Description

storage and reproduction device

The present invention relates to a storage and reproduction device, and more particularly to a storage and reproduction device using a semiconductor memory.

Now, there are various recording/reproducing devices that can be easily used to record/reproduce sounds, like writing contents of lectures or discussion papers on memo paper, such recording/reproducing devices employ semiconductor memory as a recording medium to A predetermined number of files store sound signals, and the sound signals are reproduced to output sound. More specifically, these recording/reproducing apparatuses store sound data constituted by a plurality of files in a semiconductor memory, and at the time of reproduction, sequentially reproduce the sound data starting with an earlier file.

When writing the content of the discussion paper on the memo notebook, its last content is written on the last page of the memo notebook. Therefore, when reading these contents backward, it is necessary to turn the page to read the last contents.

It is also inconvenient that, in a recording/reproducing apparatus that stores the last sound in a semiconductor memory as a last file, it is necessary to search for a file containing the last sound before reproducing the last sound.

These files stored in memory can be deleted when unnecessary. However, when a file needs to be reproduced or when new files are sequentially stored and there is no time to delete them, more important files tend to be recorded at the last write address or read address of the memory. Therefore, as more and more files are recorded, the memory will contain more files that are rarely accessed. These files which are less important are read out from memory first to be reproduced, and said last file just recorded is bound to be reproduced last.

That is, when the user wants to reproduce the sound data of the last important file, he/she needs to perform an operation for searching the target last file from a plurality of files stored in the memory. This requires complicated operations to read a desired file from a memory and reproduce it.

In order to read out and reproduce a target sound data from the memory in the aforementioned recording/reproducing apparatus using a semiconductor memory, the user needs to operate many operation buttons. For example, a playback button, a forward search button, and a backward search button, etc. More particularly, when many data pieces are recorded in the semiconductor memory, it is necessary to press the forward search button and the backward search button to select the target data piece to be reproduced before reproduction so that the index number of the target data piece is displayed on the on the display part of the device. Then, the reproduction button is pressed to reproduce the target sound data. Here, if there are multiple index numbers, the user needs to continuously press the search button in order to display the target index number.

Hereinafter, a description will be made of a storage and reproduction apparatus according to an embodiment of the present invention with reference to the accompanying drawings. In the following embodiment, a recording/reproduction apparatus using a semiconductor memory for recording or reproducing a sound signal ( Hereinafter, it is simply referred to as an IC recorder).

With reference to Fig. 1, its IC recorder 1 comprises: recording part 10, is used for converting the analog sound signal from microphone 11 into digital sound signal, and this digital sound signal is stored in semiconductor memory 9; Read the sound data stored in the semiconductor memory 9 and convert the read sound data into an analog sound signal, which is used for reproduction output from the speaker 24; 10; a display part 40 for displaying an operation state and an operation process; and an operation part 50 through which a user inputs various operations.

This recording section 10 contains: an amplifier 12 for amplifying the analog sound signal output from the microphone 11; an automatic gain controller (hereinafter referred to as AGC) circuit for adjusting the level of the sound signal amplified by the amplifier 12; an encoder 14 for converting the sound signal from the AGC 13 into sound data; and a buffer memory 15 for temporarily accumulating the sound data from the encoder 14 .

In the recording unit 10 , a microphone 11 converts the speaker's voice into an analog signal for application to an amplifier 12 . Amplifier 12 amplifies the analog signal for application to AGC 13. AGC 13 amplifies the signal from amplifier 12 so that the analog sound signal is at an appropriate level for application to encoder 14.

Since the analog sound signal applied by the AGC 13 has strong time correlation, the encoder 14 encodes the analog sound signal with a small amount of data using such as Adaptive Differential Pulse Code Modulation (hereinafter referred to as ADPCM) to generate The digital sound data and the generated sound data are added to the buffer memory 15. The encoder 14 is capable of adjusting the sound data encoding amount according to two modes. For example, in SP mode, if in SP mode, the audio signal is sampled at a sampling frequency of 8KHz, and if in LP mode, the audio signal is sampled at a sampling frequency of 4KHz, so as to adjust the audio signal encoding amount in the direction of the time axis.

The buffer memory 15 temporarily accumulates the sound data supplied from the encoder and supplies the accumulated data to the semiconductor memory 9 .

The semiconductor memory 9 is constituted by, for example, an electrically erasable/programmable read-only memory (hereinafter referred to as EEPROM), that is, a non-volatile device capable of maintaining storage contents of a memory cell even when the memory driving power is turned off. volatile semiconductor memory. The semiconductor memory 9 stores sound data supplied from the buffer memory 15 and management information (hereinafter referred to as TOC information) for performing management such as which sound data is stored in which area. More specifically, the semiconductor memory 9 is, for example, a NAND type flash memory having a storage capacity of 4M x 8 bits or 8 x 16M bits capable of storing sound data 30 corresponding to sound signals of a predetermined frequency band. minute. For example, when the memory 9 has a storage capacity of 8×16M, the voice data corresponding to the voice signal of 200 to 3400 Hz can be stored for 16 minutes in the aforementioned SP mode, and can be stored in the aforementioned LP mode. 1700Hz sound signal corresponds to 24 minutes of sound data.

On the other hand, as shown in FIG. 1, the reproducing part 20 has a decoder 21, a filter 22, and an amplifier 23 for converting the audio signal read from the semiconductor memory 9 into an audio signal. Used to amplify the sound data from the filter 22 to be provided to the speaker 24 .

