DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an audio device in which a CD player and a cassette deck are integrated. First, the configuration of the audio device will be described. Reference numeral 1 denotes a rectangular parallelepiped cabinet, and a front panel 1a is arranged on one surface (left surface in the figure) of the cabinet. A tray receiver 2 includes a base 3, a side wall 4, and a cone receiver 5. The base 3 has a flat plate shape, on which a tray 10 described later is placed. A hole 3a is formed substantially in the center of the base 3. This hole 3a
Is for inserting the motor shaft 6 fixed to a motor (not shown). At one end (upper end in the figure) of the motor shaft 6, a disc clamper 8 for mounting a CD 7 is placed.
And the cone 9 is fixed. The side walls 4 project upward from both side ends of the base 3 and regulate the position of the tray 10. The cone receiver 5 is arranged only at a portion corresponding to the disc crumbler 8 and the cone 9, and is horizontally stretched between the side walls 4. The height of the cone receiver 5 is set to be slightly higher than the height of the tray 10. A hole 5a is formed in a portion of the cone receiver 5 corresponding to the cone 9. The hole 5a has substantially the same shape as the disc clamper 8 and the cone 9.

Reference numeral 10 is a tray on which the CD 7 is placed. A notch 11 is formed in the tray 10 substantially at the center thereof on one side (right side in the drawing). This notch 11 is a tray 10
This is for avoiding a collision between the tray 10 and the cone 9 when the slide is moved. Reference numeral 12 denotes a mounting surface on which the CD 7 is mounted, which is circular like the CD 7. The mounting surface 12 is arranged slightly lower than the upper surface of the tray 10. At the center of the mounting surface 12, a hole 13 having a diameter larger than that of the disc clamper 8 is formed. A peripheral groove 14 is formed on the outer circumference of the mounting surface 12 along the outer circumference. A locking means (not shown) is provided on one end side (notch 11 side) of the tray 10 to prevent the tray 10 from coming out of the cabinet 1.

Reference numeral 16 is a transmitting device (hereinafter referred to as "commander") for operating the operation of the audio device. This commander 1
The operation switches A1 to A5 arranged in 6 are arranged in a matrix of 5 rows and 5 columns. Reference numeral 15 denotes a tray of the commander 16, which is arranged on the upper stage of the tray 10. The tray 15 has a storage chamber 17 in which the commander 16 is detachably stored.

A relief 15b is formed near the center of the lower end of the front plate 15a of the tray 15. In addition, the tray 15 is at a position where all the storage chambers 17 are opened (position shown in FIG. 3).
Locking means (not shown) for stopping at is arranged. The tray 15 is opened and closed by a push-push type lock mechanism (not shown). Further, although not shown, a means for stopping the tray 15 in the middle of pulling out is configured as follows. That is, the both sides of the tray 15 are engraved with locking portions having a substantially V-shaped cross section. Leaf springs are arranged on the chassis (not shown) so as to face both side surfaces of the tray 15. The leaf spring has a hook portion that is substantially the same as the locking portion. The hook portion and the side wall of the tray 15 are arranged so as to be in contact with each other. The commander 16 is stopped halfway by the hook portion being locked to the locking portion. In this case, the positional relationship between the engaging portion and the hook portion enables the CD 7 to be attached to and detached from the tray 10, and among the operating switches, the operating switches A1 and A2 (CD7
Related operations, such as playing and stopping, are opened.

Reference numeral 19 denotes a light receiving window, which is used when the commander 16 is detached from the tray 15 for use.
This is for guiding the optical signal from the inside of the cabinet 1. That is, the light receiving window 19 is formed of a synthetic resin capable of transmitting the optical signal from the commander 16. The light receiving window 19 is flush with the front panel 1a of the cabinet 1 in the tray 15
Placed above. Reference numeral 20 denotes a light receiving element, which is the wiring board 1.
It is attached to c. This light receiving element 20 has a light receiving window 1
It is arranged at a position opposed to 9. A cassette mechanism 21 is arranged above the cabinet 1.

Here, the tray 15 of the commander 16 is set to a CD.
The tray 10 of No. 7 is arranged above the tray 10 so that the operation switches A1 and A2 of the commander 16 can be pressed even when the CD 7 is attached or detached. That is, tray 15 to tray 1
This is because if they are arranged in the lower stage of 0, the pressing operation of the commander 16 is hindered when the tray 10 is pulled out.

