DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone connected to an analog telephone line.

[0002]

2. Description of the Related Art In telephones and the like connected to an analog telephone line, since the telephone number of the calling side is not known, there are many damages such as prank calls.

For this reason, in recent years, a calling number notification service has been proposed in which an analog telephone line network notifies the calling side telephone number to the called side line so that the called side can confirm the calling side telephone number. I have. This service is provided by a contract between the receiving party and the line provider, and if the calling party normally calls the telephone line receiving this number notification service without being aware of the calling party, the calling party's The telephone number will be notified to the called party.

[0004]

However, there are cases in which it is not necessary to notify the called party of the telephone number of the calling party unconditionally.
For example, a telephone (so-called pink telephone) installed in a store or the like can be used by an unspecified person such as a customer of the store in the same manner as a public telephone, and the installer can use the same as a general subscriber telephone.
In this case, it is inconvenient for the installer that the caller of the shop knows the phone number of the shop when making and using the call because the number of calls to the customer increases.

In order to eliminate such inconvenience, there is also provided a service in which the network does not notify the caller's telephone number when a specific number is input prior to the input operation of the telephone number. Having the customer enter the number would be inconvenient for the customer, and the installer would have to constantly monitor the use of the phone.

Therefore, it is conceivable to configure a telephone so that a specific number is automatically added when a call is used. The number is no longer reported.

An object of the present invention is to solve this problem and to provide a telephone which allows a specific person to arbitrarily switch between a mode in which a specific number is automatically added and a mode in which a specific number is not added when using a call. I have.

[0008]

According to a first aspect of the present invention, there is provided a telephone having a telephone number input means for inputting a telephone number, the telephone being connected to an analog telephone line. A specific number memory in which a specific number for preventing a telephone number of an analog telephone line from being notified to a called party; and a number transmission mode arbitrarily set to one of a first number transmission mode and a second number transmission mode. Number sending mode designating means for designating, and which of the first and second number sending modes is designated as the number sending mode when an off-hook operation or a telephone number input operation by the telephone number input means is performed. Determining means for determining whether the telephone number input mode is the first number transmitting mode. By adding the specific number to the beginning of the input telephone number is sent to the analog telephone line from
When the determination means determines that the number transmission mode is the second number transmission mode, the telephone number input from the telephone number input means is transmitted to the analog telephone line without adding the specific number. Telephone number sending means.

A telephone according to a second aspect of the present invention comprises a master unit connected to an analog telephone line, and a slave unit wirelessly connected to the master unit, and a telephone number for inputting a telephone number. In a telephone provided with the input means in the master unit and the slave unit, the master unit has a specific number memory that stores a specific number in advance so as not to notify the receiving side of the telephone number of the analog telephone line, Number sending mode designating means for arbitrarily designating the number sending mode of the master unit and the slave unit to one of a first number sending mode and a second number sending mode; When an off-hook operation or a telephone number input operation by the telephone number input means is performed, it is determined which of the first and second number transmission modes is designated as the number transmission mode of the machine. Determining means, and when the determining means determines that the number transmission mode is the first number transmitting mode, adds the specific number to the head of the telephone number input from the telephone number input means of the machine. To the analog telephone line, and when the determination means determines that the number transmission mode is the second number transmission mode, the telephone number input means of the machine does not add the specific number.

As if 0 is off-hook operation, a determination of the transmission flag of the handset when the telephone number from the dialer 42 of hook child machine (40 ₁ or 40 ₂₎ is input, the determination result In response, the telephone number is transmitted to the telephone line L to perform a collection call process.

A network that receives a call prefixed with a specific number N from the master unit 20 or the slave unit 40 of the telephone set is connected to the telephone line even if the other party's line receives the calling telephone number notification service. The call is made without notifying the telephone number of L to the other party.

As described above, in this telephone, when the master unit 20 or the slave unit 40 is operated off-hook and the telephone number is input, the number transmission mode of the master unit 20 or the slave unit 40 is determined. Since a telephone number is transmitted with a specific number added according to the result of the determination, the number transmission mode is designated in advance so that the master unit and each slave unit are allocated to the customer and the installer for the assignment. By doing so, it is not necessary for the customer to input a specific number or for the installer to constantly monitor the telephone.

In this telephone, the base unit 20 is shared by the customer and the installer, and the slave unit 40 is exclusively assigned to the customer and the installer. This assignment can be arbitrarily made by changing the flag data. Can be changed. For example, the sending flags of all the slaves 40 may be set to “1” and the slaves may be dedicated to the installer. Further, in the above embodiment, the collection flag of the slave unit and the sending flag are matched, but a slave unit which does not collect a fee even if it is dedicated to a customer, or a slave which does not add a specific number but collects a fee. It is also possible to set the machine.

[Other Embodiments] In the above-described embodiment, a telephone of a toll collection type comprising a base unit 20 connected to an analog telephone line and a slave unit 40 connected to the analog telephone line via the base unit 20 will be described. As described above, the present invention can be similarly applied to a telephone which is not a toll collection type. Also, in the case of a telephone having no handset, it is usually set to a number transmission mode in which a specific number N is added, so that only a specific person can perform a code input operation or a specific person possesses the code. The key may be operated to temporarily switch to a number transmission mode for transmitting a telephone number without adding a specific number.

In the above embodiment, the key switch 30
Is turned on and the code C is input from the dialing device to change and specify the number transmission mode. However, the number transmission mode of the master unit and the slave unit is specified by a switch provided inside the telephone. It may be.

In the above embodiment, the number transmission mode is determined when the first digit telephone number is input from the dial device. However, when a plurality of digits are input, the number transmission mode is determined. Alternatively, the number transmission mode may be determined when the master unit or the slave unit is operated off-hook.

In the above embodiment, a dial device is used as a means for inputting a telephone number. However, a card reader for reading a telephone number stored in a card is used as a telephone number input means. Is also good.

[0035]

As described above, according to the first aspect of the present invention,
The telephone number transmission mode can be arbitrarily designated as one of the first and second number transmission modes, and the number transmission mode when an off-hook operation or a telephone number input operation is performed is set to the first number transmission mode. When it is determined that the telephone number is input, a specific number for preventing the caller's telephone number from being notified is added to the head of the input telephone number, and the telephone number is transmitted to the analog telephone line. Sometimes, a telephone number input without adding a specific number is transmitted to an analog telephone line.

Therefore, it is possible to arbitrarily switch between a mode in which a specific number is automatically added and a mode in which no specific number is added at the time of using a call, and even if the mode is used in common with an unspecified person, the unspecified person It is not necessary to input a specific number to the user or to monitor the use of the telephone.

Further, in the telephone according to the second aspect of the present invention, the number transmission mode of the master unit and the slave unit can be arbitrarily designated to one of the first and second number transmission modes, respectively. When an off-hook operation or a telephone number input operation is performed on the machine, and when it is determined that the number transmission mode of the machine is the first number transmission mode, a caller telephone is added to the head of the telephone number input from the machine. A specific number to prevent the number from being notified is added and transmitted to the analog telephone line, and when it is determined that the mode is the second number transmission mode, the telephone number input from the machine is added without adding the specific number. It is sent to the line.

Therefore, it is possible to arbitrarily set either a mode in which a specific number is automatically added to the master unit and the slave unit when using a call and a mode in which a specific number is not added. When used in common with a telephone, there is no need for an unspecified person to input a specific number or to monitor the use of a telephone.
