Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data which can be recorded / reproduced by associating continuous data recorded continuously in time series with handwritten data such as characters and figures inputted from an input surface by means of coordinate input means. The present invention relates to a recording / reproducing device.

[0002]

2. Description of the Related Art With the spread of personal computers in recent years, various information devices excellent in man-machine interface have been proposed. As one of them, what is called a so-called audio electronic notebook, which is used for recording a meeting or a presentation, has been proposed.

[0003] The audio electronic organizer is for recording voices and images continuously in chronological order, detecting the trajectories of characters and figures input to the tablet with a pen as appropriate, and recording them as a memo. . The recorded continuous data such as voices and the written data such as memos are stored in a memory inside the voice electronic organizer in a time-related manner. When the user designates a portion of the tablet where the writing data is recorded with a pen, the coordinates of the portion are detected, the writing data is specified, and the continuous data of the portion corresponding to the writing data is read from the memory. Then, the sound of the portion corresponding to the writing data specified by the pen is reproduced from the speaker of the sound electronic organizer.

[0004]

However, in the conventional voice electronic notebook, the user controls the recording / reproducing operation of continuous data such as voice while the user designates the portion of the tablet where the handwritten data is recorded by using a pen. There was a problem that can not be. This is because, in the conventional audio electronic notebook, an instruction for a continuous data recording / reproducing operation cannot be issued from the tablet, but is performed by operating a switch or the like provided separately from the tablet.

[0005] Therefore, when the user needs to fast-forward or rewind in order to search for the continuous data of the necessary portion, the pen indicates the portion of the tablet where the writing data has been recorded with a pen to output voice or the like. Playback, then fast-forwarding and rewinding by operating a switch and the like, and furthermore, the operation of pointing the tablet with a pen must be repeated, and the operation is very complicated.

If it is necessary to input a handwriting with a pen during the reproduction of continuous data such as voice, it is necessary to switch a voice reproducing mode to a handwriting input mode by operating a switch or the like, and the handwriting input ends. In such a case, the operation becomes very complicated, for example, it is necessary to switch to the audio reproduction mode.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a recording and reproducing operation of continuous data such as voice is performed while a user designates a portion of a tablet where writing data is recorded with a pen. It is an object to provide a data recording / reproducing device which can be controlled.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

First, an overall configuration of a voice electronic notebook 1 as a data recording / reproducing apparatus according to the present invention will be described with reference to FIG. FIG. 1 is a plan view showing the external appearance of the voice electronic organizer 1.

As shown in FIG. 1, a plurality of sheets of paper 3 closed by six rings 5 are stacked in the center of the voice electronic organizer 1. This paper 3
Can turn pages like a normal system organizer.

The voice electronic organizer 1 is provided with a tablet 17 (see FIG. 2) as an input surface for detecting coordinate data by magnetic coupling with a pen 16 (see FIG. 17 and the like) as coordinate input means. The tablet 17 is arranged below the paper 3, and characters are written only on the paper 3 on the right side.

On one side of the audio electronic organizer 1, there are provided buttons 7 corresponding to a plurality of functions such as recording and reproduction of audio. Above the button 7, a microphone 11 for collecting and recording voice is provided, and below the button 7,
A speaker 13 for reproducing the recorded voice is provided. A liquid crystal display (hereinafter, referred to as an LCD) 15 for displaying the current page number, a predetermined message, and the like is provided above the audio electronic organizer 1.

A page turning sensor 9 for detecting that the sheet 3 has been turned is provided at the upper center of the voice electronic notebook 1 and at the upper end of the plurality of rings 5.
Specifically, the page turning sensor 9 is a photo interrupter that detects light reflection, and detects light reflected from the sheet 3 when the sheet 3 is turned, and uses the light as a page turning signal. What to send.

The pen 16 (see FIG. 17) used for the voice electronic organizer 1 forms characters on the paper 3 by oozing ink from its tip. Pen 16
Generates an AC magnetic field from the same tip, and when the tip is brought into contact with the surface of the tablet 17, the tablet 17 detects the coordinates of the tip of the pen 16 by this magnetic field. Pen 16
Is disclosed in Japanese Patent Application No. 11-2235 by the inventor of the present application.
Since the structure of the pen used in the electronic blackboard described in No. 30 is substantially the same as that of the pen described above, the description thereof is omitted here.

When the user operates the buttons 7 arranged on the right side of the audio electronic notebook 1 to set the audio electronic notebook 1 in the “recording mode”, the sound collected by the microphone 11 is transmitted to the audio electronic notebook 1.
It is recorded continuously. At the same time, the user takes notes as necessary while listening to the sound. That is, memos such as characters and figures are written and input on the tablet 17 via the paper 3 by the pen 16.

In this manner, the audio data continuously input in a time series is associated in a time series with the writing data such as characters and figures and the page data (described later) of the sheet to which the writing data is input. Then, the data is stored in the memory 45 (see FIG. 2) as the input data storage means of the voice electronic notebook 1.

