2. Description of the Related Art In order to be able to comfortably fall asleep, a conventional technique of gradually reducing the volume when a timer is performing a time-measuring operation toward a power-off state is as follows.
JP-A-53-145541 (hereinafter referred to as a first prior art), JP-A-61-163427 (hereinafter referred to as a second prior art), and JP-A-7-212154 (referred to as a third prior art). ). Further, in the second and third conventional techniques, a technique for gradually increasing the volume when the power is turned on by a timer,
It is also disclosed. Further, the third prior art also discloses that when the power is turned on by a timer, the volume is increased beyond a value set by a user.

[0003]

However, when the above technique is applied to, for example, a television or a radio, the following problems have occurred. In other words, when the broadcast received at the time of waking up is news, a situation often occurs in which the content of the broadcast contains anxious content while the volume is increasing. However, even when such a situation occurs, in the second and third prior arts, the sound volume only increases at a predetermined rate. As a result, during the period until the sound volume increases to a sufficient value, there is a possibility that the broadcast contents may be missed. In addition, there is a problem that the television or the radio is left in the operation mode when the user is out of the office even though the power is automatically turned on by the timer.

[0004] In addition, in the case where the user does not fall asleep during the operation of the sleep timer and the user continues to watch the broadcast by changing the channel, the time when the channel is changed is close to the end time of the timer operation of the timer. In some cases, the volume was low and the broadcast content was difficult to hear. In addition, the power may be turned off in a short time after changing the channel. For this reason, after releasing the timer setting once,
A complicated operation of setting the timer again has been required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. It is an object of the present invention to set the volume to a value set by a user when the input means is operated while the volume is increasing. An object of the present invention is to provide an electronic device which can immediately change the sound volume to a level that is easy to hear even when the volume is at a level that is difficult to hear.

In addition to the above objects, when the volume is increased to the upper limit, the operation mode is shifted to the standby mode when no operation is input to the input means, and automatically when the absence is performed. An electronic device capable of shifting to a standby mode is provided.

Another object of the present invention is to listen to the volume by operating the input means while the volume is being reduced, by returning the volume to a value set by the user and then restarting the reduction of the volume. It is an object of the present invention to provide an electronic device that can eliminate an input operation for reducing the volume even when the volume is returned to an easy volume.

In addition to the above object, there is provided an electronic apparatus capable of easily restarting the timer operation by initializing the operation of the timer means and the operation of reducing the volume when an operation is input to the input means. To provide.

In addition to the above object, when the sound volume is being reduced even when the time counting by the timer means is completed, the timing of shifting the operation mode to the standby mode is delayed until the sound volume is reduced to a predetermined value. By
It is an object of the present invention to provide an electronic device capable of shifting to a standby mode when the sound volume is sufficiently reduced even when the input means is operated near the end of time counting by the timer means.

[0010]

In order to solve the above-mentioned problems, an electronic device according to the present invention has a sound circuit whose output value can be controlled and a sound volume storage for storing a sound volume corresponding value corresponding to a sound volume set by a user. Means, timer means for shifting the standby mode to the operation mode when a preset time is reached, input means for inputting an operation instruction, and output of the audio circuit when the mode is shifted from the standby mode to the operation mode. The present invention is applied to an electronic device including a volume increasing unit that gradually increases a value, and the volume increasing unit gradually increases the output value of the audio circuit, and when an operation is input to the input unit, The output value of the audio circuit is set to the sound volume corresponding value stored in the sound volume storage means.

That is, the sound volume corresponding value stored in the sound volume storage means is a value indicating a sound volume that is easy for the user to hear. Therefore, when the volume increase means gradually increases the output value of the audio circuit, when an operation is input to the input means, the volume immediately changes to a volume that is easy to hear.

In addition to the above configuration, even when the volume increasing means increases the output value of the audio circuit to a preset upper limit value, when no operation is input to the input means, the operation mode is changed. Control means for shifting to the standby mode is provided.

That is, when the preset upper limit value of the volume-corresponding value is set to a value corresponding to a volume that is perceived to be loud to the user, the user operates the input means before the volume increases to the upper limit value. Will be entered. Therefore, the time when the sound volume increasing means increases the sound volume corresponding value to the preset upper limit value is when the user is away. For this reason, when the user is away, the mode automatically shifts to the standby mode.

