[0001]

[Industrial applications]

 The present invention relates to a disc device suitable for application to, for example, selecting and reproducing any one of a plurality of compact discs.

[0002]

[Prior Art]

 2. Description of the Related Art Some disk devices include, for example, a CD autochanger in which a plurality of compact disks (CDs) are simultaneously placed separately and an arbitrary CD is selectively played.

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

The tray 2 is provided with placement numbers “1” to “3” of the placement surface 3 along a line passing through the centers of the tray 2 and the placement surface 3. The loading number displayed on the pull-out direction side (front side) of the tray 1 is displayed along the pulling-out direction, so that the user can recognize on which loading surface 3 the CD is loaded. When the tray 1 is pulled out from the cabinet, only one placement surface (the placement surface with the placement number “3” in FIG. 28) 3 is opened from the cabinet.

A hole 5 is provided at the center of the tray 2. 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 arranged. Reference numeral 6 denotes an optical pickup, which is slidably (movable in the front-back direction in FIG. 28) on a chassis (not shown). Reference numeral 7 is a disc crumb, which is arranged so as to be movable up and down. In addition, a display device (not shown) for displaying a mounting number, a music selection number, etc. is appropriately arranged on the front panel (not shown).

When a CD selecting operation is performed, the tray 2 is rotated so that an arbitrary mounting surface 3 is placed at a predetermined reproducing position (a position corresponding to the disc clamper 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 of the front panel. ) Subsequently, the disc clamper 7 rises to lift the CD from the mounting surface 3, and the disc is chucked. Then, a motor (not shown) connected to the disc clamper 7 rotates and the optical pickup 6 slides (moves forward in FIG. 28) to perform reproduction.

[0007]

[Problems to be solved by the device]

 In the disc device of the example of FIG. 28, the mounting number of the mounting surface 3 at the reproduction position is only displayed on the display device (not shown). Therefore, when the operation of rotating the tray 2 in the tray 1 is performed, it is difficult to confirm whether or not the tray 2 is actually rotating.

Therefore, an object of the present invention is to make it possible to easily and visually recognize the rotating state of a tray having a plurality of mounting surfaces.

[0009]

[Means for Solving the Problems]

 According to the present invention, in a disc device for selectively reproducing, for example, any one of a plurality of discs, a first tray and a loading device for rotatably mounting the disc on the first tray. A second tray having a plurality of mounting surfaces, a detection unit for detecting the presence or absence of rotation of the second tray, a rotation state of the second tray, and the like are displayed and are composed of a plurality of segments or a plurality of dots. A display element is provided so that the display by the display element substantially corresponds to the outer shape of the second tray, and the outer shape of the second tray when the second tray is rotated based on the detection signal of the detection means. Is displayed corresponding to the rotation of the second tray.

[0010]

[Action]

 The display by the display element 9 is made to substantially correspond to the outer shape of the second tray 95. Then, the second tray 95 is rotated. Then, the sensors 88 and 89, which are detecting means, detect the rotation of the second tray 95. Based on the detection signals of the detection means 88 and 89, the display of the outer shape of the second tray 95 is made to correspond to the rotation of the second tray 95. Therefore, it is possible to easily visually recognize that the second tray 95 is rotating.

[0011]

【Example】

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

First, the overall configuration of the disk device will be described with reference to FIG. 10 is a cabinet, 70 is a tray, and 95 is a CD tray. The cabinet 10 is configured so that the tray 70 can be pulled out. The tray 70 is a rotatable CD tray 95.

The cabinet 10 is provided with a drive mechanism such as a motor 17 for pulling out the tray 70, gears 24, 31, 32, and the like. Further, the cabinet 10 is provided with a chucking member 53 for chucking a compact disc (CD), a support 54, a chucking mechanism such as a disc support 56, and the like.

An optical pickup 57 is slidable in the front-rear direction on a holder 54 arranged in the center of the rear side of the cabinet 10. Further, the support body 54 is tiltably arranged with respect to the cabinet 10. Then, the support 54 is tilted by the rotation of the gear 24 and the cam 35.

The reason why the chucking mechanism is arranged on the opposite side (rear side) to the pulling-out direction of the tray 70 is to prevent the chucking mechanism from hindering the pulling-out of the tray 70. The stopper 42 locks the cam 35 at a predetermined position.

Rails 61 are integrally formed at the left and right ends of the cabinet 10. The rail 61 guides the movement of the tray 70 in the slide (front-back) direction. 63 is a stopper, and the stopper 63 is formed integrally with the cabinet 10.

