  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A. First embodiment A-1. Configuration of First Embodiment FIG. 1 is a block diagram showing a configuration of a data recording / reproducing apparatus according to a first embodiment of the present invention. In the figure, an audio signal processing unit 1 takes in audio from a microphone 2, converts it into a digital signal and supplies it to the central control unit 10, while converting the audio signal into an analog signal and outputs it from a speaker 3. The operation unit 4 inputs various data, operation instructions, and the like. The display unit 5 includes a liquid crystal display and displays information such as data recording time and data reproduction time, various messages, and the like. In particular, in the present embodiment, as shown in FIG. 3, at the end of recording, a message for prompting the user to play back the recorded voice data as it is is displayed.

  When the RTC 6 records (records) audio data, it measures the actual time for acquiring the date and time. The fingerprint acquisition unit 7 reads the user's fingerprint when recording audio data or reproducing audio data. The ROM 8 stores predetermined programs and various parameters. The RAM 9 stores various data. In particular, in the present embodiment, a data storage unit 9-1 is provided, and as shown in FIG. 2, an ID for identifying recorded audio data, recorded data (audio data), recording time, last reproduction time, Stores the number of playbacks and fingerprint data.

  The central control unit 10 controls each unit according to a predetermined program stored in the ROM 8 described above. In particular, in the present embodiment, the central control unit 10 controls recording, reproduction, and deletion of audio data according to the user's fingerprint acquired by the fingerprint acquisition unit 7.

A-2. Operation of First Embodiment Next, the operation of the first embodiment described above will be described. FIG. 4 is a flowchart for explaining the operation of the data recording / reproducing apparatus according to the first embodiment. Prior to recording, first, it is determined whether or not the user's fingerprint (any one of the ten fingerprints in total) is acquired (step S10). If the fingerprint acquisition unit 7 has acquired the user's fingerprint (any one of the ten fingerprints on the left and right), the voice data associated with the acquired fingerprint has already been stored in the data storage unit 9-1. It is determined whether it is stored (step S12).

  If there is no audio data associated with the acquired fingerprint, recording is started (step S14), and it is determined whether or not recording has ended during recording, that is, whether or not there has been an operation for ending recording. Judgment is made (step S16). When the recording is completed, the recording data, fingerprint data, recording time, etc. are stored in the data storage unit 9-1 of the RAM 9 as shown in FIG. 2 (step S18). Next, as shown in FIG. 3, a playback confirmation message is displayed on the display unit 5 (step S20), and it is determined whether or not an end operation has been performed (step S22). Ends the processing.

  On the other hand, when the end operation is not performed, it is determined whether the fingerprint of the user has been acquired by the fingerprint acquisition unit 7 according to the reproduction confirmation message (step S24). Then, it is determined whether or not the fingerprint acquired in step S10 at the start of recording matches the fingerprint acquired in step S24 after the end of recording (step S26). That is, when the user reproduces the recording data immediately after the end of recording, the user may input the same fingerprint as that at the start of recording. If the two fingerprints do not match, the process ends.

  On the other hand, if both fingerprints match, reproduction of the recorded data is started (step S32), and during reproduction, whether reproduction has ended, that is, whether reproduction of the recorded data has been completed, or the user 2 determines whether or not the reproduction has been stopped (step S34), and when the reproduction is completed, the number of reproductions shown in FIG. 2 for the recorded data is updated (step S36), and the current value obtained from the RTC 6 is updated. The last reproduction time is updated according to the time (step S38), and the process is terminated.

  If the audio data associated with the fingerprint is already stored in the data storage unit 9-1 in step S12, the current time is acquired from the RTC 6 (step S28), and the recording time of the corresponding recording data is acquired. Is determined within 30 days (step S30). When the recording time of the recording data is within 30 days (recently recorded), the process proceeds to the above-described step S32 and after, the reproduction of the recording data is started, and when the reproduction ends, the number of reproductions is set. In addition to updating, the last reproduction time is updated according to the current time acquired from the RTC 6, and the process is terminated.

  On the other hand, if the recording time is not within 30 days, it is determined whether or not the last playback time is 20 days or more before (step S40). Even if the recording time exceeds 30 days, the final playback time is 20 days. If it is not more than a day ago (reproduced recently), the process proceeds to the above-described step S32 and thereafter, and the reproduction of the recorded data is started. When the reproduction is finished, the number of reproductions is updated and the current acquired from the RTC 6 The last reproduction time is updated according to the time, and the process ends.

  If the last playback time is more than 20 days ago (not recently played), it is determined whether the number of playbacks is 2 or less (whether it is not played back frequently) (step). S42) Even if the recording time exceeds 30 days and the final reproduction time is more than 20 days ago, if the number of reproductions is more than two, the process proceeds to the above step S32 and the recorded data is reproduced. When the reproduction is finished, the number of reproductions is updated according to the current time acquired from the RTC 6, and the final reproduction time is updated, and the process ends.

