Description
【０００１】[0001]
本発明は、テレビジョン受像機やビデオテープレコーダや衛星放送受信機等の 被制御機器を遠隔制御するのに使用するワイヤレス遠隔制御送信機に関する。 The present invention relates to a wireless remote control transmitter used for remotely controlling controlled equipment such as a television receiver, a video tape recorder and a satellite broadcast receiver.
【０００２】[0002]
従来、ワイヤレス遠隔制御送信機としては、赤外線を遠隔制御情報によって変 調して送信する赤外線方式のものや、電波を遠隔制御情報によって変調して送信 する電波式のものや、赤外線及び電波を遠隔制御情報によって同時に変調送信す る赤外線及び電波同時発射方式のものがあった。 Conventionally, wireless remote control transmitters use an infrared method that modulates and transmits infrared rays according to remote control information, a radio wave type that modulates radio waves according to remote control information, and sends infrared and radio waves remotely. There was an infrared and radio wave simultaneous emission system that simultaneously modulates and transmits according to control information.
【０００３】[0003]
しかし、赤外線方式のものは、ノイズには強いが、遠隔制御信号の到達距離が 短いという問題点があった。また、電波方式のものは、反対に遠隔制御信号の到 達距離が長いが、ノイズには弱いという問題点があった。また、赤外線及び電波 同時発射方式のものは、赤外線方式及び電波方式双方の長所を備えているが、赤 外線及び電波を同時に発射するので、消費電力が大きくなる。一般に、このよう な遠隔制御送信機は、電源として小型の電池を使用することが多いので、消費電 力が大きいと、電池の消耗が速くなり、頻繁に電池を取り替える必要があるとい う問題点があった。 However, the infrared type has a problem that the remote control signal can reach a short distance although it is strong against noise. On the contrary, the radio wave type has a problem that the remote control signal has a long reach but is weak against noise. In addition, the infrared and radio wave simultaneous emission methods have the advantages of both the infrared and radio wave methods, but since they emit infrared rays and radio waves at the same time, they consume a large amount of power. In general, such remote control transmitters often use a small battery as a power source.Therefore, if the power consumption is large, the battery will be consumed quickly and the battery must be replaced frequently. was there.
【０００４】 本考案は、赤外線及び電波同時発射方式の利点を生かしながら、消費電力の低 減を図った遠隔制御送信機を提供することを目的とする。It is an object of the present invention to provide a remote control transmitter that reduces power consumption while taking advantage of the simultaneous infrared and radio wave emission methods.
【０００５】[0005]
上記の目的を達成するために、本考案は、操作手段に対する操作に応じて被制 御機器に対する制御情報を生成する制御情報生成手段と、上記制御情報に応じた 赤外線信号を送信する赤外線送信手段と、上記制御情報に応じた電波を送信する 電波送信手段と、上記制御情報生成手段と上記両送信手段との間に介在し上記制 御情報を上記両送信手段のうち選択されたものに選択供給する選択供給手段とを 、１つの筐体内に設けてなるものである。 In order to achieve the above object, the present invention provides a control information generating means for generating control information for a controlled device according to an operation on an operating means, and an infrared transmitting means for transmitting an infrared signal according to the control information. And a radio wave transmitting means for transmitting a radio wave according to the control information and a control information generating means interposed between the control information generating means and the both transmitting means to select the control information to the selected one of the both transmitting means. The selective supply means for supplying is provided in one housing.
【０００６】[0006]
本考案によれば、選択供給手段によって、制御情報生成手段からの制御情報を 赤外線送信手段に供給する状態にすれば、制御情報に応じた赤外線が送信される 。また、選択供給手段によって、制御情報生成手段からの制御情報を電波送信手 段に供給する状態にすれば、制御情報に応じた電波が送信される。即ち、赤外線 送信手段及び電波送信手段が、同時に送信動作をすることはない。 According to the present invention, when the selective supply means brings the control information from the control information generation means into the infrared transmission means, the infrared light corresponding to the control information is transmitted. Further, when the selective supply means brings the control information from the control information generating means to the radio wave transmitting means, the radio wave according to the control information is transmitted. That is, the infrared transmission means and the radio wave transmission means do not simultaneously perform transmission operations.
