Field of the Invention The present invention has a recording / reproducing device having an opening used for inserting or ejecting a recording medium, and performing recording / reproducing by moving the recording medium to a recording / reproducing position after completion of insertion of the recording medium. The present invention relates to a lid opening / closing device for a lid that is used in an apparatus and blocks the recording / reproducing unit from the outside of the recording / reproducing apparatus by closing the opening from the back side.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 12, for example, a recording medium insertion opening 101b used for inserting / ejecting a recording medium 2 in a cartridge shape and a lid 102 for covering the recording medium insertion opening 101b are provided on the side surface. In the disc driver provided in the reproducing device or the like, opening and closing of the lid body 102
The recording medium insertion opening 101 is controlled by the lid opening / closing device.
It prevents dust and the like from entering the inside of b.

The structure of such a lid opening / closing device will be described below with reference to FIG.

As shown in FIG. 13A, the lid opening / closing device is a recording medium provided at a position deeper than a recording medium insertion portion 101a provided on the front surface of a cabinet 101 which is an exterior body of a disk driver. A lid 102 that closes the insertion opening 101b from the back side, and a spring (not shown) that urges the lid 102 so that the recording medium insertion opening 101b is closed except when the recording medium 2 is inserted or ejected. Is equipped with.

Further, the lid body 102 includes a lid portion 102a,
The lid 102a is provided with a support shaft 102b provided at both ends in the longitudinal direction of the top wall. Further, a protrusion 102c with which the recording medium 2 contacts when the recording medium 2 is inserted is provided on the front surface of the lid 102a.

Then, the support shaft 102b is engaged with an engagement portion (not shown) of the disk driver main body, so that the lid portion 102a is pivotally supported in the cabinet 101 about the support shaft 102b. In addition, before the insertion of the recording medium 2 or after the completion of the insertion (normal state), the recording medium insertion port 101b is kept closed.

When the recording medium 2 is horizontally inserted from the recording medium insertion opening 101b in the F direction from the above-mentioned normal state, first, the recording medium front end portion 2a is projected on the projection portion 102 of the lid portion 102a.
abut on c. When the recording medium 2 is further inserted from this state, the lid portion 102a starts to rotate about the support shaft 102b in the X direction which is the direction of opening the recording medium insertion opening 101b. Then, the protrusion 102c starts sliding on the recording medium upper portion 2b, and the recording medium 2 pushes up the lid portion 102a in the X direction and passes through.

In this way, when the user pushes the recording medium 2 to the recording medium insertion opening 101b with his / her finger or the like, the recording medium 2 becomes a disc driver main body as shown in FIG. 13 (b). By a mounting mechanism such as a loading device (not shown) of the mechanism 103 provided in the cabinet 103, the cabinet 101 is vertically lowered in the bottom wall direction, that is, in the D direction,
It is inserted in the recordable / reproducible position.

At this time, the lid 102 is urged by a spring (not shown) so that the recording medium insertion opening 101b is closed. Therefore, when the recording medium 2 moves in the D direction, the cover portion 102a contacts the recording medium 2 inserted at the recording / reproducing position until the support shaft 102 is supported.
It rotates about b in the Y direction, which is the direction of closing the recording medium insertion opening 101b. That is, when the recording medium 2 is at the recording / reproducing position, the lid portion 102a has an upper portion 2b of the recording medium.
Is kept in contact with.

On the other hand, when the recording medium 2 is ejected from the disc driver, first, the recording medium 2 is moved to the mechanism 1.
A mounting mechanism such as a loading device (not shown) 03 raises the cabinet 101 vertically to the ceiling wall direction, that is, the C direction. At this time, the lid 102 is pushed up again in the X direction as the recording medium 2 rises in the C direction.

After the recording medium 2 is completely lifted, the mechanism 103 is pushed with the lid 102 pushed up in the X direction.
By the mounting mechanism such as a loading device (not shown), the recording medium 2 is slid in the E direction, which is the discharging direction, to complete the discharging.

When the user removes the discharged recording medium 2 and the recording medium 2 pushes up the lid 102 in the X direction, the lid 102 is rotated about the support shaft 102b by a biasing force of a spring (not shown). It rotates in the direction and returns to the normal state again.

[0013]

However, in the above-mentioned conventional lid opening / closing device, when the recording medium 2 is inserted into the recording / reproducing position, the lid 102 remains in contact with the upper portion 2b of the recording medium. In the normal state, that is, the recording medium insertion port 10
Since it does not return to the state of closing 1b, the recording medium insertion port 10
1b has a problem that dust, foreign matter, and the like enter.

Therefore, for example, as shown in FIG. 13 (c), the mechanism 103 is retracted in the F direction so that the recording medium insertion opening 101b does not interfere with the rotation of the lid 102.
By providing the recording medium 2 at a deeper position, it is conceivable to return the lid body 102 to the normal state when the recording medium 2 is inserted into the recording / reproducing position.

However, when inserting the recording medium 2 into the disk driver, the user can push the recording medium 2 with the finger only up to the recording medium insertion opening 101b.
Therefore, when the above method is used, there is a problem that the recording medium 2 cannot be inserted up to a predetermined position of the mechanism 103.

Therefore, a method of retracting the recording medium 2 to a predetermined position of the mechanism 103 by providing a case retracting member or the like may be considered. In this case, a motor for driving the case retracting member or the case retracting member is used. A transmission (conveying) member for conveying the recording medium 2 from a member or the like to the mechanism 103, or the recording medium 2 is the mechanism 103.
In this case, a case insertion detecting member or the like for detecting whether or not it has been inserted up to a predetermined position is required. Further, by lowering the mechanism 103 in the F direction, the mechanism 10
Cabinet 201 compared to before 3 is lowered in the F direction
Will be larger. Further, in order to open the recording medium insertion opening 101b when ejecting the recording medium 2, another driving device such as a motor for moving the lid 102 in the X direction is required. For this reason, there arises a problem that the manufacturing cost is high.

Further, as shown in FIG. 13 (d), the recording / reproducing position of the mechanism 103 is lowered in the D direction so as not to hinder the rotation of the lid body 102, so that the recording medium 2 is moved to the recording / reproducing position. When attached, the lid 102
It is also conceivable to restore the normal state.

However, when the recording / reproducing position is lowered in the D direction, the distance until the recording medium 2 is conveyed to the recording / reproducing position becomes long. Therefore, by lowering the recording / reproducing position in the D direction, the size of the mechanism 203 becomes larger than that before the recording / reproducing position is lowered in the D direction. Also in this case, in order to open the recording medium insertion opening 101b when ejecting the recording medium 2, another drive device such as a motor for moving the lid 102 in the X direction is required. Therefore, the size of the cabinet 301 also becomes large. This causes a problem of high manufacturing cost.

Further, in order to inform the user that the recording medium 2 has been inserted into the recording / reproducing position, the insertion of the recording medium 2 is mainly detected by a detection member, and this detection signal is detected by an electric circuit. Processing and lamps and LEDs (light emitting diodes)
The method of displaying is used. For this reason,
There is a problem that the manufacturing cost is high.

Therefore, with a simple structure, it is possible to prevent dust and foreign matter from entering the disk driver, and it is possible to easily inform the user that the recording medium has been inserted into the recording / reproducing position. A lid opening / closing device is required.

The present invention has been made in view of the above problems, and an object thereof is to completely close the insertion port by the lid even when the recording medium is inserted at the recording / reproducing position. At the same time, another object of the present invention is to provide a lid opening / closing device having a mechanism capable of easily informing the user that the recording medium has been inserted into the recording / reproducing position.
