Abstract

The invention relates to a file player which can be directly connected with an USB Portable Disk, comprising an input connector, a power connector (8), a circuit board, a monitor (9) and a casing (10). The invention is characterized in that the monitor (9), a keypad (5), an USB master device connector (4), a VGA output connector (6), and the power connector (8) are arranged on the casing (10); and a CPU chip (2), a display sequential control chip (3), an USB Hub chip (1) and a memory (7) are arranged on the circuit board which is in the casing. The invention has the advantages of that the file player which can be directly connected with the USB Portable Disk can conveniently look over and play content of the USB Portable Disk, and the file player also is provided with portability and usability.

Description

technical field [0001] The invention belongs to a player, in particular to a file player which converts the content of a file in a USB mobile memory into a VGA signal and displays it. Background technique [0002] USB mobile memory has been deeply applied to various fields of our lives, and its advantages lie in its convenient and fast mobility and reliability when storing large amounts of data. But it is only used as a medium for data storage and movement. After investigation and research on the frequency and usage of USB mobile storage by ordinary users, it is found that most of the time USB mobile storage is used for copying and pasting Microsoft Word files, Microsoft PowerPoint files, picture files, sound files, and movie files. . In the process of this information exchange, if you want to view the content of the stored file, or edit the content of the file, you must rely on a computer to complete the functions of data reading, writing, and editing. That is to say, it...
