FIG. 9 shows a configuration of a circuit built in the main body 1. The key matrix 81 detects the operation of the operation button 19 of the inner lid 2 and outputs the detection signal to the keyboard controller 82 formed of a one-chip microcomputer.
Is output to. This keyboard controller 82 has 6
It operates with a clock of MHz and outputs a signal corresponding to the operation of the operation button 19 to the core chip 83. Core chip 83
Is a personal computer PC / XT of IBM Corp. that stores programs and data supplied from the CD-ROM 66.
(Trademark) compatibility processing is executed. The core chip 83 is connected to a main CPU 84 that controls each part. The CPU 84 which operates at a clock of 9.54545 MHz is connected to the program ROM 86, the EEPROM 87 and the drive controller 88 via the interface LSI 85 which operates at a clock of 28.63636 MHz.

The program ROM 86 stores programs necessary for the CPU 84 to operate. In this program, in addition to the system program, SP
A change program executed when the key 28 is operated, a program for ensuring compatibility of programs and data between different versions of playback devices (programs) (PIEX described later), and the like are also included. EE
The PROM 87 always stores data that needs to be retained even after the power is turned off. The drive controller 88 is connected to the pickup drive unit 89, and the CD-RO supplied from the pickup drive unit 89.
The reproduced signal from M66 is demodulated, the audio signal of the demodulated signal is output to the speaker 37 and the jack 4 (FIG. 2), and the video signal is output to the interface LSI 85.

The interface LSI 85 is also connected to the core chip 83, the D-RAM 91 as the main memory, the processing circuit 92, and the LCD / CRT controller 94 via a bus, and can exchange data with them. . The D-RAM 91 includes a core chip 83, an interface LSI 85, a processing circuit 92, an LCD / CR.
The data supplied from the T controller 94 or the like is stored as necessary. The processing circuit 92 performs necessary processing to generate data conforming to the RS232C standard, and outputs the data to the driver / receiver 93. Driver / Receiver 93
Is output to the plug 7 (FIG. 2). Further, the RS232C data input from the plug 7 is voltage-converted by the driver / receiver 93 and input to the processing circuit 92. The processing circuit 92 converts the input data into data that can be processed by the CPU 84.

The controller 94 controls the display-related operation. That is, the controller 94 is the LCD 100.
Alternatively, the video signal output to the video output terminal 9 is written in the D-RAM 97 via the interface LSI 95. This D-RAM 97 is a video RAM, and bit map data corresponding to the display screen is expanded. The interface LSI 95 has a built-in ROM 96, and stores therein a table used when converting the gradation and color of a display image. The converter 98 is an interface LSI
The RGB signal for computer output from the
The video signal is converted into a TSC system video signal and output to the video output terminal 9. The driver 99 is an interface LSI
The video signal output from 95 is supplied to the LCD 100 for display. The driver 99 responds to the operation of the knob 32 and the slide button 33 (FIGS. 5 and 6) with the LCD 1
00 contrast and backlight on / off control are also performed. The LCD 100 is provided on the display unit 31 described above.

Next, the operation of the embodiment shown in FIG. 9 will be described. When the operation button 19 is operated, the operated key is detected by the key matrix 81, and the detection signal is sent to the CP via the keyboard controller 82 and the core chip 83.
Input to U84. CPU 84 is a program ROM
In accordance with the program stored in 86 or the D-RAM 91, the process corresponding to the command from the operated key is executed.

For example, if it is instructed to reproduce the CD-ROM 66, the CPU 84 causes the interface LS to operate.
The drive controller 88 is controlled via I85 to drive the pickup drive unit 89. The pickup drive unit 89 includes an optical pickup 71.
To reproduce the information written in the CD-ROM 66. The drive controller 88 demodulates the signal supplied from the pickup drive unit 89. Since the time axis of the audio data of the CD-ROM 66 is compressed, the drive controller 88
Extends its time axis and outputs it to the jack 4 and the speaker 37. This allows the headphones connected to the speaker 37 or the jack 4 to drive the CD-ROM 66
You can hear the audio signal played from. The volume at this time can be adjusted by operating the volume button 5 (FIGS. 2 and 5). When headphones are connected to the jack 4, the supply of the audio signal to the speaker 37 is stopped and the audio signal is output only to the headphones.

