Description

[0001]
[Industrial application fields]
The present invention relates to an electronic device capable of performing hold setting for invalidating a predetermined key operation, and is particularly suitable as a device such as a portable tape player or a disc player.
[0002]
[Prior art]
In particular, in a device such as a portable tape player or disc player, hold setting is performed so that an operation key is not accidentally pressed when being carried and an operation not desired by the user is performed. What can be known.
For example, if the hold setting is performed during the reproduction operation, even if the stop key or the fast-forward key is pressed during that time, these are invalidated, and the reproduction operation is continued, that is, no malfunction occurs. If hold is set when the power is turned off, the power will not be turned on even if an operation to turn on the power by mistake is performed, thereby avoiding unnecessary power consumption.
[0003]
By the way, in an electronic device, an operation key for turning on / off an operation power supply is usually provided. However, in a portable electronic device, it is desired to reduce the number of operation keys to promote downsizing and cost reduction. Also, for example, in order to avoid the need for a double operation of performing a playback operation after turning on the power when performing a playback operation, for example, a playback key is also used as a power key, and a dedicated power key is used. It is also conceivable not to set up.
That is, if a playback key is pressed when the power is turned off in a tape player or the like, the power is turned on and a playback operation is executed. Therefore, the user can listen to the playback sound by a one-touch operation.
[0004]
[Problems to be solved by the invention]
However, if the dedicated power key is not provided, there is a problem that an operation for turning off the power is inconvenient. That is, when the power key is not provided, the user cannot turn off the power. For this reason, in order to turn off the power, for example, the operation stop time is measured and the operation is not performed for a predetermined time or more. A method called auto power off that automatically turns off the power can be considered, but in order to respond to intermittent operation by the user, the operation stop period until auto power off is executed is set to a short time. That is not appropriate. For this reason, for example, about 2 minutes or 3 minutes to 10 minutes is set as the count period until the auto power off is executed.
The count period until the auto power off is performed while the power is on means that wasteful power consumption occurs, and particularly in battery-powered devices, the battery life is greatly affected.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of such problems, and it is an object of the present invention to make it possible to turn off the power by a user operation even when a dedicated power operation means is not provided, and to eliminate wasteful power consumption.
[0006]
As Therefore electronic devices, a plurality of operating means for instructing execution of a predetermined operation, with the whole of the operating means, and a hold operation means can perform the hold setting operation for invalidating the operation, the hold operation means When the hold setting by the hold operation means is performed in the operation stop state based on the operation means , the predetermined operation control is performed based on the operation of the operation means when the hold setting by the operation means is not performed. And a control means for performing control to turn off.
[0007]
Further, when the power is off and the hold setting is not made, the control means turns on the power when all or a part of the operation means is operated, and determines a predetermined value according to the operation means. The operation control is performed.
The electronic device further includes a power source unit including a dry battery or a rechargeable battery, and a switch. When the hold setting operation is performed by the hold operation unit in the operation stop state based on the operation unit, the power control from the control unit is performed. The signal opens the switch so that the power is turned off.
[0008]
[Action]
It is meaningless to set the hold while the operation is stopped. In other words, holding it when the power is on and in the stop state does not lead to power saving, but there is no advantage (to save power, the power is off so that the power is not turned on by incorrect power operation. Hold must be set, and in order to prevent erroneous operation so that no operation is performed, it is only necessary to hold in the power-off state, so there is almost no advantage of preventing erroneous operation in the stopped state. ). For this reason, there is no problem even if the hold operation functions as a power-off operation while the operation is stopped.
[0009]
If a device that provides a power-on operation function to a predetermined operation key without providing a dedicated power operation means, the device can be reduced in size and reduced if the power can be turned off by a hold operation while stopped. It is possible to realize cost reduction and one-touch operation until operation execution, and eliminate unnecessary power consumption.
[0010]
【Example】
Examples of the electronic apparatus according to the present invention will be described below with reference to FIGS. The electronic apparatus of this embodiment will be described as a portable cassette tape player.
FIG. 1 is a block diagram showing a main part of the embodiment, in which 1 is a power source unit using a dry battery or a rechargeable battery, and 2 is a DC-DC converter. The power supply as a device is turned on and off by opening and closing the switch 2a in the DC-DC converter 2. When the switch 2a is closed and the power is on, the DC voltage from the power supply unit 1 is supplied to the converter block 2b, and for example, E, + E ₁ , -E ₁ , + E as the power supply voltages necessary for each circuit unit. A power supply voltage such as ₂ is generated and output.