As shown in FIG. 1, the stopper 63 is formed in the vicinity of the rail 61 and prevents the tray 70 from being pulled out from the cabinet 10. The stopper 63 is formed at a position where the tray 70 is pulled out until the two mounting surfaces 97 to 99 of the CD tray 95 can be exposed.

A switch 64 detects the position of the tray 70. As shown in FIG. 1, the switch 64 is arranged on the rear side of the cabinet 10 and detects that the tray 70 is stored in the cabinet 10.

The tray 70 is provided with a motor 71 for rotating the CD tray 95 and a drive mechanism (not shown). In addition, the tray 70 is formed with a wall portion 84 having linear portions 84a to 84e and curved surface portions 84f to 84i in a substantially elliptical shape. A groove 85 and a lane surface 86 are formed on the tray 70. Since the center P 1 of the CD tray 95 is eccentrically rotated with respect to the projection 82 arranged at the center of the lane surface 86, the CD 95 is rotated while being eccentric along the wall portion 84.

Further, a notch 87 is formed in the tray 70 at the center on the rear side thereof, that is, at a portion facing the disc support 56 and the optical pickup 57. This notch 87 is formed to allow the tray 70 to escape from the disk support 56 or the like in the CD chucking state. As a result, the tray 70 can be pulled out from the cabinet 10 while the CD is being chucked.

On the tray 70, a light emitting element 88 and a light receiving element 89, which are sensors, are arranged facing each other at portions corresponding to detectors 104 to 106 of a CD tray 95 described later (see FIGS. 5 and 6). .. The sensors 88 and 89 detect the positional states of the mounting surfaces 97 to 99 of the CD tray 95 described later.

As shown in FIGS. 1 to 4, the CD tray 95 has an arc-shaped triangular shape with three sides, and the CD is placed on the upper surface thereof at a predetermined angular interval (120 degrees in this example). The mounting surfaces 97 to 99 are recessed at three places.

Further, the CD tray 95 has a notch 100 formed from the outer periphery thereof toward the center of the CD tray 95 on the same line as the centers of the mounting surfaces 97 to 99. The notch 100 is formed up to the vicinity of the center of the mounting surfaces 97 to 99. The notch 100 is formed from the outer periphery of the CD tray 95 toward the center of the mounting surfaces 97 to 99 when the CD tray 95 is pulled out when the tray 70 is pulled out in the chucking state. This is to prevent collision with the pickup 57. The notch 100 is for allowing the CD to face the disc support 56 and the optical pickup 57.

In the CD tray 95, the gear portion 102 as shown by the broken lines in FIGS. 1 and 2 is formed inside the notch 100. The gear portion 102 has an internal tooth shape and meshes with a gear (not shown) arranged on the tray 70.

The CD tray 95 is formed with a recess 101 from the outer periphery thereof toward the outer periphery of the mounting surfaces 97 to 99. The recess 101 is formed at two places sandwiching the notch 100 with respect to one placement surface 97 to 99. The recess 101 is set to be slightly lower than the mounting surfaces 97 to 99. The recess 101 is a portion that allows the CD to be easily removed from the mounting surfaces 97 to 99. In other words, the concave portion 101 provides a space such as a fingertip on the lower surface of the CD.

As shown by the broken line in FIG. 2, the CD tray 95 has arc-shaped contact pieces 103 near the outer periphery of the back surface thereof, and detection pieces 104 to 106 at three locations inside the contact pieces 103. It is formed. The tip of the contact piece 103 contacts the lane surface 86 of the tray 70 to smoothen the rotation of the CD tray 95. The tips of the detection pieces 104 to 106 move in the groove 85 of the tray 70.

In the state of FIG. 2, the detection piece 104 for detecting the first mounting surface 97 is arranged on the front side, and the detection piece 104 for detecting the second mounting surface 98 is arranged on the left side. 105 and a detection piece 106 for detecting the third mounting surface 99 are arranged on the right side. As shown in FIG. 2, the CD tray 95 is provided with protrusions 97a to 99a, which are set slightly higher than the mounting surfaces 97 to 99, on the outer peripheral portion between the notch 100 and the recess 101, respectively. It The protrusions 97a to 99a are for restricting the movement of the CD9.

