Abstract

PURPOSE:To allow the telephone set to cope with the state of an opposite party leaving the handset hook-off by holding a channel switch into the closing state till a prescribed elapses by the count of a count means so as to allow the telephone set to be able to be in a talking state. CONSTITUTION:With a hook switch 8 opened, a CPU 72 detects it and uses a timer 78 to apply time count thereby detecting whether or not a delay time is reached. Moreover, the CPU 72 controls a speech network 5 via an output port 77 to connect a line 1 and a speaker 4 via a network 5. As a result, if 'hallow' is uttered because of the interrupt of talking by an opposite party, voice is sounded from the speaker 4. The CPU 72 detects whether or not the switch 8 is closed (off-hook) via an input port 75 and the preceding operation continues when not in off-hook. On the other hand, when the off-hook is detected, the network 5 is controlled via an output port 77 to connect the line 1 and a handset 3 thereby restarting the conversation.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a telephone set that can open a communication path after confirming that the other party has completely stopped talking. .

(Prior art) A conventional telephone is connected to a telephone as shown in FIG. 6 indicates an incoming call detection circuit, and when a call signal arrives, it notifies the control unit 7 of the incoming call.The control unit 7 is configured as a microcomputer, and is connected to a CPU 72 and a main memory via a bus 71. 73, input port 74. 75,
Output ports 76 and 77 are connected. A notification of an incoming call is received through the input port 74, and off-hook/on-hook information of the hook switch 8 based on the raising and lowering of the handset 3 is received through the input port 75. Opening and closing of the communication path switch 2 is performed via the output port 76, and switching between the handset 3 and the speaker 4 is performed via the output port 17 to the speech network 5.

In the conventional telephone configured in this way, the hook switch 8 closes and opens in response to the lifting and lowering of the handset 3, and the CPU 72 detects this via the input port 75, and the CPU 72 then outputs the signal via the output port 76. The communication path switch 2 is closed and opened.

Therefore, when the handset 3 is taken down from the talking state, the hook switch 8 opens, and the CPU 72 detecting this opens the communication path switch 2 immediately via the output port 76. For this reason, there is a problem in that the other party temporarily stops talking, but when the other party tries to say something that they forgot to mention, the communication path has already been closed and the conversation cannot be made.

(Problem to be solved by the invention) As described above, with conventional telephones, when the handset is taken down from a conversation state, the communication path is immediately closed, and the person on the other end temporarily stops speaking, but the person on the other end forgets to speak. There was a problem that even if I tried to talk, I couldn't make a call.

The present invention was made to solve these problems with conventional telephones, and its purpose is to prevent the communication path from being closed for a while even when the phone is on-hook from a call state.
Therefore, it is an object of the present invention to provide a telephone that allows a person to talk to the other party again.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes: a communication path switch that opens and closes a communication path; a hook detection means that detects off-hook/on-hook; a timer; and a communication switch that detects a communication state. If on-hook is detected by the hook detecting means after the call state is detected by the call state detecting means and the call state detecting means, the on-hook state is detected by the call state detecting means until the predetermined time is counted by the clocking means. The telephone set is equipped with a call control means for keeping the call path switch in a closed state.

(Function) According to the above structure, the communication path switch is held in a closed state until a predetermined time has elapsed as determined by the clocking means, so that communication is possible, so that when the user goes off-hook, he or she can communicate with the other party.

{Example} An example of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, the same precepts in Figure 3 are given the same symbols,
The explanation will be omitted.

In this embodiment, the bus 71 includes a timer 78 and an input port 7.
9 is connected. The switch 9 connected to the input port 79 is used to set the delayed on-hook mode. When this switch 9 is operated, the above mode is set and the corresponding LED lights up. When the switch 9 is operated again, the mode is canceled and the above mode is set at the same time. The LED turns off. In the above mode, the CPU
Reference numeral 72 performs call control according to a program in the flowchart shown in FIG. 2 in the main memory 73. Note that the delay time in delayed on-hook mode is determined by, for example, after operating a specific key (# key, etc.) of the dial keys (not shown) while on-hook.
Operate r1, r2, etc. using the numeric keypad, and in this case, assume that 12 seconds is set. The delay time data set here is stored in the main memory 73 and used.

Next, call control in the delayed on-hook mode will be explained with reference to FIG. When a call is received or a call is made, the hook switch 8 is closed and the communication path switch 2 is closed, and a call is being made. When the conversation ends, the handset 3 of the telephone is put down, and the hook switch 8 is closed. When it becomes open, the CPU 72 detects this (8201).

Therefore, the timer 78 is used to count the time (S2
02). Next, it is detected whether the delay time set as described above has been reached (S203). Further, the CPU 72 controls the speech network 5 via the output port 77, and connects the line 1 and the speaker 4 via the speech network 5 (S204). As a result, the other party forgets to speak, so when the other party utters "moshi, mo", the voice will be heard from the speaker with 4 speakers. CPU 72 is input port 7
5, the hook switch 8 is closed and thus off-hook is detected (S205), and if it is not off-hook, the process returns to step S202 to continue the operation. On the other hand, when off-hook is detected, the speech network 5 is controlled via the output port γI, the line 1 and the handset 3 are connected, and the conversation is resumed (3206). Further, if the off-hook does not occur even after a predetermined period of time has elapsed after on-hook (S201), the call switch 2 is opened and the line path is disconnected (S207).

[Effects of the Invention] As explained above, according to the present invention, the communication path switch is kept closed until a predetermined time has elapsed as determined by the timer, so that during this time, the communication can be resumed and the other party cannot speak. You can respond when you forget and remain off the hook.