When only one system is required as the operating power supply in all circuit units (for example, only the output voltage E of the power supply unit 1 is sufficient), only the switch 2a for turning on / off the power supply voltage output of the power supply unit 1 is provided. Good. For example, an analog switch may be provided.
[0011]
Reference numeral 3 denotes a circuit block, and 4 denotes a mechanical deck unit which operates by power supply from the DC-DC converter 2. That is, the mechanical deck unit 4 performs the magnetic tape running operation, and the circuit block 3 performs the equalizing and amplification of the audio signal from the magnetic head to output the audio signal, and the input audio signal is output from the magnetic head to the magnetic tape. To record. Reference numeral 4a denotes a motor in the mechanical deck unit 4, which corresponds to a motor for driving a capstan or a reel.
[0012]
Reference numeral 5 denotes a controller formed by a microcomputer or the like, which controls the operation of the circuit block 3 and the mechanical deck unit 4 in accordance with user operations and processing programs. Further, with respect to the switch 2a is powered control signal S _P output from the controller 5, the switch 2a of the ON / OFF, that is, power on / off control is performed. Reference numeral 5a denotes a clock oscillator.
[0013]
Reference numeral 6 denotes a reproduction key, 7 denotes an FF (fast forward) key, 8 denotes a REW (fast reverse) key, and 9 denotes a stop key, which are keys for the user to operate the loaded cassette tape. That is, when the reproduction key 6 is pressed, the controller 5 performs tape reproduction traveling control on the mechanical deck unit 4 and causes the circuit block 3 to execute reproduction signal processing. The reproduction key 6 also serves as a pause key. If the reproduction key 6 is pressed during reproduction, the controller 5 executes a pause operation.
When the FF key 7 is pressed, a fast forward operation is executed, and when the REW key 8 is pressed, a fast reverse operation is executed. Further, if the stop key 9 is pressed during the reproduction / fast forward / rewind operation, these operations are stopped.
[0014]
The play key 6, the FF key 7, and the REW key 8 also have a function as a power-on key. When these keys are pressed in the power-off state, the controller 5 turns on the switch 2a to turn on the power. Depending on the operated key, playback, fast forward or fast reverse operation is executed.
Although not shown, the controller 5 is supplied with a small amount of power as a standby power supply even when the power is turned off, so that key operation detection and power-on control can be executed even when the power is turned off. ing.
[0015]
Reference numeral 10 denotes a hold key by a slide switch, for example, where the solid line is the hold-on operation position and the broken line is the hold-off operation position.
When hold-on, that is, hold setting is made, the controller 5 invalidates the operation of the operation keys 6 to 9 from that time, and therefore, while the hold setting is being performed, regardless of the operation of the operation keys 6 to 9 The operating state is continued. For example, if the user makes a hold setting during playback, the controller 5 does not perform stop control even if the stop key 9 is pressed, and the playback operation is continued. This allows music to be stopped or suddenly fast-forwarded even if the operation key is pressed due to inadvertently touching an operation key or hitting an operation key when listening to music while carrying it. It is possible to prevent the user from performing an undesired operation.
[0016]
When an operation such as a stop is performed during reproduction in such a hold state, the operation keys 6 to 9 are operated after the hold key 10 is once operated to cancel the hold setting.
[0017]
If the hold setting is made when the power is turned off, even if the operation keys 6 to 8 are pressed carelessly, this is invalidated and the power is not turned on. This prevents the power from being turned on without the user's knowledge and wasteful power consumption.
[0018]
In the present embodiment, as described above, the operation keys 6 to 8 are also used as the power-on key, and the hold key 10 is also used as the power-off key, so that the user can arbitrarily turn on / off the power without providing a dedicated power key. Is.
For this purpose, the processing of the controller 5 based on the operation of the operation keys 6 to 9 and the hold key 10 is as shown in FIG.
[0019]
The controller 5 always monitors the operation of the hold key 10, the reproduction key 6, the FF key 7, the REW key 8, and the stop key 9 regardless of power on / off (F102, F103, F104, F105, F106).
