Description

双方向のシリアル通信と単方向の信号受信とを別々の場面で行うカラオケアンプ等の電子機器に関する。   The present invention relates to an electronic device such as a karaoke amplifier that performs bidirectional serial communication and unidirectional signal reception in different scenes.

カラオケアンプは、その設置時に設置場所の広さ等の条件に合わせたボリューム、イコライザ、エコー等の音づくりの設定作業（インストール）が行われる。インストールは、効率的な作業が可能なノートパソコンを介して行われる。すなわち、カラオケアンプにシリアルインタフェースを介してノートパソコンを接続し、ノートパソコンで設定ソフトを起動してインストールを行う。このため、従来のカラオケアンプには、図１に示すように、シリアル通信用のＲＳ２３２Ｃ等のシリアルコネクタ１２０が設けられていた（非特 文献１参照）。   The karaoke amplifier is set up (installed) for sound production such as volume, equalizer, echo, etc. according to the conditions such as the size of the installation location. The installation is performed through a notebook computer capable of efficient work. That is, a notebook computer is connected to the karaoke amplifier via a serial interface, and setting software is activated on the notebook computer for installation. For this reason, the conventional karaoke amplifier is provided with a serial connector 120 such as RS232C for serial communication as shown in FIG. 1 (see Non-Patent Document 1).

また、カラオケアンプには、選曲用リモコンからの赤外線信号を受信するためのリモコン受信ユニットが接続される。大きい部屋では２台のリモコン受信ユニットが設置される場合があるため、従来のカラオケアンプは、リモコン受信ユニットを２台接続可能なように、２つのリモコン受信ユニット接続用のコネクタ１２１，１２２が設けられていた。   The karaoke amplifier is connected to a remote control receiving unit for receiving an infrared signal from the music selection remote controller. Since two remote control receiving units may be installed in a large room, the conventional karaoke amplifier is provided with two remote control receiving unit connection connectors 121 and 122 so that two remote control receiving units can be connected. It was done.

このため、カラオケアンプの背面は図１に示すように３つのコネクタ１２０，１２１，１２２が配列される構成になっていた。   For this reason, the rear surface of the karaoke amplifier has a structure in which three connectors 120, 121, 122 are arranged as shown in FIG.

さらに、上記のように、±１２Ｖで信号を送受信するＲＳ２３２Ｃコネクタを有しているため、図２に示すように、カラオケアンプに内蔵されている５ＶのＴＴＬ回路との電圧レベルを変換する電圧レベル変換回路１１１を内蔵する必要があった。   Furthermore, as described above, since it has an RS232C connector that transmits and receives signals at ± 12V, as shown in FIG. 2, the voltage level for converting the voltage level with the 5V TTL circuit built in the karaoke amplifier It was necessary to incorporate the conversion circuit 111.

設置時のインストール作業が終了すると、設定用のノートパソコンは取り外されるため、シリアル通信用のコネクタは不要になる。また、インストール時には、リモコン信号を受信するためのリモコン受信ユニットは不要である。   When the installation work at the time of installation is completed, the setting notebook personal computer is removed, so the connector for serial communication becomes unnecessary. Further, at the time of installation, a remote control receiving unit for receiving a remote control signal is not necessary.

にもかかわらず、従来のカラオケアンプでは、図１に示すように、シリアル通信用のコネクタとリモコン信号受信用のコネクタを併置していたため、コネクタ用のスペースが多く必要となり背面パネルの広い範囲を占有していた。また、部品点数が多くなりコストアップにつながっていた。   Nevertheless, in the conventional karaoke amplifier, as shown in FIG. 1, since the connector for serial communication and the connector for receiving the remote control signal are juxtaposed, a lot of space for the connector is required and a wide range of the rear panel is required. Occupied. In addition, the number of parts increased, leading to an increase in cost.

以上はカラオケアンプについて説明したが、インストール時に必要なコネクタと通常運用時に必要なコネクタが異なる機器について共通の問題点である。   The karaoke amplifier has been described above, but it is a common problem for devices in which connectors required for installation and connectors required for normal operation are different.

