Description

  The present invention relates to an electric device in which a plurality of operations including power-on are performed by a signal from a remote control transmitter and a control method thereof.

  In general, various controls are performed by a remote control transmitter in a large household electric appliance. For example, in a television receiver, power-on and channel selection operations can be performed by key operations of a remote control transmitter at hand of the user. The remote control transmitter transmits signals for performing these operations to the television receiver main body by infrared communication or the like. For this reason, the user was able to perform these operations even from a distance of 2 m or more from the television receiver body.

  Such operation by the remote control transmitter is convenient for the user, but the remote control transmitter is generally small enough to be operated by the user with one hand. For this reason, the number of operation keys provided in the remote control transmitter is approximately 20 or less, which is insufficient for controlling all functions of the television receiver. On the other hand, when the number of operation keys is large, it may take time for the user to search for a desired operation key. In view of this, various methods have been proposed for improving these problems and making it easier for the user to operate the remote control transmitter.

  Patent Literature 1 describes a technique for performing various different controls by operating the same operation key a plurality of times. As a result, the user can perform various controls even when using a remote control transmitter with a small number of operation keys.

  Japanese Patent Application Laid-Open No. 2003-228561 describes a technique that can freely change the layout of each operation key (touch panel), and in particular, changes the operation key layout based on the frequency of use. As a result, operation keys that are frequently used are rearranged at positions that are easy to identify and operate for the user, and are particularly easy to operate.

  Of the operations performed by the user, a particularly important operation is power-on that is always performed at the beginning of use of the device. For example, a “power” key used for this operation is provided at the extreme end of the operation key array in a color different from that of other operation keys to improve identification and make it easier to operate.

Thus, by devising the operation and arrangement of the operation keys in the remote control transmitter, an electric device that is easy for the user to operate is obtained.

  However, especially with respect to the operation of turning on the power, the operation is often performed in a different situation from the other operation keys. For example, the power of a television receiver is always turned on at the beginning of its use, and is often done immediately after the user returns home in a general household. However, in the case of returning home at night, in the state immediately after returning home, the room light is not yet sufficiently lit and the room is often dark. In the case of a television receiver having a large display, the screen may be used instead of the room light. For this reason, it is preferable that the power can be easily turned on even when the room is dark, but this operation is not easy when the room is dark by any of the conventional methods described above. For this reason, the user cannot perform this reliable operation until the room is sufficiently bright. For this reason, there has been a demand for an electric device and a control method therefor that can reliably turn on power even in an environment where it is difficult to operate the remote control transmitter.

  Hereinafter, an embodiment in which the present invention is applied to a television receiver as an electric device will be described.

(First embodiment)
FIG. 1 is a configuration diagram of a television receiver 1 according to the first embodiment of the present invention. The television receiver 1 includes a main body 10 and a remote control transmitter 20 that emits a signal for controlling the main body 10 by infrared communication. The remote control transmitter 20 includes a plurality of operation keys. The user controls the main body 10 by selecting and operating this operation key. The remote control transmitter 20 transmits a signal corresponding to each operation key.

  The main body 10 includes a light receiving unit 11 that receives this signal. The light receiving unit 11 converts this signal into an electric signal and transmits it to the control unit 12. The control unit 12 determines which operation key the electric signal is generated by, and controls each component of the main body 10 based on the electric signal. The main body 10 includes a channel selection unit 13, a video processing unit 14, and a display unit 15 in order to receive a television broadcast and output the video and audio. The channel selection unit 13 selects a broadcast radio wave, and the video processing unit 14 demodulates and extracts a video / audio signal from the selected broadcast radio wave. The display unit 15 outputs the video signal with a display and the audio signal with a speaker. For example, a liquid crystal display is used as the display. In addition, a power supply unit 16 that supplies power to the entire main body 10 is provided. Further, in order to output information related to the control of the television receiver 1 to the display unit 15, an OSD (On Screen Display) generation unit 17 that generates a video signal related to this information is provided in the video processing unit 14 and the display unit 15. Prepare in between. The tuning unit 13, the video processing unit 14, the display unit 15, the power supply unit 16, and the OSD generation unit 17 are controlled by the control unit 12. Furthermore, the main body 10 includes a switching unit 18 that switches a mode setting that defines the operation of the control unit 12.