The decoder 21 corresponds to the encoder 14 of the recording section 10, and decodes sound data that has been encoded by the ADDCM method to generate a so-called PAM signal. The filter 22 filters out high-frequency components beyond the sound band from the PAM signal and outputs an analog sound signal. The amplifier 23 amplifies the analog sound signal supplied from the filter 22 , and the speaker 24 is driven based on the signal from the amplifier 23 . Therefore, the sound recorded in the memory 9 is output from the speaker 24 .

The control section 30 includes: a ROM 31 containing a program for controlling the IC recorder; a microprocessor (hereinafter referred to as CPU) 32 for executing the program stored in the ROM 31 to control each section; a random access memory ( Hereinafter referred to as RAM) 34, are used for temporarily storing the time of timer 33, program execution result etc., and timer 33 wherein is used for generating clock information; Provided pulses are counted. The control section 30 performs operation control of the respective components of the device 1 in accordance with the operation settings of the operation section 50 .

The display section 40 displays the operating state of the IC recorder 1 and the sound data storage state according to a control signal from the control section 30 and includes a liquid crystal display 41 and a backlight 42 for illuminating the liquid crystal display 41 .

The operation part 50 supplies various input signals to the control part 30 when sound recording/reproduction is performed. As will be described in detail later, the operation section 50 has various operation buttons operated by the user. Operating switches and a steering wheel. In the IC recorder 1 , various output signals from these operation buttons/switches and the steering wheel are supplied to the control section 30 .

The CPU 32 of the control part 30 reads the ROM 31 according to a signal supplied from the operation part 50, executes a corresponding program, and controls each part according to the read program. For example, if a recording start button which will be described in detail later is pressed, the CPU 32 reads the ROM 31 and executes a program corresponding to the recording operation, and controls the amplifier 12, the AGC 13, the encoder 14, the display part 40, etc. according to the program that has been read out The operation causes the sound data temporarily accumulated in the buffer memory 15 to be written into a free area of the semiconductor memory. For the reproduction of sound data, the CPU 32 reads the ROM 31 and executes the program corresponding to the reproduction operation, and controls the operations of the decoder 21, the filter 22, the amplifier 23, the display part 40, etc. according to the program that has been read out, so that the operations stored in the Sound data in a predetermined area of the semiconductor memory 9 is read out and converted into an analog sound signal to be output from the speaker 24 .

Therefore, the control part 30 controls the voice data to be written into or read out from the semiconductor memory 9, and, for example, by adding an index number to identify each piece of voice data, a maximum of 99 pieces of voice data can be written to the semiconductor memory. 9 in. Based on the index number added to each sound data piece, the control section 30 controls to read out the target sound data piece from the semiconductor memory 9 .

Next, the operation part 50 of the IC recorder 1 will be explained with reference to FIGS. 1 and 2 . FIG. 2 is an external view succinctly showing the external configuration of the IC recorder 1 . The IC recorder shown in FIG. 2 is portable, having a housing 2 of a size that can be held by one hand. In this casing 2 is mounted a printed circuit board (not shown) on which the aforementioned electronic circuits, such as the recording section 10 and the reproducing section 20, etc. are mounted. On the main surface 2a of the casing 2, the aforementioned liquid crystal display 41 and the speaker 24 are mounted.

On the main surface 2 a and side surfaces of the case 2 , the IC recorder 1 has various operation buttons/switches 51 to 57 constituting the operation member 50 and the steering wheel 60 . The buttons and switches of the operation part 50 are mounted on the main surface 2a and side surfaces of the casing 2, and can be operated by left fingers while the entire IC recorder 1 is held in the left palm, so that the user can continue working with his/her right hand , such as writing, etc.

As shown in Figure 2, the operation buttons here include a FILE button 51, a MENU button 52, a PRIORITY button 53, a STOP button 54 for stopping recording or the like, a REC button 55 for starting recording, and a ERASE button of the sound data in the memory 9. These operation buttons are mounted on the main surface 2 a of the casing 2 . A slide-type HOLD switch 57 is provided on the lower half of the left side 2b of the case 2. As shown in FIG. Although not shown, the operating part 50 also includes a button for turning on the back light source 42 of the liquid crystal display 41, a volume switch for adjusting the size of the reproduced sound, an earphone jack, etc., and they are all mounted on the on the side of housing 2.

Here, the FILE button 51 is used to switch among a plurality of files in the IC recorder 1 . The term file is equivalent to a path or folder as used in a personal computer. In this embodiment, five file types are preset. That is, in this IC recorder 1, a maximum of 99 pieces of audio data can be stored for each type of file. File types can be identified by displaying different icons on the liquid crystal display 41 .

The MENU button 52 is used to operate during the stop state of recording/reproduction, so as to modify the initial setting of the IC recorder 1, such as modification of data and time, modification of the frequency band of the recorded sound data, the frequency band given according to the pressing of the operation button. Modification of beep and alarm output, modification of microphone sensitivity, etc.

The PRIORITY button 53 is pressed during the stop state of the device 1 or during the reproduction operation, so as to determine the reproduction priority of the sound stored in the memory 9, when the PRIORITY button is pressed, the index number of the target sound data such as the data being reproduced was modified to a smaller number. In this file, the sound data with the index number modified by the PRIORITY button 53 is reproduced with higher priority.

The HOLD switch 57 is used to hold the operating state or the stopped state of the IC recorder 1 . When the HOLD switch 57 is in the ON state, the IC recorder 1 is in a state of not receiving operations of the operation buttons 51 to 56 and the steering wheel 60 . The structure of the steering wheel 60 and the reproduction operation using the steering wheel 60 will be described in detail later.