As described above, since the CD tray 95 rotates while being eccentric, the loci of the detection pieces 104 to 106 do not form a perfect circle with respect to the center (protrusion 82) of the tray 70. That is, the loci of the detection pieces 104 to 106 are partially curved as shown in FIG. 5, and the width between the loci is expanded. FIG. 5 is an intermittent drawing of the locus of the detection piece 106 of the CD tray 95 moving on the groove 85 of the tray 70. Although FIG. 5 shows only the locus of the detection piece 106, the other detection pieces 104 and 105 also draw the same locus.

Therefore, in this example, the light emitting element 88 and the light receiving element for detecting the rotational position of the CD tray 95, that is, the reproducing position of the mounting surfaces 97 to 99, are located at the portion corresponding to the narrow intersection T between the trajectories. Place 89. The detection pieces 104 to 106 pass through four intersections T, but the light emitting element 88 and the light receiving element 89 are arranged at one intersection T.

FIG. 6 is a diagram showing a detected state of the reproduction position of the CD tray 95. Further, FIG. 6 is a diagram in which the mounting surface 99 is arranged at a reproducing position, that is, a position facing the disc support 56. Then, when the detection piece 106 for the mounting surface 99 passes between the light emitting element 88 and the light receiving element 89, it is detected that the mounting surface 99 is located at the reproduction position. It should be noted that the other detection pieces 104 and 105 pass between the light emitting element 88 and the light receiving element 89 to detect that the mounting surfaces 97 and 98 are located at the reproducing position.

As shown in FIGS. 1 and 2, the CD tray 95 is provided with mounting numbers “1” to “3” of the mounting faces 97 to 99 between the mounting faces 97 to 99 near the outer circumference. It That is, the placement number “1” is placed on the first placement surface 97, the placement number “2” is placed on the second placement surface 98, and the placement number “2” is placed on the third placement surface 99. The number "3" is attached respectively. In addition, the placement numbers “1” to “3” are provided near the recesses 101 on both sides of the placement surfaces 97 to 99, respectively.

The placement numbers “1” to “3” are given toward the center side of the CD tray 95. That is, when the tray 70 is pulled out from the cabinet 10, the placement numbers “1” to “3” corresponding to the placement surface opened from the cabinet 10 are attached so as to extend in the pull-out direction of the tray 70. For example, as shown in FIG. 1, when the mounting surfaces 97 and 99 are opened from the cabinet, the mounting numbers “1” and “3” are arranged in parallel.

The front panel 65 as shown in FIG. 3 is attached to a cabinet body (not shown). In addition, in the disc device of this example, the tray 70 can be pulled out in the stopped state, and also the tray 70 can be pulled out even in the chucking state of the CD, that is, the playing state. Therefore, in this example, as shown in FIG. 3, two opening / closing buttons 66 and 67 of the tray 70 are arranged on the right side of the upper end of the front panel 65. The open / close button 66 is for pulling out the tray 70 in the stopped state. The open / close button 67 is for pulling out the tray 70 in the play state.

Further, on the front panel 65, three change buttons 68a to 68c are arranged in the center of the upper end thereof, and two change buttons 68d and 68e are arranged substantially in the center of the right side of the front panel 65, respectively. The change buttons 68a to 68c can directly select the placing surfaces 97 to 99, and the change buttons 68d and 68e rotate the CD tray 95 by 1/3 in the forward and reverse directions to place the placing surfaces 97 to 99. Is to move. Further, 69a is a play button, and 69b is a stop button.

Further, on the front panel 65, as shown in FIG. 3, the display device 8 is arranged in the lower center of the outlet 65a. A part of the tray 70 projects from the outlet 65a of the front panel 65 (the front side projects from the broken line in FIG. 1).

As shown in FIG. 9, the display device 8 is provided with a fluorescent display tube using a display element 9 composed of a plurality of segments. Then, by controlling blinking of an appropriate segment of the display element 9, the position state of the CD tray 95, the playing state of the CD, etc. are displayed. Although FIG. 9 shows only the display element 9, a display element (not shown) for displaying the time, music number, etc. is also arranged at an appropriate portion of the display device 8.

Detection signals from the detection pieces 104 to 106, the light emitting element 88, the light receiving element 89 and the detection means 151 of the optical pickup 57 are supplied to a microcomputer 152 (microcomputer) 152 as shown in FIG. Then, a control signal from the microcomputer 152152 is supplied to the display device 8 to control the lighting of the segment of the display element 9.

As shown in FIG. 10, the display element 9 uses 51 segments. The segment of the display element 9 is formed by connecting the number parts 9D to 9F arranged at three places, the number frames 9A to 9C surrounding these number parts 9D to 9F, and a part of these number frames 9A to 9C. It is composed of a frame 9G.

