BACKGROUND OF THE INVENTION
The present invention relates to a recording / reproducing apparatus capable of recording audio as an audio file and reproducing the audio file at a set time.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a recording / reproducing apparatus (hereinafter referred to as “IC recorder”) including a flash memory that stores an audio signal for each file is provided. The IC recorder has a function (alarm setting function) for recording a sound signal file (hereinafter referred to as “sound file”) and for reproducing the sound file at a predetermined time. When setting the alarm, the user shifts the IC recorder to the alarm setting mode by a predetermined operation, and inputs the date and time for reproducing the desired audio file.
[0003]
[Problems to be solved by the invention]
By the way, there are cases where the user wants to confirm the content of the alarm setting. However, in the conventional IC recorder, the user cannot confirm the contents of the alarm setting unless the alarm setting mode is entered at this time.
[0004]
Here, an example of operation when the user confirms the contents when the alarm is already set will be described. For example, the IC recorder enters the alarm on / off mode when the menu button is pressed once, enters the date day selection mode when pressed once, and enters the date / time setting mode when pressed once more. When the date / time setting mode is entered, the alarm-set date and time are displayed.
[0005]
Therefore, the user needs to press the menu button at least three times to confirm the contents. That is, the user needs to perform the above operation to confirm the contents of one alarm setting, and further, as the number of cases increases, it becomes necessary to perform another operation. It becomes very difficult.
[0006]
The present invention has been proposed in view of such a situation, and provides a recording / reproducing apparatus capable of confirming the contents by an easy operation in advance even when the number of alarms set is large. Objective.
[0007]
[Means for Solving the Problems]

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The present invention is applied to, for example, an IC recorder 1 configured as shown in FIG.
[0010]
The IC recorder 1 stores audio data in an EEPROM (Electrical Erasable / Programmable Read-Only Memory), that is, a flash memory 9, which is a non-volatile memory that can be electrically erased / rewritten by the recording unit 10 and flashed. It has a control unit 30 that controls the reproduction of the audio data in the memory 9 by the reproduction unit 20, and displays the operation content from the operation unit 50 and the content of the audio data in the flash memory 9 on the display unit 40. The flash memory 9 stores audio data as one audio file for each case.
[0011]
The recording unit 10 converts a sound into an electric signal and outputs a sound signal, an amplifier 12 that amplifies the sound signal from the microphone 11, and gain control of the sound signal amplified by the amplifier 12. An automatic gain control circuit (hereinafter referred to as “AGC”) 13 for performing, an encoder 14 for converting a sound signal from the AGC 13 into sound data, and a buffer memory 15 for temporarily storing the sound data from the encoder 14. Is provided.
[0012]
The microphone 11 converts the input sound into an audio signal and supplies it to the amplifier 12. The amplifier 12 amplifies the audio signal and supplies it to the AGC 13. The AGC 13 performs gain control so that the gain of the audio signal amplified by the amplifier 12 becomes a predetermined value, and supplies the audio signal to the encoder 14.
[0013]
Since the audio signal has a strong correlation in time, the encoder 14 encodes the audio signal by, for example, an adaptive differential pulse code modulation (hereinafter referred to as “ADPCM”) method to convert the audio data. The audio data is generated and supplied to the flash memory 9 via the buffer memory 15 and the control unit 30.
[0014]
Further, the encoder 14 can adjust the encoding amount of the audio data according to two modes. For example, the sampling is performed at 8 kHz in the SP mode, and the sampling is performed at 4 kHz in the LP mode. The encoding amount of the audio signal is adjusted with respect to the direction.
[0015]
Here, the flash memory 9 has a file storage area that is an area for storing an audio file from the recording unit 10 and a reproduction time storage area that is an area for storing the reproduction time of each audio file. Further, the user can operate the operation unit 50 to select a desired one from the sound files already stored in the flash memory 9 and set the time for reproducing the sound file. At this time, the flash memory 9 also stores data indicating the playback time of the audio file in the playback time storage area.
[0016]
There are two types of audio files: LP mode recorded in the long-time recording mode and SP mode recorded in the normal mode, which are distinguished by the sampling frequency at the time of recording. Also, all audio files are recorded by being distinguished as any one of A file, B file, and C file. The A file, B file, and C file can be preset by the user by operating the operation unit 50 before recording the audio file, and the audio file is classified and recorded as one of the set A files or the like. Is done.
