Abstract

PURPOSE:To control origination optionally as necessary by providing a storage means where a password number is registered and inhibiting dial origination unless the password number is inputted with keys when the password number is registered. CONSTITUTION:When a handset is lifted and dial keys are operated, a control part 3 decides whether or not a password number is registered in the storage means 4. When no password number is stored in the storage means 4, a dial origination part 7 is driven on the basis of a key signal inputted with dial keys to output a dial signal to a trunk line channel. When a password number is registered in the storage means 4, and key input number is read and the registered password number is read out of the storage means 4; and a matching means 5 is put in operation and the dial origination part 7 is driven when the both coincide with each other to output the dial signal to the trunk line channel on the basis of said key input signal.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to so-called home telephones used primarily at homes, offices, and the like.

2. Description of the Related Art In general, home telephones are not equipped with means for restricting outgoing calls.

Problems to be Solved by the Invention Therefore, with this type of telephone, anyone can use the telephone freely, making it extremely difficult to manage telephone charges and the like.

The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide an excellent telephone set that has a simple configuration and can arbitrarily restrict outgoing calls as necessary.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a storage means for registering a PIN number, and when a PIN number is registered here, the PIN number is entered by key in advance. The system is configured so that dialing cannot be made without this.

Therefore, according to the present invention, by setting a personal identification number for each telephone and each user and registering these in the storage means of each telephone, calls can be made arbitrarily for each telephone and each user. It has the function of being able to be regulated and easily prevented from being used by others without permission.

Embodiment FIG. 1 is a schematic diagram of an embodiment of a telephone according to the present invention. In Fig. 1, 1 is a keyboard equipped with a dial key, a password registration key, a password deletion key, etc.;
3 is an input means that monitors which key has been operated on the keyboard 1 and transmits the result to the next stage; 3 is a control section comprising a microcomputer or the like that receives information from the input means 2 and controls each section; 4 is a control section; A storage means for registering a password; 5 a verification means for checking whether the password stored in the storage means 4 matches the password entered by the keyboard 1; 6 a verification means for the verification means 5; Call restriction means 7 restricts subsequent key inputs based on the result, and reference numeral 7 denotes a dial transmission section that outputs a dial signal in response to a key input from keyboard 1 when call restriction means 6 does not restrict calls.

Next, the operation of the above embodiment will be explained.

First, when registering a password in the storage means 4, a password registration key provided on the keyboard 1 is operated, thereby putting the entire device into a password registration mode. and,
If the user subsequently operates the dial key and inputs the password, the input password is stored in the storage means 4 by the action of the control section 3.

In addition, in the above embodiment, the storage means 4 is configured so that a 4-digit PIN number can be registered. Therefore, if a PIN number of 5 digits or more is keyed in, only the previous 4 digits will be registered and the 5-digit PIN number will be registered. It will be ignored thereafter.

In this manner, by registering the password in the storage means 4 and operating the password registration key again, the entire device is released from the password registration mode and the entire password registration operation is completed.

Next, a case will be described in which a dial call is made with the password registered in the storage device 4 in this manner. First, when the handset is lifted and the dial key is operated, the control section 3 determines whether or not a password is registered in the storage means 4 (step 8 in FIG. 2). If the PIN number is not registered in the storage means 4, the second
The process moves to step 15 in the figure, and the dial transmitter 7 is driven based on the signal input using the dial key, and outputs a dial signal to the central office line communication path.

If a password is registered in the storage means 4, the key-input number is read in step 9 of FIG.
In step 10, the password registered in the storage means 4 is read out, and in step 11, the verification means 5 operates,
Verify whether the two match. Steps 9 to 11 in FIG. 2 are performed for each digit of the key-input number, and in step 12 it is determined whether all digits have been verified. If all digits have not been matched (in this case, the process returns to step 9 again to perform the match, and if all digits have been matched, step 13 determines whether the two match for all digits). If the two match for all digits, the process moves to step 15, where the dialing unit 7 is driven based on the subsequent key inputs, and the central office line is switched based on the key input signals. A dial signal is output to the communication path.If the two digits do not match even by one digit, the process moves to step 14, where no further key input is accepted and dialing is not performed.

In this way, according to the above embodiment, when a PIN number is registered in the storage means 4, if the PIN number is not entered correctly using the dial keys, it will not be possible to enter the number to make a call later. The call will not be accepted, and only a person who knows the PIN number will be able to make a dial call. If the PIN number is not registered in the storage means 4, all signals entered using the dial keys are accepted and dialing can be made, so in this case it can be used like a normal telephone. can.

Further, in the above embodiment, the password stored in the storage means 4I is configured so that it can be easily deleted by operating a key for deleting the password. Therefore, even if a password is once registered in the storage means 4, it can be easily deleted and used as a normal telephone. If the user wishes to change the registered password, he or she can easily change it by registering a new password. .

In the embodiment, a registration key and a deletion key are operated to register and delete a password, respectively, but other keys may be used. Further, although not explained in the embodiment, when a password is registered in the storage device, only the registered password may be automatically displayed on a display or the like.

Effects of the Invention As is clear from the embodiments described above, the present invention is provided with a storage means for registering a PIN number, and only when the PIN number is registered in this storage means, dialing is performed unless the PIN number is entered by key in advance. It is configured so that calls cannot be made,
Therefore, according to the present invention, it is possible to easily prevent inconveniences such as unintentional increase in telephone charges due to someone using the telephone carelessly, and also to avoid registering the password in the storage means. It can be used arbitrarily in the same way as a normal telephone, and is extremely advantageous in practice.
