The present invention relates to an automatic tuning apparatus for a telephone of the present invention, in particular, in order to prevent a theft accident, by attaching a switch to a store's shatter (Doa) part and connecting it to a store's phone, when an intruder intrudes, the switch attached to the shatter part switches. The main focus was on making phone calls to places where the stolen accidents should be known (store owners' homes, police stations, etc.) so that they could be notified of unauthorized invasion.

Previously, in order to prevent theft, an alarm switch was attached to the door portion, and when an intruder invaded, an alarm was made to alarm the unauthorized intruder, or a nearby person was informed that there was an intruder. It can be useful in places where stores and homes are shared, but it can't be used when the store and the owner's home are far away. It had a flaw that prevented it from functioning as a burglar alarm.

The present invention automatically eliminates the above-mentioned burglar alarm device and prevents theft of the store, and automatically selects the store's phone and the owner's home phone so that unauthorized intruders invade the store. Since it is possible to take action afterwards so as to prevent theft, the following description will be made according to the accompanying drawings.

FIG. 1 is a block diagram of the present invention, in which a switching circuit (A) is formed by connecting a switch (S1) attached to a shatter portion to a gate of a thyristor (SCR), and the switching circuit (A) provides a delay time. A time circuit A, which is composed of a first time circuit 1, a second time circuit 2, and a third time circuit 3 which are sequentially driven and is switched by the first time circuit 1; And a fourth time circuit (4), connected to a repetitive time circuit (D) at the output of the fourth time circuit (4) and a switch (T) for tuning of the telephone, and the second time circuit (2). Is connected to the B time circuit B which selects the memory button of the stored telephone number.

The third time circuit 3 then selects the stored telephone number and connects it to the C time circuit C which finally enables the telephone call.

The relay RY ₁₀ (RY ₁₁ ) and the thyristor SCR ₂ are configured at the power supply terminal B ⁺ so as to be switched and supplied with the delay time set as the power supply circuit SM.

Referring to the operation and effect of the present invention having such a configuration as follows.

When the switch S ₁ attached to the shatter part is opened and turned off, the switching circuit is driven, and the switching circuit 1 has a set delay time and the first time circuit 1 and the second time. The circuit 2 and the third time circuit 3 operate sequentially.

When the first time circuit 1 is operated, the A time circuit A is driven after the delay setting time (about 2 seconds) and the fourth time circuit 4 is driven after the delay time (0.5 seconds). By the operation of the fourth time circuit 4, the hook switch T for the first channel selection is switched, and at the same time, the repetitive time circuit D is switched to switch at a set time interval (1 minute) so that it is set at the same time. It keeps you informed that there is an intruder by letting you keep the call at intervals of one minute.

Then, the second time circuit 2 is driven after the delay time (1 second) after the first time circuit 1 is driven, and after the set time (0.5 seconds) by the driving of the second time circuit 2. The B time circuit B operates to select the telephone memory button switch TM.

The third time circuit 3 is driven after the delay time (1 second) after the second time circuit 2 is operated, and the C time circuit after the set time (0.5 seconds) by the driving of the third time 3. (C) operates to select the button switch (TEL) of the memorized phone to make a phone call to be notified of theft accident at last.In this case, attach the amplifier to the talker and switch the amplifier to switch the voice or object of the intruder. Even the small sound of moving the sound is notified to the tuned telephone through the handset.

In this way, when an unauthorized intruder invades the store by using the telephone of the store, the home telephone can be tuned. Referring to FIG. 2, which is a circuit diagram of an embodiment for explaining the present invention in more detail as follows.

Connect the off switch (S ₁ ) connected to the ground point to the gate of the diester (SCR), connect the relay (RY ₁ ) to the die thyristor (SCR), and then resistance the relay (RY ₁ ) contact (Y ₁ , Y ₂ ).