[0017]
On the other hand, the reproducing unit 20 includes a decoder 21 that converts audio data read from the flash memory 9 via the control unit 30 into an original audio signal, a filter 22 that removes high-frequency components, and audio from the filter 22. And an amplifier 23 that amplifies the signal and supplies the amplified signal to the speaker 24.
[0018]
The decoder 21 corresponds to the encoder 14 of the recording unit 10 and decodes the audio data read from the flash memory 9 according to the SP mode or LP mode, that is, the audio data encoded by the ADPCM method. Thus, a so-called PAM signal is generated. The filter 22 removes a high frequency component of the voice band or higher from the PAM signal and outputs a voice signal. The amplifier 23 amplifies the audio signal supplied from the decoder 21 and drives the speaker 24. Thus, the recorded sound is output from the speaker 24.
[0019]
The control unit 30 executes a ROM 31 in which a program for controlling the operation of the IC recorder 1 is stored and a program stored in the ROM 31 to execute the flash memory 9, the recording unit 10, the playback unit 20, and the display. A microcomputer (hereinafter referred to as “CPU”) 32 for controlling the unit 40, a timer 33 for generating time information, and a random access memory (hereinafter referred to as “the time of execution of a program”). RAM ”: Random Access Memory) 34 and controls each circuit based on the operation setting of the operation unit 50.
[0020]
The RAM 34 stores, for example, TOC (Table Of Contents) information read from the flash memory 9 at the time of activation, time data for reproducing an audio file, and the like. Then, the CPU 32 compares the reproduction time data stored in the RAM 34 with the time information of the timer 33, and reproduces the audio file when they match.
[0021]
The display unit 40 includes a low power consumption liquid crystal display panel 41 and a backlight 42 for illuminating the liquid crystal display panel 41, and displays the operation state and operation procedure of the IC recorder 1. The liquid crystal display panel 41 displays, for example, “S” when a later-described special file is stored in the flash memory 9, and alerts the user that the special file has already been stored.
[0022]
The appearance of the IC recorder 1 is shown in FIG. The IC recorder 1 is configured to be covered with a substantially rectangular parallelepiped housing 60 that is large enough to be held with one hand. A display unit 40 is provided on the front surface 60 a of the housing 60. In addition, the housing 60 includes a send / return button 51 for selecting the next or previous audio file of the displayed audio file, and a playback button 52 for starting playback of the audio file as the operation unit 50 described above. A stop button 53 for stopping the audio file being reproduced, an alarm button 54 for displaying an alarm, and a button for setting the time (not shown).
[0023]
A feed / return button 51 and a play button 52 are provided on the side surface 60 b of the housing 60. The feed / return button 51 is configured such that its upper end 51a or lower end 51b can be pressed. The user can select a desired audio file by pressing the upper end 51a or the lower end 51b. When the play button 52 is pressed, the selected audio file is played, and when the stop button 53 is pressed, the playback of the audio file is stopped.
[0024]
The IC recorder 1 having such a configuration can record an audio signal for each case as an audio file, and sets the time for reproducing the audio file as described above (hereinafter referred to as “alarm setting”). ) Is also possible.
[0025]
For example, the user can set the month, date, and time for playing a desired audio file once (month and day setting), or can set to play at a predetermined time on a predetermined day of the week (set weekly), It is possible to make a setting (daily setting) for playback at a predetermined time every day.
[0026]
Next, a method for searching the alarm-set content will be described by exemplifying the alarm-set content. Here, it is assumed that the user sets alarms for the first to fourth requirements as follows.
[0027]
First requirement (No. 1)
Play the 2 / 6th audio file of the C file at 8:00 every day Second requirement (No. 2)
Play the 1 / 4th audio file of file B at 8:20 on October 20th Third requirement (No. 3)
The 8 / 12th audio file of the A file is played every Wednesday at 18:00 The fourth requirement (No. 4)
Play 4 / 6th audio file of C file at 17:30 on Oct. 15
Then, when the user presses the alarm button 54, the CPU 32 performs the processing after step S1 shown in FIG.
[0029]
In step S <b> 1, the CPU 32 determines the presence / absence of an alarm-set message. Specifically, it is determined whether there is an audio file with an alarm set in the flash memory 9, and if it exists, the process proceeds to step S2, and if it does not exist, the process proceeds to step S9. Specifically, the CPU 32 determines whether an audio file is stored in the flash memory 9 and, if an audio file is stored, data indicating the reproduction time is also stored. Then, the CPU 32 proceeds to step S9 when no audio file is stored in the flash memory 9 or when it is determined that no data indicating the reproduction time is stored in any audio file, and otherwise, the step 32 Proceed to S2.
