Description

Data access device for memory card

technical field

The utility model relates to data access equipment, in particular to a data access device for a memory card.

Background technique

After 1990, storage media developed using silicon semiconductor technology has gradually become mainstream products, and the new generation of storage media developed with flash memory as the main axis is silicon disc (Flash Memory Card). It is called a memory card or a flash memory card; compared with traditional floppy disks, CDs and other two storage media, the memory card is convenient to carry, power saving, data storage, data transmission rate, repeated reading and writing, As well as the performance of shockproof, moisture-proof and other functional characteristics, it far exceeds the above two traditional storage media.

Because silicon discs have such superior performance characteristics, various international electronic product manufacturers, such as Sony, Toshiba, Siemens, Matsushita, Samsung, SanDisk, etc. Various specifications of memory cards (or silicon discs) have been launched successively, and are widely used in various types of digital products; such as: PC card (PCMCIA ATA FlashCard), CF card (Compact Flash Card), SM card ( Smart Media Card), MMC card (MultiMedia Card), MS card (Memory Stick Card), SD card (Secure Digital Card), etc.

The above-mentioned silicon disks are mostly used in various portable digital devices, such as digital cameras, digital players, PDAs, etc., to store software data such as images, animations, and music; (such as personal computers, industrial computers, video decoders, etc.) for data circulation, so various forms of silicon disk data access devices (also known as card readers, or silicon disk drives) came into being born.

Commonly seen memory card reading devices use an independent card reader to connect with the external interface of the system host through a data transmission line, so that the data stored in the memory card can be edited, played, stored and executed by the system . However, it is not convenient to use such an external card reader to access data, because before accessing data, the above-mentioned work must be performed through a complicated connection mode, which is especially prone to connection errors, or during execution. The line is interrupted by external force, or the signal is unstable due to poor contact.

Contents of the invention

In view of this, the main purpose of the utility model is to provide an easy-to-use data access device for a memory card, which pre-arranges all electronic components necessary for accessing the internal data of the memory card in a base , and then install the base directly in the host of the system, preferably in the expansion slot of the host, such as the location of the floppy disk drive, etc.; and connect it to the motherboard of the system through a data transmission signal interface Then use another data line connected in parallel to transmit the signal of the interface to the external interface of the system host, so that the user can directly access the input data signal of the memory card through the system host, without having to connect other devices to Improve ease of use.

The technical scheme that the utility model adopts is as follows:

A data access device for a memory card, comprising: a base positioned in an expansion slot reserved by a system host and a panel, there is a storage space in the base, and a control unit is included in the storage space On the board, there is a control IC on the board to access and convert the signal format of the memory card. In addition, a data line is used to output the data signal from the board at the data signal output end of the control board. This data line is directly connected to the A specific interface on the motherboard of the system, and from this interface, use another data line to connect the external connection interface of the host backplane in parallel, so that this external interface can still be used by other devices.

Wherein, the specific interface of the system motherboard is a USB interface.

Wherein, the front of the base is a panel for plugging and unplugging the memory card, the panel is provided with more than a plurality of slots, and the back of the panel uses a signal connection mechanism to make the memory card contact with it after being inserted into the panel, so that the memory card can be inserted into the panel. The data signal is passed to the circuit configuration of the control board.

The data access device of the memory card of the present utility model overcomes the aforementioned defects of the common memory card access device (such as a card reader), and enables the user to directly access the input data signal of the memory card through the host computer of the system. , without having to connect other devices, which improves the convenience of use.

Detailed ways

The preferred embodiments are listed below, and the detailed structure and functions of the present utility model will be described in further detail in conjunction with the accompanying drawings.

As shown in Figure 1, the data access device of the memory card of the present invention includes: a base 1 with accommodating space, and a control board 11 is included in the accommodating space of this base 1, and the board 11 A control IC12 (such as SL11RIDE) is provided on the top to access and convert the signal format of the memory card; the front of the base 1 is a panel 13 for the insertion and removal of the memory card, and the panel 13 is provided with more than a plurality of slots 131, 132 On the back of the panel 13, a signal connection mechanism 14 is used to make the memory card contact with it after being inserted into the panel, so that the data signal can be transmitted to the circuit configuration of the control board 11. In addition, the connection mechanism 14 also includes a For the connecting rod 141 of returning card, in order to move back the action of card. On both sides of the base 1, there are also baffles 15, 16 that can fix the base 1 to the system host; as shown in FIG. In the reserved expansion slot 22, such as the position of the general floppy disk drive 23, or in other expansion slots 22.

Further in conjunction with what is shown in Figure 3, the data signal output terminal on the control board 11 outputs the data signal from the board with a data line 17, and this data line 17 is directly connected to the main board 24 of the system.