The number frames 9A to 9C are composed of nine segments a1 to a9, b1 to b9, and C1 to C9 in a circular shape. The number frames 9A to 9C are arranged so as to correspond to the position state of the CD tray 95, as shown in FIG. The circular shape of the number frames 9A to 9C corresponds to the shape of the mounting surfaces 97 to 99 of the CD tray 95.

By the way, as the usual number display, a "day" character is used. However, in the case of this example, the maximum number of CDs placed on the CD tray 95 is three. Therefore, as shown in FIG. 10, the number parts 9D to 9F for displaying the numbers are composed of nine segments d1 to d6, e1 to e6, and f1 to f6 in an inverted “9” shape. It should be noted that the segments of the number sections 9D to 9F are controlled by the microcomputer 152152 so as to light up corresponding to the mounting numbers "1" to "3" of the CD tray 95.

As shown in FIG. 10, the outer frame 9 G is arranged in the shape of a rounded corner triangle that is substantially the same as the outer shape of the CD tray 95. Further, the outer frame 9G is composed of segments a1 to a9, b4 to b7, c1, c7 to c9 and six segments g1 to g6 which constitute a part of the number frames 9A to 9C.

In the disk device of this example, 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 the drive mechanism such as the motor 17 and the gear 24. In this pulled-out state, of the mounting surfaces 97 to 99 of the CD tray 95, two mounting surfaces (the mounting surfaces 97 and 99 in FIG. 1) 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. Then, in this state, the CD can be exchanged with respect to the opened mounting surface.

The change button 68 (68a to 68e) on the front panel 65 is pressed to select an arbitrary CD. Then, the tray 70 is housed in the cabinet 10 as shown in FIG. At the same time, the CD tray 95 is rotated to a predetermined reproducing position (the mounting surface 97 in FIG. 4 corresponds to the disc support 56) to enter the play state.

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

First, a 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 conventional case, as shown in FIG. That is, when the open / close button 66 is pressed (step 120), the rotation of the disc support 56 is stopped and the rotation of the CD is stopped (step 121). Then, after the support 54 for supporting the CD descends and the chucking is released (step 122), the tray 70 is pulled out from the cabinet 10. That is, the tray 70 is pulled out while the CD tray 95 rotates clockwise by 2/3 (step 123).

In this pulled-out state, the CD can be mounted, that is, newly mounted, or the replacement operation can be performed (step 124). Next, when the play button 69a is pressed in the pulled-out state (step 125), the tray 70 is stored while the CD tray 95 rotates clockwise by 1/3 (step 126). After the tray 70 is housed, the support 54 rises to enter the chucking state (step 127) and the play is started (step 128).

When the change buttons 68 a to 68 e are pressed after the CD is mounted (step 129), the CD tray 95 plays the selected CD (the mounting surfaces 97 to 99 correspond to the disc support 56). The tray 70 is stored while rotating to () (step 130). After that, similarly to the above, after the support 54 is lifted (step 127), the play is started (step 128).

Further, when the open / close button 66 is pressed after the CD is loaded (step 131), the support 54 is moved after the tray 70 is stored (step 132), as in the case where the play button 69 a is pressed. It rises to a chucking state (step 133). When the play button 69a is pressed in this state (step 134), the play is started (step 128).

When the open / close button 66 is pressed in the stop state, the same operation as described above is performed except for step 121. Further, the reason why the CD tray 95 is rotated when the tray 70 is opened and closed is for the convenience of reproduction.

Next, as shown in FIG. 8, a case of pressing the open / close button 67 will be described. When the open / close button 67 is pressed (step 135), the microcomputer 152 determines whether it is in the play state (step 136). When it is determined that the play state is not established, the operation instruction of the open / close button 67 is not accepted (step 137), and the tray 70 is not pulled out from 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 pulled out.

When it is determined that the CD is in the play state, the operation instruction of the open / close button 67 is received (step 139) and the state in which the CD tray 95 is not rotated, that is, the mounting surfaces 97 to 99 of the CD tray 95 are maintained. The tray 70 is pulled out in this state (step 140). In this case, the mounting surfaces 97 to 99 are released from the cabinet 10 because two mounting surfaces 98 other than the mounting surface 97 corresponding to the disk support 56 are provided, as shown in FIG. 99. Therefore, with the loading surfaces 98 and 99 opened, another CD can be loaded in addition to the loading 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).

