2. Description of the Related Art As an on-vehicle electronic device, a magazine in which a plurality of discs are stored is loaded in an apparatus body, and one of the disks in the magazine is selected and driven in the apparatus body. There is a changer type disk device. As this disc device, the device body is installed in the space under the seat or in the space in the trunk room, and is operated by the operating device installed in the instrument panel, or is embedded in the instrument panel and used. There is something.

In this type of disc device, the opening is generally closed by a lid in a state where the magazine is completely inserted into the device body through the opening of the device body.

However, since disks such as CDs and DVDs have fixed diameters, there is a limit to how small the magazine can be made, and a mechanism for selecting disks in the apparatus and a disk drive are provided in the main body of the apparatus. Since a mechanism is required, in the disk device in which the magazine is completely housed in the device body, the device body must be large.

Further, in the disk device in which the magazine is completely stored, when the magazine is projected from the main body of the device,
Since the movement stroke of the magazine when it is extended becomes long, a large-scale magazine eject mechanism provided in the main body of the apparatus is required. In particular, when the apparatus body is installed in the interior of an automobile with the opening facing upward, the magazine must be moved upward in a long stroke against the weight of the magazine containing a plurality of discs. Therefore, it is necessary to set a large driving force or spring force of the magazine eject mechanism, which further complicates the structure.

Therefore, if only a part of the magazine is inserted into the device and the rear part of the magazine projects from the opening of the device body, the device body can be downsized and the internal magazine eject mechanism is simple. become. Further, it is suitable as a device in which the opening is installed upward in the vehicle compartment.

FIG. 6 is a partial cross-sectional view showing an example of the structure of the disk device loaded in the main body of the apparatus with the magazine partially protruding. In this conventional example, the case where the opening of the apparatus main body is installed facing upward is shown.

In this disc device 50, an opening 52 is formed in the front surface of a case 51, and the case 51 is provided with a lid 53 capable of closing the opening 52. Inside the case 51, one end of the lid 53 has a shaft 54.
Is rotatably supported by the case 51, and the lid 53 can be opened inward of the case 51.
The shaft 54 is provided with a biasing member by a torsion coil spring (not shown), and the lid 53 is always biased in a direction to close the opening 52 from the inside. At this time, the tip portion 53a of the lid body 53 contacts the edge portion of the opening portion 52 inside the case 51 so that the closed posture can be maintained.

The magazine 60 is pushed from the outside so as to hit the lid 53, and the magazine 60 is completely loaded with the rear end 60a thereof protruding from the opening 52 of the case 51 as shown by the alternate long and short dash line. When the magazine 60 is loaded, the lid 53 uses the shaft 54 as a fulcrum and the reference numeral 53j.
The magazine 60 is housed inside the case 51 by rotating to the position indicated by. At this time, the lid 53 is held in a state of being rotated inward of the case 51. Then, when the magazine 60 is projected from the opening 52 by the eject mechanism in the case 51 and the magazine 60 is further pulled out from the case 51, the lid body 53 is closed by the biasing force.

[0010]

However, in the disk device 50 shown in FIG. 6, the magazine 60 is loaded in the case 51 and the opening 52 is closed by the magazine 60. A gap is formed between 60 and the opening 52, and the degree of internal sealing is reduced.

Further, when the magazine 60 is not mounted, the lid 53 is biased by a spring in a closed state. At this time, a hand or a foreign matter is pushed into the opening 52 from the outside. Then, the lid 53 is inadvertently released inward by the force at that time. In addition, as shown in FIG. 6, when the opening 52 is installed upward, if the object is accidentally dropped from above, the lid 53 is opened and the object is placed inside the case 51. Intrusion, case 51
There is a risk of damaging internal mechanisms.

If the biasing force of the spring for maintaining the lid 53 in the closed position is increased so that the lid 53 is not opened accidentally, the magazine 60 is opened from the opening 52 to the case 51.
When it is inserted into the inside, the resistance force becomes too large, which makes it difficult to mount the magazine 60. Alternatively, the lid 53 may be damaged by the force of inserting the magazine 60.

Although it is conceivable to provide a slide type lid at the opening portion 52 of the case 51, when the slide type lid is provided, in order to secure a slide area of the lid, as shown in FIG. It is necessary to increase the size of the main body of the device in the direction orthogonal to the paper surface, which increases the width of the device.

The present invention is to solve the above-mentioned conventional problems, and the magazine is loaded with a part of the magazine protruding from the main body of the apparatus, so that the opening can be surely closed.
Another object of the present invention is to provide a magazine loading type recording medium driving device having a simple structure.

[0015]

According to the present invention, an opening is formed in the front surface of an apparatus main body having a recording medium driving unit therein, and a magazine containing a recording medium is formed in the apparatus main body from the opening. In a recording medium driving device to be mounted, when the magazine is mounted in the device body, a part of the magazine protrudes from the front surface, and the device body is closed by covering the opening. A lid that rotates between an attitude and an open attitude that opens the opening away from the opening is provided, and the lid adheres to the front surface in the closed attitude, A recess for accommodating a part of the magazine protruding from the opening is formed inside the body.

In the present invention, when the front surface of the main body of the apparatus is covered with the lid, a part of the magazine protruding from the opening of the main body is housed in the lid, so that it is not necessary to enlarge the entire apparatus. Further, since the lid body is rotated in the direction away from the front surface to be in the open posture, the lid body is not pushed in unexpectedly and opened.

For example, the outer surface of the lid has a convex shape corresponding to the concave portion. If the outer surface of the lid is formed in a convex shape corresponding to the recess, the volume of the protrusion of the lid to the front can be minimized, and the external space in front of the main body of the apparatus can be widely used.

Further, the apparatus main body may be installed inside a vehicle with the front surface thereof facing upward.

When the apparatus main body is facing upward, even if a fallen object from above hits the lid, the lid is not opened accidentally, and a part of the magazine projects upward from the opening. The process of lifting the magazine at the time of ejecting is also short, and the eject load can be reduced.

The recording medium driving device of the present invention may be installed so that the opening faces the horizontal direction.
