Abstract

PURPOSE:To increase/decrease or revise a dial restriction destination at any time by collating registration data stored in a storage means with dial number data and restricting the dialing only when they are coincident. CONSTITUTION:A registration key 2 and a dialing restriction key 3 of a key operation section 1 are operated to store data including an access number in plural digits of a destination to which dialing is going to be restricted to a memory 7 of a dial control circuit 6. When the dial key 4 is operated in this state and a dial number is inputted, the data are collected with registration data stored in the memory 7, and when the dial number data and the registration data are coincident, the circuit 6 restricts dialing. Since the dialing restriction is selectively set in advance in this way, the dialing restriction is increased/ decreased/revised at any time and the convenience is enhanced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunction telephone,
In particular, the present invention relates to a telephone call restriction device that allows a user to arbitrarily increase or decrease the call restriction destination.

[0002]

2. Description of the Related Art Recently, a multi-function telephone having a built-in outgoing call control device has been used in consideration of the fact that a so-called long telephone monopolizes a telephone line for a long time and a long call is charged for long distance. ing.

As an example of this type of telephone, as shown in FIG. 3, a call regulation device having a function of regulating only long distance calls and a function of regulating all outgoing calls has been proposed.

In this transmission restriction device, dial number data input by key operation by the key operation unit 20 is temporarily stored in the buffer memory 21,
The output of the buffer memory 21 is the transmission restriction switch 2
It is connected to two movable contacts a.

The transmission restriction switch 22 is switched by the operation of a switching operation unit (not shown) provided in the main body of the telephone, and all prohibited contacts b for restricting all transmissions and the first of the input numbers. It is provided with an out-of-city contact point c that restricts outgoing calls only when there is 0, and a free contact point d that sends outgoing calls without restricting outgoing calls. The out-of-city contact c is led to a zero transmission regulation circuit 23 that regulates zero transmission. The output of the zero transmission regulation circuit 23 and the free contact d are signal transmissions for transmitting dial pulse and dial tone signals. It is connected to the circuit 24.

However, in this transmission control device, when the user operates the switching operation section to switch the transmission restriction switch 22 to an arbitrary position, the dial number input from the key operation section 20 is stored in the buffer memory 21. After being temporarily stored in
It is sent to each part through the selected contact of the transmission restriction switch 22. For example, if all prohibited contacts are b, outgoing calls cannot be made to the outside line, and if there is no forbidden contacts c, outgoing calls are restricted only to those with 0 at the first input number, and other local calls are possible. Becomes Further, the free contact point d enables an international call or the like without any restrictions.

As described above, since it is possible to restrict only the out-of-city number and all outgoing calls, it is possible to prevent the possibility of making a long phone call or a long distance call in advance. ..

[0008]

However, the above-described conventional transmission restriction device has a problem that the restriction target is limited to the number of contacts of the switch 22, and thus fine control cannot be performed. For example, if the all-prohibited contact point b is set in advance in order to prevent a child's long phone call, the parent himself / herself cannot make a dial call, which causes inconvenience. Also, if the contact point is out-of-city c, it is necessary to regulate Tokyo because it is a remote place, but since it frequently goes to Osaka, it is impossible to use it according to the fact that it is not necessary to regulate.

[0009] Furthermore, regarding international calls, it is always desirable to regulate outgoing calls, but there is a limit that these two requirements cannot be met when the long distance calls need to be free. In order to make this possible, it is sufficient to increase the number of contacts of the transmission restriction switch 22, but if the number of contacts increases, the structure becomes complicated and the switching operation is required for the increased number of contacts, which makes the handling troublesome. The problem such as was left.

The present invention has been made in view of the above situation, and an object thereof is to provide a call origination restricting device for a telephone in which a user can arbitrarily increase or decrease the call restriction destination.

[0011]

In order to solve the above-mentioned problems, a transmission restriction device for a telephone according to the present invention comprises a registration means for outputting data including a plurality of digit access numbers which are sequentially key-operated when dialing. The storage means for storing the data from the registration means as the registration data corresponding to the transmission restriction target and the registration data stored in the storage means and the dial number data input by the key operation are collated, and the data are matched. Only when the call is made, the call control means for controlling the call of the dial number is provided.

[0012]

The user of the telephone uses the registration means to previously register the other party whose transmission is to be restricted. For example, an area code or a number such as a dedicated communication line is sequentially input by operating a plurality of digits from the upper digit. This number data is stored in the storage means as registration data corresponding to the call restriction target.

In this state, when another user inputs a dial number by key operation, this dial number is collated with the registration data stored in the storage means. Here, when the dial number data and the registered data match, the transmission control means determines that this dial number is subject to transmission restriction and restricts dial transmission.

On the other hand, if the dial number data and the registered data do not match, it is judged that the call is not regulated and the dial call is permitted.

The restriction and permission of such outgoing call can be selectively set in advance by the user of the telephone and can be changed at any time by operating the registration means.

