Abstract

PROBLEM TO BE SOLVED: To permit easy input manipulation by displaying inputted characters in a prescribed flickering column position of a character display means and transferring the characters displayed in the prescribed column position successively to upper column directions every time the character input is executed. SOLUTION: When a character input start button 1 in a key group 10 is pushed, a character input mode is started and the 10th column which is the prescribed position of the display 30 of, for example, 12 character columns flickers. When the character button of any among character input buttons 2 is pushed, the character is inputted to the 10th column and simultaneously the already displayed characters are shifted to the upper columns. When the character input is completed in the manner described above, the character input start button 1 is pushed again. The inputted character strings are then stored in a memory 11 and the character input mode is released. The storage contents of the memory 11 are, for example, UTOC information recorded on a disk. Since the character input columns are fixed, the movement and stop of the character input columns do not occur and the character input columns are always fixed and, therefore, the feel of manipulation is good.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus provided with character input display means and a recording / reproducing apparatus.

[0002]

2. Description of the Related Art It is very convenient if it is possible to record and manage a recording medium name which is a name unique to a recording medium and a data name which is a name of data recorded on the recording medium. It has been considered to record a recording medium name and a data name in a management area of the recording medium.

[0003] In this case, the recording device and the recording / reproducing device input the characters of the recording medium and the data name in characters, display them on the display unit, confirm them, and then record them in the management area of the recording medium. It is thought that.

[0004] By the way, devices that require character input are:
Although a display device such as a CRT, a FLD, and an LCD is provided, many devices have only one line (usually one horizontal line) of display digits due to a display space. In general, the display at the time of a character input operation on a character display device of a device capable of displaying characters of only one line of this type is as follows.

In this type of apparatus, a character input unit, a digit feed unit, and a digit return unit are provided for a character input operation.

When no character is input, the position of this digit is displayed at the most significant digit (in the case of one horizontal line, usually the left end) on a display unit such as an LCD. An underline is displayed as a cursor indicating
It flashes. When a character is input from this state, the underline moves to the next lower digit, and it flashes.
In this way, the blinking digit moves down one digit at a time as the character is input, and it is displayed that the character can be input at the blinking digit. When one line of characters is completely filled, the blinking continues at the lowest digit, and when one more character is input, the character at the highest digit is pushed out of the display.

[0007] When a character is already entered, only the first line of the character is displayed, and the character of the highest digit blinks. In this blinking digit, change characters,
Can be added. By operating the digit feed means, the blinking digit can be shifted to a lower position. To change or add a character, the character is fed to that digit by the digit feed means and a character is input.

In order to change the character before the blinking digit during input, the blinking digit is returned to the upper digit side by digit return means. Even when a character has already been input, blinking of a digit without a character is performed by blinking an underline or the like.

[0009]

However, according to the above-mentioned conventional character input method, the display of characters from the state where no character is entered to the time one line is filled and the time after the so-called overflow digit occurs are displayed. Differences occur, making operation difficult.

When a character after the blinking digit is to be changed in the case where a character has already been entered, the blinking digit is moved one digit at a time toward the least significant digit by the digit feed means to the least significant digit. After blinking, the entire character string in one line is shifted upward, which causes a difference, which makes the operation difficult.

Similarly, when the character before the blinking digit is changed, the blinking digit moves up one digit at a time to the most significant digit by the digit return means, and after the state where the most significant digit blinks, the entire line is changed. The operation is difficult because the character string is shifted toward the lower digits, causing a difference.

In particular, when the number of characters input once is larger than the number of characters that can be displayed on one line, to change the number, one of the characters before and after the digit to be changed often becomes invisible, and the change is not performed. Rai.

According to the present invention, in a recording apparatus or a recording / reproducing apparatus having a character display section having one-line character display as described above, the input operation for inputting a character of a recording medium name or a data name is facilitated. The purpose is to do so.

