Abstract

PURPOSE:To eliminate sudden speech interruption due to malfunction during talking by applying control to the telephone set to interrupt a telephone line after lapse of a prescribed time when a hook button is in operation during talking. CONSTITUTION:When a hook button 8 is operated due to any cause, it is detected by a hook button detection section 62 and a detection signal is given to a hook switch circuit control section 64. The control section 64 starts a timer 65 with the detection signal and when the count for a prescribed time is finished, the count end signal is sent. The control section 64 uses the count end signal to control a hook switch circuit 3, which is interrupted, thereby opening the connection between a speech circuit 4 and a telephone line. The user takes proper processing till the connection of the telephone line is actually interrupted after an erroneous operation of on-hook.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a multi-function telephone, and more specifically, it prevents a telephone line from being suddenly disconnected due to an inadvertent switch operation during a call. Regarding multi-function telephones.

(Prior technology) Many multi-function telephones are equipped with many functions such as a hold function, a clock adjustment (time setting) function, a dial memory function, and a tape recording/playback function, which can be operated during a call. include.

(Problem to be solved by the invention) By the way, there is no problem with this kind of function if it is operated correctly during a call, but since there are many switches, if you operate it slightly incorrectly, the phone may turn off. It may suddenly turn off. As a result, there has been a problem in that the person on the other end of the call feels uncomfortable.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a multifunctional telephone that will not suddenly disconnect the line even if a line disconnection operation is mistakenly performed during a call.

(Means for Solving the Problems) In order to solve the above problems, the multi-function telephone of the present invention includes an on-footer detection section that detects an on-footer operation performed during a call, and an on-footer operation that is detected by the on-footer detection section. a counting section that starts counting a predetermined time when the counting section finishes counting the predetermined time; and a control section that operates a hook switch circuit to disconnect the telephone line when the counting section finishes counting the predetermined time. The structure shall be equipped with the following.

(Function) If an on-footer operation is mistakenly performed during a call, this on-footer operation is detected by the on-footer detection section. By detecting this on-hook operation, the on-footer detection section sends an activation signal to the counting section to activate the counting section. The counting section starts counting a predetermined period of time, and when the counting ends, sends a count end signal to the control section. Upon receiving this count end signal, the control section operates the hook switch circuit to perform control to disconnect the telephone line. In other words, even if the on-footer operation is performed by mistake during a call, the control section does not immediately turn off the hook switch circuit, but the counter section counts a predetermined time and then turns off the hook switch circuit. It looks like this. This allows you to accidentally perform an on-hook operation and then
The user can take appropriate actions before the telephone line is actually disconnected (ie, opened).

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the electrical configuration of a multifunction telephone according to the present invention. However, the drawing only shows the configuration of the portion related to the present invention.

In the figure, reference numeral 1 denotes a connection section including a tip and a ring, which is connected to a telephone line, although not shown. A bridge rectifier circuit 2 is connected to the connecting portion 1, and a hook switch circuit 3 for electrically connecting the telephone to a telephone line is connected to the bridge rectifier circuit 2. In addition, the hook switch circuit 3 includes two wires -4
A communication circuit 4 that performs line conversion and level adjustment of transmitting signals and receiving signals is connected to the communication circuit 4, and a handset 5 equipped with a transmitter and a receiver is connected to the communication circuit 4. The hook switch circuit 3 is configured to also send out a pulse dial signal.

A control circuit 6 consisting of a CPU that controls the operation of the entire telephone includes an operation button reading section 61 and a hook button detection section 62.
, a pulse dial sending unit 63, a hook switch circuit control unit 64, a timer (counting unit) 65, and a telephone call circuit control unit 66.

The output of the operation button section 7 equipped with a numeric keypad and other function buttons is led to an operation button reading section 61, and the output of the operation button reading section 61 is sent to a pulse dial sending section 63 and a communication circuit. The control section 66 leads to the control section 66.

In addition, the output of the hook button 8 is detected by the hook button detection unit 6.
2, and the output of the hook button detection section 62 is
It is led to a hook switch circuit control section 64. The hook switch circuit control section 64 includes a hook button detection section 62.
In addition to the output of the pulse dial transmitter 63, the hook switch circuit controller 64 and the timer 65 are connected bidirectionally. The output of the hook switch circuit control section 64 is guided to the control terminal of the hook switch circuit 3, and the output of the communication circuit control section 66 is guided to the communication circuit 4.

Next, the operation of the multifunction telephone with the above configuration will be explained.

During a call, the connection unit 1 is connected to the telephone line, and the hook switch circuit 3 is in a state where the telephone line and the communication circuit 4 are connected under control from the hook switch circuit control unit 64.

In such a call state, when the hook button 8 is activated for some reason (including when it is operated to end the call), this operating state is detected by the hook button detection section 62, and the detection signal is sent to the hook switch circuit. Control unit 6
given to 4. In the hook switch circuit control section 64,
This detection signal activates the timer 65 to start counting a predetermined time. When the timer 65 finishes counting the predetermined time, the hook switch circuit controller 6
A count end signal is sent to 4.

The hook switch circuit control section 64 controls the hook switch circuit 3 based on this count end signal to turn off the hook switch circuit 3 and disconnect the communication circuit 4 from the telephone line.

As described above, even if the hook button 8 is activated for some reason during a call, the multi-function telephone of the present invention does not disconnect the telephone line immediately, but waits for the predetermined time set in the timer 65 to terminate the call. Since the line is disconnected, it is possible to prevent the occurrence of an inadvertent call termination situation.

In the above embodiment, if the hook button 8 is operated during a call, the telephone line is disconnected after a predetermined period of time has elapsed. It is possible to configure the hook button 8 so that the operation of the hook button 8 can be canceled by operating, for example, a cancel button provided on the button section 7. In this way, even if the hook button 8 is operated inadvertently, the call can be continued without interruption by pressing the cancel button before the telephone line is disconnected. .

(Effects of the Invention) The multifunction telephone of the present invention is configured to disconnect the telephone line after a predetermined period of time if the hook button is activated during a call, so the hook button may be activated by mistake during a call. This eliminates problems such as calls being suddenly cut off, and it also eliminates the need to feel awkward towards the person on the other end of the call.