Similarly, when the user operates the button 7 to set the voice electronic notebook 1 to the "play mode" and designates an arbitrary character on the paper 3 with the pen 16, the character is recorded in the memory at the time when the character was written. The generated voice is emitted from the speaker 13 as voice data stored in association with the writing data.

Therefore, the voice electronic organizer 1 can record and reproduce voice data and handwritten data such as characters and figures inputted from the tablet 17 with the pen 16 so that a memo can be taken at a meeting or a presentation. This is a very useful device to listen to while talking and check the contents later.

Further, the paper 16 is passed through the paper 3 by the pen 16.
When inputting writing data such as characters and figures on the tablet 17, when the paper 3 is full of characters or figures or the page is broken for convenience, the user has finished writing. Turn over paper 3 and write on new paper 3. Then, it is necessary to distinguish which page of the input handwritten data is handwritten and input on the sheet 3. When writing data is input to a single tablet 17 via a plurality of pages of paper 3, if the input data is input again at the same location,
Whether it was written on a different page of paper 3
This is because the apparatus cannot recognize whether the input has been made by handwriting over the sheet 3 of the same page.

Therefore, in the paper 3 used in the audio electronic organizer 1, the paper 3 to which the writing data is to be input at a predetermined position of the paper 3 is a paper 3 of a plurality of pages of paper 3. A page registration area for registering the page data indicating “.” Is formed.

This page registration area is specifically configured as a plurality of marking sections 30 printed on the surface of the paper 3. Then, by writing the marking by at least one of the plurality of marking fields 30 with the pen 16, the page data of each sheet 3 to which the writing data is input can be registered. I have. That is, since the tablet 17 of the audio electronic notebook 1 can detect the coordinates input by the pen 16, it is possible to identify which marking field 30 the writing is input by the pen, and the input result is displayed on a sheet. Can be registered as page data.

It should be noted that ordinary handwritten data such as characters and symbols cannot be entered in the marking section 30.
This is because, even if normal writing data is input to this area, the page is recognized as input by the device.

When reproducing voice data stored in association with writing data input over a plurality of pages, first, a mark is placed on the tablet 17 in the marking field 30 where the marking has already been written. Pen 1
6 is used to input the marking again. By detecting the coordinates of the handwritten input marking on the tablet 17, the page data of the paper 3 on which the handwritten data is handwritten is specified. Next, a predetermined portion of the sheet 3, for example, a portion where a specific character or symbol is written is indicated by the pen 16. Thereby, the writing data corresponding to the predetermined portion of the writing data written on the sheet 3 of the page is specified. That is, the writing data having the coordinates closest to the coordinates indicated by the pen 16 is specified.
Then, the audio data stored in association with the page data and the handwritten data specified in this way is read out from the memory 45 and reproduced.

Therefore, it is possible to efficiently retrieve and reproduce only necessary voice data from among voice data continuously recorded for a long time, using handwritten data written on a plurality of pages of paper 3 as a clue. it can.

Next, the electrical configuration of the audio electronic organizer 1 will be described with reference to FIGS. FIG. 2 is a block diagram showing an electrical configuration of the voice electronic organizer 1, and FIG.

As shown in FIG. 2A, the sound electronic notebook 1 includes the page turning sensor 9, the microphone 11,
In addition to the speaker 13, the LCD 15, and the tablet 17, an amplifier circuit 41 that collects sound from the microphone 11 and amplifies the sound converted into an electric signal, encodes the amplified sound signal, and decodes the encoded sound signal. Codec 4 that performs

An amplification circuit 55 for amplifying the induction signal detected by the tablet 17, a detection circuit 57 for extracting a signal effective for coordinate detection from the induction signal, and an A / D converter for converting the detected signal into a digital signal 59 is a main part. Note that the button 7 is configured as a part of the grid 51, and determines that “the button 7 has been pressed” when the AC magnetic field generated by the pen 16 is detected at coordinates corresponding to the position of the button 7. It has been like that.

As shown in FIG. 3, the grid 51 formed on the tablet 17 is repeatedly scanned by the selector 53 with respect to the sense coils X1 to X21 and the sense coils Y1 to Y29 to detect the induction signal, and thereby the pen 11 is detected. Is to detect the coordinates specified by. Grid 5
1 has a sense coil X1 arranged in the left-right direction in FIG.
To X21 and sense coils Y1 to Y arranged in parallel in the vertical direction.
29 are arranged orthogonally. Note that the sense coil X
1 to X21 are arranged so that each overlaps with the adjacent sense coil. The sense coils Y1 to Y29 are also
Similarly, they are arranged so as to overlap with adjacent sense coils.