Here, as shown in FIG. 3, when sound data and other data are stored in the semiconductor memory 9, these data are divided into 512 blocks, which are deletion units. These blocks are divided into the following six types: permanent blocks (1 block), 0-index level blocks (6 blocks), 1-index level blocks (6 blocks), backup blocks (1 block), working blocks (15 blocks), and PCM data block (469 blocks).

The foregoing TOC information is composed of permanent blocks, index-level blocks 0, index-level blocks 1, backup blocks, and working blocks. Sound data is written to the PCM data block.

As shown in FIG. 3 , each block consists of 16 pages (each page consists of 528 bytes): page 0, page 1, . . . , page 14, page 15. Each page is composed of a 512-byte data area and a 16-byte redundant area. There are ten blocks at most that are blocks that cannot be used for data recording and/or reproduction (hereinafter referred to as invalid blocks).

The permanent blocks are set at places other than the first and last blocks of the memory 9, other than the start and end addresses of memory writing or reading. The permanent block contains management information which is first read from the memory 9 . According to the data of the eternal block, read out the 0-index level block and the 1-index level block. Therefore, the permanent block is indispensable for reading data stored in other blocks, so the permanent block is located in a place other than the first and last addresses of the memory 9, the storage areas of the first and last addresses Has the greatest potential for damage from abnormal operating conditions such as static electricity and abnormal voltages. For example, if a block containing sound data is damaged, the data in the damaged block can be erased so that new sound data can be recorded without any problem. However, if a permanent block is damaged, no data can be read from other blocks. In order to avoid this, permanent blocks are located at locations other than the start and end address blocks of the memory 9, as described above.

In the eternal block, only page 0 contains data, while pages 1 to 15 do not contain data. More specifically, as shown in Figure 4, page 0 of the eternal block includes 4 bytes of eternal block identification data, 2 bytes of Section permanent block address, 2-byte 0-index level address, 2-byte 1-index level address, 2-byte working block start address, 4-byte dummy data, and 128-byte blank image . This blank map indicates the location of the aforementioned invalid blocks.

The 0-index level block and the 1-index level block have the same data structure and these blocks are rewritten alternately for each sound data rewriting. That is, for example, when voice data is written in the memory 9, the data in the 0-index level block is rewritten, and when other voice data is written in the memory 9, the data in the 1-index level block are rewritten, and thereafter, these blocks will be collectively referred to as index-level blocks.

As mentioned above, there are 6 index level blocks for level 0 and level 1 respectively: five blocks containing file data and one block containing level data.

FIG. 5 shows a configuration of index-level blocks having a file data including ADR data blocks of pages 0 to 11 and HDR blocks of pages 12 to 15. Referring to FIG.

Fig. 6 shows the configuration of the ADR data block, which has, for example, ID numbers 01 to 06; SP, which is used to indicate the recording mode SP according to the amount of encoding produced by the aforementioned encoder 14 for each file containing sound data Or LP; STH, which indicates the high start address of the file; STM, which indicates the low start address of the file; ENH, which indicates the high end address of the file; ENM, which indicates the low end address of the file.

For example, when six pieces of sound data are recorded, as shown in FIG. 7, in the ADR block, index numbers 01 to 06 are recorded corresponding to the six pieces of sound data. The index number is data indicating the reproduction sequence of the recorded six pieces of sound data. For each index number, the recording mode (SP) and the start address (STH, STM) and end address (ENH, ENM) of the area containing sound data are recorded. For example, as shown in FIG. 6, since the sound data of index number 01 and index number 03 have a large capacity, index number 01 includes two files, and index number 03 includes four files. In this case, for each file, a recording mode and a start address and an end address are recorded.

Fig. 7 shows the structure of the HDR block. The following content is recorded for each file; PRI represents the file priority set by the operation of the PRIORITY button 53 of the operating part 50; ALM represents the alarm ON/OFF set by the operation of the MENU button 52; AMO, ADA , AHO, AMI, and AOW indicate the month, day, hour, minute, and week when the alarm is activated. Here, as described above, the priority indicates the sound data reproduction priority when a sound data is reproduced. When the priority or alarm setting is modified by the operation of the PRIORITY button 53 and the MENU button 52, the HDR data block is modified even if the sound data is not modified.

On the other hand, as shown in FIG. 8, the index level block containing level data has a valid flag on page 0, a mode interrupt flag on page 1, a blank image on page 2, and a blank image on page 3. A blank image of an eternal block on .

The backup block is a backup for the preceding eternal block and is a copy of the eternal block. Therefore, when the eternal block is rewritten, the fallback block is also rewritten. It is possible that more than one backup block exists.

The work area is an area for temporarily recording index data during sound data recording. As shown in Figure 9, the working area has almost the same data structure as the index-level block. The working block includes an index number, SP/LP information indicating the recording mode, a high start address of sound data, a low start address of sound data, a high end address of sound data, and a low end address of sound data, each of which is defined by 1 byte configuration. In the working block, while reading data from the working block, the index level block is rewritten, and data such as the start address is directly written as it is.

The PCM block is an area where sound data is mainly recorded. As shown in FIG. 10, in the PCM data block, in addition to containing voice data, each page also records the year, month, day, hour, minute, second, and week generated by the timer 33. More specifically, 512 bytes of sound data, 1 byte of year data, 1 byte of month data, 1 byte of day data, 1 byte of hour data, 1 byte of minute data, 1 byte of second data are recorded on one page , 1 byte clock setting flag.

