Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recording / reproducing apparatus, and particularly to a recording / reproducing apparatus suitable for ejecting a recording medium of the recording / reproducing apparatus.

[0002]

[Prior art]

 Conventionally, many eject mechanisms of a recording / reproducing apparatus (hereinafter, simply referred to as a main body) shown in the perspective view of FIG. 3 have been provided. In the figure, reference numeral 1 is a main body of a recording / reproducing apparatus, and a front panel 1a of the main body 1 has a door 2 for covering and protecting a mounting opening of a recording medium which slides. The medium 5 can be attached. Reference numeral 6 denotes an eject key for ejecting the recording medium 5 mounted on the main body 1.

When the main body 1 of the recording / reproducing apparatus configured as described above is, for example, a CD changer of a CD player and the recording medium 5 mounted on the CD changer 1 is a CD magazine 5, the door of the CD changer 1 By sliding 2 to open as shown in the figure, inserting and inserting the CD magazine 5 from the mounting opening, and closing the door 2, it is possible to reproduce music or the like from the CD magazine 5.

In particular, in the case of a car audio CD changer 1 for a vehicle, a desired music can be selected from the mounted CD magazine 5 while the vehicle is being driven and can be listened to arbitrarily, so a CD that can be mounted in the CD magazine 5 Changer 1 is the optimal CD player.

[0005]

[Problems to be solved by the device]

 However, when the CD magazine 5 is taken out by the conventional CD changer 1 described above, the CD magazine 5 can be taken out by operating the eject key 6 provided on the surface of the panel 1a after opening the door 2 of the panel 1a. did it.

That is, in order to eject the CD magazine 5, the door 2 on the surface of the panel 1a needs to be opened, and further, the eject key 6 must be pressed to perform a two-step operation. ..

The present invention has been made in view of the above points, and the purpose thereof is to solve the drawbacks of the conventional example and to open the door 2 to immediately eject the CD magazine 5 from the CD changer 1. The present invention is to provide a recording / reproducing device.

[0008]

[Means for Solving the Problems]

 The recording / reproducing apparatus of the present invention is a recording / reproducing apparatus in which a door on the front surface of a panel is opened and a recording medium is mounted, and recording or reproducing is performed by the recording medium. The door is equipped with a protrusion that drives the door open detection switch, and when the door open detection switch is turned on, the recording medium mounted on the main body is ejected.

[0009]

[Action]

 According to this invention, there is a door that slides on the front surface of the panel of the recording / reproducing device to open and close, and a door opening detection switch is provided in the main body in the vicinity of which the door slides. When the door is slid and the opening operation is performed, the protruding portion of the door comes into contact with the door opening detection switch and drives the door opening detection switch to ON.

When the door open detection switch is turned on, the microcomputer with the built-in ON signal of the door open detection switch receives it, and after a time of about several tens of ms, the microcomputer controls the mechanical part of the main body. Then, the recording medium mounted on the main body can be ejected and taken out.

That is, when a user who is listening to music or the like from the recording medium wants to eject the recording medium for replacing the recording medium, for example, the user only has to perform the one-step operation of opening the door of the main body. The recording medium can be easily taken out with.

【Example】

 An embodiment of a recording / reproducing apparatus according to the present invention will be described with reference to FIGS. The same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a perspective view showing a main part of the recording / reproducing apparatus main body 1 with a part of the panel 1a surface cut away, and FIG.

In the figure, 3 is a door opening detection switch, the door opening detection switch 3 is provided in the main body 1 in the vicinity of the sliding of the door 2, and 4 is the above-mentioned when the door 2 slides and opens. It is a protrusion that drives the door opening detection switch 3.

FIG. 1 shows a state in which a door 2 provided on the front surface of the main body 1 is closed. A protrusion 4 is provided below the end of the door 2 as shown in FIG. Can slide in the direction of arrow A to open the surface of the panel 1a on which the recording medium 5 is mounted.

On the other hand, since the door opening detection switch 3 provided near the door 2 of the main body 1 is attached as shown in the figure, when the door 2 is opened, the protruding portion 4 of the door 2 is The door opening detection switch 3 can be driven by contacting the door opening detection switch 3. In this way, the opening operation of the door 2 can be detected by the ON / OFF operation of the door opening detection switch 3.

The ON / OFF signal of the door opening detection switch 3 is judged by, for example, a built-in microcomputer, and the microcomputer can control a mechanical section (not shown) and the like. This operation will be described with reference to the flowchart of FIG.

For example, when a user who is listening to music from the CD changer 1 which is a recording / reproducing device takes out the CD magazine 5 mounted on the CD changer 1, slides the door 2 of the panel 1a in the direction of arrow A. Then, when the protrusion 4 of the door 2 drives the door opening detection switch 3 to turn on (step S1), the built-in microcomputer determines that the door opening detection switch 3 is turned on (step S2). .

When the door open detection switch 3 is turned on, the microcomputer operates the built-in timer to count the wait time between 50 ms and 500 ms (step S3), and when the over time is reached, the door open detection is performed again. It is determined whether the switch 3 is in the ON state (step S4). If the door 2 is closed and the door open detection switch 3 is turned off while the microcomputer is counting the timer, the ejecting operation of the CD magazine 5 is disabled, and the first door open detection switch 3 is turned on. The process returns to the flow for determining the state (step S2).

If the door open detection switch 3 is still in the ON state in step S4, the microcomputer controls the mechanical portion of the main body 1 to eject the CD magazine 5 (EJECT) (step S5).

That is, when the user of the CD changer 1 takes out the CD magazine 5, the CD magazine 5 is automatically ejected by opening the door 2 on the panel 1a, and the CD magazine 5 with the door 2 opened. The CD magazine 5 can be taken out from the mounting opening.

Although the door opening detection switch 3 provided near the door 2 has been described as a mechanical push switch operation, the door opening detection switch 3 may be an optical switch or a reed switch, and the door 2 is a slide type. Not only the opening / closing mechanism, but also the tilting type opening / closing mechanism that can be opened to the front surface, or other vertical type opening / closing mechanism can be applied by performing the eject operation of the present invention.

[0022]

[Effect of the device]

 As described above, the eject mechanism of the recording / reproducing apparatus according to the present invention can detect the opening of the door on the panel surface and automatically eject the CD magazine mounted in the main body. Therefore, the eject mechanism can be operated in one step. There is an effect that the operation becomes possible and the operability can be improved.

In addition, the eject key as in the conventional example is not required, and the design is simple and good, and the cost can be reduced. Moreover, it has excellent features such as a simple structure and easy implementation because it can be constructed at low cost.