When the sense coils X1 to X21 and the sense coils Y1 to Y29 are scanned, the tablet 1
The induction signal generated by the magnetic coupling between the AC magnetic field generated from the pen 16 abutting on the sensor 7 and the sense coils X1 to X21 and the sense coils Y1 to Y29 is amplified by the amplifier circuit 55, and the amplified signal is The amplitude detection is performed by the detection circuit 57. At this time, a signal indicating a voltage value corresponding to the amplitude value is output from the detection circuit 57, and the signal output from the detection circuit 57 is output to the A / D converter 5.
9, the digital value corresponding to the voltage value (hereinafter, “R

Here, by such scanning, the detection value (R) obtained from the sense coil Xn via the detection circuit is obtained.
The relationship between SSI) and the position of the coil will be described with reference to FIGS. FIG. 4B illustrates a case where the CPU 16 is in a case where the pen 16 is vertically contacted with the tablet 17 (that is, when the inclination angle α of the pen 16 illustrated in FIG. 4A is 0 degree). By scanning the sense coil Xn, each sense coil X obtained from the detection circuit is scanned.
7 is a graph showing a detection value from n. FIG. 5 (b)
When the pen 16 is in contact with the tablet 17 at an angle of 20 degrees with respect to the normal line of the tablet 17 (that is, when the inclination angle α of the pen 16 shown in FIG.
17 is a graph showing a detection value from each sense coil Xn acquired from the detection circuit by scanning the sense coil Xn. 4 (b) and FIG. 5 (b) indicate the position of each sense coil Xn, and the value indicated on the vertical axis indicates the value detected from each sense coil Xn laid at that position ( RSSI).

Then, such a signal is transmitted to the A / D converter 5
9 to the CPU 47 side, the CPU 47 associates the detected value (RSSI) from each of the sense coils Xn acquired during scanning of the sense coils X1 to X21 with the memory 45 in association with the coil number of each of the sense coils Xn. When a detection value (RSSI) exceeding a predetermined value is obtained from the detection circuit and the pen 16 is brought into contact with the touch panel, a coordinate reading process described later is executed, and The contact position of the pen 16 is read.

Next, a coordinate reading process for reading the contact position of the pen 16 when the pen 16 is in contact with the tablet 17 of the audio electronic notebook 1 will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a flowchart showing the contents of the coordinate reading process. FIG. 7 shows the contact position of the pen 16 and the coils Cp, C1-, C1 + and the coils Cn1-, Cn1 +.
6 is a graph showing a relationship with a detection value (RSSI) from the data.

When the processing is executed, first, the CPU 47
In S110, the coil Cp whose RSSI indicates the maximum value Vp is determined from the above-described data in which the RSSI of each sense coil Xn stored in the memory 45 is associated with the coil number. Then, the CPU 47 determines in step S120 that the two coils C1 located on both sides of the determined coil Cp
The detected values (RSSI) V1- and V1 + of-and C1 + are read from the memory 45, and it is determined whether or not the detected values indicate the same value. At this time, as shown in FIG. 7, the detected values (RSSI) of the coils C1- and C1 + substantially coincide with each other at the contact position of the pen 16 where the detected value of the coil Cp indicates the maximum value.

The pen 16 is brought into contact with such a position, and the RSSIs of the coils C1- and C1 + have the same value (V
If c) is indicated (YES in S120), CPU 47
In S130, from the above data, two coils Cn1 located at positions separated by a predetermined number N1 on both sides of coil Cp.
−, Cn1 + detection values (RSSI) Vn1-, Vn1 +
Is obtained, and further, the detection values of the coils C1- and C1 + (RS
SI) Vc and the detected value (RSSI) Vn1-, Vn1 + of each coil Cn1-, Cn1 + located at a position separated from the coil Cp by a predetermined number N1 on both sides, and the angle representing the inclination angle using the equation (1). Calculate the parameter Q1.

Q1 = (Vc−Vn1 −) / (Vc−Vn1 +) (1) When the parameter Q1 is calculated in this manner, C
In step S140, the PU 47 calculates the tilt correction coefficient F using Expression (2), and temporarily stores the calculated tilt correction coefficient F in the memory 45.

[0040]

(Equation 1)

It should be noted that the tilt correction coefficient F [i] is a coordinate correction value D (which is expressed by the following equation (5)) representing the distance from the position of the center line of the coil Cp where the maximum value Vp is generated to the contact position of the pen 16. )) Is calculated from the N3 degree polynomial of the distance parameter Q2 to be described later, to the power Q2 ⁱ (0
≦ i ≦ N3: integer).

A [i, k] is experimentally obtained from the relationship between the tilt angle of the pen 16 and a coordinate reading error caused by the tilt angle of the pen 16, which is previously measured by the audio electronic notebook 1 having the same configuration. It is a predetermined constant derived,
This is stored in the ROM of U47.

That is, in this embodiment, the parameter Q
In order to obtain a coordinate correction value D (described later) while calculating a tilt correction coefficient F from 1 and correcting a coordinate reading error caused by the inclination angle of the pen 16, the pen 1 An experimental value (Dexp) corresponding to the coordinate correction value D is fitted with a function of the parameters Q1 and Q2 from the experimental data in which the detected values from the coils obtained by changing the inclination angle of 16 are changed, and a [i, k] is calculated and stored in the ROM of the CPU 47.

Thereafter, in S160, the CPU 47
From the tilt correction coefficient F calculated at 140 and Q2 calculated at S150, the coordinate correction value D is calculated using Expression (3).
Is calculated.

