In the initial position, the front end portion of the engagement piece 2 is retracted into the recess 25 of the side portion 5a. Therefore, the engagement state between the engagement piece 2 and the lock recess 10 1 is released, and the lock of the memory card Mc is released. Was released. Further, a large portion of the rear portion of the memory card MC is exposed from the card insertion opening 3a of the slot body 3, so that the memory card Mc can be taken out from the slot body 3. Here, the card-shaped cam groove portion 15 and the cam pin 16 constitute a slider lock mechanism in which the slider 5 is locked at a predetermined time when the push-in force to the memory card MC is released after the slider 5 is moved to the rearmost position. Position, after the lock, a pushing force is applied to the memory card MC, and the lock is released when the slider 5 moves rearward. In the memory card slot of the present embodiment, only one of the upper and lower metal shells (the bottom case j and the cover 2) is press-fitted and fixed to the base 7' of the contact block 4 by laser The welding joins the other shell 2 to the joint with the bottom shell I; the bottom shell 1 is not subjected to further pressing and fixing the casing 2 on the base 7 as pressed and fixed to the bottom casing The force of pressing the casing 2 into the base body 7 132164.doc -23· Ϊ 374580, so that the bottom case 1 can be prevented from being deformed. Moreover, since the casing 2 is not pressed in and fixed to the base body 7, the casing 2 is not subjected to the shock force generated by the positional displacement of the press-in portion when it is pressed in, and the casing 2 can be prevented. As a result, deformation of the socket body 3 can be suppressed, thereby improving the flatness of the socket body 3. In addition, the cover 2 is not directly fixed to the base 7 of the contact block 4, and the bent piece 19 provided at the rear end of the cover 2 abuts against the engaging recess 18 provided on the rear side of the base 7 from the rear, and The protruding piece 20 provided on the slightly more front end side of the curved piece 19 abuts against the engaging recessed portion 17 provided on the front side of the base body 7 from the front. Therefore, when the suffix card MC is taken out, the force generated by pushing the substrate 7 forward is generated by the frictional force generated between the I/O contact surface of the memory card MC and the contact point 10, and at this time, the cover The protruding piece 20 of 2 receives a force for pressing the upper portion of the base 7 forward, whereby the base 7 can be prevented from falling backward. Moreover, when the memory card MC is inserted, the force which pushes the base 7 rearward is also generated by the frictional force generated between the I/O contact surface of the memory card Mc and the contact point 10, and the bent piece of the cover 2 The 19 is biased by pushing the upper portion of the base 7 rearward, thereby suppressing the base 7 from falling backward. Further, only the left and right side portions of the casing 2 are welded to the bottom case 1, so that the strength of the central portion is weakened, but the trailing edge and the ridge fold of the cover 2 are formed with the downwardly projecting curved piece 1 9, and thus The bent piece 19 can increase the strength of the cover 2. Further, in the present embodiment, the joint portion of the metal bottom case 1 and the cover 2 is joined by laser splicing, so that the potentials of the bottom case 1 and the case 2 are completely the same, and The bottom case 丨 is grounded, so that the entire socket body 3 is reliably grounded, so that antistatic and external noise can be better, and I32164.doc -24 - 1374580 can be improved. In this embodiment, The base 7 of the contact block 4 is press-fitted and fixed to the bottom case 1, and the cover 2 and the bottom case 1 are joined by laser welding, but may be disposed opposite to the surface and the back of the memory card MC, respectively.