Also, when the open / close button 66 is pressed (step 144), the tray 70 is stored. In other words, regardless of the stop state or the play state, if the tray 70 is pulled out, the tray 70 can be stored by pressing the open / close button 66 thereafter. As a modified example, by pressing the open / close button 66 (step 144), the CD tray 95 is once housed, the play state is stopped, the chucking state is released, and then the CD tray 95 is pulled out again. It may be configured as follows.

Then, after the reproduction of the CD being reproduced is finished, a play state is immediately set by selecting another newly mounted CD. Therefore, other CDs can be played back 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. As shown in FIG. 10, all the segments of the display element 9 are turned off even when the power of the disk device is turned on in the state where the CD is not mounted on any of the mounting surfaces 97 to 99.

On the other hand, when the power of the disc device is turned on with the CD placed on the mounting surfaces 97 to 99, the mounting numbers "1" to "3" on the mounting surfaces 97 to 99 of the CD tray 95 are set. A predetermined segment of the number parts 9D to 9F of the display element 9 is lit so as to correspond to. Specifically, for example, as shown in FIG. 11, when the placement number is “1”, the segments f2 and f3 of the number portion 9F are displayed by lighting. In the case where the placement number "2" is associated, the display is performed by turning on all the segments except the segment d3 of the number portion 9D. In the case of corresponding to the placement number “3”, all the segments except the segment e5 of the number part 9E are displayed by lighting.

11 and 12 show a state in which the CDs are placed on all the placing surfaces 97 to 99. FIG. 11 shows the position state of the CD tray 95 in FIG. 1, and FIG. 12 shows the CD tray in FIG. It is a figure which shows the position state of 95.

Then, the position state of the CD tray 95 is detected by the detection pieces 104 to 106 of the CD tray 95 passing between the light emitting element 88 and the light receiving element 89 which are sensors. Further, whether or not the CD is placed on the placing surfaces 97 to 99 is detected by the optical pickup 57 when the placed CD is located at the reproduction position. Then, 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, since the optical pickup 57 is configured to detect the mounted state of the CD, the presence or absence of the mounted CD is detected after the CD tray 95 is rotated once. .. Further, a detection means for detecting the presence / absence of a CD placed may be provided corresponding to each of the placement surfaces. In this case, the presence or absence of the CD mounting surface can be detected at the same time.

Therefore, in the display device 8 of the disk device of the present example, the predetermined numbers 9D to 9F corresponding to the mounting numbers “1” to “3” on the mounting surfaces 97 to 99 on which the CD is not mounted are predetermined. Segment does not light up. That is, in the position state of the CD tray 95 in FIG. 4, when the CD is not 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, when the CD is not placed on the placing surfaces 97 and 98, as shown in FIG. 14, the segments d1 to d6 of the number section 9D and the segments e1 to 9E of the number section 9E are shown. e6 does not light up. Further, when the CDs are not placed on all the placement surfaces 97 to 99, the segments d1 to d6, e1 to e6, and f1 to f6 of the number portions 9D to 9F do not light up as shown in FIG. ..

According to this example, the number parts 9D to 9E of the display element 9 corresponding to only the mounting numbers “1” to “3” on which the CDs are mounted on the mounting surfaces 97 to 99 of the CD tray 95. Since the segment is turned on, it can be easily visually recognized which of the mounting surfaces 97 to 99 the CD is mounted on.

Then, when the CD at the playback position is chucked into the play state, as shown in FIG. 15, an appropriate number of number frames (only 9A in this example) at the playback position (in this example, the number frame is set). (3) segments a1 to a9 sequentially blink. Note that FIG. 15 is a view 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. The number of the segments a1 to a9 of the number frame 9A that blink simultaneously can be set arbitrarily.

In this example, the segments a2 to a4 of the number frame 9A are turned on first, as shown in black in FIG. 15A, for example. Next, as shown in FIG. 15B, the segments a2 to a4 are turned off and at the same time, the segments a5 to a7 are turned on. Finally, as shown in FIG. 15C, the segments a5 to a7 are turned off and at the same time, the segments a8 to a1 are turned on. Then, during the reproduction period, this blinking is repeated successively. 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 micro computer 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 thereof, the segments a1 to a9 of the number frame 9A of the display element 9 sequentially blink. When the rotation of the disk support 59 is stopped, 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 segments a1 to a9 of the number frame 9A corresponding to the placement numbers “1” to “3” during the CD performance are cyclically and sequentially controlled in a predetermined cycle so that the whole is displayed. Since the display of the segments a1 to a9 blinks as if the CD is rotating, even if the volume is low, it is possible to easily visually recognize whether or not the performance is being performed. Further, according to this example, the segments a1 to a9 of the number frame 9A during CD playing are sequentially blinked, and the number portion 9D of the number portion 9D is adapted to correspond to the placement numbers "1" to "3" at the reproduction position. Since the segments d1 to d6 are lit, it is possible to easily visually recognize which of the mounting surfaces 97 to 99 is mounted on the CD.