  Note that power supply by the power supply unit 16 can be performed for each component in the main body 10, but power is supplied to all the components described above in order to enable the user to view a TV program. There is a need. On the other hand, in a state where no power is supplied to any component, the user cannot view a television program and cannot receive a signal from the remote control transmitter 20. On the other hand, in a state where power is supplied only to the light receiving unit 11 and the control unit 12 and power is not supplied to other components, it is possible to receive a signal from the remote control transmitter 20. The power supply to other components can be turned ON / OFF by an operation from the remote control transmitter 20. Therefore, hereinafter, it is assumed that the light receiving unit 11 and the control unit 12 are always turned on, and supplying power to other components is referred to as “turning on the power”, and vice versa. Is called “disconnect”. In addition, since the power consumption of the light receiving unit 11 and the control unit 12 is negligibly small compared to the power consumption of the display unit 15 and the video processing unit 14, the power consumption is small even if power is constantly supplied to them. It doesn't matter.

  Here, there is an all-power-on mode as an operation mode that regulates the operation of the control unit 12. As will be described later, when the all-power-on mode is set and the power is not turned on, all the operation keys of the remote control transmitter 20 serve as power-on keys. In other states, when each operation key of the remote control transmitter 20 is operated, the television receiver 1 performs an operation corresponding to each operation key.

  FIG. 2 is a configuration diagram showing the configuration of the remote control transmitter 20. The remote control transmitter 20 includes a plurality of operation keys 21 </ b> A to 21 </ b> Z, a remote control control unit 22, and an infrared output unit 23. Here, the operation keys are 21A to 21Z, but the number is arbitrary. However, it is preferably approximately 20 or less so that the overall size of the remote control transmitter 20 does not increase. The remote controller control unit 22 is connected to the operation keys 21 </ b> A to 21 </ b> Z, and when one of them is operated (pressed), a corresponding signal is generated and output to the infrared output unit 23. The infrared output unit 23 outputs an infrared signal obtained by modulating this signal with infrared light to the outside. Here, the function of the remote controller 22 is only to create a signal corresponding to the operation key, and no other functions are required. Therefore, it is possible to configure the remote control unit 22 with a simple electric circuit, and the configuration of the remote control transmitter 20 is also simple. Therefore, the remote control transmitter 20 can be a small one that is easy for a user to operate with one hand. Further, the remote control transmitter 20 itself is not provided with a power switch, and when the key operation is performed, the remote control control unit 22 and the infrared output unit 23 are temporarily turned on.

  Each operation key in the remote control transmitter 20 is associated with an operation in the main body 10, and the operation name is displayed on each operation key. For this reason, at least the operation | movement of the number of operation keys can be made to respond | correspond. As this operation, for example, “Channel 1 channel selection” to “Channel 12 channel selection” (displayed as “1” to “12”), “Volume increase by one level” (displayed as “volume +”), “Decrease volume by one step” (displayed as “volume-”) can be made to correspond. In addition, “power-on”, “power-off”, “TV input”, “video input”, and the like can be handled. Here, for example, the operations “power on” and “power off” can be performed with one operation key displayed as “power”. In this case, this operation key corresponds to a power-on function when the power is turned off, and corresponds to a power-off function when the power is turned on. Similarly, for "TV input" and "Video input", one operation key is displayed as "TV / video switching", and each time this is operated, the input is switched between TV and video alternately. It can be.

  Here, FIG. 3 is a flowchart showing the operation of the control unit 12 and the like when one operation key (operation key A: 21A) is operated in the remote control transmitter 20. Here, “channel 1 channel selection” is associated with the operation key A. When the operation key A is turned ON in the remote control transmitter 20 (S1), an infrared signal corresponding to the operation key A (21A) (a signal corresponding to the channel 1 channel selection signal) is emitted from the infrared output unit 23. The infrared signal is received by the light receiving unit 11 of the main body 10 (S2). The light receiving unit 11 outputs an electric signal obtained by converting the infrared signal to the control unit 12. Next, the control unit 12 refers to the power supply unit 16 to determine whether or not the power supply of the main body 10 is currently not turned on (S3). If the power is on, the control unit 12 outputs a channel 1 channel selection signal (S11), and ends (S6). When the power is not turned on, the control unit 12 refers to the switching unit 18 to determine whether or not the current mode is the all power on mode (S4). If it is in the all power on mode, a power-on signal is output to the power supply unit 16 (S5), and the process ends (S6). The power supply unit 16 supplies power to components other than the light receiving unit 11 and the control unit 12 in the main body 10 by this signal. Here, when the power is not turned on and in the all power on mode, the channel 1 channel selection signal is not output, and only the power-on signal is output.

  In the above example, the operation of the operation key A (21A) has been described, but the same operation is performed for the other operation keys (B to Z). Further, although “channel 1 channel selection” is associated with the operation key A, the operation associated with each operation key is also arbitrary.

  Therefore, when the all power on mode is set, any operation key is operated, and thereafter the power is turned on. That is, in this case, all the operation keys function as operation keys for turning on the power when the power is not turned on, and no other operation corresponding to each operation key is performed.

  When the power is already turned on (S3) or when the all power on mode is not set (S4), the control unit 12 performs an operation corresponding to the operation key A based on the electric signal input from the light receiving unit 11. The signal for making it output is output to each component (S11). For example, if “channel 1 channel selection” corresponds to the operation key A, a signal for this is output to the channel selection unit 13, and if “one step increase in volume” corresponds, this is displayed on the display unit 15. The signal is output. The channel selection unit 13 and the display unit 15 perform operations corresponding thereto.

  Therefore, when the power is already turned on or when the all power on mode is not set, only the operation corresponding to each operation key is performed. Thus, the user can perform a desired operation on the main body 10 by the remote control transmitter 20. In addition, even when the operation key corresponding to “Channel 1 channel selection” is operated in a state where the power is not turned on and the all power on mode is not set, for example, the power of the tuning unit 13 or the like is not turned on. Therefore, this operation is not actually performed. In this case, only when the operation key corresponding to “power on” is operated, a signal for power on is output and the power is turned on. Thereafter, the user can perform a desired operation other than turning on the power, such as “Channel 1 tuning”, using the remote control transmitter 20.

  The setting as to whether or not the mode is the all power on mode is stored in the nonvolatile memory (memory that is stored and retained even when the power is turned off) of the switching unit 18. For example, a flash memory can be used as this memory. Alternatively, the switching unit 18 may be integrated with the control unit 12 so that the power is always turned on in the case of a power supply method in which the light receiving unit 11 and the control unit 12 are always turned on. The switching of the setting is performed by a key operation on the remote control transmitter 20 or a changeover switch operation on the main body 10. When the operation is performed by key operation, for example, an operation key displayed as “all power on” is provided on the remote control transmitter 20, and when this is operated with the power on, the all power on mode is set. be able to. Alternatively, an operation key displayed as “all power on / normal” may be provided, and each time this operation key is pressed, the state in which the all power on mode is set and the state in which the all power on mode is not set may be switched alternately. . In this case, it is preferable that the OSD generation unit 17 generates “all power on” or “normal” display indicating the current mode on the display unit 15 and causes the display unit 15 to display the display immediately after the setting. Even if these operation keys are not provided, a menu is displayed on the screen of the display unit 15, and the user operates the operation keys of the remote control transmitter 20 or the main body 10 to set the cursor position. You can also. In the case where a changeover switch is provided in the main body 10, any form such as a dip switch can be used.

  When the all-power-on mode is set in the television receiver 1, the power-on operation can be particularly easily performed. For example, even when the room is dark and it is difficult to identify the operation keys, the user can turn on the power by pressing any operation key of the remote control transmitter 20. Thereafter, the user can perform a desired operation on the television receiver 1 by operating each operation key.

  Further, when the user is dark in the room, it is difficult to recognize which operation key is pressed. When the operation key is pressed in this state, the user may be in an unexpected state. For example, when the “TV / video switching” operation key is pressed, there is a case where a video input is made and nothing is displayed on the display unit 15. Similarly, when the “voice OFF” operation key is pressed, no voice is output. When these states occur without the user's recognition immediately after the power is turned on, it is difficult for the user to grasp the state of the television receiver. On the other hand, in the television receiver 1, when the power is not turned on and in the all power on mode, the main body 10 operates to turn on the power regardless of which operation key is pressed. Do only. For this reason, operations other than those expected by the user other than power-on are not performed. Operations other than power-on can be reliably performed after the user recognizes the operation key again after power-on.

  When the all-power-on mode is set, only the above-described operation, that is, the power-on operation is performed regardless of which operation key is pressed, but additional conditions for performing this operation are further set. It may be provided. That is, an additional condition for enabling the all power on mode can be provided. The determination step based on this additional condition can be provided in the same manner as the steps S3 and S4 in the flowchart of FIG. 3, and even when this additional condition is not satisfied, only the operation corresponding to the operation key is performed (S11). can do.

