Generally, the period during which the PTT switch is pressed is in the transmission state, and when the PTT switch is released, it operates to return to the reception state. In order to maintain the transmission state for a long time, it is necessary to keep pressing the PTT switch. In order to improve user convenience, a function to lock the state in which the PTT switch is pressed is required. For example, the transmission state is maintained when the operation pattern of the PTT switch is a pattern in which the PTT switch is turned on continuously for a predetermined set time or more and then turned on again within a predetermined elapsed time (for example, a patent) Reference 1).

The voice processing unit 18 receives voice from the microphone 16. The audio processing unit 18 performs processing such as encoding on the audio. The voice processing unit 18 outputs the voice (hereinafter also referred to as “voice”) on which the processing has been performed to the transmission unit 20.
　送信部２０は、音声処理部１８からの音声を受けつける。送信部２０は、音声を含めるように音声信号を生成する。送信部２０は、生成した音声信号に対して、制御部１４からの制御に応じて送信処理を実行する。ここでは、制御部１４における制御を説明する。制御部１４は、検出部１２がボタンの押し下げを検出している期間にわたって、音声信号を送信し続けるように送信部２０を制御する。一方、制御部１４は、検出部１２がボタンの押し下げを検出していない期間において、音声信号の送信を停止するように送信部２０を制御する。その結果、送信部２０は、検出部１２がボタンの押し下げを検出している期間にわたって、音声処理部１８からの音声信号を送信し続ける。送信部２０は、検出部１２がボタンの押し下げを検出していない期間において、音声信号の送信を停止する。 The transmission unit 20 receives the voice from the voice processing unit 18. The transmitter 20 generates an audio signal so as to include audio. The transmission unit 20 performs transmission processing on the generated audio signal according to the control from the control unit 14. Here, control in the control unit 14 will be described. The control unit 14 controls the transmission unit 20 to continue transmitting the audio signal during a period in which the detection unit 12 detects that the button is pressed. On the other hand, the control unit 14 controls the transmission unit 20 to stop transmission of the audio signal in a period in which the detection unit 12 does not detect depression of the button. As a result, the transmitting unit 20 continues transmitting the audio signal from the audio processing unit 18 during a period in which the detection unit 12 detects that the button is pressed. The transmission unit 20 stops transmission of the audio signal in a period in which the detection unit 12 does not detect pressing of the button.
　通知部２２は、例えば、ＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）である。通知部２２は、制御部１４によって送信部２０が音声信号を送信し続けるように制御されている場合、赤色に点灯する。一方、通知部２２は、制御部１４によって送信部２０が音声信号の送信を停止するように制御されている場合、消灯する。つまり、通知部２２は、点灯することによって送信状態をユーザに通知する。なお、通知部２２は、ＬＣＤ（Ｌｉｑｕｉｄ　Ｃｒｙｓｔａｌ　Ｄｉｓｐｌａｙ）であってもよい。 The notification unit 22 is, for example, a light emitting diode (LED). The notification unit 22 lights in red when the control unit 14 controls the transmission unit 20 to continue transmitting an audio signal. On the other hand, the notification unit 22 turns off when the control unit 14 controls the transmission unit 20 to stop transmission of the audio signal. That is, the notification unit 22 notifies the user of the transmission state by lighting up. The notification unit 22 may be an LCD (Liquid Crystal Display).