[0014]

According to the present invention, there is provided a management system for managing a recording medium name which is a name unique to a recording medium or a data name which is a name of data recorded on the recording medium. A recording device for recording the recording medium name or data name in a management area of a recording medium having an area, wherein a character display means for displaying a plurality of digits of characters on one line; A character input means for inputting characters of a data name, and when the recording medium name or the data name is input by the character input means, a most significant digit and a least significant digit of a character display digit of the character display means. Flashing control of the specified digit position between
A character input by the character input means is displayed at the blinking predetermined digit position, and each time a character is input, the characters already displayed at the predetermined digit position are sequentially transferred to the upper digit direction. Display control means, storage means for storing characters input by the character input means, and recording means for recording the characters stored in the storage means in a management area of the recording medium, I do.

According to the present invention having the above configuration, the fixed predetermined digit position interposed between the most significant digit and the least significant digit blinks to indicate that the fixed digit position is the character input position.
Then, when a character is input, the character input at the predetermined digit position blinks and the character previously displayed at the blinking digit and the character at the upper digit move to the upper digit. It is done as follows. In other words, the character input digit position is fixed at an intermediate digit position between the most significant digit and the least significant digit, which facilitates the character input operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a recording / reproducing apparatus according to the present invention will be described with reference to the drawings, taking a case where it is applied to a mini-disc recorder as an example.

FIG. 3 shows an example of the configuration of a mini-disc recorder to which the present invention is applied. In FIG. 3, reference numeral 21 denotes a mini disk. Mini disk 21
Is a disk 2 having a diameter of 64 mm in the cartridge 21A.
1B is housed. This mini disk 21
There are three types of discs: a read-only optical disc, a recordable magneto-optical disc, and a hybrid disc having both a read-only area and a recordable area.

A pre-groove for light spot control (for tracking control) is formed (pre-pit) on the disk 21B in advance. In particular, in this example, the pre-groove is used for tracking. Absolute address data is recorded superimposed on the wobbling signal.

The disk 21B of the mini disk 21 is rotated by a spindle motor 22. The rotation of the spindle motor 22 is controlled by a servo control circuit 25,
The disk 21B is controlled so as to rotate at a constant linear velocity. The mini-disc 21 is provided with a shutter, and when the mini-disc 21 is placed on a disc mounting tray (not shown) and loaded in the apparatus, the shutter is opened. In the case of a recordable optical disk, a recording magnetic head 23 is arranged above the shutter opening of the disk 21B so as to face the disk 21B.
An optical pickup 24 is arranged to face the lower part of the shutter opening of B.

The movement of the optical pickup 24 in the radial direction of the disk 21B is controlled by a feed motor 26. The servo control circuit 25 controls the focus and tracking of the optical pickup 24.

The system controller 20 is equipped with a microcomputer and manages the entire operation. The system controller 20 is supplied with a key input signal from the key group 10. Further, the system controller 20 controls a display operation on the display 30.

The key group 10 is used for inputting characters such as a disc name and a track name, in addition to a power button, an eject button, a play button, a pause button, a stop button, a song number selection button, and a record button on the front panel. And a character input start button, a character input button, a character feed button, a digit feed button, and a digit rewind button.

The display 30 displays time information such as the total playing time of the loaded mini-disc, the elapsed time of the currently playing song, the remaining playing time of the currently playing song, the remaining playing time of the entire song, and the like. The track number of the middle tune is displayed. For a disc on which a disc name or track name is recorded, the disc name or track name is displayed. Further, if the recording date and time of the music or the disc is recorded, the recording date and time are displayed. The above data is
The TOC (Tab) provided on the innermost peripheral side of the disk 21B
le Of Contents) and UTOC (user TOC).

The configuration of the recording / reproducing signal system of the embodiment shown in FIG.
It is devised to simplify the configuration as much as possible by using an IC. The mode of each unit is switched between a recording mode and a reproducing mode by a mode switching signal from the system controller.

At the time of recording, an audio signal is supplied to the input terminal 31. This audio signal is digitized by the A / D converter 32 at a sampling frequency of 44.1 kHz and a quantization bit number of 16 bits.