  On the other hand, if the recording time exceeds 30 days, the last playback time is more than 20 days ago, and the number of playbacks is 2 times or less, it is recorded quite a long time ago and frequently played back recently. It is determined that there is no deletion, a message for confirming the deletion is displayed on the display unit 5 (step S44), and it is determined whether or not the user has performed a deletion operation (step S46). If there is no deletion operation by the user, the process ends without deleting the recording data. On the other hand, if there is a deletion operation by the user, the recording data is deleted (step S48), and the process ends.

  In the first embodiment described above, when the user wants to record audio data, the device recognizes his / her fingerprint that has not been used at the time of recording, records the audio data, and the user wants to reproduce the audio data. Because the fingerprint that was recognized by the device when the voice data was recorded was made to be recognized again by the device and the voice data was reproduced, the voice data can be easily recorded simply by making the device recognize the fingerprint. Or play.

  For example, when recording the first audio data, the right hand thumb is determined for the second recording, the right index finger is determined for the second recording, and the audio data is recorded in correspondence with the fingerprint of the finger, and the first audio data is recorded for reproduction. Can be easily reproduced by recognizing the fingerprint of the right index finger.

  In addition, since fingerprints are used as biometric information for identifying individuals, they are not reproduced by a third party.

  In addition, it is possible to delete audio data that has passed a predetermined period of time since recording and that has passed a predetermined period of time since the last playback and whose number of playbacks is less than or equal to the predetermined number of times by an easy operation. It becomes possible to use the fingerprint associated with the item when recording different audio data.

B. Second Embodiment Next, a second embodiment of the present invention will be described. The configuration of the data recording / reproducing apparatus is the same as that shown in FIG. In the second embodiment, as shown in FIG. 5, the recording and reproduction of audio data are controlled by associating a combination of two fingerprints with recording data, such as a first fingerprint and a second fingerprint. It is characterized by. The fingerprints to be combined may be of the same finger or different fingers.

B-1. Operation of Second Embodiment Next, the operation of the second embodiment will be described. FIG. 6 is a flowchart for explaining the operation of the data recording / reproducing apparatus according to the second embodiment. Prior to recording, it is first determined whether or not the user's first fingerprint has been acquired (step S60). When the fingerprint acquisition unit 7 acquires the first fingerprint of the user (any one of the ten fingerprints on the left and right), it is next determined whether or not the second fingerprint of the user has been acquired ( Step S62). When the user's second fingerprint (any one of the ten fingerprints in total) is acquired by the fingerprint acquisition unit 7, the voice associated with the combination of the first fingerprint and the second fingerprint It is determined whether or not the data is already stored in the data storage unit 9-1 (step S64).

  If there is no audio data associated with the acquired first fingerprint and second fingerprint, recording is started (step S66), and whether or not recording has ended during recording, that is, recording It is determined whether or not an end operation has been performed (step S68). When the recording is completed, the recording data, the first fingerprint data, the second fingerprint data, the recording time, etc. are stored in the data storage unit 9-1 of the RAM 9 as shown in FIG. 5 (step S70). The process ends.

  On the other hand, when the audio data associated with the acquired first fingerprint and second fingerprint is already stored in the data storage unit 9-1, reproduction of the recorded data is started (step S72). During playback, it is determined whether or not playback has ended, that is, whether or not playback of recorded data has been completed, or whether or not playback has been stopped by the user (step S74). 5 is updated for the recorded data (step S76), and the final playback time is updated according to the current time acquired from the RTC 6 (step S78), and the process is terminated.

  In the second embodiment described above, by associating a plurality of fingerprints with one voice data, only one fingerprint data can be recorded / reproduced when only one fingerprint is associated with one voice data. On the other hand, a large number of audio data can be recorded / reproduced with an easy operation. For example, it is possible to record and play back more than 10 voice data with easy operations, such as the right thumb fingerprint and index finger fingerprint data, and the right thumb and middle finger fingerprint data separate. .

B-2. First Modification Next, a first modification of the above-described second embodiment will be described. In the first modification, recording and reproduction of audio data are managed and controlled in accordance with the number of fingerprints acquired within a predetermined time. Therefore, in the first modified example, as shown in FIG. 7, recording data (voice data) is associated with the number of times of fingerprint acquisition.

  Next, the operation of the first modification of the second embodiment will be described. FIG. 8 is a flowchart for the operation of the first modification of the second embodiment. Prior to recording, first, it is determined whether or not the user's fingerprint (any one of ten fingerprints in total) is acquired (step S90). Then, when the fingerprint acquisition unit 7 acquires the user's fingerprint (any one of the ten fingerprints on the left and right), the number of acquisition is set to “1” (step S92), and time measurement by the acquisition timer is started (step S94). ).

  Next, it is determined again whether or not the user's fingerprint has been acquired (step S96). If the user's fingerprint is not acquired, it is determined whether or not the acquisition timer has timed out (step S100). If the user has not timed out, the process returns to step S96 to repeat the fingerprint acquisition. On the other hand, if a fingerprint is acquired before the acquisition timer times out, the number of acquisitions is incremented by “1” each time (step S98).

