Description

  The present invention relates to an electronic apparatus such as a television receiver provided with a remote control device.

  In general, an electronic device such as a television receiver includes a remote control device for remotely operating an electronic device main body. For example, in a television receiver, a control signal (hereinafter referred to as a “remote control signal”) for remotely operating the electronic device main body is transmitted from the remote control device to the television in accordance with the operation content of the operation unit provided in the remote control device. By transmitting to the receiver main body, the channel and volume of the TV main body are operated.

  Also, in general, electronic devices equipped with a remote control device employ a locator function (position detection function) to search for the remote control device when the location of the remote control device becomes unknown due to misplacement or loss of the remote control device. Has been. More specifically, for example, an operation button for searching for a remote control device and a position detection signal transmitting unit for transmitting a signal for detecting the position of the remote control device (hereinafter referred to as “position detection signal”) are provided. There is disclosed an electronic device comprising: an electronic device main body; a position detection signal receiving unit for receiving a position detection signal transmitted from the electronic device main body; and a remote control device provided with a notification unit for reporting the position of the remote control device. Yes. When the location of the remote control device is not known, when a predetermined operation is performed with the operation switch of the electronic device body, a predetermined position detection signal is transmitted from the position detection signal transmission unit. In the notification unit, a sound is generated for a predetermined period to notify the user of the position of the remote control device (see, for example, Patent Document 1).

  Further, when there is another television receiving device having another remote control device in the vicinity of the television receiving device having the remote control device (for example, an adjacent room), the remote control device is searched for a remote location device whose location is unknown. In addition, when the position detection signal is transmitted, there is a disadvantage that sound is generated not only from the remote control device being searched but also from other remote control devices. In addition, the remote control signal transmitted from another remote control device manipulates the channel, volume, etc. of the television receiver, causing a malfunction on the television body side.

  Therefore, in order to avoid such inconvenience, a method of setting an identification code (ID code) in the remote control device is adopted. By such a method, it becomes possible to generate and report sound only from a remote control device in which the same identification code as the identification code set in the television main body that is the electronic device main body is set. It is described that even when there are a plurality of attached remote control devices, it is possible to search for a specific remote control device whose location is unknown (see, for example, Patent Document 2).

Similarly, even when one electronic device (for example, a television receiver) includes a plurality of remote control devices (see, for example, Patent Document 3), by setting an identification code for each of the plurality of remote control devices, It is possible to generate and notify the sound only from the remote control device in which the same identification code as the identification code set in the electronic device body is set. Therefore, even when there are a plurality of remote control devices attached to one electronic device, it is possible to search for only a specific remote control device whose location is unknown.

The notification stop switch 36 is for stopping notification by the notification unit 16. As shown in FIG. 2, the remote control device 3 is provided with a battery 34 as a power source for the remote control device 3. Further, since the external configuration of the remote control devices 23 and 24 is the same as the external configuration of the remote control device 3 shown in FIG. 2, detailed description thereof is omitted here.

  Under the above configuration, when the user operates the operation unit 11 of the remote control device 3 (or the remote control devices 23 and 24), the CPU 17 transmits a remote control signal corresponding to the operation content of the operation unit 11. The remote control signal transmission unit 12 transmits a remote control signal corresponding to the operation content of the operation unit 11 as an electrical signal based on the control signal. Next, in the light emitting element 13, a remote control signal that is an electrical signal is converted into an optical signal such as infrared rays, and the optical signal is emitted toward the electronic device main body 2. Next, the light receiving element 4 of the electronic device body 2 receives a remote control signal that is an optical signal, and converts the remote control signal that is an optical signal into an electrical signal in accordance with the amount of light of the received optical signal. Next, the remote control signal converted into the electrical signal is received by the remote control signal receiving unit 5 and is input to the CPU 10 via the remote control signal receiving unit 5. The CPU 10 is configured to control the electronic device main body 2 based on the remote control signal (for example, when the electronic device main body 2 is a television receiver main body, control of the channel, volume, etc.).