This digital audio signal is supplied to an audio compression encoding / decoding circuit 33. In the audio compression encoding / decoding circuit 33, the audio signal is data-compressed to about 1/5. In this case, as a compression technique of the audio signal, for example, a modified DCT (Modified
screate Cosine Transform) is used.

The audio signal compressed by the audio compression encoding / decoding circuit 33 is supplied to a memory controller 34.
Is once stored in a buffer memory 35 controlled by the memory controller 34. In this example, a DRAM having a data capacity of 1 Mbit is used as the buffer memory 35.

The memory controller 34 sequentially reads out the compressed data from the buffer memory 35 at a transfer speed that is about five times the writing speed, unless a track jump occurs in which the recording position on the disk 21B jumps due to vibration or the like during the recording. Then, the read data is transferred to the data encode / decode circuit 36 having the sector structure.

When detecting that a track jump has occurred during recording, the memory controller 34 stops data transfer to the circuit 36, and performs audio compression encoding / decoding.
The compressed data from the decoding circuit 33 is stored in the buffer memory 3
Store in 5 Then, when the recording position is corrected, control is performed so that data transfer from the buffer memory 35 to the data encoding / decoding circuit 36 is restarted.

The detection of whether or not a track jump has occurred can be performed by, for example, providing a vibrometer in the apparatus and detecting whether or not the magnitude of the vibration is such that a track jump occurs. Further, as described above, since the absolute address data is recorded in the pre-groove on the disk 21B of this example, the absolute address data is read at the time of recording, and a track jump can be detected from the decoded output. . Alternatively, a track jump may be detected by ORing the absolute address data with the vibration meter. When a track jump occurs, the power of the laser beam for magneto-optical recording is reduced or the power is set to zero.

The correction of the recording position when a track jump occurs can be performed using the above-mentioned absolute address data. In this case, the buffer memory 3
As the data capacity of 5, as understood from the above,
A capacity that can store compressed data corresponding to the time from the occurrence of a track jump to the correct correction of the recording position is required at a minimum. In this example, the capacity of the buffer memory 35 is 1 Mbit as described above, and this capacity is selected as having a margin so as to sufficiently satisfy the above conditions.

In this case, the memory controller 34
Performs a memory control so that data stored in the buffer memory 35 is reduced as much as possible during normal operation during recording. That is, when the data amount of the buffer memory 35 becomes equal to or more than a predetermined amount, a predetermined amount of data, for example, 32 sectors (one sector is 1 CD-byte)
Only the data of the ROM sector (about 2 Kbytes) is read from the buffer memory 35, and the memory control is performed such that a write space of a predetermined data amount or more is always secured.

The data encoding / decoding circuit 36
The compressed data transferred from the buffer memory 35 is
The data is encoded into data having a D-ROM sector structure. The data of 36 sectors including the audio data of 32 sectors is hereinafter referred to as a cluster.

The output data of the data encoding circuit 36 is supplied to the EFM and CIRC encoding / decoding circuit 3
7 is supplied. In this circuit 37, the data is subjected to encoding processing for error detection and correction, and modulation processing suitable for recording, in this example, EFM (8-14 modulation) processing.
In this example, the code for error detection and correction is CIRC of CD.
(Cross-interleaved Reed-Solomon code) with interleaving changed. The recording data is intermittent data, and a total of four linking sectors for cluster connection are added before and after the audio data of 32 sectors to form recording data of one cluster consisting of 36 sectors.

The recording data thus formed is:
It is supplied to the recording magnetic head 23 via the head drive circuit 38. As a result, a magnetic field modulated with the recording data is applied to the disk 21B (magneto-optical disk). Further, the laser beam from the optical pickup 24 is applied to the disk 21B. At the time of recording, the recording track is irradiated with a laser beam having a constant power larger than that at the time of reproduction. By this light irradiation and the modulation magnetic field by the magnetic head 23, data is recorded on the disk 21B by thermomagnetic recording. The magnetic head 23 and the optical pickup 24 are configured to be able to move in the radial direction of the disk 1 in synchronization with each other.

