PROBLEM TO BE SOLVED: To improve the expandability by constituting an electronic circuit module by covering a mount substrate with a cover body, and making it possible to plug and connect an extension module board to a card connection connector exposed through the cover body. SOLUTION: A desired memory module 4 after being inserted into the fitting part 30 of a connection connector 3 from obliquely above (arrow A) is pressed down (arrow B). The memory module 4 is thus pressed down and then the side edge of a cut formed in the side edge of the memory module 4 interfers with a lock part 33a and press the lock part 33a sidewards, so that it is set at a specific position. Then the lock part 33a returns to its original position to prevent the memory module 4 from falling. Thus, the memory module 4 is mounted in the card connection connector 3 and the circuit module on the memory module 4 is connected, thereby extending the memory. |