When the speaker 37 emits sound, the speaker 37
The air on the front side (outside the outer lid 3) vibrates, and the air inside the outer lid 3 housing the speaker 37 also vibrates.
In the state where the outer lid 3 is opened, the air vibration generated outside the outer lid 3 is diverged into the open space, so that it hardly affects the air vibration inside the main body 1. Further, since the outer lid 3 is configured to be independent of the main body 1, air vibration inside the outer lid 3 is less likely to be transmitted as air vibration inside the main body 1. Therefore, it is possible to suppress the possibility that the servo of the focus actuator, the tracking actuator, the sled motor, and the like that drives the optical pickup 71 housed in the main body 1 may malfunction due to air vibration from the speaker 37.

On the other hand, the video data reproduced from the CD-ROM 66 is outputted from the drive controller 88, and the D-RAM 91 is outputted via the interface LSI 85.
Is written once. This data is processed by the core chip 83 as necessary so as to maintain compatibility with the data of the IBM personal computer. C
The PU 84 supplies the video data to the D-RAM 97 via the controller 94 and the interface LSI 95,
Remember. The video data expanded in the D-RAM 97 is transferred to the interface LSI 95 by the controller 94.
Read via the driver 99 and the LCD 10 via the driver 99.
0 (display unit 31) is output and displayed. in this case,
When an instruction to change the gradation is given, the controller 94 controls the interface LSI 95 to convert the gradation of the pixel data according to the table stored in the ROM 96 and output the converted gradation. This gradation control is performed by controlling the number of times the LCD 100 emits light per unit time.

When a CRT or the like is connected to the video output terminal 9, the controller 94 operates as an interface LSI 95.
The driver 99 is controlled via, to turn off the backlight of the LCD 100 and stop the image display. Then, the video data read from the D-RAM 97 is converted into an NTSC video signal by the converter 98 and output to the video output terminal 9. As a result, CD-
The image read from ROM66 is the NTSC system CRT.
Can be monitored at. At this time, the output of the audio signal from the jack 4 or the speaker 37 is
It continues as it is.

The video data reproduced from the CD-ROM 66 consists of 8 bits, and the upper 3 bits, the next upper 3 bits and the lower 2 bits are R, G and B, respectively.
Is assigned as the data of, and 256 kinds of colors can be expressed. Interface LSI95
The color circuit 101 included in calculates the logical sum of the 2-bit data assigned to B, adds the obtained data to the lower order of the 2-bit data, and converts the B data into 3-bit data. . Then, a total of 9 bits of video data in which R, G, and B are assigned to 3 bits are output to the converter 98.

When the interface LSI 95 has a color lookup table (CLUT) described later,
Instead of the color circuit 101, a RAM 1 as a CLUT
02 is provided. In this case, the interface LSI 9
Reference numeral 5 designates 8-bit data read from the D-RAM 97 as 18-bit data (R, G, and B are 6-bit data respectively) or 24-bit data (R, G, B).
To 8-bit data) and output to the converter 98.

Audio data, video data, text data and the like are processed by the processing circuit 92 by RS232.
The data is converted into C data and is output from the plug 7 via the driver / receiver 93 as needed.

Next, the operation of the devices P1 to P3 shown in FIG. 10 will be described with reference to the flowchart of FIG.

First, in step S0, operation processing at system startup is started, and in step S1, the process stands by until the power is turned on. When the power is turned on, the BIOS is started in step S2. As a result, each mechanical unit of each device becomes controllable. Next, in step S3, DOS is started up. DO
Next, in step S4, S installs the device driver. That is, MS-DOS is CONFIG. S
Read YS. This CONFIG. CD for SYS
CDROM as a driver for ROMXA and PIEX
XA. SYS and PIEX. SYS is described, and C
DROMXA and PIEX can be activated.

Next, in step S5, the MS-DOS
Is an AUTOEXEC. Perform BAT. This AUT
OEXEC. BAT includes SHELL. COM is described in this SHELL. COM is executed.