The data recording is performed intermittently in cluster units. The four linking sectors are also used as areas for adjusting the timing of the rise of the magnetic field of the magnetic head 23 at the start of the intermittent recording and the control of the laser power.

At the time of this recording, the output of the optical pickup 24 is supplied to the address decoder 40 via the RF amplifier 39, and the absolute address recorded in the pregroove provided along the track of the disk 21B is recorded in the pre-groove. Data is extracted and decoded. Then, the detected absolute address data is supplied to the EFM and CIRC encoding / decoding circuit 37, inserted into the recording data, and recorded on the disk. Further, the absolute address data is supplied to the system control circuit 20 and used for recognition of the recording position and position control.

A signal from the RF amplifier 39 is supplied to the servo control circuit 25, and a control signal for constant linear velocity servo of the spindle motor 22 is formed from a signal from the pregroove of the disk 21B.
2 is speed controlled.

Next, the reproduction operation will be described. That is, at the time of the reproduction, the spindle motor 22 is controlled by the servo control circuit 25 by the signal from the pre-groove at the same linear speed as at the time of the recording by the servo control circuit 25 in the same manner as at the time of the recording.

At the time of reproduction, the optical pickup 24 detects a focus error by, for example, an astigmatism method by detecting reflected light of a laser beam applied to a target track, and detects a tracking error by, for example, a push-pull method. At the same time, a difference in the polarization angle (Kerr rotation angle) of the reflected light from the target track is detected, and a reproduced RF signal is output.

The output of the optical pickup 24 is supplied to an RF amplifier 39. The RF amplifier 39 extracts a focus error signal and a tracking error signal from the output of the optical pickup 24 and supplies the same to the servo control circuit 25, binarizes the reproduction signal, and supplies it to the EFM and CIRC encoding / decoding circuit 37.

The servo control circuit 25 controls the focus of the optical system of the optical pickup 24 so that the focus error signal becomes zero, and controls the optical system of the optical pickup 24 so that the tracking error signal becomes zero. Perform tracking control.

The output of the RF amplifier 39 is supplied to an address decoder 40, which extracts and decodes absolute address data from the pregroove. Then, the absolute address data from the decoder 40 is supplied to the system control circuit 20 via the circuit 37, and is used by the servo control circuit 25 for controlling the reproduction position of the optical pickup 24 in the disk radial direction. Also, the system control circuit 20
Can be used for managing the position on the recording track where the optical pickup 24 is scanning, using the address information of the sector unit extracted from the reproduction data.

At the time of this reproduction, as will be described later,
The compressed data read from 1B is stored in the buffer memory 35.
The data is read from the disk 21B by the optical pickup 24 so that the data stored in the buffer memory 35 does not become less than a predetermined amount, for example, due to the difference in the transmission rates of the two data. Performed intermittently.

In the EFM and CIRC encoding / decoding circuit 37, the signal supplied via the RF amplifier 39 is EFM-demodulated and subjected to error correction processing. The output of the EFM and CIRC encoding / decoding circuit 37 is supplied to a sector-structured data encoding / decoding circuit 36, which deciphers the sector structure of the CD-ROM and decodes the data into compressed original data.

The output of the data encoding / decoding circuit 36 is temporarily stored in the buffer memory 35 via the memory controller 34. And the memory controller 3
No. 4 sequentially reads and reads the compressed data from the circuit 36 at a transfer rate of about 約 times the writing speed, unless a track jump in which the reproduction position jumps due to vibration or the like during the reproduction occurs. The data is transferred to the audio compression encoding / decoding circuit 33. In this case, the memory controller 34 controls writing / reading of the buffer memory 35 so that the amount of data stored in the buffer memory 35 does not become lower than a predetermined value.

When it is detected that a track jump has occurred during reproduction, writing of data from the data encoding / decoding circuit 36 to the buffer memory 25 is stopped, and only data transfer to the circuit 33 is performed. Then, when the reproduction position is corrected, control is performed so that data writing from the circuit 36 to the buffer memory 35 is restarted.

