Abstract
The utility model provides an all-in-one card reader provided with a USB HUB, which belongs to a read/write device of a portable memory device and comprises a USB input port, a reader module and a USB HUB module, wherein the reader module comprises a reader chip, an SD/MMC card slot, an XD card slot, an MS/MSPro card slot, a CF/MD card slot and a TF/Micro SD card slot; the USB HUB module comprises a USB HUB chip and a USB output port. Compared with the prior art, the all-in-one card reader can realize the functions of the all-in-one card reader of the USB interface and the functions of one-to-four of the USB HUB of the USB and has high practical value in the field of multifunctional computer.
Description
Technical field
The utility model relates to a kind of read-write equipment of portable memory apparatus, a kind of specifically All-in-One card reader with USBHUB.
Background technology
Card reader is a kind of specialized equipment.Have slot can insert storage card, ports having can be connected to computing machine.The storage card that is fit to is inserted slot, and port links to each other with computing machine and installs after the required driver, and computing machine just is used as a removable memory to storage card, thereby can pass through the card reader reading and writing memory card.By the kind branch of compatible storage card can be divided into CF card reader, SM card reader, PCMICA card reader and memory stick read write line etc., also have the double flute card reader can use two or more card simultaneously; Can be divided into serial port card reader (speed is very slow, seldom sees), parallel port card reader (computing machine that is suitable for early stage mainboard), USB card reader (speed is fast, and is easy to use) by the port type branch.USB interface on the existing computing machine is limited, and the USB peripheral hardware is more and more, and may cause when using USB flash disk can't Card Reader, stores and use wherein any all might can't finish lot of data.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of All-in-One card reader with USB HUB is provided.
The technical solution of the utility model realizes in the following manner, this a kind of All-in-One card reader with USB HUB, its structure comprises USB input port, card reader module, USB HUB module, described card reader module comprises card reader chip, SD/MMC draw-in groove, XD draw-in groove, MS/MSPro draw-in groove, CF/MD draw-in groove, TF/Micro SD draw-in groove, and described USB HUB module comprises USB HUB chip, USB output port.
The card reader chip is a processor GL826 chip.
USB HUB chip is a processor GL850A chip.
Described USB output port is provided with 4.
The beneficial effect that the utility model is compared with prior art produced is:
A kind of All-in-One card reader with USB HUB of the present utility model is provided with card reader module and USBHUB module, processor GL826 is responsible for USB changes the data input of All-in-One card reader, output conversion process, and processor GL850A is responsible for a USB changes the processing of a plurality of USB port.The utility model circuit is simple and reliable, can realize that the function of All-in-One card reader of USB interface and USB one drag four USB HUB function, have very high practical value in the multi-purpose computer field.