In the IC recorder having the above structure, if the REC button 56 is pressed when recording or reproduction is not performed, the CPU 32 controls writing of voice data into the semiconductor memory 9. Assume that six pieces of sound data have been recorded in the semiconductor memory 9, as shown in FIG.

More specifically, when the REC button 56 is pressed, the CPU 32 reads the ROM 31 and executes a program corresponding to the recording operation, so that the amplifier 12, the AGC 13, and the encoder 14 are activated, and the elapse of a predetermined time via the buffer memory 15 is delayed. The sound data of is stored in the PCM data block of the semiconductor memory 9.

For each data block, the CPU 32 stores 512 bytes of sound data and generates data of recorded year, month, day, hour and minute to be recorded in the PCM data block together with the sound data. Until the STOP button is pressed, the CPU 32 controls writing sound data in the PCM data block of the semiconductor memory 9 in the form of a sound data piece.

When the STOP button is pressed, the CPU 32 ends the control of recording sound data in the PCM data block and rewriting the TOC information of the memory 9. More specifically, index-level blocks are rewritten.

In the ADR data block of the index level block containing the file data, the CPU 32 assigns index number 01 to the 7th sound data piece and writes in the mode setting, start address, end address data. CPU 32 changes previous index numbers 01-06 into index numbers 02-07 respectively, and writes in the start address, end address, and mode setting data of each index number.

This process is shown in Figure 11. The CPU 32 assigns index number 01 to the last recorded seventh audio data piece, shifts the previous index numbers 01-06 by 1 to index numbers 02-07, and rewrites the TOC information. That is, the last sound data piece is recorded in the memory 9 with the index number 01.

Next, reproduction of sound data will be described.

When the apparatus 1 is in the stopped state, if the user presses the steering wheel shown in FIG. 2 in the direction of the arrow X, the CPU 32 restarts reproduction. That is, data is identified based on the permanent block from the permanent block of the memory 9 . The CPU 32 identifies the eternal block and reads out the data in the eternal block. It should be noted that if the CPU 32 cannot recognize the permanent block shown in FIG. 3, the CPU 32 recognizes the backup block and reads out data from the backup block.

According to the 0 index level address or the 1 index level address in the permanent block or the backup block, the CPU 32 reads the data of the index level block.

CPU 32 adopts the ADR data block control of the index level block containing the file data to read the sound data from the PCM data block. Here, the CPU 32 reads out the sound data in the order of index number 01, index number 02, index number 03, . . . More specifically, at first, according to the start address (STH, STM) and the end address (ENH, ENM) of the index number 01 in the ADR data block, the CPU 32 reads out the sound data of the index number 01. The sound data that has been read is converted into a sound signal via a decoder 21 and a filter 22 so as to be supplied to a speaker 24 . Therefore, the sound of the index number 01 is output from the speaker 24 .

CPU 32 continues to read sound data from memory 9, until the STOP button among Fig. 2 is pressed. That is, after the sound of the index number 01 is output from the speaker 24, the CPU 32 reads out the sound data of the index number 02, the sound data of the index number 03, ... in order.

As described above, as shown in FIG. 11, in the IC recorder, when new sound data is recorded, it is stored in the semiconductor memory 9 as the last sound data of index number 01, so that reproduction is performed with index number 01, index No. 02, index No. 03, ..., this is because the sound data with smaller index numbers is often more important than the sound data with larger index numbers, the aforementioned control allows the use of earlier index numbers to set important sound data piece. Therefore, there is no need to search for important latest sound pieces, thus enhancing operability.

In the IC recorder 1, it is also possible to add another sound data as an additional recording to an already recorded sound data. Here, the CPU 32 executes the processing shown in step 1 of FIG. 12 and thereafter.

For example, if the user presses the REC button 56 while the IC recorder reproduces the sound data of index number 02 (step S1), the CPU 32 starts the timer 3 and determines whether the REC button 56 is pressed for more than 1 second (step S2) . If it is determined that the REC button 56 has been pressed for more than 1 second, the CPU 32 interrupts the reproduction of the sound data of index number 02 (step S3), and if it is determined that the REC button 56 has not been pressed for more than 1 second, the CPU 32 continues reproduce.

After this reproduction is interrupted, the CPU 32 controls to start recording the sound input from the microphone 11 and write the sound data in the PCM block of the memory 9. The CPU 32 continues recording until the STOP button 55 is pressed or the storage capacity of the semiconductor memory 9 becomes full (step S5). When the STOP button 55 is pressed or the storage capacity of the semiconductor memory 9 becomes full, ie, there is no area for writing voice data, the CPU ends the recording (step S6).

After the reproduction ends, the CPU 32 executes the writing of the TOC information of the sound data (step S7). More specifically, as shown in FIG. The start addresses (STH, STM) and end addresses (ENH, ENM) of index number 01 and index number 02 existing before recording. Then, the CPU 32 controls to write the start address and the end address for indicating the new sound data recording position of the additional recording as the index number 02, and then writes the beginning of the sound data of the index number 03 and after which existed before the recording address etc. Therefore, the CPU 32 assigns index number 02 to additionally recorded new sound data and writes its start address (STH, STM) and end address (ENH, ENM).