As described above, during normal operation, the memory controller 34 performs memory control so that predetermined data, which is more than necessary, is stored in the buffer memory 35 as much as possible. For example, when the data amount of the buffer memory 35 becomes equal to or less than a predetermined amount, the optical pickup 24 intermittently captures data from the disk 21B, and writes data from the data encoding / decoding circuit 36. Then, memory control is performed so that a read space equal to or larger than a predetermined data amount is always secured.

The time required to completely read data into the buffer memory 35 is about 0.9 seconds, and this data corresponds to about 3 seconds of audio data. That is, when the buffer memory is full of data, even if the signal on the disk 21B cannot be read, it is possible to continue to output the reproduction signal for about 3 seconds. In the meantime, the optical pickup is re-accessed to the original position and the signal is read again, so that the occurrence of the sound skip can be prevented.

The data decompressed by the audio compression encoding / decoding circuit 33 is supplied to a D / A converter 41, and is returned to an analog signal. This analog signal is output from the output terminal 42.

As described above, the TOC is provided on the inner periphery of the disk 21B of the mini disk 21. T
In the OC, a start address and an end address of each song on the disc, a track name as a song name, a disc name as a disc name, and the like are written. Further, in the minidisc 21, in order to manage the recorded audio signal, a recordable disc includes UTOC.
(User TOC). In this UTOC, the user can write a disk name, a track name, and the like by inputting characters.

FIG. 4 is a conceptual diagram in which a circuit portion related to the character input operation and display of the mini disk recorder is extracted. The input of the button keys of the key group 10 is read by the system control 20 using a microcomputer, and the result is read. Is displayed on the display 30 for display.

As shown in the figure, the key group 10 includes a character input start button 1, a character input button 2, a character feed button 3, a digit feed button 4, a digit return button 5, and a song number selection button 6. In addition to the above, as described above, it has button keys for driving the disc, such as a recording button and a reproduction button.

The character input start button 1 is for turning on / off the character input mode of the apparatus. Character input button 2
Is usually composed of an alphabetic button and a numeric button. In order to reduce the number of buttons, there is a case where one button is used as both an English letter button and a numeric button, and is switched and used by a switching button. The character feed button 3 includes two button keys for a plus direction and a minus direction. In this example, a character is selected from the ASCII code by the two button keys.

The digit feed button 4 shifts the input character one digit at a time in the upper digit direction (left direction). Digit return button 5
Shifts the input character one digit at a time in the lower digit direction (rightward).

The system controller 20 includes the key group 10
The input of the button key is read, and the input character is displayed on the display 30 in accordance with the input. Reference numeral 11 denotes a memory, and the input characters are temporarily stored in the memory 11 and output to the display 30. The memory 11 is a place where all the input character strings are stored, and is a place where the UTOC information is stored. In this example, a part of the memory area of the buffer memory 35 is used as the memory 11, but may be provided separately from the buffer memory 35.

Hereinafter, the character input operation and the display mode of the display in this example will be described. FIG. 5A, B, C, D
Is when the track name is entered by the user,
This is a transition of the display on the display 30 when the track name of the music number has not been input before. In this example,
One line has 12 character digits, and the blinking digit is the 10th digit.

First, when the character input start button 1 is pressed, a character input mode is entered, and the display of FIG. That is, to indicate that the input is a track name character, [TRAC
K] is displayed, and a special pattern 53 that is not in the ASCII code at the tenth digit is displayed in the 12-digit character display field 52, and the special pattern 53 flashes. , Indicates that no character has been entered. Numeral 54 denotes a calendar display of the music numbers recorded on the mini disc 21. In the example of FIG. 5, as shown in FIG. 5D, 16 pieces of music are recorded on the disc, and the track name of track number 4 is input.

There are two ways of inputting characters, one of which is a method of directly inputting characters and buttons by using the character input buttons 2, and the other is a method of inputting characters by using the character feed button 3 and A
This is a method of searching and inputting characters in the SCII code. In the following, as a case of inputting an alphabet, a character input operation will be described with reference to display contents of a character display field 52 in FIG. In FIG. 6, the character display column is surrounded by a solid line and the number of digits is displayed. However, in actual display, this box and the number of digits are not present.

