This position is coincident with the center of the guider 42. The lifting shaft 90 should have sufficient stroke such that the seating portion 92 is at least above the slider 52 upon lifting. A limit switch S2 operated by the connecting piece 86 is disposed at the lower end of the feed shaft 84 to stop the operation of the driving motor 82 when the lifting shaft 90 descends to a predetermined position.

According to the present invention, it is preferable that the driving motors 30 and 82 driving the magazine 20 and the lifting shaft 90 each use a stepping motor with easy pulse control. By using a stepping motor, the position of the magazine and the lift shaft is controlled by pulse control at the forward rotation, and the position control of the magazine and the lift shaft is performed by the limit switches S1 and S2 provided at the reverse rotation.

The lower part of the guider 42 is provided with supporting means for receiving the CD 22 mounted on the seating portion 92 of the lifting shaft 90 and separating it from the CD writer 50. The supporting means includes a pair of clamps 64 arranged between the seating portion 92 of the lifting shaft 90 in the raised state and the slider 52 of the CD lighter 50, and the clamps 64 are always It is composed of a spring 66 to elastically support to maintain the expanded state, and the solenoid 60 to operate in a direction in which the clamp 64 is reduced to overcome the elastic force of the spring 66 by the electrical signal. The pair of clamps 64 are respectively coupled to both ends of the operating piece 62 whose central portion is connected to the solenoid 60 as shown in FIG. 3A so that the radius of the CD 22 when the solenoid 60 is actuated. It moves inward to limit the lowering of the CD 22 mounted on the seating portion 92.

Referring back to Figure 1, the present invention is provided with a discharge means for guiding the CD 22 falling from the clamp 64 to the front of the main body 10 in the lower portion of the CD writer 50. The discharge means has a discharge chute 74 which guides the normal CD 22 to the outlet, and is rotatably arranged on the upstream end of the discharge chute 74 with respect to the fixed shaft 72 to prevent the defective CD 22. It consists of an operating chute 70 that guides through another path. Under the operation chute 70, a drive motor 77 connected to the operation chute 70 by a link 76 is disposed. The operating chute 70 delivers the CD 22 to the discharge chute 74 in the case of the normal CD, and rotates downward by the operation of the drive motor 77 to discharge the CD 22 in the case of the defective CD. It is configured to feed into the defective CD box 100 located in the lower portion of the chute (74). Here, the drive motor 77 shows an example in which a conventional DC motor is applied, and a pair of rotary plates 78 connected to the shaft and operated by an operation pin 79 fixed to the rotary plates 78 is used. Rotation is controlled by limit switches S3 and S4 of which one of the limit switches S4 outputs a signal at the normal CD ejection position to stop the operation of the drive motor 77 and the other limit. The switch S3 is configured to stop the operation of the drive motor 77 at the defective CD ejection position.

It describes the operating state of the CD ejection apparatus according to the present invention having such a configuration. First, in the initial state, as shown in FIG. 4A, the initial state, that is, the slider 52 enters the inside of the CD writer 50, and the lifting shaft 90 maintains the lowering state.

When the tune is selected by the user in this state and the start signal is input, first, as shown in FIG. 4B, the slider 52 is released from the CD writer 50, and then, as shown in FIG. 4C, The driving motor 82 is operated so that the lifting shaft 90 rises through the slider 52. Then, the drive motor 30 is operated to start the magazine 20 in the direction of the arrow. As the magazine 20 moves, when the CD 22 positioned at the tip reaches the inlet 24, the CD 22 falls through the inlet 24. At this time, the detection sensor 26 detects the falling CD 22 and outputs an electric signal, the drive motor 30 is stopped by this signal. Therefore, the magazine 20 is moved by the interval (pitch) between the CD and the CD by one start signal input from the user.

The CD 22 falling through the input port 24 slides the input chute 40 to enter the guider 42. At this time, the CD 22 is disposed such that the recording surface faces the bottom of the feeding chute 40, and the CD 22 is seated on the seating portion 92 positioned at the lower end of the guider 42. The mounting portion 92 is inserted into a setting hole (not shown) formed in the center of the conventional CD 22 to align the CD 22 in a predetermined shape.

When the CD 22 is aligned on the seating portion 92 as described above, the driving motor 82 reversely rotates and the lifting shaft 90 descends. As the lifting shaft 90 descends, the CD 22 seated thereon descends together, and the CD 22 rests on the slider 52 when the seating portion 92 passes through the slider 52. do. Therefore, from here, only the seating portion 92 continues to descend, and when the connecting piece 86 reaches a predetermined position, the limit switch S2 detects the connecting piece 86 and outputs an electric signal, and the driving motor 82 This signal is stopped. (This state differs only in the position of the CD 22, and is generally in a form consistent with FIG. 4B.)

When the lowering of the lifting shaft 90 is completed, the slider 52 enters the CD writer 50, and the CD writer 50 stores the music set by the user on the CD 22. (This state differs only in the positions of the CD 22 and the magazine and is consistent with 4A as a whole.

When the recording of the music is completed, the slider 52 rises and returns to the state as shown in FIG. 4B, and then the lifting shaft is raised by the operation of the drive motor 82. As the lifting shaft 90 rises, the seating portion 92 lifts the recorded CD 22 seated on the slider 52 at the time when passing through the slider 52, and is in a state as shown in Fig. 4C.

When the ascending of the seating portion 92 on which the recorded CD 22 is seated is completed, the solenoid 60 is operated as shown in FIG. 5, whereby a pair of clamps 64 are connected to the CD 22. It will move radially inward from the bottom.

As such, when the clamp 64 is completed entering the lower portion of the CD 22, the driving motor 82 reversely rotates again, and the lifting shaft 90 starts to descend. When the lifting shaft 90 is lowered, the recorded CD 22 is caught on the clamp 64 at a predetermined position and placed on the clamp 64, and only the seating portion 92 continues to descend, and the limit as described above. The switch S2 reaches the down position and stops.

Subsequently, when the slider 52 enters the CD writer 50 and the power supplied to the solenoid 60 is cut off, the pair of clamps 64 are elastic by the spring 66 force as shown in FIG. 3. Will be restored. Therefore, the recorded CD 22 which has been placed on the clamp 64 falls down and falls on the operation chute 70. The recorded CD 22 dropped to the operation chute 70 is moved downward and discharged out of the main body 10 through the discharge chute 74.

On the other hand, in the ball design, when the CD 22 scheduled to be recorded enters the CD writer 50 as described above, the CD writer 50 determines whether the CD 22 is defective, and in the case of the normal CD, the above-described process is performed. Are sequentially performed, and when the CD 22 is defective, the control signal is output to operate the driving motor 77. Accordingly, the operation chute 70 rotates downward based on the fixed shaft 72 to maintain the defective position, that is, as shown in FIG. 4D. In this state, when the CD writer 50 discharges the defective CD 22 by performing the above-described process, the defective CD 22 dropped from the clamp is directly put into the defective CD box from the operation chute 70. Such defective CD processing works similarly in the case of recording failure or the like that is expected during the recording of the CD writer 50.

In addition, in the CD writer 50, when the entered CD 22 is normal, the driving motor 77 is operated to rotate the operation chute 70 to maintain the normal position. Here, the control of the normal position and the defective position of the operation chute is made possible by the limit switches S3 and S4 for detecting the rotation of the drive motor 77 at a predetermined position.

As described above, the CD ejection apparatus according to the present invention stably aligns the CD input from the magazine and at the same time determines the defect in the CD writer 50, and discharges the CD by continuously discharging it through the discharge chute. The structure is simple and can be made compact overall, and has the effect of reducing the manufacturing cost.
