Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and more particularly to an electronic device having a hold function for invalidating the operation of a predetermined operation member.

[0002]

2. Description of the Related Art Conventionally, there has been known an electronic device such as a portable recorder having a so-called hold function for disabling reception of an operation switch of a device main body in order to prevent an erroneous operation when carrying the device. I have.

However, in the case of an electronic device having such a hold function, if a predetermined operation is performed once the hold function is set, this operation is not accepted. The desired operation cannot be performed until after the operation of canceling is performed. Furthermore, if the user forgets or does not know that the hold function has been set, the desired operation cannot be performed, which is extremely inconvenient.

[0004] As a technique for solving such a problem,
Japanese Patent Application Laid-Open No. 5-266645 discloses an example in which when a predetermined operation is performed in a state where a hold function is set, a display indicating that the apparatus is in a hold state is displayed on a display unit of the main body of the device. According to this technique, it is possible to accurately notify the user that the hold function is working, but reception of a predetermined key operation is still invalidated.

On the other hand, in recent years, in information processing apparatuses having a clock function using a battery as a power source, many apparatuses designed to reset the clock function once when the battery is removed from the apparatus main body are known. In such an apparatus, since it is necessary to perform the time adjustment process again, a technique of automatically shifting to the time adjustment mode when a battery is loaded in consideration of user's convenience has been proposed.

[0006]

However, in an electronic device having the above-mentioned hold function and requiring time adjustment every time the battery is replaced, once the hold function is set, the user once operates the hold function. Only after the cancellation operation has been performed can the time be set. In this case, even if the display indicating the hold state is displayed, the user cannot adjust the time without releasing the hold function each time.

Originally, this time adjustment processing is performed at the time of battery replacement, and it can be said that it is not necessary to set the above-mentioned hold function to prevent careless operation. Therefore, the user has been inconvenienced even though it is not necessary to activate the hold function even for such processing.

The present invention has been made in view of such a problem, and an object of the present invention is to provide an electronic device that can accept an operation that does not require a hold function even in a hold state.

[0009]

According to a first aspect of the present invention, there is provided an electronic apparatus having a hold function for invalidating an operation of a predetermined operation member.
In the initial setting mode for performing the initial setting of the electronic device, the operation of the operation member related to the setting is enabled even when the hold function is operated.

[0010] In order to achieve the above object, a second aspect of the present invention is provided.
The electronic device having a clock function, a hold function for invalidating an operation of a predetermined operation member, and an operation member for setting the time of the clock function, wherein the time setting of the clock function is performed. In the clock setting mode in which is possible, the operation of the operation member is enabled even when the hold function is operating.

In order to achieve the above object, a third aspect of the present invention is provided.
The electronic device of the present invention is characterized in that, in the second electronic device, the watch setting mode is set immediately after reset.

Input to a power amplifier (AMP) 13 that drives a speaker. The audio signal amplified by the power amplifier 13 is converted into a sound and is emitted from a speaker 14 that emits the sound.

The system control section 6 is constituted by a microprocessor (CPU), serves as control means for controlling the operation of each section of the audio recording / reproducing apparatus, and performs initial settings of the audio recording / reproducing apparatus. In the initial setting mode, even when the hold function is operated, the function as a means for controlling the operation of the operation member related to the setting is made effective.

A recording medium 7 such as a flash memory card is connected to the system controller 6 via a memory card controller and the like. This flash memory card 7
Is a recording medium which is detachable from the audio recording and reproducing apparatus and has an audio data area and an index information area in which predetermined audio data and index information relating to the audio data are respectively recorded.

The flash memory card 7 is provided with a switch for setting the type of memory (whether or not it is a read-only card or the like) and a switch for setting whether or not to prevent writing. The state of these switches is detected by the system controller 6 via the memory card controller when the flash memory card is mounted on the audio recording / reproducing apparatus.

Further, an address control circuit (not shown) is connected to the system control unit 6, and the operation button group 1
In response to the operation of step 5, an appropriate address signal is given to the address control circuit, and in addition to the audio data supplied from the digital signal processing unit 5, the recording date and time, index information, etc. are stored in the flash memory based on a predetermined format. Data recorded on the card 7 or data recorded on the flash memory card 7 is read and supplied to the digital signal processing unit 5.

