Description

BACKGROUND THE INVENTION

(a) Scope of the invention

The The present invention provides an improvement of a memory card with two interfaces, in particular such a memory card, which serves for data access and several types of interfaces combines.

(b) Description of the Conventional embodiment

digital Memory devices such as memory cards and flash memory are among the Backrests, the one computer user often with you. Compared to floppy disks are memory cards and Flash memory smaller, but have a much larger capacity and allow quick access; In addition, these two storage devices better protected as floppy disks from moisture and destruction and allow quick access as well as fast data entry.

Flash memory are with USB as a transmission interface equipped. Since flash memory advantageously only by plugging used immediately can be and on most operating systems, no installation drivers need, They are among the indispensable accessories for computers and its peripheral products become. Advantageously, therefore, the flash memories are using easy to install from USB, for To use the user quickly, easy to handle and inexpensive.

There Digital peripheral products only with a specific memory card are memory cards, in contrast to the flash memory made in various shapes or dimensions (e.g., Smart Media Card, Secure Digital Card, Multi Media Card, Micro SD Card, Mini SD Card, Memory Stick Card, DF Card, XD Card ...) to the different Types and brands of digital devices such as digital cameras, handheld players, MP3 players, PDAs and cell phones correspond to. As the size of the various memory cards is different, and each memory card then only for the appropriate interface memory cards are usually not replaceable. Therefore, the Consumers when buying memory cards often with the problem of not given match faced with the dimensions.

• 1. Aufgrund der unterschiedlichen Dicke der Speicherkarte und des USB-Mediums ist die äußerliche Form der Speicherkarte nicht eben. Beim Einstecken in die Schnittstelle hakt die Speicherkarte leicht in das leitfähige Ende innerhalb der Schnittstelle ein, was zur Verformung des Endes führt. Dadurch wird die Stabilität beim Einstecken und Verbinden der Speicherkarte in erheblichem Maße beeinträchtigt.
• 2. Bei den herkömmlichen Speicherkarten mit zwei Schnittstellen erscheint der Kontakt (I/O) am USB außerhalb der Speicherkarte und wird beim Einstecken der Speicherkarte in ein digitales Peripheriegerät und beim Herausziehen der Speicherkarte aus einem digitalen Peripheriegerät vom menschlichen Körper berührt, so daß der Kontakt (I/O) leicht erodiert, was die Übertragung erschwert.

To solve the above problem, operators have provided a data access storage device that is equipped with both a USB and a memory card interface (the size of the memory card interface may be Secure Digital Card, CF Card, etc.). However, in this embodiment, there are still the following disadvantages, even if a data transmission through the two interfaces is possible:

• 1. Due to the different thickness of the memory card and the USB media, the external shape of the memory card is not even. When inserted into the interface, the memory card easily hooks into the conductive end within the interface, resulting in the deformation of the end. As a result, the stability during insertion and connection of the memory card is significantly impaired.
• 2. In conventional two-interface memory cards, the contact (I / O) on the USB appears outside the memory card and is touched by the human body when the memory card is inserted into a digital peripheral device and the memory card is removed from a digital peripheral device (I / O) erodes slightly, which makes transfer difficult.

in view of the recoverability of the o.g. The inventor has problems with the possibilities of improvement and finally brought about the present invention.

SUMMARY THE INVENTION

Of the The invention is therefore based on the essential task of a memory card for data access with an interface corresponding to the USB and a memory card Schnitttstelle to provide, without the Thickness as well as affect the appearance of the memory card.

The second object of the invention is to provide a memory card for To provide data access in which the USB interface is less common from the human body touched so that the Interface does not erode quickly due to contact with sweat.