SHELL. In step S6, the COM determines whether or not a CD is inserted in the device.
That is, the optical actuator 71 shown in FIG. 8 is driven,
The focus servo loop is started. The focus servo loop locks when the CD is loaded in the device. On the other hand, the focus servo is not locked when the CD is not mounted. CPU84
Determines from the focus lock state whether a CD is mounted.

When it is determined that the CD is not loaded, the process proceeds to step S10, and the CPU 84 causes the LCD 100 to display a display requesting the insertion of the disc. At this time, for example, 'please ins
ert a disc and restart th
e player. 'Is displayed.
This display is displayed after the start of display in step S11.
It continues until it is determined that the second has elapsed. When 15 seconds have elapsed, the process proceeds to step S9, the power is turned off, and the process ends in step S17.

When it is determined in step S6 that the CD is inserted, the process proceeds to step S7, and it is determined whether or not the CD is a normal music CD (CD-DA). In the case of a CD-DA, audio data is recorded on its track 1. CPU8
4 reads this track 1 and, if audio data is recorded there, determines that it is a CD-DA, proceeds to step S8, and executes CDPLAYER. That is, the program for reproducing the CD-DA is executed. As a result, the user can play back the CD-DA by performing various operations.

When the reproduction of the CD-DA is completed, the process proceeds to step S9, the power is turned off, and the step S9 is performed.
At 17, the process ends.

On the other hand, if it is determined in step S7 that the CD-DA is not mounted,
In step S12, it is determined whether this CD is an MMCD, that is, a CD that can be used in this system among various CD-ROMs. The MMCD that can be used in this system is a PVD (Primary Volume Descri
ptor) is recorded. The following data, for example, is recorded in this PVD.

[0123]

[Table 1]

As shown in Table 1, the PVD byte pointers (BP) 1051 to 1053 have an Identity field.
"PIX" is described as ifing Signature. CPU84 uses PI
When X can be read, it is determined to be MMCD, and when it cannot be read, it is determined to be a CD-ROM which cannot be reproduced by this apparatus.

If it is determined in step S12 that the MMCD is not attached, the flow advances to step S15 to display an error. For example, at this time LCD
100 on'This disc is not pla
yable on theMultimedia CD
-ROM player. 'Message is displayed. This display is continued until it is determined in step S16 that 15 seconds have elapsed. When 15 seconds have elapsed, the process proceeds to step S9, the power is turned off,
The process ends in step S17.

On the other hand, in step S12, when it is determined that the MMCD is attached, the process proceeds to step S13, and a display requesting a wait for a while is displayed. At this time, for example, 'Now star
toning-up xxxxxx. Please wai
t one moment. 'Message is LCD1
00 is displayed. Here, in xxxxxx, a disk name described in the above PVD 1055 to 1086BP is displayed.

Then, in step S14, the EXEC
E. EXE or EXEME. COM search is done,
The processing is executed. After the process of step S14, the process proceeds to step S9, the power is turned off, and further step S
At 17, the process ends.

Details of the processing of the subroutine of step S14 will be described below with reference to the flowchart of FIG. The process is started in step S20, and in step S21, the mounted CD-ROM 66
From the root directory above, execute. Search for EXE (or EXEME.COM). As shown in FIG. 13, the MMCD mounted on the devices P1 to P3 has E
XEME. EXE or EXEME. COM is always available. The CPU 84 reads the EXEM. In step S22, EXE is stored in the D-RAM 91. Then step S2
Proceed to step 3 to obtain the PIEX entry point. P
The IEX accesses the entry point to execute the various service processes described above. The detailed process of acquiring the entry point will be described later with reference to the flowchart of FIG.

When the entry point is acquired in step S23, the process proceeds to step S24 and PI
The EX initialization process is performed. The PIEX initialization process will also be described later in detail with reference to the flowchart in FIG.

After the PIEX initialization process is completed in this way, the process proceeds to step S25, and the process of the application is executed. Then, when the process of the application is completed, the process proceeds to step S26, and the PIEX end process is executed. This PIEX
The details of the ending process will also be described later with reference to the flowchart in FIG. After the PIEX termination process is performed, the process proceeds to step S27, and then returns to step S14 in FIG.