The electronic device according to the present invention is provided with an audio circuit capable of controlling an output value, volume storage means for storing a volume corresponding value corresponding to a volume set by a user, and an instruction to start timing. When the timer starts counting time for a predetermined period of time, and after the time measurement ends, the timer means shifts the operation mode to the standby mode, input means for inputting an operation instruction, and audio The present invention is applied to an electronic device including a sound volume reducing unit that gradually reduces an output value of a circuit, and the volume reducing unit is configured to gradually reduce an output value of an audio circuit when an operation is input to an input unit. In this method, the output value of the audio circuit is restored to the value corresponding to the sound volume stored in the sound volume storage means, and then gradually reduced.

That is, only by inputting an operation to the input means, the volume is gradually reduced after returning to the easy-to-hear volume set by the user.

Further, in addition to the above configuration, the timer means restarts the time measurement for the predetermined period when an operation is input to the input means while the time measurement is being performed, and the volume reduction means comprises: The output value of the audio circuit is gradually reduced in response to the restart of the time counting by the timer means.

That is, the operation of the timer means and the operation of the volume reduction means are resumed only by inputting an operation to the input means.

Further, in addition to the above configuration, the timer means shifts the operation mode to the standby mode even when the clocking of the predetermined period ends, when the output value of the audio circuit has not decreased to the predetermined value. The timing of the delay is delayed until the voice reduction unit reduces the output value of the voice circuit to a predetermined value.

That is, when the time period ends,
When the volume is high, the operation mode is continued. Then, when the volume becomes low, the standby mode is set.

The block 13 including the input unit 6 and the remote controller 7 corresponds to an input unit described in claims.

The memory 8 is a block composed of an EEPROM, and stores various values set by the user. That is, the reception channel immediately before shifting to the standby mode is stored. Also, when in the operation mode, a volume corresponding value corresponding to the volume set by the user is stored. Further, other setting values set by the user are stored. That is, the memory 8 constitutes a sound volume storage unit as a part of the function.

The control unit 5 is a block constituted by a microcomputer, and controls main operations as a television. When the preset time comes, the operation of the power supply unit 4 is started,
Timer means for shifting the standby mode to the operation mode is configured. Further, when the mode shifts from the standby mode to the operation mode, a volume increasing means for gradually increasing the output value of the audio circuit 2 is provided.

When the output value of the audio circuit 2 is gradually increased when the volume is increased, and when an operation is input to the input unit 13, the output value of the audio circuit 2 is stored in the volume storage. The volume is set to the value corresponding to the volume stored in the means 8.

Even when the output value of the audio circuit 2 is increased to a preset upper limit value, when no operation is input to the input means 13, the operation of the power supply unit 4 is stopped, thereby setting the operation mode. The control means for shifting to the standby mode is configured.

When a user gives an instruction to start timekeeping (instruction to start operation of a sleep timer) via the input means 13, the control unit 5 starts timekeeping for a predetermined period, and starts timekeeping. When the operation is completed, timer means for stopping the operation of the power supply unit 4 to shift the operation mode to the standby mode is configured.

FIG. 1 is a flowchart showing the main operation of the first embodiment when operating as a wake-up timer, FIG. 2 is a flowchart showing the main operation of the first embodiment when operating as a sleep timer, FIG.
Is an explanatory diagram showing the volume change at the time of the wake-up timer,
FIG. 6 is an explanatory diagram showing a change in volume at the time of the sleep timer. The operation of the embodiment will be described with reference to these drawings as necessary.

When the preset wake-up time comes, the control section 5 operates the power supply section 4 to set the television circuit 1 and the audio circuit 2 to the operation mode (steps S1 and S2). Further, the output value of the audio circuit 2 is set to the initial value L1 shown in FIG. 5 (step S1).
3). Then, it is determined whether or not an operation has been input to the remote controller 7 or the input unit 6 (input means 13) (step S4). And if no operation is entered,
It is checked whether 10 seconds have elapsed (step S5).
If 10 seconds have not elapsed, steps S4 and S5
Is repeated.

