Embodiment
According to the type of interface, card reader can be divided into: parallel port card reader, serial-port card reader, USB card reader, PCMICA card reader and IEEE1394 card reader.Wherein, parallel port card reader and serial-port card reader are because interface rate is slow or the installation inconvenience has been eliminated substantially; The PCMICA card reader is mainly used on the notebook computer, is used less on other equipment; And the IEEE1394 card reader is not because the interface of supporting also has popularly, and its application is also not too extensive; The USB card reader then is most popular in the market card reader, thus adopt in the utility model be the band USB interface card reader.
According to the kind of the storage card that can read, card reader can be divided into single function card reader and multifunctional card reader.Single function card reader generally can only read one type flash card, can only read the CF card as the CF card reader, and the SM card reader can only read the SM card, and the price of this class card reader is lower, but as above-mentioned, can not be compatible, there are many shortcomings; Multifunctional card reader then is can compatible multiple storage card, no matter is CF card, SM card, and perhaps the other types storage card can easily read, so can adopt multifunctional card reader in the utility model.
Be illustrated in figure 1 as the theory diagram of card reader in the utility model, as can be seen from the figure, be provided with card reader CPU (part among the figure in the solid box), USB interface, memory card interface circuit and EEPROM in this card reader.Be provided with PROCESSOR (processor), ROM, ARBITRATOR (arbiter), EEPROM CONTROL (EEPROM control circuit), VOLTAGE REGULATOR (supply voltage adjustment circuit), XCVR (exchange check register) and USB SIE (USB series flow open control circuit) among the described card reader CPU again.Nine kinds of memory card interface circuit are wherein arranged, comprise CF card, MD card, SMC card interface, MS card, MS PRO card, MS Doo card, SD card, mmc card interface and Flash Memory card.After inserting storage card in this card reader, the digital signal in the storage card is handled after the conversion through the card reader internal circuit, obtains the USB series flow, and delivers to next stage by the USB interface of card reader and handle.As shown in Figure 5, if the CPU in the control circuit of DVD burner integrated the USB control circuit, then data stream directly can be delivered to the CPU of DVD burner; As shown in Figure 6,, then must deliver to a USB controller earlier, deliver to the CPU of DVD burner after handling through this controller again if the CPU of DVD burner does not have the integration USB control circuit.Because above-mentioned nine kinds of plug receptacles all are compatible, so a public plug receptacle only need be set, just can connect above-mentioned nine kinds of different storage cards respectively.
Fig. 2 a to Fig. 2 d is the interface circuit figure of switching switch circuit and CF, SD in preferred embodiment of the utility model, MS card successively; Switching switch circuit shown in Fig. 2 a is used to realize handoff functionality, makes aforementioned public plug receptacle can connect dissimilar storage cards, and corresponding handover configurations explanation is arranged in the upper left corner of Fig. 4.Be illustrated in figure 3 as the interface circuit figure of SMC card in preferred embodiment of the utility model.
Be illustrated in figure 4 as the circuit diagram of card reader processor in preferred embodiment of the utility model (being the PROCESSOR among Fig. 1), as can be seen from the figure, what wherein adopt is the Au9360 chip, it can support nearly all on the market flash card, in the utility model, can adjust interface according to client's the needs or the needs of mould, the storage class that customization can be read
If the CPU of DVD burner then can directly be delivered to data stream by the CPU in the control circuit of DVD burner is integrated UCB control circuit.As shown in Figure 7 because integrated USB controller in DMN-86 that Infineon Technologies Corp. the provided series DVD control chip, so the USB peripheral pin in its left side can be directly with Fig. 1 on the left of USB interface be connected, promptly directly be connected with the USB interface of card reader.
If the CPU of DVD burner does not have the integration USB control circuit, then must deliver to a USB controller earlier, deliver to the CPU of DVD burner after handling through this controller again.As shown in Figure 8, PNX72xx family chip for PHILIPS Co., owing to wherein there is not the integration USB controller, so need add lastblock USB control chip, because control interface is a standard, so the USB control chip of main flow can be applied in here, comprise 1100 family chips of ICSI company, the AT43USB family chip of atmel corp etc.The USB interface of Fig. 8 left end also can directly be come from the front end line; The right of Fig. 8 is the connector end of DVD burner CPU.
In the utility model, can customize the interface of card reader with reference to the general-purpose industrial standard.Because its card reader can connect multiple storage card, multi-functional Card Reader DVD recorder of the present utility model can become a multi-functional digital home media platform.
