Abstract

The present invention relates to a card reader; more particularly, the present invention relates to an all-in-one card reader capable of transmitting 32-bit data, which utilizes a first controller to read the data of a flash memory of various formats and convert them into a universal serial bus (USB) interface signal before outputting, and, then, uses a second controller to convert the USB interface signal into a 32-bit peripheral component interface (PCI) signal and output so as to increase the efficiency of transmission.

Description

1283415 IX. Description of the invention: [Technical field to which the invention pertains] ^ This is a type of card reading device, in particular, an all-in-one card reading device with 32-bit data transmission efficiency. [Prior Art] A conventional card reader capable of reading a plurality of types of memory cards is shown in FIG. 1. The card reader 1 includes an electrically connectable card 13 (for example, a compact flash card reader, C0MPACT FLASH). CARD, referred to as cf C Qing sad flash drive card, _ CARD, multimedia

And so on) the connection unit 10, which is connected to the controller 11 of the connection unit CCARD connected to the early 10,

The gift can convert the received data into 16-bit data and transmit it to the computer 2 via the ID. I _ _ But because the traditional card reader 1 has only 16 output transmission interface 12, the transmission speed is lower than 12m bits / sec, 'this transmission performance is poor. The transmission speed is slow and the capacity is low. SUMMARY OF THE INVENTION Accordingly, the object of the present invention is to provide a multi-in-one card reading device capable of improving the transmission performance of eight 32-bit poor transmission transmission performance. Read card provides - the combination of 32-bit data transmission performance 'n can be electrically connected to the complex memory card - the connection is premature, to transmit the corresponding record a first controller, connected to the connection unit, the information is changed to a lack of information, and the tenth is changed to a first of 16 bits: the second; the = 'receives the first signal' and is converted into - A 32-bit one-shot output, and an output connection to the second control 1283415 can receive and transmit the 32-bit second signal. [Comprehensive Mode] The foregoing and other technical contents, features, and effects of the present invention will be apparent from the detailed description of a preferred embodiment of the soil column. A preferred embodiment of the present invention will be described with reference to Figure 2 of the connection unit 30, a first batch. . . The interface 33 is included. - 31, - the second controller 32 and a crying plug connection = Μ can be, for example, a connection with a plurality of electrical pins ((4), U for a plurality of different specifications of the memory card 40~50 insertion, thereby electrically connecting the Wait for the memory card 4〇~5〇i by / any of them - and the first controller, to = send a file or video data, in this embodiment the memory card includes a security digital card township (4), s (four) Flash card 41, multimedia (secret _ ^ inter-private MMC) memory card 42, small-sized multimedia (Reduced Slzed Multl 仏 Card, referred to as RS-MMC) specifications of the memory card 43, multimedia 4 〇 version (title - 4. 〇) memory card 44, small size multimedia version 4.0 (Reduced S) zed Multl Media (5), referred to as rs-mmc 4〇) memory card 卡, card 46 upgrade 5 has recalled (MS-called card 47, ultra-small Memory stick (MS_DUO) flash memory card 48, mini secure digital (purchased i sd) card 49 and T-type flash memory (T Flash) card 50. The first & jiejie 3 1 and the second controller 32 can be packaged The first controller 31 is electrically connected to the connection unit 3G, and is selectively readable and electrically connected to the connection unit 3 Memory card which 4〇~5〇

6 1283415 The threshold v material is converted into a universal serial bus interface signal S1 (first signal) conforming to the universal serial bus (USB) specification, hereinafter referred to as the brain "face nickname. The second controller 32 is, for example, a USB_t〇_pci controller. The device is electrically connected to the first controller 31 for converting the coffee interface signal si into a peripheral component interconnection (Pedphera! Compo_ mterc〇nnect, abbreviated as pci) signal conforming to the peripheral component interconnection (PCI) standard. Magic (second signal), with T_pci signal, to output to - computer 4.

When any of the memory cards 4 to 5 is inserted into the connection unit %, the data in the memory cards 40 to 5G can be transmitted to the first production port via the connection unit %. The USB interface signal s 1 converted into the j 6 bit in the 3 1 is transmitted to the second controller 32, and the converted, output 32-bit PCI signal S2 is output to the computer 4 via the second controller 32.

With the card reading device 3 of the present invention, the data of the memory card 4()~% can be converted into a 32-bit PCI signal S2 output or the PCI signal S2 received by the computer 4 can be input to the PCI signal S2 after being properly converted. Such as the memory card 40~50, which can be increased to 66Mbits, the transmission performance between the card reading device 3 and the computer 4 is greatly improved. However, the above is only the preferred embodiment of the present invention, and does not limit the scope of the implementation of the present invention, that is, the simple equivalent change of the patent application and the description of the invention. Modifications are still within the scope of the invention. [Simplified description of the drawings]; and Figure 1 is a schematic diagram of a circuit block illustrating the conventional all-in-one card reader 7 8
