Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio recording device, and more particularly to an audio recording device that converts an analog signal into a digital signal and records the digital signal on a recording medium.

[0002]

2. Description of the Related Art Conventionally, in a so-called dictation system in which a typist reproduces and records contents recorded by a plurality of recorders, a so-called dictation system, an analog recording system using a conventional small cassette tape which is widely used. In this method, a typist could identify who recorded the music by writing the name of the recorder on a cassette tape, or by recording the name at the beginning of the recorded content.

In a central system in which dictation is recorded directly on a typist's playback device through a telephone line or the like, a number predetermined for each dictator is input before starting dictation on a telephone. On the other hand, a means has been used in which the reproducing apparatus specifies the recorder.

On the other hand, in recent years, an audio signal obtained by a microphone or the like is converted into a digital signal and recorded on a recording medium such as a semiconductor memory, for example. There has been proposed a digital audio recording / reproducing apparatus called a so-called digital recorder which converts the audio into audio data from a speaker or the like.

In such a voice recording / reproducing apparatus such as a digital voice recording / reproducing apparatus, the name of a recorder is recorded at the beginning of each sentence. Further, in a system of the central system, a predetermined number or the like is input when audio data is transferred to a reproducing device on the typist side, and this is added as information of each data file.

However, in the above-described dictation-type recording, the technical means for identifying an orator by writing a name on a cassette tape does not always return the person who has written the name after the typist finishes typing.
While repeating the dictation several times, it is registered under the name of another person, and there is a possibility that an error such as billing may occur.

[0007] In addition, in the method of speaking a name or a number before registration, it is troublesome to perform the recording every time recording is performed.

In view of such a problem, the present applicant has previously proposed a voice recording / reproducing apparatus for assigning an appropriate identification code to voice data in Japanese Patent Application No. 8-10441.

This audio recording / reproducing apparatus provides a dictation / transcription in which a recording medium recorded by a plurality of recorders is typed while one or more typists (or transcriptionists) play the content. In order to identify a recording person, index information including a user ID code is recorded when recording a voice.

[0010] In addition, a function is provided for the typist to read and display the user ID code when reproducing the recording medium, so that the recorder can be easily identified.

Further, in a system in which voice data with index information is taken into a personal computer and processed, applied technical means such as sorting and managing voice data for each user have been proposed.

[0012]

As described above, the technical means proposed in Japanese Patent Application No. 8-10441 is very useful. However, in the technical means, as a method of setting a user ID code, only a method of setting by user's button operation is proposed. For this reason, when a single recording / reproducing device is shared by a plurality of recorders, or when one recorder uses a plurality of recording / reproducing devices, the user operates a button each time to execute the user ID. There was room for improvement, such as the need to reset the code.

When the system backup battery is replaced, the system is reset and the user ID is reset.
Since the memory of the code is lost, it is necessary to reset the user ID code in the same manner as described above, and there is room for improvement.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a voice recording apparatus in which a user ID code can be easily set.

When the user intends to set an arbitrary user ID code, this is performed by operating the ID code setting operation section 13. ID code setting operation unit 13
Are three buttons, that is, a first operation button (SE
T) 13a, a second operation button (SEL) 13b, and a third operation button (MENU) 13c. In the present embodiment, these three buttons are independently provided as the ID code setting operation unit 13. However, the present invention is not limited to this.
The buttons in the operation input unit 19 may be used in combination.

In this embodiment, the mode is set in which the user ID code is set by holding down the third operation button (MENU) 13c for two seconds. At this time, for example, when the recording medium 7 composed of a memory card is not mounted, the current user ID code is displayed on the display unit 12 and the four-digit ID is displayed.
The character at the top digit of the code flashes to indicate that the character or the like at that portion can be changed.

FIG. 5 shows an example in which the current user ID code is "AAAAA" (same as the default value) on the display unit 12 and the leftmost character or the like can be changed. It is a front view.

From this state, the first operation button (SET) 1
When 3a is pressed, each time the character is pressed once, the characters and the like in this portion are changed, for example, A → B → C ... X → Y → Z → 0 → 1 → 2.

6) The mode is shifted to the STOP mode, and the set is ready for normal use.

FIG. 8 is a flowchart showing a user ID code setting processing operation in the audio recording / reproducing apparatus of this embodiment. It should be noted that, in the figure, a flowchart schematically shown on the left half side represents a process of reading out a user ID code from the recording medium 7 and selecting from among them.
The flowchart shown on the right half side shows a process in which a user sets an arbitrary user ID code by operating the ID code setting operation unit 13.

As described above, when the user keeps pressing the third operation button (MENU) 13c (MENU button) for 2 seconds or more, the process enters the ID code setting process shown in this flowchart.

First, the main controller 6 checks whether a memory card (recording medium 7) is mounted (step S).
11) If not mounted, ID code setting operation unit 1
The process proceeds to the process set in step 3, and if it is mounted, the process proceeds to the next step.

Next, the main control section 6 detects whether or not there is recorded audio data in the recording medium 7 (step S1).
2) If the voice data exists, the process proceeds to the next process. If the voice data does not exist, the ID code setting operation unit 1
The process proceeds to step 3 for setting an ID code.