Reference numeral 30 denotes a condenser lens which is attached to the chassis so as to face the light emitting direction of the light emitting element 16a of the commander 16 in the tray 15. The condenser lens 30 condenses the optical signal from the light emitting element 16a. Reference numeral 31 is a reflecting prism, which is attached to the chassis. The reflecting prism 31 is arranged at a position where it does not prevent the optical signal from the light receiving window 19 from being supplied to the light receiving element 20, and the optical signal from the reflecting prism 31 can be supplied to the light receiving element 20. 32
Is a light guide cable (for example, acrylic optical fiber), and optically connects the condenser lens 30 and the reflection prism 31. The light guide cable 32 is for supplying an optical signal to the condenser lens 30 to the reflection prism 31.

In this example, first, in order to open the tray 15 from the state of FIG. 1 to the vicinity of the operation switches A1 and A2 in advance, the front plate 15a is pressed. As a result, the lock of the push-push type lock mechanism is released. Then, the tray 15 is moved to the cabinet 1 by the biasing force of the spring that always biases the tray 15 toward the front panel 1a.
Pulled out from within. That is, the tray 15 is pulled out with its side surface and the hook portion of the leaf spring contacting each other. When the tray 15 is pulled out to the vicinity of the operation switches A1 and A2, the locking portion of the tray 15 engages with the hook portion of the leaf spring, so the tray 15 stops in the middle of pulling out (standby state) (see FIG. 2). .

In this state, the front panel 1 of the cabinet 1
When the opening / closing button (not shown) of the tray 10 arranged in a is pressed, the tray 10 is pulled out from the cabinet 1 as shown in FIG. Then, the CD 7 is placed on the placing surface 12 of the tray 10. At this time, the front plate 15a of the upper tray 15 is positioned near the mounting surface 12 as shown in FIG. 2, so that the CD 7 is not hindered from being mounted. In particular, since the escape 15b is formed near the center of the lower end of the front plate 15a, the CD 7 can be placed well as shown in FIG.

When the opening / closing button of the tray 10 is pressed again after the CD 7 is placed, the tray 10 is stored in the cabinet 1. Note that the motor shaft 6 moves up and down in conjunction with the tray 10 loading / unloading operation. Then, as the motor shaft 6 rises, the cone 9 is fitted into the rotation hole 7a of the CD 7, and the CD clamper 8 lifts the CD 7 in a state of overlapping with the CD 7. The motor shaft 6 rises until the cone 9 fits into the hole 5a of the cone receiver 5. After the storage, the operation switches A1 and A2 for operating the CD 7 arranged on the commander 16 are pressed to perform an operation related to the CD 7, such as a reproduction operation. That is, the remote control signal corresponding to the pressed operation switches A1 and A2 is output from the light emitting element 16a as an optical signal (infrared ray).

In this case, the optical signal from the commander 16 is condensed by the condenser lens 30 and further supplied to the reflection prism 31 via the light guide cable 32. Then, the light is reflected by the reflection prism 31 and supplied to the light receiving element 20. This controls the operation of the audio device.

In order to further pull out the tray 15, the user pinches and pulls the vicinity of the front plate 15a. This pulling force releases the engagement between the locking portion of the tray 15 and the hook portion of the leaf spring. Therefore, due to the urging force of the spring, the tray 15 is moved to its storage chamber 1 as shown in FIG.
It is withdrawn until all 7 are released. Then, since all the operation switches A1 to A5 are opened, the cassette mechanism 21 can be operated by the operation switches A3 to A5 for operating the cassette, for example. The operation control of the audio device in that case is the same as in the above case.

Next, when the commander 16 is to be remotely controlled, the commander 16 is first taken out from the storage chamber 17 of the tray 15. Then, as shown in FIG. 4, the user operates the operation switches A1 to A1 with the light emitting element 16a of the commander 16 facing the light receiving window 19 of the cabinet 1.
Press A5. As a result, the remote control signal is output as an optical signal from the light emitting element 16a, and this optical signal is transmitted through the light receiving window 19 and supplied to the light receiving element 20. That is, the operation of the audio device is controlled as described above. The CD 7 is taken out from the tray 10 in the reverse order of the above-mentioned device.

According to this embodiment, since the commander 16 is arranged in the drawer type tray 15, the operation buttons for the CD 7 and the like are not required on the front panel 1a, the number thereof can be reduced, and the appearance can be improved.

