Then, the CP in the MD device of the first embodiment
The processing operation of U217 will be described with reference to FIGS. FIG. 4 shows the CPU 217 in the MD device of the first embodiment.
5 is a flowchart of a main routine showing the main processing operation of FIG.

In FIG. 4, when the power source of the MD device is turned on, the disc data relating to the discs existing in the MD device, for example, the discs held in the carrier 5 should be stored in any of the storing portions 70a to 70d. Whether the data is a disk or which storage section 70a to 70d stores the disk, etc. is stored in a memory section (not shown) provided inside the CPU 217 by the backup power supply of the vehicle. Is determined (step S1
1). Although the disk data is held in the memory unit provided inside the CPU 217 in step S11, the memory unit may be connected to the outside of the CPU 217.

If the disk data is not stored in the memory unit in step S11, various sensors arranged in the MD device, for example, the loading completion sensor 4c, the disk mounting completion sensor 4e, and the stock completion sensors 71a to 71d. Disk data is created based on the detection results such as the above, and the created disk data is stored in the memory unit (step S12). If a disk to be stored in each designated area based on the disk data exists in the device, the corresponding No. The lamps 103a to 107a are turned on. The user is The presence or absence of a disc in the corresponding designated area is determined based on whether or not the lamps 103a to 107a are lit,
No. The mode is judged by the keys 103 to 106 or the α key 107.

Α key 107 or No. Keys 103-10
It is determined whether any one of 6 is pressed (step S13). α key 107 or No. Keys 103-106
If any of the above is pressed, it is determined whether or not the corresponding disk corresponding to the pressed key exists in the device (step S14).

If the disc is present in the device, it is determined whether or not the depressed key depressed in step S13 is the α key 107 (step S15).
If the α key 107 is pressed, step S13
A timer that waits for the pressing time of the pressed key is started (step S16), and it is determined whether the pressed key is finished in step S13, that is, the key is turned off (step S16). S17). If the pressed key is not turned off, step S16
It is determined whether or not the timer started in step 3 has timed out (step S18). If the timer has not timed out, the process proceeds to step S17. However, if the timer has timed out (that is, if the key is long-pressed), the timer is reset (step S19), The process shifts to the eject mode described later (step S20), and after the eject mode ends, the process shifts to step S13.

As will be described later, in the eject mode, the No. pressed in step S13 is selected. Key 103-
Single eject mode shown in FIG. 7 in which only the disc corresponding to 106 or α key 107 is ejected from the device, and all eject mode in FIG. 9 in which all the discs stored in the device are ejected from the device And one of these modes is preselected.

If the pressed key is turned off in step S17 (that is, if the key is pressed for a short time), the timer started in step S16 is reset (step S21), which will be described later. After shifting to the play mode (step S22), the process shifts to step S13 after the play mode ends.

As will be described later, in the play mode, the No. pressed in step S13 is selected. Keys 103-106
Alternatively, there are a single play mode shown in FIG. 11 in which only a disc corresponding to the α key 107 is played, and an all play mode shown in FIG. 12 in which all discs housed in the device are played sequentially. Is selected in advance.

If the disk data is held in the memory portion in step S11, the process proceeds to step S13. In step S13, the α key 107 or the No.
If the keys 103 to 106 have not been pressed, the process proceeds to step S13.

In step S14, step S13
If the corresponding disk corresponding to the push key of No. does not exist in the device, it is determined whether the α flag is "1" (step S23). If the α flag is not "1", the mode shifts to the stock mode described later (step S24), and after the stock mode ends, the flow shifts to step S13.

As will be described later, in the stock mode,
The No. pressed in step S13. Keys 103-10
6 or the single stock mode shown in FIG. 5 in which the disc inserted from the disc insertion slot 2 is stored only in the free designation region corresponding to the α key 107, and the disc insertion port 2 is inserted into the empty designation region remaining in the device. There is an all-stock mode shown in FIG. 6 in which inserted discs are sequentially stored, and one of these modes is selected in advance.

If the α flag is "1" in step S23, the MD device is functioning as a single-player player, so the mode is not changed to the stock mode.
Control goes to step S13.