（２）送信保持モード
　ここでは、送信保持モードでの動作を説明するために、図２（ａ）－（ｊ）を使用する。図２（ａ）－（ｊ）は、送信装置１００における動作タイミングを示す。図２（ａ）は、ＰＴＴボタン１０、検出部１２、制御部１４における動作タイミングを示す。ＰＴＴボタン１０には、期間Ｔ１以内の押し下げ、期間Ｔ２以内の非押し下げ、期間Ｔ３以内の押し下げがなされる。その後、ＰＴＴボタン１０は押し下げられない。例えば、期間Ｔ１は３００ｍｓに設定され、期間Ｔ２は２００ｍｓに設定され、期間Ｔ３は３００ｍｓに設定される。これらの期間はこれに限定されない。 (2) Transmission Holding Mode Here, FIGS. 2A to 2J will be used to explain the operation in the transmission holding mode. 2 (a) to 2 (j) show operation timings in the transmission apparatus 100. FIG. FIG. 2A shows operation timings of the PTT button 10, the detection unit 12, and the control unit 14. The PTT button 10 is depressed within the period T1, not depressed within the period T2, and depressed within the period T3. After that, the PTT button 10 can not be depressed. For example, the period T1 is set to 300 ms, the period T2 is set to 200 ms, and the period T3 is set to 300 ms. These periods are not limited to this.
　検出部１２は、期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出し、その後、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出が続き、さらに続いて、期間Ｔ３以内のＰＴＴボタン１０の押し下げを連続して検出する。その後、検出部１２は、ＰＴＴボタン１０の押し下げの非検出が続く。なお、実際には、ＰＴＴボタン１０が押し下げられるタイミングと、検出部１２がＰＴＴボタン１０の押し下げを検出するタイミングはずれているが、ここでは、説明を明瞭にするために、そのずれを無視する。 The detection unit 12 detects the depression of the PTT button 10 within the period T1, and subsequently, the non-detection of the depression of the PTT button 10 within the period T2 continues, and then, the depression of the PTT button 10 within the period T3 is continued To detect. Thereafter, the detection unit 12 continues non-detection of the depression of the PTT button 10. Although the timing at which the PTT button 10 is depressed and the timing at which the detection unit 12 detects the depression of the PTT button 10 are deviated in practice, the deviation is ignored here for the sake of clarity.
　制御部１４は、検出部１２において、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出、期間Ｔ３以内のＰＴＴボタン１０の押し下げの検出が連続した場合、通常送信モードから送信保持モードへの切替を実行する。送信保持モードの場合、制御部１４は、検出部１２においてＰＴＴボタン１０の押し下げを非検出であっても音声信号の送信を継続するように送信部２０を制御する。なお、制御部１４は、検出部１２において期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出した場合、送信保持モードへの切替がなされていなくても、ＰＴＴボタン１０の押し下げが非検出であると、期間Ｔ２以内において音声信号の送信を継続するように送信部２０を制御する。 When the control unit 14 detects that the PTT button 10 is pressed within the period T1, does not detect pressing the PTT button 10 within the period T2, and detects that the PTT button 10 is pressed within the period T3 in the detection unit 12 continuously. , Switching from the normal transmission mode to the transmission holding mode. In the case of the transmission holding mode, the control unit 14 controls the transmission unit 20 to continue the transmission of the audio signal even when the detection unit 12 does not detect the depression of the PTT button 10. If the control unit 14 detects that the PTT button 10 has been pressed within the period T1 in the detection unit 12, it is determined that pressing of the PTT button 10 is not detected even if switching to the transmission holding mode is not performed. The transmission unit 20 is controlled to continue the transmission of the audio signal within the period T2.
　図２（ｂ）は、送信部２０における動作タイミングを示す。送信部２０は、検出部１２において期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出した場合、制御部１４からの制御に応じて音声信号の送信を開始する。これに続いて、ＰＴＴボタン１０の押し下げが非検出であっても、送信部２０は、期間Ｔ２以内において音声信号の送信を継続する。さらに、送信保持モードになると、制御部１４による送信の継続の制御によって、送信部２０は音声信号の送信を継続する。 FIG. 2B shows the operation timing of the transmission unit 20. When the detection unit 12 detects that the PTT button 10 is pressed within the period T1, the transmission unit 20 starts transmission of an audio signal according to the control from the control unit 14. Subsequently, even if the depression of the PTT button 10 is not detected, the transmission unit 20 continues the transmission of the audio signal within the period T2. Furthermore, in the transmission holding mode, the transmission unit 20 continues transmission of the audio signal by control of continuation of transmission by the control unit 14.