  Here, the present embodiment is characterized in that the notification unit 16 generates different sounds corresponding to the identification codes set in the respective remote control devices 3, 23, and 24. More specifically, as shown in FIG. 1, in each of the remote control devices 3, 23, and 24, the notification unit 16 is provided with a plurality (three in this embodiment) of sound generation members 25 to 27. Yes. These sound generating members 25 to 27 generate different sounds, and each of the sound generating members 25 to 27 outputs a sound corresponding to one of the identification codes set in the remote control devices 3, 23, and 24. It has a configuration that occurs. For example, when the identification code set in the remote control device 3 is R1, the identification code set in the remote control device 23 is R2, and the identification code set in the remote control device 24 is R3, the sounding member 25 is in the remote control device 3. The sound is generated corresponding to the set identification code R1, the sound generation member 26 generates sound corresponding to the identification code R2 set in the remote control device 23, and the sound generation member 27 is set in the remote control device 24. The voice is generated corresponding to the identification code R3. With such a configuration, a plurality of identification codes R1 to R3 are set even when searching for a remote control device (for example, the remote control device 24) whose location is unknown by using all the set identification codes R1 to R3. Since different voices are generated in the remote control devices 3, 23, 24, it becomes easy to identify the remote control device 24 whose location is unknown by voice, and as a result, search for the remote control device whose location is unknown Will be very easy.

  Next, a procedure for searching for a remote control device whose location is unknown will be described. FIG. 3 is a flowchart showing a procedure for searching for a remote control device in the electronic apparatus according to the first embodiment of the present invention. Here, among the plurality of remote control devices 3, 23, 24, the location of the remote control device 24 is not known, and all the identification codes R1 to R3 set in the remote control devices 3, 23, 24 are used. A case of searching for the remote control device 24 whose location is unknown will be described. A case will be described in which the identification code R3 of the remote control device 24 whose location is unknown is unknown to the user.

  Since the identification code R3 of the remote control device 24 whose location is no longer known is unknown, the remote control device 24 whose location is no longer known is searched using all the identification codes R1 to R3. Therefore, first, the user operates the remote control device search operation switch 6 provided in the electronic device main body 2 in order to transmit a position detection signal including the identification code R1 of the remote control device 3 (step S1). Then, the CPU 10 detects the operation of the operation switch 6 to generate a position detection signal including the identification code R1 of the remote control device 3, and to the position detection signal transmission unit 9, the position detection signal including the identification code R1. The position detection signal transmitter 9 generates a position detection signal including the identification code R1 modulated to a predetermined radio wave via the transmission antenna 8 for a predetermined period (for example, For 30 seconds) (step S2).

  Next, the position detection signal receiving unit 15 of the remote control devices 3, 23, and 24 receives the position detection signal including the identification code R <b> 1 transmitted from the electronic device main body 2 via the reception antenna 14, and A detection signal is input to the CPU 17 (step S3). At this time, the CPU 17 of each remote control device 3, 23, 24 stores the identification code R1 included in the received position detection signal in the identification code storage unit 19 of each remote control device 3, 23, 24. Analyzes whether or not it matches the identification code. That is, in the remote controller 3, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R1, which matches the identification code R1 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 3 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 3, and the notification unit 16 keeps the remote control device 3 for a predetermined period (for example, 30 seconds). A sound is generated by the sound generation member 25 that generates sound corresponding to the identification code R1 set in step S1, and the position of the remote control device 3 is notified to the user (step S4).

  On the other hand, in the remote controller 23, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R2, which matches the identification code R1 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 23 does not generate a control signal so as to notify the notification unit 16 of the position of the remote control device 23, and the notification unit 16 uses the identification code R <b> 2 set in the remote control device 23. Correspondingly, no sound is generated by the sound generating member 26 that generates sound.

  Similarly, in the remote controller 24, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R3, and the identification code R1 included in the received position detection signal is Since they do not match, the CPU 17 of the remote control device 24 does not generate a control signal to notify the notification unit 16 of the position of the remote control device 24, and the notification unit 16 recognizes the identification set in the remote control device 24. No sound is generated by the sound generating member 27 that generates sound corresponding to the code R3.

  In the present embodiment, in order to reduce the power consumption of the remote control devices 3, 23, and 24 and to suppress the consumption of the battery 34 as the power source, the reception antenna 14 and the position detection signal receiving unit 15 are used. Thus, power is supplied every predetermined period (for example, every 10 seconds) for a predetermined period (for example, 5 seconds).