Further, according to this example, the tray 15 arranged on the upper stage of the tray 10 can be attached / detached to / from the CD 7 and can be stopped halfway in a state where the operation switches A1 and A2 relating to the CD 7 are ejected (standby state). Therefore, after the tray 10 is stored in the cabinet 1, the operation switches A1 and A2 of the commander 16 in the storage chamber 17 can be pressed immediately. The operation related to CD7 can be performed quickly.

Further, according to this example, the condenser lens 30 is arranged so as to face the output direction of the light emitting element 16a of the commander 16 in the tray 15, and the optical signal is passed through the light guide cable 32 and the reflection prism 31. Since the light is guided to the light receiving element 20, only one light receiving element is required, so that the cost can be reduced.

FIG. 5 shows a condenser lens 30 and a light guide cable 3.
2, an example in which mirrors 41 to 42 are arranged instead of the reflecting prism 31. The mirror 40 is arranged in the tray 15 so as to face the output direction of the light emitting element 16a of the commander 16. The angle is set to redirect the emission up 90 degrees. The mirror 41 is arranged to face the mirror 40 at a position higher than the light receiving element 20. The angle is mirror 4
It is set so that the light emission from 0 is turned to the direction of the light receiving element 20. The mirror 42 is arranged so as to face the mirror 41. The angle is determined by the optical signal from the mirror 42
It is set to change the direction so that it can be supplied to 0.

In this example, the commander 16 is placed in the storage chamber 17
When the operation switches A1 to A5 are pressed inside, the optical signal from the light emitting element 16a is supplied to the mirror 40, and is supplied to the light receiving element 20 via the mirrors 41 and 42. Other functions and effects are similar to those of the above-described embodiment.

In the above embodiment, the operating member for the opening / closing button of the tray 10 is provided in the cabinet, but FIG. 6 shows an example in which the operating member for the opening / closing button of the tray 10 also serves as the light receiving window 19. . The fixed end (upper end in the figure) of the light receiving window 19 is fixed to the front panel surface 1a with a screw 51. The light receiving window 19 is held by this fixing means. A hinge portion 52 is formed in a curved shape near the window portion 50 at the fixed end. Free end side of window 50 (lower side in the figure)
Are movably arranged. Further, an operating rod 53 extends horizontally (in the left-right direction in the drawing) on the free end side.
A tact switch 54 is disposed on the wiring board 1c at a position facing the tip of the operating rod 53. And the operating rod 5
The tip of No. 3 and the tact switch 54 are arranged close to each other.

In this example, in order to open and close the tray 10, the user first presses the window 50. As a result, the light receiving window 19 tilts counterclockwise about the screw 51 as a fulcrum. At this time, the window portion 5 of the light receiving window 19 is provided on the fixed end side.
Since the hinge portion 52 is arranged closer to 0, the hinge portion 52 formed in a curved shape facilitates the tilting of the light receiving window 19. Then, the operating rod 53 arranged on the free end side moves to the wiring board 1c side (right side in the drawing) and moves to the tact switch 54.
Press. By this pressing, an operation signal from the tact switch 54 is supplied to the control system to open or close the tray 10. The light receiving window 19 guides and supplies the optical signal from the commander 16 to the light receiving element 20 as in the conventional case.
The type of the light receiving window 19 is not limited to the pressing type, but can be applied to, for example, a sliding type.

According to the present example, the light receiving window 19 has the commander 16
The optical signal from the tray 1 can be supplied to the light receiving element 20, and the tray 1
The function of the 0 open / close button can be exhibited.
That is, since the light receiving window 19 is also used as the operation member for the opening / closing button of the tray 10, the operation member for the tray 10 conventionally arranged on the front panel surface 1a can be eliminated and the number of parts can be reduced. The cost can be reduced and the appearance can be improved.

In the above-mentioned embodiment, the lower tray 10 which is a container is used for a CD, but the container is not limited to this, and can be applied to, for example, a cassette holder. Further, the commander 16 which is the operating body is detachably arranged on the tray 15. However, the operating body is not limited to this, and the commander and the tray may be integrally fixed. Further, although the tray 15 which is the operating body is arranged so as to be drawn out, the operating body is not limited to this, and the commander itself may be arranged so as to be drawn out, for example. Furthermore, the stop position and the number of stops of the tray 15 can be set arbitrarily.
