Abstract

PROBLEM TO BE SOLVED: To obtain superior operability, in which transition to a fast forward reproducing mode is quickly accomplished, by setting the fast forward reproducing mode from the condition, in which a reproducing mode is set, by the operation of a reproducing mode setting means in a control means. SOLUTION: When a reproducing button PLAY is operated in a reproducing processing condition, a system control section 6 changes the condition to a fast forward reproducing which conducts the reproducing at a 1.5 times faster rate than the normal reproducing rate. If the continuous operation of the button PLAY exceeds a setting time and the continuous operation of the button PLAY is completed before a prescribed time, the fast forward reproducing is released and it is transitioned to a normal reproducing process. If the continuous operation of the button PLAY exceeds the prescribed time, the fast forward reproducing is continued and a setting sound is generated to notify the operator of the effect. Thus, if the operator wishes to transit to a fast forward reproducing from a reproducing condition, a quick transition to the fast forward reproducing process is accomplished by simply operating the button PLAY.

Is expanded under the control of the D / A converter 9
Is converted into an analog signal, amplified by the amplifier 10 and output from the speaker 11.

In step 204, the reproduction button PL
If AY has not been operated, it is determined in step 206 whether the fast forward button FF has been operated. Here, if the fast-forward button FF is operated, the fast-forward mode is set by the system control unit 6 in step 207, and the fast-forward process for fast-forwarding the operating position at an optimum speed (for example, 100 times the playback time) is executed. I do.

In step 206, the fast-forward button F
If F has not been operated, it is determined in step 208 whether the fast-return button REW has been operated. Here, fast reverse R
If the EW is operated, in step 209, the system control unit 6 sets the fast-return mode, and executes the fast-return process by moving the operating position in the direction opposite to that of the fast-forward described above.

If the fast-return button REW has not been operated in step 208, the process returns to step 202 and the same operation as described above is repeated. In addition, when the stop button STOP is operated during execution of each of the above-described recording, playback, fast-forward, and fast-reverse processing, or when the current operating position reaches the end position or the leading end position of the recording medium 7, the processing also ends. Then, the process returns to step 202.

Next, the reproduction process in such a main flow will be described in more detail. In this case, if the playback mode is set by the system control unit 6 by operating the playback button PLAY as described above, the flowchart shown in FIG. 3 is executed. In this case, in step 300, a reproduction process is executed. This reproduction processing is as described above. Next, in step 301, it is determined whether or not the playback button PLAY has been further operated during the playback processing. Here, if the play button PLAY is not operated, step 302
It is determined whether the stop button STOP has been operated, and the stop button ST

In step 302, a stop button STOP
If has not been operated, it is determined in step 304 whether the fast forward button FF has been operated. Here, fast forward button F
If F is operated, the CUE process is executed in step 305 while the fast-forward button FF is continuously operated. The CUE process is performed at a speed gradually increasing, for example, from 2 × speed to 4 × speed, 6 × speed, and 8 × speed every second, and then to 10 × speed after 5 seconds. Make a move. Then, when the operation of the fast-forward button FF is stopped in the CUE process, the determination in step 304 becomes NO, and the process returns to the normal reproduction process.

In step 304, the fast forward button F
If F has not been operated, it is determined in step 306 whether the fast-return button REW has been operated. If the fast-return button REW is operated, the REV process is executed in step 307 while the fast-return button REW is continuously operated. In the REV process, the operation position is moved in a direction opposite to that in the case of the CUE process.

If the fast-return button REW has not been operated in step 306, the end of the audio file is determined in step 308. If the end of the audio file has been reached, the process returns to the main flow shown in FIG. If not, it returns to step 301 and repeats the same operation as described above.

On the other hand, from the state of the reproduction processing, step 30
When the play button PLAY is operated in step 1, the step 309 is executed.
Then, the timer for measuring the time t during which the reproduction button PLAY is operated is started, and immediately in step 310, the reproduction speed is changed to the fast-listening reproduction process for reproducing at 1.5 times the normal speed.

Next, in steps 311, 312, it is determined whether or not the continuous operation of the play button PLAY ends before the set time t1. Here, if it is determined in step 312 that the continuous operation of the play button PLAY has ended before the set time t1, the timer is stopped in step 313, and in step 314,

FIG. 4 shows the flow of the pause PAUSE. In this case, in step 400, the pause is performed. Next, in step 401, it is determined whether the play button PLAY has been operated. Here, if the play button PLAY is operated, in step 402, the pause PAUSE is released, and the process returns to the flowchart shown in FIG. If the play button PLAY has not been operated in step 401, it is determined in step 403 whether the stop button STOP has been operated.
Then, the reproduction process is stopped, and the process returns to the main flow shown in FIG.

Also, in step 403, a stop button STOP
If has not been operated, it is determined in step 405 whether or not the fast forward button FF has been operated. Here, it is determined whether the fast-forward button FF has been operated. Here, fast forward button FF
If is operated, in step 406, the system control unit 6 sets a fast-forward mode, and executes a fast-forward process for fast-forwarding the operating position at an optimum speed (for example, 100 times the speed during playback).