When the operation of steps S4 and S5 is repeated for 10 seconds, it is checked whether the output value set in the audio circuit 2 has reached the upper limit L3 (step S6). In this case, since it is not the upper limit L3,
The output value of the audio circuit 2 is increased by one stage (step S
7). Then, the operation returns to the operation of step S4. Therefore,
When the output value of the audio circuit 2 is smaller than the upper limit L3 and no operation is input to the input unit 13, the above-described loop operation is executed. As a result, the volume increases by one step every 10 seconds.

Then, it is assumed that the user who wakes up at the time of low volume operates the channel key of the remote controller 7 at time T1, for example, to receive the channel which is always watched in the morning. In this case, the control unit 5 shifts the operation from step S4 to step S12, and sets the output value of the audio circuit 2 to the volume corresponding value L2 stored in the volume storage unit 8 (step S12). For this reason, the volume from the speaker 3 becomes a sufficient volume. Further, the channel received by the television circuit 1 is set to the channel of the operated key (step S13). Thereafter, the operation as the wake-up timer is stopped, and the state shifts to a normal reception state.

On the other hand, at time 2 when the volume is increased by the above-mentioned loop operation, the user who wakes up, for example,
It is assumed that the channel up key of the remote controller 7 is operated. In this case, the control unit 5 shifts the operation from step S4 to step S12, and sets the output value of the audio circuit 2 to the volume corresponding value L2 stored in the volume storage unit 8 (step S12). For this reason, the volume from the speaker 3 is slightly reduced. In addition, the channel received by the television circuit 1 is changed from the channel received so far to the next higher channel (step S13).
Thereafter, the operation as the wake-up timer is stopped, and the state shifts to a normal reception state.

On the other hand, when the user is away, no operation is input to the input means 13. Therefore, the audio circuit 2
Output value continues to increase. Then, when 10 seconds have elapsed after setting the output value of the audio circuit 2 to the upper limit L3 (time T3), the control unit 5 shifts the operation from step S6 to step S11. Then, step S11
In, the control unit 5 stops the operation of the power supply unit 4 and shifts to the standby mode.

The operation at the time of wake-up has been described above, and the operation at the time of the sleep timer will now be described.

Assume that the user operates a timer key (not shown) of the remote controller 7 in a state where the sound volume (a sound volume corresponding value) is set to the level L5 shown in FIG. 6 in order to fall asleep. When the timer key is operated, the control unit 5 starts measuring a period (predetermined period) determined by the operation of the timer key (step S21) (assuming the predetermined period is 30 minutes).

The control unit 5 that has started counting the predetermined period checks whether or not an operation has been input to the input means 13 (step S22). And when no operation is input,
It is checked whether 2/3 of the predetermined period has passed (step S23). That is, it is checked whether 20 minutes have elapsed since the start of the time measurement. If not, the operations of steps S22 and S23 are repeated.

When 20 minutes have elapsed, the control unit 5 further executes 1/30 of the predetermined period (1 minute).
Is checked (step S24). If not, the operation returns to the operation in step S22. Therefore, after the start of the timing, the operation of steps S22 to S24 is repeated in a period until 21 minutes elapse.

When 21 minutes have elapsed, the operation moves from step S24 to step S25, and the output value of the audio circuit 2 is reduced by one stage. Then, in the period until the next one minute elapses, step S
22 to S24 are repeated, and then the audio circuit 2
Is reduced by one stage. Therefore, the output value of the audio circuit 2 is the time T at which 21 minutes have elapsed since the start of the time measurement.
From 11, the power is reduced step by step at one minute intervals.

When the volume is reduced by the above-described loop operation, it is assumed that the user has operated the channel key of the remote controller 7 at time T12 because he could not sleep. In this case, the control unit 5 shifts the operation from step S22 to step S31, and returns the output value of the audio circuit 2 to the volume corresponding value L5 set by the user. For this reason, the volume from the speaker 3 becomes a sufficient volume. Further, the channel received by the television circuit 1 is set to the channel of the operated key (step S32). Then, after that, the operation shifts to step S21, and the timing of the predetermined period is restarted.

Thereafter, the same operation as described above is repeated. Therefore, when no operation is input to the input unit 13, when 21 minutes have elapsed from the time T12 (time T13), the volume reduction is started. And
At time T14 when 30 minutes have elapsed from time T12, the control unit 5 determines that the clocking of the predetermined period has ended, stops the operation of the power supply unit 4, and shifts to the standby mode (steps S26 and S27).

