Abstract

PURPOSE:To prevent dial information requiring security of secrecy from being left in the speech recording by providing a recording control means deleting information relating to a dialed number by an extension telephone set from the speech recording to the speech recorder when a prescribed signal is received by an information transmission means. CONSTITUTION:When a user depresses a dial information delete button 3 of a telephone set 21, the telephone set 21 outputs a prescribed signal and when a CPU circuit 5 receives it via a telephone set interface circuit 4, a prescribed control signal is outputted to a speech recorder 8. In this case, the CPU circuit 5 acts like an information transmission means outputting a signal representing the depression of the dial information delete button 3. When an edit section 10 receives the control signal through a data reception section 9, it acts like a recording control means to delete dial information from the speech recording. Thus, when the user of the telephone set applies a prescribed operation, the dial information is deleted from the speech recording.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a button telephone device, and in particular, a device for recording calls by outputting information such as call/receive time, call duration, dial number, etc. of an extension telephone to a printer or the like. The present invention relates to a button telephone device that can be used.

[Conventional technology]

Conventionally, this type of key telephone device is equipped with a call recording device connected to an external recording device such as a printer, and information such as call/receive time, call duration, dialed number, etc. of the extension telephone is stored as a call record in the external device. It is now possible to record.

[Problem to be solved by the invention]

However, with conventional key telephone devices, all dial information dialed by the telephone user is left as a call record, so dial information that must be kept secret (for example, credit card call PIN, computer access code, etc.)
Call records are also kept, which poses a problem in terms of confidentiality.

SUMMARY OF THE INVENTION An object of the present invention is to solve such problems and provide a button telephone device that can delete dial information from a call record when a user of the telephone performs a predetermined operation.

[Means to solve the problem]

The present invention provides a button telephone device that accommodates at least one outside line and a plurality of extension telephones and is equipped with a call recording device that records at least numbers dialed on the extension telephone as a call record. The call recording device includes a dial information deletion button and information transmission means that outputs a predetermined signal to the call recording device when this button is operated, and the call recording device outputs an extension when the predetermined signal is received from the information transmission means. The present invention is characterized by comprising a record control means for deleting information regarding a number dialed by a telephone from a call record.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of a key telephone device according to the present invention. This device includes a main device 1 connected to a plurality of outside lines, and a plurality of extension telephones 21 to 1 connected to the main device 1.
2m, a call recording device 8, and a printer 12 connected to the call recording device 8.

Each of the extension telephones 21 to 2m is equipped with a dial information deletion button 3, and when this button is pressed, the telephone outputs a predetermined signal to the main device l.

The main device 1 is composed of a telephone interface circuit 4, a CPU circuit 5, an outside line interface circuit 6, and a switch matrix 7.

The telephone interface circuit 4 connects the telephones 21 to 2m and the switch matrix 7, and the telephones 21 to 2m and the CPU.
The external line interface circuit 6 functions as an interface between the external line and the switch matrix 7.
, and functions as an interface between the external line and the CPU circuit 5. Switch matrix 7 is CPU circuit 5
A communication path connecting the telephone and an outside line is formed based on the control of the telephone.

The CPU circuit 5 operates based on a predetermined program,
It controls the telephone interface circuit 4, the outside line interface circuit 6, the switch matrix 7, and the call recorder 8.

The call recording device 8 includes a data receiving section 9, an editing section 10, and a printer interface circuit 11. The data receiving section 9 receives data and control signals from the CPU circuit 5 and sends them to the editing section 10. Editorial department 1
0 edits the call record based on these data and control signals, and sends the result to the printer interface circuit 1.
1 to the printer 12 for printing.

Next, as an example, the operation when a call is made from the telephone 21 and the dial information is deleted from the call record will be described. When the user goes off-hook with the telephone 21 and presses a line button (not shown), the information is sent to the CPU circuit 5 through the telephone interface circuit 4. The CPU circuit 5 thereby controls the switch matrix 7 to form a communication path between the corresponding line and the telephone 21, and at the same time records the line number captured in the call recorder, the number of the telephone that made the call, and makes the call. Sends information regarding time.

Next, when the user dials on the telephone 21, the information is sent to the same CPU circuit 5, which controls the outside line interface circuit 6 to send a dial signal to the line, and at the same time sends the dial information to the call recorder 8. send.

In the call recording device 8, the data receiving section 9 receives the above information from the CPU circuit 5 and provides it to the editing section 10.
0 edits the call record based on the information received and starts counting the call time.

When the user presses the dial information deletion button on the telephone 21, the telephone 21 outputs a predetermined signal and the CPU
When the circuit 5 receives this through the telephone interface circuit 4, it outputs a predetermined control signal to the call recorder 8. At this time, the CPU circuit 5 operates as an information transmitting means that outputs a signal indicating that the dial information deletion button has been pressed. When the editing section 10 receives this control signal through the data receiving section 9, it operates as a recording control means and deletes the dial information from the call record being edited.

When the call ends, the CPU circuit 5 restores the outside line interface circuit 6 and the switch matrix 7, while
The call recorder 8 is notified of the end of the call. As a result, the editing department 10 finishes measuring the call time and editing the call record,
The printer interface circuit 11 outputs data regarding the line number, the telephone number that made the call, the time of the call, and the duration of the call to the printer to print the call record. Since the dial information is deleted at the time of editing as described above, it is not included in the printed call record.

〔Effect of the invention〕

As explained above, in the button telephone device of the present invention, which accommodates at least one external line and a plurality of extension telephones, and is equipped with a call recording device that records at least the numbers dialed on the extension telephone as a call record, each extension telephone The telephone includes a dial information deletion button provided on the telephone, and information transmission means that outputs a predetermined signal to the call recording device when the button is operated, and the call recording device receives the predetermined signal from the information transmission means. A recording control means is provided for deleting information regarding a number dialed by an extension telephone from a call record.

Therefore, according to the present invention, it is possible to realize a button telephone device in which dial information is deleted from the call record when the user of the telephone performs a predetermined operation on the dial information deletion button. As a result, dial information that needs to be kept confidential, such as credit card call numbers and computer access codes, can be prevented from remaining in the call record, and leakage thereof can be prevented.