Therefore, in the IC recorder 1, when the steering wheel 60 is operated to start reproduction, the reproduction of audio data is performed in the order of index number 01, index number 02, . . . . Here, as shown in FIG. 14, the additionally recorded sound data piece is output in the shape of index number 02 immediately after the previously recorded sound data portion of index number 02.

That is, in the IC recorder 1, it is possible to select a piece from already recorded pieces and record a new piece to be added to the selected piece, therefore, the user can record a piece to be added with a desired index number. A new slice of data on a selected one of the multiple slices already recorded. This can significantly enhance the operability, eliminate the time required for searching for a desired piece, and this additional recording can be realized without changing the operation part 50, thus without increasing the production cost.

In the above-mentioned embodiment, it has been explained based on a case where additional recording is set, and this case is to press the REC button 56 for more than 1 second while a predetermined file is read out and reproduced from the memory 9, However, this additional recording mode is not limited to this case.

For example, if the REC button 56 is pressed for a predetermined period of time (for example, 2 seconds) after the reproduction of the file of index number 02 is interrupted by the user, the additional recording mode can be set by the CPU 32. When the additional recording mode is set, the CPU 32 executes the processing of step S4 and onwards to record a new sound data in the semiconductor memory 9 with index number 02.

Then, the reproducing operation using the steering wheel 60 and the configuration of the steering wheel 60 will be explained. In the IC recorder 1 , a part of the steering wheel 60 , that is, a part of a rotation operation member described in detail later is exposed from a cutout 2C formed in the upper half of the left side 26 of the housing 2 . The steering wheel 60 includes a disc-shaped rotating operation member 61 having a rotation center shaft 62 and other parts that will be described in detail later, and most parts of the steering wheel are housed in the housing 2, and only a part of the rotating operating member 61 is cut from exposed in opening portion 2C. The rotation operation member 61 of the steering wheel 62 is rotatable about a rotation center axis 62 in directions A and B shown in FIG. 2 .

Also, the rotation operating member 61 of the steering wheel 60 is constructed in such a manner that the rotation center shaft 62 can move on the side of the housing 2 in the X and Y directions shown in FIG. 2 . In a normal state, ie, when the steering wheel 60 is in a non-operating state, the member 61 is pushed in the direction of arrow Y by a spring (not shown), so that a part of the member 61 protrudes from the cutout portion 2C. Therefore, the rotation operation part 61 of the steering wheel 60 can be operated by the user to rotate in the directions of arrows A and B shown in FIG. Press and move in the direction indicated by the middle arrow X, which will make the rotating operation part 61 located in the casing 2 .

When the rotation operation part 61 is rotated in the direction of arrow A or B shown in FIG. 2 , the steering wheel 60 provides an output signal to the control part 30 according to the rotation angle and the rotation speed. When the rotary operation member 61 is pressed in the direction of the arrow X shown in FIG. 2 , an output signal corresponding to the pressing time of the member 61 is supplied to the control member 30 . More specifically, in the IC recorder 1, the control part 30 detects the rotation direction, the rotation angle and the rotation speed of the rotation operation part 61, or detects whether the rotation operation part 61 is pressed and whether the pressing of the rotation operation part 61 exceeds a predetermined value. period. The control section 30 reads out a program from the ROM 31 based on the detection result and executes the program so as to control the operations of the various sections of the device 1 . It should be noted that the control operation of the control section will be described in detail later.

The user operates the steering wheel 60 in various situations including a case of performing various operations in reproduction or a case of modifying the initial setting of the aforementioned date and time. That is, the steering wheel 60 has a high frequency of use. In response to this situation, as shown in Figure 2, the steering wheel 60 is arranged on the side of the housing 2, so that the user can hold the housing 2 with his/her left hand, and can rotate and press with his/her left thumb alone Rotary operating member 61 protruding partially from cutout portion 2C.

15A, 15B, 16, the structure of the steering wheel 60 will be described in detail below. FIG. 15A is a front view of the steering wheel 60 , that is, an external view from the main surface 2 a of the casing 2 . Figure 15B is an external view from the rear. As shown in FIGS. 15A and 15B , the steering wheel 60 includes the aforementioned rotary operation part 61 , a base part on which the rotation operation part 61 is connected, a reed-shaped electrode 64 , and four electrodes mounted on the base part 63 . Terminals a, b, c, d.

The base member 63 is made of an insulating material and has a main surface portion 63 a fitted inside the casing 2 so that the entire steering wheel 60 is fixed to the casing 2 . As shown in FIG. 15B, the base member 63 has an elliptical cutout portion 65 having a longer axis in the directions of arrows X and Y. As shown in FIG. In the cutout portion 65, the circular rotation center shaft 62 provided at the center of one main surface 61a of the rotation operation member 61 is installed in such a manner that the shaft 62 can rotate and move along almost the same direction as the rotation center axis. A plane perpendicularly intersected by 62 moves in directions indicated by arrows X and Y in FIG. 15B.

As shown in FIG. 15A, the electrode 64 is formed of a reed that has been bent. Electrode 64 has a base end secured to base member 63 . A plurality of terminals a, b, c, and d fixed to the base member 63 are respectively connected to the control member 30 shown in FIG. 1 . Here, the terminals a and b are used to output an output signal according to the rotation of the rotary operation member 61 . Terminal d is used to provide an input signal according to pressing the rotating operation member in the direction of arrow X, and terminal c is used as a common ground for terminals a, b, and d.