When a memory card containing voice data is inserted, the main control unit 6 accesses the index information area of each voice data and extracts an ID code (step S13). When a plurality of types of ID codes are detected, the main control unit 6 sets the total number of types to N (step S14), for example, sorts in ascending order (step S15), and sets the display order n to 1 (step S1).
6) Display the first ID code (step S1)

9), Step S for displaying the current n-th ID code
Returning to step 17, if pressed, the operation of n = n + 1 is performed (step S20).

Here, unless n> N (step S2
1) Returning to step S17 for displaying the n-th ID code, the next ID code is displayed because the number of n is increased by one (step S22). Here, the second
When the operation button (SEL) 13b is pressed and the operation of n = n + 1 is performed, and n> N, it means that all ID code candidates have been displayed, and the ID code setting operation unit 13 To shift to the process of setting the user ID code.

The user ID is set in the ID code setting operation section 13
When the process proceeds to the code setting process, the currently set user ID code is displayed (step S2).
2), the value of the blinking digit number B is set to 4 (step S2).
3) The character (alphanumeric) of the digit corresponding to the value of B (in this case, the most significant digit of the 4-digit code) is blinked (step S24), and this digit is to be changed. Show that.

If the ID code currently displayed is acceptable, the user presses the third operation button (MENU) 13c (step S25). Thereby, the main control unit 6
The displayed ID code is recorded on the recording medium 7 as a new user ID code (step S31), and the user ID code setting process ends.

In step S25, the third operation button (M
If (ENU) 13c is not pressed, the process moves to the next step. Here, when the second operation button (SEL) 13b is pressed (step S26), an operation of subtracting 1 from the blinking digit number B is performed (step S29). If B = 0 is not satisfied (step S30), the ID code of the ID code is deleted. Returning to the blinking display, since the value of B has decreased by one, the character of the next digit blinks.

When the second operation button (SEL) 13b is 4
When B = 0 (step S30), it is determined that the user has confirmed all four digits, and the main control unit 6
Replaces the currently displayed ID code with the new user ID.
It is recorded on the recording medium 7 as a D code (step S3).
1), the user ID code setting process ends.

In steps S25 and S26, the third operation button (MENU) 13c and the second operation button (S
EL) 13b, and the first operation button (SET) 13a is pressed (step S2).
7) The characters that are currently flashing are displayed in ascending order, for example, A → B,
The character is changed to the next character, such as G → H, S → T (step S28), and the ID code is displayed in a partially blinking step S.
Return to 24.

Thus, the first operation button (SET)
A user ID code setting operation is performed by operating the first operation button 13a, the second operation button (SEL) 13b, and the third operation button (MENU) 13c.

As described above, in this embodiment, in addition to the method of operating the ID code setting operation section 13 to set the user ID code, the user ID code recorded in advance on the recording medium 7 is read and displayed. The displayed user ID code can be set as a new user ID code. Therefore, once the user ID code is set and recorded, the recording of the user ID code of the recorder remains on the recording medium, and the user ID code of the recorder is set in the system reset or another device. Even if the user wants to do so, the user ID code can be set only by mounting a recording medium on which the user ID code is recorded and performing a very simple operation.

In this embodiment, a DSP is used as the digital signal processing unit 5, a CPU is used as the main control unit 6, a memory card such as a flash memory is used as the recording medium 7,
The display unit 12 is assumed to be an LCD, but may be replaced by one having the same function.

For example, the digital signal processing section 5 can be a CPU with a remarkably high processing speed, and can also serve as a DSP.

The recording medium 7 may be a non-volatile recording medium, such as a magnetic tape device, a magnetic disk device, or a magneto-optical disk device.

Further, the display section 12 may be a multi-segment LED display.

Further, in this embodiment, a dry battery is assumed as the main power source and a lithium battery is assumed as the auxiliary power source. However, a nickel cadmium battery, a nickel hydride battery, or an AC adapter is used as the main power source. Is also good.

As described above, according to the audio recording / reproducing apparatus of the present embodiment, the user can set an arbitrary character (alphanumeric character) one character at a time for setting the user ID code as in the related art.
In addition to the setting method of setting the user ID from the recording medium on which audio data with index information has already been recorded
A code is read out and displayed, and when there are a plurality of codes, it is possible to select one of them and set it as a new user ID code.

As a result, even when the voice recording / reproducing apparatus used by the user is reset due to running out of batteries including a spare battery or an unexpected malfunction, the work of resetting the user ID code is significantly simplified. It works.

Similarly, the ID code can be set by a simple procedure when the user replaces the audio recording / reproducing apparatus or purchases an additional audio recording / reproducing apparatus.

Further, even when a single audio recording / reproducing apparatus is used by a plurality of persons, the user ID code can be easily changed by mounting a recording medium on which each person has recorded.

The audio recording / reproducing apparatus according to the present embodiment having the above-described effects is particularly suitable for recording by a small number of typists or transcribists by a large number of persons, and performing documenting by type or word processor. It will be very useful in the field of dictation / transcription.

Even when the voice recording / reproducing apparatus is reset, the ID code is automatically set by default at the time of default, so that the user is limited to an individual and can simply record and reproduce voice.
