<p>PROBLEM TO BE SOLVED: To mount a desired storage on an electronic device without changing the basic constitution of the electronic device even when a fast access or an inexpensive storage is desired by properly selecting a storage means such as an HDD, a semiconductor memory, etc., and mounting them on the electronic device. SOLUTION: A connector 2a which is connected to a mother board is prepared at one of both ends of a memory board 2, and the connectors 2b and 2c which are connected to the extension memory boards 3 and 4 are prepared at the other end of the board 2. The board 2 contains a semiconductor memory such as a flash memory, etc., mounted on a printed board. When the board 2 is mounted on a POS terminal, the connectors 2b and 2c of the board 2 are connected to the connectors 3a and 4a of the boards 3 and 4 respectively. Then, the space tubes 9 are held among the holes 2d, 3b and 4b respectively. Each tube 9 has the upper and lower screw holes and therefore is fixed to the boards 3 and 4 via screws. Thus, it is not required to prepare a new space nor new mechanism in an electronic device.</p> |
