Abstract

PROBLEM TO BE SOLVED: To eliminate the user's confusion or misconception when there is operation of its unfeasible condition among plural kinds of operation that can be instructed at the time of operating an operator by setting such operation to be executed by a reproducing means irrespectively of any operation system and performing this execution. SOLUTION: When an operating key is operated, whether a 1st function is in its unoperatable state or not is judged by a control part, and if operatable, whether a 2nd function is in its unoperatable state or not is judged. If both functions are operatable, an operation system of the operating key is judged. Processing is performed to execute operation of the 1st function when the 1st function is judged and operation of the 2nd function when the 2nd function is judged. When the 1st function is judged to be the unoperatable state at the outset, processing for executing the operation of the 2nd function is performed. When the unoperatable state of the 1st function is judged first, and then the 2nd function is also judged to be the unoperatable state, processing for executing the operation of the 1st function is performed irrespective of an operation system of an operating key.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reproducing, for example, audio and video.

[0002]

2. Description of the Related Art CDs (compact disks), MDs (mini disks), DATs (digital audio tapes),
Various recording media such as music / video such as DVD (digital video disc / digital versatile disc) have been developed. The playback operation of the playback device for these media is performed in response to various key operations provided as an operation unit.

[0003] By the way, downsizing and cost reduction of the device,
For various purposes such as improvement of operability, a certain operation key is often used also as a key for executing a plurality of types of operations of the device. For example, in a device such as a CD player, a play key and a pause key are also used, and an AMS access key for AMS track access (start of music) is also used as a variable speed play (cue / review) key. There is. In some cases, the up / down key is also used for volume operation and tone adjustment operation.

As described above, when one operation key is used for a plurality of operation instructions, it is necessary to distinguish which operation is desired by the user. One operation key that can be used for multiple operations that cannot overlap at a certain time, one that distinguishes operation contents according to the mode at the time of operation, and one that distinguishes operation contents by the operation method at the time of operation There are things to do. When the playback operation and the pause operation are combined, the operation can be distinguished from the pause operation if the playback is being performed, and from the playback operation if the playback is not being performed. That is, this is an example in which operations do not overlap at a certain point in time. An example in which the up / down key is also used for volume operation and tone adjustment operation is an example in which the function of the key is changed according to the mode.

[0005] However, there is an example of an AMS operation and a variable speed reproduction operation that may be performed at a certain point in time and are not appropriate to be distinguished depending on the mode. Therefore, when it is desired to use the AMS operation and the variable speed reproduction operation with one operation key, the operation contents are distinguished by, for example, the operation method of the user. As a specific example, an AMS operation is performed when the operation key is momentarily pressed, and a cue / review operation is performed when the operation key is continuously pressed.

In some cases, a continuous AMS operation may be used in addition to the AMS operation and the cue / review operation. For example, by pressing the operation key momentarily and then immediately pressing it continuously, while the continuous pressing is being executed,
This is an operation for continuously executing cueing access. CD
In the case of a player or the like, when the track of the first track is being played, the head of the second track, the head of the third track, the head of the fourth track,...
························································································

[0007]

However, this AMS
In an example where the operation is used in combination with the cue / review operation, there is usually a possibility of either operation. Therefore, a control unit such as a CD player determines the operation content according to the user's operation method and determines the specified operation. Although it is executed, a part of a plurality of types of operation contents which are also used as keys may be inoperable. For example, when the tenth track, which is the last track of a CD containing ten songs, is reproduced, the next song does not exist in the first place, and therefore, it is impossible to access the beginning of the next song. Therefore, for example, when the user performs an instantaneous nest operation on the AMS and the cue / review key during playback of the last track (that is, when a cueing access operation is performed), such an operation is not possible. Does not execute the operation according to the operation. That is, the operation is invalidated and ignored.

[0008] However, for the user, the fact that the operation corresponding to the operation is not performed may be misunderstood as an abnormal operation or a failure. It is also conceivable that the user notices that it is the last track immediately after the momentary push, and performs a continuous push in a hurry, but this user operation corresponds to the operation method of the continuous AMS operation described above. Become. During the reproduction of the last track, it is of course impossible to make continuous head-to-head access in the direction of the next song, so that the operation is invalidated and ignored.

