That is, the storage case c31) has elasticity, and the rear part of the inner case (31a), which is opened in the forward direction, is closed at the rear.4. The inner case (31a) is fitted with a wire (31) in the front half of the inner case (31a).On the bottom side of the front half of the inner case (31a) A notched recess (33, 1) is formed in which at least the center hole d of the disk D is exposed in the outward direction from the front edge, and a notch (33, 1) is formed in the upper surface side, approximately at the center of the disk D with respect to the center hole d of the disk D. A locking piece o1) that is locked in the ejecting direction is formed with a cut, and on both sides sandwiching this locking piece c34) are =l-ql pieces (35) of the disk D that is elastically biased inward. ) (35'), four engaging parts (3G+ (36')) of the lid 021, and an engaging convex part (37+ (37') that is engaged with the insertion slot frame (2) of the player (1) described above) are formed. In addition, the mouth edge of the outer case (31b) is formed with an incorrect insertion prevention part (38) corresponding to the shape of the front peripheral surface of the insertion slot frame (2). A step portion (31) corresponding to the mouth edge of the outer case (31b) is formed at the edge.

Next, the loading and unloading operations of discs stored in the storage case into the disc player configured as described above will be explained.

First, remove the lid 0 from the disc storage case Gυ, and insert a part of the disc D into the insertion slot frame (2+) at the opening of the player (1), exposing a part of the disc D (in this example, approximately half the circumference), and then insert the disc D into the insertion slot frame (2+). The opening/closing lid (6) of the opening/closing lid device (5) abuts against it and presses it inward.For this reason, the opening/closing lid (6) is rotated a little using the shaft at the upper edge as a fulcrum. The lock plate of the lock mechanism (8) that is engaged with the opening/closing lid (6) as it rotates (IZ is the substrate
It is swung to the ll side. Due to the rocking of this lock' plate (12), the leaf switch of the switch SL is turned on, the plunger prisoner is operated, the operation plate @ is slid, and this lower edge (2

Press it so that it rides on both levers CI! 11 (2
1')"K swing downward.

Due to the swinging of both levers (21J (21')), the lock plate O2 is pushed down through the engagement piece (131 (13') at the lower edge) against the biasing force of the coil spring 0CJ (19'). , the engagement with the opening/closing lid (6) is released and the opening/closing lid (6) is allowed to rotate for opening/closing (see Fig. 5).
・. The operation plate C1, 3+ is further slid by the subsequent stroke of the plunger (c), so that the push piece (23
d) presses the contact piece (27a) of the lid opening lever + 27), rotates the lid opening lever (271), and the lid opening shaft installed at the tip pushes the opening/closing lid (6) from the front side. The disk D is rotated upward (see FIG. 6) to open the insertion opening, that is, the inner opening (3) of the insertion port frame (21), and as shown in FIG. ) can be inserted into the player (11) through the inner opening 13) of the player (11).

In this state, the lock plate (121 is the protrusion of the operation plate (to)
230) (23C') separates from the engaging pin +23 (22') of lever (2+) (21'), and lever (2]) (
21') is not swung, the push-down is released and it is raised by the biasing force of the spring (1!It (19')) and is returned to swing forward, so the leaf switch SQ of switch S1 is turned off. However, the relay switch Sr connected in parallel with this remains on, the plunger (25) operates, and the switch (6) is held in the open state.

Then, when the disk D inserted from the insertion slot frame (2) is supported by the disk loading mechanism (c), the loading arm (1ξ;) operates and the disk D is pulled out from the case C3B. (It is moved horizontally while moving. This i
The case (31) has a mouth edge 1. When the inner case (31a) is fitted into the insertion port frame (2), the slope of the -j=Ehit11111 plane (3a) (3b) of the inner port (3) is 4.
Since the upper and lower surfaces of the inner opening 131 bulge in accordance with the shape of the upper and lower Ri (3c) (3d), the locking single head of the disc D is engaged with the center hole d. As the combination is released, the upper and lower prices are raised as a whole, and the disk can be easily removed.