[0045]

(Equation 2)

In the following S170, the CPU 47
Calculates the coordinate X at which the pen 16 is in contact with the coordinate correction value D calculated in S160. That is, CPU
47 reads out the coordinate value of the center line of the coil Cp that generated the maximum voltage from the coordinate data of each coil stored in the ROM in advance, and reads the coordinate value of the pen 16 from the center line of the coil Cp.
Is added to the coordinate correction value D representing the distance to the contact position of
The coordinates of the contact position of the pen 16 are calculated. Also, after this,
The CPU 47 stores the calculated coordinates in the memory 45,
The coordinate reading process ends.

If the detected values V1- and V1 + of the coils C1- and C1 + on both sides of the coil Cp do not match in S120 (NO in S120), the CPU 47
In S125, the tilt correction coefficient F calculated in the coordinate reading process is read from the memory 45, and based on this,
The process between 50 and S170 is performed according to the above-described procedure, and the X coordinate is calculated.

In the above, the procedure for obtaining the X coordinate using the detected value (RSSI) of the sense coil Xn (S110)
To S170), but in the present embodiment, the contact position of the pen 16 on the tablet 17 is two-dimensional (X,
Y) In order to read the coordinates, the same procedure (S110 to S170) as the procedure for obtaining the X coordinate from the detected value of the sense coil Xn and the procedure for obtaining the X coordinate using the detected value of the sense coil Yn is performed in the above-described procedure. To determine the Y coordinate.

Next, an angle detection process for detecting the angle of the pen 16 when the pen 16 is in contact with the tablet 17 of the audio electronic organizer 1 will be described with reference to FIGS. FIG. 8 is a flowchart showing the contents of the angle detection processing, and FIG. 9 is a graph showing the relationship between the contact position of the pen 16 and the signal detected from the coil.

In the angle detection processing, the inclination angle of the pen 16 is calculated from the angle parameter Q1 obtained in the coordinate reading processing. That is, in the coordinate reading process, the tilt correction coefficient F is calculated from the angle parameter Q1, and the formula for calculating the coordinate correction value D is changed using the tilt correction coefficient F (that is, the coefficient related to Q2 is changed). The coordinate correction value D is calculated so as to remove the coordinate error due to the tilt angle of the pen 16. However, if the relationship between the tilt angle and the angle parameter Q1 is previously determined by an experiment, the tilt angle is calculated from the relationship and the parameter Q1. Can be calculated.

Specifically, the contact position of the pen 16 and the tilt angle of the pen 16 are changed in advance within a range where one certain sense coil X shows the maximum voltage, and the tilt angle α of the pen 16 is The detected values V1- and V1 + of the coils C1- and C1 + on both sides of the coil Cp are the same value (V1- = V1 + = Vc)
, Each of the coils Cn1-, C located at positions separated by a predetermined number N1 on both sides of the detection value Vc and the coil Cp.
The n1 + detection values (RSSI) Vn1- and Vn1 + are measured.

Then, the parameter Q1 calculated from these measurement data and the inclination angle α of the pen 16 are fitted by a function represented by the equation (4) to obtain b [k].
And b [k] is stored in the ROM of the CPU 47 or the like.

[0053]

(Equation 3)

Then, the CPU 47 of the voice electronic organizer 1 executes an angle detection process shown in FIG. 8 to detect an inclination angle. When this processing is executed, first, the CPU 47
In S210, the coil Cp whose RSSI indicates the maximum value Vp is determined from the data of the detected values of the sense coils obtained by scanning, and in S220, the detected values of the coils C1- and C1 + on both sides of the coil Cp are determined. It is determined whether they indicate the same value (Vc).

The coil C1 on both sides of the coil Cp
If the detected values of − and C1 + indicate the same value (Vc) (S22
(YES at 0), the CPU 47 shifts the processing to S230, and detects the detected values (RSSI) Vc of the adjacent coils and the coils Cn located at positions separated by a predetermined number N1 on both sides from the coil Cp.
1-, Cn1 + detection value (RSSI) Vn1-, Vn1
From +, the angle parameter Q1 is calculated using equation (1). On the other hand, the coils C1- and C1 + on both sides of the coil Cp
Are not the same (NO in S220),
Similarly, the parameter Q1 is calculated (S231). However,
As shown in FIG. 9, Vn1 +
Vpb1 to Vpb2, Vn1-Vpb2 to Vpb1
, There is an error in the value of Q1 compared to the case where the detected values of the coils C1- and C1 + on both sides of the coil Cp are the same. However, the approximate inclination angle (S241) calculated based on this can be sufficiently used for performing sound reproduction control described later. That is, it can be sufficiently used to determine whether or not the inclination is about 30 ° or more from the reference state.

Subsequently, in S240, the CPU 47 calculates the inclination angle α of the pen 16 from equation (4) using the parameter Q1 and b [k] stored in the ROM.
The calculated inclination angle α is stored in the memory 45. In this way, the pen 1
6 are detected.