An LCD display 9 for displaying various information related to the audio recording / reproducing apparatus is connected to the system control section 6 via a drive circuit 8. The LCD display 9 displays information relating to various operation modes, time information, date information, the presence or absence of an audio file associated with the date, the number of files, and the like.

The system control unit 6 is supplied with power from a battery 10 serving as a power supply for the audio recording / reproducing apparatus.
Then, when the battery 10 is removed from the apparatus main body, the clock function is reset once. Then, when it is detected that the battery 10 is loaded at the time of battery replacement or the like, each unit is controlled so as to automatically shift to the clock adjustment mode. The details will be described later.

A hold switch (HOLD) 101 is connected to the system control unit 6. The hold switch 101 is a slide switch disposed on the outer surface of the audio recording / reproducing apparatus, and when set to an on state, in principle, accepts operation of other operation buttons described later, which is a so-called hold function. Is set. That is, the system control unit 6 sets the hold switch 1
After detecting the ON operation of 01, the switch operation of the operation button group 15 and the like is not accepted in principle until the switch is turned off. This can prevent erroneous operation when carrying.

Although the details will be described later, even when the hold switch 101 is set to the ON state, when the system control unit 6 is reset, for example, when replacing the battery, only the clock setting button 105 is accepted. I have.

As described above, the operation button group 15 is connected to the system control unit 6. The operation button group 1
5 is a record button (REC) 102 and a play button (PL)
AY) 103, stop button (STOP) 104, fast forward button (FF) 106, fast reverse button (REW) 10
7. It is composed of various operation buttons such as a clock setting button 105.

Of these operation buttons, the clock setting button 105 is a switch operated when setting the time. However, when the hold switch 101 is in an off state, it is also possible to operate the system even when the hold switch 101 is in an on state. Control unit 6
Immediately after is reset, for example, when replacing the battery, an operation can be accepted.

The fast-forward button 106 and the fast-reverse button 107 serve as switches for normal fast-forward and fast-reverse operations.
When 5 is turned on and the mode shifts to the clock setting mode, it functions as + SW and -SW for setting forward and backward times.

In addition, the system control unit 6 controls the operation of the memory card 7 in addition to the digital signal processing unit 5 according to the operation of each operation button of the operation button group 15. That is, when an audio signal is recorded by operating the record button, the audio data supplied from the digital signal processing unit 5 is supplied to the memory card 7 based on a predetermined format and recorded. Alternatively, when playing a predetermined sound by operating the play button, the system control unit 6 receives the data recorded in the flash memory card 7 and supplies it to the digital signal processing unit 5.

Next, the operation of the audio recording / reproducing apparatus according to the present embodiment will be described with reference to FIGS.

FIG. 2 is a flowchart showing main processing operations in the audio recording / reproducing apparatus of the present embodiment.

When power is supplied to the audio recording / reproducing apparatus, the system control unit 6 first performs predetermined initial settings as shown in FIG. 2 (step S1). Thereafter, the system control unit 6 determines whether or not the system control unit 6 has just been reset (step S2). For example, it is determined whether or not the battery 10 that supplies power to the system control unit 6 is a newly loaded battery. When it is determined that it is not immediately after resetting, for example, when the battery is not replaced, the key operation of the operation button group 15 and the like is received (step S3), and the state of the hold switch 101 is determined (step S4).

In step S3, when a key operation of the operation button group 15 or the like is received, the setting state of the hold switch 101 is checked in step S4. A process of invalidating the key operation of the button group 15 and the like is performed (step S5), and the process returns to step S3.

On the other hand, if it is immediately after the reset in step S2, the system control section 6 executes a subroutine "clock setting mode" described later before judging the state of the hold switch 101 thereafter (step S2).
A).