[0009] As in this example, in particular, when the operation content is distinguished by the operation method, and when an operation corresponding to a certain operation content is inoperable, disabling the operation can cause a failure or the like to the user. There is a problem of giving a misunderstanding and confusion of the operation.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has a structure in which an operation element capable of instructing a plurality of kinds of operations of a reproducing unit is provided according to an operation method. An object of the present invention is to prevent a user's misunderstanding and confusion of an operation without ignoring the operation even in a situation where an operation instructed by the operation method is impossible.

For this purpose, the control means, when the operation element is operated, determines whether or not there is an operation in a state where the operation cannot be executed among a plurality of kinds of operations which can be instructed by the operation element in the reproduction means. If there is, the control of the operation to be executed by the reproducing means is performed regardless of the operation method of the operation element. In other words, even when a part of a plurality of operations that are instructed by the operation method of the operation device is inoperable and the user operates the operation device in an operation method corresponding to the operation that cannot be performed, Take some other appropriate action without ignoring the operation. The appropriate operation is an operation instructed by another operation method of the operator.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of a disc player will be described as an embodiment of a reproducing apparatus according to the present invention. Before describing the example of the disc player, the reproducing apparatus according to the embodiment will be characterized. An image of the operation corresponding process will be described with reference to FIG.

FIG. 1 shows a processing method when an operation key capable of instructing a plurality of types of operations is operated according to the operation method. For some operation keys,
For example, depending on the operation method such as momentary push and continuous push,
It is assumed that the setting is such that the operation as the first function and the operation as the second function can be instructed.

When the operation key is operated in step F100, the control unit (such as a microcomputer as a controller) of the reproducing apparatus executes step F101.
Then, it is determined whether the first function is currently inoperable. If the first function is operable, step F10
At 2, it is determined whether the second function is inoperable.

If both the first function and the second function are operable, the process proceeds to step F103, where the operation method of the operation key is determined for the first time. For example, it is determined whether the operation key is pressed for a moment or is continuously pressed.
This determination is made by a method such as whether the time during which the operation key is pressed is less than a predetermined threshold value, or whether the operation is still continued during the time exceeding the threshold value.

When it is determined that the operation of the first function is determined by the determination of the operation method, the process proceeds from step F104 to F105, and processing for executing the operation of the first function is performed. On the other hand, if it is determined that the operation of the second function is not the operation of the first function based on the determination of the operation method, the process proceeds from step F104 to F106 to perform processing for executing the operation of the second function.

However, at the stage of step F101, the first
If it is determined that the function is inoperable, the process proceeds to step F106, regardless of the operation method of the operation key, to perform processing for executing the operation of the second function. If it is determined in step F102 that the second function is inoperable, the process proceeds to step F105, regardless of the operation method of the operation key, to execute a process for executing the operation of the first function. Do.

That is, when one of the functions is inoperable, regardless of the operation method of the operation keys, the operation control of the executable one is executed so that the operation is not invalidated.

A disk player as an embodiment configured based on such a processing image will be described with reference to FIGS. FIG. 2 shows a front panel of the disc player of the present embodiment. This disc player is a car-mounted disc player (CD player). A display unit 3 such as a liquid crystal display device is formed on a front panel of the disc player. The display unit 3 shows the operation state of the disc being reproduced, the track number, the recording time / reproduction time, the editing operation state, the reproduction mode, and the like. The front panel is provided with a disc insertion portion 21 into which a disc is inserted into a disc player and the disc is detached in response to an operation of an eject key 22.

The front panel is provided with various operation keys for operations relating to disc reproduction. That is, the play / pause key 23, the stop key 24, the head access and the cue / review operation shared AM
An S-key 25, an AMS + key 26, an up / down key 27, and the like. In addition, an operation key for switching a display mode, an operation key for setting a reproduction mode, an operation key for switching an operation mode, and the like are also provided.

The AMS-key 25 is a dual-purpose operation key for accessing to the beginning of the current reproduction position from the current reproduction position and for reproduction reproduction (reverse reproduction).
The momentary pressing operation is a cueing access operation in the return direction. For example, during playback of a track, the AMS-key 25
When a momentary push operation is performed, it is an operation for cueing access to the head position of the track, and when a similar momentary push operation is continuously performed, the track number is sequentially reduced in the younger direction. It is assumed that the search access access instruction has been given. The operation of continuously pressing the AMS-key 25 is a review reproduction operation. Further, when the continuous pressing is performed immediately after the momentary pressing operation, the operation is an instruction for a continuous access operation in the direction of the track number sequentially smaller.

