Abstract

PURPOSE:To prevent operation mistakes by providing an informing device offering notice with a specific display or a specific notice tone if a function of a function key is not performed regardless of its operation in a telephone set provided with function keys such as a registration key. CONSTITUTION:A telephone number is registered by operating a registration key of a function key 1 to input a registration command signal to a control function section 3, the section 3 discriminates the presence of an unregistered area to apply registration functions to a storage device 4 and when the unregistered area exists, the user operates a data key 2 and registers it on the unregistered area. When no unregistered area exists in the device 4, it is displayed on a display section 5.

Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to a multifunctional telephone equipped with function keys such as a registration key for registering a telephone number, a shortcut key for making a shortened call, and a redial key for making a redial call. <Prior art> In conventional multi-function telephones equipped with this type of function keys, when registering a telephone number by operating the registration key, which is a function key, it is difficult to know whether there is an unregistered area. Therefore, there is a risk of accidentally deleting the registered contents (old registered contents) that have been registered in advance, and there is also a risk of accidentally deleting the registration contents (old registered contents) that have been registered in advance. There is a disadvantage that even if the speed dial number is not registered and speed dialing is not possible, you may not notice and wait for the other party to answer, and this also applies when you operate the redial key, which is a function key, to make a redial call. There was a drawback that even if the last number called was not in the memory area and redialing was not possible, the user would not notice and wait for the other party to answer.0 <Object of the Invention> The present invention provides a telephone that eliminates the above-mentioned drawbacks. The purpose is to provide the following.

<Embodiments of the invention>.

An embodiment of the telephone according to the present invention will be described below with reference to the drawings.

The telephone set of the present invention is constructed as shown in FIG. 1, and in FIG. 1, reference numeral 1 indicates a registration key for registering a telephone number, an abbreviation key for making a shortened call, a redial key for making a redial call, etc. 2 is a data key for inputting data such as phone number 1 identification information (for example, 1-2 digit numbers or several digit characters), and 3 is a data key for inputting data such as telephone number 1 identification information (for example, 1-2 digit numbers or several digit characters), and 3 is a data key for inputting data such as telephone number 1 identification information (for example, 1-2 digit numbers or several digit characters), and 3 is a data key for inputting data such as telephone number 1 identification information (for example, 1-2 digit numbers or several digit characters) Inputting predetermined data into the storage device 4 or outputting predetermined data from the storage device 4 by operating the key 1 and the data key 2 to control the predetermined function commanded by the function key 1. An unregistered area for performing a predetermined function commanded by the function key ■ of the storage device 4, or an unregistered area for determining the presence or absence of a registered area and performing a predetermined function commanded by the function key ■. Or, if there is no registration area, the display device 5 will display, for example, “
? ? ? A display indicating that there is no J etc. or speaker 6 to H
FIJ is a control function section that controls the generation of a buzzer sound such as "beep beep beep".

The operation of the telephone configured as described above will be explained with reference to the flowchart in FIG. input, the control function unit 3 determines whether there is an unregistered area in the storage device 4 for performing the registration function,
If there is an unregistered area, the user operates the data key 2 to input the telephone number and identification information into the control function section 3,
The control function unit 3 registers it in the unregistered area of the storage device 4. In this case, when the registration key is operated, the storage device 4
When there is no unregistered area, the control function unit 3 displays the display device 5, for example, r? ? ? When the display indicating that there is no J etc. is performed, the speaker 6 generates a buzzer sound such as "beep beep" to inform the user of this fact.

To explain the above operation using the detection of whether or not an abbreviated number is registered as an example, when the registered contents are deleted, the 4-bit storage device (memory) of the start address of the registered area is
When registering a telephone number by writing "F (To)" in 4, when the registration key of the function key ■ is operated, the control function section 3 stores the contents of the storage device 4 at the start address of the registration area.
F (II)”, and if so, check the unregistered area, childlessness, and user identification information (for example, 1 to 2).
digits) and phone number using data key 2 to register. Then, the discrimination information (for example, "000" to "901" is stored in the storage device 4 at the start address of the registered area.
”.

The contents of the storage device 4 at the start address of the registration area are @F(
If not "1.", check the contents of the storage device 4 at the start address of the next registration area and perform the same judgment and processing.0 If the contents of the storage device 4 at the start address of all registration areas are "F0e" Otherwise, if there is no unregistered area, the control function unit 3 displays on the display device 5 that there is no unregistered area,
A buzzer sound is generated from the speaker 6 to notify the user.

To make an abbreviated call, operate the abbreviated key of the function key 1 and operate the data key 2 to input the abbreviated command signal and the discrimination signal to the control function section 3. It determines whether there is a corresponding area among the registered areas in 4, and if there is a corresponding area, performs a shortened call operation,
If there is no corresponding one, the control function unit 8 displays on the display device 5, for example, "???", and the system power 6 generates a buzzer sound such as "pi-pi-pi". The user will be informed of this.

Then, to make a redial call, operate the redial key of function key l to input a redial command signal to the control function unit 3, and the control function unit 3 determines the presence or absence of the previous call number from the storage device 4, and If there is a corresponding one, a redial operation is performed, and if there is no corresponding one, the control function unit 3 displays on the display device 5, for example, " A buzzer sound such as "beep beep" is generated to notify the user.

As described above, with the telephone of the present invention, there is no risk of accidentally deleting old registered information, and if a number that is not registered by mistake is dialed during short dialing, the user will immediately notice the error through a display or a buzzer. can be operated correctly. If the redial call is invalid, the error can be noticed immediately by a display or a buzzer, and the call can be made by another method immediately.

<Effects of the Invention> Since the telephone of the present invention has the above-described configuration, if a function cannot be performed by operating a function key, a notification to that effect is provided, thereby eliminating mistakes in use.