  Next, in order to transmit a position detection signal including the identification code R2 of the remote control device 23, the user operates the remote control device search operation switch 6 provided in the electronic device main body 2 (step S5). Then, the CPU 10 detects the operation of the operation switch 6 to generate a position detection signal including the identification code R2 of the remote control device 23 and to the position detection signal transmitting unit 9 a position detection signal including the identification code R2. The position detection signal transmitting unit 9 generates a position detection signal including the identification code R2 modulated to a predetermined radio wave via the transmission antenna 8 for a predetermined period (for example, For 30 seconds (step S6).

  Next, the position detection signal receiving unit 15 of the remote control devices 23 and 24 receives the position detection signal including the identification code R2 transmitted from the electronic device main body 2 via the reception antenna 14, and the position detection signal Is input to the CPU 17 (step S7). Then, the CPU 17 of each remote control device 23, 24 confirms that the identification code R2 included in the received position detection signal matches the identification code stored in the identification code storage unit 19 of each remote control device 23, 24. Analyze whether or not. That is, in the remote control device 23, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R2, which matches the identification code R2 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 23 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 23, and the notification unit 16 keeps the remote control device 23 for a predetermined period (for example, 30 seconds). The sound generation member 26 that generates sound corresponding to the identification code set in R2 generates a sound different from the sound generated by the sound generation member 25 of the remote control device 3, and the position of the remote control device 23 is indicated to the user. Notification is made (step S8).

  On the other hand, in the remote control device 24, since the set identification code is R3 and does not match the identification code R2 included in the received position detection signal, the CPU 17 of the remote control device 24 notifies the notification unit 16. The control unit does not generate a control signal so as to notify the position of the remote control device 24, and the notification unit 16 does not generate sound by the sound generation member 27 that generates sound corresponding to the identification code R3 set in the remote control device 24. become.

  Next, in order to transmit a position detection signal including the identification code R3 of the remote control device 24, the user operates the remote control device search operation switch 6 provided in the electronic device main body 2 (step S9). Then, the CPU 10 detects the operation of the operation switch 6 to generate a position detection signal including the identification code R3 of the remote control device 24, and to the position detection signal transmission unit 9, the position detection signal including the identification code R3. The position detection signal transmitter 9 generates a position detection signal including the identification code R3, which is modulated into a predetermined radio wave via the transmission antenna 8, for a predetermined period (for example, For 30 seconds) (step S10).

  Next, the position detection signal receiving unit 15 of the remote control device 24 receives the position detection signal including the identification code R3 transmitted from the electronic device main body 2 via the reception antenna 14, and the position detection signal is received by the CPU 17. (Step S11). Then, the CPU 17 of the remote control device 24 analyzes whether or not the identification code R3 included in the received position detection signal matches the identification code stored in the identification code storage unit 19 of the remote control device 24. That is, in the remote control device 24, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R3, which matches the identification code R3 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 24 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 24, and the notification unit 16 keeps the remote control device 24 for a predetermined period (for example, 30 seconds). The sound generation member 27 that generates sound corresponding to the identification code R3 set in step S3 generates sound different from the sound generated by the sound generation member 25 of the remote control device 3 and the sound generation member 26 of the remote control device 23, The user is notified of the position of the remote control device 24 (step S12).

  At this time, since these sound generating members 25 to 27 generate different sounds, the user can easily identify the remote control device 24 whose location is unknown by voice, and the remote control whose location is unknown. The device 24 can be easily searched. That is, as described above, even when searching for the remote control device 24 whose location is no longer known by all the set identification codes R1 to R3, the plurality of remote control devices 3 and 23 to which the identification codes R1 to R3 are set. , 24, different voices are generated, so that it becomes easy to identify the remote control device 24 whose location is unknown by voice, and as a result, it becomes easy to search for the remote control device whose location is unknown.

  When the location of the remote control device 24 is determined, it is necessary to forcibly stop the notification of the sound generated by the sound generation members 25 to 27 and stop the notification by the notification unit 16, so that the remote control devices 3, 23, and 24 are stopped. By operating the notification stop switch 36 in each of the above, the notification by the notification unit 16 can be stopped (step S13). More specifically, when the operation of the notification stop switch 36 is performed, the CPU 17 generates a control signal to the notification unit 16 and stops the sound notification by the sound generation members 25 to 27 in the notification unit 16.