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

In the example of FIG. 16, the segments d1 and d2 of the number part 9D are first turned on as shown in black in FIG. 16A, and then the segment d1 is turned on as shown in FIG. 16B. Is turned off, and at the same time, the segment d6 is turned on. Further, as shown in FIG. 16C, the segment d2 is turned off while the segment d6 is turned on, and at the same time, the segment d5 is turned on. Finally, as shown in FIG. 16D, the segment d6 is turned off while the segment d5 is turned on, and at the same time, the segment d4 is turned on. Then, during the reproduction period, this blinking is repeated successively. The other numbers 9E and 9F do not blink, and are turned on when the CD is mounted on the mounting surface, and are turned off when the CD is not mounted.

According to this example, since the segments d1 to d6 of the number part 9D corresponding to the placement numbers “1” to “3” during the CD performance are sequentially blinked in appropriate numbers, any placement surface 97 It is possible to visually and easily recognize whether or not the CDs placed in ~ 99 are being played.

Further, in the play state, the display color of the segments d1 to d6 of the number part 9D corresponding to the placement numbers “1” to “3” at the reproduction position is changed to the segment e1 of the other number parts 9E and 9F. The display colors of ~ e6 and f1 to f6 may be changed. For example, the display color of the 9D segments d1 to d6 of the number part in the playback position is set to be green in the stop state and red in the play state. The display colors of the segments e1 to e6 and f1 to f6 of the other number parts 9E and 9F are set to be green. The control of the display color of the number part 9D is the same as in the example of FIG.

For example, in the case of FIG. 11, the segments d1, d2 and d4 to d6 of the number part 9D are displayed in red, and the segments e1 to e4, e6 and f2 to f3 of the other number parts 9E and 9F are displayed in green. Is displayed. Also in the case of FIG. 12, similarly, the segments d2 and d3 of the number part 9D are displayed in red, and the segments of the other number parts 9E and 9F are displayed in green.

According to this example, the display colors of the segments d1 to d6 of the number part 9D corresponding to the placement numbers “1” to “3” being played on the CD are changed to the display colors of the other number parts 9E and 9F. Since it is displayed differently, it is possible to visually and easily recognize which of the mounting surfaces 97 to 99 the CD mounted is being played.

In the disk device capable of reproducing and recording, the display color of the segments d1 to d6 of the number part 9D during reproduction may be different from the display color during recording.

Subsequently, when the change buttons 68a to 68e are pressed to rotate the CD tray 95, an appropriate number (five in this example) of segments a1 to a4, b4 to b7, of the outer frame 9G of the display element 9 are displayed. The c7 to c1 and g1 to g6 are sequentially blinked as if the CD tray 95 is rotating at a predetermined cycle. Hereinafter, description will be made with reference to FIG. 17 as an example. FIG. 17 corresponds to the position state of the CD tray 95 of FIG.

In this example, when the change buttons 68a to 68e are pressed, for example, the CD tray 95 rotates in the clockwise direction. Then, this rotation is detected by the sensors 88 and 89 (see FIG. 25). Then, under the control of the microcomputer 152, the segments a1 to a4, b4 to b7, c7 to c1, and g1 to g6 of the outer frame 9G of the display element 9 are sequentially blinked.

As for the blinking of the segment of the outer frame 9G, as shown in FIG. 17A, first, the segments a1 to a4 and g1 are turned on, and then, as shown in FIG. 17B, when the segments a1 to a4 and g1 are turned off. At the same time, the segments g2 and b4 to b7 are turned on. Subsequently, as shown in FIG. 17C, the segments g2 and b4 to b7 are turned off, and at the same time, the segments g3, g4 and c7 to c9 are turned on. Finally, as shown in FIG. 17D, the segments g3, g4, and c7 to c9 are extinguished, and at the same time, the segments c1, g5, g6, a1, a2 are illuminated. Then, during the rotation of the CD tray 95, this blinking is repeated in the clockwise direction so as to correspond to the clockwise direction of the CD tray 95.

The blinking speed of the segment of the outer frame 9G may correspond to the rotation speed of the CD tray 95. In this case, the rotating state of the CD tray 95 can be easily visually recognized by blinking the segment of the outer frame 9G.

