Multimedia Connection Reader {MULTIMEADIA CARD READER}

The present invention relates to a multimedia connection reading device (multi-reader), and when the portable digital device is inserted into the connection sheet inside the receiving groove, the portable digital device can access the data in the memory card through the function of the transmission control circuit. do. In addition, the connection port can be connected to other different types of portable digital equipment, and it is possible to set whether to operate the transmission control circuit of the multimedia connection reader through a switch, and also to respond to different types of computer systems through the system controller. It is to be used.

As shown in FIG. 1, in general, when using the portable digital player B1, if it is necessary to read the data inside the memory card G, the portable digital player B1 must first be connected to the computer B by the connecting line B11. After connecting the card reader (C) to the computer (A) with the connecting line (C1), and then transfer the data using the computer (A) as a transmission output point, it is not only cumbersome to use, Alternatively, you can only transfer data if you have a notebook computer.

In addition, although the current memory card (G) has many types, the card reader (C) can generally be read only by a device such as a computer (A) or a notebook. Therefore, in various types of digital information facilities, if the internal data is to be stored in the external memory card G, the work becomes quite cumbersome. In addition, since the card reader (C) and the memory card (G) is small in volume, it is easy to carry, but it is quite inconvenient in use because it cannot be directly connected to a portable digital information equipment such as a portable digital player (B1).

Therefore, the technical problem to be achieved by the present invention is that the connection can be connected to different types of digital information equipment, can directly access the data inside the digital information equipment, the digital information equipment can directly read the data inside the memory card It is to provide a multimedia connection reading device to enable.

The present invention is to provide a multimedia connection reader (multireader), as shown in Figures 2a, 2b, and 3, the multimedia connection reading device (D) is a housing (D1), the bottom plate (D2) And a circuit board E, and the circuit board E is installed behind the housing D1 and covered by the bottom plate D2.

Among them, the housing D1 is provided with a receiving groove D4 and a connection sheet D3.

The circuit board E includes an insertion slot (or card slot) E1, a liquid crystal display E2, a connection port E3, a system connection port E4, a switch E5, a central processing unit E6, and a transmission control. The circuit E7, the battery E8 and the plug E9 are provided.

As a structural feature (refer to FIG. 4 together), the transmission control circuit E7 is connected with the central processing unit E6, and is connected to the connection sheet D3, the connection port E3 and again through the switch E5. It is connected to the insertion slot (E1) at the same time, the data displayed on the liquid crystal display (E2) through the central processing unit (E6) and data transmission between the card slot (E1), the connection sheet (D3), the connection port (E3) To control.

A portable digital device (or portable digital storage device) (B), for example, a device such as a PDA (Personal Digital Assistant), a portable digital player, a portable hard disk, etc., is inserted into the connection sheet D3 inside the receiving groove D4, When the memory card G is inserted into the card slot E1, the portable digital facility B accesses the data inside the memory card G through the function of the transmission control circuit E7. In addition, the connection port (E3) allows the connection of different types of portable digital equipment (B), it is possible to set whether to drive the transmission control circuit (E7) of the multimedia connection reader (D) through the switch (E5) Can be.

The system connection port E4 may correspond to a computer system of a different system type. For example, the system connection port E4 may be connected to a MAC or the like with a connection line so that the computer may directly read data in the memory card.

Among them, the battery E8 of the circuit board E is an operating voltage supply source of the components on the circuit board E, and at the same time, after being connected to the transformer F through the plug E9 (see FIG. 9), Normal power can be charged to the battery. In addition, when connecting the multimedia connection reading device (D) with a device such as a computer, by controlling the connection port E3 through the transmission control circuit (E7), it is possible to charge the power inside the computer with a battery (E8).

An embodiment of the present invention is as follows.

As shown in FIG. 5, after the digital portable player B1 is inserted into the receiving groove D4 of the multimedia connection reading device D, the connection sheet D3 is connected to the portable digital facility B. When the memory card G is inserted into the card slot E1, the portable digital equipment B can access the data in the memory card G or store the data in the memory card G.

As shown in FIG. 6, when the portable disk B2 is inserted into the connection port E3 of the multimedia connection reading device D and the memory card G is inserted into the card slot E1 again, the portable disk (B2) can access data in the memory card G or store data in the memory card G. As shown in FIG.

As shown in FIG. 7, when the digital camera H is connected to the connection port E3 of the multimedia connection reading device D, and the memory card G is inserted into the card slot E1, the digital camera H H) stores the captured image and sound files therein into the memory card G, and the liquid crystal display E2 displays data related to the connected data transfer operation, that is, data such as file transfer type, name and size. Display.

As shown in FIG. 8, the system connection port E4 of the multimedia connection reading device D is connected to the computer A through the connection line D, and then the computer A stores data in the memory card G. As shown in FIG. Read and write operations, and the insertion slot E1 is provided with a plurality of insertion slots E1 corresponding to the memory card G of different standards, so that the computer A is different. The data in the memory card G of the standard can be read simultaneously.

The multimedia connection reader of the present invention is compared with the conventional products as follows:
