Description

  The present invention relates to a remote controller for controlling a controlled apparatus and a light emission control method for the remote controller.

  Conventionally, a television receiver or a remote controller that can operate a plurality of electronic devices such as a television receiver and an external AV device has been proposed. The remote controller is controlled by a communication method such as infrared communication (hereinafter appropriately referred to as IR (Infrared) communication) or wireless communication (hereinafter appropriately referred to as RF (Radio Frequency) communication) according to a user operation. Send the signal to the electronic device. In the electronic device, control such as channel selection and volume adjustment is performed according to the received control signal.

  By the way, in recent years, a device such as a home theater is used, and a remote controller may be operated in a dark room. In order to improve operability in a dark environment and prevent erroneous operation, a remote controller configured to emit operation key portions such as a numeric keypad and a volume adjustment key as described in Patent Document 1 has been proposed. .

JP 2006-340263 A

  Such a remote controller has, for example, an operation key sheet in which a plurality of operation keys are integrally provided and a circuit board having an LED (Light Emitting Diode) in a case made by resin molding. The circuit board is provided below the operation key sheet, and a plurality of LEDs are arranged on the operation key sheet side of the circuit board. Each operation key portion of the operation key sheet is exposed from the case of the remote controller and can be pressed. The operation key sheet is made of a light transmissive material, and each operation key of the remote controller emits light when the irradiation light emitted from the LED passes through the operation key sheet.

  Patent Document 1 describes that an operation key is not allowed to always emit light, but an operation key is caused to emit light for a predetermined time when the remote controller is used. For example, the LED is made to emit light for a predetermined time after the user presses an arbitrary operation key, and then the LED is automatically turned off.

  In the case of the configuration of the remote controller of Patent Document 1, for example, as shown in FIG. 1, when an arbitrary operation key is pressed, the LED emits light and the illumination is turned on. When the depression of the operation key is released, counting of a predetermined automatic turn-off time T is started by an automatic turn-off timer or the like. If any operation key is pressed before the automatic turn-off time T is counted, the automatic turn-off timer is reset, and when the operation key is released, the automatic turn-off timer again sets the automatic turn-off time T from 0. Count. When the automatic turn-off timer counts the automatic turn-off time T, the illumination is turned off.

  In FIG. 1, the automatic extinguishing timer is started by detecting the falling edge of the light key or the operation key. The automatic turn-off timer is reset by detecting the rising edge of the operation key.

  There is also a method of providing a light key for performing light-up so that the LED is turned on when the light key is operated.

  In such a configuration, the LED is turned on when the light key is pressed. The light is turned off after a predetermined automatic turn-off time T after the light key is released.

  Further, as shown in FIG. 2, the illumination may be turned on when the light key is operated, and the illumination may be continued while any operation key is operated. Also in this case, the illumination may be turned off when a predetermined automatic turn-off time T elapses after the light key or any operation key is released. In this case, when the operation key is operated without operating the light key, the illumination is not turned on.

  The lighting method shown in FIG. 2 will be described in detail with reference to the flowchart of FIG. In the flowchart of FIG. 3, keys that can be operated including the write key are referred to as operation keys. In the flowchart, “operation key ON” indicates that the operation key is pressed, and “operation key OFF” indicates that the operation key is released.

  First, when the operation key is pressed in step S1, it is determined whether or not the operation key operated in step S2 is a light key. If the operation key is not a light key, a control signal is transmitted according to the operated operation key as in step S11 to control a controlled device such as a television receiver.

  If the operated key is a light key, it is determined in step S3 whether or not the illumination has been turned on. If the illumination is not turned on, the LED is turned on in step S4, and the LED illumination is turned on. If the illumination is on, the light key is operated while the LED illumination is on, and the illumination is turned off by this operation, so the LED illumination is turned off in step S8.

  After the LED illumination is turned on, when the operation key (light key) is released in step S5, the automatic turn-off timer is turned on. In step S6, it is determined whether or not a preset automatic extinguishing time T has elapsed. If it is determined that the automatic turn-off time T has elapsed, the automatic turn-off timer is turned off in step S7, the LED illumination is turned off in step S8, and the process ends.

  If it is determined in step S6 that the automatic turn-off time T has not elapsed and any of the operation keys including the light key is turned on in step S12, the operation key operated in step S13 is the light key. It is determined whether or not. When it is determined that the operation key operated in step S13 is a light key, the light key is operated while the LED illumination is on. For this reason, even if the automatic turn-off time T has not elapsed, the automatic turn-off timer is turned off in step S7, the LED illumination is turned off in step S8, and the process ends.

  If it is determined that the operation key operated in step S13 is not a light key, that is, if a key for operating a television receiver or the like such as a numeric keypad is pressed, the automatic turn-off timer is reset in step S14. . In addition, a control signal corresponding to the operated operation key is transmitted to a television receiver or the like.

  Then, the process returns to step S5, and when the operated operation key is turned off, the automatic extinguishing timer is turned on again, and the automatic extinguishing time T is counted again. Then, when the operation key is not operated during the automatic turn-off time T thereafter, the LED illumination is turned off.

  However, if the user causes the LED to emit light for a predetermined time after pressing any operation key, the LED emits light even when the surroundings are bright and the operation key does not need to be emitted, and the battery is wasted. . Further, when the LED is allowed to emit light for a predetermined time by the light key, the LED may be turned off before the operation of the operation key is completed, and the operability is deteriorated.

  Further, in the case of the light-up method as shown in FIG. 2 and FIG. 3, when the operation key is operated immediately after the light is turned off, the operation key is not lighted up. Must be pressed. For this reason, it will increase the effort of operation. Moreover, if the automatic light extinction time T is lengthened in order to solve this, the lighting time of the LED becomes long and the power consumption increases.

  Accordingly, an object of the present invention is to provide a remote controller that suppresses power consumption and has excellent operability, and a light emission control method for the remote controller.

  In order to solve the above-described problem, the first invention includes an operation unit having a plurality of operation keys for performing remote control, an operation key for light emission, and a communication unit capable of transmitting a control signal to a controlled device. A light-emitting unit that causes the operation unit to emit light, a first timer that counts a first time, and a second timer that counts a second time, and an operation signal from the operation unit is input A control unit that controls the communication unit and the light emitting unit. When an operation signal of the operation key for light emission is input, the control unit controls the light emitting unit to emit light, and the operation unit emits light. When the operation key operation signal is not input for the first time, the operation unit stops emitting light, and after the operation unit stops emitting light, the operation key operation signal remains within the second time period. This is a remote controller that causes the operation unit to emit light when it is input to.

  In the above-described remote controller, when the control unit detects an operation signal of the operation key or the operation key for light emission, the control unit causes the first timer to start counting the first time to cause the operation unit to emit light. At the end of the counting of the first time by the timer, the light emission of the operation unit is stopped and the second timer is started to count the second time.

  In the remote controller described above, when the control unit detects the operation signal of the operation key while the first timer is counting the first time, the control unit resets the first timer and sets the first timer to the first timer. When the first timer detects the operation signal of the operation key for light emission while counting the first time, the first timer is started. Stop and stop the light emission of the operation unit.

  In the remote controller described above, when the control unit detects an operation signal of the operation key when the second timer is not counting the second time, the control unit controls the light emitting unit so that the operation unit does not emit light. .

  In the remote controller described above, the control unit may set the first time and the second time depending on the operation state of the operation keys. Further, the first time and the second time may be settable by the user.

  According to a second aspect of the present invention, there is provided a first detection step for detecting an operation signal for the light emission operation key, a first light emission step for turning on the light emitting portion when the operation signal for the light emission operation key is detected, A first counting step for causing the first timer to start counting the first time when an operation signal for the operation key is detected, and no operation signal for the operation key is input during the first time counting In this case, the light emission stop step for stopping the light emission of the operation unit and the light emission of the operation unit are stopped at the end of the first time count by the first timer, and the second timer counts the second time. Remote controller having a second counting step for starting the operation and a second light emitting step for causing the operation unit to emit light when an operation signal of the operation key is input during counting of the second time A light emission control method.

  In the above-described light emission control method of the remote controller, when the first timer detects the operation signal of the operation key while counting the first time, the first timer is reset and the first timer is set to the first timer. It further includes a reset step of restarting the counting of the time of 1 and continuing the light emission of the operation unit. Further, when the first timer detects the operation signal of the operation key for light emission while counting the first time, it further includes a stop step of stopping the light emission of the operation unit by stopping the first timer. Like that.

  In the present invention, when the operation key is operated without operating the light emission operation key, it is possible to prevent the operation key from being lighted up. Further, when the operation key for light emission is operated, the entire operation key and the operation key for light emission are lighted up, and when the operation key is operated within a certain interval, the light-up can be continued. Furthermore, even when the operation key is not operated for a certain time and the light-up is stopped, the light-up can be performed even if the operation key for light emission is not operated when the operation key is operated within a certain time thereafter. it can.

  In the present invention, the operation key is lit up while the first timer is counting the first time. Then, counting of the first time by the first timer ends, and the second timer counts the second time while the light-up is turned off. During the counting of the second time, the light-up is performed even if the operation key for light emission is not operated.

  According to the present invention, when it is not necessary to light up the operation keys of the remote controller, it is possible to prevent the light from being lighted up, and thus it is possible to suppress power consumption. Further, when the operation key is operated within a certain time after the light-up is stopped, the light-up can be performed without the operation of the light emission operation key.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  In one embodiment of the present invention, each operation key including the light key is lighted up by operating the light key, and there is no operation of each operation key during the automatic turn-off time T1 after the operation key is operated. Causes the LED to be turned off. When the operation key is operated within the time T2 after the light is turned off after the light-up is completed, the operation key is lighted up even if the light key is not pressed.

  In the present invention, the light key is operated to light up the operation key when used in a dark environment, and the operation key is operated without operating the light key when used in a bright environment. . Thereby, in a dark environment, each operation key is lighted up and the operability is improved. When it is not necessary to light up each operation key, a control signal can be transmitted without wasting power by operating an operation key such as a numeric keypad without operating the light key.

  Further, when the operation key is operated within the automatic turn-off time T1 after the light-up is completed, the operation key is lighted up, so that the operability is improved. Further, with such a configuration, it is not necessary to set the post-extinguishment time T2 to a time longer than necessary, so that wasteful power consumption can be further suppressed.

  The configuration of the remote controller will be described below.

[Remote controller configuration]
A first embodiment of the present invention will be described with reference to FIG. The remote controller 10 controls, for example, the television receiver 1 that is a controlled device, and includes an operation unit 10a provided with a plurality of operation keys. The operation unit 10 a includes an operation key for controlling the television receiver 1 and a light key 13 for illuminating the operation key of the remote controller 10. The remote controller 10 is schematic and a more specific configuration will be described later.

  The television receiver 1 is provided with a receiving unit for receiving a control signal transmitted from the remote controller 10. The receiving unit can receive a control signal in accordance with a communication method between the remote controller 10 and the television receiver 1.

  The configuration of the remote controller 10 will be described in further detail. FIG. 5 shows an example of the external appearance of the configuration of the remote controller 10. The illustrated remote controller 10 includes an operation unit 10a including a light key 13 and a plurality of other operation keys provided on the surface of the housing, a communication unit 11 that transmits and receives control signals, and a shutter 18 that can be opened and closed by sliding, for example. It has. Although not shown, a plurality of operation keys are also arranged inside the shutter 18.

  The operation unit 10a includes a power on / off button 12, a light key 13, a numeric key 14, a determination button 15, a direction button 16, a volume up / down button 17a, a channel up / down button 17b, and the like. Further, an external device operation key 19 may be provided. The light key 13 is used to light up each machine key of the operation unit 10a, and an LED (not shown) is turned on when the light key 13 is pressed.

  FIG. 6 is an exploded perspective view of the remote controller 10. For example, a light guide plate 23 is provided in a gap between the operation key sheet 21 and the circuit board 22 formed by integrally molding a plurality of operation keys. These are housed in a case 24 composed of an upper case 24a and a lower case 25b to form the remote controller 10. In the remote controller 10, for example, five LEDs 25 a, 25 b... 25 e are provided on the operation key sheet 21 side of the circuit board 22. When the LEDs 25a, 25b,... 25e are turned on, the irradiation light from the LEDs 25a, 25b,... 25e is diffused through the light guide plate 23, and the plurality of operation keys 21a are lit up.

  FIG. 7 shows a configuration example of a main part of the remote controller 10. The remote controller 10 includes a key matrix 31, a control unit 32, LEDs that are the communication unit 11, and LEDs 25a to 25e that light up the entire remote controller 10.

  The key matrix 31 detects which operation key is pressed in the operation unit 10 a included in the remote controller 10, and supplies a detection signal indicating the detection result to the control unit 32. All the operation keys provided in the operation unit 10a are included in the key matrix 31.

  The control unit 32 is a microcomputer (hereinafter appropriately referred to as MPU) including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a memory, and the like (not shown). The control unit 32 controls each unit of the remote controller 10 using the RAM as a work memory when executing the program according to a program stored in advance in the ROM. The memory is a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable ROM), and stores operation commands corresponding to the operation keys of the operation unit 10a, setting information of the remote controller 10, and the like. Based on the operation signal supplied from the key matrix 31, the control unit 32 reads an operation command corresponding to the detected address of the operation key from the memory and supplies the operation command to the communication unit 11. When it is detected that any one of the operation keys has been operated, the LEDs 25a to 25e are turned on when the conditions are met.

  The communication unit 11 performs infrared transmission by turning on / off the LED of the infrared light emitting unit with respect to the television receiver 1. The communication unit 11 transmits various data such as operation commands supplied from the control unit 32 to the television receiver 1.

  In the remote controller 10, for example, the LEDs 25a to 25e are arranged on a circuit board provided at a lower portion of an operation key sheet in which a plurality of operation keys are provided integrally. In FIG. 7, five LEDs 25a to 25e are provided for lighting the operation keys. However, the present invention is not limited to this, and any number of LEDs can be used. The operation key sheet is made of a light-transmitting material, and each operation key of the remote controller 10 emits light when the irradiation light emitted from the LEDs 25a to 25e passes through the operation key sheet. Each operation key portion of the operation key sheet is exposed to the outside from the case of the remote controller 10 and can be pressed.

  The LEDs 25a to 25e are turned on based on the operation command supplied from the control unit 32. Further, the LEDs 25a to 25e are controlled to be turned off when a set time has elapsed after the start of lighting. Hereinafter, a method for lighting up each operation key will be described in detail.

[Light-up method of remote controller]
FIGS. 8 and 9 show the operation timing of the light key 13 and one operation key, the illumination processing timing of the LEDs 25a to 25e, and the illumination timing in an embodiment of the present invention.

  In the present application, when each operation key (excluding the light key 13) included in the operation unit 10a is operated without operating the light key 13, the operation key is not lighted up. Therefore, in FIGS. 8 and 9, only the case where the write key 13 is first operated to light up each operation key will be described. 8 and 9, the operation key indicates an operation key other than the light key 13.

  In FIG. 8, the light key 13 is first pressed. Then, illumination (LED25a thru | or 25e) lights. Then, if any of the operation keys is operated, and the operation key is not operated within the automatic turn-off time T1 after the operation key is released, the illumination is turned off. The operation key is continuously lit regardless of which operation key is operated.

  When the operation key is operated again within the time T2 after the illumination is turned off, the light is turned on even if the light key 13 is not operated in advance.

  Lighting off and relighting after the lighting is turned off are controlled by the control unit 32 based on the turn-off timer and the post-light-off timer. The extinguishing timer and the timer after extinguishing are built in the MPU of the control unit 32 and count a predetermined time. When the light key 13 is pressed, a waveform indicating the state of the light key 13 rises, and when the light key 13 is released, the waveform falls. Similarly, when another operation key, for example, the “1” key of the numeric keypad is pressed, a waveform indicating the state of the “1” key rises, and when the “1” key is released, the waveform falls. .

  First, when the light key 13 is pressed, the rising edge of the light key 13 is detected by the MPU, and the illumination is turned on. When the pressing of the light key 13 is released and the falling edge of the light key 13 is detected by the MPU, counting of the extinguishing timer which is the first timer is started. If any of the operation keys is operated before the automatic extinguishing time T1 is counted in the extinguishing timer and the rising edge of the operating key is detected by the MPU, the extinguishing timer count is reset.

  If there is no operation key operation before the turn-off timer counts the automatic turn-off time T1, the illumination is turned off when the turn-off timer counts the automatic turn-off time T1.

  When the illumination timer counts the automatic extinguishing time T1 and detects that the illumination is extinguished, the after-extinguishing timer T2, which is the second timer, starts counting the after-extinguishing time T2. If the operation key is pressed again until the timer T counts the time T2 after the light is turned off and the MPU detects the rising edge of the operation key, the timer is reset after the light is turned off and the illumination is turned on again. The When the operation key is released and the MPU detects a falling edge of the operation key, counting by the extinguishing timer is started.

  On the other hand, as shown in FIG. 9, when the operation key is not operated while the timer after extinguishing counts the time T2 after extinguishing, the illumination is not turned on even if the operation key is operated after the time T2 after extinguishing. In the present invention, only when the operation key is operated while the timer after turning off is counting the time T2 after turning off, the lighting is turned on again without operating the light key. 8 and 9, when an operation key is operated, a control signal corresponding to the operated operation key is transmitted from the control unit 21 to the television receiver 1 or the like.

  If the light key 13 is operated while the illumination is on, the illumination is turned off. In this case, the illumination may be turned off when the rising edge of the light key 13 is detected by the MPU, or may be turned off when the falling edge of the light key is detected. When the operation key is operated without operating the light key 13 after the illumination is turned off, the control signal is transmitted without turning on the illumination again. Further, when the light key 13 is operated again after the illumination is turned off, the illumination is turned on again and counting is started in the turn-off timer.

  The automatic turn-off time T1 and the post-light-off time T2 can be changed according to user settings. By displaying a predetermined setting screen or the like and operating the numeric keypad 14 or the direction button 16, it is possible to set a desired automatic turn-off time T1 and a turn-off time T2 in units of seconds or minutes.

  The flow of such a light-up process will be described with reference to the flowchart of FIG. In FIG. 10, the operation keys are described including the light key. In the flowchart of FIG. 9, “operation key ON” indicates that the operation key is pressed, and “operation key OFF” indicates that the operation key is released.

  First, when the operation key is turned on in step S21, it is determined whether or not the operation key operated in step S22 is a light key. If the operation key is not a light key, a control signal corresponding to the operated operation key is transmitted as in step S41.

  If the operated operation key is a light key, it is determined in step S23 whether or not the illumination has been turned on. If the illumination is not turned on, the LED is turned on in step S24, and the LED illumination is turned on. If the illumination is on, the LED illumination is turned off in step S28.

  When the depression of the operation key (in this case, the light key) is released after the LED illumination is turned on, the automatic turn-off timer is turned on in step S25. Then, in step S26, it is determined whether or not a preset automatic turn-off time T1 has elapsed. If it is determined that the automatic turn-off time T1 has elapsed, the automatic turn-off timer is turned off in step S27, the LED illumination is turned off in step S28, and the process ends.

  If it is determined in step S26 that the automatic turn-off time T1 has not elapsed and any of the operation keys including the light key is turned on in step S42, the operation key operated in step S23 is the light key. It is determined whether or not. If it is determined in step S43 that the operated operation key is a light key, the light key is operated while the LED illumination is on, so the automatic turn-off timer is turned off in step S27, and the LED illumination is performed in step S28. Is turned off.

  When it is determined that the operation key operated in step S43 is not a light key, a control signal corresponding to the operation key operated in step S44 is transmitted. In step S45, the automatic turn-off timer is reset. In addition, a control signal corresponding to the operated operation key is transmitted to a television receiver or the like.

  Then, the process returns to step S25, and when the operated operation key is turned off, the automatic turn-off timer is turned on again, and the automatic turn-off time T1 is recounted. If the operation key is not operated during the automatic turn-off time T1, the automatic turn-off timer is turned off in step S27, and the LED illumination is turned off in step S28.

  When the LED illumination is turned off in step S28, the timer is turned on after the light is turned off in step S29. If it is determined in step S30 that the time T2 after turning off has not elapsed, it is determined in step S46 whether or not the operation key is turned on. If it is determined in step S46 that the operation key has not been operated, the process returns to step S30. If it is determined in step S46 that the operation key has been turned ON, the timer is reset after the light is turned off in step S47, and the process returns to step S24, and the LED illumination is turned ON again. In step S46, the same processing is performed regardless of which of the light key and the operation key is operated.

  On the other hand, if it is determined in step S30 that the time T2 after turning off has elapsed, the automatic turn-off timer is turned off in step S31, and the process ends.

  As described above, when a light key is operated before operating an operation key such as a numeric keypad, each operation key is turned on. When there is no operation of the light key, each operation key is not turned on. When each operation key is lit, lighting is continued when the operation key is operated within a predetermined operation interval, and illumination is turned on when there is no operation key operation for a certain period of time after the operation key is operated. Turn off the light. If the operation key is operated within a predetermined time after the illumination is turned off, the illumination is turned on again without operating the light key. If the operation key is not operated within a predetermined time after the illumination is turned off, the illumination is not turned on unless the light key is operated in the subsequent operation.

  With such a configuration, when there is no need to illuminate the remote controller 10, the operation key is used to illuminate unnecessarily, thereby suppressing power consumption. In addition, when the light up is necessary, the light is turned on by operating the light key. When the operation key is operated within a predetermined time after the illumination is turned off, the light is automatically turned on again. There is no loss of operability.

  Although one embodiment of the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and various modifications based on the technical idea of the present invention are possible.

  For example, in the above description, the LEDs 25a to 25e are described as being collectively lit. However, a plurality of areas such as an operation unit including a numeric keypad 14 part, a determination button 15 and a direction button 16, and an external device operation key 19 part are provided. May be individually lit up. That is, when the numeric keypad 14 is operated, only the numeric keypad 14 portion is lit up. Thereby, power consumption can be further reduced. Of course, the number of installed LEDs can be arbitrarily determined.

  Further, the lighting time can be set differently for each area.

  Further, the automatic turn-off time T1 and the post-light-off time T2 may be set automatically by the remote controller 10 instead of being set by the user. The operation of the user's operation key can be detected by the MPU by detecting the rising edge and the falling edge. For this reason, for example, the number of times that the user operates the operation key within a certain time, the operation interval, and the like may be statistically set so that the automatic turn-off time T1 and the turn-off time T2 suitable for the user can be automatically set.

  In addition, the communication unit 11 uses an LED and is configured to transmit a control signal by IR communication. However, the control signal may be transmitted by RF communication.

  Furthermore, the timing at which the automatic extinguishing timer and the timer after extinguishing start and the reset of the count are started are not limited to the above timing. For example, the counting may be started when the operation key is pressed.