That is, in this embodiment, the EXEM
E. The EXE is always read, and the initialization process and the end process described therein are executed.
In addition, the PIEX is read out as needed during application processing, and necessary processing is executed.

Details of the entry point acquisition process in step S23 of FIG. 16 will be described below with reference to the flowchart of FIG. First step S
The execution of the process is started in 30, and the device '$$ PIEX $$' is opened in step S31. The device name of PIEX is “$$ PIEX $$” in any application. If this PIEX open process is performed normally,
The handle number is acquired. If it is determined in step S32 that the handle number is not acquired, that is, if the open process of the device '$$ PIEX $$' is not normally completed, the process proceeds to step S36, and an error message is displayed. That is, at this time, for example, 'P
IEX not found. 'Message is LCD
Displayed at 100. Then, the process proceeds to step S37,
The power of the device is turned off, and the process ends.

If it is determined in step S32 that the handle number has been obtained (the open process of the device '$$ PIEX $$' has been normally completed), the process proceeds from step S32 to step S33, and the MS
-Obtain the entry point by the IOCTL service of DOS. In order to execute the above-mentioned PIEX service, it is necessary to issue an inter-segment call (CALL FAR) to the entry point managed by this MS-DOS. Therefore, in order to execute various PIEX services, it is necessary to acquire this entry point in advance. In step S34, it is determined whether or not the process for acquiring this entry point has been normally performed. If the entry point is not normally acquired, the process proceeds from step S34 to step S36 to display an error, and then in step S37, the power of the apparatus is turned off and the process ends.

When it is determined in step S34 that the entry point has been normally acquired, the process returns from step S35 to step S23 in FIG.

After the entry points necessary for executing various PIEX services are acquired as described above, the PIEX initialization processing shown in FIG. 18 is executed in step S24 of FIG.

As shown in FIG. 18, the PIEX initialization process is started from step S40. In step S41, the service number 00h and the sub-service number 04h for executing the PIEX initialization service described above are
It is set in registers AH and AL, respectively. Next, in step S42, FAR CALL to the entry point of PIEX is performed. Then, step S43
Then, the process returns to step S24 in FIG.

The PIEX1 of the device P1 shown in FIG.
When the inter-segment call for the initialization process is accepted, as shown in FIG. 20 (A), the return process is immediately performed in step S61. That is, in this case, the initialization process is immediately terminated without performing any special process.

On the other hand, in the device P2 of FIG. 10, as shown in FIG. 20B, the CLUT stored in the RAM 102 is replaced by the device P1 in step S71.
The same setting process is performed. After that, step S
The process returns from 72 to the original process.

The device P1 is capable of displaying 256 kinds of colors (fixed colors), while the device P2 is capable of displaying
The CLUT can display 256 kinds of colors selected from about 1.280 million kinds of colors (fixed colors). Therefore, the device P2 has a CLUT in the RAM 102, and is configured to display the 256 types of colors (fixed colors) designated therein.

In this case, since the application program of the device P1 does not consider the process of designating 256 kinds of colors in the CLUT, if this is applied in the device P2, the color is displayed when the PIEX2 does not exist. Can not be. However, in the present embodiment, as shown in FIG. 20B, in step S71 of PIEX2, the CLUT is initialized with a predetermined 256 kinds of colors. Therefore, the application program developed for the device P1 can be used for the device P2.

As described above, when the processing is completed while the 256 kinds of colors of the CLUT are set for the currently installed CD-ROM 66, a different CD-ROM 66 is installed in the apparatus P2. In this case, the correct color may not be displayed. Therefore, FIG.
The PIEX end processing shown in step S26 is performed as shown in FIG.

That is, the processing is started from step S50,
In step S51, the service number 00h and the sub service number 05h for starting the above-mentioned end service are
Set in registers AH and AL respectively. Step S5
In 2, the FAR CALL is issued to the entry point of PIEX corresponding to this set value. Then, the process returns to the original process from step S53.

