[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device suitable for application to, for example, selecting and reproducing an arbitrary one from a plurality of compact disks.

[0002]

2. Description of the Related Art Among disk devices, for example, there is a disk device in which a plurality of compact disks (CDs) are separately loaded at the same time and an arbitrary CD is selectively reproduced (referred to as a CD autochanger).

FIG. 28 is a plan view showing an example of such a case. Reference numeral 1 denotes a tray, which is arranged so as to be able to be pulled out from a cabinet (not shown). The tray 1 has a rotating shaft 1a protruding from the center thereof. Reference numeral 2 denotes a tray, on which a circular mounting surface 3 for mounting a CD is recessed. The mounting surface 3 is formed at three places with a predetermined distance C and a predetermined angular interval from the center of the tray 2. A groove 4 is formed in the mounting surface 3 toward its center point.

On the tray 2, the mounting number “1” of the mounting surface 3
To “3” are given along a line passing through the centers of the tray 2 and the mounting surface 3. Then, the mounting number displayed on the drawing direction side (front side) of the tray 1 is displayed along the drawing direction, so that the user can recognize which mounting surface 3 the CD is mounted on. When the tray 1 is pulled out of the cabinet, only one mounting surface (the mounting surface of the mounting number “3” in FIG. 28) 3 is opened from the cabinet.

At the center of the tray 2, a hole 5 is provided. Then, the rotating shaft 1a of the tray 1 and the hole 5 of the tray 2 are fitted and fixed, and the tray 2 is rotatably disposed. Reference numeral 6 denotes an optical pickup, which is slidably (movable in the front-rear direction in FIG. 28) on a chassis (not shown). Reference numeral 7 denotes a disk crumb, which is arranged to be vertically movable. In addition, a display device (not shown) for displaying a placement number, a music selection number, and the like is provided at an appropriate position on a front panel (not shown).

When a CD selection operation is performed, the tray 2 rotates, and an arbitrary mounting surface 3 is disposed at a predetermined reproduction position (a position corresponding to the disk crumb 7). In this state, the placement number of the placement surface 3 at the reproduction position (the placement number “1” in FIG. 28) is displayed on the display device on the front panel. )
Subsequently, the disk clamper 7 is lifted to lift the CD from the mounting surface 3, and the disk is chucked.
Then, a motor (not shown) connected to the disk crumber 7 rotates, and the optical pickup 6 slides (moves forward in FIG. 28) to perform reproduction.

[0007]

In the disk device of the example shown in FIG. 28, only the placement number of the placement surface 3 at the reproduction position is displayed on a display device (not shown). For this reason, in order to check whether the CD is placed on any of the placing surfaces 3, the tray 1 is pulled out from a cabinet (not shown) and the placing number of the tray 2 is checked. Therefore, it is inconvenient to check on which mounting surface 3 a CD is mounted.

Accordingly, an object of the present invention is to make it easy to visually recognize the position of a disk placed on a tray having a plurality of loading surfaces.

[0009]

In this invention, a plurality of mounting surfaces for mounting disks are formed, and identification signs for identifying the plurality of mounting surfaces are respectively attached to the mounting surfaces. In a disk device having a tray and rotating the tray to select and reproduce any one of a plurality of disks, a first detection for detecting whether or not a disk is mounted on the mounting surface of the tray Means, second detection means for detecting a position state of the tray mounting surface, control means to which detection signals of the first detection means and the second detection means are supplied, a plurality of segments or a plurality of dots And the shape formed by the display element substantially corresponds to the arrangement shape of the mounting surface of the tray, and the mounting surface on which the disk is mounted by the detection signal of the first detecting means. Show only identification of Both as substantially corresponding with the position state of the tray of the mounting face by the detection signal of the second detection means is obtained by the so controlled by the control means to display by the display device.

[0010]

The display by the display element is displayed on the mounting surface of the tray.
The identification display of the tray 95 is made to correspond substantially to the placement numbers “1” to “3” in association with the position states of 7 to 99. Then, the disc is placed on the mounting surface 97-9 of the tray 95.
9 is detected by detecting means, for example, the optical pickup 57 or the like. Based on the detection signal from the detection means 57 and the like, only the identification display of the mounting surface on which the disk is mounted is displayed. Therefore, since only the identification display of the mounting surface on which the disk is mounted is displayed, it is possible to easily visually recognize on which of the mounting surfaces 97 to 99 the disk is mounted.

[0011]

An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a plan view of the disk device with the tray 70 pulled out. FIG. 1 shows a plane with a ceiling plate and the like (not shown) removed.

The segments D to 9F are controlled by the microcomputer 152152 so that the segments corresponding to the placement numbers “1” to “3” of the CD tray 95 are turned on.

As shown in FIG. 10, the outer frame 9G is arranged in a rounded triangular shape having substantially the same shape as the outer shape of the CD tray 95. The outer frame 9G includes segments a1 to a9, b4 to b7, c1, and c7 that form a part of the number frames 9A to 9C.
c9 and six segments g1 to g6.