Hereinafter, a second embodiment will be described. Note that the second embodiment has a configuration in which only the control unit 5 of the first embodiment is changed, and only the operation at the time of a sleep timer is different from the first embodiment. Therefore, the second
The electrical configuration of this embodiment, when shown as a block diagram, is the same as the configuration shown in FIG. For this reason, only the portions different from the first embodiment will be described below.

In the present embodiment, when the control unit 5 is used as a timer, the control unit 5 is configured to continue measuring a predetermined period of time even when an operation is input to the input unit 13 during the time measurement period. When the output value of the audio circuit 2 has not been reduced to the predetermined value even when the clocking of the predetermined period has ended, the timing at which the operation mode is shifted to the standby mode is determined by the sound volume reduction means. Until it is reduced to a predetermined value.

FIG. 3 is a flowchart showing the main operation of the second embodiment when operating as a sleep timer.
FIG. 7 is an explanatory diagram showing a change in volume at the time of the sleep timer. The operation of the second embodiment will be described with reference to these drawings as necessary.

It is assumed that the user operates a timer key (not shown) of the remote controller 7 in a state where the volume (the volume corresponding value) is set to the level L5 shown in FIG. 7 in order to fall asleep (time T21). . When the timer key is operated, the control unit 5 starts measuring a period (predetermined period) determined by operating the timer key (step S4).
1) (It is assumed that the predetermined period is 30 minutes).

The control unit 5 which has started time counting for a predetermined period checks whether or not an operation has been input to the input means 13 (step S42). And when no operation is input,
It is checked whether 2/3 of the predetermined period has passed (step S43). That is, it is checked whether 20 minutes have elapsed since the start of the time measurement. If not, the operations of steps S42 and S43 are repeated.

When 20 minutes have elapsed, the control unit 5 further executes 1/30 of the predetermined period (1 minute).
Is checked (step S44). If not, the operation returns to the operation of step S42. Therefore, the operations of steps S42 to S44 are repeated during a period from the start of the timing to the lapse of 21 minutes.

When 21 minutes have elapsed, the operation moves from step S44 to step S45, and the output value of the audio circuit 2 is reduced by one stage. Then, in the period until the next one minute elapses, step S
42 to S44 are repeated, and then the audio circuit 2
Is reduced by one stage. Therefore, the output value of the audio circuit 2 is the time T at which 21 minutes have elapsed since the start of the time measurement.
From 22, the power is reduced one step at a time at one-minute intervals.

When the volume is reduced by the loop operation described above, it is assumed that the user has operated the channel key of the remote controller 7 at time T23 because he could not sleep. In this case, the control unit 5 shifts the operation from step S42 to step S51, and sets the output value of the audio circuit 2 to the volume L5 set by the user.
To return to. For this reason, the volume from the speaker 3 becomes a sufficient volume. Further, the channel received by the television circuit 1 is set to the channel of the operated key (step S52). Thereafter, the operation shifts to step S42. For this reason, the clocking of the predetermined period is continued.

After shifting to step S42, the operations of steps S42 to S44 are repeated until 1/30 of the time period (1 minute) elapses.
When one minute has elapsed, the output value of the audio circuit 2 is reduced by one stage (step S45). Then
After the determination operation in step S46, the process proceeds to step S42. Therefore, until the clocking of the predetermined period (30 minutes) is completed (until the period of 30 minutes elapses from time T21), the volume is reduced by one step every minute.

Then, at time T24 when 30 minutes have passed from time T21, the clocking of the predetermined period ends. For this reason, the control unit 5 shifts the operation from step S46 to step S47, and the output value of the audio circuit 2 is reduced to a predetermined value (volume reduced by 9 steps from the volume L5 set by the user). Check if it has gone down. In this case, since the output value has not dropped to the predetermined value, the operation shifts from step S47 to step S42. Therefore, even after the time T24, control is performed so that the sound volume is reduced step by step every minute.

Then, at time T25 when the output value is reduced to the predetermined value, the operation shifts from step S47 to step S48. For this reason, the control unit 5
The operation of the power supply unit 4 is stopped, and the mode shifts to the standby mode.