Thereafter, when the hold switch 101 is off in step S4, a key operation of the operation button group 15 or the like is accepted, and a predetermined process is performed. That is, a record button 102, a play button 103, a stop button 104, a fast forward button 106, a fast rewind button 10
7. On operation of the clock setting button 105 (step S6,
S8, S10, S12, S14), a predetermined subroutine "REC mode", "PLAY mode",
"FF mode", "REW mode", and "clock setting mode" are executed (steps S7, S9, S11, S1).
3, S15).

Here, among the predetermined subroutines,
The “REC mode” and the “clock setting mode” will be described.

FIG. 3 shows a subroutine "REC mode".
It is a flowchart showing a process. System control unit 6
When the record button 102 is turned on instead of the hold switch 101 being turned on, a normal recording process in this type of digital recorder is started (step S2).
1). When the recording process reaches the memory end, the process ends and returns to the main routine (step S2).
2) If the memory is still left, the operation of accepting the key operation of the operation button group 15 and the like is further monitored while continuing the recording process (step S23).

In this step S23, when a key operation of the operation button group 15 or the like is performed, the system controller 6
Confirms again the state of the hold switch 101 (step S24). When the hold switch 101 is set to the ON state, the operation button group 15
(Step S2)
5) Return to step S21 to continue the recording process.

If it is determined in step S24 that the hold switch 101 is in the off state, a process corresponding to the input key operation is performed. That is, when the key operated switch is the recording button 102 (step S
26) Then, a recording pause process (REC pause) is executed (step S27), and the process returns to the main routine.

On the other hand, when the switches operated by the keys are the reproduction button 103 and the stop button 104 (step S2).
8, step S30), execute the reproduction process and the stop process, respectively (step S29, step S31), and return to the main routine.

FIG. 4 shows a subroutine "clock setting mode".
It is a flowchart showing a process. System control unit 6
As described above, in step S2, the battery 1
At the time of reset, such as when 0 is exchanged, this timepiece setting mode is executed irrespective of the state of the hold switch 101 (see step S2A).

On the other hand, if the hold switch 101 is off, the clock setting mode is executed by operating the clock setting button 105 (see steps S14 and S15).

When the clock setting mode is executed, first, the system control section 6 causes the setting object (“hour”, “minute”, “second”) of the time display displayed on the LCD display 9 to blink. (Step S41). In the present embodiment, first, a portion corresponding to “hour” is blinked and displayed.

The system control unit 6 continues the blinking display and waits until a predetermined key operation is performed. If there is no key operation for three minutes or more, the system control unit 6 ends the clock setting mode (step S45). And return to the main routine.

If a key operation is detected during the standby period (step S43), this operation is performed by the clock setting button 1
05, fast forward button 106 or fast rewind button 107
(These switches are collectively referred to as a clock setting switch) (step S44).
If the switch is not a clock setting switch, the clock setting mode is terminated (step S45), and the process returns to the main routine.

In step S44, what was operated was the clock setting switch (clock setting button 105,
If it is either the fast forward button 106 or the fast reverse button 107), the next time the clock setting button 105 is turned on (step S46), the setting target is changed to the next target, for example, from "hour" to "minute". After the change (step S47), the process returns to step S41.

If the setting object is not changed in step S46, the setting object is incremented or decremented by operating the fast forward button 106 or the fast rewind button 107 (step S48, step S50) (step S49, step S51). ), And returns to step S41.

As described above, according to the audio recording / reproducing apparatus of the present embodiment, immediately after the system control unit 6 is reset, for example, when the battery 10 is replaced, the state of the hold switch 101 is determined. Instead, the clock setting mode can be automatically executed, so that the user can set the time without being bound by the state of the hold switch 101.

In the audio recording / reproducing apparatus of the present embodiment, the above-described time adjustment is described as an example of an operation that does not require the hold function. However, the present invention is not limited to this. It is possible to adapt the invention. In this case, the same effect as above can be obtained.

The sound recording / reproducing apparatus has been described as an example of the best embodiment of the present invention. However, the present invention is not limited to this, and the idea of the present invention is not limited to other "electronic devices having a hold function", especially portable electronic devices. For example, it goes without saying that the present invention can be applied to a portable telephone, a portable electronic terminal device, a portable computer device, an electronic timepiece, and the like.