The AMS + key 26 is a dual-purpose operation key for performing cueing access and cue reproduction (fast-forward reproduction) in the forward direction from the position currently being reproduced. Out access operation. For example, when the AMS + key 26 is momentarily pressed during the reproduction of a certain track, it is regarded as an operation for cueing access to the head position of the next track of the track. Is performed, it is determined that an instruction for a cueing access in a direction of sequentially increasing track numbers has been performed. The operation of continuously pressing the AMS + key 26 is a cue reproduction operation.
Further, when the continuous pressing is performed immediately after the momentary pressing operation, the operation is an instruction for a continuous access operation in the direction of sequentially increasing the track number.

The up / down key 27 is used for various increment / decrement operations such as a volume adjustment operation and an equalizing adjustment operation in accordance with an operation mode switched by the user.

In this embodiment, these operating means are arranged on the front panel of the recording / reproducing apparatus for the sake of explanation. For example, the recording / reproducing apparatus can be operated by a remote commander using infrared rays or the like. May be provided. In the case of this example, as described later, the processing related to the operation of the AMS- key 25 and the AMS + key 26 has a feature.
Even when the remote commander is provided with an AMS- key and an AMS + key for performing the same dual-purpose operation, the corresponding processing of the operation is performed by the AMS- key 25 and the AMS + key on the front panel.
What is necessary is just to perform the same processing as the corresponding processing for the operation of the key 26.

FIG. 3 shows a block diagram of the disc player. The disc inserted into the disc player from the disc insertion section 21 of FIG. 2 is loaded into the player section 6 and driven for reproduction.

As the player section 6, a disc is loaded,
A loading mechanism for discharging, a disk rotation driving mechanism, an optical pickup mechanism, an RF matrix amplifier, and the like are provided. Then, laser light is emitted from the optical pickup mechanism in a state where the disk is rotated by the CAV or CLV method by the disk rotation drive mechanism, and a current corresponding to the reflected light is obtained to read information from the disk. The current signal, which is the detection information of the reflected light, is subjected to current-voltage conversion, amplification, arithmetic processing, and the like in an RF matrix amplifier, and various signals are generated.

The RF matrix amplifier in the player section 6 generates a reproduction RF signal, a focus error signal, a tracking error signal, and the like. The outputs of these RF matrix amplifiers are supplied to the decoder section 7 and the servo section 10. .

The servo section 10 generates various focus, tracking, thread, and spindle servo drive signals from a focus error signal and a tracking error signal supplied from the RF matrix amplifier, a spindle error signal from the decoder section 7, and the like. Then, the servo operation relating to the disk reproducing operation of the player section 6 is executed.

The reproduced RF signal output from the player section 6 (RF matrix amplifier) is supplied to the decoder section 7. The decoder unit 7 performs binarization, EFM demodulation, CIRC error correction processing, and the like, and decodes information read from the disc into audio data. Further, the decoder unit 7 performs extraction of subcode and address data, extraction of rotation speed information, and the like.
And also decodes the character information recorded in a predetermined area (TOC, etc.) of the disk and the character information recorded as subcode data, and sends these character information to the controller 1. Supply.

The digital audio data output from the decoder 5 is subjected to audio processing such as equalizing, reverb and volume control in an audio processing section, and then converted into an analog audio signal in a D / A converter 9. It is supplied to a predetermined audio output part. For example, the audio signal is supplied to a speaker or a headphone output terminal via a volume control circuit and an amplifier circuit, and is output as sound.

Various operations during reproduction are controlled by a controller 1 formed by a microcomputer.
For example, the controller 1 controls the servo unit 1 for operations such as reproduction start and end, track access (starting access), fast forward reproduction (queue reproduction), and fast reverse reproduction (review reproduction).
0 and the operation of the player unit 6 are controlled.

The operation unit 5 is provided with operation keys for the user to perform various operations. That is, this operation unit 5
Correspond to the various operation keys (22 to 27, etc.) shown in FIG. The controller 1 operates information from the operation unit 5 and
Each unit is controlled according to the control program stored in the internal ROM.