As described above, in the above embodiment, when an operation is input to the input means 13, the volume changes to the volume set by the user. Further, an operation corresponding to the input key is executed. Therefore, for example, when changing the channel, only the operation of the channel key or the channel up / down key is performed, so that both the return of the volume and the change of the channel are performed.
Usability is good.

In the above configuration, only when the key input to the input means 13 is a key related to the volume, the operation corresponding to the input key (step S13, step S13).
S32, S52) may not be executed. Then, in this configuration, in order to return to a volume that is easy to hear, even when a key related to the volume is operated, the restored volume is the same as the value set by the user. Therefore, usability is further improved.

When an operation is input to the input means 13, the operation corresponding to the input key (steps S13, S32, S52) may be omitted irrespective of the type of the input key. it can. In such a configuration, in order to return the reduced volume or the increased volume to the volume set by the user, an arbitrary key of the input means 13 is operated. That's all I need to do. Therefore, the input operation for restoring the volume is extremely easy.

Further, in the case of the volume reduction means, until a period of 2/3 (a period of any other ratio or any fixed period or the like can be used) between the timings elapses. , The sound volume is not reduced. For this reason, the same volume is continued for a while after the timer operation is started, so that the user can fall asleep while fully enjoying the broadcast.

Although the present invention is not limited to the above embodiment and has been described with reference to a case where the present invention is applied to a television, the present invention can be similarly applied to other electronic devices such as a radio and a tuner.

[0059]

As described above, the electronic device according to the present invention has a sound circuit whose output value can be controlled, a sound volume storage means for storing a sound volume corresponding value corresponding to a sound volume set by a user, At the set time, timer means for shifting the standby mode to the operation mode, input means for inputting an operation instruction, and when shifting from the standby mode to the operation mode, the output value of the audio circuit is gradually increased. The present invention is applied to an electronic device having a volume increasing means for increasing the volume, wherein the volume increasing means gradually increases the output value of the audio circuit, and when an operation is input to the input means, the output of the audio circuit is increased. The value is set to the sound volume corresponding value stored in the sound volume storage means. Therefore, when the volume increasing means gradually increases the output value of the audio circuit, when an operation is input to the input means, the volume immediately changes to a volume that is easy to hear, so that the volume is at a level that is difficult to hear. Also,
Immediately, the volume can be changed to a level that is easy to hear.

Further, even when the volume increasing means increases the output value of the audio circuit to a preset upper limit value, when no operation is input to the input means, the operation mode is set to the standby mode. Control means for shifting is provided. Therefore, when the situation where the volume increases to the upper limit value occurs because the user is absent, the standby mode is automatically set. When the user is absent, the mode can be automatically shifted to the standby mode.

Further, the electronic device according to the present invention is provided with an audio circuit capable of controlling an output value, volume storage means for storing a volume corresponding value corresponding to a volume set by a user, and an instruction to start timing. When the timer starts counting time for a predetermined period of time, and after the time measurement ends, the timer means shifts the operation mode to the standby mode, input means for inputting an operation instruction, and audio The present invention is applied to an electronic device including a sound volume reducing unit that gradually reduces an output value of a circuit, and the volume reducing unit is configured to gradually reduce an output value of an audio circuit when an operation is input to an input unit. In this method, the output value of the audio circuit is restored to the value corresponding to the sound volume stored in the sound volume storage means, and then gradually reduced. Therefore, only by inputting an operation to the input means, the volume is gradually reduced after returning to the easy-to-hearing volume set by the user. It is possible to eliminate the need for an input operation for reducing the number.

Further, when an operation is input to the input means while the timer is performing time counting, the timer means restarts the time counting for the predetermined period, and the volume reducing means includes the timer means. The output value of the audio circuit is gradually reduced in response to the restart of the time measurement. Therefore, the operation of the timer means and the operation of the volume reduction means are restarted only by inputting an operation to the input means, so that the timer operation can be easily restarted.

Further, the timer means may determine a timing for shifting the operation mode to the standby mode when the output value of the audio circuit has not decreased to the predetermined value even when the timing of the predetermined period has ended. , Until the sound reduction means reduces the output value of the sound circuit to a predetermined value. Therefore, even when the clocking period ends, the operation mode is continued when the volume is high, and the standby mode is set when the volume is low. For this reason, even when the input means is operated near the end of the time counting by the timer means, it is possible to shift to the standby mode when the volume is sufficiently reduced.