When the playback key 6 is pressed (F 103) it is, if it at that time in the power-off state, first closes the switch 2a is powered on by the power control signal S _P (F107, F108). Of course, this processing is not necessary when the power is on.
Then, it is determined whether or not the operation of the reproduction key 6 is performed during reproduction (F109). If the reproduction key 6 is not being reproduced, reproduction operation control is performed (F110). If playback is in progress, pause control is performed (F111).
[0020]
If FF key 7 is pressed (F 104) it is, if it at that time in the power-off state, first closes the switch 2a is powered on by the power control signal S _P (F112, F113). This process is not necessary when the power is on.
In step F114, fast-forward operation control is performed.
[0021]
Also if the REW key 8 is pressed (F105) Similarly, if if the time in the power-off state, the first power control signal S _P closes the switch 2a is powered on (F 115, F 116), in step F117 The fast reverse operation control is performed.
[0022]
When the stop key 9 is pressed (F106), first, it is determined whether or not a reproduction / fast forward / fast reverse operation is being performed (F118), and if these operations are being performed, a control for stopping the operation is performed. (F119).
[0023]
Further, when the hold key 10 is operated to the ON position and is set to hold, the processing does not proceed to steps F102, F103, F104, F105, and F106. Therefore, the reproduction key 6, FF key 7,. All operations of the REW key 8 and the stop key 9 are invalidated.
[0024]
If the hold key 10 is on, the process proceeds from step F102 to F120, and it is determined whether or not it is stopped. If it is not stopped, the process returns. In other words, the operation is held when the hold key 10 is turned on during an operation other than the stop or when the power is turned off, thereby eliminating malfunctions and wasteful power consumption.
[0025]
An affirmative result is obtained in step F120 when the user operates the hold key 10 to turn on when the operation is stopped.
In this case, the controller 5 will be powered off by opening the switch 2a by the power control signal S _P (F121).
That is, the hold key 10 functions as a power-off key when in a stopped state.
[0026]
Since the hold key 10 functions as a power-off key in this way, the user can perform a power-off operation after finishing the operation such as reproduction without providing a dedicated power-operation key, and therefore wasteful power consumption. Can be avoided.
[0027]
Note that when the vehicle is in the stop state, the time is measured by a timer, and the timer measurement time is compared with a predetermined time (for example, 5 minutes) in step F101. Then, when a predetermined time elapses in the stopped state, the process proceeds to step F122, and the controller 5 controls the switch 2a to turn off the power. That is, an auto power off operation is performed.
By performing such auto power-off control in this embodiment, even if the user forgets to turn off the power, the power is turned off after a predetermined time, and wasteful power consumption can be minimized. become.
[0028]
As described above, in the present embodiment , when the hold key is off, it is possible to reduce the size and cost of the device by not providing a dedicated power operation key , and also to use the playback key 6 and the like as the power on key. For example, when the power-on and the reproduction operation are executed by operating the reproduction key 6 once, the one-touch operation from the power-off state to the reproduction execution can be performed.
[0029]
Further, when the stop key is turned on, the power can be turned off by turning on the hold key 10, that is, the power can be turned off without waiting for the count period until the execution of the auto power off operation. This leads to savings, and in particular, a portable device that uses a rechargeable battery or a dry battery as a power source can substantially extend the battery life.
[0030]
The electronic apparatus of the present invention is a tape player as in the embodiment, a reproducing apparatus such as a CD player or a mini disk player, a recorder apparatus, a video reproducing apparatus, a video recording apparatus, etc. corresponding to a tape or a disk. Applicable.
Further, it goes without saying that various setting methods other than the above-described embodiment are conceivable for setting an operation key also used as a power-on key and a processing method corresponding to the operation.
[0031]
【The invention's effect】
As described above, the electronic apparatus of the present invention can perform power-off operation by operating the hold operation means at the time of stop without providing a dedicated power operation key, and therefore can prevent wasteful power consumption. In particular, when a rechargeable battery or a dry battery is used as a power source, the battery life can be extended.
When the hold key is off , the device can be reduced in size and cost by not providing a dedicated power operation key, and the power is turned on and the operation is performed by a single operation of a predetermined operation means. By doing so, it is possible to perform a one-touch operation from the power-off state to the operation execution, and it is possible to improve operability.
