As a result, the first pressure applied by the first card C1 to the first terminal 154 is also relatively weak, so that the third round portion 154d of the first terminal 154 is lowered by the first thickness, The fourth round portion 154e is slid downward to abut the first pressure while being in contact with the sliding guide portion 132a.

14, the first card C1-a received in the first card receiving portion 212 of the tray 200 has a second thickness (h1) that is relatively thicker than the first thickness h1 (h2). As a result, the second pressure applied to the first terminal 154 by the first card C1-a is also relatively stronger than the first pressure, and the third round portion 154d of the first terminal 154 And the fourth round portion 154e is further slid downward by a predetermined length d so as to cancel the second pressure while being in contact with the sliding guide portion 132a.

As described above, when a difference in the pressure applied to the first terminal 154 due to the thickness of the first card (C1, C1-a) applied to the tray 200 is generated, the sliding guide portion 132a The first terminal 154 can press the card with the same pressure irrespective of the thickness of the first card C1 and C1-a so that the first terminal 154 Can be brought into electrical contact with the first cards C1 and C1-a having various thicknesses while maintaining the reliability of contact with the first cards C1 and C1-a.

Since the tip of the first terminal 154, that is, the fourth round portion 154e, is rounded, the tip of the first terminal 154 is slid smoothly along the sliding guide portion 132a.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It should be understood that the technical idea belonging to the scope of the claims also belongs to the present invention.