If the pressed key is not the α key 107 in step S15, it is determined whether or not the α flag is "1" (step S25). If the α flag is not "1", the process proceeds to step S16. If the α flag is "1", the process proceeds to step S13.

Therefore, according to the MD device of the first embodiment of the present invention, when the user is No. Based on whether or not the lamps 103a to 107a are lit, the presence / absence of a disk associated with each designated area is determined, and a No. for designating an empty designated area is designated. Keys 103 to 1
When the 06 key or the α key 107 is pressed, the mode shifts to the stock mode except when the α flag is “1”, and the disc number stored in the apparatus is designated as No. Key 103-
When the 106 or α key 107 is pressed and the pressing time of the pressing key is long, the mode is changed to the eject mode, and when the pressing time of the pressing key is short, the mode is changed to the play mode. Even if a function key used for switching is not provided individually, No. Whether or not the lamps 103a to 107a are turned on and No. Key 103-
This can be covered by the medium designating keys of the 106 and the α key 107, and the key space in the escutcheon 100 can be secured and the input operation in the mode setting by the user can be remarkably improved.

In the eject mode, α
When the flag is “1”, pressing the α key 107 is effective, but No. Pressing the keys 103 to 106 is invalid,
In the play mode, the α flag is "1".
In this case, pressing the α key 107 is effective, but No. It goes without saying that pressing the keys 103 to 106 is invalid.

Further, as described above, the CPU 21
In No. 7, if there are discs in the device, N for all discs stored in the device
o. Although the lamps 103a to 107a are turned on, even if a disc other than the α disc is present in the apparatus with the α flag being “1”, the No. related to the other discs. The lamps 103a to 106a are turned off, and the No. corresponding to the α disk is set. Only the lamp 107a may be lit and displayed. α when the α flag is “1”
Since disks other than the disks cannot be accessed, this kind of control does not give unnecessary choices to the user, and when the user mistakenly sets the α flag to "1", No. Keys 103 to 1
By reducing the frequency of pressing 06 and moving to step S13 in the processing operation of step S25, the loss time due to the processing operation can be steadily shortened.

Further, as described above, the No. Key 10
3 to 106 or the α key 107 is pressed for a long time to switch to the eject mode, and a short press to switch to the play mode, but a short press may switch to the eject mode and a long press to switch to the play mode. In addition, No.
Pressing the keys 103 to 106 or the α key 107 twice may shift to the eject mode, pressing once may shift to the play mode, or vice versa.

Now, the stock mode of step S24 shown in FIG. 4 will be described with reference to FIGS.

In the stock mode, as described above, the No. pressed in step S13 shown in FIG. The single stock mode shown in FIG. 5 in which the disc inserted from the disc insertion slot 2 is accommodated in an empty designated area corresponding to the keys 103 to 106 or the α key 107, and the disc insertion slot is set in the empty designated area remaining in the device. There is an all-stock mode shown in FIG. 6 in which discs inserted from No. 2 are sequentially stored, and one of these modes is selected in advance as described above.

Now, the single stock mode will be described with reference to FIG. FIG. 5 is a flowchart showing the processing operation of the CPU 217 in the single stock mode.

In FIG. 5, "STOCK MODE" is displayed on the display 117 to notify the user that the stock mode has been entered (step S3).
1) It is determined whether or not there is a disk in the carrier 5 of the device (step S32). If there is a disc in the carrier 5, the carrier 5 is moved so that the disc in the carrier 5 is stored in the original storage portion (step S33), and the carrier 5 faces the disc insertion slot 2. To the insertion port position (step S
34), a timer that waits for a disc to be inserted from the disc insertion slot 2 is started (step S35), and it is determined whether a disc has been inserted from the disc insertion slot 2 (step S36). Incidentally, after the processing operation of step S34, a guide display prompting the user to insert a disc into the disc insertion slot 2 may be displayed on the display 117. In this case, the guide display is turned off when a disc is inserted through the disc insertion slot 2.

