DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone connected to a private branch exchange, and more particularly to simplification of an operation for selecting an outside line and an extension.

[0002]

2. Description of the Related Art When a call is to be made from a telephone connected to a private branch exchange to an outside line, first operate a dial "0" indicating the outside line to connect to the outside line and then dial the telephone number of the other party. doing.

[0003]

As described above, in the conventional telephone, the dial "0" indicating an outside line must be operated before dialing the telephone number of the other party. In such a case, the user must go off-hook and then perform the dial operation again, which is troublesome and wastes time.

An object of the present invention is to provide a telephone capable of eliminating such troublesome operations and reducing erroneous operations.

[0005]

A telephone according to the present invention comprises a dial key, a line instruction switch, and a destination number storage.
Means, a line storage means, and a control means.
Dial key to enter the number of the destination
Line indication switch is the line of the other party to enter with the dial key
Indicates the outside line or extension, and the destination number storage means
Ruki - storing the entered destination number, the line storing means stores the line indicated by the line instruction switch, control hand
The columns correspond to the destination number storage means and the line storage means, respectively.
Call the destination when the destination number and the line of the destination are stored
When the communication ends and the phone goes on-hook,
The contents stored in the signal storage means and the line storage means are erased .

Further, it is preferable that the control means reads out and sends out the line stored in the line storage means, and then reads out and sends out the other party telephone number stored in the other party number storage means.

[0007]

[0008]

In the present invention, the line to be transmitted and the destination number are stored in the line storage means and the destination number storage means, respectively, so that the line to be transmitted can be designated before or after inputting the destination number. Can be.

Further, the destination number is stored in the destination number storage means until the transmission line is stored in the line storage means. Then, when the line to be transmitted is stored in the line storage means, the line to be transmitted is read out and sent out, and then the destination number is read out and sent out and transmitted to the destination. The contents stored in the line storage means and the destination number storage means are erased when the communication ends and the telephone goes off-hook to prepare for the next transmission.

FIG. 1 is a block diagram showing an embodiment of the present invention. As shown in the figure, the telephone 1 includes a dial key-2, a line instruction switch 3, an input unit 4, and a destination number storage unit 5.
And a line storage unit 6, a control unit 7, and a transmission unit 8. Dial key-2 inputs a destination telephone number. The line instruction switch 3 indicates whether the outgoing line is an external line or an internal line. The input unit 7 sends the contents input by the dial key-2 and the line instruction switch 3 to the destination number storage unit 5 and the line storage unit 6, respectively, and stores them. The destination number storage means 5 stores the destination telephone number input by the dial key-2. The line storage means 6 stores the line transmitted by the line instruction switch 3. The control unit 7 reads out the contents stored in the destination number storage unit 5 and the line storage unit 6 and sends them to the transmission unit 8. The transmitting section 8 transmits to the private branch exchange 9 in accordance with the transmitted contents.

The operation of the telephone 1 constructed as described above will be described with reference to the flowchart of FIG.

First, dial key-2 and line instruction switch 3
To indicate whether the outgoing line is an outside line or an extension, and store the outgoing line number and the outgoing line in the outgoing number storing means 5 and the line storing means 6, respectively (step S1). ). When the telephone number of the called party is stored in the called party number storing means 5, the control unit 7
It is confirmed whether or not a line to be transmitted is stored (step S2). If the line to be transmitted is not stored, that is, if the line instruction switch 3 is not operated, the operation waits until the line instruction switch 3 is operated with the other party's telephone number stored (step S3). In this state, when the line instruction switch 3 is operated and the line to be transmitted is stored in the line storage means 6, the control unit 7 sets the line storage means 6
Is read out, and a corresponding control signal is sent to the transmission unit 8 to connect to the designated line (step S4). Next, the control unit 7 controls the destination number storage unit 5
And reads out the other party's telephone number and sends it to transmitting section 8 (step S5). Then, when the connection is established, the communication state is entered (steps S6 and S7). If the destination telephone number sent out at this time is busy, it waits for another telephone number to be input (step S8). Then, when the connection is completed and the communication is completed and the telephone goes off-hook, the control unit 7 deletes the contents stored in the destination number storage unit 5 and the line storage unit 6 and prepares for the next transmission (step S9).

As described above, the destination telephone number and the line to be transmitted are stored in the destination number storage means 5 and the line storage means 6, respectively, and the line to be transmitted is read out by the control unit 7 when the line to be transmitted is stored. The line to be transmitted can be specified either before or after inputting the telephone number of the other party, thereby preventing erroneous operation at the time of calling.

[0014]

As described above, according to the present invention, the line to be transmitted and the destination number are stored in the line storage means and the destination number storage means, respectively, so that the transmission can be made before or after inputting the destination number. The line to be connected can be specified, and the operation of selecting an extension and an outside line can be easily performed.

The destination number is stored in the destination number storage means until the line to be transmitted is stored in the line storage means. When the line to be transmitted is stored in the line storage means, the line to be transmitted is first read out and sent out. Since the destination number is read out and sent to the destination after transmission, it is possible to prevent an erroneous operation at the time of calling and to eliminate the necessity of redialing the destination telephone number.

The contents stored in the line storage means and the destination number storage means are erased when the communication is completed and the telephone goes on-hook , so that the next transmission can be prepared.