The display section 3 provided on the front panel as shown in FIG. 2 shows a track number during reproduction, a reproduction progress time,
The display such as the operation state is executed based on the control of the controller 1. The controller 1 supplies data contents (character strings and the like) to be displayed to the display driver 2. Display driver 2
Denotes a controller 1 for a display operation on the display unit 3.
A display drive signal is generated based on the display data supplied from, and supplied to the display unit 3 to execute display. The management information memory 4 stores management information read from the TOC and other disks. The controller 1 controls the reproduction operation of the disk using the management information stored in the management information memory 4.

In such a disc player, A
FIGS. 4 to 6 show the processing of the controller 1 when the MS-key 25 or the AMS + key 26 is operated. The AMS key-on in step F200 in FIG.
This shows a state where the key 25 or the AMS + key 26 is operated.

When the AMS key is turned on, the controller 1 first checks in step F201 whether or not the operation is an operation of the AMS + key 26. AMS-key 25
If the operation is the operation of the AMS + key 26, the process proceeds to step F203. If the operation is the operation of the AMS + key 26, it is determined in step F201 whether or not the last track of the disc is currently being reproduced. If not, the process proceeds to step F203.

From step F203 onward, the AMS-key 25 or AM, which is also used as a shared operation key as described above,
This is a process of determining the operation method of the S + key 26. First, the internal timer t0 is reset to 0, and then in step F204
Step F20 while incrementing the timer t0 with
It is monitored in step 6 that the operation key is depressed (hereinafter referred to as key-off). The processing of the timer increment and the key-off monitoring in steps F204 and F206 is as follows.
It continues until it reaches sec. Therefore, step F2
06 indicates that the key-off is detected,
Pressing the S-key 25 or AMS + key 26 requires 2
This is the case where the operation is completed within 00 msec, and this is determined to be a momentary pressing operation. That is, in this example, 200 mse
With c as a threshold value, it is determined whether the button is pressed for a moment or continuously.

If it is determined that the button is momentarily pressed, the controller 1 advances the process to step F207 to execute the AMS mode process. That is, if the operation is the operation of the AMS-key 25, the servo unit 10 is instructed to access the head of the optical head in the player unit 6 in the return direction. If it is determined that the operation of the AMS-key 25 is momentarily pressed, the process proceeds to step F207, and if the AMS-key 25 is continuously operated again within a predetermined time, the continuous heading access in the return direction of the optical head is performed. The control is performed so as to perform the control. Operation of step F200 is AM
If the operation is the operation of the S + key 26 and the process proceeds to step F207, the servo unit 10 is instructed to cause the optical head in the player unit 6 to search for the head in the advancing direction and access. A
If it is determined that the operation of the MS + key 26 is momentarily pressed, the process proceeds to step F207, and if the AMS + key 26 is continuously operated again within a predetermined time, a continuous cueing access is performed in the advance direction of the optical head. Will be controlled.

When these operation controls have been completed, the process proceeds to the process of FIG. 6 as indicated by step F208.

On the other hand, if the count value of the timer t0 becomes 200 msec or more in step F205 without detecting the key-off in step F206, step F200
It is determined that the operation started by is pressed continuously. Then, the process proceeds to step F209 to execute the queue / review mode process. That is, if the operation is the continuous pressing of the AMS-key 25, the servo unit 10 is controlled so that the review reproduction is executed, and if the operation is the continuous pressing of the AMS + key 26, the cue reproduction is executed. To control the servo unit 10.

The process of steps F204 → F205 → F209 is continued until a key-off is detected in step F210 while instructing a cue or review reproduction operation. Playback or review playback will be continued. If key-off is detected in step F210,
The process proceeds to step F211 to end cue reproduction or review reproduction, and then proceeds to the process of FIG.

The process of FIG. 6 which proceeds from step F208 or F211 is a key-off effective standby process. In other words, when the key pressing force of the user is momentarily weakened and the key is turned off without being conscious, this is a standby process for not actually performing the key-off process.

For this purpose, in step F218, the controller 1 resets the internal timer t1 to zero. Subsequently, in step F219, while the timer t1 is incremented, the pressing of the operation key determined to be key-off in step F221 is turned on again. (Hereinafter referred to as key-on). The processing of timer increment and key-on monitoring in steps F219 and F221 is continued until the count time as the timer t1 reaches a certain standby time tx in step F220. The waiting time tx is, for example, 100 to
It is a short time of about 200 msec.

