[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. 5 is a plan view of an example thereof. Reference numeral 1 denotes a tray, which is arranged so as to be drawn out to a cabinet 8 (shown by a chain double-dashed line in the figure). The tray 1 has a rotary shaft 1a protruding from the center thereof. Reference numeral 2 denotes 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 from the center of the tray 2 and a predetermined angular interval. A groove 4 is formed on the mounting surface 3 toward the center point thereof.

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 is displayed along the pull-out direction, so that the user can recognize which loading surface 3 the CD is loaded on. When the tray 1 is pulled out from the cabinet 8, only one mounting surface 3 (mounting surface with the mounting number “3” in FIG. 5) 3 is opened from the cabinet 8.

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 arranged so as to be slidable (movable in the front-back direction in FIG. 5) on a chassis (not shown). Reference numeral 7 is a disc crumb, which is arranged so as to be movable up and down.

When a CD is selected, 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 crumbler 7). Subsequently, the disc scrubber 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 disc clamper 7 rotates and the optical pickup 6 slides (moves forward in FIG. 5) to perform reproduction.

[0007]

[Problems to be solved by the device]

 In the example of FIG. 5, when the tray 1 is pulled out from the cabinet 8, only one mounting surface 3 is opened from the cabinet 8, and only one CD can be exchanged in that state. .. Therefore, if two or more of the plurality of mounting surfaces 3 are simultaneously opened from the cabinet 8, a plurality of CDs can be replaced at the same time even in that state, which is convenient. However, in this case, as shown in FIG. 6, if the placement numbers “1” to “3” are given along the line passing through the centers of the tray 2 and the placement surface 3, the cabinet 8 is released. The placement numbers on the placement surface (the placement numbers “2” and “3” in FIG. 6) are displayed in an oblique state with respect to the pull-out direction of the tray 2, and are difficult to see.

Therefore, the present invention provides a disk device in which two or more mounting surfaces are opened from the cabinet, and which mounting surface the disk is mounted on can be easily recognized.

[0012]

【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. It should be noted 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 slidably arranged in the front-rear direction on a holder 54 arranged at 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 obstructing 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 near 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.

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.

A sensor (not shown) is arranged on the tray 70 at a portion corresponding to the detection bodies 104 to 106 of the CD tray 95 described later. This sensor detects the position state of the mounting surfaces 97 to 99 of the CD tray 95 described later.

The CD tray 95 has an arc-shaped triangular shape with three sides, and has three mounting surfaces 97 to 99 on which CDs are mounted at predetermined angular intervals (120 degrees in this example). It is recessed.

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, a gear portion 102 as shown by a broken line 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 has a recess 101 formed 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 its back surface, 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 for detecting the second mounting surface 98 is arranged on the left side. 105 and a detection piece 106 arranged on the right side for detecting the third mounting surface 99.

Further, on the CD tray 95, protrusions 97 a to 99 a which are set to be slightly higher than the mounting surfaces 97 to 99 are formed on the outer peripheral portion between the notch 100 and the recess 101, respectively. The protrusions 97a to 99a are for restricting the movement of the CD.

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). Then, 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).

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 pull-out direction of the tray 70. Then, in this state, the CD can be exchanged with respect to the opened mounting surface.

A 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 rotates to a predetermined reproduction position (the mounting surface 97 in FIG. 4 corresponds to the disc support 56). In this state, the play button 69a is pressed to enter the play state. Reference numeral 67 is an open / close button for pulling out the tray 70 while maintaining the play state, and 69b is a stop button.

According to this example, since the placement numbers assigned to the placement surfaces opened from the cabinet 10 when the tray 70 is pulled out can be seen straight, the placement numbers “1” to “1”. 3 ”becomes easy to see, and the user can easily recognize on which of the mounting surfaces 97 to 99 the CD is mounted.

The above embodiment is an example in which two of the mounting surfaces 97 to 99 of the CD tray 95 can be opened from the cabinet 10 at the same time. The same can be applied when the number of mounting surfaces to be opened is three or more. Further, in the above-described embodiment, the display for identifying the mounting surfaces 97 to 99 is the mounting numbers “1” to “3”, but the display for identifying the mounting surfaces is not limited to this. , Alphabet, star, etc. may be used.

Further, in the above-described embodiment, the mounting numbers “1” to “3” of the mounting surfaces 97 to 99 are attached to the CD tray 95 so as to extend along the drawing direction of the tray 70. The display for identifying the mounting surface does not necessarily have to be along the pull-out direction of the tray 70 but may be in a slightly inclined state. For example, the display for identifying the mounting surface is provided toward the center of the CD tray 95. May be.