Next, the processing to be executed by the CPU 47 at the time of handwriting input in the voice electronic notebook 1 is described.
The processing executed by the CPU 47 at the time of audio reproduction in will be described with reference to FIGS. FIG.
FIG. 11 is a flowchart showing processing in the writing mode of the audio electronic notebook 1, and FIG. 11 is a flowchart showing processing in the reproduction mode of the audio electronic notebook 1.
2 is a flowchart showing a rewind playback process in the playback mode. FIG. 13 is a flowchart showing a fast-forward playback process in the playback mode. FIG. 14 is a flowchart showing a pause process in the playback mode. 14 is a flowchart showing slow playback processing in a playback mode.

First, processing in the writing mode of the audio electronic notebook 1 will be described. As shown in FIG. 10, when this process is first activated, first in S310, the pen 16
Attempts to detect strokes to determine whether or not they have been written. This is performed by the selector 53 scanning the sense coils X and Y and detecting the induced current due to the AC magnetic field generated by the pen 16. If a stroke by the pen 16 is detected in S310, the process advances to S320 to detect whether or not page data has been input by the page registration process of the pen 16, ie, whether or not a handwriting input to the page registration area 30 has been performed. Is determined. On the other hand, in S310, the pen 1
If it is not determined that the handwriting input by the user 6 has been performed, the process proceeds to S380, where a warning sound is generated from the speaker 13 and a predetermined page check request message is displayed on the LCD 15.

If it is determined in S320 that page data has been input with the pen 16, the flow advances to S330 to determine whether or not the page data is already registered page data. On the other hand, in S320, the pen 16
If it is not determined that the page data has been input, the process proceeds to S370, where the stroke data by the pen 16 is stored in the input buffer, and then the process proceeds to S380.
A warning sound is generated from the speaker 13 and the LCD 1
5, a predetermined page check request message is displayed.

If it is determined in S330 that the page data is not already registered page data,
If it is new page data and the process proceeds to S340, and the writing data by the pen 16 is already stored in the input buffer, the stroke data is stored in the memory 45 as a stroke of the new page. And S350
And the user performs a handwriting input process.

Next, in S360, it is detected by the page turning sensor 9 whether the sheet 3 has been turned. The writing process is continued while the paper 3 is not turned. And
When the paper 3 is turned over, a page check request is issued (S380), and it is determined whether or not page data has been input to the page registration area 30 for the paper 3 on the tablet 17 to be newly written and input (S320). ). If it is not determined that the page data has been input for the new sheet 3, a warning sound is generated from the speaker 13 and a predetermined page check request message is displayed on the LCD 15 (S380).

On the other hand, if it is determined in S330 that the page data is already registered page data, there is a possibility that the same page data has been added to a plurality of pages. A warning sound is generated from the LCD 13 and a message is displayed on the LCD 15 for confirming whether or not additional writing to an existing page is going to be performed. If the user intends to open a page that has already been registered and follow up the checks written in the page registration area 30 to add data, press the fast forward or rewind button 7,
Enter that it is postscript. When there is no intention to input a new page, the stop button 7 is pressed.

Then, the process proceeds to S400, in which it is determined whether or not additional writing is to be performed on an existing page. If it is determined that additional writing is to be performed, the process proceeds to S340, where additional writing is performed by the pen 16 before page determination. If the handwritten data is in the input buffer, the handwritten data is stored in the memory 45. On the other hand, if it is not determined in S400 that it is additional writing, the process proceeds to S410, where a message for requesting input of page data of new paper 3 is displayed on LCD15. At this time, a check is further added to the page registration area 30 and registered as a new page. In this way, the processing in the writing mode of the audio electronic notebook 1 is performed.

Next, processing in the playback mode of the audio electronic organizer 1 will be described. As shown in FIG. 11, when this process is started, first, in S510, it is detected whether or not the pen 16 is in contact with the tablet 17. If the pen 16 is not in contact with the tablet 17, the process waits until the pen 16 is in contact. Then, when the pen 16 is brought into contact with the tablet 17, the process proceeds to S520, and the pen 1
It is determined whether or not there is a stroke, that is, writing data within a predetermined range from the position on the tablet 17 with which the tablet 6 contacts. This is because voice data cannot be reproduced at a position where there is no handwritten data because voice data is associated with handwritten data. Therefore, in S520, the pen 1
If it is not determined that there is a stroke within the predetermined range on the tablet 17 specified by 6, the process waits until the stroke comes into contact with the position where the stroke exists. And S5
If it is determined in step S20 that there is a stroke within a predetermined range on the tablet 17 with which the pen 16 has contacted,
Proceeding to 30, the inclination angle of the pen 16 with respect to the tablet 17 is acquired. The detection of the inclination angle of the pen 16 is performed by the above-described angle detection processing. The pen 16 obtained here
Is stored in the memory 45 of the voice electronic organizer 1 as a reference state of the pen 16. Note that a difference in the angle within a predetermined range from the reference state is considered to be in the reference state. When the tilt angle of the pen 16 is obtained in this manner, the process proceeds to S540, in which the audio data stored in the memory 45 is read out in association with the writing data such as characters and figures designated by the pen 16 via the tablet 17. , Start playing the audio.

