2. Description of the Related Art In a changer type disc reproducing apparatus such as a CD (compact disc) changer, it is necessary to easily determine which of a plurality of disc holding units holds a disc and which is empty. Conventionally, the presence or absence of a disc on each disc holder is determined by a sensor provided inside the device,
In general, the discrimination information is displayed on an LED or LCD on a display provided on the front panel of the apparatus, but it is more convenient if the presence or absence of a disc on each disc holding portion can be visually confirmed.

Conventionally, there has been a CD changer shown in FIG. 2 in which the presence or absence of a disc on each disc holder can be directly visually recognized. The CD changer 10 has a tray inlet / outlet 16 provided on a front panel 14 of a cabinet 12, and a tray 18 is arranged so as to be slidable in the cabinet 12 by sliding the tray 18 horizontally. A rotary table 20 is rotatably arranged on the upper surface of the tray 18. On the upper surface of the rotary table 20, a plurality of sheets (generally 3 to
Five (22) CDs 22 are held, and any CD can be transferred to the position of the reproduction unit and reproduced. A window 24 is formed in a top cover 26 that constitutes the upper surface of the cabinet 12, and all the CDs 22 housed inside can be viewed through the window 24.
The front panel 14 includes an operation unit 30 and various information such as LEDs and L.
A display 28 for displaying on a CD is provided.

[0004]

In the CD changer 10 of FIG. 2, the top cover 26 of the cabinet 12 is used.
When an object is placed on the window 24, the window 24 is closed and the inside cannot be seen. Further, because of the design limitation that the tray 18 must be laid out so that the tray 18 is directly below the top cover 26, the display 28 must be disposed on the front panel 14 and below the tray entrance / exit 16. Therefore, when the tray 18 is opened, the display 28 becomes difficult to see. Moreover, in a dark room, the inside cannot be seen through the window 24.

The present invention solves the problems of the prior art, and makes it possible to easily visually recognize all the internal disks even when an object is placed on a cabinet or in a dark room.
Moreover, it is an object of the present invention to provide a changer type disc reproducing apparatus which can easily adopt a layout in which trays are arranged so as not to disturb the display.

2 is rotatably arranged around a rotary shaft 56. On the upper surface of the rotary table 42, disc holding portions 44, 46, 48 (recesses) are formed at three locations around the rotary shaft 56 at equal intervals, and one disc holding portion is provided for each disc holding portion 44, 46, 48. The CDs 50, 52, 54 can be placed and held.

A reproducing unit 58 having a spindle motor, an optical pickup, and the like is mounted on the chassis at a central portion in the width direction of the interior of the cabinet 34. When the tray 40 is housed in the cabinet 34 and an instruction to reproduce a CD in an arbitrary disc holding portion is given from the outside,
The rotary table 42 rotates, the corresponding disc holding portion is transferred to the position of the reproducing unit 58, and the CD held in the disc holding portion is pulled up by the turntable of the reproducing unit 58 to perform reproduction. Be done.

A cover 72 is fixed to the chassis above the tray 40 in the cabinet 34. Cover 7
A cylindrical curved mirror 76 and an internal illumination 74 are held at 2. The cylindrical curved mirror 76 is a mirror having a cylindrical inner surface (concave surface) or outer surface (convex surface) as a reflecting surface, and for example, as shown in FIG. 4, a metal having a shape obtained by cutting a part of a cylinder in the axial direction, It can be configured by forming a reflection film on the inner surface or the outer surface of the member 94 such as plastic. The cylindrical curved mirror 76 is disposed above the disc holding portion 44 located in the interior of the cabinet 34 so as to extend in the width direction of the tray 40. The length of the cylindrical curved mirror 76 and the height in the vertical direction are determined by the smoke window 68.
All of the label surfaces of all the CDs 50, 52, 54 are formed so that at least a part thereof can be seen. Interior lighting 62
Is the tray 4 at a position before the cylindrical curved mirror 76.
It is arranged so as to illuminate the rotary table 42 at the central portion in the width direction of 0. Internal lighting 74 is CD changer 32
In the state where the power switch is turned on and the tray 40 is stored in the cabinet 34 (the detection state of the tray 40 is detected by the detection means such as a limit switch).
Light. When the tray 40 is discharged from the cabinet 34, the light is turned off and the inside cannot be seen through the smoke window 68. It is also possible to separately provide a switch for forcibly turning off the internal illumination 74 and forcibly turn off the light when the tray is stored.