If the disc has not been inserted through the disc insertion slot 2, it is determined whether the timer started in step S35 has timed out (step S37). If the timer has not timed out, the process proceeds to step S36. If the timer has timed out, the timer is reset (step S38) and the carrier 5 at the insertion port position is opened in the storage section 70b. To the position opposed to the unit, that is, the standby position (step S39), and the "STOCK MODE" display being displayed on the display unit 117 is turned off to notify the user that the stock mode has ended (step S40). ), The stock mode is terminated and the process proceeds to the main routine.

If a disc is inserted through the disc insertion slot 2 in step S36, the timer started in step S35 is reset (step S41), and the key pressed in step S13 in FIG. Is the α key 107, that is, it is determined whether α has been designated (step S42). If α has not been designated, the inserted disc is stored in the storage units 70a to 70d corresponding to the key pressed in step S13 (step S43), and the storage units 70a to 70d storing the disc are stored. Corresponding No. Keys 103 to 1
Applicable No. 06 The lamps 103a to 106a are turned on (step S44), and the process proceeds to step S39.

If it is determined in step S42 that α has been designated, the inserted disc is mounted in the player unit 6 (step S45), the α flag is set to "1" (step S46), and the α disc is set. Corresponding α key 1
No. 07 No. The lamp 107a is turned on (step S4
7), P in the single play mode shown in FIG. 11 described later
Move to 1.

If there is no disk in the carrier 5 in step S32, the process proceeds to step S34.

According to the single stock mode, N
o. The disc inserted from the disc insertion slot 2 can be stored in the empty designated area designated by the keys 103 to 106 or the α key 107.

Now, the all stock mode will be described with reference to FIG. FIG. 6 is a flowchart showing the processing operation of the CPU 217 in the all stock mode. It should be noted that the same operation as that in the single stock mode shown in FIG.
The description of the processing operation is omitted.

In step S44 of FIG. 6, Nos. Corresponding to the storage units 70a to 70d in which the insertion disc is stored.
No. of keys 103 to 106. Lamps 103a to 106a
Is turned on and it is determined whether or not there is an empty storage section in the device (step S51). If there is a vacant storage section in the device, the next vacant storage section in which the inserted disc can be stored is designated in a predetermined order (step S52), and step S34 is performed to wait for the inserted disc to be stored in the vacant storage section. Move to.

The predetermined order means, for example, from the top of the plurality of storage areas provided in the stocker 7 (the storage section 70).
a (# 1) → storage unit 70b (# 2) → storage unit 70c (#
3) → storage section 70d (# 4) → storage section 70a (# 1) →
…) Or from the bottom (storage 70d (# 4) → storage 7)
0c (# 3) → storage section 70b (# 2) → storage section 70a
(# 1) → storage section 70d (# 4) → ...) or the standby position of the disk (storage section 70b (# 2)) and the order is from top to bottom. Then, the empty storage section designation in step S52 may be performed for the empty storage section next to the storage section in which the disk storage was performed immediately before in the above-described order, or the disk storage is performed immediately before. Regardless of which storage unit is used, the storage unit may be started from the youngest empty storage unit based on the above order.

In step S51, if there is no empty storage section in the device, "NEXT α-MODE" for notifying the user that the disc to be inserted next in the device is automatically designated as α. Is displayed on the display device 117 (step S53), and α is designated so that the disc to be inserted next is loaded in the player unit 6 (step S5).
4) and shifts to step S34.

According to the all-stock mode, the No. corresponding to the empty designated area is set. When the keys 103 to 106 or the α key 107 are pressed, the disks inserted in the device can be sequentially stored in all the empty designated areas in the device.

According to the all stock mode,
If it is desired to stop the storage of the disc on the way, the stock mode cannot be ended unless the disc insertion waiting timer started in step S35 times out. Therefore, even during the stock mode, for example, the stock mode is ended in response to pressing a predetermined key twice or pressing two types of keys at the same time, or pressing a key unrelated to the stock mode. Is also good. In this case, the key press monitoring process may be provided after the negative determination process of step S37. Even if there is an empty storage unit in the device, the disk storage is not completed until the timeout occurs. The stock mode can be quickly terminated when the user wants to cancel.