FIG. 6A shows the display contents of the character display column 52 in the state of FIG. 5A. In the state of FIG. 6A,
For example, when any one of the character input buttons 2 is pressed, the character is input to the tenth digit, and at the same time, shifted by one digit to the upper digit to display as shown in FIG. The blinking display of 53 is continued.

When performing character input with the character feed button 3,
The two characters of the character feed button 3 are used to select characters before and after the character being selected and displayed from the ASCII code. Then, the selected character blinks in the tenth digit. Then, when the selected character is determined, the digit is fed by the digit feed button 4 to make the display as shown in FIG. 5B.

Thereafter, when characters are entered, the character display field 5
6C, D, and E, and when characters of 10 digits or more are input, the character of the most significant digit immediately before that is pushed out from the character display field 52 as shown in FIG. 6E. In addition, the character displayed at the tenth digit blinks.

Here, in FIG. 6E, since [I] next to the character [H] is missing, when inserting it, the digit return button 5 is operated to return the digit and display the display of FIG. 6F. To
Thereafter, when the character [I] is input, the display of FIG. 6G is displayed.

When the character input is completed as described above, the character input start button 1 is pressed again. Then, [ABCD
EFGHIJKL] is stored in the memory 11,
The character input mode is canceled. At this time, the display state of the display 30 is as shown in FIG. 5D, and the characters in the character display column disappear, and at the same time, all the recorded song numbers appear on the calendar display 54. Furthermore, [T
OC] character display 55 is illuminated.
Is changed and stored in the memory 11, but it is notified that the data has not yet been written to the disk 21B.

Next, the editing operation of the character string stored in the memory 11 will be described. FIG. 7 shows the transition of the display when characters are corrected when a track name has been input in advance for the song number. The following description will be made assuming that a character string that has been input in advance is changed from [H] to lower case in [ABCDEFGHIJKL].

When the character input start button 1 is pressed, a character input mode is set, and as shown in FIG. 7A, [ABC] is displayed in the tenth and lower digits in the character display field 52.
[A] of the digit blinks. Here, press the digit feed button 4,
The characters are sent to the character to be changed, and the display of the character display field 52 is set to a state as shown in FIG. 7B. Then, when the clear button in the character input button 2 is pressed, the characters are erased one by one,
The display state is as shown in FIG. 7C. Then, the user presses the lower case button of the character input button 4 and inputs [hijkl]. Then, the display of the character display field 52 is as shown in FIGS. 7D and 7E.

When the character correction is completed, the character input start button 1 is pressed again. Then, [ABCDEF
Ghijkl] is stored in the memory 11, and the character input mode is released. Then, in the same manner as described above, the display state of the display 30 is as shown in FIG. 5D, and the character display 55 of [TOC] is turned on, whereby the UTOC information is changed and stored in the memory 11. However, it is informed that the disk 21B has not been written yet.

In this example, the character input is in the insert mode, but may be in the overwrite mode. In that case, it is not necessary to press the clear button in the character input operation after the display state of FIG. 7B.

The above description is about the display of the track name character input operation.
The character display 51 of [ACK] is displayed, but in the case of character work of the disc name, [DI] is displayed on the display 30.
[SK] is displayed, indicating that the input operation is a disc name input operation. And also in this case,
The character input operation can be performed in exactly the same manner as the input operation of the track name.

Next, FIG. 1 and a continuation of FIG. 2 show a flowchart of the above-described character input operation and character display operation.

First, it is determined whether or not the song number selection button 6 has been pressed (step 101). If it has been pressed, the process proceeds to step 102, where the character display 51 of [TRACK] is displayed on the display 30. The selected song number in the song number calendar display 54 blinks, and then the process proceeds to step 103. If the song number selection button 6 has not been pressed, the process jumps to step 103.