FIG. 21A shows the PIEX1 of the device P1.
As shown in, the return process is immediately performed in step S81. That is, in this case, practically no special processing is performed. On the other hand, in the device P2, as shown in FIG. 21B, after the process of returning the CLUT to the state before the PIEX initialization is executed in step S91, the process returns from step S92 to the original process. It In this way, the CLUT is returned to the state (default state) prior to the initialization performed for the application program of the device P1, so that other CDs will be used thereafter.
-A correct color can be displayed even when a ROM is mounted.

On the other hand, in the application processing of step S25 in FIG. EXE
When data is recorded as the process of, the process shown in the flowchart of FIG. 22 is executed, for example. First, in step S101, the EEPROM is stored in the registers AH and AL.
The service number 04h for writing data to 87 and the sub service number 02h are set. Then, the application ID is set in the registers BX and CX, the address in which the application name is stored in the registers DS and SI, and the address of the buffer in which the data to be written in the registers ES and DI are stored. When such a setting is performed, step S102
At, an intersegment call is issued to the PIEX entry point corresponding to such input data. Then, the process returns from step S103 to the original process.

In PIEX1 of the device P1, FIG.
As shown in (A), when an inter-segment call is input to the entry point for writing to the EEPROM 87, data is written to the EEPROM 87 together with the application ID and the application name according to the format described above. Then, the process returns from step S112 to the original process.

On the other hand, in PIEX2 of the device P2,
As shown in FIG. 23B, when a far call to this entry point is received, a process of writing data to the HDD 111 through the MS-DOS is performed in step S121. Then, after that, in step S12
The process returns from 2 to the original process.

In this way, in the device P1, the EE
A PROM 87 is provided, and EEPR is provided in the device P2.
OM87 is not provided, but instead HDD1
11 is provided, the application program prepared for the device P1 is installed in the device P1.
Even when used in No. 2, data can be written correctly (even if the EEPROM 87 is not provided, the application program can be prevented from becoming inapplicable).

Furthermore, the following can be considered. That is, as shown in FIG. 24, for example, in the device P1, F1 to F5 are prepared as the function keys 22, and the SP key 28 is provided. On the other hand, in the device P2, F1 to F10 are provided as the function keys 22, and the SP key 28 is not provided. In such cases,
When the application program developed for the device P1 is used in the device P2, the process corresponding to the SP key 28 in the application program cannot be executed in the device P2. Also,
If the function keys F6 to F10 not provided in the device P1 are operated, the application program developed for the device P1 may malfunction.

Therefore, in such a case, as shown in FIG. 25 (A), the PIEX1 of the device P1 is made to immediately perform the restoration process in step S131 when the initialization process is called. deep. That is, in this case, substantially no special processing is performed.
On the other hand, in the PIEX2 of the device P2, as shown in FIG.
As shown in FIG. 5 (B), in step S132, the codes of the function keys F6 to F9 are set not to be delivered to the application program, and the code of the function key F10 is set to the device P.
To read the code of SP key 28 in 1,
The BIOS is replaced, and then the original processing is returned from step S133.

With this arrangement, in the device P2, the function key F10 is changed to the SP in the device P1.
It can be used in place of the key 28, and even if the function keys F6 to F9 are operated, the application program developed for the device P1 is prevented from malfunctioning in the device P2.

FIG. 26 schematically shows the above processing. That is, when the key matrix 81 outputs a signal corresponding to the operated key to the keyboard controller 82, the keyboard controller 82 supplies the data corresponding to this input to the D-RAM 91 and temporarily stores it.
In the D-RAM 91, the BI is normally stored in the area 91A.
Reference is made to the OS key table.
Therefore, normally, the BIOS key table is referred to,
Normal processing in the device P2 is executed.

On the other hand, when the application program developed for the device P1 is used in the device P2, the description in the area 91A of the D-RAM 91 is rewritten to the description for referring to PIEX. Therefore, when the application program for the device P1 is applied, the key table of PIEX2 is referred to in response to the input from the key matrix 81. As a result, the application program developed for the device P1 can be executed by the device P2 as well.
It can be used correctly.

The case where the present invention is applied to a CD-ROM reproducing device has been described above as an example, but the present invention can also be applied to other information processing devices.