　図２（ｃ）は、通知部２２のＬＥＤにおける動作タイミングを示す。図２（ｂ）と比較すると明らかなように、通知部２２のＬＥＤは、送信部２０が音声信号を送信している期間にわたって赤色に点灯し、それ以外の期間において消灯する。図２（ｄ）は、通知部２２のＬＣＤにおける動作タイミングを示す。通知部２２のＬＣＤは、制御部１４において送信保持モードが選択されている期間にわたって、「－Ｈｏｌｄ－」の文字を点灯させる。なお、ＬＣＤにおける表示はこれに限定されない。 FIG. 2C shows the operation timing of the LED of the notification unit 22. As apparent from comparison with FIG. 2B, the LED of the notification unit 22 lights in red during the period in which the transmission unit 20 is transmitting the audio signal, and is turned off in the other periods. FIG. 2D shows the operation timing of the notification unit 22 in the LCD. The LCD of the notification unit 22 lights the characters “-Hold-” for the period in which the transmission holding mode is selected in the control unit 14. The display on the LCD is not limited to this.
　次に、送信保持モードに切りかえられた後の動作を説明する。図２（ａ）に示すように送信保持モードにおいてＰＴＴボタン１０は押し下げられない。その後、ＰＴＴボタン１０が押し下げられ、続いて非押し下げがなされるとともに、押し下げが終了する。検出部１２は、ＰＴＴボタン１０の押し下げの終了を検出する。制御部１４は、送信保持モードである場合に、検出部１２においてＰＴＴボタン１０の押し下げの終了が検出されると、音声信号の送信を停止するように送信部２０を制御する。これは、送信保持モードを通常送信モードに戻すことに相当する。図２（ｂ）に示すように、送信保持モードにおいて、検出部１２がＰＴＴボタン１０の押し下げの終了を検出すると、送信部２０は音声信号の送信を停止する。図２（ｃ）に示すように、送信部２０が音声信号の送信を停止すると、通知部２２のＬＥＤは消灯する。図２（ｄ）に示すように、送信保持モードが通常送信モードに戻されると、通知部２２のＬＣＤは表示を終了する。 Next, an operation after switching to the transmission holding mode will be described. As shown in FIG. 2A, the PTT button 10 is not depressed in the transmission holding mode. Thereafter, the PTT button 10 is depressed, followed by non-depression, and the depression ends. The detection unit 12 detects the end of pressing of the PTT button 10. When the end of depression of the PTT button 10 is detected in the detection unit 12 in the transmission holding mode, the control unit 14 controls the transmission unit 20 to stop transmission of the audio signal. This corresponds to returning the transmission holding mode to the normal transmission mode. As shown in FIG. 2B, in the transmission holding mode, when the detection unit 12 detects the end of pressing of the PTT button 10, the transmission unit 20 stops transmission of the audio signal. As shown in FIG. 2C, when the transmission unit 20 stops the transmission of the audio signal, the LED of the notification unit 22 is turned off. As shown in FIG. 2D, when the transmission holding mode is returned to the normal transmission mode, the LCD of the notification unit 22 ends the display.
　図２（ｅ）－（ｊ）は、通常送信モードから送信保持モードへの切替がなされない場合を説明する。ここでは、（Ａ）第１ケース、（Ｂ）第２ケース、（Ｃ）第３ケースの順に説明する。 FIG. 2 (e)-(j) illustrate the case where the normal transmission mode is not switched to the transmission holding mode. Here, (A) first case, (B) second case, and (C) third case will be described in this order.
