FIELD OF THE PRESENT INVENTION 00 The new type structure of an adapter card in the present invention is particular o for the structural design and manufacturing process of a memory card in providing the storage and retrieval of the data and information.

SBACKGROUND OF THE INVENTION Going with the increasing development and progress of the science and technology, the related electronic information product such as personal computer, MP3, digital camera, video recorder with camera and so forth of multimedia product i o become very popular, and the requirement or demand for the digital storage device in application of these said multimedia product from the consumers is also increased relatively. But, the specifications, size and apparatus of these said multimedia products are different either from product model to product model or form manufacturer to manufacturer.

The digital storage devices of memory card and portable disk and so on already become the personal belongings of many computer users; Comparing with the diskette, the memory card and portable disk are not only small size, large storage capacity and quick storage/retrieval but also are hardly wetted and destroyed with quick read/write so that the memory card and portable disk become the indispensable accessory of the computer and the peripherals of the computer.

For the portable disk, the equipped transmission interface of the universal serial bus (USB), which being generally used in the common existing computers and peripherals, possesses the plug-and-play (PnP) function without installation of additional drive program to most operating systems; Thereby, such design is not only easy in installation and running for the vendors but also a way of quick and simple operation and cheap price for the users.

SUMMARY OF THE INVENTION 00 Accordingly, the main object of the present invention is to provide a memory card fabricating process of not only quick production but also increasing the quality 0 and yield.

The further object of the present invention is to provide a memory card for storage and retrieval of the data and information with not only the specification and size in dual interface of both in conforming to the universal serial bus and memory io card interface but also eliminating the risk in affecting the standard thickness and shape of the memory card.

For achieving the objects aforesaid, the new type structure of an adapter card of the present invention combines both advantage of thermosetting and thermoplastic resin so as to let the dual interface adapter card of memory card and the USS have not only high production speed and yield but also easy assembly and better elasticity of flexibility without deformation or distolrtion and fracture; Additionally, by means of the contrivance in demountable separable block of temporal removal form or stacking on the universal serial bus (USB), the memory card can be made to have the shape and size of memory card or conform to the application specification of the USB.