  For example, the main body 10 can be provided with time measuring means, and this additional condition can be set according to the time. For example, the all-power-on mode can be enabled only during the period from 18:00 to 7:00 and disabled during other time periods. In this case, the power can be easily turned on only at night. Further, a timer can be provided in the main body 10 and additional conditions can be set according to various times measured by the timer. For example, the all-power-on mode can be made effective when the power is turned off for a certain time, for example, 8 hours or longer. In addition, the all power-on mode can be made effective when the elapsed time from when the operation was performed immediately before (one of the operation keys was pressed) is longer than a certain time. In these cases, only when the television receiver 1 is not used for a long time, the user can easily turn on the power for the next use. In other cases, the all power on mode is set. Performs the same operation as when it is not set. If the power is turned on once, the power is turned off for zero, or the key operation is performed at that time, so the all power on mode is set for the key operation performed immediately after that. Performs the same operation as when not. That is, when a long time has not elapsed since the power was turned off, or when the elapsed time since the last key operation was short, the user can perform a desired operation with each operation key. .

  In addition, an illuminance sensor is provided in the main body 10, and the all-power-on mode can be validated when the measured illuminance is a constant value, for example, less than 100 lux. Also in this case, when the environment in which the main body 10 is installed is dark, the power-on operation can be easily performed. Since the environment becomes bright after the power is turned on, the all-power-on mode is not effective and an operation corresponding to each operation key is performed.

  Additional conditions can be arbitrarily set in addition to these according to the use mode of the television receiver 1. Further, the all power-on mode can be made effective when a plurality of these additional conditions are satisfied. Further, according to these additional conditions, it is possible to cause the switching unit 18 to determine whether or not to set the all-power-on mode in response to whether or not to enable the all-power-on mode.

  In the television receiver 1, it is the control unit 12 and the switching unit 18 in the main body 10 that perform an operation according to whether or not it is in the all power on mode. At this time, the remote control transmitter 20 may have a simple function of emitting a signal corresponding to each operation key to the light receiving unit 11 regardless of whether or not it is in the all power on mode. Therefore, as shown in the configuration diagram of FIG. 2, the configuration of the remote control transmitter 20 can be simplified. Therefore, a small remote control transmitter can be obtained.

  In the above description, whether or not the all-power-on mode is set is switched by setting, but the all-power-on mode can always be set. That is, in a state where power is supplied only to the light receiving unit 11 and the control unit 12 in the main body 10, it is possible to set to perform only the power-on operation when any operation key is always pressed. Also in this case, according to the determination of S3, it is possible to perform an operation corresponding to each operation key after the power is turned on, and the user can operate the main body 10. In this case, the remote control transmitter 20 does not require an operation key for turning on the power, and only needs to be provided with an operation key for turning off the power.

(Second Embodiment)
The television receiver according to the second embodiment has the same function as the television receiver according to the first embodiment. In other words, the operation is performed according to whether or not it is in the all power on mode, but the configuration for realizing this operation is different from that of the television receiver according to the first embodiment. Particularly, the configuration of the remote control transmitter is different. Here, it is not necessary to provide the switching unit 18 in FIG. In this television receiver, the operation according to whether or not it is the all-power-on mode is realized by the correspondence on the remote control transmitter side.

  FIG. 4 is a configuration diagram of the remote control transmitter 30 in the television receiver according to the second embodiment. The remote control transmitter 30 includes a plurality of operation keys 31A to 31Z, and each operation key corresponds to various operations in the main body. Each operation key is similar to the first embodiment. , Corresponding operation names such as “1”, “volume +”, “power”, and the like are displayed. By operating each of these operation keys, the remote controller control unit 32 creates a signal corresponding to this operation, and the infrared output unit 33 emits an infrared signal obtained by modulating the infrared with this signal. Note that the correspondence between the plurality of operation keys 31A to 31Z and each operation is arbitrary, but the operation keys corresponding to the power-on of the main body are included therein.