【０００７】[0007]
本実施例のワイヤレス遠隔制御送信機１０では、図２に示すように筐体１２の 上面に、複数の操作キーからなる操作部１４が配置されている。図１に示すよう に、操作部１４の操作に応じて信号処理部１６が、被制御機器１８に対する制御 情報、例えば被制御機器１８が衛星放送受信機の場合、電源オンやチャンネル切 換等の制御情報を発生する。 In the wireless remote control transmitter 10 of the present embodiment, as shown in FIG. 2, the operation unit 14 including a plurality of operation keys is arranged on the upper surface of the housing 12. As shown in FIG. 1, in response to the operation of the operation unit 14, the signal processing unit 16 causes the control information for the controlled device 18, for example, when the controlled device 18 is a satellite broadcast receiver, power-on, channel switching, etc. Generate control information.
【０００８】 信号処理部１６で発生した制御情報は、切換部２０を介して赤外線送信回路２ ２または電波送信回路２４のいずれかに供給される。送信回路２２、２４のいず れかに制御情報を供給するための切換部２０の切換制御が、例えば図２に示す操 作部１４の特定のキー、例えばキー１４ａを操作することによって、信号処理部 １６の信号が切り換えられて実行される。The control information generated in the signal processing unit 16 is supplied to either the infrared transmission circuit 22 or the radio wave transmission circuit 24 via the switching unit 20. The switching control of the switching unit 20 for supplying the control information to either of the transmission circuits 22 and 24 is controlled by operating a specific key of the operating unit 14 shown in FIG. 2, for example, the key 14a. The signal of the processing unit 16 is switched and executed.
【０００９】 例えば制御情報が赤外線送信回路２２に供給されるように切換部２０が切換制 御されている状態で、キー１４ａを操作すると、切換部２０は、制御情報を電波 送信回路２４に供給する状態に切換制御される。この状態で、再びキー１４ａを 操作すると、再び切換部２０は、制御情報を赤外線送信回路２２に供給する状態 に切換制御される。以下、同様に、キー１４ａを操作するごとに、今まで供給さ れていた送信回路とは別の送信回路に制御情報が供給される。For example, when the key 14a is operated while the switching unit 20 is controlled to switch so that the control information is supplied to the infrared transmission circuit 22, the switching unit 20 supplies the control information to the radio wave transmission circuit 24. It is controlled to switch to a state in which it is turned on. When the key 14a is operated again in this state, the switching section 20 is again controlled to switch to the state in which the control information is supplied to the infrared transmitting circuit 22. Thereafter, similarly, each time the key 14a is operated, the control information is supplied to a transmission circuit different from the transmission circuit that has been supplied so far.
【００１０】 赤外線送信回路２２は、切換部２０を介して供給された制御情報に応じて変調 された赤外線を赤外線発光素子２６が発光するように赤外線発光素子２６を制御 する。The infrared transmission circuit 22 controls the infrared light emitting element 26 so that the infrared light emitting element 26 emits infrared light modulated according to the control information supplied via the switching unit 20.
【００１１】 また、電波送信回路２４は、切換部２０を介して供給された制御情報に応じて 高周波搬送波信号を変調し、アンテナ２８から送信する。Further, the radio wave transmission circuit 24 modulates a high frequency carrier signal according to the control information supplied via the switching unit 20, and transmits it from the antenna 28.
【００１２】 なお、ワイヤレス遠隔制御送信機１０の操作部１４、信号処理部１６、切換部 ２０、赤外線送信回路２２、電波送信回路２４を駆動するための電力は、図示し ていないが、筐体１２内に設けた電池から供給されている。Power for driving the operation unit 14, the signal processing unit 16, the switching unit 20, the infrared transmission circuit 22, and the radio wave transmission circuit 24 of the wireless remote control transmitter 10 is not shown in the figure, but is not shown. It is supplied from a battery provided inside 12.
【００１３】 赤外線発光素子２６から送信された赤外線信号は、被制御機器１８の近傍に設 けられた赤外線受信部３０によって受信される。この赤外線受信部３０によって 復調された制御情報は、制御部３２に供給される。The infrared signal transmitted from the infrared light emitting element 26 is received by the infrared receiver 30 provided near the controlled device 18. The control information demodulated by the infrared receiver 30 is supplied to the controller 32.
【００１４】 また、アンテナ２８から送信された電波も、被制御機器１８の近傍に配置され た電波受信部３４によって受信される。この受信部３４によって復調された制御 情報も制御部３２に供給される。Further, the radio wave transmitted from the antenna 28 is also received by the radio wave receiving section 34 arranged near the controlled device 18. The control information demodulated by the receiver 34 is also supplied to the controller 32.
