Ic card

Abstract

An IC card is prevented from falling off readily an electronic device while maintaining the mechanical strength of the IC card. A recess for preventing a memory card from falling off an electronic device is provided at the side of one side of a principal surface of a cap of the memory card which is configured by fitting a memory body in a recess formed on a parts mounting surface of the cap. The bottom of the recess is terminated in the middle of the thickness of the cap. This construction makes it possible to prevent the memory card from falling off readily an electronic device while maintaining the mechanical strength of the memory card.

1 - 18 . (canceled) 
   
   
       19 . An IC card comprising:
 a cap having a first surface and a second surface, which is a reverse surface thereof; and   an electronic part body secured in a first recess of the second surface of the cap,   wherein a second recess is configured to prevent the IC card from accidental disengagement from an electronic device,   the second recess is provided on one side of the cap, and   the second recess has a depth in a thickness direction of the cap such that the second recess terminates in an intermediate portion between the first and second surfaces.   
   
   
       20 . The IC card according to  claim 19 , wherein the depth of the second recess is one third to two thirds of the thickness of the cap. 
   
   
       21 . The IC card according to  claim 19 , wherein the IC card is a Reduced Size Multi-Media Card (RS-MMC) and the cap has dimensions in plan view satisfying the RS-MMC standard,
 wherein the electronic part body comprises a sealing device, a first non-volatile memory chip, and a controller chip for the first non-volatile memory chip, and   wherein the first non-volatile memory chip and the controller chip are sealed by the sealing device.   
   
   
       22 . The IC card according to  claim 21 , further comprising a second non-volatile memory chip, wherein the second non-volatile memory chip is arranged over the first non-volatile memory chip. 
   
   
       23 . The IC card according to  claim 19 , wherein the cap has a first side and a second side, the first and second sides are arranged to be parallel to a first direction in which the IC card is inserted into the electronic device, the second recess is provided in the first side of the cap, and the second side is not provided with a second recess.
