Abstract

A computer-dedicated auxiliary data access device comprised of a device case having a minimum of one horizontal slot in the front side and, furthermore, a housing cavity perpendicularly formed inward beyond the horizontal slot, a universal serial bus interface socket installed at the end section of the housing cavity, an IC circuit board disposed in parallel alignment with the horizontal slot, a card terminal connector respectively situated at the end face of the IC circuit board, and a number of perpendicularly supportive spring contacts of the card terminal connector that are connected via a flat cable routed to the interface socket. The horizontal slot provides for the sideways insertion of an ultra thin flat memory card, with the memory card internally consisting of high-speed flash memory chips and also including a main controller IC and a memory IC which have a read/write specification of 10,000 times to enable the rapid reading and writing of data. An exposed read access area is formed in the top of memory card that is in parallel alignment with the card terminal connector, the read access area consisting of an elastically loaded plurality of contacts intervallicly disposed that enable perpendicular mutual engagement. A transmission cable is installed to interface socket and the other end is installed to the USB port of a computer. As such, the present invention achieves computer-dedicated high speed and high capacity auxiliary memory access operations, while providing for convenient portability.

Claims

1. A computer-dedicated auxiliary data access device comprised of a device case having a minimum of one horizontal slot in the front side and, furthermore, a housing cavity perpendicularly formed inward beyond the said horizontal slot, a universal serial bus (USB) interface socket installed at the end section of the said housing cavity, an IC circuit board disposed in parallel alignment with the said horizontal slot, a card terminal connector respectively situated at the end face of the said IC circuit board, and a number of perpendicularly supportive spring contacts of said card terminal connector that are connected via a flat cable routed to the said interface socket;

the said horizontal slot provides for the sideways insertion of an ultra thin flat memory card;

the said memory card internally consists of high-speed flash memory chips and also includes a main controller IC and a memory IC which have a read/write specification of 10,000 times to enable the rapid reading and writing of data;

an exposed read access area is formed in the top of the said memory card that is in parallel alignment with the said card terminal connector, the said read access area consisting of an elastically loaded plurality of contacts intervallicly disposed that enable perpendicular mutual engagement;

a transmission cable is installed to said interface socket and the other end is installed to the USB port of a computer;

as such, the present invention achieves computer-dedicated high speed and high capacity auxiliary memory access operations, while providing for convenient portability and maintenance.

2. As mentioned in claim 1 of the computer-dedicated auxiliary data access device of the invention herein, an arresting element projects horizontally from bottom side of the said housing cavity, limiting further inward movement of the sideways and perpendicularly inserted said memory card.

3. As mentioned in claim 1 of the computer-dedicated auxiliary data access device of the invention herein, the optimal dimensions of the width of the said horizontal slot and the depth of the said housing cavity perpendicularly formed inward is 5.4 cm and 8 cm, respectively, and a locating plate is spread over the upper extent.