When the rotary operation member 61 is pressed in the direction of the arrow X, the tip 64a of the electrode 64 moves in the direction indicated by the arrow X and comes into contact with another electrode (not shown). When the electrode 64 is in contact with the other electrode (not shown), the steering wheel 60 supplies an output signal from the terminal d to the control part 30, which signal indicates that the rotary operation part 61 is pressed by the user. When the pressing of the rotary operation member 61 is stopped, the connection between the electrode 64 and another electrode (not shown) is released, and the supply of the output signal from the terminal d to the control member 30 is terminated. The control section 30 detects an output signal supplied from the terminal d indicating that the rotary operation section 61 is pressed, and detects whether the supply of this signal from the terminal d has continued for a predetermined period of time. According to the result of the detection, the control section 30 reads out the program corresponding to the detection result from the ROM 31 and performs operation or control according to the program which has been read out.

As shown in FIG. 16 , when the rotary operation member 61 is rotated in the direction of arrow A or B, the steering wheel 60 outputs a 2-phase pulse signal. That is, if the rotary operation member 61 is rotated clockwise, that is, in the direction of arrow B, that is, the signal α is output from between the terminals a-c, and the signal β is output from the terminals b-c, the phases of the signals α and β are different from each other. Likewise, if the rotary operation member 61 is rotated counterclockwise, that is, in the direction of arrow A, a signal α is output from between terminals a-c and a signal β is output from terminals b-c, and the phases between the signals α and β are different. As shown in FIG. 16, the pulse signal is output in such a way that when the rotary operating member 61 is rotated clockwise, the signal β slightly lags behind the signal α, and when the rotary operating member 61 rotates counterclockwise, the signal α slightly lags. on the signal β. Therefore, the control part 30 can recognize the rotation direction of the rotation operation part 61 by detecting which one of the signals α and β has a lagged phase.

While the steering wheel 60 is rotating 360 degrees clockwise or counterclockwise, the signals α and β are each pulsed 15 times. That is, when the rotary operating member 61 is rotated by 1/15 turn (24 degrees), the signals α and β generate one pulse each. Therefore, the control part 30 can detect the rotation angle of the rotation operation part 61 by counting the number of pulses with the counter 35, and furthermore, the control part 30 can detect the rotation angle of the rotation operation part 61 by counting the number of pulses with the counter 35 within a predetermined cycle. spinning speed.

In the IC recorder 1 having the above structure, if the FILE button 51 is pressed before recording is performed, the control section 30 controls the reading of data in the ROM 31, and icons corresponding to the respective files are displayed on the liquid crystal display. An icon on the display screen 41 can be selected by rotating the rotation operating part 61 of the steering wheel 60 in the direction of arrow A or B in FIG. icon so that new sound data will be stored in the identified file. If the MENU button 52 is pressed before recording, the control section 30 reads out data on the initial setting from the ROM 31 and an initial setting state is displayed on the liquid crystal display 41 . In order to modify the current initial setting, the rotary operation member 61 is rotated in the direction of arrow A or B to select a target item. When the selection is completed, the rotary operation member 61 is pressed in the direction of the arrow X so that the selected item can be modified. In this state, the rotary operation member 61 is rotated and pressed to modify the initial setting.

When the REC start button of the IC recorder 1 is pressed, the IC recorder 1 enters a recording start state. When the user speaks toward the microphone 11, voice data is written in one PCM block of the semiconductor memory 9 determined by the operation of the steering wheel 60 as described above. When the STOP button is pressed, the recording status is released. When the sound data is recorded in the semiconductor memory 9, the aforementioned TOC information and data on file numbers and index numbers are generated by the control section 30 as auxiliary data or management data and written into the memory 9.

Next, reproduction of sound data recorded or stored in the IC recorder 1 will be described. In the same manner as recording, for example, the FILE button 51 is pressed so that data is read out from the ROM 31 by the control section 30 and icons corresponding to the respective files are displayed on the liquid crystal display 41. The rotation operation part 61 of the steering wheel 60 is rotated in the direction of the arrow A or B to select one of the icons on the liquid crystal display 41 . When the selection is completed, the rotary operation part 61 is pressed in the direction of the arrow X to confirm the selected icon, with the result that the sound data of the designated file stored in the PCM data block will be reproduced. On the liquid crystal display 41 of FIG. 2 , for the convenience of illustration, only 02/37 related to the index number is displayed, but in fact, various icons and time are displayed on the liquid crystal display 41 . In the example of FIG. 2, the denominator 37 represents the number of sound data pieces stored in the memory 9, and the numerator 02 represents the index number currently reproduced or capable of immediate reproduction. In this example, a file has 37 pieces of sound data stored in the memory 9 and the sound data of index number 02 is being reproduced or is in a state of being reproduced soon.

Here, when the IC recorder 1 is in the immediate reproduction state, the reproduction of the sound data of the selected index number is started by operating the rotation operation member 61 of the steering wheel 60 as follows.

When the rotary operation part 61 is rotated counterclockwise, that is, in the direction of the arrow A, the control part 30 performs a forward search. More specifically, according to the pulse number based on the signals α and β in FIG. 03/37, 04/37, 05/37|…). On the other hand, if the steering wheel 60 is rotated clockwise, ie in the direction of arrow B, the control part performs a backward search. More specifically, according to the number of pulses based on the signals α and β, the control part 30 reads out the previous index numbers (in this example, 01, 37, 36...) from the semiconductor memory 9 so as to sequentially display on the liquid crystal on the screen 41.

