Abstract

PURPOSE:To send an alarm output by the non-detection output of the detecting means and to prevent the generation of the wrong call due to the dial misoperation by detecting with a detecting means whether or not the contents of a register to store temporarily the dialed telephone number are in the memory circuit to store the telephone number. CONSTITUTION:When a telephone number sent by the push button dial 4 of a telephone set is stored into a register 5 temporarily, a detecting circuit 9 detects whether or not the contents are in a memory circuit 6. By the non- detecting output of the detecting circuit 9, an alarm is sent to a receiver 2 connected to a telephone line 3 from an alarm generating circuit 10. Thus, an alarm is generated by the detected result whether or not the dialed telephone number stored temporarily to a register 5 is stored in the memory circuit 6 to store the telephone number, the generation of the wrong call due to the misoperation of the dial can be prevented.

Description

[Detailed description of the invention] [Industrial application field] The present invention is applied to telephones other than public telephones.

〔overview〕

The present invention provides a telephone set that detects whether or not the telephone number is in the memory circuit when making a dial call, and issues an alarm if the telephone number is not stored in the memory, thereby informing the caller of an error in the dialing operation. This is what I did.

[Conventional technology]

With conventional telephones, it is possible to automatically dial a call by storing a telephone number in advance and inputting a keyword. However, it was not possible to know whether a manually dialed phone number had been called before.

[Problem that the invention seeks to solve]

However, when dialing a telephone number that is frequently called, such as to a friend's house, from memory, there is a drawback that even if the user makes a mistake, the user can call the other party without realizing it, and the user can talk to the other party.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone that can solve this drawback and prevent the occurrence of mistaken calls due to dialing errors.

[Means for solving problems]

The present invention provides, in a telephone equipped with a memory circuit for storing one or more telephone numbers and a register for temporarily storing dialed telephone numbers, a detecting means for detecting whether the contents of the register are present in the memory circuit; , and an alarm means for sending out an alarm output based on the non-detected output of the detection means.

[Effect]

The dialed phone number is temporarily stored in a register and
It is detected whether this is present in the telephone number stored in the memory circuit. If there is, no alarm output will occur.

When dialing a telephone number manually, the caller is conscious of whether or not the number is frequently used, so if no alarm is output, it is important to check that the dialing operation is correct. recognize.

If the dialing operation is incorrect, an alarm will be output since the operated telephone number is not in the memory circuit.

Therefore, the caller realizes that there is a mistake.

〔Example〕

Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of the above embodiment.

In this figure, the telephone is operated by operating a transmitter 1, a receiver 2, a telephone circuit 3, a pushbutton dial 4, a register 5 that temporarily stores a dialing signal including a telephone number sent by the pushbutton dial 4, and a pushbutton dial 4. It includes a storage circuit 6 that stores one or more telephone numbers and a control section 7 that controls them.

The memory circuit 6 is used for speed dialing operations.

The present invention is characterized by a detection circuit 9 that detects whether the telephone number sent by the pushbutton dial 4 is stored in the memory circuit 6 when the telephone number sent by the pushbutton dial 4 is temporarily stored in the register 4; The present invention also includes an alarm generating circuit 10 which sends an alarm to the receiver 2 when there is no detection output from the circuit 9, that is, when there is no output in the memory circuit 6.

The alarm generation time of the alarm generation circuit 10 is set to a short time, for example, about 2 seconds.

When the caller dials the other party for the first time, if the other party does not need to be called frequently thereafter, the caller will immediately read the other party and make a call even if the above alarm occurs. . Since the alarm only occurs for a short time,
There is no problem with calls.

If it is necessary to make frequent calls, the user operates the function buttons on the pushbutton dial to dial (eg, *0OO-0000*). Through this operation, the required telephone number is stored in the storage circuit 6.
4. Afterwards, when this telephone number is dialed from memory, if the above-mentioned alarm occurs, it will be recognized that there was an error in the dialing operation, and the connection to the line 8 can be disconnected by going on-hook.

As another embodiment of the present invention, by inputting a clock signal to the control section 7, a telephone number operated for the first time can be automatically stored in the storage circuit 6.

That is, if it is not possible to talk to the other party after dialing, or if the call is for a short time (for example, 10 seconds or less), automatic input is not performed.

FIG. 2 is a control flowchart according to this other embodiment.

〔Effect of the invention〕

As explained above, according to the present invention, erroneous dialing operations can be recognized by an alarm, so that there is an effect that clumsiness in calling the wrong party and wasted time required for calling the wrong party can be reduced.