この発明は、双方向のシリアル通信と単方向の信号受信とを別々の場面で行う電子機器において、シリアル通信コネクタと信号受信用コネクタを共用した電子機器を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device that shares a serial communication connector and a signal receiving connector in an electronic device that performs bidirectional serial communication and unidirectional signal reception in different scenes.

請求項１の発明は、シリアル通信用の受信端子、送信端子および第１、第２の信号受信用端子を有し、シリアル通信動作および信号受信動作を実行する制御部と、第１、第２の信号端子を有する外部機器接続用のコネクタと、を備え、前記第１の信号端子に前記受信端子および前記第１の信号受信用端子を接続するとともに、前記第２の信号端子に前記送信端子および前記第２の信号受信用端子を接続したことを特徴とする。   A first aspect of the present invention is a controller having a serial communication receiving terminal, a transmitting terminal, and first and second signal receiving terminals, and executing a serial communication operation and a signal receiving operation; A connector for connecting to an external device having a signal terminal, and connecting the reception terminal and the first signal reception terminal to the first signal terminal, and the transmission terminal to the second signal terminal And the second signal receiving terminal is connected.

請求項２の発明は、前記制御部は、前記シリアル通信用の受信端子に信号が入力され とき前記シリアル通信動作を実行し、前記第１、第２の信号受信用端子に信号が入力されたとき信号受信動作を実行することを特徴とする。   According to a second aspect of the present invention, the control unit executes the serial communication operation when a signal is input to the serial communication receiving terminal, and the signal is input to the first and second signal receiving terminals. And a signal receiving operation is executed.

この発明によれば、シリアル通信と単方向の信号受信とを同時に行わない装置の場合、シリアル通信を行う場面ではコネクタにシリアル通信機器を接続し、単方向の信号受信を行う場面ではコネクタに信号出力装置を接続することにより、コネクタ数を節約することができる。   According to the present invention, in the case of a device that does not perform serial communication and unidirectional signal reception at the same time, a serial communication device is connected to the connector when performing serial communication, and a signal is transmitted to the connector when performing unidirectional signal reception. By connecting the output device, the number of connectors can be saved.

図３はこの発明の実施形態であるカラオケアンプの端子接続の態様を示すブロック図、図４は同カラオケアンプの裏面パネルの一部構成を示す図である。   FIG. 3 is a block diagram showing a terminal connection mode of a karaoke amplifier according to an embodiment of the present invention, and FIG. 4 is a diagram showing a partial configuration of a back panel of the karaoke amplifier.

図３に示すように、カラオケアンプ１は、制御部であるＣＰＵ１０を備えている。ＣＰＵ１０には、信号入出力端子としてＲｅｍｏｔｅ０，Ｒｅｍｏｔｅ１，Ｒｘ，Ｔｘが設けられている。端子Ｒｅｍｏｔｅ０，Ｒｅｍｏｔｅ１は、カラオケアンプ１に外部接続されるリモコン受光ユニット３、４が受信したリモコン信号を入力するための端子である。端子Ｒｘ，Ｔｘは、カラオケアンプ１の動作設定用のノートパソコン２とシリアル通信するための受信端子Ｒｘ，送信端子Ｔｘである。   As shown in FIG. 3, the karaoke amplifier 1 includes a CPU 10 that is a control unit. The CPU 10 is provided with Remote 0, Remote 1, Rx, and Tx as signal input / output terminals. Terminals Remote 0 and Remote 1 are terminals for inputting remote control signals received by the remote control light receiving units 3 and 4 externally connected to the karaoke amplifier 1. Terminals Rx and Tx are a reception terminal Rx and a transmission terminal Tx for serial communication with the notebook personal computer 2 for operation setting of the karaoke amplifier 1.