When the user has found the index number of the sound data to be reproduced and pressed the rotary operation part 61, the control part 30 detects the output signal provided from the terminal d of the steering wheel 60, and controls to read out the data related to the steering wheel from the memory 9. The operation of 60 operates the audio data corresponding to the selected index number, and then starts the reproduction of the audio data. In this reproduction state, if the rotary operation part 61 is pressed in the direction of the arrow X for a short period of time (hereinafter, this operation will be called a short press), the control part 30 controls to end the reproduction of the sound data. If the rotary operation part 61 is pressed in the direction of the arrow X for a period longer than a predetermined time in this reproduction state (hereinafter, this operation will be referred to as a long press), the control part 30 performs repeated reproduction which will be described in detail later.

Next, various functions regarding reproduction in the IC recorder 1 will be explained. During reproduction, the IC recorder 1 has a tail/swivel reproduction function, a repeat reproduction function, and a scan reproduction function. These functions can be selected and executed by individually operating the rotation operation member 61 of the steering wheel 60 .

FIG. 17 shows the operation of the rotary operation section 61 related to tail-swing/swing reproduction in relation to reproduction state transition. Note that in FIG. 17, the rotary operation member 61 is simply indicated as JOG. For tailing/swiveling, when reproduction is started or thereafter, the rotary operation member 61 is continuously pressed in the direction of arrow X while being rotated in the direction of arrow A or B by a predetermined angle. As shown in FIG. 7, in this embodiment, if the rotation operation part 61 is continuously pressed in the direction of the arrow X while being rotated counterclockwise, that is, in the direction of the arrow A, the control part 30 controls to perform tail-end reproduction. , while if the rotary operation member is continuously pressed in the direction of arrow X while being rotated clockwise, ie, in the direction of arrow B, control is generated to perform swivel reproduction. While the rotary operation member 61 remains pressed in the direction of the arrow X, this tail/turn reproduction operation continues, assuming, for example, that sound data is reproduced at a speed ten times faster than the normal reproduction speed. On the other hand, if the pressing of the rotary operation member in the direction of the arrow X is released and the supply of the output signal from the terminal d of the steering wheel 60 is terminated, the control member 30 ends this tailing/turning reproduction operation and shifts to the normal Mode of speed reproduction. As shown in FIG. 17, if the rotating operation member 61 is rotated clockwise, that is, in the direction of arrow B during one-sequence reproduction, or if it is rotated counterclockwise, that is, in the direction of arrow A during one-turn reproduction, Rotate, the control part 30 also controls to switch the mode to normal speed reproduction.

In the embodiment of the present invention, when the tail-end reproduction reaches the end of the sound data stored in the memory 9, control is generated to interrupt the tail-end reproduction and set the mode to the end of the audio data stored in the memory 9. The header of the last sound data. On the other hand, when the first sound data stored in the memory 9 is reached when the turnaround reproduction is reached, control is generated to interrupt the turnaround reproduction and set the mode to the head of the sound data stored in the memory 9 . Therefore, in the IC recorder 1, control is produced in such a manner that, except at the start position and the last position of the sound data stored in the memory 9, a tail-end reproduction or a turnaround reproduction will not be terminated. . For example, when sound data of index numbers 01 to 10 are stored, tail-end reproduction or wraparound reproduction will not end at sound data of index number 03.

If the rotary operation part 61 is long-pressed during reproduction of sound data, the control part 30 performs repetitive reproduction of the piece of sound data being reproduced. In the embodiment of the present invention, already reproduced pieces of sound data are repeatedly reproduced by this repetitive reproduction. During this repeated reproduction, if the rotary operation member 61 is pressed again in the direction of arrow X or rotated in the direction of arrow A or B, the repeated reproduction is released and the mode is switched to normal reproduction. Also, if the STOP button 54 or the ERASE button 56 is pressed during repeat reproduction, the repeat reproduction is canceled and the normal reproduction mode is set.

As shown in FIG. 18 , if a long press of the rotary operation part 61 is performed in the immediate reproduction state or the stop state, the control part 30 executes scan reproduction. That is, if the rotary operation member 61 is continuously pressed for a predetermined period in the direction of the arrow X in the immediate reproduction state, the control unit 30 detects the period at which the rotary operation member 61 is pressed based on the output signal from the terminal d and controls to start a scan reproduction . Here, the scan reproduction is a reproduction method as described below. When a plurality of pieces of sound data are stored in a file in the memory 9, the beginning of each piece of sound data stored in the file is intermittently reproduced and each piece of data is continuously reproduced for a predetermined period (for example, 5 seconds). Note that in FIG. 18 , the rotary operation member 61 is simply identified as JOG.

Here, by detecting, for example, detecting whether the output signal from the terminal d of the steering wheel 60 based on the pressing of the rotation operation member 61 in the direction of the arrow X continues for more than 3 seconds, the control unit 30 decides whether to perform one-scan reproduction. That is, if it is detected that the output signal from the terminal d reaches more than 3 seconds from the start of pressing the rotary operation part 61, the control part 30 controls to perform a scan reproduction, and if it is less than 3 seconds from the start of pressing, the control part 30 controls 30. A normal mode reproduction is performed.

After a scan reproduction is started, even if the pressing of the rotary operation member 30 in the direction of the arrow X is released, the scan reproduction continues. When the scan reproduction of the last sound data slice of the file being scan reproduced is completed, the control section 30 stops the IC recorder 1 at the head of the first sound data slice of the scan reproduced file.