Further, it is possible to increase the number of call restriction targets by arbitrarily combining data including a plurality of digits of access numbers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the electrical construction of a transmission restriction device for a multifunction telephone.

In the figure, reference numeral 1 denotes a key operation section which also serves as a registration means, and its output is given to a transmission control circuit 6 and a buffer memory 5. The key operation unit 1 includes a registration key 2 and a transmission restriction key 3 in addition to the dial key 4.

The registration key 2 is used to perform a registration operation of the call restriction destination, and although not shown in the figure, the transmission control circuit is provided via a registration processing unit that performs various registration processes such as a code number and auto dial. It is connected to 6 and shifts to the registration mode by key operation. Further, the call restriction key 3 is for restricting the call of the dialed number. When the call restriction key 3 is operated subsequent to the registration key 2, the number entered by the dial key operation is controlled as the call restriction. It is adapted to be stored in the memory 7 of the circuit 6.

The transmission control circuit 6 stores a memory 7 for storing registration data, a collating unit 8 for comparing the registration data in the memory 7 with input data of a dial number by key operation, and controls the operation of the entire device, and also makes a dial transmission. It is configured to include a control unit 9 that controls or permits the control.
The control unit 9 is bidirectionally connected to the memory 7 and the matching unit 8.

Further, the input of the control unit 9 is guided by the output of the buffer memory 5 for temporarily storing dial number data input by operating the dial keys 4. The output of the control unit 9 is connected to a signal transmission circuit 10 for generating dial pulse and dial tone signals, and the output of the signal transmission circuit 10 is connected to a telephone line via a transmission / reception unit. Furthermore, the output of the control unit 9 is connected to a voice guide unit 11 that guides that the number is a call-restricted number.

The voice guide unit 11 is constituted by including a voice synthesis analysis circuit, operates by receiving a control signal from the control unit 9, and outputs a guidance message "I cannot make a call to this number" from the speaker 12. Make it sound. In addition, the voice guide unit 11 can emit a guide message "The operation is wrong" from the speaker 12 in response to the control signal sent from the control unit 9 when the user makes an error in the operation procedure. It is composed.

Next, a call origination restricting operation of the multi-function telephone having the above configuration will be described.

First, a call restriction target is registered prior to use. In this case, the user inputs the registration key 2 of the operation unit 1.
And then the transmission restriction key 3 are operated. As a result, the registration mode of outgoing call restriction is entered, and a large number of registrations are possible when the user inputs the access number of the destination to be restricted by the dial key.

Specifically, it is a combination of up to 4 digits of number data of upper 3 to 4 digits including an access number which is sequentially operated by a key at the time of dialing, and a pause by operating a pause key (not shown). The registration operation is performed corresponding to the call restriction target described in the table shown in FIG. Here, the reason why the combination of four digits is used is that the access number has a four-digit configuration in many cases, but it is not necessarily limited to four digits.

In this example, when the regulated object is the dial Q ² , the access number is “0990”, and when this key operation is performed, this number data is sent from the control section 9 to the memory 7 and stored therein. .. In the case of KDD, "00
When the pause key is operated after "1", data "001 pause" which is a combination of the number and the pause is sent to the memory 7 and stored as registration data corresponding to the transmission restriction target.

The registration of such outgoing call restriction can be increased or decreased by selectively combining the upper digits of the access number and the pause, and the registration range can be greatly increased within the capacity of the memory 7. is there.

Next, when another user initiates a telephone call and performs a dial operation with the dial key 4, this dial number is collated with the registration data stored in the memory 7 in the collation unit 8. Here, if the dial number data and the registered data match, the control unit 9 determines that this dial number is subject to call regulation, and regulates dial transmission. Therefore, this dialed number is never sent from the signal transmission circuit 10 to the telephone line. Further, at this time, a control signal is sent from the control unit 9 to the voice guide unit 11, and the speaker 12 gives a guidance "I cannot make a call to this number."

On the other hand, if the dial number data and the registered data do not match, the control unit 9 judges that the call is not regulated and permits dialing. Along with this, the dial tone and dial number are sent from the signal transmission circuit 10 to the telephone line.

In the above-mentioned embodiment, the call restriction of other users is restricted by registering the call restriction object, but the call restriction may be turned on / off by remote operation.

[0032]

The transmission restriction device for a telephone according to the present invention can finely regulate the transmission according to the convenience of each user by registering the transmission restriction target in advance. For example, a local area code or short-distance area code can be freely sent, and long-distance area codes or dedicated communication lines such as dial Q ² are subject to transmission restrictions, and remote areas or expensive lines are used. Can be prevented.

Further, in order to regulate such a call, it is sufficient to register the upper digit data including the access number in an arbitrary combination, so that it is possible to change it at any time, which enhances the convenience, and in addition to the conventional method. There is also an effect that it is possible to significantly increase the types of call restriction targets as compared with the case where a call restriction switch or the like is used.