A smoke window 68 as a window portion is arranged so as to extend in the lateral direction at a position where the cylindrical curved mirror 76 of the front panel 36 faces in the horizontal direction. The smoke window 68 is formed in such a size that the entire cylindrical curved mirror 76 can be easily seen. The smoke window 68 is made of a light-colored transparent glass plate or a transparent plastic plate. When the internal illumination 74 is on, the inside can be seen, and when it is off, the inside cannot be seen. Above the smoke window 68 on the front panel 36, LE
Display 66 and operation unit 64 such as D and LCD
And so on. Display 66 and operation unit 6
4 is above the tray 40, the tray 40
It can be easily viewed or operated even when the is open. In the four corners of the lower surface of the cabinet 34,
Rubber legs 70 are attached.

FIG. 1 is a sectional view taken along the line DD in FIG. 1A when the tray 40 is housed in the cabinet 34 and the CD 50 of the disc holding portion 44 is being reproduced. In the reproducing unit 58, the CD 50 is pulled up from the disc holding portion 44 by the turntable 80, clamped by the disc clamper 84, is rotated by the spindle motor 78, and the recorded information is read by the optical pickup 82.

Interior lighting 74 includes a smoke window 68.
The light source 88 is hidden by the recess 86 of the cover 72 so that the light source cannot be directly seen from the above, and the light 88 is emitted obliquely downward and rearward so as to irradiate all the disk holding portions 44, 46, 48. . The cylindrical curved mirror 76 is formed of a convex mirror here. The cylindrical curved mirror 76 is arranged above the front portion of the disk holding portion 44 at the back, with the reflecting surface 76a facing obliquely forward and downward.

According to the above configuration, the CD changer 3
When the power switch of No. 2 is turned on, the internal illumination 74 is turned on in the state where the tray 40 is housed, the label surfaces of the three CDs 50, 52 and 54 on the tray 40 are illuminated, and the image is a cylindrical curved mirror. The light is reflected at 76 and guided to the outside through the smoke window 68. An internal reflection image seen through the smoke window 68 when the CD 50 is reproduced is shown in FIG. The operation of the cylindrical curved mirror 76 at that time is shown in FIG. This reflection image is vertically reversed (reverse characters) and becomes a vertically compressed image. Whether or not there is a CD in each of the disc holding portions 44, 46, 48,
You can check what the CD is, whether it is being played, etc.

Further, since the cylindrical curved mirror 76 is used, the height required to reflect the images of the three CDs 50, 52 and 54 is low, and the arrangement can be performed even if the space on the tray 40 is narrow. . By the way, when the plane mirror is used, as shown in FIG. 6, the height of the plane mirror 90 needs to be high in order to project the three CDs 50, 52, 54, and the space on the tray is small. And cannot be placed. Alternatively, as shown in FIG. 7, by arranging the plane mirror 92 further on the back side to make the incident angle with respect to the CDs 50, 52, and 54 shallower, the height of the plane mirror 92 is suppressed, and three Cs are provided.
When the D50, 52, and 54 are projected, the CD 52 and 54 are hidden behind the CD 50, making it difficult to see the CDs 52 and 54, and it becomes difficult to know the presence or absence of the disc.

In the case of using the cylindrical curved mirror 76 (convex mirror) of FIG. 1, by disposing a cylindrical convex lens between the mirror 76 and the smoke window 68 in parallel with the mirror 76, the mirror 76 The reflected image compressed up and down can be enlarged and corrected with. Further, instead of the convex mirror, as shown in FIG.
By using 6 ', it is possible to obtain a reflection image of a regular character whose upper and lower sides are not inverted as shown in FIG. 6B, and it becomes easy to read the character on the label surface. Also in this case, the mirror 7
By disposing a cylindrical convex lens in parallel with the mirror 76 'between 6'and the smoke window 68, the mirror 7'
The reflected image compressed vertically by 6'can be enlarged and corrected. The present invention can also be applied to a changer type disc reproducing apparatus for reproducing discs other than CDs.

[0017]

As described above, according to the present invention, all the disks inside can be visually recognized through the window formed on the front panel, and the object can be placed freely on the cabinet. Further, since the arrangement position of the tray in the vertical direction is not restricted, the mount position of the changer mechanism can be freely set, and the layout in which the display is easy to see can be easily adopted. Also, since a cylindrical curved mirror is used, the height of the vertical mirror required to display the entire disc is low, and it can be easily placed even in a narrow space on the tray and the height of the cabinet can be increased. It can be kept low.
