relay contact.

The following explanation is as shown in figure C.

In the figure, 1 is a telephone and 2 is one hook switch. One end of the incoming call bell 4 is connected to the NC contact 3 of the switch 2, and the other end of the incoming call bell 4 is connected to the COM contact 8 of the dial pulse generation relay contact 7 via a resistor 5 and a capacitor 6. It is connected.

The NC contact 9 of the dial pulse generating relay contact 7 is connected to the telephone line IO. Reference numeral 11 denotes a telephone line that is paired with the telephone line 10 and is connected to the COM contact 12 of the hook inch 2. No contact 13 of the hook switch 2
is connected to the transmitter 14, the transmitter 14 is connected to the COM contact 17 of the external hook switch 16 via the resistor 15, and the No contact 18 of the hook switch 16 is connected to the hook-up detection circuit 19. Connected. The other end of the footer up detection circuit 19 is connected to C of the dial pulse generation relay contact 7.
Connect to OM contact 8. No. of the hook switch 16
One end of the handset 20 is connected to the contact 18, and the handset 20
The other end is connected to the No contact 13 of the hook switch 2 via a resistor 21 and a capacitor 22. A part of the footer up detection circuit 19 includes a dial memory part 2.
The other side of the dial memory part 23 is connected to a dial pulse generator 24 in which a dial pulse generator and a relay driver are incorporated. Both are connected so as to control the dial pulse generation relay contact 7.

An example of the basic structure of the footer-up detection circuit 19 is shown in FIG.

In FIG. 2, 25 is a rectifier diode, 26 is a Zener diode, 27 is a photocoupler, and 28 is a hook switch status monitoring output terminal.

The dial memory part 23 and the dial pulse generator 2
A block diagram of 4 is shown in FIG. 29 is memory IC1
3o is a dial selection IC 131 is a selection switch group,
32 is a reference clock pulse generation section, 33 is a dial pulse generation IC 134 is a relay drive -J111+-Run Sister, and 35 is a dial pulse generation relay coil.

Next, we will discuss the effect.

There are cases where the selection switch group 31 is provided inside the body of the telephone 1 and cases where it is provided outside the body.
Remove the bottom cover of the telephone 1 and operate the selection switch 31 group,
In the latter case, the group of selection switches 31 is operated directly. Ten selection switches 311\ are provided, and for example, when the telephone number is 0422-4975101, all of them can be selected. Therefore, by rotating it with your fingertips, the above 0422-4
Match to 9-5101. When the handset is lifted in this state, one hook switch 2 automatically connects to the NO contact 13, and the other hook switch 16 connects to the NO contact 18.
automatically connect to.

Therefore, a DC loop circuit is formed as follows: 1E telephone line 11 → hook switch 2 → transmitter 14 → resistor 15 → hook switch 16 → hook-up detection circuit 19 → dial generation relay contact 7 → telephone line 10 . Therefore, the rectifier diode 25 of the footer up detection circuit 19 works, and the photocoupler 27 detects the voltage set by the Zener diode 26 at its terminal, and outputs the state to the hook switch state monitoring output terminal 28. This output opens the read gate of the memory IC 29 shown in FIG. 3, and calls out the telephone number previously stored in the dial selection IC 30. Then, the telephone number is synchronized with the speed of the reference clock pulse generator 32 from the memory IC 29, and is sequentially outputted to the dial pulse generator IC 33. Then, the dial pulse generation IC 33 generates a corresponding pulse toward the dial pulse generation section 24, switches the relay drive transistor 34, and intermittently causes current to flow through the dial pulse generation relay coil 35. As a result, the dial pulse generation relay contact 7 is turned on and off, and a pulse signal is sent out.

As already mentioned, conventionally known butshuphone telephones have speed dials, and by dialing *00 three times, for example, it is possible to activate the tα device in the telephone office and make a call to the desired telephone number. there were. That is, if the telephone number of the called party was 0422-49-5101, the call could not be made unless the dial was rotated 10 degrees. 1
01h Tayal can be called by simply dialing *oo three times.

For example, between the Kisha packaging department and the factory production department, -1,1
I have been making many calls, but it is troublesome to dial and call the other party each time, so I use the xO speed dial to call the other party.However, 3
Due to the desire to shorten the dialing time and the switching of minds caused by dialing even speed dials, it is possible to forget important requirements, so we will focus on things that can be called without dialing at all. It will be done.

In other words, in addition to the purpose of saving time, calling the other party without dialing at all has various secondary effects that are immeasurable.However, the present invention provides (1)
An automatic ringing telephone, in which a storage device for a specific called telephone number is provided in the telephone, and the storage device is activated to automatically make a call when the handset of the telephone is lifted; ) A DC loop circuit formed by holding and picking up the handset is provided in the telephone, a hook-up detection circuit and a relay contact for dial pulse generation are provided in the DC loop circuit, and the hook-up detection circuit is a group of selection switches that can set the telephone number to be called;
A configuration of an automatic ringing telephone set in which a memory device consisting of a memory IC and a dial pulse generator are connected, and the memory device and the dial pulse generator operate the relay contact for dial pulse generation to automatically call a telephone. Therefore, there is no need to change your regular phone to a butshuhon phone.

Just by lifting the transmitting/receiving device of an ordinary telephone, you can summon the power of the other party.

Ha, when I call the other party because I have something to do, I end up dialing the phone number 10 times and then suddenly forget my important car and neglect important business negotiations. This will no longer happen.

Second, the structure is simple and can be formed at low cost.

This effect can be expected.