In the disc apparatus of this embodiment, when the open / close button 66 is pressed, the tray 70 is pulled out to a predetermined position (the position shown in FIG. 1) by a driving mechanism such as the motor 17 and the gear 24. In the pulled-out state, two mounting surfaces (the mounting surfaces 97 and 99 in FIG. 1) of the mounting surfaces 97 to 99 of the CD tray 95 are opened. In this case, the placement numbers (the placement numbers “1” and “3” in FIG. 1)
Appear straight along the direction in which the tray 70 is pulled out.
In this state, it is possible to exchange a CD with the opened mounting surface.

The change button 68 (68) on the front panel 65
a to 68e) are pressed to select an arbitrary CD. Then, the tray 70 is stored in the cabinet 10 as shown in FIG. At the same time, the CD tray 95 is placed at a predetermined reproduction position (in FIG.
(A position corresponding to).

Here, the operation when the open / close buttons 66 and 67 are pressed in the play state or the stop state and the subsequent operation procedure will be described with reference to FIGS. 7 and 8.

First, the case where the open / close button 66 is pressed in the play state will be described. The operation in this case and the subsequent operation procedure proceed as in the prior art, as shown in FIG. That is, when the open / close button 66 is pressed (step 120), the rotation of the disk support 56 stops and the rotation of the CD stops (step 121). After the support 54 for supporting the CD is lowered to release the chucking (step 122), the tray 7
0 is pulled out of the cabinet 10. That is, CD
The tray 70 is pulled out while the tray 95 rotates 2/3 clockwise (step 123).

In this pulled-out state, a CD can be mounted, that is, newly loaded, or a replacement operation can be performed (step 124). Next, with the player pulled out, the play button 6
When the user presses 9a (step 125), the tray 70 is stored while the CD tray 95 rotates 1/3 clockwise (step 126). After the tray 70 is stored, the support 54 rises and the chucking state (step 12).
7) and play is started (step 128).

After the CD is loaded, the change button 68a
In the case where the user presses .about.68e (step 129),
The CD tray 95 plays the selected CD at the playback position (placement surfaces 97 to 9).
The tray 70 is stored while rotating to the position corresponding to the disk support 56 (step 130). Thereafter, as described above, after the support 54 is raised (step 127), the play is started (step 128).

When the open / close button 66 is pressed after the CD is loaded (step 131), the support 54 is raised after the tray 70 is stored (step 132), as in the case where the play button 69a is pressed. Then, a chucking state is set (step 133). When the play button 69a is pressed in this state (step 134),
Play is started (step 128).

When the open / close button 66 is pressed in the stop state, the same operations as described above are performed except for step 121. When the tray 70 is opened and closed, C
The reason why the D tray 95 is rotated is in consideration of convenience in reproduction.

Next, as shown in FIG.
The case of pressing is described. Open / close button 67
Is pressed (step 135), the microcomputer 152 determines whether or not it is in the play state (step 136). If it is determined that the player is not in the play state, the operation instruction of the open / close button 67 is not received (step 137), and the tray 70 is set in the cabinet 10
(Step 138). That is, even if the open / close button 67 is pressed in the stop state, the tray 70
Is not withdrawn.

If it is determined that the player is in the play state, an operation instruction of the open / close button 67 is accepted (step 139), and C
In the state where the D tray 95 does not rotate, that is, the position of the mounting surfaces 97 to 99 of the CD tray 95 is maintained, the tray 7
0 is derived (step 140). In this case, the mounting surfaces 97 to 99 are released from the cabinet 10 because:
As shown in FIG. 1, there are two mounting surfaces 98 and 99 other than the mounting surface 97 corresponding to the disk support 56. Therefore, in a state where the mounting surfaces 98 and 99 are opened, other CDs can be mounted on the mounting surface 97 other than the mounting surface 97 corresponding to the CD being reproduced (step 141).

When the open / close button 67 is pressed again after mounting another CD (step 142), the tray 70 is stored (step 143).

When the open / close button 66 is pressed (step 144), the tray 70 is stored. That is, if the tray 70 is pulled out regardless of the stop state or the play state, the tray 70 can be stored by subsequently pressing the open / close button 66. As a modification, the open / close button 66
Is pressed once (step 144), the CD tray 95 is stored once, the play state is changed to the stop state, and the chucking state is released.
May be drawn.

After the reproduction of the CD being reproduced is completed, the player immediately enters the play state by selecting and operating another newly inserted CD. Therefore, other CDs can be reproduced quickly and smoothly. Even if the change buttons 68a to 68e are pressed after mounting another CD, the tray 70 is not stored.

Next, the display state of the display element 9 of the display device 8 will be described. When the power of the disk device is turned on in a state where no CD is mounted on any of the mounting surfaces 97 to 99, as shown in FIG. 10, all the segments of the display element 9 are turned off.

On the other hand, when the power of the disk device is turned on while the CD is mounted on the mounting surfaces 97 to 99, the mounting numbers “1” to “3” of the mounting surfaces 97 to 99 of the CD tray 95 are set. The predetermined segments of the number sections 9D to 9F of the display element 9 are turned on so as to correspond to. More specifically, for example, as shown in FIG.
The display is made by lighting the segments f2 and f3 of F. When making it correspond to the placement number "2", all segments except the segment d3 of the number section 9D are displayed by lighting. When making it correspond to the placement number "3", all segments except the segment e5 of the number section 9E are displayed by lighting.

