Since electronic memory cards only provide direct data circulation for supported digital products, for various electronic devices, such as personal desktop computers, notebook computers, industrial computers, personal digital assistants PDA, mobile phones or digital cameras, etc. , it is necessary to use various types of memory card data reading devices, also known as card readers, silicon disk drives, transfer cards or memory card slots, to achieve the circulation of the two data, and these memory card data reading devices The device is divided into two types, one is a data reading device with a single specification, and the other is a data reading device with multiple specifications. Convenience, so most of the memory card data retrieval devices are set in the form of a memory card slot, and combined with the circuit board, so that users can directly insert the memory card into the memory card slot in the electronic device for use;

When the above-mentioned two types of memory card slots are in use, there are still the following problems that need to be improved:

1. The memory card slot is usually designed to only be suitable for a memory card of a single specification;

2. If the memory card slot is set, memory cards of multiple specifications can be used, and most of them are set in a multi-slot style. This design not only makes the reading device bulky and difficult to carry, but also relatively increases the cost;

3. If the data reading device is a multi-standard reading type, it cannot be designed to be able to apply the newly released M2 memory card or MS-DUO memory card and other small memory cards with later specifications.