Now, the eject mode of step S20 shown in FIG. 4 will be described with reference to FIGS.

As described above, the eject mode is set to the No. pressed in step S13 shown in FIG. The single eject mode shown in FIG. 7 in which only the disks corresponding to the keys 103 to 106 or the α key 107 are ejected from the apparatus, and all the disks stored in the apparatus are sequentially ejected from the apparatus. There is an all-eject mode shown in (1), and one of these modes is selected in advance as described above.

Now, the single eject mode will be described with reference to FIGS. 7 and 8. 7 and 8 are flowcharts showing the processing operation of the CPU 217 in the single eject mode.

In FIG. 7, in order to notify the user that the eject mode has been entered, "EJECT MOD"
"E" is displayed on the display 117 (step S6
1), it is determined whether or not the α flag is "1" (step S62). If the α flag is not "1", it is determined whether or not there is a disk in the carrier 5 (step S63). If there is a disc in the carrier 5, the disc shown in FIG.
No. pressed in step S13 shown in FIG. Key 103
~ 106 or the corresponding disk N corresponding to the α key 107
o. It is determined whether or not the disc and the disc in the carrier 5 are the same disc (step S64).

If the discs are the same, the disc No. from the disc insertion slot 2 will be used. Is ejected to the reload position (step S65), the auto-reload timer that waits for the removal of the disc at the reload position is started (step S66), and whether the auto-reload timer has exceeded a predetermined time, for example, 10 seconds. It is determined (step S67). If 10 seconds has not elapsed, it is determined whether the disk at the reload position has been pushed into the device (step S6).
8). If the disc has not been pushed into the apparatus, it is determined whether the disc at the reload position has been removed (step S69). If the disc at the reload position is removed, the process proceeds to E1 shown in FIG. 8 described later.

If the α flag is "1" in step S62, or if there is no disk in the carrier 5 in step S63, the process proceeds to step S65.

Further, in step S64, the corresponding disk N
o. If the disc of the carrier 5 and the disc of the carrier 5 are not the same disc, the disc of the carrier 5 is stored in the original storage portion (step S70), and step S6 is performed.
Go to 5.

If the auto-reload timer has elapsed for 10 seconds in step S67, or if the disk in the reload position has been pushed into the apparatus in step S68, it will be shown in FIG. 8 described later. Move to E2. If the disk at the reload position is not extracted in step S69, step S6
Move to 7.

In E1 shown in FIG. 8, it is determined whether or not the disk extracted in step S69 shown in FIG. 7 is an α disk (step S81). If the extracted disk is an α disk, the α flag is set to “0” (step S82), and the No. corresponding to the α key 107 is set. The lamp 107a is turned off (step S83), the auto reload timer started in step S66 shown in FIG. 7 is reset (step S84), and the carrier 5 at the insertion opening position is moved to the standby position (step S8).
5) In order to notify the user that the relevant eject mode has ended, the “EJECT MOD” currently displayed is displayed.
The E "display is turned off (step S86), the eject mode is terminated, and the process shifts to the main routine.

At E2, if 10 seconds have elapsed in step S67 shown in FIG. 7, or if the disk has been pushed into the apparatus in step S68, the disk in the reload position is replaced. An auto-reload operation of pulling in and holding the carrier 5 is performed (step S87), and it is determined whether or not the auto-reloaded disk is an α disk (step S87).
88).

If the auto-reloaded disc is an α disc, the disc is mounted on the player unit 6 (step S89), and the auto-reload timer started at step S66 shown in FIG. 7 is reset (step S90). , And proceeds to step S86.

If the auto-reload disc is not the α disc in step S88, the disc is stored in the original storage portion (step S91), the auto-reload timer is reset (step S92), and the original storage is restored. The carrier 5 at the position facing the opening of the section is moved to the standby position (step S93), and step S8 is performed.
Go to 6.

According to the single eject mode,
No. Only the disc designated by the keys 103 to 106 or the α key 107 can be ejected from the apparatus.

Then, the all eject mode is shown in FIG.
And it demonstrates based on FIG. 9 and 10 are flowcharts showing the processing operation of the CPU 217 in the all-eject mode. It should be noted that the same operation as that in the single eject mode shown in FIGS. 7 and 8 is denoted by the same reference numeral, and the description of the processing operation is omitted.