（Ａ）第１ケース
　図２（ｅ）は、ＰＴＴボタン１０、検出部１２、制御部１４における動作タイミングを示す。ＰＴＴボタン１０は、期間Ｔ１よりも長い期間にわたって押し下げられる。検出部１２は、期間Ｔ１よりも長い期間にわたるＰＴＴボタン１０の押し下げを検出する。制御部１４は、期間Ｔ１よりも長い期間にわたるＰＴＴボタン１０の押し下げが検出部１２において検出されると、通常送信モードを維持する。図２（ｆ）は、送信部２０における動作タイミングを示す。制御部１４において通常送信モードが維持されるので、送信部２０は、検出部１２が期間Ｔ１より長い期間にわたるＰＴＴボタン１０の押し下げを検出した場合、検出部１２においてＰＴＴボタン１０の押し下げが非検出になると、音声信号の送信を停止する。 (A) First Case FIG. 2E shows the operation timing of the PTT button 10, the detection unit 12, and the control unit 14. The PTT button 10 is depressed for a period longer than the period T1. The detection unit 12 detects the depression of the PTT button 10 for a period longer than the period T1. The control unit 14 maintains the normal transmission mode when the detection unit 12 detects that the PTT button 10 is depressed for a period longer than the period T1. FIG. 2F shows the operation timing of the transmission unit 20. Since the normal transmission mode is maintained in the control unit 14, when the detection unit 12 detects that the PTT button 10 has been pressed for a period longer than the period T1, the transmission unit 20 does not detect that the PTT button 10 is pressed When it becomes, the transmission of the audio signal is stopped.
（Ｂ）第２ケース
　図２（ｇ）は、ＰＴＴボタン１０、検出部１２、制御部１４における動作タイミングを示す。ＰＴＴボタン１０は、期間Ｔ１以内の押し下げ、期間Ｔ２よりも長い期間にわたる非押し下げがなされる。検出部１２は、期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出してから期間Ｔ２より長い期間にわたってＰＴＴボタン１０の押し下げの非検出が続く。制御部１４は、検出部１２において、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出がなされても、期間Ｔ２よりも長い期間にわたってＰＴＴボタン１０の押し下げの非検出が続くので、通常送信モードを維持する。しかしながら、前述のごとく、制御部１４は、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出後、ＰＴＴボタン１０の押し下げが非検出であると、期間Ｔ２以内において音声信号の送信を継続するように送信部２０を制御する。 (B) Second Case FIG. 2G shows operation timings of the PTT button 10, the detection unit 12, and the control unit 14. The PTT button 10 is depressed within the period T1, and is not depressed for a period longer than the period T2. After detecting that the PTT button 10 has been pressed within the period T1, the detection unit 12 continues to detect that the PTT button 10 has not been pressed for a period longer than the period T2. Even when the detection unit 12 detects that the PTT button 10 has been pressed within the period T1, the control unit 14 maintains the normal transmission mode because the non-detection of the PTT button 10 being pressed continues for a period longer than the period T2. Do. However, as described above, when the control unit 14 detects that the PTT button 10 has been pressed within the period T1 but does not detect that the PTT button 10 has been pressed, transmission of the audio signal is continued within the period T2. Control unit 20;
　図２（ｈ）は、送信部２０における動作タイミングを示す。送信部２０は、検出部１２が期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出した場合、期間Ｔ１以内において音声信号を送信する。また、送信部２０は、検出部１２が期間Ｔ２よりも長い期間にわたってＰＴＴボタン１０の押し下げの非検出が続く場合、期間Ｔ２だけにおいて音声信号を送信する。つまり、送信部２０は、検出部１２が期間Ｔ１以内のＰＴＴボタン１０の押し下げを検出してから期間Ｔ２より長い期間にわたるＰＴＴボタン１０の押し下げを非検出である場合、検出部１２においてＰＴＴボタン１０の押し下げが検出となってから期間Ｔ２経過した後に音声信号の送信を停止する。 FIG. 2H shows the operation timing of the transmission unit 20. When the detection unit 12 detects that the PTT button 10 is pressed within the period T1, the transmission unit 20 transmits an audio signal within the period T1. The transmission unit 20 transmits an audio signal only in the period T2 when the detection unit 12 continues to detect that the PTT button 10 is not pressed down for a period longer than the period T2. That is, when the detection unit 12 detects no depression of the PTT button 10 for a period longer than the period T2 after the detection unit 12 detects the depression of the PTT button 10 within the period T1, the transmission unit 20 detects the PTT button 10 in the detection unit 12. The transmission of the audio signal is stopped after the period T2 has elapsed since the detection of the depression of the switch.