  Here, in addition to the plurality of operation keys 31 </ b> A to 31 </ b> Z, the remote control transmitter 30 has an all power on key 34. The remote control control unit 32 includes a microcomputer 35 and a memory 36. Whether or not the television receiver is in the all power on mode is selected by the all power on key 34 and stored in a nonvolatile memory 36. For example, this setting can be set to be alternately selected every time the all power on key 34 is pressed. The microcomputer 35 determines a signal output from the remote control unit 32 in accordance with this setting. Since this remote control transmitter 30 functions only when one of the operation keys is pressed, the power supply of each of the above components is temporarily when any of the plurality of operation keys 31A to 31Z is pressed. Can be set to be input.

  The remote control transmitter 30 further includes a timer 37 and an illuminance sensor 38. The timer 37 measures an elapsed time since any of the plurality of operation keys 31A to 31Z is operated immediately before. That is, the elapsed time is reset every time a key operation is performed. The illuminance sensor 38 measures the illuminance of the environment where the remote control transmitter 30 is placed. The power source of the illuminance sensor 38 can be set to be turned on when any of the plurality of operation keys 31A to 31Z is pressed, similarly to the other components described above. The power supply of the timer 37 needs to be always ON. For this reason, it is preferable that, for example, an ultra-small battery is connected to the timer 37 separately from the power supply of the other components.

  Here, for example, FIG. 5 is a flowchart showing the operation of the microcomputer 35 when the operation key A (31A) is operated. Here, “Channel 1 tuning” is associated with the operation key A. When the operation key A is turned on (S31), the microcomputer 35 connected thereto recognizes this. Next, the microcomputer 35 refers to the memory 36 to determine whether or not the all power on mode is set (S32). If it is the all power on mode, it is determined whether or not the all power on mode is currently valid (S33).

  Here, the determination as to whether or not the all-power-on mode is valid (S33) is a final determination as to whether or not the operation of turning on the power is actually performed regardless of which operation key is used. For this determination, the elapsed time measured by the timer 37 can be used. Thus, if the elapsed time is, for example, 8 hours or longer, the key operation is likely to be an operation immediately after the user returns home, and the all-power-on mode can be validated. Furthermore, the illuminance measured by the illuminance sensor 38 can also be used for this determination. When the room is dark, for example, the illuminance is less than 100 lux, the all-power-on mode can be made effective. That is, the all power on mode can be made effective when the elapsed time is long and the room is dark.

  If it is determined that the all-power-on mode is valid (S33), the remote control unit 32 outputs a power-on signal to the infrared output unit 33 (S34). Here, the operation corresponding to the operation key A is “Channel 1 channel selection”, but this output is not performed, but only the power-on signal is output. Thereby, the infrared output unit 33 emits an infrared signal obtained by modulating the signal for turning on the power, and the process ends (S35).

  On the other hand, when it is not the all power on mode (S32) or when the all power on mode is not effective (S33), the remote controller control unit 32 performs only the operation corresponding to the operation key A (S41), and the process ends ( S35). That is, a signal corresponding to “Channel 1 tuning” is output. In this case, a power-on signal is not issued.

  Further, after it is determined that the all-power-on mode is valid (S33) and a power-on signal is output (S34), the key 37 has been operated once, so the elapsed time in the timer 37 is reset. . For this reason, when the operation key A is operated again immediately after that, it is determined that the all power on mode is not effective (S33). Therefore, the remote control unit 32 performs only the channel 1 channel selection operation (S41). As a result, the user can perform the “channel 1 channel selection” operation. The same applies to the subsequent operations.

  Although the operation of the operation key A (21A) has been described in the above example, the same operation is performed for the other operation keys (B to Z). Further, although “channel 1 channel selection” is associated with the operation key A, the operation associated with each operation key is also arbitrary. That is, when the all power on mode is set and the all power on mode is valid, a power-on signal is transmitted from the remote control transmitter 30 regardless of which operation key is operated, and thereafter The power is turned on. That is, in this case, all the operation keys function as operation keys for turning on the power when the power is not turned on, and no other operation corresponding to each operation key is performed. Further, when the all power on mode is not set or the all power on mode is not effective, the remote control transmitter 30 transmits a signal for performing an operation corresponding to each operation key.

  Note that it is also possible to use only the illuminance measured by the illuminance sensor 38 without using the timer 37 to determine whether or not the all-power-on mode is valid. In this case, when the all-power-on mode is set, the remote control transmitter 30 can always be turned on only when the room is dark. However, especially when the display of the television receiver is large, the room becomes brighter after the power is turned on, so the room automatically becomes brighter. For this reason, after the power is turned on, the all-power-on mode becomes invalid, and thereafter, the operation corresponding to each operation key is performed (S41).

