DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a process in which a record case containing a recording medium (record) is expanded and inserted into a device [1].

The present invention relates to a recording disk reproducing device that performs ejection.

The conventional FJL configuration and its problems FIGS. 1 to 3 show the JM configuration of a record case that can be used in the recording disc playback device according to the present invention. Consisting of a main body (2) (hereinafter referred to as the case) and a lid (3) that is removably connected to an opening (7) provided on the front side of the case (2) in the insertion direction (XI) into the device. The case (2) and lid (3) are molded from styrene resin.

Case (2) consists of a pair of half-sleeves (4
), and the interior is a flat record storage space (5) spanning the entire width and length (the height is record (6)).
A record (6) (recording medium) is stored in this space (5). This sky 111J
(57 has an opening (7) on the CXJ side in the insertion direction, and the remaining three sides are closed. Each component of the case (2) has an arrow mark (XJ) centered on the center line (1) in the insertion direction. Identical components are located at diametrically opposite positions when viewed in the force direction.

Each half (4) has a recess a that plays a hinge role during expansion.
It consists of a flat plate part (8) having η on the left and right, and a protrusion part (9) along this three-sided edge. Figure 1 middle bottom 991
Looking at the half body (4), we find that the flat plate part (opening of 81 (
7) Windows (2) on the left and right near the sides that are engaged by expansion arms (described later)
At the same time, a retaining hole 0 is formed in the center near the first opening (7), into which a convex portion of the lid, which will be described later, is retained. Furthermore, the edge of the opening (7) [ζ] is formed with a pair of symmetrically tapered portions 04. This is to guide insertion of the latching mechanism, which will be described later, into the vagina. Also, in the back there is a center m
(J)) The records (6) are placed in positions shifted to the right and left.
) is formed with a protruding part OQ that comes into contact with it. Further, on the inner surface near the opening of the protruding portion (9) OO, there are provided four portions aQ with which a protrusion of the lid (3), which will be described later, engages. The half body (4) formed in this manner is adhered to the entire circumference or a part of the protrusion (9) θ0 (b) to form the case (2) with a 6° angle.

The end of the lid (3) is provided with a flange portion that closes the opening (7) of the case (2) when the lid (3) is fully fixed to the case (2). Symmetrically about the center line (71), there is a notch (tS) into which the expansion arm (described later) can enter.
A guide #4 is formed on both sides, and has a sloped part for guiding a disc holding arm in a playback device, which will be described later, and a thin part 4 that is thinner than the glue guard of record (0).
) are formed on both sides of the convex portion that engages with the hole αJ of the case (2). Also, the lid (3) is attached to the case (
2) is provided on the inclined part to serve as a guide when entering the case (2) and on the tapered part), and a protrusion f241 that engages with the aforementioned recess αQ and fixes the lid (3) to the case (2) is provided. %
It is provided on the arm □□□ that utilizes the readability of resin, and the tip thereof is provided with a sloped part that engages with the release member of the lid (3).

The second case (1) is the record (6) and the lid (3).
), and to explain this state with reference to the first cause, the record (6) comes into contact with the protrusion () and is locked in the depth direction, and the record (6) is locked in the depth direction. Retained by protrusion (9) On. Lid (:i) Iti
, the protrusion (2) engages with the recess αQ, and the protrusion engages with the hole, thereby closing and coupling the opening (7).

As a result, the record (6) is regulated by the circular arc of the lid (3) in the insertion direction (X,), and is stored without falling out of the case (2). The thickness of the part of the Dentetsu (3) that enters the case (2) is approximately the same thickness as the storage space of the case (27) (5J), and the record (6) will not fall out from that gap.

The operation follows the same steps as described above, but here, in order to particularly clarify the problems that occur in the conventional example, the steps (f) will be explained one after the other.

No. 5121 (A1i-j: Case (2) is the expansion mechanism
This figure shows the state before contact with the object. From this state, the case (2) expands as shown by the arrow (E) m 41
(J is in contact with l1ll, and the beam compensation η is at the tapered part - (
(see Figure 4) rotates in the direction of the arrow (1").
Expanding the case (2) Figure 5 (b) shows the state in the middle of expansion.

In other words, the roller Ill in FIG. 4 is located at the middle of the tapered bag. In this state, there is still a case (
The protrusions (57a) and (58a) in the hole α of 2) are not fully locked. However, since the roller Ill is located in the middle of the tapered portion, it can be returned to the state of (a) by the action of the coil spring or the like described in 01.

Next, the expansion progresses and the fully expanded state is shown in FIG. 6(c). In this state, the hole (
2) has protrusions (57a) and (58a) in a locking manner.

When used by a normal user, the expansion mechanism operates as shown in FIGS. 5(a), 5(b), and 5(c) above. 1, when removing the case (2), use the expander 4741.

The expansion mechanism Ill operates in the following order: → (c), (c) → (b) → ('r). In such an operation, since the expanding mechanism ψυ has a certain degree of inertia, the impact when the case (2) comes into contact with the expanding mechanism Ill prevents the expanding mechanism 1iI ), and as shown in Figure 5 ej, it is completely case (2).
The hole 03 and the protrusion (57a) (58a) are not engaged, resulting in the state shown in FIG. Lost, Casek 2
) is near the insertion slot, the expander 4
74111 is located inside the playback device.

In this state, since the roller 1 is completely above the tapered part β4, the expansion 'BM)'il'
b'J cannot return to the vicinity of the insertion port M due to the force of the aforementioned coil spring or the like. In this state,
Case (2) f: It is impossible to suppress the expansion mechanism ←υ again and make it operate normally! , 11 In order to return to normal condition, the playback device must be disassembled and repaired. In other words, once an abnormal situation like the one described above occurs, the user will not be able to return to a normal state and will not be able to play the record.Although it may not happen, once it occurs, it will cause a major failure, so it is not reliable. This is a problem that must be resolved in order to improve performance.

Furthermore, since there is little wobbling, the record case (1) can be inserted smoothly.

The above is an explanation of the embodiment of the expansion mff4 according to the present invention, but the configuration and operation of the other parts 114 of the reproduction device I11 are completely the same as those of the conventional example described above.

Effects of the Invention As described above, according to the present invention, after the case is expanded, the case advances to a predetermined position and the expansion mechanism can only move when the latch locks the case. Therefore, there is no problem such as in the conventional example where the case and the expansion mechanism are damaged due to severe use by the user and the expansion mechanism runs alone. Furthermore, the configuration of parts is simpler than in the conventional example. Finally, according to the present invention, the reliability of the playback device itself can be made perfect, and the structure is simple, so it is suitable for mass production.
