Description

M245545 4. Creation Instructions (1) [Technical Field of New Type] This creation is to provide a card reader, especially a card reader that uses a USB interface to supply charging power and can also provide card data reading / writing functions. . [Previous technology] As USB is widely used in data transmission, because of its fast transmission speed and plug-and-play function, there is no need to restart the computer and other convenient features. The application method has brought a new era. Because of this, USB interfaces have been equipped on general computers in recent years. In addition, due to the rapid development of electronic technology, light, thin, short, and small have become the f of the handheld electronic device (Hand Held Electronic Device); such as digital cameras, mobile phones, digital cameras, digital portable $, electronic dictionary, personal Digital assistants, etc .; To meet the needs of data storage, it is usually equipped with SD, M, MMC, CF, or Xd ... memory card slots for memory card interfaces to accommodate memory cards with the same interface specifications. For auxiliary storage of data. Therefore, in order to obtain effective transmission between the computer host or the data, and to facilitate the use of memory cards with different interface specifications, you must use the "Card Reader (Card

Reader / Writer) "to connect to a computer. However, most card readers are useful for handheld devices that consume a lot of power. That is to say, the user is only used as a data interface to the electronic device. There is no direct computer, and at least one

This creation provides a connection interface, and the other end is connected with a controller and a charging module and the computer brain. In order to make your review more aware, the power supply of the host can also read through this: a card reader module with charging function, which can save the cost of installing a charger on the work desk. One end of an alpha-hai connection interface with a charging function can be connected to an electric unit; wherein the control unit 5 is connected to a write unit to charge the battery to a rechargeable battery; the write unit reads or Write at least one of the main features of this creation of a card reader with charging function, which is M245545

It is using -USB interface to provide a charging power. The charging module can use this charging power as the source of power.

Please refer to FIG. 1 and FIG. 2, which are electronic block diagrams and perspective views of a preferred embodiment of a card reader 1 with electrical functions, respectively. In Figure 1, a flash memory card of SD specification is used as the preferred embodiment of the card reader 1 of this creation. However, it includes, but is not limited to, other types of silicon drives such as MS-type memory cards, MMC-type memory cards, CF-type memory cards, XD-type memory cards, or micro hard disks using a CF 4USB interface, Or other types of memory devices. The card reader 1 of this creation includes a main body 10, a charging module Η, a control unit 12, a read / write unit 13 and a USB interface 14. The main body 10 constitutes the main outline appearance of the card reader}, and serves as a structure providing space and support for other components. The charging module 11 is disposed in the main body 10 and has a receiving slot 1101. The receiving slot 1 01 can hold and charge a plurality of rechargeable batteries.

One end of the USB interface 14 can be directly connected to a computer host, and the other end is connected to the control unit 12; wherein the control unit 2 can include at least a charging control IC and a read-write control I c (Figure (Not shown), so as to control a read-write unit 13 and a charging module respectively connected to the control unit 12! ≪ Made. In actual application, the USB interface 14 may also be considered to be a PS 2 interface that is currently commonly used, or a user interface of any other specification. When in use, after inserting a solid-state flash memory card in the slot 15, the computer host can read the solid-state flash memory card 1 2 1 through the USB interface 14 and the read-write unit 13 Data; for the same reason, the host computer can also write data to the memory card 12 through the USB interface 14 and the read / write unit 13

in. In this preferred embodiment, the specification of the SD memory card interface is used as the read / write unit 13. Therefore, the appearance contour and structure of slot 5 are designed to meet the specifications, dimensions and appearance of SD memory cards. When the power supply of the handheld electronic device is exhausted, the user can charge the rechargeable battery 102 therein, and the user only needs to put the rechargeable battery into the receiving slot 1 01, and the control unit 2 will drive the charging The module 丨 丨 uses the current of the host computer as a charging power source to automatically charge the rechargeable battery 102. One of the values is the appearance of the PCMCIA, which is well-known before. It is really a multi-slot method that can only benefit from the scope. 0 Please note the examples. ^ The combination of digital and size of USB (s as defined above) Inside, it is' The aforementioned SD memory card interface is only a read-write unit 13 and is not the only embodiment. The read-write unit 13 may also be an interface such as SD, MS, MMC, CF, xD, or other Of course, those who use the transmission interface of the signal are poor. Of course, the slot 15 f also needs to correspond to the transmission interface specification of the read-write unit. You can consider multi-slots or ln§le sl. t) Reader design. The presenter's is only a preferred embodiment of the present creation, and should not create a scope of implementation. That is to say, all those who apply for the creation of the original application according to this creation 3 and 2 should still belong to this creation patent.