In step 103, it is determined whether or not the character input start button 1 has been pressed. If not, the process returns to step 101. If the character input activation button 1 is pressed, the process enters the character input mode and proceeds to step 104. Step 10
In step 4, it is determined whether the input mode is the track name character input mode or the disc name character input mode. Step 10
1, if the music selection button 6 is pressed, the track name is in the character input mode. If the music selection button 6 is not pressed,
This is the character input mode for the disc name. In this example, the mode is determined by whether or not the character display 51 of [TRACK] is displayed on the display. When the character input start button 1 is pressed without pressing the song number selection button 6, the disc 30 is in the input mode of the disc name.
The character display 56 of [DISC] is displayed.

If it is determined in step 104 that the input mode is the track name character input mode, the flow advances to step 105 to determine whether or not a track name (song name) has already been entered. When the mode is determined, the process proceeds to step 107, where it is determined whether or not the disc name has already been entered. Then, in any character input mode, if the character of the name is not included, the process proceeds to step 106, and the display state of the display 30 is changed to the state shown in FIGS. 5A and 6A.
If the name includes characters, the process proceeds to step 108, where the display state of the character display field 52 of the display 30 is changed to the state of FIG. 7A.

After these steps 106 and 108,
Proceed to step 109. In this step 109, it is determined whether or not the character input button 2 has been operated, and when it has been operated, the process proceeds to step 110, and the character display field 52 of the display 30, as shown in FIGS.
After displaying the input character in the digit,
Performs display shifted to the left by characters. Then, step 10
Proceeding to 7, it is determined whether or not the character input activation button 1 has been pressed again. If not, the process returns to step 109.

If it is determined in step 109 that the character input button 2 has been operated, the flow advances to step 111 to determine whether the character feed button 3 has been operated. When it is determined that the character feed button 3 has been operated, the process proceeds to step 112, and the display 30 displays the character display field 52
Is displayed in the tenth digit, and then a step 11 of determining whether or not the character input activation button 1 has been pressed again
Go to 7.

If it is determined in step 111 that the character feed button 2 has not been operated, step 113
And it is determined whether or not the digit feed button 4 has been operated. When it is determined that the digit feed button 4 has been operated, the process proceeds to step 114, and the display 30 shifts the entire character by one character to the left. Thereafter, the process proceeds to step 117 for determining whether or not the character input start button 1 has been pressed again.

If it is determined in step 113 that the digit feed button 4 has not been operated, the flow advances to step 115 to determine whether the digit return button 5 has been operated. If it is determined that the digit return button 5 has been operated,
Proceeding to 16, the display 30 shifts the entire character by one character to the right. Thereafter, the process proceeds to step 117 for determining whether or not the character input start button 1 has been pressed again.

In step 117, the character input start button 1
When it is determined that is pressed, the process proceeds to step 118, and the character display 51 of [TRACK] is displayed on the display 30.
, It is determined whether the mode is the track name input mode or the disc name input mode. Then, in the track name input mode, the process proceeds to step 119, in which the input character is stored in the memory 11 as the title of the selected song number. In the disc name input mode, the process proceeds to step 120, where the disc name is stored in the memory 11 as a disc name. The contents stored in the memory 11 are UTOC information, and the character display 55 of [TOC] shown in FIG. 5D is displayed on the display 30 until the information is recorded in the UTOC recording area of the disk. This is the end of the character input mode.

The case where the present invention is applied to character display of a mini-disc recorder has been described above. However, the present invention is not limited to this example, and a character display device for displaying a plurality of digits in one line. Is applicable in all cases.

[0080]

As described above, according to the present invention, the character input digit is always fixed at the intermediate digit position of the display digit excluding the most significant digit and the least significant digit of the display digit. Therefore, the character input digit does not move or stop, and is always fixed, so that the operational feeling is good. In addition, when changing characters after inputting characters that cannot be accommodated in one line, it is possible to always check before and after the changed portion, no matter how long the character string is, making it easy to change.

In particular, it is easy to input characters even when only a relatively small number of characters of about ten and several digits can be displayed in one line.

When a digit in the character string that does not contain a character becomes a blinking digit, a pattern that does not appear as a character is displayed, so that it can be clearly seen that there is no character in that digit. In addition, a cursor such as an underline indicating an input digit is not required besides the character display section.
