Description

Computer USB HUB and reader device

Technical field

The utility model relates to the hub and the card-reading apparatus of computer configuration, specifically is about a kind of circumscribed and built-in shared computer USB HUB and reader device.

Background technology

Before introducing the utility model, please hold USB (Universal Serial Bus USB (universal serial bus)) HUB and reader device are done a rough brief introduction.

It is to be undisputable fact that the function that computer provided enlarges day by day, but the peripheral equipment of host computer such as keyboard (Keyboard), monitor (Video), mouse (Mouse), printer (Printer), scanner (Scanner), modulator-demodular unit (Modem), digital camera (Digital Camera) and external connection box kinds such as (Outer Box) and quantity constantly increase, therefore the puzzlement on having produced these peripheral equipments and host computer being connected, for the connected mode that makes computer peripheral device and computer is simplified, according to and be born " general-purpose serial bus USB (Universal Serial Bus) " device, its device cooperates hub HUB, make each peripheral equipment can insert the jack of line concentration (seat) device HUB, make peripheral equipment and host computer obtain suitable binding via the plug terminal of USB.

Again because of computer through constantly bringing forth new ideas and improveing in recent years, its function and DATA PROCESSING and capacity are significantly promoted, so no matter be in personal host computer or the computer servo host, day by day bear the heavy responsibility of handling and storing huge data, known computer stores data in the assembly, and is the most general with Winchester disk drive (Hard Disk), diskette sheet (Soft Disk) and discs (CD) again.

Wherein Winchester disk drive is to belong to the fixed store tools that is fixed on the host computer, removeable disk machine (Mobile Rack) is fixing and is carried the dual-purpose type store tools, but no matter be that fixed disk machine or dual-purpose type extract disk drive, bulky because of it, weight is too heavy, therefore in fact and be not suitable for becoming the portable type store tools.

And diskette sheet and discs are the portable type store tools of general practicality, but the diskette sheet storage volume is limited to very much, though and the discs storage volume still can be satisfactory, unfortunately its area is excessive, it is not too convenient to carry, and general CD player can only read data and can't write data, and it writes data and needs to use in addition CD writer, therefore all nonideal storing media.

The as above shortcoming of portable type data storage media summary, thereby all satisfactory " memory card " of a kind of volume and capacity in response to and give birth to, its alleged " memory card Memory Card " comprises CF (Compact Flash), SD, MMC, Memory-stick ﹠amp; The memory card that the Smart-media equal-volume is extra small, known its is widely used on the computer peripheral products such as digital camera, MP3, language machine, and this memory card can be via " card reader Card Reader " access required information (because of including the Flash element in the card reader usually).

In sum, the HUB of the USB that can connect for most equipment and can respectively have its advantage for the reader device of great mass of data access, the utility model be about to above-mentioned both be combined as a whole, and provide and to supply circumscribed and built-in computer USB HUB and reader device, it makes circumscribed, its power supply can be supplied with via general direct current transducer, built-in can directly be placed on the computer disk frame and make, and supply with its power supply by the power supply unit in the computer, obviously the utility model is a simple and practical USB HUB and a reader device.