In the present embodiment, the predetermined reference state of the pen 16 is a state when the pen 16 instructs the tablet 17 to reproduce sound data stored in association with writing data such as characters and figures from the tablet 17. However, the reference state may be a state in which the pen 16 inputs writing data such as characters and figures from the tablet 17. Alternatively, the state when the reproduction button 7 is pressed with the pen 16 may be used.

Then, in a state in which the sound is being reproduced, it is determined in S550 whether or not the pen 16 has instructed writing data such as characters or figures in the current field of the tablet 17 or a position different from that of the tablet 17. When the instruction by the pen 16 is not performed, the sound reproduction is continued until the instruction is performed. If it is determined in S550 that the pen 16 has instructed writing data such as characters and graphics on the tablet 17, the process proceeds to S560, and the character is set within a predetermined range from the position indicated by the pen 16 on the tablet 17. It is determined whether or not there is writing data such as a character or a graphic.
In S560, when it is determined that the writing data exists within the predetermined range, the process proceeds to S570, and the inclination angle of the pen 16 with respect to the tablet 17 is detected. Note that S560
If it is not determined that the handwritten data exists within the predetermined range, the process proceeds to S640, and the reproduction of the sound is stopped.

When the tilt angle of the pen 16 with respect to the tablet 17 is detected in S570, the process proceeds to S580, and it is determined whether the tilt angle of the pen 16 is in the previously acquired reference state. If it is determined in step S580 that the pen 16 is in the reference state, the process advances to step S650 to read out the voice data stored in association with the writing data such as the character or graphic designated by the pen 16, and read out the voice data. Play at normal speed. Then, the reproduction of the sound is continued until writing data such as a character or a graphic at a different position on the tablet 17 is designated by the pen 16 or until the inclination angle of the pen 16 changes.

If it is not determined in step S580 that the pen 16 is in the reference state, the reproduction operation control of the audio data is performed based on the tilt angle information of the pen 16 detected by the above angle detection processing. Is performed.

Specifically, if it is not determined in step S580 that the pen 16 is in the reference state, the process proceeds to step S590, where the pen 16 is moved leftward from the reference state with respect to the tablet 17. It is determined whether or not the tilt angle is equal to or more than a predetermined angle (for example, 30 °) predetermined in advance. S
If it is determined at 590 that the pen 16 is inclined leftward from the reference state by a predetermined angle or more, the process proceeds to the rewind reproduction process shown in FIG. In the rewind reproduction process, in S700, the audio data stored in the memory 45 in association with the writing data such as the character or graphic designated by the pen 16 goes back to the past at a predetermined interval in a direction opposite to the normal direction. Will be played. And S7
Proceeding to 10, the inclination angle of the pen 16 with respect to the tablet 17 is detected. Further, the process proceeds to S720, in which it is determined whether or not the tilt angle of the pen 16 detected in S710 is in the above-described reference state or in a state in which the pen 16 is tilted to the right. In S720, when it is determined that the tilt angle of the pen 16 is tilted leftward from the above-described reference state, the rewind reproduction is continued. That is, while it is detected that the pen 16 is inclined to the left by a predetermined angle or more from the reference state, the rewind reproduction is continuously performed. Then, in S720, when it is determined that the tilt angle of the pen 16 is not tilted to the left from the above-described reference state, the rewind playback is stopped, the normal voice playback is performed, and the pen It is detected whether or not there is a new instruction by S.16 (S550).

If it is not determined in step S590 that the pen 16 is inclined leftward from the reference state by a predetermined angle or more, the process proceeds to step S600.
With respect to the tablet 17, the pen 16 is moved from the above-described reference state by a predetermined angle (for example, 30
Ii) It is determined whether or not the inclination is above. In S600, when it is determined that the pen 16 is inclined to the right from the reference state by a predetermined angle or more, FIG.
The process proceeds to the fast-forward playback process shown in FIG. In this fast-forward playback process, in S800, the audio data stored in the memory 45 in association with the writing data such as the character or figure designated by the pen 16 is played back at a predetermined interval while being fast-forwarded. Then, the process proceeds to S810, where the inclination angle of the pen 16 with respect to the tablet 17 is detected. Further, S8
Proceeding to 20, it is determined whether or not the tilt angle of the pen 16 detected in S810 is a state in which the pen 16 is tilted rightward from the reference state. In S820, if it is determined that the tilt angle of the pen 16 is tilted rightward from the above-described reference state, fast-forward playback is continued. That is, while it is detected that the pen 16 is inclined to the right by a predetermined angle or more from the reference state, the fast-forward reproduction is continuously performed. Then, in S820, when it is determined that the tilt angle of the pen 16 is not tilted rightward from the above-described reference state, the fast-forward playback is stopped, normal voice playback is performed, and the pen 16 Is detected (S550).