At step S66 of FIG. 9, the auto reload timer is started, and it is determined whether the auto reload timer has passed 10 seconds (step S1).
01). If the auto-reload timer has not elapsed for 10 seconds, it is determined whether the disk at the reload position has been pushed into the device (step S102). If the disc has not been pushed into the apparatus, it is determined whether the disc at the reload position has been removed (step S103). If the disc at the reload position is removed, the process proceeds to E3 shown in FIG. 10 described later.

If the disc is not removed in step S103, the process proceeds to step S101.
If 10 seconds have elapsed in step S101,
The process moves to E4 shown in FIG. 10 described later.

If the disk at the reload position is pushed into the apparatus in step S102, the process proceeds to E5 shown in FIG. 10 described later.

At step S84 of E3 shown in FIG. 10, the auto-reload timer is reset to determine whether or not an ejectable disc is present in the device (step S104), and the ejectable disc is present in the device. If not, the process proceeds to step S85. If an ejectable disc exists in the device, the next corresponding eject disc is designated in a predetermined order (step S105), and E6 shown in FIG. Move to.

The predetermined order in the all-eject mode means that, when the α flag is "1", the α disc is preferentially given first, and then the disc of the storage section 70a (# 1) → the storage section 70b (#). 2) Disk → storage section 70c
Disc (# 3) → Disc 70d (# 4)
And so on. If the α flag is not "1", the disc in the storage unit 70a (# 1) → the storage unit 70
b (# 2) disc → storage unit 70c (# 3) disc → storage unit 70d disc (# 4) → storage unit 70a
The discs are sequentially ejected from the designated discs in the order of (# 1) disc. Needless to say, this order is not limited to the above order and may be any order.

At E4 shown in FIG. 10, the disk is returned to the original designated area in the same manner as the processing operation in the single eject mode described above, and then the process proceeds to step S86.

At E5 shown in FIG. 10, a reloading operation is performed to store and hold the pushed disk in the carrier 5 (step S106), and it is determined whether or not the reload disk is an α disk. (Step S107). If the reload disc is an α disc, the process proceeds to step S89. If the reload disc is not the α disc, the disc is stored in the original storage unit (step S108), and the process proceeds to step S84. It should be noted that the CPU 217 may recognize the disc stored in the original storage portion in step S108 as a disc that cannot be ejected at least until the all-eject mode is once released.

According to the all-eject mode, N
o. All the discs in the device can be sequentially ejected from the device in response to the pressing of the keys 103 to 106 or the α key 107, and any disc can be left in the device.

When the disk is reloaded by pushing the disk in as described above, the reloaded disk is regarded as a non-ejectable disk at least until the all-eject mode is released.
Since the PU 217 recognizes it, for example, the disc No. You can significantly reduce the frequency of situations in which the specified disc is ejected to the reload position and the user visually checks the label of the disc at the reload position, resulting in the disc not being the disc to be ejected. , Very convenient for users.

According to the all-eject mode, if it is desired to stop the ejection of the disc on the way, the eject mode cannot be terminated unless the auto-reload timer started at step S66 times out. Therefore, even during the eject mode, for example, the predetermined mode key is pressed twice, or two types of keys are simultaneously pressed, or the eject mode is ended in response to pressing a key unrelated to the eject mode. Is also good. In this case, the key press monitoring process may be provided after the negative determination process of step S103. Even if there is an ejectable disc in the device, the disc is ejected halfway without waiting for the timeout. If the user wants to cancel, the eject mode can be quickly ended.

If the affirmative determination is made in step S102, the process may move to E4 in FIG.

Now, the play mode of step S22 shown in FIG. 4 will be described with reference to FIGS. 11 to 13.

In the play mode, as described above, the No. pressed in step S13 shown in FIG. The single play mode shown in FIG. 11 in which only the disc corresponding to the keys 103 to 106 or the α key 107 is played, and the No. Keys 103-106
There is an all play mode shown in FIGS. 12 and 13 in which all the discs accommodated in the device are sequentially played in response to the depression of the button. As described above, one of these modes is selected in advance.