The case where the key-on is detected in step F221 means that the user's AMS-key 25 or AMS
The pressing operation force of the + key 26 is momentarily weakened, and step F2
In step F2, it is determined that the continuous pressing operation has been completed at 10 and the user immediately reapplies the pressing operation force immediately after that, or in order to continuously perform the cueing access operation.
After the time point at which it is determined that the key is turned off in step 06, (step F
The pressing operation is performed again (at a time interval that is not determined to be a continuous access operation at 207).

In these cases, since the user is in a state where the same operation is desired to be continued, the process proceeds to step F201 and subsequent steps in FIG. Then, in this case, since the user performs the same momentary push or the continuous push as in the immediately preceding operation, the process proceeds to the cueing access / cue / review playback as in the immediately preceding operation.

On the other hand, if it is determined in step F220 that the timer t1 has exceeded the time tx, it is determined that the user has finished the operation in the immediately preceding step F206 or F210, and the processing related to the AMS key-on is terminated. Return to the state before the operation. In other words, during cueing access or cue / review playback, playback returns to the playback state. During cueing, cueing access or cue / review playback pauses when cue / review playback is performed. Return to.

The above processing is performed when the operation is performed in accordance with the operation method (short press or continuous press) according to the original setting of the AMS- key 25 or the AMS + key 26. In the following steps F201 and F202, when it is determined that the operation of the AMS + key 26 has been performed during the reproduction (or during the pause) of the last track, the processing proceeds to the processing of FIG. Become.

In this case, there is no track after the last track, so that it is impossible to access the beginning in the forward direction. Therefore, step F20
From 3, the operation method determination processing as in F <b> 205 is not performed, and the process proceeds to step F <b> 212 in FIG. 5 to immediately perform the cue operation processing. That is, since the operation is the AMS + key 26, the servo unit 10 is controlled so that cue reproduction is executed.

Then, the key-off is monitored in step F213 while the servo unit 10 and the player unit 6 execute the cue reproduction operation, and it is monitored in step F214 whether the end of the last track (for example, the end of the music) has been reached. . When the user ends the operation by pressing the button for a moment, the process proceeds from step F213 to F215, and the cue reproduction process ends. Even if the user presses the key continuously for the purpose of cue reproduction, if the key is turned off before reaching the track end, the process proceeds from step F213 to F215, and the cue reproduction process is terminated. Then, the process proceeds to the key-off standby process of FIG. 6, and the above-described key-off standby and the operation after the standby time are completed. Of course, if the AMS + key is operated during the standby time, the process returns to step F201, so the process again proceeds to step F212 in FIG. 5 to execute cue reproduction control.

If it is detected in step F214 that cue reproduction has reached the end position of the last track without detecting key-off in step F213, cue reproduction cannot be performed any further.
In step F217, a pause message is displayed on the display unit 3 such as "END" to inform the user that no further cue reproduction is possible.

As described above, in this example, the AMS + key 26
If the AMS + key 26 is momentarily pressed to perform a cueing access operation, the operation is invalidated if the cueing access in the advancing direction is not possible. An operable cue reproduction is performed without performing an operation. Therefore, there is no situation in which the operation is unresponsive to the operation, and the user is not misunderstood as a failure or the like. Also, if the user understands that the current position is the last track, in that situation, there is no need to request a cueing access in the forward direction, and the operation of the AMS + key 26 requires a cue reproduction. Therefore, by immediately performing cue reproduction without detecting the operation method or the like, the operation response is improved, and comfortable operability can be provided to the user.

Although the present embodiment has been described with reference to the example of the AMS + key 26, the present invention is not limited to this. The present invention can be applied to a case where a state in which the operation cannot be performed is considered. Although the disk player has been described as an embodiment, the reproducing apparatus of the present invention can be applied as a reproducing apparatus corresponding to various media such as CD, MD, DAT, and DVD.

[0052]

As described above, according to the present invention, when an operator capable of instructing a plurality of types of operations of the reproducing means is operated according to the operation method, a plurality of operators which can be instructed by the operator are operated. When there is an operation that cannot be executed among the types of operations, the operation to be executed by the reproducing unit is set and executed regardless of the operation method.
This has the effect of invalidating the operation and preventing the user from erroneously recognizing or confusing the operation in response to the operation, and providing comfortable operability by setting the operation to be performed at that time. Can be provided. Especially in the case of an operator that can instruct access operation and variable speed playback operation,
By controlling the execution of the variable-speed reproduction operation regardless of the operation method when the access operation is disabled, the effect of comfortable operability and elimination of confusion and erroneous recognition of the user becomes useful.
