Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a multifunctional telephone stage with many functions.

[Conventional technology]

Some multifunctional telephones of this type have a one-touch dialing function for making calls in one touch, in addition to a manual dialing function for making calls manually. An example of such a multifunction telephone is shown in FIG.

The conventional multi-function telephone shown in FIG.
an incoming call detection circuit 3 connected to the hook switch 2 and equipped with a sounder 4; a telephone call circuit 5 connected to the hook switch 2 and equipped with a transmitter 6 and a receiver 7; and a dial signal generation circuit 8 connected to the hook switch 2. , a dial control circuit 13 connected to the dial signal generation circuit 8 and comprising a one-touch button 9, a number registration button 10, a memory circuit 11, and a dial pad 12.

In a multi-function telephone with such a configuration, the memory circuit 11
is for recording the dial number. The dial control circuit 13 includes a one-touch button 9, a number registration button 10. The state of the dial pad 12 is read, the dial number is recorded in the memory circuit 11, and the memory circuit 11 is
The dial number written in tα is read out, and the dial signal generation circuit 8 is controlled to perform a dial operation.

When such a multifunction telephone receives an incoming call, the incoming call detection circuit 3 detects a calling signal from the telephone line 1, and drives the sounder 4 to generate a ringing tone.

The user turns the hook switch 2 off-hook by listening to the ringtone. Thereby, the telephone line 1 is connected to the telephone communication circuit 5, and a telephone conversation is possible using the transmitter 6 and the telephone receiver 7.

Next, when making a call, there are two methods: manual dialing using the dial pad 12 and one-touch dialing using the one-touch button 10.

First, in the case of making a call by manual dialing, after turning off the hook switch 2, the user presses down the dial pad 12 and inputs the dial number. As a result, the dial control circuit 13 recognizes the dial number, and the dial signal generation circuit 8
to drive. Due to this drive, a dial signal is sent to the telephone line 1 and transmitted to the other party via the exchange.

Next, in the case of one-touch dialing, it is necessary to register the dial number corresponding to the one-touch button 9 in the memory circuit 11 in advance. This operation is performed by pressing the number registration button 10.

Then, the dial control circuit 13 prepares for dial number registration, and records the number input using the dial pad 12 in the temporary storage ↑α area of the storage circuit 11. Then, by pressing the one-touch button 9, the corresponding storage area is moved again. This operation is necessary because there are a plurality of one-touch buttons 9.

In the case of a one-touch dial call after such registration is completed, the user turns off the footer switch 2 and then presses the one-touch button 9, causing the dial control circuit 13 to load the corresponding memory in the memory circuit 1. Read the dial number from the area. Then, the dial signal generation circuit 8 is driven to send a dial signal to the telephone line operator.

[Problem to be solved by the invention]

In the above-mentioned conventional multifunction telephone, a dial number is registered in advance using a one-touch button. When dialing, a dialing signal is generated with just one button press, simplifying dialing operations.

However, since restrictions on outgoing calls are reduced by simplifying the dialing operation, there is a drawback that this may induce more outgoing calls than necessary and increase communication costs.

Further, unless the registered dial number is recorded in the form of characters or the like at the time of registration, there is also the drawback that the contents cannot be confirmed unless the dial number is actually dialed.

It is an object of the present invention to eliminate such drawbacks and to provide a multi-functional telephone with call restriction, which allows the user to selectively limit the range in which calls can be made, and allows a specific user to change the call restriction range as needed. It is about providing.

[Means to solve the problem]

The present invention is a multi-functional telephone that can make normal calls using pre-registered numbers and can set call restrictions to restrict these normal calls, comprising: a storage unit that stores call restrictions; a setting unit that sets a password in advance; a switching section for switching between a normal call mode and a password mode; a display section for displaying input information; and when the switching section is in the password mode, comparing the password set in the setting section with the input password. Then, if a match is detected, register in advance! ! : It is characterized by having a control section that enables changing the number that is being sent and changing the call restriction in the storage section, and outputs information related to the change and information related to the call to the display section.

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

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

This multifunctional telephone is connected to a telephone port KfA 1, and includes a hook switch 2, an incoming call detection circuit 3, a sounder 4, a communication circuit 5, a transmitter 6, a receiver 7, and a dial signal generation circuit. 8, state control circuit 18, emergency button 14, one-touch button 9, number registration button 10, memory circuit 11, dial pad 12, mode changeover switch 15, display 16, password setting switch 17 In a multi-function telephone with such a configuration, the hook switch 2, the incoming call detection circuit 3, the sounder 4, and the telephone call circuit 5.
, a transmitter 6 , a receiver 7 , and a dial signal generation circuit 8
, one-touch button 9, number registration button 10, memory circuit 11, and dial pad 12 are the same as those of the conventional multifunction telephone shown in FIG.

The emergency button 14 is a button for dialing in an emergency.

The mode changeover switch 15 is a switch for switching between a normal call mode and a password mode. Normal call mode is one-touch button 9° dial pad 12
．． In this mode, the dial number in the memory circuit 11 is read out in accordance with the input of the emergency button 14, and a call is made in accordance with the regulation class data.