FIGS. 11 and 12 show all the mounting surfaces 97 to 97.
FIG. 11 shows a state where a CD is placed at 99, and FIG.
FIG. 12 is a diagram showing the position of the D tray 95, and FIG. 12 is a diagram showing the position of the CD tray 95 in FIG.

The position of the CD tray 95 is C
The detection is performed by the detection pieces 104 to 106 of the D tray 95 passing between the light emitting element 88 and the light receiving element 89 which are sensors. Whether the CD is placed on the placement surfaces 97 to 99 is detected by the optical pickup 57 when the placed CD is located at the reproduction position. These detection signals are supplied to the microcomputer 152 as shown in FIG. 23, and the control signals of the microcomputer 152 turn on the segments of the number sections 9D to 9E.

In the case of this example, the optical pickup 5
7 is used to detect the mounting state of the CD.
After one rotation of the CD tray 95, the presence or absence of a CD is detected. Further, a detecting means for detecting whether or not a CD is mounted may be provided corresponding to each mounting surface. In this case, the presence or absence of the CD mounting surface can be detected at the same time.

Therefore, the display device 8 of the disk device of this embodiment
, Predetermined segments of the number portions 9D to 9F corresponding to the mounting numbers “1” to “3” of the mounting surfaces 97 to 99 on which no CD is mounted do not light. That is, the CD tray 9 in FIG.
In the state of position 5, when no CD is placed on the placing surface 97, the segments d1 to d6 of the number section 9D do not light up as shown in FIG.

Similarly, the mounting surfaces 97 and 98 have C
When D is not placed, as shown in FIG.
The segments d1 to d6 of the number section 9D and the segments e1 to e6 of the number section 9E do not light. Further, when no CD is placed on all the placement surfaces 97 to 99,
As shown in FIG. 10, the segment d1 of the number parts 9D to 9F
To d6, e1 to e6, and f1 to f6 do not light.

According to the present embodiment, the mounting numbers “1” to “0” where the CD is mounted on the mounting surfaces 97 to 99 of the CD tray 95
Since the segments of the number portions 9D to 9E of the display element 9 corresponding to only “3” are turned on, any of the mounting surfaces 97 to 9
9 can be easily visually recognized as to whether or not a CD is placed.

When the CD at the playback position is chucked and enters the play state, as shown in FIG. 15, an appropriate number of playback position number frames (only 9A in this example) (in this example). (Three) segments a1 to a9 blink sequentially. FIG. 15 is a diagram showing a case where the CD on the mounting surface 97 is in the play state in the position state of the CD tray 95 in FIG. In addition, the segments a1 to a of the number frame 9A
Of the nine, the number of simultaneously blinking can be arbitrarily set.

In this example, the segments a2 to a4 of the number frame 9A are turned on first, as shown in FIG. Next, as shown in FIG.
Segments a5 to a7 are turned on at the same time as 2 to a4 are turned off. Finally, as shown in FIG.
The segments a8 to a1 are turned on at the same time as the segments 5 to a7 are turned off. This blinking is repeated sequentially during the reproduction period.
The other number frames 9B and 9C do not blink.

In this example, when the play button 69a is pressed, the disc support 59 rotates. Then, the presence or absence of rotation of the disk support 59 is detected, and this detection signal is supplied to the microcomputer 152 (see FIG. 24). Further, as described above, since the rotation position of the CD tray 95 is detected by the sensors 88 and 89, the mounting surface at the reproduction position is detected. Then, the detection signal is supplied to the microcomputer 152, and under the control of the microcomputer 152, the segments a1 to a9 of the number frame 9A of the display element 9 blink sequentially. When the rotation of the disk support 59 stops, the detection signal is supplied to the microcomputer 152, and the segments a1 to a9 of the number frame 9A of the display element 9 are turned off under the control of the microcomputer 152.

According to this example, the segment a1 of the number frame 9A corresponding to the placement numbers “1” to “3” during the CD performance
To a9 are sequentially and periodically controlled to blink at a predetermined cycle, and the display of the segments a1 to a9 blinks as if the CD is rotating as a whole. Can be easily visually recognized. Further, according to this example, the segments a1 to a9 of the number frame 9A during the CD performance are blinked sequentially,
Since the segments d1 to d6 of the number section 9D are turned on so as to correspond to the placement numbers "1" to "3" at the playback position, the CD placed on any of the placement surfaces 97 to 99 can be played. Can be easily visually recognized.

When the CD at the playback position is chucked and put into the play state, the appropriate number of number portions 9D corresponding to the placement numbers "1" to "3" at the playback position (in this example, (2) segments d1 to d6 may be blinked sequentially. Hereinafter, description will be made with reference to FIG. In the example of FIG. 16, the CD tray 95 corresponds to the position shown in FIG. The control of the number section 9D is performed by control as shown in FIG.
