Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium exchange device of a recording / reproducing device for recording / reproducing a recording medium such as an optical disc, a magneto-optical disc, a DAT (digital audio tape recorder) tape, a DCC and a compact cassette tape. In particular, the present invention relates to a recording medium transfer device that transfers a recording medium between the recording / reproducing unit and the recording medium storage unit and between the recording medium storage unit and the recording medium insertion port.

[0002]

2. Description of the Related Art Conventionally, in a recording medium transfer device of a recording / reproducing apparatus for selecting and recording any one of a plurality of recording media such as magneto-optical disks, the disks (recording media) are manually inserted into a magazine (storage shelf). In some cases, the magazine is mounted in a recording medium exchanging device, and an arbitrary disk in the magazine is transferred to the recording / reproducing unit by a transfer device.

In this case, the disk is selected by the transfer device. That is, the disc in the magazine is placed on the tray, the hook of the transfer device that moves up and down engages with the hook of an arbitrary tray, and the hook of the transfer device pulls out the tray on which the disc is placed, and the recording / reproducing unit. Transfer to.

Further, there has been a device in which a transfer device pushes out a disk in a magazine, bites it into a feed roller, and transfers it to the recording / reproducing section by the feed roller.

[0005]

In the above-mentioned conventional recording medium transfer device, even when only one recording medium stored in the magazine is exchanged, it is necessary to take out the magazine and exchange the recording medium. There was a problem that it took time and effort.

Further, if the magazine is taken out and the disc is exchanged during the performance, the disc may be inserted into the wrong position and the space for the disc being played may be closed. Therefore, the disc exchange during the performance is prohibited.

The present invention has been made in view of the above points, and it is an object of the present invention that only one recording medium can be easily replaced and that the recording medium can be played while it is being played. Another object is to provide a recording medium transfer device for a recording / reproducing device.

[0008]

According to the recording medium transfer device of the present invention, the recording medium storage portion and the recording medium storage portion are inserted from the recording medium insertion port by the driving force of the feed roller and the movement of the pushing arm driven by the cam. The recording medium is transferred between the recording medium and the recording / reproducing unit.

Further, the recording medium transfer device of the present invention is
A recording medium is transferred between a recording medium storage section and a recording / reproducing section, each of which has a plurality of shelves having front and rear entrances and holding recording media so as to be movable, and between the recording medium storage section and the recording medium insertion slot. In the recording medium transfer device, the recording medium is guided from the outside of the moving path of the recording medium into the moving path by being guided by a feed roller and a cam that feeds the recording medium between the recording medium housing section and the recording medium insertion opening. An extruding arm that pushes into the shelf from the front entrance and pushes out from the rear entrance is arranged, and from the outside of the moving path of the recording medium guided by the feeding roller and the cam that feeds the recording medium between the recording medium storing section and the recording / reproducing section. A push-out arm for displacing the recording medium into the movement path from the rear entrance / exit of the shelf to the inside of the shelf and further extruding from the front exit / entrance is arranged.

In each of the recording medium transfer devices,
The recording medium transfer operation between the recording medium storage section and the recording / reproducing section, the recording medium transfer operation between the recording medium storage section and the recording medium insertion opening, and the recording / reproducing operation are performed independently of each other. This makes it possible to exchange the recording medium during recording and reproduction.

In each of the recording medium transfer devices,
A member for supporting the feed roller is rotatably supported, and the member is biased in the direction in which the feed roller ejects the recording medium from the recording medium insertion port.

In each of the recording medium transfer devices,
Power is transmitted from one drive source to each of the feed rollers and the pushing arm, and transmission and cutoff of power from the driving source to the pushing arm are controlled.

Further, in the recording medium transfer device,
Transmission and cutoff of power is performed by the planetary gear mechanism and braking means.

[0014]

According to the recording medium transfer device of the present invention, the recording medium held on the shelf of the recording medium storage section is pushed out from the entrance on the recording / reproducing section side by the pushing arm and is fed toward the recording / reproducing position by the feed roller. . Further, the recording medium inserted into the recording medium insertion port is sent toward the recording medium storage unit by the feed roller and then pushed into the recording medium storage unit by the pushing arm. Further, the recording medium on which recording / reproduction is finished is sent from the recording / reproducing unit to the recording medium housing unit by the feed roller, and then pushed into the recording medium housing unit by the pushing arm. Further, it is pushed out from the entrance on the recording medium insertion opening side by the pushing arm and is fed toward the recording medium insertion opening by the feed roller.

Since each of the above operations is performed independently, recording / reproduction is performed by moving the shelf of the recording medium storage unit and moving the recording medium between the recording medium storage unit and the recording medium insertion port during recording / reproduction. It is possible to replace the recording medium inside.

In addition, power is transmitted from one drive source to each of the feed rollers and the pushing arm, and transmission and cutoff of power from the driving source to the pushing arm are controlled by a planetary gear mechanism and braking means. The mechanism is simple and the manufacturing cost is low.

In addition, a member that supports the feed roller is rotatably supported, and the member is urged in the direction in which the feed roller ejects the recording medium from the recording medium insertion port. It is easy to eject the recording medium as it is largely extruded from.