（Ｃ）第３ケース
　図２（ｉ）は、ＰＴＴボタン１０、検出部１２、制御部１４における動作タイミングを示す。ＰＴＴボタン１０には、期間Ｔ１以内の押し下げ、期間Ｔ２以内の非押し下げ、期間Ｔ３より長い期間の押し下げがなされる。検出部１２は、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出、それに続いて、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出、さらに、期間Ｔ３より長い期間のＰＴＴボタン１０の押し下げの検出が連続してなされる。 (C) Third Case FIG. 2I shows operation timings of the PTT button 10, the detection unit 12, and the control unit 14. The PTT button 10 is depressed within the period T1, not depressed within the period T2, and depressed for a period longer than the period T3. The detection unit 12 detects that the PTT button 10 has been pressed within the period T1, followed by non-detection of pressing the PTT button 10 within the period T2, and further detects that the PTT button 10 has been pressed for a period longer than the period T3. It is made continuously.
　制御部１４は、検出部１２において、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出、期間Ｔ３より長い期間のＰＴＴボタン１０の押し下げの検出が連続した場合、通常送信モードを維持する。この場合、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出までは、送信保持モードに切りかえるための押し下げパターンに一致するので、制御部１４は期間Ｔ２以内において音声信号の送信を継続するように送信部２０を制御する。 The control unit 14 detects that the PTT button 10 is depressed within the period T1, does not detect depression of the PTT button 10 within the period T2, and detects that the PTT button 10 is depressed for a period longer than the period T3 in the detection unit 12 continuously. If so, the normal transmission mode is maintained. In this case, the control unit 14 detects the depression of the PTT button 10 within the period T1 and the non-detection of the depression of the PTT button 10 within the period T2 according to the depression pattern for switching to the transmission holding mode. The transmission unit 20 is controlled to continue the transmission of the audio signal within the range.
　図２（ｊ）は、送信部２０における動作タイミングを示す。送信部２０は、制御部１４において通常送信モードが維持される。そのため、送信部２０は、検出部１２において、期間Ｔ１以内のＰＴＴボタン１０の押し下げの検出、期間Ｔ２以内のＰＴＴボタン１０の押し下げの非検出、期間Ｔ３より長い期間のＰＴＴボタン１０の押し下げの検出が連続した場合、音声信号を送信する。その後、検出部１２においてＰＴＴボタン１０の押し下げが検出されなければ、送信部２０は音声信号の送信を停止する。 FIG. 2 (j) shows the operation timing of the transmission unit 20. In the transmission unit 20, the control unit 14 maintains the normal transmission mode. Therefore, in the detection unit 12, the transmission unit 20 detects that the PTT button 10 is pressed within the period T1, does not detect that the PTT button 10 is pressed within the period T2, and detects that the PTT button 10 is pressed for a period longer than the period T3. Sends a voice signal. Thereafter, if the detection unit 12 does not detect that the PTT button 10 is pressed, the transmission unit 20 stops the transmission of the audio signal.
　この構成は、ハードウエア的には、任意のコンピュータのＣＰＵ、メモリ、その他のＬＳＩで実現でき、ソフトウエア的にはメモリにロードされたプログラムなどによって実現されるが、ここではそれらの連携によって実現される機能ブロックを描いている。したがって、これらの機能ブロックがハードウエアのみ、ハードウエアとソフトウエアの組合せによっていろいろな形で実現できることは、当業者には理解されるところである。 In terms of hardware, this configuration can be realized with the CPU, memory, or other LSI of any computer, and with software, it can be realized by a program loaded into the memory, etc. Are drawing functional blocks. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms only by hardware and by a combination of hardware and software.