  Then, when the acquisition timer times out, the time measurement by the acquisition timer is ended (step S102). By the series of processing (fingerprint acquisition processing) in steps S90 to S102 described above, the user's fingerprint is acquired a plurality of times before the acquisition timer times out.

  Next, it is determined whether or not the voice data associated with the acquired fingerprint is already stored in the data storage unit 9-1 (step S104). If there is no audio data associated with the acquired fingerprint, recording is started (step S106), and it is determined whether or not recording has ended during recording, that is, whether or not there has been a recording end operation. Judgment is made (step S108). When the recording is completed, the recording data, fingerprint data, recording time, number of times of acquisition, etc. are stored in the data storage unit 9-1 of the RAM 9 as shown in FIG. 7 (step S110), and the process ends.

  On the other hand, if the voice data associated with the acquired fingerprint is already stored in the data storage unit 9-1, it is determined whether there is voice data that also has the same number of acquisitions (step S112). If the number of acquisition times does not match, the process proceeds to the above-described step S106 and thereafter, recording is started, and when the recording is completed, the recording data, fingerprint data, recording time, number of acquisitions, etc. are stored in the data storage unit 9- 1 and the process is terminated.

  On the other hand, if there is audio data associated with the acquired fingerprint and the number of acquisitions also matches, playback of the recorded data is started (step S114), and whether or not playback has ended during playback. That is, it is determined whether or not the reproduction of the recorded data has been completed, or whether or not the reproduction has been stopped by the user (step S116), and when the reproduction is completed, the number of reproductions shown in FIG. Is updated (step S118), and the final playback time is updated according to the current time acquired from the RTC 6 (step S120), and the process is terminated.

  In the first modification described above, it is possible to record / reproduce 10 or more pieces of audio data with a simple operation, such as the right thumb fingerprint twice for this audio data and the third time for another audio data. become. When voiceprints are used as biometric information instead of fingerprints, this voice data is used when “a, a” is spoken twice, and another voice data is used when “a, a, a” is spoken three times. It is possible to record / reproduce a larger number of audio data by distinguishing them.

B-3. Second Modification Next, a second modification of the second embodiment described above will be described. In the second modification, recording and reproduction of audio data are controlled according to the fingerprint acquisition time (pressing time on the fingerprint acquisition unit). Therefore, in the second modified example, as shown in FIG. 9, the recording data (voice data) is associated with the fingerprint acquisition time.

  Next, the operation of the second modification of the second embodiment will be described. FIG. 10 is a flowchart for the operation of the second modification of the second embodiment. Prior to recording, first, it is determined whether or not the user's fingerprint (any one of ten fingerprints in total) is acquired (step S140). When the fingerprint acquisition unit 7 acquires the user's fingerprint (any one of the ten fingerprints in total, left and right), the time measurement by the acquisition timer is started (step S142).

  Next, it is determined whether or not the fingerprint acquisition is completed, that is, whether or not the user has released the finger for inputting the fingerprint (step S144), and the time measurement by the acquisition timer is continued until the user releases the finger. To do. Then, when the user lifts the finger and the fingerprint acquisition is completed, the time measured by the acquisition timer at that time, that is, the fingerprint acquisition time is stored in the data storage unit 9-1 of the RAM 9 as shown in FIG. Step S146), the time counting by the acquisition timer is ended (Step S148).

  Next, it is determined whether or not the voice data associated with the acquired fingerprint is already stored in the data storage unit 9-1 (step S150). If there is no audio data associated with the acquired fingerprint, recording is started (step S152), and it is determined whether or not recording has ended during recording, that is, whether or not there has been an operation for ending recording. Judgment is made (step S154). When the recording is completed, the recording data, fingerprint data, recording time, acquisition time, and the like are stored in the data storage unit 9-1 of the RAM 9 as shown in FIG. 9 (step S110), and the process ends.

  On the other hand, if the voice data associated with the acquired fingerprint has already been stored in the data storage unit 9-1, it is determined whether there is voice data that has the same acquisition time (step S158). If the acquisition times do not match, the process proceeds to the above-described step S152 and thereafter, recording is started, and when the recording is completed, the recording data, fingerprint data, recording time, acquisition time, etc. are stored in the data storage unit 9- 1 and the process is terminated.

  On the other hand, if there is audio data associated with the acquired fingerprint and the acquisition times match, reproduction of the recorded data is started (step S160), and whether or not reproduction has ended during reproduction That is, it is determined whether or not the reproduction of the recorded data has been completed, or whether or not the reproduction has been stopped by the user (step S162). When the reproduction is completed, the number of reproductions shown in FIG. Is updated (step S164), and the final playback time is updated according to the current time acquired from the RTC 6 (step S166), and the process is terminated.

  In the second modification described above, the fingerprint acquisition time (press on the fingerprint acquisition unit) is used, such as when the user applies a finger to the device for a short time, this audio data, and when the user applies a long time, another audio data. By controlling the recording and reproduction of the audio data according to time, it becomes possible to record and reproduce a larger number of audio data.