The rotation stop of the CD tray 95 is detected by the sensors 88 and 89, and is controlled by the microcomputer 152 based on the detection signal.

The numbers 9D to 9F in this example are displayed as follows. For example, while the CD tray 95 is rotating from the state shown in FIG. 11, the appropriate segments d1 to d6, e1 to e6 and f1 to f6 of the three numbered parts 9D to 9F are blinked at the same time. In this case, the segments of the number parts 9D to 9F corresponding to the placement numbers "1" to "3" before rotation are made to blink.

Then, when the rotation of the CD tray 95 is stopped, the display numbers are changed to those shown in FIG. 12, for example, corresponding to the placement numbers “1” to “3” of the placement surfaces 97 to 99 after the rotation. In this case, only the segments d1 to d6 of the number part 9D corresponding to the placement number at the reproduction position are made to blink, and only the segments e1 to e6 of the number parts 9E and 9F corresponding to other placement numbers are made to blink. , The segments e1 to e6 and f1 to f6 of the number parts 9E and 9F corresponding to other placement numbers are turned on.

Then, after it is confirmed by the microcomputer 152 that the CD is mounted on the mounting surfaces 97 to 99 at the reproduction position, the segments d1 to d6 of the number section 9D are turned on. The detection of the position state of the CD tray 95 and the mounting state of the CD are the same as those in FIG.

According to this example, an appropriate number of the segments a1 to a4, b4 to b7, c7 to c1 and g1 to g6 of the outer frame 9G are cyclically and sequentially blinked at a predetermined cycle to form a segment as a whole. Since the display blinks as if the CD tray 95 is rotating, it is possible to easily visually recognize that the CD tray 95 is rotating.

When the CD tray 95 rotates in the counterclockwise direction, the segment of the outer frame 9G blinks in the counterclockwise direction to correspond to this rotation. In this case, the rotation direction of the CD tray 95 can be easily visually recognized by blinking the segment of the outer frame 9G. Further, while the CD tray 95 is rotating, only some of the segments a1 to a4, b4 to b7, c7 to c9, c1 of the number frames 9A to 9C constituting the outer frame 9G are sequentially blinked. It may be displayed. In this case, the segments G1 to G6 of the outer frame 9G may be turned off or turned on.

FIG. 18 is a diagram showing another embodiment, and in this example, the rotation state of the CD tray 95 is such that the outer frame 9G is reversed. For example, a state in which the CD tray 95 shifts from the state of FIG. 1 to the state of FIG. 4 will be described. First, before rotation of the CD tray 95, as shown in FIG. 18A, appropriate segments of the numbered parts 9D to 9F are turned on, and the segments a1 to a4, b4 to b7, c7 ... which constitute the outer frame 9G. C1 and g1 to g6 are turned on.

Next, as shown in FIG. 18B, the segments are arranged so that the outer frame 9H has an inverted triangular shape. The outer frame 9H is formed in an inverted triangle in order to correspond to the arrangement of the CD tray 95 in the position shown in FIG. Then, while the CD tray 95 is rotating, all the segments of the outer frame 9H are blinked. The blinking of the outer frame 9H of the display element 9 is controlled by the microcomputer 152 as in the example of FIG. The segment of the outer frame 9H shown in FIG. 18B is configured so as not to abut the segment of the display element 9 of FIG. 18A. Further, in the state shown in FIG. 18B, the number parts 9D to 9F are turned off.

Finally, the appropriate segments are turned on so that the number portions 9D to 9F correspond to the position state of the CD tray 95 in FIG. 4, and the segments forming the outer frame 9G are also turned on.

According to this example, by blinking the segment of the outer frame 9H in which the rotation state of the CD tray 95 is arranged in an inverted triangle, it is possible to easily visually recognize that the CD tray 95 is rotating. ..

In the example described above, the segments of the number parts 9D to 9F corresponding to the placement numbers “1” to “3” are turned on, but in addition to this, the number frames 9A to 9C and the outer frame. The 9G segment may be constantly lit. For example, as shown in FIG. 19, while turning on the appropriate segments of the number parts 9D to 9F and turning on the segments g1 to g6 of the outer frame 9G, the segments a1 to a9, b1 to b9 and c of the number frames 9A to 9C are also turned on. Turn on 1 to c9. Note that FIG. 19 corresponds to the position state of the CD tray 95 of FIG.