  Also in this television receiver, when the all power on mode is set and the all power on mode is enabled, the power is turned on regardless of which operation key is operated, and other than those corresponding to the operation keys. Is not performed at all.

  In this television receiver, the microcomputer 35 determines whether or not it is in the all power on mode (S32). A signal for turning on the power (S 34) and an operation signal (S 41) corresponding to each operation key are created by the remote control unit 32, and an infrared signal obtained by modulating this with infrared rays is emitted by the infrared output unit 33. That is, only the remote control transmitter 30 operates differently depending on the setting as to whether or not the mode is the all power on mode.

  In this case, the signal for turning on the power of the main body is the remote control when either the operation key corresponding to the power on is pressed or when any operation key is pressed in the all power on mode. It is emitted from the transmitter 30. In either case, since the same signal (power-on signal) is generated, the main body does not need to recognize whether or not the current mode is the all power on mode. Therefore, the control unit of the main body always performs only the operation according to the signal input by the infrared signal.

  Also in the television receiver using the remote control transmitter 30, as in the television receiver according to the first embodiment, when the all power on mode is set, the power-on operation is particularly performed. It can be done easily. For example, even when the room is dark and it is difficult to identify the operation key, the user can turn on the power by pressing any operation key of the remote control transmitter 30. Thereafter, the user can perform a desired operation in the television receiver by operating each operation key.

  Similarly to the television receiver according to the first embodiment, when the power is turned on in the all power on mode, no operation other than the power on is performed. For this reason, an operation unexpected by the user is not performed.

  In the second embodiment, the illuminance sensor 37 and the timer 38 are provided. However, as described above, the same effect can be obtained even if any one of them is provided.

  In this remote control transmitter 30, it is preferable that the all power on mode is set so that it can be easily canceled. For example, the all power on mode can be set to be released by pressing the all power on key 34 again. An operation key for canceling the all power on mode may be provided separately. Whether or not the current mode is the all power on mode is preferably displayed on a part of the remote control transmitter 30.

  In this television receiver, the remote control transmitter 30 performs the above operation regardless of the power state of the main body, and the signal is always transmitted from the remote control transmitter 30 to the main body. For this reason, the remote control transmitter 30 cannot obtain information about whether or not the main body is actually turned on. The main body and the remote control transmitter 30 can communicate with each other, and information for this can be obtained from the main body. For example, the remote control transmitter 30 is provided with not only the infrared output unit 33 but also an infrared light receiving unit, and at the same time, the main body and the remote control transmitter 30 can perform infrared communication with each other. In this case, in the flowchart of FIG. 5, instead of determining whether or not the all-power-on mode is valid (S33), the power source is the same as S3 in the flowchart (FIG. 3) in the first embodiment. The microcomputer 35 can also determine whether or not it is not inserted.

  In this case, when any one of the operation keys of the remote control transmitter 30 is pressed, the infrared output unit 33 first transmits a signal for transmitting the power status of the main body to the main body, and an answer to this is sent from the remote control. The operation of the flowchart of FIG. 5 (S32 and subsequent steps) can be performed after the transmitter 30 receives the information indicating whether the power is not turned on.

  In the case of the television receiver according to the second embodiment, the remote control transmitter 30 performs all operations according to the mode setting. For this reason, this television receiver can be realized only by changing the remote control transmitter without changing the main body, which is particularly expensive in the conventional television receiver. Therefore, this television receiver can be obtained at low cost.

  For example, when the illuminance measured by the illuminance sensor 38 is used, the all-power-on mode is enabled according to the environment of the remote control transmitter 30. That is, the power can be easily turned on according to the environment of the remote control transmitter at hand of the user.

  Although both the first and second embodiments have been described with respect to the case of a television receiver, the present invention is not limited to this, and may be applied to other electric devices operated using a remote control transmitter. The same applies. For example, an air conditioner, a video deck, a DVD player, or the like is installed indoors, and the main body thereof can be particularly preferably used for a large electric device. Further, the present invention can be similarly applied to other electric devices used not in the room but in the automobile, such as a car navigation system. Moreover, although the case where the remote control transmitter and the main body are connected by infrared communication has been described, the present invention can be similarly applied to other connection methods, for example, a wired connection.