[0030]
In step S2, the CPU 32 displays “AL SCHEDULE” on the liquid crystal display panel 41 for 1 second, then blinks the alarm mark, and proceeds to step S3.
[0031]
In step S3, the CPU 32 determines the priority order among the alarm-set audio files, selects the audio file with the highest priority, and proceeds to step S4.
[0032]
Here, an algorithm for determining the priority order will be described.
It is assumed that the audio file with the alarm set has a high priority in the order of the month / day setting, weekly setting, and daily setting. When there are a plurality of audio files for the month / day setting, weekly setting, and daily setting, it is assumed that the priority is higher from the closest to the current time. Under such priorities, for example, eight audio files shown in FIG. 4A are rearranged as follows. The numbers from 1 to 8 indicate the priority, the priority 1 is the highest, and the priority 8 is the lowest.
[0033]
First, as shown in FIG. 4B, one audio file (priority 5 in this case) is designated at random. Based on this designated priority 5 audio file, those having a higher priority than this audio file are divided to the left, and those having a lower priority than this audio file are divided to the right. As a result, as shown in FIG. 4C, the audio files 4, 2, 3, and 1 are sorted on the left side, and the audio files 8, 7, and 6 are sorted on the right side.
[0034]
Next, as shown in FIG. 4 (D), one audio file is randomly specified from the left and right audio file groups, except for the reference priority 5 audio file. Here, an audio file with priority 3 is designated from the left audio file group, and an audio file with priority 7 is designated from the right audio file group.
[0035]
In each audio file group, with the designated audio file as a reference, those having a higher priority than this audio file are divided on the left side, and those having a lower priority than this audio file are divided on the right side. As a result, as shown in FIG. 4E, in the audio file group on the left side, the audio files 2 and 1 are sorted on the left side and the audio file 4 is sorted on the right side with respect to the audio file of priority 3. Is done. In the right audio file group, the audio file 6 is sorted on the left side and the audio file 8 is sorted on the right side with respect to the audio file having the priority level 7.
[0036]
Finally, an audio file (here, an audio file with priority 1) is randomly specified from audio files 2 and 1 and sorted based on the priority. As a result, as shown in FIG. 4F, the audio files having the priority levels 1 to 8 are sorted in descending order of priority.
[0037]
When the CPU 32 sorts the above-described first to fourth requirements according to such an algorithm, the fourth requirement, the second requirement, the third requirement, the first requirement, in descending order of priority. The priority order is determined by rearranging the requirements. Then, the audio file with the highest priority is designated, and the process proceeds to step S4. Note that the sorting algorithm is not limited to that described above, and other methods may be used. For example, by using a so-called bubble sort method, the priorities of adjacent audio files may be compared and determined in order from the lowest priority or the highest priority.
[0038]
In step S4, the CPU 32 displays the alarm-set message (set date / time). That is, the alarm setting date and time of the designated audio file is displayed on the display unit 40, and the process proceeds to step S5. For example, when the fourth priority audio file having the highest priority is designated, the CPU 32 displays the 4 / 6th audio file of the C file on the display unit 40 as shown in FIG. In addition, “10 ^M 18 ^D 17:30”, which is the reproduction time, is also displayed.
[0039]
In step S <b> 5, the CPU 32 determines what operation is performed on the operation unit 50. When the play button 52 is pressed, the process goes to step S6, when the upper end part 51a of the forward / return button 51 is pressed, to step S7, and when the lower end part 51b of the forward / return button 51 is pressed, the process goes to step S6. When the stop button 53 is pressed in S8, the process ends.
[0040]
In step S6, the CPU 32 reproduces the alarm-set message. Specifically, the audio file displayed in step S4 is read from the flash memory 9 and reproduced via the reproduction unit 20, and as shown in FIG. 6, the date when the audio file was stored in the display unit 40 is displayed. “10 ^M 15 ^D 20:40” is displayed, and the process returns to step S3.
[0041]
On the other hand, in step S7 when it is determined in step S5 that the upper end portion 51a of the send / return button 51 has been pressed, the CPU 32 designates an audio file that is fed one step, that is, one that is lower in priority, and step S3. Return to. For example, if the upper end portion 51a of the send / return button 51 is pressed when the fourth business audio file is specified, the second business audio file is specified. At this time, when the process returns to step S3 via step S7, the CPU 32 displays the fourth audio file of the B file on the display unit 40 in order to suggest the second requirement as shown in FIG. At the same time, “10 ^M 20 ^D 11:30” which is the reproduction time is displayed.
