First, referring to FIG. 6 to FIG. 9 , when the optical disk drive 1 extends from the opening 220 into the accommodating space 221 along the first direction D1, the limiting elastic pieces 226 can assist the optical disk drive 1 to enter the optical disk drive 1 . The accommodation space 221 is used to limit the left and right positions of the optical disk drive 1, and the pressing portion 229 can abut against the top surface of the optical disk drive 1 to limit the upper and lower positions of the optical disk drive 1. Then, the engaging side wall 212 of the positioning member 21 is pushed against the guiding slopes 232 of the engaging protrusions 231, so that the positioning elastic piece 23 is bent in the second direction D2 when the engaging side wall 212 passes. When the inclined surface 232 is guided, the positioning elastic piece 23 is immediately reset and the engaging convex portions 231 protrude into the locking groove 213 of the positioning member 21, so that the engaging side wall 212 is received in the third direction D3. The limiting faces 233 of the engaging projections 231 are constrained so that the front and rear positions of the optical disk drive 1 are restricted. Through the above limitation manner, the positioning mechanism 2 can mount and position the optical disk drive 1 in the accommodating case 22.

Referring to FIG. 5, FIG. 10 and FIG. 11, when the engaging protrusions 231 protrude into the slot 213 of the positioning member 21, the exiting elastic piece 214 is compressed by the blocking wall 222 and accumulates. The elastic biasing force is applied to the end of the positioning elastic piece 23 near the triggering opening 230, so that the positioning elastic piece 23 is bent in the second direction D2 until the engaging convex portion 231 leaves the locking groove 213. The exiting elastic piece 214 is pressed against the blocking wall 222 by the elastic biasing force to be reset, so that the positioning member 21 and the optical disk drive 1 are withdrawn in the third direction D3, so that the optical disk drive 1 can be easily withdrawn from the capacity. The housing 22 is placed.

It is worth mentioning that the engaging protrusions 231 can also be disposed on the engaging sidewall 212, and the guiding slope 232 faces the first direction D1, and the limiting surface 233 faces the third direction D3. When the optical disk drive 1 is inserted into the accommodating space 221 by the opening 220, the positioning elastic piece 23 is pushed up by the engaging side wall 212 and displaced upward along the guiding inclined surface 232, and when the engaging side wall 212 passes the After positioning the elastic piece 23, the positioning elastic piece 23 reinses elastically into the card slot 213 to limit the displacement of the optical disk drive 1 in the third direction D3.

As shown in FIG. 4, the exiting elastic piece 214 of the embodiment is such that the engaging side wall 212 punches out a partial piece and is bent backward to be elastically deformed forward, but the implementation manner is not limited thereto. Can be replaced by a spring. In addition, the engaging convex portion 231 of the present embodiment is formed by partially pressing and bending the positioning elastic piece 23, but in other variations, the engaging convex portion may also be formed on the engaging side wall 212, in other words, as long as positioning The height of the elastic piece 23 before the elastic deformation is lower than the height of the engaging side wall 212, and the positioning elastic piece 23 can be elastically deformed upward when the engaging side wall 212 passes the positioning elastic piece 23, and after passing through the engaging side wall 212 The elastic deformation is restored to fall into the slot 213 and is blocked by the engaging side wall 212.

In summary, the engaging protrusions 231 of the positioning member 21 are pushed against the engaging protrusions 231 of the positioning elastic piece 23, and the positioning elastic piece 23 is bent upward. At this time, the engaging protrusions 231 are extended. The positioning slot 21 is inserted into the receiving housing 22; when the disc player 1 is to be withdrawn, the positioning elastic piece 23 is bent upward to the disc housing 213.