　以上の構成による送信装置１００の動作を説明する。図３は、送信装置１００による送信手順を示すフローチャートである。送信装置１００は待ち受け状態になっている（Ｓ１０）。検出部１２が押し下げを検出しなければ（Ｓ１２のＮ）、待機する。検出部１２が押し下げを検出すれば（Ｓ１２のＹ）、検出部１２は押し下げ検出期間の計測を開始する（Ｓ１４）。送信部２０は音声信号の送信を開始する（Ｓ１６）。検出部１２が押し下げを非検出でなければ（Ｓ１８のＮ）、待機する。検出部１２が押し下げを検出せず（Ｓ１８のＹ）、押し下げ検出期間が３００ｍｓ以内でなければ（Ｓ２０のＮ）、処理は終了される。押し下げ検出期間が３００ｍｓ以内であれば（Ｓ２０のＹ）、検出部１２は押し下げ非検出期間の計測を開始する（Ｓ２２）。押し下げ非検出期間が２００ｍｓを経過すれば（Ｓ２４のＹ）、送信部２０は音声信号の送信を終了する（Ｓ４２）。 The operation of the transmitting apparatus 100 having the above configuration will be described. FIG. 3 is a flowchart showing a transmission procedure by the transmission device 100. The transmission device 100 is in the standby state (S10). If the detection unit 12 does not detect the depression (N at S12), the process waits. When the detection unit 12 detects a depression (Y in S12), the detection unit 12 starts measurement of a depression detection period (S14). The transmitter 20 starts transmission of the audio signal (S16). If the detection unit 12 does not detect depression (N in S18), the process waits. If the detection unit 12 does not detect depression (Y at S18) and the depression detection period is not within 300 ms (N at S20), the process is terminated. If the depression detection period is within 300 ms (Y in S20), the detection unit 12 starts measurement of the depression non-detection period (S22). When the depression non-detection period passes 200 ms (Y in S24), the transmission unit 20 ends the transmission of the audio signal (S42).
　押し下げ非検出期間が２００ｍｓを経過せず（Ｓ２４のＮ）、検出部１２が押し下げを検出しなければ（Ｓ２６のＮ）、ステップ２４に戻る。検出部１２が押し下げを検出すれば（Ｓ２６のＹ）、検出部１２は押し下げ検出期間の計測を開始する（Ｓ２８）。押し下げ検出期間が３００ｍｓを経過すれば（Ｓ３０のＹ）、制御部１４は、通常送信モードを決定する（Ｓ３８）。検出部１２が押し下げを非検出でなければ（Ｓ４０のＮ）、待機する。検出部１２が押し下げを非検出であれば（Ｓ４０のＹ）、送信部２０は音声信号の送信を終了する（Ｓ４２）。 If the depression non-detection period has not passed 200 ms (N in S24) and the detection unit 12 does not detect depression (N in S26), the process returns to step S24. If the detection unit 12 detects a depression (Y in S26), the detection unit 12 starts measurement of a depression detection period (S28). When the depression detection period passes 300 ms (Y in S30), the control unit 14 determines the normal transmission mode (S38). If the detection unit 12 does not detect depression (N in S40), the process waits. If the detection unit 12 does not detect depression (Y at S40), the transmission unit 20 ends the transmission of the audio signal (S42).