Then, the single play mode is shown in FIG.
It will be described based on. FIG. 11 is a flowchart showing the processing operation of the CPU 217 in the single play mode.

In FIG. 11, "PLAY MODE" for notifying the user that the play mode has been entered is displayed on the display 117 (step S111), and α is displayed.
It is determined whether the flag is "1" (step S1)
12). If the α flag is not "1", the carrier 5
It is determined whether or not there is a disk inside (step S11).
3). If there is a disc in the carrier 5,
No. pressed in step S13 shown in FIG. Key 1
Corresponding disc No. It is determined whether or not the disc and the disc in the carrier 5 are the same (step S114).

The disk in the carrier 5 and the corresponding disk No. If the disc is the same as the disc, it is determined whether the disc is loaded in the player unit 6 (step S115). If the disc is loaded in the player unit 6, a play operation is performed on the disc loaded in the player unit 6 (step S11).
6), the "PLAY MOD" displayed on the display 117.
The "E" display is turned off (step S117), the play mode is ended, and the process proceeds to the main routine. During the play operation of step S116, the No. lamps 103a to 107a corresponding to the disc currently playing are blinked. Display it.

If the α flag is "1" in step S112, that is, it is determined that the player unit 6 is loaded with the α disc, and the process proceeds to step S116.

Further, in step S114, the corresponding disc number. If the disc No. and the disc in the carrier 5 are not the same, the disc in the carrier 5 is stored in the original storage unit (step S118), and the disc No. The disc in the carrier 5 is held in the carrier 5 (step S119), the disc in the carrier 5 is mounted in the player unit 6 (step S120), and step S116.
Move to.

If there is no disc in the carrier 5 in step S113, the process proceeds to step S119. If no disc is loaded in the player unit 6 in step S115, the process proceeds to step S120.

According to the single play mode, N
o. Only the disc designated by the keys 103 to 106 or the α key 107 can be played.

Next, the all play mode is shown in FIG.
2 and FIG. 13. 12 and 13 are flowcharts showing the processing operation of the CPU 217 in the all play mode. It should be noted that the processing operations that are the same as those in the single play mode shown in FIG.

In step S111 of FIG. 12, "PLAY"
"MODE" is displayed on the display 117 and it is determined whether or not the α flag is "1" (step S12).
1). If the α flag is not "1", step S in the figure
If the α flag is "1", the process proceeds to P3 shown in FIG. 13 described later.

When the play operation for the disc mounted in the player unit 6 is completed in step S116, the process moves to P2 shown in FIG. 13, which will be described later.

In P2 shown in FIG. 13, it is determined whether or not the α flag is "1" (step S122).
If the α flag is not "1", it is determined whether or not there are a plurality of disks in the device (step S123). If there are no more than one disc in the device, the display 11
The "PLAY MODE" display being displayed on 7 is turned off (step S124), the play mode is ended, and the process shifts to the main routine.

If the α flag is "1" in step S122, the process proceeds to step S124.

If there are a plurality of discs in the device in step S123, it is determined whether or not the performance for all the discs in the device has been completed (step S125). If the performance on all the discs in the device has been completed, the process proceeds to step S124. If the performance on all the discs in the device has not been completed, the performance currently mounted on the player unit 6 is completed. The disk for which the (play operation) has been completed is stored in the original storage section (step S126), and the next disk to be played in the predetermined order is designated (step S127).
The process moves to P4 shown in FIG. The predetermined order is
... Disk of storage section 70a (# 1) → storage section 70b (#
2) Disc → storage unit 70c (# 3) disc → storage unit 70d (# 4) disc → storage unit 70a (# 1)
The discs are played in this order, and the discs specified according to the sequence are played sequentially.

According to the all play mode, the No.
By pressing the keys 103 to 106, it is possible to sequentially reproduce all the disks stored in the device.

The determination process of step S125 in FIG. 13 may be omitted, and the processing operation of step S126 may be executed immediately after the positive determination of step S123. Further, the predetermined order in the all-play mode may be a random order selected by a random method.