  Even when the location of the remote control device 3 (or the remote control device 23) is not known, the remote control device 3 (or the remote control device 23) whose location is no longer known is searched for by the same steps as the above steps S1 to S13. can do.

According to the present embodiment described above, the following effects can be obtained.
(1) In the electronic device 1 of the present embodiment, the notification unit 16 has a plurality of sound generation members 25 to 27 that generate different sounds. Further, in correspondence with the identification codes R1 to R3 set in each of the plurality of remote control devices 3, 23 and 24, any one of the plurality of sounding members 25 to 27 (for example, the identification code is R3). In this case, a sound is generated by the sound generation member 27). Accordingly, the identification code of the remote control device (for example, the remote control device 24) whose location is no longer known is unknown, and the remote control device 24 whose location is no longer known is searched using all the set identification codes R1 to R3. In addition, different sounds are generated in each of the plurality of remote control devices 3, 23, and 24 in which the identification codes R1 to R3 are set. Therefore, it becomes easy to identify the remote control device 24 whose location is unknown by voice, and as a result, it becomes very easy to search for the remote control device 24 whose location is unknown.

Then, the CPU 17 of each of the remote control devices 3, 23, 24 uses the identification code R 1 included in the received position detection signal as the identification code stored in the identification code storage unit 19 of each of the remote control devices 3, 23, 24. Analyze whether or not they match. That is, in the remote controller 3, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R1, which matches the identification code R1 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 3 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 3. Then, in the notification unit 16, the audio data processing unit 41 reads out the audio data corresponding to the identification code R1 from the audio data stored in the audio data storage unit 40, and processes the audio data into an audio signal. The sound generation member 42 generates a sound based on the sound signal corresponding to the identification code R1 converted by the sound data processing unit 41 for a predetermined period (for example, 30 seconds), and the position of the remote control device 3 is changed. The user is notified (step S24).

  On the other hand, in the remote control device 23, since the set identification code is R2 and does not coincide with the identification code R1 included in the received position detection signal, the CPU 17 of the remote control device 23 notifies the notification unit 16. The control signal is not generated so as to notify the position of the remote control device 23. Therefore, in the notification unit 16, the voice data stored in the voice data storage unit 40 is not read and processed by the voice data processing unit 41, and no sound is generated by the sound generation member 42.

  Similarly, in the remote control device 24, since the set identification code is R3 and does not match the identification code R1 included in the received position detection signal, the CPU 17 of the remote control device 24 uses the notification unit 16. On the other hand, no control signal is generated so as to notify the position of the remote control device 24. Therefore, in the notification unit 16, the voice data stored in the voice data storage unit 40 is not read and processed by the voice data processing unit 41, and no sound is generated by the sound generation member 42.

  Next, in order to transmit the position detection signal including the identification code R2 of the remote control device 23, the user operates the remote control device search operation switch 6 provided in the electronic device main body 2 (step S25). Then, the CPU 10 detects the operation of the operation switch 6 to generate a position detection signal including the identification code R2 of the remote control device 23 and to the position detection signal transmitting unit 9 a position detection signal including the identification code R2. The position detection signal transmitting unit 9 generates a position detection signal including the identification code R2 modulated to a predetermined radio wave via the transmission antenna 8 for a predetermined period (for example, , For 30 seconds) (step S26).

  Next, the position detection signal receiving unit 15 of the remote control devices 23 and 24 receives the position detection signal including the identification code R2 transmitted from the electronic device main body 2 via the reception antenna 14, and the position detection signal Is input to the CPU 17 (step S27). Then, the CPU 17 of each remote control device 23, 24 confirms that the identification code R2 included in the received position detection signal matches the identification code stored in the identification code storage unit 19 of each remote control device 23, 24. Analyze whether or not. That is, in the remote control device 23, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R2, which matches the identification code R2 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 23 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 23. Then, in the notification unit 16, the audio data processing unit 41 reads out the audio data corresponding to the identification code R2 from the audio data stored in the audio data storage unit 40, and processes the audio data into an audio signal. The sound generation member 42 of the remote control device 3 is generated based on the sound signal corresponding to the identification code R2 converted and converted by the sound data processing unit 41 for a predetermined period (for example, 30 seconds). A voice different from the current voice is generated to notify the user of the position of the remote control device 23 (step S28).