[0042]
Further, when the upper end 51a of the send / return button 51 is pressed, as shown in FIG. 8, the third requirement audio file that is played every Wednesday at 18:00 is displayed. When the upper end 51a is pressed again, as shown in FIG. 9, the first requirement audio file that is played at 8:00 every day is displayed.
[0043]
On the other hand, in step S8 when it is determined in step S5 that the lower end portion 51b of the feed / return button 51 has been pressed, the CPU 32 designates an audio file that is returned by one, that is, one higher priority, and goes to step S3. Return.
[0044]
For example, when the lower end portion 51b of the send / return button 51 is pressed when the first business audio file is specified, the third business audio file is specified. At this time, when returning to step S3 via step S8, the CPU 32 displays the third message, which is the 8 / 12th audio file of the A file, on the display unit 40 as shown in FIG. At the same time, “WED 18:00” which is the reproduction time is displayed.
[0045]
Further, when the lower end 51b of the feed / return button 51 is pressed, the second requirement audio file is displayed as shown in FIG. 7, and when it is pressed again, as shown in FIG. The audio file of 4 messages is displayed.
[0046]
Further, in step S9 when it is determined that there is no audio file set with an alarm in step S1, the CPU 32 displays “NO AL SCHEDULE” on the display unit 40 for one second, and the audio file set with the alarm is displayed. The process is terminated by suggesting to the user that there is not, and the normal recording / playback mode is set.
[0047]
As described above, the IC recorder 1 can easily confirm the audio file set with an alarm in advance without performing troublesome operations many times. Moreover, since it is automatically displayed from a relatively important message, the user can check the contents of the alarm setting from the important message.
[0048]
The IC recorder 1 determines the priority order in the order of month / day setting, weekly setting, and daily setting in the processing of step S3 described above, but for example, the priority order is determined in the order closest to the current time. Also good.
[0049]
At this time, the CPU 32 sorts the contents of the alarm setting items in descending order of the current time by specifically performing the processing from step S11 shown in FIG.
[0050]
In step S11, the CPU 32 acquires the current date / time (date / time) from the time information of the timer 33, and proceeds to step S12.
[0051]
In step S12, the CPU 32 compares the current date with the alarm setting date of each audio file, and proceeds to step S13.
[0052]
In step S <b> 13, the CPU 32 sorts the audio files of the business for which the alarm is set by date, and proceeds to step S <b> 14.
[0053]
In step S14, the CPU 32 compares the time when there is an audio file with the same date among the audio files with the alarm setting, and proceeds to step S15.
[0054]
In step S15, the CPU 32 sorts audio files with the same date in order of time, and ends the process.
[0055]
The CPU 32 can determine the priority order by sorting the audio files set with alarms in the order of date and time by performing the processing as described above. Here, Table 1 shows priorities when the above-mentioned first to fourth items are sorted in the order of date and time.
[0056]
[Table 1]

[0057]
At this time, each time the user presses the upper end portion 51a of the forward / return button 51, each item in Table 1 is displayed on the display unit 40 one by one from top to bottom. Conversely, each time the user presses the lower end 51b of the send / return button 51, each item in Table 1 is displayed one by one from the bottom to the top. In the case of weekly setting or daily setting, the alarm setting contents are displayed as much as possible. For example, only the contents one month ahead may be viewed.
[0058]
As described above, the IC recorder 1 can also display the contents of the alarm setting in the order from the current time, so that the user can easily check the order from the current time.
[0059]
In the above-described embodiment, the example in which the contents of the alarm setting are displayed one by one on the display unit 40 has been described. However, information on several audio files can be displayed at one time. At this time, when the user presses the upper end portion 51a or 51b of the forward / return button 51, the display content on the display unit 40 may be scrolled in a lower or higher priority order.
[0060]
【The invention's effect】
As described above in detail, according to the recording / reproducing apparatus of the present invention, when the second operation means is operated, each audio is based on the reproduction time of each audio file for which the reproduction time is set. By determining the priority of the file and displaying the information of the audio file on the display means in the order of the priority, even if the number of alarms set is large, the contents can be changed by simply operating the operation means. It can be easily confirmed in advance.