In the scan reproduction process, if the rotary operation part 61 is rotated in the direction of arrow A or B, then by the count value of the counter 35 determined by the number of pulse signals, the control part 30 controls to switch to an earlier or later index number. Scan reproduction of sound data in which pulse signals are generated by rotation of the rotary operation member 61. During this scanning reproduction, if a target sound is heard from the speaker 24, the user presses the rotary operation member 61 in the direction of the arrow X while the target sound data is being reproduced. When the rotary operation part 61 is pressed, as shown in FIG. 18, the control part 30 controls reproduction switched to the normal mode. Therefore, by pressing the member 61 while one-scan reproduction is in progress, the target sound data can be heard from the beginning to the end. If the STOP button 54 is pressed during scan reproduction, the control section 30 releases the scan reproduction and enters a stop state according to an input signal from the operation section 50 .

In this example, if the ERASE button 56, the FILE button 51, or the PRIORITY button 53 are pressed during a scanning reproduction, the control section 30 will invalidate the input signals generated by pressing these buttons regardless of the ON/OFF state of the HOLD switch. .

In the IC recorder 1, as described above, when the rotary operation member 61 is rotated in the direction of the arrow A or B, the control member 30 detects the signals α and β based on the output from the terminals a, b, and c of the steering wheel 60, The rotation speed of the rotation operation member 61 is determined, and processing corresponding to the detected speed is performed.

FIG. 18 also shows processing performed when the rotary operation member 61 is rotated from the stopped state. As shown in FIG. 18 , when the rotation operation member 61 is rotated counterclockwise from the stopped state, that is, in the direction of arrow A, if the rotation speed of the rotation operation member 61 is slow, the control unit 30 controls to perform a slice-by-slice forward search and The index number is incremented one by one on the liquid crystal screen 41 as the search is performed. On the other hand, if the rotation speed of the rotation operation part 61 in the direction of the arrow A is fast, the control part 30 controls to perform a forward search while skipping a plurality of slices and increment the index on the liquid crystal display 41 by more than 1 each time. Number.

Similarly, when the rotation operation part 61 is rotated clockwise from the STOP state at a slow rotation speed, that is, in the direction of the arrow B, the control part 30 controls to perform a slice-by-slice backward search and decrements the index one by one on the liquid crystal display 41 Number. On the other hand, if the rotation speed of the rotation operation part 61 in the direction of the arrow B is fast, the control part 30 controls to perform a backward search while skipping a plurality of slices and to decrease the number on the liquid crystal display 41 by more than 1 at a time. index number.

Therefore, in the IC recorder 1, even if many pieces of sound data are stored in the semiconductor memory 9 with corresponding index numbers, quick rotation of the rotation operation part 61 can be performed so as to skip a plurality of index numbers, thereby quickly Find the target index number, that is, display the target index number on the liquid crystal display 41. Therefore, in this IC recorder 1, index number search before reproduction is remarkably improved, and target sound data can be reproduced quickly with simple operations.

FIG. 19 shows processing performed when the rotary operation member 61 is rotated in the direction of the arrow A or B in the sound data reproduction state. As shown in FIG. 19, in the IC recorder 1, when the rotation operation member 61 is rotated counterclockwise at a slow rotation speed from the reproduction state, that is, in the direction of the arrow A, the control member 30 controls to perform the forward direction of the slice by slice. search. More specifically, the control section 30 controls to increment the index number on the liquid crystal screen 41 one by one and start reproduction at the head of the sound data of the displayed index number. On the other hand, if the rotation operation part 61 is rotated at a fast rotation speed, the control part controls to perform the forward search while skipping many slices. More specifically, the control section 30 controls to increment the index number on the liquid crystal screen 41 by more than 1 each time and to start reproduction at the head of the sound data corresponding to the displayed index number.

Similarly, when the operating member 61 is rotated clockwise from the reproduced state. That is, when rotating in the direction of B, if the rotational speed of the rotational operation member 61 is slow, the control member 30 controls to perform a slice-by-slice backward search. More specifically, the control section 30 controls to decrement the index number on the liquid crystal display 41 one by one and start reproduction at the head of the sound data corresponding to the displayed index number. On the other hand, if the rotation speed of the rotary operation part 61 is fast, the control part 30 controls to perform the backward search while skipping many slices. More specifically, the control section 30 controls to decrease the index number on the liquid crystal display 41 by more than 1 at a time and to start reproduction at the head of the sound data corresponding to the displayed index number.

Therefore, even if many pieces of sound data are stored in the semiconductor memory 9, a simple operation of quick rotation of the rotary operation member 61 can quickly find and reproduce the head of the target sound data by skipping over a plurality of pieces of sound data. This significantly enhances the search efficiency of sound data during reproduction.

As described above, in the IC recorder 1 , various functions are assigned to the steering wheel 60 . This can improve operability and reduce the size and weight of the entire device. More specifically, the user does not have to move his/her fingers here and there, but only rotates and presses the rotation operation part 61 with his/her left thumb to complete all basic operations during reproduction. Since a large number of functions are allocated to the steering wheel 60, it is possible to reduce the number of operation buttons and switches as a whole, which visually simplifies the operation of the IC recorder 1 and achieves reduction in size and weight of the entire device.

The aforementioned storage and reproduction apparatus according to the present invention employs a semiconductor memory. The present invention is not limited to the above-described embodiments except that it can be applied to general recording devices, particularly portable devices that can be easily carried. In the above-described embodiments, a sound data recording and reproducing apparatus was specified, but the present invention may be a recording and reproducing apparatus for recording/reproducing other than sound data such as video data or the like.
