DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an illumination structure for an information recording medium insertion / ejection port according to the present invention will be described with reference to FIGS. The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

This embodiment is an embodiment of a vehicle-mounted audio device using a CD as an information recording medium.

FIG. 1 is a perspective view showing an illumination structure of a CD insertion / ejection slot according to the present invention. FIG. 2 is a sectional view showing a main part of the lighting structure. FIG. 3 is a block diagram showing the wiring in this embodiment.

In FIG. 1, reference numeral 1 denotes a panel provided with various display devices and operation keys, which is driven by a motor 11 as a drive source via a drive mechanism (not shown) and attached to the audio equipment main body 3. The sub-panel 3a is lowered and inclined from a predetermined first position to a second position where the insertion / ejection opening 4 is completely exposed. In addition, the motor 11 drives from the second position and returns to the first position.

Reference numeral 2 denotes an LED serving as an illuminating means, which is disposed substantially at the center of the upper portion of the panel 1 and illuminates the entire insertion / ejection opening 4 with the panel 1 held at the second position.

A motor 11 shown in FIG. 3 is controlled by a control microcomputer 14 via a drive IC 15.

A switch 12 is provided on the upper part of the sub-panel 3a (see FIG. 2) of the audio equipment main body 3 and detects that the panel 1 is at the first position. When the panel 1 is mounted at the first position, the switch 12 is turned on and outputs an L signal.

Reference numeral 13 denotes a switch serving as detecting means, which is provided on the left side of the sub-panel 3a (see FIG. 1).
Has moved from the first position to the second position. When the panel 1 moves to the second position, the switch 13 turns on and outputs an L signal.

Reference numeral 14 denotes a control microcomputer, which is provided in the audio equipment main body 3, receives output signals from the switches 12 and 13, and controls the motor 11 via the drive IC 15.

Reference numeral 16 denotes a key provided on the panel 1 for moving the panel 1. Q1 is a transistor, LE
D2 is switching. R ₁ to R ₅ is a fixed resistor. B is a DC power supply.

The operation and operation of the present invention configured as described above will be described. When the operation key 16 provided on the panel 1 is instructed to move the panel 1, the microcomputer 14 receives a signal from the operation key 16 and outputs a drive signal for the motor 11.

As a result, the motor 11 is driven, and the panel 1 is lowered from the vertically mounted first position and tilted,
It is held in the second position shown in FIGS.

At this time, the switch 13 shown in FIG. 3 provided in the audio equipment main body 3 is turned on, and outputs an L signal to the microcomputer 14 while simultaneously outputting the transistor Q1.
Is turned on to cause the LED 2 to emit light. When the LED 2 is turned on, the entire insertion / ejection opening 4 of the CD is illuminated as shown in FIG.

On the other hand, the microcomputer 14 which has received the L signal from the switch 13 outputs a stop signal to the motor 11, and the driving of the motor 11 is stopped.

The operation key 16 allows the panel 1 to be moved to the first position.
When instructed to return to the position, the microcomputer 14 receives a signal from the operation key 16 and outputs a drive signal for the motor 11.

As a result, the motor 11 is driven, and the panel 1 returns from the second position to the first position by following a path reverse to the above-described movement path, and is mounted at a predetermined position.

When the panel 1 leaves the second position, the switch 13 shown in FIG. 3 is turned off, the transistor Q1 is turned off, the light emission of the LED 2 is stopped, and the illumination is turned off.

At this time, the switch 12 shown in FIG. 3 is turned on, and outputs an L signal to the microcomputer 14. The microcomputer 14 receiving this L signal
A stop signal is output to the motor 11, and the driving of the motor 11 is stopped.

As described above, when the panel 1 is moved to the second position, the LED 2 is turned on to illuminate the entire insertion / ejection opening 4 of the CD from obliquely below, so that the CD can be inserted immediately when illuminated. I have. After leaving the second position, the illumination is turned off and the CD cannot be inserted.

In this embodiment, the switch 13 is provided on the sub-panel 3a side of the audio equipment main body 3. However, the present invention is not limited to this, and the switch 13 may be provided on the panel 1.

The information recording medium inserted / ejected from the insertion / ejection opening 4 is not limited to a CD, but may be another recordable / reproducible disk, cassette tape or storage element.

[0032]

According to the illumination structure of the information recording medium insertion / ejection port according to the present invention, since it is constructed as described above, after the panel moves to the second position where the insertion / ejection port is completely exposed, the LE
Since D2 is turned on to illuminate the entire insertion / ejection opening, the visibility of the CD insertion / ejection opening is greatly improved, and the timing at which a CD can be inserted becomes clear. For this reason, the CD is not damaged at the time of insertion.

Also, since the LED can be mounted on a printed circuit board for operation keys provided in the panel,
This eliminates the need for a printed circuit board on the sub-panel side on which is mounted, thereby reducing the cost of parts and greatly reducing the number of work steps.