In this way, the disk D is moved horizontally, and when this movement is completed, it is removed by the switch S2, and this switch S2 turns off the circuit of the Granger (25), making the Granger (C) inactive. At the same time as switching the disk Di
Lower the disc and place it on the table. At this time, by switching the plunger (25) to non-operation, the operation plate c! 3) returns, and in order to release the suppressed rotation of the lid opening lever (271), the opening/closing lid (6) is rotated downward in the closing direction as the operation plate (23) returns, and the lower edge When the lock plate (23+) is raised and returned to its original position, it will come into contact with the rear side of the upper edge of the lock plate (121). Projection (23C) (
23g) is pressed through the engaging pin t2Z (22') to swing the date plate (121) downward, and the opening/closing lid (6) is rotated to the front beyond the lock &021Y.In this state, Lock plate ([21 is the operation plate (231-2)
The protrusions (23b) (23g) are levers (2]) (21')
By passing the engagement pin (221 (22')), the push-down is released and it rises again, and the engagement step (12a) at the upper r = opens and closes - i'', 1 (engages with the lower edge of 610 and lock it.

On the other hand, the disk D placed on the disk cheaply
is suppressed and held by a disk clamp provided on a disk clamp arm. By holding this suppression, the switch S3 is switched to the alarm circuit (29+11!11), and the alarm means lamp or buzzer is activated to prevent the loading of the disk D into a heavy bale.At this time, the switch 82°S3 is turned off. Press the switch (6) to close the lock plate (
The plunger (25) is not operated even in the case of a suite SI pion after 12 hours and the lock plate (12+) holds the opening/closing lid (6) in a locked state.

When the disc D is played by the above operation and the disc D is ejected from this player, when the eject operation is performed, the eject switch S4 is turned on and the plunger (c) is operated from 7 to open and close the lid in the same manner as described above. (6)
is opened.

In this state, the disc D is lifted from the disc table and braked (1) by the disc loading mechanism C8I.
), that is, unloaded, and inserted into the inner opening (3) of the insertion port frame (21) from the inside,
In this case, if the inner case (31a) of the storage case mark (marked) is inserted into the insertion slot frame (2), the disk D will be inserted into this storage case (3υ), and unloading will be completed in this way. At this point, the unloading completion detection switch S5 is turned off and the plunger (29) becomes inactive, so that the fjiF closing lid (6) is closed.

Furthermore, even if the rear end of the disc D is caught between the opening/closing lid (6) and the lock plate [+21] due to a timing shift in the closing M'IJh operation, the opening/closing lid (6) will only come into contact with the disc D due to its own weight. In addition, since the upper edge end face of the lock root is in a concave shape, it will not damage the disc recording surface just by applying force to the periphery of the disc D.

In addition, in this example, disk D is stored in the storage case (31).
The disc is loaded into the player (1) with approximately half its circumference stored in the storage case 6υ.
Of course, it can be taken out and loaded from the insertion port frame (2), and since the upper and lower inner surfaces of the inner opening (3) of the insertion port frame (2) are shaped to bulge up and down, the peripheral edge of the disk D slides into contact with the insertion port frame (2). (It will not cause any damage to the disc recording surface.

Application Example The present invention can be applied not only to a disc player mounted on a vehicle, but also to a portable disc player for use in a bathroom, a recording/reproducing device for a disc-shaped magnetic recording medium, and the like.

Effects of the Invention As described above, according to the present invention, the opening/closing lid rotatably supported by the disc insertion opening of the disc player is locked in the closed state by the locking device 4'WJ and the opening/closing control mechanism, and the disc The structure is such that the lid is unlocked and opened with the insertion action during loading, and closed and locked with the ejection action, making it extremely easy to load and eject discs into the player with just one hand holding the disc. In addition, the disc insertion opening is closed and locked by an opening/closing lid except when loading or ejecting discs.This prevents double insertion of discs and also prevents unnecessary insertion of fingers, etc. Moreover, it also prevents dust from entering.
- It is possible to extend the life of the internal mechanism of the player, and it is extremely effective not only in terms of handling but also in terms of functionality, especially as a disc player mounted on an automobile or the like.