According to the present example, the segments a1 to a6, b1 to b6, c1 to c6 and g1 to g6 of the number frames 9A to 9C and the outer frame 9G of the display element 9 are substantially the same as the shape of the CD tray 95. Since they are arranged so as to correspond to each other, the outer shape of the CD tray 95 can be easily visually recognized by turning on the segments of the number frames 9A to 9C and the outer frame 9G. Further, according to this example, the outer shapes of the plurality of mounting surfaces 97 to 99 are also displayed at the same time, so that the positional relationship between the mounting surfaces 97 to 99 can be easily visually recognized even after the CD tray 95 is stored. You can do it and give a sense of security.

According to this example, since the shape substantially corresponding to the outer shape of the CD tray 95G can be displayed on the display device 8, the user's taste can be satisfied.

In the case of the example in FIG. 19, the number frames 9A to 9C after the performance of the CD may be set to be turned off. Note that FIG. 19 shows a state before the three CDs placed on the placement surfaces 97 to 99 of the CD tray 95 are still played.

Then, for example, when the performance of the CD placed on the placement number “2” is completed and the CD placed on the placement number “1” is located at the reproduction position, FIG. As shown in, the segments b1 to b3, b8 and b9 of the number frame 9B corresponding to the placement number "2" are extinguished. In addition, when the playing of the CDs placed on the placement numbers “2” and “3” is completed and the CD placed on the placement number “1” is located at the reproduction position, FIG. As shown, the segments b1 to b3, b8, b9 and c2 to c6 of the number frames 9 and 9C corresponding to the placement numbers "2" and "3" are extinguished.

Furthermore, when the performance of all the CDs is completed, as shown in FIG. 22, the appropriate segments of the number parts 9D to 9F are lit up, and the segments a1 to a4 constituting the outer frame 9G are lit. b4 to b7, c7 to c1 and g1 to g6 are lit. In this case, for example, when the play is finished after the play button 69a is pressed to start the play, as shown in FIG. 26, a detection signal indicating that the reproduction of the CDs on the mounting surfaces 97 to 99 is finished is displayed. It is supplied from the optical pickup 57 to the microcomputer 152 to confirm the end of play. Then, under the control of the microcomputer 152, the segment of the number frame for which the display element 9 has finished playing is turned off.

Further, subsequently, for example, when the play is ended by pressing the change buttons 68a to 68e to start the play, a detection signal indicating that the reproduction of the CD on the mounting surface is completed is sent from the optical pickup 57. It is supplied to the computer 152 to confirm the end of play. Then, subsequently, the segment of the number frame where the display element 9 has finished playing is turned off.

According to this example, after the performance of the CD is finished, the segments of the number frames 9A to 9C of the display elements 9 corresponding to the placement numbers "1" to "3" at which the performance is finished are turned off. It is possible to easily visually recognize which one of the CDs placed on the surfaces 97 to 99 has already finished playing, and the subsequent play operation can be performed smoothly.

Although the display element 9 is composed of a plurality of segments in the above embodiment, the display element 9 may be composed of a plurality of dots. Further, in the above-described embodiment, the mounting surfaces 97 to 99 are formed at three places to show the tray 95 having a substantially triangular shape, but the shape of the tray and the number of mounting surfaces are not limited to this. Not done. In this case, the shape of the outer frame 9G of the display element 9 substantially corresponds to the shape of the tray.

Further, when the tray 70 is pulled out from the cabinet 10 and the two mounting surfaces of the tray 70 are opened, the number frames 9B and 9C corresponding to the mounting numbers of the mounting surfaces in the open state, Alternatively, the segments of the number parts 9E and 9F may be configured to blink. In this case, the mounting numbers "1" to "3" on the mounting surface where the CD can be exchanged can be easily visually recognized by the display of the display device 8.

Further, in the above-mentioned embodiment, the identification display for identifying the mounting surfaces 97 to 99 is the mounting numbers "1" to "3", but the identification display of the mounting surface is this. It is not limited to the above, and alphabets, stars, etc. may be used. In this case, the display by the display element 9 is made to substantially correspond to the identification display on the mounting surface.

In the above-described embodiment, the lighting control of the segment of the display element 9 is performed by supplying the detection signals of the optical pickup 57 and the sensors 88 and 89 to the microcomputer 152. Lighting control of the segments of the display element 9 may be performed by supplying an operation signal to the microcomputer 152 by operating an operation button.

Further, although the above-mentioned embodiment is an example of a disk device for a compact disk, the present invention can be applied to a disk device using other disks. Further, the present invention can be applied to a disc device of a format capable of recording in addition to reproduction.
