Therefore, the UIM drawer 12 is inserted through the insertion / removal opening 13a of the mounting sheet metal member 13. When the left and right cutouts 13c are moved forward and backward, the slots formed by the left and right cutouts 13c function as guide portions for guiding the movement of the UIM drawer 12, and the UIM drawer 12 is moved forward and left and right of the mounting sheet metal member 13. When the case engaging portions 12f of the two legs of the UIM drawer 12 are engaged with the one end of the notch 13c, the case engaging portions 12f Engaged tightly fit into the slot-away portion 13c is formed, thereby UIM drawer 12 is firmly supported.

  Further, the length of the UIM drawer 12 from the edge of the card abutting portion 12e that contacts the UIM card 11 to the tip of the handle portion 12b is equal to the length of the UIM card 11 in the direction corresponding to the length direction. They are substantially the same or shorter (substantially the same in the illustrated example). This is because when the UIM card 11 is pulled out, it is sufficient that only the card abutting portion 12e at one end of the UIM drawer 12 abuts the UIM card 11, and the periphery of the card as in the SIM tray of Patent Document 1 described above is sufficient. This is because the UIM drawer 12 is short because no surrounding frame is required, and when the UIM card 11 is inserted, if the UIM drawer 12 is too long, the UIM card 11 is prevented from being inserted.

  In this manner, the mounting sheet metal member 13 of the card mounting device 10 of this embodiment is mounted in the character input side housing 3 having the opening 8d for attaching and detaching the battery 8, and the card facing surface 12a of the UIM drawer 12 is mounted.