【００１５】 なお、上述したように赤外線発光素子２６からの赤外線の発光及びアンテナ２ ８からの電波の送信が同時に行われることはないので、赤外線受信部３０と電波 受信部３４とが同時に受信動作を行うことはない。As described above, since the infrared light emitting element 26 does not emit infrared light and the antenna 28 does not transmit radio waves at the same time, the infrared receiving section 30 and the radio wave receiving section 34 simultaneously perform a receiving operation. Never do.
【００１６】 制御部３２は、赤外線受信部３０または電波受信部３４から供給された制御情 報に応じて被制御機器１８を制御する。The control unit 32 controls the controlled device 18 according to the control information supplied from the infrared receiving unit 30 or the radio wave receiving unit 34.
【００１７】 このようなワイヤレス遠隔制御送信機１０では、例えば遠隔制御信号の到達距 離よりも耐ノイズ性を重視する必要のある場合、キー１４ａを操作して、操作部 １４の操作によって生成された制御情報が、信号処理部１６から切換部２０を介 して赤外線送信回路２２に供給されるようにする。これによって赤外線発光素子 ２６から制御情報に応じた赤外線が送信される。In such a wireless remote control transmitter 10, for example, when it is necessary to emphasize noise resistance rather than the reaching distance of the remote control signal, the key 14 a is operated to generate the operation by the operation unit 14. The control information is supplied from the signal processing unit 16 to the infrared transmission circuit 22 via the switching unit 20. As a result, infrared rays corresponding to the control information are transmitted from the infrared light emitting element 26.
【００１８】 また、耐ノイズ性よりも遠隔制御信号の到達距離を重視する必要のある場合、 キー１４ａを操作して、制御情報が、信号処理部１６から切換部２０を介して電 波送信回路２４に供給されるようにする。これによって、アンテナ２８から制御 情報に応じた電波が送信される。In addition, when it is necessary to place importance on the reaching distance of the remote control signal rather than the noise resistance, the key 14 a is operated, and the control information is transmitted from the signal processing unit 16 via the switching unit 20 to the radio transmission circuit. 24. This causes the antenna 28 to transmit a radio wave according to the control information.
【００１９】 上記の実施例では、切換部２０によって制御情報の供給を赤外線送信回路２２ 及び電波送信回路２４の一方に切換供給するように構成したが、これに加えて、 切換によって制御情報が供給された送信回路にのみ動作電力を供給するように、 両送信回路と電源との間に電源切換部を設け、この電源切換部の切換制御と切換 部２０による制御情報の切換制御とを同期させて行ってもよい。なお、上記実施 例では、切換部２０の操作キー１４ａを１つのキーで行なったが、赤外線信号送 信用と電波送信用とを別々の操作キーとしてもよいし、またスライドスイッチに よる切換でもよいし、回転式スイッチでもよい。In the above embodiment, the switching unit 20 is configured to switch and supply the control information to one of the infrared transmission circuit 22 and the radio wave transmission circuit 24. In addition to this, the control information is supplied by switching. In order to supply operating power only to the selected transmission circuit, a power supply switching unit is provided between the two transmission circuits and the power supply, and the switching control of this power supply switching unit and the switching control of the control information by the switching unit 20 are synchronized. You may go. In the above embodiment, one key is used as the operation key 14a of the switching unit 20, but the infrared signal transmission and the radio wave transmission may be different operation keys, or may be changed by a slide switch. However, a rotary switch may be used.
【００２０】[0020]
以上のように、本考案によれば、信号処理部からの制御情報は、耐ノイズ性を 重視するか、遠隔制御信号の到達距離を重視するかに応じて、選択供給手段によ って赤外線送信手段及び電波送信手段のいずれか一方にのみ供給される。従って 、遠隔制御送信機の使用環境に最適な状態で遠隔制御信号を送信することができ る上に、両送信手段が同時に動作することがなく、１つの筐体内に両送信手段や 信号処理手段を設けて、これらを電池駆動しているような場合でも、消費電力が 余り大きくなく、電池の消耗を減らすことができ、頻繁に電池を取り替える必要 はない。 As described above, according to the present invention, the control information from the signal processing unit is selected by the selective supply means according to whether the noise resistance or the remote control signal distance is emphasized. It is supplied to only one of the transmitting means and the radio wave transmitting means. Therefore, the remote control signal can be transmitted in an optimal state for the usage environment of the remote control transmitter, and both transmitting means do not operate simultaneously, so that both transmitting means and signal processing means can be accommodated in one housing. Even when these are driven by batteries, the power consumption is not so large, the battery consumption can be reduced, and it is not necessary to replace the batteries frequently.