Now, the play interrupt process performed during the play operation of step S116 shown in FIGS. 11 and 12, which is the main object of the present invention, will be described with reference to FIG. Figure 1
4 is a flowchart showing the processing operation of the CPU 217 in the play interrupt processing.

The play interrupt process is step S11.
6 is a process that makes it possible to switch the disc being played to another disc in response to a predetermined key operation during the play operation or to switch to the stock mode or the eject mode. An interrupt is executed every time.

In FIG. 14, the α key 107 or No. It is determined whether or not the keys 103 to 106 have been pressed (step S131). The currently playing disc is the No. The corresponding disk No. corresponding to the keys 103 to 106 or the α key 107. It is determined whether or not the disc is the same as the disc (step S132). The disc currently playing is the disc number. If it is the same as the disc in step S131, a timer that waits for the pressing time of the key pressed in step S131 is started (step S133), and it is determined whether the pressing of the pressing key is completed, that is, whether the key is turned off. (Step S134).

If the pressed key is not turned off, it is determined whether the timer started in step S133 has timed out (step S135).
If the time-out has occurred (if the key has been pressed for a long time), the performance of the currently playing disc is stopped (step S136), and the playing disc currently mounted on the player unit 6 is designated as the eject disc ( (Step S137), the play interrupt process is terminated, and the process shifts to the eject mode of step S20 shown in FIG. 4 described above.

If it is not timed out in step S135, the process proceeds to step S134, and if the pressed key is turned off in step S134 (if the key is pressed for a short time), the current performance. The performance on the inner disk is stopped (step S138), and the play interrupt process is terminated.

Further, in step S131, No. Key 1
If the 03-106 or the α key 107 is not pressed, the play interrupt process is ended.

In step S132, the disc currently playing is the disc number. If it is not the same as the disc of No. 1, the performance operation for the disc currently being played is stopped (step S139), and it is determined whether or not the α flag is "1" (step S140). α flag is "1"
If so, the play interrupt process ends.
If the α flag is not "1", the No. pressed in step S131. The corresponding disk No. corresponding to the keys 103 to 106 or the α key 107. It is determined whether or not the disk of (1) is present in the device (step S141).

In the device, the corresponding disk number. If there is a disc of the corresponding disc number. The disc is designated as a performance disc (step S142), the play interrupt process is terminated, and the process shifts to the play mode of step S22 shown in FIG.

Further, in step S141, the corresponding disc No. If there is no disc of the corresponding disc number. A designated empty area such as a storage unit corresponding to is designated (step S143), the play interrupt process is terminated, and the process shifts to the stock mode of step S24 shown in FIG. It should be noted that, after the negative determination in step S141, the play interrupt process may be terminated.

According to the play interruption processing, the No. Keys 103 to 106 or α key 1
When No. 07 is pressed, the corresponding No. If a disk corresponding to the keys 103 to 106 or the α key 107 exists in the device, the No. Depending on the pressing time of the keys 103 to 106 or the α key 107, the eject mode for ejecting the corresponding disc from the apparatus, or the play mode for continuing playing by switching from the currently playing disc to the corresponding disc, No. Key 103-
If the disk corresponding to the 106 or α key 107 does not exist in the device, the No. Since the mode is shifted to the stock mode in which the disc is stored in the designated area corresponding to the keys 103 to 106 or the α key 107, it is possible to shift to various function modes even while the disc is playing, which is extremely difficult for the user. Easy to use.

According to the MD device in the first embodiment, there are two operation modes for each function mode, for example, the single stock mode and the all stock mode in the stock mode of step S24 shown in FIG. For the eject mode of S20, the single eject mode and the all-eject mode are set, and for the play mode of step S22, the single play mode and the all-play mode are set. I need to put it.

Therefore, in the play mode of step S22 shown in FIG. 4, the all play mode is set in advance, and in the eject mode of step S20, the No. No. pressed in step S13 is set. Keys 103-106
Alternatively, if the α key 107 is pressed for a long time, the mode is changed to the single eject mode, and if it is pressed for a longer time than that, the mode is changed to the all eject mode. The No. related to the empty designated area pressed in S13. If the keys 103 to 106 or the α key 107 are pressed for a short time, the single stock mode is entered, and if the key is pressed for a long time, the all stock mode is entered.

