The first processing module 5 is electrically connected with a second processing module 6; the second processing module 6 is electrically connected with a fourth card reading circuit 61 and a fifth card reading circuit 62; the fourth card reading circuit 61 is electrically connected to the fourth card holder 24; the fifth card reading circuit 62 is electrically connected to the fifth card holder 25.

The second processing module 6 is also electrically connected with a reserved card reading circuit 7; the reserved card reading circuit 7 is electrically connected with a reserved card seat 8.

The data interface 3 adopts a USB3.0 interface.

The application enables the five-in-one card reader provided by the application to realize the expansion of the number of card reading through the conversion of the signal conversion module 4, the first processing module 5 and the second processing module 6. And the card holder set 2 is provided, the card holder set 2 comprises the first card holder 21, the second card holder 22, the third card holder 23, the fourth card holder 24 and the fifth card holder 25, so that card reading requirements applicable to a five-card camera can be met.

Wherein, the data interface 3 adopts a USB3.0 interface. USB3.0 is a new generation USB interface, and is characterized in that the transmission rate is very fast, can reach 5Gbps theoretically, is 10 times faster than the common High Speed USB (called USB2.0 for short) with 480Mbps, and completely exceeds IEEE 1394 and eSATA. The appearance is basically consistent with that of a common USB interface, and can be compatible with USB2.0 and USB 1.1 equipment. In the application, the data interface 3 adopts USB3.0 with national standard 24-pin TYPE-C plug, and the signals are completely symmetrical.

Further, the signal conversion module 4 adopts a SWITCH circuit.

Further, the first processing module 5 and the second processing module 6 are both 32-bit intelligent processor HUB modules.

Further, a standby power input port 9 is arranged at the opening of the shell 1.

The standby power input 9 is suitable for a five-in-one card reader provided by the application, and when the connection of the data interface 3 is only used, the power supply capacity of the power supply is possibly insufficient, auxiliary power supply is needed to be performed from the standby power input 9. Therefore, the service life of the five-in-one card reader provided by the application is prolonged, and the situation of insufficient power supply generated when the connected external equipment is old can be solved.

Further, the number of the reserved card reading circuits 7 and the reserved card holders 8 is 3.

Firstly, the five-in-one card reader provided by the application is applied to the field of camera card reading. The current technology is a camera product without four cards. Secondly, the reserved card reading circuit 7 and the reserved card holder 8 can be extended to 7. However, in the scenario where the embodiment of the present application is applied, the reserved card reader circuits 7 and the reserved card holders 8, which are 3 in number, are more reasonable choices in the application field of the present application.

And simply increasing the number of the reserved card reading circuits 7 and the reserved card holders 8 does not provide a better effect for the whole device. Too much increase results in an increase in the volume and cost of the overall device. And single, double, triple, and five cards are common camera cards in the art. Therefore, the application selects 3 reserved card reading circuits 7 and 3 reserved card holders 8 to be more reasonable choices in the applicable field of the application.

It should be noted that, in the embodiment of the present application, the reserved card holder 8 may not be used simultaneously with any card holder in the card holder set 2, and needs to be used in a staggered manner.

When the five-in-one card reader provided by the application reads a card, the card seat group 2 is required to be inserted into the SD card group. And the SD card set can shake when inserted, thereby causing poor contact. The SD card is typically placed into a card box. In this case, the auxiliary positioning hole 11 is provided, and the positioning piece provided on the card set box can be inserted into the auxiliary positioning hole 11, so that the problem of poor contact caused by integral shaking is solved.

Further, a buckle 12 is arranged on the top of the shell 1.

The clasp 12 is used for assisting the hand to exert better force when the SD card is pulled out from the card holder set 2.

the first processing module 5 is configured to match tasks and data transmission speeds on threads according to protocol contents and resource occupation conditions of the data interface 3, and optimally allocate signal bandwidths of four output channels;

the second processing module 6 is configured to optimize the corresponding process execution sequence according to the number of actually occupied signal channels, and together with the first processing module 5, it is used as a core control part of the card reader.

Wherein the second processing module 6 continues to expand the positions of the three reserved card reading circuits 7 and the reserved card holder 8.