If it is not determined in step S600 that the pen 16 is inclined to the right from the reference state by a predetermined angle or more, the process proceeds to step S610.
It is determined whether or not the pen 16 is tilted by a predetermined angle (for example, 30 °) in the upward (backward) direction with respect to the tablet 17 from the above reference state. S
If it is determined in 610 that the pen 16 is inclined at a predetermined angle or more in the upward (rear) direction from the reference state, the process proceeds to the pause processing shown in FIG. In this pause process, in S900, the sound reproduction is temporarily stopped, and the pen 16 enters a state in which writing data such as characters and symbols can be input to the tablet 17 with the pen 16. That is, the pen 1
6 indicates a predetermined position on the tablet 17, the sound data stored in the memory 45 in association with the writing data corresponding to the position is not reproduced, but the pen 1.
6 is input as handwritten data based on the coordinates designated by the user. With this, based on the reproduced sound,
A complete note can be obtained by performing additional writing with the pen 16 on the portion where the note has been missed. The process proceeds to S910 while the input processing of the writing data is performed in this way, and the inclination angle of the pen 16 with respect to the tablet 17 is detected. Then, the process proceeds to S920, and it is determined whether or not the pen 16 has tilted upward (backward) again from the reference state and returned to the reference state. In S920, if it is not determined that the pen 16 has tilted up (backward) again and returned to the reference state, the input of the writing data is continued. On the other hand, S920
If it is determined that the pen 16 has tilted upward (backward) again, the process proceeds to step S930, where the input of writing data is stopped, and normal voice reproduction is performed. And pen 1
6 is detected (S55).
0).

If it is not determined in step S610 that the pen 16 is inclined at a predetermined angle or more in the upward (rear) direction from the reference state, the process proceeds to step S620 and the tablet 17 On the other hand, it is determined whether or not the pen 16 is inclined by a predetermined angle (for example, 30 °) or more in a downward (forward) direction from the reference state. If it is determined in S620 that the pen 16 is inclined downward (forward) from the reference state by a predetermined angle or more, the process proceeds to the slow reproduction process shown in FIG. In this slow reproduction process, in S1010, the sound is reproduced in slow motion, and writing data such as characters and symbols can be input to the tablet 17 by the pen 16. That is, the tablet 17 is
Even if the user designates the above predetermined position, the sound data stored in the memory 45 in association with the writing data corresponding to the position is not reproduced, but is input as the writing data based on the coordinates indicated by the pen 16. Because Thus, while listening to the sound that is being played back in slow motion, the portion where the memo has been missed can be additionally recorded with the pen 16 to obtain a complete memo. The process proceeds to S1020 while the input processing of the writing data is performed in this manner, and the inclination angle of the pen 16 with respect to the tablet 17 is detected. Then, the process proceeds to S1030, where it is determined whether or not the pen 16 has tilted downward (forward) again from the reference state and returned to the reference state. In S1030, if it is not determined that the pen 16 has tilted down again (toward the front) and has returned to the reference state, the input of the writing data is continued. On the other hand, S103
At 0, if it is determined that the pen 16 has tilted down again (toward the front) and has returned to the reference state, the process proceeds to S1040, where input of writing data is stopped, and normal voice reproduction is performed. Then, the process proceeds to detection of whether or not there is a new instruction by the pen 16 (S550).

FIG. 27 is an explanatory diagram showing an operation state of the audio electronic notebook 1 during slow reproduction, and FIG. 27 is an explanatory diagram showing an operation state of switching the audio electronic notebook 1 from slow reproduction to normal reproduction.

In the present embodiment, a case will be described as an example where the audio electronic organizer 1 is used for recording and memo in a presentation on a new PC (personal computer).

First, an operation state of the audio electronic notebook 1 in the writing mode will be described. For example, in a presentation, "I developed a new PC. The CPU is XXXXXX, the clock is 700 MHz, the memory is 128 MB. The DVD-ROM drive and floppy (registered trademark) drive are built-in. The pointing device is a touchpad, the display is a 15-inch TFT, and the resolution is UXGA. "

At this time, the sound of this explanation is collected by the microphone 11 provided in the sound electronic notebook 1, and is continuously stored in the memory 45 as sound data. At the same time, as shown in FIG.
The marking 31 is written in the marking box 30 at the right end of the page with the pen 16, and the "new PC"
Key words such as "CPU xxxxxx", "memory", "pointing", "display is 15", and "resolution" are input by hand. In this way, the voice data and the handwritten data such as characters and figures are recorded in association with each other.

Next, an operation state of the audio electronic organizer 1 in the reproduction mode will be described. When the reproduction of the sound is started, as shown in FIG. 17, a specific written data, for example, a portion where the written data “memory” is written is designated by the pen 16 among the written data written on the paper 3. . As a result, the writing data “memory” is specified from the plurality of writing data written on the page.
Then, the voice data after the portion of “memory” stored in the memory 45 in association with the handwritten data of “memory” specified in this manner (“memory is 128M
There is B. .. ") Are read out and the sound is reproduced from the speaker 13. Therefore, only the necessary voice data of the voice data continuously recorded for a long time can be efficiently searched for and reproduced by using the handwritten data written on the paper 3 as a clue. Further, the inclination angle of the pen 16 with respect to the tablet 17 at this time is stored in the memory 45 as the reference state of the pen 16.

