Description

Removable memory cartridge device {FLASH MEMORY CARTRIDGE}

The present invention relates to a detachable memory cartridge device, and more particularly, a memory slot capable of accommodating flash memory cards of various types and capacities therein, and combined with an MP3 decoder device omitting memory, thereby providing an intact MP3 player. A USB connector is configured at one side to allow connection to a USB port of a computer through the USB connector in a state where a flash memory card is accommodated. The present invention relates to a removable memory cartridge device, which is advantageous in memory expansion and lowers a cost in comparison with a conventional MP3 player by manufacturing only an MP3 decoder device excluding memory.

In general, an MP3 file, which is a music file for a computer, is a file obtained by compressing and encoding audio information into a computer file by the MPEG1 LAYER3 method, as is well known.

Therefore, since such MP3 files are music files for computers, they can only be played by computers having multimedia functions until a dedicated audio playback device for them is known.

In other words, MP3 files could not be enjoyed in the past in an environment without a multimedia computer environment.

Therefore, in recent years, it is possible to enjoy MP3 files regardless of place and time by MP3 player which receives and reproduces compressed audio signal to enjoy MP3 files without using a computer.

However, these MP3 players are not widely available due to the high product price due to the internal flash memory cards. Also, since different MP3 makers use different flash memory cards, compatibility with each other is almost impossible. There is a problem.

In addition, the flash memory mounted inside the MP3 player is not guaranteed to expand compared to a high price, and the capacity of the memory used in the MP3 player cannot be easily upgraded. In such an upgrade, the existing flash memory is not reused.

The present invention has been made to solve the above problems, the purpose of which is to form a memory slot that can accommodate a flash memory card therein to be exposed to the outside and connected to the USB port of the computer device to one side This USB connector is configured to be combined with an MP3 decoder device in a state where a flash memory card of a storage device of a predetermined capacity is inserted in the device to constitute an intact MP3 player and to be a portable memory drive using the USB connector. It is to provide a removable memory cartridge device that can be utilized.