  On the other hand, in the remote control device 24, since the set identification code is R3 and does not match the identification code R2 included in the received position detection signal, the CPU 17 of the remote control device 24 notifies the notification unit 16. The control signal is not generated so as to notify the position of the remote control device 24. Therefore, in the notification unit 16, the voice data stored in the voice data storage unit 40 is not read and processed by the voice data processing unit 41, and no sound is generated by the sound generation member 42.

  Next, in order to transmit a position detection signal including the identification code R3 of the remote control device 24, the user operates the remote control device search operation switch 6 provided in the electronic device main body 2 (step S29). Then, the CPU 10 detects the operation of the operation switch 6 to generate a position detection signal including the identification code R3 of the remote control device 24, and to the position detection signal transmission unit 9, the position detection signal including the identification code R3. The position detection signal transmitter 9 generates a position detection signal including the identification code R3, which is modulated into a predetermined radio wave via the transmission antenna 8, for a predetermined period (for example, For 30 seconds (step S30).

  Next, the position detection signal receiving unit 15 of the remote control device 24 receives the position detection signal including the identification code R3 transmitted from the electronic device main body 2 via the reception antenna 14, and the position detection signal is received by the CPU 17. (Step S31). Then, the CPU 17 of the remote control device 24 analyzes whether or not the identification code R3 included in the received position detection signal matches the identification code stored in the identification code storage unit 19 of the remote control device 24. That is, in the remote control device 24, the set identification code (that is, the identification code stored in the identification code storage unit 19) is R3, which matches the identification code R3 included in the received position detection signal. Therefore, the CPU 17 of the remote control device 24 generates a control signal so as to notify the notification unit 16 of the position of the remote control device 24. Then, in the notification unit 16, the audio data processing unit 41 reads out the audio data corresponding to the identification code R3 from the audio data stored in the audio data storage unit 40, and processes the audio data into an audio signal. The sound generation member 42 of the remote control device 3 and the remote control device are converted based on the sound signal corresponding to the identification code R3 converted by the sound data processing unit 41 for a predetermined period (for example, 30 seconds). A sound different from the sound generated by the sound generating member 42 is generated to notify the user of the position of the remote control device 24 (step S32).

  At this time, since the sound generating members 42 of the remote control devices 3, 23, and 24 generate different sounds, the user can easily identify the remote control device 24 whose location is unknown by using the sound. Thus, it becomes possible to easily search for the remote control device 24 that has become unknown. That is, as described above, even when searching for the remote control device 24 whose location is no longer known by all the set identification codes R1 to R3, the plurality of remote control devices 3 and 23 to which the identification codes R1 to R3 are set. , 24, different voices are generated, so that it becomes easy to identify the remote control device 24 whose location is unknown by voice, and as a result, it becomes easy to search for the remote control device whose location is unknown.

  When the location of the remote control device 24 is determined, it is necessary to forcibly stop the notification of the sound generated by the sound generation member 42 and stop the notification by the notification unit 16, so that each of the remote control devices 3, 23, 24 is stopped. The notification by the notification unit 16 can be stopped by operating the notification stop switch 36 in (Step S33). More specifically, when the operation of the notification stop switch 36 is performed, the CPU 17 generates a control signal for the notification unit 16 and stops the sound notification by the sound generation member 42 in the notification unit 16.

  Even when the location of the remote control device 3 (or the remote control device 23) is not known, the remote control device 3 (or the remote control device 23) whose location is no longer known is searched by the same steps as the above-described steps S21 to S33. can do.

According to the present embodiment described above, the following effects can be obtained.

Accordingly, the identification code of the remote control device (for example, the remote control device 24) whose location is no longer known is unknown, and the remote control device 24 whose location is no longer known is searched using all the set identification codes R1 to R3. In addition, different sounds are generated in each of the plurality of remote control devices 3, 23, and 24 in which the identification codes R1 to R3 are set. Therefore, it becomes easy to identify the remote control device 24 whose location is unknown by voice, and as a result, it becomes very easy to search for the remote control device 24 whose location is unknown.

In addition, you may change the said embodiment as follows.

It can be set as the structure which performs the process for changing. With such a configuration, the user can arbitrarily set the sound generated in the sound generation members 25 to 27 to a desired sound.