If the designated disc exists in the device, it is determined whether the disc in the carrier 5 is the same as the designated disc (step S217). If the disc in the carrier 5 and the designated disc are not the same, the disc in the carrier 5 is stored in the original storage portion (step S218), and the designated next performance disc is stored in the carrier 5. 19 (step S219), and FIG.
The process moves to P10 shown in.

If the designated disk and the disk held in the carrier 5 are the same in step S217, the process shifts to P10 shown in FIG.

At P11 in the figure, the disk N of # 1
o. The disk to be stored in the storage section 50a corresponding to is designated as the next performance disk to be played next (step S220), and the process proceeds to step S216. Also,
If there is no previous performance disc in step S211, the process proceeds to step S220.

If it is determined in step S212 that the previous performance disk is to be stored in the # 1 storage section 50a, the # 2 disc No. 50b corresponding to
The disk to be stored in is designated as the next performance disk (step S221), and the process proceeds to step S216.

If the previous performance disk is the disk to be stored in the # 2 storage section 50b in step S213, the # 3 disk No. 50c corresponding to
The disk to be stored in is designated as the next performance disk (step S222), and the process proceeds to step S216.

If there is no disk designated as the next performance disk in the device in step S216, the corresponding disk No. Is incremented, that is, in the order of # 1 → # 2 → # 3 → # 4 → # 1 ... Or vice versa, and the incremented disk No. The disk to be stored in the storage section corresponding to is designated as the next performance disk (step S2
23) and the process moves to step S216.

According to the automatic disc selection processing according to the predetermined order, the discs in the apparatus are automatically selected in the predetermined order and sequentially played, so that the user's trouble of disc selection can be greatly saved. it can.

Next, the automatic disk selection processing by random selection will be described with reference to FIG. FIG. 21 is a flowchart showing the processing operation of the CPU 217 in the automatic disk selection processing. The automatic disk selection process (P12 in FIG. 21) is performed in step S shown in FIG.
It starts at 191 when the first timer times out.

At P12 shown in FIG. 21, it is determined whether or not the disc that was played immediately before in the play mode, that is, the previously played disc is in the device (step S231). If there is a previous performance disk in the device, each of the storage units 70a to 7a-7 based on the disk data held in the internal memory unit of the CPU 217 or the external memory unit connected to the CPU 217.
Based on the code sequence of the linear m-series feedback connection method (the selected disc No. is rearranged in a predetermined procedure without duplication) by selecting a disc to be stored in 0d. The disc next to the previous performance disc is designated as the next performance disc (step S23).
2) It is determined whether the disc in the carrier 5 is the designated next performance disc (step S2).
33).

If the disk in the carrier 5 is not the next performance disk, the disk in the carrier 5 is stored in the original storage section (step S234), and the next performance disk is stored in the storage sections 70a to 70d of the stocker 7 as the carrier. 5 is held (step S235), and the process proceeds to P10 shown in FIG.

If there is no previous performance disc in the device in step S231, a disc existing in the device is randomly selected based on the disc data held in the memory section, and the disc is randomly selected. Designate the disc as the next performance disc (step S2
36) and the process moves to step S233.

If the disc in the carrier 5 is the next performance disc in step S233, the process goes to P10 shown in FIG.

According to the automatic disc selection processing by the random selection, a disc is selected from all the discs housed in the device based on the code sequence of the linear m-series feedback connection method, and the disc is played. The time and effort required for the user to select a disc can be greatly reduced, and the user can enjoy a variety of disc reproductions. According to the automatic disk selection process, the disks are selected without duplication by using the linear m-sequence feedback connection method. However, by selecting the disks with random numbers, the duplication selection of the disks is performed. You may allow it.

In the MD device of the second embodiment, there are two operation modes for each function mode, for example, all eject mode and single eject mode for eject mode, all stock mode and single stock for stock mode. The mode must be set in advance to one of the operation modes for each function mode.