Then, in the state where the sound is reproduced in this manner, as shown in FIG.
With respect to the tablet 17, a predetermined angle to the left (for example,
When the inclination is 30 °) or more, the sound electronic notebook 1 that detects the inclination performs rewind reproduction. For example, for the part that recorded the voice, "We have developed a new PC. The CPU is XXXXXX, the clock is 700 MHz, and the memory is 128 MB."
"X" means that the content is played back at a predetermined interval in a direction opposite to the normal direction while going back in the past. Then, as shown in FIG.
When the pen 16 is returned to the reference state with respect to the tablet 17,
Rewind playback is stopped, and normal audio playback is performed from that point. For example, the audio is reproduced as "XXXXXX, clock 700 MHz, memory 128 MB".

As shown in FIG. 20, the pen 16 is
When the tablet 17 is tilted by a predetermined angle (for example, 30 °) or more in the upward (rear) direction with respect to the tablet 17, the sound electronic notebook 1 that detects the tilt temporarily suspends (pauses) sound reproduction. Then, writing data such as characters and graphics can be input to the tablet 17 with the pen 16. Therefore, FIG.
As shown in FIG. 1, the user can confirm the content of the data by voice for the portion where the memo was missed first, and then perform additional writing with the pen 16 to obtain a complete memo. For example, ": 128 MB" can be entered after the portion where only "memory" is entered on the sheet 3. Thereafter, when the pen 16 is tilted upward (backward) again by a predetermined angle or more and then returned to the reference state, the pause state is released as shown in FIG. 22, and normal sound reproduction is performed.

As shown in FIG. 23, the pen 16 is
With respect to the tablet 17, a predetermined angle to the right (for example,
When the inclination is 30 °) or more, the audio electronic notebook 1 that detects the inclination performs fast forward reproduction. For example, "memory is 128
There is MB. The portion where the sound of "DVD ..." is recorded is reproduced while being fast-forwarded at a predetermined interval, such as "R ... M ... D ...". Thereafter, as shown in FIG. 24, when the pen 16 is returned to the reference state with respect to the tablet 17, fast-forward playback is stopped, and normal audio playback is performed from that point. For example, "DVD-ROM drive and floppy drive are built-in"
The sound is played. Then, the pen 16 is moved to the tablet 1
7, a predetermined angle (for example, 30
゜) When the tilt is made as described above, writing data such as characters and figures can be input to the tablet 17 using the pen 16 as described above. Therefore, as shown in FIG. After confirming the content of the data by voice for the portion that has been missed, additional writing can be performed with the pen 16 to obtain a complete memo. For example, after a portion in which only "Memory: 128 MB" is written on the sheet 3, "DVD-ROM drive and built-in floppy disk" can be written.

Further, as shown in FIG.
Is tilted downward (forward) or more with respect to the tablet 17 by a predetermined angle (for example, 30 °) or more, the audio electronic notebook 1 that detects this is played back at a slow speed. Note that, in this slow playback state, the tablet 17
It is possible to input handwritten data such as characters and figures. Therefore, the user can confirm the content of the data at the part where the memo was initially missed by slow playback of the sound, and then perform additional writing with the pen 16 to obtain a complete memo. Thereafter, when the pen 16 is again inclined downward or forward by a predetermined angle or more, and then returned to the reference state,
As shown in FIG. 27, the slow reproduction state is released, and normal audio reproduction is performed.

If it is desired to temporarily stop recording during recording, the above-described pause processing is effective.

As described above, the audio electronic organizer 1 has been described as an embodiment to which the present invention is applied. However, the present invention is not limited to this aspect and can be implemented in various aspects. For example, in the above embodiment, the tablet 1
The tilt angle of the pen 16 with respect to the tablet 17 is detected by detecting the induction signal generated by the magnetic coupling between the sense coil and the AC magnetic field generated from the pen 16 abutting on the pen 7. The means for detecting the angle is not limited to this.

For example, as shown in FIG.
The ultrasonic transducers 117 and 119 are provided on the pen tail and the pen tip, and the ultrasonic sensors 11
By providing 8, the three-dimensional position of the pen tail and the pen tip may be detected, and the tilt angle of the pen 116 may be detected based on the three-dimensional position.

As shown in FIG. 29, a pressure-sensitive tablet or an electrostatic tablet can be used as the tablet. In this case, the inclination angle of the pen 126 is detected by a gyro sensor 128 built in the pen 126. The pen tilt information from the gyro sensor 128 is transmitted from the LED 127 incorporated in the pen 126 to the infrared sensor 129 provided on the paper 123 by infrared communication. When the pen tilt angle is detected by the same method, a wire 130 connected between the pen 126 and the tablet is connected as shown in FIG.
Thus, pen tilt information may be transmitted.