In step 405, the fast-forward button F
If F has not been operated, it is determined in step 407 whether the fast-return button REW has been operated. Here, fast reverse R
If the EW is operated, in step 408, the system control unit 6 sets the fast-return mode, and executes the fast-return process by moving the operating position in the direction opposite to that of the fast-forward described above. Also in step 407, the fast-return button REW
If has not been operated, the process returns to step 401, and the same operation as described above is repeated.

Returning to the flowchart shown in FIG. 3, in step 311, continuous operation of the play button PLAY is performed for a set time t.
If it exceeds 1, it is determined in steps 315 and 316 whether or not the continuous operation of the play button PLAY ends before a predetermined time t2. Then, in step 316, a predetermined time t2
If it is determined in advance that the continuous operation of the play button PLAY has been completed, in step 317, the fast-reading playback is canceled and the process proceeds to the normal playback process. In step 318, the timer is stopped, and the process returns to step 302, where The operation after step 302 is executed.

On the other hand, at step 315, the reproduction button PLAY
If the continuous operation exceeds the predetermined time t2, it is determined that the fast-listening playback mode is to be continued, and in step 319, a set sound for notifying the operator is generated.
In step 8, the timer is stopped, the process returns to step 302, and the above-described operation after step 302 is executed.

FIG. 5 shows the relationship between the continuous operation time of the reproduction button PLAY and the operation mode switching. In this case, the operation time t of the reproduction button PLAY is shorter than the set time t1 as shown in FIG. If it is time, the process is shifted to playback PAUSE. If the time is longer than the set time t1 and shorter than the set time t2 as shown in FIG. If the time is longer than the set time t2, as shown in FIG.

Accordingly, in this way, when the user wants to perform the fast-listening playback from the playback state, the user can operate the playback button PLAY only to quickly shift to the fast-listening playback process. There is no need to consider the timing and timing, and there is no uncomfortable feeling in operation, and excellent operability can be obtained.

Further, by continuing to operate the play button PLAY for a predetermined time or more, the quick-hearing reproduction process can be continuously executed, so that the usability is further improved with respect to the use in which the quick-hearing reproduction is prioritized. it can.

In the above-described embodiment, the playback PAUSE
And the determination time for continuously setting the fast-listening playback mode are different from t1 and t2. This is to increase the degree of freedom in design. t1 = t2 may be set. In this case, an advantage that control can be simplified can be expected. In addition, since the fast listening mode is set before the pause, there is a possibility that a sense of incongruity may occur. However, the fast listening mode is set to about 1.5 times the normal playback speed, and t1 is several tens of ms.
Since this is set to about several hundred ms, even if the reproduced sound is output during this time t1, this short reproduced sound is hardly perceived by humans, so that the pause can be set without discomfort. (Second Embodiment) In the first embodiment, once the reproduction button PLAY is operated from the state of the reproduction processing to switch to the fast-listening reproduction processing, the reproduction is stopped in order to return to the normal reproduction processing. The button STOP must be operated to temporarily stop the processing of the apparatus. However, in the second embodiment, from the state of the fast listening reproduction processing, only the reproduction button PLAY is operated, and the normal reproduction is performed again. It can be switched to processing.

In this case, FIG. 1 shows a schematic configuration of the audio reproducing apparatus, FIG.
The flow in USE is the same as that in FIG. 4, and the description will be omitted with reference to these drawings.

The operation after step 602 described above under the fast listening reproduction process is executed.

Next, when the play button PLAY is operated in step 601 from the state of the fast listening playback processing, in step 609, a timer for measuring the time t during which the play button PLAY is operated is started. At 610, it is determined whether the current state is a playback state or a fast listening playback state. In this case, the current state is the fast-listening playback processing, so that the normal playback is changed in step 618, and the playback button PL is changed in steps 612 and 613.
It is determined whether the continuous operation of AY ends before the set time t1. Then, if the continuous operation of the play button PLAY exceeds the set time t1 in step 612, this time, assuming that normal playback processing is to be performed, a set sound for notifying the operator of this is generated in step 616. Then step 61
In step 7, the timer is stopped, and the process returns to step 602, and the operations after step 602 under the normal reproduction process are executed.

FIG. 7 shows the relationship between the continuous operation time of the reproduction button PLAY and the operation mode switching. In this case, as shown in FIG. 7A, the operation time t of the reproduction button PLAY is shorter than the set time t1. If it is time, it is shifted to playback PAUSE, and if it is a time longer than the set time t1, as shown in FIG.
Alternatively, the process is shifted from the fast listening playback process to the normal playback process.

Therefore, by operating the play button PLAY from the state of the playback processing to switch to the fast-listening playback mode, the user only operates the play button PLAY again.
Normal playback processing can be switched, and the playback button PLAY
