It is. Eject control means used in the present invention is not particularly limited, but may be a human operation, or electrical, optical,
Further, any device having a function of operating the auto-eject mechanism using magnetic means can be used.

In the present invention, a particularly simple switch mechanism such as an eject key and an eject button may be employed. What is important in the present invention is that the ejection control means 6 needs to be controlled by the positional relationship of the cover portion 2. Specifically, the ejection control means 6 The cover 2 is the magazine insertion port 4
Is configured to be effective only when the front surface is completely opened. That is, the eject control means 6 according to the present invention comprises a switch mechanism such as an eject key, an eject button, etc., while the cover 2 does not completely open the front surface of the magazine insertion slot 4. Even if the eject control means 6 is operated, the auto-eject mechanism is not operated, so that there is no possibility that the magazine is inadvertently ejected and comes into contact with the cover 2.

In the embodiment shown in FIG. 1, the eject control means and the cover are physically engaged, and only when the cover completely opens the front surface of the magazine insertion slot. The physical relationship between the ejection control means and the cover is released, and the operation of the ejection control means becomes effective.

That is, in FIG. 1A, the cover 2 is provided on the front surface of the main body of the CD auto chainer.
A control piece 7 is provided at the lower end of the cover 2, and the control piece 7 is physically engaged with the groove 9 of an eject key 66, which is one of eject control means having the groove 9. On the other hand, a notch 10 is formed in the left end 8 of the control piece 7.
Are formed. As shown in FIG. 1 (B), the notch 10 has reached a position where the cover 2 slides to the rightmost side and the front surface of the magazine insertion slot 4 is completely opened. The position where the ejection key 66 is sometimes disengaged from the groove 9 is selectively formed.

Therefore, while the cover 2 is in a state where the front surface of the magazine insertion slot 4 is not completely opened,
No matter how the eject key 66, which is the eject control means 6, is pressed, the auto eject mechanism does not operate because the key is not operated. However, the cover 2 is completely covered with the front of the magazine slot 4. When the position reaches the position where the eject key 66 is released, the groove 9 of the eject key 66 is released from the engagement with the control piece 7 of the cover 2, so that the operation of the eject control means 6 becomes effective. By pressing the eject key 66, the magazine is automatically ejected.

As another example according to the present invention, as shown in FIG. 2, an open position detecting means 11 for detecting a state where the cover 6 completely opens the front surface of the magazine insertion slot 4 is provided. The operation of the eject control means 6 is made effective in response to the output signal of the open position detection means 11. Specifically, unlike the mechanical engagement relationship shown in FIG. 1, the cover portion 2 is located at any appropriate position of the CD auto-chair, preferably near the sliding portion of the cover portion 2. Provided means for detecting the position when the front of the magazine insertion opening 4 is completely opened, using a detection signal of the detection means,
The operation of the ejection control means 6 is made effective, that is, the ejection control means 6 is actuated, and the ejection key 66 is pressed to activate the automatic ejection mechanism.

As the open position detecting means 11, any type of limit switch can be used as long as it can detect the position of the cover 2 using electrical, optical or magnetic means. I can do it. Open position detecting means 1
By transmitting the detected output signal (1) to appropriate switching means provided in the body ejection control means using appropriate circuit means, the ejection control means becomes effective.

Next, as another specific example of the CD auto-changer according to the present invention, there is an embodiment in which the eject control means includes the open position detecting means. That is, in the present embodiment, the eject control means 6 and the open position detecting means 11 are also used, and the number of switch means can be reduced as compared with the above-described specific example.

Specifically, the detection switch of the open position detection means 11 shown in FIG. 2 also functions as the operation instruction means of the auto-ejection mechanism. FIG. 3 shows an example of a control circuit for a CD auto-changer according to the present invention. That is, one end of the excitation circuit R for driving the motor M for driving the auto-eject mechanism according to the present invention is connected to the power supply + B, and the other end is grounded via the drive transistor 12, and the base of the transistor is The control signal of the eject control means 6 is inputted to the control unit.

In the first embodiment of the present invention, the switch 6 which can be pressed only when the cover 2 reaches a position where the front face of the magazine slot 4 is completely opened is set. It is configured to be connected to the base of the transistor and to supply a voltage sufficient to make the transistor conductive through the switch 6. In a second specific example, the output of the switch of the eject control means 6 The output of the open position detecting means 11 for detecting that the cover 2 has reached a position where the front surface of the magazine insertion opening 4 is completely opened is connected to the base of the transistor 12 through an AND gate circuit 13. It can be executed by connecting to.
Also, in the third specific example, A in the second specific example
This can be easily performed by short-circuiting the input of the ND gate circuit 13.