一方、図４に示すように、カラオケアンプ１は、筐体の背面に１つのコネクタ１２を有している。コネクタ１２は、４端子のミニＤＩＮコネクタである。図３では、４つの端子を、１２Ａ，１２Ｂ，１２Ｈ，１２Ｇと呼ぶ。端子１２Ａ，Ｂは信号用の端子である。端子１２Ｈは電源用の端子であり、カラオケアンプ１の電源回路から＋５Ｖの電圧が供給される。端子１２Ｇは接地端子であり、カラオケアンプ１のＧＮＤ線に接続されている。   On the other hand, as shown in FIG. 4, the karaoke amplifier 1 has one connector 12 on the back surface of the housing. The connector 12 is a four-terminal mini-DIN connector. In FIG. 3, the four terminals are referred to as 12A, 12B, 12H, and 12G. Terminals 12A and 12B are signal terminals. The terminal 12H is a power supply terminal, and a voltage of +5 V is supplied from the power supply circuit of the karaoke amplifier 1. The terminal 12G is a ground terminal and is connected to the GND line of the karaoke amplifier 1.

コネクタ１２の信号端子１２Ａは、ＣＰＵ１０のＲｅｍｏｔｅ０およびＲｘに接続されている。また、信号端子１２Ｂは、ＣＰＵ１０のＲｅｍｏｔｅ１およびＴｘに接続されている。   The signal terminal 12A of the connector 12 is connected to Remote 0 and Rx of the CPU 10. The signal terminal 12B is connected to Remote 1 and Tx of the CPU 10.

カラオケアンプ１の設置時には、カラオケアンプ１の設定（インストール）作業を行うため、図３（Ａ）に示すように、設定用のノートパソコン２がコネクタ１２に接続される。ノートパソコン２とカラオケアンプ１のＣＰＵ１０とはシリアル通信を行う。ノートパソコン２はＲＳ２３２Ｃコネクタを介して信号を送受信する。ＲＳ２３２Ｃインタフェースの電圧仕様は±１２Ｖである。一方、ミニＤＩＮコネクタ１２は、カラオケアンプ１の内部回路に接続されているため、ＴＴＬレベルすなわち５Ｖで信号の入出力を行う。ノートパソコン２のＲＳ２３２Ｃコネクタとカラオケアンプ１のコネクタ１２との間には信号レベル変換装置５が接続されている。信号レベル変換装置５は、ノートパソコン２から入力された±１２Ｖの信号を５Ｖの信号に変換してカラオケアンプ１のコネクタ１２に向けて出力し、カラオケアンプ１のコネクタ１２から入力された５Ｖの信号を±１２Ｖの信号に変換してノートパソコン２のＲＳ２３２Ｃコネクタに向けて出力する。この信号レベル変換装置５はカラオケアンプ１のコネクタ１２の電源端子１２Ｈから供給される電力で動作する。   When the karaoke amplifier 1 is installed, the setting notebook PC 2 is connected to the connector 12 as shown in FIG. The notebook personal computer 2 and the CPU 10 of the karaoke amplifier 1 perform serial communication. The notebook personal computer 2 transmits and receives signals via the RS232C connector. The voltage specification of the RS232C interface is ± 12V. On the other hand, since the mini-DIN connector 12 is connected to the internal circuit of the karaoke amplifier 1, it performs signal input / output at a TTL level, that is, 5V. A signal level converter 5 is connected between the RS232C connector of the notebook computer 2 and the connector 12 of the karaoke amplifier 1. The signal level conversion device 5 converts the ± 12V signal input from the notebook computer 2 into a 5V signal and outputs it to the connector 12 of the karaoke amplifier 1, and the 5V input from the connector 12 of the karaoke amplifier 1. The signal is converted to a signal of ± 12 V and output toward the RS232C connector of the notebook computer 2. The signal level conversion device 5 operates with electric power supplied from the power supply terminal 12H of the connector 12 of the karaoke amplifier 1.