　押し下げ検出期間が３００ｍｓを経過せず（Ｓ３０のＮ）、検出部１２が押し下げを非検出でなければ（Ｓ３２のＮ）、ステップ３０に戻る。検出部１２が押し下げを非検出であれば（Ｓ３２のＹ）、制御部１４は、送信保持モードを決定する（Ｓ３４）。検出部１２が押し下げ終了を検出しなければ（Ｓ３６のＮ）、待機する。検出部１２が押し下げ終了を検出すれば（Ｓ３６のＹ）、制御部１４は、通常送信モードを決定する（Ｓ３８）。検出部１２が押し下げを非検出でなければ（Ｓ４０のＮ）、待機する。検出部１２が押し下げを非検出であれば（Ｓ４０のＹ）、送信部２０は音声信号の送信を終了する（Ｓ４２）。 If the depression detection period does not pass 300 ms (N in S30) and the detection unit 12 does not detect depression (N in S32), the process returns to step S30. If the detection unit 12 does not detect depression (Y at S32), the control unit 14 determines the transmission holding mode (S34). If the detection unit 12 does not detect the end of the depression (N at S36), the process waits. When the detection unit 12 detects the end of the depression (Y in S36), the control unit 14 determines the normal transmission mode (S38). If the detection unit 12 does not detect depression (N in S40), the process waits. If the detection unit 12 does not detect depression (Y at S40), the transmission unit 20 ends the transmission of the audio signal (S42).
　本実施例によれば、期間Ｔ１以内の押し下げの検出、期間Ｔ２以内の押し下げの非検出、期間Ｔ３以内の押し下げの検出が連続した場合、押し下げを非検出であっても音声信号を送信し続けるので、簡易な操作で送信状態を維持できる。また、キー操作時間が短く、かつよりシンプルな２回押しを操作パターンにするので、ロック完了のために送信装置を確認することを不要にできる。また、ロック完了までの不要な信号の送信時間を短縮できる。また、通常送信モードで音声信号を送信した場合に操作パターンから外れるので、改めて操作パターンの操作を行わない限りロックを回避できる。また、改めて操作パターンの操作を行わない限りロックが回避されるので、通常の通話の後に、続けて通話を行う際も意図しないロックが発生することを回避できる。 According to the present embodiment, when detection of depression within period T1, detection of depression within period T2 is not detected, and detection of depression within period T3 continue, the voice signal continues to be transmitted even if depression is not detected. Therefore, the transmission state can be maintained by a simple operation. In addition, since the key operation time is short and the simpler double pressing is used as the operation pattern, it is not necessary to check the transmitting device for the lock completion. Moreover, the transmission time of the unnecessary signal until lock completion can be shortened. In addition, since the voice signal is transmitted in the normal transmission mode, it deviates from the operation pattern, so locking can be avoided unless another operation pattern operation is performed. In addition, since the lock is avoided unless the operation pattern is operated again, it is possible to prevent the occurrence of an unintended lock even when making a call after a normal call.
　また、押し下げを非検出であっても音声信号を送信し続けている場合に、押し下げの終了を検出すると、音声信号の送信を停止するので、送信保持モードを終了できる。また、期間Ｔ１より長い期間にわたる押し下げを検出した場合に通常送信モードを維持するので、送信保持モードへの切替を回避できる。また、期間Ｔ１以内の押し下げを検出してから期間Ｔ２より長い期間にわたる押し下げを非検出である場合に通常送信モードを維持するので、送信保持モードへの切替を回避できる。また、期間Ｔ１以内の押し下げの検出と期間Ｔ２以内の押し下げの非検出に続いて期間Ｔ３より長い期間にわたる押し下げが検出された場合に通常送信モードを維持するので、送信保持モードへの切替を回避できる。 In addition, even if the depression is not detected, when the voice signal continues to be transmitted, when the end of the depression is detected, the transmission of the audio signal is stopped, so that the transmission holding mode can be ended. In addition, since the normal transmission mode is maintained when the depression for a period longer than the period T1 is detected, the switching to the transmission holding mode can be avoided. Further, since the normal transmission mode is maintained when the depression within the period T1 is not detected after the depression within the period T1 is detected, the switching to the transmission holding mode can be avoided. In addition, since the normal transmission mode is maintained when the depression for a period longer than period T3 is detected following the detection of the depression within period T1 and the non-detection of the depression within period T2, switching to the transmission holding mode is avoided. it can.
