Description

Multi-function card reader

technical field

The utility model relates to a card reader, in particular to a card reader which has at least one original memory card slot, and further includes a miniature hard disk slot, so that the flash memory card embedded in the slot can be connected with the Microdrives can access data from each other. Furthermore, the utility model still has at least one USB interface socket, and has a hub (Hub) function.

Background technique

According to present existing card reader, mainly simply read, overwrite or delete data to the flash memory card, so as to serve as a communication bridge between the computer and the flash memory card. With the continuous advancement of technology, storage devices are also developing towards thinner, lighter and smaller devices. For example, micro hard disks with a storage capacity of up to 10 GB have been developed by related companies and have entered the mass production stage. Because the size of these miniature hard drives is only 1.8 inches, they will be widely used in handheld electronic products, such as digital image capture devices for PDAs (personal digital assistants), digital cameras or digital video cameras, and even for handheld computers. It not only provides high-capacity storage space, but also greatly reduces the size of electronic products, which can be called a revolutionary product of storage equipment.

Because the connectors of these micro hard disks are 50 pins, although they are the same as the CF cards, only the definitions of the pins of the two are different, as well as the differences in appearance and size, so that they are not compatible. Therefore, if it needs to be connected with a computer, it is usually necessary to use the connector of the electronic product itself, or a connector suitable for these micro hard disks. However, the adapter only has a single purpose and occupies a connection port of the computer, such as a USB socket, which is not economical.

In addition, in order to facilitate the signal connection between the peripheral device and the computer, the USB interface is generally used as the connection. Due to the limited USB socket of the computer, most users use a hub with a USB interface in order to use a variety of peripheral devices, such as printers, mice, joysticks, scanners, MP3 players, digital cameras or digital video cameras. (Hub) is connected with the above-mentioned hardware devices to achieve the purpose of fast transmission. Therefore, the combination of hubs and card readers with the same USB interface is inconvenient. Therefore, how to make full use of product features to comply with consumers' operating habits, increase the added value of products, and effectively integrate product commonality is a difficult problem that the industry needs to overcome.

Detailed ways

In order to further disclose the specific technical content of the present utility model, first please refer to the accompanying drawings.

As shown in FIGS. 1 to 4 , basically, the multifunctional card reader of the present invention is composed of a casing 1 , a circuit board 2 , and at least one USB interface socket 3 .

Wherein, the housing 1 is formed by butting the upper cover 11 and the lower cover 12 for accommodating and positioning the circuit board 2 described later. The connecting portion of the upper cover 11 and the lower cover 12 corresponds to a power input terminal 27 provided on the circuit board 2, and a cover slot 13 is respectively opened at a position of a USB port 21, so that the above-mentioned components can be exposed. In addition, a plurality of mortise hooks 111 hang down from each corner of the upper cover 11 so as to be fastened to the predetermined fastening grooves 121 in the four corners of the lower cover 12, so that the upper cover 11 and the lower cover 12 form a fastening effect, but not with As a limit, known techniques such as screwing and adhesion can also be used for the docking of the two covers.