Note that the restriction class indicates a state in which calls can be made depending on the number from the dial pad 12, etc. For example, the number "
If the number is "1", only the emergency button 9 can be input, if it is "2", only the emergency button 14 and one-touch button 9 can be input, and if the number is "3", the emergency button 14. One-touch button9. Only the speed dial combination of the button "*" and two-digit number data can be input, and if the number is "4", all can be input. On the other hand, the password mode is a mode in which a password is input, a call restriction range is changed, a dial number corresponding to the one-touch button 9 is registered in the storage circuit 11, and the like. In the password mode, the number of the password setting switch 17 is compared with the password input from the dial pad 12, and guidance, etc. is output to the display 16 when changing the regulation class or registering the dial number in the memory circuit 11. be done.

The password setting switch 17 is a switch for presetting a password, such as a number, for identifying a specific user of the multifunction telephone according to this embodiment. This password setting switch sets a password unique to the multifunction telephone.

The display 16 is for displaying the restriction state, input guidance, and dial number output from the state control circuit 18.

The state control circuit 18 reads the state of the mode changeover switch and compares the number set by the password setting switch 17 with the number input from the dial pad 12. When the state control circuit 18 detects a match between these numbers, the state control circuit 18 transfers the control of the dial signal generation circuit 8 to the storage circuit 1.
The status is changed according to the status registered in 1, and the status is displayed on the display 16.

Next, the operation of this embodiment will be explained with reference to the time chart of FIG.

First, the operation in password mode will be explained. When the mode changeover switch 15 is set to the password mode (step S1), the state control circuit 18 reads the number preset in the password setting switch 17, and waits for a password to be input from the dial pad 12. At the same time, guidance such as "Please enter your password" is output on the display 16. When a password is input from the dial pad 12 (step S2), the state control circuit 18 compares the number previously read from the password setting switch 17 with the input password.

When a match between the password and the number is detected (step S3), the state control circuit 18 reads out the currently registered regulation class data from the storage circuit 11, and displays the data on the display 16.
Outputs the control class data of the heel.

The display 16 displays the restriction class when the restriction class data is input. When changing the restriction class according to this display (step S4), the user re-enters the number of the relevant restriction class, for example, any number from "1" to "4" (step S5).

Furthermore, if the user presses the button "#", for example, when the restriction class does not need to be changed, the process in step S5 is not performed and the step moves to the next step.

Next, the emergency button 14. When registering or changing the dial number corresponding to the one-touch button 9 (step S6
), the user presses the number registration button 10. In response to this press, the state control circuit 18 outputs guidance such as "Please enter the dial number" to the display 16, for example. When the user inputs a dial number from the dial pad 12 according to the display on the display 16 and then presses the emergency button 14 or the one-touch button 9, the state control circuit 1
8 registers the dial number in the area corresponding to the button in the memory circuit 11 (step S7). In addition, if there is no need to register or change the dial number, step S7
Processing is performed and the step moves to the next step. If the registration or change of the dial number is not completed (step S8), the step returns to step S7 again. When the registration operation is completed, or when the passwords do not match in step S3, the user returns the mode selector switch 15 to the normal call mode, and the state control circuit 18 waits for normal dial input.

Next, the operation in the normal call mode will be explained.

If the normal call mode is set in step S1,
Or after the end of step S8, the mode changeover switch 15
When returned to normal call mode, it waits for the user to make a call. When the user takes the hook switch 2 off-hook, the above-mentioned restriction class corresponds to the number "1" (
In step S9), when the user further presses the emergency button 14, the state control circuit 18 reads out the corresponding dial number from the memory circuit 11, drives the dial signal generation circuit 8, generates a dial signal, and displays the display. 16
The dial number is displayed (step 510). This completes the dialing operation. Further, when the one-touch button 9 is pressed, the state control circuit 18 outputs guidance such as "Unable to make a call. Please change the regulation class if necessary" to the display 16, and informs the user of the state. Display and request the next input. As a result, the user turns on the hook switch 2 and abandons the call, thereby completing the calling operation.

In step S9, if the restriction class is not "1", if the restriction class corresponds to the number "2" (step S9
), input from the emergency button 14 and one-touch button 9 becomes possible (step 512). If the restriction class is not “2” in step 311, then the restriction class is the number “2”.
3" (step 513), press the W emergency button 14. Input from the one-touch button 9 and speed dial becomes possible (step 514). If the restriction class is not "3" in step S13, all inputs are possible (step 515).

In this way, this embodiment registers the dial signal generation circuit in the memory circuit by comparing the number set by the password setting switch and the number input from the dial pad according to the state of the mode selector switch and detecting a match. It can be controlled according to the status, and the status can be displayed on the display.

〔Effect of the invention〕

As explained above, according to the present invention, the range in which calls can be made can be changed depending on the usage condition, it is possible to restrict unauthorized calls by unspecified persons, and necessary calls can be made without restriction to specified persons. This makes it possible to implement multi-level call control, which has the effect of reducing communication costs.

Furthermore, since the registered number can be confirmed on the display section, there is also the effect that the number can be easily changed.