図３（Ａ）の形態でノートパソコン２を接続したのち、係員が、ノートパソコン２にインストールされている設定プログラムを起動し、カラオケアンプ１の動作を設定する。設定内容は、デフォルトのボリューム、エコー設定、イコライジング、ハウリングキャンセルフィルタの設定等である。   After connecting the notebook computer 2 in the form of FIG. 3 (A), the clerk activates the setting program installed in the notebook computer 2 and sets the operation of the karaoke amplifier 1. Settings include default volume, echo settings, equalizing, howling cancellation filter settings, and the like.

カラオケアンプ１のＣＰＵ１０は、Ｒｘに信号が入力されたとき設定モード（シリアル通信動作）となる。設定モードでは、Ｒｘから入力されたパラメータで動作を設定するとともに、現在の設定状態等をＴｘから送信する。なお、Ｔｘから送信するメッセージは、ケーブルの抜き差しがされたとき、このケーブルの抜き差しを跨いで継続しない程度の短いメッセージ（１秒程度）に区切って行われる。また、コネクタ１２のケーブルが差し換えられてリモコン受信ユニット３，４が接続された場合の信号の衝突を避けるため、設定モードであってもＣＰＵ１０は積極的に信号を送信せず、相手装置（設定用ノートパソコン２）からの要求に応答してメッセージを送信する動作を行う。   The CPU 10 of the karaoke amplifier 1 enters the setting mode (serial communication operation) when a signal is input to Rx. In the setting mode, the operation is set with parameters input from Rx, and the current setting state and the like are transmitted from Tx. Note that the message transmitted from Tx is divided into short messages (about 1 second) that do not continue across the cable connection when the cable is connected or disconnected. Further, in order to avoid a signal collision when the cable of the connector 12 is replaced and the remote control receiving units 3 and 4 are connected, the CPU 10 does not actively transmit a signal even in the setting mode, and the partner device (setting In response to a request from the notebook computer 2), an operation for transmitting a message is performed.

こののち、カラオケアンプ１は通常の運用に供される。通常の運用時には、設定用のノートパソコン２は不要である。そこで、コネクタ１２に２台のリモコン受光ユニット３、４が接続される。リモコン受光ユニット３、４は、赤外線リモコンから送信される曲番号等のリモコン信号を受信する外部ユニットである。カラオケアンプを含むカラオケ装置が、利用者から見えないラック等に収納されている場合にリモコン受光ユニット３，４が外付け接続される。   After this, the karaoke amplifier 1 is used for normal operation. During normal operation, the notebook computer 2 for setting is not necessary. Therefore, the two remote control light receiving units 3 and 4 are connected to the connector 12. The remote control light receiving units 3 and 4 are external units that receive remote control signals such as music numbers transmitted from the infrared remote controller. When the karaoke apparatus including the karaoke amplifier is stored in a rack or the like that cannot be seen by the user, the remote control light receiving units 3 and 4 are externally connected.

１つのコネクタ１２に２台のリモコン受光ユニット３、４を接続するため、図５に示すようなコネクタケーブル２０を用いる。このケーブル２０は、カラオケアンプ側のプラグ２１に２つのリモコン受光ユニット側プラグ２２，２３が接続されたものである。なお リモコン受光ユニット３、４側のコネクタがオス形状であるため、プラグ２２，２３はメスプラグになっている。   In order to connect the two remote control light receiving units 3 and 4 to one connector 12, a connector cable 20 as shown in FIG. 5 is used. In this cable 20, two remote control light receiving unit side plugs 22 and 23 are connected to a plug 21 on the karaoke amplifier side. Since the connectors on the remote control light receiving units 3 and 4 are male, the plugs 22 and 23 are female plugs.

図４において、ミニＤＩＮコネクタ１２は、第１ピン１２−１〜第４ピン１２−４の４つのピンを有する。このうち、ピン１３−３が電源端子１２Ｈ、ピン１２−４が設置端子１２Ｇに対応し、ピン１２−１が信号端子１２Ａ、ピン１２−２が信号端子１２Ｂに対応する。   In FIG. 4, the mini-DIN connector 12 has four pins, a first pin 12-1 to a fourth pin 12-4. Among these, the pin 13-3 corresponds to the power supply terminal 12H, the pin 12-4 corresponds to the installation terminal 12G, the pin 12-1 corresponds to the signal terminal 12A, and the pin 12-2 corresponds to the signal terminal 12B.

図５のコネクタケーブル２０では、カラオケアンプ側プラグ２１の１番ピン（コネクタ１２のピン１２−１に対応）が第１リモコン受光ユニット側プラグ２２の第１ピンに接続され、カラオケアンプ側プラグ２１の第２ピン（コネクタ１２のピン１２−２に対応）が第２リモコン受光ユニット側プラグ２３の第１ピンに接続されている。すなわち、カラオケアンプ側プラグ２１では第１ピン、第２ピンを２つのリモコン受光ユニット側プラグ２２、２３に分岐しているが、リモコン受光ユニット側プラグ２２、２３では両方とも第１ピンに信号線が接続されている。これにより、リモコン受光ユニットは、プラグ２２、２３のどちらに接続されるかによってコネクタ（ミニＤＩＮソケット）の配線を変更する必要がない。   In the connector cable 20 of FIG. 5, the first pin of the karaoke amplifier side plug 21 (corresponding to the pin 12-1 of the connector 12) is connected to the first pin of the first remote control light receiving unit side plug 22, and the karaoke amplifier side plug 21 is connected. The second pin (corresponding to the pin 12-2 of the connector 12) is connected to the first pin of the second remote control light receiving unit side plug 23. That is, in the karaoke amplifier side plug 21, the first pin and the second pin are branched into two remote control light receiving unit side plugs 22 and 23, but in both the remote control light receiving unit side plugs 22 and 23, the signal line is connected to the first pin. Is connected. Thereby, the remote control light receiving unit does not need to change the wiring of the connector (mini DIN socket) depending on which of the plugs 22 and 23 is connected.

図３（Ｂ）において、リモコン受光ユニット３が受光したリモコン信号は、コネクタ１２の信号端子１２Ａを介してＣＰＵ１０のＲｅｍｏｔｅ０端子に入力され、リモコン受光ユニット４が受光したリモコン信号は、コネクタ１２の信号端子１２Ｂを介してＣＰＵ１０のＲｅｍｏｔｅ１端子に入力される。カラオケアンプ１のＣＰＵ１０は、Ｒｅｍｏｔｅ０またはＲｅｍｏｔｅ１に信号が入力されたとき通常動作モード（信号受信動作）となり、曲番号を受信して演奏を再生する動作を行う。   In FIG. 3B, the remote control signal received by the remote control light receiving unit 3 is input to the Remote 0 terminal of the CPU 10 via the signal terminal 12A of the connector 12, and the remote control signal received by the remote control light receiving unit 4 is the signal of the connector 12. The signal is input to the Remote1 terminal of the CPU 10 via the terminal 12B. The CPU 10 of the karaoke amplifier 1 enters a normal operation mode (signal reception operation) when a signal is input to Remote0 or Remote1, and performs an operation of receiving a song number and reproducing a performance.

なお、図５に示したコネクタケーブルは、リモコン受光ユニット側プラグ２２、２３ メスプラグ（中継プラグ）としているが、プラグ２２、２３をオスプラグとしてもよい。   In addition, although the connector cable shown in FIG. 5 uses the remote control light receiving unit side plugs 22 and 23 as female plugs (relay plugs), the plugs 22 and 23 may be male plugs.

また、この実施形態は、カラオケアンプ１に設定用ノートパソコン２と２台のリモコン受光ユニット３、４を接続する例について説明したが、本発明はこれに限定されず、他の電子機器に適用することも可能である。   Moreover, although this embodiment demonstrated the example which connects the notebook personal computer 2 for setting and the two remote control light-receiving units 3 and 4 to the karaoke amplifier 1, this invention is not limited to this, It applies to another electronic device It is also possible to do.
